Radical Hysterectomy After Neoadjuvant Chemotherapy for Locally Bulky-Size Cervical Cancer: A Retrospective Comparative Analysis between the Robotic and Abdominal Approaches

Radical hysterectomy (RH) is the standard treatment for early stage cervical cancer, but the surgical approach for locally bulky-size cervical cancer (LBS-CC) is still unclear. We retrospectively compared the outcomes of women with LBS-CC treated with neoadjuvant chemotherapy (NACT) and subsequent RH between the robotic (R-RH) and abdominal approaches (A-RH). Between 2012 and 2014, 39 women with LBS-CC FIGO (International Federation of Gynecology and Obstetrics) stage IB2-IIB were treated with NACT-R-RH (n = 18) or NACT-A-RH (n = 21). Surgical parameters and prognosis were compared. Patient characteristics were not significantly different between the groups, but the NACT-R-RH group had significantly more patients with FIGO stage IIB disease, received multi-agent-based NACT, and had a lower percentage of deep stromal invasion than the NACT-A-RH group. After NACT-R-RH, surgical parameters were better, but survival outcomes, such as disease-free survival (DFS) and overall survival (OS), were significantly worse. On multivariate analysis, FIGO stage IIB contributed to worse DFS (p = 0.003) and worse OS (p = 0.012) in the NACT-A-RH group. Women with LBS-CC treated with NACT-R-RH have better perioperative outcomes but poorer survival outcomes compared with those treated with NACT-A-RH. Thus, patients with FIGO stage IIB LBS-CC disease might not be suitable for surgery after multi-agent-based NACT.

[Place of radiotherapy and surgery in the treatment of cervical cancer patients]

The treatment of cervical cancer patients relies on surgery and radiotherapy (according to the stage) and requires a multimodal discussion before any treatment to avoid adding the morbidities of each individual intervention and to optimize functional and oncological outcomes. The places of surgery and radiotherapy have been highlighted in recent international guidelines. For early stage tumors, an exclusive surgery with or without fertility sparing (according to well defined criteria) is the therapeutic standard. For tumors with risk factors (measuring more than 2cm in size and/or presence of lymphovascular invasion) a preoperative brachytherapy can be proposed to minimize the need for postoperative external beam radiotherapy and optimize local control. For locally advanced disease, the standard treatment relies on chemoradiation followed by a brachytherapy boost. A primary paraaortic lymph node dissection may guide radiotherapy volumes and is useful to identify patients requiring a para-aortic radiotherapy. The technical evolutions of surgical approaches and technological improvement of radiotherapy and brachytherapy should be analyzed in the context of prospective studies. We review the literature on the respective places of radiotherapy and surgery for the treatment of cervical cancer.

Clinical management of early-stage cervical cancer: The role of sentinel lymph node biopsy in tumors ≤2 cm

OBJECTIVE

To evaluate the experience with sentinel lymph node (SLN) biopsy in patients with early-stage cervical cancer at our hospital, and to analyze factors influencing the rate of false negatives.

STUDY DESIGN

This study was carried out at the Vall d'Hebron Hospital (Barcelona, Spain) between September 2000 and October 2016. All patients underwent SLN biopsy and systematic and bilateral pelvic lymphadenectomy, followed by radical hysterectomy. SLNs were analyzed by the pathologist by staining with hematoxylin-eosin and immunohistochemistry.

RESULTS

Patients (N = 128) had been diagnosed with early-stage cervical cancer (FIGO-2009 stages 1A2, IB1, and IIA1). The combined SLN detection rate (99-technecium and a blue dye) was 98.4%, bilateral in 76% of the patients. Positive SLNs were found in 19 patients (14.8%). Sensitivity of detection was 79.2% (CI95, 57.9-92.9), false negative rate 20.8% (CI95, 7.1-42.2), and negative predictive value 95.4% (CI95, 89.6-98.5). False negative cases were observed in 5 patients with tumors >2 cm and presenting lymphovascular space invasion. Micrometastases were detected during SLN ultrastaging in 3 patients (2.3%). The median follow-up was 8.24 years and the 5-year overall survival (OS) was 88.4% (CI95, 80.9-93.1).

