Mitomycin C plus vindesine plus etoposide (MEV) versus mitomycin C plus vindesine plus cisplatin (MVP) in stage IV non-small-cell lung cancer: A phas…
1996
Purpose : To compare mitomycin C plus vindesine plus etoposide (MEV) vs. mitomycin C plus vindesine plus cisplatin (MVP) in the treatment of stage IV non-small-cell lung cancer. Patients and methods : 204 patients were entered in a phase III multicentre randomised trial from June 1990 to December 1994 and stratified according to the ECOG performance status (0-1 vs. 2). MVP was given in the following dosages : mitomycin C 8 mg/m 2 + vindesine 3 mg/m 2 + cisplatin 100 mg/m 2 i.v. day 1 and vindesine 3 mg/m 2 i.v. day 8 with cycles repeated every 4 weeks. MEV was given in the following dosages : mitomycin C 8 mg/m 2 + vindesine 3 mg/m 2 i.v. day I and etoposide 100 mg/m 2 i.v. days 1 to 3 with…
Combined Carboplatin plus Ifosfamide and Cisplatin in Patients with Advanced Ovarian Carcinoma. A Phase I–II Study
1998
Abstract Because of the relative lack of overlapping toxicity, carboplatin (PPL) and cisplatin (CDDP) can be easily combined for treatment of ovarian cancer to increase total platinum dose intensity. Ifosfamide (IFO), one of the most effective single agents in ovarian cancer, has a low hematological toxicity when administered in continuous infusion. From January 1991 to December 1993, 34 patients with advanced ovarian cancer, previously untreated with chemo- or radiotherapy, were enrolled in a phase I–II study with the aim of determining the maximum tolerated dose (MTD) of CDDP (on day 8 of a 28-day cycle) in combination with PPL (300 mg/m 2 on day 1) and IFO (4,000 mg/m 2 /24 h by continuo…
Activity and toxicity of oxaliplatin plus raltitrexed in 5-fluorouracil refractory metastatic colorectal adeno-carcinoma
2004
Background: This study evaluated the antitumor efficacy and safety of a novel oxaliplatin/raltitrexed combination in pretreated advanced colorectal cancer patients. Patients and Methods: Forty-five patients with 5-fluorouracil-refractory metastatic colorectal cancer received raltitrexed 3.0 mg/m2 as a 15-minute intravenous (i.v.) infusion, followed 45 min later by l-OHP 130mg/m2 iv as 2-h venous infusion on 1 day every 3 weeks. All patients had histologically proven metastatic colorectal cancer, age 18-75, measurable disease and normal baseline biological values. Most patients (60%) had >2 disease sites. All patients were assessed for safety and also for response according to an intent-to-t…
Linfoma a cellule B (maltoma) dello stomaco ed infezione da Helicobacter pylori
1996
The authors, after illustrating physiopathologic aspects of gastric MALTomas, examine the H.P. infections and the possible relations between this kind of bacterium and gastric MALTomas. They hypothesize that H.P. infection represents an important predisposition to gastric lymphoma, due to anatomopathological modifications over gastric mucosa. They conclude that a decreasing of gastric lymphoma could be correlatable an opportune eradication of H.P. despite of at moment it's impossible hypothesize a marked decreasing of lymphoma by an eradication of H.P.
Antioxidant defenses in a B16 melanoma line resistant to doxorubicin: an in vivo study.
