Keynote: Role of SPECT-CT imaging techniques in oncology
Time : 9:40-10:10
Biography:
Radiopharmaceuticals used in standard nuclear medicine for patients with breast cancer are a well-known source of ionizing radiation, emitting gamma-photon particles: Tumorotroponin cationic complexes such as 99mTc-Sestamibi/Tetrofosmin (MIBI/TF); radiolabelled somatostatin analogues 111In-Ocrteoscan/99mTc-Tektrotyd; 99mTc-MDP; 99mTc-Nanocoll, etc. The intensive tracer uptake of the different radiopharmaceuticals depends on the blood perfusion and their biodistribution, the proliferative activity of the tumor cells, the oxygen consumption, receptor status, and other factors of different tumors. Among the various visual methods used to assess malignant diseases new hybrid SPECT-CT imaging can provide accurate diagnostic information of the presence and extend of neoplastic diseases as well as unique data about tumor biological characteristics such as rate of cell proliferation or somatostatin-receptor overexpression intensity. The nuclear medical part of the hybrid SPECT-CT images gives information for the functional activity of the primary neoplastic process of the breast and the secondary metastatic lesions, while the CT image is needed for determining the anatomical subtract of the visualized from the scintigraphy "Hot" lesions. This reflects on the reduced number of false-positive and false-negative results and therefore increasing the sensitivity and specificity of the scintigraphic studies. The SPECT-CT exams find a different clinical value in oncology. Combined SPECT-CT images enables to discover occult primary tumors, to visualize loco-regional or distant metastatic spots for correct N/M staging, to evaluate effect of complex therapy. SPECT-CT images are applicable in radiotherapy planning to target precise functional gross tumor volume delineation. In conclusion, the introduction of multimodal SPECT-CT methods in nuclear oncology increased the diagnostic specificity and sensitivity of the nuclear medical diagnostic approaches, which is of an important clinical value in determining and planning individual therapeutic management in patients with malignant diseases.

Abstract:
Over the last decade, there has been a growing interest in mircoRNA (miRNA) and their utility in the field of Oncology. MicroRNA molecules are now being utilized as diagnostic and prognostic biomarkers for stratification of patient as well as therapeutic agents. MiRNA is a non-coding RNA which regulates the expression of various oncogenes or tumor suppressor genes. Alterations in the microRNA target binding sites and the microRNA itself, in tumors, have been implicated for their diagnostic utility in malignancies. Some of the tumor suppressors such as the p53 and phosphatase and tensin homolog (PTEN), are down regulated in most of the neoplasms. These are potential targets for miRNA. Recent research has also shown that miRNA would also be useful in identification and stratification of chemotherapy agents. MicroRNA might help distinguish patients with stable oligometastatic disease from patients with progression to polymetastatic disease.

Keynote: The design and properties of synthetic tissue/organ models
Time : 10:40-11:10
Biography:
Ozge Akbulut is an Assistant Professor at Sabanci University since February 2012. She received her BS in Materials Science and Engineering at Sabanci University in 2004 and her PhD from Massachusetts Institute of Technology (MIT, 2009) focused on cost-effective fabrication of biomolecular devices and surface science. She continued her studies as a Post-doctoral fellow in the Whitesides Group at Harvard University (2009–2011) on developing tools/techniques for resource-limited settings. Her main research interests include rheology modifiers and silicone-based composites. She also founded a company, Surgitate, on tactile surgical training platforms, in 2014.
Abstract:
Surgical stuff-in-training necessitate practice to improve their skill sets and the shift towards simulation-based trainings enables trainees to learn at their own pace and experience custom-based cases rather than responding to the immediate needs of the patients. Oncoplasty for breast cancer encompasses tumor removal and subsequent breast reconstruction; and there are several oncoplastic techniques to master for proper treatment of the patients. For training purposes, closest media to reality, fresh cadavers, are hard to obtain due to their price and/or unavailability. There is a need for a sustainable, reliable, and affordable platform to diffuse simulation-based trainings to medical curricula and provide trainings even in resource-limited settings. Silicone-based composite models can be designed and manufactured to fulfill the necessities of breast surgery such as precise incision, epidermal undermining, suturing, and resisting suture tension after excision of a considerable mass. We have shown the performance of such a stand-alone breast model for two oncoplastic techniques, “Batwing Mammoplasty” and “Modified Inferior Flap Rezai”. This model can be used in settings where it is difficult and/or expensive to find fresh cadavers. This cost-effective and practical solution also eliminates the need for chemical/cold storage and risk of infections/molding, thus making it a preferable tool for teaching hospitals and also for individual practice. In addition, the model is suitable to be used in self-diagnosis trainings, as well as a communication platform between medical stuff and patients.

