Quantitative immunoprofiles of breast cancer performed by image analysis.
1999
OBJECTIVE: To determine the biopathologic profiles of breast cancer for greater knowledge of tumor natural history and clinical outcome. STUDY DESIGN: In 99 in situ (ISC) and 2718 infiltrating breast carcinomas (IC), biologic markers (estrogen receptor [ER], progesterone receptor [PR] proliferation index, cerbB-2/NEU, p53, bcl-2 and DNA ploidy) were evaluated with an image analysis system (CAS 200/486). In 105 mixed invasive cancers with size 2 cm). In multivariate analysis, PI and NEU in node-negative patients, and NEU, PR and size in node-positive ones emerged as prognostic parameters. CONCLUSION: The results underline the importance of the quantitative biologic profile for defining tumor behavior and patient management.
