Supportive therapy in radiation oncology.

Measures for supportive care of the radiation therapy patient are presented. These include emotional support prior to and during the course of therapy facilitated by a written interview that allows the radiation oncologist to be a supportive communicator of realistic information. A discussion is made of the support of body tissues affected by combination radiation and chemotherapy. These tissues usually include skin, oral, esophageal and intestinal mucosa, and teeth. Means of maintaining nutritional support following weight loss of patients during therapy are described.

Radiation therapy of choroidal melanoma.

During the past 8 years, 32 patients with melanoma of the choroid have been treated with cobalt-60 ophthalmic applicators. Excluding three patients lost to follow-up, 24 patients who have now been observed for at least 3 years after treatment form the subject of this study. Each application but two delivered 8,500 to 10,000 rads to the tumour apex. A second application was performed in large tumours showing a poor response to the initial plaque treatment. The factors affecting results include age of the patient, tumour size, total dose delivered, and dose rate. Three out of seventeen patients with tumour diameters greater than 12 mm died of their disease with pulmonary and/or liver metastasis. Three eyes required enucleation and no residual tumour was found in two specimens. Three patients, average age 76 years, died from causes other than melanoma. An 83 per cent relative survival, excluding the three patients lost to follow-up, compares favourably with enucleation. The low incidence of metastasis after radiotherapy suggests augmentation and/or continuation of the host's immune response. Low energy radiation using Iodine-125, with its unusual protective characteristics is ideal for treatment of choroidal melanoma.

Renal metastases simulating Kaposi sarcoma. Radionuclide scanning, an aid in diagnosis and treatment planning.

A case of renal cutaneous metastases simulated Kaposi sarcoma and the condition was misdiagnosed as Kaposi sarcoma. A new technique was employed using the isotope technetium 99m as the compound sodium pertechnetate Tc 99m for the diagnosis and evaluation of the extent of Kaposi sarcoma. The failure to demonstrate a positive isotope scan in our case was a clue to the incorrect diagnosis of Kaposi sarcoma.

A clinical and follow-up study of right and left bundle branch block.

The experience with bundle branch block at the USAF School of Aerospace Medicine was reviewed. The clinical and follow-up status was evaluated in 394 subjects with right bundle branch block (RBBB) and 125 subjects with left bundle branch block (LBBB). The majority of subjects were asymptomatic at the time of bundle branch block diagnosis. The subjects were divided into subfroups based on electrocardiographic (EEG) findings to determine if any one subfroup was at higher risk for initial or follow-up morbidity of cardiobascular disease or follow-up mortality. At initial diagnosis and clinical evaluation, 94% of RBBB and 89% of LBBB subjects had no evidence of cardiobascular disease. In the RBBB group, 3 and 2% had cornary heart disease and hypertension, respectively; in LBBB subjects, 9 and 7% had cornary heart disease and hypertension, respectively. No one ECG subfroup in either the RBBB or LBBB group had a higher incidence of cardiobascular disease. Complete follow-up information was available in 94% of the RBBB subgroup subjects and 91% of the LBBB group. In the follow-up period, new cases of coronary heart disease and hypertension occurred in 6% of the RBBB group and 5 and 8%, respectively, in the LBBB group. Fourteen (4%) RBBB and nine (8%) LBBB subjects died during the follow-up period. No differences for follow-up groups. Progressive electrical dysfunction in the form of complete heart block occurred in one subject each absence, and degree of associated cardiobascular disease. Furthermore, within the age limits of the present aeromedical implications of bundle block are discussed.
