Stereotactic radiotherapy for bone oligometastases.

About 60-90% of cancer patients are estimated to develop bone metastases, particularly in the spine. Bone scintigraphy, computed tomography (CT ) and magnetic resonance imaging (MRI ) are currently used to assess metastatic bone disease; positron emission tomography/computed tomography (PET-CT ) has become more widespread in clinical practice because of its high sensitivity and specificity with about 95% diagnostic accuracy. The most common and well-known radiotracer is 18F-fluorodeoxyglucose (FDG); several other PET-radiotracers are currently under investigation for different solid tumors, such as C or FDG-choline and prostate specific membrane antigen (PSMA)-PET/CT for prostate cancer.

Anal carcinoma of the elderly treated with radiotherapy alone or with concomitant radio-chemotherapy.

Purpose: To analyse the results achieved with radio-chemotherapy (RTCT) or radiotherapy alone (RT) in elderly patients (pts) affected with squamous cell anal cancer.

Methods And Materials: From 1990 to 2002, 62 pts aged > or =70 years were treated with RT (14) or RTCT (48). There were 9 stage I, 29 stage II, 11 stage IIIa and 13 stage IIIb.

Breast cancer in the elderly: the role of adjuvant radiation therapy.

Purpose: To evaluate available data on breast conserving surgery (BCS) with or without radiation therapy (RT), and alternative options (e.g. Tamoxifen alone) (Tam), focusing specifically on the older patients.
