* T-cell lymphoma/leukemia IRs after B-cell lymphoma/leukemia and SIRs were not calculated when there were <3 observed cases. Wide confidence bounds emphasize the instability of incidence rate estimates based on small numbers of cases after B-cell lymphoma/leukemia. Data (released April 2023, based on the November 2022 submission) were derived from the MP-SIR session of SEER*Stat software (version 8.4.3) and are available at
www.seer.cancer.gov/seerstat. Abbreviations: precursor acute lymphoblastic leukemia/lymphoma (ALL), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), diffuse large B-cell lymphoma (DLBCL), mycosis fungoides/Sézary syndrome (MF/SS), peripheral T-cell lymphoma (PTCL), 17 cancer registry areas of the Surveillance, Epidemiology, and End Results Program (SEER-17).
