    Abstract: e15502 Background: mUC is a chemotherapy sensitive tumor. Currently, CGP and MVAC are the most active regimens in this setting. According to Norton and Simon hypothesis, the administration of two sequential non cross-resistant, dose-dense chemotherapy regimens may target different cancer cells, avoid drug resistance, improve response rate and CR. Methods: Patients with histological diagnosis of mUC, PS 0–2 (ECOG), adequate organ function and no previous systemic regimens were treated with 4 cycles of CGP dose-dense (Gemcitabine 1000 mg/m2 d 1, Paclitaxel 140 mg/m2 d 1, Cisplatin 70 mg/m2 d 2 plus PegFilgrastim 6 mg on day 3, every 2 weeks) followed by 4 cycles of M-VAC (Methotrexate 30 mg/m2 d 1,Vinblastine 3 mg/m2 d 2, Doxorubicin 30 mg/m2 d 2, Cisplatin 70 mg/m2 d 2 plus Pegfilgrastim 6 mg on day 3 every 2 weeks). All were evaluated with CT scan at the baseline, after 4 cycles, at the end of chemotherapy and then every 3 months for two years and 6 months thereafter. Metastatic sites included retroperitoneal nodes, lung, liver and bone. Results: From January 2007, 35 consecutive pts followed in the same oncology institution were included. Male were 74%; median age 65 years; median PS ECOG was 1; Bajorin risk factors was 0 in 37%, 1 in 43%, 2 in 20%. All pts were hospitalized for three days and received chemotherapy with hydration and supportive therapy. After the first 4 cycles of CGP we observed 14.3% CR, 48.6% PR, 22.9% SD and 14.3% PD. After the 4 sequential cycles of M-VAC we observed a global 37.1% of CR, 25.7% of PR, 8.6% of SD and 28.6% of PD. Median TTP was 9.9 months ( 95 % CI, 7.53-14.83) and median OS was 24.27 months ( 95 % CI, 10.03-38.43). Main grade 3–4 toxicity included asthenia ( 27%), anemia (21%), neutropenia (12 %), febrile (9%), thrombocytopenia (9%) and peripheral neuropathy (6 %). After a median follow up of 33 months, 6 of 13 patients who obtained a complete response are free of disease. Conclusions: These data confirm that the sequential use of this two dose-dense regimens is very active and 17 % of patients maintained a CR status.

    Abstract: 4112 Background: TCF is a standard first line option for GEC. The Norton-Simon hypothesis suggests that chemotherapy efficacy can be enhanced by decreasing intervals between cycles. We previously reported on the high activity of TCF-dd in GEC (Tomasello 2010). The aim of this study is to investigate the efficacy and safety of this intensified dose-dense regimen in a single-center large cohort of patients (pts). Methods: 150 pts with measurable or evaluable GEC, PS 0-2, with adequate organ function, treated in our center from 2004 to 2012 received TCF-dd: Docetaxel (60-85 mg/m2 d 1), Cisplatin (50-75 mg/m2 d 1), l-Folinic Acid (100 mg/m2 d 1-2), 5-FU (400 mg/m2 bolus d 1-2, and 600 mg/m2 as a 22 h continuous infusion d 1-2), plus Pegfilgrastim 6 mg d 3, every 14 days. Pts aged ≥ 65 years received the same schedule with a dose reduction by 30%. Analysis was based on the intention to treat population. Results: At a median follow-up of 44 months, 128 pts were evaluable for response, all for survival. Median age 65 (range 31-81), M:F 112:38. 17 pts (11%) with locally advanced inoperable GEC, 133 pts (89%) with metastatic GEC. Metastatic sites: liver 40%, peritoneum 31%, bone 14%, lung 12%. A median of 4 cycles (range 1-7) per patient was administered. 33% required a dose reduction. 33% were treated without any delay. 10 CR, 74 PR, 24 SD and 20 PD were observed, for an ORR of 66% (95% CI 57-74). Median OS was 13 months (95% CI 9.7-14.2). Most frequent grade 3/4 toxicities: neutropenia (34%), asthenia (28%), thrombocytopenia (17%), hypokalemia (16%), diarrhea (11%), febrile neutropenia (10%), anemia (9%), and stomatitis (4%). 11 pts (7%) [7 metastatic, 4 locally advanced] became operable after TCF-dd and underwent surgery. We identified 12 metastatic pts (8%) with overall survival 〉 3 years and 7 (5%) still maintaining a long lasting CR at the time of the current analysis. Conclusions: TCF-dd in GEC is very active and may be an option for conversion therapy. Toxicity can be relevant and requires a careful monitoring.

