Patients' experience of communication and handling of symptomatic adverse events in breast cancer patients receiving adjuvant chemotherapy.

ABSTRACT: Background:The study is based on a national cluster randomized trial investigating the effect of electronic patient-reported outcomes (ePRO) on treatment outcomes in breast cancer patients receiving adjuvant chemotherapy. All 13 oncology departments (11 clusters) treating breast cancer patients in Denmark were randomized to use electronic patient-reported outcomes with real-time clinician feedback (ePRO arm) to track symptoms or usual care for eliciting symptoms using a short paper tracking list (usual care arm). The impact of ePRO on clinical outcomes were examined, which is reported elsewhere. The purpose of the present study was to examine patient-reported experience measure (PREM) regarding communication and handling of side effects/symptoms. Methods:For this sub-study, patient representatives were involved in the development of a PREM questionnaire. Patients enrolled in the cluster randomized trial completed the PREM questionnaire at their last treatment visit. Semi-structured telephone-interviews were performed with a subgroup of patients. The interviews were based on an interview guide comprised of the questions from the PREM questionnaire and aimed to elaborate on the PREM questionnaire data. Results:A 12 item PREM questionnaire was developed in partnership with patient representatives. In total, 439 out of 682 patients (64.4%) included patients completed the PREM questionnaire. Telephone semi-structured interviews were performed with 22 patients. In total, 52% (ePRO arm) and 65% (usual care arm) reported having talked with the oncologist/nurse about their responses in the tracking systems before each chemotherapy cycle. Fewer patients in the ePRO arm compared to the usual care arm experienced side effects/symptoms not included in the side effect questionnaire. Patients experienced high satisfaction with oncologists' and nurses' handling of side effects/symptoms. Conclusions:Patients experienced high satisfaction with oncologists' and nurses' handling of chemotherapy adverse events. The study indicates a need for a more comprehensive side effect questionnaire as tracking system covering more symptoms than the one used in usual care today.

Project description:BackgroundThis study was conducted to compare the reported adverse event (AE) profiles and unexpected use of medical services during chemotherapy between before and after the healthcare reimbursement of AE evaluation in patients with cancer.Patients and methodsUsing the electronic medical record database system, extracted patients with breast, lung, gastric, and colorectal cancers receiving neoadjuvant or adjuvant chemotherapy between September 2013 and December 2016 at four centers in Korea were matched using the 1:1 greedy method: pre-reimbursement group (n = 1084) and post-reimbursement group (n = 1084). Unexpected outpatient department (OPD), emergency room (ER) visit, hospitalization rates, and chemotherapy completion rates were compared between the groups.ResultsThe baseline characteristics were well-balanced between the groups. By chemotherapy cycle, hospitalization (1.8% vs. 2.3%; p = 0.039), and ER visit rates (3.3% vs. 3.9%; p = 0.064) were lower in the post-reimbursement group than that in the pre-reimbursement group. In particular, since cycle 2, ER visit and hospitalization rates were significantly lower in the post-reimbursement group than those in the pre-reimbursement group (2.6% vs. 3.3%; p = 0.020 and 1.4% vs. 2.0%; p = 0.007, respectively), although no significant differences were observed during cycle 1. The OPD visit rates were similar between both groups, regardless of cycles. The post-reimbursement group had a higher proportion of patients who completed chemotherapy as planned than the pre-reimbursement group (93.5% vs. 90.1%; p = 0.006). Post-reimbursement group had more AEs reported, including alopecia, fatigue, diarrhea, anorexia, and peripheral neuropathy, during cycle 1 than the pre-reimbursement group, which significantly decreased after cycle 2.ConclusionThe introduction of healthcare reimbursement for AE evaluation may help physicians capture and appropriately manage AEs, consequently, decreasing hospital utilization and increasing chemotherapy completion rates.

