Abstract: A system for predicting therapy resistance and its molecular mechanisms in rectal cancer before treatment is provided. The system includes a feature extraction device, a collection device, a signature construction device and a prediction device. The system can predict responses to neoadjuvant therapy in patients before treatment, analyze patients who are resistant to rectal cancer therapy and their underlying molecular mechanism, thereby enabling personalized therapy for patients who are resistant to rectal cancer therapy. The system has important clinical significance in improving the overall survival of rectal cancer patients.

Abstract: A computer-implemented method includes identifying one or more database modification statements and identifying one or more operational unit indicators. The one or more operation unit indicators are caused to be generated by the one or more database modification statements. An anticipated operational size is determined. The anticipated operational size is an estimated total number of the one or more operational unit indicators. An anticipated operational throughput rate is determined. The anticipated operational throughput rate is a rate at which the operational unit indicators are expected to be generated. An anticipated total execution time of the one or more database modification statements is determined based on the anticipated operational size and the anticipated operational throughput rate. A corresponding computer program product and computer system are also disclosed.
