Body protein as a prognostic instrument for cancer patients?

Many cancer patients are affected by loss of appetite, weight loss and fatigue in the course of disease. These symptoms reduce the patients' quality of life, increase morbidity, and lessen tolerance to anti-tumor treatment. In some cases the symptoms are partly caused by various treatment modalities. The aim of this study was to investigate if radiotherapy affects the body weight and body protein of patients, and if changes in body protein have any clinical significance.

Combined therapy for undifferentiated giant and spindle cell carcinoma of the thyroid.

Undifferentiated giant and spindle cell carcinoma is an unusual and high-grade malignant type of cancer of the thyroid. The results of surgical and/or radiotherapeutic treatment have been discouraging. Only a few patients respond to therapy, usually for a short time. Recently, a few reports have been published on the effect of chemotherapy or a combined treatment of surgery, radiotherapy and chemotherapy. In the present paper the results of combining radiotherapy and chemotherapy, 5-FU and cyclophosphamide, are reported. For the future a more aggressive approach is discussed. The therapy should include surgical resection of the main bulk of the tumour, followed by radiotherapy and concomitant chemotherapy and thereafter prolonged adjuvant chemotherapy.

Arterial rupture after microwave-induced hyperthermia and radiotherapy. With reference to two patients treated for recurrence in previously operated and irradiated areas.

Two patients who developed frank arterial bleeding after combined microwave-induced hyperthermia and radiotherapy are described. One patient received re-irradiation and hyperthermia for recurrent metastatic neck nodes of a mesopharyngeal carcinoma. Full course radiotherapy had been given 6 years previously and a right-sided radical neck node dissection had been performed 4 months earlier because of recurrent neck node metastases. Six weeks after the combined therapy for a second recurrence, which achieved complete remission, a fatal rupture of the carotid artery occurred. The other patient received re-irradiation and hyperthermia for a chest wall recurrence of a breast carcinoma, treated 5.5 years previously by sector resection and tangential beam radiotherapy, and treated again 2 years earlier with extensive surgery for a local recurrence. A frank arterial bleeding from the treated region was seen after 7 months, but could be arrested with surgery. This important complication in combined hyperthermia and radiotherapy does not seem to have been recognized before. Different explanations are discussed, such as the previous local treatment as well as high temperature and atherosclerosis per se.

Quality assurance in brachytherapy: the role of the ICRU in achieving uniformity in dose and volume specification for reporting.

A quality assurance programme in brachytherapy implies a general consensus on the method of dose and volume specification for reporting. This in turn implies a consensus on certain definitions of terms and concepts. For several decades, the ICRU (International Commission on Radiation Units and Measurements) has been actively involved in an effort to reach a consensus between different brachytherapy centres worldwide, and to improve uniformity in reporting. The ICRU has prepared two reports containing recommendations for reporting brachytherapy treatments. The first, report #38 published in 1985, deals with intracavitary therapy in gynecology. The second deals with interstitial therapy, and is now in press. A summary of these two ICRU reports is presented here. Some definitions of terms and concepts are first recalled and discussed: Total Reference Air Kerma (TRAK), gross tumor volume (GTV), clinical target volume (CTV), treated volume, mean central dose, dose uniformity parameters, etc. Specific recommendations for reporting interstitial and intracavitary brachytherapy are then presented.
