Multi-institutional retrospective study for the evaluation of ocular function-preservation rates in maxillary sinus squamous cell carcinomas with orbital invasion
Background. This study aimed to evaluate ocular function and survival rates among treatment modalities in patients with maxillary sinus cancer with orbital invasion. Methods. Eighty-seven patients were classified according to the main treatment modality. Ocular function preservation rates and survival rates were evaluated for each therapeutic modality. Results. The 5-year overall survival rate for the en bloc resection, conservative surgery, superselective intra-arterial chemotherapy and radiotherapy (RADPLAT), intra-venous chemoradiotherapy (IV-CRT) was 70%, 35%, 49%, and 31%, respectively. Ocular function preservation rate for each group was 15%, 27%, 30%, and 17%, respectively. In the en bloc resection group, there was no significant difference in the 5-year overall survival rate between patients with orbital exenteration and those without orbital exenteration (72% vs 71%, p=0.9321). Conclusions. The en bloc resection group showed a favorable survival rate, but a low preservation rate. Preservation of orbital contents did not reduce the survival rate.