CONCLUSION

SLN mapping and biopsy in early-stage cervical cancer is feasible and has high sensitivity to detect patients with initial metastases. The risk of false negatives could be lower in certain groups of patients, such as those with tumors ≤2 cm and no lymphovascular space invasion, but future studies will be required to test this hypothesis.

Nerve-sparing radical hysterectomy: steps to standardize surgical technique

AIM

The primary objective of this review was to study and analyze techniques of nerve-sparing radical hysterectomy so as to be able to characterize and elucidate intricate steps for the dissection of each component of the pelvic autonomic nerve plexuses during nerve-sparing radical hysterectomy.

METHODS

This review was based on a five-step study design that included searching for relevant publications, selecting publications by applying inclusion and exclusion criteria, quality assessment of the identified studies, data extraction, and data synthesis.

RESULTS

There are numerous differences in the published literature concerning nerve-sparing radical hysterectomy including variations in techniques and surgical approaches. Techniques that claim to be nerve-sparing by staying above the dissection level of the hypogastric nerves do not highlight the pelvic splanchnic nerve, do not take into account the intra-operative patient position, nor the fact that the bladder branches leave the inferior hypogastric plexus in a ventrocranial direction, and the fact that inferior hypogastric plexus will be drawn cranially with the vaginal walls (if this is not recognized and isolated earlier) above the level of hypogastric nerves by drawing the uterus cranially during the operation.

CONCLUSIONS

The optimal nerve-sparing radical hysterectomy technique has to be radical (type C1) and must describe surgical steps to highlight all three components of the pelvic autonomic nervous system (hypogastric nerves, pelvic splanchnic nerves, and the bladder branches of the inferior hypogastric plexus). Recognizing the pelvic splanchnic nerves in the caudal parametrium and the isolation of the bladder branches of the inferior hypogastic plexus requires meticulous preparation of the caudal part of the ventral parametrium.

Radical Surgery in Advanced Cervical Cancer Patients Receiving Bevacizumab-Containing Chemotherapy: A "Real Life Experience"

BACKGROUND

Platinum-based chemotherapy plus bevacizumab is the new standard of care in stage IVB cervical cancer (CC) patients. In this new scenario, radical surgery could be offered in selected cases with an optimal clinical response. Potential surgical complications related to previous bevacizumab treatment have never been described before in this type of setting.

METHODS

This is a single-institutional retrospective study on women with CC who received radical pelvic surgery after platinum-based chemotherapy (platinum-taxol) plus bevacizumab.

RESULTS

Between April 2016 and September 2017, 15 patients with CC underwent radical surgery after bevacizumab-containing chemotherapy (platinum-taxol) at the Division of Gynecologic Oncology, Catholic University of the Sacred Heart in Rome, Italy.All patients received at least 3 cycles of treatment. Fourteen (93.4%) patients underwent radical hysterectomy, whereas 1 patient received pelvic anterior exenteration. Median operating time was 290 minutes (range, 220-400), and estimated blood loss was 250 mL (range, 50-1500). Median time of hospitalization was 5 days (range, 2-21). Pathological response in the cervix was complete in 3 cases and microscopic in 1 patient (26.7%). Intraoperative complications occurred in 3 cases: 2 vascular injuries and 1 ureteral injury. Three patients (20.0% of the whole series) experienced grade 3 complications.At last follow-up (median time, 9 months), the median overall survival is 13 months (range, 6-31): 7 (46.7%) women were free of disease, 8 (53.3%) patients progressed, and 3 of them died of disease.

CONCLUSIONS

Radical surgery can be performed in women with CC previously treated with a bevacizumab-containing regimen.

ESGO Survey on Current Practice in the Management of Cervical Cancer

OBJECTIVE

The aim of this survey was to acquire an overview of the current management of cervical cancer with an emphasis on the early disease stages.

MATERIALS AND METHODS

A hyperlink to the survey was sent to the European Society of Gynaecological Oncology Office database. The survey contained 6 groups of questions regarding the characteristics of respondents, pretreatment workup, management of the early stages of cervical cancer, adjuvant treatment, fertility-sparing treatment, and surveillance.

