Venous thromboembolism prevention program implementation in a community oncology practice: a cohort study

While national guidelines recommend Venous Thromboembolism (VTE) risk assessment in cancer outpatients and consideration of pharmacologic prophylaxis in high-risk patients, prophylaxis rates are low in community oncology practices. A successful model for guideline implementation (the Vermont Model, VM) is validated in an academic tertiary oncology setting. We undertook an implementation study to determine the success of this model in a multi-site community oncology practice. The study objectives were to: 1) adapt the VM to the community practice setting; 2) implement the adapted VM into practice; and 3) evaluate clinical and implementation outcomes. The study was carried out in three phases: (1) Pre-implementation, a multidisciplinary team addressed the need to adapt the VM to the local context including electronic medical record (EMR) optimisation and clinician education; (2) implementation of the strategies adapted to the local context, informed by VM and adapted based on stakeholder feedback; (3) prospective evaluation of clinical and implementation outcomes at six months after implementation. Following creation of a comprehensive initiation roadmap for the adaptation of VM program to the community practice, 302 cancer outpatients initiating new treatment met inclusion criteria over a 6 month implementation period. VTE risk education was provided to 100% of patients, and 98% (296) of patients received a VTE risk assessment. Of 52 patients (18%) who scored as high risk based on a modified Khorana (Protecht) score, 14 (27%) initiated prophylaxis. Barriers to program adaptation included EMR optimization challenges and practice-level responsibility assignment, time constraints, concern about potential drug interactions, and financial & insurance issues. Implementation of a multidisciplinary VTE prevention model in the community-based oncology setting successfully increased VTE education and risk assessment rates. AC prophylaxis rates were modestly increased, highlighting the need to understand and address barriers to anticoagulant prophylaxis prescribing in this setting.

Real-world treatment costs of first-line treatment for metastatic colorectal cancer: a survey of the JCOG colorectal cancer study group.

Although treatment outcomes for metastatic colorectal cancer (mCRC) have dramatically improved over the past few decades, drug costs have also significantly increased. This study aimed to investigate which first-line treatment regimens for mCRC are actually used (frequency) in Japanese practice and at what cost. We collected data on patients with mCRC who received first-line treatment at 37 institutions of the Japan Clinical Oncology Group Colorectal Cancer Study Group from July 2021 to June 2022, and calculated the cost of regimens. The cost per month of each regimen was estimated based on standard usage, assuming a patient with a weight of 70kg and a body surface area of 1.8m2. We categorized the regimens into very high-cost (≥1 000 000 Japanese yen [JPY]/month), high-cost (≥500 000 JPY/month), and others (<500 000 JPY/month). The study included 1880 participants, 24% of whom were≥75years. Molecular targeted containing regimens were received by 78% of the patients. The most frequently used regimen was the doublet regimen (fluoropyrimidine with either oxaliplatin or irinotecan) plus bevacizumab (43%), followed by doublet plus cetuximab or panitumumab (21%). The cost of molecular targeted drugs-containing regimens (ranging from 85 406 to 843 602 JPY/month) is much higher than that of only cytotoxic drug regimens (ranging from 17 672 to 51 004 JPY/month). About 16% received high-cost treatments that included panitumumab-containing regimens and pembrolizumab (17% of patients aged ≤74years and 11% of patients aged ≥75years). About 16% of mCRC patients received first-line treatment with regimens costing >500 000JPY/month, and molecular targeted drugs being the main drivers of cost.

Oncology researchers’ and clinicians’ perceptions of complementary, alternative, and integrative medicine: an international, cross-sectional survey

BackgroundComplementary, alternative, and integrative medicine (CAIM) has become an increasingly popular supportive therapy option for patients with cancer. The objective of this study was to investigate how researchers and clinicians in the oncology field perceive CAIM.MethodsWe conducted an online, anonymous, cross-sectional survey for researchers and clinicians who have published their work in oncology journals that are indexed in MEDLINE. The link to the survey was sent to 47, 991 researchers and clinicians whose contact information was extracted from their publications. The survey included various multiple-choice questions, and one open-ended question at the end to allow for any additional comments.Results751 respondents completed the survey, and they mostly identified themselves as researchers (n = 329, 45.13%), or as both researchers and clinicians (n = 332, 45.45%) in the field of oncology. Over half of the respondents perceive mind–body therapies (n = 354, 54.97%) to be the most promising CAIM category with regards to the prevention, treatment, and/or management of diseases related to oncology, and many respondents agreed that most CAIM therapies are safe (n = 218, 37.39%), and that clinicians should receive training on CAIM therapies via formal (n = 225, 38.59%) and supplemental education (n = 290, 49.83%). However, many respondents were unsure when asked if most CAIM therapies are effective (n = 202, 34.77%).ConclusionsThe findings from this study demonstrated great current interest in the use of CAIM in oncology. This information can serve as a foundation for conducting additional research and creating customized educational materials for researchers and clinicians in oncology.

