Minimally Invasive versus Abdominal Radical Hysterectomy for Cervical Cancer

Post Treatment Sexual Function and Quality of Life of Patients Affected by Cervical Cancer: A Systematic Review

Introduction: The aim of this study is to analyze the available scientific evidence regarding the quality of life (QoL) and sexual function (SF) in patients affected by cervical cancer (CC) after surgical and adjuvant treatments. Materials and Methods: Preliminary research was conducted via electronic database (MEDLINE, PubMed and Cochrane Library) with the use of a combination of the following keywords: SF, QoL, and CC. The principal findings considered in the present review were the study design, the number of patients included in each study, the information about the malignancy (histology and stage of disease), the questionnaires administered, and the principal findings concerning SF and QoL. Results: All studies were published between 2003–2022. The studies selected consisted of one randomized control study, seven observational studies (three prospective series), and nine case control studies. The scores used were focused on SF, QOL, fatigue, and psychological aspects. All studies reported a decreased SF and QOL. The most developed questionnaires were the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the Female Sexual Function Index (FSFI), the Hospital Anxiety and Depression scale (HADS), and the Female Sexual Distress Scale (FSDS). Discussion: All studies reported a decreased SF and QOL. In addition to the perception of body image, several factors coexist in influencing the outcomes such as the physical, hormonal, psychological. Conclusions: Sexual dysfunction after CC treatment has a multifactorial aetiology which negatively affects the quality of life. For these reasons, it is important to follow and support patients with a multidisciplinary team (doctors, nurses, psychologists, dieticians) before and after therapy. This type of tailored therapeutic approach should become a standard. Women should be informed about possible vaginal changes and menopausal symptoms after surgery and on the positive effects of psychological therapy.

Effect of minimally invasive surgery and laparotomy on wound infection and postoperative and intraoperative complications in the management of cervical cancer: A meta-analysis

We performed a meta-analysis to evaluate the effect of minimally invasive surgery and laparotomy on wound infection and postoperative and intraoperative complications in the management of cervical cancer. A systematic literature search up to July 2022 was performed and 10 231 subjects with cervical cancer at the baseline of the studies; 4307 of them were using the minimally invasive surgery, and 5924 were using laparotomy. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated to assess the effect of minimally invasive surgery and laparotomy on wound infection and postoperative and intraoperative complications in the management of cervical cancer using the dichotomous methods with a random or fixed-effect model. The minimally invasive surgery had significantly lower wound infection (OR, 0.20; 95% CI, 0.13-0.30, P < .001), and postoperative complications (OR, 0.48; 95% CI, 0.37-0.64, P < .001) in subjects with cervical cancer compared laparotomy. However, minimally invasive surgery compared with laparotomy in subjects with cervical cancer had no significant difference in intraoperative complications (OR, 1.04; 95% CI, 0.80-1.36, P = 0.76). The minimally invasive surgery had significantly lower wound infection, and postoperative complications however, had no significant difference in intraoperative complications in subjects with cervical cancer compared with laparotomy. The analysis of outcomes should be with caution because of the low sample size of 22 out of 41 studies in the meta-analysis and a low number of studies in certain comparisons.

Perioperative and Oncological Outcomes of Robotic Versus Open Pancreaticoduodenectomy in Low-Risk Surgical Candidates: A Multicenter Propensity Score-Matched Study

OBJECTIVES

This study aimed to perform a multicenter comparison between robotic pancreaticoduodenectomy (RPD) and open pancreaticoduodenectomy (OPD).

BACKGROUND

Previous comparisons of RPD versus OPD have only been carried out in small, single-center studies of variable quality.

METHODS

Consecutive patients who underwent RPD (n = 1032) or OPD (n = 1154) at 7 centers in China between July 2012 and July 2020 were included. A 1:1 propensity score matching (PSM) was performed.

RESULTS

After PSM, 982 patients in each group were enrolled. The RPD group had significantly lower estimated blood loss (EBL) (190.0 vs 260.0 mL; P < 0.001), and a shorter postoperative 1length of hospital stay (LOS) (12.0 (9.0-16.0) days vs 14.5 (11.0-19.0) days; P < 0.001) than the OPD group. There were no significant differences in operative time, major morbidity including clinically relevant postoperative pancreatic fistula (CR-POPF), bile leakage, delayed gastric emptying, postoperative pancreatectomy hemorrhage (PPH), reoperation, readmission or 90-day mortality rates. Multivariable analysis showed R0 resection, CR-POPF, PPH and reoperation to be independent risk factors for 90-day mortality. Subgroup analysis on patients with pancreatic ductal adenocarcinoma (PDAC) (n = 326 in each subgroup) showed RPD had advantages over OPD in EBL and postoperative LOS. There were no significant differences in median disease-free survival (15.2 vs 14.3 months, P = 0.94) or median overall survival (24.2 vs 24.1 months, P = 0.88) between the 2 subgroups.

CONCLUSIONS

RPD was comparable to OPD in feasibility and safety. For patients with PDAC, RPD resulted in similar oncologic and survival outcomes as OPD.

Cutting-edge Treatment for Gynecological Malignancies

Gynecological malignant tumors can develop in the vulva, vagina, uterus, fallopian tubes, or ovaries in the female reproductive tract. The cervix, uterine body, and ovaries are particularly common sites for malignant tumors. Surgery, radiation, and drug therapy are the main treatment modalities for gynecological cancers, with surgery being the most important of them. We started laparoscopic surgery for uterine endometrial cancer as an advanced medical treatment in 2011 and contributed to its insurance coverage. We were able to reproduce our laparoscopic surgery more easily using the da Vinci Xi system for robotic surgery. We have now switched from laparoscopic surgery for endometrial cancer to robotic surgery and have been able to perform them safely and reliably. In the case of cervical cancer, the results of the Laparoscopic Approach to Cervical Cancer (LACC) trial, which compared the prognosis of two groups of radical hysterectomy for early-stage cervical cancer: conventional open surgery and laparoscopic/robotic (minimally invasive) surgery, showed that minimally invasive surgery resulted in more pelvic recurrences and had a worse prognosis compared with open surgery. The trend toward minimally invasive surgery for cervical cancer has stagnated worldwide. Ovarian cancer has few symptoms in the early stages and is often found at stage III or IV, when the cancer has spread throughout the abdominal cavity. As residual tumor after surgery correlates with prognosis in ovarian cancer, debulking surgery should be performed to achieve complete resection. Therefore, peritoneal or bowel resection is often required to remove disseminated or metastatic tumors. We also performed prophylactic salpingo-oophorectomy to prevent ovarian and fallopian tube cancers in patients with BRCA1/2 gene variants. The uterus and ovaries are organs necessary for pregnancy and childbirth, and cancer of the uterus or ovaries in women of childbearing age may result in infertility. Surgery and adjuvant treatment may affect marriage, childbirth, and sexual life; therefore, it is important to ensure the cure of cancer and to provide patients with treatment methods that allow them to live their lives as women.

Comparison between laparoscopic and abdominal radical hysterectomy for cervical adenosquamous carcinoma at stage IA2 to IIA2: A multicenter retrospective study

OBJECTIVE

We aimed to compare the 5-year oncological outcomes of laparoscopic/abdominal radical hysterectomy (LRH/ARH) in patients with cervical adenosquamous carcinoma at stage IA2 to IIA2 based on the 2009 or 2018 International Federation of Gynecology and Obstetrics (FIGO) staging criteria.

METHODS

Based on the clinical diagnosis and treatment of cervical cancer in China (Four C) database, Cox risk regression models were applied to analyze tumor prognosis treated with ARH/LRH in FIGO 2009 and 2018 IA2-IIA2 patients and stratified findings according to tumor diameter (≤4 and >4 cm subgroups). And to avoid bias, propensity score matching (PSM) was also used for the cohort study.

RESULTS

Based on FIGO 2009 staging criteria (n = 474), there was no significant difference between the ARH and LRH groups in 5-year disease-free survival (DFS) or overall survival (OS). Lymph node metastasis was a risk factor for 5-year DFS in this stage. After PSM, lymphovascular space invasion (LVSI) was an independent risk factor for 5-year OS in the tumors ≤4 cm subgroup. Based on FIGO2018 staging criteria (n = 322), cervical interstitial infiltration depth was an independent risk factor for 5-year OS in the total population and the tumor diameter ≤4 cm subgroup.

CONCLUSIONS

Laparoscopic surgery was not a risk factor affecting the oncologic prognosis of adenosquamous carcinoma of the cervix based on either FIGO 2009 or 2018 staging of stage IA2-IIA2. In addition, LRH may be considered for patients with early-stage cervical adenosquamous carcinoma.

Results of a 20 Year Retrospective Analysis of Early-Stage Cervical Cancer: Should 3 cm Be Considered the New Ariadne's Thread in Early Cervical Cancer Treatment?

