Background/aim: It is possible that the degree of enhancement on contrast-enhanced spectral mammography (CESM), a new diagnostic method, might provide prognostic information for breast cancer patients. Therefore, in a group of 82 breast cancer patients, we analyzed the prognostic significance of degree and pattern of enhancement on CESM as well as its relation to: (a) breast cancer immunophenotype (based on ER/PR/HER2 status) (b) podoplanin expression in cancer stroma (lymphatic vessel density plus podoplanin-positivity of cancer-associated fibroblasts), and (c) other histological parameters., Materials and Methods: For each tumor the intensity of enhancement on CESM was qualitatively assessed as strong or weak/medium, while the pattern - as homogenous and heterogenous., Results: Herein we report, for the first time, that strong and heterogenous enhancement on CESM was related to unfavorable disease-free survival of breast cancer patients (p=0.005). Moreover, the strong enhancement was more frequent in large and node-positive tumors (pT>1, pN>0) (p=0.002), as well as in carcinomas with podoplanin-sparse stroma (p=0.008)., Conclusion: Intensity and pattern of enhancement on CESM might provide (together with the results of other diagnostic imaging methods) not only the confirmation of presence or absence of tumor, but also prognostic information., (Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

Background: The aim of the present study was to compare the diagnostic utility of HE4 with NSE, ProGRP, CYFRA 21-1, CEA, and CA 125 and evaluate their prognostic value in patients with small-cell lung cancer (SCLC)., Methods: HE4, ProGRP, NSE, CYFRA 21-1, CEA, and CA 125 assays were performed in 63 patients with smallcell lung cancer (limited disease (LD) - 41, extensive disease (ED) - 22) and in 66 individuals of the reference group., Results: Area under the ROC curves for HE4, ProGRP, NSE, CA 125, CYFRA 21-1, and CEA were 0.884, 0.923, 0.826, 0.796, 0.739, and 0.704, respectively. The tumor marker serum concentrations were associated with tumor stage (HE4, ProGRP, NSE, CYFRA 21-1, CEA), and disease progression occurred within one year (HE4, ProGRP, NSE, CYFRA 21-1). The tumor advancement, performance status, gender and tumor markers, except CEA and CA 125, were significantly associated with survival. Independent, unfavourable prognostic factors included extensive disease (HR 4.14, p < 0.0001) and NSE concentration above 35 g/l (HR 2.62, p = 0.0009)., Conclusions: Diagnostic utility of HE4 was similar to that of NSE and ProGRP. Complementary to NSE, determination of HE4 seems to be helpful in evaluation of SCLC patients' prognosis.

Male breast cancer is a rare form of carcinoma with an incidence rate of approximately 0.5-1% compared with cases of breast carcinoma as a whole. Male breast cancer reacts effectively to endocrine therapy because of a high frequency of hormone receptor expression.The aim of the present study was the assessment of correlations between stage, grade, expression of steroid receptors, basal/mesenchymal markers and proliferation index, as well as analysis of the impact of the above-mentioned parameters on overall (OS) and disease-free survival (DFS) in the group of 32 male breast cancer patients, treated at the Centre of Oncology in Cracow.We showed the significant positive correlation between MIB-1 LI and tumor stage, and hormone receptors (ER or PgR) immunonegativity, and expression of EGFR, vimentin (p<0.05) and P-cadherin (the last at statistical border). The presence of any of basal or masenchymal markers correlated with a more advanced tumor stage. Moreover tumors without vimentin expression were characterised by lower MIB-1 LI and were more frequently EGFR immunonegative.We found that hormone receptor negativity, vimentin immunopositivity and high MIB-1 LI are significant independent indicators of poor OS and DFS for male breast cancer patients (p<0.05).
