Chemotherapy-Induced Nausea and Vomiting: Pathogenesis, Recommendations, and New Trends

Conceptualisation and Measurement of Resilience of Adults With Cancer: An Umbrella Review

AIMS

To (1) clarify the key components of resilience of adults with cancer; (2) summarise and analyse the resilience measures used in this population; and (3) discuss future evaluation directions.

DESIGN

An umbrella review.

DATA SOURCES

MEDLINE, Embase, CINAHL, PsycINFO, Scopus, Cochrane library and Epistemonikos were searched in December 2023.

METHODS

The Joanna Briggs Institute (JBI) guidelines were followed for undertaking this umbrella review. Systematic and narrative reviews that defined resilience of adults with cancer and reported resilience measures, published in English, were included. The methodological quality was assessed using the JBI appraisal tool.

RESULTS

Fourteen eligible reviews were included. Four key resilience components from various resilience conceptualisations were identified. Twenty resilience measures were used among cancer patients, with the 25-item Connor-Davidson Resilience Scale providing a relatively comprehensive assessment of individual resilience. Recommended future research with cancer patients includes assessing these resilience components: (1) available individual resources-key psychological factors that enhance individual resilience; (2) access to social resources-close interpersonal relationships, family cohesion and social support; (3) adaptive coping ability-problem-solving skills, emotional management strategies and experiences in managing adversity; (4) ability to regain mental health and well-being-the capacity to recover a relatively stable psychological state and promote positive psychological functioning.

CONCLUSION

The findings provide evidence for refining future resilience measurement in the adult cancer population. Examining the four key components of resilience with this population across cultures is warranted.

IMPACT

Understanding the key components of resilience of cancer patients can help healthcare professionals identify individuals who may need further support and facilitate early intervention or referral to psychosocial support services. The 25-item Connor-Davidson Resilience Scale is recommended over other tools for use in the cancer population.

Management of Glucocorticoid-Induced Hyperglycemia in Cancer Patients: A Feasibility Study

Glucocorticoids are commonly used in the management of patients with hematological and solid malignancies. However, their use may be associated with impaired glycemic metabolism and increased treatment-related morbidity and mortality. This study aimed to examine the feasibility and acceptability of a nurse-led model of care (MOC) for screening and managing glucocorticoid-induced hyperglycemia (GIH) in non-diabetic patients requiring high-dose glucocorticoid (HDG) therapies, as well as patients' and health professionals' experiences with the MOC. This study was a single-site feasibility study. Patients with hematological or oncological malignancies who were >18 years of age, receiving a chemotherapy regimen including HDGs, had no prior diagnosis of diabetes or prediabetes, and were not at the end of life were considered eligible for this study. Participants were recruited from a district hospital's Cancer Centre in Australia. All consenting participants were screened for diabetes and were provided with a blood glucose meter to monitor their blood glucose levels (BGLs) four times a day on the days of glucocorticoid therapy (GT) plus one extra day following GT, for the first four cycles of their treatment, to screen for the presence of GIH. Feasibility and acceptability were assessed using rates of consent, study completion, and staff and patient surveys. Forty-eight percent (35/74) of patients approached consented to participate in the study and had screening tests for preexisting diabetes. None were diagnosed with diabetes. Six out of 35 patients withdrew, and 10/29 patients did not complete the recommended BGL monitoring. Thirteen percent (4/29) of patients developed GIH. The most common reasons for non-participation and study withdrawal were related to the self-monitoring of BGLs. While clinical stakeholders found the MOC feasible and acceptable, the results of this study suggest that alternative methods for encouraging self-monitoring of BGL and monitoring the presence of GIH during high-dose chemotherapy need to be explored to address issues associated with adherence and sustainability.

Targeting central pathway of Glucose-Dependent Insulinotropic Polypeptide, Glucagon and Glucagon-like Peptide-1 for metabolic regulation in obesity and type 2 diabetes

Obesity and type 2 diabetes are significant public health challenges that greatly impact global well-being. The development of effective therapeutic strategies has become more and more concentrated on the central nervous system and metabolic regulation. The primary pharmaceutical interventions for the treatment of obesity and uncontrolled hyperglycemia are now generally considered to be incretin-based anti-diabetic treatments, particularly glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide receptor agonists. This is a result of their substantial influence on the central nervous system and the consequent effects on energy balance and glucose regulation. It is increasingly crucial to understand the neural pathways of these pharmaceuticals. The purpose of this review is to compile and present the most recent central pathways regarding glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and glucagon receptors, with a particular emphasis on central metabolic regulation.

Facing stress and inflammation: From the cell to the planet

As identified in 1936 by Hans Selye, stress is shaping diseases through the induction of inflammation. But inflammation display some yin yang properties. On one hand inflammation is merging with the innate immune response aimed to fight infectious or sterile insults, on the other hand inflammation favors chronic physical or psychological disorders. Nature has equipped the cells, the organs, and the individuals with mediators and mechanisms that allow them to deal with stress, and even a good stress (eustress) has been associated with homeostasis. Likewise, societies and the planet are exposed to stressful settings, but wars and global warming suggest that the regulatory mechanisms are poorly efficient. In this review we list some inducers of the physiological stress, psychologic stress, societal stress, and planetary stress, and mention some of the great number of parameters which affect and modulate the response to stress and render it different from an individual to another, from the cellular level to the societal one. The cell, the organ, the individual, the society, and the planet share many stressors of which the consequences are extremely interconnected ending in the domino effect and the butterfly effect.

Assessment of antiemetic activity of dihydrocoumarin: In vivo and in silico approaches on receptor binding affinity and modulatory effects

Dihydrocoumarin (DCN) is a natural compound widely used in the flavor industry and has antioxidant and anti-inflammatory properties. However, its potential antiemetic effects on gastrointestinal disturbances remain untested. This study emphasizes assessing the antiemetic properties of the natural aromatic compound DCN using copper sulfate (CuSO4.5H2O)-induced emetic model on chicks, and an in silico approach was also adopted to estimate the possible underlying mechanisms. Two doses (25 and 50 mg/kg b.w.) of DCN and several referral drugs considered positive controls (PCs), including domperidone (6 mg/kg), hyoscine (21 mg/kg), aprepitant (16 mg/kg), diphenhydramine (10 mg/kg), and ondansetron (5 mg/kg), were orally administered to chicks. The vehicle was provided as the control group. Co-treatments of DCN with referral drugs were also provided to chicks to evaluate the modulatory action of the test compound. According to the results, DCN delayed the emetic onset and decreased the frequency of retches in a dose-dependent manner compared to the vehicle group. DCN (50 mg/kg) represented a notable delayed latency period (61.17 ± 4.12 s) and a diminished number of retchings (17.67 ± 1.82 times) compared to the control group. Further, in the co-treatments, DCN increased the latency period and reduced the number of retches, except for domperidone. In the in silico investigation, DCN showed notable binding affinity toward the D2 (-7 kcal/mol), H1 (-7.5 kcal/mol), and M5 (-7 kcal/mol) receptors in the same binding site as the referral ligand. Our research indicates that DCN has mild antiemetic properties by interacting with the D2, H1, and M5 receptors. Therefore, several pre-clinical and clinical studies are necessary to assess the effectiveness and safety profile of this food ingredient.

Ramosetron 3.0 μg/mL Combining with Dexamethasone (0.05, 0.1, 0.2 mg/mL) in Infusion Solutions: A Physicochemical Stability Study

Background

Dexamethasone in conjunction with type 3 serotonin receptor antagonists are being used to the prevention and treatment of chemotherapy-induced nausea and vomiting and postoperative nausea and vomiting in clinic. The present study aimed to investigates the stability of ramosetron with dexamethasone in infusions, with the goal of enhancing the safety and clinical applicability of their combined use.

Methods

Ramosetron hydrochloride (3.0 μg/mL) combining with dexamethasone (0.05, 0.1, 0.2 mg/mL) were prepared with 0.9% sodium chloride injection and then packaged in polyolefin bags or glass bottles. The stability were investigated kept in the dark at refrigeration for 14 days and at room temperature for 48 h.

Results

The concentration of both drugs maintained at least 97% in the various solutions for both storage conditions with light protection. In the light exposure conditions, as the extension of storage time, the concentration of both drugs had declined. All antiemetic mixture solutions remained clear and no changes in color, turbidity, precipitation, and the pH remained stable. The insoluble particles were in line with Chinese Pharmacopoeia.

Conclusion

Our findings suggest that combinations of ramosetron hydrochloride with dexamethasone sodium phosphate in 0.9% sodium chloride injection remain stable for 14 days at 4°C and 48 h at 25°C when protected from light.

The Gut Microbial Lipid Metabolite 14(15)-EpETE Inhibits Substance P Release by Targeting GCG/PKA Signaling to Relieve Cisplatin-Induced Nausea and Vomiting in Rats

Chemotherapy-induced nausea and vomiting (CINV) is a debilitating side effect related to activation of substance P (SP). SP activation can result from dysregulation of the gut-brain axis, and also from activation of protein kinase A signaling (PKA) signaling. In this study, we connected these factors in an attempt to unveil the mechanisms underlying CINV and develop new therapeutic strategies. Female rats were injected with cisplatin (Cis) to induce pica. Fecal samples were collected before/after injection, and subjected to lipid metabolomics analysis. In another portion of pica rats, the PKA inhibitor KT5720 was applied to investigate the involvement of PKA signaling in CINV, while fecal microbiota transplantation (FMT) was implemented to verify the therapeutic effect of the lipid metabolite 14(15)-EpETE. Pica symptoms were recorded, followed by ileal histological examination. The targeting relationship between 14(15)-EpETE and glucagon was determined by bioinformatics. SP and glucagon/PKA signaling in rat ileum, serum, and/or brain substantia nigra were detected by immunohistochemistry, enzyme-linked immunosorbent assay, and/or western blot. The results showed a significantly lower level of 14(15)-EpETE in rat feces after Cis injection. KT5720 treatment alleviated Cis-induced pica symptoms, ileal injury, SP content increase in the ileum, serum, and brain substantia nigra, and ileal PKA activation in rats. The ileal level of glucagon was elevated by Cis in rats. FMT exerted an effect similar to that of KT5720 treatment, relieving the Cis-induced changes, including ileal glucagon/PKA activation in rats. Our findings demonstrate that FMT restores 14(15)-EpETE production, which inhibits SP release by targeting GCG/PKA signaling, ultimately mitigating CINV.