RESULTS

In total, 566 responses were collected. The most frequent imaging method used in the workup was magnetic resonance imaging (74%), followed by computed tomography (54%) and positron emission tomography/computed tomography (25%). Conization or simple hysterectomy was a preferred procedure in stage T1a1 lymphovascular space invasion (LVSI)-positive for 79% of respondents, in stage T1a2 LVSI-negative for 58%, and in stage T1a2 LVSI-positive for 28%. Sentinel lymph node biopsy alone was reported in stage T1a1 by 17% and in stage T1b1 less than 2 cm by 9%, whereas systematic lymphadenectomy by 29% and 90% of respondents. Macrometastases, micrometastases, and isolated tumor cells in lymph nodes were considered indications for adjuvant treatment by 96%, 93%, and 68% of respondents, respectively. Neoadjuvant chemotherapy was reported by 28% and 19% of respondents in fertility-sparing and nonsparing management in stage T1b1. Over 60% of respondents recommend primary surgery for their patients with T1b2 N0 disease and 81% of them use a combination of adverse prognostic factors as indication for adjuvant radiotherapy in pN0 disease.

CONCLUSIONS

The results of this survey indicate considerable differences in the workup and treatment of cervical cancer in current clinical practice.

Analysis of isolated loco-regional recurrence rate in intermediate risk early cervical cancer after a type C2 radical hysterectomy without adjuvant radiotherapy

BACKGROUND

The efficacy of adjuvant radiotherapy in patients with intermediate risk early cervical cancer after radical hysterectomy is still under debate. Most guidelines recommend adjuvant radiotherapy, whereas others consider observation a viable option.

OBJECTIVE

To investigate if patients with intermediate risk factors for cervical cancer who underwent radical hysterectomy may benefit from adjuvant radiotherapy.

METHODS

Consecutive patients with tumor confined to the cervix and intermediate risk factors (according to Sedlis), treated between January 1982 and December 2014 who were observed after a type C2 radical hysterectomy formed the basis for this study. The frequency of recurrences, specifically isolated loco-regional recurrences, and the risk of death from recurrences, were analyzed. Data were analyzed using SPSS, version 23.0 for Windows RESULTS: A total of 161 patients were included in the analysis. Median age was 40 (range 20-76). Stages IB1 and IB2 were seen in 87 (54%) and 74 patients (46%), respectively. Squamous cell and non-squamous histology was seen in 114 (70.8%) and 47 patients (29.2%), respectively. Of the 161 patients, 25 (15.5%) had recurrent disease, of whom nine had an isolated loco-regional recurrence (5.6%). Median time to recurrence for isolated loco-regional recurrences was 28 months (range 9-151). Treatment for an isolated loco-regional recurrence was radiotherapy (n = 4) and chemoradiotherapy (n = 5). Four patients (2.5%) died from disease as a result of an isolated loco-regional recurrence. Actuarial disease- specific survival was 93.0% for the total group. No variables were found that predicted an isolated loco-regional recurrence.

DISCUSSION

The mortality from isolated loco-regional recurrence in patients with intermediate risk factors for cervical cancer who underwent only radical hysterectomy type C2 was 2.5%. Further studies should compare outcomes between patients who undergo a type C2 radical hysterectomy without adjuvant radiotherapy with those undergoing a less radical hysterectomy but with adjuvant radiotherapy.

Standardization of laparoscopic extrafascial hysterectomy: anatomic considerations to protect the ureter

PURPOSE

To describe the procedure of laparoscopic extrafascial hysterectomy to avoid ureter injury.

METHODS

Data were obtained from: (1) anatomic study of ten fresh female cadavers to measure the distance between the point where the ureter and uterine artery cross and the level of section of the ascending branch of the uterine artery during extrafascial dissection of the uterine pedicle and uterosacral ligament (Paris School of Surgery). The Wilcoxon test was used to compare measurements within each subject. P < 0.05 was considered to denote significance; (2) prospectively collected clinical data from women undergoing laparoscopic extrafascial hysterectomy from July 2006 to March 2014 at Poissy University Hospital, to describe the laparoscopic extrafascial hysterectomy technique with analysis of surgical complications using the Clavien-Dindo classification.

