Survival After Abdominal Q-M Type B versus C2 Radical Hysterectomy for Early-Stage Cervical Cancer.

PurposeTo evaluate the survival outcomes of abdominal Q-M type B and type C2 radical hysterectomy (RH) for early-stage (IA1 (lymphovascular invasion)-IIA2) cervical cancer.Patients and methodsBased on this multicenter, retrospective cohort study on the clinical diagnosis and treatment for cervical cancer in China (Four C), the survival outcomes of abdominal type B and type C2 RH for early-stage cervical cancer were compared under real-world and matched cohort study conditions.ResultsIn total, 46,313 cases were included in the Four C database, among whom 20,018 underwent abdominal type B or type C2 RH. In the real-world study, no differences were found in the 5-year overall survival (OS) between the type B group (n=15,471) and type C2 group (n=4547), but the 5-year disease-free survival (DFS) was lower in the type C2 group (82.1 vs 84.8%, hazard ratio: 1.144). Based on the inclusion criteria, 9135 cases were included and the type C2 group (n=1818) was found to have a lower 5-year OS and DFS (OS: 89.5 vs 92.0%, hazard ratio: 1.393; DFS: 84.3 vs 87.4%, hazard ratio: 1.342). Subsequently, 1799 cases from each group were matched and the type C2 group had a lower 5-year DFS (84.6 vs 88.4%, hazard ratio: 1.332). Upon further analysis of the subgroups, the type C2 group had a lower 5-year OS and DFS (OS: 90.3 vs 93.8%, hazard ratio: 1.522; DFS: 85.2 vs 89.4%, hazard ratio: 1.439).ConclusionQ-M type B RH could be used for the treatment of stage IA1 (lymphovascular invasion)-IIA2 cervical cancer.

Trend in proportion and clinicopathological characteristics of young women with stage Ⅰa2 to Ⅱa2 cervical cancer

Objective: To analyze the 13 years trend in proportion, risks factors and clinicopathological characteristics of young women with stage Ⅰa2 to Ⅱa2 cervical cancer by using multi-center data of cervical cancer in China. Methods: The clinicopathological data of 46 313 patients with cervical cancer treated from 37 hospitals in China were obtained from January 2004 to December 2016. Using clinical and pathologic data, each patient's stage was reclassified by the 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system. A total of 19 041 patients were selected according to the following criteria: FIGO stage Ⅰa2 to Ⅱa2, underwent type B or C radical hysterectomy and pelvic lymphadenectomy. All the patients were divided into two groups: the study group of 1 888 patients aged 35 years or younger and the control group of 17 153 patients aged over 35 years. The 13 years trend in proportion of young women with stage Ⅰa2 to Ⅱa2 cervical cancer, risks factors and clinicopathological characteristics of two groups were retrospectively analyzed. Results: (1) The total number of hospitalized patients with stage Ⅰa2 to Ⅱa2 cervical cancer increased annually. However, a downward trend of patients aged 35 years or younger was observed (P<0.01) . The constituent ratio of patients aged 35 years or younger was significantly greater during 2004-2010 than that during 2011-2016 [12.6% (820/6 484) and 8.5% (1 068/12 557) , respectively; χ(2)=82.101, P<0.01]. (2) Compared with patients aged over 35 years, patients aged 35 years or younger had an earlier age at menarche, a later age at marriage, lesser gravida and parity (all P<0.01). The positive rate of high-risk HPV infection was not statistically different between two groups (all P>0.05). (3) The proportions of stage Ⅰ, exophytic type and non-squamous histological type in patients aged 35 years or younger were clearly higher than those in patients aged over 35 years (83.4% vs 68.5%, P<0.01; 63.2% vs 56.2%, P<0.01; 13.9% vs 12.0%, P<0.05, respectively). Whereas the poor differentiation ratios of the two groups had no statistical significance (P>0.05). (4) As for the postoperative pathological risk factors, the rate of surgical margin involvement in patients aged 35 years or younger was lower than that aged over 35 years (1.1% vs 1.8%, P<0.05), and the rate of depth of stromal invasion >1/2 in patients aged 35 years or younger was lower than that in patients aged over 35 years (40.1% vs 50.9%, P<0.01). In addition, there were no significant difference in parametrial margin involvement, tumor size and lymph vascular space invasion between two groups (all P>0.05). Conclusions: The trend in proportion among hospitalized patients for stage Ⅰa2 to Ⅱa2 cervical cancer in young women is decreasing yearly. Compared with cervical cancer in middle-aged and elderly women, cervical cancer in young women have an earlier age at menarche, a higher proportion of stage Ⅰ patients and non-squamous histological type. In terms of the postoperative pathological risk factors, the rate of surgical margin involvement and depth of stromal invasion >1/2 in young women with cervical cancer are lower than in middle-aged and elderly women.

