Surveillance Recommendations Research Articles

Re-examining mandatory drug testing in Australian prisons.

Mandatory drug testing is commonly used in Australian prisons to detect and deter drug use. In this commentary, we review the limited evidence for mandatory drug testing programs, highlight potential harms associated with their implementation and provide recommendations for drug surveillance in prisons concordant with a harm minimisation framework.

Factors Associated with the Presence of E.coli in Food: Literature Review

Background: Escherichia coli is a gram-negative bacterium of normal flora of the human and animal digestive tracts, and is important in human digestion. These bacteria can live in the stool, and can cause health problems, such as: diarrhea, vomiting, and other digestive problems. E coli bacteria can be pathogenic if the number of bacteria in the digestive tract increases or is outside the intestine. Food Sanitation Efforts include supervision, protection, and improvement of hygiene and sanitation quality specifically for Ready-to-Eat Processed Foods. Food hygiene and sanitation quality supervision is carried out through: surveillance, laboratory tests, risk analysis, and/or follow-up recommendations. Protection of food hygiene and sanitation quality is carried out through: communication, information, and education; health checks of food handlers; use of personal protective equipment; and/or the development of appropriate technology. Improving the quality of food hygiene and sanitation is carried out through: communication, information, and education; and/or food processing technology engineering Objective: The purpose of this literature review is to find out the factors related to the presence of E.coli in food Method: The research method used is a literature study with a search method in a literature review, which searches for literature that is in accordance with relevant social media such as google scholar, garuda, e-journal in the field of diarrhea incidence. Search the literature as a reference from 2014-2024 and get 10 articles or journals that are relevant in the last 10 years. Results: The results of this literature review explain that factors related to the presence of e.coli in food in public places include: personal hygiene of food handlers, how to wash cutlery, PPE of food handlers are not paid attention to, poor food sanitation, food handlers do not pay attention to controlling environmental conditions from the handling of raw materials to the distribution process, the storage place of cutlery is not considered, and improper serving of food. Conclusion: The conclusion of this literature review article is that there are many factors related to the presence of e.coli in food in public places. And recommend to environmental health workers the need to socialize and supervise the hygiene and sanitation of traders in particular. To the general public to pay attention to the cleanliness of what will be consumed.

Monkeypox infection and pregnancy in lower and middle-income countries: Precautions & recommendations.

Monkeypox (MPX), an orthopoxviral disease endemic in Africa, is now a public health emergency of international concern (PHEIC) as declared by the World Health Organization in July 2023. Although it is generally mild, the overall case fatality rate was reported to be 3%, and the basic reproduction number (R0) is > 1 in men who have sex with men (MSM, i.e., Portugal (1.4), the United Kingdom (1.6), and Spain (1.8)). However, R0 is < 1 in other settings. In concordance with the smallpox virus, it is also expected to increase the risk of adverse outcomes for both the mother and the fetus. The outcomes of the disease in an immunocompromised state of pregnancy are scary, showing high mortality and morbidity of both mother and fetus, with up to a 75% risk of fetal side effects and a 25% risk of severe maternal diseases. Therefore, it warrants timely diagnosis and intervention. The reverse transcription polymerase chain reaction (RT PCR) test is the standard approach to diagnosis. We summarized the recent findings of MPX on pregnancy, and the associated risk factors. We also give recommendations for active fetal surveillance, perinatal care, and good reporting to improve outcomes. The available vaccines have shown promise for primary disease prevention.

Risk factors for advanced colorectal neoplasia and colorectal cancer detected at surveillance: a nationwide study in the modern era.

