title: Delayed resection in the management of non-orbital rhabdomyosarcoma of the head and neck in childhood.
abstract: This retrospective study was undertaken to evaluate the effect of delayed resection on outcome of head and neck rms in a single institution which has experience in cranial base surgery. Since 1988, patients with primary non-orbital rms of the head and neck following treatment at the Children's Hospital of Pittsburgh, were evaluated by the Department of Otolaryngology, Eye and Ear Hospital at the University of Pittsburgh Medical Center either at the time of presentation or when response to chemotherapy and/or radiation therapy was thought to have been optimized for the possibility of definitive surgery. Medical records of patients who did or did not have delayed surgery were reviewed and compared with respect to demographics, tumor stage, response to therapy, survival, and cosmetic results. Of 16 children diagnosed with non-orbital head and neck rms from 1988-1994 and treated with chemotherapy according to IRS II-IV, 3 had group I or II disease following extensive surgery at diagnosis. Thirteen had group III or IV disease. Of these, 6 patients had delayed resection and 7 did not. Delayed resection was undertaken 3-12 months (median, 4 months) from diagnosis in 4 children who had a partial response (PR) and 2 children who had stable disease (SD) with chemotherapy and/or radiation. Delayed resection converted all children to complete responses (CR), including one child with clinical SD and one with PR who were found to have no viable tumor at surgery. The overall percentages of CRs for patients with group III or IV disease (documented any time post-diagnosis) were at least as good for patients who had undergone delayed surgery as for those who had not (100% vs. 71%, p = .465). Median survivals for patients with advanced disease were 3 1/2 years and 2 years, respectively (p = .2801). Cosmetic and functional problems attributable to surgery were not severe but included facial asymmetry (n = 4), trismus (n = 1), cranial nerve deficits (n = 1), and abnormal dentition (n = 1). In locally extensive head and neck rms, cranial base surgery should be considered after initial cytoreductive therapy, since it may contribute to achievement of CR and to survival with acceptable morbidity.
