Negative Expression of DSG1 and DSG2, as Prognostic Biomarkers, Impacts on the Overall Survival in Patients with Extrahepatic Cholangiocarcinoma

Table 2

Comparison of DSG1 and DSG2 expression in normal tissue, adenoma, peritumoral tissue, and EHCC.

Tissue type	Number of patients (N)	DSG1 positive (%)	DSG2 positive (%)
EHCC	100	42 (42.0)	47 (47.0)
Peritumoral tissues	30	22 (73.7)	24 (80.0)
Adenoma	10	8 (80.0)	8 (80.0)
Normal tissues	15	15 (100.0)	15 (100.0)

DSG1: desmoglein 1; DSG2: desmoglein 2; EHCC: extrahepatic cholangiocarcinoma; compared to EHCC: , .
