ABSTRACT

OBJECTIVE:

To estimate the incidence and to evaluate risk factors for antineoplastic nausea and vomiting with high and moderate emetogenic chemotherapy in adult patients in the first treatment cycle.

METHODS:

Prospective cohort study with follow-up of 269 adults during the first cycle of antineoplastic chemotherapy. The incidence of nausea and vomiting was evaluated in the acute phase (0–24 hours), in the late phase (24 hours–5th day) and in the total phase (0–5th day).

RESULTS:

In total, 152 patients underwent high emetogenic chemotherapy and 117 moderate emetogenic chemotherapy. The relative frequency of nausea was higher when compared with vomiting in the acute phase (p < 0.001) and in the late phase (p < 0.001). The risk factors identified were: age group ≤ 49 years (odds ratio = 0.47; 95%CI 0.23–0.95) and 50–64 years (odds ratio = 0.45; 95%CI 0.23–0.87), tobacco use (odds ratio = 0.35; 95%CI 0.14–0.88), and high emetogenic chemotherapy (odds ratio 0.55; 95%CI 0.31–0.95).

CONCLUSION:

The incidence of nausea was higher than that of vomiting, and adverse effects were more frequent in the late phase. The results suggest the risk factors for chemotherapy-induced nausea and vomiting are tobacco, age (young adults), and high emetogenic chemotherapy.

INTRODUCTION

Cancer is a public health issue and its prevention and control are challenges for this century. However, antineoplastic drugs have side effects that worsen the quality of life, in addition to being expensive and possibly leading to treatment discontinuation. Chemotherapy-induced nausea and vomiting (CINV) are the most frequent gastrointestinal adverse effects, despite advances in prophylactic therapies11. Chopra D, Rehan HS, Sharma V, Mishra R. Chemotherapy-induced adverse drug reactions in oncology patients: a prospective observational survey. Indian J Med Paediatr Oncol. 2016;37(1):42-6. https://doi.org/10.4103/0971-5851.177015
https://doi.org/10.4103/0971-5851.177015...
. Nausea is described as a subjective, painless sensation that precedes vomiting, and vomiting is described as the expulsion of gastric contents through the mouth22. Singh P, Yoon SS, Kuo B. Nausea: a review of pathophysiology and therapeutics. Therap Adv Gastroenterol. 2016;9(1):98-112. https://doi.org/10.1177/1756283X15618131

.

CINV episodes can be classified according to the phase of their occurrence. The first 24 hours after the start of chemotherapy infusion are called the “acute phase.” The period from 24 hours to 5 days is called “late phase44. Schwartzberg LS, Rugo HS, Aapro MS.. New and emerging therapeutic options for the management of chemotherapy-induced nausea and vomiting. Clin Adv Hematol Oncol. 2015;13(3 Suppl 3):3-14..”

Among the risk factors for CINV, chemotherapy agents and combinations of agents are categorized as minimalEC), low (LEC), moderate (MEC), or high (HEC) emetogenic chemotherapy55. Roila F, Herrstedt J, Aapro M, Gralla RJ, Einhorn LH, Ballatori E, et al.

https://doi.org/10.1093/annonc/mdq194...
. Other risk factors are: being a woman, having already received chemotherapy in previous treatments, being aged under 50 years, use of medicines, impaired emotional state, brain metastases, tobacco use and non-alcohol consumption66. Haiderali A, Menditto L, Good M, Teitelbaum A, Wegner J. Impact on daily functioning and indirect/direct costs associated with chemotherapy-induced nausea and vomiting (CINV) in a U.S. population.

.

