The Impact

161 Background: Body composition has emerged as an important prognostic factor in cancer patients. Especially, skeletal mass depletion has been associated with poor performance status, toxicity of chemotherapy and shortened survival in cancer patients. However, the impact of pre-treatment skeletal muscle index on survival or toxicity in metastatic gastric cancer patients remains uncertain. Methods: In this retrospective study, we reviewed 98 metastatic gastric cancer (mGC) patients who received S-1 based combination chemotherapy as first-line treatment from April 2006 to March 2013. Pre-treatment skeletal muscle mass was quantified by CT cross sectional area at the third lumbar vertebrae and evaluated as lumbar skeletal muscle index (SMI) (cm2/m2) after normalization for stature (m2). Patients were categorized into 2 groups depending on initial SMI: 35 patients with SMI ≤ 40 and 63 patients with SMI > 40. Results: Median overall survival was significantly shorter in the SMI ≤ 40 group than in the SMI >40 group (439 days versus 565 days; p= 0.03). Progression free survival was also better in the SMI> 40 group without statistical significance (175 days versus 151 days; p= 0.17). Toxicity (grade 3 or 4) was more common in the SMI ≤ 40 group than in the SMI >40 group. (41.1% versus 11.1%; p=0.001). In multivariate analysis, performance status of 2 (HR 4.711, 95%CI 1.065 to 20.832, p=0.04), presence of primary tumor (HR 2.322, 95%CI 1.007 to 5.357, p=0.04) and pre-treatment SMI (HR 2.525, 95%CI 1.145 to 5.568, p=0.02) were independent prognostic factors for OS. Conclusions: The present study suggests that skeletal muscle depletion at the initiation of first-line chemotherapy might be an independent prognostic factor for mGC patients.

e20563 Background: MPM is a highly aggressive pleural tumor associated with asbestos exposure and with limited survival despite systemic therapy. Histology is a prognostic factor and recently CheckMate 743 trial demonstrated survival benefit of immunotherapy in first line with some differences in the efficacy of chemotherapy according to histology. However, randomized trials who led to the approval of antifolate in mesothelioma did not include analysis of outcomes by histology. The objective of this study is to characterize the impact of chemotherapy according to histology in p with MPM at our institution. Methods: We review 189 MPM p diagnosed at Vall d´Hebron University Hospital between November 2002 and April 2020. Associations between clinical variables and outcome were assessed with Cox regression models and survival data were calculated by the Kaplan-Meier method. Results: Patient’s characteristics: median age 68 years (y) (45-88 y), males: 70%, performance status (PS)1: 69%, asbestos exposure: 75%, epithelioid subtype: 76%. First line chemotherapy was offered to 85% of p (66% cisplatin-pemetrexed and 27% carboplatin-pemetrexed). Median overall survival (OS) in overall population was 21.3 m (95%CI17.2-24.3). Epithelioid histology, PS 0, neutrophil-lymphocyte ratio <5 and treatment with cisplatin vs carboplatin were associated with significant improvements in OS (p<0.001). When we analyzed the survival of patients who received first line chemotherapy according to histology, we found that patients with epithelioid tumors had better PFS and OS. Median PFS for p with epithelioid tumors treated with chemotherapy in first line was 4.8 m versus 3.6 months non-epithelioid (HR1.5 CI95% 1.1-2.3; p=0.03). OS of epithelioid p treated with first line chemotherapy was 26.7 m versus 15.0 m non-epithelioid patients (HR2.25 CI95% 1.4-3.4; p<0.001). We analyzed if the differences in survival according to histology were due to type of systemic treatment received (Table). Conclusions: In our series, p with non-epithelioid tumors presented worse prognosis. We confirmed histology is a prognostic factor with better OS for p with epithelioid tumors. Moreover, we demonstrated better efficacy of chemotherapy in epithelioid tumors, although histology is not a predictive factor for the platinum agent sensitivity (p of interaction PFS=0.09, p of interaction OS= 0.65).[Table: see text]

