Two doses of fosaprepitant included prophylactic treatment for the three-day cisplatin-based chemotherapy induced nausea and vomiting.

PURPOSE: Neurokinin 1 receptor antagonists included prophylactic treatment was recommended for patients who receive one-day cisplatin chemotherapy. It is unclear whether the prolonged administration of fosaprepitant is effective for three-day cisplatin-based chemotherapy induced nausea and vomiting (CINV). We aim to explore the prophylactic antiemetic efficacy and safety of two doses of fosaprepitant included regimen in the patients receiving multiple-day cisplatin chemotherapy. METHODS: This randomized, parallel-group, open-labelled study was conducted in nine hospitals between February 2021 and February 2023. Patients diagnosed as lung cancer and chemotherapy naive were screened. Eligible participants were scheduled to be treated with highly emetogenic chemotherapy regimen which including three days of cisplatin. Then they were randomly divided into the experimental group (two doses of fosaprepitant, Group 2DF) and the control group (one dose of fosaprepitant, Group C). The primary endpoints included the safety and the average none CINV days (NCDs). This study was registered on the website of chictr.org.cn, number ChiCTR2100042665. RESULTS: Overall, 204 participants were randomly assigned, and 198 patients were analyzed. No statistical difference in adverse events was found between the two groups. All treatment-related adverse effects for fosaprepitant observed were of grade 1-2. The average NCDs of Group 2DF was significantly more than Group C (18.21 ± 3.40 days vs 16.14 ± 5.20 days, P = 0.001). Furthermore, the better life function score was achieved in Group 2DF according to FLIE questionnaire. CONCLUSION: The administration of two-dose fosaprepitant was safe and more effective than one dose in protecting patients from CINV induced by three-day cisplatin included chemotherapy.

Randomized Placebo-Controlled Trial of Topical Capsaicin for Delayed Chemotherapy-Induced Nausea and Vomiting.

PURPOSE: We examined the efficacy of topical capsaicin in reducing delayed chemotherapy-induced nausea and vomiting (CINV). METHODS: Adults on highly emetogenic chemotherapy regimens applied 2 g of capsaicin ointment (0.075%) or matching placebo four times a day to the abdomen for 5 days in addition to standard antiemetic regimen in this blinded randomized controlled trial. Patients were monitored for nausea and vomiting in the immediate (day 1), delayed (days 2-5), and extended phases (days 2-15). Self-reported incidence and daily episodes of CINV were compared between the groups. Onset, severity, need for rescue antiemetics, cumulative vomiting episodes, and safety were also compared. RESULTS: In total, 160 patients were enrolled. The final modified intention-to-treat population included 75 patients each in the capsaicin and placebo groups. Fewer patients experienced nausea (36.0% [n = 27] v 53.3% [n = 40]; P = .033) and vomiting (28.0% [n = 21] v 42.7% [n = 32]; P = .060) in the capsaicin arm during the delayed phase. During the extended phase, there was a significantly lower incidence of nausea (44% v 64.0%; P = .014) in the capsaicin arm. No difference in nausea (26.7% v 25.3%) or vomiting (22.7% v 18.7%) was evident in the immediate phase. The average daily episodes of nausea and vomiting were significantly fewer in the capsaicin arm during the delayed and extended phases. With capsaicin, no grade 3 nausea (9.3% v 0.0%; P = .007) was observed, and the time to first nausea and vomiting was significantly prolonged. There were no differences between the groups with respect to rescue antiemetics, unscheduled hospital visits, and adverse events. CONCLUSION: Topical capsaicin reduced the incidence of nausea and the average number of vomiting episodes during delayed and extended phases without increasing adverse effects.

Outcomes of chemotherapy-induced nausea and vomiting guideline adherence in pediatric and adult patients: a systematic review.

