Evaluation of Recurrence Rate in Canadian Patients With Stage II/III HR+/HER2- Breast Cancer Using Real-Life Health Data

Breast cancer is the most common cancer and the second leading cause of cancer-related mortality among Canadian women. The majority of cases fall into the HR+/HER2- subtype, constituting approximately two-thirds of all diagnoses. Treatment for this subtype includes a multifaceted approach with curative intent. This real-life study aims to comprehensively analyze the clinical outcomes of Canadian patients diagnosed with early-stage HR+/HER2- breast cancer, focusing on recurrence rates after initiation of adjuvant endocrine therapy to identify opportunities to improve patient care.

Real-World Safety of Niraparib for Maintenance Treatment of Ovarian Cancer in Canada

Real-World Safety of Niraparib for Maintenance Treatment of Ovarian Cancer in Canada

Niraparib was recently funded in Canada for the maintenance treatment of ovarian cancer following platinum-based chemotherapy. However, the drug’s safety profile in the real world remains uncertain. We conducted a cohort study to describe the patient population using niraparib and the proportion that experienced adverse events between June 2019 and December 2022 in four Canadian provinces (Ontario, Alberta, British Columbia, and Quebec). We used administrative data and electronic medical records from Ontario Health, Alberta Health Services, and BC Cancer, and registry data from Exactis Innovation.

A Phase II Exploratory Study to Identify Biomarkers Predictive of Clinical Response to Regorafenib in Patients with Metastatic Colorectal Cancer Who Have Failed First-Line Therapy

Single-agent regorafenib is approved in Canada for metastatic colorectal cancer (mCRC) patients who have failed previous lines of therapy. Identifying prognostic biomarkers is key to optimizing therapeutic strategies for these patients. In this clinical study (NCT01949194), we evaluated the safety and efficacy of single-agent regorafenib as a second-line therapy for mCRC patients who received it after failing first-line therapy with an oxaliplatin or irinotecan regimen with or without bevacizumab.

Third-line treatment patterns in HER2-positive metastatic breast cancer: a retrospective analysis of real-world data in Canada

There is an increasing demand for real-world data pertaining to the usage of cancer treatments, especially in settings where no standard treatment is specifically recommended. This study presents the first real-world analysis of third-line treatment patterns in HER2-positive metastatic breast cancer (mBC) patients in Canada. The purpose was to assess evolution of clinical practice and identify unmet needs in post-second-line therapy. Retrospective data from medical records of 66 patients who received third-line treatment before 31st October 2018, and data from 56 patients who received third-line treatment after this date, extracted from the Personalize My Treatment (PMT) cancer patient registry, were analyzed.