The risk of CINV for patients undergoing chemotherapy with HEC and MEC is estimated at 90% and 30–90%, respectively. In Brazil, there is no antiemetic protocol established. However, the Consenso Brasileiro de Náuseas e Vômitos em Cuidados Paliativos (Brazilian Consensus on Nausea and Vomiting in Palliative Care) refers to the protocol of the Multinational Association for Support in Cancer Care (MASCC) and the European Society of Medical Oncology (ESMO)77. Associação Brasileira de Cuidados Paliativos. Consenso brasileiro de náuseas e vômitos em cuidados paliativos. Rev Bras Cuid Paliat. 2011 [cited 2015 Jan 10];3(3 Supl 2):1-26.

. CINV worsens the quality of life of cancer patients, causing lack of appetite, weight loss, decreased social life and even more serious clinical consequences, such as dehydration and cachexia88.

Considering the relevance of these adverse effects, this study aims was to estimate the incidence and evaluate the risk factors for antineoplastic chemotherapy-induced nausea and vomiting with high and moderate emetogenic chemotherapy in adult patients in the first treatment cycle.

METHODS

Prospective cohort study with patients who started chemotherapy between June and December 2015 in three reference oncology hospitals in the city of Belo Horizonte (MG), whose estimated population is 2,238,526 inhabitants1111. Caiaffa WT, Almeida MCM, Oliveira CDL, Friche AAL, Matos SG, Dias MAS, et al. The urban environment from the health perspective: the case of Belo Horizonte, Minas Gerais, Brazil. Cad Saude Publica. 2005;21(3):958-67. https://doi.org/10.1590/S0102-311X2005000300032
https://doi.org/10.1590/S0102-311X200500...
. A pilot study was carried out from January to June of the same year.

We considered eligible cancer patients, older than 18 years, both men and women and who were receiving chemotherapy for the first time. Patients with nausea or vomiting 24 hours before chemotherapy, who underwent abdominal radiotherapy concomitantly with chemotherapy, and those with inability to verbal communication were excluded. Participants underwent one-day chemotherapy protocols, followed up in the first treatment cycle until the fifth day after chemotherapy infusion, and they were interviewed again in the next chemotherapy cycle.

In the first stage of the expanded research project, a structured questionnaire containing questions on socioeconomic, demographic, clinical, and quality of life (EuroQol Research Foundation 5 Dimensions and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 version 3.0) was answered by patients undergoing the first cycle of chemotherapy. Both questionnaires were validated for Brazilian Portuguese. The quality of life results will be described in later publications.

In the second stage, on the return to perform the second cycle of chemotherapy, data on quality of life were collected again, and the patients delivered the questionnaire of the experiences of nausea and vomiting in the period of five days. The presence of nausea and vomiting (yes/no) and the number of vomiting episodes per day were measured. Patients who did not return for the second cycle of chemotherapy were contacted by telephone and their medical records were reviewed to verify the reason for the loss to follow-up. Clinical variables of interest were also collected from medical records. The explanatory variables used were: gender, race/skin color, age, marital status, schooling, primary neoplasia, stage, presence of metastasis, alcohol and/or tobacco consumption, radiotherapy, source for treatment costing and antiemetic regimen in the late phase. The control variables were: emetogenic chemotherapy, treatment hospital and antiemetic regimen in the acute phase. The outcome variables were: acute and late nausea, acute and late vomiting.

Complete response to nausea and vomiting was defined as absence of nausea and vomiting. Complete response to vomiting was defined as no occurrence of vomiting. Absence of nausea defined a complete response to nausea. It was considered as acute phase up to 24 hours from the beginning of chemotherapy infusion, from 24 hours to five days was considered a late phase, and from beginning of chemotherapy infusion to the fifth day, the total phase. Antiemetic prophylaxis was classified as adequate or inadequate according to the international protocol of MASCC and ESMO55. Roila F, Herrstedt J, Aapro M, Gralla RJ, Einhorn LH, Ballatori E, et al. Guideline update for MASCC and ESMO in the prevention of chemotherapy-and radiotherapy-induced nausea and vomiting: results of the Perugia Consensus Conference. Ann Oncol. 2010;21 Suppl 5:v232-43. https://doi.org/10.1093/annonc/mdq194
https://doi.org/10.1093/annonc/mdq194...
.

