Malignant lymphoma of the sinus is very rare but potentially radiocurable neoplasm. The disease is tend to be localized to the sinus and spread to adjacent local structure on initial presentation, and change to generalized lymphoma is uncommon. Most of sinus lymphoma is diffuse histiocytic type. Radiotherapy to the primary and neck nodes is the treatment of choice, and a...

In order to clarify the effect of radiation on the mouse jejunal crypt cells by combined administration of adriamycin and radiation and also to evaluate the enhancing effect of adriamycin, the authors performed this study by delivering single irradiation of 1,000 to 1,600 rad to the whole abdomen of mice by cobalt-60 teletherapy unit. In combination with adriyamycin treatment groups,...

From 1979 to 1984, 39 local allograft irradiations were given to 29 patients: 10 irradiations were administered for prevention and 29 for reversal of acute rejection of transplanted kidney. Three doses of 150 cGy every other day were combined with high-dose of methylprednisolone pulse (1 gm/day) for 3 days. For prevention of acute rejection, local irradiation was delivered on the...

From 1970 to 1982, thirty one patients with malignant tumors of the parotid gland were treated with radiation therapy at department of Radiation Oncology, Yonsei University College of Medicine, Yonsei Cancer Center. Indication for radiotherapy were as follows: 1) when there were microscopic or gross residual diseases (6 patients), 2) when patients considered to have high risk factors (15 patients),...

Thirty-six patients with carcinoma of the tonsillar region treated with radical radiotherapy at Yonsei Cancer Center between Jan. 1971 and Dec. 1980 were retrospectively reviewed. The purpose of this study is to evaluate the clinical characteristics and the treatment results. Seventy-five per cent of patients were in advanced stage when they were first seen. Incidence of nodal involvement at the time...

Sixty patients with head and neck carcinoma were studied retrospectively to assess the impact of treatment on survival and local control rate by stage in the Dept of Radiation Therapy, Korea University Had Wha Hospital between March 1981 and March 1986. Prior to definite radiotherapy, patients were evaluated by physical examination and radiologic studies including hest, paryngogram and CT scan...

RTOG proposed a multivariate modeling system predicting the response of head and neck cancers to radiation therapy in 1984. The aim of this study was to verify whether PPC (Probability of primary clearance calculated by a multivariate modeling system) had any correlation with the survival in the patients with carcinoma of the nasopharynx following radiation therapy. Analysing 81 patients with...

From Nov. 1983 through Jan. 1986, 43 patients with nonsmall cell lung cancer were treated by radiation therapy at Inje Medical College Paik Hospital. 38 patients were available for the analysis of this study. 33 patients received definite irradiation with curative intent, while 5 patients received postoperative irradion. Chemotherapy was added in 12 patients before, during and after radio-therapy. 28...

The malignant small round cell tumor of the thoracopulmonary region was described by Askin in 1979 and called as Askin Tumor. The Askin tumor is a rare, arises from the soft tissues of the chest wall or peripheral lung which is predominantly in younger generation. Clinical and pathologic appearance were very similar to Ewing's sarcoma and rhabdomyosarcoma but when examined...

To access the result of radiation therapy for 8 years experiences, 21 patients who were treated with superior vena cava syndrome had been analysed according to dose fractionation and toal dose. The results are as follows; 1. In high fractionate dose group, six of eleven patients (54.5%) exhibited relief of symptoms in 1-2 days, and additional three patients of nine (81.7%)...

Heterotopic bone formation is a complication which occurs in 0.6 to 61.7% of patients after total hip replacement arthroplasty. We reviewed 4 patients (8 hips) who received postoperative irradiation on their hips for prevention of heterotopic bone formation in the Department of Therapeutic Radiology, Seoul National University Hospital from January 1981 through August 1985. Radiation therapy was started 6 to...
