ABSTRACT

Background:

Expression of human paracrine hormones stanniocalcin 1 (STC1) and stanniocalcin 2 (STC2) may potentiate late breast cancer recurrence. We tested the hypothesis that expression of STC1 and STC2 in primary breast tumors is more strongly associated with late versus early recurrences.

Methods:

A total of 541 estrogen receptor-positive, tamoxifen-treated (ER+/TAM+) and 300 ER-negative, tamoxifen-untreated (ER-/TAM-) breast cancer patients who experienced recurrence within 10 years of primary diagnosis and matched recurrence-free controls were selected from a cohort of 11,251 Danish breast cancer patients diagnosed with stage I, II, or III breast cancer during 1985 to 2001. The association between IHC expression of STC1 and STC2 in primary breast tumor tissue microarrays and breast cancer recurrence was evaluated within median time to recurrence quintiles.

Results:

The association between STC1 expression, dichotomized as positive or negative, and recurrence was strongly positive for the final time quintile (6-10 years postdiagnosis) in the ER+/TAM+ group [aOR = 2.70; 95% confidence interval (CI) 1.22-5.98]. Regression of the log ORs relating dichotomous STC1 and STC2 expression to recurrence by median time to recurrence (year) resulted in a relatively large positive effect estimate for STC1 (ß = 0.16; 95% CI, -0.03-0.36) and a near-null positive effect estimate for STC2 (ß = 0.04; 95% CI, -0.14-0.21).

Conclusions:

Our results suggest a stronger association between primary tumor STC1 expression and late recurrence, as opposed to early recurrence, although no clear trend was apparent.Impact STC1 expression in the primary tumor may potentiate late recurrences, suggesting dormancy pathways that merit further investigation.