1870 Comparison of Laparoscopic Versus Open Radical Hysterectomy in Early Cervical Cancer after Completing Learning Curve and Reducing Intraperitoneal Tumor Exposure

Study Objective The main limitation of LACC trial is that the surgeon validation criteria for laparoscopic radical hysterectomy was not enough to include surgeons who completed learning curve for laparoscopic radical hysterectomy. So, the comparison between open and laparoscopic surgery was unfair. In addition, there was no safety measure to reduce intraperitoneal tumor exposure during laparoscopic radical hysterectomy. The aim of this study was to compare the survival outcomes between laparoscopic versus open radical hysterectomy in early cervical cancer after completing learning curve and reducing intraperitoneal tumor exposure. Design This was a retrospective study including patients with stage IA2 – IIA2 cervical cancer who underwent laparoscopic or open radical hysterectomy. All surgeons completed the learning curve for laparoscopic radical hysterectomy. To reduce the intraperitoneal tumor exposure during laparoscopic radical hysterectomy, all broken tumor tissues were washed out before colpotomy, and colpotomy and stump repair has been performed transvaginally. The survival outcomes were compared between laparoscopic and open radical hysterectomy. Setting University hospital. Patients or Participants 2,222 patients with early cervical cancer Interventions Laparoscopic and open radical hysterectomy. Measurements and Main Results During the study period, 854 and 1368 patients underwent open and laparoscopic radical hysterectomy, respectively. The 5-year DFS and OS did not differ between laparoscopic and open radical hysterectomy. The survival outcomes did not differ between laparoscopic and open radical hysterectomy both in patients with tumor 4 cm. The use of laparscopic surgery increased gradually and has become the main surgical approach during the study period. Each year's survival rate was not compromised despite the increased use of laparoscopic radical hysterectomy. Conclusion The survival outcome of laparoscopic radical hysterectomy is comparable to open radical hysterectomy after completing learning curve and reducing intraperitoneal tumor exposure during surgery.

Postoperative nomogram for the prediction of disease-free survival in lymph node-negative stage I–IIA cervical cancer patients treated with radical hysterectomy

The purpose of this study was to develop and validate a nomogram for individual prediction of recurrence and disease-free survival (DFS) among lymph node (LN)-negative early-stage (I–IIA) cervical cancer (CC) patients treated with Type B or Type C2 hysterectomy. Data were collected from patients diagnosed with CC between 1995 and 2017 at the Gynecological Oncology Department, Tepecik Training and Research Hospital. A total of 194 cases with stage IA2–IIA CC were evaluated retrospectively. Patients with stage IA2–IIA CC who underwent radical (Type C2) or modified radical (Type B) hysterectomy and pelvic ± paraaortic LN dissection with LN negativity were included in the study. The relationships between prognostic factors such as stage, tumour size, parametrial involvement, vaginal cuff margin, endomyometrial infiltration, and lymphovascular space invasion status and DFS were compared using a univariable Cox regression model. When the nomogram was prepared, the scores of the risk factors were collected, and we observed that scores were at least 0 to a maximum of 414 points. The concordance-index for the nomogram was 0.895 (95% confidence interval, 0.79–0.99). The nomogram based on the indicated prognostic factors yielded excellent results in predicting recurrence in early-stage CC patients without LN metastasis who underwent radical hysterectomy.Impact statementWhat is already known on this subject? Pathology of radical hysterectomy specimens in patients with early-stage cervical cancer provides information that has predictive prognostic potential. In addition to FIGO stage, other important prognostic factors are lymph node status, tumour size, parametrial involvement, vaginal cuff margin status, endomyometrial infiltration, histological type, patient age, lymphovascular space invasion, histological grade, and depth of cervical stromal invasion.What do the results of this study add? In this study, patients with early-stage cervical cancer who underwent radical and modified radical hysterectomy without retroperitoneal lymph node involvement were evaluated, and recurrence development and factors affecting disease-free survival were investigated. A nomogram consisting of factors influencing disease-free survival was constructed. The total score was determined according to the status of all risk factors. This allowed clear definition of the risk for each patient. A nomogram predicting recurrence in patients with stages IA2–IIA cervical cancer with radical hysterectomy without lymph node involvement has not previously been published.What are the implications of these findings for clinical practice and/or further research? Our study investigated early-stage cervical cancer (CC) patients without lymph node (LN) metastasis. Cox regression analysis was performed with six prognostic factors: FIGO stage, tumour size, parametrial margin infiltration, vaginal cuff margin involvement, endomyometrial infiltration, and LVSI positivity. The nomogram was constructed based on the results of Cox regression. The C-index for the nomogram was 0.895 (95% CI, 0.79–0.99). These results can be considered excellent. The higher concordance index in our study indicates that these six factors may be more valuable in predicting recurrence development in CC patients.

