Squamous cell carcinoma uses a TNM system to determine the different stages of this skin cancer. This article breaks down the stages and what it means for you.

This update to Appendix A provides updated information on staging using UICC TNM 8, which should be used for all tumours diagnosed after 1 January 2018.

3 天之前 · T2: Tumor more than 2 cm in greatest dimension with or without one additional high risk features, or any size with two or more high risk features. T3: Tumor with invasion of maxilla, mandible, orbit, or temporal bone.

2024年10月8日 · Esophageal and esophagogastric junction squamous cell carcinoma staging refers to TNM staging of squamous cell carcinoma originating in the esophagus or esophagogastric junction (including tumors whose center …

Although most cSCC is cured with office-based therapy, advanced cSCC poses a significant risk for morbidity, impact on quality of life, and death. This document provides evidence-based recommendations for the management of patients with cSCC.

The system most often used to stage basal and squamous cell skin cancers is the American Joint Commission on Cancer (AJCC) TNM system. The most recent version, effective as of 2018, applies only to squamous and basal cell skin cancers of the head and neck area (lip, ear, face, scalp, and neck).

SCC usually presents as an indurated nodular keratinizing or crusted tumour that may ulcerate, or it may present as an ulcer without evidence of keratinization. All patients in whom there is a possibility of a cSCC should be referred urgently to an appropriately trained specialist who is attached to an LSMDT, usually in their local dermatology ...

For squamous, basal and adnexal carcinomas, but not Merkel cell carcinoma (MCC), the T1-T3 categories are defined by new 20-mm and 40-mm divisions based on the maximum dimension of the lesion. In addition, new risk factors upstage T1 or T2 to T3. For melanoma, mitotic index no longer influences separation of pathological stage (pT1).

In the past, the American Joint Committee on Cancer (AJCC) TNM staging system for non-melanoma skin cancer (NMSC) was primarily based on tumor diameter, and a single staging system was used for all types of NMSC. A previous study assessing the 6 th edition staging system identified key flaws in the earlier system 21.

Accurate staging of a skin cancer is essential in order to properly plan its management. Staging takes account of the tumour itself (T), whether it has spread to lymph glands (nodes – N) and whether it has spread to distant organs (metastases – M). The TNM classification system is constantly being revised in the light of new research.
