The workshop was an opportunity for Asian doctors to discuss the latest findings of gynecologic cancer, including cervical, ovarian, and endometrial cancers, as well as the future of fertility-sparing treatments, minimally invasive/radical/debulking surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy. Clinical guidelines and position statement of Asian countries were presented by experts. Asian clinical trials for gynecologic cancers were reviewed and experts emphasized the point that original Asian study is beneficial for Asian patients. In Junior session, young gynecologic oncologists presented their latest research on gynecologic cancers. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to evaluate the impact of para-aortic lymphadenectomy up to the renal vessels on the accurate staging in ovarian cancer patients presumed preoperatively to be confined to the ovary. Methods: We retrospectively analyzed data on 124 patients with primary epithelial ovarian cancer who were preoperatively thought to have tumor confined to the ovary and underwent primary staging surgery. The distribution of lymph node meta- stasis and various risk factors for nodal involvement were investigated. Results: Surgical staging yielded: 87 (70.2%) patients had International Federation of Gynecology and Obstetrics (FIGO) stage I disease and 37 (29.8%) patients had stage II-III disease: 4 IIA, 6 IIB, 9 IIC, 1 IIIA, and 17 IIIC. Eighty-six patients had pelvic lymphadenectomy only and 69 had pelvic and para-aortic lymphadenectomy. Lymph node metastases were found in 17 (24.6%) of 69 patients; 5 (7.2%) patients had lymph node metastasis in the pelvic lymph nodes only, 8 (11.6%) in the para-aortic lymph nodes only, and 4 (5.8%) in both pelvic and para-aortic lymph nodes. Six (8.7%) patients had lymph node metastasis in the para- aortic lymph node above the level of the inferior mesenteric artery. On multivariate analysis, grade 3 tumor (p=0.01) and positive cytology (p=0.03) were independent predictors for lymph node metastasis. Conclusion: A substantial number of patients with apparently early ovarian cancer had upstaged disease. Of patients who underwent lymphadenectomy, some patients had lymph node metastasis above the level of the inferior mesenteric artery. Para-aortic lymphadenectomy up to the renal vessels may detect occult metastasis and be of help in tailoring appropriate adjuvant treatment as well as giving useful information about the prognosis.

Background. The impact of micropapillary histology on survival in patients with serous borderline ovarian tumors is not established. The purpose of this study was to evaluate the significance and influence of micropapillary pattern on clinical outcome of patients with serous borderline ovarian tumors. Methods. Eighty-five patients who underwent surgery and were diagnosed with serous borderline ovarian tumors were retrospectively studied. Among these patients, 18 patients showed micropapillary pattern on histologic examination, while the remaining 67 patients did not. The significance of the presence of micropapillary pattern and relationship with various clinicopathologic findings and progression-free survival were evaluated by statistical analysis. Results. No differences with regard to age, parity, body mass index, pretreatment CA-125 level, tumor size, bilaterality, and the duration of follow-up were observed between the two groups, but there was a significant difference in terms of FIGO stage (p<0.001), invasive implants (p=0.004), performing lymphadenectomy (p=0.009), operation time (p=0.003), estimated blood loss (p<0.001), residual disease>1 cm (p=0.001), adjuvant chemotherapy (p<0.001), and the length of hospital stay (p=0.013). Progression-free survival was found to be significantly decreased in patients with invasive implants (HR, 5.06; p=0.025) and micropapillary pattern (HR, 4.20; p=0.056) on multivariate analysis. Conclusions. Micropapillary serous borderline ovarian tumors were associated with a more aggressive clinical course compared with typical serous borderline ovarian tumor. The presence of invasive implants and micropapillary pattern were significant prognostic factors in patients with serous borderline ovarian tumors. [ABSTRACT FROM AUTHOR]

