- Pattern of relapse in patients with stage IB1 cervical cancer after radical hysterectomy as primary treatment. Minimally invasive surgery vs. open approach. Systematic review and meta-analysis.(Elsevier, 2022) Chacón, E. (Enrique); Minguez, J.A. (José Ángel); Alcazar, J.L. (Juan Luis); Boria, F. (Félix); Chiva, L. (Luis); Rodriguez-Velandia, Y.P. (Yessica P.); Vara-García, J. (Julio); Manzour, N. (Nabil); Nuñez-Cordoba, J.M. (Jorge M.)Background. After the LACC trial, the SUCCOR study, and other studies, we know that patients who have un- dergone minimally invasive surgery for cervical cancer have worse outcomes, but today, we do not know if the surgical approach can be a reason to change the pattern of relapses on these patients. We evaluated the relapse pattern in patients with stage IB1 cervical cancer (FIGO, 2009) who underwent radical hysterectomy with differ- ent surgical approaches. Methods. A systematic review of literature was performed in PubMed, Cochrane Library, Clinicaltrials.gov, and Web of science. Inclusion criteria were prospective or retrospective comparative studies of different surgical approaches that described patterns or locations of relapse in patients with stage IB1 cervical cancer. Heterogeneity was assessed by calculating I2. Results. The research resulted in 782 eligible citations from January 2010 to October 2020. After filtering, nine articles that met all inclusion criteria were analyzed, comprising data from 1663 patients who underwent radical hysterectomy for IB1 cervical cancer, and the incidence of relapse was 10.6%. When we compared the pattern of relapse (local, distant, and both) of each group (open surgery and minimally invasive surgery), we did not see statistically significant differences, (OR 0.963; 95% CI, 0.602–1.541; p = 0.898), (OR 0.788; 95% CI, 0.467–1.330; p = 0.542), and (OR 0.683; 95% CI, 0.331–1.407; p = 0.630), respectively. Conclusion. There are no differences in patterns of relapse across surgical approaches in patients with stage IB1 cervical cancer undergoing radical hysterectomy as primary treatment.
- SUCCOR risk: design and validation of a recurrence prediction index for early-stage cervical cancer(2022) Chacón, E. (Enrique); Minguez, J.A. (José Ángel); Martin-Calvo, N. (Nerea); Alcazar, J.L. (Juan Luis); Boria, F. (Félix); Chiva, L. (Luis); Manzour, N. (Nabil)Objective Based on the SUCCOR study database, our primary objective was to identify the independent clinical pathological variables associated with the risk of relapse in patients with stage IB1 cervical cancer who underwent a radical hysterectomy. Our secondary goal was to design and validate a risk predictive index (RPI) for classifying patients depending on the risk of recurrence. Methods Overall, 1116 women were included from January 2013 to December 2014. We randomly divided our sample into two cohorts: discovery and validation cohorts. The test group was used to identify the independent variables associated with relapse, and with these variables, we designed our RPI. The index was applied to calculate a relapse risk score for each participant in the validation group. Results A previous cone biopsy was the most significant independent variable that lowered the rate of relapse (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.17-0.60). Additionally, patients with a tumor diameter >2 cm on preoperative imaging assessment (OR 2.15, 95% CI 1.33-3.5) and operated by the minimally invasive approach (OR 1.61, 95% CI 1.00-2.57) were more likely to have a recurrence. Based on these findings, patients in the validation cohort were classified according to the RPI of low, medium, or high risk of relapse, with rates of 3.4%, 9.8%, and 21.3% observed in each group, respectively. With a median follow-up of 58 months, the 5-year disease-free survival rates were 97.2% for the low-risk group, 88.0% for the medium-risk group, and 80.5% for the high-risk group (p < 0.001). Conclusion Previous conization to radical hysterectomy was the most powerful protective variable of relapse. Our risk predictor index was validated to identify patients at risk of recurrence.
