The American Joint Committee on Cancer: the 7th Edition of the AJCC Cancer Staging Manual and the Future of TNM. Article (PDF Available). PDF | Department ofSurgery, Thoracic Service, Memorial Sloan-Kettering Cancer Center, New York, NYIn previous editions of the American. Publication of the 7th edition of the AJCC Cancer Staging Manual comes at a major watershed for cancer staging and the AJCC. First, the revolution in under-.
The 7th edition extends the use of nonanatomic factors in cancer staging where supported by clear evidence.
In addition, the 7th edition of the AJCC Cancer Staging Manual provides new tools for recording and using stage in the medical record and the cancer registry, to support electronic capture of these data, and to foster the integration of other prognostic and response predictive factors with stage.
The AJCC is also working closely with the cancer surveillance community and specialty organizations to define and implement clinical instruments that collect data in the format needed to transmit stage, store, and use stage and prognostic data.
Beginning in , the AJCC and its cancer surveillance partners implemented a data collection tool across all US hospital and population registries for cancer stage information, called the Collaborative Stage Data Collection System CS.
This data collection and storage tool may be expanded in the future to incorporate new factors relevant to cancer prognosis. It is also designed for an interoperable electronic environment to allow use of the CS primary staging elements and the CS-derived TNM cancer stage in other electronic platforms.
The CS system is currently being implemented in Canada, and organizations in other nations have inquired about adoption of this tool. Looking to the future, the AJCC is also working with leaders in the epidemiology and statistical modeling scientific communities to foster the use of prognostic and predictive models in clinical oncology.
With an increasing plethora of prognostic tools available on the Internet, the AJCC will provide the key leadership to help developers and users to coordinate use of existing models.
More importantly, the AJCC will provide the leadership to coordinate and sponsor development of new prognostic and predictive models, a process already underway under the leadership of the current AJCC chair, Carolyn Compton.
This is critical to maintain a single, worldwide system for recording and communicating cancer stage. This is particularly important, as cancer becomes one of the leading causes of death around the world.
T3 tumors also include those extending into the gastrocolic or gastrohepatic ligaments, or into the greater or lesser omentum, without perforation of the visceral peritoneum covering these structures.
Tumor invades adjacent structures such as spleen, transverse colon, liver, diaphragm, pancreas, abdominal wall, adrenal gland, kidney, small intestine, and retroperitoneum. Observed survival rates for To be clinically useful, a gastric cancer staging system must meet needs of diverse user groups and accommodate staging of both proximal and distal cancers, which may be biologically different entities. Providing clear rules for staging proximal gastric cancers that cross the esophagogastric junction with the esophageal carcinoma staging system has eliminated the potential for assigning different stages to tumors based on location.
Implementation of these new staging rules also will improve data collection, which will provide the basis for further refinements in TNM staging for these sites.
Future prognostic systems, such as the nomogram systems described by Kattan and colleagues, may allow further refinements in prediction tools, but will not obviate the need for careful assessment of anatomic extent of disease.

Key features and changes to the recommendations to the TNM gastric cancer staging system for the 7th edition include the following: T4 is now defined as a tumor that invades the serosal visceral peritoneum or adjacent structures.
T3 tumors also include those extending into the gastrocolic or gastrohepatic ligaments, or into the greater or lesser omentum, without perforation of the visceral peritoneum covering these structures T4 Tumor invades serosa visceral peritoneum or adjacent structures T4a Tumor invades serosa visceral peritoneum T4b Tumor invades adjacent structures such as spleen, transverse colon, liver, diaphragm, pancreas, abdominal wall, adrenal gland, kidney, small intestine, and retroperitoneum.
The T1 category has been subdivided into T1a invasion of lamina propria or muscularis mucosae and T1b invasion of submucosa to facilitate data collection efforts. Because gastric carcinoma, unlike colorectal carcinoma, may have associated lymph node metastases when tumor is still confined to the lamina propria, invasion of the lamina propria or muscularis mucosae is classified as T1a instead of carcinoma in situ Tis. These have been designated N0 cancers. For adenocarcinoma, the distinction of G1 and G2 none , N1 1—2 , N2 3—6 , and N3 C7 and are identical well and moderately differentiated from G3 poorly dif- to gastric N classifications.