Background: The aim of the present study was to investigate the long-term survival outcomes and toxicities associated with our experienced early administration of adjuvant concurrent chemoradiotherapy (CCRT).Methods: Ninety-eight patients with pelvic lymph node metastasis, positive resection margin, and/or parametrial invasion who received adjuvant CCRT between 1995 and 2011 were analyzed retrospectively. The first cycle of platinum-based adjuvant chemotherapy was initiated within 2-3 weeks after surgery (median, 12 days) and continued every 4 weeks for a total of 4 cycles. Adjuvant radiotherapy was performed during the second and third cycles of chemotherapy.Results: After a median follow-up period of 119 months for survivors, 13 patients (13.3%) experienced recurrence and 11 patients died of cancer during the follow-up period. The 5-year recurrence-free survival and cancer specific survival rates were 87.6% and 90.6%, respectively. Ninety-four patients (95.9%) received ≥3 cycles of chemotherapy. Total radiation dose of ≥45 Gy was delivered in 91 patients (92.9%). Grade 3-4 hematologic and gastrointestinal toxicities developed in 37 (37.8%) and 14 (14.3%) patients during CCRT, respectively.Conclusion: The present study confirmed the long-term safety and encouraging survival outcomes of early administration of adjuvant CCRT, suggesting the benefits of early time to initiation of adjuvant treatments.

Objective: To evaluate oncologic outcomes of minimally invasive radical hysterectomy (RH) in early cervical cancer before and after the application of parametrial invasion (PMI) criterion on magnetic resonance imaging (MRI) and vaginal colpotomy (VC). Methods: A total of 216 International Federation of Gynecology and Obstetrics stage IB-IIA cervical cancer patients who underwent minimally invasive RH was identified between April 2006 and October 2018. Patients were classified into the pre-PMI intracorporeal or VC (IVC) (n=117) and post-PMI VC groups (n=99). In the pre-PMI IVC group, PMI criterion (intact stromal ring) on MRI was not applied and the patients received IVC. In the post-PMI VC group, surgical candidates were selected using the PMI criterion on MRI and all patients received VC only. Oncologic outcomes and prognostic factors associated with disease recurrence were analyzed. Results: The rate of positive vaginal cuff margins in the pre-PMI IVC group was higher than that in the post-PMI VC group (11.1% vs. 1.0%, p=0.003). Two-year disease-free survival was different between the 2 groups (84.5% in pre-PMI IVC vs. 98.0% in post-PMI VC groups, p=0.005). Disrupted stromal ring on MRI (hazard ratio [HR]=20.321; 95% confidence interval [CI]=4.903-84.218; p<0.001) and intracorporeal colpotomy (HR=3.059; 95% CI=1.176-7.958; p=0.022) were associated with recurrence. Conclusion: The intact cervical stromal ring on MRI might identify the low-risk group of patients in terms of PMI and lymphovascular/stromal invasion in early cervical cancer. Minimally invasive RH should be performed in optimal candidates with an intact stromal ring on MRI, using VC. [ABSTRACT FROM AUTHOR]

Objective: To compare the survival outcomes of adjuvant radiotherapy and chemotherapy in women with uterine-confined endometrial cancer with uterine papillary serous carcinoma (UPSC) or clear cell carcinoma (CCC). Methods: Medical records of 80 women who underwent surgical staging for endometrial cancer were retrospectively reviewed. Stage I UPSC and CCC were pathologically confirmed after surgery. Survival outcomes were compared between the adjuvant radiotherapy and chemotherapy groups. Results: Fifty-four (67.5%) and 26 (32.5%) women had UPSC and CCC, respectively. Adjuvant therapy was administered to 59/80 (73.8%) women (25 radiotherapy and 34 chemotherapy). High preoperative serum cancer antigen-125 level (25.1±20.2 vs. 11.5±6.5 IU/mL, p<0.001), open surgery (71.2% vs. 28.6%, p=0.001), myometrial invasion (MI) =1/2 (33.9% vs. 0, p=0.002), and lymphovascular space invasion (LVSI; 28.8% vs. 4.8%, p=0.023) were frequent in women who received adjuvant therapy compared to those who did not. However, the histologic type, MI =1/2, and LVSI did not differ between women who received adjuvant radiotherapy and those who received chemotherapy. The 5-year progression-free survival (78.9% vs. 80.1%, p>0.999) and overall survival (77.5% vs. 87.8%, p=0.373) rates were similar between the groups. Neither radiotherapy (hazard ratio [HR]=1.810; 95% confidence interval [CI]=0.297-11.027; p=0.520) nor chemotherapy (HR=1.638; 95% CI=0.288-9.321; p=0.578) after surgery was independently associated with disease recurrence. Conclusion: Our findings showed similar survival outcomes for adjuvant radiotherapy and chemotherapy in stage I UPSC and CCC of the endometrium. Further large study with analysis stratified by MI or LVSI is required. [ABSTRACT FROM AUTHOR]

