Survival analysis of pelvic lymphadenectomy alone versus combined pelvic and para-aortic lymphadenectomy in patients exhibiting endometrioid type endometrial cancer.

ABSTRACT: The therapeutic benefit of lymphadenectomy in patients exhibiting endometrial cancer (EC) remains controversial. The aim of the present study was to determine whether the addition of para-aortic lymphadenectomy to pelvic lymphadenectomy (PLND) improves survival in patients with endometrioid type EC. A single tertiary-center, retrospective analysis was conducted in a total of 186 patients who were surgically treated with either PLND alone (n=97) or combined pelvic and para-aortic lymphadenectomy (PPaLND; n=89). Adjuvant treatments were assigned according to the Gynecologic Oncology Group (GOG) risk of recurrence analysis. The primary endpoint of the present study was progression-free survival (PFS). The median follow-up time was 38 months (95% confidence interval, 36.47-42.90) for all patients. No statistically significant differences were identified between the two groups in terms of overall survival (OS), PFS or time to progression (TTP). Kaplan-Meier estimates of three-year OS, PFS and TTP for patients with low or low-intermediate risk were as follows: PLND, 100, 98.7 and 98.7%, respectively; and PPaLND, all 100%. The estimated three-year OS, PFS and TTP for patients with high or high-intermediate risk were as follows: PLND, 92.3, 81.3 and 81.3%; and PPaLND, 90.7, 77.1 and 80.9%, respectively. No statistically significant differences were detected in the three-year OS, PFS and TTP between the lymphadenectomy groups, regardless of the GOG risk of recurrence (PLND, 98.4, 95.3 and 95.3%; and PPaLND, 94.9, 87.1 and 89.4%). Therefore, the combination treatment, PPaLND did not provide any survival advantage over pelvic lymphadenectomy alone.

Project description:BackgroundDespite that pelvic and para-aortic lymphadenectomy (PPaLND) is recommended as part of accurate surgical staging by International Federation of Gynecology and Obstetrics (FIGO) in endometrial cancer, the impact of para-aortic lymphadenectomy on survival remains controversial. The aim of this work is to evaluate the survival benefits or risks in endometrial cancer patients who underwent surgical staging with or without para-aortic lymphadenectomy using meta-analysis.MethodsLiterature search was undertaken using PubMed, Embase, and Cochrane Library databases for relevant articles published between January 1, 1990, and January 1, 2017, without language restriction. The primary outcome was overall survival (OS); progression-free survival (PFS)/recurrence-free survival (RFS)/disease-free survival (DFS)/disease-related survival (DRS) was also analyzed. Subgroup analysis and sensitivity analysis were conducted to investigate the source of heterogeneity. Quality assessments were performed by Newcastle-Ottawa Quality Assessment Scale (NOS). Publication bias was evaluated by using Begg and Egger tests. The hazard ratio (HR) was pooled with random-effects or fixed-effects model as appropriate.ResultsEight studies with a total of 2793 patients were included. OS was significantly longer in PPaLND group than in pelvic lymphadenectomy (PLND) group for patients with endometrial cancer [HR 0.68; 95% confidence interval (CI) 0.55-0.84, P < .001, I = 12.2%]. Subgroup analysis by recurrence risk explored the same association in patients at intermediate- or high-risk (HR 0.52; 95% CI 0.39-0.69, P < .001, I = 41.4%), but not for low-risk patients (HR 0.48; 95% CI 0.21-1.08, P = .077, I = 0). PPaLND with systematic resection of all para-aortic nodes up to renal vein also improved PFS/RFS/DFS/DRS, compared with PLND (HR 0.52, 95% CI 0.37-0.72, P < .001, I = 0). No publication bias was observed among included studies.ConclusionPPaLND is associated with favorable survival outcomes in endometrial cancer patients with intermediate- or high-risk of recurrence compared with PLND, particularly with regards to OS. PPaLND with systematic resection of all para-aortic nodes up to renal vein also improve PFS compared with PLND. Further large-scale randomized clinical trials are required to validate our findings.

