Assessment of chemotherapy-related educational needs of colorectal cancer patients.

AIM: Aim of our study was to evaluate cancer patients' knowledge about their chemotherapy regimens in order to assess educational needs of patients. METHODS: Study was conducted on 58 colorectal carcinoma patients who were treated in an outpatient chemotherapy unit. These patients had received a 2-page information pamphlet about their chemotherapy treatments before the commencement of treatment. During the first interview with patients, pharmacist collected demographic data and evaluated patients' knowledge about their medications using a standardized questionnaire. FINDINGS: Mean age of the patients was 59.6 ± 1.3 years; 65.5% were male. Majority (77.6%) of patients were graduates of primary school. Sixty-four percent of these had at least one comorbid disease. Median number of chemotherapy courses already received by patients was 4 (1-9). Fifty-nine percent reported that they did not receive any patient education and 43.1% reported that they did not receive any informative document. Twenty-nine percent of patients did not know what actions to take in case of nausea-vomiting; while 53.4% did not know how to react if their body temperature exceeded 38 °C and 25.9% had no idea about dietary necessities. About one-third of patients did not pay attention to oral care. CONCLUSION: Our study showed that patients did not understand (or remember) the basic points about their chemotherapy sufficiently, but remembered the adverse effects they experienced occasionally. Pharmacists will have the chance to increase the level of knowledge of the patients receiving chemotherapy by providing patient education and follow-up.

Real-world assessment of quality-of-life in patients with breast cancer treated with adjuvant endocrine therapy.

Objective: The aim of this study was to investigate quality-of-life (QoL) in breast cancer (BC) patients treated with adjuvant endocrine therapy (AET). Methods: We designed a cross-sectional study of 233 BC patients treated with AET and used the Functional Assessment of Cancer Therapy - Breast questionnaire. Results: No significant difference was observed between endocrine agents. Duration of AET did not affect QoL. In the entire cohort, multivariate analysis determined age (p = 0.034) and switching treatment from tamoxifen to aromatase inhibitors (p = 0.049) as significant positive coefficients of QoL, while comorbidity (p = 0.072) tended to be associated with lower scores. Education level (p = 0.001) and chemotherapy (p = 0.04) were significant predictors of QoL in the tamoxifen group, while comorbidity (p = 0.04), surgery type (p = 0.02), radiotherapy (p = 0.006) and stage (p = 0.009) had a significant impact on QoL in aromatase inhibitors group. Conclusion: Evaluating the well-being of BC patients by QoL questionnaires is of great importance to identify particular subgroups that may require supportive care.

Breast cancer (BC) remains the most common cancer among women worldwide. Hormone receptor-positive (estrogen receptor- and/or progesterone receptor-positive) BC represents 70% of all cases. Advances in the treatment of disease lead to improved patient survival. As a result, quality-of-life (QoL) becomes a major concern in clinical practice. This study aimed to assess the impact of socio-demographic, clinical and treatment-related factors on QoL among patients with BC treated with adjuvant endocrine therapy. We used the Functional Assessment of Cancer Therapy ­ Breast questionnaire to evaluate QoL. In the entire cohort, multivariate analysis determined age and switching treatment from tamoxifen to aromatase inhibitors to be significant positive coefficients of QoL, while comorbidity tended to be associated with lower scores. Education level and chemotherapy were significant determinants of QoL in the tamoxifen group, while comorbidity, surgery type, radiotherapy and disease stage had a significant impact on QoL in the aromatase inhibitor group. These findings can be utilized to identify certain subgroups that may need greater supportive care.

Translation, validity, and reliability of NUTRISCORE: The nutrition risk assessment screening test for Turkish cancer patients.

PURPOSE: The aim was to determine the validity and the reliability of the Turkish version of the screening test named NUTRISCORE in cancer patients. METHODS: The language validity of the Turkish form of the study scale was provided by the translationback-translation method. NUTRISCORE and nutritional risk screening (NRS)-2002, malnutrition screening tool (MST), and European Diagnostic Criteria (EDC) were administered to 240 volunteers in oncology clinics, and receiver operating characteristic curves (ROC) were calculated for the validity and reliability analysis. Cohen's kappa coefficient was used to determine the fit between the screening tests. RESULTS: Thirteen experts were consulted for scale content validity, and the content validity index was found to be 0.94. The scale was administered to 67 patients with 4-week intervals for test-retest reliability, and a positive, high-level and statistically significant relationship was found between the two measurements (r = 0.971, P < 0.01). Compared with the reference test NRS-2002, the specificity values of NUTRISCORE, MST, and EDC screening tests were found to be 100%, 83%, and 91%, whereas the sensitivity values of same screening tests were calculated as 85%, 91% and 81%, respectively. According to Cohen's kappa statistics, the kappa agreement between NRS-2002 and NUTRISCORE was 0.88, the kappa agreement between NRS-2002 and MST was 0.34, and it was found to be 0.73 for NRS-2002 and EDC. CONCLUSION: The nutrition screening test named NUTRISCORE showed adequate validity and reliability in Turkish and can detect malnutrition risk of cancer patients treated in oncology clinics as a screening tool.

