ASCO Rapid Recommendations Updates highlight revisions to select ASCO guideline recommendations as a response to the emergence of new and practice-changing data. The rapid updates are supported by an evidence review and follow the guideline development processes outlined in the ASCO Guideline Methodology Manual . The goal of these articles is to disseminate updated recommendations, in a timely manner, to better inform health practitioners and the public on the best available cancer care options. See the Appendix for disclaimers and other important information ( Appendix 1 and Appendix 2 , online only).

Abstract Purpose A protocol was developed to evaluate the value of an NK-1 receptor antagonist for preventing nausea and vomiting resulting from highly emetogenic chemotherapy when an olanzapine-based antiemetogenic regimen was used. Materials and Methods A221602, a prospective double-blind, placebo-controlled clinical trial, was developed to compare 2 ­olanzapine-containing antiemetic regimens, one with an NK-1 receptor antagonist (aprepitant or fosaprepitant) and one without. Trial patients had a malignant disease for which they received intravenous highly emetogenic chemotherapy (single day cisplatin ≥ 70 mg/m2 or doxorubicin plus cyclophosphamide on 1 day). Patients on both arms received commonly administered doses of a 5-HT3 receptor antagonist, dexamethasone, and olanzapine. Additionally, patients were randomized to receive an NK-1 receptor antagonist (fosaprepitant 150 mg IV or aprepitant 130 mg IV) or a corresponding placebo. The primary objective was to compare the proportion of patients with no nausea for 5 days following chemotherapy between the 2 study arms. This trial was designed to test for the noninferiority of deleting the NK-1 receptor antagonist, with noninferiority defined as a decrease in freedom from nausea by less than 10%. Results A total of 690 patients were entered on this trial, 50% on each arm. The proportion of patients without nausea for the complete 5-day study period was 7.4% lower (upper limit of the one-sided 95% confidence interval was 13.5%) in the arm without an NK-1 receptor antagonist compared with the arm with an NK-1 receptor antagonist. Conclusion This trial did not provide sufficient evidence to support that deletion of the NK-1 receptor antagonist was as good as keeping it, as a part of a 4-drug antiemetic regimen for highly emetogenic chemotherapy (ClinicalTrials.gov Identifier: NCT03578081).

12114 Background: A retrospective study suggested a potential benefit from rose geranium in sesame oil nasal spray for alleviating nasal vestibulitis symptoms in patients (pts) undergoing chemotherapy. Methods: Pts undergoing active chemotherapy who reported moderate or worse nasal symptoms were randomized 1:1 to receive a rose geranium in sesame oil nasal spray (RG) or an isotonic saline nasal spray (IS), administered twice daily for two weeks. Consenting pts completed nasal symptom questionnaires at baseline and then weekly while on treatment. The number and percentage of pts experiencing improvements in their nasal symptoms 2 weeks after initiating the nasal spray, defined as symptoms moderately (2) or very much (3) better on a 7-point global impression of change score (ranging from scores of -3: very much worse, to 3: very much better), was estimated within and then between each randomized arm, using Fisher’s exact test (5% significance level). The estimated odds ratio was determined (95% confidence interval). After 2 weeks, pts initially randomized to IS were allowed to cross-over to RG and completed weekly surveys. Results: 106 pts consented to this study; 43 pts in the RG arm and 41 in the IS arm were evaluable for the primary endpoint. Pts had a mean age of 57.8 (SD 13.9). Demographic characteristics and baseline nasal symptoms were similar between arms. The most prominent baseline nasal symptoms were dryness (36%) and bleeding (35%). Of the 43 evaluable pts who received RG, 67.4% reported improved nasal symptoms, compared with 36.6% of the 41 pts who received IS (p=0.009; Table). On the global impression of change score, pts who received RG had a mean score of 1.93 (SD 1.16), compared to a mean score of 0.98 (SD 1.41) among pts who received IS. Adjusting for potential confounding factors, pts who received RG had a 4.56 odds of responding to the nasal spray, compared with those who received IS (p=0.005). There were no significant differences between pt responses based upon type of nasal symptoms, age, allergies, or gender. Adverse events were sparse and did not differ between arms. 34 pts crossed over to RG after week 2. Among the 29 pts who completed final surveys, 37% reported a response on IS, 79% reported a response on RG. Conclusions: Rose geranium in sesame oil nasal spray significantly improves nasal vestibulitis symptoms among patients undergoing chemotherapy. Clinical trial information: NCT04620369 .