Recommendations for surveillance after colonoscopy are based on risk factors for metachronous advanced colorectal neoplasia (AN) and colorectal cancer (CRC). The value of these risk factors remains unclear in populations enriched by individuals with a positive faecal immunochemical test and were investigated in a modern setting. This population-based cohort study included all individuals in the Netherlands of ≥55 years old with a first adenoma diagnosis in 2015. A total of 22,471 patients were included. Data were retrieved from the Dutch Nationwide Pathology Databank (Palga). Primary outcomes were metachronous AN and CRC. Patient and polypcharacteristics were evaluated by multivariable Cox regression analyses. During follow-up, 2416 (10.8%) patients were diagnosed with AN, of which 557 (2.5% from the total population) were CRC. Adenomas with high-grade dysplasia (hazard ratio [HR] 1.60, 95% confidence interval [CI] 1.40-1.83), villous histology (HR 1.91, 95% CI 1.59-2.28), size ≥10 mm (HR 1.12, 95% CI 1.02-1.23), proximal location (HR 1.12, 95% CI 1.02-1.23), two or more adenomas (HR 1.28, 95% CI 1.16-1.41), and serrated polyps ≥10 mm (HR 1.67, 95% CI 1.42-1.97) were independent risk factors for metachronous AN. In contrast, only adenomas with high-grade dysplasia (HR 2.49, 95% CI 1.92-3.24) were an independent risk factor for metachronous CRC. Risk factors for metachronous AN and CRC were identified for populations with access to a faecal immunochemical test (FIT)-based screening programme. If only risk factors for metachronous CRC are considered, a reduction in criteria for surveillance seems reasonable.

Neuroblastoma Predisposition and Surveillance-An Update from the 2023 AACR Childhood Cancer Predisposition Workshop.

Genetic predisposition to neuroblastoma (NB) is relatively rare. Only 1% to 2% of patients have a family history of NB, 3% to 4% of cases present with bilateral or multifocal primary tumors, and occasional patients have syndromes that are associated with increased NB risk. Previously, a germline pathogenic variant (GPV) in PHOX2B was associated with Hirschsprung disease and congenital central hypoventilation syndrome. Recently, certain GPVs were shown to be responsible for congenital central hypoventilation syndrome and NB predisposition. Also, several groups determined that activating GPVs in ALK accounted for a substantial number of familial NB. Finally, there are additional genes and cancer predisposition syndromes in which NB occurs with greater frequency or that have been associated with NB based on genome-wide association studies. We review the evidence for all these genes and whether there is sufficient evidence to warrant surveillance. We review recommended surveillance for hereditary patients with NB, including minor updates to surveillance recommendations that were published previously in 2017.

Cancer predisposing syndromes in childhood and adolescence pose several challenges necessitating interdisciplinary care in dedicated programs.

Genetic disposition is a major etiologic factor in childhood cancer. More than 100 cancer predisposing syndromes (CPS) are known. Surveillance protocols seek to mitigate morbidity and mortality. To implement recommendations in patient care and to ascertain that the constant gain of knowledge forces its way into practice specific pediatric CPS programs were established. We retrospectively analyzed data on children, adolescents, and young adults referred to our pediatric CPS program between October 1, 2021, and March 31, 2023. Follow-up ended on December 31, 2023. We identified 67 patients (30 male, 36 female, 1 non-binary, median age 9.5 years). Thirty-five patients were referred for CPS surveillance, 32 for features suspicious of a CPS including café-au-lait macules (n = 10), overgrowth (n = 9), other specific symptoms (n = 4), cancer suspicious of a CPS (n = 6), and rare neoplasms (n = 3). CPS was confirmed by clinical criteria in 6 patients and genetic testing in 7 (of 13). In addition, 6 clinically unaffected at-risk relatives were identified carrying a cancer predisposing pathogenic variant. A total of 48 patients were eventually diagnosed with CPS, surveillance recommendations were on record for 45. Of those, 8 patients did not keep their appointments for various reasons. Surveillance revealed neoplasms (n = 2) and metachronous tumors (n = 4) by clinical (n = 2), radiological examination (n = 2), and endoscopy (n = 2). Psychosocial counselling was utilized by 16 (of 45; 35.6%) families. The diverse pediatric CPSs pose several challenges necessitating interdisciplinary care in specified CPS programs. To ultimately improve outcome including psychosocial well-being joint clinical and research efforts are necessary.

Pathogenic germline variant discovery in plasma cell disorders: Insights from genetic counseling referrals and testing.

