Knowledge and attitude on childhood cancer survivorship among healthcare trainees: a multicentre study from India.

BACKGROUND: The proportion of childhood cancer survivors (CCS) in low/middle-income countries (LMICs) is rising. CCS often develop several physical and psycho-social long-term adverse effects, with unique healthcare needs. Primary healthcare providers (primary care physicians (PCPs)), especially in LMICs, are often not equipped to handle survivorship care. This study aimed to assess knowledge, and attitude among trainee healthcare providers concerning major issues of paediatric survivorship care. METHODS: A multi-centre, cross-sectional, questionnaire-based study was conducted among nursing and medical undergraduate students, and postgraduate medical residents across three tertiary-care teaching hospitals in India-All India Institute of Medical Sciences, New Delhi; Jawaharlal Institute of Postgraduate Medical Education and Research, Puducherry; and Maulana Azad Medical College, New Delhi. A questionnaire with total of 24 questions (14 knowledge-based and 10 attitude-based) was finalised after validation by expert review and piloting. The major domains covered in the questionnaire included knowledge and attitude regarding long-term adverse effects and psychosocial, employment-related issues faced by the survivors. It was administered to the study participants electronically. The knowledge-based questions had true/false responses (scored as 0 or 1 if incorrect or correct, respectively). Attitude-based questions were scored as 5-point Likert scale. RESULTS: Total 898 responses were collected (median age: 21 years, 64% (576/898) female). Among the respondents, 44% were undergraduate medical students, 42% were nursing students and 14% were postgraduate medical residents. The mean (SD) of knowledge score was 8.72 (2.04) (out of 14). On multivariable analysis, only discipline of training predicted knowledge scores regarding survivorship care. Postgraduate medical residents (9.08) as well as undergraduate medical students (8.85), had significantly higher mean knowledge scores than nursing students (8.47) (p=0.004).Two questions were answered incorrectly by the majority; children and siblings of CCS need additional genetic screening (79% incorrectly answered true), and CCS face intimacy issues in relation to normal sexual functioning (59% incorrectly answered false).Nearly half (48%) of respondents believed that their knowledge of cancer survivorship issues was inadequate. Majority of respondents (84%) suggested that oncologists should handle long-term survivorship care rather than PCPs. CONCLUSION: Trainee healthcare providers in India reported inadequate knowledge regarding survivorship care. Improving awareness by incorporating survivorship in teaching curriculum is imperative to equip future PCPs to provide survivorship care across the country.

Geriatric assessment-identified impairments and frailty in adults with cancer younger than 65: An opportunity to optimize oncology care.

INTRODUCTION: Frailty, a state of increased vulnerability to stressors due to aging or treatment-related accelerated aging, is associated with declines in physical, cognitive and/or social functioning, and quality of life for cancer survivors. For survivors aged <65 years, little is known about frailty status and associated impairments to inform intervention. We aimed to evaluate the prevalence of frailty and contributing geriatric assessment (GA)-identified impairments in adults aged <65 versus ≥65 years with cancer. MATERIALS AND METHODS: This study is a secondary analysis of clinical trial data (NCT04852575). Participants were starting a new line of systemic therapy at a community-based oncology private practice. Before starting treatment, participants completed an online patient-reported GA and the Physical Activity (PA) Vital Sign questionnaire. Frailty score and category were derived from GA using a validated deficit accumulation model: frail (>0.35), pre-frail (0.2-0.35), or robust (0-0.2). PA mins/week were calculated, and participants were coded as either meeting/not-meeting guidelines (≥90 min/week). We used Spearman (ρ) correlation to examine the association between age and frailty score and chi-squared/Fisher's-exact or ANOVA/Kruskal-Wallis statistic to compare frailty and PA outcomes between age groups. RESULTS: Participants (n = 96) were predominantly female (62%), Caucasian (68%), beginning first-line systemic therapy (69%), and 1.75 months post-diagnosis (median). Most had stage III to IV disease (66%). Common cancer types included breast (34%), gastrointestinal (23%), and hematologic (15%). Among participants <65, 46.8% were frail or pre-frail compared to 38.7% of those ≥65. There was no association between age and frailty score (ρ = 0.01, p = 0.91). Between age groups, there was no significant difference in frailty score (p = 0.95), the prevalence of frailty (p = 0.68), number of GA impairments (p = 0.33), or the proportion meeting PA guidelines (p = 0.72). However, older adults had more comorbid conditions (p = 0.03) and younger adults had non-significant but clinically relevant differences in functional ability, falls, and PA level. DISCUSSION: In our cohort, the prevalence of frailty was similar among adults with cancer <65 when compared to those older than 65, however, types of GA impairments differed. These results suggest GA and the associated frailty index could be useful to identify needs for intervention and inform clinical decisions during cancer treatment regardless of age. Additional research is needed to confirm our findings.

