Long term survivors with metastatic pancreatic adenocarcinoma treated with gemcitabine: a retrospective analysis

Table 5 Response rates and correlation with survival according to CT scans and CA 19-9.

	Responses (%)	Median OS responders	Median OS Non-responders	p value
CT scans	5 (25%)	24 mo	18.8 mo	0.66
CA 19-9	12 (63%)	20.5 mo	26.9 mo	0.45

CT scans = Computerized Tomography scans; Median OS = Median Overall Survival; mo = months. CT scan responses are based on modified WHO criteria. CA 19-9 responses were determined by a 50% drop in the baseline CA19-9 value. p value = level of significance.