10619 Background: Our research has shown that 10% of multiple myeloma (MM) patients harbor pathogenic or likely-pathogenic germline variants (PGVs) in cancer predisposition genes, with a significant enrichment observed in BRCA1/2 genes. PGVs are notably more common in younger MM patients and those with a personal or familial cancer history. This study presents our experience in referring plasma cell disorder (PCD) patients at increased risk for carrying PGVs, due to either clinical history or suspicious tumor NGS findings, for genetic counseling and subsequent germline testing. Methods: This retrospective study reviewed patient records from our institution's PCD clinic, focusing on those referred for a genetic evaluation between 2020 and 2024 due to suspected cancer predisposition. We compiled demographic and clinical data for these patients, reasons for referral, and cancer history of patients and their families. The uptake of germline testing, identified mutations, and subsequent recommendations for advanced cancer surveillance and prevention, including cascade testing, were also analyzed. Germline testing utilized targeted hereditary cancer panels from five companies and was conducted on DNA samples extracted from peripheral blood, saliva/buccal swabs, or skin biopsies. Results: 52 PCD patients underwent a genetic evaluation and were included in this review, comprising 31 MM, 9 smoldering MM, and 12 MGUS cases. Median age at the time of referral was 63, and 54% of patients were female. Racial composition was 62% White, 15% Black/African-American, 12% Hispanic, 2% Asian, with 10% undisclosed. 8 patients were referred due to suspicious findings in tumor NGS, while the rest were referred due to clinical suspicion. A personal history of cancer was reported by 19 patients (37%), and 49 had a first- or second-degree relative with cancer (94%). 38 patients (73%) underwent germline testing, of which 15 (39%) harbored PGVs (11 had MM, 4 had smoldering MM). 8 PGV carriers had well-established founder variants. The remaining 7 had PGVs in genes including BRCA2 (n=3), PALB2 (n=1), BLM (n=1), SMAD4 (n=1) and NTHL1 (n=1). Of note, all 8 referred for suspicious findings in tumor NGS were confirmed to harbor PGVs. All PGV-positive patients were recommended for cascade testing and enhanced cancer screening. Conclusions: Our findings indicate a 39% PGV detection rate in PCD patients referred for genetic evaluation, underscoring the potential benefit of implementing screening guidelines in this population. PGV detection led to recommendations for intensified surveillance and cascade testing in all cases, impacting both patients and their families. The discovery of BRCA2PGVs in 20% (3/15) of cases reinforces its potential role as a predisposition gene in MM, corroborating our prior findings.

Endoscopic management of patients with familial adenomatous polyposis after prophylactic colectomy or restorative proctocolectomy - systematic review of the literature.

Patients with familial adenomatous polyposis (FAP) develop early colorectal adenomas and if left untreated, progression to cancer is an inevitable event. Prophylactic surgery does not prevent further development of cancer in the rectal remnant, rectal cuff in patients with ileal pouch anal anastomosis (IPAA) and even on the ileal mucosa of the pouch body. The aim of this review is to assess long-term rates of cancer and adenoma development in patients with FAP after prophylactic surgery and to summarise current recommendations for endoscopic management and surveillance of these patients. A systematic literature search of studies from January 1946 through to June 2023 was conducted using the PRISMA checklist. The electronic database PubMed was searched. Fifty-four papers involving 5010 patients were reviewed. Cancer rate in the rectal remnant was 8.8-16.7% in the western population and 37% in the eastern population. The cumulative risk of cancer 30 years after surgery was 24%. Mortality due to cancer in the rectal remnant is 1.1-11.1% with a 5-year survival rate of 55%. The adenoma rate after primary IPAA was 9.4-85% with a cumulative risk of 85% 20 years after surgery and a cumulative risk of 12% for advanced adenomas 10 years after surgery. Cumulative risk for adenomas after ileorectal anastomosis (IRA) was 85% after 5 and 100% after 10 years. Adenomas developed more frequently after stapled (33.9-57%) compared to hand-sewn (0-33%) anastomosis. We identified reports of 45 cancers in patients after IPAA of which 30 were in the pouch body and 15 in the rectal cuff or at the anastomosis. There was a significant incidence of cancer and adenomas in the rectal remnant and ileal pouch of FAP patients during the long-term follow-up. Regular endoscopic surveillance is recommended, not only in IRA patients, but also in pouch patients after proctocolectomy.