Intestinal Intussusception Complicating an Undiagnosed Burkitt Lymphoma in a Pediatric Arab Patient.

Burkitt's lymphoma (BL) is considered an aggressive form of a non-Hodgkin B-cell lymphoma, representing less than 5% of all pediatric malignancies and 30% of pediatric lymphomas. However, intestinal BL may present as a lead point, causing intussusception. Surgery continues to be the gold standard for the treatment and identification of localized tumors to ensure complete removal with proper margin. In this report, we describe a hidden BL presenting as intestinal intussusception in an eight-year-old Arab boy. A computed tomography (CT) scan of the abdomen revealed an ileoileal intussusception with multiple enlarged lymph nodes. The report discusses the role of histopathology, supported by immunohistochemistry studies, in establishing the diagnosis. It also covers the significance of proper laparoscopic surgery and chemotherapy in the management of this child.

Botulinum toxin: a new differential diagnosis for a lytic bone lesion.

BACKGROUND: Botulinum toxin, produced by the Gram-positive anaerobe Clostridium botulinum, is composed of seven antigenic subtypes (A, B, C, D, E, F, and G). Currently, only Botulinum toxin type A, commonly referred to as "Botox," is approved for clinical use, given its relatively safe clinical profile. Botulinum toxin type A has a wide range of therapeutic indications, including treatment for dystonia, migraine headache, neurogenic bladder, and large muscle spastic disorders. However, the toxin is most widely known for its cosmetic effects in treating wrinkles and facial lines. CASE PRESENTATION: This article describes a 62-year-old Caucasian female who presented for investigation and workup of an isolated lytic lesion of her frontal bone a few weeks after administration of botulinum toxin injection into the corresponding site in the frontalis muscle. This presented as a large, palpable, painless forehead lump causing significant psychological distress. After no neoplastic cause for the lesion was found and histopathology was performed, our researchers concluded that the most likely explanation was that the bony lytic lesion resulted from inadvertent injection of the "Botox" neurotoxin through the intended target muscle and into the cortex of the underlying bone. CONCLUSIONS: Our search of the literature failed to identify any previous cases of this occurring. However, as the popularity of this cosmetic procedure only increases, we believe that this represents an important possible differential for isolated lytic lesion after administration of "Botox" injection.

Exploring the current landscape of single-cell RNA sequencing applications in gastric cancer research.

Gastric cancer (GC) represents a major global health burden and is responsible for a significant number of cancer-related fatalities. Its complex nature, characterized by heterogeneity and aggressive behaviour, poses considerable challenges for effective diagnosis and treatment. Single-cell RNA sequencing (scRNA-seq) has emerged as an important technique, offering unprecedented precision and depth in gene expression profiling at the cellular level. By facilitating the identification of distinct cell populations, rare cells and dynamic transcriptional changes within GC, scRNA-seq has yielded valuable insights into tumour progression and potential therapeutic targets. Moreover, this technology has significantly improved our comprehension of the tumour microenvironment (TME) and its intricate interplay with immune cells, thereby opening avenues for targeted therapeutic strategies. Nonetheless, certain obstacles, including tumour heterogeneity and technical limitations, persist in the field. Current endeavours are dedicated to refining protocols and computational tools to surmount these challenges. In this narrative review, we explore the significance of scRNA-seq in GC, emphasizing its advantages, challenges and potential applications in unravelling tumour heterogeneity and identifying promising therapeutic targets. Additionally, we discuss recent developments, ongoing efforts to overcome these challenges, and future prospects. Although further enhancements are required, scRNA-seq has already provided valuable insights into GC and holds promise for advancing biomedical research and clinical practice.

Cancer screening with multicancer detection tests: A translational science review.