RESULTS

Anatomic study: The mean (SD) distance between the point where the ureter and uterine artery cross and the level of the section of the ascending branch of the uterine artery were: 11.6 mm (5.2) in neutral position and 25 mm (7.5) after pulling the uterus laterally; and 25mm (8.9) after sectioning the ascending portion of the uterine pedicle and 38.6 mm (4.5) after complete uterine artery pedicle dissection through the uterosacral ligaments. After release of the ureter, the curve in front of the uterine artery disappeared. Clinical laparoscopic study: Sixty-eight patients underwent laparoscopic extrafascial hysterectomy. No ureteral complications occurred.

CONCLUSION

Laparoscopic extrafascial hysterectomy is a safe and feasible procedure. Combined lateralization and elevation of the uterus, section of the ascending branch of the uterine artery, and its extrafascial dissection along the uterosacral ligament contribute to protecting the ureter during the procedure.

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

STUDY OBJECTIVE

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).

DESIGN

A retrospective comparative study.

SETTING

An academic tertiary hospital affiliated with the Chinese National Cancer Center.

PATIENTS

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.

INTERVENTIONS

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.

MEASUREMENTS AND MAIN RESULTS

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).

CONCLUSION

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.

Prognostic Value of Preoperative Systemic Immune-Inflammation Index in Patients with Cervical Cancer

The systemic immune-inflammation index (SII) based on peripheral lymphocyte, neutrophil and platelet counts has been considered a good index that reflects the local immune response and systemic inflammation. However, the use of the SII has not been reported in cervical cancer. In this study, Kaplan-Meier survival analysis showed that a high SII was associated with poor prognosis in cervical cancer patients in the primary and validation cohorts. A higher SII had a significant correlation with larger tumours but had no correlation with other clinicopathological parameters. Among all systemic immune indexes, the SII is the only independent prognostic factor for cervical cancer patients. Compared with the area under the curve for the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and monocyte/lymphocyte ratio (MLR), the area for the SII was larger at 3 and 5 years. In addition, the SII still retains it prognostic values across all FIGO stages. The SII can independently predict the overall survival of patients with cervical cancer receiving radical resection and is thus superior to existing systemic inflammatory indexes. The prognostic nomogram based on the SII is a reliable model for predicting the postoperative survival of patients with cervical cancer.

A prospective multicenter trial on sentinel lymph node biopsy in patients with early-stage cervical cancer (SENTIX)

Objective

Sentinel lymph node (SLN) biopsy has been increasingly used in the management of early-stage cervical cancer. It appears in guidelines as an alternative option to systematic pelvic lymphadenectomy. The evidence about safety is, however, based mostly on retrospective studies, in which SLN was combined with systematic lymphadenectomy.

Materials and methods

SENTIX is a prospective multicenter trial aiming to prove that less-radical surgery with SLN is non-inferior to treatment with systematic pelvic lymphadenectomy. The primary end point is recurrence rate; the secondary end point is the prevalence of lower-leg lymphedema and symptomatic pelvic lymphocele. The reference recurrence rate was set up conservatively at 7% at 24 months after treatment. With a sample size of 300 patients treated per protocol, the trial is powered to detect a non-inferiority margin of 5% (90% power, p = 0.05) for recurrence rate, 30% reduction in the prevalence of symptomatic lymphocele or lower-leg lymphedema, with reference rates of 30% and 6% at 12 months (p = 0.025, Bonferroni correction). The patients eligible for SENTIX have stage IA1/LVSI+, IA2, IB1 (<2 cm for fertility sparing), with negative LN on pre-operative imaging. Intra-operatively, patients are excluded when there is a failure to detect SLN on both sides of the pelvis in cases of more advanced cancer (stage >IB1), or a positive intra-operative SLN assessment. The quality of SLN pathology evaluation will be assessed by central review. Three interim safety analyses are pre-planned when 30, 60, 150 patients complete 12 months' follow-up.

Conclusions

The first patient was enrolled into the study in June 2016 and, by June 2018, 340 patients had been enrolled. The first analysis of secondary outcomes should be available in 2019 and the oncological outcome of 300 patients at the end of 2021. The trial is registered as a CEEGOG trial (CEEGOG CX-01), ENGOT trial (ENGOT-Cx 2), and at the ClinicalTrials.gov database (NCT02494063).

