Abstract:
Objective:To investigate the clinicopathological characteristics and prognostic factors of pancreatic cancer patients with liver metastasis.Methods:The clinical data of 67 pancreatic cancer patients with liver metastases who received first treatment in Department of Oncology of the First Affiliated Hospital of Naval Medical University between July 2012 and June 2016 were retrospectively analyzed. The relationship between patient survival time and the clinicopathological characteristics including patients' age, gender, tumor location, physical activity status score, tumor markers, number of distant metastatic organs, radiotherapy at the primary site, first-line chemotherapy regimen, number of cycles of first-line chemotherapy received, and liver metastases undergoing transcatheter arterial chemoembolization (TACE) was analyzed. Kaplan-Meier curves were plotted to reveal survival time in pancreatic cancer patients with liver metastases, and univariate and multifactorial COX proportional risk regression models were used to analyze independent prognostic risk factors for pancreatic cancer patients with liver metastases.Results:All patients were followed up until December 31, 2018, and all 67 patients died. The results of univariate analysis showed that patients with positive tumor marker, number of distant metastatic organs ≥2, number of cycles of first-line chemotherapy ≤2, no radiotherapy to the primary site and no TACE had shorter survival than those with negative tumor marker, one distant metastatic organ, number of cycles of first-line chemotherapy ≥3, with radiotherapy to the primary site and TACE, and all the differences were statistically significant (all P values <0.05). The results of multifactorial analysis showed that positive tumor markers ( HR=0.567, 95% CI 0.332-0.954, P=0.031), number of distant metastatic organs ≥2 ( HR=0.581, 95% CI 0.353-0.977, P=0.039), number of first-line chemotherapy cycles ≤2( HR=1.890, 95% CI 1.155-3.121, P=0.013) and primary foci without radiotherapy ( HR=0.414, 95% CI 0.231-0.732, P=0.002) were the independent prognostic risk factors for pancreatic cancer patients with liver metastasis. Conclusions:The prognosis of pancreatic cancer patients with liver metastasis is affected by multiple factors, among which positive tumor markers, more distant metastatic organs, no radiotherapy at the primary site and fewer first-line chemotherapy cycles are independent prognostic risk factors for pancreatic cancer with liver metastasis.