Abstract:
The concept of fertility-preserving surgery in early cervical (stage IA 2 or IB 10) is radical trachelectomy. Trachelectomy is a conservative oncologic operation with aim to preserve fertility in early stages of cervical cancer female patients. Excised structures in trachelectomy are: Cervix, upper 1/3 of vagina, parametria and paracolpia, with preservation of uterine corpus. After removing the vaginal fornix and cervix, uterovaginal anastomosis with non-resorptive suture is performed. Indications for trachelectomy are, patients up to 45 years of age who wish to conserve fertility with negative lymph nodes, no distant metastatic disease, FIGO stage cervical cancer staged IA1, IA2, IB1 (tumor size ≤ 2 cm with negative lymph nodes), with adequate cervical length, no evidence of expansion of malignant process on the upper part of the cervical canal, squamocellular carcinoma, rarely cervical adenocarcinoma, negative lymph nodes intraoperatively, no metastatic disease, and clear resected margins. There is an ongoing debate regarding the need for uterine vessels preservation. Some authors have proved that the preservation of the uterine artery is associated with more favorable restoration of the reproductive function. Others claimed that preservation of the uterine vasculature is not necessary for fertility as obstetrical outcomes are similar to those of the historical vaginal radical trachelectomy cohorts.

Abstract:
Purpose: Breast cancer in Arab world has unique clinicopatholigical features including early onset, higher grade and higher HER2 amplification, the aim of this retrospective study was to assess the molecular spectra, frequencies, and distribution patterns of somatic mutations using next generation sequencing (NGS) in Arab women with breast cancer.
Subjects & Methods: 78 consecutive Arab women with breast cancer whose tumors had been evaluated using NGS were identified and retrospectively reviewed. We recorded patient characteristics, tumor pathological features, the rate of somatic mutations found on the NGS.
Results: The median age at diagnosis was 52.3 years (range: 37-82 years). 30 (38.5%) of the 78 patients were 50 years of age or younger. A familial history of breast cancer was documented in 30 (38.5%) patients. NGS revealed the following somatic mutation rates: TP53, 23%; ATM, 2.5%; IDH1, 2.5%; IDH2, 3.8%; PTEN, 7.7%; PIK3CA, 15.4%; APC, 7.7%; NPMA1, 1.3%; MPL, 1.3%; JAK2, 2.5%; KIT, 7.7%; KRAS, 3.8%; NRAS, 3.8%. DH1 and IDH2 were 2.5% and 3.8% respectively. Two patients (2.5%) had JAK2 mutations and both had an advanced triple-negative disease. Compared with Western population, Arab women have higher rates of APC, PTEN, KIT, KRAS, NRAS and DH1 somatic mutations and lower rates of TP53 and PIK3CA somatic mutations compared to Western women. ATM mutation rate was similar. Two novel somatic mutations were identified NPM1 and MPL with undefined role in breast cancer pathogenesis.
Conclusions: Our results revealed differences in the genetic profiles and mutation hotspots in Arab women with breast cancer compared to the reported genetic profiles of Western women with breast cancer. These results may have clinical implications in some of the actionable mutations and their targeted therapies once the roles of these somatic mutations in breast cancer tumorigenesis are more defined.

Abstract:
Next generation sequencing (NGS) technology is revolutionizing the diagnosis and treatment of chronic diseases and other fatal conditions, and its emergence as an affordable service is allowing doctors and patients easier access to potentially life-saving genetic data. This technology is cost-effective and delivers accurate and efficient results in a short period of time. NGS can now be incorporated into standard clinical practice. Our custom NGS panels target a group of genes that are known to cause specific genetic diseases or conditions. We have developed panels for cancer that can detect germline as well as somatic mutations in cancer causing genes. Our hereditary cancer panel targets genes that have been previously linked to a predisposition to common and rare forms of cancer such as leukemia, osteosarcoma, breast cancer, prostate cancer, pancreatic cancer, lung cancer, and skin cancer. We also developed two tests for sequencing somatic mutations in tumor driver genes. The first panel targets tumor driver genes using deoxyribonucleic acid (DNA) extracted from tissue biopsies that are flash frozen or paraffin embedded. The most recent addition to our testing menu has been the circulating tumor DNA (ctDNA) panel, more commonly known as liquid biopsy. 'Liquid biopsies' could revolutionize cancer detection by sequencing ctDNA. ctDNA are pieces of DNA from dying cancer cells found in the blood of cancer patients. We are utilizing a minimally invasive method that uses only a few millilitres of plasma from patients to detect mutations in genes commonly found mutated in solid tumor type cancers. The test is intended to identify the presence of circulating tumor DNA and identify mutations in genes associated with cancer at a very low allelic frequency. The test can be used for the monitoring of cancer remission after treatment such as chemotherapy, radiation or surgery as well as direct new therapies that target somatically mutated genes identified through clinical NGS.

