OBJECTIVE: The purpose of this study was to evaluate the patterns of failure, overall survival (OS), disease-free survival (DFS) and factors influencing outcome in endometrial cancer patients who presented with metastatic lymph nodes and were treated with curative intent. METHODS: One hundred and twenty-six patients treated between January 1996 to December 2008 with surgery and adjuvant radiotherapy were identified from our service's prospective database. Radiotherapy consisted of 45 Gy in 1.8 Gy fractions to the whole pelvis. The involved nodal sites were boosted to a total dose of 50.4 to 54 Gy. RESULTS: The 5-year OS rate was 61% and the 5-year DFS rate was 59%. Grade 3 endometrioid, serous, and clear cell histologies and involvement of upper para-aortic nodes had lower OS and DFS. The number of positive nodes did not influence survival. Among the histological groups, serous histology had the worst survival. Among the 54 patients relapsed, only three (6%) failed exclusively in the pelvis and the rest of the 94% failed in extrapelvic nodal or distant sites. Patients with grade 3 endometrioid, serous and clear cell histologies did not influence pelvic failure but had significant extrapelvic failures (p<0.001). CONCLUSION: Majority of node positive endometrial cancer patients fail at extrapelvic sites. The most important factors influencing survival and extrapelvic failure are grade 3 endometrioid, clear cell and serous histologies and involvement of upper para-aortic nodes.

OBJECTIVE: The purpose of this study is to validate the Gynecologic Oncology Group (GOG) criteria for adjuvant treatment in a different cohort of patients and to evaluate the simplified risk criteria predicting the prognosis and tailoring adjuvant treatment in patients with surgically staged endometrial cancer. METHODS: We performed a retrospective analysis of 261 consecutive patients with surgically staged endometrial cancer between January 2000 and February 2013. All patients had complete staging procedures and were surgically staged according to the 2009 International Federation of Gynecology and Obstetrics staging system. Clinical and pathologic data were obtained from medical records. We designed the simplified risk criteria for adjuvant treatment according to the risk factors associated with survival. The patients were divided into low and low-intermediate, high-intermediate, and high-risk groups according to the GOG criteria and simplified criteria and their survivals were compared. Receiver-operating characteristic curve analysis was used to evaluate the prognostic significance of both criteria. RESULTS: Median follow-up time was 48 months (range, 10 to 122 months). According to the GOG criteria, we identified 197 low and low-intermediate risk patients, 20 high-intermediate risk patients, and 44 high-risk patients. There were significant differences in disease-free (p<0.001) and overall survival (p<0.001) among the three groups. Using the simplified risk criteria, we identified 189 low and low-intermediate risk patients, 28 high-intermediate risk patients, and 44 high-risk patients. There were significant differences in disease-free (p<0.001) and overall survival (p<0.001) among the three groups. The performance of the simplified criteria (area under the curve [AUC]=0.829 and 0.916 for disease recurrences and deaths, respectively) was as good as the GOG criteria (AUC=0.836 and 0.921 for disease recurrences and deaths, respectively). CONCLUSION: The simplified criteria may be easily applicable and offer useful information for planning strategy of adjuvant treatment in patients with surgically staged endometrial cancer as the GOG criteria.

To determine whether radical hysterectomy is necessary in the treatment of endometrial cancer patients with cervical involvement, we reviewed the medical records of women who underwent primary surgical treatment for endometrial carcinoma and selected patients with pathologically proven cervical invasion. Among 133 patients, 62 patients underwent extrafascial hysterectomy (EH) and 71 radical or modified radical hysterectomy (RH). The decision regarding EH or RH was made at the discretion of the attending surgeon. The sensitivity of pre-operative magnetic resonance imaging for cervical invasion was 44.7% (38/85). In RH patients, 10/71 (14.1%) patients had frankly histologic parametrial involvement (PMI). All were stage III or over. Eight of 10 patients had pelvic/paraaortic node metastasis and two showed extrauterine spread. In 74 patients with stage II cancer, RH was performed in 41 and PMI was not seen. Sixty-six (89.2%) patients had adjuvant radiation therapy and there were 3 patients who had developed recurrent disease in the RH group and none in the EH group (Mean follow-up: 51 months). Although these findings cannot conclusively refute or support the necessity of radical hysterectomy in patients with cervical extension, it is noteworthy that the risk of PMI seems to be minimal in patients with a tumor confined to the uterus without evidence of extrauterine spread.

OBJECTIVETo investigate the clinical and pathological characteristics, treatment methods, and prognosis of synchronous primary cancers of the endometrium and ovary.

METHODSThe clinical data of 43 patients with synchronous primary cancers of the endometrium and ovary were retrospectively reviewed. The survival was calculated by Kaplan-Meier method and compared using the log-rank test.