PURPOSE: This study describes chemotherapy-induced nausea and vomiting (CINV) control rates in pediatric and adult patients who did or did not receive guideline-consistent CINV prophylaxis. METHODS: We conducted a systematic literature review of studies published in 2000 or later that evaluated CINV control in patients receiving guideline-consistent vs. guideline-inconsistent CINV prophylaxis and reported at least one CINV-related patient outcome. Studies were excluded if the guideline evaluated was not publicly available or not developed by a professional organization. Over-prophylaxis was defined as antiemetic use recommended for a higher level of chemotherapy emetogenicity than a patient was receiving. RESULTS: We identified 7060 citations and retrieved 141 publications for full-text evaluation. Of these, 21 publications (14 prospective and seven retrospective studies) evaluating guidelines developed by six organizations were included. The terms used to describe CINV endpoints and definition of guideline-consistent CINV prophylaxis varied among studies. Included studies either did not address over-prophylaxis in their definition of guideline-consistent CINV prophylaxis (48%; 10/21) or defined it as guideline-inconsistent (38%; 8/21) or guideline-consistent (3/21; 14%). Eleven included studies (52%; 11/21) reported a clinically meaningful improvement in at least one CINV endpoint in patients receiving guideline-consistent CINV prophylaxis. Ten reported a statistically significant improvement. CONCLUSIONS: This evidence supports the use of guideline-consistent prophylaxis to optimize CINV control. Institutions caring for patients with cancer should systematically adapt CINV CPGs for local implementation and routinely evaluate CINV outcomes.

Pharmacokinetics, pharmacodynamics, safety, and tolerability of dopamine-receptor antagonists for the prevention of chemotherapy-induced nausea and vomiting.

INTRODUCTION: Dopamine (D)2,3-receptor antagonists (RAs) were the first antiemetics used in the prophylaxis of chemotherapy-induced nausea and vomiting (CINV). AREAS COVERED: Eight D2,3-RAs, amisulpride, domperidone, droperidol, haloperidol, metoclopramide, metopimazine, olanzapine and prochlorperazine are reviewed focusing on pharmacokinetics, pharmacodynamics, antiemetic effect and side effects. EXPERT OPINION: Since the introduction of D2,3-RAs, antiemetics such as corticosteroids, 5-hydroxytryptamine (5-HT)3-RAs and neurokinin (NK)1-RAs have been developed. The classical D2,3-RAs are recommended in the prophylaxis of CINV from low emetic risk chemotherapy, but not as a fixed component of an antiemetic regimen for moderately or highly (HEC) emetic risk chemotherapy. D2,3-RAs are also used in patients with breakthrough nausea and vomiting. It should be emphasized, that most of these drugs are not selective for dopamine receptors.The multi-receptor targeting agent, olanzapine, is recommended in the prophylaxis of HEC-induced CINV as part of a four-drug antiemetic regimen, including a 5-HT3-RA, dexamethasone and a NK1-RA. Olanzapine is the most effective agent to prevent chemotherapy-induced nausea.Side effects differ among various D2,3-RAs. Metopimazine and domperidone possess a low risk of extrapyramidal side effects. Domperidone and metoclopramide are prokinetics, whereas metopimazine delays gastric emptying and haloperidol does not influence gastric motility. Many D2,3-RAs increase the risk of prolonged QTc interval; other side effects include sedation and orthostatic hypotension.

Evaluation of Efficacy of Adding Aprepitant to Palonosetron and Dexamethasone in Carboplatin and Etoposide Therapy.

Although carboplatin (CBDCA) is classified as a moderately emetogenic agent, the majority of guidelines recommend the use of a neurokinin-1 receptor antagonist in addition to a 5-hydroxytryptamine type 3 receptor antagonist with dexamethasone (DEX) for CBDCA-containing chemotherapy because of its higher emetogenic risk. However, the additional efficacy of aprepitant (APR) in CBDCA-containing treatment remains controversial, and data on multiple-day treatments are limited. Etoposide (ETP) was administered on days 1-3 in the CBDCA + ETP regimen, and it is important to evaluate suitable antiemetic therapy for the regimen. Therefore, we evaluated the efficacy of additional APR in CBDCA + ETP. Patients were divided into two groups and retrospectively evaluated. One was the control group, which was prophylactically administered palonosetron (PALO) and DEX, and the other was the APR group, which received APR orally with PALO and DEX. The primary endpoint was complete response (CR) between the groups. The overall CR rates were 75.0 and 76.4% in the control and APR groups, respectively, with no significant difference (p = 1.00). In the acute phase, it was 88.9 and 97.2%, respectively, and 86.1 and 79.2% in the delayed phase, respectively, without significant differences (p = 0.10 and 0.38, respectively). The incidence and severity of nausea, vomiting, and anorexia were not significantly different between the two groups in the acute and delayed phases. Our findings suggest that combining APR with PALO and DEX does not improve the CR rate in CBDCA + ETP therapy.