Prevention and management of radiotherapy-related toxicities in gynecological malignancies. Position paper on behalf of AIRO (Italian Association of Radiotherapy and Clinical Oncology)

Multi-modal therapies for gynecological cancers management may determine a wide range of side effects which depend on therapy-related factors and patient characteristics and comorbidities. Curative or adjuvant pelvic radiotherapy is linked with acute and late toxicity due to irradiation of organs at risk, as small and large bowel, rectum, bladder, pelvic bone, vagina and bone marrow. Successful toxicity management varies with its severity, Radiation Centre practice and experience and skills of radiation oncologists. This position paper was designed by the Italian Association of Radiation and Clinical Oncology Gynecology Study Group to provide radiation oncologists with evidence-based strategies to prevent and manage acute and late toxicities and follow-up recommendations for gynecological cancer patients submitted radiotherapy. Six workgroups of radiation oncologists with over 5 years of experience in gynecologic cancers were setup to investigate radiotherapy-related toxicities. For each topic, PubMed database was searched for relevant English language papers from January 2005 to December 2022. Titles and abstracts of results were checked to verify suitability for the document. Reference lists of selected studies and review papers were added if pertinent. Data on incidence, etiopathogenesis, prevention, treatment and follow-up of acute and late side effects for each organ at risk are presented and discussed.

Survivorship program including long-term toxicities and quality-of-life development over 10 years in a randomized trial in operable stage III non-small-cell lung cancer (ESPATUE).

Over 40% stage-III non-small-cell lung cancer (NSCLC) patients (pts) experience 5-year survival following multimodality treatment. Nevertheless, little is known about relevant late toxicities and quality-of-life (QoL) in the further long-term follow-up. Therefore, we invited pts from our randomized phase-III trial (Eberhardt et al., Journal of Clinical Oncology 2015) after 10 years from diagnosis to participate within a structured survivorship program (SSP) including follow-up imaging, laboratory parameters, cardio-pulmonary investigations, long-term toxicity evaluations and QoL questionnaires. Of 246 pts initially accrued, 161 were considered potentially resectable following the induction therapy and were randomized (80 to arm A: definitive chemoradiation; 81 to arm B: definitive surgery; 85 not randomized for different reasons; group C). 31 from 37 pts still alive after 10 years agreed to the SSP (13 in A; 12 in B; 6 in C). Clinically relevant long-term toxicities (grade 3 and 4) were rarely observed with no signal favoring any of the randomization arms. Furthermore, available data from the global QoL analysis did not show a signal favoring any definitive locoregional approach (Mean QoL in SSP A pts: 56.41/100, B pts: 64.39/100) and no late decline in comparison to baseline and early 1-year follow-up. This is the first comprehensive SSP of very late survival follow-up reported in stage-III NSCLC treated within a randomized multimodality trial and it may serve as important baseline information for physicians and pts deciding for a locoregional treatment option.

A novel step towards the heterologous biosynthesis of paclitaxel: Characterization of T1βOH taxane hydroxylase