Title: All high risk? Pathologic extracapsular extension in the era of human papillomavirus associated head/neck cancers
Time : 13:00-13:25
Biography:
Tarek Dufan is currently serving as a Medical Director of Bismarck Cancer Center. He is also a Cancer Committee Chair, CHI St. Alexius Health Center, Bismarck, ND and also acting as an Associate Professor at University of North Dakota and is affiliated with St. Alexius Medical Center. He received his Medical degree from University of Tripoli School of Medicine and has been in practice between 11-20 years. He is one of 2 doctors at St. Alexius Medical Center who is specialized in Radiation Oncology.
Abstract:
Purpose/Objective(s): Extracapsular extension (ECE) is an established risk factor for head/neck cancer (HNCa) recurrence and mortality; however, it is unknown if nodal ECE remains a negative prognostic factor in Human Papillomavirus (HPV)+ HNCa.
Materials & Methods: Retrospective multi-institutional comparative outcomes analysis of patient- and tumor-specific factors was done by HPV association. Eligible patients had pathologic confirmation of ECE for squamous cell carcinoma of the HN involving the oropharynx (OP), oral cavity (OC), or unknown primary (UP), and underwent curative-intent therapy. Patients with metastatic disease at diagnosis, unknown HPV/p16 status, or <3 month follow-up were excluded.
Results: Between the period from 2003 to 2014, 76 patients were found eligible for the present analysis. The median age at diagnosis was 60 years (range 29-82), with 46 OP cases, 28 OC, and 2 UP. Forty-one patients had HPV+ tumors.All but 5 patients had therapeutic neck dissection, and the primary site was resected in 65 patients. For resected primary cases, 38, 23, and 4 patients underwent adjuvant chemoradiotherapy (CRT), radiotherapy (RT) alone, and no adjuvant therapy, respectively. For 9 patients who underwent definitive RT, 7 received concurrent CRT. Of note, 40% of HPV+ and 35% of HPV– patients did not receive chemotherapy (p=NS). The median number of nodes excised and involved were 27 (1-92) and 2 (1-32), respectively. At a median follow-up of 26.3 months (1.4-104.0; median 34.1 for survivors), 52 patients were alive (48 without recurrence, 4 with salvaged recurrence) and 24 patients had died (21 of HNCa).Patterns of failure included local (n=6), regional (6), locoregional + distant (6), and distant only (4). In comparing the HPV+ and HPV– groups, disease-free and overall survival was superior for the HPV+ group (p<0.01; Table). HPV+ cases were more likely to be male (93% vs. 51%), undergo definitive RT (30% vs. 20%), have higher stage (73% vs. 49% stage IV) and larger nodal size (median 3.6 vs. 1.9 cm), and less likely to have undergone resection of primary (78% vs. 94%). There were no differences in number of lymph nodes sampled or involved or in follow-up between the groups.
Conclusion: HPV+ HNCa with ECE has an excellent prognosis despite the propensity for advanced AJCC stage and large pathologic nodal size. This excellent prognosis persists without the use of chemotherapy. Prognosis in the HPV– population with ECE remains poor despite therapeutic escalation using modern multimodality therapy (surgery, chemotherapy and radiation). ECE in the HPV+ population should be re-evaluated as a negative prognostic factor and indicator for therapeutic escalation.

Abstract:
With the increased awareness and use of breast cancer screening programs, detection of nonpalpable lesion of breast is also increasing in incidence. Previously, wire guidance under ultrasonography was used for localization of these occult lesions, and in the second stage, sentinel node biopsy (SNB) was taken under radioactive guidance or blue dye injection. We conducted a study to combine radioactive‑guided occult lesion localization (ROLL) with SNB. We concluded that ROLL is an efficient method for the detection of these occult lesions, enabling more effective planning of skin incision, precise excision of the lesion with minimal normal tissue edge excision, and ultimately better postoperative cosmetics. When combined with SNB, it effectively decreased the intraoperative time. Radio‑guided occult lesion localization (ROLL) is a new method for the localization and resection of nonpalpable breast lesions. It has emerged as a novel technique in the surgery of impalpable breast lesions implementing practically the same technique of detecting sentinel nodes, namely detection of radioactivity by gamma probe.