Purpose Genexol-PM is a biodegradable cremophor EL-free polymeric micelle formulation of paclitaxel. Here, we compared efficacy and safety of Genexol-PM plus carboplatin versus Genexol plus carboplatin for ovarian cancer treatment. Materials and Methods In this multicenter, randomized, phase II study, patients with International Federation of Gynecology and Obstetrics IC-IV epithelial ovarian cancer were randomly assigned (1:1) to receive Genexol-PM 260 mg/m2 or Genexol 175 mg/m2 with 5 area under the curve carboplatin every 3 weeks (6 cycles). The primary endpoint was the carbohydrate antigen 125 and Response Evaluation Criteria In Solid Tumor composite overall response rate (ORR). Results Of 131 enrolled patients, 98 were included in intention-to-treat analysis. Mean dosages were 260.00±0.00 mg/m2 Genexol-PM or 174.24±3.81 mg/m2 Genexol. Median followup was 18.0 months (range, 6.1 to 33.8 months). ORR was 88.0% (95% confidence interval [CI], 80.4 to 95.6) with Genexol-PM, and 77.1% (95% CI, 67.1 to 87.1) with Genexol (noninferiority threshold, 16.3%). Median time to progression was 14.8 months (95% CI, 11.3 to 20.2) with Genexol-PM and 15.4 months (95% CI, 13.2 to 29.6) with Genexol (p=0.550). Overall, six patients died. Neutropenia was the most common toxicity (incidences of 86.0% vs. 77.1%, p=0.120). Peripheral neuropathy incidences were 84.0% versus 64.6% (p= 0.148). Peripheral neuropathy of ≥ grade 3 occurred in one patient receiving Genexol. All toxicities were manageable. Conclusion Genexol-PM plus carboplatin as first-line treatment in patients with epithelial ovarian cancer demonstrated non-inferior efficacy and well-tolerated toxicities compared with the standard paclitaxel regimen. Further studies are warranted to optimize the dose and schedule, and to investigate long-term outcomes. [ABSTRACT FROM AUTHOR]

Objective: To evaluate risk factors for massive lymphatic ascites after laparoscopic retroperitoneal lymphadenectomy in gynecologic cancer and the feasibility of treatments using intranodal lymphangiography (INLAG) with glue embolization. Methods: A retrospective analysis of 234 patients with gynecologic cancer who received laparoscopic retroperitonal lymphadenectomy between April 2006 and November 2015 was done. In June 2014, INLAG with glue embolization was initiated to manage massive lymphatic ascites. All possible clinicopathologic factors related to massive lymphatic ascites were determined in the pre-INLAG group (n=163). Clinical courses between pre-INLAG group and post-INLAG group (n=71) were compared. Results: In the pre-INLAG group (n=163), four patients (2.5%) developed massive lymphatic ascites postoperatively. Postoperative lymphatic ascites was associated with liver cirrhosis (three cirrhotic patients, p<0.001). In the post-INLAG group, one patient with massive lymphatic ascites had a congestive heart failure and first received INLAG with glue embolization. She had pelvic drain removed within 7 days after INLAG. The mean duration of pelvic drain and hospital stay decreased after the introduction of INLAG (13.2 days vs. 10.9 days, p=0.001; 15.2 days vs. 12.6 days, p=0.001). There was no evidence of recurrence after this procedure. Conclusion: Underlying medical conditions related to the reduced effective circulating volume, such as liver cirrhosis and heart failure, may be associated with massive lymphatic ascites after retroperitoneal lymphadenectomy. INLAG with glue embolization can be an alternative treatment options to treat leaking lymphatic channels in patients with massive lymphatic leakage. [ABSTRACT FROM AUTHOR]

