ABSTRACT
Introduction:
Non-melanoma skin cancer is the most frequent neoplasm in Brazil, with an estimated 176,930 new cases during the 2020-2022 period, with basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) as the most common subtypes. Surgical treatment of the lesions is effective, with a recurrence rate varying between 3 and 23%, with compromised margins being an important prognostic factor for this recurrence, increasing the importance of complete excision of the tumor.
Method:
To prepare this work, 1127 lesions treated at the Hospital de Amor Amazônia were analyzed, seeking to quantify cases and analyze surgically compromised margins through a retrospective analytical descriptive study. For this, histopathological reports of the operated patients were reviewed, dividing them according to sex, age, lesion topography, date of excision, lesion diameter, lesion depth, presence of ulceration, compromised margins, and histological type.
Results:
Among the lesions treated, 65% were BCC and 35% SCC, both histological types presenting a low incidence of compromised margins. In cases of CPB impairment, treatment via exeresis was chosen in 100% of cases. Concerning BCC impairment, the majority opted for clinical follow-up, with reapproach in only 9% of cases.
Conclusion:
This study demonstrates that the cases treated at the Hospital de Amor Amazônia align with the epidemiological data in the main literature, except for finding a higher incidence of non-melanoma skin cancer in men. In addition, this work demonstrates good results in the clinical approach of compromised margins in BCC lesions.