    Abstract: 4097 Background: MGC is a chemosensitive tumour. According to the Norton-Simon hypothesis, a reduction of tumor burden could best be achieved by shortening the interval between the cycles, and the resistance might be overcome by switching from initial chemotherapy to a new, non cross-resistant one. We previously reported on the high efficacy of a new strategy using 2 sequential, non cross-resistant chemotherapy regimens in MGC (Cancer Chemother Pharmacol 11 Jan; 67 (1): 41-8). Aim of this study is to evaluate this therapeutic approach in a larger case series. Methods: 43 patients (pts) treated at our centre from November 04 to April 11 were included. All pts were chemo-naïve and received 4 cycles of TCF-dd (see reference above for doses) every 2 weeks. Subsequently and irrespective of their response, they received 4 cycles of COFFI (see reference above ) every 2 weeks. In both regimens pegfilgrastim 6 mg sc on day 3 was included. Results: Median age: 63; 74% male. PS 0-1. After the first regimen (TCF-dd) 43 pts were evaluable for response.We registered 3 CR, 27 PR, 7 SD, 5 PD and 1 not evaluable for an ORR at ITT of 70% (95% CI, 58-85). All pts proceeded to the second regimen (COFFI) and 40 pts were evaluable for response. The 3 CR observed after TCF-dd were maintained. Among the 27 pts with PR after TCF-dd, 2 achieved CR, 14 improved the response, 6 maintained PR, 3 progressed. Among the 7 pts with SD after TCF-dd, 1 achieved CR, 3 achieved PR, 2 progressed and 1 is not valuable. Among the 5 pts with PD after TCF-dd, 1 achieved CR, 4 achieved RP. After COFFI we observed 5 CR, 21 PR, 9 SD and 5 PD. The ORR in the 40 pts was 60% (95% CI, 50-80). Considering both regimen ORR was 93%. mTTP was 12.1 months (95% CI, 8,1-16,2). mOS was 16.1 months (95% CI, 12.7-21.6). At Dec '11, 4 out of 8 pts who achieved CR are alive and disease free. Most frequent G3-4 toxicities were: astenia (32%), neutropenia (35%), anemia (14%), neurotoxicity (21%). Conclusions: The study confirms that a sequential dose-dense strategy using TCF-dd followed by COFFI is feasible and highly effective and deserves to be tested in a randomized study which is on going.

