Currently used methods to detect and enumerate circulating tumor cells (CTCs) rely on the expression of the epithelial cell adhesion molecule (EpCAM) and cytokeratins. This selection may exclude cells that have undergone intrinsic modifications of their phenotype, as epithelial-mesenchymal transition (EMT). Aim of the study was to investigate the expression(More)
OBJECTIVE To evaluate the prognostic significance of survivin in tumour tissues and that of survivin-expressing circulating tumour cells (CTCs) in T1G3 bladder tumours, as the prognosis of T1G3 bladder cancer is highly variable and unpredictable from clinical and pathological prognostic factors. PATIENTS AND METHODS The study included 54 patients with(More)
OBJECTIVE/BACKGROUND The GONO-FOLFOXIRI regimen improved the rate of R0 secondary resection of metastases in initially unresectable metastatic colorectal cancer. The objective of this study was to evaluate the long-term outcome of resected patients and the impact of FOLFOXIRI on perioperative morbidities, mortality, and chemotherapy induced hepatotoxicity.(More)
BACKGROUND mTOR inhibitors are currently used in the treatment of solid malignancies. Since their approval, several cases of pulmonary toxicity (PT) have been described. This analysis aims to report the incidence and the risk of PT in published randomized controlled trials. MATERIAL AND METHODS PubMed and Scopus were reviewed for phase II-III randomized(More)
The expression of nitric oxide synthase (NOS) isoforms has been investigated in normal (three subjects) and benign hyperplastic prostate (ten patients) by immunohistochemistry and reverse transcriptase-polymerase chain reaction (RT-PCR). The inducible NOS (iNOS or NOS-2) is not detected in normal prostate, while it is expressed in the prostate of all benign(More)
Circulating tumour cells (CTCs) are independent predictor of prognosis in metastatic breast cancer. Nevertheless, in one third of patients, circulating tumour cells are undetected by conventional methods. Aim of the study was to assess the prognostic value of circulating tumour cells expressing mesenchymal markers in metastatic breast cancer patients. We(More)
The prognosis of metastatic cancer patients is still largely affected by treatment failure, mainly due to drug resistance. The hypothesis that chemotherapy might miss circulating tumour cells (CTCs) and particularly a subpopulation of more aggressive, stem-like CTCs, characterized by multidrug resistance, has been recently raised. We investigated the(More)
The prognostic value associated with the detection of circulating tumor cells (CTCs) in metastatic breast cancer by the CellSearch technology raise additional issues regarding the biological value of this information. We postulated that a drug-resistance profile of CTCs may predict response to chemotherapy in cancer patients and therefore could be used for(More)
We investigated the presence of human papillomaviruses (HPVs) types 16 and 18 DNA in formalin-fixed, paraffin-embedded tissues from the urinary bladder (46 transitional carcinomas and 10 non-neoplastic normal urinary samples) to find a possible role for HPV types in urinary tract cancerogenesis. The analysis was performed using polymerase chain reaction(More)
Antiangiogenic agents (AAs) have reported grater efficacy compared to interferon. Despite these advances, radiological complete response to therapy is rare. We meta-analyzed the incidence of complete response in patients treated with AAs and in controls in main randomized clinical trials for first-line therapy in metastatic renal cell carcinoma. PubMed was(More)
