Abstract
Objective We aimed to investigate the correlation of the perfusion parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) with the molecular biological expression of breast infiltrating ductal carcinoma (IDC) in order to guide appropriate therapeutic advice and clinical outcome prediction. Materials and Methods In a prospective analysis of 67 patients with breast IDC, preoperative DCE-MRI and routine MRI images were obtained. The double-chamber model (extended Tofts model) was employed to calculate the perfusion parameters. Postoperative pathological immunohistochemistry was examined, including human epidermal growth factor receptor 2 (HER-2), estrogen receptor (ER), progesterone receptor (PR), cell nuclear-associated antigen (Ki-67), cytokeratin 5/6 (CK5/6), and epidermal growth factor receptor (EGFR). Statistical analysis was applied to explore the relationship between the perfusion parameters and the molecular biomarkers of breast cancer. Results A total of 67 lesions were included in our study. The mean maximum diameter of lesions was 4.48 ± 1.73 cm. Perfusion parameters had no correlation with tumor diameters (p > 0.05). The volume transfer constant (K trans) and the rate constant (k ep) had positive correlations with Ki-67 (p < 0.05). The plasma volume ratio (v p) had a statistical difference between CK5/6 positivity and CK5/6 negativity. The maximum rising slope (MAX Slope) was higher in HER-2-enriched tumors than that in luminal A or B tumors (p < 0.05). k ep was higher in HER-2-enriched tumors than that in luminal A tumors (p < 0.05). The extravascular extracellular space volume fraction (v e) was higher in triple-negative tumors than that in HER-2-enriched and in luminal A and B tumors (p < 0.05). The time to peak enhancement (TTP) was lower in HER-2-enriched tumors than that in luminal A and B tumors (p < 0.05). Maximum concentration (MAX Conc) was higher in triple-negative tumors than that in luminal B tumors (p < 0.05). Conclusion DCE-MRI perfusion parameters can behave as a noninvasive tool to assess the molecular biological expression and the molecular subtypes of breast IDC. They may aid in predicting breast IDC invasiveness, metastasis, and prognosis.

Abstract
BACKGROUND Fine needle aspiration (FNA) is a quick, minimally invasive procedure for evaluation of breast tumors. The Scarff-Bloom-Richardson (SBR) grade on histological sections is a well-established tool to guide selection of adjuvant systemic therapy. Grade evaluation is possible on cytology smears to avoid and minimize the morbidity associated with overtreatment of lower grade tumors. AIM The aim was to test the hypothesis whether breast FNA from the peripheral portion of the lesion is representative of Scarff-Bloom-Richardson grade on histopathology as compared to FNA from the central portion. MATERIALS AND METHODS Fine-needle aspirates and subsequent tissue specimens from 45 women with ductal carcinoma (not otherwise specified) were studied. FNAs were performed under ultrasound guidance from the central as well as the peripheral third of the lesion for each case avoiding areas of necrosis/calcification. The SBR grading was compared on alcohol fixed aspirates and tissue sections for each case. RESULTS Comparative analysis of SBR grade on aspirates from the peripheral portion and histopathology by the Pearson chi-square test (χ(2) =78.00) showed that it was statistically significant (P<0.001) with 93% concordance. Lower mitotic score on aspirates from the peripheral portion was observed in only 4 out of 45 (9%) cases. The results of the Pearson chi-square test (χ(2) = 75.824) with statistically significant (P=0.000). CONCLUSION This prospective study shows that FNA smears from the peripheral portion of the lesion are representative of the grading performed on the corresponding histopathological sections. It is possible to score and grade by SBR system on FNA smears.

Abstract
OBJECTIVE To study the possible associations between preoperative serum CEA and CA15.3 levels and different clinical-biological parameters of infiltrating ductal carcinomas of the breast (IDC). PATIENTS AND METHOD Preoperative serum CA15.3 and CEA levels were determined in 255 and 224 females, respectively, having IDC. We assayed the cytosolic levels of estrogen receptor, pS2, cathepsin D and hyaluronic acid, as well as the levels of epidermal growth factor receptor in cell surfaces. Tumor size, axillary involvement (N), distant metastasis (M), histological grade (HG) and cellular S-phase (SP) were taken into account. RESULTS 22 IDC were positive for CA15.3 (> 40 U/ml) and they had greater global tumor size (p < 0.001), > 2 cm (p: 0.005) and distant metastasis (p < 0.001). 19 IDC were positive for CEA (> 4 ng/ml) and they had greater global tumor size (p < 0.001), > 2 cm (p < 0.001), > 5 cm (p: 0.052) and global S-phase values (p: 0.062), and were more frequently N + (p: 0.045), > 3N + (p: 0.001) and > 10N + (p < 0.001), M + (p: 0.004), HG3 (p: 0.091) and SP > 7 % (p: 0.006). CONCLUSIONS Our results led us to the following: In patients having IDC of the breast, preoperative serum CA15.3 levels are associated with greater tumor size and distant metastasis, while pre-treatment CEA serum levels are associated moreover with axillary involvement; we have not observed any correlation between serum levels of both antigens and the hormonal status of the tumor; these results had physiopathological interest but reduced clinical value in pretreatment breast carcinomas due to their low sensitivity of both markers. However, they are useful in the follow-up of the patients when assessing serum concentrations of both markers, since they contribute to knowing the patients' clinical status better.

