Ziele: Die Strahlentherapie ist als palliative Behandlung bei rezidivierendem Ovarialkarzinom gebräuchlich, jedoch wurde bisher nicht geklärt, ob sie die Prognose verbessert.Methoden: Die Wirkung einer Strahlentherapie und die damit einhergehenden unerwünschten Ereignisse bei Patientinnen mit rezidivierendem Ovarialkarzinom wurden anhand deren Patientenakten untersucht.Ergebnisse: Hierbei wurden 46 Patientinnen betrachtet: 33 Patientinnen, deren rezidivierende Läsionen auf das Bestrahlungsfeld begrenzt waren (therapeutische Bestrahlungsgruppe; TBG), und 13 Patientinnen, bei denen die rezidivierenden Läsionen zum Teil außerhalb des Bestrahlungsfelds lagen (palliative Bestrahlungsgruppe; PBG). In der TBG betrug die Ansprechrate (response rate; RR) 66%, die Rate der Krankheitsbeherrschung (disease control rate; DCR) 100%, das progressionsfreie Überleben (progression-free survival; PFS) 10 Monate und das Gesamtüberleben (overall survival; OS) 20 Monate. Das PFS nach Bestrahlung war signifikant länger als nach Bestrahlung mit unmittelbar vorausgehender Chemotherapie. Das PFS der Patientinnen mit Rezidivläsionen innerhalb des Beckens war länger als bei den Patientinnen, deren Läsionen zum Teil außerhalb des Beckens lagen. Zwischen dem PFS nach Strahlentherapie und der Dauer seit der vorhergehenden Chemotherapie oder dem histologischen Typ bestand kein signifikanter Zusammenhang. In der PBG lagen die RR bei 30%, die DCR bei 90%, das PFS bei 2 Monaten und das OS bei 6 Monaten. Schwerwiegende unerwünschte Ereignisse traten selten auf.Schlussfolgerungen: Bestrahlung ist eine mögliche Option bei Chemotherapie-refraktärem, lokal begrenztem rezidivierendem Ovarialkarzinom.Übersetzung aus Oncology 2014;86:232-238 (DOI: 10.1159/000357269)

There is a lack of useful biomarkers for predicting the efficacy of anti–programmed death-1 (PD-1) therapy for advanced gastric and colorectal cancer. To address this issue, in this study we investigated the correlation between inflammatory marker expression and survival in patients with advanced gastric and colorectal cancer. Data for 111 patients with advanced gastric and colorectal cancer treated with anti–PD-1 regimens were retrospectively analyzed. Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and clinical characteristics of each patient were selected as the main variables. Overall response rate, disease control rate, and progression-free survival were primary endpoints, and overall survival and immune-related adverse events (irAEs) were secondary endpoints. The chi-squared test and Fisher’s exact test were used to evaluate relationships between categorical variables. Uni- and multivariate Cox regression analyses were performed, and median progression-free survival and overall survival were estimated with the Kaplan–Meier method. The overall response rate and disease control rate of anti–PD-1therapy in advanced gastric and colorectal tumors were 12.61 and 66.66%, respectively. The patients with MLR < 0.31, NLR < 5, and PLR < 135 had a significantly higher disease control rate than those with MLR > 0.31, NLR > 5, and PLR > 135 (P < 0.05). The multivariate analysis revealed that MLR < 0.31, BMI > 18.5, and anti–PD-1 therapy in first-line were associated with prolonged PFS. MLR < 0.31 and BMI > 18.5 were associated with prolonged overall survival. The irAE rate differed significantly between PLR groups, and PLR < 135 was associated with an increased rate of irAEs (P = 0.028). These results indicate that the inflammatory markers NLR, MLR, and PLR have clinical utility for predicting survival or risk of irAEs in patients with advanced gastric cancer and colorectal cancer.

