Factors Affecting the Comprehension of Outpatients Receiving Cancer Chemotherapy.

Pharmaceutical consultation targeting outpatients at the Fujita Health University Hospital (Japan) provides support to patients undergoing anticancer drug treatment. This study aimed to explore factors that affect the comprehension of cancer chemotherapy among outpatients who received cancer treatment at our hospital. A questionnaire survey was conducted, and comprehension was scored on a scale of 1-5 (1, no comprehension; 5, full comprehension). When factors other than age and sex [the influence of which on comprehension has been reported in previous reports] were noted, differences in comprehension between the questionnaire items were comparatively analyzed according to the presence/absence of the relevant factors. Overall, 536 patients were included. Age (<70 years) and pharmacist interventions were identified as factors contributing to a comprehension score. The levels of comprehension regarding the name of the cancer chemotherapy, content/schedule of the treatment, purposes of the prescribed drugs, and objectives of blood tests were significantly higher in the group that received the pharmaceutical interventions; conversely, the level of comprehension for the self-management of adverse events was significantly lower in this group than in the group that did not receive any pharmaceutical interventions. Age and interventions by the pharmacist affected the comprehension of cancer chemotherapy by patients.

Pharmaceutical intervention for adverse events improves quality of life in patients with cancer undergoing outpatient chemotherapy.

BACKGROUND: The effect of pharmaceutical intervention to treat adverse events on quality of life (QOL) in outpatients receiving cancer chemotherapy is unclear. We investigated whether pharmaceutical intervention provided by pharmacists in collaboration with physicians improves QOL with outpatient cancer chemotherapy. METHODS: We conducted a single-center retrospective descriptive study of pharmaceutical intervention for patients receiving outpatient cancer chemotherapy at Gifu University Hospital between September 2017 and July 2020. We assessed patient QOL using the Japanese version of the EuroQol 5 Dimension5 Level (EQ-5D-5L). Adverse events were graded using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. We compared the EQ-5D-5L utility value and incidence of grade 2 or higher adverse events before and after pharmaceutical intervention. RESULTS: Our analysis included 151 patients who underwent 210 chemotherapy cycles. Pharmaceutical intervention significantly improved patients' EQ-5D-5L utility values from 0.8197 to 0.8603 (P < 0.01). EQ-5D-5L utility values were significantly improved after pharmaceutical intervention for nausea and vomiting (pre-intervention 0.8145, post-intervention 0.8603, P = 0.016), peripheral neuropathy (pre-intervention 0.7798, post-intervention 0.7988, P = 0.032) and pain (pre-intervention 0.7625, post-intervention 0.8197, P = 0.035). Although not statistically significant, the incidence of grade 2 or higher adverse events, including nausea and vomiting, dermopathy, pain, oral mucositis, diarrhea and dysgeusia, tended to be lower post-intervention than pre-intervention. CONCLUSIONS: Pharmaceutical intervention by pharmacists in collaboration with physicians may improve QOL in patients undergoing outpatient cancer chemotherapy.

Risk Factors Associated With Unplanned Acute Care in Outpatient Chemotherapy With Oral Anticancer Drugs as Monotherapy or Combination Therapy With Injectable Anticancer Drugs.

BACKGROUND/AIM: Recently, the number of patients with cancer receiving outpatient chemotherapy using oral anticancer drugs has increased, but the currently available outpatient cancer chemotherapy is not safer than that available before. The present study aimed to identify risk factors associated with unplanned acute care (UAC) requiring outpatient chemotherapy-related consultation and hospitalisation. PATIENTS AND METHODS: We conducted a case- control study among 1,674 patients who received oral anticancer drug treatment either alone or in combination with injectable anticancer drugs at National Cancer Center Hospital East, Japan, between December 1, 2014, and November 30, 2015. RESULTS: Body mass index (BMI) was identified as a risk factor for UAC during chemotherapy. Patients with a BMI of <18.5 kg/m2, classified as underweight according to the World Health Organization classification of nutritional status, had a significantly higher risk of UAC. CONCLUSION: A low BMI immediately before the occurrence of chemotherapy-related UAC is a risk factor for adverse effects; therefore, underweight patients need more careful monitoring and supportive care.

