PURPOSE: We evaluated the ability of endo-rectal coil MRI (ER-MRI) to predict the local pathological stage of prostate cancer prior to radical prostatectomy and compared the results with those of transrectal ultrasonography (TRUS). MATERIALS AND METHODS: ER-MRI using high field magnets (1.5 Tesla) were performed in 22 patients (mean age 62.8 years, range 51-73) with clinically localized prostate cancer before radical prostatectomy. Of the 22 patients, 17 patients were also assessed by TRUS. The results of the imaging techniques were compared with the post-operative histopathological findings. As one patient with pelvic lymph node metastasis, which was detected on frozen-section examination during surgery, was spared radical prostatectomy, the final evaluation included 21 patients. RESULTS: DSeven of the 21 patients (33%) were found to have extraprostatic extension (EPE), and 5 had seminal vesicle invasion (SVI). The sensitivity and specificity for diagnosing EPE using ER-MRI were 62.5% and 84.6%, respectively, and 16.7% and 100% with TRUS. The sensitivity and specificity for diagnosing SVI were 80.0% and 93.8%, respectively with ER-MRI, and 0% and 92.3% with TRUS. The accuracy of predicting SVI was 90.5% with ER-MRI compared to 70.6% with TRUS. CONCLUSIONS: ER-MRI was significantly better than TRUS for determining the local extent of prostatic cancer and for prediction of SVI in the preoperative staging of clinically localized prostate cancer.

From Sept. 1987 to Mar. 1993, 14 cases of pelvic bone tumors took surgical treatment. Male to female ratio was 7:7, with an average age of 31.9 years. Pathological diagnosis were chondrosarcoma 7(1 ; secondary), metastatic thyroid cancer 2, and each one case of giant cell tumor, desmoplastic fibroma, metastatic synovial sarcoma, malignant fibrous histiocytoma(MFH), and enchondroma. According to the Enneking's classification for the type of surgical resection, we performed 4 cases of type II+III resection, 4 type IA, 2 type I+II, 2 type III, and each one of II and IIA+III. Types of reconstruction were hip fusion(3 cases), heat treated autogenous bone graft combined with total hip replacement arthroplasty(4), bone graft(2), cement spacer(1) or saddle prothesis(1). Simple resection was done for 3 cases. Wide surgical margin was achieved in 12 cases, marginal margin in 1 and intralesional magin in 1. Complications occurred in 3 cases(21.4%) : 1 graft failure ; 1 lymphedema ; and 1 delayed union. The average follow-up period was 27.4(8-60) months. During follow up, lung metastasis developed in MFH case but no local recurrence was noted in all. By the criteria of American Musculoskeletal Tumor Society(MSTS), the average score for functional activities was 21(70% of normal). The function of the extremity with reconstructed or undestroyed pelvic ring was better than that with disrupted pelvic ring(functional scores ; 24.6 vs 12.3 respectively). Due to the Korean life style using hypocaust, fused hip was not good for indoor activity. For the malignant pelvic bone tumor not involving femoral neurovascular bundle, limb-salvage using internal pelvectomy and reconstruction of pelvic ring can be indicated as a surgical procedure, instead of the hindquarter amputation.