Radical CCRT Combined Thermotherapy for Ib2, IIa and Local Advanced Bulky Cervical Cancer: A Single Center Retrospective Study

To evaluate the safety and efficacy of thermotherapy combined radical radiotherapy concurrent chemotherapy for Ib2, IIa and local advanced cervical cancer. 30 patients diagnosed with cervical cancer from Jan 1, 2016 to Dec 31, 2017 were retrospectively studied. Among the patients, 1 pathologic diagnosed adenocarcinoma and 29 of squamous cell carcinoma; FIGO stage Ib2 10 patients and IIa-IVa 20 patients. All patients underwent radical chemotherapy concurrent radiotherapy (CCRT). Radiation composed of pelvic external beam radiation (EBRT) (50.4Gy/1.8Gy/28f 5f/w, EQD2=45Gy) and brachytherapy ( 6Gy/f 5f 2f/w, EQD2=40Gy) concurrent chemotherapy of DDP 40mg/m2 weekly, 6 weeks, total 55 days of treatment procedure. Hyperthermia (SR 1000 RF applicator, Xianke medical equipment co. LTD, Shenzhen ,China) were applied for these group of patients during the CCRT . Deep heating through the thermode to the tumor location 40.5～41°C 60 minutes twice a week, longer than 72hours interval. The temperature were read by the sensor which placed into the vagina. Objective response rate (ORR), time to progression (TTP) and side effects were analyzed. 30 patients median age 53 years old (39- 83y). Median follow up time was 16.5 months (9- 28ms). Mean maximum tumor diameter of primary cervical cancer was 4.37±0.28cm (2-8.3cm). ORR of end of EBRT before brachytherapy is 73% (CR+PR,22/30) and 4 patients CR; ORR of 1 months later after completion of CCRT is 96% (CR+PR,29/30) and 17 patients CR; ORR of 6 months later after completion of CCRT is 96% (CR+PR,29/30) and 20 patients CR. Mean local control time is 24.2±1.54 months (95% Confidence Interval 21.2ms-27.3ms), Median TTP was 15 months (3- 28ms), 1y and 2y local control rate was 83.3%. By the end of follow-up, 5 patients relapse in pelvic, 2 patients died because of distant metastasis. Early side effects of grade 1/2 myelosuppression was seen in 28 patients ( 93%), grade 4 myelosuppression was seen in 2 patients (7%). There were no grade 3/4 rectitis and grade 3/4 urethritis were observed. Thermotherapy Combined Radical CCRT for bulky Local Advanced Cervical Cancer is safe and effective and still need further investigation.

Value of diffusion-weighted and dynamic contrast-enhanced MR in predicting parametrial invasion in cervical stromal ring focally disrupted stage IB-IIA cervical cancers.

