Notes
**Note 1:** For this schema, code all lymph node (regional and distant) involvement in regional lymph nodes (N). Only visceral and bone marrow involvement are coded in M (distant metastasis). * Peripheral blood involvement is coded in **Site-Specific Factor 1, Peripheral Blood Involvement** **Note 2:** Visceral involvement is metastatic and needs to be questioned in the absence of node or blood involvement. **Note 3:** For visceral disease (Stage IVB), documentation of involvement by only one organ outside the skin, nodes, or blood is needed. **Note 4:** Visceral involvement must be pathologically confirmed, except for the liver and spleen, which may be documented with only imaging.NAACCR Item
