Chromosomal numerical aberrations in gastric carcinoma: analysis of eighteen cases using in situ hybridization.

Paraffin-embedded tumor cells of 18 cases of gastric carcinoma were hybridized with digoxigenin-labeled repetitive DNA probes specific for the centromeric regions of chromosomes X, Y, 1, 2, 3, 4, 6, 7, 8, 9, 10, 11, 12, 15, 16, 17, 18, and 20. All cases demonstrated numerical chromosomal aberrations. The most exciting aberration, polysomy (five or more copies) of several chromosomes, was found in all cases except a case of mucinous adenocarcinoma, which showed trisomy 9 as the sole chromosomal numerical aberration.

Ovarian serous cystadenoma associated with Sertoli-Leydig cell tumor--a case report.

We Describe a case of ovarian serous cystadenoma having Sertoli-Leydig cell tumor, well differentiated, in the cystic septum. Well differentiated Sertoli-Leydig cell tumor coexisting with other tumor, including serous tumor, has not yet been described. In all cases of Sertoli-Leydig cell tumor with heterologous components or other tumors, the androblastomatous components are intermediately or poorly differentiated.

Multimodal treatment for the locally advanced stage IB, IIA, IIB patients of cervical cancer.

By employing neoadjuvent chemotherapy (NCT) before radical hysterectomy (RS) and pelvic radiotherapy (RT) in bulky locally advanced cervical cancer (IB, IIA, IIB), the study was focused to update the results of the author's therapeutic experience with multimodal treatment by observing tumor free survivals along with related prognostic factors in different treatment modalities with NCT. The chemotherapy regimen for induction is composed of Vinblastin, Bleomycin and cis-Platin regimen (VBP). The effect of neoadjuvent chemotherapy was evaluated by the WHO definition of clinical response (CR, PR, ST, PG).
