Objective: Lower extremity lymphedema adversely affects quality of life by causing discomfort, impaired mobility and increased risk of infection. The goal of this study is to investigate factors that influence the likelihood of lymphedema in patients with endometrial cancer who undergo adjuvant radiation with or without chemotherapy. Methods: A retrospective chart review identified all stage I-III endometrial cancer patients who had a hysterectomy with or without complete staging lymphadenectomy and adjuvant radiation therapy between January 2006 and February 2013. Patients with new-onset lymphedema after treatment were identified. Logistic regression was used to find factors that influenced lymphedema risk. Results: Of 212 patients who met inclusion criteria, 15 patients (7.1%) developed new-onset lymphedema. Lymphedema was associated with lymph-node dissection (odds ratio [OR], 5.6; 95% CI, 1.01 to 105.5; p=0.048) and with the presence of pathologically positive lymph nodes (OR, 4.1; 95% CI, 1.4 to 12.3; p=0.01). Multivariate logistic regression confirmed the association with lymph-node positivity (OR, 3.2; 95% CI, 1.0007 to 10.7; p=0.0499) when controlled for lymph-node dissection. Median time to lymphedema onset was 8 months (range, 1 to 58 months) with resolution or improvement in eight patients (53.3%) after a median of 10 months. Conclusion: Lymph-node positivity was associated with an increased risk of lymphedema in endometrial cancer patients who received adjuvant radiation. Future studies are needed to explore whether node-positive patients may benefit from early lymphedema-controlling interventions. [ABSTRACT FROM AUTHOR]

Background and purpose The goals of this study were to determine the rate and risk factors of rectal bleeding (RB) after external beam radiotherapy and vaginal brachytherapy (EBRT + VB), and to compare these data to previously unreported RB rates from PORTEC-2 patients receiving EBRT or VB alone. Materials and methods Retrospective chart review identified 212 endometrial cancer patients receiving adjuvant EBRT + VB between 2006 and 2013. Patient-reported RB data were also obtained from PORTEC-2 patients randomized to EBRT ( n = 166) or VB ( n = 182). The two populations were compared using an RB scale of symptom severity. Results After a median 35 months, 17.9% of EBRT + VB patients ( n = 38) experienced any RB with 1.9% ( n = 4) having bleeding requiring intervention. Age ⩽70 years was the only predictor of RB (OR 2.8; 95% CI 1.1–8.7; p = 0.027). Rates of patient-reported RB after EBRT were similar with 15.0% ( n = 25) having any RB and 0.6% ( n = 1) having “very much” bleeding. On regression analysis, any EBRT (either EBRT alone or EBRT + VB) increased the risk of RB compared to those who received VB alone (OR 3.0; p = 0.0028; 95% CI 1.4–6.7). The rates of more severe RB were low and did not significantly differ between treatments. Conclusions Significant RB is rare after radiation. EBRT has higher rates of rectal bleeding than VB. The addition of VB to EBRT does not significantly alter bleeding rates. [ABSTRACT FROM AUTHOR]
