This clinical trial is focused on studying the effects of regular use of aspirin on the recurrence and survival of patients who have undergone primary treatment for common non-metastatic solid tumors. The diseases being studied include breast cancer, colon cancer, rectal cancer, stomach cancer, oesophageal cancer, and prostate cancer. The treatment involves taking aspirin in the form of gastro-resistant tablets, which are designed to dissolve in the intestine rather than the stomach, to help prevent irritation. The study will also use a placebo, which is a tablet that looks like the aspirin tablet but does not contain the active ingredient.
The purpose of the study is to determine if taking aspirin regularly after standard cancer treatment can help prevent the cancer from coming back and improve the chances of survival. Participants in the study will be randomly assigned to receive either the aspirin or the placebo. The study is designed to be double-blind, meaning neither the participants nor the researchers will know who is receiving the aspirin and who is receiving the placebo. This helps ensure that the results are not influenced by expectations or bias.
Participants will take the study medication for a period of up to 60 months. Throughout the study, participants will be monitored for any side effects and for signs of cancer recurrence. The study will also look at other health outcomes, such as overall survival, adherence to the medication, and any serious health events that may occur. The goal is to gather information that could lead to better treatment strategies for preventing cancer recurrence and improving survival rates in patients with these types of cancers.
