RESUMEN

Importance: Breast cancer is a leading cause of cancer mortality for US women. Trials have established that screening mammography can reduce mortality risk, but optimal screening ages, intervals, and modalities for population screening guidelines remain unclear. Objective: To review studies comparing different breast cancer screening strategies for the US Preventive Services Task Force. Data Sources: MEDLINE, Cochrane Library through August 22, 2022; literature surveillance through March 2024. Study Selection: English-language publications; randomized clinical trials and nonrandomized studies comparing screening strategies; expanded criteria for screening harms. Data Extraction and Synthesis: Two reviewers independently assessed study eligibility and quality; data extracted from fair- and good-quality studies. Main Outcomes and Measures: Mortality, morbidity, progression to advanced cancer, interval cancers, screening harms. Results: Seven randomized clinical trials and 13 nonrandomized studies were included; 2 nonrandomized studies reported mortality outcomes. A nonrandomized trial emulation study estimated no mortality difference for screening beyond age 74 years (adjusted hazard ratio, 1.00 [95% CI, 0.83 to 1.19]). Advanced cancer detection did not differ following annual or biennial screening intervals in a nonrandomized study. Three trials compared digital breast tomosynthesis (DBT) mammography screening with digital mammography alone. With DBT, more invasive cancers were detected at the first screening round than with digital mammography, but there were no statistically significant differences in interval cancers (pooled relative risk, 0.87 [95% CI, 0.64-1.17]; 3 studies [n = 130 196]; I2 = 0%). Risk of advanced cancer (stage II or higher) at the subsequent screening round was not statistically significant for DBT vs digital mammography in the individual trials. Limited evidence from trials and nonrandomized studies suggested lower recall rates with DBT. An RCT randomizing individuals with dense breasts to invitations for supplemental screening with magnetic resonance imaging reported reduced interval cancer risk (relative risk, 0.47 [95% CI, 0.29-0.77]) and additional false-positive recalls and biopsy results with the intervention; no longer-term advanced breast cancer incidence or morbidity and mortality outcomes were available. One RCT and 1 nonrandomized study of supplemental ultrasound screening reported additional false-positives and no differences in interval cancers. Conclusions and Relevance: Evidence comparing the effectiveness of different breast cancer screening strategies is inconclusive because key studies have not yet been completed and few studies have reported the stage shift or mortality outcomes necessary to assess relative benefits.

RESUMEN

Importance: Prostate cancer is the second leading cause of cancer death among US men. Objective: To systematically review evidence on prostate-specific antigen (PSA)-based prostate cancer screening, treatments for localized prostate cancer, and prebiopsy risk calculators to inform the US Preventive Services Task Force. Data Sources: Searches of PubMed, EMBASE, Web of Science, and Cochrane Registries and Databases from July 1, 2011, through July 15, 2017, with a surveillance search on February 1, 2018. Study Selection: English-language reports of randomized clinical trials (RCTs) of screening; cohort studies reporting harms; RCTs and cohort studies of active localized cancer treatments vs conservative approaches (eg, active surveillance, watchful waiting); external validations of prebiopsy risk calculators to identify aggressive cancers. Data Extraction and Synthesis: One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. Main Outcomes and Measures: Prostate cancer and all-cause mortality; false-positive screening results, biopsy complications, overdiagnosis; adverse effects of active treatments. Random-effects meta-analyses were conducted for treatment harms. Results: Sixty-three studies in 104 publications were included (N = 1 904 950). Randomization to PSA screening was not associated with reduced risk of prostate cancer mortality in either a US trial with substantial control group contamination (n = 76 683) or a UK trial with low adherence to a single PSA screen (n = 408 825) but was associated with significantly reduced prostate cancer mortality in a European trial (n = 162 243; relative risk [RR], 0.79 [95% CI, 0.69-0.91]; absolute risk reduction, 1.1 deaths per 10 000 person-years [95% CI, 0.5-1.8]). Of 61 604 men screened in the European trial, 17.8% received false-positive results. In 3 cohorts (n = 15 136), complications requiring hospitalization occurred in 0.5% to 1.6% of men undergoing biopsy after abnormal screening findings. Overdiagnosis was estimated to occur in 20.7% to 50.4% of screen-detected cancers. In an RCT of men with screen-detected prostate cancer (n = 1643), neither radical prostatectomy (hazard ratio [HR], 0.63 [95% CI, 0.21-1.93]) nor radiation therapy (HR, 0.51 [95% CI, 0.15-1.69]) were associated with significantly reduced prostate cancer mortality vs active monitoring, although each was associated with significantly lower risk of metastatic disease. Relative to conservative management, radical prostatectomy was associated with increased risk of urinary incontinence (pooled RR, 2.27 [95% CI, 1.82-2.84]; 3 trials; n = 1796) and erectile dysfunction (pooled RR, 1.82 [95% CI, 1.62-2.04]; 2 trials; n = 883). Relative to conservative management (8 cohort studies; n = 3066), radiation therapy was associated with increased risk of erectile dysfunction (pooled RR, 1.31 [95% CI, 1.20-1.42]). Conclusions and Relevance: PSA screening may reduce prostate cancer mortality risk but is associated with false-positive results, biopsy complications, and overdiagnosis. Compared with conservative approaches, active treatments for screen-detected prostate cancer have unclear effects on long-term survival but are associated with sexual and urinary difficulties.