Objective To determine whether pretreatment CYFRA 21-1 levels can be a useful prognostic indicator in cervical cancer with reference to squamous cell carcinoma-antigen (SCC-Ag). Methods We retrospectively analyzed data on 506 consecutive cervical cancer patients who were treated by radical hysterectomy or primary concurrent chemoradiation therapy. The pretreatment serum SCC-Ag and serum CYFRA 21-1 levels were measured in these patients. A multivariate analysis using Cox's proportional hazard model was performed to evaluate the prognostic significance of pretreatment variables. Results In patients who underwent radical hysterectomy, there was a significant correlation between pretreatment serum SCC-Ag/CYFRA 21-1 levels and patient age, advanced FIGO stage, large tumor size, lymph node metastasis, and deep stromal invasion. In the stepwise Cox regression analysis, large tumor size > 4 cm was an independent prognostic factor for disease-free survival (OR, 3.110; [95% CI, 1.588-6.093], P = 0.001) and overall survival (OR, 8.497; [95% CI, 1.797-40.184], P = 0.007) in patients with squamous cell carcinoma, while pretreatment CYFRA 21-1 (P = 0.010) serum levels had a significant independent effect on overall survival. Likewise, pretreatment CYFRA 21-1 (P < 0.001 and P = 0.006) serum levels were the only independent prognostic factor for disease-free survival and overall survival in patients with non-squamous cell carcinoma. Conclusion Pretreatment CYFRA 21-1 levels may be considered as a useful prognostic indicator in cervical cancer with reference to SCC-Ag. [ABSTRACT FROM AUTHOR]

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.

Objective The aim of this study was to analyze clinico-pathologic factors and the optimal cut-off value of high-risk human papillomavirus (HR-HPV) viral load for predicting high-grade residual/recurrent disease after the conization in cervical intraepithelial neoplasia (CIN 2-3), adenocarcinoma in situ (AIS), and microinvasive carcinoma of the uterine cervix (MICA). Methods We retrospectively reviewed data from 701 patients with CIN 2-3, AIS, and MICA who underwent conization between September 2003 and June 2012. Receiver-operating characteristic curve analysis was used to find out the cut-off value of HR-HPV viral load for predicting residual/recurrent disease. Clinico-pathologic variables, including resection margin and HR-HPV status, were evaluated as possible predictors of residual/recurrent disease. Results At a cut-off value of 1.16 RLU/CO for post-cone HR-HPV viral load, the sensitivity was 88.2% and the specificity was 98.3%. Multivariate analysis demonstrated that post-cone cytology (p = 0.001, OR = 83.808, 95% CI = 6.688-1050.232), endocervical margin status (p < 0.001, OR = 80.478, 95% CI = 7.421-872.732), and post-cone HR-HPV status (p < 0.001, OR = 79.660, 95% CI = 8.539-743.129) were significantly associated with residual/recurrent disease. The post-cone HR-HPV positivity was observed more in the patients who showed positive endocervical margin than in the patients with positive ectocervical margin (32.6% vs. 5.3%, p = 0.002). Conclusions Follow-up using liquid based cytology in combination with HR-HPV test at 12 months after the conization, and not the early HR-HPV test, might be acceptable. Post-cone endocervical margin status combined with post-cone HR-HPV test is critical for predicting residual/recurrent disease and clinical management. [ABSTRACT FROM AUTHOR]