The sample was estimated considering the patients in their exposure group in HEC and MEC (Openepi® program),95% confidence level; 95% power; and percentage of positive exposures provided by the literature (HEC 90%, MEC 60%). The estimated sample consisted of 116 participants, 58 for each group.

Descriptive and inferential statistical analysis was performed. In the bivariate analysis, the chi-square test (X22. Singh P, Yoon SS, Kuo B. Nausea: a review of pathophysiology and therapeutics. Therap Adv Gastroenterol. 2016;9(1):98-112. https://doi.org/10.1177/1756283X15618131
https://doi.org/10.1177/1756283X15618131...
) or Fisher's exact test were used. McNemar test was used for dependent samples. The multiple models (acute phase, late phase and total phase) were controlled by the variables “hospital,” “emetogenic chemotherapy,” and “antiemetic” in the acute phase. The variables presenting p-value < 0.20 in at least one of the phases of bivariate analysis and absence of collinearity participated in the multiple logistic regression model. A p < 0.05 was considered as statistically significant value. The statistical analyses were conducted using the Statistical Package for the Social Sciences, version 20.

The study was approved by the Research Ethics Committee of the Universidade Federal de Minas Gerais and by the co-participating hospitals (Certificate of Presentation for Ethical Appreciation – CAAE: 36059514.5.0000.514). All participants signed the informed consent form. The illiterate gave their consent by fingerprinting, and the term was read in the presence of a relative.

RESULTS

In total, 549 patients started outpatient treatment with chemotherapy in the three hospitals, during the study period. A total of 201 patients were excluded at the beginning of data collection. The reasons for exclusion were: age ≤ 18 years (two patients); previous chemotherapy (66 patients); nausea/vomiting in the previous 24 hours (19 patients), abdominal radiotherapy (18 patients), drug-induced drowsiness (23 patients), inability to communicate (52 patients); refusal to participate (15 patients), and chemotherapy for another disease (six patients).

Thus, 348 patients were eligible for follow-up, and 49 patients were lost to follow-up. The reasons for loss to follow-up were: discontinuation of chemotherapy treatment (12 patients); death (two patients); incomplete questionnaire (29 patients); and hospitalization for chemotherapy in the second cycle (six patients). The final analysis was performed with 269 participants, 152 undergoing HEC and 117 undergoing MEC. However, we present the descriptive analysis for the sample with all emetogenic chemotherapies followed. The other participants underwent other emetogenic chemotherapies.

Most participants were women, with a mean age of 55.2 years, brown-skinned, married, with an average 6.2 years of schooling and undergoing chemotherapy with HEC. Breast cancer was the most frequent primary neoplasm. The sociodemographic, clinical, and treatment-related characteristics are shown in Table 1.

Table 1
Distribution of clinical, sociodemographic, life habits and emetogenic chemotherapy of chemotherapy characteristics. Belo Horizonte (MG), Brazil, 2015.

The chemotherapy protocols were: CDDP (Cisplatin), 87 (32.3%); AC (Cyclophosphamide < 1500mg/m2 and Doxorubicin), 49 (18.2%); CDDP-P (Cisplatin and Paclitaxel), 23 (8.6%); Carboplatin and Paclitaxel, 21 (7.8%); FOLFOX (5-Fluouracil and Leucovorin), 18 (6.7%); Cisplatin and Fluouracil, 11 (4.1%); PE (Cisplatin and Etoposide), 7 (2.6%); R-CHOP, 4 (1.5%); FLOX, 4 (1.5%); and others, 45 (16.7%).

The prophylaxis of prescribed antiemetics was inadequate for the acute phase and for the late phase, considering the MASCC and ESMO protocol for all patients.

