[Results of several combination modalities for maxillary cancer].

Two hundred forty-six patients with the histologically proved squamous cell carcinoma of the maxillary sinus were treated at the Department of Radiology, National Sapporo Hospital, with various combined modes of surgery, irradiation and chemotherapy. Four combination modalities were used from 1966 to 1983. One hundred sixty-three (66.3%) patients were men and 83 (33.7%) were women. Five-year survival was 41.0% in T2 (16 cases), 22.3% in T3 (176 cases) and 15% in T4 (53 cases). In 72 cases treated since 1978 with tumor reduction as completely as possible, five-year survival was 43.5%. We recommand tumor reduction as complete as is possible and 40-50 Gy irradiation.

[Combined chemotherapy for head and neck cancer using cisplatin, methotrexate and continuous subcutaneous infusion of peplomycin].

Twenty-one patients with advanced or recurrent squamous cell carcinoma of the head and neck were treated with cisplatin, methotrexate and continuous subcutaneous infusion of peplomycin. The overall response rate was 62% (13/21) with 19% (4/21) complete response. The median duration of partial response was 2 months, while that of complete response was 3 months. Toxic effects were acceptable with no fatalities, but nephrotoxicity (33%), leukocytopenia (24%), thrombocytopenia (29%) and severe nausea and vomiting (76%) occurred. Pulmonary toxicity due to continuous subcutaneous infusion of peplomycin (15 mg/day, 4 days) was not seen.

[Multiple primary cancer and radiation-induced cancer of the uterine].

This report is concerned with multiple primary cancers developing in invasive uterine cancer. Second primary tumors were recorded 27 women with a total of 30 non-uterine cancer (exception of radiation-induced cancer). 17 patients of radiation-induced neoplasm were observed (Rectal cancer 4, soft part sarcoma 4, cancer of urinary bladder 3, bone tumor 3, uterine cancer 2 and cancer of Vulva 1). One case is 4 lesions (corpus, sigma, thymoma and stomach), 2 cases are 3 lesions (uterine cervix, stomach and maxillary sinus: uterine cervix, thyroidal gland and radiation-induced soft part sarcoma). Only 5 of these 17 patients were known irradiated dose (50 Gy approximately 55 Gy), however others unknown. The mean latent periods of 17 cases of radiation induced neoplasms are 19.4 years. 16 patients of late second cancers of the cervix appearing from 11 to 36 years (average 19.5 years) after initial radiotherapy were recorded.

Interstitial irradiation for carcinoma of tongue complicated by chronic renal failure undergoing hemodialysis--a case report.

There has been some controversy concerning dose-time correction in continuous irradiation at low dose rates. We present the results of carcinoma of the tongue in a patient complicated by chronic renal failure, for which he was undergoing hemodialysis three times a week. This patient was treated with a single implant but with a doubling of 137Cs needles for double strength. The actual dose was given in a shorter treatment time than recommended, with the dose-time adjustment following the Paterson-Parker system. The patient has been alive and well for eight years.
