“I like SRDR’s use of the Tabs and the separation by topic area of the Tabs; it allows for focus on sections of a paper at a time. SRDR is powerful and adaptable, provides a way to standardize diverse results, and provides structure.“

“SRDR is one of the few data systems designed specifically for producing and archiving systematic reviews with the intention to share the data with the public. It’s extremely flexible and it allows users to design their forms (and data items on the forms) in a way that best suit their needs and workflow.”

“The structure of SRDR lends itself well to teaching metacognitive processes associated with linking the discrete steps of the evidence analysis process. Another benefit is the flexibility of SRDR to handle diagnostic accuracy as well as etiology, treatment, and prognosis questions during systematic reviews.”

Therapies for Clinically Localized Prostate Cancer [Entered Retrospectively]
67 Studies • 1 Key Questions • 1 Extraction Forms
Objectives: Structured Abstract Objective. To identify new information that updates findings from previous AHRQ and AUA funded reviews evaluating therapies for clinically localized prostate cancer (CLPC). Sources. Bibliographic databases (2013-January 2020);; systematic reviews Methods. Controlled studies of CLPC (T1-T3a) treatments with duration ≥5 years for mortality and metastases and ≥1 year for quality of life and harms. Interventions included watchful waiting (WW), active surveillance or monitoring (AS, AM), androgen deprivation (AD), focal and whole gland therapies or combinations. We evaluated how patient and tumor characteristics modify treatment outcomes and how provider/hospital characteristics modify effectiveness of radical prostatectomy (RP) compared to other therapies. One investigator rated risk of bias (ROB), extracted data, and assessed certainty of evidence; a second checked accuracy. We analyzed English-language studies with low or medium ROB. We incorporated findings from RCTs identified in the 2014 AHRQ and 2016 AUA funded reviews if new RCTs provided information on the same intervention comparison. We derived thresholds defining “small”, “moderate” and “large” effect, summarize key findings from prior reviews and the impact of new research. Results. We identified 67 eligible references; 17 unique RCTs. Among clinically, rather than PSA detected CLPC, WW may increase overall and prostate-cancer mortality, and metastases versus RP at 20+ years. Urinary and erectile dysfunction were lower with WW versus RP. WW‘s effect on mortality may have varied by tumor risk and age but not by race, health status, comorbidities or PSA. AM probably results in little to no difference in overall or prostate-cancer mortality in PSA detected CLPC versus RP or EBR plus AD through 10 years regardless of tumor risk. Metastases were infrequent but slightly higher with AM. Harms were greater with RP than AM and mixed between EBR plus AD versus AM. 3D-Conformal EBR and AD plus low-dose-rate brachytherapy (BT) provided a small reduction in all-cause mortality versus 3D-CRT and AD but little to no difference on metastases. EBR plus AD versus EBR alone may have resulted in a small reduction in overall and prostate-cancer mortality and metastases in higher risk disease but may increase sexual harms. EBR plus initiating neoadjuvant AD versus EBR plus initiating concurrent AD may result in little to no difference in mortality at 12 years and genitourinary toxicity at 3 years. Conventionally fractionated EBR versus ultra-hypofractionated EBR may result in little to no difference in mortality and metastasis at 5 years and urinary and bowel toxicity at 2 years. Limited evidence suggested that AS results in fewer harms than photodynamic therapy and laparoscopic RP resulted in more harms than robotic-assisted RP. There was little to no information on long-term comparative effectiveness of other treatments. No studies evaluated WW or AS in screen detected CLPC or MRI for risk assessment or were conducted since effective pharmacologic therapies for advanced disease. No studies assessed provider or hospital factors of RP comparative effectiveness. Conclusions. RP reduces mortality versus WW in clinically detected CLPC but causes more harms. Effectiveness may be limited to younger men, those with intermediate risk disease and requires many years to occur. AM results in little to no mortality difference versus RP or EBR plus AD. EBR plus AD reduces mortality versus EBR alone in higher risk CLPC but may worsen sexual function. Adding low-dose-rate BT to 3D-Conformal EBR and AD may reduce mortality in higher risk CLPC. Little information exists on other treatments or the effects of patient, tumor and provider factors. Large, long-term RCTs in PSA-detected and MRI staged CLPC are needed.

The effect of IDH inhibitors in AML patients.
4 Studies • 2 Key Questions • 1 Extraction Forms
Objectives: 12% of patients with AML harbor mutation at Isocitrate dehydrogenase enzyme (IDH).Mutations at these enzymes result in high level of R2 hydroxyglutarate which competes with 2-alpha-hydroxygluterate resulted in DNA and histone hypermethylation. DNA and histone hypermethylation inhibits cell differentiation and promotes leukemic transformation. Ivosidenib and Enasidenib are IDH inhibitors that promotes cell differentiation and showed promising activity in phase1 and 2 trials in relapse/refractory AML patients and in elderly patients who are not candidate for traditional induction regimens. In this systematic review and meta-analysis, we intend to integrate the results of phase1 and 2 trials that looked at the efficacy and the side effects of IDH inhibitor. Therefore,we will have a clearer picture regarding the efficacy and side effect of these medications.