Note that, in the acute phase, all patients received prophylactic infusion of intravenous antiemetics in the hospital. Out of these, 151 (99.3%) patients undergoing chemotherapy with HEC and 117 (100%) patients undergoing chemotherapy with MEC received ondansetron (5-HT3RA). Dexamethasone was administered to 149 (98%) patients undergoing HEC chemotherapy and in 114 (97.4%) undergoing MEC. Also, ranitidine was administered to 31 (20.4%) patients undergoing chemotherapy with HEC and to 31 (26.5%) patients undergoing MEC. Omeprazole was administered to 10 (6.6%) patients, dimehydrinate to 16 (10.5%) and metoclopramide to 12 (10.3%). No patient received neurokinin antagonist (NK1).

In the late phase, 139 (91.4%) patients undergoing chemotherapy with HEC and 103 (88%) of the patients undergoing MEC chemotherapy were prescribed antiemetics for consumption at home. Ondansetron was prescribed for 111 (79.9%) patients undergoing chemotherapy with HEC and 90 (87.4%) patients undergoing MEC. Dexamethasone was prescribed for 61 (43.9%) and 52 (50.5%) patients undergoing HEC and MEC, respectively. Metoclopramide was prescribed for 100 (71.9%) patients undergoing HEC and for 68 (66%) patients undergoing MEC. Omeprazole was prescribed for 10 (7.2%) and 11 (10.7%) undergoing HEC and MEC, respectively. Bromopride was prescribed for 9 (6.5%) and 6 (5.8%) undergoing HEC and MEC, respectively. Dimenhydrinate was prescribed for 15 patients (nine HEC and six MEC), diphenhydramine for four patients, bromopride for two (one HEC and one MEC), domperidone for 1 patient undergoing MEC and draminate for four (three MEC and one HEC. NK1 antagonist was not prescribed for any patient.

The incidence of nausea for all participants in the total phase was 58%, and the incidence of vomiting was 32.7%. In the acute phase, the incidence of nausea was 31%, and vomiting was 11.2%. The incidence of nausea in the late phase was 54.6%, and vomiting was 29.3%.

The incidence of nausea for HEC and MEC in the total phase was 63.2% and 51.3%, and vomiting was 45.8% and 19.7%, respectively. In the acute phase, the incidence of nausea for HEC and MEC was 35.1% and 25.6%, and vomiting was 15.2% and 6%, respectively. In the late phase, the incidence of nausea for HEC and MEC was 59.2% and 48.7%, and vomiting was 38.8% and 17.1%, respectively.

The daily relative frequency showed that, for both outcomes, participants undergoing chemotherapy with HEC presented higher values when compared with patients undergoing MEC chemotherapy. The daily relative frequency of CINV is shown in Figure 1.

Figure
Relative frequency of nausea and vomiting during the five-day period after chemotherapy infusion. Belo Horizonte (MG), Brazil, 2015.

The relative frequency of nausea was higher when compared with vomiting in the acute phase (p < 0.001) and in the late phase (p < 0.001).

In the acute phase, among the 11.2% of patients who had vomiting, the mean number of vomiting was 2.7; median of 2.0, minimum of 1 and maximum of 7 vomiting. In the late phase, among the 29.3% of patients who had vomiting, the average number was 16; median of 13, minimum of 5 and maximum of 32 vomiting.

The proportion of complete responses for nausea and vomiting was statistically different between the emetogenic chemotherapies, for the total phase. In the acute phase, a statistically significant difference was observed only for the complete response to vomiting between the two groups of emetogenic chemotherapy. In the late phase, there was a difference between the groups of patients who received HEC and MEC for vomiting, as shown in Table 2.

Sociodemographic, clinical factors, lifestyle habits, and treatments associated with complete response to antineoplastic chemotherapy-induced nausea and vomiting were stratified by treatment phase, and they are presented in Table 3.

Table 3
Complete response to nausea/vomiting according to sociodemographic, clinical, and treatment phase variables. Belo Horizonte (MG), Brazil, 2015.

