The objective: was to determine the impact of androgen receptor (AR) expression on the effectiveness of the first and second line chemotherapy in patients with metastatic triple negative breast cancer (mTNBC). Materials and methods. The impact of AR expression on treatment results was evaluated in patients with mTNBC received the first (n=122) and second (n=87) line chemotherapy in open randomized studies. The status of AR was evaluated by immunohistochemistry, AR positive patients were defined as having AR more than 10%. Results. From 116 patients with mTBNC 44 (38%) were AR positive, 72 (62%) – AR negative. Median progression free survival in patients received the first line chemotherapy was 8 months in AR positive and 6 months in AR negative, p=0.27. The incidence of objective tumor response in mTNBC patients received the second line chemotherapy was 71.1% in AR negative and 76.92% in AR positive, p=0.48. Median progression free survival in patients received the second line chemotherapy was 6 months in AR positive and 4 months in AR negative, p=0.0045. Median overall survival in AR positive patients was statistically significantly higher (12 months versus 9 months, р=0.04). Conclusions. Impact of AR expression on progression free and overall survival was proved for mTNBC patients received the second line chemotherapy. Keywords: metastatic triple negative breast cancer, androgen receptor, chemotherapy, progression free survival, overall survival.

The objective: was to evaluate the efficacy of the first line chemotherapy in patients with metastatic triple negative breast cancer (TNBC). Materials and methods. Open randomized study was performed including 122 patients with metastatic TNBC. The efficacy and safety of the first line chemotherapy of regimens АТ (n=59) – group 1, patients received doxorubicine 60 мг/м2 and paclitaxel 175 мг/м2 and ТР (n=63) – group 2, patients received paclitaxel 175 мг/м2 and carboplatin AUC 5 were evaluated. Results. The median duration of response was 9.5 months (4.5–13.25 months) in patients received AT regimen and 8.5 months (4.7–12.25 months), in TP regimen; no statistically significant differences were observed, р=0.836. The median progression free survival was 7 months (95% CI 5–26 months) in group 1 and 7.5 months (95% CI 6–35 months) in group 2, p=0.85. Both chemotherapy regimens (AT and TP) had mild or moderate toxicity profiles (grade 1 or 2 in most patients). No significant difference in gastrointestinal toxicity was observed. The incidence of grade 3–4 neutropenia was higher in patients of group 2 (TP regimen): 42.8% versus 27% (р<0.05). Conclusions. Both regimens of chemotherapy (AT and TP) are appropriate to use in the first line setting in patients with metastatic TNBC. Key words: metastatic triple negative breast cancer, chemotherapy, progression free survival, chemotherapy toxicity.

5151 Background: There is currently no standard of care for patients (pts) with HRPC and disease progression after docetaxel-based chemotherapy. Platin compounds have demonstrated activity in this setting and in vitro evidence of synergy between carboplatin and etoposide has previously been reported. A significant proportion of advanced HRPC exhibit neuroendocrine features but there are limited data on whether these patients should be treated differently or not. Methods: Pts with HRPC who experienced failure after first-line docetaxel-based chemotherapy were prospectively treated with carboplatin (AUC 5 day 1) and etoposide (80 mg/m2 day 1 to 3), repeated every 3 weeks as second-line chemotherapy. The response rate (defined as a serum PSA decline of = 50%), progression-free survival (PFS) and overall survival (OS) were evaluated using consensus criteria (Bubley JCO 1999). Pain relief was evaluated using a visual analogic scale. Serum chromogranin A and neurone specific enolase (NSE) levels were measured at baseline. Toxicity was evaluated according to NCI criteria. Results: Forty-one HRPC pts, previously treated with docetaxel with (n=24) or without (n=17) estramustine, prospectively received carboplatin-etoposide as second-line chemotherapy. A PSA response was obtained in 9 pts (22%). Pain relief was achieved in 18 pts (45%). Median progression-free survival was 9 weeks and median overall survival was 19 months. Toxicity included grade 3–4 anemia in 25% and febrile neutropenia in 2%. Biological neuroendocrine features (e.g. elevated baseline serum chromogranin A and NSE) were not associated with response or PFS. The response rate was 18% and 31% in pts with normal and elevated baseline chromogranin A, respectively. Conclusions: The carboplatin-etoposide regimen is active and well-tolerated as second-line chemotherapy after docetaxel-based chemotherapy in HRPC patients. Activity was detected in both tumors with and without neuroendocrine features. No significant financial relationships to disclose.

