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.

Effects of aromatherapy on nausea and vomiting in patients with cancer: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

and purpose: Aromatherapy offers a low-risk solution for effectively managing common nausea and vomiting in cancer patients. This systematic review and meta-analysis aimed to assess its impact on these symptoms to facilitate practical guidelines establishment.

METHODS

PubMed, Web of Science, Cochrane Library, MEDLINE, CINAHL, and Embase were searched for articles published until April 30, 2023. Inclusion criteria were randomized controlled trials (RCTs) on the effect of aromatherapy on nausea and vomiting in patients with cancer (age ≥18 years). The effect size was calculated using standardized mean differences (SMDs) with a random effects model. Subgroup analyses, meta-analysis of variance, and meta-regression were performed using the "meta" package in R version 4.0.2. Heterogeneity was assessed using I2 statistics. Sensitivity and publication bias analyses were performed; two reviewers independently assessed risk of bias using Cochrane's risk-of-bias tool 2.0.

RESULTS

Twenty-five RCTs across 10 articles revealed that aromatherapy reduced overall nausea and vomiting in patients with cancer with significant efficacy (SMD = -0.81, 95 % confidence interval [CI]: -1.11 to -0.52). Furthermore, aromatherapy reduced nausea (SMD = -0.85, 95 % CI: -1.23 to -0.46) and combined nausea and vomiting (SMD = -1.08, 95 % CI: -1.68 to -0.47), but not vomiting alone (SMD = -0.24, 95 % CI: -1.03 to 0.55). Inhalation and massage yielded positive results, especially in chemotherapy-induced cases; peppermint oil was particularly successful.

CONCLUSION

Our findings underscore aromatherapy's value in managing cancer treatment-associated nausea and vomiting. Conclusive evidence on aromatherapy-led nausea reduction is lacking due to limited RCTs; research is warranted for robust conclusions.

Trends in Gastroparesis Management: A United States Population-based Study From 2010 to 2020

BACKGROUND

There is little consensus on the medical management of gastroparesis, a disorder characterized by delayed gastric emptying with symptoms of early satiety, nausea, vomiting, and upper abdominal pain.

GOALS

We utilized population-level data to: (1) describe the prevalence of different pharmacological and nonpharmacological therapies in patients with gastroparesis; and (2) trend the prevalence of these therapies from 2010 to 2020.

STUDY

More than 59 million unique medical records across 26 US-based major health care systems were surveyed using the Explorys platform to identify a cohort of adults with gastroparesis who completed both a gastric emptying study and upper endoscopy or upper gastrointestinal tract imaging. Prevalence of antiemetic, prokinetic, neuromodulator prescriptions, and surgical therapies for gastroparesis were searched within this cohort and trended annually from 2010 to 2020.

RESULTS

Antiemetics (72% of patients), prokinetics (47%), and neuromodulators (75% of patients, 44% of patients without a concomitant psychiatric or diabetic peripheral neuropathy diagnosis) were all commonly used in the treatment of patients with gastroparesis. From 2010 to 2020, there was an increase in the prevalence of antiemetic and neuromodulator prescriptions (36.4% to 57.6%, P <0.001 and 47.0% to 66.9%, P <0.001, respectively), whereas the prevalence of prokinetics remained relatively constant (31.8% to 31.6%, P =0.52). Procedural and surgical treatments were used in 5% of gastroparesis patients.

CONCLUSIONS

Treatments for gastroparesis have changed over the last decade: antiemetic and neuromodulator use has increased whereas prokinetic use has remained constant. This practice pattern may reflect the growing number and availability of antiemetics and neuromodulators and the small number and known side effects of prokinetics.