To compare the effectiveness of diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE) imaging in detecting parametrial invasion (PMI) in cervical stromal ring focally disrupted stage IB-IIA cervical cancers. Eighty-one patients with cervical stromal ring focally disrupted stage IB-IIA cervical cancers (PMI positive, n = 35; PMI negative, n = 46) who underwent preoperative MRI and radical hysterectomy were included in this study. Preoperative clinical variables and MRI variables were analyzed and compared. The Ktrans (min, mean, 10%, 25%, 50%, 75%, 90%), Kep (min, 10%, 25%, 50%, 75%, 90%), and Ve (min, 10%, 25%, 50%, 75%, 90%) values of patients with PMI were significantly higher than patients without PMI. The apparent diffusion coefficient (ADC) value did not show statistical difference between the two groups (1.01 ± 0.21 vs. 0.97 ± 0.20 10-3 mm2/s, p = 0.360). Tumor craniocaudal planes were higher in PMI-positive group than PMI-negative group (35.84 ± 15.39 vs. 29.70 ± 11.78mm, p = 0.048). Tumor craniocaudal planes combined with Kepmin value showed the highest area under the curve (AUCs) of 0.775, with a sensitivity of 72.7% and a specificity of 71.1% (p = 0.000). DCE parameters combined tumor craniocaudal planes may represent a prognostic indicator for PMI in cervical stromal ring focally disrupted IB-IIA cervical cancers.

Surgical resection based on ontogenetic cancer field theory for cervical cancer: mature results from a single-centre, prospective, observational, cohort study.

Previous findings from our centre suggest that carcinoma of the cervix propagates within ontogenetic cancer fields, tissue compartments defined by staged morphogenesis. We aimed to determine whether surgical treatment that accounts for stage-associated, ontogenetic cancer fields and their associated lymphoid tissues results in locoregional tumour control without the need for adjuvant radiotherapy. We did the final clinical and histopathological evaluation of data from, the single-centre, observational, cohort study, the Leipzig School Mesometrial Resection Study. Patients of any age with stage IB1, IB2, IIA1, IIA2, or IIB cervical cancer (according to 2009 International Federation of Gynecology and Obstetrics [FIGO]) had total mesometrial resection or extended mesometrial resection and therapeutic lymph node dissection, done on the basis of ontogenetic cancer fields. We defined sentinel node, first-line, second-line, and third-line lymph node regions as progressive regional cancer fields. Primary outcomes were disease-specific survival and recurrence-free survival, and treatment-related morbidity (assessed with the Franco-Italian glossary). Applying Cox proportional hazard models, ontogenetic local (T) and regional (N) tumour staging was compared with pathological T and N staging. This trial is registered with the German Clinical Trials Register, number DRKS00015171. Between Oct 16, 1999, and June 27, 2017, 523 patients were treated per protocol and followed up for a median of 61·8 months (IQR 49·3-94·8). In 495 patients with cervical cancer treated with cancer field surgery, 5-year disease-specific survival was 89·4% (95% CI 86·5-92·4) and recurrence-free survival was 83·1% (79·7-86·6). In the per-protocol population of 523 patients, treatment-related morbidity comprised 112 (21%) grade 2 and 15 (3%) grade 3 complications. The most common moderate and severe treatment-related complications and sequelae were wound dehiscence (17 [3%]), hydronephrosis (17 [3%]), bowel obstruction (26 [5%]), and lymph oedema (33 [6%]). One patient (<1%), who received total mesometrial resection, died from postoperative brain infarction. Total or extended mesometrial resection with therapeutic lymph node dissection based on ontogenetic cancer fields results in good survival outcomes of patients with cervical cancer in our institution, but needs to be investigated further in multicentre trials.

Risk Factors of Regional Lymph Node Metastasis in Patients with Cervical Cancer.

ObjectivesTo explore the risk factors related to regional lymph node metastasis in cervical cancer and analyze the value of independent risk factors in predicting regional lymph node metastasis.MethodsWe retrospectively analyzed the clinical data of 699 patients who underwent surgery for stage IB1–IIA2 cervical cancer in Quanzhou First Hospital affiliated to Fujian Medical University from 2010 to 2016. The patients were divided into metastasis (n = 92) and non-metastasis (n = 607) groups based on the postoperative pathology of regional lymph node status. The relevant clinicopathological features of the metastasis and non-metastasis groups were compared through variance analysis and chi-square tests. Logistic regression was adopted to screen relevant independent risk factors of regional lymph node metastasis.ResultsIn univariate analysis, International Federation of Gynecology and Obstetrics (FIGO) stages, serum squamous cell carcinoma antigen (SCC-Ag), histological type of squamous carcinoma and maximal tumor diameter were related factors for lymphatic metastasis in patients with cervical cancer. In multivariate analysis, SCC-Ag and histological type of squamous carcinoma were independent prognostic factors for lymphatic metastasis in patients with cervical cancer. Pre-treatment SCC-Ag serum levels, as a predictor of lymph node metastasis of cervical cancer, revealed a sensitivity of 62.07% (95% confidence interval (CI): 51.03–72.62%), specificity of 65.15% (59.07–70.89%), and area under the receiver operating characteristic (ROC) curve of 0.69 (95% CI: 0.61–0.76).ConclusionsCervical cancer patients whose pathological type is squamous carcinoma with high levels of SSC-Ag pre-operation are more likely to be diagnosed with regional lymph node metastasis. Standardized lymph node dissection should be implemented during operation.

