Drawing-type scale device for esophageal squamous carcinoma TNM staging

Abstract

The invention provides a drawing-type scale device for esophageal squamous carcinoma TNM staging. The drawing-type scale device comprises a rectangular hollow sleeve with two ends open and a drawing plate marked with staging results. The drawing plate is inserted into the hollow sleeve and fits with the same in length. A first rectangular window and a second rectangular window are formed in the front of the hollow sleeve. A semicircular notch is formed in the middle of each open end of the hollow sleeve for the convenience of moving the drawing plate. The back and the front of the hollow sleeve are printed with related definitions of all staging variables. Due to displaying in a visual scale form, clinicians are helped to accurately and rapidly stage, and beneficially remember new staging regulations as soon as possible. For patients in later staging, early postoperative adjuvant treatment is suggested, and an optimal comprehensive treatment scheme is selected. Meanwhile, postoperative follow-up monitoring is enhanced to discover local and distant metastasis in time so as to prolong survival. Besides, convenience is brought to make better treatment schemes subsequently to form objective indicators in favor of effectively evaluating 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.
