Debulking surgery for advanced thymoma.

AIMS: This study was conducted to evaluate the efficacy of debulking surgery in the treatment of locally advanced but operable malignant thymoma. METHODS: We reviewed 43 cases with incompletely resected stage III and IVa malignant thymoma managed between January 1987 and December 2002. RESULTS: Twenty-two had stage III and 21 had stage IVa disease. Maximal debulking was performed in 15 patients, nine with stage III and six with stage IVa disease. Nine patients also had myasthenia gravis (MG). Using univariate Kaplan-Meier analysis, we found that maximal debulking surgery, RT, and with the presence of MG were associated with better survival. Debulking resulted in a better outcome than non-debulking surgery (mean survival: 106 months vs 57.2 months). After adjustment with multivariate analysis, RT and MG were both associated with better survival. CT did not appear to be beneficial for advanced thymoma. CONCLUSIONS: RT is independently associated with a better outcome in locally advanced thymoma. Debulking surgery apparently allows for a better response to RT.

Idiopathic inflammatory myopathy with diffuse alveolar damage.

Interstitial lung disease (ILD) in patients with myositis is defined by the presence of interstitial changes on radiographic examination. The reported prevalence of ILD varies from 0% to nearly 50%. However, only rarely has the pathological pattern of diffuse alveolar damage (DAD) associated with idiopathic inflammatory myopathy (IIM) been reported. We report five patients with IIM (one with dermatomyositis, one with polymyositis, and three with amyopathic dermatomyositis) and respiratory failure. Four underwent open lung biopsy with pathological proof of diffuse alveolar damage (DAD). Despite intensive immunosuppressive therapy, all of them died. In addition to the case reports, we discuss DAD in patients with IIM.

Recurrent retroperitoneal myxoid liposarcoma during pregnancy: a case report and literature review.

Retroperitoneal liposarcoma in pregnancy is rare, and only a few cases of primary liposarcoma during pregnancy have been reported. To the best of our knowledge, there is no published report of retroperitoneal liposarcoma that was previously treated and recurred during pregnancy. Our patient was diagnosed with a pelvic mass on ultrasound at 12-weeks' gestation. The mass was found to be a retroperitonal, well-differentiated myxoid liposarcoma and was radically excised at the time of cesarean delivery at 36-weeks' gestation. However, the tumor recurred soon and progressed rapidly, and the patient eventually died of the disease. A thorough sonographic investigation and timing of surgery may be critical in terms of finding a surgically resectable lesion and leading to a more favorable prognosis.
