361 Background: Primitive neuroectodermal tumours (PNET) of the kidney are rare tumours with aggressive behaviour. This study was conducted to review the diagnosis and management of patients with renal PNET at our centre. Methods: This was a retrospective study conducted at a tertiary cancer care centre in Mumbai, India. The demographic and clinical data of 17 patients treated by the uro-oncology services were retrieved from electronic medical records. Descriptive analysis was performed for baseline characteristics.Overall & progression-free survival was determined using the Kaplan Meier method. Cox regression was used for multivariate analysis. Results: There were 12 male and 5 female patients in this cohort with a median age of 27 years. At diagnosis 2 patients had metastatic disease and 15 patients had non-metastatic disease. Median follow up in this cohort was 22 months (range 2-30 months). Presenting complaints were hematuria, abdominal pain, flank pain, fever, bone pain, and incidentally detected renal mass. All patients were Mic -2 positive and 13 were FLI-1 positive on immunohistochemistry. Fourteen patients underwent radical nephrectomy. One (5.9%) patient received both neoadjuvant and adjuvant chemotherapy, 8 (47.1%) received adjuvant and 2 (11.8%) received palliative chemotherapy upfront. Eight patients received adjuvant radiation to the renal bed.There was disease progression in12 patients,10 of 15 patients with non metastatic disease at diagnosis eventually developed metastasis.The median progression free survival (PFS) was 10.55 months.The pathological feature that was associated with a shorter PFS was tumor size ⩾10 cm(p = 0.044).The median overall survival was 20.04 months (95% CI 9.49 -not reached). The presence of metastasis and treatment received significantly impacted overall survival (OS). Median OS in patients with non-metastatic disease was not reached versus 14.1 months in those with metastatic disease (p = .019).The median OS in patients treated with multimodality approach was 20.11 months. Patients did not undergo surgery had a median OS of 5.45 months (p < .001) and those who did not receive any chemotherapy had a median OS of 4.57 months (p = .024).Thus, patients who received multimodality treatment had better outcomes. Conclusions: PNET kidney is an aggressive tumor which should be treated with a multimodality approach. Tumor size ⩾10 cm was an adverse prognostic factor.

Abstract Introduction Gynecologic malignancies are an increasingly common proportion of central nervous system metastatic disease. As genetic sequencing technology improves and becomes more accessible, mutations associated with CNS metastasis are easier to elucidate. The aims of this case series and systematic literature review are to describe the patient population with CNS metastatic disease from a gynecologic primary, and to investigate why the proportion of CNS metastasis from gynecologic malignancies is increasing. Ultimately, we hope to improve understanding of this subset of metastatic CNS malignancies and improve management strategies. Methods A literature review of articles describing patients from 1990–2020 who were diagnosed with CNS metastasis from a known gynecologic primary malignancy was performed. Demographics, cancer type, mutation characteristics, management for metastatic disease, progression free survival, number of CNS metastases, and location of metastatic disease were assessed. Inclusion criteria were age&gt;18 years, diagnosis of primary ovarian, uterine, or cervical cancer with confirmed metastatic disease to the CNS, including brain parenchyma, leptomeninges, or intradural spinal cord or dural metastases. Exclusion criteria included pediatric population and bony metastases (e.g., bony spine metastases without evidence of meningeal/parenchymal invasion). Results Our review showed that patients with gynecological metastasis to the CNS generally have worse outcomes regarding overall survival, progression free survival, and quality of life than patients without CNS metastasis. Discussion Our results infer that the reported increase in incidence of CNS metastasis from gynecologic malignancies is a reflection of improvement of detection given advances in technology, improved patient follow up, and increased overall survival of patients with gynecologic malignancies. Further characterization of mutations from gynecologic malignancies associated with brain metastasis could result in development of more treatment options for patients in the future and help determine factors that contribute to developing metastasis to the CNS of various degrees, thus, potentially inform treatment strategies.

