Review
The standard treatment approach in locally advanced cervical cancer (LACC) is exclusive concurrent chemoradiation therapy (RTCT). The risk of local residual disease after six months from RTCT is about 20-30%. It is directly related to relapse risk and poor survival, such as in patients with recurrent cervical cancer. This systematic review aims to describe studies investigating salvage surgery's role in persistent/recurrent disease in LACC patients who underwent definitive RTCT. Studies were eligible for inclusion when patients had LACC with radiologically suspected or histologically confirmed residual disease after definitive RTCT, diagnosed with post-treatment radiological workup or biopsy. Information on complications after salvage surgery and survival outcomes had to be reported. The methodological quality of the articles was independently assessed by two researchers with the Newcastle-Ottawa scale. Following the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, we systematically searched the PubMed, Scopus, Cochrane, Medline, and Medscape databases in May 2022. We applied no language or geographical restrictions but considered only English studies. We included studies containing data about postoperative complications and survival outcomes. Eleven studies fulfilled the inclusion criteria and all were retrospective observational studies. A total of 601 patients were analyzed concerning the salvage surgery in LACC patients for persistent/recurrent disease after RTCT treatment. Overall, 369 (61.4%) and 232 (38.6%) patients underwent a salvage hysterectomy (extrafascial or radical) and pelvic exenteration (anterior, posterior, or total), respectively. Four hundred and thirty-nine (73%) patients had histologically confirmed the residual disease in the salvage surgical specimen, and 109 patients had positive margins (overall range 0-43% of the patients). The risk of severe (grade ≥ 3) postoperative complications after salvage surgery is 29.8% (range 5-57.5%). After a median follow-up of 38 months, the overall RR was about 32% with an overall death rate of 40% after hysterectomy or pelvic exenteration with or without lymphadenectomy. There is heterogeneity between the studies both in their design and results, therefore the effect of salvage surgery on survival and recurrence cannot be adequately estimated. Future homogeneous studies with an appropriately selected population are needed to analyze the safety and efficacy of salvage hysterectomy or pelvic exenteration in patients with residual tumors after definitive RTCT.

Meta-Analysis Review
: Pelvic lymphadenectomy has been associated with radical hysterectomy for the treatment of early Cervical Cancer (ECC) since 1905. However, some complications are related to this technique, such as lymphedema and nerve damage. In addition, its clinical role is controversial. For this reason, the sentinel lymph node (SLN) has found increasing use in clinical practice over time. Oncologic safety, however, is debated, and there is no clear evidence in the literature regarding this. Therefore, our meta-analysis aims to schematically analyze the current scientific evidence to investigate the non-inferiority of SLN versus PLND regarding oncologic outcomes. : Following the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, we systematically searched the PubMed and Scopus databases in June 2022 since their early first publications. We made no restrictions on the country. We considered only studies entirely published in English. We included studies containing Disease-Free Survival (DFS), Overall Survival (OS), Recurrence Rate (RR), and site of recurrence data. We used comparative studies for meta-analysis. We registered this meta-analysis to the PROSPERO site for meta-analysis with protocol number CRD42022316650. : Twelve studies fulfilled inclusion criteria. The four comparative studies were enrolled in meta-analysis. Patients were analyzed concerning Sentinel Lymph Node Biopsy (SLN) and compared with Bilateral Pelvic Systematic Lymphadenectomy (PLND) in early-stage Cervical Cancer (ECC). Meta-analysis highlighted no differences in oncological safety between these two techniques, both in DFS and OS. Moreover, most of the sites of recurrences in the SLN group seemed not to be correlated with missed lymphadenectomy. : Data in the literature do not seem to show clear oncologic inferiority of SLN over PLND. On the contrary, the higher detection rate of positive lymph nodes and the predominance of no lymph node recurrences give hope that this technique may equal PLND in oncologic terms, improving its morbidity profile.