2023 Japan Society of clinical oncology clinical practice guidelines update for antiemesis.

BACKGROUND: The Japan Society of Clinical Oncology Clinical Practice Guidelines for Antiemesis 2023 was extensively revised to reflect the latest advances in antineoplastic agents, antiemetics, and antineoplastic regimens. This update provides new evidence on the efficacy of antiemetic regimens. METHODS: Guided by the Minds Clinical Practice Guideline Development Manual of 2017, a rigorous approach was used to update the guidelines; a thorough literature search was conducted from January 1, 1990, to December 31, 2020. RESULTS: Comprehensive process resulted in the creation of 13 background questions (BQs), 12 clinical questions (CQs), and three future research questions (FQs). Moreover, the emetic risk classification was also updated. CONCLUSIONS: The primary goal of the present guidelines is to provide comprehensive information and facilitate informed decision-making, regarding antiemetic therapy, for both patients and healthcare providers.

A prospective randomized controlled clinical trial investigating the efficacy of low-dose olanzapine in preventing nausea and vomiting associated with oxaliplatin-based and irinotecan-based chemotherapy.

OBJECTIVE: The aim of this study is to assess the clinical efficacy of a 5 mg dosage of olanzapine in preventing chemotherapy-induced nausea and vomiting (CINV) associated with moderately emetogenic chemotherapy (MEC) among female patients diagnosed with gastrointestinal tract tumors. METHODS: Patients undergoing the oxaliplatin/irinotecan chemotherapy regimen were enrolled in this prospective controlled study. The olanzapine group received a 5 mg dosage of olanzapine along with palonosetron and dexamethasone, while the control group received a standard two-combination regimen consisting of dexamethasone and palonosetron. The primary endpoints included the total protection (TP) rates for the entire age group and the subgroup aged 60 years and above. Secondary endpoints encompassed the total protection rates during the acute and delayed phases within the two age brackets, as well as the total control (TC) rates and complete remission (CR) rates across all three phases (total, acute, and delayed). Additionally, the study involved the assessment of quality of life and the collection of adverse events associated with the interventions. RESULTS: 1) Regarding the primary endpoint, the total phase TP rates within both the entire age group and the age group exceeding 60 years demonstrated superiority in the olanzapine group when compared to the control group (66.7% vs 37.25%, P = 0.003; 68.8% vs 44.4%, P = 0.044). 2) In terms of secondary endpoints, the olanzapine group exhibited superior acute phase TP rates in both age brackets when compared to the control group (P < 0.05). The olanzapine group also demonstrated higher delayed-phase TP rates, TC rates across all three phases, and CR rates within the two age brackets, although the differences were not statistically significant (P > 0.05). Furthermore, the quality of life in the olanzapine group surpassed that of the control group for both age brackets (P < 0.05), characterized by enhanced appetite and a higher incidence of drowsiness in the patients treated with olanzapine when compared to those in the control group (P < 0.05). CONCLUSION: Olanzapine can enhance CINV induced by MEC regimen in female patients across all age groups, including the elderly, and therefore improve the quality of life for these patients.

Non-pharmacological treatments for anticipatory nausea and vomiting during chemotherapy: a systematic review and meta-analysis of the Clinical Practice Guidelines for Antiemesis 2023.

