Evaluation of 1p Losses in Primary Carcinomas, Local Recurrences and Peripheral Metastases from Colorectal Cancer Patients

Abstract excerpt

Cytogenetic and molecular genetic analyses of colorectal adenomas and carcinomas have shown that loss of the distal part of chromosome arm 1p is common, particularly in tumors of the left colon. Because the importance of 1p loss in colorectal cancer metastases is unknown, we compared the frequency, exact site and extent of 1p deletions in primary carcinomas (n=28), local recurrences (n=19) and metastases (n=33)...
