Summary
Nausea and vomiting are common complications on the chemotherapy (CT) and can affect the quality of life (QoL) of the patients. If not treated adequately it can produce other problems such as dehydration, weight loss, fatigue and even can induce the non-compliance of the treatment. In extreme cases it can put the patient ́s life at risk. There are various antiemetic treatments that vary both in cost and effectiveness. It ́s important to determine which are the strategies that are most effective and can improve the QoL of the patients. Methodology: The analysis will be done in patients who receive adjuvant and neoadjuvant chemotherapy and that have not received previously chemotherapy or radiotherapy, they will be stratified according to the emetogenic potential of the CT. They were given a diary of symptoms to register any discomfort suffered after receiving their treatment and also a quality of life questionnaire was applied previous to their first cycle and previous to their second cycle. The patients were divided in two groups receiving either A scheme (palonosetron) or B scheme (ondansetron) in combination with dexamethasone and fosaprepitant for prevention of early emesis and Dexamethasone to group A or Dexamethasone + metoclopramide to group B for prevention of delayed emesis. As well It was analyzed the three most prevalent single nucleotide polymorphisms (SNPs) on gene ABCB1 using PCR. The aim of this study is to evaluate the efficacy and quality of life provided by the 2 regimes noted above based on Mexican population so the results obtained can be applied widely in our country.