e19517 Background: Anthracycline-induced cardiotoxicity (AIC) is a well-known phenomenon, but event rates and predictors may not be as robust as commonly perceived. We performed a systematic review and meta-analysis to elucidate AIC definitions, incidence rates and predictors. Methods: 5323 reports were identified via searching Medline, Embase, and Scopus. Inclusion criteria for full text review included minimum of 100 lymphoma patients receiving ACs; median/mean follow up of at least 12 months; and specified evaluation of left ventricular ejection fraction. We investigated the definition, reported incidence, and predictors of AIC including subclinical AIC as detected by decrease in left ventricular systolic dysfunction. Meta-analysis was performed with Meta-analyst software with random effects model. Results: A total of 19 studies were included in the analysis. The overall incidence of AIC in 13926 patients was 13.8% (95% CI 4.8-22.8, I2 99.6% p < 0.001) at a mean/median follow-up ranging from 1 to 8 years. Subclinical AIC was seen in 8.2% of 5464 patients (95% CI 6.4 to 10%, I2 78.9%, p < 0.001) at a mean/median follow-up ranging from 1 to 20 years. Subclinical AIC is defined in most studies as asymptomatic decrease in LVEF by 10-15% from baseline of 50-55%. Older age, increasing AC dose or number of cycles, GLS (global longitudinal strain), and prior comorbidities such as CAD, HTN, DM and dyslipidemia were found to predict AIC. However, Heterogeneity was seen in definition of AIC, risk factor assessment and follow-up protocol, which limited the extent of correlative analyses for cardiotoxicity predictors. Conclusions: The overall incidence of clinical HF and subclinical AIC among lymphoma patients was 13.8% and 8.2% respectively. Older age, increasing AC dose or number of cycles, GLS, and prior comorbidities such as CAD, HTN, DM and dyslipidemia were found to predict AIC.

AbstractIntroductionNasal symptoms are frequently reported by patients undergoing chemotherapy.MethodsEligible patients planning to receive paclitaxel, docetaxel, nab‐paclitaxel, bevacizumab without a concomitant taxane, or “other” (non‐taxane, non‐bevacizumab) chemotherapy regimens were invited to participate in this prospective study. Patients reported nasal symptoms prior to each dose of chemotherapy.ResultsThe percentage of patients (95% CI) who reported nasal symptoms was the same for patients who received bevacizumab or nab‐paclitaxel, 82.6% (61.2%, 95.1%). There were no significant differences among the proportions of patients experiencing nasal symptoms within the paclitaxel, nab‐paclitaxel, and bevacizumab cohorts. Patients in the nab‐paclitaxel cohort were more likely to experience symptoms than those in the non‐taxane non‐bevacizumab cohort or docetaxel cohort (p = 0.001, p = 0.001). Patients in the bevacizumab cohort were more likely to experience nasal symptoms than those in the non‐taxane non‐bevacizumab cohort (p = 0.03).ConclusionNasal vestibulitis symptoms are common in patients receiving chemotherapy, especially those receiving paclitaxel, docetaxel, and bevacizumab. Further investigations into treatments of this symptom complex are warranted.

PURPOSE: For the past 5 years, most major antiemesis guidelines have included olanzapine-containing regimens among the recommended options for prophylaxis with highly emetogenic chemotherapy (HEC). We analyzed the uptake of olanzapine in clinical practice and the changing composition of multidrug antiemetic regimens. METHODS: A retrospective analysis was performed using an OptumLabs deidentified database of medical and pharmacy claims, which was filtered for patients starting HEC in the interval of 2006 to Q2 of 2021. Descriptive statistics were used to analyze patient characteristics and year-by-year antiemetic prescribing patterns, coinciding with cycles 1 and 2 of chemotherapy. RESULTS: A total of 63,154 distinct patients were included. The median age was 58 years (range, 18-88). Breast (45.2%) and hematologic (20.8%) cancers were the most common diagnoses. In 2016, olanzapine was prescribed to 1.4% of patients with cycle 1 of HEC. Prescriptions increased modestly each year, and by 2021, 13.9% of patients received olanzapine with their first cycle of chemotherapy. An additional 5.7% of patients received olanzapine for breakthrough symptoms or enhanced prophylaxis during cycle 2. In 2021, more than three-quarters of patients were prescribed antiemetics in a guideline-concordant manner, with an olanzapine-containing quadruplet (12.2%), an NK1-receptor antagonist triplet (64.5%), or an olanzapine triplet (suppressed for small sample size). CONCLUSION: Despite inclusion in major antiemesis guidelines, there has been relatively slow uptake of olanzapine for prophylaxis with HEC. This finding highlights the challenges of disseminating information and keeping prescribing systems updated with the newest evidence in supportive oncology.

