Purpose. This study retrospectively evaluated overall survival (OS) by treatment of recurrent or metastatic uterine adenosarcoma including surgery, radiation, chemotherapy, and hormonal therapy and evaluated OS and progression-free survival (PFS) after 1st line systemic chemotherapy. Methods. 78 patients with recurrent or metastatic adenosarcoma comprised the study population. The Kaplan-Meier method was used to estimate OS and PFS. The log-rank test was performed to test the difference in survival between groups. Results. Median OS from diagnosis of recurrent or metastatic disease was 1.8 yrs. OS was influenced by pathology on recurrence, p=0.035. Median OS differed by surgery for 1st recurrence 26.3 months versus 15.1 months. OS was not influenced by chemotherapy, p=0.58, palliative radiation, p=0.58, or hormonal therapy, p=0.15. The response rate (CR + PR) per RECIST 1.1 for chemotherapy was 31.2% for doxorubicin-based regimens and 14.3% for gemcitabine/docetaxel. OS since 1st line chemotherapy was not significantly different among chemotherapy regimens. However, the median PFS was superior for doxorubicin/ifosfamide (15.4 months) compared to gemcitabine/docetaxel (5.0 months), platinum-based regimens (5.7 mo), or other doxorubicin-based regimens (6.5 months). Conclusion. These results suggest that surgery is an important treatment modality for recurrent or metastatic uterine adenosarcoma, and the most effective chemotherapeutics are doxorubicin/ifosfamide and gemcitabine/docetaxel.

Number Of Cycles

e18125 Background: Platinum based regimens are standard first-line treatment in patients with advanced non mall cell lung cancer. We intend to evaluate their effectiveness according to the number of cycles administered, and investigate whether histology is a predictor of benefit from a greater number of infusions. Methods: 124 patients with stage IV NSCLC were evaluated retrospectively. They were divided according to whether they made 4 or 6 cycles of chemotherapy. The schemes used were: Cisplatin / Gemcitabine and Carboplatin / Paclitaxel, at standard doses. We studied the efficacy in both groups according to the most common histologies (adenocarcinoma and squamous cell carcinoma). PFS (progression-free survival) and OS (overall survival) were calculated by the Kaplan-Meier curves and compared by the Log Rank Test. Results: Those who underwent 4 cycles had a PFS of 7.77 months and OS of 12.2 months vs. 8.64 and 10.8 months those who received 6 cycles (p = 0.47, p = 0.76). Within the subgroup with squamous histology (n = 43), PFS and OS were 7.38 and 13.38 months respectively in the group that received 4 cycles vs. 7.97 and 9.76 months in those receiving 6 (p = 0.70, p = 0.32 ). Within adenocarcinoma histology (n = 81), those who received 4 cycle, has a PFS of 8.17 months and they lived 11.56 month, vs 8.96 and 10.79 months for those receiving 6 cycles (p = 0.29, p = 0.88) Conclusions: In our population, a greater number of cycles showed no advantages in terms of progression-free survival or overall survival. Histology is not a predictive factor for deciding how many chemotherapy cycles administer.

Purpose The primary objective of this study was to determine whether carboplatin, paclitaxel, and sorafenib (CPS) improve overall survival (OS) compared with carboplatin and paclitaxel (CP) in chemotherapy-naive patients with metastatic melanoma. Patients and Methods In this double-blind, randomized, placebo-controlled phase III study, all patients received carboplatin at area under the [concentration-time] curve 6 and paclitaxel 225 mg/m2 intravenously once every 21 days with random assignment to sorafenib 400 mg orally twice per day on days 2 through 19 every 21 days or placebo. The primary end point was OS, and secondary end points included progression-free survival, objective tumor response, and toxicity. Results In all, 823 patients were enrolled over 34 months. At final analysis, the median OS was 11.3 months (95% CI, 9.8 to 12.2 months) for CP and 11.1 months (95% CI, 10.3 to 12.3 months) for CPS; the difference in the OS distribution was not statistically significant by the stratified log-rank test, stratified on American Joint Committee on Cancer (AJCC) stage, Eastern Cooperative Oncology Group (ECOG) performance status, and prior therapy (P = .878). Median progression-free survival was 4.9 months for CPS and 4.2 months for CP (P = .092, stratified log-rank test). Response rate was 20% for CPS and 18% for CP (P = .427). More patients on the CPS arm had grade 3 or higher toxicities (84% v 78%; P = .027), with increased rash, hand-foot syndrome, and thrombocytopenia accounting for most of the difference. Conclusion Sorafenib does not improve OS when given in combination with CP for chemotherapy-naive patients with metastatic melanoma. This study establishes benchmark end points for the CP regimen in first-line therapy of metastatic melanoma.

