A clinical study on skin cancer in Indonesian patients

A case control study has been perfonned since January 1996 until March 1999, concerning the chmcal aspects of skin cancer at Dr. Cipto Mangunkusumo National Central General Hospital (RSUPNCM) Jakarta, as a joint research between Indonesia and Japan. So far we have stiuliect 139 skin cancer cases and found 91 (65.5 %) basal cell carcinoma (BCC). 32 (23.0 %) squamous cell carcinoma, (SCC) 11(7.9%) malignant melanoma (MM), while lentigo maligna, solar keratosis, basosquamous carcinoma and Bowen s disease in 1 patient, respectively. All the cases were obtained from the policlinic of the Department of Dermatology and the Department of Surgery, Oncology subdivision, Dr. Cipto Mangunkusumo National Central General Hospital Jakarta. From the 91 BCC cases. 53 (58.2 %) were females and 38 (41.8 %) were males. Their age range between 32-87 years old (mean - 59.4 ± 122 yrs). The sites of BCC were almost all on the face, except for two cases on the back and hand. SCC found in 3l cases consisted of 13(40.6 %) females and 19(59 4 %) males. Their age range between 24-85 years old (mean = 57.8 ± 15.5 yrs). MM occurred mil patients, consisting of 8 (72.7 %) females and 3 (27.3 %) males. The age ranged between 30-80 years (mean = 51.6 ± 16.2 yrs) They were also evaluated against localization in sun exposed and non-sun exposed part of the skin. The majority of BCC, i.e.. 88 (96.7 %) of 91 was located at sun exposed area. Among SCC cases 12 (37.5 %) occurred on sun exposed area and 20 (62.5 %) on non-sun exposed area. Among MM cases 3 (27,3 %) occurred on sun exposed area and 8 (72.7 %) on non- sun exposed area. The ratio of BCC to SCC is 91:32=2.8:1.
