Cytogenetic analysis of short-term cultures from 105 squamous cell carcinomas of the larynx (LSCC) revealed clonal chromosome aberrations in 56 tumors. Simple karyotypic changes (less than four aberrations per clone) were found in 24 cases, and the remaining 32 tumors had complex karyotypes with mul

β¦ Synopsis
Cytogenetic analysis of short-term cultured cells from a urethral squamous cell carcinoma showed the tumor to have an abnormal, karyotypically complex near-diploid clone as well as its near-tetraploid duplicate. This is the first urethral carcinoma with chromosomal abnormalities to be reported. Chromosomes Y, 2, 3, 4, 6, 7, 8, 11, and 20 were all involved in numerical and/or structural rearrangements. Of particular interest was the fact that no rearrangements of chromosomes 9 and 17, both almost ubiquitously involved in transitional cell carcinoma of the urinary tract, were seen.

Background and Methods. Sixty patients were treated with radiation therapy alone (56 patients) or followed by surgery (4 patients) between 1970 and 1995 for squamous cell carcinoma of the nasal vestibule. Results. Local control rates at five years after irradiation alone in 56 patients were: T1-T2,