Multicancer detection (MCD) tests use a single, easily obtainable biospecimen, such as blood, to screen for more than one cancer concurrently. MCD tests can potentially be used to improve early cancer detection, including cancers that currently lack effective screening methods. However, these tests have unknown and unquantified benefits and harms. MCD tests differ from conventional cancer screening tests in that the organ responsible for a positive test is unknown, and a broad diagnostic workup may be necessary to confirm the location and type of underlying cancer. Among two prospective studies involving greater than 16,000 individuals, MCD tests identified those who had some cancers without currently recommended screening tests, including pancreas, ovary, liver, uterus, small intestine, oropharyngeal, bone, thyroid, and hematologic malignancies, at early stages. Reported MCD test sensitivities range from 27% to 95% but differ by organ and are lower for early stage cancers, for which treatment toxicity would be lowest and the potential for cure might be highest. False reassurance from a negative MCD result may reduce screening adherence, risking a loss in proven public health benefits from standard-of-care screening. Prospective clinical trials are needed to address uncertainties about MCD accuracy to detect different cancers in asymptomatic individuals, whether these tests can detect cancer sufficiently early for effective treatment and mortality reduction, the degree to which these tests may contribute to cancer overdiagnosis and overtreatment, whether MCD tests work equally well across all populations, and the appropriate diagnostic evaluation and follow-up for patients with a positive test.

Inconsistency in steroid use as antiemetics in clinical trial protocols involving immune checkpoint inhibitors combined with chemotherapy.

OBJECTIVES: This study aims to investigate the use of steroids as antiemetics in clinical trials involving immune checkpoint inhibitors with chemotherapy. METHODS: Focusing on phase III trials registered before August 2023, it evaluated the consistency of steroid use guidelines. RESULTS: Out of 3452 trials screened, 44 were selected for in-depth review. The findings indicate a considerable variation: 13 trials did not specify the use of antiemetics, while 31 provided criteria for antiemetics, with 13 conforming to local standards, six to international guidelines, and five allowing either. Seven trials recommended effective antiemetics without detailed criteria. This inconsistency led to a range of steroid dosages, with only 11 trials advocating for minimizing or avoiding steroids for antiemetic purposes. CONCLUSION: The research highlights the lack of uniformity in antiemetic steroid use in trials, reflecting diverse clinical practices and underscoring the need for further research to understand the implications on treatment outcomes.

Why do second-cycle medical students choose oncology? A literature overview.

INTRODUCTION: Given the current global cancer epidemic across the world, the need for healthcare professionals in this field is crucial. Little is known about the factors that drive medical students toward oncology. METHOD: We conducted a systematic review of the literature (from 1980 to the present), using several search equations and selecting original articles written in English based on qualitative or quantitative surveys, to understand what motivates medical students to choose oncology. RESULTS: We identified only seven articles that reported quantitative surveys; no qualitative surveys were found. These seven surveys are composed of closed-ended questions and are pragmatic questionnaires based on field knowledge, but without an underlying theory. These studies most often interrogate students already oriented towards oncology. The following five concepts associated with the choice of oncology had the highest recurrence among these seven surveys, which had been conducted in different countries and at various times: interest in cancer management, initiation of the specialty during the 2nd cycle, job opportunities, low working hours, and quality of life. DISCUSSION: The literature on this topic is particularly scarce. No qualitative studies have been published in the English language. The limited data in the literature do not allow us to fully comprehend the problem.

Appraisal of hydatidiform mole incidence and registration rates in Ireland following the establishment of a National Gestational Trophoblastic Disease Registry.

AIMS: This study aimed to re-evaluate the incidence of hydatidiform mole (HM) and determine gestational trophoblastic disease (GTD) registration rates in Ireland following the establishment of the National GTD Registry in 2017. METHODS: We performed a 3-year retrospective audit of HM cases (January 2017 to December 2019) reported in our centre. In 2019, we surveyed Irish pathology laboratories to determine the number of HMs diagnosed nationally and compared this data to that recorded in the National GTD Registry. Additionally, we compared both local and national HM incidence rates to those reported internationally. RESULTS: In the 3-year local audit, we identified 87 HMs among 1856 products of conception (POCs) providing a local HM incidence rate of 3.92 per 1000 births. The 1-year pathology survey recorded 170 HMs in 6008 POCs, yielding a national incidence rate of 2.86 per 1000 births. Importantly, the local HM incidence rate exceeded the national incidence rate by 37% and the local partial HM incidence (1 in 296 births) was 64% higher than the nationally incidence rate (1 in 484 births). Notably, 42% of the HM and atypical POCs diagnosed nationally were not reported to the National GTD Registry. CONCLUSIONS: Our study reveals increased HM incidence rates both locally and nationally compared with previous Irish studies. The higher local PHM incidence may reflect more limited access to ploidy analysis in other pathology laboratories nationally. Significantly, almost half of the women with diagnosed or suspected HM were not registered with the National GTD Centre.

