Clinical Characteristics of Recurrent Endometrial Carcinoma: Report of 22 Cases / 中国微创外科杂志

ABSTRACT

Objective To summarize the clinical characteristics of recurrent endometrial carcinoma.Methods A total of 22 cases of recurrent endometrial carcinoma from January 2006 to December 2015 were enrolled.Primary diagnosis of endometrial carcinoma were made in our hospital,with complete clinical data and standard NCCN staging operation.The recurrence of endometrial cancer was confirmed by pathological diagnosis after second surgery or biopsy.Clinical data were retrospectively analyzed.Results The median age of primary diagnosis was 52 years old (rang,44-63 years old).And the most common clinical symptom was postmenopausal vaginal bleeding (54.5％,12/22).There were 18 cases (81.8％) of endometrial adenocarcinoma,3 cases (13.6％) of serous adenocarcinoma,and 1 case (4.5％) of clear cell carcinoma.As to the muscular layer infiltration,there were 14 cases (63.6％) ＜ 1/2,7 cases (31.8％) ＞ 1/2 and 1 case (4.5％) involving the whole layer.There were 4 cases (18.2％) of positive pelvic lymph node and no para-aortic lymph nodes metastasis.As to the postoperative clinical pathologic stage,there were 12 cases (54.5％) of FIGO Ⅰ A,5 cases (22.7％) of FIGO Ⅰ B,1 case (4.5％) of FIGO Ⅱ,and4 cases (18.2％) of FIGO ⅢC1.The median recurrent time was 4 years (rang,1.5-7 years),without obvious self-conscious symptoms,including serum CA125 elevated in 12 cases (54.5％) and positive ultrasound,CT or X-ray examination findings in 10 cases (45.5％).As to the recurrence location,14 cases (63.6％) were in the pelvic cavity,6 cases (27.3％) of retroperitoneal lymph nodes,1 case (4.5％) of anterior abdominal wall accompaning lung metastasis,and 1 case (4.5％) of lung metastasis.Three patients accept Lynch syndrome screening,of which 2 cases were positive.Conclusions Muscular layer infiltration is common in recurrence of endometrial cancer,with no obvious clinical symptoms.Pelvic cavity is the most common location of recurrence.