Title: The decrease of MITF, a crucial melanoma transcription factor does not induce marks of epithelial-mesenchymal transition, maintains the proliferation and invasivity, but diminish the differentiation of melanoma cells
Time : 15:00-15:25
Biography:
Jiri Vachtenheim received his MD from the Medical School of the Charles University, Prague in 1981 and PhD degree in 1985. Parts of his Post-doctoral studies were performed as fellowships in Great Britain and Belgium. He is now an Associate Professor and Department Head at the Institute of Medical Biochemistry and Laboratory Diagnostics, First Faculty of Medicine, Charles University, Prague, Czech Republic. He has published more than 40 papers in reputed journals and has served as a reviewer of many publications and grants.
Abstract:
Melanoma is an aggressive cancer of the skin in which microheterogeneity appears early after its onset. Epithelial-mesenchymal transition (EMT) is a key process associated with the progression of malignant tumors. It is believed that low levels of MITF, a melanoma pivotal transcription factor, are associated with EMT-like phenotype. The phenotype switching model in melanoma predicts that low-MITF protein levels favor tumor cell invasivity, but slow down proliferation and inhibit differentiation, while high-MITF cells are highly differentiated and rapidly proliferating. To verify this in the cell culture model, we have developed the Tet-On lentiviral inducible system based on the Tet-pLKO-puro plasmid with cloned shRNA to stepwise decrease MITF level in six melanoma cell lines with high MITF. The MITF levels substantially decreased after the addition of doxycycline. Surprisingly, all cell lines proliferated equally despite the low MITF protein level and did not seem to be more invasive. Proteins characteristic for EMT were either present or lacking without any changes. BCL2 protein did not display any change. The only changes were the decrease of E-cadherin in MeWo cells and increase of N-cadherin in SK-MEL-28 cells, two typical hallmarks of EMT. Genes responsible for pigmentation (TYR, TRP1 and 2), the expression of which requires MITF, were decreased after addition of doxycycline in low-MITF cells, by RT-PCR. Experiments in nude mice xenografts are underway. In sum, the results predict that MITF levels generally may reflect rather than directly cause the EMT in melanoma in vitro.

He has closely worked with Dr. Sugarbaker the late President of the American Association of Thoracic Surgery, Dr. Scott Swanson a World Leader in VATS Surgery and Dr. Steve Menzer, an expert in Lung Surgery and Esophagectomy in North America.
Abstract:
Lung cancer is an aggressive and heterogeneous disease. Advances in surgical, radiotherapeutic, and chemotherapeutic approaches have been made, but the long-term survival rate remains low. After the Surgeon General's 1964 report on smoking and health, mortality from lung cancer among men peaked and then fell; among women, the peak occurred later and a slight decline has occurred more recently. Lung cancer screening reduces mortality from lung cancer. We will discuss recent updates on guidelines, lung cancer screening and management of early detected lung cancer.

Abstract:
Autophagy is a key cellular process for the degradation of cellular constituents such as invading viruses, damaged organelle and long-lived proteins and plays critical roles in many physiological and pathophysiological conditions. A variety of nanomaterials, including carbon, metal, and rare earth oxide nanoparticles, have been demonstrated to induce elevated level of autophagy in different cell types. Recent studies have demonstrated that, in addition to elliciting bulk and non-selective autophagy, some nanomaterials can also induce selective autophagy, which target particular intracellular constituents for degradation. In this talk, I will present the latest results from our laboratory, which demonstrated that engineered nanomaterials, through inducing selective autophagy, enhance clearance of mutant Huntingtin and mutant p53, two types of aggregate-prone intracellular proteins that play critical roles in Huntington's Disease and cancer. These studies may pave the way for the exploitation of nanomaterial-induced autophagy for therapeutic applications towards cancer and neurodegenerative diseases.