Increased Active Inflammation in the Colon is Not a Reliable Predictor of an Elevated Risk of Dysplasia in Patients With Primary Sclerosing Cholangitis and Ulcerative Colitis.

Although the increased risk of colorectal neoplasia in patients with both primary sclerosing cholangitis (PSC) and ulcerative colitis (UC; termed PSC-UC) is well documented, the mechanism through which concomitant PSC increases the risk of colorectal neoplasia remains unclear. Given that the risk of colorectal neoplasia in UC is positively correlated with increased histologic inflammation, this study sought to investigate whether increased histologic inflammation could be used to stratify the risk of dysplasia development in patients with PSC-UC. Twenty patients with PSC-UC and dysplasia were compared with 30 control patients with PSC-UC who had no history of neoplasia. For each patient, all surveillance biopsies were scored using a 4-point scoring system: (1) no epithelial neutrophils = 0, (2) cryptitis only = 1, (3) cryptitis plus crypt abscess in <50% of crypts = 2, and (4) crypt abscess in ≥50% of crypts, erosion, neutrophilic exudate, and/or ulceration = 3. A score was designated for each biopsy, and both mean and maximum inflammation scores were calculated from all biopsies taken during each colonoscopy. The inflammation burden score was calculated for each surveillance interval by multiplying the average maximum score between each pair of surveillance episodes by the length of the surveillance interval in years. The average scores derived from all colonoscopies for each patient were used to determine the patient's overall mean, maximum, and inflammation burden scores. In both the dysplasia and control groups, the 3 summative inflammation scores were calculated independently for the entire colon, right colon, and left colon. The dysplasia group consisted of 14 (70%) men and 6 (30%) women, with a mean age of 27 years at UC diagnosis and a long history of pancolitis (mean duration: 17y). A total of 49 dysplastic lesions were detected in the dysplasia group, and 8 (40%) of the 20 patients had multifocal dysplasia. The majority of dysplastic lesions belonged to nonconventional subtypes (n = 28; 57%) and were located in the right colon (n = 37; 76%). Irrespective of the colon segment, there was no significant difference in the 3 summative inflammation scores between the dysplasia and control groups ( P > 0.05). However, in each group, the 3 summative inflammation scores were significantly higher in the right colon than in the left colon ( P < 0.05). In conclusion, patients with PSC-UC exhibit increased histologic inflammation in the right colon compared with the left colon, regardless of the presence of dysplasia. Although this may provide an explanation for the predominance of right-sided colorectal neoplasia in patients with PSC-UC, increased histologic inflammation does not reliably predict an elevated risk of dysplasia in patients with PSC-UC. These findings reinforce the current recommendation for annual endoscopic surveillance for all patients with PSC-UC, irrespective of the extent and severity of inflammation.

Video Summarization using Object Detection Method

This project focuses on the integration of object detection techniques into the process of video summarization, harnessing the power of deep learning to automatically identify and extract key objects and events from video sequences. By leveraging state-of-the-art object detection models and innovative summarization algorithms, this project aims to enhance the efficiency and effectiveness of video summarization, enabling users to quickly grasp the content and significance of videos without the need for exhaustive playback. The proposed approach not only streamlines video browsing and content comprehension but also holds potential applications in various domains, including surveillance, video indexing, and content recommendation systems

From long-term follow-up Recommendations for clinical practice to plain language summaries for childhood, adolescent, and young adult cancer survivors

BackgroundHaving sufficient knowledge of cancer diagnosis, treatment and late effects in survivors of childhood, adolescent, and young adult (CAYA) cancer is important for effective self-management and optimising health outcomes. Therefore, in collaboration with different stakeholders, the PanCare PLAIN Information Group converted the PanCareFollowUp Recommendations for late effects surveillance into information summaries that are Person-centred, written in Lay language, Accessible, Internationally relevant, and Navigable (PLAIN). MethodsThe PanCare PLAIN Information Group, comprising 21 stakeholders from seven European countries, collaborated to provide concise information for survivors and their families. The aim was to deliver PLAIN summaries that are clear and accessible for the majority of survivors, while providing links to additional sources of information. The PLAIN summaries were drafted by the PanCare PLAIN Information Group and subjected to two internal and one external consultation round, the latter involving experts, CAYA cancer survivors and parents/caregivers. ResultsIn total, 45 PLAIN summaries were developed, each corresponding to one of the PanCareFollowUp Recommendations for late effects surveillance. The summaries provide information about late effects, personal health risks, important symptoms and signs, recommended surveillance strategies, possible referral and treatment options, and self-care. ConclusionsThe PLAIN summaries are meant to increase knowledge in survivors and their families, while they may also inform healthcare professionals. Along with their translations, the PLAIN summaries will be made freely available on the PanCare website, with a link provided on the European Network of Youth Cancer Survivors information platform. In addition, they will become and integral part of the Survivorship Passport.

