ABSTRACT
Cisplatin is commonly used as chemotherapy for solid tumors. Its most important side effect is nephrotoxicity, which typically produces a gradual decline in renal function. Acute tubular necrosis is the usual pathological finding, while other findings are rare. A 75-year-old man presented to the emergency department (ED) with diarrhea and hypoglycemia. He was on 5-fluorouracil (5-FU)/cisplatin chemotherapy after a radical total gastrectomy for gastric cancer. Ten days earlier, he had been discharged after the third cycle of chemotherapy with normal renal function. When he arrived in the ED, he had azotemia (creatinine = 9.2 mg/dL) necessitating emergency hemodialysis. His renal function did not recover despite hydration and conservative treatment. Since he could not receive further chemotherapy due to the renal failure, he died 4 months later due to cancer progression. A renal biopsy performed 3 months after the renal failure showed acute tubular necrosis and severe interstitial fibrosis with normal glomeruli suggesting tubulointerstitial nephritis.

A 37-year-old man was referred to Division of Nephrology for a new renal cystic lesion that was found on ultrasonography. Four years prior to presentation, a percutaneous renal biopsy had been performed. Computed tomography scan showed a 4.4-cm-sized renal artery pseudoaneurysm in the left kidney. Selective renal angiography revealed a pseudoaneurysm in the left lower pole of the kidney. The renal pseudoaneurysmwas successfully embolized with coil. Follow-up Doppler ultrasonography showed no internal blood flow into the aneurysmal sac. His renal function remained stable after coil embolization.

Gastric foregut duplication cyst is a rare congenital anomaly. There have been very few reports of bronchogenic cysts in the abdominal cavity attached to the stomach. We report a case of a 57-year-old Korean man with an adenocarcinoma arising within a bronchogenic cyst of the stomach. Pathologic findings revealed ciliated columnar epithelium lining the cyst and a solid papillary adenocarcinoma involving the subserosa of the stomach and the skeletal part of the diaphragm. Surgical resection is the treatment of choice for foregut cysts of the stomach, and the possibility of malignancy should be considered in patients with gastric duplication cysts.

Hyperkalemia is a common adverse effect of treatment for heart failure and is associated with high mortality and morbidity. The cardiac manifestations of hyperkalemia include various electrocardiogram changes. We describe a case of a 74-year-old woman with heart failure and permanent atrial fibrillation who reverted to normal sinus rhythm during recovery from hyperkalemia.

PURPOSE: The aims of this study are to find out whether the sequence of chemotherapeutic regimens including second- and third-line taxane and irinotecan influences the survival of patients with unresectable gastric carcinoma and to identify clinical characteristics of patients with improved response. MATERIALS AND METHODS: Fifty gastric carcinoma patients who were treated by third-line sequential chemotherapy between November 2004 and July 2010 were enrolled in this study. Their overall survival (OS) and time to progression (TTP) were set up as primary and secondary end points. For the sequence of chemotherapy regimen, two arms were used. Arm A was defined as 5-fluorouracil (5-FU)+cisplatin (FP) or folinic acid, 5-FU and oxaliplati (FOLFOX), followed by folinic acid, 5-FU and irinotecan (FOLFIRI), and paclitaxel or docetaxel plus 5-FU, with or without epirubicin. Arm B was defined as FP or FOLFOX, followed by paclitaxel or docetaxel plus 5-FU, and FOLFIRI. RESULTS: The median OS of all patients was 16.0 months (95% confidence interval, 13.6 to 18.3 months), which is longer than historical control of patients who did not receive third-line chemotherapy. The sequence of second and third-line regimen, including irinotecan and taxane, did not present significant difference in OS or TTP after failure of 5-FU with platinum chemotherapy. In survival analysis of patients' clinicopathologic characteristics, poor prognosis was shown in patients with poorly differentiated histologic features, elevated serum carcinoembryonic level, and shorter TTP of first line chemotherapy. CONCLUSION: It is possible for patients to respond differently to chemotherapy due to differences in clinical features and underlying gene expression profiles. Development of individualized chemotherapy regimens based on gene expression profiles is warranted.
