To retrospectively analyze patient characteristics, treatment, and treatment outcome of pediatric patients with hematologic diseases treated with total body irradiation (TBI) between 1978 and 2006. ⋯ As severe late sequelae after TBI, we observed 2 secondary malignancies in 11 patients who survived in excess of 36 months. However, long-term morbidity is moderate following treatment with the fractionated TBI at the low-dose rate that was generally used here. Conditioning for bone marrow transplantation without radiation is an attractive option, but is not sufficiently effective to completely replace TBI for the most common pediatric indications.

:To evaluate toxicity after dose-escalated radiotherapy for prostate cancer using intensity-modulated treatment planning (IMRT) and image-guided treatment (IGRT) delivery. ⋯ High-dose radiotherapy for prostate cancer using IMRT and IGRT resulted in low rates of acute toxicity and preliminary results of late toxicity are promising.

Evaluation of CEM43 degrees CT90 thermal dose in superficial hyperthermia: a retrospective analysis.
Prospective use of the CEM43 degrees CT90 thermal dose parameter has been proposed for hyperthermia treatments. This study evaluates the CEM43 degrees CT90 parameter by means of a retrospective analysis of recurrent breast cancer patients receiving reirradiation plus hyperthermia. ⋯ In this retrospective study, no clear CEM43 degrees CT90 thermal dose targets or associations with clinical endpoints could be established.

To quantitatively evaluate the dose distributions of high-dose-rate (HDR) prostate implants regarding target coverage, dose homogeneity, and dose to organs at risk. ⋯ US-based treatment plans for HDR prostate implants based on the real positions of catheters provided acceptable dose distributions. In the majority of the cases, the doses to urethra and rectum were kept below the defined tolerance levels. For rectum, the dose in reference points correlated well with dose-volume parameters. For urethra dose characterization, the use of D1 volumetric parameter is recommended.

To evaluate the effectiveness of timing of application of prophylactic cranial irradiation (PCI) in patients with small cell lung cancer in limited stage of disease (LS SCLC). ⋯ PCI significantly decreases the incidence of brain metastases and delays their development in patients with LS SCLC. "Early" PCI is more effective than PCI applied after combined therapy.
