Genetic abnormalities were assessed in 56 benign, low-, and high-grade ovarian tumors using comparative genomic hybridization (CGH) and analysis of loss of heterozygosity (LOH). In addition, 95 epithelial tumors were analyzed for microsatellite repeat instability. DNA sequence copy number abnormalities (CNAs) were not detected in the benign tumors, and more(More)
We have been performing PDT using Excimer Dye Laser (EDL) or YAG-OPO laser, a type of low power laser, both of which have a considerably higher degree of tissue penetration even when compared to PDT using Argon Dye Laser (ADL).PDT is a relatively simple procedure without any bleeding and does not require anesthesia since it causes no pain. PDT is performed(More)
Comparative Genomic Hybridization (CGH) is a powerful new method which allows genome-wide mapping of regions with DNA sequence copy number changes (both increases and decreases) in a single experiment without previous knowledge of the locations of the regions of abnormality. CGH is based on in situ hybridization of differentially labeled total genomic tumor(More)
The incidence of carcinoma in situ (CIS) and dysplasia of the uterine cervix has been increasing among young women in recent years. Most of these patients want to preserve their fertility. Also, to accommodate high-risk patients with complications, elderly patients, and those who refuse surgery, we perform PDT as a method to preserve fertility. The(More)
Genetic abnormalities were detected by comparative genomic hybridization (CGH) in 12 ovarian clear cell adenocarcinomas. DNA sequence copy number abnormalities (CNAs) occurring in more than 20% of the cancers included increased copy numbers of 8q11-q13, 8q21-q22, 8q23, 8q24-qter, 17q25-qter, 20q13-qter and 21q22-qter and reduced copy numbers of 19p.(More)
A new cell line, designated TMCC-2, has been established from operation material from a woman with endometrial clear cell carcinoma. TMCC-2 was successively subcultured 40 times in about 1 year. The monolayer culture cell showed a pavement-like arrangement of polygonal and short spindle-shaped cells, and had a tendency to pile-up without contact inhibition.(More)
One of the most important clinical issues in cancer chemotherapy is the presence of intrinsic resistance or the appearance of acquired resistance against chemotherapy. As for intrinsic resistance, we had to perform direct chemo-sensitivity testing, or had to rely on the knowledge empirically acquired from randomized clinical trials. However, molecular or(More)
We established new cell line designed TMCC-2.U, which suggested transformation to undifferentiated carcinoma, derived from endometrial clear cell carcinoma cell line (TMCC-2). The monolayer culture cell showed a pavement arrangement and spindle like shape. A rough-endoplasmic reticulum, mitochondria etc. are well developed. But cytoplasmic endocrine(More)
Serum levels of cancer-associated antigen 72-4 (CA72-4) (tumor-associated glycoprotein 72; TAG-72) from 106 patients with primary ovarian cancer were measured by an immunoradiometric assay employing the monoclonal antibodies (MAbs) B72.3 and CC49. Immunohistochemical localization of TAG-72 was also investigated using immunoperoxidase methodology in(More)