Tailoring radicality in early cervical cancer: how far can we go?

Today, the patient who is diagnosed with early cervical cancer is offered a variety of treatments apart from standard therapy. Patients can be treated with a less radical hysterectomy (RH) regarding parametrectomy, a trachelectomy either vaginal or abdominal, and this can be performed through a minimal invasive or open procedure. All this in combination with nerve sparing and/or sentinel node technique. Level 1 evidence for the oncological safety of all these modifications is only available from 3 randomized controlled trials (RCTs). Two RCTs on more or less radical parametrectomy both showed that oncological safety was not compromised by doing less radical surgery. Because of the heterogeneity of the patient population and the high frequency of adjuvant radiotherapy, the true impact of surgical radicality cannot be assessed. Regarding the issue of oncological safety of fertility sparing treatments, case-control and retrospective case series suggest that trachelectomy is safe as long as the tumor diameter does not exceed 2 cm. Recently, both a RCT and 2 case-control studies showed a survival benefit for open surgery compared to minimally invasive surgery, whereas many previous case-control and retrospective case series on this subject did not show impaired oncological safety. In a case-control study the survival benefit for open surgery was restricted to the group of patients with a tumor diameter more than 2 cm. Although modifications of the traditional open RH seem safe for tumors with a diameter less than 2 cm, ongoing prospective RCTs and observational studies should give the final answer.

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

Purpose

The 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.

Methods

A 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.

Results

Of 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.

Conclusion

Resection 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.

Perineural invasion as a prognostic risk factor in patients with early cervical cancer

The aim of the present study was to investigate the influence of perineural invasion (PNI) on the prognosis of patients with early cervical cancer (stages IA2-IIA2). A retrospective analysis was conducted on 406 patients with early cervical cancer who underwent a radical hysterectomy and pelvic lymphadenectomy between January 2007 and December 2014 at the Affiliated Hospital of Jiangnan University (Wuxi, China). The clinicopathological data of the patients were obtained and follow-up assessments were performed. A statistical analysis of the association between PNI and each index was performed, and the effect of PNI and the clinicopathological parameters on the prognosis of the patients was evaluated. Among the 406 cases with early cervical cancer, 41 cases were lost, with a follow-up rate of 89.90%. Overall, 43 PNI-positive patients were observed, with an occurrence rate of 10.59%. PNI-positivity was associated with hypertension, lymph node metastasis, depth of cervical invasion, surgical margin and vascular invasion (P<0.05), but it was not associated with age, diabetes, clinical stage, histological type or tumor size (P>0.05). The overall survival (OS) and disease-free survival (DFS) times of PNI-positive patients were significantly lower compared with those of PNI-negative patients. A multivariate regression analysis revealed that age, tumor size, clinical stage and PNI were independent risk factors for OS and DFS times. PNI is a poor prognostic factor for patients with early cervical cancer.

Laparoscopic Nerve-Sparing Radical Hysterectomy vs Laparoscopic Radical Hysterectomy in Cervical Cancer: A Systematic Review and Meta-Analysis of Clinical Efficacy and Bladder Dysfunction

