Analysis of a Systemic Inflammatory Biomarker in Advanced Bile Tract Carcinoma Treated with Anti-PD-1 Therapy: Prognostic and Predictive Significance of Lung Immune Prognostic Index Score

Table 2

Relationship between LIPI groups and response to anti-PD-1 treatment.

Best overall response	No. of patients (%)			value
	Overall	The good LIPI	The intermediate/poor LIPI
CR	2 (1.8)	1 (2.6)	1 (1.4)	1
PR	16 (14.5)	8 (21.1)	8 (11.1)	0.160
SD	62 (56.4)	24 (63.2)	38 (52.8)	0.297
PD	30 (27.3)	5 (13.2)	25 (34.7)	0.016
Objective response	18 (16.4)	9 (23.7)	9 (12.5)	0.132
Disease control rate	80 (72.7)	33 (86.8)	47 (65.3)	0.016

LIPI: lung immune prognostic index; PD-1: programmed cell death-1; CR: complete response; PR: partial response; SD: stable disease; PD: progressive disease.