(1) This study aims to evaluate the overall survival (OS) and recurrence-free survivals (RFS) and assess disease recurrence of early-stage cervical cancer (ESCC) patients treated with minimally invasive surgery (MIS). (2) This single-center retrospective analysis was performed between January 1999 and December 2018, including all patients managed with MIS for ESCC. (3) All 239 patients included in the study underwent pelvic lymphadenectomy followed by radical hysterectomy without the use of an intrauterine manipulator. Preoperative brachytherapy was performed in 125 patients with tumors measuring 2 to 4 cm. The 5-year OS and RFS rates were 92% and 86.9%, respectively. Multivariate analysis found two significant factors associated with recurrence: previous conization with HR = 0.21, p = 0.01, and tumor size > 3 cm with HR = 2.26, p = 0.031. Out of the 33 cases of disease recurrence, we witnessed 22 disease-related deaths. Recurrence rates were 7.5%, 12.9%, and 24.1% for tumors measuring ≤ 2 cm, 2 to 3 cm, and > 3 cm, respectively. Tumors ≤ 2 cm were mostly associated with local recurrences. Tumors > 2 cm were frequently associated with common iliac or presacral lymph node recurrences. (4) MIS may still be considered for tumors ≤ 2 cm subject to first conization followed by surgery with the Schautheim procedure and extended pelvic lymphadenectomy. Due to the increased rate of recurrence, a more aggressive approach might be considered for tumors > 3 cm.

125 years of the Wertheim operation. What next?

The Austrian gynecologist Ernst Wertheim (1864-1920) was a pioneer in the surgical treatment of cancer. The principle of Wertheim's hysterectomy was to remove the uterus and the cervix with appropriate parametrium and tissues surrounding the upper vagina and pelvic lymph nodes. However, in the early 2000s, a meta-analysis of randomized trials revealed that radiotherapy and concomitant chemotherapy without surgical removal of the uterus were more effective in the historical treatment of advanced cervical cancer. This finding challenged the use of radical abdominal hysterectomy (RAH) in such cases and demonstrated the superiority of radiotherapy and chemotherapy in terms of overall survival.

The RECOURSE Study: Long-term Oncologic Outcomes Associated With Robotically Assisted Minimally Invasive Procedures for Endometrial, Cervical, Colorectal, Lung, or Prostate Cancer: A Systematic Review and Meta-analysis

OBJECTIVE

To assess long-term outcomes with robotic versus laparoscopic/thoracoscopic and open surgery for colorectal, urologic, endometrial, cervical, and thoracic cancers.

BACKGROUND

Minimally invasive surgery provides perioperative benefits and similar oncological outcomes compared with open surgery. Recent robotic surgery data have questioned long-term benefits.

METHODS

A systematic review and meta-analysis of cancer outcomes based on surgical approach was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines using Pubmed, Scopus, and Embase. Hazard ratios for recurrence, disease-free survival (DFS), and overall survival (OS) were extracted/estimated using a hierarchical decision tree and pooled in RevMan 5.4 using inverse-variance fixed-effect (heterogeneity nonsignificant) or random effect models.

RESULTS

Of 31,204 references, 199 were included (7 randomized, 23 database, 15 prospective, 154 retrospective studies)-157,876 robotic, 68,007 laparoscopic/thoracoscopic, and 234,649 open cases. Cervical cancer: OS and DFS were similar between robotic and laparoscopic [1.01 (0.56, 1.80), P =0.98] or open [1.18 (0.99, 1.41), P =0.06] surgery; 2 papers reported less recurrence with open surgery [2.30 (1.32, 4.01), P =0.003]. Endometrial cancer: the only significant result favored robotic over open surgery [OS; 0.77 (0.71, 0.83), P <0.001]. Lobectomy: DFS favored robotic over thoracoscopic surgery [0.74 (0.59, 0.93), P =0.009]; OS favored robotic over open surgery [0.93 (0.87, 1.00), P =0.04]. Prostatectomy: recurrence was less with robotic versus laparoscopic surgery [0.77 (0.68, 0.87), P <0.0001]; OS favored robotic over open surgery [0.78 (0.72, 0.85), P <0.0001]. Low-anterior resection: OS significantly favored robotic over laparoscopic [0.76 (0.63, 0.91), P =0.004] and open surgery [0.83 (0.74, 0.93), P =0.001].

CONCLUSIONS

Long-term outcomes were similar for robotic versus laparoscopic/thoracoscopic and open surgery, with no safety signal or indication requiring further research (PROSPERO Reg#CRD42021240519).

Clinical Relevance of Uterine Manipulation on Oncologic Outcome in Robot-Assisted versus Open Surgery in the Management of Endometrial Cancer

In this study, we investigated the impact of uterine manipulation on endometrial cancer survival outcomes. We analyzed patients with endometrial cancer who underwent robot-assisted staging and open staging surgery between 2010 and 2020. Either uterine manipulators or vaginal tubes were utilized in robot-assisted staging. Propensity score matching was performed to correct baseline characteristics. Progression-free survival (PFS) and overall survival (OS) were analyzed using Kaplan-Meier curve analysis. In total, 574 patients, including those undergoing robot-assisted staging with a uterine manipulator (n = 213) or vaginal tube (n = 147) and staging laparotomy (n = 214), were analyzed. Propensity score matching was performed for age, histology, and stage as covariates. Before matching, Kaplan-Meier curve analysis showed that PFS and OS were significantly different among the three groups (p < 0.001 and p = 0.009, respectively). In the propensity-matched cohorts of 147 women, the previously suggested differences in PFS and OS were not observed in patients undergoing robot-assisted staging with a uterine manipulator or vaginal tube or open surgery. In conclusion, robotic surgery using a uterine manipulator or vaginal tube did not compromise survival outcomes in endometrial cancer management.

Multi-Institutional Trends in Gynecological Robotic Surgery in India: A Real-World Scenario

Background Robot-assisted laparoscopic surgery in gynecology has grown exponentially compared to laparoscopic surgery. The probable reasons for the increased uptake of robotics are a shorter learning curve, three-dimensional vision, and increased dexterity compared to laparoscopic surgery, and precise surgery as compared to open surgery. This study compares the time trends of various parameters in robotic gynecological surgery in India over a decade. Material and methods In India, a retrospective analysis of all robot-assisted laparoscopic surgery for gynecologic diseases in five tertiary care hospitals was conducted between July 2011 and June 2021. Data were collected regarding demographic profiles, clinical and disease characteristics, and indications for surgery. Details related to surgery were collected, such as the number of ports, console and docking time, the procedure performed, total operative time, average blood loss, blood transfusion, and length of hospital stay. All the parameters collected were grouped into five years, and a comparison was made between the first five years (2011-2015) and the second five years (2016-2021). Statistical analysis, including descriptive statistics and trend analysis, was performed. Results During the 10 years, the total number of cases included was 1,501, out of which 764 were benign cases and 737 were pre-malignant/malignant cases. The common indications were uterine leiomyoma (31.2%) and carcinoma endometrium (28%). The mean age for benign cases was significantly lower than that for malignant cases (40.84 years and 55.42 years, respectively). Mean blood loss was significantly lower for benign indications (97.48 mL) than for oncological surgery (184.67 mL) and needed fewer transfusions. The mean length of stay (LOS) for benign (2.07 days) and malignant/ pre-malignant cases (2.32 days) and the mean BMI for benign (28.40) and for oncological patients (28.47) were similar in both groups. The docking time reduced significantly in the last five years. Conclusion The current retrospective study demonstrates an increasing uptake of robotic technology in gynecological surgery in India. Of the total cohort of cases, 70.9% of patients underwent gynecological robotic surgery in the last five years. A burst of adaptability happened for malignant cases in 2017 and benign cases in 2018, probably due to the increased availability of robotic platforms and improved awareness of technology and training among medical professionals. The number of cases has grown exponentially over the last five years in both benign and malignant/ pre-malignant scenarios; however, there has been a downward trend in the robotic surgery performed in the previous couple of years due to the uncertainty of the COVID pandemic.

Intraoperative frozen pathology exam of Common iliac lymph nodes and Para-Aortic lymphadenectomy on the prognosis and quality of life for patients with IB2-IIA2 Cervical Cancer: trial protocol for a randomized controlled trial (C-PACC trial)

BACKGROUND

The impact of para-aortic lymphadenectomy (PALD) on prognosis and quality of life (QoL) for IB2-IIA2 cervical cancer patients remain controversial. And whether intraoperative frozen pathology exam on common iliac lymph nodes could help predict para-aortic lymph node (PALN) metastasis was unanswered with high-level evidence.

METHODS

A multi-center, randomized controlled study is intended to investigate the effect of PALD on the prognosis and QoL in cervical cancer patients and to assess the value of intraoperative frozen pathological evaluation of common iliac nodes metastasis for the prediction of PALN metastasis. After choosing whether to receive intraoperative frozen pathological examination of bilateral common iliac lymph nodes, eligible patients will be randomly assigned (1:1) to receive PALD or not. The primary end point is 2-year progression-free survival (PFS). The secondary end points include 5-year PFS, 2-year overall survival (OS), 5-year OS, adverse events (AEs) caused by PALD, AEs caused by radiotherapy and QoL. A total of 728 patients will be enrolled from 8 hospitals in China within 3-year period and followed up for 5 years.

