Article Synopsis
- Strategies to minimize COVID-19’s impact led to a significant reduction in diagnostic testing for breast, cervical, and colorectal cancers in Manitoba, Canada.
- A population-based study tracked these diagnostic rates from January 2015 to August 2022, revealing dramatic decreases in various tests following the pandemic's onset, such as a 77% drop in bilateral mammograms.
- As of late 2022, the data indicated lingering deficits in diagnostic tests, with thousands fewer tests conducted compared to pre-pandemic expectations, highlighting ongoing impacts on cancer care.
Background: Breast-conserving therapy is the standard of care for ductal carcinoma in situ (DCIS). Debate on what constitutes a satisfactory margin persists. This study aimed to identify predictors of residual disease at re-excision.

Methods: This population-based study used data from Norway, the four UK nations (England, Northern Ireland, Scotland, and Wales), nine Canadian provinces (Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island, and Saskatchewan), and two Australian states (New South Wales and Victoria).
Background: There are few data on international variation in chemotherapy use, despite it being a key treatment type for some patients with cancer. Here, we aimed to examine the presence and size of such variation.
Methods: This population-based study used data from Norway, the four UK nations (England, Northern Ireland, Scotland, and Wales), eight Canadian provinces (Alberta, British Columbia, Manitoba, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island, and Saskatchewan), and two Australian states (New South Wales and Victoria).
Background: Few studies have investigated the impact of the COVID-19 pandemic on cancer survival. Those studies that have included pandemic vs prepandemic comparisons can mask differences during different periods of the pandemic such as COVID-19 waves. The objective of this study was to investigate the impact of the COVID-19 pandemic on cancer survival using an interrupted time series analysis and to identify time points during the pandemic when observed survival deviated from expected survival.