128 Background: Irinotecan is a key drug in second- or further-line chemotherapy for patients with advanced gastric cancer. Continuous administration of trastuzumab beyond first progression is expected to contribute to the benefit of chemotherapy for HER2-positive gastric cancer. We assessed the efficacy and safety of combination chemotherapy with trastuzumab and irinotecan in Japanese patients with advanced HER2-positive chemo-refractory gastric cancer. Methods: Intravenous infusion of irinotecan every 2 weeks at a dose of 150 mg/m2; intravenous infusion of trastuzumab at a dose of 8 mg/kg on day 1 of the first cycle, followed by 6 mg/kg every 3 weeks. Administration of irinotecan and trastuzumab were repeated in independent schedules. The primary endpoint was disease control rate. The secondary endpoints were adverse events, response rate, time-to-treatment failure, progression-free survival, overall survival, and response rate stratified by prior trastuzumab use. This study was conducted by the Osaka Gastrointestinal Cancer Chemotherapy Study Group (OGSG). Results: From October 2012 to Augst 2014, 30 patients were enrolled and one patient withdrew before study treatment. Accordingly, 29 patients were assessable for efficacy and safety. The disease control rate was 65.5% [95% C.I. 45.7 - 82.1%], and the response rate was 20.7% [95% C.I. 8.0 - 39.7%]. The median progression free survival and the median overall survival were 3.7 and 7.5 months, respectively. The major grade 3/4 toxic effects were neutropenia (24%); anemia (24%); leucopenia (21%); anorexia (11%); fatigue (14%); hypoalbuminemia (24%); and hypokalemia (14%). One death (NOS) was considered to be related to the study. Conclusions: The results of combination Trastuzumab with irinotecan showed feasible and promising efficacy against advanced HER2-positive chemo-refractory gastric cancer. These findings indicated that trastuzumab continuation use might be beneficial. Clinical trial information: 000008626.

3527 Background: Apatinib is an oral highly-selective tyrosine kinase inhibitor (TKI) that blocks vascular endothelial growth factor receptor 2 (VEGFR-2). This exploratory study evaluated the efficacy and safety of apatinib monotherapy in patients with chemotherapy-refractory metastatic colorectal cancer. Methods: In this multicenter, single-arm, prospective study, 48 patients with metastatic colorectal cancer who had failed at least two lines standard chemotherapies including fluorouracil, oxaliplatin and irinotecan were recruited from 14 centers in Guangdong, China. Apatinib at a 500mg dose was administered daily continuously. Each cycle was 4 weeks (28 days). The primary endpoint was progression free survival (PFS). Secondary end points included overall survival (OS), objective response rate (ORR), disease control rate (DCR), quality of life (QoL) and toxicity. Results: A total of 48 patients was enrolled in the study from September 3, 2015 to June9, 2017. Four patients achieved a partial response, and 22 achieved stable disease, representing a response rate of 8.3% and a disease control rate of 60.4%. Median follow-up time was 10.3 months. Median progression-free survival (PFS) and overall survival (OS) of evaluable patients (n=41) were 4.7 months (95% confidence interval [CI] 3.7-5.9) and 9.7 months (95% CI 5.9-13.6). The most common grade 3 or 4 adverse events (AE) were hypertension (12.5%), hand-foot syndrome (10.4%), thrombocytopenia (10.4%), proteinuria (8.3%) and mucositis oral (6.3%). Conclusions: Apatinib monotherapy shows promising efficacy and manageable toxicities in patients with chemotherapy-refractory metastatic colorectal cancer. Further phase 3 trial is warranted.

631 Background: This study was designed to evaluate the influence of dose reduction and schedule modification on outcomes in patients with metastatic colorectal cancer (mCRC). Methods: Pooled datasets from two previous phase II trials of FOLFIRI (CCOG-0502; n = 36) and mFOLFOX6 (CCOG-0704; n = 30) in patients with mCRC were analyzed retrospectively. The RDIs of irinotecan and oxaliplatin were compared to response rate (RR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS). To assess the effects of dose reduction and time delay, we defined ‘dose index (DI)’ as the ratio of the actual delivered total dose to the planned total dose and ‘time index (TI)’ as the ratio of the planned duration to the actual duration of therapy. Relative dose intensity (RDI) was computed by multiplying DI by TI. DI and TI of irinotecan and oxaliplatin were compared to response rate (RR), disease control rate (DCR) and progression-free survival (PFS). Results: In patients receiving FOLFIRI therapy, the median DI and TI of irinotecan were 0.92 and 0.90, respectively. RRs were 59% vs. 12% in the higher vs. lower DI groups (p < 0.01), and 35% vs. 35% in the higher vs. lower TI groups (p = 1.00), respectively. Median PFS was 10.2 vs. 5.0 months in the higher vs. lower DI groups (p < 0.01), and 6.1 vs. 6.7 months in the higher vs. lower TI groups (p = 0.48), respectively. In mFOLFOX6 therapy, the median DI and TI of oxaliplatin were 0.97 and 0.82, respectively. RRs were 44% vs. 36% in the higher vs. lower DI groups (p = 0.65), and 44% vs. 36% in the higher vs. lower TI groups (p = 0.65), respectively. Median PFS was 7.7 vs. 6.7 months in the higher vs. lower DI groups (p = 0.13), and 8.5 vs. 5.9 months in the higher vs. lower TI groups (p = 0.02), respectively. Multivariate analyses showed that DI of irinotecan (HR 8.48; 95% CI, 2.94-24.51, p < 0.01) and TI of oxaliplatin (HR 2.74; 95% CI, 1.02-7.33, p = 0.04) were the independent prognostic factors for PFS. Conclusions: Dose reductions in irinotecan and time delays in oxaliplatin could have significant impact on PFS in patients receiving FOLFIRI and FOLFOX6, respectively.

