Pretreatment quality of life and functional status assessment significantly predict survival of elderly patients with advanced non-small-cell lung ca…

2005

Purpose To study the prognostic value for overall survival of baseline assessment of functional status, comorbidity, and quality of life (QoL) in elderly patients with advanced non—small-cell lung cancer treated with chemotherapy. Patients and Methods Data from 566 patients enrolled onto the phase III randomized Multicenter Italian Lung Cancer in the Elderly Study (MILES) study were analyzed. Functional status was measured as activities of daily living (ADL) and instrumental ADL (IADL). The presence of comorbidity was assessed with a checklist of 33 items; items 29 and 30 of the European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire QLQ-C30 (EORTC QLQ-C30) wer…

Randomized Phase II trial assessing estramustine and vinblastine combination chemotherapy vs estramustine alone in patients with progressive hormone-…

2004

Abstract Based on the results of combined data from three North American Phase II studies, a randomised Phase II study in the same patient population was performed, using combination chemotherapy with estramustine phosphate (EMP) and vinblastine (VBL) in hormone refractory prostate cancer patients. In all, 92 patients were randomised into a Phase II study of oral EMP (10 mg kg day continuously) or oral EMP in combination with intravenous VBL (4 mg m(2) week for 6 weeks, followed by 2 weeks rest). The end points were toxicity and PSA response in both groups, with the option to continue the trial as a Phase III study with time to progression and survival as end points, if sufficient responses…

Vinorelbine, cisplatin, and 5-fluorouracil as initial treatment for previously untreated, unresectable squamous cell carcinoma of the head and neck

1997

BACKGROUND The combination of vinorelbine (VNR), cisplatin (CDDP), and 5-fluorouracil (5-FU) has previously been shown to be active in recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCHNC). This multicenter Phase II study was carried out with the aim of evaluating the effectiveness of this combination in patients with previously untreated, unresectable locally advanced SCHNC. METHODS Sixty patients with previously untreated, unresectable SCHNC were treated with CDDP 80 mg/m2 on Days 1, 5-FU 600 mg/m2 as a 4-hour infusion on Days 2-5, and VNR 25 mg/m2 iv bolus on Days 2 and 8. There were 15 patients with laryngeal carcinoma, 19 patients with oropharyngeal carcinoma…

Unique pharmacology of KAR-2, a potential anti-cancer agent: absorption modelling and selective mitotic spindle targeting.

2008

Abstract Bis-indols are a large group of the anti-cancer agents, which effectively arrest the uncontrolled division of the cancerous cells. Their use in clinical chemotherapy is still limited because of: (i) the non-specific targeting of the mitotic cells; (ii) low bioavailability of the drugs. KAR-2 has been identified as a tubulin binding agent which displays significantly lower cytotoxicity but favourable anti-cancer potency than its mother molecule, vinblastine. The objective of this paper, on one hand, was to show that the human intestinal epithelial Caco-2 cells, used for pharmacokinetic studies display distinct sensitivity against KAR-2 and vinblastine due to their distinct targeting…

Pretreatment with potent P-glycoprotein ligands may increase intestinal secretion in rats.

2001

The expression of P-glycoprotein is induced in cell cultures upon exposure to various inducers. Therefore, the aim of the present study was to evaluate the in-vivo relevance of this observation, i.e. the influence of chronic pretreatments with selected drugs -- all of which are ligands to P-glycoprotein (P-gp) as demonstrated in radioligand binding studies and all of which have some or a considerable effect on P-gp expression in Caco-2 cells -- on the effective intestinal permeabilities of the model compound talinolol in rats employing in-situ single-pass intestinal perfusion of three different gut segments. Talinolol was selected, because it shows high selectivity for one of the exsorptive…

Progress in the development of early diagnosis and a drug with unique pharmacology to improve cancer therapy

2008

Cancer continues to be one of the major health and socio-economic problems worldwide, despite considerable efforts to improve its early diagnosis and treatment. The identification of new constituents as biomarkers for early diagnosis of neoplastic cells and the discovery of new type of drugs with their mechanistic actions are crucial to improve cancer therapy. New drugs have entered the market, thanks to industrial and legislative efforts ensuring continuity of pharmaceutical development. New targets have been identified, but cancer therapy and the anti-cancer drug market still partly depend on anti-mitotic agents. The objective of this paper is to show the effects of KAR-2, a potent anti-m…

Vinorelbine plus cisplatinum for the treatment of stage IIIB and IV non small cell lung carcinoma

1994

Thirty consecutive patients with stage IIIB-IV non small cell lung cancer were treated with a combination of cisplatin 80 mg/m2 on day 1 plus vinorelbine 25-30 mg/m2 on days 1, 8. This cycle was repeated every 3 weeks. The overall response rate was 46%, with 1 patient showing a complete response and 13 patients (43%) a partial response with a mean duration of 8.4+ months. Six patients had a stabilization and 10 progressed. The main toxicities were represented by myelosuppression and nausea/vomiting. Grade 3 leukopenia was seen in 33% of cases, grade 2 thrombocytopenia in 12%, and phlebitis in the injection vein in 16%. Mild constipation was also recorded. The combination of cisplatin plus v…

The prognostic value of biological markers in paediatric Hodgkin lymphoma

2015

Abstract Background Many biological and inflammatory markers have been proposed as having a prognostic value at diagnosis of Hodgkin lymphoma (HL), but very few have been validated in paediatric patients. We explored the significance of these markers in a large population of 769 affected children. Patients and methods By using the database of patients enrolled in A.I.E.O.P. (Associazione Italiana di Emato-Oncologia Pediatrica) trial LH2004 for paediatric HL, we identified 769 consecutive patients treated with curative intent from 1st June 2004 to 1st April 2014 with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine), or hybrid COPP/ABV (cyclophosphamide, vincristine, prednisone, pr…

Studies on vinblastine-induced autophagocytosis in mouse liver

1980

The origin of the membranes of autophagic vacuoles (AV) and acquisition of acid phosphatase into AV's were studied in vinblastine-induced autophagocytosis (VBL, 50 mg/kg, i.p.) in mouse hepatocytes. Using unbuffered OsO4, very intense staining was observed in the outer cisternae of the Golgi apparatus and also frequently in the cavity between the double membranes obviously destined to form AV's as well as in the cavity between the double membranes of newly formed AV's. There may occur a transformation process in the membranes limiting an AV analogous to that observed at the Golgi cisternae. The transformation of the outer AV membrane occurs independently of fusion with lysosomes. Inosine di…
