The preoperative cachexia index predicts outcomes after pancreatic resection for resectable pancreatic cancer
摘要
The cachexia index (CXI) is a numerical measure of cachexia, calculated based on the skeletal muscle area and blood test values. However, the relationship between the preoperative CXI levels and pancreatic cancer prognosis has not been investigated.
MethodsThis retrospective study included 310 patients who underwent resection of resectable pancreatic cancer. We investigated the impact of CXI-low levels on the disease-free survival (DFS) and overall survival (OS) of patients following pancreatic resection for resectable pancreatic cancer.
ResultsThere were 121 (42%) and 167 (58%) patients enrolled in the CXI-low and CXI-high groups, respectively. Multivariate analyses of the prognostic factors identified that CXI-low was an independent predictor of both DFS (hazard ratio [HR] 2.08, p < 0.01) and OS (HR 2.33, p < 0.01). In the CXI-low group, the time to recurrence was shorter (p < 0.01) and the initial treatment at recurrence was more difficult to initiate (p = 0.03). Similarly, for patients with neoadjuvant chemotherapy, CXI-low was an independent predictor of DFS (HR 3.73, p < 0.01) and OS (HR 16.9, p < 0.01).
ConclusionPreoperative CXI-low can be a significant prognostic factor for poor DFS and OS of patients with resectable pancreatic cancer. These results suggest that preoperative cancer cachexia influences the intensity of postoperative treatment.
