Laparoscopic vs. robotic-assisted laparoscopy in endometrial cancer staging: large retrospective singleinstitution study / 부인종양

Objective@#The aim of this study is to analyze and draw the potential differences between the robotic-assisted surgery (RS) and the laparoscopy (LPS) in endometrial cancer staging. @*Methods@#In this single-institution retrospective study we enrolled 1,221 consecutive clinical stage I–III endometrial cancer patients undergone minimally invasive surgical staging. We compared patients treated by LPS and by RS, on the basis of perioperative and oncological outcomes (disease-free survival [DFS] and overall survival [OS]). A sub-analysis of the highrisk endometrial cancer population was performed in the 2 cohorts. @*Results@#The 2 cohorts (766 treated by LPS and 455 by RS) were homogeneous in terms of perioperative and pathological data. We recorded differences in number of relapse/ progression (11.7% in LPS vs. 7% in RS, p=0.008) and in number of deaths (9.8% in LPS vs. 4.8% in RS, p=0.002). Whereas, univariate and multivariate analyses according to DFS and OS confirmed that the surgical approach did not influence the DFS or the OS. In the multivariable analysis the association of the age and grading was significant for DFS and OS. In the sub-analysis of the 426 high risk EC patients (280 in LPS and 146 in RS) the univariate and the multivariate confirmed the influence of the age in DFS and OS, independently of the minimally invasive approach. @*Conclusions@#In our large retrospective analysis, we confirmed that the RS and LPS have similar efficacy and safety for endometrial cancer staging also for the high-risk endometrial cancer patients.

Substantial lymph-vascular space invasion (LVSI) as predictor of distant relapse and poor prognosis in low-risk early-stage endometrial cancer / 부인종양

Objective@#The aim of this study is to analyze the prognostic role of lymph-vascular space invasion (LVSI), evaluated in a semi-quantitative fashion on prognosis of early stage, low risk endometrial cancer (EC). @*Methods@#We enrolled patients who underwent surgery for endometrial cancer between 2003 and 2018 in two referral cancer center. All patients had endometrioid EC, G1–G2, with myometrial invasion <50%, and no lymph-node involvement. LVSI was analyzed in a semiquantitative way, according to a 3-tiered scoring system in absent, focal and substantial. @*Results@#Among 524 patients, any positive LVSI was found in 57 patients (10.9%) with focal LVSI (n=35, 6.7%) and substantial LVSI (n=22, 4.2%). Substantial LVSI was associated to higher rate of G2 (p<0.001), myometrial infiltration (p=0.002) and greater tumor dimensions (p=0.014). Patients with substantial LVSI were more likely to receive adjuvant treatment (6.6% vs. 52.6%, p<0.001). The 5-year OS was 99.5% in patients with absent LVSI and 70.6% in those with substantial LVSI (p<0.001). The 5-year disease free survival (DFS) was 93.6% in patients with absent LVSI and 56.5% in those with substantial LVSI (p<0.001). The rate of distant failures increased from 1.8% for absent LVSI to 22.7% for substantial LVSI (p=0.002). In univariate analysis substantial LVSI was the strongest predictor of poor overall survival (hazard ratio [HR]=11.9, p=0.001). Multivariate analysis showed that substantial LVSI was an independent predictive factor of both recurrence (HR=5.88, p=0.001) and distant failure (HR=10.6, p=0.006). @*Conclusions@#Substantial LVSI represents the strongest independent risk factor for decreased survival and distant relapse, indicating a role for potential hematogenous dissemination.

Survival in clinical stage I endometrial cancer with single vs. multiple positive pelvic nodes: results of a multi-institutional Italian study / 부인종양

OBJECTIVE: To investigate survival outcomes in endometrioid endometrial cancer (EEC) patients with single vs. multiple positive pelvic lymph nodes. METHODS: We performed a retrospective evaluation of all consecutive patients with histologically proven International Federation of Gynecology and Obstetrics (FIGO) stage IIIC1 EEC who underwent primary surgical treatment between 2004 and 2014 at seven Italian gynecologic oncology referral centers. Patients with pre- or intra-operative evidence of extra-uterine disease (including the presence of bulky nodes) and patients with stage IIIC2 disease were excluded, in order to obtain a homogeneous population. RESULTS: Overall 140 patients met the inclusion criteria. The presence of >1 metastatic pelvic node was significantly associated with an increased risk of recurrence and mortality, compared to only 1 metastatic node, at both univariate (recurrence: hazard ratio [HR]=2.19; 95% confidence interval [CI]=1.2–3.99; p=0.01; mortality: HR=2.8; 95% CI=1.24–6.29; p=0.01) and multivariable analysis (recurrence: HR=1.91; 95% CI=1.02–3.56; p=0.04; mortality: HR=2.62; 95% CI=1.13–6.05; p=0.02) and it was the only independent predictor of prognosis in this subset of patients. Disease-free survival (DFS) and disease-specific survival (DSS) were significantly longer in patients with only 1 metastatic node compared to those with more than 1 metastatic node (p=0.008 and 0.009, respectively). CONCLUSION: The presence of multiple metastatic nodes in stage IIIC1 EEC represents an independent predictor of worse survival, compared to only one positive node. Our data suggest that EEC patients may be categorized according to the number of positive nodes.

Preoperative chemoradiotherapy in locally advanced cervical cancer: long-term outcome and complications.

OBJECTIVE: To demonstrate the efficacy and feasibility of preoperative chemoradiotherapy in a consecutive series of 100 locally advanced cervical cancer (LACC) patients. METHODS: Between October 1997 and December 2004, 100 LACC patients were consecutively staged and treated at the Catholic University of the Sacred Heart of Rome. Radiotherapy was administered to the whole pelvic region (1.8 Gy/day, totaling 39.6 Gy) in combination with cisplatin (20 mg/m(2)) and 5-FU (1000 mg/m(2)) (both on days 1-4 and 27-30). Radical surgery was performed 5-6 weeks after the end of the treatment. RESULTS: A clinical complete or partial response was observed in 96 patients (56 and 40, respectively). Radical surgery was performed in 95 patients and an overall complication rate of 12.6% was observed in the early postoperative time. At pathological examination, 43 of 95 patients (45.2%) undergoing radical surgery showed complete response to treatment, 28 patients (29.5%) only had a microscopic disease, 18 patients (19%) had a partial response and 6 (6.3%) had no change of disease. With a median follow-up time of 25 months, the 5-year disease-free survival was 76% and the 5-year overall survival was 78%. CONCLUSIONS: These data confirm the possibility of achieving encouraging rates of local control and OS in LACC patients submitted to chemoradiation plus surgery, with a low rate of toxicity and complications.
