Surgical Treatment of Mediastinal Tumor in Prince of Songkhla University
A retrospective review of mediastinal tumors treated in our surgical unit at Prince of Songkhla University from June 1982 to June 2001 was presented. The aim of this study was to determine the incidence, nature of tumor found in various locations in the mediastinum and to evaluate our surgical results in patients with mediastinal tumors.
During the study period of 19 years, we operated upon 96 cases of mediastinal tumors, 51 males and 45 females, age range from 5 months to 64 years old. There were 85 Thais, 6 Thai-Chineses and 5 Thai-Moslems. The majority of patients (81.25%) were symptomatic and the anterior mediastinum was the most common location (65.6%). Teratoma was the most common tum or in our study (32.29%). The tumor was benign histology in 63.5per cent and malignant histology in 36.5 per cent.
Conclusion: The incidence of anterior mediastinal tumor and teratoma was slightly higher than in other reports. The relation between asymptomatic patients and benign histology was strong in our study. We also found the incidence in Thai-Moslem was lower than Thais because they infrequently has routine chest x-ray check up despite the fact that in some provinces in Southern Thailand the Thai-Moslem population is over 90 percent. The routine chest x-ray check up may increase the chance of diagnosis made for mediastinal tumor and the result of treatment may be improved.
