ABSTRACT
Objective@#To evaluate the efficacy and safety of systematic lymph node dissection (SyLND) at the time of interval debulking surgery (IDS) for advanced epithelial ovarian cancer (AEOC). @*Methods@#Systematic literature review of studies including AEOC patients undergoing SyLND versus selective lymph node dissection (SeLND) or no lymph node dissection (NoLND) after neoadjuvant chemotherapy (NACT). Primary endpoints included progression-free survival (PFS) and overall survival (OS). Secondary endpoints included severe postoperative complications, lymphocele, lymphedema, blood loss, blood transfusions, operative time, and hospital stay. @*Results@#Nine retrospective studies met the eligibility criteria, involving a total of 1,660 patients: 827 (49.8%) SyLND, 490 (29.5%) SeLND, and 343 (20.7%) NoLND. The pooled estimated hazard ratios (HR) for PFS and OS were, respectively, 0.88 (95% confidence interval [CI]=0.65–1.20; p=0.43) and 0.80 (95% CI=0.50–1.30; p=0.37). The pooled estimated odds ratios (ORs) for severe postoperative complications, lymphocele, lymphedema, and blood transfusions were, respectively, 1.83 (95% CI=1.19–2.82; p=0.006), 3.38 (95% CI=1.71–6.70; p<0.001), 7.23 (95% CI=3.40–15.36; p<0.0001), and 1.22 (95% CI=0.50–2.96; p=0.67). @*Conclusion@#Despite the heterogeneity in the study designs, SyLND after NACT failed to demonstrate a significant improvement in PFS and OS and resulted in a higher risk of severe postoperative complications.
ABSTRACT
Objective@#To investigate current evidence on oncological, fertility and obstetric outcomes of patients with stage I cervical cancer of 4 cm or larger undergoing fertility-sparing surgery (FSS). @*Methods@#Systematic review of studies including women affected by stage I cervical cancer ≥4 cm who underwent FSS. Main outcome measures: disease-free survival (DFS), overall survival (OS), pregnancy rate, live birth rate, premature delivery rate. @*Results@#Fifteen studies met all eligibility criteria for this systematic review, involving 48 patients affected by cervical cancer ≥4 cm who completed FSS. Three patients (6.3%) experienced a recurrence and one of them (2.1%) died of disease. The 5-year DFS rate was 92.4%. The 5-year OS rate was 97.6%. A significantly shorter 5-year DFS was reported for high-risk patients (G3, non-squamous histotype, diameter ≥5 cm) compared with low-risk (74.7% vs. 100%; log-rank test, p=0.024). Data about fertility outcomes were available for 12 patients. Five patients out of 12 (41.7%) attempted to conceive with an estimated pregnancy rate of 80%, a live birth rate of 83.3% and a premature delivery rate of 20%. @*Conclusion@#Women with high tumor grade, aggressive histology and tumor size ≥5 cm have a higher risk of recurrence. Oncologic outcomes are encouraging among low-risk patients; however, the lack of high-quality studies makes it difficult to draw any firm conclusions. Prospective multicentric clinical trials with a proper selection of inclusion/exclusion criteria should be conducted in women with low-risk factors, strong desire to preserve their fertility and high likelihood to conceive.
