[Successful treatment results of S-1 administration in 2 patients, one with a remnant tumor of the larynx and metastatic tumors to the lung, and another with a metastatic tumor in the neck from the hypopharynx].

We report two successful remnant and recurrent cases of head and neck cancer treated with S-1. Case 1, a 52-year-old man, was diagnosed as supraglottic laryngeal carcinoma (T3N2cM0, squamous cell carcinoma: SCC) on January 25, 2000, and concurrent chemoradiotherapy (CCRT) was applied. After the treatment, a remnant tumor in the larynx was found by biopsy.

Efficacy of concurrent chemoradiotherapy for T1 and T2 laryngeal squamous cell carcinoma regarding organ preservation.

Background: Although the survival rate of early-stage laryngeal squamous cell carcinoma (SCC) patients treated by radiotherapy (RT) is sufficient, the larynx preservation rate is unsatisfactory. To improve the larynx preservation rate, such patients have been treated by RT with chemotherapeutic agents.

Patients And Methods: RT with or without uracil-tegafur (UFT) was performed for T1 cases, and UFT and carboplatin for T2 cases.
