RESUMEN
PURPOSE: To evaluate clinical results in elderly and frail patients with bladder cancer treated with curative conformal irradiation alone. METHODS: The records of ambulatory frail elderly patients, age >80 years, Charlson Comorbidity Index (CCI) >5, with invasive bladder cancer, were retrospectively analyzed. The patients were irradiated with curative intent. Acute and late toxicities were evaluated. RESULTS: A total of 27 ambulatory patients were treated. Median age was 84.5 years and a median CCI of 6.5 was recorded. Median delivered radiation dose was 64 Gy. All patients completed the planned treatment. Grade 1-2 gastrointestinal (GI) and genitourinary (GU) toxicities were observed in 55.5% of patients (15/27). At the last follow-up, no late G3+ toxicities have been observed, with G1-2 toxicities reported in 11.1% of patients (3/27). Higher values of CCI were associated with higher acute GU/GI toxicities; there was a correlation between CCI and acute GU toxicity (r = 0.43, p = 0.027). The mean survival time was 23.5 months (95% confidence interval 20.9-26.1) and no median was reached. Locoregional disease-free events and metastasis-free survival showed a 2-year actuarial rate of 90% and 87%, respectively, with an actuarial 2-year overall survival of 84.5%. CONCLUSIONS: Our results demonstrate safety and feasibility of curative radiation therapy in very elderly and frail patients with bladder cancer using 3D conformal radiation therapy.

AIMS: To quantify radiation treatments for bone metastases from breast cancer in three Sicilian provinces (Messina, Catania, Ragusa) with respect to the general population and the incidence and prevalence of breast cancer in this macro-area in a 8-year period. METHODS: All bone metastasis patients treated using radiotherapy in 8 radiation departments operating in the provinces of Messina, Catania and Ragusa were collected. Among these, metastases from breast carcinoma were analyzed according to year of irradiation. An analysis of breast cancer incidence and prevalence with respect to inhabitants in this macro-area was conducted using literature and census data. RESULTS: From January 2004 to December 2011, irradiation was delivered in 4419 bone metastasis patients. Among these, 1617 had a primary breast cancer with a median treatment per year of 206.5 (range, 164-251); 211 patients were treated in 2004 and 206 in 2011. In 2004, there were 1,048,957 female residents in the three provinces and 1,065,422 in 2011. The reported breast cancer incidence and prevalence in Sicily was respectively 100.79/100,000 and 908.54/100,000 in 2004 and 108.41/100,000 and 1091.29/100,000 in 2010. CONCLUSIONS: There has been an increase in both incidence and prevalence of breast cancer in Sicily. Nevertheless, it seems that there was no increment in skeletal-related events requiring irradiation in such patients in eastern Sicily radiation departments.
