Case Report Solitary Adrenal Metastasis from Esophageal Adenocarcinoma: A Case Report and Review of the Literature

Introduction. In patients with extra-adrenal malignancy, an adrenal mass necessitates investigating the possibility of metastatic tumor. Curable adrenal metastasis are considered as a rare event. Case report. A 52-year-old male suffering from lower esophageal adenocarcinoma with a solitary left adrenal metastasis is presented herein, who underwent concomitant transhiatal esophagectomy and left adrenalectomy. The patient remains disease-free 18 months later. Discussion. Adrenal metastases mostly occur in patients with lung, kidney, breast, and gastrointestinal carcinomas. Primary esophageal adenocarcinoma gives adrenal metastatic deposits according to autopsy series with an incidence of about 3%-12%. When no other evidence of metastatic disease in cancer patients exists, several authors advocate adrenalectomy with curative intent. Isolated cases of long-term survival after resection of solitary adrenal metastasis from esophageal adenocarcinoma, like in our case, have been reported only as case reports. Conclusion. This study concludes that surgical resection may result in survival benefit in selected patients with solitary adrenal metastasis from esophageal adenocarcinoma

Acute-phase response patterns in isolated hepatic perfusion with tumour necrosis factor α (TNF-α) and melphalan in patients with colorectal liver metastases

Background. In this study, we have evaluated hepatotoxicity, secondary cytokine production and hepatic acute-phase response (APR) in patients who underwent isolated hepatic perfusion (IHP) with tumour necrosis factor (TNF) α and melphalan for irresectable colorectal liver metastases. Design. An extracorporeal veno-venous bypass was used to shunt blood from the lower body and intestines to the heart. Inflow catheters were placed in the hepatic artery and portal vein, and an outflow catheter in the inferior caval vein. The liver was perfused for 60 min with 0.4 mg of TNF-α plus 1 mg kg-1 melphalan (IHP(TM) group, n = 6) or 1 mg kg-1 melphalan (IHP(M) group, n = 3). The liver was washed with macrodex before restoring vascular continuity. Results. After the washout procedure, a TNF-α peak (169 ± 38 pg mL-1) was demons
