Fulltext PDFAims: This review seeks to define if radiotherapy is comparable to surgery in eradicating Floor of Mouth (FOM) carcinomas.
Materials and Methods: This ethics approved study-audited information on patients with a FOM squamous cell carcinoma. Data was sourced from the electronic medical record (EMR) system (MOSAIQ) for each patient, hospital notes, and referral correspondence. Analysis was performed using Pearson Chi-square or Fisher’s Exact Test. The Kaplan-Meier method described time-to-event data, with the log rank test used to assess differences between curves. Endpoints were local/ultimate local control, overall/cancer-specific survival, and time-to-development of second malignancy.
Results: Eligible were 184 patients. The majority were males with a smoking history. Surgery was used in 150 (82%) patients, with 32 treated with radiotherapy alone. There was no difference in patient and disease factors between the two populations. Five-year ultimate local control for patients treated with radiotherapy alone was 46% versus 84% for surgery alone, and 68% when combined with radiotherapy (p=0.001). There was a high likelihood of developing a second malignancy. A new primary was evident in 53 (29%) patients, with a median time to development of 4.4 years.
Conclusions: Surgery is a superior modality to radiotherapy alone to address FOM carcinoma.
