TL;DR: This study suggests that IR-PSA is an independent favorable prognostic marker for breast cancer and may be used to identify a subgroup of estrogen receptor-negative and/or node-positive patients who have good prognoses.
Journal ArticleDOI
Prostate‐Specific antigen expression by various tumors
TL;DR: It is concluded that in addition to breast tumors and normal breast, colon, ovarian, liver, kidney, adrenal, and parotid tumors can also produce PSA.
Journal ArticleDOI
Mutant p53 protein overexpression is associated with poor outcome in patients with well or moderately differentiated ovarian carcinoma
Michael A. Levesque,Dionyssios Katsaros,He Yu,Paolo Zola,Piero Sismondi,Giorgio Giardina,Eleftherios P. Diamandis +6 more
TL;DR: It is shown that the p53 gene is mutated in 30‐80% of ovarian carcinomas and that the genetic alterations most often manifest as an accumulation of mutant p53 protein in tumor tissue.
Journal ArticleDOI
Prostate specific antigen in breast cancer, benign breast disease and normal breast tissue
He Yu,Eleftherios P. Diamandis,Michael A. Levesque,Maurizia Giai,R. Roagna,Riccardo Ponzone,Piero Sismondi,Maria Monne,Carlo M. Croce +8 more
TL;DR: Examining quantitatively the PSA levels in 199 breast tumors, 48 tissues with benign breast disease, and 36 normal breast tissues suggests that PSA is expressed frequently by normal breast tissue, by tissue of benign breast diseases, and by breast cancer tissue.
Journal Article
Prognostic value of prostate-specific antigen for women with breast cancer: a large United States cohort study.
TL;DR: The results suggest that the measurement of PSA in breast tumor extracts provides additional information on the prognosis of patients with primary breast cancer.
