Effect of Amifostine to prevent radiotherapy-induced acute and late toxicity in head and neck cancer patients who had normal or mild impaired salivary gland function.

BACKGROUND: Amifostine has a potential role for salivary gland protection in head and neck cancer patients who had radiotherapy. MATERIAL AND METHOD: Sixty-seven head and neck cancer patients were randomized to receive radiotherapy or radiotherapy plus Amifostine. The efficacy of the treatment was determined by a questionnaire evaluating dryness of mouth and the oral comfort, the RTOG/EORTC acute/late radiation morbidity scoring criteria, collection of the whole saliva and the 99mTc-pertecnetate scintigraphy of the salivary glands. RESULTS: Amifostine significantly reduced the mean questionnaire scores from 6.49 to 3.73, the incidence of grade > or = 2 mucositis from 75% to 36% and acute xerostomia from 82% to 39%. The salivary gland function returned to normal at a rate of 36.3% in the Amifostine group versus 9.1% in the control group. CONCLUSION: Amifostine is effective in reducing the incidence and severity of acute mucositis, acute and late xerostomia in head and neck cancer patients.

Acute effects of postmastectomy radiotherapy after immediate TRAM flap reconstruction in breast cancer patients.

OBJECTIVES: To study the acute effects of radiotherapy after mastectomy and immediate transverse rectus abdominis myocutaneous (TRAM) flap reconstruction in breast cancer patients treated at Ramathibodi Hospital. MATERIAL AND METHOD: Between January 2004 and March 2005, ten breast cancer patients (age 32-51 years) were treated with postoperative radiotherapy after mastectomy and immediate TRAM flap reconstruction. Medical records of these patients were retrospectively reviewed. Radiotherapy was delivered to the chest wall and reconstructed TRAM flap using 6-MV x-ray or Cobalt-60. The total dose was 45 to 50.4 Gy delivered in 25 to 28 fractions. Patients were evaluated weekly during the course of radiation and then at 1 and 2 months after treatment completion to determine acute effects or toxicities of radiation. RESULTS: During radiation, 3 patients developed erythema or mild hyperpigmentation of the skin, and 4 developed moderate hyperpigmentation. Three patients who were treated with Cobalt-60 and/or bolus to the chest wall developed skin desquamation (1 dry desquamation, 2 moist desquamation). No patient required a treatment break because of acute side effects. One patient who received chemotherapy after radiation developed recalled moist desquamation. CONCLUSION: Radiotherapy after mastectomy and immediate TRAM flap reconstruction is well tolerated and is not associated with increased acute complication or radiation interruption. The authors have noticed that chemotherapy given after radiation was related to severe skin reaction, so it should be used with caution.