Introduction The five-year survival rate for patients with glioblastoma (GBM) is low at approximately 4.7%. Radiotherapy plus concomitant and adjuvant temozolomide (TMZ) remains the standard of care. The optimal duration of therapy with TMZ is unknown. This study sought to evaluate the survival benefit of two years of treatment. Methods This was a retrospective chart review of all patients diagnosed with GBM and treated with TMZ for up to two years between January 1, 2002 and December 31, 2011. The Kaplan-Meier method with log-rank test was used to estimate the progression-free survival (PFS) and the overall survival (OS). The results were compared to historical controls and data from previous clinical trials of patients treated up to one year. Results Data from 56 patients with confirmed GBM were evaluated. The OS probability was 54% (SE = 0.068) at one year, 28.3% (SE = 0.064) at two years, 17.8% (SE = 0.059) at three years, and 4% (SE = 0.041) at five years. Seven patients (12.5%) were treated with TMZ for two years. Their median time-to-progression was 28 months (95% CI = 5.0 - 28.0), and they had an increased survival probability at three years compared to other patients (log-rank test χ2 (1, N = 56) = 19.2, p < 0.0001). Conclusions There may be an advantage for a longer duration of TMZ therapy among patients with GBM, but the sample size was too small for generalization. A multicenter prospective study is needed to dentify optimal duration of TMZ therapy.

Background: We investigated the response rate and degree of toxicity of a second course of three cycles of [177Lu]Lu-PSMA radioligand therapy (PSMA-RLT) every 4 weeks in mCRPC patients. Methods: Forty-three men (71.5 ± 6.6 years, median PSA 40.8 (0.87–1358 µg/L)) were studied. The response was based on the PSA level 4 weeks after the third cycle. The laboratory parameters before and one month after the last cycle were compared. Kaplan–Meier methods were used to estimate the progression-free survival (PFS) and overall survival (OS), and the Cox regression model was performed to find predictors of survival. Results: Twenty-six patients (60.5%) exhibited a PSA reduction (median PSA declined from 40.8 to 20.2, range 0.6–1926 µg/L, p = 0.002); 18 (42%) and 8 (19%) patients showed a PSA decline of ≥50% and ≥80%, respectively. The median OS and PFS were 136 and 31 weeks, respectively. The patients with only lymph node metastases survived longer (p = 0.02), whereas the patients with bone metastases had a shorter survival (p = 0.03). In the multivariate analysis, only the levels of PSA prior to the therapy remained significant for OS (p < 0.05, hazard ratio 2.43, 95% CI 1.01–5.87). The levels of hemoglobin (11.5 ± 1.7 g/dL vs. 11 ± 1.6 g/dL, p = 0.006) and platelets (208 ± 63 g/L vs. 185 ± 63 g/L, p = 0.002) significantly decreased one month after cycle three, though only two grade 3 anemia and one grade 3 thrombocytopenia were recorded. Conclusion: A further intensive PSMA-RLT course is well tolerated in mCRPC patients and associated with promising response rates and OS.

