About

Pancreatic cancer is a highly lethal disease. The cause of pancreatic cancer is multifactorial. However, around 10% of cases are associated with hereditary predisposition. Germline mutations in BRCA1 and BRCA2, CDKN2A, STK11, DNA mismatch repair (MMR) genes (MLH1, MSH2, MSH6, or PMS2), PALB2, FANCC, FANCG, and ATM have been associated with an increased risk for pancreatic cancer. The prevalence of these germline mutations varies across populations. For instance, the prevalence of BRCA1/2 germline mutations in high-risk populations can be up to 20%. On the other hand, in unselected patient population, the prevalence of BRCA1/2 germline mutations is 5-7%. In Mexican population, data on the prevalence of BRCA1/2 germline mutations in patients with pancreatic cancer are lacking. Identification of BRCA germline mutations in patients with pancreatic cancer has implications for treatment. Also, it allows genetic testing and counselling for family members. This study will determine the prevalence of germline mutations associated with hereditary pancreatic cancer using a comprehensive gene panel in an unselected cohort of patients with pancreatic adenocarcinoma in Mexico.

Full description

This is an observational study to estimate the prevalence of germline mutations in patients with pancreatic cancer. Eighty four genes will be analyzed, all of which have been associated with hereditary cancer. The genes are included on Invitae Multi-Cancer Panel ®, performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology. The 84 genes include: AIP, ALK, APC, ATM, AXIN2, BAP1, BARD1, BLM, BMPR1A, BRCA1, BRCA2, BRIP1, CASR, CDC73, CDH1, CDK4, CDKN1B, CDKN1C, CDKN2A, CEBPA, CHEK2, CTNNA1, DICER1, DIS3L2, EGFR, EPCAM, FH, FLCN, GATA2, GPC3, GREM1, HOXB13, HRAS, KIT, MAX, MEN1, MET, MITF, MLH1, MSH2, MSH3, MSH6, MUTYH, NBN, NF1, NF2, NTHL1, PALB2, PDGFRA, PHOX2B, PMS2, POLD1, POLE, POT1, PRKAR1A, PTCH1, PTEN, RAD50, RAD51C, RAD51D, RB1, RECQL4, RET, RUNX1, SDHA, SDHAF2, SDHB, SDHC, SDHD, SMAD4, SMARCA4, SMARCB1, SMARCE1, STK11, SUFU, TERC, TERT, TMEM127, TP53, TSC1, TSC2, VHL, WRN, WT1.
