13529 Background: In British Columbia (BC), FOLFIRI and FOLFOX were approved for the treatment of MCRC in 2002. The effect on survival of various treatment and patient related factors was determined for patients with MCRC treated with sequential doublet chemotherapy. Methods: Eligible patients received either FOLFOX or FOLFIRI first-line with a cross over to the alternative regimen for second-line therapy. Patient records were retrospectively reviewed for patient and disease characteristics, treatment, toxicity and survival. Analysis of survival was performed by the Kaplan-Meier method. Results: Between March 2002 and June 2004, 106 new patients met the criteria above. Sixty five patients were treated with a sequence of FOLFOX-FOLFIRI (Group A): 67% M, median age 57y, rectal 20%. Forty-one were treated with the sequence FOLFIRI-FOLFOX (Group B): 64% M, median age 58y, 27% rectal. Survival was statistically similar in both groups. Progression requiring second line chemotherapy within 4 weeks of a first line treatment was associated with inferior survival (13 months vs. 21 months (p<0.018). Grade 3 or 4 toxicity was experienced in 27.5% of the patients treated with FOLFOX and 22% of the patients treated with FOLFIRI. Conclusions: In the general population with MCRC, the median survival achieved with sequential doublet therapy is consistent with that reported in clinical trials. A superior sequence was not identified. The median number of first line chemotherapy cycles with FOLFOX and FOLFIRI was similar, reflecting the general clinical practice in BC to give 10 - 12 cycles of therapy followed by a planned break. Patients who required initiation of second line chemotherapy within 4 weeks of stopping the first line therapy experienced an inferior prognosis. Univariate and multivariate analysis showed no significance of sex, age, site (colon versus rectal), and ECOG status as predictive factors.

4549 Background: No established second-line chemotherapy exists for patients (pts) with MGC failing to respond or progressing after first-line chemotherapy. This study was designed to determine the efficacy and safety of FOLFIRI combination used as second-line therapy in pts with MGC not previously treated with regimens containing fluoropyrimidines. Methods: Pts with measurable distant metastases, previously treated with a combination of epirubicin, docetaxel and cisplatin or oxaliplatin as first-line therapy, received irinotecan 180 mg/mq (150 mg/mq in pts >70 ys old) as a 1-h infusion day 1; leucovorin 100 mg/mq/day followed by bolus fluorouracil (FU) 400 mg/mq and a 22-h infusion of FU 600 mg/mq day 1–2, every 2 weeks for a maximum of 12 cycles or until disease progression, unacceptable toxicity or patients refusal. Endpoints were response rate (RR), time to progression (TTP), overall survival (OS) and safety. Results: 38 pts were enrolled: M/F 23/15; median age 66 ys (34–75); median ECOG PS 1 (0–2); number of metastatic sites 1/2/≥3: 9/18/11 pts, respectively. A total of 223 cycles was performed (median 6, range 2–12). One CR and 8 PR were observed for an overall RR of 24% (95% CI, 11–39 %). Disease remained stable in 11 pts. Median TTP was 4.0 months (95% CI, 2.9–5.1) and median OS was 6.2 months (95% CI, 4.7–7.7). Grade 3/4 neutropenia, thrombocytopenia and anemia occurred in 29%, 3% and 8% of pts, respectively. Febrile neutropenia was seen in 2 pts (5%). Other grade 3 toxicities included diarrhea in 5 pts (13%), mucositis in 2 pts (5%) and vomiting in 2 pts (5%). There were no treatment related deaths. Conclusions: FOLFIRI is an active and well tolerated second-line regimen for MGC pts not previously treated with fluoropyrimidines. No significant financial relationships to disclose.