e21032 Background: Previous studies suggested that MET exon 14 ( METex14) mutation regarding as a distinct subset was sensitive to MET-inhibitors, but poorly response to immunotherapy. Conversly, MET non-exon-14 (non-ex14) mutations including those undetermined functions and affecting the kinase or extracellular domains were found to be associated with the resistance to MET-inhibitors. However, therapeutic strategies for MET-non-ex14 mutant cancer are still largely unknown, and the relationship between MET-non-ex14 mutations and the efficacy of immune checkpoint inhibitors (ICIs) has never been reported. Using two public ICIs-treated cohorts, we aimed to assess the role of MET mutations including both METex14 and MET-non-ex14 mutations in NSCLC patients undergoing ICIs therapy. Methods: A total of 385 ICIs-treated NSCLC patients were enrolled to our study. MET mutations were defined as any nonsynonymous mutations, and we divided them into METex14 and MET-non-ex14 mutation subsets according to the mutated-position on MET. Kruskal-Wallis test was used to analyze the difference of tumor mutational burden (TMB) score, and the Fisher’s exact test was applied to compare the rates of durable clinical benefit (DCB). Log-rank test was used to analyze the differences between Kaplan-Meier survival curves. Results: In the entire cohort, we found that 17 patients (17/385, 4.4%) had MET mutations, most of which were pure METex14 mutations (10/17, 58.8%). The median TMB of patients in the entire NSCLC cohort was 6.89 mut/Mb. MET-non-ex14 mutant patients (7/385, 1.8%) possessed a significantly higher TMB than METex14-mutant (10/385, 2.6%) and MET wild-type (368/385, 95.6%) sub-cohorts, respectively (median TMB, 17.92 mut/Mb versus 4.17 mut/Mb, p = 0.008; 17.92 mut/Mb versus 6.96 mut/Mb, p = 0.01, respectively). DCB was more common in patients harbored MET-non-ex14 mutations than patients with METex14 mutations and MET wild-type (66.7% versus 14.3%, p = 0.103; 66.7% versus 29.9%, p = 0.075, respectively). We found that patients with MET-non-ex14 mutations had a numerically longer progression free survival (PFS) than those with METex14 mutations and MET wild-type (p = 0.169). Moreover, the PFS was significantly longer in MET-non-ex14-mutant subgroup than patients with METex14 mutations (median PFS, 9.1 versus 2.1 months, p = 0.025). Correspondingly, the overall survival (OS) was significantly longer in MET-non-ex14-mutant subgroup than their wild-type counterparts (median OS, not reached versus 11 months, p = 0.039). Additionally, patients with MET-non-ex14 mutations exhibited relatively better OS versus METex14-mutant patients (median OS, not reached versus 18 months, p = 0.175). Conclusions: MET-non-ex14 mutations were associated with higher TMB, improved DCB rate, and could act as a favorable prognostic biomarker in ICIs-treated NSCLC patients.

Background. We investigated the efficacy of TILs and anti-PD1 combination therapy in patients with metastatic cervical cancer with low MSI expression and PDL1-negative. Methods. A total of 80 patients were put on TILs and anti-PD1 combination therapy, and the progression-free survival time (PFS) and overall survival time (OS) were assessed by Kaplan–Meier analysis. Univariate and multivariate analyses were performed to identify factors that could predict the prognosis of metastatic cervical cancer in the previously described patients. Results. The objective response rate was 25%, whereas the mPFS and mOS were 6.1 and 11.3 months, respectively. The therapeutic efficacy was influenced by the characteristics of TILs, infection with HPV, and development of fever just after the therapy. Conclusion. Overall, our results show that the combination therapy of TILs and anti-PD1 significantly improves the prognosis of metastatic cervical cancer.

