Concurrent chemoradiotherapy with cisplatin and fluorouracil for locally advanced hypopharyngeal carcinoma
Abstract
The concurrent administration of cisplatin and fluorouracil (CCRT) during radiotherapy after induction chemotherapy had better results than induction chemotherapy followed by radiotherapy alone (CT+RT) for overall survival, laryngeal preservation, and locoregional control in patients with locally advanced hyopharyngeal cancer. To report treatment results comparing CCRT with CT+RT in locally advanced hypopharyngeal cancer. Sixty-six consecutive patients treated with curative intent were analyzed retrospectively. Thirty-eight patients were treated with induction chemotherapy followed by definitive RT, and 28 patients with induction chemotherapy followed by concurrent chemoradiotherapy. All patients had more than three cycles of continuous infusion of cisplatin and 5-fluorouracil every 3 weeks. The median dose of irradiation was 70 Gy in the CT+RT group and 68.4 Gy in the CCRT group, respectively. The overall 5-year survival rates were 24% for the CT+RT group and 42% for the CCRT group (p=0.031). The 3-year pharyngolaryngectomy-free survival rates were 32% for the CT+RT group and 63% for the CCRT group (p=0.032). The 3-year locoregional control rate for CCRT was significantly better than that for the CT+RT (52% vs 23%, p=0.004). A...Continue Reading