Meta-Analysis Review
Protective operative techniques in radical hysterectomy in early cervical carcinoma and their influence on disease-free and overall survival: a systematic review and meta-analysis of risk groups.
PURPOSE
Radical hysterectomy with pelvic lymphadenectomy presents the standard treatment for early cervical cancer. Recently, studies have shown a superior oncological outcome for open versus minimal invasive surgery, however, the reasons remain to be speculated. This meta-analysis evaluates the outcomes of robotic and laparoscopic hysterectomy compared to open hysterectomy. Risk groups including the use of uterine manipulators or colpotomy were created.
METHODS
Ovid-Medline and Embase databases were systematically searched in June 2020. No limitation in date of publication or country was made. Subgroup analyses were performed regarding the surgical approach and the endpoints OS and DFS.
RESULTS
30 studies fulfilled the inclusion criteria. Five prospective, randomized-control trials were included. Patients were analyzed concerning the surgical approach [open surgery (AH), laparoscopic surgery (LH), robotic surgery (RH)]. Additionally, three subgroups were created from the LH group: the LH high-risk group (manipulator), intermediate-risk group (no manipulator, intracorporal colpotomy) and LH low-risk group (no manipulator, vaginal colpotomy). Regarding OS, the meta-analysis showed inferiority of LH in total over AH (0.97 [0.96; 0.98]). The OS was significantly higher in LH low risk (0.96 [0.94; 0.98) compared to LH intermediate risk (0.93 [0.91; 0.94]). OS rates were comparable in AH and LH Low-risk group. DFS was higher in the AH group compared to the LH group in general (0.92 [95%-CI 0.88; 0.95] vs. 0.87 [0.82; 0.91]), whereas the application of protective measures (no uterine manipulator in combination with vaginal colpotomy) was associated with increased DFS in laparoscopy (0.91 [0.91; 0.95]).
CONCLUSION
DFS and OS in laparoscopy appear to be depending on surgical technique. Protective operating techniques in laparoscopy result in improved minimal invasive survival.

Meta-Analysis Review
BACKGROUND
This is an updated version of an original Cochrane review published in Issue 6, 2014. Pelvic lymphadenectomy is associated with significant complications including lymphocyst formation and related morbidities. Retroperitoneal drainage using suction drains has been recommended as a method to prevent such complications. However, findings from recent studies have challenged this policy.
OBJECTIVES
To assess the effects of retroperitoneal drainage versus no drainage after pelvic lymphadenectomy on lymphocyst formation and related morbidities in women with gynaecological cancer.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3, 2017) in the Cochrane Library, electronic databases MEDLINE (1946 to March Week 2, 2017), Embase (1980 to 2017 week 12), and the citation lists of relevant publications. We also searched the trial registries for ongoing trials on 20 May 2017.
SELECTION CRITERIA
Randomised controlled trials (RCTs) that compared the effect of retroperitoneal drainage versus no drainage after pelvic lymphadenectomy in women with gynaecological cancer. Retroperitoneal drainage was defined as placement of passive or active suction drains in pelvic retroperitoneal spaces. No drainage was defined as no placement of passive or active suction drains in pelvic retroperitoneal spaces.
DATA COLLECTION AND ANALYSIS
We assessed studies using methodological quality criteria. For dichotomous data, we calculated risk ratios (RRs) and 95% confidence intervals (CIs). We examined continuous data using mean difference (MD) and 95% CI.
MAIN RESULTS
Since the last version of this review, we have identified no new studies for inclusion. The review included four studies with 571 women. Regarding short-term outcomes (within four weeks after surgery), retroperitoneal drainage was associated with a comparable rate of overall lymphocyst formation when all methods of pelvic peritoneum management were considered together (2 studies; 204 women; RR 0.76, 95% CI 0.04 to 13.35; moderate-quality evidence). When the pelvic peritoneum was left open, the rates of overall lymphocyst formation (1 study; 110 women; RR 2.29, 95% CI 1.38 to 3.79) and symptomatic lymphocyst formation (2 studies; 237 women; RR 3.25, 95% CI 1.26 to 8.37) were higher in the drained group. At 12 months after surgery, the rates of overall lymphocyst formation were comparable between the groups (1 study; 232 women; RR 1.48, 95% CI 0.89 to 2.45; high-quality evidence). However, there was a trend toward increased risk of symptomatic lymphocyst formation in the group with drains (1 study; 232 women; RR 7.12, 95% CI 0.89 to 56.97; low-quality evidence).
AUTHORS' CONCLUSIONS
Placement of retroperitoneal tube drains has no benefit in the prevention of lymphocyst formation after pelvic lymphadenectomy in women with gynaecological malignancies. When the pelvic peritoneum is left open, the tube drain placement is associated with a higher risk of short- and long-term symptomatic lymphocyst formation. We found the quality of evidence using the GRADE approach to be moderate to high for most outcomes, except for symptomatic lymphocyst formation at 12 months after surgery, and unclear or low risk of bias.

