The purpose of this observational study is to understand the predictive effect of the laboratory-developed TIMES scoring system on the recurrence status of cancer patients who have undergone surgical tumor resection. The main questions it aims to answer are:

Can the TIMES scoring system accurately predict the recurrence status of cancer patients who have undergone surgical tumor resection? What is the accuracy of the TIMES scoring system? The medical records or biological specimens used in this study were obtained from previous clinical treatments, and the tissues used were collected from post-surgical discarded tissues from the participants, which will not affect their health. Researchers will continuously monitor the disease progression of the participants for up to 10 years or until cancer recurrence occurs.

No grouping, the long-term tracking of participants' disease progression and recurrence status will be compared with the analysis results of the collected discarded tumor tissues from the participants' surgeries