It is widely accepted that nerve-sparing radical hysterectomy is associated with less postoperative morbidity compared with radical hysterectomy, whereas clinical safety is similar in the 2 procedures. However, there is insufficient evidence to compare these procedures performed via a laparoscopic approach. We performed a systematic review and meta-analysis of studies to compare the clinical efficacy and the rate of bladder dysfunction, including urodynamic assessment, in laparoscopic nerve-sparing radical hysterectomy (LNSRH) and laparoscopic radical hysterectomy (LRH). Thirty articles including a total of 2743 participants were analyzed. Operating times were shorter (MD, 29.88 minutes; 95% confidence interval [CI], 11.92-47.83 minutes) and hospital stays were longer (MD, -1.56 days; 95% CI, -2.27 to -0.84 days) in the LRH group compared with the LNSRH group. In addition, blood loss and the number of resected lymph nodes were not significantly different between the 2 groups. However, resected parametrium length (MD, -0.02 cm; 95% CI, -0.05 to -0.00 cm) and vaginal cuff width (MD, -0.06 cm; 95% CI, -0.09 to -0.04) were smaller in the LNSRH group. Furthermore, LNSRH tended to result in more satisfactory micturition (odds ratio, 2.90; 95% CI, 2.01-4.19), shorter catheterization time (MD, -7.20 days; 95% CI, -8.10 to -6.29 days), and shorter recovery to normal postvoid residual urine time (MD, -7.71 days; 95% CI, -8.92 to -6.50 days). Other bladder dysfunction symptoms, including urinary retention, nocturia, dysuria, urinary incontinence, and frequency/urgency were more frequent in the LRH group. Furthermore, LNSRH achieved better results in urodynamic assessments (all p < .05). In conclusion, LNSRH was associated with lower rates of impaired bladder function and a shorter extent of resection compared with LRH. Clinical applications involving LNSRH should be explored with caution.

Surgical treatment of "intermediate risk" lymph node negative cervical cancer patients without adjuvant radiotherapy-A retrospective cohort study and review of the literature

OBJECTIVES

The role of adjuvant radiotherapy for lymph node-negative stage IB patients with tumor-related negative prognostic factors is not uniformly accepted. It is advocated based on the GOG 92 trial, which was initiated in 1989. The aim of the current study is to report the oncological outcome of "intermediate risk" patients treated by tailored surgery without adjuvant radiotherapy. Data from two institutions that refer these patients for adjuvant radiotherapy served as a control group.

METHODS

Included were patients with stage IB cervical cancer treated with radical hysterectomy and pelvic lymphadenectomy, who had negative pelvic lymph nodes but a combination of negative prognostic factors adopted from the GOG 92 trial. Data were obtained from prospectively collected databases of three institutions. Radical surgery was a single-treatment modality in one of them and in the remaining two institutes it was followed by adjuvant chemoradiation.

RESULTS

In 127 patients who received only radical surgery, with a median follow-up of 6.1 years, the local recurrence rate was 1.6% (2 cases), and total recurrence was 6.3% (8 cases). Disease-specific survival at 5 years was 95.7% (91.9%; 99.4%) and 91% (83.7%; 98.3%) at 10 years. The only significant factor for disease-specific survival was tumor size ≥4 cm (P = 0.032). The recurrence rate, local control or overall survival did not differ from the control group. Adjuvant radiotherapy was not a significant prognostic factor within the whole cohort.

CONCLUSIONS

An excellent oncological outcome, especially local control, can be achieved by both radical surgery or combined treatment in stage IB lymph node-negative cervical cancer patients with negative prognostic factors. The substantially better outcome than in the GOG 92 trial can be attributed to more accurate pre-operative and pathological staging and an improvement in surgical techniques.

Predictive factors of severe perioperative morbidity of radical hysterectomy with lymphadenectomy in early-stage cervical cancer: A French prospective multicentric cohort of 248 patients

OBJECTIVE

The purpose of this study was to assess the postoperative morbidity after radical hysterectomy (RH) for early-stage cervical cancer and to determine risk factors of severe perioperative morbidity.

METHODS

Data of two prospective trials on sentinel node biopsy for cervical cancer (SENTICOL I & II) were analysed. Patients having a radical hysterectomy were included between 2005 and 2012 from 25 French oncologic centers. Postoperative complications were prospectively recorded in a pre-specified analysis.

RESULTS

248 patients met the inclusion criteria. The median age was 44.5 years [25-85]. 88.7% of patients had a stage IB1 disease. There were 71.4% epidermoid carcinomas and 25% adenocarcinomas. 125 patients (50.4%) had a laparoscopic-assisted vaginal RH, 88 patients (35.5%) had a total laparoscopic RH, 26 patients (10.5%) had an open RH and 9 patients (3.6%) had a robotic-assisted RH. Sixteen patients (6.4%) had intraoperative complications. On a multivariate analysis, intraoperative complications were significantly associated with BMI >30 kg/m². The urinary, lymphovascular and neurologic complications rates were respectively 34.3%, 20.6% and 19.8%. 31 patients (12.5%) had severe postoperative complications (Clavien-Dindo ≥ 3 or CTCAE ≥ 3). On multivariate analysis, severe postoperative complications were associated with parametrial involvement, preoperative brachytherapy and inclusion in low surgical skills center.

