ClinConnect Summary

This clinical trial is studying how the COVID-19 pandemic impacted cancer diagnoses in Bavaria, Germany. Researchers are looking at how many cancer cases were diagnosed before and during the pandemic, while considering factors like the age of patients and economic conditions in different areas. The goal is to understand if certain regions or types of cancer, particularly those that usually have regular check-ups, saw a bigger drop in diagnoses due to the pandemic. This information could help healthcare systems better prepare for future health crises and ensure that cancer treatments remain effective even during difficult times.

To participate in this study, individuals must be at least 18 years old and have been diagnosed with any type of cancer in Bavaria from 2018 to 2023. However, cases where the only information comes from death certificates are not included, as they don’t provide enough details about the diagnosis. The trial is not yet recruiting participants, but once it starts, it aims to gather important data that could improve cancer care during emergencies.
