Radical radiation vs surgery plus post-operative radiation in advanced (resectable) supraglottic larynx and pyriform sinus cancers: a prospective randomized study.

AIM: Survival in head and neck cancers reflect loco-regional control. With an aim of organ and function preservation the present study was undertaken to compare local failure and survivals.

MATERIAL AND

METHODS

Between August 1991-December 1995, 72 patients with resectable advanced supraglottic cancers, were randomized to radical surgery followed by post-operative radiation therapy (Sx+PORT) (Arm I) or radical radiation therapy followed by salvage surgery (RRT+/-SSx) (Arm II).

RESULTS

Sixty-four of 72 patients were evaluable, 55 were T3 (86%) and 9 were T4 (14%) tumors. In Arm I (n=35) with a mean follow-up of 24 months (2-86 months), 21 patients were alive without disease. Six patients had recurrence, one each at local and tracheostomy stoma, four had nodal recurrence only, and two developed 2nd primary in soft palate/tonsil and parotid at 15 and 18 months respectively. In Arm II (n=29), with a mean follow-up of 24 months (3-81 months), 14 patients were alive without disease. Thirteen patients had recurrence, eight had local (one patient had persistent disease), two nodal only, three loco-regional and two patients developed distant metastasis (lung). One out of eight local recurrence and 2/2 nodal recurrences were salvaged with Sx. There was a significant difference in disease-free survival between the two treatment arms, DFS (5 years) of 70% in Arm I vs 50% in Arm II (p=0.04), but did not have any impact on overall survival OAS (5 years); 73% vs 77% (p=0.79). Voice/laryngeal preservation was possible in 18/29 patients (62%) treated with RRT+/- Sx, without significantly affecting the OAS. "Pathological upstaging" was another significant finding seen in 64% of clinical T3 after radical surgery.

CONCLUSION

RRT+/-SSx can be a feasible option in low volume, favourable resectable stage III and IV supraglottic lesions for better quality of life.
