Diagnosis of endometrial cancer by hysteroscopy does not increase the risk for microscopic extrauterine spread in early-stage disease

The purpose of this study was to determine whether women with endometrial cancer have a higher incidence of microscopic extrauterine spread in early-stage disease when diagnosed by hysteroscopy compared with being diagnosed by dilatation and curettage (D&C) or endometrial biopsy (Pipelle). We retrospectively reviewed the medical records of 110 patients who had undergone surgical staging for endometrial cancer from January 1997 to December 2003. They all had a preoperative histological diagnosis of endometrial carcinoma without evidence of extrauterine disease. Diagnosis was made by hysteroscopy in 64 patients (58.2%), by D&C in 17 (15.5%), and by endometrial biopsy using a Pipelle device in 29 (26.3%). The groups were compared for known prognostic factors for microscopic extrauterine spread, including age, grade, stage, and vascular space involvement, and did not differ in these parameters. Microscopic intraperitoneal disease and positive peritoneal cytology were considered the primary endpoints of this analysis. Peritoneal cytology was positive in three of 110 (2.7%) patients. The presence of positive peritoneal cytology was not associated with hysteroscopy as the diagnostic procedure. We conclude that diagnosis of endometrial cancer by hysteroscopy does not increase the risk of microscopic intraperitoneal spread compared with diagnosis by D&C or endometrial biopsy (Pipelle).     

Comparison of pretreatment assessment of intrauterine tumor spread in endometrial carcinoma using ultrasonography,hysteroscopy, and fractional curettage

Due to their age, patients with endometrial carcinoma are often in an impaired general condition and have other concomitant diseases. To prevent overtreatment or undertreatment, invasive and noninvasive diagnostic procedures such as ultrasonography, hysteroscopy, and fractional curettage were compared with regard to their capacity to assess tumor extent (in) to the cervix. In 75 patients with endometrial carcinoma, the results of transvaginal ultrasonography, diagnostic hysteroscopy, and fractional curettage in assessing tumor spread to the cervix were compared with the final pathology report on the hysterectomy specimen. Cervical involvement was demonstrated in the hysterectomy specimen in 25.3% of the patients (19 of 75). Ultrasound identified evidence of cervical involvement with a sensitivity of 15.8% (3 of 19) and a specificity of 98.1% (53 of 54); hysteroscopy had a sensitivity of 42.9% (6 of 14) and a specificity of 89.5% (34 of 38); and fractional curettage had a sensitivity of 57.9% (11 of 19) and a specificity of 66.1% (37 of 56). None of the procedures on its own is suitable for pretreatment assessment of cervical involvement. However, negative endocervical curettage and hysteroscopical exclusion of cervical infiltration may often identify patients correctly without cervical involvement, thereby avoiding overtreatment.     

Reliability of diagnostic fluid hysteroscopy in the assessment of cervical invasion by endometrial carcinoma: a comparative study with transvaginal sonography and MRI

ObjectiveThis study aimed at comparing the reliability of diagnostic fluid hysteroscopy, transvaginal sonography (TVS), and magnetic resonance imaging (MRI) to assess pre-operatively the presence of cervical involvement by endometrial carcinoma.MethodsCervical involvement was assessed by diagnostic fluid mini-hysteroscopy, TVS and MRI before surgery in 100 patients with histological diagnosis of endometrial carcinoma. Results were compared with pathological examination on surgical specimen. The sensitivity, the specificity, the positive and negative predictive values, the accuracy, the positive and negative likelihood ratios (LR) of the three techniques for recognizing the cervical involvement by the carcinoma were calculated.ResultsAt histology cervical involvement was found in 15 cases. Compared to TVS and MRI, hysteroscopy showed the highest sensitivity (0.53, 0.67 and 0.93, respectively). The specificity of MRI was significantly higher than both hysteroscopy and TVS (0.95, 0.88 and 0.82, respectively). The diagnostic accuracy of hysteroscopy (0.89) and MRI (0.91) was similar and significantly higher than TVS (0.78). The LR for a positive result of MRI was 14.16, that was 2.08 and 4.68 times higher than that of hysteroscopy and TVS, respectively.ConclusionsIn conclusion, this study demonstrates that in women with endometrial carcinoma the exclusion of cervical canal involvement at hysteroscopy is more reliable than at MRI and TVS while MRI is the most reliable technique for predicting cervical involvement. In the pre-surgical work-up of patients affected by endometrial carcinoma hysteroscopy and MRI are both useful for staging and planning the correct surgical strategy.     

