FREQUENCY OF SQUAMOUS CELL CARCINOMA IN POST BURN PATIENTS

Abstract

Burn injuries, particularly those leading to chronic scars, can predispose individuals to the development of squamous cell carcinoma (SCC). The risk of malignant transformation increases with burn severity and long-term scarring. Understanding the prevalence of SCC in post-burn patients is crucial for implementing preventive and management strategies. Objective: To assess the frequency of squamous cell carcinoma (SCC) in patients with post-burn scars and evaluate associations between demographic and burn-related factors with the development of SCC. Methods: A prospective descriptive study was conducted on 70 patients with a history of burn injuries and resulting scars. The study was carried out over a defined period at a tertiary care hospital. Patient demographic variables such as age, gender, socioeconomic background, and education level were collected. The severity of burns was categorized as partial-thickness or full-thickness, and the aetiology of burns was classified as thermal, chemical, or electrical. Burn locations were also documented. Histopathological examination of biopsy specimens from suspicious scars confirmed SCC diagnosis. Statistical analysis using chi-square tests was employed to identify associations between categorical variables and SCC occurrence. Results: Of the 70 patients included, 53 were males (75.7%) and 17 females (24.3%), with a mean age of 53.97 ± 4.91 years. Full-thickness burns were observed in 57.1% of the patients, while 42.9% had partial-thickness burns. The most common burn cause was thermal (45.7%), with the lower extremities being the most affected region (57.1%). SCC developed in 8.6% (6 out of 70) of the patients. The latency period for SCC ranged between 28 and 37 years, with an average of 31.5 years. Full-thickness burns were more commonly associated with SCC development compared to partial-thickness burns. Conclusion: The study reported a frequency of 8.6% for squamous cell carcinoma in patients with post-burn scars. Full-thickness burns were associated with a higher risk of SCC development. Long-term surveillance and proactive management of burn scars are critical in preventing malignant transformations.