450 Background: The standard treatment for patients with gallbladder cancer is a combination of gemcitabine and cisplatin based on ABC-02 trial. However, there are no guidelines regarding treatment after first-line therapy. We retrospectively analyzed the efficacy and overall survival of different second-line regimens. Methods: We identified 203 patients with advanced gallbladder cancer who received palliative treatment between January 2000 and December 2015 at Mayo Clinic, Rochester. RECIST criteria was used to assess response. Results: 68 patients received second-line chemotherapy. Median age was 63 years (range: 32-86) and majority were males (60.6%). The median time from the diagnosis to the start of the second line chemotherapy was 8 (1-120) months. The most common used second-line chemotherapy were FOLFOX (14), gemcitabine alone (10), single agent fluoropyrimidine (11), gemcitabine with capecitabine (5), and capecitabine with oxaliplatin (4). There were 30 patients that received 5-fluorouracil based regimens, 20 patients received gemcitabine-based regimen, 3 patients received taxane-based regimen, and 15 patients received other types of chemotherapy. Median progression free survival and overall survival was 2.1 (1.8-2.7) and 16.7 (13.2-21.3) months respectively. There were 10 (52%), 11 (37%), 2 (67%), 5 (33%) with partial response and stable disease in 5-fluorouracil-based, gemcitabine-based, taxane-based, and others, respectively. There were no difference in PFS, with median PFS of 2.5, 2.0, 2.8 and 2.3 months, respectively (p=0.43). The overall survival were 15.7 (8.9-40.2), 15.0 (10.7-21.3), 40.3 (22.0-47.0), and 20.4 (9.2-30.7) months, respectively (p=0.83). There were 27 patients that received single agent chemotherapy and 41 patients that received combined regimen. There were 17 (42%) patients and 13 (48%) patients with partial response or stable disease in single and combined regimen. There were no differences in progression free survival and overall survival between single and multi agent chemotherapy. Conclusions: In this largest single institution study, second-line chemotherapy regimens for gallbladder cancer provided benefit in select patients and there is an urgent need to develop more active therapeutic regimens.

e17019 Background: Based on our previous study, the systemic immune-inflammation index (SII) is a prognostic factor in patients with metastatic urothelial cancer (MUC) treated with platinum-based first-line chemotherapy. The objective of this retrospective analysis was to explore prognostic value of the SII at baseline of second-line chemotherapy with vinflunine in MUC population. Methods: We evaluated 70 consecutive MUC (53 bladder, 21 upper tract) patients (54 men) treated with second-line chemotherapy with vinflunine at four oncological departments since 2010. ECOG performance status (PS) ≤ 1 had 44 patients (pts.), haemoglobin < 10 g/dL was present in 25 pts. and liver involvement in 18 pts. SII was based on platelets (P), neutrophils (N) and lymphocytes (L) counts defined as PxN/L. This study population was dichotomized by median into low SII and high SII groups. Progression-free survival (PFS), overall survival (OS) and their 95% CI were estimated by Kaplan-Meier method and compared with logrank test. Results: At median follow-up of 9.0 months (1-29 months), 68 pts. experienced disease progression and 62 died. Pts. with low SII at baseline had significantly better PFS and OS opposite to those with high SII (HR = 0.61, 95% CI 0.37-1.00, p = 0.0318 for PFS, HR = 0.60, 95% CI 0.36-1.00, p = 0.0312 for OS, respectively). In addition to the prognostic factors by Bellmunt (ECOG PS ≥ 1, liver involvement, haemoglobin < 10 g/dL), we identified peritoneal metastases as a factor associated with significantly worse survival (HR = 0.28, 95% CI 0.11-0.72, p < 0.00001 for PFS, HR = 0.30, 95% CI 0.12-0.75, p < 0.00001 for OS, respectively). Conclusions: The SII at baseline of treatment with second-line vinflunine represents a prognostic factor for pts. with MUC. Based on SII, pts. could be stratified into clinical trials in future. MUC pts. with high SII might be candidates for a different treatment approach. Key Words: Metastatic Urothelial Carcinoma. Systemic Immune-Inflammation Index. Vinflunine. Progression-Free Survival.

