Subcutaneous interleukin-2 in combination with medroxyprogesterone acetate and antioxidants in advanced cancer responders to previous chemotherapy: phase II study evaluating clinical, quality of life, and laboratory parameters.

We carried out an open, non-randomized phase II study including all patients treated with whatever chemotherapy or combined modality regimen for whatever cancer who were in clinical objective response (complete response, CR, or partial response, PR) or stable disease (SD). The treatment consisted of administration of recombinant interleukin-2 (rIL-2) at a dose of 1.8 MIU subcutaneously three times/week (every other day) for the first 2 weeks of every month plus medroxyprogesterone acetate (MPA) 500 mg/day every other day plus antioxidant agents alpha-lipoic acid 300 mg/day and N-acetyl cysteine 1800 mg/day or carbocysteine lysine salt oral solution 2.

Antioxidant agents are effective in inducing lymphocyte progression through cell cycle in advanced cancer patients: assessment of the most important laboratory indexes of cachexia and oxidative stress.

This study assessed in a wide population of advanced cancer patients the biological parameters relevant to cancer cachexia, such as serum levels of proinflammatory cytokines (IL-1beta, IL-6, TNFalpha), IL-2, acute-phase proteins (C-reactive protein and fibrinogen), leptin, and relevant to oxidative stress (OS), such as ROS, body antioxidant enzymes GPx and SOD. We also studied the ability of effective antioxidant agents alpha-lipoic acid (ALA), N-acetyl cysteine (NAC), and amifostine (AMI) added into culture to induce lymphocyte progression through the cell cycle, namely to enter into S phase. Additionally, we assessed the most significant clinical indexes of nutritional status such as body mass index and disease progression such as stage and ECOG-PS in the same cancer patient population.

Six-week induction chemotherapy followed by concomitant chemoradiation therapy in stage IV head and neck cancer: a phase II study with organ-sparing purposes.

The purpose of the study was to assess response rate, clinical outcome, organ/function preservation and toxicity in head and neck cancer patients treated with induction chemotherapy followed by concomitant chemoradiotherapy and, when necessary, limited surgery. The study was a phase II non-randomized trial. Induction chemotherapy consisted of 6 weekly doses of carboplatin at AUC of 2 and docetaxel 30 mg/m(2) (1 h) followed by 5 cycles of docetaxel 25 mg/m(2)/day 1, 5-FU 600 mg/m(2) c.

The impact of different antioxidant agents alone or in combination on reactive oxygen species, antioxidant enzymes and cytokines in a series of advanced cancer patients at different sites: correlation with disease progression.

In the present study we tested the ability of different antioxidant agents, used alone or in combination, to reduce the reactive oxygen species (ROS) levels and to increase the glutathione peroxidase (GPx) activity. Moreover, we tested the ability of such antioxidant agents to reduce the serum levels of proinflammatory cytokines IL-6 and TNFalpha. Fifty-six advanced stage cancer patients with tumors at different sites were included in the study: they were mainly stage III (12.

Phase II clinical trial of local use of GM-CSF for prevention and treatment of chemotherapy- and concomitant chemoradiotherapy-induced severe oral mucositis in advanced head and neck cancer patients: an evaluation of effectiveness, safety and costs.

In the present open non-randomized phase II study we looked for effectiveness, safety, tolerability and costs of locally applied GM-CSF in preventing or treating mucositis in patients receiving chemotherapy or chemoradiotherapy for head and neck cancer. In addition to clinical mucositis scoring system, the effects of treatment with GM-CSF were evaluated by its impact on patient quality of life and by laboratory immunological assays such as serum proinflammatory cytokines, IL-2 and leptin. The trial was designed to assess the effectiveness of local GM-CSF treatment in two different settings: i) prophylaxis of mucositis; ii) treatment of mucositis.

Phase II study of subcutaneously administered interleukin-2 in combination with medroxyprogesterone acetate and antioxidant agents as maintenance treatment in advanced cancer responders to previous chemotherapy.

An open, non-randomized phase II study was carried out including patients with advanced solid tumors who achieved an objective response or disease stabilization as a result of previous chemotherapy, to receive a maintenance treatment with recombinant interleukin-2 (rIL-2) plus medroxyprogesterone acetate (MPA) plus antioxidant agents alpha-lipoic acid (ALA) and N-acetyl cysteine (NAC). The first study endpoints were to define clinical outcome and toxicity as well as the evaluation of quality of life. As secondary endpoints we measured the changes of lymphocyte absolute count, the serum levels of proinflammatory cytokines, IL-2, C-reactive protein (CRP) and leptin after treatment.

Induction chemotherapy followed by concomitant chemoradiation therapy in advanced head and neck cancer: a phase II study for organ-sparing purposes evaluating feasibility, effectiveness and toxicity.

The purpose of the study was to assess response rate, clinical outcome, organ/function preservation and toxicity in head and neck cancer patients treated with induction chemotherapy followed by concomitant chemoradiotherapy and, when necessary, limited surgery. The study design was a phase II non-randomized trial in hospitalized patients setting. The treatment plan consisted of 3 cycles of induction chemotherapy with cisplatin, fluorouracil (5-FU), l-leucovorin and interferon alpha2b (PFL-IFN) followed by 7 cycles of 5-FU, hydroxyurea and concomitant radiation for 5 days (FHX) for a total radiation dose of 70 Gy.