BACKGROUND: Anticipatory chemotherapy-induced nausea and vomiting (CINV) is a conditioned response influenced by the severity and duration of previous emetic responses to chemotherapy. We aimed to evaluate the efficacy of non-pharmacologic interventions for anticipatory CINV among patients with cancer. METHODS: We conducted a systematic search in databases, including PubMed, the Cochrane Library, CINAHL, and Ichushi-Web, from January 1, 1990, to December 31, 2020. Randomized controlled trials, non-randomized designs, observational studies, or case-control studies that utilized non-pharmacological therapies were included. The primary outcomes were anticipatory CINV, with an additional investigation into adverse events and the costs of therapies. The risk-of-bias for each study was assessed using the Cochrane risk-of-bias tool, and meta-analysis was performed using Revman 5.4 software. RESULTS: Of the 107 studies identified, six met the inclusion criteria. Three types of non-pharmacological treatments were identified: systematic desensitization (n = 2), hypnotherapy (n = 2), and yoga therapy (n = 2). Among them, systematic desensitization significantly improved anticipatory CINV as compared to that in the control group (nausea: risk ratio [RR] = 0.60, 95% confidence interval [CI] = 0.49-0.72, p < 0.00001; vomiting: RR = 0.54, 95% CI = 0.32-0.91, p = 0.02). However, heterogeneity in outcome measures precluded meta-analysis for hypnotherapy and yoga. Additionally, most selected studies had a high or unclear risk of bias, and adverse events were not consistently reported. CONCLUSIONS: Our findings suggest that systematic desensitization may effectively reduce anticipatory CINV. However, further research is warranted before implementation in clinical settings.

Neiguan (PC6) acupoint stimulation for preventing chemotherapy-induced nausea and vomiting: a cost-effective supplement in guideline-inconsistent chemotherapy-induced nausea and vomiting prophylaxis subgroup.

OBJECTIVE: To assess the efficacy and safety of Neiguan (PC6) acupoint acustimulation in preventing chemotherapy-induced nausea and vomiting (CINV), especially for patients with guideline-inconsistent CINV prophylaxis (GICP) due to personal reasons METHODS: From January 2021 to December 2021, 373 patients suffered from solid malignancy were recruited according to the inclusion criteria. Complete response (no emesis and no rescue medication use) rate during the overall phase (0-120 h of each chemo-cycle) was the primary assessment of CINV control. The Functional Living Index-Emesis (FLIE) questionnaire was investigated among these patients as a secondary 'quality of life' objective to assess the impact of CINV on patients' daily life by recording score of nausea and vomiting. RESULTS: With acustimulation of Neiguan (PC6) acupuncture point through a portable, noninvasive and user-friendly device, in terms of complete response rate and scores in nausea/vomiting by FLIE questionnaire, patients achieve a better outcome in highly emetogenic chemotherapy (HEC) induced CINV, especially GICP subgroup. Meanwhile, analysis also demonstrated this tendency existed in other patients with HEC/GCCP (guideline consistent CINV prophylaxis) and moderate emetogenic chemotherapy, although the difference was not significant. CONCLUSION: Considering advantages of Neiguan (PC6) acustimulation such as noninvasive, covered by medical insurance and few side effects, we believe it would be an ideal auxiliary tool in CINV control, especially in patients who receive highly emetogenic chemo-protocol and are reluctant to GCCP for economic reasons.

MASCC 2023 Patient-Centered Antiemetic Guidelines and Education Statements: an evidence-based and consensus resource for patients.