Effectiveness of e-health interventions for chemotherapy-induced nausea and vomiting: a systematic review and meta-analysis

INTRODUCTION

The goal of this systematic review was to examine the effectiveness of e-health interventions for chemotherapy-induced nausea and vomiting (CINV).

METHODS

A literature search was conducted across the databases of PubMed, Web of Science, Embase, CINAHL, and Cochrane Library from database establishment to 3 March 2024. We included randomized controlled trials in English where the intervention group was via e-health. Two reviewers independently carried out the screening, data extraction, and quality appraisal of the studies. Using Stata 17.0, meta-analyses were conducted to synthesize the effects of outcomes of interest.

RESULTS

A total of 6663 studies were retrieved, with only 8 RCTs meeting criteria, involving 620 patients. Meta-analysis revealed that e-health interventions significantly reduce CINV severity (MD =  - 7.687; 95% CI - 11.903, - 3.326; p < 0.001). However, results regarding CINV incidence reduction and quality of life improvement are inconclusive due to variations in intervention content, modality, and frequency among studies.

CONCLUSIONS

e-health interventions may reduce the severity and incidence of CINV, while enhancing quality of life. However, the results should be interpreted cautiously. Higher quality studies are needed in the future to further validate the effectiveness of e-health interventions for CINV.

Research trends on chemotherapy induced nausea and vomiting: a bibliometric analysis

Background

CINV is a frequent adverse response to cancer treatment. There is still much to learn about the pathophysiology and initiating event of CINV, which necessitates continued research despite decades of effort. Identifying the current foci of the complex disease and assessing the scientific impact of pertinent study are made more difficult by the abundance of publications on CINV. Therefore, our goals in this article are to evaluate developments in this field, examine patterns in research domains, and gauge the expansion of CINV research production globally.

Methods

Articles about CINV published between 2012 and 2022 were found by searching the Web of Science Core Collection of Clarivate Analytics. The number of publications over time was visualized using Microsoft Office Excel 2019. CiteSpace and VOSviewer were utilized to create knowledge maps that analyzed collaborations between nations, organizations, and writers. They also presented the history of CINV research and highlighted its current areas of focus.

Results

In this study, 846 papers in all were assessed. Most publications (237, 28.01%) came from the United States. University of Toronto was the most productive institution (34, 4.01%). With 25 articles published, or 2.96% of the total, Aapro Matti published the most. The most frequently published journal was found to be Supportive Care (158, 18.68%). "Palonosetron," "Moderately emetogenic chemotherapy," "5-HT3 receptor antagonist," and "Neurokinin 1 receptor antagonists" were considered the hot topics. It can be seen that the research focus is on the drug treatment of chemotherapy-induced nausea and vomiting.

Conclusion

Through bibliometric analysis, we were able to gain profound insights into CINV research for the first time. Researchers looking to uncover research frontiers and comprehend important information in this discipline may find the study's findings useful.

Dexamethasone-Sparing Antiemetic Prophylaxis for Chemotherapy-Induced Nausea and Vomiting in Highly and Moderately Emetogenic Chemotherapy: The SHEILD Study

BACKGROUND

Chemotherapy-induced nausea and vomiting (CINV) significantly impacts patient's quality of life and treatment adherence. This study investigated the efficacy of Generic Netupitant and Palonosetron tablets (Nykron) with dexamethasone single dose for CINV prophylaxis in patients receiving highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC). Additionally, this approach aligns with the principles of the SHIELD study (Sparing High Efficacy Intervention for Low Dose Dexamethasone), which focuses on maximizing antiemetic effectiveness while minimizing dexamethasone use.

METHODOLOGY

This multicenter retrospective study evaluates data from patients who received HEC/MEC and were administered a fixed-dose combination of Generic NEPA (Netupitant 300 mg and Palonosetron 0.5 mg tablets, Nykron combi-pack) along with a single dose of dexamethasone (12 mg/8 mg) before chemotherapy. The data were collected from September 2022 till September 2023. Outcomes measured included complete response (no vomiting and no need for rescue medications), complete protection (no significant nausea (<2.5 cm on VAS), no vomiting, and no use of rescue medication), and complete control (no emetic episodes, no rescue therapy, and no nausea [0 cm on VAS]) during the acute phase (0-24 hours) and delayed phase (24-120 hours) post-chemotherapy.

RESULTS

The data of 372 patients was evaluated in which breast cancer was the most common cancer with 223 (59.95%) patients for which doxorubicin and cyclophosphamide (192, 51.61%) was the most administered chemotherapy combination. The second most common cancer was gastrointestinal (GI) cancer with stomach cancer in 47 (12.6%), colorectal cancer in 4 (1%), and pancreatic cancer in 2 (0.54%). A total of 360 (96.8%) patients received an HEC regimen across the cycle, while only 5 (1.3%) received an MEC regimen. The regimen demonstrated exceptional efficacy with a 96.9% overall response rate across all cycles. Complete control rates for acute CINV were 92% and 90% for delayed CINV across chemotherapy cycles. Complete response rates remained consistently high (94%-98%) across all cycles and overall phases. Only 3% of patients experienced anticipatory CINV.

CONCLUSIONS

This dexamethasone-sparing Generic NEPA regimen showed remarkable efficacy in CINV management for HEC/MEC regimen-receiving patients, maintaining high response rates in both acute and delayed across all cycles. These findings indicate a potential paradigm shift in CINV prophylaxis, necessitating further investigation through prospective, randomized controlled trials to validate long-term safety and efficacy.

Chinese guidelines for integrated diagnosis and treatment of intestinal microecology technologies in tumor application (2024 Edition)

ABSTRACT

Intestinal microecology (IM) is the largest and most important microecological system of the human body. Furthermore, it is the key factor for activating and maintaining the physiological functions of the intestine. Numerous studies have investigated the effects of the gut microbiota on the different tissues and organs of the human body as well as their association with various diseases, and the findings are gradually being translated into clinical practice. The gut microbiota affects the occurrence, progression, treatment response, and toxic side effects of tumors. The deepening of research related to IM and tumors has opened a new chapter in IM research driven by methods and technologies such as second-generation sequencing and bioinformatics. The IM maintains the function of the host immune system and plays a pivotal role in tumor-control drug therapy. Increasing evidence has proven that the efficacy of tumor-control drugs largely depends on the IM balance, and strategies based on the IM technology show promising application prospects in the diagnosis and treatment of tumor. The Tumor and Microecology Professional Committee of the Chinese Anti-cancer Association gathered relevant experts to discuss and propose the "Chinese guidelines for integrated diagnosis and treatment of IM technologies in tumor application (2024 Edition)," which was established based on the research progress of the application of the IM technology in tumor to provide a basis for the standardization of the diagnosis and treatment of the IM technology in the tumor.

Safety assessment of neurokinin-1 receptor antagonist: real-world adverse event analysis from the FAERS database

Background

Aprepitant, fosaprepitant, and netupitant are three common neurokinin-1 receptor antagonists (NK-1RAs) used to prevent chemotherapy-induced nausea and vomiting, following highly or moderately emetogenic chemotherapy. Understanding their different adverse event (AE) profiles may help clinicians make appropriate treatment decisions.

Methods

All data collected from the FDA Adverse Event Reporting System (FAERS) database from the first quarter of 2004 to the fourth quarter of 2023 underwent disproportionality analysis to detect, evaluate, and compare AE signals of the three NK-1RAs.

Results

A total of 3,904, 1,123, and 243 AE reports related to aprepitant, fosaprepitant, and netupitant, respectively, were extracted from the FAERS database. Of these, more than 50% of respondents were female, and most of them were aged 45-65 years. General disorders and administration-site conditions, and gastrointestinal disorders were the most frequent signals in the system organ class of the three NK-1RA drugs. In addition, aprepitant was strongly associated with joint deposit (ROR = 26.27) and fosaprepitant was closely related to seizure-like phenomena (ROR = 26.90); two preferred terms (PTs) were not mentioned in the manual. Statistically, netupitant was likely to induce death (N = 63, ROR = 8.78, 95% CI: 6.75-11.42). Additionally, neutropenic colitis, colitis, and stomatitis were unique to netupitant. Furthermore, the AE profiles of the three NK-1RA drugs were different by gender.

Conclusion

The AE profiles for aprepitant, fosaprepitant, and netupitant were different. In addition to paying attention to common AEs, clinicians need to pay attention to new emerging AEs, such as joint deposit, seizure-like phenomena, neutropenic colitis, colitis, and stomatitis, regarding the three NK-1RA drugs. Furthermore, the AE compositions of the three NK-1RA drugs were different in different genders, and clinicians should take these factors into account when selecting NK-1RAs for CINV treatment.

