The seventh edition of the AJCC Cancer Staging Manual is the most recent standard description of the anatomical presence and virulence of cancer. Cancer registries use staging as structure for their databases. When combined with outcome data, staging can help clinicians assess complete remission, overall survival, progression-free survival, and other responses to treatment. The goal of this book is to provide, through correct and meaningful staging, guidance for devising the most appropriate care plan and for changing the plan in response to new information.