463 Background: Addition of nab-paclitaxel to gemcitabine has recently been demonstrated in the clinical phase III trial MPACT to be beneficial for progression free survival, overall response rate, and overall survival in advanced pancreatic cancer patients. Any potential biologic activity of nab-paclitaxel in biliary cancer is hitherto unknown. Methods: A retrospective analysis of patients with advanced biliary cancer was undertaken to determine the disease control rate (CR+PR+SD), progression-free survival and overall survival in patients who had received nab-paclitaxel-based chemotherapy after failure of a platinum-containing first-line combination chemotherapy. Results: Eleven patients were identified. 4 of 11 patients received nab-paclitaxel as second line, 7 of 11 patients as a third-line treatment. 7 of 11 patients received nab-paclitaxel in combination with gemcitabine, while in 4 of 11 patients nab-paclitaxel was combined with fluoropyrimidine. The disease control rate seen with nab-paclitaxel was 81% (nine of eleven patients). Disease was progressive in one patient, and in one patient the response status is unknown yet. One patient received partial remission and 8 patients had stable disease. As of September 13th, 2014, three patients are still undergoing nab-paclitaxel combination therapy, but were censored by this date for analysis. The median time to progression was 4.9 months (2.3 – 18.9 months) for all patients (11/11 pts.), and 9.5 months for patients completed nab-paclitaxel treatment (8/11 pts.). Median overall survival for all eleven patients after initiation of nab-paclitaxel treatment was 7.3 month (2.6 – 21.8 month). The mean time of survival after diagnosis of advanced disease was 21.3 month, whereby 5 patients were alive at date of censoring. Conclusions: Nab-paclitaxel based chemotherapy can be an effective second-line regimen after platinum-failure in patients with advanced biliary cancer. In this small series, nab-paclitaxel appears to have a biological activity by controlling the disease and positively affecting survival. Randomized trials in this group of patients are urged.

e20522 Background: The aim of this study was to assess the efficacy of Antroquinonol in patients with stage IV NSCLC after failure in two-lines of anti-cancer therapy. Methods: Patients with stage IV non-squamous NSCLC who have failed at 2-4 lines of anti-cancer therapy were eligible, though early stage or naïve patients may voluntarily participate. A maximum of 30 evaluable patients were to receive Antroquinonol 600mg per day, of which 15 patients were to be KRAS-positive and 15 patients KRAS negative. The primary endpoint of the study was progression-free survival from the start of treatment to week 12 with disease control rate and overall survival as key secondary endpoints. Results: There were 31 patients enrolled with evaluable population 30 patients, of which 15 patients were KRAS positive and 15 patients KRAS negative. 73% were with at least two prior chemotherapy. The median PFS of 7 patients with 2 prior chemotherapy was 22.9 weeks (95% confidence interval [CI]: 5.0, 31.1); and 11 patients with more than 2 prior chemotherapy was 11.9 weeks (95% confidence interval [CI]: 6.0, 14.1), with a 1-year PFS of 11.4%. Of 11 patients who had had more than 2 prior chemotherapy, the median OS was 47.3 weeks (95% CI: 14.1,-), with a 1-year OS of 39.3%, and the overall disease control rate was 72.7%, with 100% in KRAS negative and 50% in KRAS positive. No systemic toxicities were observed. Conclusions: The monotherapy of Antroquinonol brought up higher disease control rates and longer progression-free survival and overall survival, compared with historical data. Although KRAS negative shows much better than KRAS positive group, Antroquinonol still work well with KRAS positive patients. Clinical trial information: NCT02047344.

