Article Abstract

Objective: To explore the pathoclinical features of adult primary mediastinal liposarcoma and their correlation with the prognosis.

Methods: The clinical data of 19 patients with adult primary mediastinal liposarcoma who were treated in our hospital between 1970 and 2011 were retrospectively analyzed. Eighteen patients underwent open thoracic tumor excisions for at least one time, and the remaining one patient only received biopsy surgery. Histopathological results after surgery revealed that 6 well-differentiated type tumors, 6 myxoid type tumors, 3 pleomorphic type tumors, 2 mixed type tumors, and 2 un-classified tumors.

Results: Among 6 patients with well-differentiated type tumors, 1 died after having been survived for 10 years; 5 were still alive, with a mean duration of 126.2 months,the 5-year survival rate was 100%. Among 6 patients with myxoid type tumors, 5 patients had follow-up data, with a mean survival of 26.2 months. Among 3 patients with pleomorphic type tumors, only one patient had follow-up data: the patient finally died, with a survival of 34 months. Of 2 patients with mixed type tumors, only one patient had follow-up data: the patient survived 8 months and died. Of 2 patients with un-classified type tumors, one had follow-up data: the patient lived for 24 months and died.

Conclusions: Mediastinal liposarcoma is a rare disease. Surgery is the primary therapeutic modality. Different pathological subtypes have different epidemiological features, biological behaviors, and malignant potentials. Pathological subtype is an important prognosis factor. Patients with well-differentiated tumors have much better prognosis than those with other subtypes.