10574 Background: Biomarkers predicting efficacy of chemotherapy are highly desirable. Fiber array scanning technology (FAST) is a novel method of detecting circulating tumor cells (CTCs) that does not employ an EpCam enrichment step. The purpose of this study was to use FAST to evaluate ERCC1 expression on CTCs to determine whether ERCC1 expression correlates with progression-free survival (PFS) in patients who received platinum-based chemotherapy for metastatic non-small-cell lung cancer (NSCLC). Methods: Peripheral blood from one hundred enrolled patients with metastatic NSCLC was collected by two institutions (Stanford Cancer Institute and Billings Clinic Cancer Center). FAST was used to identify individual CTCs on immunofluorescence by pancytokeratin antibodies. Nuclear localization of ERCC1 expression by immunofluorescence was quantified on individual CTCs. Total patient ERCC1 levels were determined from the average expression of all the CTCs in each patient sample. Fifty-seven of the one hundred patients enrolled received platinum chemotherapy. Seventeen of those fifty-seven patients (30%) had ≥ 2 evaluable intact CTCs and were analyzed retrospectively. Linear regression (F-test) was used to evaluate the correlation between ERCC1 expression and PFS. Kaplan-Meier survival analysis (log-rank test) was used to compare PFS in patients with CTCs with no detectable ERCC1 expression versus patients with CTCs that expressed any level of ERCC1. Results: PFS decreased with increasing ERCC1 expression (P<0.04 F-test, linear regression). Lack of ERCC1 expression was associated with longer PFS (266 days vs. 172 days, log-rank test P<0.02). The difference in survival was statistically significant with a hazard ratio of 4.20 (95% CI 1.25-14.1, p<0.02, log-rank test). Conclusions: In this small study, using FAST to isolate CTCs, low expression of ERCC1 on evaluable CTCs correlated with increased PFS in patients with metastatic NSCLC who received platinum chemotherapy. A larger, prospective study to validate these retrospective results is warranted.

e13034 Background: This study assesses the impact of 6 cycles of adjuvant TMZ (conventional arm) versus 12 cycles (Extended arm) on Progression free survival (PFS), evaluate the toxicity and correlate the outcome with EGFR, P53 and MIB I labelling Index. Methods: Between December 2010 to October 2012, 36 post operative patients of Glioblastoma between age 18-65 years and Karnofsky Performance Score (KPS) ≥ 70 were included. Patients were randomized to receive Radiation with a dose of 60 Gray in 30 fractions over 6 weeks at 2 gray/fraction with concomitant TMZ (75 mg/m2/day) and Adjuvant therapy with either 6 or 12 cycles of TMZ(150 mg/m2 for 5 days, 28 days cycle). Patients were then assessed monthly clinically and imaged with MRI/CT every 3 monthly or when symptomatic. Toxicity was assessed using CTCAE version 3.0. Statistical Analysis was done using SPSS version 17.0.Kaplan Meier method was used for analysis of survival and log rank test was used for assessing the impact of variables on survival. Results: Of 36 patients, 18 patients were treated in each arm. Median age and KPS in both the arms was 47 years and 80 respectively. 44 % patients in the conventional arm and 50% patients in the Extended arm underwent complete surgical resection. 22% patients in the conventional arm and 28% in the extended arm did not complete their intended treatment. Grade ¾ Thrombocytopenia was seen in 16% in the extended arm and 0% in the conventional arm.EGFR, P 53 and MIB 1 >20% was seen in 26%, 45% and 20% patients respectively, overall. Median follow up was 18 months for both the arms (Range 10-23 months).At last follow up,8 patients in each arm had progression. Median PFS was 10 months vs.18.4 months (p 0.47) in conventional and extended arm respectively. On Univariate analysis, patients with KPS ≤ 80 had poorer survival than those >80 (Median PFS 9.5 Months vs. 16.9 Months; p 0.02).Age, extent of resection, EGFR, P53, MIB 1 did not significantly alter survival in the two treatment groups. Conclusions: Our study showed that schedule of extended Temozolomide is well tolerated by patients and tend to have better progression free survival. Further prospective randomized studies are needed to validate the findings of our study.