RESUMEN

Importance: Cervical cancer can be prevented with detection and treatment of precancerous cell changes caused primarily by high-risk types of human papillomavirus (hrHPV), the causative agents in more than 90% of cervical cancers. Objective: To systematically review benefits and harms of cervical cancer screening for hrHPV to inform the US Preventive Services Task Force. Data Sources: MEDLINE, PubMed, PsycINFO, and the Cochrane Collaboration Registry of Controlled Trials from January 2011 through February 15, 2017; surveillance through May 25, 2018. Study Selection: Randomized clinical trials (RCTs) and cohort studies comparing primary hrHPV screening alone or hrHPV cotesting (both hrHPV testing and cytology) with cytology (Papanicolaou [Pap] test) screening alone. Data Extraction and Synthesis: Two investigators independently reviewed abstracts and full-text articles and quality rated included studies; data were qualitatively synthesized. Main Outcomes and Measures: Invasive cervical cancer; cervical intraepithelial neoplasia (CIN); false-positive, colposcopy, and biopsy rates; psychological harms. Results: Eight RCTs (n = 410 556), 5 cohort studies (n = 402 615), and 1 individual participant data (IPD) meta-analysis (n = 176 464) were included. Trials were heterogeneous for screening interval, number of rounds, and protocol. For primary hrHPV screening, evidence was consistent across 4 trials demonstrating increased detection of CIN 3 or worse (CIN 3+) in round 1 (relative risk [RR] range, 1.61 [95% CI, 1.09-2.37] to 7.46 [95% CI, 1.02-54.66]). Among 4 hrHPV cotesting trials, first-round CIN 3+ detection was not significantly different between screening groups; RRs for cumulative CIN 3+ detection over 2 screening rounds ranged from 0.91 to 1.13. In first-round screening, false-positive rates for primary hrHPV screening ranged from 6.6% to 7.4%, compared with 2.6% to 6.5% for cytology. For cotesting, false-positives ranged from 5.8% to 19.9% in the first round of screening, compared with 2.6% to 10.9% for cytology. First-round colposcopy rates were also higher, ranging 1.2% to 7.9% for primary hrHPV testing, compared with 1.1% to 3.1% for cytology alone; colposcopy rates for cotesting ranged from 6.8% to 10.9%, compared with 3.3% to 5.2% for cytology alone. The IPD meta-analysis of data from 4 cotesting trials and 1 primary hrHPV screening trial found lower risk of invasive cervical cancer with any hrHPV screening compared with cytology alone (pooled RR, 0.60 [95% CI, 0.40-0.89]). Conclusions and Relevance: Primary hrHPV screening detected higher rates of CIN 3+ at first-round screening compared with cytology. Cotesting trials did not show initial increased CIN 3+ detection. Both hrHPV screening strategies had higher false-positive and colposcopy rates than cytology, which could lead to more treatments with potential harms.

