Transarterial radioembolization for hepatocellular carcinoma with major vascular invasion: a nationwide propensity score-matched analysis with target trial emulation.
This study’s objective was to compare overall survival (OS) rates for hepatocellular carcinoma (HCC) with major vascular invasion (HCC-MVI) for patients undergoing either transarterial radioembolization (TARE) or systemic therapy. The National Cancer Database was used to identify 1,514 patients with HCC-MVI. TARE use had doubled between 2010 and 2015. OS was compared for the two treatments and TARE was found to be associated with significant survival benefits compared with systemic therapy.

Radiation therapy for brain metastases: a systematic review.
This systematic review synthesizes the available evidence on radiation therapy for brain metastases. A literature search was conducted using the major medical databases and included randomized controlled trials and large observational studies which evaluated whole brain radiation therapy (WBRT) and stereotactic radiosurgery (SRS) alone or in combination as initial or postoperative treatment, with or without systemic therapy for adults with brain metastases due to lung cancer, breast cancer, or melanoma. No statistically significant difference in overall survival was found with a combination of SRS plus WBRT compared with SRS alone or WBRT alone. Radiation therapy after surgery did not improve overall survival compared with surgery alone. WBRT plus systemic therapy was associated with increased risks for vomiting compared with WBRT alone. There was not enough data on patient-relevant outcomes such as quality of life, functional status, and cognitive effects.

Five-year outcomes from a prospective comparative effectiveness study evaluating external-beam radiotherapy with or without low-dose-rate brachytherapy boost for localized prostate cancer.
This retrospective cohort study’s objective was to determine if there were differences in treatment-related regret or survival between prostate cancer patients who received external-beam radiation therapy (EBRT) with or without a brachytherapy boost (EBRT-LDR), over a 5-year period. The cohort included 695 men who met inclusion criteria and received either EBRT (n=583) or EBRT-LDR (n=112). Men who received either treatment reported clinically worse urinary irritation and bowel function through 3 years but resolved after 5 years. Men who received EBRT-LDR continued to report moderate- to-big problems with urinary function bother and frequent urination at 5 years. There was no difference in treatment-related regret or survival between patients who received either treatment.

Reactions to recommendations and evidence about prostate cancer screening among White and Black male veterans.
This study looked at differences in attitudes about recommendations and evidence on prostate cancer screening among White and Black male veterans. The authors provided a draft educational pamphlet about the benefits and harms of Prostate Specific Antigen (PSA) screening to 44 men, ages 55-81 at a midwestern VA medical center in 2013 and 2015. The groups were divided into four White and two Black focus groups. Three universal themes were low baseline familiarity with prostate cancer, surprise and resistance to the guidelines not to test routinely, and negative emotions in response to ambiguity. Discussions in the White groups highlighted the potential benefits of screening, minimized the harms, and emphasized personal choice in screening decisions. Discussions in Black groups devoted almost no time to benefits, considered harms significant, and emphasized personal and collective responsibility for cancer prevention through diet, exercise, and alternative medicine. Discussion in Black groups also emphasized the history of racism and discrimination in healthcare and medical research.

Recurrence patterns after surgical resection of gastroenteropancreatic neuroendocrine tumors: analysis from the national comprehensive cancer network oncology outcomes database.
Current National Comprehensive Cancer Network guidelines for gastroenteropancreatic neuroendocrine tumors (GEPNETs) recommend complete (R0) surgical resection of the primary tumor and metastases, if feasible. This study conducted large multicenter studies of recurrence patterns of GEPNETs after resection. Findings showed that R0 resection was associated with variable risk of recurrence across subtypes. Recommendations included further research to inform refinement of guidelines for the appropriate duration of surveillance after R0 resection.

Therapies for clinically localized prostate cancer: a comparative effectiveness review.
In this study, the investigators sought to identify new information evaluating clinically localized prostate cancer therapies. The investigators concluded that radical prostatectomy reduced mortality vs watchful waiting in clinically detected localized prostate cancer but caused more harms. Effectiveness may be limited to younger men and those with intermediate risk disease. Active monitoring resulted in little to no mortality difference vs radical prostatectomy or external beam radiation plus androgen deprivation.

Evaluation of the benefits and harms of lung cancer screening with low-dose computed tomography: modeling study for the US Preventive Services Task Force.
The purpose of this study was to inform the USPSTF guidelines by estimating the benefits and harms associated with various low-dose computed tomography (LDCT) screening strategies. Microsimulation modeling studies suggested that LDCT screening for lung cancer compared with no screening may increase lung cancer deaths averted and life-years gained when optimally targeted and implemented. Screening individuals at aged 50 or 55 years through aged 80 years with 20 pack-years or more of smoking exposure was estimated to result in more benefits than the 2013 USPSTF-recommended criteria and less disparity in screening eligibility by sex and race/ethnicity.