Antiemetic Drugs Compatibility Evaluation with Paediatric Parenteral Nutrition Admixtures

Chemotherapy-induced nausea and vomiting are defined as the most common of side effects of treatment and, at the same time, are very difficult to accept for patients', frequently causing changes in the therapy regimen, significantly reducing its effectiveness. Thus, an antiemetic prophylactic is essential to the provision of such a therapy for the patient. Pharmacotherapy often includes various drugs, including antiemetics, with the administration of such drugs by injection through two separate catheters being the preferred method. However, the co-administration of drugs and parenteral nutrition admixtures (PNAs) requires the consideration of compatibility, stability and potential negative interactions. To meet the purposes of clinical pharmacy, a compatibility test of ondansetron, dexamethasone and hydrocortisone with paediatric PNAs was conducted. PNAs differ in the composition of amino acid source (Primene® or Aminoplasmal Paed® 10%) and the type of injectable lipid emulsion (Lipidem® 200 mg/mL, Clinoleic® 20%, SMOFlipid® 200 mg/mL, Intralipid® 20%). An in vitro evaluation was performed in a static way as a simulated co-administration through a Y-site. The drug PNA ratios were determined based on the extreme infusion rates contained in the characteristics of medicinal products. All calculations were performed for a hypothetical patient aged 7 years weighing 24 kg. As a result of this study, it can be concluded that all tested PNAs showed the required stability in the range of parameters such as pH, osmolality, turbidity, zeta potential, MDD and homogeneity. The co-administration of antiemetic drugs does not adversely affect lipid emulsion stability. This combination was consistently compatible during the evaluation period.

Effects of PC6 acupressure on acute and delayed nausea and vomiting induced by chemotherapy in patients with malignant neoplasm: a meta-analysis

OBJECTIVE

Evaluating the intervention effect of PC6 acupressure on chemotherapy-induced acute, delayed nausea, and vomiting in malignant tumor patients.

METHOD

Eleven databases had been retrieved from January 2010 through January 2022. The published meta-analysis literature was hand-searched, and the language was limited to English and Chinese. The protocol of this meta-analysis was registered with PROSPERO (registration number: CRD42022323693). Two reviewers independently selected relevant eligible articles, extracted data, and evaluated the risk of bias. Meta-analysis was statistically analyzed using software RevMan 5.3.

RESULT

Ten randomized controlled trials with 975 patients were included. Only two studies were assessed as high quality; eight studies were evaluated as moderate. Meta-analysis showed that compared with the control group, PC6 acupressure reduced the occurrence number of acute (SMD = -0.39,95CI (-0.73, -0.05) P = 0.02), delayed (SMD = -0.51, 95% CI (-0.96, -0.05) P = 0.03) nausea and acute (SMD = -0.42,95% CI (-0.79, -0.06) P = 0.02), delayed (SMD = -0.37, 95% CI (-0.77, 0.03) P = 0.07) vomiting; it reduced the severity of acute (SMD = -0.34, 95% CI (-0.57, -0.11) P = 0.004), delayed (SMD = -0.79, 95% CI (-1.33, -0.25) P = 0.004) nausea and acute (SMD = -0.51, 95% CI (-0.79, -0.23) P = 0.0004), delayed (SMD = -0.50, 95% CI (-0.84, -0.17) P = 0.003) vomiting, while it did not reduced the experience time on acute and delayed CINV.

CONCLUSION

The meta-analysis shows the effectiveness of PC6 acupressure in preventing and treating nausea and vomiting. Large, high-quality, well-designed randomized controlled trials are needed in the future to determine the efficacy of PC6 acupressure on chemotherapy-induced nausea and vomiting.

Modulatory effects of phytol on the antiemetic property of domperidone, possibly through the D2 receptor interaction pathway: in vivo and in silico studies