Ⅱ期子宫内膜癌临床处理进展

Ⅱ期子宫内膜癌的发生率约占子宫内膜癌的12%,诊断Ⅱ期子宫内膜癌可将分段诊刮、宫腔镜检查及影像学相结合以提高分期诊断的准确性。目前对于Ⅱ期子宫内膜癌术式的选择存在争议,不同研究得出的结论不同,扩大切除范围降低复发率的同时也增加了术中和术后并发症,对此,需要仔细权衡,并需要更多的前瞻性研究进一步加以评估。术后放疗能够减少局部复发率,但对总生存率没有影响,其中阴道近距离放疗可能优于全盆腔放疗。对于合并高危因素者选择辅助化疗的生存率高于放射治疗。Ⅱ期子宫内膜癌的3年生存率为79%~85%。对Ⅱ期子宫内膜癌[2009年国际妇产科联盟(FIGO)分期]的临床特征、诊断方法、治疗及预后进行综述。     

Prognostic significance of the extent of cervical involvement by endometrial cancer

The prognostic significance of the extent of cervical involvement by endometrial cancer is impossible to determine from the literature because previous reports have included fractional dilatation and curettage for staging, preoperative radiotherapy, and surgical stage III and IV disease. Therefore, we reviewed and restaged according to the new FIGO system all patients with endometrial cancer from January 1981 to December 1989. Of 180 patients undergoing hysterectomy for endometrial cancer, 20 had surgical stage II disease. No patient received preoperative radiotherapy. None of 12 patients (0%) with stage IIA disease developed recurrence, while 5 of 8 (63%) with stage IIB disease recurred (P less than 0.01). All 5 recurrences were in extrapelvic sites. Endocervical stroma invasion appears to import a statistically significant worse prognosis than endometrial glandular involvement.     

Prognostic significance of hysteroscopic imaging in endometrioid endometrial adenocarcinoma

OBJECTIVE: The aim of this study was to relate hysteroscopic features of endometrioid endometrial adenocarcinoma to stage, grade and overall survival. METHODS: Sixty women with endometrioid adenocarcinoma underwent laparotomy and staging according to current FIGO classification. Before surgery hysteroscopy was performed in all patients to establish the morphology of neoplasia, the extent of endometrial lining involvement, and endocervical spreading. These hysteroscopic parameters were related to overall survival, surgical stage, and grade of disease. RESULTS: First-stage carcinomas were found in 50 patients, second-stage in 4, third-stage in 3, and fourth-stage in 3 patients. Well-differentiated tumors were detected in 32, moderately differentiated in 21, and poorly differentiated in 7 patients. The cumulative 48-month probability of survival was 86.6%. The morphology of adenocarcinomas was unrelated to both their stage and their grade; no relationship to survival was found. The extent of carcinomatous spread within the endometrial cavity was significantly related to stage, grade, and survival. Endometrial lining involvement of less than 50% was associated with 100% survival, 97.1% of first-stage diseases, and 96.6% of low-grade carcinomas. These percentages dropped to 73.1, 65.3 (Fisher's exact test, P = 0.001), and 76.9% (Fisher's exact test, P = 0.035), respectively, when tumoral growth involved more than half of the endometrium. Hysteroscopy detected all carcinomas metastasizing to the cervix; in 8 patients we overdiagnosed endocervical spreading, although histology was negative. From these figures, hysteroscopy showed a sensitivity and specificity in predicting cervical spread of 100 and 87.3%, respectively. CONCLUSIONS: The extent of endometrial lining involvement in patients with endometrioid carcinoma provides preoperative information on the risk of extrauterine spread. We confirm the high accuracy of hysteroscopy in excluding cervical spread.     