Screening for lung cancer with low-dose computed tomography: updated evidence report and systematic review for the US Preventive Services Task Force.
The purpose of this study was to review the evidence on screening for lung cancer with low-dose computed tomography (LDCT) to inform the USPSTF. Findings showed that screening high-risk persons with LDCT can reduce lung cancer mortality but can also cause false-positive results leading to unnecessary tests and invasive procedures, overdiagnosis, incidental findings, increases in distress, and, rarely, radiation-induced cancers.

Nonpharmacological interventions for managing breathlessness in patients with advanced cancer: a systematic review.
The purpose of this review was to evaluate the advantages and harms of nonpharmacological interventions for managing breathlessness in adults with advanced cancer. PubMed, Embase, CINAHL, Web of Science, and the Cochrane Central Register of Controlled Trials databases were searched for English-language studies about randomized and nonrandomized clinical trials, controlled trials, and observational studies. Findings included the safety and association with improved breathlessness of several nonpharmacological interventions for adults with advanced cancer. Recommendations included incorporating nonpharmacological interventions as first-line treatment for adults with advanced cancer and breathlessness.

Pharmacologic interventions for breathlessness in patients with advanced cancer: a systematic review and meta-analysis.
This systematic review and meta-analysis examined the use of pharmacological interventions for breathlessness in patients with advanced cancer. Studies were identified from database inception to May 2020 using predefined eligibility criteria. Pharmacologic intervention benefits and harms were compared, focusing on breathlessness, anxiety, exercise capacity and health-related quality of life. Out of 7729 unique citations, 19 studies with a total of 1424 patients were included. Opioids were not associated with more effectiveness than placebo for improving breathlessness or exercise capacity. Anxiolytics were also not associated with more effectiveness than placebo for breathlessness or anxiety. There was limited evidence for other pharmacologic interventions. There was some harm, but it was minimal in those short-term studies.

Evaluation of revised US Preventive Services Task Force lung cancer screening guideline among women and racial/ethnic minority populations.
The purpose of this study was to determine the changes associated with the revised USPSTF guideline for lung cancer screening eligibility among female, Black, and Hispanic populations using a large nationwide survey. The investigators concluded that the revised USPSTF guideline may likely increase lung cancer screening rates for female, Black, and Hispanic populations. However, despite these potential improvements, lung cancer screening inequities may persist without tailored eligibility criteria.

Contemporary prostate cancer radiation therapy in the United States: patterns of care and compliance with quality measures.
This study measured compliance with quality measures for radiation therapy treatment of prostate cancer. The Comparative Effectiveness Analysis of Surgery and Radiation Study enrolled men who were treated for localized prostate cancer from 2011 and 2012. Medical records were reviewed, and patients completed surveys. Researchers concluded that men who received external beam radiation therapy (EBRT) were treated more appropriately than those treated with brachytherapy (BT). White men were also more likely to receive appropriate treatment than African-American and other minorities.

Impact of concurrent medication use on pancreatic cancer survival-SEER-Medicare analysis.
Researchers examined the association of several medication classes on pancreatic cancer survival, using data from the Surveillance, Epidemiology, and End Results-Medicare database. They found that the use of beta-blockers, heparin, insulin, and warfarin were associated with improved survival in patients with pancreatic cancer, whereas metformin, thiazolidinedione, statin, and combination therapies were not. The authors recommended additional studies to validate these findings in the clinical setting.

Effect of prostate cancer severity on functional outcomes after localized treatment: comparative effectiveness analysis of surgery and radiation study results.
The purpose of this study was to determine whether differences in predicted function over time between radical prostatectomy (RP) or external beam radiotherapy (EBRT) for localized cancer varied by risk group. Patient-reported, disease-specific function was measured using the Expanded Prostate Index Composite and predicted function was estimated using regression models, compared by disease risk. The study found that sexual function was similar between surgery and radiation for patients with high-risk disease, and the authors conclude that high-risk patients undergoing radiation therapy should be counseled that their sexual function may not be as good as low-risk patients also undergoing radiation.

Behavioral counseling for skin cancer prevention: evidence report and systematic review for the US Preventive Services Task Force.
The authors systematically reviewed the evidence on the benefits and harms of behavioral counseling for skin cancer prevention to inform the US Preventive Services Task Force (USPSTF). They concluded that behavioral interventions can increase sun protection behavior, but there is no consistent evidence that interventions are associated with a reduction in the frequency of sunburn in children or adults and minimal evidence on skin cancer outcomes.