Clinical Outcomes in Early Cervical Cancer Patients Treated with Nerve Plane–sparing Laparoscopic Radical Hysterectomy

To explore the feasibility of nerve plane-sparing laparoscopic radical hysterectomy (NPS-LRH) as a simplified C1-type surgery for cervical cancer patients and to compare this technique with laparoscopic radical hysterectomy (LRH). A retrospective comparative study. An academic tertiary hospital affiliated with the Chinese National Cancer Center. Six hundred fifteen patients with Fédération Internationale de Gynécologie et d'Obstétrique stage Ib and IIa cervical cancer who underwent laparoscopic radical hysterectomy between January 2010 and December 2017 were enrolled. Among them, 263 patients underwent the NPS-LRH surgery, and 352 patients underwent the LRH surgery. Intraoperative data and postoperative outcomes were compared between the 2 groups. NPS-LRH is a simplified type C1 procedure that preserves the ureteral mesentery and its nerve plane, whereas LRH is a type C2 procedure in the Querleu-Morrow surgical classification system. There were no statistically significant differences in age, body mass index, Fédération Internationale de Gynécologie et d'Obstétrique stage, tumor differentiation, pathological type, depth of invasion, lymphovascular space invasion, parametrial tissue invasion, lymphatic metastasis, neoadjuvant chemotherapy, or postoperative adjuvant radiotherapy and chemotherapy between the 2 groups. Compared with the LRH group, the NPS-LRH group had a shorter length of operation (238.7 ± 53.9 minutes vs 259.8 ± 56.6 minutes, p < .01), less intraoperative bleeding (p < .01), more resected lymph nodes (p = .028), shorter duration of urinary catheterization (p < .01), lower incidences of postoperative hydronephrosis (p = .044), less long-term frequent urination (p < .01), less acute urinary incontinence (p < .01), poor bladder sensation (p = .028), and constipation (p = .029). There were no statistically significant differences in the disease-free survival and overall survival between the 2 groups (p = .769 and .973, respectively). NPS-LRH is a simplified, safe, and feasible type C1 operation that had a shorter length of operation, less intraoperative bleeding, more resected lymph nodes, and better postoperative bladder function compared with the LRH group. Further studies are required to assess its benefits on rectal function and long-term prognosis.

Fluorescence sentinel lymph node mapping in patients with cervical cancer

Objective:to assess the efficacy of fluorescence sentinel lymph node (SLN) detection with indocyanine green (ICG) in patients with cervical cancer.Materials and methods.We analyzed the results of examination and treatment in 80 patients with morphologically verified stage IA1–IIA1 cervical cancer. All patients underwent laparoscopic surgery with fluorescence SLN detection with ICG using a high-resolution infrared camera.Results.SLNs were detected in 78 out of 80 patients (97.5 %); the rate of bilateral SLN detection was 80.0 % (64 out of 80). SLNs were not identified in 2 patients only (2.5 %). The majority of SLNs (99 out of 176; 56.28 %) were located in the internal group of lymph nodes, near to the common iliac artery bifurcation. Eleven out of 80 patients (13.75 %) were found to have pelvic lymph node metastasis. SLN metastatic lesions were observed in 10 out of 80 patients (12.5 %), whereas only one participant had non-SLN metastasis. Therefore, the sensitivity of the fluorescence method with ICG was 98.75 %.Conclusion.Fluorescence SLN mapping with ICG in patients with stage IA1–IIA1 cervical cancer is an effective diagnostic method allowing SLN topical diagnosis, intraoperative restaging, and correction of the treatment strategy.