PURPOSE: The Multinational Association of Supportive Care in Cancer (MASCC)/European Society of Medical Oncology (ESMO) Patient Antiemetic Guideline Committee aimed to (1) adapt the updated evidence-based, clinical guidelines to patient-centered antiemetic guidelines and (2) develop patient education materials and statements. METHODS: The MASCC 2023 Patient Antiemetic Guidelines were created and reviewed by antiemetic experts and patient advocates by incorporating the 2023 MASCC/ESMO antiemetic guidelines into patient-friendly language. Patient Education Statements were developed based on current literature and by utilizing an expert modified Delphi consensus (≥ 75% agreement). Patient advocate/focus group input and patient survey results were further integrated into Patient-Centered Antiemetic Guidelines and Education Statements. RESULTS: Patient-Centered Antiemetic Guidelines were created using patient-friendly language and visual slides. Patient-friendly language was also utilized to communicate the Educational Statements. Key content categories identified for the Educational Statements included the following: nausea/vomiting definitions, causes, risk factors, categories, complications, accompanying symptoms, prophylactic antiemetic treatment, general management, when to call/what to ask the healthcare team, what caregivers can do, and available resources. All identified content met the ≥ 75% expert agreement threshold. Fifteen (15) items demonstrated 100% agreement, 11 items achieved ≥ 90% agreement, and three content items demonstrated 80 ~ 82% agreement. CONCLUSIONS: The inaugural MASCC 2023 Patient Antiemetic Guidelines can help patients and caregivers understand the prevention of nausea and vomiting related to their cancer treatment. Educational Statements provide further patient information. Educating patients on how to utilize guideline antiemetics and the education statements can contribute improvements in the control of anticancer treatment-related nausea and vomiting.

A nurse-led multidomain intervention to improve the management of chemotherapy-induced nausea and vomiting in patients with head and neck cancers: A randomized controlled trial.

PURPOSE: This study aimed to investigate the effect of a nurse-led multidomain intervention on chemotherapy induced nausea and vomiting (CINV) in patients with head and neck squamous cell carcinomas (HNSCC). METHODS: Ninety-two HNSCC patients who received cisplatin-based chemotherapy were divided into intervention group (n = 45) and control group (n = 47). The control group received usual care of CINV, which consisted of administration of antiemetics according to physicians' preference, education about CINV control and dietary recommendations provided by primary nurses. The intervention group received nurse-led, evidence-based multidomain management, including nurse-led CINV risk factors assessment, education on prevention and control of CINV, antiemetics following guidelines, dietary strategies, and relaxation therapy. The number of patients who experienced CINV was collected. The severity of CINV was graded according to the Common Terminology Criteria for Adverse Events v3.0. The influence of CINV on patient's quality of life was assessed by the Functional Living Index-Emesis (FLIE). RESULTS: The incidence and the severity of nausea and vomiting in the intervention group were significantly lower than those in the control group within 5 days after chemotherapy, and the scores of the dimension of nausea and vomiting in the intervention group were significantly higher than those in the control group [63.00 (50.00-63.00) vs 40.00(28.00-63.00), 63.00(63.00-63.00) vs 63.00 (43.00-63.00)], the differences were statistically significant (P < 0.05). CONCLUSIONS: Nurse-led multidomain intervention can reduce the incidence and the severity of CINV in patients with HNSCC who were treated with cisplatin-based chemotherapy, and thus reduced the influence of CINV on patients' quality of life. THE CLINICAL TRIAL REGISTRATION NUMBER: NCT05792228.

Efficacy and safety of netupitant/palonosetron in preventing nausea and vomiting in diffuse large B cell lymphoma patients undergoing R-CHOP chemotherapy.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma, for which cyclophosphamide, doxorubicin, vincristine, and prednisone with rituximab(R-CHOP) is one of the standard regimens. Given that R-CHOP is highly emetogenic, chemotherapy-induced nausea and vomiting (CINV) prevention is clinically important. However, there is a paucity of studies focusing on these patients. This study aimed to ascertain the effectiveness of an oral fixed-dose combination of netupitant and palonosetron (NEPA) in preventing CINV in patients with DLBCL undergoing first-line R-CHOP chemotherapy. Seventy patients were enrolled in this single-center prospective non-comparative study conducted between November 2020 and May 2023 in South Korea. NEPA was administered 1 h prior to chemotherapy initiation on day 1. The primary endpoint of the study was the complete response rate (no emesis, and no rescue medication) during the acute, delayed, and overall phases, which were assessed over a period of 120 h post-chemotherapy. The complete response rates for NEPA were 90.0% [95% CI 80.5, 95.9] for the acute phase, 85.7% [95% CI 75.3, 92.9] for the delayed phase, and 84.3% [95% CI 73.6, 91.9] for the overall phase, with no-emesis rates (acute: 97.1% [95% CI 97.1, 99.7], delayed: 95.7% [95% CI 88.0, 99.1], overall: 92.9% [95% CI 84.1, 97.6]). NEPA was well tolerated with no severe treatment-emergent adverse events. NEPA exhibited substantial efficacy in mitigating CINV in DLBCL patients undergoing R-CHOP chemotherapy, demonstrating high CR and no-emesis rates, and favorable safety profiles.

