Stage 2 rectal cancer is further broken down into symptom groups 2a, 2b, and 2c. In stage 2a, cancerous cells have spread into the outermost rectum wall layer (serosa).3At this point in the cancer's progression, there is no spread outside of the rectum wall. Stage 2b Stage 2b TNM:...
There are several ways to stage rectal cancer; Duke's classification (the first system to stage rectal cancers), Stage system I-IV, and the TNM classification (TNM represents T, the location of the tumor; N, the nodes [lymph nodes] invaded by tumor cells, and M, metastasisof tumor cells...

We analysed 1005 rectal cancer cases diagnosed between 1982 and 1987 and followed up for at least 5 years. In the Mallorca registry, 16% of the patients were diagnosed in the TNM stage I (versus 21% in the Côte d'Or registry and 29% in the Geneva registry, P < 10–4) and the ...
Moreover, many randomized trials have clearly demonstrated that neoadjuvant therapy followed by surgery is superior to radical surgery alone and to postoperative chemoradiotherapy for locally advanced rectal cancer (TNM stage II鈥揑II) [2, 3]. With this approach, the 5-year local recurrence (LR) ...
The postoperative pathology TNM stage was used to differentiate locally advanced rectal cancer (T3/4 or N1/2) from locally early rectal cancer (T1/2, N0). Logistic regression was used to construct separate prediction models for T stage and N stage. The models' predictive performance was ...
Therefore, the clinical diagnosis was rectal cancer cT3N0M0, cStage IIa (UICC TNM classification 8th edition) [10]. Fig. 1 Preoperative colonoscopy. A Initial colonoscopy shows a rectal tumor below the peritoneal reflection 5 cm from the anal verge, occupying three quarters of the circumference...
