Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The recurrent pancreatic cancer (Rec-PC) after radical surgery is sometimes eligible to clinical trial of chemotherapy for unresectable pancreatic cancer. However, the difference between Rec-PC and primary metastatic pancreatic cancer (PM-PC) did not know well. Thus, whether Rec-PC and PM-PC should be included in the same category when conducting clinical trials evaluating chemotherapy remains controversial. The purpose of this study is to investigate the difference of overall survival (OS) between Rec-PC and PM-PC, and analyze their impact on prognosis.

Intervention Type DRUG

Overall, data of 276 patients (144 men and 132 women, 224 Rec-PC and 51 PM-PC) were retrospectively analyzed. The median patient age was 70 (range; 29-91) years. Serum carbohydrate antigen (CA) 19-9 among Rec-PC group (median; 207 U/mL) and PM-PC group (median; 1680 U/mL) was statistically different. Rec-PC patients received gemcitabine plus nab-paclitaxel (106), S-1 (37), gemcitabine (22), FOLRIFINOX (18) and other (8) regimen as a first line chemotherapy. 67 Rec-PC patients underwent any local treatment. PM-PC patients received gemcitabine plus nab-paclitaxel (34), FOLRIFINOX (8), gemcitabine (5), S-1 (2) and other (2) regimen as a first line chemotherapy.
