ABSTRACT
PURPOSE: Accurate preoperative assessment of breast cancer is important to determine the extent of disease and the plan for surgery. The purpose of this study was to evaluate the efficacy of preoperative breast magnetic resonance imaging (MRI) in breast cancer patients. METHODS: Between January 2001 and October 2007, 457 consecutive patients who had undergone surgical treatment for breast cancer were retrospectively studied. We compared 303 patients from the non-preoperative MRI group (group A) to 154 patients from the preoperative MRI group (group B). The impact of preoperative MRI was evaluated for each patient with regard to changes in therapeutic intervention. RESULTS: MRI alone revealed 17 new lesions. The results of the MRI led to a change in 9.1% of the planned surgical procedures. Tumor size was more accurately defined in patients undergoing MRI than in those undergoing ultrasound imaging. CONCLUSION: Breast MRI could be recommended as a preoperative diagnostic procedure in patients allocated to receive breast conservation surgery, because MRI may reveal unsuspected multifocal or multicentric tumors or carcinoma infiltrations and may result in changes in therapy.

From the period of April 1991 to March 1992, 71 patients who underwent radical surgery for rectal cancer were interviewed before and after the operation on their voiding symptoms as subjective parameters and these results were analyzed with objective urodynamic results. Compared with the preoperative voiding symptom score, significant improvement was observed in total voiding symptoms(obstructive plus irritative symptoms) in postoperative sixth month(p 0.05), but residual urine volume was well correlated with overall denervation urodynamic parameters (p < 0.05). In conclusion, postoperative voiding dysfunction was initially deteriorated but was improving over the next six months and better than preoperative status which was explained by removal of irritating tumor focus. The measurement of residual urine volume would be the simple and reasonable method as a substitute for urodynamic study during postoperative voiding dysfunction period.

Giant cell tumor of the spine is regarded as a cllnically mallgnant tumor because of its difficulty in diagnosis, cord compression and its frequent recurrence. The consensus of current report on giant cell tumor is that local resection is the treatment of choice where it is feasible. In the spine, however, because of its inoperable location, irradiation has become an accepted mode of treatment, although the results of which are at best uncertain. Total spondylectomy Is a formidable undertaking and its report is scarce. In 1966, Lievre reported total spondylectomy of the fourth lumber vertebra. In 1968, Stener and Johnsen performed total spondylectomy of three vertebral bodies, the eleventh thoracic through the first lumbar. Recently, in the summer of 1979, Edwards reported prosthetic replacement after total spondylectomy. This report presents our experience with giant cell tumor of the thlrd lumbar vertebra, which was successively treated by an excislonal biopsy through anterior retroperitoneal approach, complete removal of the vertebral body and interbody fusion of the adjoining vertebrae through an anterior medlan transperitoneal approach, and finally by excislon of the remaining posterior elemsnt and a posterior H-graft supplimented by loop wire flxation. At six month follow-up, fusion was solid and there was no exidence of recurrence of the tumor.