Advances in Robot-Assisted Surgery for Facial Bone Contouring Surgery

Since our team reported the application of robot-assisted surgery in facial contouring surgery in 2020, further clinical trials with large samples have been conducted. This paper will report the interim results of a single-center, large-sample randomized controlled trial of the first robot developed by our team for facial contouring surgery. Meanwhile, this research field will be systematically reviewed and prospected.

Impact of preoperative brachytherapy followed by radical hysterectomy in stage IB2 (FIGO 2018) cervical cancer: An analysis of SENTICOL I-II trials

INTRODUCTION

The goal of this study was to compare the outcomes of preoperative brachytherapy followed by radical surgery versus radical surgery alone in cervical cancer with tumor between 2 and 4 cm (FIGO 2018 IB2).

MATERIAL AND METHODS

SENTICOL I and SENTICOL II were two French prospective multicentric trials evaluating sentinel node biopsy in early-stage cervical cancer between 2005 and 2012. Preoperative brachytherapy (low-dose rate or pulse-dose rate at the dose of 60Gy) could be performed 6 to 8 weeks prior to the radical hysterectomy, at the discretion of each center. SENTICOL I and SENTICOL II cohorts were retrospectively analysed to compare the outcomes of preoperative brachytherapy or upfront surgery in patients with IB2 cervical tumor.

RESULTS

A total of 104 patients were included: 55 underwent upfront radical hysterectomy and 49 underwent preoperative brachytherapy followed by radical hysterectomy. Patients with preoperative brachytherapy were more likely to have no residual disease (71.4% vs. 25.5%, p < 0.0001) and to be defined as low risk according to Sedlis criteria (83.3% vs. 51.2%, p < 0.0001). Adjuvant treatments were required less frequently in case of preoperative brachytherapy (14.3% vs. 54.5%, p < 0.0001). Patients with preoperative brachytherapy experienced more postoperative complications grade ≥ 3 (24.5% vs. 9.1%, p = 0.03). Patients with preoperative brachytherapy had better 5-year disease-free survival compared to patients who underwent surgery alone, 93.6% and 74.4% respectively (p = 0.04).

CONCLUSION

Although preoperative brachytherapy was significantly associated with more severe postoperative complications, better pathologic features were obtained on surgical specimens and led to a better 5-year disease-free survival in IB2 cervical cancer.

Risk factors for catheter-associated urinary tract infections following radical hysterectomy for cervical cancer

BACKGROUND

Radical hysterectomy is the mainstay of treatment for early-stage cervical cancer. Urinary tract dysfunction is one of the most common complications after radical hysterectomy, and prolonged catheterization has previously been defined as a significant risk factor for catheter-associated urinary tract infections.

OBJECTIVE

This study aimed to determine the rate of catheter-associated urinary tract infections after radical hysterectomy for cervical cancer, and to identify additional risk factors for developing catheter-associated urinary tract infections in this population.

STUDY DESIGN

We reviewed patients who underwent radical hysterectomy for cervical cancer from 2004 to 2020 after institutional review board approval. All patients were identified from institutional Gynecologic Oncology surgical and tumor databases. The inclusion criterion was radical hysterectomy for early-stage cervical cancer. Exclusion criteria included inadequate hospital follow-up, insufficient records of catheter use in the electronic medical record, urinary tract injury, and preoperative chemoradiation. Catheter-associated urinary tract infection was defined as an infection diagnosed in a catheterized patient or within 48 hours of catheter removal, with significant bacteriuria (>10³ cfu/mL) and symptoms or signs attributable to the urinary tract. Data analysis was performed using comparative analysis and univariate and multivariable logistic regression using Excel, GraphPad Prism, and IBM SPSS Statistics.

RESULTS

Of the 160 included patients, 12.5% developed catheter-associated urinary tract infections. In univariate analysis, catheter-associated urinary tract infection was significantly associated with current smoking history (odds ratio, 3.76; 95% confidence interval, 1.39-10.08), minimally invasive surgical approach (odds ratio, 5.24; 95% confidence interval, 1.91-16.87), estimated surgical blood loss >500 mL (odds ratio, 0.18; 95% confidence interval, 0.04-0.57), operative time >300 minutes (odds ratio, 2.92; 95% confidence interval, 1.07-9.36), and increased duration of catheterization (odds ratio, 18.46; 95% confidence interval, 3.67-336). After adjusting for interactions and controlling for potential confounders with multivariable analysis, current smoking history and catheterization for >7 days were identified as independent risk factors for development of catheter-associated urinary tract infections (adjusted odds ratio, 3.94; 95% confidence interval, 1.28-12.37; adjusted odds ratio, 19.49; 95% confidence interval, 2.78-427).

CONCLUSION

Preoperative smoking cessation interventions for current smokers should be implemented to decrease risk for postoperative complications, including catheter-associated urinary tract infections. In addition, catheter removal within 7 postoperative days should be encouraged in all women undergoing radical hysterectomy for early-stage cervical cancer in an effort to decrease infection risk.

Circulating Tumor Cell Detection by Liquid Biopsy during Early-Stage Endometrial Cancer Surgery: A Pilot Study

The recurrence of non-metastatic endometrial carcinoma (EC) (6 to 21%) might be due to disseminated tumor cells. This feasibility study investigated whether circulating tumor cells (CTCs) were detectable in blood samples from the peripheral and ovarian veins of 10 patients undergoing laparoscopic resection of stage I-II EC between July 2019 and September 2021. CTCs were detected using the CellSearch® system (i) preoperatively (T0) in peripheral blood, (ii) after ovary suspensory ligament pediculation in ovarian vein blood (T1), and (iii) before colpotomy in peripheral blood (T2). CTCs were detected only in ovarian vein samples in 8/10 patients. The CTC median number did not differ with patient age (37 (min-max: 0–91) in <70-year-old vs. 11 (0–65) in ≥70 year-old women, p = 0.59), tumor grade (15 (0–72) for grade 1 vs. 15 (0–91) for grade 2, p = 0.97), FIGO stage (72 (27–91) vs. 2 (0–65) vs. 3 (0–6]) for stage IA, B, and II, respectively; p = 0.08), and tumor size (40 (2–72) for size < 30 mm vs. 4 (0–91) for size ≥ 30 mm, p = 0.39). Estrogen receptor-positive CTCs and CTC clusters were identified. The prognostic and therapeutic values of CTCs released during EC surgery need to be determined.

Postchemotherapy robotic retroperitoneal lymph node dissection for non-seminomatous germ cell tumors in the lateral decubitus position: oncological and functional outcomes

PURPOSE

Retroperitoneal lymph node dissection (RPLND) is recommended for residual masses following chemotherapy for non-seminomatous germ cell tumors (NSGCT). Recently, aberrant recurrence patterns were reported in patients who underwent robotic RPLND. We aimed to evaluate perioperative safety in addition to functional and early oncological outcomes of postchemotherapy robotic RPLND (pcR-RPLND) for NSGCT.

METHODS

A total of 25 patients with NSGCT who underwent a pcR-RPLND between January 2011 and June 2022 were evaluated retrospectively. Descriptive statistics were provided for demographics, clinical characteristics, intraoperative and postoperative parameters. Functional and oncological outcomes were recorded.

RESULTS

The median patient age was 28.9 years (IQR 21.5-32.4). The median retroperitoneal tumor size was 2.6 cm (IQR 1.5-3.5). Intraoperative complications occurred in only one case and the open conversion rate was 12%. There were seven cases with postoperative complications (Clavien grade II: 5 and IIIa: 2). Patients were followed for a median of 33.2 months (IQR 14.8-43.0). Antegrade ejaculation was preserved in 85.7% of the patients. Two patients (8%) relapsed and both had out-of-field recurrences at unusual sites (perinephric fat and omentum). Of those, one patient died (4%) of testicular cancer.

CONCLUSION

pcR-RPLND is a feasible and technically reproducible procedure with favorable perioperative morbidity, low rate of complications, and acceptable postoperative ejaculatory function. Although the recurrence rate was low (8%), recurrences were observed at unusual sites. Further studies are required to investigate any association between the robotic approach and aberrant recurrence patterns.

Beyond Sentinel Lymph Node: Outcomes of Indocyanine Green-Guided Pelvic Lymphadenectomy in Endometrial and Cervical Cancer

BACKGROUND

The aim of our study was to compare the number of lymph nodes removed during indocyanine green (ICG)-guided laparoscopic/robotic pelvic lymphadenectomy with standard systematic lymphadenectomy in endometrial cancer (EC) and cervical cancer (CC).

METHODS

This is a multicenter retrospective comparative study (Clinical Trial ID: NCT04246580; updated on 31 January 2023). Women affected by EC and CC who underwent laparoscopic/robotic systematic pelvic lymphadenectomy, with (cases) or without (controls) the use of ICG tracer injection within the uterine cervix, were included in the study.

RESULTS

The two groups were homogeneous for age (p = 0.08), Body Mass Index, International Federation of Gynaecology and Obstetrics (FIGO) stages (p = 0.41 for EC; p = 0.17 for CC), median estimated blood loss (p = 0.76), median operative time (p = 0.59), and perioperative complications (p = 0.66). Nevertheless, the number of lymph nodes retrieved during surgery was significantly higher (p = 0.005) in the ICG group (n = 18) compared with controls (n = 16).

