Molecular subtype approximated by quantitative estrogen receptor, progesterone receptor and Her2 can predict the prognosis of breast cancer.
Tumori. 2010 Jan-Feb; 96(1):103-10.T

Abstract

AIMS AND BACKGROUND

To investigate the clinicopathological characteristics and prognosis of breast cancer subtypes classified by quantitative estrogen receptor (ER), progesterone receptor (PR), and Her2.

METHODS AND STUDY DESIGN

923 patients with primary breast cancer having a median age of 53 years who were treated at the Cancer Hospital of Fudan University in Shanghai between January 2002 and June 2004 were retrospectively analyzed. Four molecular subtypes were constructed from the immunohistochemical results of quantitative hormone receptor (HR) and Her2 status. HR+ was defined as ER+ and PR+, HR+/- as ER/PR+ at lower levels or lacking either ER or PR, and HR- as both ER- and PR-. The four subtypes were HR+/Her2-, HR+/-/Her2-, HR-/Her2- (triple-negative), and Her2+. Clinical and pathological parameters, disease-free survival (DFS), and overall survival (OS) measurements were compared between patients with different molecular subtypes.

RESULTS

The proportions of HR+/Her2-, HR+/-/Her2-, triple-negative, and Her2+ breast cancer were 36.6% (338/923), 22.9% (211/923), 20.6% (190/923), and 19.9% (194/923). The median follow-up was 49.0 months (4-77 months). In 145 cases disease recurrence or death occurred. In multivariate analysis with the HR+/Her2- subtype taken as the reference category, triple-negative and Her2+ subtypes were associated with increased recurrence and death with a hazard ratio (HR) of 2.05 (95% CI 1.31-3.20; P = 0.002) and 1.89 (95% CI 1.20-2.97, P = 0.006) for DFS and 2.84 (95% CI 1.45-5.55; P = 0.002) and 2.95 (95% CI 1.51-5.77, P = 0.002) for OS, respectively; the HR+/-/Her2- subtype was marginally associated with poor prognosis with HR 1.51 (95% CI 0.94-2.43; P = 0.088) and 1.90 (95% CI 0.92-3.94; P = 0.084) for DFS and OS, respectively.

CONCLUSIONS

Breast cancer subtypes based on quantitative ER, PR, and Her2 may be predictive of prognosis. Patients whose tumors were not HR+/Her2- had a worse outcome in our study.
