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.

BACKGROUND
Approximately 4380 cases of cervical carcinoma were diagnosed in Germany in 2016. In women who had not participated in early detection programs, cervical carcinoma was usually already in an advanced stage at the time of diagnosis. Certified structures for care in conformity with the existing guidelines are available.
METHODS
The new German clinical practice guideline was revised with the participation of 50 medical societies under the expert guidance of the Guideline Program in Oncology, which includes the German Association of the Scientific Medical Societies (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, AWMF). A systematic literature review was conducted. Systematic reviews, meta-analyses, and randomized controlled trials (RCTs) were considered.
RESULTS
The histologic tumor stage and lymph-node stage are essential determinants of the treatment strategy. The main innovation regarding surgical treatment is the revival of open hysterectomy (overall survival [minimally invasive vs open hysterectomy]: 94.04% vs 99.4%; hazard ratio [HR]: 6.00; 95% confidence interval [1.77; 20.30]). In addition, for tumors measuring 2 cm or less, sentinel node biopsy is recommended rather than radical pelvic lymphadenectomy. MRI-guided brachytherapy is an oblig atory component of radiochemotherapy (overall survival [radiochemotherapy with vs without brachytherapy]: 58.2% vs 46.2%, p<0.001). The standard palliative treatment consists of bevacizumab combined with a platinum-containing agent (overall survival: HR: 0.77 [0.62; 0.95]; p = 0.007).
CONCLUSION
Despite the introduction of new treatments, the outcome of patients with advanced cervical carcinoma has not much improved. In the surgical treatment of cervical carcinoma, the open approach is now favored. The sentinel node biopsy technique has become well established for the surgical staging of small tumors. Controlled trials are needed so that the outcome of women with cervical carcinoma, particularly in its advanced and metastatic stages, can be improved.

Meta-Analysis Review
BACKGROUND
Uterine fibroids (also known as leiomyomas) are the most common benign pelvic tumours among women. They may be asymptomatic, or may be associated with pelvic symptoms such as bleeding and pain. Medical treatment of this condition is limited and gonadotropin-releasing hormone (GnRH) analogues are the most effective agents. Long-term treatment with such agents, however, is restricted due to their adverse effects. The addition of other medications during treatment with GnRH analogues, a strategy known as add-back therapy, may limit these side effects. There is concern, however, that add-back therapy may also limit the efficacy of the GnRH analogues and that it may not be able to completely prevent their adverse effects.
OBJECTIVES
To assess the short-term (within 12 months) effectiveness and safety of add-back therapy for women using GnRH analogues for uterine fibroids associated with excessive uterine bleeding, pelvic pain, or urinary symptoms.
SEARCH METHODS
We searched electronic databases including the Cochrane Menstrual Disorders and Subfertility Group (MDSG) Specialised Register, CENTRAL, MEDLINE, PubMed, EMBASE, LILACS, CINAHL, PsycINFO; and electronic registries of ongoing trials including ClinicalTrials.gov, Current Controlled Trials, World Health Organization (WHO) International Clinical Trials Registry Platform. All searches were from database inception to 16 June 2014.
SELECTION CRITERIA
Randomized controlled trials (RCTs) that included women with uterine fibroids experiencing irregular or intense uterine bleeding, cyclic or non-cyclic pelvic pain, or urinary symptoms, and that compared treatment with a GnRH analogue plus add-back therapy versus a GnRH analogue alone or combined with placebo were eligible for inclusion.
DATA COLLECTION AND ANALYSIS
Two authors independently reviewed the identified titles and abstracts for potentially eligible records. Two review authors reviewed eligible studies and independently extracted data. Two authors independently assessed the studies' risk of bias. They assessed the quality of the evidence using GRADE criteria.
