Tezuka K, Ohgi K, Okamura Y, Sugiura T, Ito T, Yamamoto Y, Ashida R, Otsuka S, Todaka A, Uesaka K. The prognostic impact of ABO blood type in pancreatic cancer: Relevance to adjuvant chemotherapy. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2022; 29:922-931. [PMID: 35435311 DOI: 10.1002/jhbp.1152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 02/10/2022] [Accepted: 02/25/2022] [Indexed: 12/17/2023]
Abstract
BACKGROUND/PURPOSE The aim of this study was to investigate the prognostic impact of ABO blood type in resected pancreatic cancer (PC), with a focus on adjuvant chemotherapy. METHODS We retrospectively analyzed 510 patients who underwent pancreatectomy for PC between 2006 and 2017. Survival outcomes were investigated according to blood type and adjuvant chemotherapy regimen (S-1, gemcitabine, or no adjuvant chemotherapy). RESULTS Among the 510 patients, the overall survival (OS) of patients with blood type O was significantly better compared to those with blood type non-O (5-year OS rate, 46.6% vs 30.5%, P = .025). In 241 patients treated with adjuvant S-1, the 5-year OS of patients with blood type O was significantly better than those with blood type non-O (70.7% vs 44.2%, P = .001). Multivariate analysis showed that blood type non-O was an independent prognostic factor for OS in the overall cohort (hazard ratio [HR]: 1.58, P = .002) and in patients treated with adjuvant S-1 (HR: 2.99, P < .001). In patients treated with adjuvant gemcitabine or no adjuvant chemotherapy, there was no significant difference in OS between patients with blood type O and those with blood type non-O. CONCLUSIONS Blood type O predicted favorable survival in patients with resected PC, which was associated with adjuvant S-1.

ABO Blood Group and Risk of Pancreatic Carcinogenesis in Intraductal Papillary Mucinous Neoplasms. Cancer Epidemiol Biomarkers Prev 2021; 30:1020-1028. [PMID: 33653811 DOI: 10.1158/1055-9965.epi-20-1581] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Revised: 01/14/2021] [Accepted: 02/23/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND ABO blood group has been associated with risks of various malignancies, including pancreatic cancer. No study has evaluated the association of ABO blood group with incidence of pancreatic carcinogenesis during follow-up of patients with intraductal papillary mucinous neoplasms (IPMN). METHODS Among 3,164 patients diagnosed with pancreatic cysts at the University of Tokyo (Tokyo, Japan) from 1994 through 2019, we identified 1,815 patients with IPMN with available data on ABO blood group. We studied the association of ABO blood group with incidence of pancreatic carcinoma, overall and by carcinoma types [IPMN-derived carcinoma or concomitant pancreatic ductal adenocarcinoma (PDAC)]. Utilizing competing-risks proportional hazards models, we estimated subdistribution hazard ratios (SHR) for incidence of pancreatic carcinoma with adjustment for potential confounders, including cyst characteristics. RESULTS During 11,518 person-years of follow-up, we identified 97 patients diagnosed with pancreatic carcinoma (53 with IPMN-derived carcinoma and 44 with concomitant PDAC). Compared with patients with blood group O, patients with blood groups A, B, and AB had multivariable SHRs (95% confidence intervals) for pancreatic carcinoma of 2.25 (1.25-4.07; P = 0.007), 2.09 (1.08-4.05; P = 0.028), and 1.17 (0.43-3.19; P = 0.76), respectively. We observed no differential association of ABO blood group with pancreatic carcinoma incidence by carcinoma types. CONCLUSIONS In this large long-term study, patients with IPMN with blood group A or B appeared to be at higher risk of pancreatic carcinoma compared with those with blood group O. IMPACT ABO blood group can be a biomarker for pancreatic cancer risk among patients with IPMNs.