Relationship between nausea and vomiting and physical activity in patients with lung cancer undergoing first chemotherapy

Objective

Nausea and vomiting are the distressing and debilitating side effects of chemotherapy. This study explores the relationship between the degree of nausea and vomiting and physical activity in patients with lung cancer during the first chemotherapy cycle.

Design

A total of 107 patients with lung cancer who received platinum drugs during chemotherapy in a hospital in Shanghai, China, in 2023 were involved in this study. Data were collected with medical record system and self-reported questionnaires.Questionnaires included the International Physical Activity Questionnaire (IPAQ) and Index of Nausea, Vomiting, and Retching (INVR). IPAQ was used before chemotherapy; INVR was used on the second and sixth day of chemotherapy, followed by the analysis of the correlation between physical activity status and degree of nausea and vomiting during chemotherapy. The influencing factors of nausea and vomiting during chemotherapy in patients with lung cancer were analyzed using logistic regression analysis.

Results

More than half of the patients experienced nausea, vomiting or retching related symptoms after chemotherapy, and the proportion of moderate to high physical activity was 50.5%. Univariate analysis showed that the degree of nausea and vomiting was influenced by factors such as age, gender, and history of drinking (P < 0.05). The degree of nausea and vomiting was negatively correlated with physical activity (P < 0.05). The multivariate linear analysis showed that gender, history of drinking, and moderate and high physical activity are contributing factors to nausea and vomiting during chemotherapy (P < 0.05).

Conclusion

Moderate and high physical activity before chemotherapy is a protective factor for nausea and vomiting in patients with lung cancer. Physical activity can not only improve the degree of nausea and vomiting in patients with lung cancer but also reduce the incidence in these patients during the first chemotherapy cycle.

Yoga as a Complementary Therapy for Cancer Patients: From Clinical Observations to Biochemical Mechanisms

BACKGROUND

Integrative oncology combines conventional and complementary, or integrative, therapies for a holistic treatment of cancer patients. Yoga is increasingly used as a complementary therapy for cancer patients, but there is no direct evidence for its effect on cancer pathophysiology like tumor response, or patient outcome like overall survival.

SUMMARY

In this narrative review, we present in detail published studies from randomized clinical trials on complementary yoga therapy for cancer patients, including details about the biochemical mechanisms involved. Medicinal hatha yoga with breathing, postures, meditation, and relaxation enhances the quality of life of cancer patients by providing both psychological and physiological health benefits, highlighting the interconnectedness of mind and body. Yoga therapy reduces stress levels improving heart rate variability, leading to changes in hormonal regulation (e.g., cortisol), reduced oxidative stress, and improved immune function with reduced inflammation. Still, the biochemical effects of yoga on the cancer disease itself are unrevealed.

KEY MESSAGES

More clinical and basic research is needed for further establishment of yoga as complementary therapy in oncology.

Low dose of dexamethasone combined with netupitant and palonosetron in preventing nausea and vomiting in breast cancer patients induced by anthracycline drugs

BACKGROUND

To study the effects of various courses of dexamethasone (DEX) combined with 5-HT3 receptor antagonists (RA) and NK-1 RA in suppressing high-grade nausea and vomiting (CINV) caused by anthracycline and cyclophosphamide chemotherapy regimens (AC or EC) in breast cancer (BC) patients.

PATIENTS AND METHODS

A prospective study was performed with 252 BC patients who received AC between January, 2019 and June, 2022 in our hospital. Patients were randomly separated into control Group (N = 130) who received DEX 12 mg on day 1 and 8 mg per dose on day 2-4 and observation group (N = 122) treated with DEX 5 mg per dose on days 1-4. The response was monitored. Primary study endpoint was complete resolution (CR) of patients nausea or vomiting; secondary study endpoints included acute CR and delayed CR; and complete control (CC), acute CC, delayed CC, and safety.

RESULTS

All patients underwent six rounds of chemotherapy, and no difference was found in the clinical data. CR of acute/delayed phase was (94.3%/88.5%, P > 0.05), (89.3%/90.8%, P > 0.05); total CR was (80.3%/81.5%, P > 0.05); CC was (56.6%/59.2%, P > 0.05), (64.8%/67.7%, P > 0.05); total CR was (48.4%/53.1%, P > 0.05).

CONCLUSIONS

The preventive antiemetic effects of NEPA, a fixed-dose combination of netupitant and palonosetron combined with DEX 5 mg per dose on days 1-4, can be similar to DEX 12 mg on day 1 and 8 mg per dose on days 2-4, low-dose hormone with better safety, which is beneficial.

Effect of peppermint inhalation versus Swedish massage on chemotherapy induced-nausea and vomiting in children with leukemia: Multi-arm randomised trial design

BACKGROUND

Chemotherapy is the foremost treatment for children with leukemia, while causing different serious side-effects. Chemotherapy-induced nausea and vomiting are the most common deliberating side effects and critical concerns of pediatric oncology nurses among those children.

AIM

To investigate the effect of peppermint inhalation versus Swedish massage on chemotherapy-induced nausea and vomiting in children with leukemia.

DESIGN

A multi-arm randomised trial design with three parallel groups.

SETTING

This study was conducted at outpatient and inpatient Hematology/leukemia Units at Alexandria University Children's Hospital at Smouha.

METHODS

Seventy-five children with leukemia received the first chemotherapy session. They were randomly allocated into three equal groups, 25 children in each group (control, peppermint inhalation, and Swedish massage groups). Every child is assessed for nausea and vomiting before chemotherapy administration and after for three days for consecutive three sessions of treatment.

RESULTS

Study findings revealed that children in peppermint inhalation and Swedish massage groups showed significant reduction in mean total score of chemotherapy-induced nausea and vomiting among peppermint inhalation and Swedish groups (15.120 ± 4.585 and 14.680 ± 3.158, respectively) was observed on third chemotherapy session than in control group (45.680 ± 5.793) (p < 0.001).

CONCLUSION

It can be concluded that Swedish massage and peppermint inhalation therapies may have significant antiemetic effects as alleviating the chemotherapy induced nausea and vomiting for children with leukemia.

PRACTICE IMPLICATIONS

This study directs the pediatric oncology nurses to incorporate peppermint inhalation and Swedish massage therapies besides antiemetic drugs in pediatric oncology unit protocols for management of chemotherapy induced nausea and vomiting.

In their voices: Kenyan women's experiences with cancer treatment-related side effects

Objective

This article reports on a secondary analysis of a qualitative study conducted in Nairobi, Kenya that reported several initial themes. In this article, the authors explore the theme of treatment-related side effect management by women receiving treatment for breast or cervical cancer.

Methods

Women were interviewed at three points during their active treatment trajectory. Participants were purposefully selected and saturation was reached when interviews did not yield any new themes. The interviews were transcribed and analyzed for internal consistency, frequency, extensiveness, intensity and specificity. The Nvivo pro 12 software was used in organizing and managing the data to facilitate analysis.

Results

Eighteen women were interviewed. Major side effects reported by participants included fatigue, alopecia, skin and nail changes as well as nausea and vomiting. Women who received information prior to treatment were more comfortable managing side effects. Participants described the impact of side effects on their daily life, body image, and many sought comfort through faith. Some women provided suggestions on strategies for patient education.

Conclusions

This study attempted to capture the cancer treatment-related experiences of Kenyan women in their own voices and present strategies for future intervention and research. The care of individuals receiving treatment can be enhanced through the advancement of health human resources, the development of nationally accessible patient education materials and research on regionally relevant strategies to manage cancer treatment-related side effects.

Effect of Music Therapy on Chemotherapy Anticipatory Symptoms in Adolescents: A Mixed Methods Study

INTRODUCTION

This study explores the feasibility and effects of music therapy on anticipatory nausea and vomiting, stress, pain and quality of life in adolescents undergoing chemotherapy.

METHODS

This is a single group, quasi-experimental study using pre/post-test design. Participants received four individual sessions of music therapy (MT), led by a certified music therapist. State-Trait-Anxiety Inventory Y-1, and a 0-4 Likert scale for pain, nausea and vomiting were recorded. Heart rate variability (LF/HF) was collected during sessions. PedsQL was collected before and at the end of the trial. Semi-structured interviews were conducted with participants.

RESULTS

A significant reduction in anxiety, nausea and vomiting, both pre-post single sessions and between different sessions, was observed. A significant increase in LF/HF and PedsQL scores was observed. Relevant themes also emerged from interviews.

CONCLUSION

Results support the feasibility of introducing music therapy with adolescents undergoing chemotherapy. Perceived stress and psychological/physical wellbeing were improved in participants.

Stress relief of chemo illness

New studies (Tang et al. 2024. J. Exp. Med.https://doi.org/10.1084/jem.20231395) describe a liver stress pathway that is activated by certain chemotherapeutic drugs, which in turn induces a peptide hormone which partially mediates the lower food intake and body weight loss during chemotherapy treatment.

The efficacy and safety of Xiao-Ban-Xia-Tang in the treatment of chemotherapy-induced nausea and vomiting: A systematic review and meta-analysis

Background

Chemotherapy-induced nausea and vomiting (CINV) is one of the most frequent and critical side effects due to chemotherapeutics. In China, Xiao-Ban-Xia-Tang (XBXT) has already been applied extensively to prevent and treat CINV. However, there is limited testimony on the effectiveness and safety of this purpose, and there was no correlative systematic review. The aim of this review was to systematically evaluate the effectiveness and safety of XBXT in preventing and treating CINV.

Methods

The systematic search was conducted in eight databases to acquire randomized controlled trials (RCTs) that appraised the effect of XBXT in treating CINV. The vomiting and nausea relief efficiency, eating efficiency, quality of life, and adverse reactions were explored for efficacy assessment. Bias risk was rated by manipulating the Cochrane risk of bias tool 2.0 (RoB 2). The retrieved investigations were analyzed by utilizing ReviewManager 5.4 and Stata 17.0. The quality of evidence was evaluated adopting the GRADE tool.