Review
Cervical cancer is the second most common cancer in women. Neoadjuvant chemotherapy for patients with locally advanced cervix cancer has comparable benefits to concurrent chemoradiotherapy (CCRT), but with fewer side effects. This systematic review aims to provide a comprehensive summary of the benefits of neoadjuvant chemotherapy for the management of locally advanced cervix cancer from stage IB2 (tumor >4.0 cm) to IIIB (tumor extending to the pelvic wall and/or hydronephrosis). Our primary objective was to assess benefits in terms of survival. The data source included the USA national library of medicine, Medline search, and the National Cancer Institute PDQ Clinical Protocols. Inclusion criteria for consideration in the current systematic review included studies published between January 1997 and December 2012. In terms of histology, they had to be focused on squamous cell carcinoma, adenosquamous carcinoma, and/or adenocarcinoma. Patients should be either chemotherapy naïve or cervix cancer chemotherapy naïve, and have a performance status ≤2. The search in the above-mentioned scientific websites led to identify 49 publications, 19 of which were excluded, as they did not meet the inclusion criteria of this systematic review. Therefore only 30 studies were deemed eligible. Data was collected from 1760 patients enrolled in the current systematic review study. The mean age was 45.2 years. The mean tumor size was 4.7 cm. The most commonly used chemotherapies were cisplatin doublets. Paclitaxel was the most commonly used chemotherapeutic agent in the doublets. The mean chemotherapy cycles were 2.7. After chemotherapy, patients underwent surgery after a mean time of 2.5 weeks. The standard operation was radical hysterectomy with pelvic lymphadenectomy. Chemotherapy achieved an objective response rate of 84%. The 5-year progression-free survival and overall survival were 61.9% and 72.8% respectively. The treatment protocol was associated with a mild early toxicity profile. Leucopenia and neutropenia were the most common side effects. Late toxicity was also generally mild and mainly associated with bladder dysfunction and vaginal dehiscence. The quality of the studies was assessed using the Newcastle-Ottawa quality assessment scale. Neoadjuvant chemotherapy achieved comparable survival results to CCRT, and was associated with less toxicity.

Meta-Analysis Review
Perioperative morbidity of different operative approaches in early cervical carcinoma: a systematic review and meta-analysis comparing minimally invasive versus open radical hysterectomy.
PURPOSE
Radical hysterectomy and pelvic lymphadenectomy is the standard treatment for early cervical cancer. Studies have shown superior oncological outcome for open versus minimal invasive surgery, but peri- and postoperative complication rates were shown vice versa. This meta-analysis evaluates the peri- and postoperative morbidities and complications of robotic and laparoscopic radical hysterectomy compared to open surgery.
METHODS
Embase and Ovid-Medline databases were systematically searched in June 2020 for studies comparing robotic, laparoscopic and open radical hysterectomy. There was no limitation in publication year. Inclusion criteria were set analogue to the LACC trial. Subgroup analyses were performed regarding the operative technique, the study design and the date of publication for the endpoints intra- and postoperative morbidity, estimated blood loss, hospital stay and operation time.
RESULTS
27 studies fulfilled the inclusion criteria. Five prospective, randomized-control trials were included. Meta-analysis showed no significant difference between robotic radical hysterectomy (RH) and laparoscopic hysterectomy (LH) concerning intra- and perioperative complications. Operation time was longer in both RH (mean difference 44.79 min [95% CI 38.16; 51.42]), and LH (mean difference 20.96 min; [95% CI - 1.30; 43.22]) than in open hysterectomy (AH) but did not lead to a rise of intra- and postoperative complications. Intraoperative morbidity was lower in LH than in AH (RR 0.90 [0.80; 1.02]) as well as in RH compared to AH (0.54 [0.33; 0.88]). Intraoperative morbidity showed no difference between LH and RH (RR 1.29 [0.23; 7.29]). Postoperative morbidity was not different in any approach. Estimated blood loss was lower in both LH (mean difference - 114.34 [- 122.97; - 105.71]) and RH (mean difference - 287.14 [- 392.99; - 181.28]) compared to AH, respectively. Duration of hospital stay was shorter for LH (mean difference - 3.06 [- 3.28; - 2.83]) and RH (mean difference - 3.77 [- 5.10; - 2.44]) compared to AH.
CONCLUSION
Minimally invasive radical hysterectomy appears to be associated with reduced intraoperative morbidity and blood loss and improved reconvalescence after surgery. Besides oncological and surgical factors these results should be considered when counseling patients for radical hysterectomy and underscore the need for new randomized trials.