ChatGPT4 Outperforms Endoscopists for Determination of Postcolonoscopy Rescreening and Surveillance Recommendations

Large language models including Chat Generative Pretrained Transformers version 4 (ChatGPT4) improve access to artificial intelligence, but their impact on the clinical practice of gastroenterology is undefined. This study compared the accuracy, concordance, and reliability of ChatGPT4 colonoscopy recommendations for colorectal cancer rescreening and surveillance with contemporary guidelines and real-world gastroenterology practice. History of present illness, colonoscopy data, and pathology reports from patients undergoing procedures at 2 large academic centers were entered into ChatGPT4 and it was queried for the next recommended colonoscopy follow-up interval. Using the McNemar test and inter-rater reliability, we compared the recommendations made by ChatGPT4 with the actual surveillance interval provided in the endoscopist's procedure report (gastroenterology practice) and the appropriate US Multisociety Task Force (USMSTF) guidance. The latter was generated for each case by an expert panel using the clinical information and guideline documents as reference. Text input of de-identified data into ChatGPT4 from 505 consecutive patients undergoing colonoscopy between January 1 and April 30, 2023, elicited a successful follow-up recommendation in 99.2% of the queries. ChatGPT4 recommendations were in closer agreement with the USMSTF Panel (85.7%) than gastroenterology practice recommendations with the USMSTF Panel (75.4%) (P < .001). Of the 14.3% discordant recommendations between ChatGPT4 and the USMSTF Panel, recommendations were for later screening in 26 (5.1%) and for earlier screening in 44 (8.7%) cases. The inter-rater reliability was good for ChatGPT4 vs USMSTF Panel (Fleiss κ, 0.786; 95% CI, 0.734-0.838; P < .001). Initial real-world results suggest that ChatGPT4 can define routine colonoscopy screening intervals accurately based on verbatim input of clinical data. Large language models have potential for clinical applications, but further training is needed for broad use.

Long-term cardiovascular disease risk after anthracycline and trastuzumab treatments in US breast cancer survivors.

Although breast cancer survivors are at risk for cardiovascular disease (CVD) from treatment late effects, evidence to inform long-term and age-specific cardiovascular surveillance recommendations is lacking. We conducted a retrospective cohort study of 10 211 women diagnosed with first primary unilateral breast cancer in Kaiser Permanente Washington or Colorado (aged 20 years and older, survived ≥1 year). We estimated multivariable adjusted hazard ratios (HRs) for associations between initial chemotherapy regimen type (anthracycline and/or trastuzumab, other chemotherapies, no chemotherapy [referent]) and CVD risk, adjusted for patient characteristics, other treatments, and CVD risk factors. Cumulative incidence was calculated considering competing events. After 5.79 median years, 14.67% of women developed CVD (cardiomyopathy and/or heart failure [HF], ischemic heart disease, stroke). Women treated with anthracyclines and/or trastuzumab had a higher risk of CVD compared with no chemotherapy (adjusted HR = 1.53, 95% confidence interval [CI] = 1.31 to 1.79), persisting at least 5 years postdiagnosis (adjusted HR5-<10 years = 1.85, 95% CI = 1.44 to 2.39; adjusted HR≥10 years = 1.83, 95% CI = 1.34 to 2.49). Cardiomyopathy and/or HF risks were elevated among women treated with anthracyclines and/or trastuzumab compared with no chemotherapy, especially for those aged younger than 65 years (adjusted HR20-54years = 2.97, 95% CI = 1.72 to 5.12; adjusted HR55-64years = 2.21, 95% CI = 1.52 to 3.21), differing for older women (adjusted HR≥65 years = 1.32, 95% CI = 0.97 to 1.78), and at least 5 years postdiagnosis (adjusted HR5-<10years = 1.89, 95% CI = 1.35 to 2.64; adjusted HR≥10 years = 2.21, 95% CI = 1.52 to 3.20). Anthracyclines and/or trastuzumab receipt was associated with increased ischemic heart disease risks after 5 or more years (adjusted HR5-<10years = 1.51, 95% CI = 1.06 to 2.14; adjusted HR≥10 years = 1.86, 95% CI = 1.18 to 2.93) with no clear age effects, and stroke risk (adjusted HR = 1.33, 95% CI = 1.05 to 1.69), which did not vary by time or age. There was some evidence of long-term cardiomyopathy and/or HF and ischemic heart disease risks with other chemotherapies. Among women aged younger than 65 treated with anthracyclines and/or trastuzumab, up to 16% developed CVD by 10 years (20-54 years = 6.91%; 55-64 years = 16.00%), driven by cardiomyopathy and/or HF (20-54 years = 3.90%; 55-64 years = 9.78%). We found increased long-term risks of cardiomyopathy and/or HF and ischemic heart disease among breast cancer survivors treated with anthracyclines and/or trastuzumab and increased cardiomyopathy and/or HF risk among women aged younger than 65 years.