64 Background: An altered expression of tumour angiogenesis-related factors has been constantly associated to a more aggressive phenotype and an increased relapse rate in several tumour types, including gastric cancer. Besides correlating with prognosis, tumour-driven angiogenesis seemed also able to influence response/resistance to chemotherapy in pre-clinical models. We examined the role of tumour angiogenesis genotyping in determining clinical outcome in metastatic gastric cancer patients receiving first-line chemotherapy. Methods: VEGF-A, VEGF-C, FLT1, KDR and FLT4 genotyping was performed on gastric tumours from 94 consecutive patients receiving platinum-based first-line chemotherapy. Results: Only theVEGF A rs25648 correlated with RR (PR = 18% among patients showing the VEGF A rs25648 CT or TT genotype vs. 44% among patients showing the VEGF A rs25648 CC genotype, p = 0.04). The VEGF A (rs2010963) and VEGF C (rs4604600 and rs7664413) correlated with mPFS and the VEGF A rs25648 and FLT4 rs307833 correlated with both mPFS and OS. Among other clinical variables tested (sex, age, ECOG performance status, gastrectomy, adjuvant chemotherapy, metastatic sites and second-line chemotherapy) only the use of second-line chemotherapy correlated with improved overall survival (10.2 months vs. 6.3 months for patients who received or did not receive second-line, p= 0.003). At multivariate the VEGF A rs25648 maintained an independent role in determining both median PFS (HR = 1.65 95% CI: 1.12-2.78, p= < 0.0001) and OS (HR = 1.58, 95% CI: 1.17-2.65, p = 0.0003). The use of second-line chemotherapy also showed an independent role in determining median OS (HR = 0.58, 95% CI: 0.38-0.87, p= 0.003). Conclusions: VEGF A rs25648 genotyping may help identifying a patients subgroup unlikely to benefit from a first-line, platinum-based combination and potentially candidate to alternative therapy choices. Our data may help designing future clinical trials with the aim to investigate the outcome of different chemotherapy regimens in different patients groups prospectively stratified according to angiogenesis profile.

558 Background: Muscle volume loss (MVL) is observed in end-stage cancer patients as cachexia. However, the impact of MVL on tumor response and survival still remains unclear during chemotherapy in metastatic colorectal cancer (mCRC) patients. The aim of this study is to evaluate correlation between MVL and oncologic outcomes in mCRC patients. Methods: A total of 91 mCRC patients who received first-line chemotherapy were identified in our prospective registry between February 2007 and April 2013. Skeletal muscle index at the level of L3 vertebra (SMI) was calculated by muscle volume normalized by stature at the time of the induction of first-line chemotherapy (bSMI) and first evaluation of tumor response (fSMI). Patients whose SMI decreased more than 10% were classified as MVL group. The impact of these variables on oncologic outcomes (overall survival [OS], progression free survival [PFS], and tumor response rate [RR]) were analyzed. Results: Mean bSMI and fSMI were 35.0 (SD: 7.11) cm2/m2, and 34.2 (SD: 6.85) cm2/ m2, respectively. Eighteen patients were classified into the MVL group. The patients in MVL group significantly responded to the chemotherapy (RR of MVL: 11.1% vs. RR of non-MVL: 49.3%, p < 0.01). There was no significant difference in terms of high grade adverse effect between MVL and non-MVL group. Patients in MVL group had a significant shorter median PFS (MVL: 5.5 [2.5 - 10.1] months vs. non-MVL: 12.8 (3.8-80.5) months, p < 0.01) and median OS (MVL: 13.9 [6.2-61.2] months vs. non-MVL: 29.3 (8.2-94.0) months, p < 0.01). Multivariate analysis demonstrated that patients with MVL had significantly worse prognostic factor (OS: HR 3.51 [1.99-6.21], p < 0.01 and PFS: HR 8.27 [2.91-23.5], p < 0.01. Conclusions: The findings of this study suggested that MVL after the induction of the first line chemotherapy could be a novel predictive factor for chemotherapy response and prognosis. Further investigation should be required to clarify the mechanistic background.
