Apport de la gemcitabine dans le traitement du cancer du pancréas avancé

Introduction. - Pancreatic cancer is one of the most common tumor of the gastrointestinal tract. Current knowledge and key points. - Because this malignant is usually diagnosed at an advanced stage, its prognosis is poor, and patients are generally considered incurable diagnosis. The traditionnal palliative approach to management of this tumor is chemotherapy. The most widely used agent is 5-FU, alone or in combination. Benefits of the treatment are still poor: the overall survival time rarely exceeds 5 months, and no study has shown a response rate greater than 20%. Future prospects and projects.- Gemcitabine, a new antinucleoside agent, has led to promising results, as several phase II and III studies have demonstrated an increase in survival as compared with 5-FU, the overall 1-year survival rates being 18% and 2%, respectively (p < 0002). Furthermore, even if only discrete results in terms of objective response rate have been achieved, gemcitabine decreases disease-related symptoms, thus benefiting to the patient's quality of life. The concept of clinical benefit therefore appears to be an important judgement criteria in the assessment of chemotherapy efficacy, and will certainly be extended to other malignant neoplasms.