The current study is designed to evaluate the antiemetic effect of the diterpenoid phytol (PHY) using in vivo and in silico studies. For this, emesis was induced in 4-day-old chicks by the oral administration of copper sulfate (CuSO4.5H2O) at 50 mg/kg. To see the possible antiemetic mechanism of PHY, we used a number of reference drugs such as domperidone (80 mg/kg), ondansetron (24 mg/kg) and hyoscine (100 mg/kg) as positive controls, while the vehicle served as a negative control group. PHY was administered orally at the doses of 50 and 75 mg/kg. Both PHY and reference drugs were given alone or in combined groups to evaluate their synergistic or antagonistic effects on the chicks. Molecular docking of PHY and reference drugs was carried out against 5HT3, D2, D3, H1, NK1, and mAChRs (M1-M5) receptors for estimating binding affinity to the receptors. Drug-receptor interactions and active sites of the receptors were observed with the aid of different computational tools. The drug-likeness and pharmacokinetics of all the drugs were predicted through the SwissADME online database. The results suggest that PHY reduces the mean number of retches and increases latency dose-dependently in the birds. In the combination groups, PHY75 showed better antiemetic effects with domperidone and ondansetron. In addition, PHY exhibited the highest binding affinity with the D2 receptor (6CM4) (- 7.3 kcal/mol). In conclusion, PHY showed an antiemetic activity in chicks, possibly through the D2 receptor interaction pathway.

External Application of Traditional Chinese Medicine in the Prevention and Treatment of Nausea and Vomiting Caused by Chemotherapy of Non-Small-Cell Lung Cancer: A RCT Study

Objective. To investigate the external application of traditional Chinese medicine in the prevention and treatment of nausea and vomiting caused by chemotherapy of non-small-cell lung cancer. Methods. This is a prospective trial. A total of 114 patients with non-small-cell lung cancer who were hospitalized in our hospital from October 2020 to March 2022 were selected and randomly divided into the research group and the control group at the ratio of 1 : 1. The control group received chemotherapy + tropisetron 4 mg intravenous drip 30 minutes before chemotherapy./day × 3 days. The research group received chemotherapy + intravenous infusion of tropisetron 4 mg 30 minutes before chemotherapy, once a day for 3 days + external application of traditional Chinese medicine for 5 days. The therapeutic effects of the two groups of patients were compared. Results. After treatment, the serum creatinine, urea nitrogen, and endogenous creatinine in the research group were better than those in the control group (t = 15.943, 12.005, and 13.325; $P=0.001$ , 0.005, and 0.005). After treatment, ALT and TBIL in the research group were superior to those in the control group (t = 11.583, 10.012, and 9.426; $P=0.001$ , 0.002, and 0.001). After treatment, the physiological status, social/family status, emotional status, and family status of the research group were significantly better than those in the control group (t = 16.274, 5.379, 5.142, and 8.153; $P=0.005$ , 0.000, 0.002, and 0.001). After treatment, the ECOG score and KPS score (82.46 ± 4.61) of the research group were significantly different from those of the control group (t = 11.913 and 9.357; $P=0.035$ and 0.001). The effective rate (χ2 = 11.724; $P=0.000$ ) of the research group was higher but the incidence of adverse reaction (χ2 = 4.294; $P=0.001$ ) was lower than that of the control group. Conclusion. External application of traditional Chinese medicine can significantly reduce nausea and vomiting caused by chemotherapy of non-small-cell lung cancer and can improve the patient’s body and quality of life, which is worthy of clinical research and promotion.

Chinese Medicine Syndrome Differentiation for Early Breast Cancer: A Multicenter Prospective Clinical Study

Background

Chinese medicine (CM) syndrome differentiation is one of the fundamental principles that guide the practice of Chinese herbal medicine (CHM). CHM has been widely used among breast cancer patients. Contemporary literature varies in syndrome diagnosis, and there is a need to standardize syndrome differentiation according to the different stages of breast cancer treatment. This multicenter clinical study aims to identify the CM syndromes and the clinical signs and symptoms in women with early breast cancer.

Methods

Participants who met the inclusion and exclusion criteria were interviewed during the five treatment stages: preoperative, postoperative, chemotherapy, radiation therapy, and endocrine therapy. Patient demographic data and CM syndrome (as recorded by the treating CM clinicians in medical records) were gathered. Signs and symptoms were analyzed using descriptive statistics to derive the standardized CM syndromes using hierarchical cluster analysis.