CONCLUSIONS

This study based on prospective data showed that RH has low severe postoperative complications. The main complications were urinary infections and lower limb lymphedema. Patients with early-stage cervical cancer should be referred to expert center to ensure best surgical outcomes.

Voiding Dysfunction After Non-urologic Pelvic Surgery

PURPOSE OF REVIEW

Urinary dysfunction is a common entity in patients undergoing radical pelvic surgery for non-urologic malignancies. These dysfunctions may manifest as lower urinary tract symptoms (LUTS) or signs such as urinary retention or leakage. Review of current literature is performed to describe the differing urinary dysfunctions that manifest after colorectal resection, hysterectomy, and sacrectomy.

RECENT FINDINGS

Conventional radical surgery for pelvic malignancies often will result in debilitating functional problems. As advances in surgical techniques and management options become more available, patients can have better functional outcomes, specifically in the lower urinary tract. Nerve-sparing techniques as well as vascular preservation are becoming more important to preserve function as patient survival is improving. Additionally, newer methods are being explored, such as nerve stimulation for those who are unable to empty adequately. This article also addresses different management options for specific voiding dysfunction that may result from pelvic surgery. Preventative strategies such as nerve preservation during surgery are an important concept to prevent urinary dysfunction. The goal to good functional outcomes includes maintaining reservoir compliance and capacity as well as allowing proper outlet for voiding. We discuss different modalities to help achieve a functional lower urinary tract for patients with lower urinary tract dysfunction after pelvic surgery.

Locally advanced cervical cancer complicating pregnancy: A case of competing risks from the Catholic University of the Sacred Heart in Rome

A case of stage IB2 cervical cancer at 27 weeks of pregnancy, treated with neoadjuvant chemotherapy followed by radical Cesarean hysterectomy with full pelvic and infra-mesenteric lymphadenectomy, and adjuvant chemo-radiation is described. While she remains without disease, her baby was diagnosed with acute myelogenous leukemia. We highlight the pre-operative work-up, treatment options, safety, feasibility, and outcomes for the mother and her fetus.

Radical Hysterectomy: Efficacy and Safety in the Dawn of Minimally Invasive Techniques

STUDY OBJECTIVE

To analyze the effect that the introduction of minimally invasive procedures has had on surgical and oncologic outcomes when compared with conventional open radical hysterectomy (ORH) in a national reference cancer after 17 years of experience in radical hysterectomy.

DESIGN

A prospective controlled study (Canadian Task Force classification II-2).

SETTING

A university teaching hospital.

PATIENTS

All patients who underwent radical hysterectomy as primary treatment for cervical cancer in our institution between May 1999 and June 2016, with a total of 188 patients.

INTERVENTIONS

Patients underwent ORH or minimally invasive surgery (MIS) (i.e., laparoscopic or robotically assisted radical hysterectomy).

MEASUREMENTS AND MAIN RESULTS

Seventy-six patients underwent ORH, 90 laparoscopic radical hysterectomy, and 22 robotically assisted radical hysterectomy. Blood loss and hospital stay were inferior in the MIS group (p <.0001). The laparotomic group presented shorter operation times (p = .0001). With a median follow-up of 112.4 months, a total of 156 patients (83%) were alive and free of disease at the time of the data analysis. Overall survival was higher in the MIS group when compared with the ORH group (91 vs 78.9, p = .026). There were no differences regarding recurrence rates between the surgical approaches.

CONCLUSION

With 1 of the largest follow-up periods in the literature, this study provides added evidence that MIS could become the preferable surgical approach for early-stage cervical cancer since it appears to reduce morbidity without affecting oncologic results.

Predicting factors for resumption of spontaneous voiding following nerve-sparing radical hysterectomy

Objective

To determine factors affecting voiding recovery on the day of Foley catheter removal (postoperative day 7, POD7) after nerve-sparing radical hysterectomy (NSRH) for early-stage cervical cancer.