MAIN RESULTS
Fourteen RCTs were included in the review. Data were extracted from 12 studies (622 women). The primary outcome was quality of life (QoL).Add-back therapy with medroxyprogesterone (MPA): no studies reported QoL or uterine bleeding. There was no evidence of effect in relation to bone mass (standardized mean difference (SMD) 0.38, 95% confidence interval (CI) -0.62 to 1.38, 1 study, 16 women, P = 0.45, low quality evidence) and MPA was associated with a larger uterine volume (mean difference (MD) 342.19 cm(3), 95% CI 77.58 to 606.80, 2 studies, 32 women, I(2) = 0%, low quality evidence).Tibolone: this was associated with a higher QoL but the estimate was imprecise and the effect could be clinically insignificant, small or large (SMD 0.47, 95% CI 0.09 to 0.85, 1 study, 110 women, P = 0.02, low quality evidence). It was also associated with a decreased loss of bone mass, which could be insignificant, small or moderate (SMD 0.36, 95% CI 0.03 to 0.7, 3 studies, 160 women, I(2) = 7%, moderate quality evidence). Tibolone may, however, have been associated with larger uterine volumes (MD 23.89 cm(3), 95% CI= 8.13 to 39.66, 6 studies, 365 women, I(2) = 0%, moderate quality evidence) and more uterine bleeding (results were not combined but three studies demonstrated greater bleeding with tibolone while two other studies demonstrated no bleeding in either group). Four studies (268 women; not pooled owing to extreme heterogeneity) reported a large benefit on vasomotor symptoms in the tibolone group.Raloxifene: there was no evidence of an effect on QoL (SMD 0.11, 95% CI -0.57 to 0.34, 1 study, 74 women, P = 0.62, low quality evidence), while there was a beneficial impact on bone mass (SMD 1.01, 95% CI 0.57 to 1.45, 1 study, 91 women, P < 0.00001, low quality evidence). There was no clear evidence of effect on uterine volume (MD 27.1 cm(3), 95% CI -17.94 to 72.14, 1 study, 91 women, P = 0.24, low quality evidence), uterine bleeding or severity of vasomotor symptoms (MD 0.2 hot flushes/day, 95% CI -0.34 to 0.74, 1 study, 91 women, P = 0.46, low quality evidence).Estriol: no studies reported QoL, uterine size, uterine bleeding or vasomotor symptoms. Add-back with estriol may have led to decreased loss of bone mass, from results of a single study (SMD 3.93, 95% CI 1.7 to 6.16, 1 study, 12 women, P = 0.0005, low quality evidence).Ipriflavone: no studies reported QoL, uterine size or uterine bleeding. Iproflavone was associated with decreased loss of bone mass in a single study (SMD 2.71, 95% CI 2.14 to 3.27, 1 study, 95 women, P < 0.00001, low quality evidence); there was no evidence of an effect on the rate of vasomotor symptoms (RR 0.67, 95% Cl 0.44 to 1.02, 1 study, 95 women, P = 0.06, low quality evidence).Conjugated estrogens: no studies reported QoL, uterine size, uterine bleeding or vasomotor symptoms. One study suggested that adding conjugated estrogens to GnRH analogues resulted in a larger decrease in uterine volume in the placebo group (MD 105.2 cm(3), 95% CI 27.65 to 182.75, 1 study, 27 women, P = 0.008, very low quality evidence).Nine of 12 studies were at high risk of bias in at least one domain, most commonly lack of blinding. All studies followed participants for a maximum of six months. This short-term follow-up is usually insufficient to observe any significant effect of the treatment on bone health (such as the occurrence of fractures), limiting the findings.
AUTHORS' CONCLUSIONS
There was low or moderate quality evidence that tibolone, raloxifene, estriol and ipriflavone help to preserve bone density and that MPA and tibolone may reduce vasomotor symptoms. Larger uterine volume was an adverse effect associated with some add-back therapies (MPA, tibolone and conjugated estrogens). For other comparisons, outcomes of interest were not reported or study findings were inconclusive.

Review
BACKGROUND
Ovarian cancer (OC) has the highest case fatality rate of all gynaecological cancers. Diagnostic delays are caused by non-specific symptoms. Existing systematic reviews have not comprehensively covered tests in current practice, not estimated accuracy separately in pre- and postmenopausal women, or used inappropriate meta-analytic methods.
OBJECTIVES
To establish the accuracy of combinations of menopausal status, ultrasound scan (USS) and biomarkers for the diagnosis of ovarian cancer in pre- and postmenopausal women and compare the accuracy of different test combinations.
SEARCH METHODS
We searched CENTRAL, MEDLINE (Ovid), Embase (Ovid), five other databases and three trial registries from 1991 to 2015 and MEDLINE (Ovid) and Embase (Ovid) form June 2015 to June 2019. We also searched conference proceedings from the European Society of Gynaecological Oncology, International Gynecologic Cancer Society, American Society of Clinical Oncology and Society of Gynecologic Oncology, ZETOC and Conference Proceedings Citation Index (Web of Knowledge). We searched reference lists of included studies and published systematic reviews.
