Meta-Analysis Review
PURPOSE
To evaluate the impact of the extension of the radiotherapy field cranially toward para-aortic lymph nodes (EF-RT) in advanced cervical cancer.
MATERIALS AND METHODS
A systematic search of databases (PubMed, CENTRAL, Clinical Trials) was performed and included studies that were published between 1960 and November 2015 without language restrictions. All randomized clinical trials (RCTs) were analyzed further. All patients must have undergone pelvic radiotherapy and the same systemic therapy in both arms. The primary endpoints were locoregional failure, incidence of distant metastasis, para-aortic failure, and cancer related death. The Mantel-Haenszel method was used in the meta-analysis. The risk of bias analysis was determined using the 7-domain method per the Cochrane Handbook for Systematic Reviews of Interventions V5.1.0. A review of the treatment technique and toxicity was also performed.
RESULTS
A total of 1309 studies were evaluated, 4 RCTs of which met the inclusion criteria; 506 patients were allocated to standard pelvic irradiation, and 494 underwent EF-RT. The risk of bias was considered to be low in nearly 80% of the domains. EF-RT significantly reduced the rate of para-aortic failure (HR 0.35, 95% CI 0.19-0.64; p<0.01) and the incidence of other distant metastases (HR 0.69, 95% CI 0.50-0.96; p=0.03). Locoregional failure and cancer-related death were not significantly altered (OR 1.06 [0.80-1.42]; p=0.67, and 0.68 [0.45-1.01]; p=0.06, respectively). The radiotherapy technique was conventional in 3 studies and conformational in 1 study. In total, 10 treatment-related deaths occurred-4 in pelvic radiation and 6 in EF-RT (OR 2.12 [0.71-6.27]; p=0.18).
CONCLUSIONS
EF-RT that targets the para-aortic lymphatic chain reduces distant metastatic events, but its impact on survival is unknown. Future studies should examine the value of EF-RT using modern radiation techniques.

Review
BACKGROUND
Retroperitoneal nerve sheath tumors present a surgical challenge. Despite potential advantages, robotic surgery for these tumors has been limited. Identifying and sparing functional nerve fascicles during resection can be difficult, increasing the risk of neurological morbidity.
OBJECTIVE
To review the literature regarding robotic resection of retroperitoneal nerve sheath tumors and retrospectively analyze our experience with robotic resection of these tumors using a manual electromyographic probe to identify and preserve functional nerve fascicles.
METHODS
We retrospectively analyzed the clinical courses of 3 patients with retroperitoneal tumors treated at the National Institutes of Health by a multidisciplinary team using the da Vinci Xi system. Parent motor nerve fascicles were identified intraoperatively with a bipolar neurostimulation probe inserted through a manual port, permitting tumor resection with motor fascicle preservation.
RESULTS
Two patients with neurofibromatosis type 1 underwent surgery for retroperitoneal neurofibromas located within the iliopsoas muscle, and 1 patient underwent surgery for a pelvic sporadic schwannoma. All tumors were successfully resected, with no complications or postoperative neurological deficits. Preoperative symptoms were improved or resolved in all patients.
CONCLUSION
Resection of retroperitoneal nerve sheath tumors confers an excellent prognosis, although their deep location and proximity to vital structures present unique challenges. Robotic surgery with intraoperative neurostimulation mapping is safe and effective for marginal resection of histologically benign or atypical retroperitoneal nerve sheath tumors, providing excellent visibility, increased dexterity and precision, and reduced risk of neurological morbidity.

Review
DESCRIPTION
The American College of Physicians (ACP) developed this guideline to present the evidence and provide clinical recommendations on the utility of screening pelvic examination for the detection of pathology in asymptomatic, nonpregnant, adult women.
METHODS
This guideline is based on a systematic review of the published literature in the English language from 1946 through January 2014 identified using MEDLINE and hand-searching. Evaluated outcomes include morbidity; mortality; and harms, including overdiagnosis, overtreatment, diagnostic procedure-related harms, fear, anxiety, embarrassment, pain, and discomfort. The target audience for this guideline includes all clinicians, and the target patient population includes asymptomatic, nonpregnant, adult women. This guideline grades the evidence and recommendations using the ACP's clinical practice guidelines grading system.
RECOMMENDATION
ACP recommends against performing screening pelvic examination in asymptomatic, nonpregnant, adult women (strong recommendation, moderate-quality evidence).

