Chemodectoma of glomus jugulare.

A retrospective review of 17 patients with a diagnosis of chemodectomas of glomus jugulare is presented. The patients' age ranged from 32 to 63 years, with a female to make ratio of 4:1, with 14 females and 3 males. In the majority of the patients (15/17), the primary treatment was surgery, with 10/15 (70%) incidents of recurrence. Radiation therapy was used in 11 patients, in 7 for recurrence, in 2 as postoperative and in 2 as a primary therapy. The radiation dose ranged from 2200 to 5600 rad. The follow-up period ranged from 2 to 22 years. Sixteen patients were living with disease controlled at the last follow-up.

Carcinoma of the uterine cervix: review of experience at University of Kansas Medical Center.

A total of 211 patients with a diagnosis of carcinoma of uterine cervix, managed by radiotherapy at the University of Kansas Medical Center between 1969-1975 was reviewed. There were 90 patients in Stage I, 65 in Stage II, 43 in Stage III, and 13 with Stage IV disease. Squamous cell carcinoma was found to be the most common histologic type. Twenty-three patients had shown uterine extension of the disease; of these, eight had adenocarcinoma. The majority of the patients received external whole-pelvic telecobalt therapy followed by a variety of intracavitary radium applications. The combined dose to point A ranged from 5000-13,000 rad. There were 166 patients followed for five or more years. Overall five-year survival was 74% (124/166). Survival by stage: IA--92% (12/13); IB--88% (55/62); IIA2--74% (23/31); IIB--58% (14/24); IIIA&B--64% (18/28); and IV--25% (2/8). The overall three-year survival was 73% (155/211). Thirty-three patients (33/211 = 16%) developed local recurrence, and five of these patients were salvaged by surgery. Surgery for complications was required in nine patients. Rectovaginal and vesicovaginal fistulae occurred in three patients (1.5%). Local recurrence and complications vs. dose and system used were analyzed.

Results of radiation therapy in the treatment of epithelial carcinoma of the ovary.

Between 1967 and 1976, 82 patients who had epithelial carcinoma of the ovary and were treated with surgery and postoperative radiation therapy, respectively, were studied. Of these patients, 35% had Stage I disease, 16% Stage II, 45% Stage III, and 4% Stage IV. Serous cystadenocarcinoma was the histologic cell type in 54% of the patients, and mucinous cystadenocarcinoma was involved in 24%. Of the tumors, 35% were Grade 1, 34% Grade 2, 18% Grade 3, and 13% were unspecified. Survival at five years was 96% for Stage I patients, 60% for Stage II, and 60% for Stage III. No stage IV patient survived past two years. Stage III patients with no palpable tumor prior to radiation therapy did well, with 80% alive at more than two years, while only 10% of Stage III patients with palpable tumors prior to radiation therapy are alive. Patients with Stage III disease treated by whole-abdominal irradiation with a pelvic boost did better than those who received 3,000 rad or less to the pelvis. Radiation therapy continues to be an important treatment modality in epithelial carcinoma of the ovary, particularly in patients with minimal tumor burden.

Malignant salivary gland tumors: role of radiation therapy.

Malignant salivary gland tumors are rare. They represent less than one percent of all head and neck tumors. Approximately three fourths of all salivary gland tumors occur in the major salivary glands.Traditionally, the treatment of choice for these tumors is surgery. The majority of these tumors reoccur after curative surgical procedures. Local recurrence rate following surgery varies with the histology, grade, and extent of the disease.In spite of high local recurrence rate following curative surgical treatment of these tumors, radiotherapy has seldom been used as an adjuvant to surgery. The value of elective postoperative radiation therapy for subclinical microscopic disease was not recognized. Review of the literature supports the improved local control rate with the use of immediate postoperative radiotherapy. Radiation therapy proved to be effective as an adjuvant to surgery. A local control rate of better than 40 percent can be achieved by radiation therapy as a sole modality in inoperable and locally advanced cases. Radiation therapy provides an excellent palliation for locally advanced tumors or symptomatic metastases.

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.