Breast cancer survivors suffering from lymphedema: What really do affect to corporeality/body image? A qualitative study.

Breast cancer-related lymphedema is currently one of the most serious complications that most affect the quality of life of women undergoing breast cancer. The aim of this study was to explore in-depth the experience of women who suffer from lymphoedema after breast cancer and how does this condition affect corporeality, with no judgements. For this purpose, a qualitative methodology was followed. In-depth interviews, interviewer's field notes and participants' letters were used for data collection. The participants were twenty Spanish women with lymphoedema after overcome a breast cancer in the past. Healthcare specialists with experience in the topic were also included. Results showed 2 main categories: "From cancer to lymphedema, another disease another disease" and "Potential for transition and transformation towards a new way of life". As a conclusion, the difficulty in accessing adequate treatment, the need for greater awareness of lymphedema and the importance of the emotional and psychological dimension of this chronic disease. Highlighting the attitudes that these women develop for self-care and the concept of new corporeality. After breast cancer, women with lymphedema experience a drastic change that affects all areas of their lives. The adaptation process, and the search for resources and aid, play a fundamental role in overcoming this process.

Immunotherapy for the treatment of biliary tract cancer: an evolving landscape.

Biliary tract cancers (BTCs), consisting of intrahepatic and extrahepatic cholangiocarcinoma and gallbladder cancer, are an aggressive, heterogeneous malignancy. They are most often diagnosed in the locally advanced or metastatic setting, at which point treatment consists of systemic therapy or best supportive care. Our understanding of the tumor microenvironment and the molecular classification has led to the identification of targetable mutations, such as isocitrate dehydrogenase 1 and fibroblast growth factor receptor 2. Despite the identification of these genomic alterations, until recently, little advancement had been made in the first-line setting for advanced BTC. While immunotherapy (IO) has revolutionized the treatment of many malignancies, the use of IO in BTC had yielded limited results prior to TOPAZ-1. In this review, we discuss the systemic therapeutic advances for BTC over the past decade, the rationale for immunotherapy in BTC, prior trials utilizing IO in BTC, and current and emerging immune-based therapeutic options. We further analyze the culmination of these advances, which resulted in the approval of durvalumab with gemcitabine and cisplatin for the first-line treatment of BTC per TOPAZ-1. We also discuss the results of KEYNOTE-966, which similarly reported improved clinical outcomes with the use of pembrolizumab in combination with gemcitabine and cisplatin.

Electroporación irreversible: ampliando las fronteras de la ablación / Irreversible electroporation: Beyond the limits of tumor ablation

La electroporación irreversible o IRE (irreversible electroporation) es una técnica de ablación tumoral no térmica basada en la aplicación de pulsos eléctricos de alto voltaje entre pares de agujas insertadas alrededor de un tumor. La corriente generada favorece la creación de nanoporos en la membrana plasmática, desencadenando la apoptosis. Por ello, la IRE puede utilizarse de manera segura en localizaciones cercanas a estructuras vasculares delicadas, contraindicadas para el resto de técnicas termoablativas. Actualmente la IRE se emplea con éxito para la ablación de tumores en páncreas, riñón e hígado y, de manera muy extendida, como opción terapéutica focal para el cáncer de próstata. La necesidad de un manejo anestésico específico y la colocación precisa y en paralelo de múltiples agujas implican un alto nivel de complejidad, siendo necesaria una gran experiencia del equipo intervencionista. No obstante, se trata de una técnica muy prometedora con una gran capacidad inmunológica sistémica que puede provocar un efecto a distancia del tumor tratado (efecto abscopal).(AU)

Irreversible electroporation (IRE) is a non-thermal tumor ablation technique. High-voltage electrical pulses are applied between pairs of electrodes inserted around and/or inside a tumor. The generated electric current induces the creation of nanopores in the cell membrane, triggering apoptosis. As a result, IRE can be safely used in areas near delicate vascular structures where other thermal ablation methods are contraindicated. Currently, IRE has demonstrated to be a successful ablation technique for pancreatic, renal, and liver tumors and is widely used as a focal therapeutic option for prostate cancer. The need for specific anesthetic management and accurate parallel placement of multiple electrodes entails a high level of complexity and great expertise from the interventional team is required. Nevertheless, IRE is a very promising technique with a remarkable systemic immunological capability and may impact on distant metastases (abscopal effect).(AU)

Implementation of the REFLECT Communication Curriculum for Clinical Oncology Graduate Medical Education.