Influence of Anatomic Locations of T1b Melanomas and Patient Age on Outcomes.

There are no guidelines on when to more strongly recommend sentinel lymph node biopsy (SLNB) for T1b melanomas. To examine whether anatomic locations of T1b melanomas and patient age influence metastases. We conducted a retrospective study using data from two hospitals in Los Angeles County from January 2010 through January 2020. Out of 620 patients with primary melanomas, 566 melanomas were staged based on the American Joint Committee on Cancer 8th edition melanoma staging. Forty-one were T1b, of which 13 were located on the face/ear/scalp and 28 were located elsewhere. T1b melanomas located on the face/ear/scalp had an increased risk of lymph node or distant metastasis compared with other anatomic sites (31% vs 3.6%, P=0.028). For all melanomas, the risk of lymph node or distant metastasis decreased with age of 64 years or greater (P&lt;0.001 and P=0.034). For T1b melanomas, the risk of distant metastasis increased with increasing age (P=0.047). Data were from a single county.&nbsp; Conclusion: T1b melanomas of the face/ear/scalp demonstrated a higher risk of lymph node or distant metastasis and may help guide the recommendation of SLNB, imaging, and surveillance. Younger patients may be more strongly considered for SLNB and older patients with T1b melanomas may warrant imaging.&nbsp; J Drugs Dermatol. 2024;23(5):306-310. doi:10.36849/JDD.7667.

Improving Adherence to Clinical Practice Guidelines for Managing Gastric Intestinal Metaplasia Among Gastroenterologists at a US Academic Institution.

Clinical guidelines reserve endoscopic surveillance after a gastric intestinal metaplasia (GIM) diagnosis for high-risk patients. However, it is unclear how closely guidelines are followed in clinical practice. We examined the effectiveness of a standardized protocol for the management of GIM among gastroenterologists at a US hospital. This was a preintervention and postintervention study, which included developing a protocol and education of gastroenterologists on GIM management. For the preintervention study, 50 patients with GIM were randomly selected from a histopathology database at the Houston VA Hospital between January 2016 and December 2019. For the postintervention study, we assessed change in GIM management in a cohort of 50 patients with GIM between April 2020 and January 2021 and surveyed 10 gastroenterologists. The durability of the intervention was assessed in a cohort of 50 GIM patients diagnosed between April 2021 and July 2021. In the preintervention cohort, GIM location was specified (antrum and corpus separated) in 11 patients (22%), and Helicobacter pylori testing was recommended in 11 of 26 patients (42%) without previous testing. Gastric mapping biopsies were recommended in 14% and surveillance endoscopy in 2%. In the postintervention cohort, gastric biopsy location was specified in 45 patients (90%, P <0.001) and H. pylori testing was recommended in 26 of 27 patients without prior testing (96%, P <0.001). Because gastric biopsy location was known in 90% of patients ( P <0.001), gastric mapping was not necessary, and surveillance endoscopy was recommended in 42% ( P <0.001). One year after the intervention, all metrics remained elevated compared with the preintervention cohort. GIM management guidelines are not consistently followed. A protocol for GIM management and education of gastroenterologists increased adherence to H. pylori testing and GIM surveillance recommendations.