1991
A B16 melanoma line was repeatedly transplanted subcutaneously in C57BL/6 mice. On day 4 after every transplant, the animals were treated with doxorubicin (DXR), 10 mg/kg i.p. The aim of the work was to develop an in-vivo model of resistance to the antiblastic in order to analyze some possible mechanistic aspects of the process in the course of time. After 16 transplants and treatments the melanoma completely lost its sensitivity to the antiproliferative effects of maximal tolerated doses of DXR and showed over-expression of P-glycoprotein. Compared to the parental line, the in vitro resistance index was 4.6. After 27 transplants and treatments the melanoma did not increase its in vitro res…

Effects of Tumor Necrosis Factor-Alpha on Growth and Doxorubicin Sensitivity of Multidrug Resistant Tumor Cell Lines
1993
Biological agents might offer various therapeutic opportunities in the treatment of cancer, including a direct and/or host- mediated antiproliferative effect as well as the possibility to favourably modulate tumor sensitivity to antineoplastic drugs (Alexander et al., 1987; Kikuchi et al., 1992; Wadler and Schwartz, 1990). However, information on their activity on chemoresistant tumors is still scanty (Billi et al., 1991; Bonavida et al., 1989; D’Alessandro, 1993; Fruehauf et al., 1991; Liddill et al., 1988; Mihich and Ehrke, 1991). Here we have focused on tumor necrosis-alpha (TNF-α) and studied its in vitro effects on the growth of two tumor cell lines, the mouse B16 melanoma and Friend e…
A Phase II Trial of Mitoxantrone plus Cyclophosphamide and 5-Fluorouracil in Modulation with Levo-Folinate for Advanced Breast Cancer Patients
1995
Advanced breast cancer remains a major clinical problem. Current chemotherapy regimens are able to induce a clinical response in many patients but do not appear to influence significantly patients' survival. The use of new drugs such as mitoxantrone with a predicted lower toxicity and biochemical modulation of 5-fluorouracil with levo-folinate are extensively studied research areas that could combine good therapeutic efficacy with the maintenance of an acceptable quality of life. 34 patients with advanced breast carcinoma were included in the study. Only 4 women had received prior chemotherapy for advanced disease. Treatment plan was: 5-fluorouracil 400 mg/m2 + l-leucovorin 100 mg/m2 days 1…
Effect of Buthionine Sulfoximine on the Sensitivity to Doxorubicin of Parent and MDR Tumor Cell Lines
1994
We have studied the interaction of glutathione-depleting concentrations of buthionine sulfoximine (BSO) with the anti-proliferative activity of doxorubicin (DXR) in three tumor lines, the mouse B16 melanoma. Friend erythroleukemia and the human K562 leukemia, both as DXR-sensitive and-resistant (with typical multidrug resistance) variants. BSO significantly enhanced the DXR effects in the wild-type Friend and K562 leukemias, and especially in the drug-resistant subline of Friend leukemia. BSO did not modify DXR accumulation and retention in the latter clone. Moreover, neither BSO nor verapamil used alone completely reversed the resistance to DXR of this cell line; their combination was more…
Metronomic chemotherapy for advanced breast cancer patients in the real world practice: Final results of the VICTOR-6 study
2019
Abstract Metronomic chemotherapy (mCHT) refers to the minimum biologically effective dose of a chemotherapy agent given as a continuous dosing regimen, with no prolonged drug-free breaks, that leads to antitumor activity. Aim of the present study is to describe the use of mCHT in a retrospective cohort of metastatic breast cancer (MBC) patients in order to collect data regarding the different types and regimens of drugs employed, their efficacy and safety. Between January 2011 and December 2016, data of 584 metastatic breast cancer patients treated with mCHT were collected. The use of VRL-based regimens increased during the time of observation (2011: 16.8% - 2016: 29.8%), as well as CTX-bas…
5-Fluorouracil plus interferon α-2a compared to 5-fluorouracil alone in the treatment of advanced colon carcinoma: A multicentric randomized study
1998
Biochemical modulation is one of the most interesting fields in cancer chemotherapy. Interferon-alpha (IFNalpha) is a cytokine that is able to influence the pharmacodynamics of 5-fluorouracil (5FU) through a number of mechanisms. With the aim of confirming some data emerging from the literature, we initiated a multicentric randomized study comparing the combination of 5FU and IFNalpha-2a with 5FU alone in the treatment of advanced or metastatic colon cancer. A group of 205 colon cancer patients (104 in the 5FU arm and 101 in the 5FU + IFNapha-2a arm) were included in the final intention-to-treat analysis. Rectal cancers were not considered eligible. All patients had measurable disease, were…
Interleukin 3 in the treatment of chemotherapy induced thrombocytopenia.
1998
We enrolled 19 cancer patients (11 females, 8 males) with thrombocytopenia after standard dose of chemotherapy to receive IL3 10 mg/kg/day s.c. until hematologic recovery. Therapeutic success was obtained in 69.6% of cycles; a major response in 39.3% and a minor response in 30.3% of cycles. We obtained the best results in case of platelet count <49,000/mm3. The main toxicity was a flu-like syndrome. In two cycles (6%) we registered allergic episodes with flushing and lipothymia. In the 47% of cycles evaluable for toxicity no side effect was registered.
