RESUMO

AIM: A retrospective analysis was performed in our two Institutions in order to evaluate the feasibility and reliability of a hypofractionated-radiotherapy regimen in the treatment of frail elderly patients with facial basal cell carcinomas (BCCs). PATIENTS AND METHODS: The records of elderly patients (age >75 years) with histologically-confirmed BCC, T1-2, treated to a total radiation dose of 25-30 Gy over 5-6 weeks, were retrospectively analyzed. RESULTS: From February 2007-December 2010, 134 ambulatory patients with 159 BCCs were treated. Their median age was 82.5 years (range=75-103). Grade 1-2 skin acute toxicities were observed in 30.6% of patients (41/134). Complete responses were observed in 157 tumors in 132 patients. At the last follow-up, June 2014, no late toxicities had been noted; three patients had local recurrent disease. CONCLUSION: Our results seem to demonstrate both the feasibility and efficacy of curative hypofractionated radiation therapy in elderly patients with BCCs unfit for daily irradiation.

RESUMO

PURPOSE: Administration of gemcitabine together with cisplatin at cytotoxic doses in a chemoradiotherapy regimen is hampered by a high degree of local toxicity. Using the pharmacologic properties of the drug we designed a modified schedule aimed at reducing toxicity while preserving activity. METHODS AND MATERIALS: Patients with squamous cell carcinomas of the oral cavity, pharynx and larynx, bulky T4, and/or N2 to N3 were eligible. Gemcitabine was administered at a dose of 800 mg/m2 on Days 1 and 12 and cisplatin at a dose of 20 mg/m2 on Days 2 to 5, every 21 days for 3 courses. Radiotherapy, delivered with standard fractionation, was given on Days 8 to 12 and 15 to 19 and was repeated 3 times up to a total dose of > or = 60 Gy. RESULTS: A total of 28 patients were selected. Grade 3 to 4 stomatitis was recorded in 25 patients (89%). Thirteen patients (46%) experienced Grade 3 to 4 neutropenia. Febrile neutropenia occurred in 8 patients (29%) and in 2 was complicated by infection and death. The overall complete response rate was 79%. At a median follow up of 71 months, 11 patients had a locoregional relapse (3-year locoregional control, 64%); 6 patients had distant metastases, among whom only 2 were without locoregional recurrence. The 3-year progression-free survival is 39% and 3-year overall survival has been 43%. CONCLUSION: The schedule modification did not attenuate local toxicity. Moreover, infections and especially pneumonia, were a major problem. The high activity of gemcitabine when combined with radiotherapy would most likely be better exploited in the context of modified radiation schemes.
