Background Rhabdomyosarcoma (RMS) occurring at nonparameningeal head and neck (NPM‐HN) sites carries a better prognosis than parameningeal RMS and some other sites. We analyzed the treatments administered and results obtained in patients with localized NPM‐HN RMS, included in the protocols coordinated by the Italian Soft Tissue Sarcoma Committee (STSC), in an effort to identify prognostic factors that could facilitate the tailoring of treatment. Methods Sixty‐six patients up to 18 years of age with previously untreated, localized NPM‐HN RMS were prospectively registered in three consecutive protocols: RMS79, RMS88, and RMS96. Primary surgery was recommended when complete tumor resection was deemed feasible without mutilations. In other cases, only a biopsy was performed, followed by chemotherapy and delayed surgery and/or radiotherapy (RT). Results NPM‐HN RMS showed favorable characteristics: 72.7% were <5 cm, 72.7% were T1, and 80.3% were N0. With a median follow‐up of 16 years (range 7–27), the 10‐year progression‐free survival and overall survival for the whole group were 65.1% (confidence interval [CI]: 52.3–75.3) and 74.2% (CI: 61.8–83.1). Progressive improvement has been seen in the successive protocols. Age and RT emerged as independent prognostic factors. The group of young children (age
