几乎90％患基底细胞癌的病人,经初次治疗后即可治愈,因此长期以来认为它是无害的新生物。但每年约有10,000～15,000病人因肿瘤复发而就诊。为了获得根治,常经多次手术,终将引起严重后患甚至死亡。为探索复发因素,作者们对1976年4月至1979年11月间的811例皮肤癌病人所出现的1271个肿瘤进行分析。经以往治疗后,有496个肿瘤表现为基底细胞癌复发,经过划分组织亚型等研究,其中264例(53.2％)为实体基底细胞癌或加上另一种组织亚型,136例(27.4％)为纯硬斑病亚型,或伴有其他组织亚型,剩下的复发基底细胞癌,按其最重要的组织分为变形性、腺样或表浅性三个亚型。
Almost 90% of patients suffering from basal cell carcinoma can be cured after the initial treatment, so it has long been considered a harmless new creature. However, about 10,000 to 15,000 patients visit the hospital every year because of tumor recurrence. In order to get radical cures, often after many operations, will eventually lead to serious after-effects and even death. To explore recurrence factors, the authors analyzed 1271 tumors in 811 patients with skin cancer between April 1976 and November 1979. After previous treatment, 496 tumors showed recurrence of basal cell carcinoma. After subdivision of tissue subtypes, 264 cases (53.2%) were solid basal cell carcinomas or another tissue subtype, 136 cases (27.4). %) is a subtype of pure leaf spot, or associated with other tissue subtypes, and the remaining recurrent basal cell carcinoma is divided into deformed, adenoid or superficial three subtypes according to its most important tissue.