RESUMEN

BACKGROUND: Screening mammography has lower sensitivity and specificity in women with dense breasts, who experience higher breast cancer risk. PURPOSE: To perform a systematic review of reproducibility of Breast Imaging Reporting and Data System (BI-RADS) density categorization and test performance and clinical outcomes of supplemental screening with breast ultrasonography, magnetic resonance imaging (MRI), and digital breast tomosynthesis (DBT) in women with dense breasts and negative mammography results. DATA SOURCES: MEDLINE, PubMed, EMBASE, and Cochrane database from January 2000 to July 2015. STUDY SELECTION: Studies reporting BI-RADS density reproducibility or supplemental screening results for women with dense breasts. DATA EXTRACTION: Quality assessment and abstraction of 24 studies from 7 countries; 6 studies were good-quality. DATA SYNTHESIS: Three good-quality studies reported reproducibility of BI-RADS density; 13% to 19% of women were recategorized between "dense" and "nondense" at subsequent screening. Two good-quality studies reported that sensitivity of ultrasonography for women with negative mammography results ranged from 80% to 83%; specificity, from 86% to 94%; and positive predictive value (PPV), from 3% to 8%. The sensitivity of MRI ranged from 75% to 100%; specificity, from 78% to 94%; and PPV, from 3% to 33% (3 studies). Rates of additional cancer detection with ultrasonography were 4.4 per 1000 examinations (89% to 93% invasive); recall rates were 14%. Use of MRI detected 3.5 to 28.6 additional cancer cases per 1000 examinations (34% to 86% invasive); recall rates were 12% to 24%. Rates of cancer detection with DBT increased by 1.4 to 2.5 per 1000 examinations compared with mammography alone (3 studies). Recall rates ranged from 7% to 11%, compared with 7% to 17% with mammography alone. No studies examined breast cancer outcomes. LIMITATIONS: Good-quality evidence was sparse. Studies were small and CIs were wide. Definitions of recall were absent or inconsistent. CONCLUSION: Density ratings may be recategorized on serial screening mammography. Supplemental screening of women with dense breasts finds additional breast cancer but increases false-positive results. Use of DBT may reduce recall rates. Effects of supplemental screening on breast cancer outcomes remain unclear. PRIMARY FUNDING SOURCE: Agency for Healthcare Research and Quality.

RESUMEN

OBJECTIVE: To provide a scoping review of studies on empathy recognition in text using natural language processing (NLP) that can inform an approach to identifying physician empathic communication over patient portal messages. MATERIALS AND METHODS: We searched 6 databases to identify relevant studies published through May 1, 2023. The study selection was conducted through a title screening, an abstract review, and a full-text review. Our process followed the PRISMA-ScR guidelines. RESULTS: Of the 2446 publications identified from our searches, 39 studies were selected for the final review, which summarized: (1) definitions and context of empathy, (2) data sources and tested models, and (3) model performance. Definitions of empathy varied in their specificity to the context and setting of the study. The most common settings in which empathy was studied were reactions to news stories, health-related social media forums, and counseling sessions. We also observed an expected shift in methods used that coincided with the introduction of transformer-based models. DISCUSSION: Aspects of the current approaches taken across various domains may be translatable to communication over a patient portal. However, the specific barriers to identifying empathic communication in this context are unclear. While modern NLP methods appear to be able to handle empathy-related tasks, challenges remain in precisely defining and measuring empathy in text. CONCLUSION: Existing work that has attempted to measure empathy in text using NLP provides a useful basis for future studies of patient-physician asynchronous communication, but consideration for the conceptualization of empathy is needed.

RESUMEN

Breast cancer is the most common cancer among women worldwide, and survival rates are increasing. Chemotherapy-associated peripheral neuropathy (PN) is clinically important because of effects on quality of life (QOL) and potential effects on dose limitations. This adverse drug reaction is associated with certain classes of chemotherapy and commonly presents as peripheral sensory neuropathy whose natural course is largely unknown. The literature was reviewed to determine the frequency and characteristics of PN associated with adjuvant chemotherapy in early-stage breast cancer (ESBC) to explore the potential impact on long-term (one or more years after diagnosis) health outcomes and QOL. MEDLINE, PubMed, Embase, and the Cochrane Library were searched for relevant English-language randomized controlled trials, systematic reviews, meta-analyses, and case-control and cohort studies published between January 1990 and July 1996. Included studies were limited to current adjuvant regimens (eg, anthracyclines, taxanes, cyclophosphamide, platinum compounds). Two investigators independently reviewed abstracts, full-text articles, and extracted data from fair- and good-quality studies. Discrepancies in quality assessment and data extraction were resolved by consensus. We identified 364 articles; 60 were eligible for full-text review. Only five reports of four studies provided data beyond one year post-treatment initiation. Studies used different measures to assess PN. Neuropathic symptoms persisted in 11.0% to more than 80% of participants at one to three years following treatment. There is a paucity of data describing persistent PN in ESBC patients. Consistent use of validated measures and well-conducted randomized clinical trials or observational studies are needed to evaluate the incidence, persistence, and QOL associated with the long-term effects of PN.
