Molecular profile in endometrial carcinoma: can we predict the lymph node status? A systematic review and meta-analysis.

PURPOSE: Molecular classification of endometrial cancer (EC) has become a promising information to tailor preoperatively the surgical treatment. We aimed to evaluate the rate of lymph node metastases (LNM) in patients with EC according to molecular profile. METHODS: A systematic review and meta-analysis were performed according to PRISMA guidelines by searching in two major electronic databases (PubMed and Scopus), including original articles reporting lymph node metastases according to the molecular classification of EC as categorized in the ESGO-ESMO-ESP guidelines. RESULTS: Fifteen studies enrolling 3056 patients were included. Pooled prevalence LNM when considering only patients undergoing lymph node assessment was 4% for POLE-mutated (95%CI: 0-12%), 22% for no specific molecular profile (95% CI: 9-39%), 23% for Mismatch repair-deficiency (95%CI: 10-40%) and 31% for p53-abnormal (95%CI: 24-39%). CONCLUSIONS: The presence of LNM seems to be influenced by molecular classification. P53-abnormal group presents the highest rate of nodal involvement, and POLE-mutated the lowest.

Discontinuation of mechanical bowel preparation in advanced ovarian cancer surgery: an enhanced recovery after surgery (ERAS) initiative.

OBJECTIVE: To investigate the impact of discontinuation of mechanical bowel preparation in advanced ovarian cancer surgery within the context of the ERAS program. METHODS: We retrospectively reviewed the medical records of patients with advanced ovarian cancer who underwent cytoreductive surgery with simultaneous colon and/or rectal resection from January 2012 to November 2020. Patients were divided into two groups based on whether preoperative mechanical bowel preparation (MBP) was given (pre-ERAS) or not (post-ERAS). Patient characteristics, including duration of antibiotic treatment, surgical complexity, and incidence of surgical and nonsurgical complications, were compared. RESULTS: During the study period, 114 patients who underwent colon and/or rectal resection were examined, of whom 39 received MBP and 75 did not receive MBP (NMBP). On comparison between the two groups, no significant differences were noted in the assessed patient characteristics, including mean age, FIGO stage, ASA class, BMI, or residual tumor. One patient (2.6%) in the MBP group, and 4 patients (5.3%) in the NMBP group experienced an anastomotic leakage (p = 0.11). No significant differences were found with respect to surgical site infection. (p = 0.5). CONCLUSION: MBP was not associated with any specific benefit for advanced ovarian cancer surgery. Gynecologic oncologists who use MBP should consider discontinuing this practice.

Adjuvant therapy in early-stage cervical cancer after radical hysterectomy: are we overtreating our patients? A meta-analysis.

OBJECTIVE: There is a gap in knowledge regarding the ideal management of patients with early-stage cervical cancer and intermediate-risk features. Here, we present a meta-analysis of the published literature on oncological outcomes in these patients and determine trends in postoperative management. METHODS: MEDLINE and PubMed were used for literature searches. The inclusion criteria were: English language articles including ≥ 10 patients, patients who underwent radical hysterectomy, nodes negative, studies reporting oncological outcomes and complications treatment-related and compare a surgery-only cohort with a radiotherapy cohort. The PRISMA guidelines were followed. Combined relative risk was calculated using DerSimonian-Laird random-effects model and a forest plot was drawn. RESULTS: We collected 183 manuscripts on early-stage cervical cancer treated with radical hysterectomy alone or with adjuvant radiotherapy after surgery. A total of eight studies met the inclusion criteria. Regarding oncological outcomes, survival was reported in five studies. The relative risk of recurrence and the relative risk of mortality was similar in both groups independently whether receive or not adjuvant therapy. Most of the studies did not report significant differences regarding morbidity treatment related between the groups, except for a higher rate of lymphedema after radiotherapy. CONCLUSION: We found that the relative risk of recurrence and mortality was similar in both groups not depending on adjuvant therapy. Therefore, whether radiotherapy adjuvant treatment is indicated remains a topic of debate.

Role of Indocyanine Green in Sentinel Node Mapping in Gynecologic Cancer: Is Fluorescence Imaging the New Standard?

Sentinel lymph node biopsy has proven safe and feasible in a number of gynecologic cancers such as vulvar cancer, cervical cancer, and endometrial cancer. The proposed aim of lymphatic mapping and sentinel node identification is to decrease the associated morbidity of a complete lymphadenectomy, particularly the rate of lymphedema, while also increasing the detection of small tumor deposits in the node. Different tracers have been shown to be useful, including technetium-99 and blue dye, with a detection reported in 66% to 86%. Recently, there has been increasing interest in the use of fluorescent dies such as indocyanine green (ICG). In this report we provide a review of the existing literature regarding the use of ICG in cervical or endometrial cancer with the goal to provide details on its utility and compare it with other tracers.