Abstract:
Background: Molecular diagnostic testing has become an integral part of the evaluation of patients with metastatic colorectal cancer (CRC). However, expanded mutational testing often identifies mutations with unclear clinical, therapeutic or prognostic implications. One such example is BRAF mutations which occur outside of codon 600 (non-V600BRAF mutations).
Methods: We completed this multicenter, retrospective cohort study to fully characterize the clinical, pathologic and survival implications of non-V600BRAF mutations in metastatic CRC. We identified and pooled all patients with CRC in whom non-V600BRAF mutations were identified from NGS databases at three large molecular genetics reference labs.
Findings: A total of 9643 patients with metastatic CRC underwent NGS testing. We identified 208 patients with non-V600BRAF mutations, which accounted for 21.5% of all BRAF mutations. The estimated prevalence of non-V600BRAF mutations in all patients tested was 2.2%. Cancers with non-V600BRAF compared with V600EBRAF mutations were found in patients who were significantly younger (58 vs. 68 years; p<0.0001), less likely to be female (46% vs. 65%; p=0.0008), and had less high grade (13% vs. 64%; p<0.0001), or right-sided primary tumors (36% vs. 81%; p<0.0001). Median overall survival (OS) was significantly longer in patients with non-V600BRAF mutations compared to those with V600EBRAF-mutant metastatic CRC (OS: 60.7 months vs. 11.4 months; p<0.0001). In multivariate analysis, non-V600BRAF mutation remained independently associated with improved OS (HR: 0.18; p< 0.0001).
Interpretation: Non-V600BRAF mutations occur in approximately 2.2% of patients with metastatic CRC and define a new subtype of CRC with an excellent prognosis.

Abstract:
Conservative breast therapy (CBT) means lumpectomy or segmental mastectomy followed by radiotherapy. Both surgery and radiotherapy produce a wide spectrum of breast changes that appear on different imaging modalities. Certain radiologic features of these benign breast changes may simulate radiologic patterns of tumor recurrence that occurs at a rate of 2.5% per year between 2 and 6 years after treatment. Sometimes the differentiation between these two entities is a challenging diagnostic dilemma; thus, the interpreting radiologist must be familiar with the expected chronologic appearances of the conservatively treated breast. Consequently, radiologists should be able to decide whether to recommend follow up or request for pathological correlation. Basic imaging modalities are: Mammography, Ultrasonography and MRI. MRI is now recognized as a reliable powerful tool for follow up of treated cases of breast carcinoma. Functional MRI perfusion is effective in monitoring the response to chemotherapy. Recent research studies address diffusion MRI as a promising tool that may provide an earlier biomarker for tumor response than changes in tumor size.

Abstract:
This research deals with the effects of natural pigments (chlorophyll and anthocyanin) on the secondary (Engineering) bonds in the poly(methyl methacrylate) which play an important role on the physical and chemical properties of polymer. Natural pigments extracted from plants by a simple method shows a good agreement with the standard one which characterized by Ultraviolet–Visible (UV–Vis) Spectroscopy and Fourier Transform Infrared (FTIR) Spectroscopy. The blend of poly(methyl methacrylate) (PMMA) with pigments were characterized by FTIR, differential scanning calorimeter (DSC), hardness, and density. Hardness of PMMA decreases as concentration of pigment increases while density show decrease by anthocyanin comparatively higher than chlorophyll. This is due to the presence of many hydroxyl groups in anthocyanin molecule than in chlorophyll molecule, so it diffuses more in the PMMA polymer and creates voids between the polymer chains which destroy secondary bonds. Results show that anthocyanin shows higher depression in glass transition temperature (Tg) of PMMA than chlorophyll where its maximum effect is 3%. From glass transition temperature( Tg) data for a linear unbranched polymer , the energies provided by the pigments to destroy Van der Waals bonds (secondary or engineering bonds) as a function of pigment concentration result in (lowering Tg value of the polymer), partially raptured of the secondary bonds especially for molecule with abnormal energy than others.
From the above table, it seems that pigments are providing small amounts of energy to depress Tg of the PMMA biopolymer. All results showed that natural pigments enter between polymers chains and destroy secondary bonds and act as plasticizers ( lowering the rigidity of the polymer chains) of poly (methyl methacrylate ).