Results

A total of 16 clinical RCTs of XBXT in the treatment of CINV were incorporated into the investigation, with a total of 1246 participants. The meta-analysis showed that compared with conventional antiemetic drugs, XBXT and antiemetics improved the vomiting relief efficiency (RR 1.35, 95% confidence interval: 1.25-1.46, p < 0.00001), nausea relief efficiency (N = 367, RR 1.23, 95% CI: 1.09-1.38, p < 0.00001), and quality of life (RR = 1.37, 95% CI: 1.14-1.65, p = 0.0009) and reduced the adverse events (N = 370, RR 0.53, 95% CI: 0.29-0.96, p = 0.04). XBXT and DARAs raised eating efficiency compared with DARAs (N = 208, RR 1.30, 95% CI: 1.07-1.57, p = 0.007). The data existed as statistically significant, and the publication bias was identified as relatively low from the funnel plot and trim and fill analysis. In addition, sensitivity analysis demonstrated robust outcomes. The quality of evidence for each outcome ranged from moderate to high.

Conclusion

There is some encouraging evidence that XBXT and antiemetics had better therapeutic effects and safety in treating CINV than antiemetic drugs alone. The quality assessment and low publication bias indicated that the overall criterion was scientific. Better research is required to verify the evidence designed with large-scale RCTs and rigorous methods.

Outcome of antiemetic prophylaxis among pediatric cancer patients receiving moderate to highly emetogenic chemotherapy at pediatric hemato-oncology ward of Tikur Anbessa specialized hospital: A prospective observational study

INTRODUCTION

Chemotherapy-induced nausea and vomiting (CINV) is a major issue for chemotherapy pediatric patients, especially in developing countries due to limited access to essential antiemetics. This study aimed to assess antiemetic prophylaxis outcomes in pediatric cancer patients at Tikur Anbessa Specialized Hospital in Addis Ababa, Ethiopia.

METHODS

A longitudinal prospective observational study design was conducted among 201 pediatric cancer patients followed up to 120 h post-chemotherapy.

RESULTS

The majority of patients (75.1%) received combination prophylactic antiemetics in the acute phase. Complete response (CR) was the highest in the acute phase (71.1%). Emesis episodes occurred most frequently on the first day of treatment (28.4%) and gradually decreased over time. History of motion sickness, platinum-based chemotherapy, and prior chemotherapy-induced vomiting (CIV) were associated with emesis during the acute phase whereas multiple-day chemotherapy, prior CIV, receipt of antiemetics, and a history of motion sickness in the delayed phase. However, the odds of CIV were reduced with steroid presence in the chemotherapy regimen.

CONCLUSIONS

A considerable number of participants could not achieve a CR. It is important for clinicians to be cognizant of risk factors that influence the outcome of antiemetic prophylaxis to achieve better control of CINV among pediatric cancer patients.

Prevalence of anticipatory nausea and vomiting in breast cancer patients undergoing highly emetogenic chemotherapy

OBJECTIVE

Anticipatory nausea and vomiting are unpleasant symptoms observed before undergoing chemotherapy sessions. Less is known about the occurrence of symptoms since the advent of the new neurokinin-1 antagonist.

METHODS

This prospective cohort study was performed at a single Brazilian Institution. This study included breast cancer patients who received doxorubicin and cyclophosphamide chemotherapy and an appropriate antiemetic regimen (dexamethasone 10 mg, palonosetron 0.56 mg, and netupitant 300 mg in the D1 followed by dexamethasone 10 mg 12/12 h in D2 and D4). Patients used a diary to record nausea, vomiting, and use of rescue medication in the first two cycles of treatment. The prevalence of anticipatory nausea and vomiting was assessed before chemotherapy on day 1 of C2.

RESULTS

From August 4, 2020, to August 12, 2021, 60 patients were screened, and 52 patients were enrolled. The mean age was 50.8 (28-69) years, most had stage III (53.8%), and most received chemotherapy with curative intent (94%). During the first cycle, the frequency of overall nausea and vomiting was 67.31%, and that of severe nausea and vomiting (defined as grade>4 on a 10-point visual scale or use of rescue medication) was 55.77%. Ten patients had anticipatory nausea and vomiting (19.23%). The occurrence of nausea and vomiting during C1 was the only statistically significant predictor of anticipatory nausea and vomiting (OR=16, 95%CI 2.4-670.9, p=0.0003).

CONCLUSION

The prevalence of anticipatory nausea is still high in the era of neurokinin-1 antagonists, and failure of antiemetic control in C1 remains the main risk factor. All efforts should be made to control chemotherapy-induced nausea or nausea and vomiting on C1 to avoid anticipatory nausea.

Mechanisms driving fasting-induced protection from genotoxic injury in the small intestine

Genotoxic agents such as doxorubicin (DXR) can cause damage to the intestines that can be ameliorated by fasting. How fasting is protective and the optimal timing of fasting and refeeding remain unclear. Here, our analysis of fasting/refeeding-induced global intestinal transcriptional changes revealed metabolic shifts and implicated the cellular energetic hub mechanistic target of rapamycin complex 1 (mTORC1) in protecting from DXR-induced DNA damage. Our analysis of specific transcripts and proteins in intestinal tissue and tissue extracts showed that fasting followed by refeeding at the time of DXR administration reduced damage and caused a spike in mTORC1 activity. However, continued fasting after DXR prevented the mTORC1 spike and damage reduction. Surprisingly, the mTORC1 inhibitor, rapamycin, did not block fasting/refeeding-induced reduction in DNA damage, suggesting that increased mTORC1 is dispensable for protection against the initial DNA damage response. In Ddit4-/- mice [DDIT4 (DNA-damage-inducible transcript 4) functions to regulate mTORC1 activity], fasting reduced DNA damage and increased intestinal crypt viability vs. ad libitum-fed Ddit4-/- mice. Fasted/refed Ddit4-/- mice maintained body weight, with increased crypt proliferation by 5 days post-DXR, whereas ad libitum-fed Ddit4-/- mice continued to lose weight and displayed limited crypt proliferation. Genes encoding epithelial stem cell and DNA repair proteins were elevated in DXR-injured, fasted vs. ad libitum Ddit4-/- intestines. Thus, fasting strongly reduced intestinal damage when normal dynamic regulation of mTORC1 was lost. Overall, the results confirm that fasting protects the intestines against DXR and suggests that fasting works by pleiotropic - including both mTORC1-dependent and independent - mechanisms across the temporally dynamic injury response.NEW & NOTEWORTHY New findings are 1) DNA damage reduction following a 24-h fast depends on the timing of postfast refeeding in relation to chemotherapy initiation; 2) fasting/refeeding-induced upregulation of mTORC1 activity is not required for early (6 h) protection against DXR-induced DNA damage; and 3) fasting increases expression of intestinal stem cell and DNA damage repair genes, even when mTORC1 is dysregulated, highlighting fasting's crucial role in regulating mTORC1-dependent and independent mechanisms in the dynamic recovery process.

Efficacy and Safety of Ginger on Chemotherapy-Induced Nausea and Vomiting: A Systematic Review and Meta-analysis of Randomized Controlled Trials

BACKGROUND

Chemotherapy-induced nausea and vomiting (CINV) is a prevalent and distressing side effect. Historically, ginger has been explored as a potential remedy for various ailments, including its potential efficacy against CINV.

OBJECTIVE

The aim of this study was to determine whether taking ginger supplements can relieve CINV.

METHOD

A comprehensive search was conducted across PubMed, EMBASE, Cochrane Library, and the Wanfang database. Randomized controlled trials meeting our inclusion criteria were analyzed. The primary outcomes were the incidence and severity of CINV. The protocol was registered on PROSPERO, and the number is CRD4202232104.

RESULT

Of the 35 randomized controlled trials analyzed, 22 trials employed ginger capsules as the primary intervention, whereas 13 studies evaluated the prophylactic effects of ginger-partitioned moxibustion. The outcomes indicated that combining ginger capsules with standard antiemetic agents can significantly reduce the incidence of grade 3 acute nausea (Risk Ratio [RR], 0.19; P < .001) and the incidence of high-grade overall vomiting (RR, 0.47; P = .01). Moreover, ginger-partitioned moxibustion can significantly alleviate the incidence of both mild (RR, 0.56; P = .001) and severe (RR, 0.39; P < .00001) vomiting. Only 2.8% of patients experienced dizziness after ginger-partitioned moxibustion.

CONCLUSIONS

Our findings indicate that ginger capsules, when used alongside antiemetic drugs, enhance the management of severe CINV, particularly in highly emetogenic chemotherapy regimens.

IMPLICATIONS FOR PRACTICE

Based on our findings, we recommend initiating ginger supplements before chemotherapy, in conjunction with standard antiemetics, to reduce the severity of CINV. The promising results warrant more rigorous clinical trials to firmly establish the role of ginger in CINV management.

Prevention and management of acute toxicities from conditioning regimens during hematopoietic stem cell transplantation

Hematopoietic stem cell transplantation (HSCT) remains the only curative option for several hematological malignancies. Its use has continued to grow, with an estimated 23,500 transplants performed annually in the United States alone. The acute toxicities that occur from conditioning chemotherapy can impact the peri-transplant period and have substantial implications on patients' tolerability and outcomes, irrespective of the treatment of their disease. Chemotherapy-induced nausea vomiting (CINV), mucositis, transplant-associated thrombotic microangiopathy (TA-TMA), and sinusoidal obstruction syndrome, also known as a veno-occlusive disease (SOS/VOD) can all have significant implications for patients. These acute complications begin with the start of conditioning chemotherapy and add to potential toxicity for patients throughout the early post-transplant period, from Day +30 for CINV, mucositis, and SOS, and which can continue through at least Day +100 with the onset of TA-TMA. These toxicities must be prevented and managed appropriately. This review will summarize the literature surrounding them and guide their management.

