Female breast cancer was more likely diagnosed between 1 to 5 years than within the first year of diagnosis of a BPRU cancer, and the relative risk for lung cancer diagnosis remained elevated up to 5 to 10 years from the original primary diagnosis.
2 show the accumulation of second primaries among patients previously diagnosed with a BPRU cancer using competing risk analysis.
The overall risk for diagnosis of a second primary cancer is greatest for males within the first year of being diagnosed with a BPRU cancer and persists for up to 5 years; beyond 10 years there is no significant elevation in risk compared with a standardized matched population.
g, in 2003, 7 patients diagnosed BPRU cancer had a maximum 5-year follow-up).
