Drawing-type scale device for esophageal squamous carcinoma TNM staging

Abstract

The invention provides a pull-out scale device for international TNM staging of esophageal squamous cell carcinoma, which is composed of a rectangular hollow sleeve with openings at both ends and a pumping plate marked with staging results. The pumping plate is inserted into the hollow sleeve. The cover is suitable, and there are a first rectangular window and a second rectangular window on the front of the hollow cover, and a semicircular notch is provided in the middle of the two ends of the opening of the central control cover to facilitate the movement of the pumping plate. On the back and front of the hollow sleeve, relevant definitions of each staging variable are printed. The present invention is displayed in the form of an intuitive ruler, helps clinicians to accurately and quickly stage, and is conducive to remembering new stage regulations as soon as possible. Adjuvant treatment is recommended as early as possible for patients with late stage, and the most appropriate comprehensive treatment plan should be selected. At the same time, strengthen postoperative follow-up monitoring, timely detection of local and distant metastasis, and prolong survival. And it is convenient to make a better treatment plan in the follow-up, and form an objective index that is helpful to effectively evaluate the curative effect.

Description

technical field [0001] The invention belongs to the field of medical clinical application, and relates to a device for international TNM staging of esophageal squamous cell carcinoma. By using the latest version of the American Joint Committee on Cancer (AJCC) TNM staging of esophageal squamous cell The staging method is arranged in the routine order of postoperative pathology, and the staging results are expressed in the form of an intuitive scale, which provides simple and direct clinical application. Background technique [0002] Esophageal cancer is the fifth most common tumor in China and the fourth cause of death, seriously endangering the health of Chinese people. According to statistics, in 2008, there were 2.59 million new cases of esophageal cancer and 2.11 million deaths nationwide. It accounts for more than half of the new cases and deaths of esophageal cancer worldwide. Despite the continuous improvement of surgical techniques and medical equipment, the progno...

Problems solved by technology

[0007] Since the TNM staging system is a system that keeps pace with the times and is sometimes updated at a faster rate and with a larger range, for example, the TNM staging of esophageal cancer in the sixth edition has changed greatly compared with the seventh edition, which causes clinicians Increased difficulty in learning and memorizing TNM staging with tumor registrants

[0008] Clinically, the vast majority of doctors cannot remember the TNM staging accurately and completely, or only remember the old version of the staging, and the follow-up treatment cannot keep up with the new evidence-based medical evidence, which does not meet the requirements of the continuous development of medicine

Look for the NCCN guide every time you encounter staging. Since the current staging system is arranged according to the sub-categories from the staging results to the sub-stages, it is relatively time-consuming

There are also some doctors who simply don’t divide the patients and discharge the patients in a bewildered manner. Further treatment is simply not mentioned, which delays treatment, affects survival, and makes it impossible to evaluate the curative effect.