13511 Background: Treatment until progression or planned interruption of first line chemotherapy is common in the therapy for metastatic colorectal cancer and are upon the discretion of the oncologist. A retrospective analysis was performed to determine the impact of these differing therapeutic strategies on overall survival. Methods: Eligible patients were treated between 2002 to 2004 in British Columbia. All patients received chemotherapy with both FOLFOX and FOLFIRI, either first or second line. Records were retrospectively reviewed for treatment interruption, efficacy and toxicity. Overall survival was the primary endpoint. Results: 101 patients were identified. Twenty-three patients who progressed before receiving 8 cycles of chemotherapy and 9 patients who stopped their chemotherapy due to toxicity were excluded. The remaining patients were analyzed for survival. Twenty-three patients were treated to progression of whom 6 received first line FOLFIRI and 17 received first line FOLFOX. The mean number of cycles of first line therapy was was 11.5. Forty six patients received a planned break. Of these, 21pateints received first line FOLFIRI and 25 patients received first line FOLFOX. Mean number of cycles of first line therapy was 9.7. Median survival of patients treated to progression was 16 months compared to 22 months for patients with planned break of therapy (p=0.003). The Hazard ratio was 2.3 (p=0.01) in favor of patients who had a planned break. Uni-variate and multivariate analysis showed no significance of sex, age, site (colon versus rectal), sequence and ECOG status as predictive factors. Conclusion: In this study, patients who were treated until progression with first line chemotherapy with either FOLFOX or FOLFIRI had an inferior survival. Possible explanations for the detrimental hazard ratio for patients treated to progression are decreasing reserve for second line therapy when first line therapy is prolonged and increasing resistance to 5-FU based therapy with prolonged exposure. As this is a retrospective, observational study, other variables not captured by the modeled covariates that may have influenced results. This data suggests that treating to best response and then allowing a break does not detrimentally affect survival. No significant financial relationships to disclose.

e15613 Background: Despite high response rates (RRs) with first-line platinum-based chemotherapy in advanced urothelial carcinoma (UCC), treatment after first-line failure remains unclear. The present multi-center phase II trial evaluated the tolerability and efficacy of weekly docetaxel as second-line chemotherapy for UCC. Methods: Between Aug 2010 and Sep 2012, 31 patients with measurable UCC, progressive after one prior platinum-based chemotherapy for advanced disease, were treated with docetaxel 30 mg/m2 on days 1 and 8. Treatment was repeated every 21 days until disease progression or unacceptable toxicity. The primary endpoints were the RR, progression-free survival (PFS), and safety. To detect a 20% difference in RR (6% vs. 26%), 28 eligible patients were required. Results: All 31 patients were previously treated with gemcitabine/platinum and had Bellmunt risk of one or more. The patients’ median age was 64 years (range, 40 to 79) and 31 (100%) patients had an ECOG performance status of 1. A total of 106 (median, 2; range, 1 to 16) chemotherapy cycles were delivered. Although fatigue (13%) and anorexia (6%) were the most frequently observed grade 3 or 4 toxicities, safety profiles were generally mild and manageable. One patient developed prolonged thrombocytopenia which led to treatment discontinuation but was resolved thereafter. In an intent-to-treat analysis, two (6%) patients achieved objective response, which maintained for 3.0 to 7.8 months. Eight patients experienced disease stabilization, resulting in a disease control rate of 32%. The median PFS and overall survival were 1.4 (95% CI, 1.3 to 1.6) and 9.6 (95% CI, 7.8 to 11.4) months, respectively. Conclusions: Second-line chemotherapy with weekly docetaxel was well tolerated but demonstrated modest antitumor activity in patient with advanced UCC who had progression after first-line platinum-containing regimen and poor prognostic factors. Clinical trial information: NCT01711112.

