Evidence that treating MRD can increase the rates of cure.

Similarly, for hematologic cancers such as acute leukaemias or aggressive lymphomas, a single cycle of intensive chemotherapy can induce CR, but virtually no patients are cured without additional therapy to eradicate MRD.

What does residual cancer burden mean?

Residual cancer burden (RCB) is estimated from routine pathologic sections of the primary breast tumor site and the regional lymph nodes after the completion of neoadjuvant therapy. Six variables are included in a calculation formula. The calculated RCB index value can also be categorized as one of four RCB classes.

What does RCB 3 mean?

RCB index was classified as: RCB-I (minimal burden), RCB-II (moderate burden) or RCB-III (extensive burden). Symmans and colleagues evaluated associations between the continuous RCB index and both event-free survival (EFS) and distant recurrence-free survival (DRFS), adjusting for differences between studies.

What is residual breast cancer?