- SUCCOR Nodes: May Sentinel Node Biopsy Determine the Need for Adjuvant Treatment?(Springer, 2023) Chacón, E. (Enrique); Martin-Calvo, N. (Nerea); Bizzarri, N. (Nicolò); Boria, F. (Félix); Chiva, L. (Luis); Manzour, N. (Nabil); Berasaluce, A. (Arantxa)Background The SUCCOR cohort was developed to analyse the overall and disease-free survival at 5 years in women with FIGO 2009 stage IB1 cervical cancer. The aim of this study was to compare the use of adjuvant therapy in these women, depending on the method used to diagnose lymphatic node metastasis. Patients and Methods We used data from the SUCCOR cohort, which collected information from 1049 women with FIGO 2009 stage IB1 cervical cancer who were operated on between January 2013 and December 2014 in Europe. We calculated the adjusted proportion of women who received adjuvant therapy depending on the lymph node diagnosis method and compared disease free and overall survival using Cox proportional-hazards regression models. Inverse probability weighting was used to adjust for baseline potential confounders. Results The adjusted proportion of women who received adjuvant therapy was 33.8% in the sentinel node biopsy + lymphadenectomy (SNB+LA) group and 44.7% in the LA group (p = 0.02), although the proportion of positive nodal status was similar (p = 0.30). That difference was greater in women with negative nodal status and positive Sedlis criteria (difference 31.2%, p = 0.01). Here, those who underwent a SNB+LA had an increased risk of relapse [hazard ratio (HR) 2.49, 95% confidence interval (CI) 0.98–6.33, p = 0.056] and risk of death (HR 3.49, 95% CI 1.04–11.7, p = 0.042) compared with those who underwent LA. Conclusions Women in this study were less likely to receive adjuvant therapy if their nodal invasion was determined using SNB+LA compared with LA. These results suggest a lack of therapeutic measures available when a negative result is obtained by SNB+LA, which may have an impact on the risk of recurrence and survival.
- 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) predictive score for complete resection in primary cytoreductive surgery(2022) Boria, F. (Félix); Chiva, L. (Luis); Sin Autoridad; Gutierrez, M. (Monica); Sancho-Rodriguez, L. (Lidia); Alcázar, A. (Andrés); Zapardiel, I. (Ignacio)Objective To assess the value of preoperative 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) scan, combined with clinical variables, in predicting complete cytoreduction in selected patients with advanced ovarian cancer. Methods We carried out a multicenter, observational, retrospective study evaluating patients who underwent primary cytoreductive surgery for advanced ovarian cancer in two Spanish centers between January 2017 and January 2022. Inclusion criteria were histological confirmation of invasive epithelial ovarian carcinoma; preoperative International Federation of Gynecology and Obstetrics (FIGO) stage III or IV; upfront cytoreductive surgery; and 18F-FDG PET/CT performed 1 month prior to surgery. A modified 18F-FDG PET/CT peritoneal cancer index score was calculated for all patients. Clinical variables and preoperative 18F-FDG PET/CT findings were analyzed and a multivariate model was constructed. A predictive score based on the odds ratio of the variables was calculated to determine patient selection. Results A total of 45 patients underwent primary cytoreductive surgery. Complete resection was achieved in 36 (80%) patients. On multivariate analysis, two clinical variables (age ≥58 years and American Society of Anesthesiology score ≥3) and two preoperative 18F-FDG PET/CT scan findings (presence of extra-abdominal lymph node involvement and modified peritoneal cancer index value of 6 or more) were associated with gross residual disease. For this multivariate model predictive of non-complete cytoreduction, the area under the curve was 0.881. A predictive value of ≥5 was the most predictive cut-off for gross residual disease. Complete resection rate was 91.7% in patients with a score of ≤4 and 33.3% in patients with a score of ≥5 points on the predictive score. Conclusions In selected patients, a predictive score value ≥5 may be consider as a cut-off point for triaging patients to diagnostic laparoscopy before the primary surgery or neoadjuvant chemotherapy.
