National trends in the use of PSA, urinalysis, and digital rectal exam for evaluation of lower urinary tract symptoms in men.

PURPOSE: The purpose of this study was to describe the practices of primary care physicians (PCPs) and urologists in their implementation of the 2010 American Urological Association (AUA) recommendations for the management of benign prostatic hyperplasia (BPH) in a nationally representative sample. METHODS: Data collected from 2008 to 2015 in the National Ambulatory Medical Care Survey (NAMCS) were used. Men aged 45 and older who presented with either a new complaint or exacerbation of lower urinary tract symptoms (LUTS) were included. Primary outcomes were the prevalence and determinants of prostate-specific antigen (PSA) testing, urinalysis (UA), and digital rectal exam (DRE), as all three were included in the AUA guidelines during the time period studied. In logistic regression analyses weighted to reflect national estimates, potential determinants of adherence for each testing modality were examined. RESULTS: Between 2008 and 2015, 878 visits met inclusion criteria, corresponding to 14,399,121 ambulatory visits for new or exacerbated LUTS. Weighted prevalence estimates were 24% for PSA testing (95% CI: 19-29%), 61% for urinalysis (95% CI: 56-66%), and 18% for DRE (95% CI: 15-23%). Age ≥ 75 years was associated with lower prevalence of testing for all three tests, and region was associated with different testing estimates for PSA and UA. Patients referred to urologists were more likely to receive a DRE, although overall rates of DRE decreased per additional year of data. CONCLUSIONS: Adherence to AUA guidelines for evaluation of LUTS in ambulatory visits was low in a nationally representative sample of Americans, particularly for PSA testing and DRE, suggesting substantial discordance between guidelines at the time and practice patterns. Practice patterns also differed by age and region. These discrepancies encourage increased education of providers in the implementation of the guidelines, particularly since they have been updated recently.

Partial response in non-resectable adenosquamous carcinoma of the pancreas with high tumour mutation burden treated with gemcitabine, nab-paclitaxel and pembrolizumab.

A previously healthy man in his 60s was diagnosed with a rare histological subtype of pancreatic cancer, adenosquamous carcinoma. After somatic mutation profiling, it was found that the tumour had microsatellite instability status high and a high tumour mutational burden. The patient was started on combination therapy with gemcitabine, nab-paclitaxel and pembrolizumab. Tumour size and biomarkers showed a dramatic response eventually leading to the patient being transitioned to maintenance therapy with pembrolizumab. The patient has demonstrated continued response since the start of the treatment. This is the first report in the literature showing a sustained response in this type of neoplasm that was treated with a checkpoint inhibitor, and thus adds to the evidence supporting universal somatic testing in all pancreatic cancers for a tailored approach to therapy.

Uncovering the Risks of Anticancer Therapy Through Incident Report Analysis Using a Newly Developed Medical Oncology Incident Taxonomy.

BACKGROUND: Incident reporting systems were developed to identify possible and actual harm in healthcare facilities. They have the potential to capture important safety trends and to enable improvements that can mitigate the risk of future patient harm and suffering. We recently developed and validated a taxonomy specific for medical oncology designed to enhance the identification, tracking, and trending of incidents that may lead to patient harm. The current project was designed to test the ability of such a taxonomy to be applied across different organizations delivering medical oncology care and to identify specific risks that could result in future harm. METHODS: We analyzed 309 randomly selected medical oncology-related incident reports from 3 different cancer centers that had been posted between January 2019 and December 2020. Each report was assigned up to 2 incident categories. We used a 2-step process to reconcile reviewer discrepancies. In a secondary analysis, each of the incidents was reviewed and recoded to identify events which may result in major or catastrophic harm. RESULTS: Three hundred four incidents met criteria for inclusion. Three hundred incidents (98.7%) were successfully coded. Sixty-seven percent of incidents were encompassed by the following 4 of 21 categories: prescriber ordering (22%), nursing care (15%), pharmacy (14%), and relational/communication issues (15%). Of 297 evaluable incidents, 47% did not reach the patient, 44.7% reached the patient without harm, 7.7% caused minor injury, and 0.7% caused severe injury or death. Submission rates by physicians varied between the 3 sites accounting for 1.7%, 10.7%, and 16.1% of reports. Secondary analysis identified 9 distinct scenarios that may result in major or catastrophic patient harm. CONCLUSIONS: A medical oncology-specific incident reporting taxonomy has the potential to increase our understanding of inherent risks and may lead to process improvements that improve patient safety.

Why focus on patient-reported outcome measures in older colorectal cancer patients?

Colorectal cancer is the most common cancer among older persons, with surgery the recommended treatment for many. With a growing emphasis on value-based care, there is an increasing desire to implement patient-reported outcome measures. Patient-reported outcome measures (PROMs) are the tools and instruments used to collect patient-reported symptoms, functional status, and quality of life. Monitoring and addressing PROMs has been shown to improve patient-centered care in surgical oncology populations and survival in patients with advanced cancer. For older patients, functional status and quality of life are valuable outcomes of cancer treatment. However, experience with PROMs for older patients, and specifically older colorectal cancer patients, is limited and heterogenous. The International Consortium for Health Outcomes Measurement has recommended a set of outcome measures for colorectal cancer patients and a set of outcome measures for older patients, which have considerable overlap, providing a starting point for future investigations of PROMs for older colorectal cancer patients. While many questions remain, it is imperative that PROMs for older colorectal cancer patients be considered for their potential to improve cancer outcomes in this population.

A cluster of amyotrophic lateral sclerosis in New Hampshire: a possible role for toxic cyanobacteria blooms.

Cyanobacteria produce many neurotoxins including beta-methylamino-L-alanine (BMAA) that has been liked to amyotrophic lateral sclerosis (ALS) and neurodegenerative disease. A number of ALS cases have been diagnosed among residents of Enfield, NH, a town encompassing a lake with a history of cyanobacteria algal blooms. To investigate an association between toxic cyanobacterial blooms in New Hampshire and development of ALS, we reviewed records from our institution and other community databases to obtain demographic information on patients diagnosed with ALS within New England. We identified nine ALS patients who lived near Lake Mascoma in Enfield, NH, an incidence of sporadic ALS that is 10 to 25 times the expected incidence of 2/100,000/year. We suggest that the high incidence of ALS in this potential cluster could be directly related to chronic exposure to cyanobacterial neurotoxins such as BMAA. Possible routes of toxin exposure include inhalation of aerosolized toxins, consuming fish, or ingestion of lake water. Further investigation, including analysis of brain tissue for cyanobacterial toxins, will be helpful to test for an association between BMAA and ALS.