[Fire dragon cupping in prevention and treatment of chemotherapy-induced nausea and vomiting in breast cancer: a randomized controlled trial].

OBJECTIVE: To observe the clinical efficacy and safety of fire dragon cupping in prevention and treatment of chemotherapy-induced nausea and vomiting (CINV) in breast cancer. METHODS: Sixty breast cancer patients receiving medium-high emetogenic chemotherapy regimen were randomly divided into an observation group (30 cases, 3 cases dropped out) and a control group (30 cases, 3 cases dropped out). In both groups, 5 mg tropisetron hydrochloride was given intravenously on the day of chemotherapy and 1st to 3rd days after chemotherapy. In the observation group, fire dragon cupping on the abdomen was applied on 1st, 3rd and 5th days after chemotherapy. The incidence of nausea, vomiting, loss of appetite, abdominal pain, abdominal distension, the severity of nausea, vomiting on 1st to 6th days after chemotherapy, and the duration of nausea, vomiting, loss of appetite were observed in the two groups. The self-rating anxiety scale (SAS) score, general comfort questionnaire scale (GCQ) score before and after treatment and remedy antiemetic medication were observed in the two groups, and the safety was evaluated. RESULTS: On 2nd to 6th days after chemotherapy, the number of patients with nausea, loss of appetite and abdominal distension and nausea scores in the observation group were lower than those in the control group (P<0.05). On 1st to 3rd days after chemotherapy, the number of patients with vomiting and vomiting scores in the observation group were lower than those in the control group (P<0.05). The duration of nausea, vomiting and loss of appetite in the observation group were shorter than those in the control group (P<0.05). In the observation group, there was no significant difference in SAS and GCQ scores before and after treatment (P>0.05). After treatment, the GCQ score in the control group was decreased compared with that before treatment (P<0.05). After treatment, there was no significant difference in SAS and GCQ scores between the two groups (P>0.05). There was no significant difference in the number of patients using remedy medication between the two groups (P>0.05). No adverse reaction occurred during treatment in both groups. CONCLUSION: Fire dragon cupping can effectively reduce the incidence of nausea, vomiting, loss of appetite and the severity of nausea, vomiting related to chemotherapy in breast cancer, and improve patient comfort, and have good safety.

The prophylactic antiemetic therapies in management of differentiated thyroid cancer patients with radioactive iodine therapy: a single-center, non-randomized clinical trial.

Objective: The present study was to investigate three different single-drug regimens to show which was more effective to reduce radioactive iodine therapy (RAI) associated nausea and vomiting, and to compare the occurrence of long-term gastrointestinal diseases after RAI therapy. Method: We performed a single-center, non-randomized clinical trial among patients who underwent RAI therapy from March 2016 to July 2022. Enrolled patients were divided into four cohorts based on the date of the treatment. cohort 1, with no preventive antiemetics; cohort 2, received 20 mg of pantoprazole per day for 3 days; cohort 3, received a 10 mg metoclopramide tablet two times daily for 3 days; cohort 4, oral ondansetron, 8 mg, twice daily for 3 days. The primary endpoints were proportion of patients who experience vomiting episodes and nausea during the 7-day hospital period. Secondary end points included Functional Living Index Emesis (FLIE) quality-of life questionnaires and the occurrence of gastrointestinal diseases. Results: A total of 1755 patients were analyzed, comprised of 1299 (74.0%) women and 456 (26.0%) men, with a median age of 44 years (range 18-78 years). The characteristics of patient were similar within the four groups. 465 (26.4%) patients developed RAI-associated nausea, and 186 (14.4%) patients developed RAI-associated vomiting. The rate of nausea was significantly decreased in the patients who were taking ondansetron when compared with the other cohorts (P<0.05), while the rate of vomiting (≥6 episodes) was slightly lower. As secondary endpoint, FLIE measures ondansetron scored highly compared to other cohorts, from baseline (mean score of 110.53 ± 17.54) to day 7 (mean score of 105.56 ± 12.48). In addition, 48 (2.7%) patients were found to be with gastrointestinal diseases at the end of one year follow up. Multiple RAI therapy and higher dose of I-131 per body weight revealed a significantly independent risk factors of developing gastrointestinal disorders. Conclusions: In conclusion, the present study demonstrated that short-term ondansetron could be an effective prophylactic agent in controlling RAI-associated nausea and vomiting. Furthermore, the risk of developing gastrointestinal disorders was significantly higher for patients with multiple RAI therapy and higher dose of I-131 per body weight.