The antiemetic actions of GIP receptor agonism

Nausea and vomiting are primitive aspects of mammalian physiology and behavior that ensure survival. Unfortunately, both are ubiquitously present side effects of drug treatments for many chronic diseases with negative consequences on pharmacotherapy tolerance, quality of life, and prognosis. One of the most critical clinical examples is the profound emesis and nausea that occur in patients undergoing chemotherapy, which continue to be among the most distressing side effects, even with the use of modern antiemetic medications. Similarly, antiobesity/diabetes medications that target the glucagon-like peptide-1 system, despite their remarkable metabolic success, also cause nausea and vomiting in a significant number of patients. These side effects hinder the ability to administer higher dosages for optimal glycemic and weight management and represent the major reasons for treatment discontinuation. Our inability to effectively control these side effects highlights the need to anatomically, molecularly, and functionally characterize novel neural substrates that drive and inhibit nausea and emesis. Here, we discuss clinical and preclinical evidence that highlights the glucose-dependent insulinotropic peptide receptor system as a novel therapeutic central target for the management of nausea and emesis.

Antiemetic activity of abietic acid possibly through the 5HT3 and muscarinic receptors interaction pathways

The present study was designed to evaluate the antiemetic activity of abietic acid (AA) using in vivo and in silico studies. To assess the effect, doses of 50 mg/kg b.w. copper sulfate (CuSO4⋅5H2O) were given orally to 2-day-old chicks. The test compound (AA) was given orally at two doses of 20 and 40 mg/kg b.w. On the other hand, aprepitant (16 mg/kg), domperidone (6 mg/kg), diphenhydramine (10 mg/kg), hyoscine (21 mg/kg), and ondansetron (5 mg/kg) were administered orally as positive controls (PCs). The vehicle was used as a control group. Combination therapies with the referral drugs were also given to three separate groups of animals to see the synergistic and antagonizing activity of the test compound. Molecular docking and visualization of ligand-receptor interaction were performed using different computational tools against various emesis-inducing receptors (D2, D3, 5HT3, H1, and M1-M5). Furthermore, the pharmacokinetics and toxicity properties of the selected ligands were predicted by using the SwissADME and Protox-II online servers. Findings indicated that AA dose-dependently enhances the latency of emetic retching and reduces the number of retching compared to the vehicle group. Among the different treatments, animals treated with AA (40 mg/kg) exhibited the highest latency (98 ± 2.44 s) and reduced the number of retching (11.66 ± 2.52 times) compared to the control groups. Additionally, the molecular docking study indicated that AA exhibits the highest binding affinity (- 10.2 kcal/mol) toward the M4 receptors and an elevated binding affinity toward the receptors 5HT3 (- 8.1 kcal/mol), M1 (- 7.7 kcal/mol), M2 (- 8.7 kcal/mol), and H1 (- 8.5 kcal/mol) than the referral ligands. Taken together, our study suggests that AA has potent antiemetic effects by interacting with the 5TH3 and muscarinic receptor interaction pathways. However, additional extensive pre-clinical and clinical studies are required to evaluate the efficacy and toxicity of AA.

Effects of Physical Cues on Stem Cell-Derived Extracellular Vesicles toward Neuropathy Applications

The peripheral nervous system undergoes sufficient stress when affected by diabetic conditions, chemotherapeutic drugs, and personal injury. Consequently, peripheral neuropathy arises as the most common complication, leading to debilitating symptoms that significantly alter the quality and way of life. The resulting chronic pain requires a treatment approach that does not simply mask the accompanying symptoms but provides the necessary external environment and neurotrophic factors that will effectively facilitate nerve regeneration. Under normal conditions, the peripheral nervous system self-regenerates very slowly. The rate of progression is further hindered by the development of fibrosis and scar tissue formation, which does not allow sufficient neurite outgrowth to the target site. By incorporating scaffolding supplemented with secretome derived from human mesenchymal stem cells, it is hypothesized that neurotrophic factors and cellular signaling can facilitate the optimal microenvironment for nerve reinnervation. However, conventional methods of secretory vesicle production are low yield, thus requiring improved methods to enhance paracrine secretions. This report highlights the state-of-the-art methods of neuropathy treatment as well as methods to optimize the clinical application of stem cells and derived secretory vesicles for nerve regeneration.

The intervention effect of psychological care combined with ondansetron, dexamethasone, and promethazine hydrochloride on chemotherapy in breast cancer surgical patients

BACKGROUND

Breast cancer (BC) is one of the most common malignancies in women and imposes a significant health burden globally. According to data from the World Health Organization, the incidence of BC has been increasing steadily over the years. It has become one of the leading causes of cancer-related death among women worldwide.

OBJECTIVE

This work was to evaluate the combined intervention effect of psychological care along with the use of ondansetron, dexamethasone, and promethazine hydrochloride in breast cancer (BC) patients undergoing chemotherapy, including their impact on nausea and vomiting control, quality of life (QoL), and psychological status.

METHODS

64 BC patients undergoing chemotherapy were collected and randomly rolled into a control group (Group C) and an intervention group (Group I). Group C received ondansetron combined with routine psychological support and counseling therapy, while Group I received a combination of ondansetron, dexamethasone, promethazine hydrochloride, and psychological care therapy. Self-assessment scores for anxiety, QoL ratings, white blood cell counts, and incidence of adverse reactions were assessed and compared between the two groups.

RESULTS

Group I showed better control of nausea and vomiting versus Group C (P< 0.05). Marked improvements were also observed in the self-rating anxiety scale (SAS) scores, white blood cell counts, and nursing satisfaction in Group I versus Group C (P< 0.05). Nevertheless, the two groups had no significant difference regarding QoL scores (P> 0.05).

CONCLUSION

the combination of psychological care with ondansetron, dexamethasone, and promethazine hydrochloride effectively controls nausea and vomiting symptoms in BC patients undergoing chemotherapy and provides higher levels of clinical nursing satisfaction.

Overview of premedication prescription and intake in an oncology day hospital: What do we need to change to improve patient management?

BACKGROUND

Premedication of cancer therapy against nausea and vomiting (NV) and hypersensitivity reaction (HS) is essential for good patient management. However, this prescription is not always optimal. Today, as a large part of cancer therapies are administered in day hospitals (DH), premedication taken on the day of the cancer treatment is injected as a 30-min infusion.

OBJECTIVE

To assess compliance with recommendations for premedication prescription and intake; to analyse patient attitude about switching to exclusively oral forms taken at home.

METHOD

The study is conducted in the medical oncology DH of a French Hospital from 17 January to 25 February 2022. The data collection is carried out as an individual interview, associated with the distribution of two questionnaires. Data are coupled with the premedication set up on our software and the last medical report. Intakes are considered optimal when recommendations, tolerance, background, and adherence of the patient are taken into account.

RESULTS

Seventy patients were included for interviews. Regarding software prescriptions, our configuration was consistent with recommendations in 100% of cases for HS and 37% for NV. Intakes were compliant in 51.4% of cases, non-compliant in 17.1% and debatable in 31.5%. Disparities between the practices of different physicians were identified. Regarding the feasibility of oral substitution, it could concern 63.5% of patients.

CONCLUSION

This work makes it possible to improve the management of all patients and to make the operation of the care unit more fluid.

Effect of Aprepitant on Etoposide Pharmacokinetics in Patients with Testicular Cancer: A Pharmacokinetic Study to Determine the Absence of a Clinically Relevant Interaction

All patients treated with anticancer agents should receive the most effective anti-emetic regimen. Anti-emetic guidelines provide recommendations but do not take into account possible drug-drug interactions between anti-emetics and anticancer drugs. This study determines the clinical relevance of the potential drug-drug interaction of the neurokinin-1 receptor antagonist, aprepitant, on the pharmacokinetics of etoposide. Aprepitant is a moderate CYP3A4 inhibitor and may increase the systemic exposure of etoposide which is partly metabolized by cytochrome P450 enzyme 3A4 (CYP3A4). In this prospective observational study, the pharmacokinetics of etoposide with and without concomitant use of aprepitant was determined in 12 patients receiving first-line chemotherapy for testicular cancer. The geometric mean (95% confidence interval (CI)) area under the plasma concentration-time curve 0-24 hour (AUC0-24h ) of etoposide with aprepitant was 86.2 (79.7-93.2) mg/L*hour vs. 83.7 (75.8-92.4) mg/L*hour without aprepitant. Geometric mean ratios (90% CIs) of AUC0-24h and maximum plasma concentration (Cmax ) for etoposide with and without aprepitant were 1.03 (0.96-1.10) and 0.96 (0.89-1.03), respectively. This study confirms the absence of a clinically relevant interaction between etoposide and aprepitant. Both drugs can be safely combined without affecting etoposide exposure.

Awareness and interest in cannabis use for cancer management among cancer survivors

BACKGROUND

We examined the awareness, interest, and information sources relating to cannabis use for cancer management (including management of cancer symptoms and treatment-related side effects) and determined factors associated with cancer survivors' awareness and interest in learning about cannabis use for cancer management.

METHODS

This was a cross-sectional study of adult cancer survivors (N = 1886) receiving treatment at a comprehensive cancer center. Weighted prevalence and multivariable logistic regression analyses were conducted.