441 Background: Gemcitabine and nab-paclitaxel has been reported to prolong survival in patients with metastatic pancreatic cancer. This drug combination was studied in such patients in the MPACT trial with an average age of enrolled patients being 63. Pancreatic cancer, however, is a disease of the aging with a median age at diagnosis of 70. Reductions in dosing by 20% or more in one or both components and has been shown to improve the tolerability of this regimen, thereby increasing treatment exposure. Our study aims to examine the efficacy and tolerability of this drug combination in an elderly population and how this is affected by schedule and dosing modifications. Methods: A retrospective chart review was performed of 83 patients over the age of 70 with a median age of 79 who received this drug combination as first-line treatment for pancreatic adenocarcinoma at a single institution. Overall survival and progression-free survival were assessed as well as schedule modification, dose reduction, and rates of adverse events. Results: For patients with metastatic or non-metastatic disease, the mean overall survival and progression-free survival were found to be 10.57 months and 6.63 months, respectively. When only patients with metastatic disease are analyzed, these values were found to be 9.26 months and 6.05 months, respectively, which are similar to those observed in the MPACT trial. The most common adverse events of grade 3 or greater were fatigue in 34.9% of patients and hematologic adverse events including neutropenia in 27.7% and leukopenia in 25.3% of patients. Dose reductions were commonly used to mitigate adverse events. Reductions in either one or both drugs by at least 20% occurred in 84.3% of patients. Conclusions: Gemcitabine and nab-paclitaxel in treatment of pancreatic cancer is well tolerated in an elderly population with similar rates of adverse effects when compared with previous studies, though this population experienced a significantly higher rate of fatigue. Dose reductions were used frequently in this population to improve tolerability, which may have contributed to the observed increase in overall survival in this population.

HypothesisWe hypothesize that adjuvant radiation and chemotherapy improve the clinical benefit from treatment of advanced-stage endometrial adenocarcinoma.MethodsWe conducted a retrospective review of 125 patient with stage III or IVA endometrial adenocarcinoma who received adjuvant chemotherapy (n = 60) or chemoradiation (n = 65). Primary end points were rate of clinical benefit (ie, the percentage of patients who were alive and disease-free for at least 6 months after the last day of adjuvant treatment) and progression-free and overall survival.ResultsThe addition of radiation to chemotherapy improved the rate of clinical benefit from 55% to 77%. Differences in clinical benefit were attributed to a reduction in the number of pelvic relapses after chemoradiation. There were no substantial differences in the rate of extrapelvic relapse events seen between the chemotherapy alone and chemoradiation groups. Patients receiving radiation had prolonged median progression-free survival (36 vs 17 months in chemotherapy alone) and median overall survival (70 vs 64 months in chemotherapy alone).ConclusionsThe addition of radiation to chemotherapy improved the clinical benefit of patients with stage III or IVA endometrial adenocarcinoma. A clinical trial powered to evaluate clinical benefit and survival outcomes of chemotherapy and radiation is under way.

Abstract Introduction There is a paucity of data on platinum-based chemotherapy in advanced breast cancer (ABC) from developing countries like India. Objectives The objectives were to analyze the efficacy and safety of platinum-based chemotherapy in patients with ABC. Materials and Methods This was a retrospective study of 35 patients with ABC who were treated with platinum-based chemotherapy (gemcitabine and carboplatin, [GC]) in a tertiary cancer center in India from August 2015 to November 2019. The inclusion criteria were patients with ABC, who had received palliative chemotherapy with GC. The exclusion criteria were patients who had received less than two cycles of GC and patients who received platinum-based chemotherapy for neuroendocrine carcinoma of the breast. Results The median age was 45 years (range: 28–68 years). All patients were female (97%) except one male (3%). The histology was ductal carcinoma (77%), mixed (17%), and others (6%). Out of the 12 patients tested for breast cancer (BRCA) gene mutation, six patients had a BRCA mutation. Patients with metastatic and locally progressive disease were 91 and 9%, respectively. The median number of prior lines of systemic therapy for metastatic disease was 1 (range: 0–5). The median number of sites of metastasis was 2 (range: 0–5). Patients with visceral crises were 23%. The median number of cycles of GC chemotherapy received was 6 (range: 2–6). A dose reduction in chemotherapy was done in 74%. The responses among 34 evaluable patients were complete response (11%), partial response (24%), stable disease (41%), and progressive disease (24%). Grade 3 or more hematological and nonhematological toxicities were observed in 69 and 9%, respectively. The median progression-free survival and overall survival were 6 and 8 months, respectively. The 1-year progression-free survival and overall survival were 19 and 34%, respectively. Multivariate analysis showed that patients who had received more than 3 cycles had a better outcome. Conclusion GC was an active and well-tolerated regimen in ABC regardless of the receptor status. Further prospective randomized studies are warranted to assess the optimal regimen in patients with triple-negative breast cancer.