Anorexia, pain and peripheral neuropathy are associated with a decrease in quality of life in patients with advanced pancreatic cancer receiving outpatient chemotherapy - a retrospective observational study.

BACKGROUND: Cancer chemotherapy usually improves clinical outcomes in patients with advanced pancreatic cancer (APC), but can also cause moderate-to-severe adverse events (AEs). We investigated the relationship between moderate-to-severe AEs and quality of life (QOL) in patients with APC who received outpatient chemotherapy. METHODS: We recruited APC patients who received outpatient chemotherapy in Gifu University Hospital between September 2017 and December 2018. Adverse events related to chemotherapy were assessed by a pharmacist collaborating with a physician using common terminology criteria for AEs (CTCAE) ver 4.0, and QOL of patients was self-assessed by patients using the five-level EuroQol five-dimensional questionnaire (EQ-5D-5L Japanese edition 2). Associations between the EQ-5D-5L utility value and serious AEs were assessed using proportional odds logistic regression. RESULTS: A total of 59 patients who received 475 chemotherapy cycles were included. The proportional odds logistic regression indicated that grade ≥ 2 anorexia, pain and peripheral neuropathy were significantly correlated with a decreased EQ-5D-5L utility value. Pharmaceutical intervention for these AEs significantly improved the patients' EQ-5D-5L utility value. CONCLUSIONS: Anorexia, pain and peripheral neuropathy were significantly associated with a decrease in QOL. It is assumed that appropriate pharmaceutical intervention with particular emphasis on these AEs can improve the QOL of pancreatic cancer patients receiving outpatient chemotherapy.

Real-world data of the association between quality of life using the EuroQol 5 Dimension 5 Level utility value and adverse events for outpatient cancer chemotherapy.

BACKGROUND: Outpatient cancer chemotherapy may lead to improved quality of life (QOL) by allowing treatment to continue without impairing the social lives of patients compared with hospitalization. However, the occurrence of serious adverse events may cause a decline in QOL. We investigated the relationship between outpatient chemotherapy-induced adverse events and QOL. METHODS: A single-center retrospective descriptive study was conducted in patients who received outpatient chemotherapy at Gifu University Hospital (Gifu, Japan) between September 2017 and December 2018. The utility values of QOL, type and severity of adverse events, type of cancer, chemotherapy regimen, and other patient demographics were analyzed. Adverse events were graded according to the Common Terminology Criteria for Adverse Events, version 4.0. QOL was evaluated using the Japanese version of the EuroQol 5 Dimension 5 Level (EQ-5D-5L). Associations between the EQ-5D-5L utility value and serious adverse events were assessed using adjusted (age and sex) odds ratios obtained with a proportional odds logistic regression model. RESULTS: Data from 1008 patients who received 4695 chemotherapy cycles were analyzed. According to proportional odds logistic regression, the adverse events that significantly correlated with a decreased EQ-5D-5L utility value were malaise, edema of the limbs, peripheral neuropathy, pruritus, and dry skin. Based on the proportional odds logistic analysis, neither cancer type nor anticancer drugs were significantly correlated with the EQ-5D-5L utility value in patients who received chemotherapy. Pharmaceutical care for peripheral neuropathy significantly improved patients' EQ-5D-5L utility value from 0.747 to 0.776 (P < 0.01). CONCLUSIONS: Adverse events (i.e., peripheral neuropathy, malaise, and edema of the limbs) are significantly correlated with a decrease in QOL, regardless of the type of cancer or anticancer drugs used. Pharmaceutical care provided by pharmacists in collaboration with physicians may improve QOL.

