Patient-reported outcomes after surgery for endometrial carcinoma: Prevalence of lower-extremity lymphedema after sentinel lymph node mapping versus lymphadenectomy.

ABSTRACT:

Objective

To compare the prevalence of patient-reported lower-extremity lymphedema (LEL) with sentinel lymph node (SLN) mapping versus comprehensive lymph node dissection (LND) for the surgical management of newly diagnosed endometrial carcinoma.

Methods

Patients who underwent primary surgery for endometrial cancer from 01/2006-12/2012 were mailed a survey that included a validated 13-item LEL screening questionnaire in 08/2016. Patients diagnosed with LEL prior to surgery and those who answered ?6 survey items were excluded.

Results

Of 1275 potential participants, 623 (49%) responded to the survey and 599 were evaluable (180 SLN, 352 LND, 67 hysterectomy alone). Median BMI was similar among cohorts (P = 0.99). External-beam radiation therapy (EBRT) was used in 10/180 (5.5%) SLN and 35/352 (10%) LND patients (P = 0.1). Self-reported LEL prevalence was 27% (49/180) and 41% (144/352), respectively (OR, 1.85; 95% CI, 1.25-2.74; P = 0.002). LEL prevalence was 51% (23/45) in patients who received EBRT and 35% (170/487) in those who did not (OR, 1.95; 95% CI, 1.06-3.6; P = 0.03). High BMI was associated with increased prevalence of LEL (OR, 1.04; 95% CI, 1.02-1.06; P = 0.001). After controlling for EBRT and BMI, LND retained independent association with an increased prevalence of LEL over SLN (OR, 1.8; 95% CI, 1.22-2.69; P = 0.003). Patients with self-reported LEL had significantly worse QOL compared to those without self-reported LEL.

Conclusions

This is the first study to assess patient-reported LEL after SLN mapping for endometrial cancer. SLN mapping was independently associated with a significantly lower prevalence of patient-reported LEL. High BMI and adjuvant EBRT were associated with an increased prevalence of patient-reported LEL.

Project description:ImportanceWhether sentinel lymph node biopsy (SLNB) can replace lymphadenectomy for surgical staging in patients with high-grade endometrial cancer (EC) is unclear.ObjectiveTo examine the diagnostic accuracy of, performance characteristics of, and morbidity associated with SLNB using indocyanine green in patients with intermediate- and high-grade EC.Design, setting, and participantsIn this prospective, multicenter cohort study (Sentinel Lymph Node Biopsy vs Lymphadenectomy for Intermediate- and High-Grade Endometrial Cancer Staging [SENTOR] study), accrual occurred from July 1, 2015, to June 30, 2019, with early stoppage because of prespecified accuracy criteria. The study included patients with clinical stage I grade 2 endometrioid or high-grade EC scheduled to undergo laparoscopic or robotic hysterectomy with an intent to complete staging at 3 designated cancer centers in Toronto, Ontario, Canada.ExposuresAll patients underwent SLNB followed by lymphadenectomy as the reference standard. Patients with grade 2 endometrioid EC underwent pelvic lymphadenectomy (PLND) alone, and patients with high-grade EC underwent PLND and para-aortic lymphadenectomy (PALND).Main outcomes and measuresThe primary outcome was sensitivity of the SLNB algorithm. Secondary outcomes were additional measures of diagnostic accuracy, sentinel lymph node detection rates, and adverse events.ResultsThe study enrolled 156 patients (median age, 65.5 years; range, 40-86 years; median body mass index [calculated as weight in kilograms divided by height in meters squared], 27.5; range, 17.6-49.3), including 126 with high-grade EC. All patients underwent SLNB and PLND, and 101 patients (80%) with high-grade EC also underwent PALND. Sentinel lymph node detection rates were 97.4% per patient (95% CI, 93.6%-99.3%), 87.5% per hemipelvis (95% CI, 83.3%-91.0%), and 77.6% bilaterally (95% CI, 70.2%-83.8%). Of 27 patients (17%) with nodal metastases, 26 patients were correctly identified by the SLNB algorithm, yielding a sensitivity of 96% (95% CI, 81%-100%), a false-negative rate of 4% (95% CI, 0%-19%), and a negative predictive value of 99% (95% CI, 96%-100%). Only 1 patient (0.6%) was misclassified by the SLNB algorithm. Seven of 27 patients with node-positive cancer (26%) were identified outside traditional PLND boundaries or required immunohistochemistry for diagnosis.Conclusions and relevanceIn this prospective cohort study, SLNB had acceptable diagnostic accuracy for patients with high-grade EC at increased risk of nodal metastases and improved the detection of node-positive cases compared with lymphadenectomy. The findings suggest that SLNB is a viable option for the surgical staging of EC.

Project description:ObjectiveTo evaluate the utility of sentinel lymph node mapping (SLN) in endometrial cancer (EC) patients in comparison with lymphadenectomy (LND).MethodsComprehensive search was performed in MEDLINE, EMBASE, CENTRAL, OVID, Web of science databases, and three clinical trials registration websites, from the database inception to September 2020. The primary outcomes covered operative outcomes, nodal assessment, and oncological outcomes. Software Revman 5.3 was used. Trial sequential analysis (TSA) and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) were performed.ResultsOverall, 5,820 EC patients from 15 studies were pooled in the meta-analysis: SLN group (N = 2,152, 37.0%), LND group (N = 3,668, 63.0%). In meta-analysis of blood loss, SLN offered advantage over LND in reducing operation bleeding (I2 = 74%, P<0.01). Z-curve of blood loss crossed trial sequential monitoring boundaries though did not reach TSA sample size. There was no difference between SLN and LND in intra-operative complications (I2 = 7%, P = 0.12). SLN was superior to LND in detecting positive pelvic nodes (P-LN) (I2 = 36%, P<0.001), even in high risk patients (I2 = 36%, P = 0.001). While no difference was observed in detection of positive para-aortic nodes (PA-LN) (I2 = 47%, P = 0.76), even in high risk patients (I2 = 62%, P = 0.34). Analysis showed no difference between two groups in the number of resected pelvic nodes (I2 = 99%, P = 0.26). SLN was not associated with a statistically significant overall survival (I2 = 79%, P = 0.94). There was no difference in progression-free survival between SLN and LND (I2 = 52%, P = 0.31). No difference was observed in recurrence. Based on the GRADE assessment, we considered the quality of current evidence to be moderate for P-LN biopsy, low for items like blood loss, PA-LN positive.ConclusionThe present meta-analysis underlines that SLN is capable of reducing blood loss during operation in regardless of surgical approach with firm evidence from TSA. SLN mapping is more targeted for less node dissection and more detection of positive lymph nodes even in high risk patients with conclusive evidence from TSA. Utility of SLN yields no survival detriment in EC patients.