Results

The analysis included 964 interviews with 620 participants enrolled between April 29, 2020 and May 30, 2021 from eight participating hospitals in China. The two most frequent syndromes recorded in medical records were dual deficiency of qi and blood, and dual deficiency of qi and yin during all but the preoperative stage. The symptoms of lassitude, lack of strength, and insomnia were common in all but the preoperative stage. Cluster analysis identified two clusters in the preoperative stage that most closely resembled the syndrome diagnoses of liver stagnation with congealing phlegm, and dual deficiency of the liver and kidney. Two clusters—dual deficiency of qi and blood, and dual deficiency of qi and yin—were common to multiple treatment stages. The syndrome cluster of spleen and stomach disharmony existed in both the postoperative and chemotherapy stages. Cluster analysis of the radiation therapy stage identified the unique syndrome of yin deficiency with fire toxin, while the endocrine therapy included the syndromes of liver depression and kidney deficiency.

Conclusions

This multicenter clinical study showed consistency between results from cluster analysis and the most common syndromes recorded in the medical records. Findings from this clinical study will be further validated in a Delphi study to standardize CM syndromes for various stages of breast cancer treatment.

Olanzapine 5 mg for Nausea and Vomiting in Patients with Nasopharyngeal Carcinoma Receiving Cisplatin-Based Concurrent Chemoradiotherapy

Purpose

To explore the efficacy and safety of adding olanzapine (5 mg or 10 mg) to 5-hydroxytryptamine type 3 receptor antagonists (5-HT₃ RA), neurokinin-1 receptor antagonists (NK1 RA), and dexamethasone for nausea and vomiting in patients with nasopharyngeal carcinoma (NPC) receiving cisplatin-based concurrent chemoradiotherapy.

Methods

Patients receiving olanzapine 5 mg or 10 mg combined with 5-HT₃ RA, NK1 RA, and dexamethasone during the cisplatin-based concurrent chemoradiotherapy were included. The primary endpoint was the complete response (CR) (no vomiting) rate, and the secondary endpoint was the incidence of no nausea.

Results

A total of 150 chemotherapy cycles were administrated for 88 patients (75 in the olanzapine 5 mg group and 75 in the olanzapine 10 mg group). The proportions of CR in the olanzapine 5 mg group were comparable to those in the olanzapine 10 mg group in acute (93.3% vs. 94.7%, P = 0.731), delayed (76% vs. 78.7%, P = 0.697), and overall phase (73.3% vs. 77.3%, P = 0.570). Moreover, no nausea rates were also comparable between the two groups in acute (76% vs. 78.7%, P = 0.697), delayed (54.7% vs. 60%, P = 0.509), and overall period (50.7% vs. 57.3%, P = 0.111). Regarding the adverse effects, the incidence of somnolence in the 10 mg group (58.6%) was significantly higher than that in the 5 mg group (41.3%) (P = 0.034), while constipation (20.0% vs. 24.0%, P = 0.554) and hiccups (9.3% vs. 10.6%, P = 0.785) rates were comparable in two groups.

Conclusions

Patients receiving olanzapine plus standard antiemetic therapy has excellent antiemetic effect in NPC patients receiving cisplatin-based concurrent chemoradiotherapy, and patients with olanzapine 5 mg have a similar antiemetic effect and lower adverse effects compared with those with olanzapine 10 mg.

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

The significant physical and emotional effects of chemotherapy-induced nausea and vomiting (CINV) are experienced by cancer patients. Severe symptoms decrease the patient's quality of life and potentially deters further treatment. The five main forms of CINV (i.e., acute, delayed, anticipatory, breakthrough, and refractory) require different treatment regimens, which often include 5-HT3 receptor antagonists, NK1 receptor antagonists, and corticosteroids. Despite a significant amount of research and development of antiemetic agents, management of CINV remains a great challenge with many needs waiting to be adequately addressed, such as controlling non-acute CINV, developing appropriate CINV treatment protocols for multiple-day chemotherapy patients, and providing options for those prone to CINV despite treatment. Further research is required to optimize CINV management for these patients.

"Emotional Chemobrain": A new concept for chemotherapy adverse drug effect?