Abstract
OBJECTIVE The trefoil factor 1 (TFF1/pS2) is an estrogen-induced molecule in breast tumours. We wanted to study its expression in ER+ and PgR+ infiltrating ductal carcinomas of the breast (IDCs), and to correlate it with other clinical-biological parameters and the outcome. MATERIAL AND METHODS Cytosolic pS2 levels were measured using an IRMA (CIS. Biointernational. France) in 170 tumors. Likewise we determined the cytosolic levels of cathepsin D and tissue-type plasminogen activator (t-PA), as well as the concentrations of the epidermal growth factor receptor (EGFR), erbB2 oncoprotein, CD44v5 and CD44v6 on cell surfaces. Also the tumour size, histological grade (HG), axillary lymph node involvement, distant metastasis, ploidy, DNA index and of cellular synthesis phase (SP) was taken in account. RESULTS The pS2-positive (> 5 ng/mg prot.) tumours showed higher concentrations of cathepsin D (p: 0.0043) and t-PA (p: 0.0089) than the pS2-negative ones. Likewise, they were less frequently HG3 (p: 0.0231), SP > 7 % (p: 0.0005) and SP > 14% (p:0.0014). During the follow-up time (r: 1-147; 50,1+/-31,7; median 37 months) the pS2-positive tumors showed a less number of recurrences (5/101 vs 6/69; p: 0.059) but not of deaths by the tumor (1/101 vs 2/69). CONCLUSIONS These results support an inverse relationship between pS2 positivity and cellular proliferation in IDCs and suggest a new role of this protein (different of the hormone dependence) in the biology of these breast carcinomas, while further studies will be required to establish the impact of this finding on their outcome.

Abstract
INTRODUCTION CA125 is a useful serum tumor marker in patients with non-mucinous ovarian cancer, but there may be high serum levels in other malignant tumors, among them the non-small cell lung cancers. We decided to study the cytosolic levels of CA125 in lung adenocarcinomas and compare them with pS2, CD44s, CD44v5 and CD44v6, all of them with biological interest in this subtype of lung carcinomas. SUBJECTS AND METHODS The study group included 55 patients (33 males) having lung adenocarcinomas. CA125 and cytostolic pS2 were measured by both IRMAS methods (CIS. Biointernational. France). The concentrations of CD44 standard (CD44s), CD44v5 and CD44v6 on cell surfaces were dosed by EIAS (Bender Diagnostics. Austria). Clinical stage, ploidy and S-phase cellular fraction were also taken into account. RESULTS In the 55 lung adenocarcinomas, cytosolic CA125 levels ranged between 1 and 225 U/mg prot. (median 80.5) and were higher (p:0.002) than those observed in 16 normal lung tissues from the same patients (r: 1-32.5; median 6.7 U/mg prot.). When the 25th (7.2 U/mg prot.) and 75th (320 U/mg prot.) percentiles were used as clinical cut-offs, we found that the cases with high antigenic levels showed a greater positivity for CD44v6 (p:0.002) and a reduced positivity for CD44 standard (p:0.053). Likewise, they showed a tendency towards being pS2 + (p:0.09) more frequently. CONCLUSIONS Our results lead us to draw the following conclusions: 1) Cytosolic CA125 levels in lung adenocarcinomas were higher than those observed in normal tissues from the same patients. 2) Lung adenocarcinomas with high cytosolic CA125 concentrations had a greater positivity for CD44v6, a reduced positivity for CD44s and were more frequently pS2 +. These associations support the usefulness of the cytosolic CA125 levels as an indicator of poor outcome in this subtype of lung carcinomas.

Abstract
BACKGROUND AND OBJECTIVE We decided to study the axillary lymph node invasion (N) in hormone-independent breast cancer. PATIENTS AND METHOD The study group included 77 ER and 47 ER/PgR breast carcinomas. Both ER and PgR were determined using EIAS from Abbott (USA). RESULTS In ER tumors, one the most important finding was the high concentration (p = 0.001) and percentage of positives ( > 50 pmol/mg prot.; 24/41 vs 7/36; p < 0.01) of cathepsin D observed in N+ vs N- tumors. In ER/PgR negative tumors, lymph node involvement was associated with a same behavior of this proteinase (p = 0.021; 17/31 vs 2/16; p = 0.006) exclusively. CONCLUSIONS Our results point to a possible usefulness of cathepsin D in this type of carcinomas.

