ABSTRACT
BACKGROUND:
Radiotherapy (RT) with concurrent chemotherapy is the current standard of care for patients with unresectable locally advanced squamous cell carcinoma of the head and neck (SCCHN). Gemcitabine (GEM) is a potent radiosensitizer and in addition has activity as an anticancer agent in SCCHN. PATIENTS ANDMETHODS:
Twenty-six patients with locally far advanced SCCHN were enrolled in a chemoradiation feasibility study between November 1998 and September 2003. Use was made of conventionally fractionated RT and GEM 100 mg/m(2), which was given within 2 h prior to radiotherapy on a weekly basis starting on day 1 of RT. Response was assessed according to WHO criteria, toxicity according to NCI-CTC version 2.RESULTS:
The patients received a median of 7 (2-8) weekly cycles of gemcitabine and a median cumulative RT dose of 70 Gy (66-84.75). Hematologic toxicity was mild, but non-hematologic toxicity was severe grade 3-4 stomatitis occurred in 85% of patients, dermatitis in 69%, pharyngitis/esophagitis in 81% and 80% of the patients needed a feeding tube during treatment. All 22 evaluable patients responded (50% complete, 50% partial). Median follow up of the surviving patients is 46 months. Median disease-free and overall survival is 13 months and 19 months, respectively; 27% of the patients are alive without evidence of recurrence beyond 3 years.CONCLUSIONS:
Conventionally fractionated RT in combination with GEM 100 mg/m(2) weekly is feasible and highly active in the treatment of locally advanced SCCHN. In particular, long-term local control rate is promising. Acute mucosal toxicities are significant but manageable. Long-term toxicity interferes with normal food intake.