In the quest for innovative cancer therapeutics, paclitaxel remains a cornerstone in clinical oncology. However, its complex biosynthetic pathway, particularly the intricate oxygenation steps, has remained a puzzle in the decades following the characterization of the last taxane hydroxylase. The high divergence and promiscuity of enzymes involved have posed significant challenges. In this study, we adopted an innovative approach, combining in silico methods and functional gene analysis, to shed light on this elusive pathway. Our molecular docking investigations using a library of potential ligands uncovered TB574 as a potential missing enzyme in the paclitaxel biosynthetic pathway, demonstrating auspicious interactions. Complementary in vivo assays utilizing engineered S. cerevisiae strains as novel microbial cell factory consortia not only validated TB574's critical role in forging the elusive paclitaxel intermediate, T5αAc-1β,10β-diol, but also achieved the biosynthesis of paclitaxel precursors at an unprecedented yield including T5αAc-1β,10β-diol with approximately 40 mg/L. This achievement is highly promising, offering a new direction for further exploration of a novel metabolic engineering approaches using microbial consortia. In conclusion, our study not only furthers study the roles of previously uncharacterized enzymes in paclitaxel biosynthesis but also forges a path for pioneering advancements in the complete understanding of paclitaxel biosynthesis and its heterologous production. The characterization of T1βOH underscores a significant leap forward for future advancements in paclitaxel production using heterologous systems to improve cancer treatment and pharmaceutical production, thereby holding immense promise for enhancing the efficacy of cancer therapies and the efficiency of pharmaceutical manufacturing.

Towards Understanding Tumour Colonisation by Probiotic Bacterium E. coli Nissle 1917.

The last decade has seen a rapid increase in studies utilising a genetically modified probiotic, Escherichia coli Nissle 1917 (EcN), as a chassis for cancer treatment and detection. This approach relies on the ability of EcN to home to and selectively colonise tumours over normal tissue, a characteristic common to some bacteria that is thought to result from the low-oxygen, nutrient-rich and immune-privileged niche the tumour provides. Pre-clinical studies have used genetically modified EcN to deliver therapeutic payloads that show efficacy in reducing tumour burden as a result of high-tumour and low off-target colonisation. Most recently, the EcN chassis has been expanded into an effective tumour-detection tool. These advances provide strong justification for the movement of genetically modified EcN into clinical oncology trials. What is currently unknown in the field is a deep mechanistic understanding of how EcN distributes to and localises within tumours. This review summarises the existing EcN literature, with the inclusion of research undertaken with other tumour-homing and pathogenic bacteria, to provide insights into possible mechanisms of EcN tumour homing for future validation. Understanding exactly how and why EcN colonises neoplastic tissue will inform the design and testing of the next generation of EcN chassis strains to address biosafety and containment concerns and optimise the detection and treatment of cancer.

Sodium diethyldithiocarbamate trihydrate: an effective and selective compound for hematological malignancies.

Myeloid leukemias and lymphomas are among the most common and well-studied hematological malignancies. However, due to the aggressiveness and rapid progression of certain subtypes, treating these diseases remains a challenge. Considering the promising results of diethyldithiocarbamates in preclinical and clinical oncology trials, this study aimed to investigate the potential of sodium diethyldithiocarbamate trihydrate (DETC) as a prototype for developing new drugs to treat hematological malignancies. In silico analysis using SwissADME was conducted to evaluate the physicochemical characteristics and pharmacokinetic properties of DETC. An in vitro investigation utilizing the MTT assay assessed the cytotoxic effects of DETC on neoplastic and non-neoplastic cell lines. Selectivity was determined using a selectivity index and a hemolysis assay, while the mechanism of cell death in neoplastic cell lines was examined through flow cytometry analysis of pro-apoptotic and anti-apoptotic protein levels. The results demonstrated that the physicochemical characteristics of DETC are suitable for oral administration. Furthermore, the compound showed promising cytotoxic activity against human myeloid leukemia (K562) and Burkitt's lymphoma (Daudi) cell lines, with high selectivity for neoplastic cells over non-neoplastic cells of the bone marrow microenvironment (HS-5 cell line). Moreover, hemolysis was observed only at very high concentrations. The cytotoxicity mechanism of DETC against both neoplastic cell lines involved cell cycle arrest and the production of reactive oxygen species. In K562 cells, cell death was induced via apoptosis. Additional experiments are needed to confirm the exact mechanism of cell death in Daudi Burkitt's lymphoma cells.

Personalized medicine: Clinical oncology on molecular view of treatment.