Abstract
The prognostic value of cathepsin D has been recently recognized, but as many quantitative tumor markers, its clinical use remains unclear partly because of methodological issues in defining cut-off values. Guidelines have been proposed for analyzing quantitative prognostic factors, underlining the need for keeping data continuous, instead of categorizing them. Flexible approaches, parametric and non-parametric, have been proposed in order to improve the knowledge of the functional form relating a continuous factor to the risk. We studied the prognostic value of cathepsin D in a retrospective hospital cohort of 771 patients with breast cancer, and focused our overall survival analysis, based on the Cox regression, on two flexible approaches: smoothing splines and fractional polynomials. We also determined a cut-off value from the maximum likelihood estimate of a threshold model. These different approaches complemented each other for (1) identifying the functional form relating cathepsin D to the risk, and obtaining a cut-off value and (2) optimizing the adjustment for complex covariate like age at diagnosis in the final multivariate Cox model. We found a significant increase in the death rate, reaching 70% with a doubling of the level of cathepsin D, after the threshold of 37.5 pmol mg(-1). The proper prognostic impact of this marker could be confirmed and a methodology providing appropriate ways to use markers in clinical practice was proposed.

Abstract
Geno-phenotypic patterns of pre-invasive and invasive lobular breast cancers and infiltrating ductal carcinomas of low, intermediate, and high grade are reviewed. One of the main differences between lobular breast cancers and ductal carcinomas is the presence of inactivating E-cadherin gene mutations in lobular breast cancers. In many other respects, lobular breast cancers and low-grade ductal carcinomas exhibit similar geno-phenotypic profiles. The development of p53 dysfunction may be a hallmark of infiltrating ductal cancers of intermediate and high grade. Sequential Her-2/neu and ras abnormalities define a subset of aggressive high-grade tumors, and the development of Rb dysfunction may define a separate subset of aggressive ductal cancers. Based on these observations, a branching molecular evolutionary model for the development and progression of breast cancer is proposed.

Abstract
HER-2/Neu overexpression is seen in 20% to 30% of invasive breast carcinomas and has been reported in as many as 80% of high-grade infiltrating carcinomas. Earlier studies have suggested that 100% of the tumor cells in mammary Paget disease show overexpression of HER-2 protein. We undertook this study to assess HER-2 status of mammary Paget disease and of the underlying breast carcinoma, when present, by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). Formalin-fixed, paraffin-embedded tissue from 20 cases of mammary Paget disease were analyzed for HER-2 status by IHC and FISH. IHC for estrogen receptor (ER) was also performed. The patients ranged in age from 34 to 88 years, with a mean age of 62 years. Eighty percent of the cases showed strong overexpression (3+) of HER-2 protein by IHC, and all of these cases showed more than 5-fold amplification of the HER-2 gene by FISH. The remaining 4 cases, which were negative for HER-2/Neu by IHC, showed no amplification by FISH. All of the latter cases expressed ER, whereas no case that overexpressed HER-2 expressed ER. Sixteen cases had an underlying tumor, which was in situ in 6 cases. The underlying tumors were identical to the Paget disease with respect to their HER-2/Neu overexpression by both IHC and FISH. HER-2 overexpression was identified in 80% of our cases of Paget disease. There was 100% concordance between HER-2 protein overexpression by immunohistochemistry and gene amplification in both the Paget and the underlying tumor. Moreover, all of the cases negative for HER-2 overexpression expressed ER, whereas those positive for HER-2 did not.

Abstract
INTRODUCTION pS2 was first identified as an estrogen induced molecule in a breast cancer cell line, but its gene responds to several growth factors and oncogenic proteins. Its main clinical application lies in breast carcinomas, where it is a molecular marker to identify breast cancer patients who will respond to hormone therapy. This study was performed to evaluate the significance of the pS2 cytosolic levels in non small cell lung carcinomas classified according to different clinical and biological parameters. Likewise, the results obtained were correlated with those observed in normal tissues. MATERIAL AND METHODS The study group included 154 non small cell lung carcinomas (59 adenocarcinomas and 95 squamous carcinomas) and 54 normal lung samples. Cathepsin D, pS2, neuron specific enolase (NSE) and CA125 cytosolic concentrations were determined, as well as those of epidermal growth factor receptor (EGFR), erbB2 protein, CD44s, CD44v5 and CD44v6 on cell surface membranes. Likewise, clinical stage, histological grade, ploidy and cellular S-phase fraction were also considered as variables of the study. RESULTS We observed cytosolic pS2 values greater than 1 ng/mg protein (positive cutoff) in 18/59 adenocarcinomas and in 10/95 squamous carcinomas (p:0.00177). In adenocarcinomas, pS2 positivity was not correlated with any clinical and biological parameters, but positive cases had lower EGFR (p:0.03770) concentrations and higher CA125 (p:0.01902) levels. In squamous carcinomas, pS2 positivity was associated with lower EGFR (p:0.02270) levels and higher erbB2 protein (p:0,00563) concentrations. CONCLUSIONS Our results led us to suggest the following: 1) cytosolic pS2 concentrations are higher in tumoral than in normal samples; 2) adenoarcinomas had higher levels than squamous lung carcinomas; 3) in adenocarcinomas, positivity for pS2 is associated with lower EGFR levels and higher CA125 concentrations suggesting a worse outcome, and 4) in squamous lung tumors, positivity for pS2 was associated with lower EGFR and higher erbB2 oncoprotein concentrations, it not being possible to establish its clinical significance, although it may be correlated with a poor prognosis.
