Importance and strategies of enhancing diagnostic accuracy in clinical staging for gastrointestinal carcinoma
Abstract：Accurate assessment of local tumor depth invasion (T), regional lymph node invasion (N), and distant metastases (M) is crucial to appropriate surgical and treatment planning for gastrointestinal carcinoma. Understaging of the disease may lead to positive resection margins or unnecessary laparotomy if metastases were not identified on preoperative imaging. Overstaging a patient may lead to ineffective care if a potentially curative patient is incorrectly categorized as a palliative patient. National Comprehensive Cancer Network (NCCN) practice guidelines for gastric cancer and colorectal cancer suggest using a variety of techniques as part of the workup, including CT of abdomen, pelvis and chest imaging, endoscopic ultrasound, endorectal ultrasound, MRI, PET-CT and so on. As routine use of each imaging modalities has limitations, combined utilization should be recommended for preoperative assessment.