232 Background: Olanzapine has an important role in preventing and treating nausea and vomiting from highly emetogenic chemotherapy (HEC). This drug, for the last 5 years, has been a component of most major antiemesis guidelines. The aim of the current study was to assess how often olanzapine has been prescribed for patients receiving HEC. Methods: A retrospective analysis was performed using an OptumLabs de-identified clinical database of medical and pharmacy claims. The database was filtered for patients starting HEC in the interval of 2006 to Q2 of 2021. Descriptive statistics were used to analyze patient characteristics and year-by-year antiemetic prescribing patterns, coinciding with cycles 1 and 2 of chemotherapy. Results: A total of 63,154 distinct patients were included. The median age was 58 years (range, 18-88). Over a quarter of the patients identified as Black, Hispanic, Asian, or other. Breast (45.2%) and hematologic (20.8%) cancers were the most common diagnoses. In 2016, olanzapine was prescribed to only 1.4% of patients with cycle 1 of HEC. Prescriptions increased modestly each year, and by 2021, 13.9% of patients received olanzapine with their first cycle of chemotherapy. An additional 5.7% of patients received olanzapine for breakthrough symptoms or enhanced prophylaxis during cycle 2. In 2021, over three-quarters of patients were prescribed antiemetics in a guideline concordant manner, with either an olanzapine-containing quadruplet (12.2%), an NK1 receptor antagonist triplet (64.5%), or an olanzapine triplet (exact number suppressed due to small sample size). Conclusions: The rate of olanzapine prescribing is less than might be expected following its inclusion in major antiemesis guidelines. This finding highlights the challenges of disseminating information and keeping prescribing systems updated with the newest evidence in supportive oncology.

PURPOSE The aim of this joint guideline is to provide evidence-based recommendations to practicing physicians and other health care providers on integrative approaches to managing pain in patients with cancer. METHODS The Society for Integrative Oncology and ASCO convened an expert panel of integrative oncology, medical oncology, radiation oncology, surgical oncology, palliative oncology, social sciences, mind-body medicine, nursing, and patient advocacy representatives. The literature search included systematic reviews, meta-analyses, and randomized controlled trials published from 1990 through 2021. Outcomes of interest included pain intensity, symptom relief, and adverse events. Expert panel members used this evidence and informal consensus to develop evidence-based guideline recommendations. RESULTS The literature search identified 227 relevant studies to inform the evidence base for this guideline. RECOMMENDATIONS Among adult patients, acupuncture should be recommended for aromatase inhibitor–related joint pain. Acupuncture or reflexology or acupressure may be recommended for general cancer pain or musculoskeletal pain. Hypnosis may be recommended to patients who experience procedural pain. Massage may be recommended to patients experiencing pain during palliative or hospice care. These recommendations are based on an intermediate level of evidence, benefit outweighing risk, and with moderate strength of recommendation. The quality of evidence for other mind-body interventions or natural products for pain is either low or inconclusive. There is insufficient or inconclusive evidence to make recommendations for pediatric patients. More research is needed to better characterize the role of integrative medicine interventions in the care of patients with cancer.

Abstract Physical activity (PA) is associated with improvement in breast cancer treatment-related symptoms and survival, yet most breast cancer survivors do not meet national PA guidelines. This study aimed to identify characteristics of participants that were associated with an increased likelihood of meeting PA guidelines. Adults with breast cancer seen at Mayo Clinic (Rochester, MN) were surveyed regarding their PA participation, and those who self-reported at least 150 minutes of moderate and/or strenuous aerobic PA weekly on average were considered to be “meeting guidelines”. Three thousand participants returned PA data. Younger age, completion of the survey 7-12 years after diagnosis, absence of recurrence, no bilateral mastectomy, absence of metastatic disease, and lower BMI at the time of survey completion were associated with PA participation (P &lt; .05 in univariate and multivariate analyses). Findings were similar when a threshold of 90 minutes was applied. These results may inform the development of targeted PA-facilitating interventions.