Cancer, the second leading global cause of death, impacts both physically and emotionally. Conventional treatments such as surgeries, chemotherapy, and radiotherapy have adverse effects, driving the need for more precise approaches. Precision medicine enables more targeted treatments. Genetic mapping, alongside other molecular biology approaches, identifies specific genes, contributing to accurate prognoses. The review addresses, in clinical use, a molecular perspective on treatment. Biomarkers like alpha-fetoprotein, beta-human chorionic gonadotropin, 5-hydroxyindoleacetic acid, programmed death-1, and cytotoxic T lymphocyte-associated protein 4 are explored, providing valuable information. Bioinformatics, with an emphasis on artificial intelligence, revolutionizes the analysis of biological data, offering more accurate diagnoses. Techniques like liquid biopsy are emphasized for early detection. Precision medicine guides therapeutic strategies based on the molecular characteristics of the tumor, as evidenced in the molecular subtypes of breast cancer. Classifications allow personalized treatments, highlighting the role of trastuzumab and endocrine therapies. Despite the benefits, challenges persist, including high costs, tumor heterogeneity, and ethical issues. Overcoming obstacles requires collaboration, ensuring that advances in molecular biology translate into accessible benefits for all.

A real-world survey on expensive drugs used as first-line chemotherapy in patients with HER2-negative unresectable advanced/recurrent gastric cancer in the stomach cancer study group of the Japan clinical oncology group.

Molecular-targeted drugs and immune checkpoint inhibitors have been developed for various malignant diseases, thereby improving clinical outcomes. However, these drugs are expensive, and few studies have assessed their actual use and costs in Japan. This study aimed to survey the use and costs of first-line chemotherapy for advanced/recurrent gastric cancer (AGC) in real-world settings. The survey included patients with human epidermal growth factor receptor type2 (HER2)-negative AGC who initiated first-line chemotherapy from January 2022 to December 2022 at the participating 92 institutions in the Japan Clinical Oncology Group. Data on the regimens were collected using Google Forms. A regimen that costs >500 000 Japanese yen (JPY) per month was defined as expensive. Data on chemotherapy regimens were collected from 2173 patients at all 92 institutions between March 2023 and May 2023. We analyzed 2113 patients who underwent the chemotherapy with recommended regimens and conditionally recommended regimens according to the Japanese Gastric Cancer Treatment Guidelines sixth edition. The expensive regimens were triplet chemotherapy with fluoropyrimidine (S-1 or capecitabine or 5-fluorouracil/levofolinate), oxaliplatin, and nivolumab. Their monthly costs ranged from 767 648 to 771 046 JPY. Nivolumab-containing regimens cost more than 20 times the price of conventional chemotherapy with fluoropyrimidine and oxaliplatin. These regimens were used in 1416 (67%) of 2113 patients: in 71% of patients aged ≤74years and in 59% of patients aged ≥75years. The regimens with >20-fold cost of conventional chemotherapy were used as first-line chemotherapy in two-thirds of patients and more than half even in the elderly population with HER2-negative AGC. This finding is important for future health economic studies on drug cost-efficacy.

Patient selection, ventricular tachycardia substrate delineation and data transfer for stereotactic arrhythmia radioablation. A Clinical Consensus Statement of the European Heart Rhythm Association (EHRA) of the ESC and the Heart Rhythm Society (HRS).

Stereotactic arrythmia radioablation (STAR) is a novel, non-invasive and promising treatment option for ventricular arrythmias (VA). It has been applied in highly selected patients mainly as bail-out procedure, when (multiple) catheter-ablations, together with anti-arrhythmic drugs, were unable to control the VAs. Despite the increasing clinical use there is still limited knowledge of the acute and long-term response of normal and diseased myocardium to STAR. Acute toxicity appeared to be reasonably low but potential late adverse effects may be underreported. Among published studies, the provided methodological information is often limited, and patient selection, target volume definition, methods for determination and transfer of target volume, and techniques for treatment planning and execution differ across studies, hampering pooling of data and comparison across studies. In addition, STAR requires close and new collaboration between clinical electrophysiologists and radiation oncologists, which is facilitated by shared knowledge in each collaborator's area of expertise and a common language. This clinical consensus statement provides uniform definition of cardiac target volumes. It aims to provide advice in patient selection for STAR including etiology specific aspects, and advice in optimal cardiac target volume identification based on available evidence. Safety concerns and the advice for acute and long-term monitoring including the importance of standardized reporting and follow-up are covered by this document. Areas of uncertainty are listed, which require high-quality, reliable pre-clinical and clinical evidence before expansion of STAR beyond clinical scenarios in which proven therapies are ineffective or unavailable.

