ABSTRACT
OBJECTIVE: Comparative genomic hybridization (CGH) is a new fluorescence in situ hybridization (FISH) technique to identify genomic aberrations in cancers. The purpose of this study was to analyze non-random chromosomal DNA aberrations involved in cervical squamous cell carcinoma cell lines from Korean women. METHODS: We analyzed non-random chromosomal DNA aberrations involved in cervical squamous cell carcinoma cell lines from Korean women, SNU-17, SNU-682, and SNU-902 using CGH. RESULTS: Chromosomal DNA gains of 5p, 5q22-q23, 8q11.2-q12, 14q21-qter, and 20 as well as chromosomal DNA losses of 21 were found frequently. Chromosomal DNA gains on chromosome 3q, 6P, 7p13-pter, 9p22-pter, 9q21-qter, 15q21-q22, 17q22-qter, 18p11.3-pter, 18q11.2-q21, 19p13.3-pter, 19q13.2-q13.3, and 22q12-qter, with losses on 4p14-pter, 10p11.2-p13 and 10q24 were observed in 2 of 3 cell lines. CONCLUSION: Non-random aberrations which were disclosed in this study might be candidate regions for the abnormal genes involved in the tumorigenesis of cervical squamous cell carcinomas. Datas about chromosomal aberrations of Korean squamous cell carcinoma cell lines in this study could afford very useful basic information for the development of diagnostic and therapeutic modalties targeting the abnormal genes associated with uterine cervical cancer in Korea.

OBJECTIVE: We have attempted to identify prognostic factors regarding CC/hMG ovarian stimulation and IUI in infertility and to seek factors valuable in planning infertility treatment and predicting the success rate of IUI therapy in individual couples. METHODS: The variables selected for initial analysis were female age, duration of infertility, type and diagnosis of infertility, number of pre-ovulatory follicles (>or=16 mm, >or=18 mm follicles), thickness of the endometrium, number of the treatment cycles, result of semen analysis, ovarian stimulation protocol, number of IUI. A logistic regression method was used to identify significant variables that contribute to the success of CC/hMG/IUI treatment. RESULTS: Logistic regression analysis revealed four predictive variables as regards pregnancy: duration of infertility (p=0.011), infertility etiology (p=0.049), number of IUI (p=0.004), method of ovarian stimulation (p=0.042). A cause of infertility, especially ovarian dysfunction other than tubal factor, a shorter duration of infertility (<6 years) and CC/hMG minimal ovarian stimulation protocol with double IUI resulted in better treatment success in CC/hMG with IUI cycles. CONCLUSION: We concluded that careful patient selection criteria coupled with successful ovarian stimulation and increased sperm count in female reproductive tract is the model for CC/hMG/IUI sucess.