14107 Background: Recent advances in the treatment of pancreatic cancer might influence the management of locally advanced and metastatic disease, nonetheless prognosis remains dismal (1-year survival rates: 24%). The impact on survival of palliative second-line therapy is hotly debated. Methods: We retrospectively reviewed the clinical records of 103 pancreatic cancer patients admitted to San Camillo/Forlanini Hospital (Rome, Italy) and the Oncology Institute of Southern Switzerland during the period June, 1997 to August, 2005 [60 males, 43 females, median age 65 years (range 43–80); median ECOG performance status (PS): 1]. All patients received Gemcitabine as single agent (90%) or in combination with Oxaliplatin (10%) as upfront therapy. A total of 12 fluoropyrimidine-based salvage regimens were administered to 46 patients in the second line setting. Best supportive care was selected in 57 patients after failing first line therapy. Results: Of 103 evaluable patients, first line chemotherapy produced overall tumor growth control of partial response (PR) and stable disease(SD) by RECIST criteria of 52.4% with a median progression free survival (PFS) of 4.6 months. Multivariate analysis revealed that the most important prognostic factor for PFS was the patient’s PS, as patients with PS of 1–2 at diagnosis had significantly worse results than patients with PS = 0 (First line PFS: 110 days vs 193 days, p<0.05). Baseline CA19–9 and number of metastatic sites were not independent prognostic factors for better first-line PFS. PR was observed in 8/46 patients (17.3%) who received second line chemotherapy, SD in 10 (21.7%), and 28 patients progressed (61%). Median overall second line PFS was 3.2 months. Patients who had responded to first-line Gemcitabine were more likely to respond or attain stable disease with second-line treatment, with a PFS of 5.6 vs 2.85 months (p<0.05). The overall survival for all evaluable patients was 8.4 months. 1-year survival was 52% for patients treated with second line therapy. Conclusions: These results are consistent with historical studies and suggest that fluoropyrimidine-based salvage regimens have marginal but definite activity and should be considered in patients who have responded to first line chemotherapy with an optimal PS.

127 Background: Cetuximab plus chemotherapy is a first-line treatment option for metastatic RAS wild type colorectal cancer patients. Currently, no data are available on continuing cetuximab or changing bevacizumab as second-line therapy beyond first-line cetuximab-based chemotherapy. Methods: Patients (aged ≥18 years) with metastatic, histologically and genetically confirmed wild-type KRAS, NRAS and BRAF colorectal cancer progressing after first-line cetuximab plus chemotherapy were randomly assigned (1:1 ratio) to second-line chemotherapy with cetuximab (arm A) or with bevacizumab (arm B) 2·5 mg/kg per week equivalently. The choice between oxaliplatin-based or irinotecan-based second-line chemotherapy depended on the first-line regimen (switch of chemotherapy). The primary endpoints were progression-free survival (PFS) and objective response rate (ORR). The second endpoint was overall survival (OS). Results: 77 Patients (from July 1, 2016 to Sept 20, 2019, 77) were randomized (41 in arm A and 36 in arm B). ORR was 29.3% and 19.4% in Arm A and Arm B ( p= 0.31). PFS was 7.2 months (95% CI 5.2–9.2) for Arm A and 5.9 months (95% CI 5.1–6.7) for Arm B ( p= 0.677). OS was 18.5 months (95% CI 15.1–21.8) for Arm A and 17.5 months (95% CI 15.4–19·7) for Arm B ( p= 0.444). Patients with ECOG PS 0 had significantly longer PFS and OS than ECOG PS 1 in second-line therapy whether cetuximab or bevacizumab combined with chemotherapy. ECOG 0 group vs ECOG 1 group, PFS was 8.7 months vs 4.6 months (p = 0.00) and OS was 21.2 months vs 12.3 months (p = 0.00). Moreover, ETS may predict efficacy of second-line continued cetuximab. The most frequently grade 3–4 adverse events in both arms were neutropenia (19.4% VS 16.7%), diarrhea (7.5% vs 11.1%), and nausea(10% vs 13.9%). Conclusions: Continuing cetuximab or changing bevacizumab plus standard second-line chemotherapy in patients with metastatic wild-type KRAS, NRAS and BRAF colorectal cancer after first-line cetuximab plus chemotherapy have similar clinical benefits. ECOG score is an independent predictor of prognosis and second-line treatment efficacy for colorectal cancer.
