ABSTRACT
PURPOSE OF THE STUDY: Basal cell carcinoma (BCC) remains as the most common cutaneous neoplasm in the Philippines consisting of more than 60% of all skin cancers. Anacardium occidentale (Linn.) cashew extract, which had been used successfully in the removal of warts and moles in previous studies, is presented as a therapeutic option in BCC. METHODS: An open-label prospective study was conducted on 36 patients (mean age of 65 years) with documented BCC lesions on middle third of the face. Cashew nut extract (DeBCC) application was offered to these patients as an alternative option to very unacceptable extirpative surgery offered by general and plastic surgeons as treatment for their lesions. Lesion size ranged from 7.5- 64 mm. (26.26 mm). Topical treatment was applied every 1-2 weeks, as needed. Follow-up examinations with photographic documentation were made every week to evaluate success of the treatment. RESULTS: After a mean of 7 treatment applications (range of 1-20) all the lesions were undetectable on clinical examinations. Mild tingling sensation, which was reported by all patients during the treatment applications, was tolerable on all occasions. With follow-up ranging from 5-60 months (38.72 months), 16 patients completed the planned 5 - year post-treatment follow-up period. There were no recurrences detected. CONCLUSIONS: Anacardium occidentale (Linn.) cashew extract (DeBCC) presents a viable and acceptable treatment option in primary BCC. The importance of this treatment option could be stressed in patients with lesions not amenable to the prescribed wide margin of resection needed in surgery.
