CHANGES OF SKELETAL MUSCLE MASS DURING PALLIATIVE CHEMOTHERAPY IN OLDER PATIENTS WITH ADVANCED GASTRIC CANCER

Abstract Background The mortality rate of patients with unresectable gastric cancer (UGC) has decreased with the development of chemotherapies and surgical techniques. However, the survival rate remains low. We retrospectively examined the prognostic significance of the pretreatment skeletal muscle mass index (SMI) and nutritional and inflammatory factors in patients with UGC. Methods This study included 83 patients diagnosed with UGC at Tottori University Hospital who received palliative chemotherapy based on 5-fluorouracil. Pretreatment computed tomography (CT) measured overall skeletal muscle mass (SMM) and cross-sectional SMM at the third lumbar vertebra (L3). We focused on the neutrophil-to-lymphocyte ratio (NLR), C-reactive protein-to-albumin ratio (CAR), prognostic nutritional index (PNI), and platelet-to-lymphocyte ratio (PLR) as nutritional and inflammatory factors. Results Receiver operating characteristic curve analysis was performed for median survival time (MST) after palliative chemotherapy. SMIs for males and females (43.9 cm2/m2 and 34.7 cm2/m2, respectively) were the cutoff values, and patients were divided into high (SMIHigh; n = 41) and low SMI groups (SMILow; n = 42). Body mass index (BMI) was significantly higher in patients in the SMIHigh group than in the SMILow group (p < 0.001). The number of patients who received third-line chemotherapy was significantly higher in the SMIHigh group than in the SMILow group (p = 0.037). The MST was significantly higher in the SMIHigh group than in the SMILow group (17.3 vs. 13.8 months; p = 0.008). The incidence of grade 3 or 4 side effects was significantly higher in patients with SMILow UGC (p = 0.028). NLR was significantly higher in patients with SMILow than it was in those with SMIHigh. (p = 0.047). In the univariate analysis, performance status, SMI, histological type, lines of chemotherapy, and NLR were prognostic indicators. The multivariate analysis identified SMI (p = 0.037), NLR (p = 0.002), and lines of chemotherapy (p < 0.001) as independent prognostic factors. Conclusions The SMILow group had significantly more grade 3 or 4 side effects, were related to high NLR, and had a significantly worse prognosis than the SMIHigh group.

Poor Prognostic Factor

Abstract Cancer causes muscle mass loss, which is associated with a poor prognosis. Chemotherapy may also reduce muscle mass. We investigated skeletal muscle mass change during palliative chemotherapy for advanced gastric cancer (AGC) and its association with treatment outcomes. We retrospectively reviewed 111 consecutive AGC patients who underwent first-line palliative chemotherapy. Skeletal muscle area was measured before and after chemotherapy at the third lumbar vertebra level using computed tomography scans. We compared skeletal muscle index (SMI), body mass index (BMI), and body weight changes to chemotherapy response and survival. The 80 male and 31 female patients’ median age was 65 (range 31–87) years, and 46.8% had sarcopenia at baseline. Median pre-chemotherapy to post-chemotherapy SMI, BMI, and body weight decreases were − 4.5 cm2/m2 (− 11.3%) (P < 0.001); − 0.7 kg/m2 (− 3.2%) (P < 0.001); and − 2.0 kg (− 3.5%) (P < 0.001), respectively. Median SMI decreases for patients with objective response, stable disease, and disease progression were − 4.0 cm2/m2 (range − 20.1 ~ 9.5); − 4.5 cm2/m2 (range − 19.8 ~ 0.8); and − 3.8 cm2/m2 (range: − 17.6 ~ 0.1), respectively. Response to chemotherapy was not associated with SMI decrease (P = 0.463). In multivariable analysis, sarcopenia at baseline (HR 1.681; 95% CI 1.083–2.609, P = 0.021), decreased SMI (HR 1.620; 95% CI 1.041–2.520; P = 0.032) were significant poor prognostic factors for survival. Skeletal muscle mass decreased significantly during chemotherapy in AGC patients, but was not associated with chemotherapy response. Decreased SMI was a poor prognostic factor in AGC patients during first-line palliative chemotherapy.

Background Although low skeletal muscle mass has an adverse impact on the treatment outcomes of cancer patients, whether the relationship between preoperative skeletal muscle mass and gastrectomy outcomes in gastric cancer (GC) differs between men and women is unclear. The study aimed to clarify this relationship based on gender. Methods Between January 2007 and December 2015, 1054 patients who underwent gastrectomy for GC at Osaka City General Hospital were enrolled in this study. We evaluated sarcopenia by the skeletal muscle index (SMI), which was measured by computed tomography (CT) using areas of muscle in the third lumbar vertebral body (L3). Male and female patients were each divided into two groups (low skeletal muscle and high skeletal muscle). Results The SMI emerged as an independent predictor of 5-year overall survival (OS) in male GC patients (Hazard ratio 2.51; 95% confidence interval (CI) 1.73–3.63, p < 0.001) based on multivariate analysis. However, this index was not an independent predictive determinant of 5-year cancer-specific survival (CSS). The SMI was not an independent predictor of either OS or CSS in female GC patients. The incidence of leakage and major complication (Clavien Dindo grade ≧ 3) did not differ significantly across groups. Conclusions Preoperative skeletal muscle mass is a valuable prognostic predictor of OS in male GC patients.