Sonographic, hysteroscopic, histological correlation in the early diagnosis of endometrial carcinoma.

The authors evaluate the diagnostic role of hysteroscopy and sonography in the early detection of endometrial cancer. In their experience diagnostic accuracy of transabdominal ultrasound was 87.5%; the introduction of transvaginal sonography increased it up to 95.8%, whereas hysteroscopy had diagnostic accuracy of 100%. The hysteroscopy allowed us to establish cervical canal involvement in 100% of cases. Since sonography is well accepted by patients, the authors propose to perform it in high risk patients once a year as a first level exam to show abnormal endometrial echoes. Therefore patients can be selected to undergo hysteroscopy and, if necessary, biopsy.     

A comparative study of pre-operative procedures to assess cervical invasion by endometrial carcinoma

Objective To compare the accuracy of different diagnostic procedures currently used to assess cervical involvement in endometrial carcinoma.
Design Retrospective observational study.
Setting Department of Obstetrics and Gynecology, Shinshu University Hospital, Matsumoto, Japan.
Participants Sixty-four patients with endometrial carcinoma were evaluated pre-operatively for cervical involvement by six different diagnostic procedures: cervical cytology, endocervical curettage, transvaginal ultrasonography, hysteroscopy, magnetic resonance imaging, and serum levels of CA125. The number of positive and negative diagnoses of cervical invasion by each of these procedures were correlated with the actual invasion determined by histological examination.
Results Cervical invasion was confirmed in 12 (18.8%). Endocervical curettage showed high sensitivity (91%), the highest negative predictive value (96%), and the lowest negative likelihood ratio (0.14). Hysteroscopy showed high positive likelihood ratio (8.2) and low negative likelihood ratio (0.20). Magnetic resonance imaging showed the highest positive predictive value (75%) and the highest positive likelihood ratio (12.5). Magnetic resonance imaging was excellent for predicting stromal invasion, whereas hysteroscopy was superior for assessing mucosal involvement to magnetic resonance imaging.
Conclusion Endocervical curettage is a good test for excluding cervical involvement by endometrial carcinoma. Hysteroscopy is a good test in making both positive and negative diagnoses for cervical involvement. Magnetic resonance imaging is an excellent test for detecting cervical involvement, especially when the stroma is invaded.     

Two-year follow-up of patients with endometrial carcinoma after preoperative fluid hysteroscopy

Gücer F, Tamussino K, Reich O, Moser F, Arikan G, Winter R. Two-year follow-up of patients with endometrial carcinoma after pre-operative fluid hysteroscopy. Int J Gynecol Cancer 1998; 8 :476–480.
The aim of the present study was to analyze whether pretherapeutic hysteroscopy increases the recurrence rate in patients with endometrial cancer confined to the uterus. Between January 1993 and December 1995 a total of 33 patients with endometrial carcinoma underwent surgical staging following diagnostic fluid hysteroscopy and curettage at our department. Twenty-seven patients who had disease confined to the uterus without involvement of the uterine serosa formed the study group. Fifty-five patients with endometrial carcinoma confined to the uterus who had undergone surgery after diagnostic curettage without hysteroscopy during the same period were identified as controls. The median follow-up in the hysteroscopy group and the controls was 29 months (range 26–46) and 30 months (range 10–48), respectively. In the hysteroscopy group, no patient died of disease but one patient (3.7%) developed a local recurrence 37 months after primary treatment. In the control group, one patient (1.8%) had a local and para-aortic recurrence 20 months after primary treatment. Preceding diagnostic fluid hysteroscopy does not seem to increase the risk of early recurrence in patients with endometrial carcinoma histologically confined to the uterus.     

