The EORTC Quality of Life Study Group has developed a questionnaire for evaluating Quality of Life in international clinical trials: QLQ-C30. The purpose of the present work is to validate the third version of this questionnaire (3.0) for use in Spain. Two hundred and one head and neck cancer patients completed the QLQ-C30 at one or two time points during(More)
An open-label, non-randomized study evaluated the feasibility and efficacy of filgrastim (recombinant methionyl human granulocyte colony-stimulating factor, r-metHuG-CSF) to prevent mucositis induced by accelerated hyperfractionated radiotherapy (1.6 Gy b.i.d., total dose 67.2 Gy in six weeks with a two-week split) and concomitant chemotherapy (cisplatin,(More)
BACKGROUND Chemoradiotherapy is becoming an alternative to radical cystectomy among patients with bladder carcinoma invading muscle. In 1988, the authors began a protocol with methotrexate, vinblastine, doxorubicin, and cisplatin (M-VAC regimen) and radiotherapy for these patients. Traditionally, age has been considered a determinant factor thereby(More)
PURPOSE A prospective study with neoadjuvant chemotherapy and radiotherapy in patients with locally advanced esophagus carcinoma for evaluating: toxicity, response rate, pattern of recurrence, and survival after a long follow-up. METHODS AND MATERIALS Between 1983-1988, 40 patients with locally advanced squamous cell carcinoma of the thoracic esophagus(More)
The concept of quality has been linked to the health care world since the remote past and is one of the strategic elements on which the transformation and improvement of modern health systems is based. Study of quality in health care involves different approaches given that it holds different meanings for patients, professionals and managers. In recent(More)
PURPOSE To assess the tolerance, response rate, pattern of failure, and long-term survival of patients with unresectable nonsmall cell lung cancer treated with one cycle of induction chemotherapy followed by concurrent cisplatin and radiotherapy. METHODS AND MATERIALS From 1986 to 1988, 45 patients with histologically proven nonsmall cell lung cancer(More)
The effects of prostaglandin D2 (PG D2) and X-ray radiation on the growth and cell survival of C-6 rat glioma cells were evaluated. Exponentially growing monolayer cultures of C-6 glioma cells were incubated with various concentrations of PG D2 for 24 hours prior to X-ray irradiation. PG D2 exposure was associated with an inhibition of cell growth and a(More)
From 1987 to 1989, 42 patients with locally advanced squamous cell carcinoma of the head and neck (Stages III-IV, Mo) were randomized to receive radiotherapy (Group A) or three courses of induction chemotherapy followed by radiotherapy (Group B). There were 36 evaluable patients, 17 in Group A and 19 in Group B. The radiotherapy regimen was the same for(More)
