ABSTRACT: Objective: To identify the determinants of secondary limb amputation in advanced squamous cell carcinoma. Material and Methods: This was a retrospective study carried out in the Orthopedic Traumatology Department of the Bouaké University Hospital in Côte d’Ivoire from January 2013 to December 2016. It involved ten patients with locally advanced skin squamous cell carcinoma, confirmed by histology and having amputated limbs. The parameters studied were: demographic data (gender, age), socio-economic conditions (occupation, place of residence), the risk factors involved, the use of topical self-medication and the use of traditional medicine, antecedents and comorbidities factors, lifestyle, clinical aspects (seat, size), extension assessment (X-ray), anatomo-pathological examination data, duration of evolution of squamous cell carcinoma, the function of the affected limb, the treatment performed, the evolutionary modalities and the equipment. Results: Between 2013 and 2016, ten patients underwent either upper or lower limb amputations following locally advanced squamous cell carcinoma. The average age was 34.1 years (19 - 64 years). There were 7 men (70%) and 3 women (30%) and all our patients were black (sub-Saharan Africa). The majority of our patients were farmers (70%). The risk factors for squamous cell carcinoma were neglected chronic wounds. All our patients recognized during the interrogation a large use of the topicals of traditional medicine for the treatment of the initial cutaneous lesions. In terms of lifestyle, five (50%) were smokers and alcoholics. The mean time to progression of squamous cell carcinoma was 5.9 years. Lesions were localized preferentially to the pelvic limbs six (60%) cases and four (40%) to the limbs chest. The lesion was diagnosed late in all our patients. The size of the tumor in all our patients was greater than 5 cm and had a deep invasion (nerves, vessels and bone). The proximal ipsilateral ganglionic invasion was constant. The extension assessment (chest X-ray) showed two cases of pulmonary metastases. Seven patients (70%) had well-differentiated tumors. All patients underwent amputation of the affected limb, sometimes coupled with an accessible lymph node dissection. The evolution was favorable (no recurrence and infection of the amputation stump). The function of the affected limb was limited in all our patients. Seven patients (70%) survive, three of whom have been fitted to the lower limb and are regularly followed on an outpatient basis. We noted three (30%) deaths after the surgical treatment. Conclusion: Limb amputation in patients with locally advanced skin squamous cell carcinoma may be associated with cancer aggressiveness, the socio-economic conditions of patients, the quality of care, and the patient’s relationship to the disease.