SELECTION CRITERIA
We included cross-sectional diagnostic test accuracy studies evaluating single tests or comparing two or more tests, randomised trials comparing two or more tests, and studies validating multivariable models for the diagnosis of OC investigating test combinations, compared with a reference standard of histological confirmation or clinical follow-up in women with a pelvic mass (detected clinically or through USS) suspicious for OC.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted data and assessed quality using QUADAS-2. We used the bivariate hierarchical model to indirectly compare tests at commonly reported thresholds in pre- and postmenopausal women separately. We indirectly compared tests across all thresholds and estimated sensitivity at fixed specificities of 80% and 90% by fitting hierarchical summary receiver operating characteristic (HSROC) models in pre- and postmenopausal women separately.
MAIN RESULTS
We included 59 studies (32,059 women, 9545 cases of OC). Two tests evaluated the accuracy of a combination of menopausal status and USS findings (IOTA Logistic Regression Model 2 (LR2) and the Assessment of Different NEoplasias in the adneXa model (ADNEX)); one test evaluated the accuracy of a combination of menopausal status, USS findings and serum biomarker CA125 (Risk of Malignancy Index (RMI)); and one test evaluated the accuracy of a combination of menopausal status and two serum biomarkers (CA125 and HE4) (Risk of Ovarian Malignancy Algorithm (ROMA)). Most studies were at high or unclear risk of bias in participant, reference standard, and flow and timing domains. All studies were in hospital settings. Prevalence was 16% (RMI, ROMA), 22% (LR2) and 27% (ADNEX) in premenopausal women and 38% (RMI), 45% (ROMA), 52% (LR2) and 55% (ADNEX) in postmenopausal women. The prevalence of OC in the studies was considerably higher than would be expected in symptomatic women presenting in community-based settings, or in women referred from the community to hospital with a suspicion of OC. Studies were at high or unclear applicability because presenting features were not reported, or USS was performed by experienced ultrasonographers for RMI, LR2 and ADNEX. The higher sensitivity and lower specificity observed in postmenopausal compared to premenopausal women across all index tests and at all thresholds may reflect highly selected patient cohorts in the included studies. In premenopausal women, ROMA at a threshold of 13.1 (± 2), LR2 at a threshold to achieve a post-test probability of OC of 10% and ADNEX (post-test probability 10%) demonstrated a higher sensitivity (ROMA: 77.4%, 95% CI 72.7% to 81.5%; LR2: 83.3%, 95% CI 74.7% to 89.5%; ADNEX: 95.5%, 95% CI 91.0% to 97.8%) compared to RMI (57.2%, 95% CI 50.3% to 63.8%). The specificity of ROMA and ADNEX were lower in premenopausal women (ROMA: 84.3%, 95% CI 81.2% to 87.0%; ADNEX: 77.8%, 95% CI 67.4% to 85.5%) compared to RMI 92.5% (95% CI 90.3% to 94.2%). The specificity of LR2 was comparable to RMI (90.4%, 95% CI 84.6% to 94.1%). In postmenopausal women, ROMA at a threshold of 27.7 (± 2), LR2 (post-test probability 10%) and ADNEX (post-test probability 10%) demonstrated a higher sensitivity (ROMA: 90.3%, 95% CI 87.5% to 92.6%; LR2: 94.8%, 95% CI 92.3% to 96.6%; ADNEX: 97.6%, 95% CI 95.6% to 98.7%) compared to RMI (78.4%, 95% CI 74.6% to 81.7%). Specificity of ROMA at a threshold of 27.7 (± 2) (81.5, 95% CI 76.5% to 85.5%) was comparable to RMI (85.4%, 95% CI 82.0% to 88.2%), whereas for LR2 (post-test probability 10%) and ADNEX (post-test probability 10%) specificity was lower (LR2: 60.6%, 95% CI 50.5% to 69.9%; ADNEX: 55.0%, 95% CI 42.8% to 66.6%).
AUTHORS' CONCLUSIONS
In specialist healthcare settings in both premenopausal and postmenopausal women, RMI has poor sensitivity. In premenopausal women, ROMA, LR2 and ADNEX offer better sensitivity (fewer missed cancers), but for ROMA and ADNEX this is off-set by a decrease in specificity and increase in false positives. In postmenopausal women, ROMA demonstrates a higher sensitivity and comparable specificity to RMI. ADNEX has the highest sensitivity in postmenopausal women, but reduced specificity. The prevalence of OC in included studies is representative of a highly selected referred population, rather than a population in whom referral is being considered. The comparative accuracy of tests observed here may not be transferable to non-specialist settings. Ultimately health systems need to balance accuracy and resource implications to identify the most suitable test.