Nerve-sparing radical hysterectomy compared to standard radical hysterectomy for women with early stage cervical cancer (stage Ia2 to IIa).

Radical hysterectomy is one of the standard treatments for stage Ia2 to IIa cervical cancer. Bladder dysfunction caused by disruption of the pelvic autonomic nerves is a common complication following standard radical hysterectomy and can affect quality of life significantly. Nerve-sparing radical hysterectomy is a modified radical hysterectomy, developed to permit resection of oncologically relevant tissues surrounding the cervical lesion, while preserving the pelvic autonomic nerves. To evaluate the benefits and harms of nerve-sparing radical hysterectomy in women with stage Ia2 to IIa cervical cancer. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 4), MEDLINE via Ovid (1946 to May week 2, 2018), and Embase via Ovid (1980 to 2018, week 21). We also checked registers of clinical trials, grey literature, reports of conferences, citation lists of included studies, and key textbooks for potentially relevant studies. We included randomised controlled trials (RCTs) evaluating the efficacy and safety of nerve-sparing radical hysterectomy compared to standard radical hysterectomy for women with early stage cervical cancer (stage Ia2 to IIa). We applied standard Cochrane methodology for data collection and analysis. Two review authors independently selected potentially relevant RCTs, extracted data, evaluated risk of bias of the included studies, compared results and resolved disagreements by discussion or consultation with a third review author, and assessed the certainty of evidence. We identified 1332 records as a result of the search (excluding duplicates). Of the 26 studies that potentially met the review criteria, we included four studies involving 205 women; most of the trials had unclear risks of bias. We identified one ongoing trial.The analysis of overall survival was not feasible, as there were no deaths reported among women allocated to standard radical hysterectomy. However, there were two deaths in among women allocated to the nerve-sparing technique. None of the included studies reported rates of intermittent self-catheterisation over one month following surgery. We could not analyse the relative effect of the two surgical techniques on quality of life due to inconsistent data reported. Nerve-sparing radical hysterectomy reduced postoperative bladder dysfunctions in terms of a shorter time to postvoid residual volume of urine ≤ 50 mL (mean difference (MD) -13.21 days; 95% confidence interval (CI) -24.02 to -2.41; 111 women; 2 studies; low-certainty evidence) and lower volume of postvoid residual urine measured one month following operation (MD -9.59 days; 95% CI -16.28 to -2.90; 58 women; 2 study; low-certainty evidence). There were no clear differences in terms of perioperative complications (RR 0.55; 95% CI 0.24 to 1.26; 180 women; 3 studies; low-certainty evidence) and disease-free survival (HR 0.63; 95% CI 0.00 to 106.95; 86 women; one study; very low-certainty evidence) between the comparison groups. Nerve-sparing radical hysterectomy may lessen the risk of postoperative bladder dysfunction compared to the standard technique, but the certainty of this evidence is low. The very low-certainty evidence for disease-free survival and lack of information for overall survival indicate that the oncological safety of nerve-sparing radical hysterectomy for women with early stage cervical cancer remains unclear. Further large, high-quality RCTs are required to determine, if clinically meaningful differences of survival exist between these two surgical treatments.

The Proportion of Lymph Node Metastasis in Patients with Stage IIA1 and IIA2 Cervical Cancer who were Treated for Radical Hysterectomy and Pelvic Lymphadenectomy

Comparison of survival outcomes between minimally invasive surgery and conventional open surgery for radical hysterectomy as primary treatment in patients with stage IB1–IIA2 cervical cancer