Abstract:
Introduction: Chemotherapy medication errors are source of some morbidity and significant mortality. Prevention from these complications should be addressed to the new staff and nurses in the oncology wards.
Method: A systematic review on the publicated chemotherapy medication errors and outcomes was done, although it must be believed that the reported cases are tip of an iceberg of errors that are not published.
Results: Important examples of errors were: Miscommunicated verbal orders, Total course or cycle dose given every day inspite of weekly or every two weeks or over three consecutive days; Lack of pertinent patient health care information (i.e. lab data and patient demographics such as age, height, weight and surface area); Use of incorrect patient information/lab data or the information/lab data for another patient; Excessive interruptions during order processing or dose preparation (Phone, patients’ ring, pagers, etc); Poor packing and labeling by manufacturers; Poor communication between pharmacy and the nursing and medical staff; Use of abbreviations of drug names (example: Vin for Vinblastin, Vincristine and Vinorelbine); Similar sounding drug names within the therapeutic class (example: Doxorobicin, Daunorubicin); Use of trade names which may vary even for generically available agents; Lack of warning stickers or labels to prevent inadverent intrathecal administration of drugs such as Vincristine, Vinblastine, Doxorobicin and Daunorubicin; Failure to round drug doses which potentially leading to a 10 fold overdose if the decimal point is not seen; Widely differing dosing regimens for the same tumor type (example: various regimens of 5-Fluorouracil in colorectal cancer) or in various tumors; Use of outdated lab data (example: serum creatinin or liver function tests for dose modification of certain medications). Also there are some error prone medical transcriptions, for example: qd or QD for daily doses; qn, qhs, hs, bt for bedtime; x3d for x 3 days; per OS for orally or PO (misread as for left eye!); Failure to use a zero before a decimal point when the dose is less than a whole unit (example: avoid .1 mg instead of 0.1 mg).
Conclusion: Chemotherapy medication errors are not infrequent and should be considered that they may happen in your ward, by you and your personnel’s, so a patient safety committee and annual education of all the staff is advisable, although new nurses should be trained on arrival. The guideline and continuous education program should be considered. Observation of trainees by authorized staff is suggested.

Abstract:
Objective: The urachal cancer (UrC) is a rare type of bladder cancer. The management of UrC is mainly surgical, the role of neoadjuvant and adjuvant chemotherapy is not well defined due to the rarity of this disease, the staging of this disease using Sheldon staging system is complicated and does not stratify recurrence risk well. Poor risk features in UrC is not well described. We report an analysis of the clinicopathologic features, treatment outcomes, and prognostic indicators of 174 cases.
Study Design & Method: We conducted a retrospective study of patients with a confirmed pathological diagnosis of UrC at MD Anderson Cancer Center between 1985 and 2016. The medical records were retrospectively reviewed for demographic, clinicopathological and treatment modalities including surgical and chemotherapeutic agents (type, number of cycles and lines of chemotherapy treatments) used and outcome information were collected. Median overall survival (OS) and recurrence-free survival (DFS) were calculated using Kaplan-Meier curves, and survival rates were compared by the log-rank test. The Cox proportional hazard model was used for univariate and multivariate estimation of hazard risk ratios and 95% confidence intervals (CI) for factors that correlated with survival and disease recurrence after resection.
Results: A total of 174 patients with pathologically confirmed UrC were identified and included. The characteristic of the 174 patients are summarized .The median age 49.9 years (22.8–81.8), with a male to female ratio of 1:1 (50.1%: 49.8%). 75.9% were white, 80.5% had a primary tumor in the bladder dome. Mucinous pathology was the most common histological type (51.7%). Eighty five patients (48.9%) had a locally advanced disease with local extension to the bladder (Sheldon stage 3A), followed by 4B distance de novo unresetable metastasis in 34 (19.5%) with 9 (26.5%) went to have consolidative surgery. Seventy patients (40.2%) had an en bloc surgical resection of the primary urachal ligament. Overall survival based was analysed based on Sheldon stage, the median overall survival of 2A (80 months), IIIA was 75 months which was superior to IIIB (30 months) , IIIC (30 months) , IIID (30 months), IVA (30 months), IVB (23 months). There is a clear separation between IIIA and IIIB-IVA and IVB, where IIIB with local extension to abdominal wall has similar survival to stage IVA where patients have metastases disease to the regional lymph nodes.
Conclusion: Following surgery for UrC, high risk criteria with poor outcomes include node positive, margin positive, peritoneum involvement, or lack of en-bloc resection of the umbilicus. Locally advanced disease (IIIB) has similar prognosis like advanced stage (IVA-B). We propose a new clinicopathological staging system that correlates with survival.