BACKGROUND
Advanced pelvic radiotherapy techniques aim to reduce late bowel toxicity which can severely impact the lives of pelvic cancer survivors. Although advanced techniques have been largely adopted worldwide, to achieve their aim, knowledge of which dose-volume parameters of which components of bowel predict late bowel toxicity is crucial to make best use of these techniques. The rectum is an extensively studied organ at risk (OAR), and dose-volume predictors of late toxicity for the rectum are established. However, for other components of bowel, there is a significant paucity of knowledge. The Quantitative Analyses of Normal Tissue Effects in the Clinic (QUANTEC) reviews recommend dose-volume constraints for acute bowel toxicity for peritoneal cavity and bowel loops, although no constraints are recommended for late toxicity, despite its relevance to our increasing number of survivors. This systematic review aims to examine the published literature to seek dose-volume predictors and constraints of late bowel toxicity for OARs (apart from the rectum) for use in clinical practice.
METHODS
A systematic literature search was performed using Medline, Embase, Cochrane Library, Web of Science, Cinahl and Pubmed. Studies were screened and included according to specific pre-defined criteria. Included studies were assessed for quality against QUANTEC-defined assessment criteria.
RESULTS
101 studies were screened to find 30 relevant studies. Eight studies related to whole bowel, 11 to small bowel, and 21 to large bowel (including 16 of the anal canal). The anal canal is an important OAR for the development of late toxicity, and we recommend an anal canal Dmean <40Gy as a constraint to reduce late incontinence. For other components of bowel (sigmoid, large bowel, intestinal cavity, bowel loops), although individual studies found statistically significant parameters and constraints these findings were not corroborated in other studies.
CONCLUSIONS
The anal canal is an important OAR for the development of late bowel toxicity symptoms. Further validation of the constraints found for other components of bowel is needed. Studies that were more conclusive included those with patient-reported data, where individual symptom scores were assessed rather than an overall score, and those that followed statistical and endpoint criteria as defined by QUANTEC.

Meta-Analysis
CONTEXT
Pharmacological thromboprophylaxis involves balancing a lower risk of venous thromboembolism (VTE) against a higher risk of bleeding, a trade-off that critically depends on the risks of VTE and bleeding in the absence of prophylaxis (baseline risk).
OBJECTIVE
To provide estimates of the baseline risk of symptomatic VTE and bleeding requiring reoperation in urological cancer surgery.
EVIDENCE ACQUISITION
We identified contemporary observational studies reporting symptomatic VTE or bleeding after urological procedures. We used studies with the lowest risk of bias and accounted for use of thromboprophylaxis and length of follow-up to derive best estimates of the baseline risks within 4 wk of surgery. We used the GRADE approach to assess the quality of the evidence.
EVIDENCE SYNTHESIS
We included 71 studies reporting on 14 urological cancer procedures. The quality of the evidence was generally moderate for prostatectomy and cystectomy, and low or very low for other procedures. The duration of thromboprophylaxis was highly variable. The risk of VTE in cystectomies was high (2.6-11.6% across risk groups) whereas the risk of bleeding was low (0.3%). The risk of VTE in prostatectomies varied by procedure, from 0.2-0.9% in robotic prostatectomy without pelvic lymph node dissection (PLND) to 3.9-15.7% in open prostatectomy with extended PLND. The risk of bleeding was 0.1-1.0%. The risk of VTE following renal procedures was 0.7-2.9% for low-risk patients and 2.6-11.6% for high-risk patients; the risk of bleeding was 0.1-2.0%.
CONCLUSIONS
Extended thromboprophylaxis is warranted in some procedures (eg, open and robotic cystectomy) but not others (eg, robotic prostatectomy without PLND in low-risk patients). For "close call" procedures, decisions will depend on values and preferences with regard to VTE and bleeding.
PATIENT SUMMARY
Clinicians often give blood thinners to patients to prevent blood clots after surgery for urological cancer. Unfortunately, blood thinners also increase bleeding. This study provides information on the risk of clots and bleeding that is crucial in deciding for or against giving blood thinners.

