Low-dose radiation is sufficient for the noninvolved extended-field treatment in favorable early-stage Hodgkin's disease: long-term results of a randomized trial of radiotherapy alone.

Purpose: To show that radiotherapy (RT) dose to the noninvolved extended field (EF) can be reduced without loss of efficacy in patients with early-stage Hodgkin's disease (HD).

Patients And Methods: During 1988 to 1994, pathologically staged patients with stage I or II disease who were without risk factors (large mediastinal mass, extranodal lesions, massive splenic disease, elevated erythrocyte sedimentation rate, or three or more involved areas) were recruited from various centers. All patients received 40 Gy total fractionated dose to the involved field areas but were randomly assigned to receive either 40 Gy (arm A) or 30 Gy (arm B) total fractionated dose for the clinically noninvolved EF.

[A modified facial mask device for the radiotherapy of head-neck tumors].

The reproducibility during radiotherapy of head and neck tumors has been significantly improved by special devices like individual masks. However, the temporary fixation of head and neck region to the irradiation berth induces in many patients anxiety state and reduces this way the compliance. By means of modification of the device used till now a new model in which the set up mask is only coupled to the berth, could be developed.

[Unusual site of misinterpreted bone metastases in irradiated stage IIb cervix cancer].

Bone metastases from cervical carcinoma are rare. Their frequency is reported to be 1.9-4.

[Radiological findings in malignant lymphoma of the stomach].

A retrospective review is presented of the clinical and roentgenographic findings of 40 patients with malignant lymphomas of the stomach treated at the Medical University Hannover during the period from 1971-1983. All cases of Non-Hodgkin-Lymphoma (35 primary and 5 secondary) were classified by modified Kiel classification. All patients were staged retrospectively, using modified Ann Arbor staging.

[Adjuvant therapy in breast cancer (high risk). Randomized study: radiotherapy versus combination radiotherapy and chemotherapy].

108 patients with high risk stage of a mammary carcinoma (four or more positive axillary lymph nodes) were submitted after surgery to a prospectively randomized study: a postirradiation in three series with additional administration of tamoxifen was opposed to a reduced-dose irradiation and subsequent simultaneous combination of polychemotherapy and irradiation. In patients with an age of less than 50 years, the combination of chemotherapy and radiotherapy caused a significant prolongation of the recurrence-free interval (greater than 57 months versus 12,75 months). The comparison with literature shows that an average interval of 39.
