Adrenal and Hepatic Venous Sampling in a Case of Aldosterone-Producing Adrenocortical Carcinoma with Hepatic Metastasis

Background. Adrenocortical carcinoma (ACC) is a rare and highly aggressive malignancy. ACCs often secrete adrenal steroid hormones including cortisol and androgens; however, aldosterone-producing ACC is very rare. Although adrenal production of aldosterone is assessed by adrenal venous sampling, the use of sampling from the relevant vein to assess aldosterone production from a tumor arising from ACC metastasis has not been previously reported. Case Presentation. We report the case of a 69-year-old Japanese man with aldosterone-producing ACC with hepatic metastasis. He presented with a history of treatment-resistant hypertension and hypokalemia. Endocrinological examination showed markedly increased plasma aldosterone concentration and suppressed plasma renin activity. Serum cortisol concentration was not suppressed by administration of dexamethasone 1 mg, and normal circadian variation of cortisol secretion was disrupted. Abdominal computed tomography showed a large tumor in the left adrenal gland and multiple tumors in the liver. Together, these results strongly suggested ACC with multiple liver metastases causing primary aldosteronism and subclinical Cushing syndrome. Adrenal and hepatic venous sampling showed markedly increased aldosterone concentration in the left adrenal vein but no increase in the hepatic vein, despite a pathological diagnosis of ACC with hepatic metastasis, with immunohistochemical investigation showing both primary and secondary tumors to have synthetic capability for aldosterone. The patient received mitotane but declined combination chemotherapy and died 2 months later. Conclusion. This is the first report of adrenal and hepatic venous sampling in a case of aldosterone-producing ACC with hepatic metastasis. The case suggests that hepatic venous sampling is unable to detect aldosterone production from liver metastases arising from ACC

Metastasis of advanced gastric cancer to the extraocular muscle: a case report

Abstract Background Metastatic tumors in the orbit, especially from gastric cancer, are rare. We present a rare case of extraocular muscle metastasis from gastric cancer and raise consideration of metastasis to extraocular muscle as a differential diagnosis of proptosis/lid swelling in a patient with history of malignancy. Case presentation A 54-year-old Japanese woman presented with proptosis, lid swelling, diplopia, and retro-orbital pain in her left eye, which she had been experiencing for 1 day. She had a medical history of poorly differentiated adenocarcinoma of the stomach, which had metastasized to several organs. A computed tomography scan showed enlargement of the medial rectus muscle in her left eye. She was diagnosed as having gastric cancer metastasis to the medial rectus muscle of her left eye, and received a total of 20 Gy radiation therapy to the orbit, which resulted in resolution of her ocular symptoms. She died 3 months after her initial visit to our ophthalmic department. Conclusions Metastasis from malignancy should be considered in the differential diagnosis of a patient presenting with proptosis or lid swelling who has a history of gastric cancer. Radiation therapy of metastases in the orbit may be an effective treatment in such cases

Personalization of Chemotherapy for Metastatic Pancreatic Cancer

Erlotinib is an approved drug for the treatment of advanced pancreatic cancer; however, its survival benefit is small and its cost is high, and the decision to use the drug may often be personalized according to the patient's background. A 72-year-old Asian man in good general condition chose gemcitabine monotherapy over combination therapy with gemcitabine plus erlotinib because the survival benefit of the latter was small. The cost of the drug did not appear to affect this decision. This report details the process of decision making with respect to whether a patient receives targeted therapy, and suggests that the use of molecular-targeted drugs must be personalized from many perspectives, including the patient's social situation