Purpose A phase 2 study was completed by the Korean Gynecologic Oncologic Group to evaluate the efficacy and toxicity of concurrent chemoradiation with weekly paclitaxel in patients with high-risk endometrial cancer. Methods and Materials Pathologic requirements included endometrial endometrioid adenocarcinoma stages III and IV. Radiation therapy consisted of a total dose of 4500 to 5040 cGy in 5 fractions per week for 6 weeks. Paclitaxel 60 mg/m² was administered once weekly for 5 weeks during radiation therapy. Results Fifty-seven patients were enrolled between January 2006 and March 2008. The median follow-up time was 60.0 months (95% confidence interval [CI], 51.0-58.2). All grade 3/4 toxicities were hematologic and usually self-limited. There was no life-threatening toxicity. The cumulative incidence of intrapelvic recurrence sites was 1.9% (1/52), and the cumulative incidence of extrapelvic recurrence sites was 34.6% (18/52). The estimated 5-year disease-free and overall survival rates were 63.5% (95% CI, 50.4-76.5) and 82.7% (95% CI, 72.4-92.9), respectively. Conclusions Concurrent chemoradiation with weekly paclitaxel is well tolerated and seems to be effective for high-risk endometrioid endometrial cancers. This approach appears reasonable to be tested for efficacy in a prospective, randomized controlled study. [ABSTRACT FROM AUTHOR]

Objective: The purpose of the present study was to evaluate treatment outcomes and prognostic factors in cervical cancer patients with isolated para-aortic lymph node (PALN) metastases. We especially tried to evaluate PALN factors such as size, site and number. Methods: From August 1994 to December 2009, 40 cervical cancer patients with isolated PALN node metastases at initial diagnosis were selected for analysis. Patients underwent both extended field external beam and intracavitary brachytherapy. Fourteen patients received 5-fluorouracil and cisplatin (FP) and 16 patients received weekly concurrent cisplatin. Information of PALN, such as size, site, and number, was founded before PALN radiotherapy. Results: The median follow-up time after primary treatment was 28.5 months (range, 2 to 213 months). The 3-year overall and progression-free survival rate after primary treatment was 44.3% and 31.3%, respectively. In multivariate analysis including tumor stage, performance status, and chemotherapy, FP regimen concurrent chemoradiotherapy was more effective than radiotherapy alone (p=0.030). The 3-year progression-free survival rate was 41.9% and 11.1% in patients with PALN numbers of ⩽1 and ⩾2, respectively (p=0.008). The 3-year progression-free survival rate was 42.1% and 19.2% in patients with PALN size of <1.5 cm and ⩾1.5 cm, respectively (p=0.031). Conclusion: The radiologic features of PALN, such as number or size, can be used to determine prognosis in PALN metastatic cervical cancer patients. Furthermore, FP regimen concurrent chemoradiotherapy was associated with better patient survival than radiotherapy alone. However, more studies are required to confirm possible different treatment outcomes between FP and weekly cisplatin regimens. [ABSTRACT FROM AUTHOR]

The consensus guideline development committee of Korean Society of Gynecologic Oncology was reconvened in March 2012. The committee consisted of 36 experts representing 12 university hospitals and professional organizations. The objective of this committee was to develop standardized guidelines for cervical cancer screening tests for Korean women and to distribute these guidelines to every clinician, eventually improving the quality of medical care. Since the establishment of the consensus guideline development committee, evidence-based guidelines have either been developed de novo considering specific Korean situations or by adaptation of preexisting consensus guidelines from other countries. Recommendations for cervical cancer screening tests, management of atypical squamous and glandular cells, and management of low-grade and high-grade squamous intraepithelial lesions were developed. Additionally, recommendations for human papillomavirus DNA testing and recommendations for adolescent and pregnant women with abnormal cervical screening test results were also included.