Assessing olaparib efficacy in U.S. Veterans with metastatic prostate cancer utilizing a time-indifferent g-rate method ideal for real-world analyses

We aimed to assess real-world efficacy of the PARP inhibitor, olaparib, in US Veterans with metastatic prostate cancer (mPC) by leveraging the national data repository and evaluate a novel approach to assess treatment efficacy in tumors considered rare or harboring rare mutations. Included Veterans had 1) mPC with somatic or germline alterations/mutations in genes involved in homologous recombination repair (HRR), 2) received olaparib monotherapy as well as a novel hormonal therapy/androgen receptor pathway inhibitors (NHT/ARPI), and/or chemotherapy, and 3) estimable rates of tumor growth (g-rate) using PSA values obtained while receiving treatment. Previous work has shown an excellent inverse correlation of g-rate with survival. Using g-rate, we determined tumor doubling time (DT) and DT ratios (DT on olaparib/DT on prior medication). We postulated that a DT ratio≥ 1 was associated with benefit. We identified 139 Veterans, including 42 Black males with tumors harboring mutations/alterations in HRR genes who received olaparib: BRCA2 (50), ATM (32), BRCA1 (10), other mutations (47). 62/139 (45%) of all and 21/42 (50%) of Black Veterans had DT ratios ≥1, including 31, 10, 2, and 19 with BRCA2, ATM, BRCA1, and other mutations, respectively (p=0.006). Median survival with DT ratios ≥1 was superior, being 24.5 vs. 11.4 months for DT ratio <1 (p=0.01, HR 0.50, 95% CI 0.29-0.85). Benefit from olaparib, defined as DT ratio ≥1, was not observed for germline status, starting PSA value, number of prior therapies, or immediate prior therapy. Compared to matched cohorts, tumors in the olaparib cohort had shorter DTs with enzalutamide in first line (367 vs. 884 days; p=0.0043). Using equations indifferent to timing of assessments ideal for real-world efficacy analyses, we showed DT ratio ≥1 representing slower tumor growth on olaparib relative to the prior therapy correlates with improved survival. Olaparib efficacy in Veterans with mPC harboring mutations/alterations in HRR genes emulates clinical trial results. Black men had comparable results. Compared to matched cohorts, in first line, enzalutamide was less efficacious in tumors harboring mutations/alterations in HRR genes.

Tips for Accelerating BOIN Design.

During discussions at the Data Science Roundtable meeting in Japan, there were instances where the adoption of the BOIN design was declined, attributed to the extension of study duration and increased sample size in comparison to the 3 + 3 design. We introduce an accelerated BOIN design aimed at completing a clinical phase I trial at a pace comparable to the 3 + 3 design. Additionally, we introduce how we could have applied the BOIN design within our company, which predominantly utilized the 3 + 3 design for most of its clinical oncology dose escalation trials. The accelerated BOIN design is adaptable by using efficiently designated stopping criterion for the existing BOIN framework. Our approach is to terminate the dose escalation study if the number of evaluable patients treated at the current dose reaches 6 and the decision is to stay at the current dose for the next cohort of patients. In addition, for lower dosage levels, considering a cohort size smaller than 3 may be feasible when there are no safety concerns from non-clinical studies. We demonstrate the accelerated BOIN design using a case study and subsequently evaluate the performance of our proposed design through a simulation study. In the simulation study, the average difference in the percentage of correct MTD selection between the accelerated BOIN design and the standard BOIN design was - 2.43%, the average study duration and the average sample size of the accelerated BOIN design was reduced by 14.8 months and 9.22, respectively, compared with the standard BOIN design.

Status of incremental costs of first-line treatment recommended in Japanese clinical guidelines for metastatic breast cancer patients.