Review
Correlations between bone marrow radiation dose and hematologic toxicity in locally advanced cervical cancer patients receiving chemoradiation with cisplatin: a systematic review.
Patients with locally advanced cervical cancer (LACC) treated with chemoradiation often experience hematologic toxicity (HT), as chemoradiation can induce bone marrow (BM) suppression. Studies on the relationship between BM dosimetric parameters and clinically significant HT might provide relevant indices for developing BM sparing (BMS) radiotherapy techniques. This systematic review studied the relationship between BM dose and HT in patients with LACC treated with primary cisplatin-based chemoradiation. A systematic search was conducted in Embase, Medline, and Web of Science. Eligibility criteria were treatment of LACC-patients with cisplatin-based chemoradiation and report of HT or complete blood cell count (CBC). The search identified 1346 papers, which were screened on title and abstract before two reviewers independently evaluated the full-text. 17 articles were included and scored according to a selection of the TRIPOD criteria. The mean TRIPOD score was 12.1 out of 29. Fourteen studies defining BM as the whole pelvic bone contour (PB) detected significant associations with V10 (3/14), V20 (6/14), and V40 (4/11). Recommended cut-off values were V10 > 95-75%, V20 > 80-65%, and V40 > 37-28%. The studies using lower density marrow spaces (PBM) or active bone marrow (ABM) as a proxy for BM only found limited associations with HT. Our study was the first literature review providing an overview of articles evaluating the correlation between BM and HT for patients with LACC undergoing cisplatin-based chemoradiation. There is a scarcity of studies independently validating developed prediction models between BM dose and HT. Future studies may use PB contouring to develop normal tissue complication probability models.

Meta-Analysis
PURPOSE
A broad range of therapeutic options exists for symptomatic postoperative lymphoceles. However, no consensus exists on what is the optimal therapy. In this study, we aimed to compare the efficacy of currently available radiologic interventions in terms of number of successful interventions, number of recurrences, and number of complications.
METHODS
A systematic review was conducted with a pre-defined search strategy for PubMed, EMBASE, and Cochrane databases from inception until September 2019. Quality assessment was performed using the 'Risk Of Bias In Non-randomized Studies - of Interventions' tool. Statistical heterogeneity was assessed using the I and χ test and a meta-analysis was considered for studies reporting on multiple interventions.
RESULTS
37 eligible studies including 732 lymphoceles were identified. Proportions of successful interventions for percutaneous fine needle aspiration, percutaneous catheter drainage, percutaneous catheter drainage with delayed or instantaneous addition of sclerotherapy, and embolization were as follows: 0.341 (95% confidence interval [CI]: 0.185-0.542), 0.612 (95% CI: 0.490-0.722), 0.890 (95% CI: 0.781-0.948), 0.872 (95% CI: 0.710-0.949), 0.922 (95% CI: 0.731-0.981). Random-effects meta-analysis of seven studies revealed a pooled relative risk for percutaneous catheter drainage with delayed addition of sclerotherapy of 1.57 (95% CI: 1.17-2.10) when compared to percutaneous catheter drainage alone. The risk of bias in this study was severe.
CONCLUSIONS
This systematic review demonstrates that the success rates of percutaneous catheter drainage with sclerotherapy are more favorable when compared to percutaneous catheter drainage alone in the treatment of postoperative pelvic lymphoceles. Overall, percutaneous catheter drainage with delayed addition of sclerotherapy, and embolization showed the best outcomes.