Meta-Analysis
OBJECTIVE
To evaluate the survival impact of imaging vs surgical nodal assessment in patients with cervical cancer stage IB2-IVA prior to definitive chemoradiotherapy (CRT).
METHODS
PubMed, MEDLINE, Cochrane Library, and ClinicalTrials.gov were used to search for publications in English and Chinese over a 50-year period. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols was used to conduct this review. Inclusion criteria were studies that compared survival outcomes in International Federation of Gynecology and Obstetrics 2009 stage IB2-IVA cervical cancer patients with pre-therapy pelvic and/or aortic lymphadenectomy (LND) or imaging. One or more of the following modalities were used for nodal assessment: computed tomography (CT), magnetic resonance imaging, or positron emission tomography-CT. The National Institutes of Health Quality Assessment Tool was utilized to assess study quality.
RESULTS
The initial search identified 65 studies, and five met the inclusion criteria. There were a total of 1,112 patients. Seven hundred and fifty-four underwent pelvic and/or aortic LND and 358 had imaging. When compared to LND, imaging had a sensitivity and specificity of 88.9% and 22.2% for pelvic lymph node (LN), and 33%-62.5% and 92%-95.5% for para-aortic LN. There were no differences in progression-free survival (PFS) (hazard ratio [HR]=1.13; 95% confidence interval [CI]=0.73-1.74; I²=75%; p<0.01) and overall survival (OS) (HR=1.06; 95% CI=0.66-1.69; I²=75%; p<0.01) between surgical and imaging nodal assessment.
CONCLUSIONS
Imaging and surgical nodal assessment has comparable PFS and OS in patients with cervical cancer stage IB2-IVA.

Meta-Analysis
OBJECTIVE
The purpose of this network meta-analysis was to compare the effectiveness and adverse effects of limited, standard, extended, and super-extended pelvic lymph node dissection (PLND) following radical prostatectomy.
METHODS
This study followed the PRISMA 2020 statement. Clinical trials were searched from three electronic databases, including PubMed, the Cochrane Library, and Embase from the database's inception to April 5, 2022. The lymph node-positive rate, biochemical recurrence-free rate, lymphocele rate, thromboembolic rate, and overall complication rate were compared by meta-analysis. Data analyses were performed using R software based on the Bayesian framework.
RESULTS
Sixteen studies involving 15,269 patients were included. All 16 studies compared the lymph node-positive rate; 5 studies compared the biochemical recurrence-free rate; 10 studies compared the lymphocele rate; 6 studies compared the thromboembolic rate, and 9 studies compared the overall complication rate. According to Bayesian analysis, the lymph node-positive rate, lymphocele rate, and overall complication rate were significantly associated with the extension of the PLND range. The limited, extended, and super-extended PLND templates showed a similar but lower biochemical recurrence-free rate and a higher thromboembolic rate than the standard template.
CONCLUSIONS
The extension of the PLND range is associated with an elevated lymph node-positive rate; however, it does not improve the biochemical recurrence-free rate and correlates with an increased risk of complications, especially lymphocele. The selection of the PLND range in clinical practice should consider the oncological risk and adverse effects.

Review
PURPOSE
The aim of this study was to investigate the result of hyperbaric oxygen therapy (HBOT) in women with treated gynaecological malignancies who suffer from late radiation-induced tissue toxicity (LRITT). Moreover, which symptoms of LRITT benefit most from HBOT was evaluated as well.
MATERIAL AND METHODS
An online literature search was conducted using PubMed; Embase and the Cochrane Library. Studies were included if the study examined gynaecological cancer patients who had been treated with radiotherapy, who suffered from LRITT and who subsequently received HBOT. In addition, the outcome measures were based on examining the effects of HBOT.
RESULTS
Twenty-one articles were included. The study investigating proctitis reported an improvement and three out of four studies investigating cystitis reported decreased complaints in women treated for gynaecological malignancies. In addition, all studies reported improvement in patients with wound complications and fifty percent of the studies reported better Patient Reported Outcome Measurements (PROMS) in women with gynaecological malignancies. Finally, all studies, except one related to pelvic malignancies reported reduced prevalence of symptoms for cystitis and proctitis and all studies reported better PROMS. However, only eleven studies reported p-values, nine of which were significant.
CONCLUSION
This study demonstrated that HBOT has a positive effect in women with gynaecological LRITT. Within the included patient group, gynaecological cancer patients with wound complications seem to benefit most from this treatment compared to other late side effects of LRITT.