RESULTS

Among cancer survivors, 88% were aware and 60% were interested in learning about cannabis use for cancer management. Common sources of information to learn about cannabis use for cancer management were cancer doctors/nurses (82%), other patients with cancer (27%), websites/blogs (26%), marijuana stores (20%), and family/friends (18%). The odds of being aware of cannabis use for cancer management was lower among male compared to female survivors (adjusted odds ratio [AOR]: 0.61; 95% confidence interval [CI]: 0.41-0.90), non-Hispanic Blacks compared to non-Hispanic Whites (AOR: 0.36; 95% CI: 0.21-0.62), and survivors who do not support the legalization of cannabis for medical use compared to those who do (AOR: 0.10; 95% CI: 0.04-0.23). On the other hand, the odds of being interested in cannabis use for cancer management was higher among non-Hispanic Blacks compared to non-Hispanic Whites (AOR: 1.65; 95% CI: 1.04-2.62), and among cancer survivors actively undergoing cancer treatment compared to patients on non-active treatment (AOR: 2.25; 95% CI: 1.74-2.91).

CONCLUSION

Awareness of cannabis use for cancer management is high within the cancer survivor population. Results indicated health care providers are leading information source and should receive continued medical education on cannabis-specific guidelines. Similarly, tailored educational interventions are needed to guide survivors on the benefits and risks of cannabis use for cancer management.

The impact of drug-eluting bead (vs. conventional) transarterial chemoembolization on hepatic fibrosis in treating intermediate or advanced hepatocellular carcinoma

OBJECTIVE

Limited studies have reported the impact of drug-eluting bead transarterial chemoembolization (DEB-TACE) on hepatic fibrosis in hepatocellular carcinoma (HCC). This study evaluated multiple hepatic fibrosis indicators, aiming to comprehensively compare the influence of DEB-TACE and conventional transarterial chemoembolization (cTACE) on hepatic fibrosis in treating HCC patients.

METHODS

Intermediate/advanced HCC patients (N = 121) were divided into the DEB-TACE group (n = 62) and the cTACE group (n = 59) based on their chosen treatment. Serum hyaluronic acid (HA), pro-collagen type-III (PC-III), collagen type-IV (IV-C), and laminin (LN) were detected; aminotransferase to platelet ratio index (APRI) and fibrosis index based on the four factors (FIB-4) were calculated; liver stiffness measurement (LSM) was assessed by real-time shear wave elastography.

RESULTS

HA, PC-III, IV-C, and LN at 1 month after the second TACE and at 12 months after the first TACE were all decreased in DEB-TACE group compared with cTACE group (all P < .050). Then, APRI, FIB-4, and LSM were further assessed, which also showed a decreasing trend at aforementioned timepoints in DEB-TACE group compared with cTACE group (all P < .050). Additionally, the multivariate logistic regression analysis revealed that DEB-TACE (vs. cTACE) was independently associated with reduced occurrence of severe hepatic fibrosis at 12 months (OR = 0.215, 95%CI: 0.058-0.802, P = .022). Concerning the liver function indexes, alanine aminotransferase, aspartate aminotransferase, and total bilirubin after treatment were not different between the two groups (all P > .050).

CONCLUSION

DEB-TACE displays attenuated hepatic fibrosis progression and noninferior tolerance compared to cTACE in treating intermediate- or advanced-stage HCC patients.

Integrative Approaches in the Treatment of Patients Affected by Lymphoma

PURPOSE OF REVIEW

Lymphoma is the most frequent hematological malignancy with wide disease spectrum of watchful waiting period, active treatment, survivorship, and palliative care. All these steps impose unmet needs in terms of prevention, symptom alleviation, or prognosis. Complementary and integrative medicine (CIM) is widely used by patients with lymphoma to cope with such issues. Here, we describe the different CIM modalities that may be effective and safe for the management of patients with lymphoma.

RECENT FINDINGS

Low inflammatory diet and ginseng seem effective for lymphoma prevention. Pain and neuropathy may be improved using acupuncture, touch therapy and specific dietary supplements. Nausea/vomiting, fatigue, and insomnia may be relieved by acupuncture, mind-body, touch therapy, and certain dietary supplements. Vitamin D, curcumin, and some traditional medicine herbs may positively impact lymphoma prognosis. Finally, safety issues should be considered especially for the concomitant use of dietary supplements and lymphoma-directed therapies. CIM may be beneficial along the continuum of lymphoma management although safety concerns should be considered when used concomitantly with conventional therapy.

Application Value of Antimicrobial Peptides in Gastrointestinal Tumors

Gastrointestinal cancer is a common clinical malignant tumor disease that seriously endangers human health and lacks effective treatment methods. As part of the innate immune defense of many organisms, antimicrobial peptides not only have broad-spectrum antibacterial activity but also can specifically kill tumor cells. The positive charge of antimicrobial peptides under neutral conditions determines their high selectivity to tumor cells. In addition, antimicrobial peptides also have unique anticancer mechanisms, such as inducing apoptosis, autophagy, cell cycle arrest, membrane destruction, and inhibition of metastasis, which highlights the low drug resistance and high specificity of antimicrobial peptides. In this review, we summarize the related studies on antimicrobial peptides in the treatment of digestive tract tumors, mainly oral cancer, esophageal cancer, gastric cancer, liver cancer, pancreatic cancer, and colorectal cancer. This paper describes the therapeutic advantages of antimicrobial peptides due to their unique anticancer mechanisms. The length, net charge, and secondary structure of antimicrobial peptides can be modified by design or modification to further enhance their anticancer effects. In summary, as an emerging cancer treatment drug, antimicrobial peptides need to be further studied to realize their application in gastrointestinal cancer diseases.

Phase 1b safety and pharmacokinetics of intravenous and oral fosmanogepix in patients with acute myeloid leukaemia and neutropenia

OBJECTIVES

Fosmanogepix (APX001), a first-in-class, intravenous (IV) and oral (PO) antifungal prodrug, is being developed to treat invasive fungal diseases (IFDs). Manogepix (APX001A; active moiety) targets fungal glycosylphosphatidylinositol-anchored cell wall transfer protein 1, inhibiting cell wall synthesis causing loss of viability. This open-label, multicentre, Phase 1b study in patients with AML and neutropenia (absolute neutrophil count <500 cells/μL; >10 days) undergoing chemotherapy aimed to assess tolerability, safety and pharmacokinetics (PK) of IV and PO fosmanogepix.

METHODS

Of 21 adult AML patients undergoing remission induction chemotherapy, 10 received IV fosmanogepix (600 mg; q24h) and 11 received oral fosmanogepix (500 mg; q24h) over 14 days, with a 28 day follow-up. Patients also received remission induction chemotherapy [sequential high-dose cytarabine and mitoxantrone (S-HAM) or 7 + 3 regimen] for AML and IFD prophylaxis (posaconazole). A two-compartmental PK model from previous studies in healthy volunteers was fitted to manogepix plasma data.

RESULTS

Of 26 fosmanogepix-related adverse events (AEs; IV: 14; PO: 12) in 9 (42.9%) patients [IV: 5 (50%); PO: 4 (36.4%)], none were serious or resulted in fosmanogepix discontinuation. Most frequently occurring fosmanogepix-related AEs were Grade 1/2 nausea [four events in three patients (14.3%)]; vomiting, ALT increase, and delirium [two events; two patients (9.5%) each]. One patient experienced fosmanogepix-related Grade 3 hypertension. Dose-corrected geometric mean ratio of AUC (PO-to-IV) was 95%. Elimination half-lives (∼2 days) were consistent with prior studies in healthy volunteers.

CONCLUSIONS

Fosmanogepix was safe and well tolerated in AML patients with neutropenia receiving remission induction chemotherapy. Safety and PK profiles were comparable to healthy volunteers.

Pooled Analysis of Studies Evaluating Fosnetupitant and Risk Factors for Cisplatin-Induced Nausea and Vomiting During the Extended Overall Phase

INTRODUCTION

Fosnetupitant is a novel neurokinin 1 receptor antagonist (NK1RA) with favorable antiemetic efficacy in patients receiving emetogenic chemotherapy. This study assessed the efficacy of fosnetupitant in combination with palonosetron and dexamethasone and identified risk factors for chemotherapy-induced nausea and vomiting (CINV) for up to 168 h after treatment using pooled data from Japanese studies.

METHODS

A pooled analysis of randomized phase II and phase III studies was performed to compare the efficacy of fosnetupitant and fosaprepitant in patients receiving cisplatin-based chemotherapy. The complete response (CR; no vomiting and no rescue medication) rate, CINV risk factors in various phases (0-120, 0-168, and 120-168 h), and impact of the number of risk factors on the time to treatment failure (TTF) were examined in the overall and NK1RA evaluable populations.

RESULTS

In the combined cohort of NK1RA evaluable patients (n = 980), the CR rate at 0-168 h was significantly better in the fosnetupitant 235 mg group than in the fosaprepitant group (rate difference = 6.8%, 95% confidence interval = 1.0-12.7, p = 0.022). In the overall (n = 1368) and NK1RA evaluable populations, the CINV risk factor at 120-168 h was treatment failure in the first 120 h. TTF deteriorated as the number of identified CINV risk factors increased.

CONCLUSION

This analysis revealed that fosnetupitant could have long-acting antiemetic potency (> 120 h) and indicated the importance of antiemetic therapy at 0-120 h for CINV up to 168 h after chemotherapy.

