Impact on the quality of remaining life of treatment with self-expandable metal prostheses in patients with inoperable esophago-cardial cancer. Results of a study of 107 consecutive patients treated with Ultraflex-type prostheses.
BACKGROUND
Self-expanding metal stents are a new alternative for palliation of esophagocardial malignancies. We evaluated the impact of these stents on the quality of remaining life in patients affected by inoperable esophago-cardial cancer.


METHODS
Between September 1992 and September 1997, 102 patients underwent implantation of self expanding metal stents for palliation of dysphagia due to esophagene or cardial cancer (76 patients), or for locally recurrent carcinoma after surgery (14 patients), lasertherapy (13 patients) or radiotherapy (5 patients). Stents were implanted under radiological and endoscopic control in patients under mild sedation.


RESULTS
Successful stent implantation was achieved in 102/107 patients (95.3%). Early complications were observed in 4.9% and per-operative mortality was 1.96%. After stent implantation the dysphagia score improved from 3.0, on average, to 0.5, on average. Late complications were evidenced in 25.5%. Weight gain was evidenced in 24.5% and the performance status improved in 14.3%. The mean survival time was 6.9 months.


CONCLUSIONS
Self expanding metal stents are an effective alternative for palliation of malignant dysphagia due to esophageal and cardial cancers.
