Intraperitoneal cytology after laparoscopic hysterectomy in patients with endometrial cancer: A retrospective observational study

Range of Resection in Endometrial Cancer-Clinical Issues of Made-to-Measure Surgery

Endometrial cancer (EC) poses a significant health issue among women, and its incidence has been rising for a couple of decades. Surgery remains its principal treatment method and may have a curative, staging, or palliative aim. The type and extent of surgery depends on many factors, and the risks and benefits should be carefully weighed. While simple hysterectomy might be sufficient in early stage EC, modified-radical hysterectomy is sometimes indicated. In advanced disease, the evidence suggests that, similarly to ovarian cancer, optimal cytoreduction improves survival rate. The role of lymphadenectomy in EC patients has long been a controversial issue. The rationale for systematic lymphadenectomy and the procedure of the sentinel lymph node biopsy are thoroughly discussed. Finally, the impact of the molecular classification and new International Federation of Gynecology and Obstetrics (FIGO) staging system on EC treatment is outlined. Due to the increasing knowledge on the pathology and molecular features of EC, as well as the new advances in the adjuvant therapies, the surgical management of EC has become more complex. In the modern approach, it is essential to adjust the extent of the surgery to a specific patient, ensuring an optimal, made-to-measure personalized surgery. This narrative review focuses on the intricacies of surgical management of EC and aims at summarizing the available literature on the subject, providing an up-to-date clinical guide.

Oncologic outcomes for patients with endometrial cancer who received minimally invasive surgery: a retrospective observational study

BACKGROUND

Laparoscopic hysterectomy has been performed for patients with endometrial cancer as minimally invasive surgery; however, the long-term outcomes of high-risk disease compared to open surgery remain unclear.

METHODS

Eight hundred and eighty-three patients with endometrial cancer who underwent laparoscopic or abdominal hysterectomy were categorized into three groups. Low-risk disease was defined as stage IA disease with endometrioid carcinoma of grade 1 or 2. Uterine-confined disease was defined as stage IA disease with high-grade tumors or stage IB and II disease. Advanced disease was defined as stage III or IV disease. The progression-free survival (PFS) and overall survival (OS) rates were compared between laparoscopic and laparotomic hysterectomy.

RESULTS

Among 478 patients with low-risk disease, including 226 with laparoscopy and 252 with laparotomy, the prognosis was not significantly different between the groups (3-year PFS rate, 97.4% vs. 97.1%, p = 0.8; 3-year OS rate, 98.6% vs. 98.3%, p = 0.9). Among the 229 patients with uterine-confined disease, including 51 with laparoscopy and 178 with laparotomy, the prognosis was not significantly different between the groups (3-year PFS rate, 90.5% vs. 85.5%, p = 0.7; 3-year OS rate, 91.3% vs. 92.5%, p = 0.8). Among the 176 patients with advanced disease, including 24 with laparoscopy and 152 with laparotomy, laparoscopic hysterectomy had a higher PFS rate and OS rate than laparotomic hysterectomy (3-year PFS rate, 74.5% vs. 51.5%, p = 0.01; 3-year OS rate, 92.3% vs. 75.1%, p = 0.03).

CONCLUSIONS

Laparoscopic procedures are not associated with a poorer outcome than laparotomy in patients with advanced endometrial cancer or uterine-confined endometrial cancer.

Current recommendations and recent progress in endometrial cancer

Endometrial cancer is the most common gynecologic cancer in the United States, and its incidence is rising. Although there have been significant recent advances in our understanding of endometrial cancer biology, many aspects of treatment remain mired in controversy, including the role of surgical lymph node assessment and the selection of patients for adjuvant radiation or chemotherapy. For the subset of women with microsatellite-instable, metastatic disease, anti- programmed cell death protein 1 immunotherapy (pembrolizumab) is now approved by the US Food and Drug Administration, and numerous trials are attempting to build on this early success.

Does tumour effraction during robotic partial nephrectomy have any impact on recurrence?

OBJECTIVE

To evaluate the impact of accidental surgical incision into the tumour (ASIT) on oncological outcomes in patients undergoing RPN for a malignant tumour.

MATERIALS AND METHODS

A retrospective review of our prospectively maintained database was performed to identify all patients who underwent RPN for a localized RCC between June 2010 and July 2016. We stratified our cohort into two groups according to the presence of an ASIT. Perioperative data were compared between the two groups. Logistic regression analyses were used to assess the variables associated with ASIT. Recurrence-free survival was estimated using the Kaplan-Meier method and compared between groups with the log-rank test.

RESULTS

A total of 234 patients were identified. 32 (14%) ASIT were observed. Patients' characteristics were similar in the two groups. Most of intraoperative outcomes were comparable between the two groups, but patients in the ASIT group had greater EBL (475 vs. 300 mL; p = 0.01). In multivariate analysis, tumour size (p = 0.02), RENAL score (p = 0.02), EBL (p = 0.05) and low surgeon experience (p = 0.03) were all predictive factors of ASIT. 15 (6%) of recurrences were observed over a median follow-up of 36 months. There was no difference in recurrence-free survival between the two groups (p = 0.57).

CONCLUSIONS

In our experience, accidental surgical incision into the tumour during RPN was a common event that did not appear to compromise oncological outcome.