Review
In early-stage cervical cancer, ovarian metastasis is relatively rare, and ovarian transposition is often performed during surgery. Although rare, the diagnosis and surgical approach for recurrence at transposed ovaries are challenging. This study focused on the diagnosis and surgical management of transposed ovarian recurrence in cervical cancer patients. A 45-year-old premenopausal woman underwent radical hysterectomy, bilateral salpingectomy, and pelvic lymphadenectomy following postoperative concurrent chemoradiotherapy for stage IB1 cervical cancer. During the initial surgery, the ovary was transposed to the paracolic gutter, and no postoperative complications were observed. Ovarian recurrence was diagnosed using positron emission tomography-computed tomography, and a laparoscopic bilateral oophorectomy was performed. A systematic review identified nine women with transposed ovarian recurrence with no other metastases of cervical cancer, and no studies have discussed the optimal surveillance of transposed ovaries. Of those (n = 9), four women had died of the disease within 2 years of the second surgery, and the prognosis of transposed ovarian cervical cancer seemed poor. Nevertheless, three women underwent laparoscopic oophorectomies, none of whom experienced recurrence after the second surgery. Few studies have examined the surgical management of transposed ovarian recurrence. The optimal surgical approach for transposed ovarian recurrence of cervical cancer requires further investigation.

Meta-Analysis
A comparative analysis of perioperative complications and biochemical recurrence between standard and extended pelvic lymph node dissection in prostate cancer patients undergoing radical prostatectomy: a systematic review and meta-analysis.
INTRODUCTION
Pelvic lymph node dissection (PLND) is commonly performed during radical prostatectomy (RP) for prostate cancer staging. This study aimed to comprehensively analyze existing evidence compare perioperative complications associated with standard (sPLND) versus extended PLND templates (ePLND) in RP patients.
METHODS
A meta-analysis of prospective studies on PLND complications was conducted. Systematic searches were performed on Web of Science, Pubmed, Embase, and the Cochrane Library until May 2023. Risk ratios (RRs) were estimated using random-effects models in the meta-analysis. The statistical analysis of the data was carried out using Review Manager software.
RESULTS
Nine studies, including three randomized clinical trial and six prospective studies, with a total of 4962 patients were analyzed. The meta-analysis revealed that patients undergoing ePLND had a higher risk of partial perioperative complications, such as lymphedema ( I2 =28%; RR 0.05; 95% CI: 0.01-0.27; P <0.001) and urinary retention ( I2 =0%; RR 0.30; 95% CI: 0.09-0.94; P =0.04) compared to those undergoing sPLND. However, there were no significant difference was observed in pelvic hematoma ( I2 =0%; RR 1.65; 95% CI: 0.44-6.17; P =0.46), thromboembolic ( I2 =57%; RR 0.91; 95% CI: 0.35-2.38; P =0.85), ureteral injury ( I2 =33%; RR 0.28; 95% CI: 0.05-1.52; P =0.14), intraoperative bowel injury ( I2 =0%; RR 0.87; 95% CI: 0.14-5.27; P =0.88), and lymphocele ( I2 =0%; RR 1.58; 95% CI: 0.54-4.60; P =0.40) between sPLND and ePLND. Additionally, no significant difference was observed in overall perioperative complications ( I2 =85%; RR 0.68; 95% CI: 0.40-1.16; P =0.16). Furthermore, ePLND did not significantly reduce biochemical recurrence ( I2 =68%; RR 0.59; 95% CI: 0.28-1.24; P =0.16) of prostate cancer.
CONCLUSION
This analysis found no significant differences in overall perioperative complications or biochemical recurrence between sPLND and ePLND, but ePLND may offer enhanced diagnostic advantages by increasing the detection rate of lymph node metastasis.

Archivos Espanoles de Urologia Oct 2019ICG navigation in cancer surgery may help during pelvic lymphadenectomy.
OBJECTIVE
ICG navigation in cancer surgery may help during pelvic lymphadenectomy.
METHODS
We performed a systematic review combining the terms: bladder cancer or radical cystectomy and ICG, and prostate cancer or radical prostatectomy and ICG. We used the PRISMA guidelines recommendations. We describe the populations studied in each work, the pathological results, as well as the parameters specificity, sensitivity and predictive values.
RESULTS
In muscle-invasive bladder cancer, 4 case series analyzed the performance of lymphography with ICG. The most accepted injection method is under endoscopic vision. Several punctures are done in the submucosa and the detrusor surrounding the scar. Sentinel nodes were found in up to 92% of patients with a technique sensitivity to find metastases of 88% in the series with largest casuistry. In prostate cancer, we collected data from 11 case series. Nine of them apply transrectal or transperineal dilution immediately before surgery. Sensitivity in the detection of all adenopathies ranged between 44% and 100%. The sensitivity of the technique to know the lymph node stage ranges between 67% and 100%.
CONCLUSIONS
There is little experience of ICG-guided lymph node dissedction in bladder tumors. Endoscopic fluorophore injection allows us to find the nodes that drain the infiltrated area. However, the use of this technique is not widespread. In prostate cancer, it is a reproducible and efficient technique for staging patients with prostate cancer.
