Hyperadrenocorticism was diagnosed in 7 cats with concurrent diabetes mellitus. Four cats had pituitary adenoma with bilateral adrenocortical hyperplasia, 1 cat had pituitary carcinoma with bilateral adrenocortical hyperplasia, 1 cat had adrenocortical carcinoma, and 1 cat had adrenocortical adenoma of the left adrenal gland. One year later, adrenocortical adenoma involving the right adrenal gland also was diagnosed in this cat. Clinical signs included polyuria and polydipsia (n = 7), development of pot-bellied appearance (n = 5), dermatologic alterations (n = 5), lethargy (n = 3), weight loss (n = 3), dyspnea/panting (n = 2), and recurrent bacterial infections (n = 2). In 6 cats, the diagnosis of hyperadrenocorticism was established before death on the basis of results of the ACTH stimulation test (n = 3) and the dexamethasone screening test (n = 5). Pituitary-dependent hyperadrenocorticism was differentiated from adrenocortical neoplasia on the basis of results of the dexamethasone suppression test (n = 4), endogenous ACTH concentration (n = 3), results of abdominal radiography and ultrasonography (n = 3), and exploratory celiotomy (n = 1). Four cats died or were euthanatized without treatment attempts. Treatment with mitotane followed by 60Co teletherapy was ineffective in one cat with pituitary adenoma. One cat with pituitary carcinoma died one week after bilateral adrenalectomy. Bilateral adrenocortical adenomas were removed surgically in the affected cat.

A case of a huge inoperable adrenocortical carcinoma which secreted testosterone without characteristic symptoms was treated with o,p'-DDD (2,2-bis(2-chlorophenyl-4 cholorophenyl) 1,1-dichloroethane). With this therapy, the tumor decreased in size which was confirmed by the computed tomography (CT). Eighteen months later, however, lethargy and logopathy appeared and the tumor grew again rapidly with the withdrawal of o,p'-DDD performed for the evaluation of these mental disturbances. The tumor then diminished gradually in size soon after the treatment was resumed and the above unfavorable symptoms were not developed again with the combined administration of a central nervous stimulant. During o,p'-DDD treatment, plasma testosterone and estrogen decreased, and plasma aldosterone also decreased but within the normal range. Plasma cortisol also tended to decrease despite hydrocortisone was administered. Plasma adrenocorticotropic hormone (ACTH) was maintained within the normal range for the first six months but then increased gradually. It decreased and became normal with the additional administration of hydrocortisone. The patient's normal menstruation at the preadministrative stage changed to oligomenorrhea, then amenorrhea after the treatment, but no endocrinological sign except for the menses was observed during the treatment.

Naturally-occurring hyperadrenocorticism was diagnosed in an 11-year-old female Dachshund with signs of polydipsia, polyuria, pendulous abdomen, weakness, depression and lethargy, and laboratory test abnormalities comprising lymphocytopaenia, eosinopaenia, hypercholesterolaemia and increased plasma alkaline phosphatase concentration. While awaiting hormonal test results, an adrenocorticolytic drug (o,p'-DDD) was administered for 14 days, during which the patient deteriorated. Hormonal assays suggested a functioning adrenocortical tumour, but the poor condition of the patient precluded adrenalectomy. An adrenocortical carcinoma with hepatic metastases was found at necropsy.

To study the biologic behavior and natural history of this rare but challenging tumor faced by oncologists, a clinicopathologic study of 42 patients with histologically proven adrenal cortical carcinoma from Roswell Park Memorial Institute (1929--1977) was done. These constituted .04% of all cancer cases and 0.2% of all autopsy cases. Age range was 3--74 years with median of 53 years; female to male ratio was 1.5 to 1. Clinical manifestations were: abdominal mass (36%), metastatic disease (30%), hormonal excess (17%) and weakness with lethargy (17%). Nine of ten functioning tumors were seen in female patients. Tumors arose in left adrenal in 26 patients, right adrenal in 12, and in four the site could not be determined because of bilateral presence of cancer. Median duration of symptoms was six months. At diagnosis, 52% had distant metastases, 41% had locally advanced tumor and 7% had tumor confined to adrenal. Sixteen patients underwent "curative" resection. Tumor diameter ranged from 1--30 cm with median of 10 cm. Of 28 patients who received different chemotherapeutic regimens, three (11%) had objective response; four of ten patients had objective response to radiation therapy. Overall median and five-year survival rates were 14 months and 24%. Prolonged survival (P less than .05) was noted in women, patients who had "curative" resection, a disease-free interval of more than 12 months, and tumor size greater than 10 cm diameter. Patients with functional tumors had longer median survival than those with non-functional ones (28 vs. 12), but P value was greater than .05. A second primary cancer was noted in 22.4% of cases, breast and lymphoma being the most common. At autopsy in 31 patients, the most common metastatic sites were retroperitoneal lymph nodes 68%, lung 71%, liver 42%, and bone 26%. To improve survival, an aggressive surgical approach is recommended to extirpate the tumor with involved organs and retroperitoneal lymph nodes. Adrenal carcinoma should be suspected in patients with metastatic cancer with an occult primary.