Alleviating Distress in Outpatients Undergoing Chemotherapy: Analysis of Resources Required for Palliative Cancer Care Delivery

This study aimed to clarify the resources required to relieve distress during palliative care delivery to cancer patients. Between April 2015 and March 2017, 1479 outpatients receiving chemotherapy for cancer were screened using the Japanese version of the Support Team Assessment Schedule (STAS-J). When the STAS-J result was 2 points and higher, the patient was considered positive for distress. A certified nurse or pharmacist performed STAS-J screening and, in cases where the patient exhibited distress, took steps to alleviate the problem themselves or consulted another resource. Distress was identified in 181 (12.2%) of the 1479 patients. These 181 patients needed 288 resources. The resources used to alleviate distress were categorized as follows: direct support by certified nurse or pharmacist (153), consultation with the attending physician (98) and other (37). The required resource included the following twelve professionals: attending physician, ophthalmologist, dermatologist, dentist, orthopedic surgeon, palliative care physician, certified nurse, certified pharmacist, medical social worker, clinical psychologist, volunteers for cancer patients, and palliative care team. The frequency of the intervention by the certified nurse or pharmacist (61, 39.9%) in directly alleviating psychiatric distress was significantly higher than by consultation with the attending physician (10, 10.2%) (p<0.0001). However, the frequency of consultation with the attending physician in alleviating physical distress (88, 89.8%) was significantly higher than that of the certified nurse or pharmacist (92, 60.1%) (p<0.0001). We conclude that the certified nurse or pharmacist is important for the delivery of palliative cancer care, because they can directly provide relief from psychiatric distress.

Comparison of the Control of Nausea and Vomiting among Several Moderately Emetic-Risk Chemotherapy Regimens.

BACKGROUND: Different antiemetic medications with or without aprepitant are recommended for moderately emetic-risk chemotherapy (MEC) depending on the emetic potential of chemotherapy agents, although the criterion for the use of aprepitant is still unclear. The present study was designed to compare the control of chemotherapy-induced nausea and vomiting (CINV) among several MEC regimens used in the outpatient chemotherapy setting. MATERIALS AND METHODS: A single center prospective observational study was carried out in 326 patients who received 2,061 chemotherapy cycles from January 2013 to December 2014. Antiemetic medication consisting of two-drug combination of granisetron (day 1) and dexamethasone (days 1-3) was carried out in 87.6% of patients receiving the first chemotherapy cycle. The checklist for CINV was provided to all patients, and the control of CINV was evaluated on the next visit based on the checklist. Complete inhibition of nausea and vomiting during acute and delayed periods were compared among MEC regimens. RESULTS: Two hundred and one patients received the first cycle of chemotherapy, in which the rates of complete inhibition of nausea and vomiting were 87.6% and 95.5%, respectively, during acute period, and 68.2% and 92.0%, respectively, during delayed period. There were no significant differences in the control of CINV among oxaliplatin, carboplatin and irinotecan, except for the cyclophosphamide-base regimen. CONCLUSIONS: Two-drug antiemetic medication of 5-HT3 receptor antagonist and dexamethasone was sufficiently effective for prevention of CINV in most MEC regimens.

Control of chemotherapy-induced nausea in patients receiving outpatient cancer chemotherapy.

BACKGROUND: Control of chemotherapy-induced nausea is still incomplete, regardless of adherence to the antiemetic guideline. The present study was designed to assess the control rates of nausea and vomiting in the outpatient chemotherapy clinic and to determine risk factors for nausea. METHODS: A single-center prospective observational study was carried out in 779 patients who received 5511 chemotherapy cycles from January 2013 to December 2014 in the outpatient chemotherapy clinic. A checklist for adverse events was provided to all patients, and nausea and vomiting were monitored on the next visit. Complete protection from nausea and vomiting during acute (within 24 h) and delayed (during 2-7 days) periods was assessed. RESULTS: Under the condition of 76-99 % rates of adherence to the Japanese Society of Clinical Oncology guideline for antiemesis, the rates of complete protection from acute and delayed nausea in the first cycle of chemotherapy were 60 % and 45 %, respectively, for high emetic risk chemotherapy (HEC), and 85 % and 70 % for moderate emetic risk chemotherapy (MEC). The rates were improved in the overall cycles. On the other hand, vomiting was well controlled, in which complete protection ranged from 83 % (HEC) to 99 % (minimum). A multivariate analysis indicated that being female, age less than 60 years, high or moderate risk chemotherapy, and anthracycline/cyclophosphamide (A/C) were significant risks for overall nausea. Indeed, the control of delayed nausea was extremely poor in the first cycle of A/C, although there was no difference in the control of nausea among MEC. CONCLUSION: Antiemetic medication in consideration of the risk factors is required to improve the control of nausea.
