Interactions occurring between malignant cells and the stromal microenvironment heavily influence tumor progression. We investigated whether this cross-talk affects some molecular and functional aspects specifically correlated with the invasive phenotype of breast tumor cells (i.e. adhesion molecule expression, membrane fluidity, migration) by co-culturing(More)
Postoperative recurrence after ileo-colonic resection is a feature of Crohn's Disease (CD), almost 73% of patients show endoscopic recurrence at 1 year and 90% at 3 years. After surgical resection for CD, symptoms may be related to the surgical resection itself. Moreover, the development of an early severe endoscopic recurrence within 1 year represents a(More)
The brain type (BB) isoenzyme of creatine kinase (CK) is a very sensitive marker of estrogen action in rat uterus and in experimental mammary tumors. In order to detect useful markers for estrogen dependent human breast cancer cell proliferation we measured CK levels and isoenzyme composition in the CG5 cells, an estrogen supersensitive variant of the MCF-7(More)
Cathepsin-D (Cath-D) expression was evaluated by an immunoradiometric assay in 67 primary endometrial carcinomas and 70 cervical cancers. In the endometrial tumours, an inverse correlation was observed between Cath-D levels and stage (P = 0.027) and myometrial invasion (P = 0.046). A significant correlation between Cath-D levels and hormone receptor status(More)
Tissue samples from 57 patients with neuroepithelial tumors (25 glioblastomas, 18 anaplastic astrocytomas, and 14 astrocytomas) were analyzed in order to evaluate the presence of estrogen, progesterone, glucocorticoid, and androgen receptors. Glucocorticoid- and androgen-specific binding proteins were present in 38.6% and 21.6% of the cases, respectively.(More)
The effect of natural beta-interferon (beta-IFN) on cell proliferation and steroid receptor level was investigated in CG-5 human breast cancer cell line. beta-interferon determines an appreciable diminution of cell growth, at concentrations ranging from 100 to 1000 IU/ml, which is enhanced when serum content of the culture medium is lowered. Low(More)
The aim of the present trial was to investigate the protective effects on ovarian function, and the efficacy and tolerability of goserelin added to adjuvant chemotherapy for early breast cancer. Following surgical treatment, 64 premenopausal patients with early breast cancer received goserelin 3.6 mg (every 28 days for 1 year) and an adjuvant treatment(More)
Based on the additive or synergistic antiproliferative effect of interferon and tamoxifen on breast cancer cell lines and on preclinical and clinical data on retinoids alone and in combination with antiestrogen or interferon, we designed a pilot phase II study to test the toxicity of simultaneous administration of interferon-beta (IFN-beta), retinoids (R),(More)
Tamoxifen (T) is the mainstay of hormonal treatment and is able to give high response rates in selected postmenopausal women with advanced breast cancer (ABC). Nevertheless, even in responders, invariably resistance to hormones is developed. In a previous paper we reported that in a subset of patients (pts) with metastatic breast cancer the resistance to(More)
In the current study we investigated the effect of two different doses of natural interferon-beta (IFN-beta) on steroid hormone receptors in 45 patients with advanced breast cancer. IFN-beta seems to regulate the receptor mechanisms, inducing in cutaneous metastases an increase of oestrogen and progesterone receptors. Moreover, using IFN-beta and tamoxifen(More)
