Baseline Sarcopenia and Skeletal Muscle Loss During Chemotherapy Affect Survival Outcomes in Metastatic Gastric Cancer

4025 Background: We showed in a previous work that “Patient Generated-Subjective Global Assessment” (PG-SGA) was independently associated with survival and treatment toxicities in non-pretreated metastatic colorectal cancer (mCRC) patients. We have evaluated here if muscle mass in these patients can provide useful additional information for clinical practice. The objective of the present work was to evaluate the association between baseline sarcopenia, and the variation of the Skeletal Muscle Index (SMI) under treatment with survival and chemotherapy-related toxicities in our population of non-pretreated mCRC patients. Methods: This prospective multicenter observational study enrolled non-pretreated mCRC patients. Measurement of SMI was performed on routine CT scan at day 0 (D0) and day 60 (D60). PG-SGA score and other nutritional factors were collected at D0. Progression-free survival (PFS) and overall survival (OS) were calculated from treatment start. Treatment related toxicities were registered according to the NCI CTCAE v4.0. Results: 149 patients were included in eight French centers from 7/2013 to 11/2016. Sarcopenia at baseline was not significantly associated with survival outcomes or chemotherapy-related toxicities. The best cut-point value of SMI variation (between D0 and D60) for OS prediction obtained with a log-rank maximisation method was -14%. The decrease in SMI > 14%, with a median follow-up of 23 months, was significantly associated with shorter PFS (6 vs 9 mo; HR 1.8, 95%CI 1.1-3.1, p = 0.02) and OS (8.5 vs 26 mo; HR 2.4, 95%CI 1.3-4.4, p = 0.004), independently of hypoalbuminemia and malnutrition defined by PG-SGA, in multivariate analysis. 40% of patients with a SMI decrease > 14%, and 22% of patients with a SMI increase or stable or decrease < 14% developed grade ≥ 2 clinical toxicities (OR 3.0, 95%CI 1.2-7.7, p = 0.02), but the difference was not statistically significant in multivariate analysis (OR 2.3. 95%CI 0.8-6.7, p = 0.1). Conclusions: To our knowledge, this study is the first study assessing the association of skeletal muscle loss with survival and treatment toxicities in patients with mCRC prospectively. In our population of non pre-treated mCRC patients, baseline sarcopenia was not associated with poor survival outcomes, but the decrease in SMI > 14% during the first two months of treatment was significantly associated with decreased PFS and OS, independently of other prognostic and nutritional factors.

Abstract Background Patients with gastric cancer have an increased nutritional risk and experience a significant skeletal muscle loss after surgery. We aimed to determine whether muscle loss during the first postoperative year and preoperative nutritional status are indicators for predicting prognosis. Methods From a gastric cancer registry, a total of 958 patients who received curative gastrectomy followed by chemotherapy for stage 2 and 3 gastric cancer and survived longer than 1 year were investigated. Clinical and laboratory data were collected. Skeletal muscle index (SMI) was assessed based on the muscle area at the L3 level on abdominal computed tomography. Results Preoperative nutritional risk index (NRI) and postoperative decrement of SMI (dSMI) were significantly associated with overall survival (hazards ratio: 0.976 [95% CI: 0.962–0.991] and 1.060 [95% CI: 1.035–1.085], respectively) in a multivariate Cox regression analysis. Recurrence, tumor stage, comorbidity index were also significant prognostic indicators. Kaplan-Meier analyses exhibited that patients with higher NRI had a significantly longer survival than those with lower NRI (5-year overall survival: 75.8% vs. 63.0%, P < 0.001). In addition, a significantly better prognosis was observed in a patient group with less decrease of SMI (5-year overall survival: 75.7% vs. 66.2%, P = 0.009). A logistic regression analysis demonstrated that the performance of preoperative NRI and dSMI in mortality prediction was quite significant (AUC: 0.63, P < 0.001) and the combination of clinical factors enhanced the predictive accuracy to the AUC of 0.90 (P < 0.001). This prognostic relevance of NRI and dSMI was maintained in patients experiencing tumor recurrence and highlighted in those with stage 3 gastric adenocarcinoma. Conclusions Preoperative NRI is a predictor of overall survival in stage 2 or 3 gastric cancer patients and skeletal muscle loss during the first postoperative year was significantly associated with the prognosis regardless of relapse in stage 3 tumors. These factors could be valuable adjuncts for accurate prediction of prognosis in gastric cancer patients.

Abstract Background: Patients with gastric cancer have increased nutritional risk and experience a significant skeletal muscle loss after surgery. We aimed to determine whether muscle loss during the first postoperative year and nutritional status are indicators for predicting prognosis. Methods: From a gastric cancer registry, a total of 958 patients who received curative gastrectomy followed by chemotherapy for stage 2 and 3 gastric cancer and survived longer than 1 year were investigated. Clinical and laboratory data were collected. Skeletal muscle index (SMI) was assessed based on the muscle area at the L3 level on abdominal computed tomography. Results: Preoperative nutritional risk index (NRI) and postoperative decrement of SMI (dSMI) were significantly associated with overall survival (hazards ratio: 0.972 [95% CI: 0.958-0.986] and 1.058 [95% CI: 1.033-1.085], respectively) in a multivariate Cox regression analysis. Recurrence, tumor stage, comorbidity, and the preoperative muscle and subcutaneous fat area were also significant prognostic indicators. Kaplan-Meier analyses exhibited that patients with higher NRI had a significantly longer survival than those with lower NRI (3-year overall survival: 84.6% vs. 72.9%, P < 0.001). In addition, a significantly better prognosis was observed in a patient group with less decrease of SMI (3-year overall survival: 85.6% vs. 74.5%, P = 0.009). A logistic regression analysis demonstrated that the performance of preoperative NRI and dSMI in mortality prediction was quite significant (AUC: 0.63, P < 0.001) and the combination of clinical factors enhanced the predictive accuracy to the AUC of 0.90 (P < 0.001). This prognostic relevance of NRI and dSMI was maintained in patients experiencing tumor recurrence. Conclusions: Skeletal muscle loss during the first postoperative year and preoperative NRI are predictors of overall survival in stage 2 or 3 gastric cancer patients regardless of relapse. Our results support the potential importance of exercise and nutritional support along with standard treatment.