Retrospective Evaluation of a Dexamethasone Sparing Antiemetic Regimen: An Antiemetic Prophylaxis Study on NEPA (Netupitant Plus Palonosetron) for Preventing Chemotherapy-Induced Nausea and Vomiting (CINV) in Cancer Patients

Background Corticosteroids, specifically dexamethasone (DEX), have been extensively utilized for the prevention of chemotherapy-induced nausea and vomiting (CINV). However, their usage is associated with a range of adverse events. In contrast, the combination of Netupitant Plus Palonosetron (NEPA) with a single dose of DEX provides comparable efficacy in preventing CINV over a five-day period following chemotherapy administration. This regimen offers the advantage of reducing the need for additional doses of DEX, particularly in the high-risk setting of HEC (Highly emetic chemotherapy). Objective To evaluate dexamethasone sparing anti-emetic regimen (single dose dexamethasone with NEPA) for prophylaxis of CINV in patients receiving HEC. Methodology This is a retrospective, observational, real-world, single-center study including data of 69 patients who received high-dose emetogenic chemotherapy and were administered DEX (8 or 12 mg) on day 1, with no dose of DEX on days 2, 3, and 4, combined with an oral combination of tablet netupitant 300 mg and palonosetron 0.5 mg. NEPA was taken orally an hour prior to the start of the HEC cycle. The primary efficacy endpoint was complete response (CR) which is defined as no nausea, emesis, or no rescue medication during the Acute (< 24 hours) and Delayed Phase (25-120 hours) of chemotherapy. Results The overall CR achieved in the acute and delayed phase for vomiting is 100% at all four follow-ups. The CR achieved in the acute phase is 95.7% whereas 98.6% of patients showed CR in the delayed phase respectively. No patient required any rescue medication. No acute and delayed phase of vomiting was reported. Conclusion A simplified regimen of NEPA plus single-dose DEX offers effective CINV prevention throughout five days post-chemotherapy with the advantage of sparing patients additional doses of DEX in the high-emetic-risk setting chemotherapy.

Cardiac Toxicities in Oncology: Elucidating the Dark Box in the Era of Precision Medicine

Despite current advancements in chemotherapy, immunotherapy and targeted treatments, the potential for major adverse cardiovascular events, regardless of previous cardiac history, persists. Scoring systems, such as the Heart Failure Association-International Cardio-Oncology Society (HFA-ICOS) risk assessment tool, can be utilized to evaluate several factors including prior cardiac history, risk factors and cardiac biomarkers to categorize patients into low, moderate, high, and very high-risk groups. Common cardiotoxicity complications include new or worsening left ventricular ejection fraction (LVEF), QT interval prolongation, myocardial ischaemia, hypertension, thromboembolic disease, cardiac device malfunction and valve disease. Baseline electrocardiogram (ECG) and transthoracic echocardiogram (TTE) are routinely performed for all patients commenced on cardiotoxic treatment, while other imaging modalities and biochemical markers have proven useful for monitoring. Management mainly includes early risk stratification and prompt identification of cardiovascular complications, with patient-specific surveillance throughout treatment. A multidisciplinary approach is crucial in determining the relationship between potential treatment benefits and cardiotoxicity, and whether the continuation of treatment is appropriate on a case-by-case basis. Early risk stratification, optimizing the patient's cardiovascular status prior to treatment, and prompt identification of suspected cardiotoxicity are key in significantly reducing risk. This article provides a comprehensive review of the various types of treatment-related cardiotoxicity, offering guidance on identifying high-risk patients, recognizing early signs of cardiotoxicity, and outlining appropriate treatment approaches and follow-up care for such cases.

Application of traditional Chinese medicine acupoint needle embedding combined with emotional nursing in patients with gynecological malignant tumors

BACKGROUND

Few relevant literature reports on applying acupoint press-needle embedding combined with emotional nursing in patients with a gynecological malignant tumor.

AIM

To explore the effect of traditional Chinese medicine acupoint needle embedding combined with emotional nursing on chemotherapy-related nausea and vomiting (CINV), cancer-related fatigue (CRF) and psychological state in patients with gynecological malignant tumors.

METHODS

Retrospective analysis of the clinical information of 84 patients with gynecological malignant tumors treated in our hospital from August 2020 to December 2022 Led to the development of an observation group (n = 42) and a control group (n = 42) based on various nursing approaches. Ondansetron hydrochloride injection was administered to the individuals in the control group. However, the observation group received emotional nursing based on the control group and acupoint press-needle embedding of traditional Chinese medicine. Patients in both groups received the chemotherapy regimen of paclitaxel liposome + carbo-platin/ cisplatin. For four weeks, both groups intervened. The CINV grade, quality of life, CRF, psychological status and sleep quality scores of the two groups before and after intervention were compared.

RESULTS

After intervention, the degree of CINV in the observation group was significantly better than that in the control group. After intervention, the scores of each dimension and total score of FLIE scale were significantly higher than those in the control group. After intervention, the scores of each dimension and total score of Piper Fatigue Scale were significantly lower than those in the control group (P < 0.05). After intervention, the scores of avoidance and yield dimensions in the observation group were significantly lower than those in the control group, and the scores of confrontation dimension were significantly higher than those in the control group (P < 0.05). After intervention, the sleep quality score of the observation group was significantly lower than that of the control group, and the Karnofsky Performance Status scale score was significantly higher than that of the control group (P < 0.05).

CONCLUSION

The acupuncture point needle embedding of traditional Chinese medicine combined with emotional nursing can further reduce the incidence of chemotherapy-related nausea and vomiting in patients with gynecological malignant tumors, improve the quality of life and the degree of CRF, alleviate the bad psychological state, adopt a positive way to face the disease and treatment, and improve the quality of sleep and quality of life.

Fertility Preservation in Children and Adolescents during Oncological Treatment-A Review of Healthcare System Factors and Attitudes of Patients and Their Caregivers

Oncofertility is any therapeutic intervention to safeguard the fertility of cancer patients. Anti-cancer therapies (chemotherapy, radiation therapy, etc.) entail the risk of reproductive disorders through cytotoxic effects on gamete-building cells, especially those not yet fully developed. This literature review analyzes the available data on securing fertility in pediatric and adolescent populations to identify the methods used and describe aspects related to financing, ethics, and the perspective of patients and their parents. Topics related to oncofertility in this age group are relatively niche, with few peer-reviewed articles available and published studies mostly on adults. Compared to pubertal individuals, a limited number of fertility preservation methods are used for prepubertal patients. Funding for the procedures described varies from country to country, but only a few governments choose to reimburse them. Oncofertility of pediatric and adolescent patients raises many controversies related to the decision, parents' beliefs, having a partner, ethics, as well as the knowledge and experience of healthcare professionals. As the fertility of young cancer patients is at risk, healthcare professionals should make every effort to provide them with an opportunity to fulfill their future reproductive plans and to have a family and offspring. Systemic solutions should form the basis for the development of oncofertility in pediatric and adolescent populations.

Effectiveness of antiemetic in reducing chemotherapy-induced nausea and vomiting in adult patients; An oncology center experience

INTRODUCTION

Chemotherapy-induced nausea and vomiting (CINV) are two serious adverse effect of cancer chemotherapy. The objectives of this study are to assess patient satisfaction with antiemetics prescribed, incidence of nausea and vomiting in cancer patients, and the effectiveness of antiemetic regimens in reducing CINV.

METHODS

This is a prospective observational cross-sectional patient survey study, conducted between January and July 2021 in the oncology center at King Saud University Medical City, Riyadh, Saudi Arabia. A suitable, data entry form was designed to collect data including patient demographics, cancer type, antiemetics prescribed, chemotherapy regimen, and incidence of CINV.

RESULTS

The sample comprised 283 cancer patients with a mean age of 47.7 (±14.6) years. Colorectal and breast cancer (n = 67; 23.6%, for each) were the two most common diagnoses. Among the patients who received chemotherapy, most patients (n = 144; 50.8%) received chemotherapy that was classified as highly emetogenic, and 139 (49%) received moderately emetogenic chemotherapy. Antiemetics were given to control CINV before chemotherapy administration (as prophylaxis) were either combination therapy (170 patients (60.0%) received four classes of antiemetics, 72 (25.4%) received three classes; and 31 (10.9%) received two classes) or monotherapy (six patients (2.1%) received one drug). Four patients (1.4%) did not receive any antiemetic medication. Antiemetics given to control CINV after chemotherapy administration (for delayed CINV) were also either in combination (151 patients (53.3%) received three classes of antiemetics and 94 (33.2%) received two classes) or as monotherapy, where 27 patients (9.5%) received one medication. Eleven patients (3.8%) did not receive any antiemetic. The incidence rates for acute and delayed nausea after chemotherapy treatment were 32.1% and 30.7%, respectively; and those for acute and delayed vomiting were 13.4% and 10.2%, respectively. Acute nausea was much more frequent than vomiting.

CONCLUSION

The incidence of CINV was relatively high, and patients who received chemotherapy continued to experience nausea and vomiting despite receiving antiemetic treatment. This demonstrates that antiemetic regimens used are not effective in preventing CINV.

Oral Tetrahydrocannabinol (THC):Cannabinoid (CBD) Cannabis Extract Adjuvant for Reducing Chemotherapy-Induced Nausea and Vomiting (CINV): A Randomized, Double-Blinded, Placebo-Controlled, Crossover Trial

Objective

To evaluate the effects of tetrahydrocannabinol (THC):cannabinoid (CBD) (1:1) oil in reducing chemotherapy-induced nausea and vomiting (CINV) in gynecologic cancer patients who received moderate-to-high emetogenic chemotherapy.

