Consensus in determining the resectability of locally progressed pancreatic ductal adenocarcinoma – results of the Conko-007 multicenter trial

Table 1 Judgement of resectability by 5 independent surgeons

	Surgeon A		Surgeon B		Surgeon C		Surgeon D		Surgeon E
	[n]	[%]	[n]	[%]	[n]	[%]	[n]	[%]	[n]	[%]
R0 Resection Possible	6	3.1	16	8.1	12	7.5	3	1.6	3*	1.5
R0 Resection Questionable	43	22.2	35	17.7	32	20.1	19	9.9	14	7.1
R0 Resection Impossible	145	74.7	147	74.2	115	72.3	170	88.5	181	91.4
Cases without evaluation of resectability	6		2		41		8		2

Surgeons evaluated the local resectability of progressed pancreatic cancer. They classified the case (n) into R0 resection possible for resectable cases, R0 resection impossible for locally advanced cases and R0 resection questionable for borderline resectable cases. Significant deviations in judgement were observed with surgeon E matching significantly less cases as resectable (χ² frequency distribution with post hoc analysis by cellwise adjusted residuals * P < 0.05)
