Objective: To screen LKB1 mutation in sporadic colon and ovarian tumors. Methods: Using PCR-SSCP analysis, 72 colon cancer, 45 ovarian cancer, 14 granulosa cell tumor were screened for LKB1 mutation. Results: no mutation was in sporadic colon and ovarian adenocarcinomas. Two mutations were detected in one of the granulosa cell tumors: a mis-sense mutation affecting the putative start codon (ATG?ACG, MIT); and a silent change in erxon 7 (CTT?CTA, leucine). Conclusion: LKB1 mutations in sporadic colon and ovarian cancers are rare event and LKB1 is not the target gene lost on chromosome 19p13.3 in ovarian cancers.

Two mutations were detected in one of the granulosa cell tumors: a mis-sense mutation impact the putative start codon (ATG® ACG, MIT); and a silent change in erxon 7 (CTT® CTA, leucine). Conclusion: LKB1 mutations in sporadic colon and ovarian cancers are rare events and LKB1 is not the target gene lost on chromosome 19p13.3 in ovarian cancers.
