A review of the role of radiation therapy in the treatment of non-hodgkin lymphomas.

Until recently, non-Hodgkin lymphoma has been difficult to understand. This was due to a lack of appreciation for histologic types, their sub-classifications, modes of spread, and sites of recurrence.The treatment of choice for stage I-II disease is radiation therapy. The value of irradiating adjacent uninvolved node areas or the more extensive Hodgkin-type mantle or inverted "Y" fields is uncertain.Most patients already have reached stage III or IV when first seen. Stage III cases should be treated by a combination of radiation therapy and chemotherapy. There are protocol studies evaluating the role of chemotherapy alone in stage III disease. The primary treatment of stage IV disease probably should be chemotherapy followed by radiation therapy to involved areas or to residual bulky disease.

Carcinoma of the rectum and rectosigmoid colon: role of radiation therapy.

Surgery is the modality of choice in curative treatment for cancer of the colon and rectum. Since a majority of the patients present advanced disease where the surgical outlook is poor, adjuvant therapy may be warranted. Clinical and experimental data demonstrate the benefits from preoperative radiation therapy and some clinical reports indicate the beneficial effects of postoperative radiotherapy. Two national studies are underway to determine the effectiveness of preoperative radiation therapy in moderate doses. A similar study is suggested to establish the effectiveness of postoperative radiation therapy.For patients who are poor surgical risks, or for a tumor which is considered to be inoperable, and in a selected group, radiation therapy can be used as a curative procedure. Advantages include eliminating the need for a permanent colostomy. In case of failure, electrocoagulation and abdominal perineal resection are still available alternatives.A modest amount of radiation therapy can afford maximum palliation with minimum discomfort to the patient. About 80-90 percent of patients with pain and bleeding and 50 percent of patients with symptomatic liver metastasis respond favorably.
