  • NOTE: Cumulative 7-year RR for stage II breast cancer patients adjusted for year and age of diagnosis.

  • * Model adjusted for year of (1992-1995, 1996-1999, 2000-2002) and age at diagnosis (40-49, 50-59, 60-69 years).

  • Stage not definable because lymph nodal involvement was not noted (92%) or information on tumor size was missing.