BackgroundLenvatinib inhibits tyrosine kinases, including vascular endothelial growth factor (VEGF) receptor, fibroblast growth factor receptor, platelet-derived growth factor receptor alpha, RET proto-oncogene and KIT proto-oncogene, receptor tyrosine kinase. We assessed the efficacy and safety of lenvatinib in patients with metastatic colorectal cancer after failure of standard chemotherapies.Patients and methodsThis was an open-label, single centre, single-arm, phase 2 study. Eligible patients had unresectable metastatic colorectal adenocarcinoma, refractory or intolerant to fluoropyrimidine, irinotecan, oxaliplatin, trifluridine/tipiracil, anti-VEGF therapy and anti-epidermal growth factor receptor therapy (for tumours with wild-type RAS). Patients were treated with oral lenvatinib at 24 mg one time a day in 28-day cycles until disease progression or unacceptable toxicity. The primary endpoint was centrally assessed disease control rate. Secondary endpoints included safety, response rate, progression-free survival and overall survival. The planned sample size was 30 patients to expect a disease control rate of 60% with a threshold disease control rate of 35%, one-sided alpha of 5% and power of 80%ResultsBetween 24 October 2016 and 23 January 2018, 30 patients were enrolled; 11 (37%) and 19 (63%) had received 3 or ≥4 lines of prior chemotherapy for metastatic disease, respectively. The median number of lenvatinib cycles was 4 (range 1–13). The centrally assessed disease control rate was 70.0% (21/30, 90% CI 53.5% to 83.4%, one-sided p=0.0001); 2 patients had a partial response and 19 had a stable disease. Median progression-free survival was 3.6 months (95% CI 2.6 to 3.7). Median overall survival was 7.4 months (95% CI 6.4 to 10.8). The most common grade ≥3 adverse events were hypertension (53%), thrombocytopenia (10%), increased alanine aminotransferase and anorexia (7% each).ConclusionsLenvatinib showed promising clinical activity and was tolerated in patients with metastatic colorectal cancer after failure of standard chemotherapies.Trial registration numberUMIN-CTR, UMIN000023446 and JAMCCT-CTR, JMA-IIA00261.

Abstract Background Treatment options for metastatic breast cancer (MBC) refractory to anthracyclines and taxanes are limited. In a phase III trial, eribulin demonstrated a significant improvement in overall survival compared to treatment of physician’s choice, but had limited tolerability because of neutropenia and peripheral neuropathy. Based on prior studies of alternative treatment schedules with other therapies, we hypothesized that a low-dose metronomic schedule of eribulin would permit patients to remain on treatment more consistently without treatment delays, resulting in longer time to progression, and improved toxicity profile. Methods We conducted a multi-site single arm, phase II trial patients with MBC. All patients were treated with metronomic eribulin (0.9 mg/m2 administered intravenously on days 1, 8, and 15 of a 28-day cycle.) Treatment was continued until the patient developed disease progression, unacceptable toxicity, or chose to stop the study. Patients must have had prior taxane exposure. The primary endpoint was progression-free survival. Secondary end points were overall survival, response rate, and clinical benefit rate. Exploratory biomarkers were performed to analyze change in levels of circulating endothelial cells (CECs), circulating endothelial precursors, and carbonic anhydrase IX (CAIX) with response to therapy. Findings We consented 86 patients and 59 were evaluable for final analysis. Median age was 59 years; 78% had HER2 negative tumors. The median progression-free survival (PFS) was 3.5 months with overall survival (OS) of 14.3 months. Objective response rate was 15% with clinical benefit rate of 48%. Reported grade 3 neutropenia and peripheral neuropathy were 18% and 5%, respectively. Treatment discontinuation due to toxicity was seen in 3% of patients. Interpretation Metronomic weekly low-dose eribulin is an active and tolerable regimen with significantly less myelosuppression, alopecia, and peripheral neuropathy than is seen with the approved dose and schedule, allowing longer duration of use and disease control, with similar outcomes compared to the standard dose regimen.

Background Patients with locally advanced, recurrent or metastatic solitary fibrous tumour are often treated with bevacizumab and temozolomide based on the clinical efficacy reported in a case series of 14 patients. Given the rarity of solitary fibrous tumour, large trials are not feasible. We report the efficacy of this regimen based on a population-based analysis. Methods This was a population-based retrospective, multi-centre analysis using patient data from a provincial cancer registry and treatment database. Cases from June 2006 through October 2016 were identified for patients receiving bevacizumab and temozolomide for locally advanced, recurrent or metastatic solitary fibrous tumour or hemangiopericytoma, which is sometimes used to describe tumours arising from the meninges. The primary outcome was overall response rate. Secondary outcomes included time to response, progression free survival and overall survival estimated using the Kaplan–Meier method. Results Fourteen patients were identified: median age 59 (range 44–70), male 78.6%. Diagnoses were solitary fibrous tumour in 10 (71.4%) and hemangiopericytoma in four (28.6%), with metastatic disease in 10 (72.7%) patients. The most common primary sites were meninges in four (28.6%) and pelvis in three (21.4%) patients. The median follow-up was 15.5 months, with median treatment of four months. Overall response rate was 21.4% (no complete response, 3 partial response), with median time to response of four months. Median progression free survival, six-month progression free survival and overall survival were 17 months, 65.0%, and 45 months, respectively. Conclusions Efficacy of bevacizumab and temozolomide in solitary fibrous tumour appeared to be similar to that previously reported. Our findings confirmed that bevacizumab and temozolomide is an effective and tolerated treatment for this patient population.