CONCLUSIONS

The accurate and precise dissection achieved with the use of the ICG-guided procedure was associated with a higher number of lymph nodes removed in the case of systematic pelvic lymphadenectomy for EC and CC.

Effect of annualized surgeon volume on major surgical complications for abdominal and laparoscopic radical hysterectomy for cervical cancer in China, 2004-2016: a retrospective cohort study

BACKGROUND

Previous studies have suggested that higher surgeon volume leads to improved perioperative outcomes for oncologic surgery; however, the effect of surgeon volumes on surgical outcomes might differ according to the surgical approach used. This paper attempts to evaluate the effect of surgeon volume on complications or cervical cancer in an abdominal radical hysterectomy (ARH) cohort and laparoscopic radical hysterectomy (LRH) cohort.

METHODS

We conducted a population-based retrospective study using the Major Surgical Complications of Cervical Cancer in China (MSCCCC) database to analyse patients who underwent radical hysterectomy (RH) from 2004 to 2016 at 42 hospitals. We estimated the annualized surgeon volumes in the ARH cohort and in the LRH cohort separately. The effect of the surgeon volume of ARH or LRH on surgical complications was examined using multivariable logistic regression models.

RESULTS

In total, 22,684 patients who underwent RH for cervical cancer were identified. In the abdominal surgery cohort, the mean surgeon case volume increased from 2004 to 2013 (3.5 to 8.7 cases) and then decreased from 2013 to 2016 (8.7 to 4.9 cases). The mean surgeon case volume number of surgeons performing LRH increased from 1 to 12.1 cases between 2004 and 2016 (P < 0.01). In the abdominal surgery cohort, patients treated by intermediate-volume surgeons were more likely to experience postoperative complications (OR = 1.55, 95% CI = 1.11-2.15) than those treated by high-volume surgeons. In the laparoscopic surgery cohort, surgeon volume did not appear to influence the incidence of intraoperative or postoperative complications (P = 0.46; P = 0.13).

CONCLUSIONS

The performance of ARH by intermediate-volume surgeons is associated with an increased risk of postoperative complications. However, surgeon volume may have no effect on intraoperative or postoperative complications after LRH.

Robotic Versus Open Cystectomy for Bladder Cancer: Synthesizing the Data from Current Systematic Reviews and Meta-Analyses

This is a summary of existing systematic reviews comparing robotic assisted radical cystectomy (RARC) with open radical cystectomy (ORC). Our aim was to compare operative approaches with respect to perioperative, postoperative, oncologic, and health-related quality of life (QOL) outcomes. We performed a systematic review of MEDLINE, Medline-in-Process and Medline Epubs Ahead of Print, and the Cochrane Library on 22 February 2022. We included reviews of adult patients with bladder cancer undergoing RARC or ORC for muscle invasive or high-risk non-muscle invasive bladder cancer. Nonrandomized studies were excluded to minimize confounding and selection bias. The GRADE approach was used to determine the confidence in estimates. We assessed the quality of identified systematic reviews using AMSTAR 2 checklist. Six well-conducted, systematic reviews and meta-analyses were included. RARC was consistently associated with lower estimated blood loss (EBL) and transfusion rates, and longer operative time. There was inconsistent evidence for the impact of RARC on hospital length of stay (LOS). There was no significant difference in overall complication rate or major complication rate, or oncologic outcomes between groups. Comparison of QOL outcomes between studies was limited by statistical and methodological heterogeneity. RARC is associated with improvement in EBL and transfusion risk. There does not appear to be differences in oncologic outcomes or complications between approaches. Prospective studies are needed to assess the impact of diversion type, technique, and recovery pathways on patient outcomes and to assess the impact of operative approach on cost and patient-reported QOL.

Ultrastaging of the Parametrium in Cervical Cancer: A Clinicopathological Study

Occult parametrial involvement in apparent early-stage cervical cancer might be overlooked with standard pathologic assessment. The primary endpoint of the present study was to assess the rate of positive parametrial lymph nodes and of microscopic continuous or discontinuous parametrial involvement. This is a retrospective, single-center, observational study including patients with FIGO 2018 stage IA1-IIA1 and IIIC1p in whom bilateral sentinel lymph node (SLN) detection and ultrastaging of SLN were performed according to institutional protocol, with surgery as primary treatment performed between May 2017 and February 2021, as well as type B2/C1/C2 (Querleu-Morrow) radical hysterectomy and usual histology (squamous cell, adenocarcinoma and adenosquamous carcinoma). Thirty-one patients were included in the study period. Six (18.7%) patients had metastatic lymph nodes, of whom four had only SLN metastasis (two cases of ITC, one case of micrometastasis and one case of macrometastasis). We found a macroscopic deposit of cancer cells in the parametrial lymph node of one patient (3.1%). There was a positive statistical correlation between the incidence of parametrial lymph node involvement and the metastatic pelvic lymph nodes (p = 0.038). When performed per patient, the sensitivity, negative predictive value and accuracy of parametrial lymph node involvement in predicting pelvic lymph node metastasis were 16.7%, 83.3% and 83.9%, respectively. Ultrastaging of parametrial tissue did not identify any occult continuous or discontinuous parametrial metastasis. In conclusion, the incidence of lymph node parametrial involvement in a retrospective series of early-stage cervical cancer was 3.1% of all included patients. Lymph node involvement of the parametrium was associated with lymph node metastasis. The sensitivity of parametrial lymph node involvement to predict pelvic lymph node metastasis was low. The lack of parametrial involvement revealed by parametrial ultrastaging could be related to the number of patients with tumors with a pathologic diameter < 2 cm (54.8%). Further prospective studies are needed to analyze the role of parametrial ultrastaging in early-stage cervical cancer and to assess whether it can be considered the "sentinel" of the sentinel lymph node.

Robot-assisted retroperitoneal lymph node dissection: a systematic review of perioperative outcomes

OBJECTIVE

To assess the safety and feasibility of robot-assisted retroperitoneal lymph node dissection (R-RPLND) and to compare the perioperative outcomes of R-RPLND with open RPLND (O-RPLND), as RPLND forms an integral part of the management of testis cancer and R-RPLND is a minimally invasive treatment option for this disease.

MATERIALS AND METHODS

The PubMed^® , Scopus^® , Cochrane Central Register of Controlled Trials, and Web of Science™ databases were searched for studies reporting perioperative outcomes of primary and post-chemotherapy R-RPLND and studies comparing R-RPLND with O-RPLND.

RESULTS

The search yielded 42 articles describing R-RPLND, including five comparative studies. The systematic review included 4222 patients (single-arm studies, n = 459; comparative studies, n = 3763). Of 459 patients in the single-arm studies, 271 underwent primary R-RPLND and 188 underwent post-chemotherapy R-RPLND. For primary R-RPLND, the operative time ranged from 175 to 540 min and the major complication rate was 4.1%. For post-chemotherapy R-RPLND, the operative time ranged from 134 to 550 min and the major complication rate was 8.5%. The conversion rate to open surgery was 2.2% in primary R-RPLND and 9.0% in post-chemotherapy R-RPLND. In comparison with O-RPLND, R-RPLND was associated with a lower transfusion rate (14.5% vs 0.9%, P < 0.001) and a lower complication rate (18.5% vs 7.8%, P = 0.002).

CONCLUSION

Robot-assisted RPLND has acceptable perioperative outcomes in both the primary and post-chemotherapy settings but a notable rate of conversion to open surgery in the post-chemotherapy setting. Compared with O-RPLND, R-RPLND is associated with a lower transfusion rate and fewer overall complications. Given the potential impact of selection bias, the optimal patient selection criteria for R-RPLND remain to be elucidated.

Oncologic Outcomes of Surgically Treated Cervical Cancer with No Residual Disease on Hysterectomy Specimen: A 4C (Canadian Cervical Cancer Collaborative) Working Group Study

Minimally invasive surgery for the treatment of macroscopic cervical cancer leads to worse oncologic outcomes than with open surgery. Preoperative conization may mitigate the risk of surgical approach. Our objective was to describe the oncologic outcomes in cases of cervical cancer initially treated with conization, and subsequently found to have no residual cervical cancer after hysterectomy performed via open and minimally invasive approaches. This was a retrospective cohort study of surgically treated cervical cancer at 11 Canadian institutions from 2007 to 2017. Cases initially treated with cervical conization and subsequent hysterectomy, with no residual disease on hysterectomy specimen were included. They were subdivided according to minimally invasive (laparoscopic/robotic (MIS) or laparoscopically assisted vaginal/vaginal hysterectomy (LVH)), or abdominal (AH). Recurrence free survival (RFS) and overall survival (OS) were estimated using Kaplan-Meier analysis. Chi-square and log-rank tests were used to compare between cohorts. Within the total cohort, 238/1696 (14%) had no residual disease on hysterectomy specimen (122 MIS, 103 AH, and 13 VLH). The majority of cases in the cohort were FIGO 2018 stage IB1 (43.7%) and underwent a radical hysterectomy (81.9%). There was no statistical difference between stage, histology, and radical vs simple hysterectomy between the abdominal and minimally invasive groups. There were no significant differences in RFS (5-year: MIS/LVH 97.7%, AH 95.8%, p = 0.23) or OS (5-year: MIS/VLH 98.9%, AH 97.4%, p = 0.10), although event-rates were low. There were only two recurrences. In this large study including only patients with no residual cervical cancer on hysterectomy specimen, no significant differences in survival were seen by surgical approach. This may be due to the small number of events or due to no actual difference between the groups. Further studies are warranted.