Methods

Early-stage cervical cancer patients, who underwent type C1 radical hysterectomy between January 2006 and June 2016 were included. Clinical and pathological data were reviewed. Association between inability to attain adequate voiding function on POD7 and potential predicting factors were evaluated in univariate and multivariate analysis.

Results

Of 755 patients, 383 (50.7%) resumed adequate voiding function on POD7 while 372 (49.3%) did not. Tumor size was larger in patients whose voiding function was inadequate (2.5 vs. 2.0 cm, p=0.001). Lengths of resected parametria and adjacent vagina were more extensive in patients with inadequate voiding function (p<0.001). In univariate analysis, factors significantly associated with inability to attain adequate voiding function included tumor size >4 cm (p<0.001), primary surgeon (p<0.001), postoperative urinary tract infection (p<0.01), grossly visible tumor (p<0.01), and not having prior conization (p<0.01). In multivariate analysis, tumor size >4 cm, postoperative urinary tract infection, and primary surgeon were significantly associated with inability to attain adequate voiding function on POD7.

Conclusion

Extent of disease represented by tumor size, urinary tract infection as well as individual surgeon's technique independently predict resumption of adequate voiding function on POD7 following NSRH.

Limited energy parametrial resection/dissection during modified laparoscopic nerve-sparing radical hysterectomy

Objective

The aim of this study was to investigate the feasibility of using ultrasonic scalpel combined with vascular clip in parametrial management, called limited energy parametrial resection/dissection (LEPRD), in laparoscopic nerve plane-sparing radical hysterectomy (NPSRH), a modified nerve-sparing radical hysterectomy (NSRH); and to evaluate its effectiveness in pelvic autonomic nerve preservation.

Methods

From July 2012 to January 2016, 257 consecutive patients with stage IB1 to IIA2 cervical cancer who underwent NPSRH were included in this study. Patients were divided into three cohorts according to the different parametrial resection modality. The clinical, pathological and surgery-related parameters were compared between the three groups. Short- and long-term postoperative bladder functions were evaluated.

Results

LEPRD was attempted in 94 patients, and was successful in 65 (69.1%) patients (LEPRD group). The remaining 29 (30.9%) patients required bipolar coagulation after failure of vascular clipping (combined modality group). Routine bipolar cautery was used in the other 163 patients during the parametrial resection (bipolar group). The blood loss in the LEPRD group was significantly lower than those in the other two groups (P<0.001). The rate of successful Foley removal on postoperative day 7 was significantly higher in the LEPRD group than in the bipolar group (P=0.022). The incidence of chronic voiding dysfunction was significantly lower in the LEPRD group than in the bipolar group (P=0.019).

Conclusions

It is feasible to perform LEPRD in NPSRH for cervical cancers. This kind of limited energy surgical technique is associated with less blood loss, and leads to improved postoperative bladder function.

[Primary management of endometrial carcinoma. Joint recommendations of the French society of gynecologic oncology (SFOG) and of the French college of obstetricians and gynecologists (CNGOF)]

OBJECTIVES

The management of endometrial carcinoma is constantly evolving. The SFOG and the CNGOF decided to jointly update the previous French recommendations (Institut national du cancer 2011) and to adapt to the French practice the 2015 recommendations elaborated at the time of joint European consensus conference with the participation of the three concerned European societies (ESGO, ESTRO, ESMO).

MATERIAL AND METHODS

A strict methodology was used. A steering committee was put together. A systematic review of the literature since 2011 has been carried out. A first draft of the recommendations has been elaborated, with emphasis on high level of evidence. An external review by users representing all the concerned discipines and all kinds of practice was completed. Three hundred and four comments were sent by 54 reviewers.

RESULTS

The management of endometrial carcinoma requires a precise preoperative workup. A provisional estimate of the final stage is provided. This estimation impact the level of surgical staging. Surgery should use a minimal invasive approach. The final pathology is the key of the decision concerning adjuvant therapy, which involves surveillance, radiation therapy, brachytherapy, or chemotherapy.

CONCLUSION

The management algorithms allow a fast, state of the art based, answer to the clinical questions raised by the management of endometrial cancer. They must be used only in the setting of a multidisciplinary team at all stages of the management.
