Extranodal lymphomas
Aggressive lymphomas
•
Same principles as for nodal lymphomas
•
In many organs (e.g., stomach, salivary
glands, thyroid gland, CNS) lymphoma is
multifocal. Hence, the whole organ is
treated even if apparently only partially
involved
•
Even with modern imaging it may be
difficult to accurately define the exact
extent of disease in many extranodal sites.
Hence, the whole organ is treated even if
apparently only partially involved
Indolent lymphomas
•
Same principles as for nodal lymphomas
•
Whole organ is usually treated even if
apparently only partially involved (for
the same reasons as for aggressive
lymphomas)
•
Uninvolved nodes are not routinely
included in the CTV. First echelon nodes
of uncertain status close to the primary
organ may be included
