Gastric cancer in young patients--is there any hope for them?

Gastric cancer usually affects people older than sixty years. This type of cancer is very rare in adults under thirty years of age. In addition, the prognosis in this part of population is grave due to the high incidence of undifferentiated tumours and advanced stage at time of diagnosis. Radical surgery affords the only chance for long term survival, but even this option is often limited upon finding locally advanced disease or peritoneal seeding. The following are case studies of three young adults from a group of 45 patients, who were treated between January 1st, 2000 and December 31st, 2003.

Treatment of deep cartilage defects of the knee using autologous chondrograft transplantation and by abrasive techniques--a randomized controlled study.

AIM OF THE STUDY: To compare outcomes of surgical treatment of deep cartilage defects of the knee in a group of patients treated by autologous chondrograft transplantation versus patients treated by abrasive techniques. MATERIALS AND METHODS: An original method of chondrograft preparation based on cultivated autologous chondrocytes in a three-dimensional carrier - fibrin glue (Tissucol, Baxter, Austria) has been described. Preclinical tests in human cadavres and porcine models have established the possibility of chondrograft use in humans. Of the 50 patients included in the study, 25 patients (50%) underwent autologous chondrograft transplantation (group I) and 25 patients (50%) were treated using abrasive techniques according to Johnson (group II). These two groups were similar with respect to age, size of defect, depth and localization, and presence of concomitant knee injuries. The Lysholm knee and IKDC (International Knee Documentation Committee) subjective scores were used to evaluate the results. RESULTS: The preoperative value of the Lysholm knee score for patients in group I was 47.60 points; 5 months after surgery 77.20 points; and 12 months after surgery 86.48 points. The values for the Lysholm knee score for patients in group II preoperatively, 5 months postop, and 12 months postop were 52.60, 69.20, and 74.48 respectively. Results 12 months after surgery were significantly better in group I as compared to group II (p < 0.001). The preoperative value of the IKDC subjective score in group I was 41.28 points; 5 months after surgery 67.00 points; and 12 months after surgery 76.48 points. The values for the IKDC subjective score in group II preoperatively, 5 months postop, and 12 months postop were 45.00, 62.28, and 68.08 respectively. Results 12 months after surgery were significantly better in group I when compared to group II (p < 0.05). CONCLUSIONS: The results obtained in this study have confirmed the better outcome in patients treated with autologous chondrograft transplantation. This original method was found to be just as effective as abrasive techniques. We recommend its use in clinical practice.