Material and Method

This was a randomized, double-blinded, crossover and placebo-controlled trial. The study was conducted at the Gynecologic Oncology Units, Bhumibol Adulyadej Hospital (BAH), Royal Thai Air Force, Bangkok, Thailand, between August and November 2022. Participants had gynecologic cancer and received moderate-to-high emetogenic chemotherapy. Subjects were randomized and divided into two groups (A and B) based on the block of four randomization method. In the first cycle, groups A and B received THC:CBD extract oil 1:1 (TCEO) and placebo before chemotherapy administration. In the second cycle, groups A and B received placebo and TCEO before chemotherapy administration. Both groups received per protocol antiemetic medication during chemotherapy. Nausea score and side effects were recorded.

Results

A total of 60 cases were recruited. After exclusion, 54 cases were included in the study. The mean age of participants was 54.4 years. The mean body mass index (BMI) was 26.5 kg/m2. Fifty-nine (21/54) percent cases were the advanced stages of cancer. The nausea score of TCEO and placebo groups were 2.11 and 2.99, respectively (P < 0.05). More than half of the participants (36/54) reported dizziness and sedation side effects. Dry mouth, confusion, anxiety, and palpitation of both groups were comparable.

Conclusion

The cannabinoid extract (THC:CBD) was an appropriate adjuvant agent to reduce CINV in patients with gynecologic cancer who received high-emetogenic chemotherapy. Dizziness and sedation were the major side effects.

Age-related differences in the occurrence, severity, and distress of symptoms in older patients at the initiation of chemotherapy

BACKGROUND

Evaluate for differences in occurrence, severity, and distress ratings for 32 symptoms between younger older adults (YOA, < 70 years) and older adults (OA, ≥ 70 years) at initiation of chemotherapy.

METHODS

Patients (n = 125) were recruited prior to the initiation of chemotherapy and completed the Memorial Symptom Assessment Scale. Differences in occurrence, severity, and distress ratings were evaluated using Independent sample t-tests and Chi-square or Fisher's exact tests.

RESULTS

On average, the older patients reported ten concurrent symptoms that equates with a moderate symptom burden. Symptoms with the highest occurrence rates were not always the most severe and/or the most distressing. Few age-related differences were found in patients' symptom experiences. When age-related differences were identified, OA reported lower occurrence, severity, and distress ratings. Nine of the ten symptoms with highest occurrence rates were common for both age groups. For severity and distress, only half of the symptoms were common. In terms of severity and distress, all of the top ten ranked symptoms were in the moderate to severe range.

CONCLUSIONS

Both YOA and OA reported a moderate symptom burden and severity and distress scores in the moderate to severe range. The symptoms with the highest occurrence rates were not always the most severe/or the most distressing. Our findings suggest that different dimensions of the symptom experience (i.e., occurrence, severity, and distress) warrant evaluation in older oncology patients.

Should oncologists trust cannabinoids?

Cannabis enjoyed a "golden age" as a medicinal product in the late 19th, early 20th century, but the increased risk of overdose and abuse led to its criminalization. However, the 21st century have witnessed a resurgence of interest and a large body of literature regarding the benefits of cannabinoids have emerged. As legalization and decriminalization have spread around the world, cancer patients are increasingly interested in the potential utility of cannabinoids. Although eager to discuss cannabis use with their oncologist, patients often find them to be reluctant, mainly because clinicians are still not convinced by the existing evidence-based data to guide their treatment plans. Physicians should prescribe cannabis only if a careful explanation can be provided and follow up response evaluation ensured, making it mandatory for them to be up to date with the positive and also negative aspects of the cannabis in the case of cancer patients. Consequently, this article aims to bring some clarifications to clinicians regarding the sometimes-confusing various nomenclature under which this plant is mentioned, current legislation and the existing evidence (both preclinical and clinical) for the utility of cannabinoids in cancer patients, for either palliation of the associated symptoms or even the potential antitumor effects that cannabinoids may have.

Real-World Treatment Outcomes, Healthcare Resource Use, and Costs Associated with Antiemetics Among Cancer Patients on Cisplatin-Based Chemotherapy

INTRODUCTION

Chemotherapy-induced nausea and vomiting (CINV) is a recognized adverse outcome among patients with cancer. This retrospective study aimed to quantify the treatment outcomes, resource utilization, and costs associated with antiemetic use to prevent CINV in a broad US population who received cisplatin-based chemotherapy.

METHODS

Data from the STATinMED RWD Insights Database was collected from January 1, 2015 to December 31, 2020. Cohorts included any patients that had at least one claim for fosnetupitant + palonosetron (NEPA) or fosaprepitant + palonosetron (APPA) and evidence of initiating cisplatin-based chemotherapy. Logistic regression was used to evaluate nausea and vomiting visits within 14 days after chemotherapy, and generalized linear models were used to examine all-cause and CINV-related healthcare resource utilization (HCRU) and costs.

RESULTS

NEPA was associated with significantly lower rates of nausea and vomiting visits after chemotherapy (p = 0.0001), including 86% greater odds of nausea and vomiting events for APPA during the second week after chemotherapy (odds ratio [OR] = 1.86; p = 0.0003). The mean numbers of all-cause inpatient visits (p = 0.0195) and CINV-related inpatient and outpatient visits were lower among NEPA patients (p < 0.0001). These differences corresponded to 57% of NEPA patients and 67% of APPA patients having one or more inpatient visits (p = 0.0002). All-cause outpatient costs and CINV-related inpatient costs were also significantly lower for NEPA (p < 0.0001). The mean number of all-cause outpatient visits, all-cause inpatient costs, and CINV-related outpatient costs was not significantly different between groups (p > 0.05).

CONCLUSION

In this retrospective study based on claims data, NEPA was associated with lower rates of nausea and vomiting and lower CINV-related HCRU and costs compared to APPA following cisplatin-based chemotherapy. These results complement clinical trial data and published economic models supporting the use of NEPA as a safe, effective, and cost-saving antiemetic for patients undergoing chemotherapy.

Combination of thalidomide and Clostridium butyricum relieves chemotherapy-induced nausea and vomiting via gut microbiota and vagus nerve activity modulation

Nausea and vomiting (CINV) are distressful and widespread side effects of chemotherapy, and additional efficient regimens to alleviate CINV are urgently needed. In the present study, colorectal cancer (CRC) mice model induced by Azoxymethane (AOM)/Dextran Sodium Sulfate (DSS) was employed to evaluate the cancer suppression and CINV amelioration effect of the combination of thalidomide (THD) and Clostridium butyricum. Our results suggested that the combination of THD and C. butyricum abundantly enhanced the anticancer effect of cisplatin via activating the caspase-3 apoptosis pathway, and also ameliorated CINV via inhibiting the neurotransmitter (e.g., 5-HT and tachykinin 1) and its receptor (e.g., 5-HT₃R and NK-1R) in brain and colon. Additionally, the combination of THD and C. butyricum reversed the gut dysbacteriosis in CRC mice by increasing the abundance of Clostridium, Lactobacillus, Bifidobacterium, and Ruminococcus at the genus level, and also led to increased expression of occludin and Trek1 in the colon, while decreased expression of TLR4, MyD88, NF-κB, and HDAC1, as well as the mRNA level of IL-6, IL-1β, and TNF-α. In all, these results suggest that the combination of THD and C. butyricum had good efficacy in enhancing cancer treatments and ameliorating CINV, which thus provides a more effective strategy for the treatment of CRC.

Effectiveness of Palonosetron, 1-Day Dexamethasone, and Aprepitant in Patients Undergoing Carboplatin-Based Chemotherapy

INTRODUCTION

Dexamethasone (DEX)-sparing strategy with 5-hydroxytryptamine-3 receptor antagonist (5HT3RA) and aprepitant (APR), as triplet antiemetic prophylaxis, is associated with poor control of delayed chemotherapy-induced nausea and vomiting (CINV) in patients receiving carboplatin (CBDCA)-based chemotherapy. This study aimed to evaluate whether using palonosetron (PALO) as a 5HT3RA provides superior control with CINV than first-generation (1st) 5HT3RA in triplet antiemetic prophylaxis with a DEX-sparing strategy.

METHODS

Pooled patient-level data from a nationwide, multicenter, and prospective observational study were analyzed to compare the incidence of CINV between patients administered PALO and 1st 5HT3RA in combination with 1-day DEX and APR.

RESULTS

No significant differences were observed in the incidence of CINV, pattern of CINV, or severity of nausea by type of 5HT3RA in triplet antiemetic prophylaxis with DEX-sparing strategy. In both groups, the incidence of nausea gradually increased from day 3, peaked on day 4 or 5, and then declined slowly. The visual analog scale scores in the delayed phase remained high throughout the 7-day observation period.

CONCLUSION

Careful patient selection and symptom monitoring are needed when implementing the DEX-sparing strategy in triplet antiemetic prophylaxis for patients undergoing CBDCA-based chemotherapy. Furthermore, additional strategies may be needed to achieve better control of delayed CINV.

Fosnetupitant for the Prevention of Chemotherapy-Induced Nausea and Vomiting: A Short Review and Clinical Perspective

Chemotherapy-induced nausea and vomiting (CINV) is often ranked by patients as one of the most distressing and feared consequences of chemotherapy. The novel neurokinin-1 (NK1) receptor antagonist fosnetupitant, a phosphorylated prodrug formulation of netupitant, was approved in Japan in 2022. Fosnetupitant is one of the standard treatments for the prevention of CINV in patients who are receiving highly (any treatment where CINV occurs in more than 90% of patients) or moderately (where CINV occurs in 30-90% of patients) emetogenic chemotherapies. The aim of this commentary is to describe the mechanism of action, tolerability, and antiemetic efficacy of single-agent fosnetupitant in the prevention of CINV, and to discuss its clinical application, in order to aid optimal use.