Role of minimally invasive secondary cytoreduction in patients with recurrent ovarian cancer

OBJECTIVE

Retrospective series have shown minimally invasive secondary cytoreductive surgery is a feasible approach in selected cases of recurrent ovarian cancer. However, no predictors of minimally invasive secondary cytoreductive surgery feasibility are currently available. This study aims to identify predictive factors of minimally invasive secondary cytoreductive surgery feasibility and to compare perioperative and survival outcomes in a matched series of recurrent ovarian cancer patients who underwent secondary cytoreduction via an open or minimally invasive surgical approach.

METHODS

We retrospectively identified all platinum-sensitive recurrent epithelial ovarian cancer patients who underwent minimally invasive or laparotomic secondary cytoreductive surgery between January 2013 and July 2020. Each patient underwent a preoperative positron emission tomography (PET) computerized tomography (CT) scan and diagnostic laparoscopy before secondary cytoreductive surgery. A 1:2 propensity score-matched analysis was performed to balance predictive factors of minimally invasive secondary cytoreductive surgery.

RESULTS

Overall, 276 patients were identified (62 minimally invasive and 214 open), and a complete gross resection was achieved in 262 (94.9%) patients. At multivariate analysis, predictive factors for minimally invasive secondary cytoreductive surgery were neoadjuvant chemotherapy at first diagnosis (p=0.007), site of recurrence (p=0.031), and number of lesions (p=0.001). In the 1:2 propensity-matched population (39 minimally invasive and 78 open), complete gross resection was similar for both groups (p=0.082). Early post-operative complications were significantly higher in the laparotomy (33.3%) than in the minimally invasive surgery (10.3%) group (p=0.004). Only one (2.6%) patient experienced a grade >3 early post-operative complication in the minimally invasive surgery group compared with 13 (16.7%) patients in the open cohort (p<0.001). The median follow-up period was 32 months (range: 1-92) in the propensity-matched population. The median post-recurrence survival was 81 months in the minimally invasive surgery group and was not reached in the open group (p=0.11).

CONCLUSIONS

Patients with single or oligometastatic recurrences can be offered minimally invasive secondary cytoreductive surgery, mainly if localized in the lymph-nodes, and/or if they received neoadjuvant chemotherapy at primary diagnosis. Minimally invasive secondary cytoreductive surgery is associated with favorable perioperative outcomes with no differences in terms of post-recurrence survival with respect to open approach.

Minimally invasive versus open pelvic exenteration in gynecological malignancies: a propensity-matched survival analysis

OBJECTIVE

The primary endpoint of this study was to compare the disease-free survival of patients undergoing open versus minimally invasive pelvic exenteration. The secondary endpoints were cancer-specific survival and peri-operative morbidity.

METHODS

A multi-center, retrospective, observational cohort study was undertaken. Patients undergoing curative and palliative anterior or total pelvic exenteration for gynecological cancer by a minimally invasive approach and an open approach between June 2010 and May 2021 were included. Patients with distant metastases were excluded. A 1:2 propensity match analysis between patients undergoing minimally invasive and open pelvic exenteration was performed to equalized baseline characteristics.

RESULTS

After propensity match analysis a total of 117 patients were included, 78 (66.7%) and 39 (33.3%) in the open and minimally invasive group, respectively. No significant difference in intra-operative (23.4% vs 10.3%, p=0.13) and major post-operative complications (24.4% vs 17.9%, p=0.49) was evident between the open and minimally invasive approach. Patients undergoing open pelvic exenteration received higher rates of intra-operative transfusions (41.0% vs 17.9%, p=0.013). Median disease-free survival was 17.0 months for both the open and minimally invasive groups (p=0.63). Median cancer-specific survival was 30.0 months and 26.0 months in the open and minimally invasive groups, respectively (p=0.80). Positivity of surgical margins at final histology was the only significant factor influencing the risk of recurrence (hazard ratio (HR) 2.38, 95% CI 1.31 to 4.31) (p=0.004), while tumor diameter ≥50 mm at the time of pelvic exenteration was the only significant factor influencing the risk of death (HR 1.83, 95% CI 1.08 to 3.11) (p=0.025).

CONCLUSION

In this retrospective study no survival difference was evident when minimally invasive pelvic exenteration was compared with open pelvic exenteration in patients with gynecological cancer. There was no difference in peri-operative complications, but a higher intra-operative transfusion rate was seen in the open group.

Prognostic Significance of Ultrasound Characteristics and Body Mass Index in Patients with Apparent Early-Stage Cervical Cancer: A Single-Center, Retrospective, Cohort Study

The primary aim of the present study was to investigate the prognostic impact (defined as disease-free-DFS and overall survival-OS) of the ultrasound scan tumor parameters, patients' anthropometric parameters, and their combination in early-stage cervical cancer. The secondary aim was to assess the relation between ultrasound characteristics and pathological parametrial infiltration. This is a retrospective, single-center, observational cohort study. Consecutive patients with clinical FIGO 2018 stage IA1-IB2 and IIA1 cervical cancer who underwent preoperative ultrasound examination and radical surgery between 02/2012 and 06/2019 were included. Patients who underwent neo-adjuvant treatment, fertility sparing surgery, and pre-operative conization were excluded. Data from 164 patients were analyzed. Body mass index (BMI) ≤20 Kg/m² (p < 0.001) and ultrasound tumor volume (p = 0.038) were related to a higher risk of recurrence. The ratios between ultrasound tumor volume and BMI, ultrasound tumor volume and height, and ultrasound largest tumor diameter and BMI were significantly related to a higher risk of recurrence (p = 0.011, p = 0.031, and p = 0.017, respectively). The only anthropometric characteristic related to a higher risk of death was BMI ≤20 Kg/m² (p = 0.021). In the multivariate analysis, the ratio between ultrasound-measured largest tumor diameter and cervix-fundus uterine diameter (with 37 as the cut-off) was significantly associated with pathological microscopic parametrial infiltration (p = 0.018). In conclusion, a low BMI was the most significant anthropometric biomarker impairing DFS and OS in patients with apparent early-stage cervical cancer. The ratios between ultrasound tumor volume and BMI, ultrasound tumor volume and height, and ultrasound largest tumor diameter and BMI significantly affected DFS but not OS. The ratio between ultrasound-measured largest tumor diameter and cervix-fundus uterine diameter was related to parametrial infiltration. These novel prognostic parameters may be useful in pre-operative workup for a patient-tailored treatment in early-stage cervical cancer.

Does the Use of a Uterine Manipulator or Intracorporeal Colpotomy Confer an Inferior Prognosis in Minimally Invasive Surgery-Treated Early-stage Cervical Cancer?

STUDY OBJECTIVE

To identify whether the use of a uterine manipulator (UM) or intracorporeal colpotomy conferred inferior short-term survival among patients treated for early-stage cervical cancer.

DESIGN

Retrospective cohort study.

SETTING

Tertiary university-based hospital.

PATIENTS

1169 patients with stage IB1 to IB2 cervical cancer.

INTERVENTIONS

All patients underwent minimally invasive radical hysterectomy and pelvic lymphadenectomy.

MEASUREMENTS AND MAIN RESULTS

A total of 1169 patients diagnosed with preoperative stage IB1 to IB2 cervical cancer were primarily treated with surgery from 2018 to 2019. The eligible patients had a median age of 48 years (range, 23-76 years), and the median follow-up time was 34 months (range, 3.57-50.87 months). The 2-year overall survival rate of the patients with pathologic stage IB1 and IB2 was 99.8% and 98.8%, respectively, according to the 2018 International Federation of Gynecology and Obstetrics staging system. Univariable analysis revealed that the UM group had a 7.6-times higher risk of death than that of the manipulator-free group (p = .006), but multivariable analysis clarified that only tumor size (p = .016; hazard ratio, 2.285; 95% confidence interval, 1.166-4.479) and parametrial involvement (p = .003; hazard ratio, 3.556; 95% confidence interval, 1.549-8.166) were independent risk factors for overall survival. There was no statistically significant difference in survival between patients who underwent intracorporeal and protective colpotomy.

CONCLUSION

Short-term survival outcomes in women undergoing minimally invasive radical hysterectomy for treatment of early-stage cervical cancer did not differ when a UM was avoided or when a protective colpotomy was performed.

Ergonomic Assessment of the Surgeon's Physical Workload During Robot-Assisted Versus Standard Laparoscopy in a French Multicenter Randomized Trial (ROBOGYN-1004 Trial)

BACKGROUND

Standard laparoscopy (SL) is responsible for musculoskeletal disorders in surgeons because of poor ergonomic positions, which could be reduced by robot-assisted laparoscopy (RAL) owing to the surgeons' seated position. One of the aims of the ROBOGYN-1004 study (NCT01247779) was to evaluate surgeons' workloads during real-time procedures of gynecological oncological surgery.

