To review and describe the anatomoclinical cases of the endometrial cancers arising on polyps during a hormonotherapy by tamoxifen for breast cancer.
In the surgical inventory 1990-2002 of the benign or malignant uterine lesions investigated by hysteroscopy with dilatation & curettage (D&C) and/or hysterectomy, 108 single or multiple endometrial polyps were encountered and histologically analyzed.
A malignant transformation of polyp was found in 5 instances, meaning a rate of 4.6% i.e. 5/108: 4 cases of adenocarcinoma, 1 case of sarcoma.
The existence of endometrial polyps - symptomatic or not - does not seem compatible with the prolonged use of tamoxifen treatment owing the estrogen agonist potential effects of tamoxifen and its well-known hyperplastic and carcinogenic properties for the endometrium. The increased risk of endometrial cancer developing in polyps in this iatrogenic context is estimated between 2.5% and 10% in the literature.
回顾并描述在他莫昔芬治疗乳腺癌的激素治疗期间发生于息肉的子宫内膜癌的解剖临床病例。
在1990年至2002年通过宫腔镜检查联合扩张刮宫术(D&C)和/或子宫切除术对良性或恶性子宫病变进行的手术记录中,发现了108个单发或多发子宫内膜息肉并进行了组织学分析。
发现5例息肉发生恶性转化,即发生率为4.6%(5/108):4例腺癌,1例肉瘤。
无论有无症状,子宫内膜息肉的存在似乎都与他莫昔芬的长期使用不相容,这是由于他莫昔芬具有雌激素激动剂的潜在作用及其对子宫内膜众所周知的增生和致癌特性。在这种医源性背景下,息肉中发生子宫内膜癌的风险增加,文献估计在2.5%至10%之间。