In the bivariate analysis, differences in the complete response to CINV were observed in the acute phase regarding the variables tobacco use and hospital treatment. In the acute phase, a lower proportion of complete response was identified in Hospital 2 (64.7%) compared with the other two hospitals, and among smokers (41.9%), compared with patients who had never smoked or who are former smokers. In the total phase, the variables age group and emetogenic chemotherapy showed statistically significant differences. In the total phase, the age group younger than 49 years had a lower incidence of complete response (32.9%), and patients undergoing chemotherapy with HEC had lower complete response (32.2%) compared with patients undergoing MEC. The bivariate analysis can be verified in Table 3.

In the total phase, the lower age groups (≤ 49 years and 50–64 years) decreased the complete response compared with the upper age group (≥ 65 years) – odds ratio (OR) = 0.47; 95% confidence interval (95%CI) 0.23–0.95 versus OR = 0.45; 95%CI 0.23–0.87. The complete response also increases in this phase when we compare patients who have never smoked with former smokers (OR = 1.91; 95%CI 1.02–3.57). Also in this phase, the complete response decreased in patients undergoing chemotherapy with HEC, when compared with patients undergoing MEC (OR = 0.55; 95%CI 0.31–0.95).

Multiple logistic regression showed that, in the acute phase, smoking decreases the complete response compared to patients who had never smoked (OR = 0.35; 95%CI 0.14–0.88). Hospital 1 showed a better complete response in the acute phase, when compared to Hospital 3 (OR = 2.71; 95%CI 1.14–6.42).

In the late phase, the complete response decreases in patients undergoing chemotherapy with HEC, when compared with patients undergoing MEC (OR = 0.56; 95%CI 0.32–0.97). The variables inserted in the multiple logistic regression model are presented in Table 4.

DISCUSSION

The sample was mostly composed of women, with stage III breast cancer, aged between 50 and 64 years, married, with up to four years of schooling, former smokers and former alcoholics, with treatment funded by the Unified Health System (SUS). The incidence of nausea for both emetogenic chemotherapies in the total phase was 58%, and the incidence of vomiting was 32.7%.

Breast cancer was the most frequent in women (33.1%), as found in prospective observational studies that evaluated CINV99. Bloechl-Daum B, Deuson RR, Mavros P, Hansen M, Herrstedt J.

https://doi.org/10.1016/j.clbc.2017.11.0...
. Furthermore, 94.1% of chemotherapy costs was funded by SUS, and 67.9% of the patients presented themselves with advanced stage of the disease (stage III and IV), initiating chemotherapy treatment. These data corroborate the official estimate of cancer incidence in Brazil, in which it is emphasized that cancers, including breast cancers, which have screening, are diagnosed in an advanced stage1717. Renna Junior NL, Silva GAE. Late-stage diagnosis of breast cancer in Brazil: analysis of data from hospital-based cancer registries (2000-2012).

.

The incidence of CINV in the acute phase was lower than in the late phase, with a peak on the third day (43.5%) after chemotherapy infusion, for both emetogenic chemotherapies. A similar result was highlighted in previous studies, in which the incidence of nausea and vomiting was lower in the acute phase99. Bloechl-Daum B, Deuson RR, Mavros P, Hansen M, Herrstedt J.

Nausea is a subjective adverse effect, but it is more frequent than vomiting, and with the potential for worsening quality of life and nutritional status of patients undergoing chemotherapy1818.

(46%) which was composed of patients who were also undergoing both emetogenic chemotherapies (HEC and MEC). The occurrence of late nausea (54.6%) was also lower than that reported in the aforementioned study, which found an incidence of 82.7%1313. Rha YS, Park Y, Song SK, Lee CE, Lee J.

In our study, the complete response to vomiting was 61.2% and nausea was 40.8% in patients undergoing HEC in the acute phase. Higher frequencies for complete vomiting response (86%) and nausea (81%) have been observed in previous studies1212. Hsieh RK, Chan A, Kim HK, Yu S, Kim JG, Lee MA, et al.

