Clinical stage IE primary lymphoma of the nasal cavity: radiation therapy and chemotherapy.

Purpose: To determine the appropriate radiation therapy and chemotherapy for primary lymphoma of the nasal cavity to improve the local control and survival rates.

Materials And Methods: Of the 25 adult patients with stage IE nasal lymphoma, nine underwent local radiation therapy alone and 16 underwent radiation therapy and chemotherapy (intravenous infusion). Radiation doses to the involved area were 22-54 Gy (median dose, 49 Gy).

Treatment for non-Hodgkin's lymphoma (stage I, II) of the elderly: usefulness of local and regional irradiation and reduced dose chemotherapy.

Purpose: To examine the usefulness and safety of a new treatment regimen consisting of irradiation to the involved area and adjacent lymph node area, and reduced dose chemotherapy for elderly patients with non-Hodgkin's lymphoma.

Methods And Materials: The core of this study was 38 elderly patients older than 65 years old with intermediate or high grade non-Hodgkin's lymphoma, and concomitantly suffering from some other geriatric disease. They received involved area irradiation (40 Gy), adjacent lymph node irradiation (30 Gy), and reduced dose chemotherapy (two cycles of 50-70% ACOP: Doxorubicin, Cyclosphosphamide, Vincristine, Prednisone or 70% MACOP-B: Doxorubicin, Cyclophosphamide, Vincristine, Methotrexate, Bleomycin, Prednisone for 4 weeks).

Is postoperative radiotherapy for thymoma effective?

Objective: The authors determined the effect of postoperative mediastinal irradiation in preventing local and pleural recurrence of thymoma.

Summary Background Data: The role of mediastinal irradiation after incomplete resection or biopsy of an invasive thymoma is well established. However, routine use of adjuvant mediastinal irradiation for patients with thymoma after complete resection remains controversial.

[Trial of a small image network system in a radiology department of an university hospital].

This paper describes the construction of an image network system in Shinshu University Hospital, and some of its current issues and advantages. Our discussion is based on our experience with a PACS system. SAIPACS, which was installed in 1990 for use in clinical conferencing and pre- and post-graduate education, and with a new CT and MRI network, which was subsequently introduced in 1993.

[Effective combination therapy using radiation and a daily low dose of cis-platinum for advanced oropharyngeal carcinoma in an elderly patient--report of a case].

An 83-year-old male with advanced oropharyngeal carcinoma was treated with combined radiotherapy and a daily low dose of cis-platinum with excellent results. In the early part of the treatment, radiotherapy was delivered in fractions of 1.8 Gy/day (5 days/week) to a cumulative dose of 20 Gy, concomitantly with UFT (400 mg/day po), but the response was not adequate.
