Abstract
PDF - Background
Although primary cancer of the fallopian tubes is a relatively rare type of tumor in female reproductive organs, its mortality is quite high. It is important to identify molecular and biological markers of this malignancy that determine its specific phenotype.
Methods
The study was carried out on samples received from 71 female patients with primary cancer of the fallopian tubes. The main molecular and biological properties, including hormone status (estrogen receptor [ER], progesterone receptor [PR]), human epidermal growth factor receptor (HER2)/neu expression, proliferative potential (Ki-67), apoptosis (p53, Bcl-2), and pro-angiogenic (vascular endothelial growth factor) quality of serous tumors were studied in comparison with clinical and morphological characteristics.
Results
ER and PR expression is accompanied by low grade neoplasia, early clinical disease stage, and absence of lymphogenic metastasis (p < .001). HER2/neu expression is not typical for primary cancer of the fallopian tubes. Ki-67 expression is characterized by an inverse correlation with ER and PR (p < .05) and is associated with lymphogenic metastasis (p < .01). p53+ status correlates with high grade malignancy, tumor progression, metastasis, negative ER/PR (p < .001), and negative Bcl-2 status (p < .05). Positive Bcl-2 status is positively correlated with ER and PR expression and low grade malignancy.
Conclusions
Complex morphologic (histological and immunohistochemical) study of postoperative material allows estimation of the degree of malignancy and tumor spread to enable appropriate treatment for each case. -

Abstract
PDF
- BACKGROUND
Gefitinib is an EGFR tyrosine kinase inhibitor that has shown dramatic effectiveness in a subset of non-small cell lung cancer (NSCLC) patients. We evaluated the response rate to gefitinib, and the significance of the EGFR and HER2/neu status as predictive markers of the tumor response.
METHODS
The EGFR and HER2/neu protein expressions, as determined by immunohistochemistry (IHC) and gene amplification via chromogenic in situ hybridization (CISH), were analyzed in biopsy specimens from 46 patients with advanced NSCLC. After their failure with the first-line treatment, all the patients had received gefitinib treatment.
RESULTS
A partial response (PR) was achieved in 8 patients (17.4%). An EGFR overexpression was detected in 80.4% (37/46) of the tumors, and this was observed exclusively in patients with a PR (100% vs 75.3%, respectively; p=0.076). EGFR gene amplification was present in 47.8% of the tumors (22/46). HER2/neu was overexpressed in 13%(6/46) and it was amplified in 17% (7/46). The overall survival was prolonged in the female patients (p=0.007), and in patients with T1 and T2 disease (p=0.039), adenocarcinoma (p=0.010), a PR (p=0.022), an EGFR IHC+ status (p=0.033), an EGFR IHC+/CISH+ status (p=0.010), or an EGFR+/HER2/neu+ status (p=0.030). On multivariate analysis, gender, T disease and EGFR IHC/CISH remained the significant predictors of survival.
CONCLUSIONS
Gefitinib showed a modest effect for the patients with chemotherapy-refractory advanced NSCLC. A combination of EGFR IHC and CISH might be important for identifying those patients who are most likely to benefit from gefitinib therapy.