Meta-Analysis Review
BACKGROUND
This is an updated version of the original Cochrane review published in Issue 1, 2010. 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, this policy has been challenged by the findings from recent studies.
OBJECTIVES
To assess the effects of retroperitoneal drainage versus no drainage after pelvic lymphadenectomy on lymphocyst formation and related morbidities in gynaecological cancer patients.
SEARCH METHODS
We searched the Cochrane Gynaecological Cancer Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL 2013, Issue 12) in The Cochrane Library, electronic databases MEDLINE (Nov Week 3, 2013), EMBASE (2014, week 1), and the citation lists of relevant publications. The latest searches were performed on 10 January 2014.
SELECTION CRITERIA
Randomised controlled trials (RCTs) that compared the effect of retroperitoneal drainage versus no drainage after pelvic lymphadenectomy in gynaecological cancer patients. 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, no new studies have been identified for inclusion. The review included four studies with 571 participants. Considering the 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 (two studies, 204 patients; RR 0.76, 95% CI 0.04 to 13.35). When the pelvic peritoneum was left open, the rates of overall lymphocyst formation (one study, 110 patients; RR 2.29, 95% CI 1.38 to 3.79) and symptomatic lymphocyst formation (one study, 137 patients; 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 (one study, 232 patients; RR 1.48, 95% CI 0.89 to 2.45). However, there was a trend toward increased risk of symptomatic lymphocyst formation in the group with drains (one study, 232 patients; RR 7.12, 95% CI 0.89 to 56.97). The included trials were of low to moderate risk of bias.
AUTHORS' CONCLUSIONS
Placement of retroperitoneal tube drains has no benefit in prevention of lymphocyst formation after pelvic lymphadenectomy in patients 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.

Meta-Analysis Review
Endometrial cancer is the most frequent tumor in the female reproductive system, while the sentinel lymph node (SLN) mapping for diagnostic efficacy of endometrial cancer is still controversial. This meta-analysis was conducted to evaluate the diagnostic value of SLN in the assessment of lymph nodal involvement in endometrial cancer. Forty-four studies including 2,236 cases were identified. The pooled overall detection rate was 83% (95% CI: 80-86%). The pooled sensitivity was 91% (95% CI: 87-95%). The bilateral pelvic node detection rate was 56% (95% CI: 48-64%). Use of indocyanine green (ICG) increased the overall detection rate to 93% (95% CI: 89-96%) and robotic-assisted surgery also increased the overall detection rate to 86% (95% CI: 79-93%). In summary, our meta-analysis provides strong evidence that sentinel node mapping is an accurate and feasible method that performs well diagnostically for the assessment of lymph nodal involvement in endometrial cancer. Cervical injection, robot-assisted surgery, as well as using ICG, optimized the sensitivity and detection rate of the technique. Sentinel lymph mapping may potentially leading to a greater utilization by gynecologic surgeons in the future.

Meta-Analysis Review
INTRODUCTION
To date, bilateral pelvic lymph node dissection (PLND) represents the most accurate and reliable staging procedure for the detection of lymph node invasion in prostate cancer and bladder cancer. However, the procedure is not devoid of complications. In this field, Indocyanine green fluorescence-guided sentinel lymph node (SLN) identification is an emerging and promising technique, as accurate staging of urologic cancer could be enhanced by a thorough evaluation of the sentinel lymph nodes. Aim of the present review is to analyze available evidence and perform a metanalysis on ICG-guided SLN detection for urologic malignancies.
EVIDENCE ACQUISITION
A systematic review to assess the clinical value of Indocyanine green for the identification of sentinel lymphatic drainage for bladder, prostate, kidney and penile cancers was undertaken, with a meta-analysis to generate pooled detection rate concerning patients (clinical sensitivity) and nodes basin (technical sensitivity) separately. Studies reporting on the use of Indocyanine green for the detection of SLNs from the bladder, prostate and penile cancers were included.
EVIDENCE SYNTHESIS
A total of 10 clinical trials were included. Using the fixed effects model and the random effects model, the pooled patient detection rates and their 95% confidence intervals (95% CI) were 0.88 (0.82-0.92) and 0.92 (0.84-0.96), respectively. The pooled nodes detection rates were 0.71 (95% CI: 0.68-0.74) using the fixed effect model and 0.75 (95% CI: 0.56-0.87) using the random effect model. Significant heterogeneities existed among studies for patients and for nodes (I2=0.66, P<0.001 and I2=0.96, P<0.001, respectively). Significant publication bias was found in patient detection rate (P<0.001) and in nodes detection rate (P<0.001).
CONCLUSIONS
SLN mapping in bladder and prostate cancer is a method with a high detection rate, although its specificity to predict LN invasion remains poor. Large, well-constructed trails are needed to assess the impact of ICG-fluorescence guided SLN dissection on uro-oncologic surgery.