RESULTSThe median age at diagnosis was 49 years (range, 28-73 years). The most common symptoms were abnormal vaginal bleeding (69.8%) and abdominal or pelvic pain (44.2%).Pelvic masses were found in 39.5% of the patients and enlarged corpus in 27.9% at physical examination, while pelvic masses were found in 67.4% of the 43 patients (29 cases) and thickening or abnormal endometrium in 23.3% (10 cases) during ultrasound examination. Of 25 patients examined by CT/MRI, pelvic masses were found in 13 cases and enlarged uterus in 11 cases. All 15 patients who underwent endometrial biopsies were proven to have endometrial carcinomas. Serum CA125 level was found to be elevated in 22 of the 34 examined cases (64.7%) with a median value of 500 U/ml (range, 39-3439 U/ml). FIGO stages of endometrial carcinomas: IA 18 cases, IB 20 cases, IC 2 cases, IIA 3 cases; Stages of ovarian carcinomas: IA 19 cases, IB 4 cases, IC 7 cases, II 4 cases, III C 9 cases. Twenty-four patients (55.8%) were in stage I both endometrial and ovarian carcinomas. Thirty-one patients underwent total hysterectomy plus bilateral salpingo-oophorectomy with omentectomy and appendectomy, meanwhile, 12 patients had pelvic lymph node dissection. Thirty-eight of the 43 patients (88.4%) had a pathologically proven endometrial adenocarcinoma. The predominant ovarian histology was endometrioid or mixed tumor with endometrioid components (30/43, 69.8%). Postoperatively, 26 patients (60.5%) received adjuvant chemotherapy alone, 12 had chemotherapy plus radiotherapy, only one patient had radiation alone and the remaining 4 cases received no adjuvant treatment. The 3- and 5-year survival rates of the group were 87.4% and 71.1%, respectively. The 3- and 5-year survival rates of patients with both endometrioid and ovarian carcinomas were higher than that of those with non-endometrioid or mixed subtypes (93.8%, 82.0% vs. 79.7%, 69.0%). The 3-year and 5-year survival rates of patients with early stage disease were better than those of the other patients (93.3%, 93.3% vs. 69.7%, 36.7%). Recurrence developed in 15 patients (34.9%). It was showed by univariate analysis that lower CA125 level, early FIGO stage, and adjuvant chemotherapy plus radiotherapy significantly and positively affect the 5-year survival rates, while only early FIGO stage and chemotherapy plus radiotherapy were revealed by multivariate analysis as independent prognostic factors.

CONCLUSIONSynchronous primary cancers of the endometrium and ovary are different from either primary endometrial carcinoma or ovarian cancer, while it can usually be detected in early stage and with a good prognosis. The impact of the CA125 level on prognosis needs to be further studied. Surgical treatment alone may be enough for early stage patients. Chemotherapy plus radiotherapy may be necessary for advanced stage patients.

OBJECTIVETo investigate the impact of surgical resection extent and other clinicopathological characteristics on the prognosis in patients with clinical stage I endometrial carcinoma.

METHODSThe data of 135 surgically treated patients with clinical stage I endometrial carcinoma were retrospectively analyzed. Fifty-seven patients (group A) underwent simple hysterectomy and salpingo-oophorectomy with or without pelvic lymphadenectomy. The other 78 patients (group B) received sub-radical or radical hysterectomy and salpingo-oophorectomy with or without pelvic lymphadenectomy. The impact of surgery extent and other clinicopathological characteristics on the prognosis in patients with clinical stage I endometrial carcinoma were retrospectively analyzed.

RESULTSThere were no significant differences between two groups in the pathological stage, pathologic type, tumor grade, depth of myometrial invasion, vascular tumor emboli, ovary invasion, lymph node metastasis, positive peritoneal cytology and adjuvant therapy (P > 0.05). However, the patients in group A had a significantly shorter operating time (105 vs. 145 min), less estimated blood loss (150 vs. 300 ml) and blood transfusion (0 approximately 600 vs. 0 approximately 1200 ml), and a shorter postoperative hospital stay (12 vs. 13 days) than that in group B (all P < 0.05). The overall rates of post-operative complications were 15.8% in group A versus 26.9% in group B (P > 0.05). The recurrence rate in the group A was 14.0% versus 6.4% in group B (P > 0.05). Furthermore, the five-year survival rate in group A was 76.9% versus 85.8% in group B (P > 0.05). Multivariate analysis demonstrated that the important risk factors for clinical stage I endometrial carcinoma were deep myometrium invasion, high pathological grade, positive peritoneal cytology and ovarian metastasis, rather than surgical resection extent.

CONCLUSIONSurgery extent is not an important factor affecting the prognosis in patients with clinical stage I endometrial carcinoma, and extended surgery does not improve their survival. Therefore, excessive resection should be avoided in such cases.