Title: Upper gastrointestinal surgery: National management trends and outcomes AliAldameh
Time : 12:20-12:45
Biography:
Ali Aldameh is Certified in Surgery, Thoracic Oncology and Thoracic Surgery. He received his Advanced Thoracic Surgical Education in Harvard Medical School, Boston USA at Brigham and Women's Hospital. Following that, he completed an advanced fellowship in Minimally Invasive Thoracic and Foregut Surgery at Harvard Medical School. He was mentored by US leaders in their field of Thoracic Surgery who followed the tradition of pioneers in their fields, including Dr. Pearson in Toronto, Luketich in Pittsburgh, Orringer. He has closely worked with Dr. Sugarbaker the late President of the American Association of Thoracic Surgery, Dr. Scott Swanson a World Leader in VATS Surgery and Dr. Steve Menzer, an expert in Lung Surgery and Esophagectomy in North America.
Abstract:
Upper gastrointestinal surgery comprised of the separate disciplines of oesophagogastric (OG) and hepato-pancreato-biliary (HPB) surgery which includes the operative care of the most complex cancers in alimentary surgery. Historically, any given general surgeon would see relatively few cases each year, resect even fewer and outcomes were notoriously poor. The emergence in the last decade of data from North American centres reporting improvements in outcome following concentration of workload into more specialised units has had a profound influence both on clinical practice and organisational infrastructure. We will discuss the national trends for complex upper GI malignancy treatment.

Title: Fertility sparing approach in young patients with early stages of endometrial cancer
Time : 12:45-13:10
Biography:
Katarina Jeremic has completed his PhD from University in Belgrade, Serbia, She is the Chief of Gynecologic Oncology Department at Clinic of Ob/Gyn, Clinical Center of Serbia and member of many scientific projects related to Cancer and Pregnancy. She works as a Lecturer/Associate Professor of Gynecology and Obstetrics at the Medical School, University Belgrade. She has 50 publications in CC/SCI expanded and JCR indexed. She is an acitive participant at more than 50 international congresses, with total number of publications about 150.
Abstract:
Endometrial cancer is the most common cancer of female genital tract and female patients less than 40 years may account for 3-14% of all endometrial cancers. The promising fact is that in women <45 years, the tumor is mostly low grade disease localised to the endometrium, whereas survival is almost about 100%. An individualized and multidisciplinary approach to each patient and intense follow-ups are the current recommendations for fertility sparing. Conservative approaches of early-stage endometrial carcinoma includes hormonal therapy in selected group of young patients with endometrial carcinoma, age less than 45 years and wishes fertility, showing low grade 1 endometrioid adenocarcinomas (by 2 gynoncology pathologists review) limited to the endometrium with MRI excluded myomaterial invasion, without evidence of limphovasculare space involvement or extra uterine disease. Careful and accurate pretreatment assessment of patients considering conservative therapy includes radiologic imaging, hysteroscopy preferably but also contrast-enhanced radiologic imaging -MRI imaging of the ovary (5% of patients with endometrial cancer have synchronous primaries tumors). Repeating endometrial biopsies by hysteroscopy every 6 months has been recommended, until there is a complete response or achieving pregnancy. Surgery is recommended if there is no response after 6 months of medicational treatment. Hormonal therapy that could be applied is progestins which inhibits the estrogenic effect and suppresses cell proliferation (medroxy progesterone acetate, megestrl acetate), GnRh analogues, local gestagens (IUD), oral natural progesterons, aromatase inhibitors, even three step endoscopic (hysteroscopic) resection - removing tumour surrounding endometrium and myometrium. Fertility after treatment is not guaranteed, even there had been recorded reduced fertility of those treated, and there is a significant need of ART (18-60%).

Title: Regulation of LncRNA-MIF in c-Myc homeostasis
Time : 13:10-13:35
Biography:
Mian Wu has completed his graduation from Nanjing Normal University in 1981 (BS) and obtained his PhD degree from Columbia University, USA in 1988. He then continuously conducted his Post-doctoral research at Harvard University during 1988-1991. Thereafter, he moved to Singapore as an Assistant Professor at School of Biological Sciences of National University of Singapore. From 2000, he worked as a full Professor at University of Science and Technology of China in Hefei, Anhui. His research interests focus on molecular mechanisms for p53-regulated tumor development and regulation of non-coding RNA in tumor metabolism. He has published more than 60 research papers in international peer-reviewed journals with more than 2900 citations.
Abstract:
c-Myc is one of the most important proto-oncogenes and is activated in over half of human cancers. However, it remains unclear how the c-Myc protein level is regulated. Here we show that lncRNA-MIF (c-myc inhibitory factor), a c-Myc-induced long non-coding RNA, acts as a competing endogenous RNA (ceRNA) for miR-586 and reduces the inhibitory effect of shared miR-586 on Fbw7, an E3 ligase for c-Myc, leading to increased Fbw7 level and subsequent c-Myc degradation. This creates an autoregulatory feedback loop between c-Myc and Fbw7 that involves both a long and a micro noncoding RNAs. Interestingly, levels of all components of this network including c-Myc, lncRNA-MIF, miR-586 and Fbw7 are found to be higher in tumor cells than in normal cells. The c-Myc-lncRNA-MIF-miR-586-Fbw7 axis represents a novel mechanism by which c-Myc homeostasis is finely regulated. Additionally, lncRNA-MIF is able to inhibit the glycolysis and tumorgenesis via suppressing c-Myc.