Project description:BackgroundAdjuvant chemotherapy is a standard treatment option for patients with stage III and high-risk stage II colon cancer. Sex is one of several factors responsible for the wide inter-patient variability in drug responses. Amalgamated data on the effect of sex on the toxicity of current standard adjuvant treatment for colorectal cancer are missing.MethodsThe objective of our study was to compare incidence and severity of major toxicities of fluoropyrimidine- (5FU or capecitabine) based adjuvant chemotherapy, with or without oxaliplatin, between male and female patients after curative surgery for colon cancer. Adult patients enrolled in 27 relevant randomized trials included in the ACCENT (Adjuvant Colon Cancer End Points) database, a large, multi-group, international data repository containing individual patient data, were included. Comparisons were conducted using logistic regression models (stratified by study and treatment arm) within each type of adjuvant chemotherapy (5FU, FOLFOX, capecitabine, CAPOX, and FOLFIRI). The following major toxicities were compared (grade III or IV and grade I-IV, according to National Cancer Institute Common Terminology Criteria [NCI-CTC] criteria, regardless of attribution): nausea, vomiting, nausea or vomiting, stomatitis, diarrhea, leukopenia, neutropenia, thrombocytopenia, anemia, and neuropathy (in patients treated with oxaliplatin).ResultsData from 34 640 patients were analyzed. Statistically significant and clinically relevant differences in the occurrence of grade III or IV nonhematological {especially nausea (5FU: odds ratio [OR] = 2.33, 95% confidence interval [CI] = 1.90 to 2.87, P < .001; FOLFOX: OR = 2.34, 95% CI = 1.76 to 3.11, P < .001), vomiting (5FU: OR = 2.38, 95% CI = 1.86 to 3.04, P < .001; FOLFOX: OR = 2.00, 95% CI = 1.50 to 2.66, P < .001; CAPOX: OR = 2.32, 95% CI = 1.55 to 3.46, P < .001), and diarrhea (5FU: OR = 1.35, 95% CI = 1.21 to 1.51, P < .001; FOLFOX: OR = 1.60, 95% CI = 1.35 to 1.90, P < .001; FOLFIRI: OR = 1.57, 95% CI = 1.25 to 1.97, P < .001)} as well as hematological toxicities (neutropenia [5FU: OR = 1.55, 95% CI = 1.37 to 1.76, P < .001; FOLFOX: OR = 1.96, 95% CI = 1.71 to 2.25, P < .001; FOLFIRI: OR = 2.01, 95% CI = 1.66 to 2.43, P < .001; capecitabine: OR = 4.07, 95% CI = 1.84 to 8.99, P < .001] and leukopenia [5FU: OR = 1.74, 95% CI = 1.40 to 2.17, P < .001; FOLFIRI: OR = 1.75, 95% CI = 1.28 to 2.40, P < .001]) were observed, with women being consistently at increased risk.ConclusionsOur analysis confirms that women with colon cancer receiving adjuvant fluoropyrimidine-based chemotherapy are at increased risk of toxicity. Given the known sex differences in fluoropyrimidine pharmacokinetics, sex-specific dosing of fluoropyrimidines warrants further investigation.

Project description:BackgroundPatients may experience nausea and vomiting when undergoing chemotherapy or surgery requiring anesthesia. Serotonin 5-hydroxytryptamine 3 (5-HT3) receptor antagonists are effective antiemetics, yet may cause adverse cardiac events, such as arrhythmia. We aimed to identify interventions that mitigate the cardiac risk of 5-HT3 receptor antagonists.MethodsElectronic databases, trial registries, and references were searched. Studies on patients undergoing chemotherapy or surgery examining interventions to monitor cardiac risk of 5-HT3 receptor antagonists were included. Search results were screened and data from relevant studies were abstracted in duplicate. Risk of bias of included studies was assessed using the Cochrane Effective Practice and Organisation of Care (EPOC) group's risk-of-bias tool. Due to a dearth of included studies, meta-analysis was not conducted.ResultsTwo randomized clinical trials (RCT) and 1 non-randomized clinical trial (NRCT) were included after screening 7,637 titles and abstracts and 1,554 full-text articles. Intravenous administration of different dolasetron doses was examined in the NRCT, while dolasetron versus ondansetron and palonosetron versus ondansetron were examined in the RCT. Electrocardiogram (ECG) was the only intervention examined to mitigate cardiac harm. No differences in ECG evaluations were observed between dolasetron or palonosetron versus ondansetron after 15 minutes, 24 hours, and 1 week post-administration in the 2 RCTs. Four deaths were observed in one RCT, which were deemed unrelated to palonosetron or ondansetron administration. Minor increases in PR and QT intervals were observed in the NRCT for dolasetron dosages greater than 1.2 mg/kg 1-2 hours post-administration, but were deemed not clinically relevant.ConclusionsECG monitoring of chemotherapy patients administered with 5-HT3 receptor antagonists did not reveal clinically significant differences in arrhythmia between the medications at the examined time periods. The usefulness of ECG to monitor chemotherapy patients administered with 5-HT3 receptor antagonists remains unclear, as all patients received ECG monitoring.Trial registrationPROSPERO registry number: CRD42013003565.