92 Background: ToGA study showed superiority of adding T-mab to standard chemotherapy and a positive correlation between HER2 expression levels and the T-mab efficacy. In gastric cancer IHH is frequently recognized but its clinical impact on T-mab efficacy is unclear. Methods: Patients who were treated with T-mab and had surgical specimens available for IHC test were retrospectively examined. When all tumor cells overexpressed HER2 protein by IHC, the tumor was defined as non-HER2-heterogeneous. The others were defined as HER2-heterogeneous. Progression-free survival (PFS) and overall survival (OS) were estimated using by Kaplan-Meier methods and compared by the log-rank test. The level of significance was set to p<0.05 and all statistical tests were two-sided. Results: 23 patients were enrolled. Their median age was 68 years and 83% were male. PS 0, GEJ cancer, intestinal type histology, visceral metastasis (lung or liver), and previous chemotherapy were found in 57%, 35%, 83%, 57%, and 57% of them, respectively. After a median follow-up of 11.3 months, the median OS, PFS, and overall response rate were 14.4 months, 10.8 months, and 62.5%, respectively. All tumors were IHC3+, and 13 were non-HER2-heterogeneous and 10 were HER2-heterogeneous. There was no significant difference in clinicopathological features between the two groups. Median PFS in non-HER2-heterogeneous group (21.9 months) was significantly longer than that in HER2-heterogeneous group (8.6 months), (HR: 0.24 [0.06-0.91], P=0.024). Median OS in non-HER2-heterogeneous group was not reached while that in HER2-heterogeneous group was 12.9 months (HR: 0.29 [0.06-1.42], P=0.102). A higher rate of response to T-mab was seen in non-HER2-heterogeneous group than in HER2-heterogeneous group, though the difference was not statistically significant (75% vs. 50%, p=0.608). Conclusions: IHH might have robust clinical impact on T-mab efficacy for HER2 positive GC. These findings should be validated by independent large cohorts and further molecular correlative analyses are warranted.

e17088 Background: Immuno-oncology (IO) treatment demonstrated to improve Overall Survival (OS) in metastatic renal cell carcinoma (mRCC). The prognostic impact of previous citoreductive nephrectomy (CN) and radical nephrectomy with curative intent in patients (pts) treated with IO is not well defined. Methods: 229 eligible pts, with a least one radiological assessment of response according to the RECIST 1:1 criteria, were retrospectively collected from 16 Italian referral centers. Baseline characteristics, outcome data including progression-free survival (PFS) and OS were collected. Kaplan-Meier method and log-rank test were performed to compare PFS and OS between groups. Results: 153(66.8%) pts received IO as second line, 61(26.6%) as third line and 15(6.6%) pts as further line. 54 pts (23.6%) were good risk, 144(62.9%) were intermediate and 31(13.5%) were poor risk according to IMDC score. 189(82.5%) pts underwent nephrectomy (of them 72(32.4%) pts had synchronous metastatic disease and underwent CN), while 40(17.4%) pts did not. Nephrectomy was performed before IO treatment. ECOG PS, at the beginning of IO, was 0 for 167 pts (72.9%), the other 62 (27.1%) had ECOG PS 1 or 2. At a median follow up time of 17.5 months (mo), 13 (5.7%) pts are still in treatment while 216 (94.3%) experienced progression. 81 (35.3%) pts were treated after IO progression with mTOR and VEGFR inhibitors. 63 (27.5%) pts continued IO beyond progression. G3-G4 iAE were reported in 46 pts (20%). Median IO-PFS was 4.5 months in pts who did not undergo nephrectomy and 2.9 mo in pts who did (HR log rank 0.713, 95%CI 0.4788 to 1.063; p= 0.0582). Median IO-OS was 18.4 mo in pts who underwent nephrectomy and 10.3 mo in pts who did not (HR log rank 1.915, 95%CI 1.118 to 3.281; p= 0.0024). The difference in OS was irrespective of the IMDC criteria and the lines of treatment. Conclusions: In our real world experience, in mRCC pts treated with IO, previous nephrectomy was associated with a better outcome in terms of OS with all the limitations of a retrospective collection.