Objective: Concurrent chemoradiation therapy (CCRT) is the standard treatment for locally advanced cervical cancer. Although the optimal chemotherapeutic regimen is not yet defined, previous randomized trials have demonstrated that 5-fluorouracil (5- FU) plus cisplatin every 3 weeks and weekly cisplatin are the most popular regimens. The purpose of this study was to compare the outcomes of weekly CCRT with cisplatin and monthly CCRT with 5-FU plus cisplatin for locally advanced cervical cancer. Methods: We retrospectively reviewed data from 255 patients with FIGO stage IIB-IVA cervical cancer. Patients were classified into two CCRT groups according to the concurrent chemotherapy: weekly CCRT group, consisted of CCRT with weekly cisplatin for six cycles; and monthly CCRT group, consisted of CCRT with cisplatin and 5-FU every 4 weeks for two cycles followed by additional consolidation chemotherapy for two cycles with the same regimen. Results: Of 255 patients, 152 (59.6%) patients received weekly CCRT and 103 (40.4%) received monthly CCRT. The mean followup period was 39 months (range, 1 to 186 months). Planned CCRT was given to 130 (85.5%) patients in weekly CCRT group and 84 (81.6%) patients in monthly CCRT group, respectively. Severe adverse effects were more common in the monthly CCRT group than in the weekly CCRT group. There were no statistically significant differences in progression-free survival and overall survival between the two groups (p=0.715 and p=0.237). Conclusion: Both weekly CCRT and monthly CCRT seem to have similar efficacy for patients with locally advanced cervical cancer, but the weekly cisplatin is better tolerated. [ABSTRACT FROM AUTHOR]

Aim: The aim of this study was to assess various treatment options in stage IB2 cervical cancer patients. Methods: Between January 1995 and May 2007, 63 patients with stage IB2 were treated by radical hysterectomy (n = 28), primary concurrent chemoradiation (CCRT, n = 16) or radiation therapy (RT, n = 19). Disease-free survival (DFS) and overall survival (OS) were compared between these treatment modalities. Results: The 3-year DFS of the surgical approach group was 67.5% compared to 70.3% of the primary RT/CCRT group (p = 0.603). The 5-year OS of all patients was 75.9%. The 5-year OS of the surgical approach group was 81.6% compared to 76.2% of the primary RT/CCRT group (p = 0.578). Twelve (42.8%) of 28 surgically treated patients had high-risk pathologic factors. Out of 20 premenopausal patients who underwent the surgical approach, ovarian preservation was possible in 13 patients without adjuvant CCRT. Of these 13 patients, 7 patients did not experience disease recurrence and continued normal ovarian function. Conclusion: Both radical hysterectomy and primary RT/CCRT are effective treatment options in IB2 cervical cancer. In addition, the surgical approach can be considered for preserving ovarian function in premenopausal IB2 cervical cancer patients. Copyright © 2010 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Objective. Surgical staging of endometrial carcinoma is practiced to identify the true extent of disease. The impact of para-aortic lymphadenectomy (PALD) on survival is unproven. The purpose of this study was to determine if a staging procedure that includes PALD is associated with improved survival in endometrial carcinoma patients who had been surgically staged. Design. Retrospective review of patients' records. Setting. Ajou University Hospital, a tertiary care hospital in South Korea. Population. One hundred and sixty patients with endometrial carcinoma. Methods. We retrospectively analyzed a total of 160 FIGO stage I-III endometrial carcinoma patients without grossly metastatic para-aortic lymph nodes, who underwent surgery between 1994 and 2007. Exclusion criteria included presurgical radiation, stage IV disease and sarcomas. Two groups were identified: patients who underwent pelvic lymphadenectomy (PLD) and PALD (n=85) versus those who underwent PLD alone (n=75). Survival was analyzed using Kaplan-Meier method and Cox proportional hazards model. Main outcome measures. Disease-free and overall survival. Results. Overall, patients who underwent PALD demonstrated improved 5-year disease-free survival (81.0 vs 91.2%) and overall survival (85.8 vs 96.2%) compared to those who underwent PLD alone (p=0.019 and p=0.039, respectively). After multivariate analysis, patients' age (p=0.028), FIGO stage (p<0.001) and lymphadenectomy (p=0.014) were independent prognostic factors. The type of lymphadenectomy did not affect survival of low-risk patients. In intermediate to high-risk patients, PALD improved disease-free survival and showed a trend toward improvement of overall survival. Conclusion. These data demonstrate that PALD has a potentially therapeutic benefit on survival in surgically staged patients with intermediate to high-risk endometrial carcinoma. [ABSTRACT FROM AUTHOR]