Follow-up for human papillomavirus-related oropharynx cancer concentrated on unequal symptom change (FOCUS): Prospective patient-reported outcome collection.

Post-treatment surveillance recommendations for oropharyngeal cancer do not vary with p16 status despite the differences in outcomes. The optimal algorithm personalizing follow-up for these patients remains undefined. Here, we evaluate the feasibility and utility of incorporating electronic patient-reported outcomes (ePROs) and circulating tumor DNA (ctDNA) into routine surveillance for patients treated for p16+ oropharynx cancer. A prospective registry was developed in which ePROs and ctDNA were incorporated into routine surveillance among patients with oropharynx cancer. ePROs were emailed monthly for 1 year and blood HPV ctDNA testing was performed every 3-6 months. The primary objective was to assess patient compliance with ePRO-based surveillance with adequate compliance defined as ≥85% of patients completing monthly ePROs. Sensitivity, specificity, and positive/negative predictive values to detect recurrence were calculated for ePROs, HPV ctDNA, or the combination. Of 122 patients who initially expressed interest, 76 completed the electronic consent process and 44/76 (58%) were compliant with monthly surveys over 1 year; thus adequate compliance was not achieved. Technical difficulties associated with ePRO receipt through email largely limited participation. Provider feedback was significantly associated with heightened ePRO compliance. One hundred and six patients had ctDNA testing with a mean number of three tests per patient. Sensitivity to detect recurrence was 75% for the combination of ePROs and ctDNA. Despite lower than anticipated compliance with ePROs, our findings show promise for incorporation of HPV ctDNA into surveillance paradigms for HPV-related oropharynx cancer with suggestions of methods to optimize ePRO formats for personalized surveillance.

Trastuzumab-Induced Cardiotoxicity: When and How Much Should We Worry?

This review critically analyzes the incidence of trastuzumab-induced left ventricular systolic dysfunction and congestive heart failure (CHF), distinguishing between cases with and without prior anthracycline exposure. It highlights the fact that the elevated risk of trastuzumab-induced cardiotoxicity is closely associated with prior anthracycline exposure. In the absence of prior anthracycline exposure, the incidence rates of trastuzumab-induced cardiotoxicity, particularly CHF (ranging from 0% to 0.5%), are largely comparable with those reported in the general population, especially when reversibility is taken into account. Current cardiac surveillance recommendations during trastuzumab treatment have not yet adapted to the increasing adoption of nonanthracycline treatment strategies and the associated low risk of cardiotoxicity. We propose a refined monitoring protocol to reduce the frequency of cardiac evaluations for low-risk to moderate-risk patients, especially those receiving nonanthracycline treatments. By focusing on patients at high risk or those with prior anthracycline exposure, this strategy seeks to optimize the cost-effectiveness of cardiac care in oncology.

Screening and surveillance recommendations for central nervous system hemangioblastomas in pediatric patients with Von Hippel-Lindau disease

PurposeVon Hippel-Lindau (VHL) disease is an autosomal-dominantly inherited tumor predisposition syndrome. One of the most common tumors are central nervous system (CNS) hemangioblastomas. Recommendations on the initiation and continuation of the screening and surveillance program for CNS tumors in pediatric VHL patients are based on small case series and thus low evidence level. To derive more robust screening recommendations, we report on the largest monocentric pediatric cohort of VHL patients.MethodsWe performed a retrospective analysis on a pediatric cohort of 99 VHL patients consulted at our VHL center from 1992 to 2023. Clinical, surgical, genetic, and imaging data were collected and statistically analyzed.Results42 patients (50% male) developed CNS hemangioblastomas, of whom 18 patients (56% male) underwent hemangioblastoma surgery (mean age at first surgery: 14.9 ± 1.9 years; range 10.2–17). The first asymptomatic patient was operated on at the age of 13.2 years due to tumor progress. Truncating VHL mutation carriers had a significantly higher manifestation rate (HR = 3.7, 95% CI: 1.9–7.4, p < 0.0001) and surgery rate (HR = 3.3, 95% CI: 1.2–8.9, p = 0.02) compared with missense mutation carriers.ConclusionWe recommend starting MRI imaging at the age of 12 years with examination intervals every (1-) 2 years depending on CNS involvement. Special attention should be paid to patients with truncating variants. Affected families should be educated regularly on potential tumor-associated symptoms to enable timely MRI imaging and eventually intervention, as CNS hemangioblastoma may develop before screening begins.German clinical trials Register registration numberDRKS00029553, date of registration 08/16/2022, retrospectively registered.

