Quality of life in a real-world study of patients with metastatic colorectal cancer treated with trifluridine/tipiracil.

Background: Quality of life (qol) is important for oncology patients, especially for those with late-stage disease. The present study was initiated to address the lack of published prospective data about the qol benefits of trifluridine/tipiracil (ftd/tpi) compared with best supportive care (bsc) in patients with refractory metastatic colorectal cancer (mcrc). Methods: This prospective, cross-sectional, non-interventional study used multidimensional validated scales to evaluate patient-reported qol in two study cohorts of patients and also to measure differences in mcrc-related symptoms and pain in a real-world clinical setting. Results: Our findings demonstrate that patients with refractory mcrc report better overall qol when treated with ftd/tpi than with bsc alone. In that population, statistically significant differences in mean qol measures favoured ftd/tpi over bsc for physical symptom distress, psychological distress, activity impairment, overall valuation of life, and symptomatology. The overall better qol for patients receiving ftd/tpi implies that treatment was well tolerated and was associated with a lower symptom burden. No significant differences for pain were observed between the groups. Conclusions: This study suggests that ftd/tpi is a well-tolerated option for the treatment of patients with refractory mcrc, showcasing the value of capturing real-world qol data in routine clinical practice.

Real-world use of trifluridine/tipiracil for patients with metastatic colorectal cancer in Canada.

Background: Outcomes for patients with metastatic colorectal cancer (mcrc) are improving with the introduction of new treatments. Treatment for patients who are still fit after failure of all available therapies represents a significant unmet need. In the present study, we analyzed real-world treatment patterns for patients enrolled in Health Canada's trifluridine/tipiracil (ftd/tpi) Special Access Program (sap) and Taiho Pharma Canada's Patient Support Program (psp). Methods: Demographic information and clinical treatment data were collected from adults with mcrc who were previously treated with, or were not candidates for, available therapies and who were enrolled in the sap and psp. For all patients, ftd/tpi treatment status, discontinuation reasons, and prior therapies were examined. Results: The analysis included 717 Canadian patients enrolled in the ftd/tpi sap and psp from September 2017 to October 2018. In that cohort, 59.7% were men, median age was 65 years, and median duration of therapy was 77 days (25%-75% interquartile range: 43-106 days). Of treated patients, 67.1% maintained the same dose for the duration of therapy; 28.0% had a dose reduction.On multivariable analysis, duration of therapy was not influenced by sex, age, province, RAS mutation status, or prior therapies. However, prior oxaliplatin-based chemotherapy (capox or folfox) appeared to be associated with higher rates of discontinuation because of death or disease progression. Conclusions: In advanced mcrc, ftd/tpi is a well-tolerated therapy. The large number of patients enrolled in the access programs within a short period of time is reflective of major clinical need in this area, with many patients being eligible and interested in pursuing treatment in the refractory setting.

Rate of EGFR mutation testing for patients with nonsquamous non-small-cell lung cancer with implementation of reflex testing by pathologists.

BACKGROUND: Testing for mutation of the EGFR (epidermal growth factor receptor) gene is a standard of care for patients with advanced nonsquamous non-small-cell lung cancer (nsclc). To improve timely access to EGFR results, a few centres implemented reflex testing, defined as a request for EGFR testing by the pathologist at the time of a nonsquamous nsclc diagnosis. We evaluated the impact of reflex testing on EGFR testing rates. METHODS: A retrospective observational review of the Web-based AstraZeneca Canada EGFR Database from 1 April 2010 to 31 March 2014 found centres within Ontario that had requested EGFR testing through the database and that had implemented reflex testing (with at least 2 years' worth of data, including the pre- and post-implementation period). RESULTS: The 7 included centres had requested EGFR tests for 2214 patients. The proportion of pathologists requesting EGFR tests increased after implementation of reflex testing (53% vs. 4%); conversely, the proportion of medical oncologists requesting tests decreased (46% vs. 95%, p < 0.001). After implementation of reflex testing, the mean number of patients having EGFR testing per centre per month increased significantly [12.6 vs. 4.9 (range: 4.5-14.9), p < 0.001]. Before reflex testing, EGFR testing rates showed a significant monthly increase over time (1.37 more tests per month; 95% confidence interval: 1.19 to 1.55 tests; p < 0.001). That trend could not account for the observed increase with reflex testing, because an immediate increase in EGFR test requests was observed with the introduction of reflex testing (p = 0.003), and the overall trend was sustained throughout the post-reflex testing period (p < 0.001). CONCLUSIONS: Reflex EGFR testing for patients with nonsquamous nsclc was successfully implemented at multiple centres and was associated with an increase in EGFR testing.
