Objectives: Although the significance of skeletal muscle mass has been investigated in pancreatic cancer, there are no reports regarding the impact of skeletal muscle mass on prognosis in patients who have undergone second-line chemotherapy. We aimed to identify prognostic factors in patients with advanced pancreatic cancer treated with second-line FOLFIRINOX (folinic acid, fluorouracil, irinotecan, and oxaliplatin). Methods: We retrospectively reviewed the data of 57 pancreatic cancer patients treated with second-line FOLFIRINOX. Age, sex, body mass index, Eastern Cooperative Oncology Group (ECOG) performance status, carbohydrate antigen 19-9 levels, skeletal muscle area, skeletal muscle index (SMI), progression free survival (PFS), and overall survival (OS) were analyzed. Results: The median age of the 57 patients (male, 56.1%) was 60.4 years (38–78). Median PFS and OS were 2.6 and 6.6 months. On Kaplan-Meier curves, high SMI was associated with prolonged OS and PFS (P value = 0.003 and 0.015). In multivariate analysis, baseline SMI was significant independent prognostic factor in patients treated with second-line FOLFIRINOX. Conclusion: Baseline SMI has an impact on prognosis in patients who undergoing second-line chemotherapy for pancreatic cancer. Skeletal muscle mass may warrant consideration as a predictive factor with which to identify candidates for second-line chemotherapy for advanced pancreatic cancer.