The role of hysteroscopy in early diagnosis of endometrial cancer

The aim of this retrospective study was to compare stage, disease-free survival and overall survival in patients suffering from endometrial cancer who underwent hysteroscopy and those who did not. Between January 1, 1990 and June 30, 2001, 181 patients were referred to our Gynaecologic Department for primary endometrial carcinoma; from clinical charts we reviewed the personal and pathological data of all patients. Patients were divided into two groups: those with hysteroscopy (69 patients) and those without (112 patients). Endometrial biopsy was performed at the end of hysteroscopy. We compared symptoms at diagnosis, stage and survival. Hysteroscopy demonstrates a high diagnostic accuracy for endometrial cancer. In our case series we obtained a sensitivity of 93.10%, specificity of 99.96%, positive predictive value of 98.18% and negative predictive value of 99.85%; when hysteroscopy was associated with endometrial biopsy the sensitivity was 96.55% and specificity 100%. In this study we had a significant difference in stage Ia; in the group with hysteroscopy, stage Ia cases were 23.2% while in the group without, stage Ia cases were 15.2%. Survival in stage Ia only was 100% and 91.7%, respectively, at three and five years. In conclusion hysteroscopy was found to have a very important role in the early diagnosis of endometrial cancer, especially when it is limited to the mucosal surface.

Abstract：

Objective To evaluate the clinical significance of positive peritoneal cytology in patients with endometrial cancer.Methods The records of 315 patients with endometrial cancer who were operated at Cancer Hospital, Fudan University between January 1996 and December 2008 were reviewed.Peritoneal cytology were performed and diagnosed in all patients.Factors related with peritoneal cytology were analyzed by correlation analysis.Log-rank test and Cox regression test was used for the analysis of prognosis,respectively.Results (1) Peritoneal cytology were positive in 30 (9.5%) patients.Positive peritoneal cytology was associated with pathological subtype ( P = 0.013 ), stage ( P = 0.000 ), myometrial invasion ( P =0.012), lymph-vascular space invasion ( P = 0.012 ), serosal involvement ( P = 0.004 ), cervical involvement ( P = 0.016), adnexal involvement ( P = 0.000), and omental involvement ( P = 0.000), with no association with grade ( P = 0.152 ) and lymph node metastasis ( P = 0.066 ).( 2 ) Three-year overall survival (OS) and progression-free survival(PFS) were 93.0% and 85.5% ,respectively.Positive peritoneal cytology, surgical stage, pathological subtype, myometrial invasion, grade, and lymph-vascular space invasion were significantly associated with worse prognosis by univariate analysis ( P ＜ 0.05 ), while only surgical-pathology stage and myometrial invasion were independent prognostic factors by multivariate analysis ( P ＜ 0.05 ).For 30 cases with positive peritoneal cytology, the patients with no high risk factors shown significantly prognoses better than those with any risk factors.The results shown that for patients with late stage (stage Ⅲ - Ⅳ ) endometrial cancer with positive peritoneal cytology was significantly associated with the worse OS and PFS by multivariate analysis ( P = 0.006).Conclusions Positive peritoneal cytology was associated with serosal involvement, cervical involvement, adnexal involvement, omental involvement, and late stage.Therefore, peritoneal cytology should be performed and reported separately as a part of full surgical staging procedure.     

Management of endometrial cancer with suspected cervical involvement

The 1989 International Federation of Gynecology and Obstetrics (FIGO) staging system for endometrial cancer cells for operative assessment of the extent of uterine disease, grade, and sites of metastasis before assigning a stage to the cancer. In the current study, 70 endometrial cancer patients with suspected cervical involvement based on a positive endocervical curettage or punch biopsy were treated with initial surgery followed by tailored radiation or chemotherapy. Only 37% of the patients had operative findings consistent with the preoperative suspicion of stage II disease. Postoperative therapy was determined by the extent of cervical involvement, depth of myometrial invasion, cell type, tumor grade, and the presence and location of extra-uterine disease. Based upon these parameters, 21 patients were believed to have low risk for pelvic recurrence and received no adjuvant therapy (90% 5-year survival); 38 patients received postoperative pelvic radiation because of high-risk factors for pelvic recurrence or pelvic nodal involvement (65% 5-year survival); and 11 patients received chemotherapy and/or extended radiation because of extrapelvic disease (no 5-year survivors). The approach outlined supports initial surgery for cases of endometrial cancer with suspected cervical involvement. This approach permits accurate surgical staging under the new FIGO system, avoids radiotherapy in many patients whose disease is less extensive than suspected preoperatively, and can accomplish good local control with limited morbidity.     