Project description:BackgroundRemoving more inframesenteric nodes is not only significantly increases the likelihood of finding metastasis for endometrial cancer, but also can add survival advantage. As most patients diagnosed with endometrial cancer are overweight or obesity, a high efficiency approach is important. Aim of this study was to compare the surgical outcomes of extraperitoneal laparoscopic, transperitoneal laparoscopic, and laparotomic para-aortic lymphadenectomy in endometrial carcinoma staging.MethodsWe retrospectively reviewed data of all patients diagnosed with primary endometrial carcinoma who were treated at the Department of Gynecologic Oncology, Fudan University Shanghai Cancer Center from 1 January 2017 to 31 December 2019. The numbers of para-aortic lymph nodes, surgical time, complications, blood loss and hospital stay were compared. The patients' medical records and pathological reports were carefully reviewed. Statistical significance was defined as p < 0.05.ResultsWe retrospectively compared patients who underwent extraperitoneal laparoscopy (Group E, n = 20), transperitoneal laparoscopy (group T, n = 21), and laparotomy (group L, n = 135). The median number of para-aortic lymph nodes was significantly higher in group E than in groups T and L (9.5, 5, and 6, respectively; p = 0.004 and 0.0004, respectively). All patients in group E underwent successfully dissection to the renal vessel level. The median operation time was significantly shorter in group L than in groups T and E (94, 174, and 233 min, respectively; p < 0.0001). The median estimated blood loss volume was higher in group L than in groups T and E (200, 100, and 142.5 ml, respectively; all comparisons p < 0.001), and the length of hospital stay was significantly longer in group L than in Groups T and E (6, 5, and 6 days, respectively; all comparisons p < 0.001).ConclusionThe extraperitoneal laparoscopic approach for staging endometrial carcinoma harvested higher numbers of para-aortic lymph nodes which could be considered for endometrial carcinoma staging, especially for para-aortic lymph node harvest.

Project description:Study designRetrospective cohort study.IntroductionDebates remain regarding the role of lymphadenectomy in patients with apparent stage IA endometrial cancer, especially subtypes with a favorable prognosis. This study aimed to explore the prognostic value of staging surgeries in apparent stage IA endometrial endometrioid cancer patients in a retrospective cohort study.MethodsCases from June 1, 2010 to June 1, 2017 were reviewed in patients with pathologically confirmed endometrial endometrioid carcinoma limited to <1/2 of the myometrium, without extrauterine metastasis on preoperative evaluation and during surgical inspection. Survival outcomes were compared between patients with and without lymphadenectomy and between patients with and without metastasis to lymph nodes.ResultsIn total, 1,312 eligible patients were included, among which 836 underwent staging surgeries and 476 underwent simple hysterectomy. Twenty-eight patients were found with metastasis to retroperitoneal lymph nodes. After a median follow-up of 57.4 months, lost to follow-up, recurrence, death, and cancer-specific death occurred in 28, 39, 24, and 16 patients, respectively. In a univariate analysis, lymphadenectomy of the pelvis with or without para-aortic lymph nodes had no significant impact on disease-free survival, overall survival or cancer-specific overall survival (p values >0.05). However, after adjusting for important baseline risk factors [menopausal status, tumor differentiation, maximum diameter and location, lymph-vascular space invasion (LVSI) status, and postoperative adjuvant therapy), lymphadenectomy resulted in significantly improved survival outcomes (p values <0.05). Menopause (odds ratio [OR] 4.7, 95% confidence interval [CI] 1.3-16.4, p=0.015), tumor diameter larger than 2 cm (OR 4.6, 95% CI 1.3-16.0, p=0.016), grade 3 tumors (OR 3.0, 95% CI 1.0-8.5, p=0.042), positive LVSI (OR 8.7, 95% CI 3.7-20.4, p<0.001) and lower uterine segment involvement (OR 3.1, 95% CI 1.4-7.2, p=0.007) had more extrauterine metastases.ConclusionIn cases of apparent stage IA endometrioid endometrial carcinoma, staging surgeries should be considered in patients with larger, higher grade tumors, positive LVSI, or lower uterine segment involvement.