The increasing incidence and prevalence of breast cancer alongside diagnostic and treatment technology advances have produced a debate about the financial burden cancer places on the healthcare system and concerns about access. This study was conducted at 51 hospitals belonging to the Breast Cancer Study Group of the Japan Clinical Oncology Group using a web-based survey. The survey period conducted from July 2021 to June 2022. The study population included patients with metastatic breast cancer who received the related treatment as their first-line therapy. The proportion of patients who selected that regimen as their first-line treatment was tabulated. The total cost increase for each current standard therapy in comparison to conventional treatments was calculated. A total of 702 patients (pts) were surveyed. Of those enrolled, 342 (48.7%) received high-cost treatment [estimated monthly drug costs exceeding ~500 000 Japanese Yen (JPY)]. Of these, 16 pts (4.7%) were receiving very high-cost treatment, amounting to more than 1 000 000 JPY per month. Fifty three (15.5%) of the patients who received high-cost treatment were 75years of age or older. Of these, 1pt (0.3%) were receiving very high-cost treatment. Analyses of incremental costs by current drugs showed that abemaciclib was costly with total additional cost of 6 365 670 JPY per patient. The total additional cost of the regimen per patient that included palbociclib was the second highest at 4011248 JPY, followed by atezolizumab at 3209033 JPY. The findings indicate that evaluating the financial implications of high-cost treatments requires considering not only drug prices but also analysis of total cost increase.

Factors influencing fidelity to guideline implementation strategies for improving pain care at cancer centres: a qualitative sub-study of the Stop Cancer PAIN Trial

BackgroundThe Stop Cancer PAIN Trial was a phase III pragmatic stepped wedge cluster randomised controlled trial which compared effectiveness of screening and guidelines with or without implementation strategies for improving pain in adults with cancer attending six Australian outpatient comprehensive cancer centres (n = 688). A system for pain screening was introduced before observation of a ‘control’ phase. Implementation strategies introduced in the ‘intervention’ phase included: (1) audit of adherence to guideline recommendations, with feedback to clinical teams; (2) health professional education via an email-administered ‘spaced education’ module; and (3) a patient education booklet and self-management resource. Selection of strategies was informed by the Capability, Opportunity and Motivation Behaviour (COM-B) Model (Michie et al., 2011) and evidence for each strategy’s stand-alone effectiveness. A consultant physician at each centre supported the intervention as a ‘clinical champion’. However, fidelity to the intervention was limited, and the Trial did not demonstrate effectiveness. This paper reports a sub-study of the Trial which aimed to identify factors inhibiting or enabling fidelity to inform future guideline implementation initiatives.MethodsThe qualitative sub-study enabled in-depth exploration of factors from the perspectives of personnel at each centre. Clinical champions, clinicians and clinic receptionists were invited to participate in semi-structured interviews. Analysis used a framework method and a largely deductive approach based on the COM-B Model.ResultsTwenty-four people participated, including 15 physicians, 8 nurses and 1 clinic receptionist. Coding against the COM-B Model identified ‘capability’ to be the most influential component, with ‘opportunity’ and ‘motivation’ playing largely subsidiary roles. Findings suggest that fidelity could have been improved by: considering the readiness for change of each clinical setting; better articulating the intervention’s value proposition; defining clinician roles and responsibilities, addressing perceptions that pain care falls beyond oncology clinicians’ scopes of practice; integrating the intervention within existing systems and processes; promoting patient-clinician partnerships; investing in clinical champions among senior nursing and junior medical personnel, supported by medical leaders; and planning for slow incremental change rather than rapid uptake.ConclusionsFuture guideline implementation interventions may require a ‘meta-implementation’ approach based on complex systems theory to successfully integrate multiple strategies.Trial registrationRegistry: Australian New Zealand Clinical Trials Registry; number: ACTRN 12615000064505; data: https://www.anzctr.org.au/Trial/Registration/TrialReview.aspxid=367236&isReview=true.

Effect of reiki on people with advanced cancer: a randomized controlled trial

Introduction: Reiki is an Integrative and Complementary Health Practice (PICS), recognized and incorporated into the table of procedures of Brazil's Unified Health System (SUS). Objective: To evaluate the effects of applying Reiki in relieving the symptoms of people with advanced cancer who are hospitalized. Methodology: Randomized controlled study, approved by the Research Ethics Committee, to verify the effect of applying Reiki to people with advanced cancer, admitted to a large, highly complex university hospital located in the interior of the state of São Paulo, Brazil. Fourteen participants were selected from the clinical oncology ward and randomly divided into two groups - Reiki and control - with seven participants each. For data collection, an anamnesis was taken, blood pressure and heart rate were measured, saliva was collected to check cortisol levels; the Edmonton Symptom Assessment System (ESAS), Hospital Anxiety and Depression Scale (HAD-S) and Karnofsky Performance Status (KPS) were applied; Reiki was applied for 21 minutes to participants in the Reiki group and, 30 minutes after Reiki, the scales were reapplied and salivary cortisol was collected again. Results: The Mann-Whitney U-test showed a statistically significant difference for the sleep variable (p&lt;0.007) in the intervention group when compared to the control group. Conclusion: The results showed that Reiki improved the sleep of the participants in this randomized controlled trial and demonstrated that, despite the small caseload, the methodology used is valid for studying the impact of Reiki on the symptoms of people with advanced cancer.

