Multicenter StudyPhase II study of short-course radiotherapy plus concomitant and adjuvant temozolomide in elderly patients with glioblastoma.
Radiotherapy (RT) and chemotherapy may prolong survival in older patients (age ≥70 years) with glioblastoma multiforme (GBM), although the survival benefits remain poor. This Phase II multicenter study was designed to evaluate the efficacy and safety of an abbreviated course of RT plus concomitant and adjuvant temozolomide (TMZ) in older patients with GBM. ⋯ A combination of an abbreviated course of RT plus concomitant and adjuvant TMZ is well tolerated and may prolong survival in elderly patients with GBM. Future randomized studies need to evaluate the efficacy and toxicity of different schedules of RT in association with chemotherapy.

Multicenter StudyLate fecal incontinence after high-dose radiotherapy for prostate cancer: better prediction using longitudinal definitions.
To model late fecal incontinence after high-dose prostate cancer radiotherapy (RT) in patients accrued in the AIROPROS (prostate working group of the Italian Association of Radiation Oncology) 0102 trial using different endpoint definitions. ⋯ The longitudinal definitions of fecal incontinence (C_INC and M_INC ≥1) were helpful in accounting for both the persistence and the severity of the incontinence. A significant fraction of peak events was consequential to acute incontinence, and a longer duration of symptoms mainly depended on the rectal dose bath (percentage of rectal volume receiving >40 Gy), and pretreatment clinical factors.