e23511 Background: Conditional survival provides a dynamic prediction of prognosis for patients surviving a defined period of time after diagnosis. This study aimed to determine the conditional survival and prognostic factors over time among patients with non-metastatic bone osteosarcoma. Methods: We reviewed 714 bone osteosarcoma patients treated from 1985 to 2016. Patients with metastatic disease at diagnosis or limited follow up were excluded, resulting in 587 cases for analysis. Clinical and pathological variables were recorded. Predictive variables included age at diagnosis, gender, previous radiation history, tumor site, tumor size, histologic subtype, histologic grade, resection margin, chemotherapy, and radiation therapy. The multivariate Cox proportional hazards regression was used to analyze prognostic factors of conditional overall survival and progression-free survival at baseline and 5 years after diagnosis. Results: The estimated 5-year conditional overall survival increased from 71.0% (95% CI: 67.5%-75.0%) at baseline to 86.9% (95% CI: 82.6%-90.5%) at 5 years, which means if a patient with non-metastatic bone osteosarcoma survived 5 years, the chance of surviving another 5 years was 86.9%. If the patient was progression-free for 5 years, the 5-year conditional overall survival was even higher, 93.2% (95% CI: 89.5%-96.4%), and the 5-year conditional progression-free survival improved from 57.1% (95% CI: 53.3%-61.0%) at baseline to 91.2% (95% CI: 87.5%-94.6%) at 5 years. Prognostic factors for mortality and disease progression change as survival time increases. At baseline, age (p < 0.001 and p = 0.003), histologic subtype (p < 0.001 and p = 0.001), grade (p < 0.001 and p < 0.001), tumor size (p = 0.002 and p = 0.002), resection margin (p < 0.001 and p < 0.001) and chemotherapy (p = 0.001 and p = 0.001) were predictive of both overall survival and progression-free survival. However, only age (p < 0.001) and histologic subtype (p = 0.015) remained significant for mortality and resection margin (p = 0.001) for disease progression at 5 years. Conclusions: The survival probability of osteosarcoma improves as survival time increases. Estimates of conditional survival can provide useful information for individualized surveillance strategies, risk evaluation, patient counseling, and making clinical decisions.

e20001 Background: Multiple Myeloma (MM) is a neoplasm of the post-germinal center, terminally differentiated B-cells. MM accounts for 1% of all types of cancer and 10% for all hematologic malignancies. Chronic hepatitis C virus (HCV) is an infection that affects over 71 million patients worldwide. Cytotoxic agents and immunosuppressive therapy as steroids are the main line of therapy in lymphoid malignancies, but these drugs may exacerbate chronic viral hepatitis and cause uncontrolled replication of hepatitis viruses. The impact of HCV infection on MM patients remains unclear. Objective: To assess the impact of HCV infection on the prognosis and management of MM patients. Methods: A 10-year retrospective study of MM patients was conducted at Cairo University Clinical Oncology Department from January 2009 to April 2019. Results: During this time, 150 patients were diagnosed with MM, 109 (72.7%) were HCV negative, 24 (16%) were HCV positive, and 17 (11.3%) with unknown HCV status. The median age was 51 and 54 years for HCV negative and positive groups respectively, with a statistically insignificant difference (p-value > 0.2). In the multivariate analysis, HCV infection was not an independent factor related to overall survival (OS), however age, creatinine and hemoglobin levels correlated significantly with OS (p < 0.009, 0.008, 0.031 respectively). The median OS for the HCV negative group was 31.11 months (95% CI: 22.62 - 39.61) compared to 37.66 months (95% CI: 7.19 - 68.13) for the HCV positive group. The median progression-free survival (PFS) for all patients was 18.9 months, for HCV positive patients was 15.36 months (95% CI: 13.18 – 17.54), and for HCV negative patients was 20.49 months (95% CI: 14.13 – 26.85). Age below 60 years and creatinine level less than 2 mg/dL were statistically significant for favorable disease-free survival (DFS) (p < 0.030, 0.034 respectively). Conclusions: Age, creatinine and hemoglobin levels are significant prognostic factors in MM but HCV status doesn’t affect the overall survival or progression-free survival. HCV infection should not contraindicate MM therapy.