"Emotional chemobrain" is a new paradigm that relates the occurrence of alterations in the psychological wellbeing of patients to the adverse drug effects of chemotherapy on the neurobiological level. The concept of "emotional chemobrain" is the analogue concept of the classical concept of "chemobrain" but that concerns emotional disturbances related to chemotherapy. Disgust is a negative emotion that might accompany any stressful life event such as having cancer. Increased disgust may lead to the development of mental disorders such as mood and anxiety disorders. Patients with cancer may develop negative emotions such as self-disgust because of their affected autonomy and life style on the one hand and because of chemotherapy's effect on their brain on the other. Self-disgust might be considered as a factor contributing to psychological distress exacerbation in this category of physically ill individuals. In addition to lifestyle modifications and body changes, self-disgust might be exacerbated by chemotherapy in the same way other negative emotions might be exacerbated by this kind of treatment. It might be speculated that the emotional side effects of chemotherapy concern activation modifications in brain regions relevant to emotional elaboration and regulation such as the insular lobe and the amygdala. "Emotional chemobrain" should be considered whenever neuropsychiatric adverse effects of chemotherapy are manifested in patients with cancer. Future studies might be interested in studying the effect of chemotherapy on brain regions that can affect regulation of emotions such as self-disgust.

Marijuana, Ondansetron, and Promethazine Are Perceived as Most Effective Treatments for Gastrointestinal Nausea

BACKGROUND

Many anti-nausea treatments are available for chronic gastrointestinal syndromes, but data on efficacy and comparative effectiveness are sparse.

AIMS

To conduct a sectional survey study of patients with chronic nausea to assess comparative effectiveness of commonly used anti-nausea treatments.

METHODS

Outpatients at a single center presenting for gastroenterology evaluation were asked to rate anti-nausea efficacy on a scale of 0 (no efficacy) to 5 (very effective) of 29 commonly used anti-nausea treatments and provide other information about their symptoms. Additional information was collected from the patients' chart. The primary outcome was to determine which treatments were better or worse than average using a t test. The secondary outcome was to assess differential response by individual patient characteristics using multiple linear regression.

RESULTS

One hundred and fifty-three patients completed the survey. The mean efficacy score of all anti-nausea treatments evaluated was 1.73. After adjustment, three treatments had scores statically higher than the mean, including marijuana (2.75, p < 0.0001), ondansetron (2.64, p < 0.0001), and promethazine (2.46, p < 0.0001). Several treatments, including many neuromodulators, complementary and alternative treatments, erythromycin, and diphenhydramine had scores statistically below average. Patients with more severe nausea responded better to marijuana (p = 0.036) and diphenhydramine (p < 0.001) and less so to metoclopramide (p = 0.020). There was otherwise no significant differential response by age, gender, nausea localization, underlying gastrointestinal cause of nausea, and GCSI.

CONCLUSIONS

When treating nausea in patients with chronic gastrointestinal syndromes, clinicians may consider trying higher performing treatments first, and forgoing lower performing treatments. Further prospective research is needed, particularly with respect to highly effective treatments.

The effect of ginger (Zingiber officinale) on chemotherapy-induced nausea and vomiting in breast cancer patients: A systematic literature review of randomized controlled trials

Breast cancer is the most commonly diagnosed cancer and is the leading cause of mortality due to all types of cancers among the female population worldwide. Results of clinical trials investigating the effect of ginger on chemotherapy-induced nausea and vomiting (CINV) in breast cancer patients are inconsistent. This study was aimed at obtaining a comprehensive overview of the current evidence regarding the effectiveness of ginger as an antiemetic modality for controlling CINV in breast cancer patients. All published randomized controlled trials in English were systematically searched on Google Scholar, PubMed, Scopus, and Cochrane search databases up to June 2018. The outcome variable of interest was severity and the frequency of nausea and vomiting in patients. A total of 50 studies were found through search databases. After excluding duplicates, the 42 remaining studies were screened, and finally, nine trials were included, which were published between 2012 and 2017. Two studies have examined the effect of ginger on the frequency of nausea, five studies on the frequency of vomiting, seven studies on the severity of nausea, and three studies on severity of vomiting. A study evaluated the effectiveness of ginger in improving dietary intake in CINV. Our investigation suggests that ginger may reduce nausea in the acute phase of chemotherapy in patients with breast cancer. The effect of ginger on nausea and vomiting in other conditions requires more high-quality clinical trials.