Background: Communication and interpersonal skills are essential medical components of oncology patient care. Patients and families rely on physicians for treatment, expertise, guidance, hope, meaning, and compassion throughout a life-threatening illness. A provider's inability to empathize with patients is linked to physician-related fatigue and burnout. Because oncology training programs focus on teaching evidence-based medicine and clinical acumen, little time may be dedicated to professional development and acquisition of interactive skills. Traditional communication courses typically include two components: formal, knowledge-based learning skills, which are gained from didactic lectures, and role-playing, which usually occurs in small groups. We report the implementation of a novel longitudinal communication curriculum for trainees in Oncology. Materials and Methods: At a single-center institution, an innovative communication curriculum titled "REFLECT" (Respect, Empathy, Facilitate Effective Communication, Listen, Elicit Information, Compassion, and Teach Others) was implemented for radiation oncology residents and medical oncology fellows to improve and refine physician/patient interactions. All oncology specialty residents and fellows were eligible to participate in this communication curriculum. The curriculum emphasized a reflective process to guide trainees through challenging scenarios. Results: Since October 2018, this comprehensive course consisted of quarterly (four hour) workshops comprising assigned reading, knowledge assessments, didactic lectures, expert guest lecturers, standardized patient simulations, role-playing, patient/expert panels, coaching, reflective writing, and debriefing/feedback sessions. The curriculum provided longitudinal communication training integrated with the learners' daily physician/patient encounters rather than occasional isolated experiences. Fifteen workshops have been completed. Each focused on navigating challenging situations with patients, loved ones, or colleagues. Conclusions: Future directions of the curriculum will entail improving the communication skills of oncology trainees and gathering communication improvement data to assess the program's success formally.

Integrative Oncology Approaches to Supporting Immune Checkpoint Inhibitor Treatment of Solid Tumours.

PURPOSE OF REVIEW: The goal of this review was to examine the role and practical applications of integrative oncology strategies in supporting immune checkpoint inhibitor (ICI) treatment of adult solid tumours. RECENT FINDINGS: Beyond tumour-intrinsic factors, several patient-associated factors affect ICI response, including germline genetics, systemic inflammation, the gut microbiota, and diet. Current promising supportive interventions include a Mediterranean-style diet with over 20 g of fibre, regular exercise, use of live biotherapeutics, minimisation of PPI and antibiotic use, and ensuring vitamin D repletion, with many other integrative oncology approaches under study. Caution around medical cannabis use in patients on ICIs is advised due to previously documented adverse impact on overall survival, while VAE (Viscum album extract) therapy studies have not highlighted any safety concerns so far. With expanding ICI use, it is important to investigate and apply low-cost integrative oncology strategies to support better treatment outcomes and minimise adverse events. Further research may lead to pre-treatment assessment of both tumour and patient-associated biomarkers and personalised multimodal prehabilitation care plans, as well as on-treatment support with targeted nutrition, physical activity, and supplementation regimes, including both systemic inflammation and gut microbiome modulating strategies. Given the emerging understanding of chronic stress impact on ICI treatment outcomes, mind-body approaches require further investigation.

Assessing the methodological strengths and limitations of the Spanish Society of Medical Oncology (SEOM) guidelines: a critical appraisal using AGREE II and AGREE-REX tool

Background The Spanish Society of Medical Oncology (SEOM) has provided open-access guidelines for cancer since 2014. However, no independent assessment of their quality has been conducted to date. This study aimed to critically evaluate the quality of SEOM guidelines on cancer treatment. Methods Appraisal of Guidelines for Research and Evaluation II (AGREE II) and AGREE-REX tool was used to evaluate the qualities of the guidelines. Results We assessed 33 guidelines, with 84.8% rated as “high quality”. The highest median standardized scores (96.3) were observed in the domain “clarity of presentation”, whereas “applicability” was distinctively low (31.4), with only one guideline scoring above 60%. SEOM guidelines did not include the views and preferences of the target population, nor did specify updating methods. Conclusions Although developed with acceptable methodological rigor, SEOM guidelines could be improved in the future, particularly in terms of clinical applicability and patient perspectives (AU)