Objective: To compare the effectiveness, safety and survival outcome of transcatheter arterial chemoembolization (TACE) combined with high-intensity focused ultrasound (HIFU) versus surgical resection for treating single hepatocellular carcinoma (HCC) with Child-Pugh B cirrhosis. Methods: A hospital-based retrospective study with 146 patients diagnosed with single HCC with Child-Pugh B cirrhosis from July 2010 to July 2018 was conducted in a tertiary teaching hospital. A total of 49 patients underwent TACE combined with HIFU (the combined group), and 97 patients underwent surgical resection (the resection group). Of them, 22 patients undergoing TACE combined with HIFU and 45 patients undergoing surgical resection had small HCC (tumor diameter ≤3 cm). The overall survival (OS) time, progression-free survival (PFS) time and postoperative complications were compared between the two groups. Results: In the single HCC tumor cohort, there was no significant difference in OS between the two groups [hazard ratio (HR) = 0.6379; 95% confidence interval (95% CI) = 0.3737 to 1.089; P = .0995], while the resection group showed an obvious superiority to the combined group regarding PFS (HR = 0.3545; 95% CI = 0.2176-0.5775; P < .0001). The 1-year, 3-year and 5-year recurrence rates were 30.9%, 55.7%, 86.6% in the resection group and 53.1%, 77.6%, 89.8% in the combined group, respectively. In the small HCC tumor cohort, there was also no difference in OS between the two groups (HR = 0.8808; 95% CI = 0.3295-2.355; P = .06396), while the resection group showed an obvious superiority to the combined group regarding PFS (HR = 0.4273; 95% CI = 0.1927-0.9473; P = .0363). The 1-year, 3-year and 5-year recurrence rates were 28.9%, 53.3%, 93.3% in the resection group and 40.9%, 68.2%, 81.8% in the combined group, respectively. Furthermore, the incidence of complications of the combined group was 38.8%, which was significantly less than the 56.7% of the resection group ( P = .041), and the duration of general anesthesia in the combined group was shorter than that in the resection group ( P = .001). Therein, there was no difference in the incidence of grade I complications (Clavien-Dindo classification) between the two groups ( P = .866). Conclusion: For patients with single or single small HCCs, TACE combined with HIFU may not be inferior to surgical resection in terms of the long-term survival rate, while surgical resection still has a definite advantage in terms of delaying recurrence. In addition, the combination of TACE and HIFU has higher safety than surgical resection.

