摘　　要：Objective: To identify the loss of heterozygosity (LOH) on chromosome 17p13 3 in ovarian cancer and cervical cancer Methods: The frequency of LOH on chromosome 17p13 3 in DNA samples from 24 ovarian cancers, 9 cervical cancers, and 13 non malignant gynecological diseases were determined respectively, using Southern blot method with probe PYNZ 22 Results: LOH on 17p13 3 was found in 12 of 24 (50 0%) ovarian cancers (including a borderline mucinous cystadenoma), 4 of 9 (44 4%) cervical carcinomas, and 1 of 13 (7 7%) non malignant gynecological diseases, which was cervical intraepithelial neoplasm III (CIN III) ( P< 0 01) Conclusion: These results show that LOH on 17p13 3 is associated with ovarian cancer and cervical cancer, suggesting that detection of LOH on 17p13 3 may be helpful to understand the molecular pathogenesis of ovarian cancer and cervical cancerObjective: To identify the loss of heterozygosity (LOH) on chromosome 17p13 3 in ovarian cancer and cervical cancer Methods: The frequency of LOH on chromosome 17p13 3 in DNA samples from 24 ovarian cancers, 9 cervical cancers, and 13 non malignant gynecological diseases were determined respectively, using Southern blot method with probe PYNZ 22 Results: LOH on 17p13 3 was found in 12 of 24 (50 0%) ovarian cancers (including a borderline mucinous cystadenoma), 4 of 9 (44 4%) cervical carcinomas, and 1 of 13 (7 7%) non malignant gynecological diseases, which was cervical intraepithelial neoplasm III (CIN III) ( P< 0 01) Conclusion: These results show that LOH on 17p13 3 is associated with ovarian cancer and cervical cancer, suggesting that detection of LOH on 17p13 3 may be helpful to understand the molecular pathogenesis of ovarian cancer and cervical cancer
