From the Scandinavian Sarcoma Group Register, information on 1,224 surgically-treated patients with soft tissue sarcoma (STS) of the extremity or trunk wall, diagnosed between 1987 and 1995, was collected. 205 patients, one third of whom were referred to a center with a local recurrence, had a total of 284 local recurrences. This analysis describes the treatment for these local recurrences, compli

We report the outcome in 32 patients operated on for advanced periacetabular metastatic destruction, where all but 2 had Harrington class III destruction. The patients were operated on using the Harrington reconstruction technique, where threaded pins and cement and a total hip replacement are used to reconstruct the acetabulum and ilium. The median survival was 11 (0-106+) months. 13 patients liv

We analyzed treatment and outcome in 104 Scandinavian patients with synovial sarcoma in the extremities or trunk wall, diagnosed between 1986 and 1994. Only surgically treated patients without metastases at diagnosis were included. Median follow-up of survivors was 6 (3-11) years. 34 patients developed metastases. The overall 5- and 7-year survival rates were 0.76 (95% Cl 0.66-0.83) and 0.69 (0.58

Aneurysmal bone cyst (ABC) is a benign bone lesion for which no previous cytogenetic data exist. We describe the finding of clonal chromosome aberrations in three tumors; two had a t(16;17)(q22;p13) as the sole anomaly, and the third had a del(16)(q22) as the only change. These findings show that somatic mutations contribute to the development of ABC and furthermore indicate that bands 16q22 and 1

The local and systemic invasiveness of soft-tissue sarcomas may depend upon an interaction between the primary tumour and the extracellular matrix in which the proteolytic enzyme, urokinase plasminogen activator (uPA), may have an important role. We analyzed the expression of uPA in soft-tissue sarcoma using a luminescent immunoassay technique; and examined the relationships between different uPA

Abnormal patterns of proliferation characterize the behavior of many tumors. Proliferating cell nuclear antigen (PCNA) and Ki‐67 are two cell cycle antigens which are expressed in proliferative states. Our study examines the prognostic value of these cell‐cycle antigens in soft tissue sarcoma (STS). Paraffin‐embedded primary tumor tissues from 185 patients (1980–92) were stained with the anti‐PCNA

Our study combined size and timing of the first local recurrence to create a growth rate index (GRI- ratio of size (cm) to timing (mo)) which we analyzed for an association with metastasis. We analyzed 134 locally recurrent tumors from a series of 460 adult patients with soft tissue sarcoma of the extremities and trunk wall who were diagnosed and treated between 1964 and 1990, with a median follow

We analyzed the quality of surgery In a population-based series of 375 patients with primary soft tissue sarcoma of the extremity (n 329) and trunk wall (n 46). the quality was measured as the total number of operations performed for the primary tumor-biopsy, excision, reexcision-and the local recurrence rate. A comparison was made between patients referred to our tumor center before surgery (n 19

Grading based on histopathologic features is used to predict survival in soft‐tissue sarcoma. However, variations in clinical behavior between tumors of the same grade motivate a search for additional factors that correlate with prognosis. Proliferating cell nuclear antigen (PCNA) is expressed in proliferating cells during the G 1 S and G 2 ‐phases. To evaluate a prognostic implication of PCNA, t

We analysed metastasis-free survival after local recurrence in a population-based series of 432 patients treated for soft-tissue sarcoma of the extremities or trunk wall. Local recurrence was found in 124 patients; of these, 73 had no detectable metastases when the last local recurrence was diagnosed. No patient received chemotherapy for local recurrence. The 73 patients had a 5-year metastasis-fr

Fifty-one patients with deep-seated soft tissue sarcoma of the extremities and trunk wall were examined with contrast-enhanced CT for presence of nonenhanced tumor areas (CT necrosis). After a median follow-up time of 3 years, 19 of the 41 patients with CT necrosis had developed metastases, compared to none of the 10 patients who had tumors without CT necrosis. Tumors with CT necrosis were larger

Epidemiology and prognosis were analyzed in a consecutive, population‐based series of 137 patients with malignant fibrous histiocytoma of soft tissue in the extremities and trunk wall, with a complete follow‐up of minimum 3 years. All but one patient were treated by surgery in 28 cases combined with adjuvant radiotherapy or chemotherapy. The annual incidence was 0.42/105. The ratio men to women wa
