Is total abdominal hysterectomy with bilateral salpingo‐oophorectomy adequate for new FIGO Stage I endometrial carcinoma?

Objective The new FIGO staging for endometrial cancer cases complies with other forms of surgical staging and correlates better with clinical outcomes because it includes prognostic factors. This study was done to investigate whether total abdominal hysterectomy with bilateral salpingo?oophorectomy (TAH + BSO) is adequate for new FIGO Stage I endometrial carcinoma. Subjects Sixty?five cases of endometrial carcinoma defined according to the new FIGO Stage Ia (n= 26), Ib (n= 24) and Ic (n= 15) were analysed. They all received TAH + BSO only and were followed up for at least two years. Methods The histologic type, grade, depth of myometrial invasion, lympho?vascular tumour emboli and tumour size were analysed by t?test to correlate the risk factors for treatment failure. Results There were no recurrences after TAH + BSO in Ia and Ib cases. However, recurrences occurred in five cases (33 %) of Stage Ic with deep myometrial invasion, high histologic grade, large tumour size and tumour emboli. Conclusions TAH + BSO is inadequate in some Ic cases with a high histologic grade, deep myometrial invasion and tumour emboli. Thus, thorough pre?operative and intra?operative staging, adequate operation method and prompt post?operative adjuvant therapy are indispensable for successful treatment.
