“…Sir — We read with interest the letter recently published in Clinical Oncology by de Sousa and collaborators [ 1 ] and congratulate the authors on their work. Although it provided valuable insights into the pandemic's impact on cancer staging in Brazil, we want to highlight the specific impact on neuro-oncology surgical care.…”

PURPOSE The early phase of the COVID-19 pandemic affected cancer care globally. Evaluating the impact of the pandemic on the quality of cancer care delivery is crucial for understanding how changes in care delivery may influence outcomes. Our study compared care delivered during the early phase of the pandemic with the same period in the previous year at two institutions across continents (Princess Margaret Cancer Center [PM] in Canada and A.C. Camargo Cancer Center [AC] in Brazil). METHODS Patients newly diagnosed with colorectal or anal cancer between February and December 2019 and the same period in 2020 were analyzed. Sociodemographic and clinical characteristics and performance of individual indicators within and between centers and between the peri–COVID-19 and control cohorts were tested using Cohen's h test to assess the standardized differences between the two groups. RESULTS Among 925 patients, distinct effects of the early COVID-19 pandemic on oncology services were observed. AC experienced a 50% reduction in patient consultations (98 v 197) versus a 12.5% reduction at PM (294 v 336). Similarly, AC experienced a higher proportion of stage IV disease presentations (42.9% v 29.9%; P = .015) and an increase in treatment delay (61.9% v 9.7%; P < .001) compared with prepandemic. At PM, a 10% increase in treatment interruption (32.4% v 22.3%; P < .001) and a higher rate of discontinuation of radiotherapy (9.4% v 1.1%; P < .001) were observed during the pandemic. Postsurgical readmission rates increased in both AC (20.9% v 2.6%; P < .001) and PM (10.5% v 3.6%; P < .01). CONCLUSION The early phase of the COVID-19 pandemic affected the quality of care delivery for colorectal and anal cancers at both centers. However, the magnitude of this impact was greater in Brazil.