. When comparing the incidence of late vomiting by emetogenic chemotherapy (HEC: 38.8% and MEC: 17.1%) we also found a higher proportion than that found by other authors (19.2% for HEC and 16.1% for MEC)1212.

The complete response to vomiting in the total phase was 57.2% for patients undergoing HEC and 80.3% for patients undergoing MEC. In a previous study1212. Hsieh RK, Chan A, Kim HK, Yu S, Kim JG, Lee MA, et al.

, the complete response to vomiting was 74.8% in patients undergoing HEC, a percentage higher than that found in this study. However, the complete response for patients undergoing MEC was similar, 80%1212. Hsieh RK, Chan A, Kim HK, Yu S, Kim JG, Lee MA, et al.

.

The complete response to CINV in the total phase was observed for 38.7% of the patients, after undergoing antineoplastic chemotherapy with HEC and MEC. This proportion was lower when compared with those found in previous studies, in which the complete response in the first cycle was 53.4%21 and 69%1212.

In our study, no patient received an antiemetic regimen with NK1 receptor antagonist. In a previous study1313. Rha YS, Park Y, Song SK, Lee CE, Lee J. Controlling chemotherapy-induced nausea requires further improvement: symptom experience and risk factors among Korean patients. Support Care Cancer. 2016;24(8):3379-89. https://doi.org/10.1007/s00520-016-3146-x
https://doi.org/10.1007/s00520-016-3146-...
, the antiemetic regimen 5-HT3RA + dexamethasone was prescribed for 62.9% patients, and the 5-HT3RA regimen was prescribed for 18.2%, and 78.6% of patients received antiemetic regimen recommended by the protocol. In another study2121. Molassiotis A, Aapro M, Dicato M, Gascon P, Novoa SA, Isambert N, et al. Evaluation of risk factors predicting chemotherapy-related nausea and vomiting: results from a European prospective observational study. J Pain Symptom Manage. 2014;47(5):839-48.e4 https://doi.org/10.1016/j.jpainsymman.2013.06.012
https://doi.org/10.1016/j.jpainsymman.20...
, during the first cycle of chemotherapy, the adequacy of antiemetic prescription to the protocol was 63.4% in the acute phase and 59.7% in the late phase.

Note that antiemetic regimens are not prescribed according to protocols. We found no association between the prescribed regimens and the complete response for different phases analyzed. Note that more recent studies have shown that antiemetic regimens composed of the association of 5-HT3RA + NK1 antagonist and corticosteroids have better controlled CINV in both acute and late phases2222.

The lower age groups (≤ 49 and 50-64 years) were a risk factor for CINV. These results were similar in previous studies, in which age groups below 50–55 years showed worsening of the complete response to CINV1414.

A previous study showed that CINV were less frequent among smoking patients compared with non-smokers2626. Esra YE, Aziz Y, Zeki U, Gülsah G, Mert B, Yesim E, et al. Is chemotherapy-induced nausea and vomiting lower in smokers? Int J Clin Pharmacol Ther. 2011;49(12):709-12.. In our study, in the late and total phases, there was an inverse association between former smokers and presenting a better complete response, compared to patients who had never smoked. Previous contact with tobacco and non-current smoking was a negative factor for CINV. However, one study emphasized the harms of smoking for cancer patients undergoing chemotherapy, among them: weight loss, skin and sleep complications and incidence of nausea, compared with patients who did not smoke2727. Peppone LJ, Mustian KM, Morrow GR, Dozier AM, Ossip DJ, Janelsins MC, et al. The effect of cigarette smoking on cancer treatment-related side effects.

No evidence was found relating women as a risk factor for CINV, which corroborates the previous result2121. Molassiotis A, Aapro M, Dicato M, Gascon P, Novoa SA, Isambert N, et al.

