Clinical parameters in T1NOMO lower lip squamous cell carcinoma

This retrospective study was carried out to asses the clinical outcome of T1 (i.e., tumor 2 cm or less at greatest dimension) squamous cell carcinoma of the lower lip (SCCLL) and verify the impact of some clinical parameters on prognosis. Fifty-seven patients with histologically proven T1 SCCLL were analyzed. Fifty-two patients were never treated before admission, whereas five (8.8%) had a second radical resection of the primary tumor location; none had neck nodes (i.e., NO) or distant metastasis (i.e., MO). The global disease-specific survival rate at 32 months was 100%, irrespective of grading and type of surgery, and thus no differences were statistically detected. Therefore, we concluded that radical tumor resection is a viable procedure for T1 SCCLL, irrespectively of grading. In addition, a second surgery on the primary tumor location is possible and has effectiveness on survival. Finally, neck dissection is not necessary in cases of T1 SCCLL.
