Philadelphia chromosome-positive acute myeloid leukemia (Ph+AML) is a rare disease characterized by a poor prognosis with resistance to standard chemotherapy. We report a patient with Ph+AML with a minor BCR-ABL-positive mRNA transcript who achieved a hematologic, cytogenetic, and major molecular complete response after cytarabine-based chemotherapy followed by imatinib. After more than 6 months of continuous imatinib therapy, the patient is in continuous complete remission. Our results show that imatinib mesylate is effective in treating Ph+AML.

The incidence of coexisting hyperparathyroidism and empty sella syndrome is rare and the etiology and incidence of their coexistence is not known. The association of hyperparathyroidism and the empty sella syndrome may be related to multiple endocrine neoplasia (MEN) syndrome due to a genetic disorder. We experienced a rare case of hyperparathyroidism presenting as acute pancreatitis combined with empty sella. We report here a 37-year old female who manifested epigastric pain because of acute pancreatitis. She had hypercalcemia due to parathyroid adenoma. A pituitary gland was not visible in the sella turcica on MRI scans. On genetic analysis, she did not show a mutation of the MENIN gene. Empty sella is thought to be a coincidental finding with hyperparathyroidism.

Primary retroperitoneal mucinous cystadenocarcinoma is a rare tumor. Only about 30 such cases have been reported in the worldwide literature, and a few Korean cases have been reported. The pathogenesis is not clear, and coelomic metaplasia of the retroperitoneal mesothelium has gained wide support. There is no consensus on the appropriate treatment, but surgical exploration is needed for the diagnosis and treatment, and adjuvant chemotherapy may be recommended following complete surgical excision. The long-term prognosis has not been established. We report here on a 32-year-old woman who was diagnosed as having a retroperitoneal mucinous cystadenocarcinoma with mural nodules of sarcomatoid change. Tumor excision and adjuvant chemotherapy were done and the patient is doing well without any evidence of recurrence at 42 months postoperatively.

BACKGROUND/AIMS: Lung cancer is the leading cause of cancer-related death in Korea. Non-small cell lung cancer (NSCLC) comprises 80~85% of lung cancer. Positron emission tomography with [18F]fluorodeoxyglucose (FDG-PET) shows various levels of FDG uptake for patients with NSCLC. This study determined whether the standardized uptake value (SUV) of FDG uptake by PET is a prognostic factor for advanced NSCLC. METHODS: FDG-PET was performed in 59 patients with stage IIIb and IV NSCLC. The SUV was calculated for each patient. Overall survival (OS) and time to progression were calculated using the Kaplan-Meier method and evaluated with the log-rank test. The prognostic significance was assessed using univariate and multivariate analyses. RESULTS: A cutoff of 7 for the SUV gave the best criminative value. In the univariate analysis, performance status (p=0.02) and SUV (p=0.03) were significant predictors of OS. The patients with low SUVs (< or =7) had significantly better times to progression than those with high SUVs (>7, p=0.04). A multivariate Cox analysis identified performance status and the SUV as important for the prognosis. CONCLUSIONS:These results suggest that SUV is a significant prognostic factor in patients with advanced non-small cell lung cancer.

BACKGROUND AND OBJECTIVES: Atrial septal defect (ASD) is the one of most common congenital heart diseases detected in adults. Along with remarkable development of device technology, the first treatment strategy of secundum ASD has been transcatheter closure in feasible cases. However, there are only a few publications regarding the results of transcatheter closure of ASD in elderly patients, especially those over 60 years of age. We report our results of transcatheter closure of ASD in patients over 60 years old. SUBJECTS AND METHODS: Between May 2006 and December 2011, 31 patients over 60 years old (25 female and 6 male; mean 66.7+/-5.25 years old, range 61-78 years old) were referred to our center. RESULTS: A total of 23 patients underwent therapeutic catheterization to close secundum ASD, and the closure was successful in 22 patients (95.7%). All patients who underwent the procedure survived except for one patient who expired because of left ventricular dysfunction. A small residual shunt was observed in two (9%) of 21 patients before discharge but disappeared at follow-up. All patients eventually had complete closure. There were five patients who had coronary problems. One patient underwent percutaneous coronary intervention using a stent at the same time as transcatheter closure of ASD. Atrial arrhythmias were detected in 6 of 23 patients (26.1%) before the procedure. One patient was successfully treated by radiofrequency ablation before the procedure. No patients displayed new onset arrhythmia during the follow-up period. Follow-up echocardiographic evaluation showed a significantly improved right ventricular geometry. CONCLUSION: We conclude that transcatheter closure of ASD is a safe and an effective treatment method for patients over 60 years old if the procedure is performed under a thorough evaluation of comorbidities and risk factors.