Imaging findings of children with PTEN-related hamartoma tumor syndrome: a 20-year multicentric pediatric cohort.

PTEN-related hamartoma tumor syndrome results from a mutation in the PTEN gene located at 10q23.31. This syndrome represents a spectrum of different phenotypes of variable expressions, now recognized as part of the same condition. Patients with this mutation have an increased risk of developing a wide range of findings, including malignancies. Although widely described in adults, there are no large series describing the imaging findings in patients before adulthood. Knowledge of the findings seen in children and adolescents with PTEN-related hamartoma tumor syndrome can help guide further management and improve surveillance recommendations. To describe the spectrum of imaging abnormalities in pediatric patients with PTEN-related hamartoma tumor syndrome. We performed a retrospective, cross-sectional, multicenter study conducted between January 2000 and October 2021 in three tertiary pediatric institutions evaluating the imaging findings in children and adolescents (≤ 18 years) with confirmed diagnoses of a PTEN mutation. For each patient, the imaging findings, histopathology reports, and at least a 2-year follow-up of clinical outcomes for non-operative cases were documented. The cohort included 78 children (37 girls), with a mean age at diagnosis of 7.5 years (range 0 days to 18 years). Benign brain findings included enlarged Virchow-Robin perivascular spaces, white matter changes, developmental venous anomalies, and cerebellar hamartomas. Benign thyroid findings were common, but 5/45 (11.1%) with thyroid abnormalities had a malignant nodule. Soft tissue adipocytic tumors, GI/GU polyps, other soft tissue abnormalities, along with vascular anomalies in various anatomic locations were common. Brain abnormalities, benign non-vascular soft tissue abnormalities, and vascular anomalies are commonly seen in children and adolescents with PTEN-related hamartoma tumor syndrome. However, malignancies involving the thyroid gland are not uncommon. Familiarity with the phenotype of PTEN-related hamartoma tumor syndrome in the pediatric population can improve diagnosis and prompt appropriate clinical surveillance of abnormal findings that warrant further management.

Comparative evaluation of a language model and human specialists in the application of European guidelines for the management of inflammatory bowel diseases and malignancies.

Society guidelines on colorectal dysplasia screening, surveillance, and endoscopic management in inflammatory bowel disease (IBD) are complex, and physician adherence to them is suboptimal. We aimed to evaluate the use of ChatGPT, a large language model, in generating accurate guideline-based recommendations for colorectal dysplasia screening, surveillance, and endoscopic management in IBD in line with European Crohn's and Colitis Organization (ECCO) guidelines. 30 clinical scenarios in the form of free text were prepared and presented to three separate sessions of ChatGPT and to eight gastroenterologists (four IBD specialists and four non-IBD gastroenterologists). Two additional IBD specialists subsequently assessed all responses provided by ChatGPT and the eight gastroenterologists, judging their accuracy according to ECCO guidelines. ChatGPT had a mean correct response rate of 87.8%. Among the eight gastroenterologists, the mean correct response rates were 85.8% for IBD experts and 89.2% for non-IBD experts. No statistically significant differences in accuracy were observed between ChatGPT and all gastroenterologists (P=0.95), or between ChatGPT and the IBD experts and non-IBD expert gastroenterologists, respectively (P=0.82). This study highlights the potential of language models in enhancing guideline adherence regarding colorectal dysplasia in IBD. Further investigation of additional resources and prospective evaluation in real-world settings are warranted.