ObjectiveTo compare survival outcomes of minimally invasive surgery (MIS) and conventional open surgery for radical hysterectomy (RH) among patients with early-stage cervical cancer (CC). MethodsWe retrospectively identified stage IB1-IIA2 CC patients who underwent either laparoscopic or open Type C RH between 2000 and 2018. Patients' clinicopathologic characteristics and survival outcomes were compared according to the surgical approach. For a more robust statistical analysis, we narrowed the study population down to the patients with stage IB1 who underwent pre-operative MRI. ResultsIn total, 435 and 158 patients were assigned to open surgery and MIS groups, respectively. MIS group had significantly less parametrial invasion (6.3% vs. 15.4%; P = 0.004). Despite similar proportions of patients received adjuvant treatment, concurrent chemoradiation therapy was performed less frequently in MIS group. After a median follow up of 114.8 months, the groups showed similar overall survival; however, MIS group displayed poorer progression-free survival (PFS; 5-year rate, 78.5% vs. 89.7%; P < 0.001). Multivariate analyses identified MIS as an independent poor prognostic factor for PFS (adjusted HR, 2.883; 95% CI, 1.711–4.859; P < 0.001). Consistent results were observed among 349 patients with stage IB1: MIS was associated with higher recurrence rates (adjusted HR, 2.276; 95% CI, 1.039–4.986; P = 0.040). However, MIS did not influence PFS of stage IB1 patients with cervical mass size ≤2 cm on pre-operative MRI (adjusted HR, 1.146; 95% CI, 0.278–4.724; P = 0.850). ConclusionsOverall, MIS RH was associated with higher recurrence rates than open RH in patients with early-stage CC. However, MIS was not a poor prognostic factor among those with stage IB1 and cervical mass size ≤2 cm on pre-operative MRI.

Preoperative chemoradiation followed by hysterectomy for cervical cancer: patterns of care and survival in a large, hospital database.

ObjectiveAdjuvant hysterectomy following chemoradiation (CRT) is a treatment option used worldwide for early-stage cervical cancer but the benefit of hysterectomy in this setting is unclear. An analysis of the National Cancer Database (NCDB) was performed to identify patterns of care and determine the survival impact of adjuvant hysterectomy.MethodsThe NCDB was queried for patients with International Federation of Gynecology and Obstetrics stage IB2 to IIA2 cervical cancer diagnosed from 2010–2014 who underwent preoperative concurrent chemoradiation followed by hysterectomy (CRT+S) or definitive CRT. Overall survival (OS) curves were generated using the Kaplan-Meier method and compared via the log-rank test. Univariable and multivariable logistic regression and Cox regression were used to determine covariables associated with utilization and OS.ResultsThere were 1,546 patients who met the study criteria, of which 1,407 (91.0%) received concurrent CRT alone and 139 (9.0%) received CRT+S. Four-year OS for the CRT+S group was 82.2% and 74.9% for the CRT group (p=0.036). On subgroup analysis by lymph node status, the 4-year OS for patients without positive pelvic or para-aortic lymph nodes was 84.9% in the CRT+S group vs. 77.8% in the CRT group (p=0.072). On multivariable Cox regression, there was no difference in survival based on treatment group (hazard ratio=0.63; 95% confidence interval=0.06–1.04; p=0.069).ConclusionWe found from this hospital database that completion hysterectomy is used infrequently and did not result in a significant survival difference when accounting for other factors.

Tumor-infiltrating CD8+ and FOXP3+ lymphocytes before and after neoadjuvant chemotherapy in cervical cancer

BackgroundNeoadjuvant chemotherapy (NACT) has been recently accepted as an effective alternative in patients with locally advanced cervical cancer. However, little is known about the effects of NACT on the immunological microenvironment in cervical cancers. In this study, we analyzed the alterations of tumor infiltrating lymphocytes (TILs) before and after NACT and analyzed their prognostic significance in advanced cervical cancer patients treated with platinum-based NACT.MethodsWe recruited 137 patients with stage Ib2 and IIa2 cervical cancer retrospectively. Pretreatment biopsy and surgical specimens after NACT were immunostained with CD8 and Foxp3. The densities of intratumoral and peritumoral immunopositive TILs were analyzed separately.ResultsFoxp3+ T cells density significantly decreased in both intratumoral (median 28.49 vs. 19.97; Z = − 8.635, p < 0.001) and peritumoral (median 113.53 vs. 82.48; Z = − 3.741, p < 0.001) areas after NACT, whereas CD8+ T cell counts remained stable in both intratumoral (median 121.32 vs. 109.59; Z = − 0.817,p = 0.414) and peritumoral (median 402.56 vs. 390.84; Z = − 1.138,p = 0.255) areas. Patients with pathological complete response (pCR) had significantly lower number of Foxp3+ T cell density after NACT than non-pCR cases in both intratumoral (median16.12 vs. 22.00; Z = − 2.009, p = 0.045) and peritumoral areas(median 63.31 vs. 98.48; Z = − 2.469, p = 0.014). Multivariate analyses demonstrated that high ratio of intratumoral CD8/peritumoral Foxp3 in residual tumors was independent prognostic factor for both progression-free survival (HR = 0.297; 95% CI, 0.109–0.810, p = 0.018) and overall survival (HR = 0.078; 95% CI, 0.010–0.598, p = 0.014).ConclusionsNACT in cervical cancers can induce anti-cancer immunity by altering TILs subsets. An elevated intratumoral CD8/peritumoral Foxp3 ratio after NACT may confer a favorable clinical outcome.

