No improvement in the overall survival of 194 patients with chondrosarcoma in Finland in 1971-1990.

We describe the clinicopathologic profile and survival of 306 patients with chondrosarcoma reported to the Finnish Cancer Registry in 1971-1990. 218 cases were available for reevaluation. Owing to their various clinicopathologic characteristics, we excluded the histologic variants of chondrosarcoma.

Molecular profiling of human chondrosarcomas for matrix production and cancer markers.

Chondrosarcoma is the second most common malignant bone tumor, characterized by production of abundant extracellular matrix resembling hyaline cartilage. To better understand the molecular pathogenesis of chondrosarcoma, we analyzed 12 chondrosarcomas for their production of connective tissue components and SOX9, a key regulator of normal chondrocyte differentiation. Furthermore, 10 chondrosarcoma samples were screened for additional changes in gene expression using cDNA array analysis.

Leiomyoma of the urinary bladder.

We report a case of rare benign bladder leiomyoma. The patient was a 42-year old man complaining impotence. Digital rectal examination revealed a palpable pelvic tumor.

Dynamic contrast-enhanced MR imaging and MR-guided bone biopsy on a 0.23 T open imager.

Objective: To assess the feasibility of MR (magnetic resonance)-guided bone biopsies.

Design And Patients: Thirty-six consecutive patients with known or suspected benign or malignant bone lesions underwent comprehensive MR imaging. A dynamic contrast-enhanced sequence followed by stationary T1-weighted sequences were obtained and MR-guided bone biopsy of the tumor at the site with fastest enhancement was performed using an open 0.
