AIM: To analyze the results of stage II glottic carcinoma treated with radiotherapy or surgery.
PATIENTS AND METHOD: One hundred thirty-four patients with squamous cell carcinoma of the T2N0M0 glottic carcinoma treated at the Osaka Medical Center for Cancer and Cardiovascular Diseases from 1979 through 1991 were reviewed. The 5-year disease-free survival and laryngeal preservation rate and prognostic factors were examined. Treatment was radiation therapy with salvage surgery for failure or surgery alone.
RESULTS: The 5-year disease-specific survival rate for the radiotherapy group was 100% and for the surgery group, 93% (p = 0.055). In the surgery group 5-year disease-specific survival rate for the subgroup of cord mobility was 94% and that of impaired cord mobility, 89% (p = 0.5354). Concerning laryngeal preservation the radiotherapy group showed better preservation rate than the surgery group in the subgroup of cord mobility, i.e., 41/51 (80%) versus 6/55 (11%) (p < 0.001) although significant difference was not observed in the lesion with impaired cord mobility, 2/5 versus 4/22 (p = 0.171).
CONCLUSION: We recommend radiation therapy for stage II glottic carcinoma with normal cord mobility, although further study is needed to improve the preservation rate of the larynx with keeping the disease-specific survival for the lesion with impaired cord mobility.
