The 2007 Toronto study that gave triple-negative breast cancer its clinical portrait: 11 percent of cases, a risk of distant relapse 2.6 times higher than other breast cancers, a peak at three years and then a fall, so that women who reach five years without relapse are largely safe.
Dent, Trudeau, Pritchard, Hanna and colleagues studied 1,601 women diagnosed with breast cancer at Women's College Hospital, Toronto, between 1987 and 1997, with median follow-up of 8.1 years; 180 (11.2 percent) had triple-negative tumours (oestrogen receptor-, progesterone receptor- and HER2-negative). Compared with other breast cancers, triple-negative disease carried an increased likelihood of distant recurrence (hazard ratio 2.6, 95 percent confidence interval 2.0 to 3.5) and death (hazard ratio 3.2, 2.3 to 4.5) within five years of diagnosis but not thereafter; the risk of distant recurrence peaked at about three years and declined rapidly, whereas in other cancers it was constant over follow-up.
Explains why triple-negative trials can use three-year event-free survival, why follow-up is front-loaded, and why survivors past five years are told their risk has largely passed.
