Background: Definitive radiotherapy (RT) for head and neck cancer is increasingly used to preserve organ function, whereas surgery is reserved for treatment failure. However, data are sparse regarding the feasibility of salvage surgery, particularly for unselected patients after accelerated RT.
Methods: From 1991 to 2001, 297 patients, most with stage III to IV cancer (Union Internationale Contre le Cancer) were treated with concomitant boost RT (median dose, 69.9 Gy in 41 fractions) with or without chemotherapy (in 33%, usually cisplatin with or without 5-fluorouracil). The 75 patients seen with local and/or regional failure were studied. We analyzed the factors influencing the decision to attempt surgical salvage, the oncologic outcome, and the associated complications.
Results: Seventeen (23%) of the 75 patients had a salvage operation. This included all five patients with laryngeal cancers but only 16% to 20% of patients with tumors in other locations. Most patients could not be operated on because of disease extension (40%) and poor general condition/advanced age (30%). Patients with low initial primary T and N classification were more likely to undergo surgery (p = .002 and .014, respectively). Median post-recurrence survival was significantly better for patients who had salvage operations than for those without surgical salvage treatment (44 vs 11 months, p = .0001). Thirteen patients were initially seen with postoperative complications (mostly delayed wound healing and fistula formation).
Conclusions: After definitive accelerated RT with the concomitant boost technique, only a minority of patients with local or regional recurrence underwent salvage surgery. Disease stage, tumor location, and patient's general condition at the initial diagnosis seemed to be the main factors influencing the decision to attempt surgical salvage. For patients with initially resectable disease who undergo radical nonsurgical treatment, more effective follow-up is needed to favor early detection of treatment failure, which may lead to a timely and effective salvage surgery.