METHODS

Patients with gynecological cancer eligible for minimally invasive surgery were recruited from 13 French centers between December 2010 and December 2015. Physical workload was evaluated using the Borg scale every hour over the surgery duration and the perception of workload evaluated using NASA-TLX at the end of surgery.

RESULTS

A total of 369 patients were recruited, of whom 176 underwent RAL and 193 underwent SL (per-protocol analysis). Posture during SL was significantly more challenging for all body parts except the back. There was an increase in discomfort over time (up to 4 h) for the hands and arms, neck, and legs in SL compared with RAL. Perceived physical activity and abilities were rated higher in SL than in RAL (p < 0.01), whereas perceived personal performance was higher in SL (p < 0.01). Perceived physical effort during surgery was lower in RAL than in SL.

CONCLUSIONS

RAL improves the perception of physical workload. Compared with SL, the perceived effort is lower in RAL regardless of the complexity of the surgery.

Role of laparoscopic hysterectomy in cervical and endometrial cancer: a narrative review

Endometrial cancer is the most common carcinoma of the female genital organs and cervical cancer is the leading cause of cancer death in women worldwide. The aim of this review is to evaluate the role of laparoscopic hysterectomy in patients with endometrial and cervical cancer in this period, and analyze the outcome of hysterectomy in terms of survival. Moreover, we present the historical background, new techniques, the anatomical features, and surgical steps of radical hysterectomy. According to new evidence, minimally invasive surgery in patients with cervical cancer is associated with higher rates of recurrence and mortality compared to the open approach. Despite the numerous explanations offered for this phenomenon, the reasons for these results are unclear. Additional large trials have been launched to reevaluate the above-mentioned data. On contrary, the laparoscopic approach provides surgical outcomes and similar survival rates as open surgery in patients with early endometrial carcinoma. Furthermore, the radicality of hysterectomy does not influence local recurrence rates or overall survival in cases with complete surgical removal of the tumor. A laparoscopic radical hysterectomy is no longer an option in patients with cervical cancer. When minimally invasive surgery is offered, the patients must be counseled in detail about the current debate.

Comparison of minimally invasive versus open pelvic organ-preserving radical cystectomy in female patients with bladder cancer: a multicenter propensity score matching analysis

PURPOSE

To compare the perioperative and oncologic outcomes between minimally invasive pelvic organ-preserving radical cystectomy (MIPOPRC) and open pelvic organ-preserving radical cystectomy (open POPRC) among female patients with bladder cancer (BCa).

METHODS

We identified female patients who underwent POPRC for BCa at three centers between January 2006 and April 2018. Female patients who underwent open POPRC were matched with those who underwent MIPOPRC using 1:1 propensity score (PS) matching. The patient demographics and perioperative and oncologic outcomes were evaluated for the comparison between MIPOPRC and open POPRC.

RESULTS

Among the 158 patients enrolled, 83 patients underwent MIPOPRC, and 75 underwent open POPRC. A total of 60 MIPOPRC and 60 open POPRC patients were matched successfully. The cancer-specific survival (CSS) and recurrence-free survival (RFS) did not differ significantly in the propensity score-weighted cohort (p = 0.297 and p = 0.600, respectively). Subgroup analysis by age and pathologic stage in the matched cohort revealed that CSS and RFS were with no differences among all subgroups. Moreover, multivariable Cox regression analyses showed that the surgical approach (MIPOPRC vs open POPRC) was not a predictor of CSS (p = 0.250).

CONCLUSION

MIPOPRC was non-inferior to open POPRC in terms of oncologic outcomes among female patients. MIPOPRC could be technically feasible in selected female patients with BCa.

Two lateral parametria in radical hysterectomy: History and outcome

AIM

Some anatomic concepts for 20th century radical hysterectomy (RH) did not conform to progress in surgical technique. The purpose of this article was to put forward a new practical anatomy and application to surgical procedures.

METHODS

Following a historical review the author reexamined his surgical procedures from 1980 to 2005 on 131 patients with cervical cancer. One hundred and eight of these patients had undergone RH and 23 super RH plus neoadjuvant chemotherapy, 7 had RH combined with a total mesorectal excision because of infiltration into the lateral rectal ligament due to rectal cancer. Also reviewed were data on surgical procedures and anatomy following a series of mock RH on 26 donated female cadavers.

RESULTS

It was found that the cardinal ligament and transverse cervical ligament must be distinguished. The vesicohypogastric fascia, transverse cervical ligament, and lateral rectal ligament formed a continuum with their relationship to the organs being perpendicular. The surgical technique for an RH is total excision of the transverse cervical ligament, whereas the one for a semi-RH is partial or total excision of the deep uterine vein. The paracolpium is the caudal extension of the cardinal ligament, not the medial extension of the superior fascia of pelvic diaphragm.

CONCLUSION

New practical anatomy and surgical technique were established through recognition of morphology of the living body being transformed by surgical maneuvers.

Proof-of-concept randomized phase II non-inferiority trial of simple versus type B2 hysterectomy in early-stage cervical cancer ≤2 cm (LESSER)

OBJECTIVE

To evaluate the non-inferiority and safety of simple hysterectomy in early stage (<2 cm) cervical cancer.

METHODS

This proof-of-concept randomized phase II non-inferiority trial was performed between May 2015 and April 2018 in three oncological centers in Northeast Brazil. Patients with International Federation of Gynecology and Obstetrics (FIGO) 2009 stages IA2-IB1 cervical cancer and tumors ≤2 cm were treated with either simple or modified radical hysterectomy (Querleu-Morrow type B2). Intention-to-treat analysis was carried out. The primary endpoint was 3-year disease-free survival and secondary endpoints were overall survival, operative outcomes, adjuvant therapy, and patient's health-related quality of life (QoL).

RESULTS

A total of 40 patients underwent either simple hysterectomy (n=20) or modified radical hysterectomy (n=20). All patients except three underwent open procedures (n=37/40, 92.5%). At a median follow-up of 52.1 months (IQR 43.9-60.1), 3-year disease-free survival was 95% (95% CI 68% to 99%) after simple hysterectomy and 100% (95% CI 100% to 100%) after modified radical hysterectomy (log-rank p=0.30). The corresponding 5-year overall survival rates were 90% (95% CI 64% to 97%) and 91% (95% CI 50% to 98%), respectively (log-rank p=0.46). The operative time was shorter after simple hysterectomy than after modified radical hysterectomy (150 min (IQR 137.5-180) vs 199.5 min (IQR 140-230); p=0.003), with a trend towards a longer time for vesical catheterization removal (1 day (IQR 1-1) vs 1 day (IQR 1-2); p=0.043). There was no post-operative mortality and the rates of post-operative complications were not statistically different between arms (15% and 25%; p=0.69). QoL questionnaires were received from only 17 patients (42.5%), with no major differences observed over time between the surgical arms.

CONCLUSIONS

Simple hysterectomy is safe and potentially non-inferior to the radical surgery in patients with early-stage cervical cancer ≤2 cm.

Learning Laparoscopic Radical Hysterectomy: Are We Facing an Emerging Situation?

Despite wide screening campaigns and early detection, cervical cancer remains the fourth most common cancer among women. Radical hysterectomy, whether by open, laparoscopic or by robotic-assisted techniques, is the mainstay treatment. However, for adequate surgical results and good oncological prognosis, a gynecological surgeon should be trained to perform those procedures. The learning curve of radical hysterectomy, especially by laparoscopy, is influenced by several factors. The LACC trial, the decrease in cervical cancer incidence and radical hysterectomy procedures have widely reduced the learning curve for surgeons. This article mainly discusses the learning curve of laparoscopic radical hysterectomy for cervical cancers, and how several factors are influencing it negatively, with the need to have medical authorities reset specific surgical training programs and allocate them to special oncological centers.

