It is well accepted that the presence of estrogen receptor (ER) in breast cancer patients correlates with a better prognosis and a higher probability of response to hormonal treatment. Recent data suggest the ER variant isoforms may be common in clinical breast cancer. Furthermore, an association between the expression of such variants and the development(More)
Immunosuppression has been often associated with the course of malignant diseases. In the present study, the proliferation of peripheral blood mononuclear cells (PBMCs) in response to mitogenic stimulation with phytohaemagglutinin (PHA) was assessed prospectively in 90 patients with stage I-III breast cancer. Whereas PHA-induced proliferation of PBMCs(More)
Anti-Her-2/neu antibody is known to induce apoptosis in HER-2/neu overexpressing breast cancer cells. However, exact regulatory mechanisms mediating and controlling this phenomenon are still unknown. In the present study, we have investigated the effect of anti-Her-2/neu antibody on apoptosis of HER-2/neu overexpressing human breast cancer cell lines(More)
The present phase II trial was undertaken to assess the efficacy and toxicity of a combination of paclitaxel and carboplatin as first-line chemotherapy in patients with metastatic transitional cell carcinoma of the urothelium. Twenty patients (age range 50-79 years; inclusion criteria: WHO performance status 0-2, no previous cytotoxic treatment) with(More)
We report a constitutional point mutation of codon 278 in exon 8 of the TP53 gene that has not yet been described as a germ-line mutation. A 52-year-old female developed multiple primary malignancies (liposarcoma, breast cancer, malignant histiocytoma, occult adenocarcinoma). The mutation found in her tumour and peripheral blood lymphocyte DNA is a cytosine(More)
Purpose. The present prospective randomized adjuvant trial was carried out to compare the toxicity, feasibility and efficacy of augmented chemotherapy added to hyperfractionated accelerated radiotherapy after wide or marginal resection of grade 2 and grade 3 soft tissue sarcoma (STS).Patients and methods. Fifty-nine patients underwent primary surgery by(More)
BACKGROUND In Her2-positive advanced breast cancer, the upfront use of trastuzumab is well established. Upon progression on first-line therapy, patients may be switched to lapatinib. Others however remain candidates for continued antibody treatment (treatment beyond progression). Here, we aimed to identify factors predicting for activity of second-line(More)
Uncontrolled proliferation and a defect of apoptosis constitute crucial elements in the development and progression of tumours. Among many other biological response modifiers known to influence these mechanisms, the efficacy of retinoids and interferons in the treatment of various malignant entities is currently matter of discussion. In the present study,(More)
