Abstract
Introduction: Lip cancer is relatively common, despite the progress seen recently in Morocco in terms of labial-jugal cancer reconstructions. Lip cancer is often seen in advanced stages and poses management problems. Lips cancer is a frequent pathology, representing 1/5 of upper aerodigestive tract cancers and 15-30% of all encephalic extremity cancers (1). In the US, 3500-4000 new lips cancer cases are diagnosed every year, being a 2 per 100000 incidence and 500000 new cases worldwide (2). Oncologic staging for lip cancers follows the common accepted regimen from the American Joint Committee on Cancer (AJCC) and is grouped with oral cancers. Lip cancer is frequently grouped analytically with oral cavity cancers; however, the etiopathogenesis is notably different. The majority of lip cancers are preceded by a preexisting lesion, and the lower lip is the index tumor location in nearly 92% of lip cancers. In our context, this cancer is noticed at very advanced stages, thus causing a problem of medical care. Materials and Methods: We present a series of 130 cases of lip cancer collected at the National Centre of Plastic Surgery and Burns Unit at the University Hospital of Casablanca over a period of 5 years, from January 2010 to December 2014. The objective is to analyse epidemiological data, treatment and results. Results: The average age of patients was 68 years, with a sex ratio of 3. Squamous cell carcinoma were predominant. The tumoral lesions sat preferentially at the lower lip in 57.8% of the cases. 43.8% of patients were classified TI-T2, and 52.4% were classified as T3-T4. Tumor resection was complete in 125 cases and repair was immediate in all cases except one. Neck dissection was required in 33% of cases. Adjuvant therapy primarily consisted of external beam radiation on lymph nodes. The most used means of reconstruction in our series after direct sutures is Karapandzic flap in 46% of the cases. The rate of local recurrence is estimated 6.4%, and the 3-year survival is 95%. The aesthetic and functional results are considered satisfactory in 92% of the cases subject to operation.

Lip cancer must be diagnosed at an early stage; precancerous stages are keys to detect and treat the two main concerns during intervention, namely the carcinological aspect and functional and aesthetic aspect