Meta-analysis of laparoscopic radical hysterectomy, excluding robotic assisted versus open radical hysterectomy for early stage cervical cancer

Recent evidence has shown an increase in recurrence and a decrease in overall survival in patients treated with laparoscopic radical hysterectomy (LRH) and robotic assisted radical hysterectomy (RRH) open techniques (ORH). In addition, several high quality trials were recently published regarding the laparoscopic treatment of early stage cervical cancer. We sought out to reassess the recurrence rates, overall survival, complications and outcomes associated with laparoscopic radical hysterectomy (LRH) techniques against open techniques (ORH) when robotic assisted techniques were excluded. We searched PubMed, Medline, Cochrane CENTRAL, SCOPUS, ClinicalTrials.Gov and Web of Science for relevant clinical trials and observational studies. We included all studies that compared with early stage cervical cancer receiving LRH compared with ORH. We included randomized clinical trials, prospective cohort, and retrospective cohort trials. We included studies that included LRH and RRH as long as data was available to separate the two arms. We excluded studies that combined LRH and RRH without supplying data to differentiate. Of 1244 total studies, we used a manual three step screening process. Sixty studies ultimately met our criteria. We performed this review in accordance with PRISMA guidelines. We analyzed continuous data using mean difference (MD) and a 95% confidence interval (CI), while dichotomous data were analyzed using odds ratio (OR) and a 95% CI. Review Manager and Endnote software were utilized in the synthesis. We found that when excluding RRH, the was no significant difference regarding 5-year overall Survival (OR = 1.24 [0.94, 1.64], (P = 0.12), disease free survival (OR = 1.00 [0.80, 1.26], (P = 0.98), recurrence (OR = 1.01 [0.81, 1.25], (P = 0.95), or intraoperative complications (OR = 1.38 [0.94, 2.04], (P = 0.10). LRH was statistically better than ORH in terms of estimated blood loss (MD = - 325.55 [- 386.16, - 264.94] (P < 0.001), blood transfusion rate (OR = 0.28 [0.14, 0.55], (P = 0.002), postoperative complication rate (OR = 0.70 [0.55, 0.90], (P = 0.005), and length of hospital stay (MD = - 3.64[- 4.27, - 3.01], (P < 0.001). ORH was superior in terms of operating time (MD = 20.48 [8.62, 32.35], (P = 0.007) and number of resected lymph nodes (MD = - 2.80 [- 4.35, - 1.24], (P = 0.004). The previously seen increase recurrence and decrease in survival is not seen in LRH when robotic assisted techniques are included and all new high quality is considered. LRH is also associated with a significantly shorter hospital stay, less blood loss and lower complication rate.Prospero Prospective Registration Number: CRD42022267138.

Survival after laparoscopic radical surgery for stage IA-IIB cervical cancer: 1316 consecutive cases from a national laparoscopic training center in China

BACKGROUND

To investigate the survival of cervical cancer patients undergoing laparoscopic radical hysterectomy (LRH) in a minimally invasive gynecology center.

METHODS

A consecutive series of patients undergoing first LRH for cervical cancer from May 2008 to December 2017 at a national laparoscopic training center was retrospectively analyzed. The overall survival (OS) and progression-free survival (PFS) were compared between groups.

RESULTS

In total, 1316 women with FIGO (2009) stage IA-IIB cervical cancer received LRH. Among them, 1114 (84.7%) were followed up for 3 months or longer; the median follow-up period was 48 months (range 3-144 months). In patients with stage IA, IB1 (≤ 2 cm), IB1 (> 2 cm), IB2, IIA1 and IIA2-IIB tumors, the 4-year PFS rates were 98.6, 94.5, 87.4, 65.6, 80.0 and 67.4%, respectively, and the 4-year OS rates were 98.6, 96.8, 91.1, 77.4, 85.6 and 76.2%, respectively. The 4-year PFS and OS were as high as 96.2 and 97.5%, respectively, in patients with squamous cell carcinoma of 2 cm or smaller in diameter. A stable high 4-year OS and PFS was achieved after completing 100 LRHs. In patients operated on by the same surgeon, an improvement in survival was observed after 40 LRHs.

CONCLUSION

Favorable oncologic outcomes can be achieved in patients with IA-IB1 cervical cancer after LRH in a center with a high surgery volume.

Comparison of oncological outcomes in elderly early-stage cervical cancer patients treated with radical surgery or radiotherapy: A real-world retrospective study with propensity score matching

Objective

To compare the oncological outcomes of radical surgery and radical radiotherapy in elderly (over 65 years) patients with early-stage cervical cancer (IB-IIA).

Methods

Elderly patients with stage IB-IIA cervical cancer treated at Peking Union Medical College Hospital from January 2000 to December 2020 were retrospectively reviewed. All patients were divided into the radiotherapy group (RT group) and the operation group (OP group) according to their primary intervention. Propensity score matching (PSM) analysis was performed to balance the biases. The primary outcome was overall survival (OS), and the secondary outcomes were progression-free survival (PFS) and adverse effects.

Results

A total of 116 patients were eligible for the study (47 in the RT group, and 69 in the OP group), and after PSM, 82 patients were suitable for further analysis (37 in the RT group, and 45 in the OP group). In the real-world setting, it was found that compared with radiotherapy, operation was more frequently selected for elderly cervical cancer patients with adenocarcinoma (P < 0.001) and IB1 stage cancer (P < 0.001). The 5-year PFS rates between the RT and OP groups were not significant (82.3% vs. 73.6%, P = 0.659), and the 5-year OS rate of the OP group was significantly better than that in the RT group (100% vs. 76.3%, P = 0.039), especially in patients with squamous cell carcinoma (P = 0.029) and tumor size of 2~4 cm with G2 differentiation (P = 0.046). There was no significant difference in PFS between the two groups (P = 0.659). In the multivariate analysis, compared with operation, radical radiotherapy was an independent risk factor of OS (hazard ratio = 4.970, 95% CI, 1.023~24.140, P = 0.047). No difference was observed in adverse effects between the RT and OP groups (P = 0.154) and in ≥grade 3 adverse effects (P = 0.852).

Conclusion

The study found that surgery was more frequently selected for elderly cervical cancer patients with adenocarcinoma and IB1 stage cancer in the real-world setting. After PSM to balance the biases, it showed that compared with radiotherapy, surgery could improve the OS of elderly early-stage cervical cancer patients and was an independent protective factor of OS in elderly early-stage cervical cancer patients.

Outcomes associated with different surgical approaches to radical hysterectomy: A systematic review and network meta-analysis

OBJECTIVE

To evaluate the efficacy and safety of five different approaches to cervical cancer surgery.

METHODS

We conducted a systematic search for comparative studies on different radical hysterectomy types for cervical cancer in PubMed, Embase, the Cochrane Library, and Web of Science databases. All included observational studies used survival analyses to compare clinical outcomes of patients undergoing different radical hysterectomy types. All studies were assessed by the Newcastle-Ottawa Scale with scores of at least seven points. We extracted the relevant data and conducted a network meta-analysis to compare clinical outcomes among five surgical approaches.

RESULTS

Thirty studies (n = 11 353) were included. Robotic surgery had the lowest blood loss volume and hospitalization duration; open surgery had the shortest operative time. Vaginal assisted laparoscopic surgery was associated with the highest number of resected lymph nodes and lowest rate of perioperative complications. Survival outcomes and tumor recurrence outcomes were similar among the approaches.

CONCLUSION

The current approaches to cervical cancer surgery have comparable efficacies.

Case Report: A rare case of gastric-type adenocarcinoma of stumps of duplicated cervices in a 49-year-old woman: A case with hidden focus confused us a lot

Gastric-type endocervical adenocarcinoma (G-EAC) is a rare special type of cervical mucinous adenocarcinomas, and it is reported the incidence is unrelated to human papilloma virus infection. We report a rare case of G-EAC in stumps of duplicated cervices in a 49-year-old female patient. The woman complained of post-coital bleeding. She had a didelphic uterus with a duplex cervix, and had undergone subtotal hysterectomy 16 years ago. Gynecological examination revealed a normal-appearing right cervix, but the non-dominant side of the left cervix, which was buried and covered by the side wall of the left vagina, was difficult to view. After exposing, the left side cervix presented a mature appearance which was smaller than a normal cervix. Her serum carbohydrate antigen-19-9 levels was 112.59 U/ml. The right cervix's cytology was normal, whereas the left cervix had unusual glandular epithelial cells. HPV testing on both cervical smears was negative. Adenocarcinoma was identified at 3, 6, 12 o'clock at the right cervix in a colposcopy-directed punch biopsy, while no abnormality was found in the biopsy of the left cervix, nor in the curettage of the double cervices. Pelvic magnetic resonance imaging (MRI) revealed two cervical canals, with a 1.9cm×1.6cm mass inside the left cervix, and the left wall of the right cervix may be involved by the tumor of the left cervix. After much deliberation, we considered that the patient had adenocarcinoma of the left cervix stage IB1. Then, the patient underwent radical cervical resection with bilateral salpingo-oophorectomy and bilateral pelvic lymphadenectomy. Her final histopathology indicated G-EAC of the duplicated cervices. After surgery, she received concurrent chemoradiation. Currently, 29 months after the final chemotherapy was administered, the patient remains healthy. Because G-EAC with duplicated cervices is an uncommon cunning tumor with a bad prognosis, early identification and therapy are recommended to enhance the prognosis. The comprehensive evaluation of symptoms and gynecological examination with cervical cytology, colposcopy-directed punch biopsy, endocervical curettage and MRI examine together may assist in determining an accurate preoperative diagnosis.