    Abstract: e14532 Background: Biomarkers predicting response to checkpoint inhibitor are needed to better select patients most likely to benefit from treatment. We observed that baseline absolute lymphocyte count (ALC) can predict durable responses to anti-PD-1 antibodies in various malignancies. Methods: This is a retrospective analysis of patients with advanced solid tumors treated with anti-PD-1 antibodies. Pembrolizumab was given at 2 mg/kg every 3 weeks, Nivolumab at 3 mg/kg every 2 weeks. Peripheral ALC and absolute neutrophil count (ANC) from routine safety labs were collected at baseline, cycle 4 and cycle 8. Evaluation of response was based on irRECIST. Neutrophil lymphocyte ratio [NLR = ANC/ALC] was stratified by ≤4 or 〉 4. The lymphocyte count cutoff was 1000/mm3. Time to progression (TTP) and overall survival (OS) were estimated with the Kaplan-Meier method. Differences between groups were estimated with the log rank test. Results: We have retrospectively evaluated 40 patients with unresectable stage III/IV Non Small Cell Lung Cancer (squamous n. 17; 42.5%, adenocarcinoma n. 7; 17.5%), Malignant Melanoma (n.11; 27.5%), Renal Cell Carcinoma (n.5; 12.5%) treated with anti-PD-1 antibodies. 6 pts (15%) received treatment as 1 st line, 14 pts (35%) as 2 nd line, 20 pts (15%) as ≥ 3 rd line. We observed a 29% partial response (PR), 31% stable disease (SD) and 40% progressive disease (PD). The overall response rate (ORR) was 29% [I.C. 95% 13-42]. Median TTP was 5.5 months [IC 95% 3.3-NR] . Median OS was not reached. Pts with baseline ALC ≥1000/mm3 had significantly longer TTP (median value not reached), compared with those who had ALC 〈 1000/mm3 (median TTP 2.8 months), p = 0.01. There was also a trend for longer TTP in patients with NLR 〈 4 vs ≥4 (4.9 vs 10.5 months, p 0.44). Conclusions: In our observation baseline ALC ≥1000/mm3 is a predictive biomarker of prolonged TTP in patients treated with anti-PD-1 antibodies. The potential predictive value of this test should be prospectively validated.

    Abstract: e15086 Background: Gastric cancer is more common in elderly pts with its highest incidence around the seventh decade of life. Most oncologists are reluctant to treat this population with the most active polichemotherapy combinations because of safety concerns. Subgroup analyses of elderly pts enrolled in European studies show limited and conflicting data.We previously reported on the feasibility and high activity of a dose-dense TCF regimen (Tomasello 2010). This is a retrospective analysis of efficacy and safety of this schema in the elderly pts subgroup (≥ 65 years). Methods: From Nov 2004 to Jan 2013, 119 consecutivepts with MGC, PS 0-2, not previously treated, received Docetaxel 70 mg/m 2 d1, Cisplatin 60 mg/m 2 d1, l-Folinic Acid 100 mg/m 2 d1-2, followed by 5-FU 400 mg/m 2 bolus d1-2, and then 600 mg/m 2 22 h c.i. d1-2, every 2 weeks, plus Pegfilgrastim 6 mg on day 3. Pts aged ≥ 65 years (60) received the same schedule with doses reducted by 30%. Results: Overall pts characteristics: 76% male, 24% female; median age: 65, range 31-81. A median of 4 cycles was administered. 102 pts were evaluable for response (86%) and all for toxicity. In pts aged ≥ 65 y, we observed 5 CR (8%), 26 PR (43%), 10 SD (17%) and 7 PD (12%); in younger pts: 3 CR (5%), 32 PR (54%), 9 SD (15%) and 10 PD (17%); ORR by ITT was 56% (95% CI 45-64). Median OS was 11,2 months (95% CI 9,4-14,1); in elderly and younger pts was 11,2 (95% CI 7,3-15,1) and 11,8 (95% CI 9,2-16,2), respectively. Out of 48 evaluable pts aged ≥ 65 years, 24 (50%) were treated at full doses without any delay. In the elderly most frequent grade 3-4 toxicities were: neutropenia (13%, p 〈 0.0001), leucopenia (7%), thrombocytopenia (18%), anemia (3%, p=0.02), febrile neutropenia (8%), asthenia (27%), diarrhea (10%), nausea/vomiting (10%) and hypokalemia (17%); in the younger: neutropenia (56%), leucopenia (31%), thrombocytopenia (22%), anemia (15%), febrile neutropenia (15%), asthenia (41%), diarrhea (15%), nausea/vomiting (22%) and hypokalemia (20%). Conclusions: This study shows that elderly pts can be safely treated with a TCF-dd regimen with a 30% dose reduction achieving similar efficacy results as younger pts with lesser toxicity.
