Induction Therapy With Cisplatin, 5-Fluorouracil, Leucovorin, and Paclitaxel in Patients With Head and Neck Cancer.

BACKGROUND/AIM: This study aimed to evaluate the toxicities and response rate of a modified TPF (docetaxel, cisplatin, and 5-fluorouracil) protocol in patients with locally advanced head and neck cancer (ECOG performance status ≤1). PATIENTS AND METHODS: Induction treatment consisted of cisplatin 25 mg/m2/day as a 90 min infusion for three consecutive days, leucovorin 20 mg/m2/day as a bolus for four consecutive days, 5-fluorouracil (5-FU) 370 mg/m2/day as a bolus for four consecutive days, and paclitaxel 60 mg/m2 as a 1-h infusion on Days 1, 8, and 15, repeated every 3-4 weeks (twelve cycles to 6 patients). RESULTS: The main toxicities were grade 1 neuropathy, mucositis, and fatigue. There were four episodes of severe toxicities (grade ≥3). There was one early death, and 2 patients were discontinued due to hematological toxicity. Other side effects included neutropenia, nausea, diarrhea, and vomiting. CONCLUSION: Induction therapy with cisplatin, 5-fluorouracil, leucovorin, and paclitaxel in head and neck cancer is not feasible because of severe toxicity.

Uncaria tomentosa (cat's claw) improves quality of life in patients with advanced solid tumors.

OBJECTIVE: Cat's claw (Uncaria tomentosa) is a native Amazon plant that exhibits anti-inflammatory and antitumor properties. We wanted to assess its activity for symptom management of terminal cancer patients. METHODS: This prospective phase II study assessed the effects of a 100-mg dose of a dry extract of U. tomentosa three times per day in patients with advanced solid tumors who had no further therapeutic options and a life expectancy of at least 2 months. The European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C30) and Functional Assessment of Chronic Illness Therapy - Fatigue questionnaires were used to assess the participants' quality of life, the Hospital Anxiety and Depression Scale questionnaire was used to assess anxiety and depression, and the Pittsburgh Sleep Quality Index was used to assess sleep quality. In addition, several biochemical and inflammatory parameters were analyzed. RESULTS: Fifty-one volunteers were recruited. Their median age was 64 (range, 33-85) years, and 47% of patients were female. More than 65% of patients had scores on the Karnofsky Performance Scale of 80% or less. Treatment improved the patients' overall quality of life (p=0.0411) and social functioning (p=0.0341), as assessed by the EORTC QLQ C-30, and reduced fatigue (p=0.0496) according to the Chalder Fatigue Questionnaire. None of the biochemical or inflammatory parameters assessed (interleukin-1 and -6, C-reactive protein, tumor necrosis factor-α, erythrocyte sedimentation rate, and α-1-acid glycoprotein) changed significantly. No tumor response was detected according to the Response Evaluation Criteria In Solid Tumors; however, the disease stabilized for more than 8 months in four participants. The medication was well tolerated by most patients. CONCLUSION: Use of cat's claw might be beneficial in patients with advanced cancer by improving their quality of life and reducing fatigue. The mechanism of action does not seem to be related to the anti-inflammatory properties of this plant.