Minimally invasive radical hysterectomy and the importance of avoiding cancer cell spillage for early-stage cervical cancer: a narrative review

Radical hysterectomy is a standard surgery to treat early-stage uterine cervical cancer. The Laparoscopic Approach to Cervical Cancer (LACC) trial has shown that patients receiving minimally invasive radical hysterectomy have a poorer prognosis than those receiving open radical hysterectomy; however, the reason for this remains unclear. The LACC trial had 2 concerns: the learning curve and the procedural effects. Appropriate management of the learning curve effect, including surgeons' skills, is required to correctly interpret the result of surgical randomized controlled trials. Whether the LACC trial managed the learning curve effect remains controversial, based on the surgeons' inclusion criteria and the distribution of institutions with recurrent cases. An appropriate surgical procedure is also needed, and avoiding intraoperative cancer cell spillage plays an important role during cancer surgery. Cancer cell spillage during minimally invasive surgery to treat cervical cancer is caused by several factors, including 1) exposure of tumor, 2) the use of a uterine manipulator, and 3) direct handling of the uterine cervix. Unfortunately, these issues were not addressed by the LACC trial. We evaluated the results of minimally invasive radical hysterectomy while avoiding cancer cell spillage for early-stage cervical cancer. Our findings show that avoiding cancer cell spillage during minimally invasive radical hysterectomy may ensure an equivalent oncologic outcome, comparable to that of open radical hysterectomy. Therefore, evaluating the importance of avoiding cancer cell spillage during minimally invasive surgery with a better control of the learning curve and procedural effects is needed.

Association of Hospital Surgical Volume With Survival in Early-Stage Cervical Cancer Treated With Radical Hysterectomy

OBJECTIVE

To evaluate the association of number of radical hysterectomies performed per year in each center with disease-free survival and overall survival.

METHODS

We conducted an international, multicenter, retrospective study of patients previously included in the Surveillance in Cervical Cancer collaborative studies. Individuals with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB1-IIA1 cervical cancer who underwent radical hysterectomy and had negative lymph nodes at final histology were included. Patients were treated at referral centers for gynecologic oncology according to updated national and international guidelines. Optimal cutoffs for surgical volume were identified using an unadjusted Cox proportional hazard model, with disease-free survival as the outcome and defined as the value that minimizes the P-value of the split in groups in terms of disease-free survival. Propensity score matching was used to create statistically similar cohorts at baseline.

RESULTS

A total of 2,157 patients were initially included. The two most significant cutoffs for surgical volume were identified at seven and 17 surgical procedures, dividing the entire cohort into low-volume, middle-volume, and high-volume centers. After propensity score matching, 1,238 patients were analyzed-619 (50.0%) in the high-volume group, 523 (42.2%) in the middle-volume group, and 96 (7.8%) in the low-volume group. Patients who underwent surgery in higher-volume institutions had progressively better 5-year disease-free survival than those who underwent surgery in lower-volume centers (92.3% vs 88.9% vs 83.8%, P=.029). No difference was noted in 5-year overall survival (95.9% vs 97.2% vs 95.2%, P=.70). Cox multivariable regression analysis showed that FIGO stage greater than IB1, presence of lymphovascular space invasion, grade greater than 1, tumor diameter greater than 20 mm, minimally invasive surgical approach, nonsquamous cell carcinoma histology, and lower-volume centers represented independent risk factors for recurrence.

CONCLUSION

Surgical volume of centers represented an independent prognostic factor affecting disease-free survival. Increasing number of radical hysterectomies performed in each center every year was associated with improved disease-free survival.

Comparison of long-term bowel symptoms after laparoscopic radical hysterectomy versus abdominal radical hysterectomy in patients with cervical cancer

INTRODUCTION AND HYPOTHESIS

The objective of this study was to compare the long-term bowel symptoms between laparoscopic radical hysterectomy (LRH) and abdominal radical hysterectomy (ARH) in patients with cervical cancer.

METHODS

A total of 207 patients who underwent radical hysterectomy (79 underwent LRH and 128 underwent ARH) at Peking University First Hospital from January 2010 to August 2020 were enrolled and their bowel symptoms were investigated using the Colorectal Anal Distress Inventory-8 (CRADI-8) of the Pelvic Floor Distress Inventory-20. The prevalence and severity of bowel symptoms were compared in the LRH and ARH groups, and multivariate analysis was performed to determine the factors associated with bowel symptoms.

RESULTS

There was no difference in the CRADI-8 scores between the two groups. However, the prevalence of straining at stool was significantly higher in the ARH group than in the LRH group (19.5% versus 1.3%, p<0.001), and the score was significantly higher in the ARH group than in the LRH group too (0.4 versus 0, p<0.001). The prevalence of incomplete defecation was significantly higher in the ARH group than in the LRH group (13.3% versus 3.8%, p=0.029), and the ARH group also had a significantly higher score than the LRH group (0.3 versus 0.1, p=0.028). Multivariate analysis showed that ARH and postoperative interval were independent risk factors for the development of straining at stool.

CONCLUSIONS

Patients with cervical cancer who underwent ARH may be more likely to develop symptoms related to constipation than those who underwent LRH. This finding has to be interpreted with caution owing to the study design.

Spillage and displacement of indocyanine green-stained tissues from uterine cervix to pelvic peritoneum: A proof of concept study for colpotomy approach in minimally invasive surgery

OBJECTIVE

To analyze peritoneal spillage and displacement of indocyanine green (ICG)-stained tissues from uterine cervix to pelvis during intracorporeal/vaginal colpotomy in laparoscopic-assisted hysterectomy.

MATERIALS AND METHODS

Eleven patients undergoing laparoscopic-assisted hysterectomy were included. One patient with an incidental diagnosis of endometrial cancer was excluded. Of the 10 patients, five underwent intracorporeal colpotomy (IC) and five received vaginal colpotomy (VC) during laparoscopic-assisted hysterectomy. Approximately 5 cm of resected round ligament from each patient was stained with ICG and cut to 1.0 × 1.0 cm in size. Four to five fragments of ICG-stained tissues were placed and sutured on the uterine cervix before colpotomy. During and after colpotomy, serial pictures under white and fluorescence light were taken to document peritoneal spillage and displacement of ICG-stained tissues to the pelvic peritoneum.

RESULTS

Peritoneal spillage of ICG occurred in the entire IC group. Displacement of ICG-stained tissues from uterine cervix to pelvic peritoneum were visualized in three (60%) patients undergoing IC. In the five patients who received VC, peritoneal spillage of ICG and displacement of ICG-stained tissue to pelvic peritoneum did not occur. There were no perioperative complications.

CONCLUSIONS

IC in minimally invasive radical hysterectomy should not be performed because peritoneal spillage of ICG and displacement of ICG-stained tissues from uterine cervix to pelvis frequently occurs during IC. Therefore, specific measures to prevent tumor exposure during colpotomy should be implemented in cervical cancer patients.

Overview of laparoscopic surgery for cervical cancer in Japan: Updates after the laparoscopic approach to cervical cancer trial

Laparoscopic radical hysterectomy (LRH) for cervical cancer has been reported to be similar oncologic outcome compared to abdominal radical hysterectomy (ARH) in many retrospective studies. In Japan, LRH has been covered by insurance since April 2018. In 2018, the same year that LRH became covered by insurance, Ramirez et al. at MD Anderson Cancer Center reported the results of a large phase III laparoscopic approach to cervical cancer trial (LACC trial) on the prognosis of open versus laparoscopic/robot-assisted minimally invasive radical hysterectomy. The results showed that minimally invasive approaches were associated with a higher rate of recurrence and death. At this point, it is not clear what is wrong with LRH and why it has a poorer prognosis compared to ARH. In this report, after the LACC report, we would like to review the current status of minimally invasive surgery for cervical cancer and future directions.

Stratification of lymph node metastases as macrometastases, micrometastases, or isolated tumor cells has no clinical implication in patients with cervical cancer: Subgroup analysis of the SCCAN project

BACKGROUND

In cervical cancer, presence of lymph-node macrometastases (MAC) is a major prognostic factor and an indication for adjuvant treatment. However, since clinical impact of micrometastases (MIC) and isolated tumor-cells (ITC) remains controversial, we sought to identify a cut-off value for the metastasis size not associated with negative prognosis.

METHODS

We analyzed data from 967 cervical cancer patients (T1a1L1-T2b) registered in the SCCAN (Surveillance in Cervical CANcer) database, who underwent primary surgical treatment, including sentinel lymph-node (SLN) biopsy with pathological ultrastaging. The size of SLN metastasis was considered a continuous variable and multiple testing was performed for cut-off values of 0.01-1.0 mm. Disease-free survival (DFS) was compared between N0 and subgroups of N1 patients defined by cut-off ranges.

RESULTS

LN metastases were found in 172 (18%) patients, classified as MAC, MIC, and ITC in 79, 54, and 39 patients, respectively. DFS was shorter in patients with MAC (HR 2.20, P = 0.003) and MIC (HR 2.87, P < 0.001), while not differing between MAC/MIC (P = 0.484). DFS in the ITC subgroup was neither different from N0 (P = 0.127) nor from MIC/MAC subgroups (P = 0.449). Cut-off analysis revealed significantly shorter DFS compared to N0 in all subgroups with metastases ≥0.4 mm (HR 2.311, P = 0.04). The significance of metastases <0.4 mm could not be assessed due to limited statistical power (<80%). We did not identify any cut-off for the size of metastasis with significantly better prognosis than the rest of N1 group.

CONCLUSIONS

In cervical cancer patients, the presence of LN metastases ≥0.4 mm was associated with a significant negative impact on DFS and no cut-off value for the size of metastasis with better prognosis than N1 was found. Traditional metastasis stratification based on size has no clinical implication.