No difference in CINV was found between users and non-users of alcohol. The consumption of five or more doses of alcohol per week was associated with complete response to vomiting in a previous study2828. Hesketh PJ, Aapro M, Street JC, Carides AD. Evaluation of risk factors predictive of nausea and vomiting with current standard - of care antiemetic treatment: analysis of two phase III trials of aprepitant in patients receiving cisplatin-based chemotherapy. Support Care Cancer. 2010;18(9):1171-7. https://doi.org/10.1007/s00520-009-0737-9
https://doi.org/10.1007/s00520-009-0737-...
. Another study found an association, in the first cycle of chemotherapy, for patients who consumed more than 11 doses of alcohol per week for the outcome of acute vomiting, compared with patients who did not consume alcohol or doses per week, with the highest alcohol consumption being a protective factor against CINV. Alcohol consumption was not associated with a difference in response to NCIV in previous literature2424. Mizuno M, Hiura M, Kikkawa F, Numa F, Yaegashi N, Narahara H, et al. A prospective observational study on chemotherapy-induced nausea and vomiting (CINV) in patients with gynecologic cancer by the CINV Study Group of Japan.

Hospital 1 has a characteristic that differentiates it, which may have influenced the increase in the complete response to acute phase compared with Hospital 3. An association was found between the hospital and the antiemetic regimen administered to the patient in the acute phase. Hospital 1 patients received 5-HT3RA + corticosteroid + other antiemetic regimen (closer to what is recommended by the MASCC and ESMO protocols) in 39.3% of the cases.

Some factors not researched until now may have influenced the improvement of complete response to nausea and vomiting in the acute phase in Hospital 1, compared with Hospital 3. Specifically for the control of nausea and vomiting, the physical structure of the chemotherapy rooms (ventilation, odors, stay of the patients’ companion) can be highlighted. The cerebral cortex identifies some factors related to the hospital environment that can induce nausea and vomiting33. Puri S, Hyland KA, Weiss KC, Bell GC, Gray JE, Kim R, et al. Prediction of chemotherapy-induced nausea and vomiting from patient-reported and genetic risk factors. Support Care Cancer. 2018;26(8):2911-8. https://doi.org/10.1007/s00520-018-4120-6
https://doi.org/10.1007/s00520-018-4120-...
. Previous studies have found an association between the support of the caretaker/family member perceived by the patient and the response to NCIV control2929. Zook DJ, Yasko JM. Psychologic factors: their effect on nausea and vomiting experienced by clients receiving chemotherapy. Oncol Nurs Forum. 1983;10(3):76-81.. It is known that other resources may influence the control of nausea and vomiting, such as acupuncture, ginger consumption, fractional and cold feeding, and relaxation and distraction techniques – which was not investigated in this study and may have predominated in the participants of Hospital 13030. Sheikhi MA, Ebadi A, Talaeizadeh A, Rahmani H. Alternative methods to treat nausea and vomiting from cancer chemotherapy. Chemother Res Pract. 2015;2015:818759. https://doi.org/10.1155/2015/818759
https://doi.org/10.1155/2015/818759...
.

Among the limitations of our study, the absence of any measure on dose of alcohol consumption stands out. The variable “use of antiemetic rescue use” in households was not used, as there could be memory bias of the participants (the use of medications was not included in the recall questionnaire of the experiences of nausea and vomiting).

In this study, the incidence of nausea was higher than that of vomiting, and the late phase had a higher frequency of both adverse effects. The results suggest that tobacco, young age and high emetogenic chemotherapy are among the risk factors for episodes of CINV. The treatment occurring in Hospital 1 was related to a better complete response in the acute phase compared to Hospital 3. All patients received antiemetic prophylaxis in the acute phase, although the prescription of antiemetic regimens did not meet the protocols used in this study as a reference for patients undergoing high and moderate emetogenic chemotherapy.
