OBJECTIVE: To report the outcome of SLN staging in the SENTIX international prospective trial of SLN biopsy in patients with cervical cancer with an intensive ultrastaging protocol and central quality control and to evaluate how the intensity of pathological assessment correlates with metastatic detection rate in SLNs. METHODS: Eligible were patients with stages T1a1/LVSI+ to T1b2 (<4 cm, ≤2 cm for fertility sparing), common tumor types, no suspicious lymph nodes on imaging, and bilateral SLN detection. SLNs were examined intraoperatively and processed by an intensive protocol for ultrastaging (paraffin blocks sectioned completely in 150-μm intervals/levels). SLNs from each site were submitted for central quality control. RESULTS: In the SENTIX SLN study, 647 out of 733 enrolled patients underwent SLN ultrastaging, identifying 12.5% (81/647) with node positive, N1 cases. Intraoperative detection revealed metastases in 56.8% (46/81) of these cases, categorized into macrometastases (83.7%), micrometastases (26.3%), and isolated tumor cells (9.1%). Ultrastaging identified additional metastatic involvement in 43.2% (35/81) of patients, with detailed sectioning revealing metastases (MAC/MIC) at first level in 20 cases (24.7%), at levels 2-4 in 9 cases (11.1%), and at level ≥5 in 6 cases (7.4%). CONCLUSION: SLN ultrastaging detects additional 43% of N1 (MAC/MIC) in patients with negative LNs by imaging and intraoperative pathological assessment. The detection rate of positive SLN correlates with the intensity (number of levels) of ultrastaging. Examination of four levels from paraffin blocks, which detects >90% of patients with N1, is a reasonable compromise for an international standard for ultrastaging.

OBJECTIVE: Voiding dysfunctions represent a leading morbidity after radical hysterectomy performed in patients with early-stage cervical cancer. The aim of this study was to perform ad hoc analysis of factors influencing voiding recovery in SENTIX (SENTinel lymph node biopsy in cervIX cancer) trial. METHODS: The SENTIX trial (47 sites, 18 countries) is a prospective study on sentinel lymph node biopsy without pelvic lymphadenectomy in patients with early-stage cervical cancer. Overall, the data of 300 patients were analysed. Voiding recovery was defined as the number of days from surgery to bladder catheter/epicystostomy removal or to post-voiding urine residuum ≤50 mL. RESULTS: The median voiding recovery time was three days (5th-95th percentile: 0-21): 235 (78.3%) patients recovered in <7 days and 293 (97.7%) in <30 days. Only seven (2.3%) patients recovered after >30 days. In the multivariate analysis, only previous pregnancy (p = 0.033) and type of parametrectomy (p < 0.001) significantly influenced voiding recovery >7 days post-surgery. Type-B parametrectomy was associated with a higher risk of delayed voiding recovery than type-C1 (OR = 4.69; p = 0.023 vs. OR = 3.62; p = 0.052, respectively), followed by type-C2 (OR = 5.84; p = 0.011). Both previous pregnancy and type C2 parametrectomy independently prolonged time to voiding recovery by two days. CONCLUSIONS: Time to voiding recovery is significantly related to previous pregnancy and type of parametrectomy but it is not influenced by surgical approach (open vs minimally invasive), age, or BMI. Type B parametrectomy, without direct visualisation of nerves, was associated with longer recovery than nerve-sparing type C1. Importantly, voiding dysfunctions after radical surgery are temporary, and the majority of the patients recover in less than 30 days, including patients after C2 parametrectomy.

The quality of pathological assessment is crucial for the safety of patients with cervical cancer if pelvic lymph node dissection is to be replaced by sentinel lymph node (SLN) biopsy. Central pathology review of SLN pathological ultrastaging was conducted in the prospective SENTIX/European Network of Gynaecological Oncological Trial (ENGOT)-CX2 study. All specimens from at least two patients per site were submitted for the central review. For cases with major or critical deviations, the sites were requested to submit all samples from all additional patients for second-round assessment. From the group of 300 patients, samples from 83 cases from 37 sites were reviewed in the first round. Minor, major, critical, and no deviations were identified in 28%, 19%, 14%, and 39% of cases, respectively. Samples from 26 patients were submitted for the second-round review, with only two major deviations found. In conclusion, a high rate of major or critical deviations was identified in the first round of the central pathology review (28% of samples). This reflects a substantial heterogeneity in current practice, despite trial protocol requirements. The importance of the central review conducted prospectively at the early phase of the trial is demonstrated by a substantial improvement of SLN ultrastaging quality in the second-round review.