Meta-Analysis
BACKGROUND The use of adjuvant therapy for high-risk endometrial cancer patients (HREC) in International Federation of Gynecology and Obstetrics (FIGO) stage I-III remains debatable. This network meta-analysis was conducted to compare and rank adjuvant therapies based on efficacies and toxicities to facilitate clinical decision-making and further research. MATERIAL AND METHODS We searched 3 databases - PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials - from inception to December 9, 2019. Only randomized controlled trials that compared any of these adjuvant therapies (pelvic radiotherapy, vaginal brachytherapy, chemotherapy, and chemoradiotherapy) with each other or surgery alone were included. The network meta-analysis was performed in a frequentist framework using Stata software 15.0. RESULTS Fourteen RCTs with 5872 participants were eligible. No significant difference between treatments was observed in 5-year overall survival (OS) or distant metastasis. Compared with surgery alone, adjuvant pelvic radiotherapy plus chemotherapy (pelvic RT-CT) prolonged 5-year progression-free survival (PFS) and pelvic radiotherapy (pelvic RT) (RR=0.61, 95% CI 0.39-0.96; RR=0.779, 95% CI 0.63-0.95). Compared with surgery alone, pelvic RT, the combination of pelvic RT and vaginal brachytherapy (pelvic RT-VBT), chemotherapy (CT), and pelvic RT-CT led to fewer local recurrences (RR=0.33, 95% CI 0.21-0.50; RR=0.15, 95% CI 0.03-0.74; RR=0.39, 95% CI 0.21-0.73; RR=0.17, 95% CI 0.06-0.46). Adjuvant CT was found to result in more grade III/IV late toxicities than surgery alone (RR=11.8, 95% CI 1.02-137.14). Pelvic RT-CT ranked first for OS, PFS, distant metastasis, and local recurrence. CONCLUSIONS Pelvic RT-CT is superior to other treatments for PFS and local recurrence rate, and associated related toxicities are tolerable, suggesting it may be an ideal adjuvant therapy for HREC patients.

Meta-Analysis Review
Previous studies reported inconsistent findings about the relationship between pretreatment thrombocytosis and survival in patients with cervical cancer. This study aimed to evaluate the prognostic significance of thrombocytosis in cervical cancer. We searched databases to identify relevant articles. Pooled hazard ratios (HRs), odds ratios (ORs), and 95% confidence intervals (CIs) were calculated. Fourteen studies including 3,394 patients were eligible for the meta-analysis. Overall, an elevated platelet count was significantly associated with inferior overall survival (OS, hazard ratio [HR]: 1.66, 95% confidence interval [CI]: 1.42-1.95, P < 0.001) and recurrence-free survival (RFS, HR: 1.67, 95% CI: 1.15-2.42, P = 0.007) but not progression-free survival (PFS, HR: 1.21, 95% CI: 0.89-1.64; P = 0.235). The results were similar for low stage patients treated with surgery alone. Moreover, a pretreatment thrombocytosis status was significantly associated with higher clinical stage (odd ratio [OR]: 2.39, 95% CI: 1.68-3.38, P < 0.001), positive pelvic node status (OR: 1.58, 95% CI: 1.01- 2.45, P = 0.044) and larger tumor size (OR: 2.32, 95% CI: 1.39-3.87, P = 0.001). Pretreatment thrombocytosis is an independent prognosis predictor in cervical cancer patients. It may be used as a readily available biomarker to refine clinical outcome prediction for cervical cancer patients.