Purpose Studies suggest that a subset of patients with triple-negative breast cancer (TNBC) have tumors that express the androgen receptor (AR) and may benefit from an AR inhibitor. This phase II study evaluated the antitumor activity and safety of enzalutamide in patients with locally advanced or metastatic AR-positive TNBC. Patients and Methods Tumors were tested for AR with an immunohistochemistry assay optimized for breast cancer; nuclear AR staining > 0% was considered positive. Patients received enzalutamide 160 mg once per day until disease progression. The primary end point was clinical benefit rate (CBR) at 16 weeks. Secondary end points included CBR at 24 weeks, progression-free survival, and safety. End points were analyzed in all enrolled patients (the intent-to-treat [ITT] population) and in patients with one or more postbaseline assessment whose tumor expressed ≥ 10% nuclear AR (the evaluable subgroup). Results Of 118 patients enrolled, 78 were evaluable. CBR at 16 weeks was 25% (95% CI, 17% to 33%) in the ITT population and 33% (95% CI, 23% to 45%) in the evaluable subgroup. Median progression-free survival was 2.9 months (95% CI, 1.9 to 3.7 months) in the ITT population and 3.3 months (95% CI, 1.9 to 4.1 months) in the evaluable subgroup. Median overall survival was 12.7 months (95% CI, 8.5 months to not yet reached) in the ITT population and 17.6 months (95% CI, 11.6 months to not yet reached) in the evaluable subgroup. Fatigue was the only treatment-related grade 3 or higher adverse event with an incidence of > 2%. Conclusion Enzalutamide demonstrated clinical activity and was well tolerated in patients with advanced AR-positive TNBC. Adverse events related to enzalutamide were consistent with its known safety profile. This study supports additional development of enzalutamide in advanced TNBC.

Abstract Background Standard treatment for malignant peritoneal mesothelioma has not been established, and systemic chemotherapy is administered according to malignant pleural mesothelioma. We previously reported the efficacy of cisplatin plus pemetrexed as first-line chemotherapy; however, the efficacy of second-line chemotherapy remains unknown. Methods We retrospectively evaluated patients with malignant peritoneal mesothelioma who started first-line systemic chemotherapy with platinum plus pemetrexed between March 2007 and February 2019 at the National Cancer Center Hospital. Patients who received second-line chemotherapy after failure of platinum plus pemetrexed were identified. We evaluated the efficacy of first- and second-line chemotherapy, and explored the prognostic factors. Survival outcomes were estimated using the Kaplan–Meier method, and between-group differences were compared using the log-rank test. Univariate and multivariate analyses were performed using Cox proportional hazards models. Results A total of 54 and 26 patients received platinum plus pemetrexed as first- and second-line chemotherapy, respectively (gemcitabine in 12 patients; taxane, six; nivolumab, three; and others, five). In all patients, the median overall survival and progression-free survival after first-line chemotherapy were 16.6 and 7.3 months, respectively. Among patients who received second-line chemotherapy, the median overall survival, progression-free survival, and second-line overall survival were 16.9, 3.2, and 9.9 months, respectively. Patients who received ≥6 cycles of platinum plus pemetrexed as first-line chemotherapy had longer overall survival after second-line chemotherapy than those who did not (hazard ratio, 0.23; 95% confidence interval: 0.06–0.82; p = 0.02). Conclusions Second-line chemotherapy may be an option for refractory malignant peritoneal mesothelioma, especially in patients who have completed 6 cycles of platinum plus pemetrexed as first-line chemotherapy.

Background. Treatment results for the patients with stage II–III triple negative breast cancer (TN BC) have to be improved. Not only the new treatment regimens, but new predictive and prognostic factors should to be developed.Materials and methods. We included 98 patients with stage II–III TN BC in our study. We studied efficacy and safety of PlaTax regimen (cisplatin 75 mg / m2 day 1 + paclitaxel 80 mg / m2 days 1, 8, 15, course every 4 weeks) in this cohort of patients. We assessed pathologic response, survival and factors, which were relevant for predicting response and prognose survival.Results. PlaTax regimen is characterized by high efficacy and tolerable toxicity. Clinical efficacy was 85.8 %, pCR achievement was 60.5 %, tpCR achievement was 58.1 %. The regimen has low haematological toxicity (neutropenia III–IV grades – 4.1 %); the most frequent adverse events were polyneuropathy (18.5 %) and decreased renal function (24.5 %). 3-year progression-free survival was 68.4 %, most of the relapses (92 %) occurred during first 2 years. 3 year overall survival was 77.6 %. The most relevant predictive factor was level of Ki-67 ≥50 % (pCR 38.5 % vs. 68.7 %, p = 0.038). pCR achievement was the most important prognostic factor, resulting in improved 3-year progressionfree survival (44.3 % vs. 89.1 %, p <0.0001), and 3-year overall survival (61.5 % vs. 91.6 %, p = 0.001). Not only the residual disease, but also the size of residual tumor was important from prognostic point of view. Other important prognostic factors were size of the tumor, status of regional lymph nodes, grade. Delay in surgical treatment more than a month lead to decreased 3-year progression-free survival: 87.1 % vs. 62.5 % (p = 0.047).Conclusions. Our data suggest that studied regimen could be an option for patients with stage II–III TN BC. The assessment of the predictive and prognostic factors will help improve the treatment results for patients with stage II–III TN BC.