Metabolites of Vinca Alkaloid Vinblastine: Tubulin Binding and Activation of Nausea-Associated Receptors

Vinblastine (VLB) is an antimitotic drug that binds to the vinca site of tubulin. The molecule possesses a high molecular weight and a complex chemical structure with many possibilities of metabolization. Despite advances in drug discovery research in reducing drug toxicity, the cause and mechanism of VLB-induced adverse drug reactions (ADRs) remains poorly understood. VLB is metabolized to at least 35 known metabolites, which have been identified and collected in this present work. This study also explores how VLB metabolites affect nausea-associated receptors such as muscarinic, dopaminergic, and histaminic. The metabolites have stronger binding interactions than acetylcholine (ACh) for muscarinic M₁, M₄, and M₅ receptors and demonstrate similar binding profiles to that of the natural substrate, ACh. The affinities of VLB metabolites to dopaminergic and histaminic receptors, their absorption, distribution, metabolism, excretion, toxicity properties, and the superiority of VLB to ACh for binding to M₅R, indicate their potential to trigger activation of nausea-associated receptors during chemotherapy with VLB. It has been shown that metabolite 20-hydroxy-VLB (metabolite 10) demonstrates a stronger binding affinity to the vinca site of tubulin than VLB; however, they have similar modes of action. VLB and metabolite 10 have similar gastric solubility (FaSSGF), intestinal solubility (FeSSIF), and log P values. Metabolite 10 has a more acceptable pharmacokinetic profile than VLB, a better gastric and intestinal solubility. Furthermore, metabolite 10 was found to be less bound to plasma proteins than VLB. These are desired and essential features for effective drug bioavailability. Metabolite 10 is not a substrate of CYP2D6 and thus is less likely to cause drug-drug interactions and ADRs compared to its parent drug. The hydroxyl group added upon metabolism of VLB suggests that it can also be a reasonable starting compound for designing the next generation of antimitotic drugs to overcome P-glycoprotein-mediated multidrug resistance, which is often observed with vinca alkaloids.

Effect of electrical stimulation for chemotherapy-induced nausea and vomiting in patients with liver cancer

BACKGROUND

This study will be proposed for assessing the effects of electrical stimulation (ES) for chemotherapy-induced nausea and vomiting (CINV) in patients with liver cancer (LC).

METHODS

We will identify the relevant literatures of ES for CINV in patients with LC from following databases: Cochrane Library, PUBMED, EMBASE, Web of Science, the Cumulative Index to Nursing and Allied Health Literature, the Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure from inception to the date of literature searched without any language restrictions. Randomized controlled trials and case-control studies on assessing of effects and safety of ES for CINV in patients with LC will be included. Methodological quality for all included studies will be assessed by using Cochrane risk of bias tool. RevMan 5.3 software (Cochrane Community, London, UK) will be used to analyze the data.

RESULTS

This study will summarize current evidence for ES on CINV in patients with LC. Primary outcome includes symptoms severity. Secondary outcomes consist of appetite, performance status, health-related quality of life, and adverse events.

CONCLUSION

The results of this study will provide latest evidence to judge the effects and safety for ES on CINV in patients with LC.

Nurse-led interventions on quality of life for patients with cancer: A meta-analysis

BACKGROUND

To compare the quality of life outcome between nurse-led and non-nurse-led interventions for patients with cancer using a meta-analysis.

METHODS

A systematic literature review was performed by searching randomized controlled trials about nurse-led interventions in PubMed, EMBASE, and Cochrane Library databases until June 2017. Pooled summary estimates for quality of life outcome was calculated as standardized mean difference (SMD) either on a fixed- or random-effect model via Stata 13.0 software.

