AbstractAbstract PDF
The present study evaluated the clinical implications of adjuvant chemotherapy according to the mismatch repair (MMR) status and clinicopathologic features of patients with intermediate- and high-risk stage II colon cancer (CC).
This study retrospectively reviewed 5,774 patients who were diagnosed with CC and underwent curative surgical resection at Kyungpook National University Chilgok Hospital. The patients were enrolled according to the following criteria: (1) pathologically diagnosed with primary CC; (2) stage II CC classified based on the 7th edition of the American Joint Committee on Cancer staging system; (3) intermediate- and high-risk features; and (4) available test results for MMR status. A total of 286 patients met these criteria and were included in the study.
Among the 286 patients, 54 (18.9%) were identified as microsatellite instability-high (MSI-H) or deficient MMR (dMMR). Although all the patients identified as MSI-H/dMMR showed better survival outcomes, T4 tumors and adjuvant chemotherapy were identified as independent prognostic factors for survival. For the intermediate-risk patients identified as MSI-low (MSI-L)/microsatellite stable (MSS) or proficient MMR (pMMR), adjuvant chemotherapy exhibited a significantly better disease-free survival (DFS) but had no impact on overall survival (OS). Oxaliplatin-containing regimens showed no association with DFS or OS. Adjuvant chemotherapy was not associated with DFS in intermediate-risk patients identified as MSI-H/dMMR.
The current study found that the use of adjuvant chemotherapy was correlated with better DFS in MSI-L/MSS or pMMR intermediate-risk stage II CC patients.

AbstractAbstract PDF
Retroperitoneal fibrosis (RF) is a disorder characterized by the presence of a retroperitoneal mass and concurrent systemic inflammation. Some cases of RF are recognized as belonging to the spectrum of immunoglobulin G4-related disease (IgG4-RD). Glucocorticoids are highly effective for treatment of retroperitoneal fibrosis, although the optimal dose and duration of therapy have not been established. An initial dose of prednisone (40-60 mg) daily is usually administered with a tapering scheme. We report on a 55-year-old man diagnosed with IgG4-related RF and successfully treated with a 3-day course of daily 250 mg (4 mg/kg) intravenous methylprednisolone, which resulted in the prompt resolution of urinary obstruction and systemic symptoms.