Abstract:
Spirituality is an essential element of person-centered care and a critical factor in the way patients with cancer cope with their illness from diagnosis through treatment, survival, recurrence and dying. Despite the difficulty in clearly defining and measuring spirituality, a growing literature describes its importance in oncology and survivorship. Studies have indicated a significant relationship between spirituality and quality of life. Spirituality, in its broadest sense speaks to the meaning patients find in their lives especially during times of stress, illness and dying. Religious/spiritual beliefs influence patients' decision-making with respect to both complementary therapies and aggressive care at the end of life. Measures of spirituality and spiritual well-being correlate with quality of life in cancer patients, cancer survivors, and caregivers. Spiritual needs, reflective of existential concerns in several domains, are a source of significant distress, and care for these needs has been correlated with better psychological and spiritual adjustment as well as with less aggressive care at the end of life. Spiritual distress, as a diagnosis, requires attention and treatment just as any other clinical symptom. Spiritual resources of strength need to be identifies and recognized as positive factors in patients' coping. Finally a treatment plan needs to include the spiritual as well as the physical and psychosocial issues of patients. Studies also show that while nurses and physicians regard some spiritual care as an appropriate aspect of their role, patients report that they provide it infrequently. Many clinicians report that their religious/spiritual beliefs influence their practice, and practices such as mindfulness have been shown to enhance clinician self-care and equanimity. Challenges remain in the areas of conceptualizing and measuring spirituality, developing and implementing training for spiritual care and coordinating and partnering with chaplains and religious communities. Integrating spirituality as an essential domain of care will result in better health outcomes, particularly quality of life for patients across the trajectory of cancer care.

Abstract:
Introduction: In literature some studies suggested that in the cell culture of cancer cells (in vitro), mega doses of vitamin D has anti-proliferative effect and inhibits cell growth, also in some clinical (in vivo) studies patients having solid malignancies poor prognosis is associated with vitamin D3 deficiency and replacement of vitamin D3 might have positive impact on prognosis. However, some of the results of the studies were against this suggestion. Therefore, in the current study we aimed to do a systematic review to compare the clinical, pathological features and survival rates in patients with early breast cancer having regular vitamin D3 replacement or not.
Method: Medline (Pubmed Central), Scopus, ISI, ISC, EMBASE, Science Direct and Google Scholar was surveyed. Inclusion criteria for this study were all review literatures, case reports, clinical trials and in vivo studies about the effect of vitamin D supplementation, blood level of vitamin D life styles, nutritional habits and also in vitro studies about vitamin D and cell growth or tumor suppression. Exclusion criteria were non-English language and case reports that were addressed in the review literatures.
Results: 5 review literatures, 12 case reports and 6 in vivo studies had inclusion criteria, so we critically studied about their material and methods. The results of the included studies on the association between cancer risk and vitamin D were much less consistent. Only those studies that prospectively examined the vitamin D3 serum levels in relation to risk of colorectal cancer are homogeneous: they all reported inverse associations, although not all reaching statistical significance. 4 case–control and 3 prospective studies were included. 3 case–control studies observed no correlation between the risk of NHL and vitamin D intake. Polesel et al. (2006) found an inverse association between vitamin D intake and NHL risk. In the prospective study of Freedman et al. (2007), no relations were found between 25-VD levels and mortality of NHL. Using data of the Health Professionals Follow-up Study, Giovannucci et al. (2006) calculated that an increment of 25nmol/l of the predicted 25-VD levels was associated with a, non-significant, risk reduction of NHL.
Conclusion: Vitamin D deficiency has been linked to several common cancers, including cancers of the breast, colon and prostate. Most of in-vitro studies are in favor of the impact of vitamin D on prevention of cancer cell proliferation, and healthy nutritional habits including sea foods and Omega 6 intake may prevent from breast, colon and prostatic cancer; but nutritional habits are more relevant and clinical evidence for Vitamin D supplementation for cancer patients is weak, yet controversy has not been resolved, except for elderly patients with bone metastasis who previously were on vitamin D due to osteoporosis.
