Cost-minimization analysis of a phase III trial comparing concurrent versus sequential radiochemotherapy for locally advanced non-small-cell lung cancer (GFPC-GLOT 95-01).

BACKGROUND: We conducted an economic analysis of a phase III clinical trial comparing sequential radiochemotherapy (RT-CT) with concurrent RT-CT in patients with locally advanced non-small-cell lung cancer. PATIENTS AND METHODS: The trial was a randomized multicenter study comparing three cycles of chemotherapy (arm A) followed by radiotherapy against an RT-CT combination (two cycles of platinum etoposide) followed by two cycles of platinum-vinorelbine (arm B). The economic analysis adopted the payer's perspective and only included direct costs. Costs (euro, 1996-2003) were recorded until the cut-off date. A cost minimization analysis and a sensitivity analysis were carried out. RESULTS: Data from 173 patients were used in the economic study. Protocol costs tended to be higher in arm B, while relapse costs were significantly higher in arm A. The total number of hospital days was higher in arm B. The average total cost per patient was euro16,074 in arm A and euro15,245 in arm B (P=0.15). The cost minimization analysis favored arm B. This advantage persisted in the sensitivity analysis. CONCLUSIONS: Concurrent RT-CT was not the more costly strategy in this phase III trial, despite lengthier hospitalization for toxicity. Other studies of similar design are needed to confirm these results in future randomized trials.

[Ileum inflammatory fibroid polyp revealed by intussusception. About one familial case].

INTRODUCTION: Acute ileum intussusception is a frequent and mostly benign condition in childhood. Conversely, it is a rare condition during adulthood and generally associated with an underlying malignancy. We report a familial form of benign inflammatory fibroid polyps, revealed by an acute ileum intussusception. EXEGESIS: A 41-year-old man, whose mother had undergone three surgical procedures for acute ileum intussusception associated with inflammatory fibroid polyp, was admitted for a abdominal pain that started three month ago. The patient displayed alteration of the intestinal transit, weight loss and sub-occlusive syndrome. Upper and lower endoscopies, performed before admission, were normal. In the emergency room, the abdominal computed tomography-scan revealed an acute intussusception of the last loop of the small intestine, probably caused by a tumor and leading to an occlusive syndrome. Surgical resection and histological analysis concluded to an inflammatory fibroid polyp. Clinical outcome was excellent. CONCLUSION: Inflammatory fibroid polyp is always a benign tumor. It is usually isolated, expressing itself mainly in the form of an acute intussusception when located in the small bowel. The familial form presented here is exceptional and illustrates the possibility of an inherited transmission of this disease. However the pathogenesis of this type of polyp is still unclear.

[Efficacy of gefitinib (Iressa) in the treatment of an inoperable bronchioloalveolar cell carcinoma].

INTRODUCTION: Bronchioloalveolar cell carcinoma (BAC) is a rare bronchial tumour. At present the only curative treatment is surgery and inoperable cases are often resistant to radio and chemotherapy. CASE REPORT: A 76 year old woman was treated surgically for a BAC, stage T2N0M0. Three months later she presented with cough and dyspnoea. Investigation revealed recurrence of the disease with bilateral pulmonarymetastases. She then received two courses of chemotherapy leading, at best, to stabilisation of the disease. At that time the treatment decision was simple observation. Six months later when there was progression of the bilateral lesions treatment was initiated with gefitinib 250 mg daily. This lead to rapid improvement in the clinical symptoms and the chest x-ray and CT scan showed evidence of a partial response that persisted one year after the beginning of treatment. CONCLUSION: This observation describes the effect of gefitinib in the treatment of inoperable BAC for which there is, at present, no effective therapy.