Role of wide/radical hysterectomy and pelvic lymph node dissection in endometrial cancer with cervical involvement

OBJECTIVE: The goal of this work was to assess retrospectively the role of wide/radical hysterectomy (RH) and pelvic lymph node dissection (LND) in endometrial cancer with cervical involvement. METHODS; From 1984 to 1993, 82 patients with endometrial cancer and cervical involvement were surgically managed at our institution. Of 57 patients with stage II (59%) or III (41%) disease receiving no preoperative therapy, 22 (39%) had simple hysterectomy (SH) and 35 (61%) had RH. Forty-four patients (77%) had pelvic LND, and 38 (67%) had adjuvant radiotherapy (RT). Median follow-up was 70 months. RESULTS: The 5-year disease-related survival (DRS) and recurrence-free survival (RFS) were 73 and 63%, respectively. Five-year DRS and RFS were 68 and 50%, respectively, in the SH group compared with 76% (P = 0.1) and 71% (P = 0.04) in the RH group. Distant recurrences occurred in 45% of patients with SH and in 23% with RH (P = 0.08). Local recurrence rates did not differ significantly. Considering only stage II tumors, we did not observe any recurrence among patients with negative nodes who had RH, irrespective of the administration of adjuvant RT. By contrast, adjuvant RT improved local control (even if not significantly) in stage II patients who had SH. Five-year DRS of stage III patients was 47%, but it was improved by adjuvant RT in the subgroup of patients who had RH. Independent variables associated with prognosis were stage III disease, deep myometrial invasion, RH, and adjuvant RT. CONCLUSION: RH and adjuvant RT appear to improve prognosis in endometrial cancer with cervical involvement. In particular, radical surgery alone is therapeutic in stage II patients with negative nodes, irrespective of the administration of RT. By contrast, RT can possibly improve local control in stage II patients who previously had SH. Overall, stage III patients have a poor prognosis that can be improved by a combination of radical surgery and adjuvant RT; however, associated therapy directed to extrapelvic sites is probably needed in patients with extrauterine disease.     

Fractional curettage, hysteroscopy and imaging techniques: transvaginal sonography (TVS), magnetic resonance imaging (MRI) and computed tomography (CT) in the diagnosis of cervical canal involvement in cases of endometrial carcinoma

The value of preoperative diagnostic procedures (FC, hysteroscopy, TVS, MRI, CT) used to evaluate cervical canal involvement in cases of endometrial carcinoma was assessed. The results of these diagnostic methods were compared to postoperative pathologic examination results. Evaluation of the cervix by CT was limited. High NPV of the rest of the methods together with their negative results allowed us to exclude cervical infiltration with a high probability. Alas, none of them was adequate to confirm the presence of cervical involvement because of their low PPV which ranged from 8.3% (hysteroscopy) to 50% (MRI). Among all these diagnostic procedures TVS was relatively efficient (77.8%), specific (78%), sensitive (75%) and inexpensive. This method is preferable in the evaluation of possible cervical infiltration.     

Role of hysteroscopy and endometrial biopsy in women with unexplained infertility

Objectives

This study was designed to evaluate the role of hysteroscopy and endometrial biopsy in women with unexplained infertility.

Patients and methods

Women with unexplained infertility were included in this prospective study, evaluated with transvaginal sonography and diagnostic hysteroscopy. Diagnostic hysteroscopy was performed between the 7th and 11th day of the cycle. The criteria for hysteroscopic findings were based on the cervical canal, uterine cavity, endometrium, visualization of the ostium tubae and lesions of the utero-tubal junction. After the hysteroscopic examination, endometrial biopsy was performed using a Pipelle^® endometrial suction curette. Patients were classified according to the hysteroscopy results into four groups: patients with no abnormality detected (14), patients with cervical abnormalities (six), patients with endometrial abnormalities (73) and patients with uterine abnormalities (seven).

