The rather rare vulvar cancer is almost always a squamous cell carcinoma that mostly develops from an underlying VIN or HPV infection. In addition, lichen sclerosus et atrophicans, immune deficiency, nicotine abuse or anogenital intraepithelial neoplasias may play a role in the pathogenesis. Surgical therapy aims at an R0 resection in the sense of a complete vulvectomy or a radical local excision with, if necessary, plastic reconstruction. Also, the vulvar field resection with consideration of the compartment model has been discussed. Besides the classic inguinofemoral lymphadenectomy, in selected cases of vulvar cancer sentinel biopsies are performed by experienced surgeons in the larger centres. In contrast, systemic therapy plays only a subordinate role; in isolated cases down-staging by means of neoadjuvant chemotherapy may be useful. However, there is at present no indication for adjuvant chemotherapy. Neoadjuvant radiochemotherapy is also not to be recommended on account of its unfavourable ratio of efficacy to side effects. On the other hand adjuvant radiotherapy is indicated in cases of positive inguinal lymph nodes. According to the current data the indication should be made generously in such cases.
相对罕见的外阴癌几乎总是鳞状细胞癌,大多由潜在的外阴上皮内瘤变(VIN)或人乳头瘤病毒(HPV)感染发展而来。此外,硬化性苔藓萎缩型、免疫缺陷、尼古丁滥用或肛门生殖器上皮内瘤变可能在发病机制中起作用。手术治疗旨在实现R0切除,即完整的外阴切除术或必要时进行根治性局部切除并进行整形重建。此外,也讨论了考虑分区模型的外阴区域切除术。除了经典的腹股沟股淋巴结清扫术外,在较大的中心,经验丰富的外科医生在某些外阴癌病例中会进行前哨淋巴结活检。相比之下,全身治疗仅起次要作用;在个别情况下,通过新辅助化疗进行降期可能有用。然而,目前尚无辅助化疗的指征。由于新辅助放化疗疗效与副作用的比例不理想,也不建议使用。另一方面,腹股沟淋巴结阳性的病例需要进行辅助放疗。根据目前的数据,在这种情况下应放宽指征。