RESULTS

Seven literatures involving 1110 patients (554 in the nurse-led group and 556 in the control group) were included. Pooled analysis showed there were no differences in the global quality of life, cognitive, emotional, role, social and physical functions, appetite loss, diarrhea, and dyspnea scales of Quality of Life Questionnaire C30 version 3.0 core (QLQ-C30) questionnaires between the nurse-led and control groups. However, the nurse-led management program significantly decreased the occurrence of constipation (SMD = -0.36, 95% CI = -0.71 to -0.00; P = .001) and insomnia (SMD = -0.33, 95% CI = -0.99 to 0.32; P = .011) and reduced the financial difficulty (SMD = -0.34, 95% CI = -0.65 to -0.03; P = .033) for patients with cancer.

CONCLUSION

The nurse-led disease management strategy seemed to be effective to improve constipation, insomnia, and financial impacts for patients with cancer in quality of life assessment.

Impact of Cancer Awareness Drive on Generating Understanding and Improving Screening Practices for Breast Cancer: a Study on College Teachers in India

Background:

Breast cancer is the most common cancer among women in India and most present at advanced stage. Although early detection is the only way to reduce morbidity and mortality, people have a very low awareness about breast cancer signs and symptoms and screening practices. The purpose of this study was to assess the level of awareness and impact of awareness programs in adoption of safe practices in prevention and early detection.

Methods:

This assessment was part of a pink chain campaign on cancer awareness. During events from 2011 to 2015 at various women colleges in different parts in India, a pre-test of knowledge related to breast cancer was followed by an awareness program. Post-tests using the same questionnaire were conducted at the end of the interactive sessions, at 6 months and after1 year.

Results:

A total of 872 out of 985 teachers participated in the study (overall response rate of 88.5 %). Mean age of the study population was 41.6 years (range 28-59 yrs). There was a significant increase in level of knowledge regarding breast cancer at 6 months and this was sustained at 1 year. Adoption of breast self-examination (BSE) was significantly more frequent in comparison to CBE and mammography. Magazines and newspapers were sources for knowledge regarding screening tests for breast cancer for more than 60% of teachers. Regarding post-awareness at 6 months and 1 year, there was a significant change in alcohol and smoking habits. Major reasons came out to be ignorance (83%) at the start of the campaign which was changed to lack of time (37.7%), lethargic attitude (32.2 %) and lack of time (31.5 %) at 6 months and same at 1 year also.

Conclusions:

With our awareness program there was a significant increase in level of knowledge regarding breast cancer at 6 months and this was sustained at 1 year. Adoption of BSE was significantly greater in comparison to CBE, mammography. To inculcate safe lifestyle practices in people, awareness programmes such as pink chain campaigns should be conducted more widely and frequently.

Granisetron Extended-Release Injection: A Review in Chemotherapy-Induced Nausea and Vomiting

An extended-release (ER) subcutaneously injectable formulation of the first-generation 5-HT₃ receptor antagonist granisetron is now available in the USA (Sustol^®), where it is indicated for the prevention of acute and delayed chemotherapy-induced nausea and vomiting (CINV) following moderately emetogenic chemotherapy (MEC) or anthracycline and cyclophosphamide combination chemotherapy regimens in adults. Granisetron ER is administered as a single subcutaneous injection and uses an erosion-controlled drug-delivery system to allow prolonged granisetron release. Primary endpoint data from phase III studies after an initial cycle of chemotherapy indicate that, when used as part of an antiemetic regimen, granisetron ER injection is more effective than intravenous ondansetron in preventing delayed CINV following highly emetogenic chemotherapy (HEC); is noninferior to intravenous palonosetron in preventing both acute CINV following MEC or HEC and delayed CINV following MEC; and is similar, but not superior, to palonosetron in preventing delayed CINV following HEC. The benefits of granisetron ER were seen in various patient subgroups, including those receiving anthracycline plus cyclophosphamide-based HEC, and (in an extension of one of the studies) over multiple MEC or HEC cycles. Granisetron ER injection is generally well tolerated, with an adverse event profile similar to that of ondansetron or palonosetron. Thus, granisetron ER injection expands the options for preventing both acute and delayed CINV in adults with cancer receiving MEC or anthracycline plus cyclophosphamide-based HEC.
