Purpose:
Cancer cachexia (CC) is commonly seen in advanced lung cancer patients and associated with poor prognosis. However, little is known about CC that develops during chemotherapy. We evaluated the prognostic impact of CC and skeletal muscle wasting that develops during the course of chemotherapy in advanced non-small cell lung cancer (NSCLC) patients.
Methods:
The clinical data of 134 newly diagnosed NSCLC patients were retrospectively reviewed. CC was defined as a body weight loss >5 or >2 % in patients with a body mass index of <20 kg/m(2). CC was assessed at baseline (T1) and 3 months (T2), 6 months (T3), and 12 months (T4) after chemotherapy initiation. Skeletal muscle mass was assessed using the lumber skeletal muscle index (LSMI).
Results:
The proportion of patients with CC at T1, T2, T3, and T4 was 45.6, 46.1, 25.5, and 26.0 %, respectively. The frequency of grade 3 chemotherapy-induced anorexia was higher in patients with CC than those without CC at T2 (15.4 vs. 0.0 %, P = 0.0044). At all time points, patients with CC had shorter survival times than those without CC. Patients with low LSMIs (men, <41 cm(2)/m(2); women, <38 cm(2)/m(2)) tended to have poor prognosis. Adjusted Cox proportional hazard ratios and corresponding confidence intervals for CC at T1, T2, T3, and T4 were 2.53 (1.33-4.88), 1.97 (1.27-3.06), 3.86 (2.14-6.81), and 1.62 (0.80-3.16), respectively.
Conclusion:
CC presence and decreased skeletal muscle mass are associated with poor prognosis in advanced NSCLC patients receiving chemotherapy.