Vaginal cuff length during radical hysterectomy is a prognostic factor for stage IB-IIA cervical cancer: a retrospective study.

PurposeThe aim of this study was to investigate the impact of vaginal cuff length (VCL) resected during radical hysterectomy (RH) on the long-term survival outcomes of patients with cervical cancer (International Federation of Gynecology and Obstetrics [FIGO] stage IB–IIA) and to explore whether VCL is a prognostic factor for cervical cancer.MethodsA total of 435 eligible patients with stage IB and IIA cervical cancer who underwent RH in Zhongnan Hospital of Wuhan University (Wuhan, People’s Republic of China) from January 2007 to February 2017 were retrospectively analyzed. These patients were divided into two groups (VCL ≤2.0 cm and >2.0 cm) for further analysis according to the VCL during RH. The Kaplan–Meier method was adopted to calculate the survival rates. Univariate and multivariate Cox regression models were used to analyze independent prognosis factors for survival.ResultsOf the 435 identified patients, 196 had VCL ≤2.0 cm and 239 had VCL >2.0 cm after RH. The 5-year disease-free survival (DFS) for the group who had VCL ≤2.0 cm vs the group who had VCL >2.0 cm was 68.1% vs 87.5% (P<0.001). Correspondingly, the overall survival (OS) for the two groups was 71.4% vs 89.2% (P<0.001). More interestingly, the VCL was significantly associated with the 5-year local recurrence rate, but not associated with the distant metastasis rate. In addition to the VCL, FIGO stage and lymph node involvement were also identified as significant prognostic factors for cervical cancer.ConclusionResection of VCL >2.0 cm in RH has a more favorable long-term outcome than VCL ≤2.0 cm among patients with cervical cancer (FIGO stage IB–IIA); shorter VCL resection was significantly associated with local recurrence, DFS, and OS; thus, it can be considered as a prognostic factor for cervical cancer.

Assessment of Parametrial Involvement in Early Stages Cervical Cancer With Preoperative Magnetic Resonance Imaging.

The objective of this study was to develop a predictive model for parametrial involvement (PMI) and to identify low-risk group of PMI in early stages of cervical cancer based on preoperative magnetic resonance imaging (MRI) parameters. We retrospectively analyzed patients with stages IB1 to IIA2 cervical cancer (N = 1347) who underwent type C radical hysterectomy between 2005 and 2012. Clinical records, preoperative MRI, and its association with pathological data were reviewed. A predictive model for PMI was developed using preoperative MRI parameters for the estimation of its performance. Of 1347 patients, 138 (10.2%) had pathological PMI (p-PMI). Multivariate analysis identified the maximal tumor diameter (odds ratio, 2.0; 95% confidence interval, 1.23-3.40; P < 0.001) and PMI (odds ratio, 7.0; 95% confidence interval, 4.49-11.02; P < 0.001) on preoperative MRI (m-PMI) as independent predictive factors for p-PMI. The rate of p-PMI was 1.3% for low-risk patients identified by the current model (maximal tumor diameter ≤2.5 cm and no indication of PMI, n = 448). The 5-year progression-free survival rate was significantly greater (96.7%) in low-risk patients than in those with a maximal tumor diameter greater than 2.5 cm and/or indication of m-PMI (90.8%, P = 0.004). A predictive model for p-PMI was developed in which p-PMI exclusion was set as a maximal tumor diameter less than or equal to 2.5 cm and no indication of m-PMI. Patients with a low risk of m-PMI could be identified so that less radical surgery for stages IB1 to IIA2 cervical cancer could be offered.