[China guidelines on prevention and treatment of nausea and vomiting caused by antitumor therapies (2023 edition)].

Epidemiologic data show that the incidence and mortality of cancer in China has been increasing, but the age-standardized mortality rate (ASMR) decreased. The descend trend in ASMR indicated that China has achieved remarkable results in the comprehensive prevention and control of cancer in recent decades through the risk factor control, cancer screening, early diagnosis and treatment, and standardization of diagnostic and therapeutic protocols. In recent years, new anti-tumor therapies and drugs have been developed, but nausea and vomiting are still common adverse event associated with many anti-tumor therapies and can negatively impact patients' quality of life and potentially limit the effectiveness of anti-tumor therapies. The experts from China Anti-Cancer Association Committee of Rehabilitation and Palliative Care, China Anti-Cancer Association Committee of Tumor Clinical Chemotherapy, China Anti-Cancer Association Committee of Neoplastic Supportive-care and Chinese Society of Clinical Oncology Committee of Supportive and Rehabilitative Care have integrated recent advances in the prevention and treatment of nausea and vomiting caused by anti-tumor therapy. Following the existing evidence in evidence-based medicine, referring to both domestic and international guidelines, and considering the clinical practice in China, the "Guidelines for China prevention and treatment of nausea and vomiting caused by antitumor therapies (2023 edition)," has been formulated, aiming to provide professional guidance for the prevention and treatment of chemotherapy-induced nausea and vomiting in anti-tumor therapy in China.

[Chemotherapy-induced nausea and vomiting in pediatric oncology patients: 2023 recommendations from the Supportive Care Committee of the French Society of Cancer in Children and Adolescents]. / Nausées et vomissements chimio-induits en oncohématologie pédiatrique : actualisation 2023 des recommandations du comité soins de support de la SFCE.

Chemotherapy-induced nausea and vomiting (CINV) are frequent and dreaded side effects in cancer treatments. CINV has a major impact on patient's condition and quality of life. Prophylaxis is tailored to patient's profile and the emetogenic level of their chemotherapy. The aim of this study is to update the recommendations for CINV prevention and management in pediatric onco-hematology for use in France, by adapting the guidelines of the Pediatric Oncology Group of Ontario (POGO). Clinical practice guideline adaptation is a recognized method for tailoring existing clinical practice guidelines to local context. A multidisciplinary French-speaking panel was formed to discuss about POGO guideline recommendations for the acute and delayed phases, breakthrough, refractory and anticipatory CINV and the evidence supporting them. Panel members were asked whether they wanted to adopt, modify or reject each of the POGO guideline recommendations. Panel members translated each recommendation and adapted recommendations for an implementation in France. Their acceptance required agreement at least 80 % of panel members. Algorithms and tables were created, listing all the recommendations and providing a better overview for decision-making process adapted to the patient's profile. These recommendations should be reviewed for implementation at French institutions caring for pediatric cancer patients and once implemented, the rates of adherence to recommendations and CINV control should be reported.
