Insights

Trefoil factor-1 and -3 (TFF1, TFF3), FOXA1, CA XII, and TRPS1 are sensitive diagnostic markers for breast carcinoma in effusions. FOXA1 showed the highest sensitivity, while TRPS1 was the most specific marker.

Area of Science:

  • Oncology
  • Pathology
  • Biomarker Discovery

Background:

  • Serous effusions are challenging for cancer diagnosis.
  • Identifying reliable diagnostic and prognostic markers for breast carcinoma in effusions is crucial.

Purpose of the Study:

  • To evaluate the diagnostic utility of trefoil factor-1 and -3 (TFF1, TFF3), forkhead box protein A1 (FOXA1), carbonic anhydrase XII (CA XII), and trichorhinophalangeal syndrome type 1 (TRPS1) in serous effusions.
  • To investigate the prognostic role of these markers in breast carcinoma.

Main Methods:

  • Immunohistochemistry was used to analyze protein expression in 247 effusions.
  • The study included various carcinomas (breast, tubo-ovarian, lung, gastrointestinal, etc.) and mesotheliomas.

Main Results:

  • TFF1, TFF3, FOXA1, CA XII, and TRPS1 were expressed in 67%, 70%, 88%, 82%, and 83% of breast carcinomas, respectively.
  • All markers were significantly overexpressed in breast carcinoma compared to tubo-ovarian and lung carcinomas.
  • TFF1, TFF3, and FOXA1 expression was higher in receptor-positive breast carcinomas; TFF1 showed a trend towards longer survival.

Conclusions:

  • TFF1, TFF3, FOXA1, CA XII, and TRPS1 are sensitive markers for breast carcinoma in effusions.
  • FOXA1 demonstrated the highest sensitivity, and TRPS1 exhibited the highest specificity.
  • Further research is needed to confirm the prognostic value of these markers in breast carcinoma effusions.
