TNM Classification of malignant tumors 7th edition

TNM Classification of Malignant Tumours, 7th Edition provides the latest, internationally agreed-upon standards to describe and categorize cancer stages and progression. Published in affiliation with the International Union Against Cancer (UICC), this authoritative guide contains important updated organ-specific classifications that oncologists and other professionals who manage patients with cancer need to accurately classify tumours for staging, prognosis and treatment.
The major alterations addressed in the 7th Edition concern carcinomas of the oesophagus and the gastroesophageal junction, stomach, lung, appendix, biliary tract, skin, and prostate. In addition, there are several entirely new classifications:

gastrointestinal carcinoids (neuroendocrine tumours)
gastrointestinal stromal tumour
upper aerodigestive mucosal melanoma
Merkel cell carcinoma
uterine sarcomas
intrahepatic cholangiocarcinoma
adrenal cortical carcinoma.
A new approach has also been adopted to separate anatomical stage groupings from prognostic groupings in which other prognostic factors are added to T, N, and M categories. These new prognostic groupings, as well as the traditional anatomical groupings, are presented for oesophageal and prostate carcinomas.
