Toxic cure: Hyperfractionated radiotherapy with concurrent cisplatin and fluorouracil for Stage III and IVA head-and-neck cancer in the community.

PURPOSE: To evaluate efficacy and toxicity of the Duke University chemoirradiation regimen for locally advanced head-and-neck cancer in a regional community cancer center. METHODS AND MATERIALS: Between June 1998 and June 2002, 50 patients with Stage III or IVA squamous cell carcinoma of the head and neck were treated definitively with concurrent combined modality therapy (CMT). Patients received accelerated, hyperfractionated radiotherapy (AFRT), 1.2-1.25 Gy b.i.d., to a median prescribed dose of 70 Gy. Chemotherapy consisted of cisplatin 12 mg and fluorouracil 600 mg/m(2) daily for 5 consecutive days during Weeks 1 and 6, followed by two cycles after AFRT. Patients with N2-N3 neck disease (n = 21; 42%) were considered for neck dissection depending on their response to AFRT and chemotherapy. Twenty-nine patients with Stage III and IVA disease treated between 1991 and 1997 with definitive RT alone served as historical controls. RESULTS: Forty-nine patients (98%) in the CMT group completed the prescribed AFRT and 38 (76%) completed four cycles of chemotherapy. Three of 8 patients who underwent neck dissection had a pathologically complete response. The median follow-up for all patients was 23 months. The actuarial progression-free survival rate at 2 years was 75% for the CMT group vs. 40% (p <0.01) for the RT group. The overall survival rate was 80% and 43% (p <0.01), respectively, for the CMT and RT groups. Acute Radiation Therapy Oncology Group Grade 3 toxicities for the CMT group were mucosal (n = 50; 100%), skin (n = 9; 18%), and hematologic (n = 3; 6%). Late Grade 3-4 toxicities consisted of pharyngeal stricture (n = 7; 14%), laryngeal chondritis (n = 3; 6%), osteoradionecrosis (n = 2; 4%), and peripheral neuropathy (n = 1; 2%). CONCLUSION: This aggressive regimen of AFRT with concurrent cisplatin and fluorouracil with or without neck dissection is feasible in the community setting for patients with Stage III and IVA head-and-neck cancer. Early results indicated excellent survival, albeit with universal acute mucosal, and considerable, although acceptable, late toxicity.

Radiation-induced bronchial stenosis: a new cause of platypnea-orthodeoxia.

Platypnea-orthodeoxia is encountered in a variety of cardiac, pulmonary, and hepatic disorders. We report its occurrence in a 59-year-old man who had had combined external-beam and high dose-rate iridium brachytherapy for a stage I non-small-cell carcinoma of the right upper lobe 2 years earlier. The post-radiation course was complicated by a severe radiation bronchitis; the onset of platypnea-orthodeoxia signalled the development of severe bronchial stenosis that was transiently relieved, initially by dilatation, and later by stent placement, though the patient ultimately died of a pulmonary hemorrhage. The dosage of brachytherapy given, the combined external-beam therapy, and the long survival after completion of radiation therapy were likely factors in the development of bronchial stenosis. We discuss the tomographic and bronchoscopic features of radiation-induced bronchial stenosis.