The Impact of COVID-19 on Patients With Obsessive-Compulsive Disorder in Gulf Countries: A Narrative Review.

Gulf countries, like other parts of the world, were affected by the coronavirus disease 2019 (COVID-19) pandemic. Along with its biological effects, the pandemic has had serious psychological and social effects. The pandemic-associated general stress and the increased efforts of handwashing and general hygiene might trigger obsessive-compulsive disorder (OCD). The objective of this narrative review was to explore the influence of the COVID-19 pandemic on the prevalence, severity of symptoms, and accessibility of treatment for OCD in Gulf countries. A comprehensive literature search was conducted to review and collect research and/or reports on the prevalence, symptoms, diagnosis, and treatment adaptations and strategies of OCD during the ongoing COVID-19 pandemic in seven Arab Gulf countries. The search spanned from the onset of the crisis in 2020 to 2024. Peer-reviewed articles and reports were sourced from PubMed/Medline and Google Scholar, while abstracts presented at the American Society of Clinical Oncology (ASCO) and the European Society for Medical Oncology (ESMO) congresses were also included in the review. A total of four studies from Saudi Arabia, two from the United Arab Emirates, and two from Qatar were retrieved for analysis. These studies focused on investigating the impact of the pandemic on OCD. Studies from Kuwait, Oman, and Bahrain reported a negative impact of the pandemic on mental health, yet no specific data were provided. The studies highlighted an increased prevalence of OCD symptoms, both in terms of the incidence of new symptoms and the exacerbation of existing pre-pandemic manifestations. Furthermore, individuals with pre-existing psychological disorders or OCD were particularly susceptible to the negative impact of the pandemic. A review of local studies and reports from the Arab Gulf region reveals a striking paucity of research on the impact of the COVID-19 pandemic on OCD. The pandemic has been associated with an increase in the prevalence of OCD, the onset of new symptoms, and the worsening and exacerbation of existing pre-pandemic obsessions and compulsions.

Self-report of symptom cluster experiences in cancer patient-caregiver dyads.

Symptom clusters have important health implications in the context of cancer, but the symptom cluster experiences of cancer caregivers and patient-caregiver dyads are not well studied. To date, most studies report statistically derived symptom clusters among patients and fail to consider the caregivers' experience. This study aimed to assess and characterize self-reported symptom cluster experiences in cancer patient-caregiver dyads. We recruited 30 patient-caregiver dyads from the outpatient oncology clinics at a Comprehensive Cancer Center in the Midwestern U.S. Participants completed web-based surveys reporting their symptom clusters at weekly intervals over 8weeks of cancer treatment. Among 48 eligible dyads, 30 (63%) agreed to participate, 29 provided data, and ≥ 80% (24 patients, 26 caregivers) completed the study. Twenty-eight patients (97%) and twenty-two caregivers (76%) reported experiencing symptoms in clusters. There was substantial variability in the symptoms reported, perceived causality, and directional relationships among symptoms, however both patients' and caregivers' frequently described symptom clusters with psychoneurologic components (co-occurring pain, fatigue, sleep disturbance, anxiety, depression, lack of appetite and/or cognitive disturbance). Symptom clusters were perceived to have a moderate impact on patients' daily lives and a mild-to-moderate impact on caregivers' daily lives. Dyad members experienced and successfully self-reported symptom clusters, with psychoneurologic symptom clusters prevalent among both patients and their caregivers. Self-report of symptom cluster experiences provides unique insight relevant to clinical management. Findings provide foundational support for development and testing of dyad-based interventions to mitigate symptom clusters and their negative impact on daily life among cancer-patient caregiver dyads.

Revisiting Timing and Decision Modeling for Allogeneic Hematopoietic Stem-Cell Transplantation in Myelodysplastic Syndromes.

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.