Results

One hundred women with unexplained infertility were included. All patients underwent diagnostic hysteroscopy, except for seven patients: six patients had stenotic external or internal cervical ostium and one had inadequate visualization as the uterine cavity was filled with blood. Based on hysteroscopic findings, 31 patients were finally diagnosed with endometrial polyps; 14 endometritis; 15 endometrial hyperplasia; six submucous myomas; seven intrauterine synechiae (73 cases = endometrial abnormalities group); seven congenital uterine anomalies (uterine abnormalities group), six cervical stenosis (cervical abnormalities group) and 14 women without any uterine abnormalities (no abnormalities group). Analysis of samples obtained using the Pipelle^® endometrial suction curette was non-diagnostic in 16 cases; the most common endometrial pathological feature detected by this analysis was endometritis (15 %).

Conclusions

Routine hysteroscopy and endometrial biopsy should be used as a basic part of the work-up for women with unexplained infertility.     

Does diagnostic hysteroscopy in patients with stage I endometrial carcinoma cause positive peritoneal washings?

OBJECTIVES: Previous studies have shown that positive peritoneal washings may adversely affect cancer survival rates and that hysteroscopy is associated with a higher risk of positive washings in patients with endometrial carcinoma. Our aim was to assess if diagnostic hysteroscopy increases the risk of positive peritoneal washings in patients with endometrial cancer and affects the prognosis after surgery. STUDY DESIGN: Retrospective cohort study. The medical records of 50 consecutive patients with endometrial carcinoma, diagnosed with hysteroscopy and tissue sampling and treated by abdominal hysterectomy with bilateral salpingo-oophorectomy and peritoneal washings were reviewed. RESULTS: Of the 43 patients with endometrial carcinoma FIGO stage I, none had positive peritoneal washings (95%CI: 0-8.2%). The mean interval between hysteroscopy and surgery was 33.5 days. The 5-year disease-specific survival rate was 91.8%, the 5-year recurrence-free survival rate was 85.4%. CONCLUSIONS: Diagnostic hysteroscopy had no adverse effect on the incidence of positive peritoneal washings or on prognosis in stage I endometrial cancer patients.     

Surgical staging for patients presenting with grade 1 endometrial carcinoma

OBJECTIVE: To examine the impact of surgical staging of patients presenting with grade 1 endometrial cancer. METHODS: The charts of all patients who presented for surgery for endometrial cancer between March 1997 and July 2003 were analyzed for demographic data, final tumor histology, grade, stage, and complications. RESULTS: A total of 349 patients underwent surgical management for endometrial cancer. Preoperatively, 181 (52%) were identified with grade 1 disease, with a mean age of 61 years (range 27-89). Surgical staging (pelvic +/- para-aortic lymphadenectomy) was performed in 82% of cases and was omitted only in cases when disease was apparently confined to the endometrium and surgical risk was high. In staged patients, 3.2% had severe surgical complications. There were 2 perioperative mortalities (1 pulmonary emboli and 1 myocardial infarct). In comparison of pre- and postoperative histology, 19% of patients were upgraded, with 15% grade 2, 0.5% grade 3, 2.5% serous or clear cell, and 1% mixed mesodermal tumor. Lymph node metastases were found in 3.9% of patients presenting with grade 1 endometrial cancer, and 10.5% had extrauterine spread (> IIb). High-risk uterine features, including myometrial invasion more than 1/2, grade 3 lesions, high-risk histologic variants, and/or cervical involvement, were found in 26% of the patients. No patients with stage Ia-IIb endometrioid cancer received adjuvant teletherapy or chemotherapy. Four patients with low-risk uterine features were found to have extrauterine disease. Twelve percent of patients received adjuvant therapy, and 17% avoided teletherapy and/or chemotherapy based on surgical staging. CONCLUSION: Surgical staging in patients presenting with grade 1 endometrial cancer significantly impacted postoperative treatment decisions in 29% of patients. Omitting lymphadenectomy in patients presenting with grade 1 endometrial cancer may lead to inappropriate postoperative management.     

