Management of pre-malignant and malignant non-melanoma skin cancers: A study from a Tertiary Care Hospital of North India

Abstract

Introduction: The incidence of non-melanoma skin cancers (NMSCs) is increasing over the last few decades. This necessitates an early diagnosis which is nowadays aided by dermoscopy. Once diagnosed early, the treatment armamentarium is diverse and includes both topical and surgical modalities. Objective: Our aim was to diagnose pre-malignant and malignant NMSCs at an early stage and treat them as per the standard protocol. Materials and Materials: Out of 136 patients of pre-malignant and malignant tumors enrolled, 100 were taken up for treatment. These were then classified into various subtypes on the basis of clinical examination and dermoscopy. The selected patients were subjected to topical treatment or surgical modalities, wide local excision or flap excision, based on the type of tumor and its size. Results: The pre-malignant group included actinic keratoses, Bowen's disease, and keratoacanthoma, whereas the malignant group included undifferentiated squamous cell carcinoma (SCC), differentiated SCC, pigmented basal cell carcinoma (BCC), nodulo-ulcerative BCC, and superficial BCC. Actinic keratoses, superficial BCCs, and five cases of keratoacanthoma were treated with topical therapies with a resolution of 90% in 86.8% cases. All the remaining cases (62 in number) were treated with conventional and flap surgery with 88% and 89.1% clearance rates, respectively, with complications in only 7 patients. Conclusion: A prompt identification of NMSCs can enable selection of the appropriate treatment modality for a specific lesion and thus reduce their associated morbidity and mortality.