Response Assessment With Molecular Characterization of Circulating Tumor Cells and Plasma MicroRNA Profiling in Patients With Locally Advanced Breast Cancer During Neoadjuvant Chemotherapy.

BACKGROUND: Cells detaching from the primary tumor site are metastasis initiator cells, and the detection of CTC, known as liquid biopsy, is an important test of biomarkers of cancer progression. We investigated the molecular characterization of circulating tumor cells (CTCs), profiled the plasma microRNA (miR) content, and analyzed the relationship with the clinical outcomes by sampling the peripheral blood from patients with locally advanced breast cancer before and after neoadjuvant chemotherapy. PATIENTS AND METHODS: Markers of breast cancer, epithelial-mesenchymal transition (EMT), drug resistance, and stem cells were used for CTC isolation and characterization. Plasma miR profiles were obtained from selected patients with CTC positivity determined using next-generation sequencing. RESULTS: The proportion of CTC, EMT, and stem cell marker positivity was 16.7%, 8.3%, and 25% before and 18.2%, 15.2%, and 9.1% after treatment, respectively. A significant correlation was found between the pretreatment CTCs and ALDH1 positivity (P = .0245). These CTCs with stemness properties were observed in most hormone receptor-positive, human epidermal growth factor receptor 2-negative cases and were also present with a high incidence in cases of early metastasis. miR-146b-5p and miR-199a-5p, which are involved in metastasis, invasion, and EMT, were accompanied by CTC positivity, and miR-4646-3p was associated with the development of early metastasis. CONCLUSIONS: Molecular characterization of CTCs and miR profiling of serial samples from patients with locally advanced breast cancer during neoadjuvant chemotherapy appears to be a very useful in predicting cure and clinical course and might be a key to developing new targeted therapies.

Significance of a clinical pharmacist-led comprehensive medication management program for hospitalized oncology patients.

Background The use of highly toxic drugs in cancer treatment and supportive care medications exposes patients to an increased number of drug-related problems (DRPs). Clinical pharmacists contribute to the optimal use of medications by intervening in identified drug-related problems. Objective To evaluate the relevance of a comprehensive medication management service in oncology patients. Setting Marmara University Teaching and Research Hospital Medical Oncology Ward, Istanbul, Turkey. Methods This prospective study was carried out between December 2015 and April 2016 with adult patients with confirmed malignancy. Comprehensive medication management was performed by the clinical pharmacist throughout the patient's hospital stay. The medication-related data as well as data regarding demographic and general health status of the patients were reviewed for the presence of drug-related problems. The identified problems, interventions and acceptance rate by physicians were recorded with the help of the Pharmaceutical Care Network Europe V6.0 (PCNE) classification. Main outcome measures Number and causes of drug-related problems, nature and acceptance rate of clinical pharmacist interventions and rate of problems solved. Results The study included 137 patients. The mean (SD) age of the patients was 58 (14.6) years. A total of 481 drug-related problems were recorded. The most frequent drug-related problems were 'adverse drug events [including drug interactions]' (n = 376), 'untreated indications' (n = 59) and 'unnecessary drug treatment' (n = 25). Inappropriate combination of drugs was the cause of 73.2% of the total problems. Interventions were made to stop administration of a suitable drug if the combination with another drug was contraindicated while prescribers were mostly informed about major drug interactions. The prescribers approved 93% of the total intervention proposals. The majority (90.9%) of the identified problems were totally solved. Conclusion Integration of clinical pharmacy services through a comprehensive medication management program in oncology will help to reduce the number of drug-related problems.

Assessment of survival and prognostic factors in metastatic colorectal cancer patients treated with first-line bevacizumab-based therapy.

PURPOSE: Colorectal cancer (CRC) is a significant cause of cancer mortality worldwide. Survival has improved with bevacizumab in metastatic CRC treatment. Our purpose was to analyse survival and prognostic factors in metastatic CRC patients treated with first-line bevacizumab-based treatment. METHODS: Files of CRC patients were examined retrospectively and 360 patients treated with first-line bevacizumab were included. Objective response rates (ORRs), median progression-free and overall survival (PFS and OS) of the patients were calculated. Survival was analyzed with the Kaplan-Meier method. Log-rank test and Cox regression model were used for univariate and multivariate analyses, respectively. RESULTS: Median age at diagnosis was 59.5 years. Of the patients 74.4% had initially stage IV disease. Median PFS was 8.5 months, median OS 25.3 months and ORR was 51.4%. ORRs, median PFS and OS of KRAS mutant and wild-type or unknown patients were statistically similar. In left-sided disease, median PFS and OS (9.6 and 27.1 months) were superior compared to right-sided disease (7.3 and 19.4 months) (p=0.005 and 0.02, respectively). Primary disease location, histopathologic grade, primary surgery and metastasectomy affected OS significantly. Histopathologic grade (hazard ratio=1.77, p=0.002) and metastasectomy (hazard ratio=0.48, p=0.001) were independent prognostic factors. CONCLUSIONS: Our study confirmed that after bevacizumab-based treatment, KRAS status might not be a prognostic factor. We have also shown that left CRC have more favorable outcomes than right CRC in bevacizumab therapy. Additionally, even in metastatic setting histopathologic grade of the primary CRC together with metastasectomy are independent prognostic factors.