Does Radical Hysterectomy for Clinically Apparent Stage II Endometrial Cancer Affect Risk of Local Recurrence?

ObjectiveCompare recurrence-free survival (RFS) and morbidity between radical hysterectomy (RH) and simple hysterectomy (SH) for clinically diagnosed stage II endometrial cancer.MethodsA multicentre, retrospective study, from 2000 to 2015, involving patients with endometrial cancer with cervical involvement preoperatively and stromal invasion on final pathology. Wilcoxon rank-sum test, Fisher exact test, Kaplan-Meier survival functions, and Cox proportional hazards models were used for analysis.ResultsNinety of 1613 patients had clinical stage II endometrial cancer; 57 underwent RH and 33 underwent SH, with no difference in adjuvant treatment or morbidity. About half of patients (51%) had pathologic stage III–IV disease. Mean follow-up was 3.3 and 3.8 years for SH and RH, respectively. Thirty-three percent of patients with RH and SH experienced a recurrence. Most recurrences were distant: 90% with SH and 79% with RH. There was no difference in RFS between groups (2-year: SH 65% vs. RH 75%; 5-year: SH 54% vs. RH 63%; P = 0.72). Controlling for stage, adjuvant treatment, and margin status, RH was not associated with RFS (HR 0.62; 95% CI 0.28–1.35). Among 44 patients with pathologic stage II disease, 7 had a recurrence (4 SH and 3 RH); 6 of 7 had distant recurrences.ConclusionsFifty-one percent of patients with clinical stage II endometrial cancer had advanced disease on final pathology, highlighting the importance of surgical staging. RH was not associated with RFS or reduced morbidity. Most recurrences were distant. Although RH could be performed to achieve negative surgical margins, SH may be sufficient for central, small tumours given the high risk of advanced disease and distant recurrence. Research efforts should further elucidate the ideal management of these patients.     

Survival of women with surgical stage II endometrial cancer.

OBJECTIVE: The aim of this study was to report survival and determine prognostic factors and results of therapy in women with surgical stage II endometrial cancer. METHODS: Forty-eight consecutive women with surgical stage II endometrial cancer treated at the University of Vermont between March 1984 and March 1998 were reviewed. Patients' characteristics, surgical procedure, postoperative treatment and its complications, and tumor recurrence and its treatment were recorded. In addition, a formal review of their pathological material for confirmation of the diagnosis was performed. RESULTS: The median duration of follow-up was 6.2 years. Three patients (6.3%) had tumor recurrence and two (4.2%) died of their disease. The estimated 5-year overall survival and disease-free survivals were 92.1% (SE = 5.5%, 95% confidence interval: 81.3, 100%) and 89.9% (SE = 5.8%, 95% confidence interval: 78.5%, 100%), respectively. None of the patients treated by total abdominal hysterectomy followed by both whole pelvic and vaginal cuff radiation therapy (the main line of treatment for patients in whom cervical involvement was diagnosed following hysterectomy, n = 20) or by radical hysterectomy (the main line of treatment for patients in whom cervical involvement was known before hysterectomy, n = 11) had tumor recurrence. Three of 17 (17.6%) patients treated with total abdominal hysterectomy followed by either whole pelvic (n = 13) or vaginal cuff (n = 4) radiation therapy had tumor recurrence. The difference between those two groups was statistically significant (0/31 versus 3/17, P = 0.02). There was no difference in survival among women with stage IIA and IIB or women who underwent radical abdominal hysterectomy and those who underwent total abdominal hysterectomy with postoperative pelvic and vaginal cuff radiation. Morbidity secondary to therapy was mild. Age, depth of myometrial invasion, tumor histology, and grade were not significantly related to recurrence. CONCLUSIONS: Survival of women with surgical stage II endometrial cancer is excellent especially among those treated with total abdominal hysterectomy followed by both pelvic and vaginal cuff radiotherapy or by radical abdominal hysterectomy.