Object Optimal treatment of primary and recurrent craniopharyngiomas remains controversial. Radical resection and limited resection plus radiation therapy yield similar rates of disease control and overall survival. The data are much less clear for recurrent tumors. The authors report their experience with radical resection of both primary and recurrent craniopharyngiomas in children and compare the outcomes between the 2 groups. Methods A retrospective analysis was performed in 86 children younger than 21 years of age who underwent a total of 103 operations for craniopharyngioma between 1986 and 2008; these were performed by the senior author. The goal was resection with curative intent in all patients. Two patients were lost to follow-up and were excluded from analysis. The mean age at the time of surgery was 9.6 years, and the mean follow-up was 9.0 years. Results All 57 children with primary tumors underwent gross-total resection (GTR). A GTR was achieved in significantly fewer children with recurrent tumors (18 [62%] of 29). There were 3 perioperative deaths (3%). Tumor recurred after GTR in 14 (20%) of 71 patients. Overall survival and progression-free survival were significantly better in patients with primary tumors at time of presentation to the authors' institution. There were no significant differences in the neurological, endocrinological, visual, or functional outcomes between patients with primary and those with recurrent tumors. Factors negatively affecting overall survival and progression-free survival include subtotal resection (recurrent tumors only), tumor size ≥ 5 cm, or presence of hydrocephalus or a ventriculoperitoneal shunt. Prior radiation therapy and increasing tumor size were both risk factors for incomplete resection at reoperation. Conclusions In the hands of surgeons with experience with craniopharyngiomas, the authors believe that radical resection at presentation offers the best chance of disease control and potential cure with acceptable morbidity. While GTR does not preclude recurrence and is more difficult to achieve in recurrent tumors, especially large and previously irradiated tumors, radical resection is still possible in patients with recurrent craniopharyngiomas with morbidity similar to that of primary tumors.

Purpose Soft tissue sarcomas are associated with a poor prognosis and low chemotherapeutic efficiency. Pazopanib is an orally available multi-tyrosine kinase inhibitor that was explored in patients with non-adipocytic advanced soft tissue sarcomas. The aim of this retrospective study was to evaluate the real life data of single-agent pazopanib efficacy and safety for soft tissue sarcomas in the Turkish population. Materials and methods We evaluated a total of 103 patients (41 males, 62 females) who received pazopanib for advanced non-adipocytic soft tissue sarcomas diagnosis in eight centers of Turkey, retrospectively. The pazopanib dose was 800 mg once daily. Progression-free survival, overall survival, and adverse events were analyzed. Results The median age was 50 years (range, 38–58). Majority of the patients had leimyosarcoma (41%). Median progression-free survival was 4.3 months, and the median overall survival was 10.1 months. The main common toxicities were fatigue, anorexia, weight loss, nausea, hypertension, and grade ≥3 toxicities were fatigue, anorexia, weight loss, and liver disorder. Conclusion Pazopanib is an efficient and tolerable agent and is well tolerated in good performance status patients with relapsed, advanced non-adipocytic soft tissue sarcomas.

Abstract Background Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer. Globally, liver cancer is the 5th and 7th most common cancer in men and women, respectively. Most of HCC burden lies in developing countries. The regions of high incidence include Eastern and South-Eastern Asia, Middle and Western Africa. Worldwide, it is the third most common cause of cancer deaths Aim of the Work A retrospective study of Hepatocellular carcinoma patients presented to Ain Shams University Hospital clinical oncology department between the period of 1/2013 till the end of 12/2016 aiming to review of epidemiological and clinical risk factors, response to the therapy used, progression free survival and overall survival. Patients and Methods The current study is a retrospective analysis carried out in Ain-Shams clinical Oncology and Nuclear Medicine department, Faculty of medicine, Ain Shams University between the period of 1st January 2013 till the end of 2016, where 136 medical records were planned to be analyzed, from which 18 records were not included in analysis (8 records weren’t available in the archive, 10 contained inadequate data) and 118 were analyzed aiming at detection of the prognostic factors, response, progression free survival and overall survival of patients with HCC. Results Regarding age, the median age at diagnosis was 58 years (SD = 8.29), where the average median age was 57.5 years. In our study most of patients were presented with good PS, where 100 (84.7%) of them had performance status less than or equals 2 and only 18 patients (11.8%) were more than or equals 3 performance status &lt; 2 in 84 % of all cases and &gt;2 in 16 %. Conclusion To conclude, age as a prognostic factor significantly affects survival in favor of patients &lt; =58 years. RFA affects survival. Performance status significantly affects survival. The quality of data reported was to some extent impaired due unavailability of complete clinical, analytical and radiological information in the charts.
