Endometrial cancer is increasingly common in affluent Western countries, largely owing to the growing obesity of those populations. There are two recognized types of endometrial cancer: Type I is more common and is associated with obese postmenopausal women and comprises approximately 80% of all endometrial cancers; Type II describes a woman who is often younger and thinner with a more aggressive histologic type that is nonestrogen dependent, of either serous or clear cell histology, and consists of a more aggressive clinical course and results in poorer prognosis. As the majority of patients with endometrial cancer present with symptoms and have early disease, screening is unlikely to be cost effective or reduce the mortality rate. However, surveillance of high-risk populations is a different proposition. Patients who may benefit from routine surveillance include those with a family history of endometrial cancer, a history of hormone replacement therapy with less than 12-14 days of progestogens, long-term use of tamoxifen, hereditary nonpolyposis colorectal cancer family syndrome, Cowden's syndrome, Peutz-Jeghers syndrome, a history of breast cancer and obesity. Most patients with endometrial cancer are offered surgery as first-line therapy. The standard surgical procedure should be an extrafascial total hysterectomy with bilateral salpingo-oophorectomy. Adnexal removal is also recommended, even if the adnexa appear normal, as they may contain micrometastases. The safety of a laparoscopic approach in the surgical management of uterine cancer has not yet been demonstrated in prospective randomized trials, therefore, the field awaits the Gynaecologic Oncology Group's prospective Lap-2 study. While post-treatment follow-up guidelines vary between institutions and countries, in general, patients at high risk of recurrence are followed closely every 3-4 months for the first year or two, then every 6 months to complete 5 years of follow-up.
子宫内膜癌在富裕的西方国家越来越常见,这主要归因于这些人群中肥胖率的不断上升。子宫内膜癌有两种公认的类型:I型更为常见,与绝经后肥胖女性相关,约占所有子宫内膜癌的80%;II型描述的是年龄通常较小且体型较瘦的女性,其组织学类型更具侵袭性,不依赖雌激素,为浆液性或透明细胞组织学类型,临床病程更具侵袭性,预后较差。由于大多数子宫内膜癌患者出现症状且疾病处于早期,筛查不太可能具有成本效益或降低死亡率。然而,对高危人群进行监测则是另一回事。可能从常规监测中受益的患者包括有子宫内膜癌家族史、接受激素替代疗法且孕激素使用少于12 - 14天、长期使用他莫昔芬、遗传性非息肉病性结直肠癌家族综合征、考登综合征、佩-吉综合征、乳腺癌病史和肥胖的患者。大多数子宫内膜癌患者接受手术作为一线治疗。标准手术程序应为筋膜外全子宫切除术加双侧输卵管卵巢切除术。即使附件外观正常,也建议切除附件,因为它们可能含有微转移灶。腹腔镜手术在子宫癌手术治疗中的安全性尚未在前瞻性随机试验中得到证实,因此,该领域正在等待妇科肿瘤学组的前瞻性Lap - 2研究结果。虽然不同机构和国家的治疗后随访指南有所不同,但一般来说,复发高危患者在最初的一两年内每3 - 4个月密切随访一次,然后每6个月随访一次,直至完成5年随访。
