This report describes the clinical and biochemical features of 30 cases of ectopic ACTH-producing tumors diagnosed by the detection of ACTH in the tumor tissues. Several uncommon tumors, such as tumors of the esophagus, stomach, and larynx, were included in this series. None of the patients with bronchogenic carcinoma showed signs of classical Cushing's syndrome, whereas 7 of the remaining 13 patients with other tumors were Cushingoid in appearance. Adrenocortical hyperfunction was present in 61 percent at the first examination and developed during the course of the disease in 18 percent more. In the remaining patients (21 percent), adrenocortical function remained within normal limits. These results indicate that there exist ectopic ACTH-producing tumors without clinical and biochemical sequelae of excess hormone. In some of the tumor extracts studied, MSH and CRF-like activities and serotonin were detected. This suggests that multiple hormone production is not uncommon in ectopic ACTH-producing tumors.

A 36-year-old man with depression, Cushingoid features and hypogonadism was found to have simultaneous pituitary-dependent Cushing's disease and marked elevation of serum prolactin (PRL). CT-scan revealed a macroadenoma with suprasellar extension. Transphenoidal surgery cured the patient's Cushing's disease, but failed to correct his hyperprolactinemia, which was controlled by subsequent bromocriptine therapy. Immunostaining of the pituitary tumor was positive for PRL as well as for ACTH, and ACTH-related peptides beta-lipotropin and beta-endorphin in two distinct tumor cell lines. This pituitary tumor is one of the few mixed PRL- and ACTH-secreting tumors documented by immunostaining. It is the second reported in a macroadenoma, in which PRL-secreting tumoral cells are much more abundant than ACTH-secreting cells.

Between 1981 and 1986, 126 patients with diffuse large cell lymphoma were treated with MACOP-B (methotrexate/doxorubicin/cyclophosphamide/vincristine/prednisone/bleomy cin). All had advanced-stage lymphoma (Ann Arbor stage III or IV or stage I or II if the tumor mass was greater than 10 cm or B symptoms were present). The complete response (CR) rate was 84% and the toxic death rate was 6%. Actuarial overall survival at 3 years was 67% and at 8 years 62%; the failure-free survival at 8 years was 52%. The follow-up for MACOP-B is 39 to 106 months (median 76) for living patients. A multivariate prognostic factor analysis for this group of patients identified age greater than 60 years. B symptoms, more than one extranodal site of disease, and more than three nodal sites of disease as the four significant prognostic variables. From June 1986, 108 patients were enrolled on a modification of MACOP-B called VACOP-B (etoposide/doxorubicin/cyclophosphamide/vincristine/prednisone/bleomycin ). Their CR rate was 81%, and the toxic death rate was lower, at 3%. The 60% overall survival at 3 years is not statistically significantly different from that of MACOP-B. The incidence of moderate or severe mucositis and Cushingoid changes was much lower with VACOP-B. The MOPP/ABV (mechlorethamine/vincristine/procarbazine/prednisone- doxorubicin/bleomycin/vinblastine) hybrid chemotherapy regimen for advanced-stage Hodgkin's disease was standard therapy from April 1981 to June 1988 for untreated patients aged 16 to 65. Advanced stage was defined as stages IIB, IIIB, III2A, IVA, IVB, or stages IIA or IIIA with greater than four splenic nodules or a mediastinal mass greater than one third of the transthoracic diameter.(ABSTRACT TRUNCATED AT 250 WORDS)

Six cases of adrenal cortical tumors are presented with a discussion of the clinical features and histological findings. Five of the 6 children, aged between 6 mths and 6 yrs, presented with symptoms of hyperadrenalism, 4 with virilization and 1 with Cushingoid features. The remaining infant presented with an asymptomatic abdominal mass. In each case there was a unilateral tumor separated from the residual adrenal gland by a thin fibrous capsule. Surgical resection was the treatment employed and, in the 5 cases with functional tumors, perioperative hydrocortisone was given. None of the children received post-operative chemotherapy or radiotherapy. Bizarre cellular morphology, a high mitotic count and extensive necrosis were all seen in clinically benign disease, demonstrating not only the efficacy of local resection but also the difficulty in applying the usual histological criteria of malignancy to these pediatric adrenal tumors. At follow-up, 5 of the 6 patients are alive with no evidence of recurrent disease. The only death resulted from measles pneumonitis in the 1 child who presented with Cushing's syndrome.

A 42-year-old female was admitted to our hospital with a chief complaint of hypertension. Endocrinologically, the plasma cortisol level was increased, but its diurnal rhythm had disappeared and the plasma cortisol level was not suppressed by dexamethasone loading at 2 mg or 8 mg. The plasma ACTH level was low. Computerized tomographic scan, echography and adrenocortical scintigraphy showed an adrenocortical tumor on the right adrenal gland. Physical examination did not reveal typical Cushingoid symptoms such as moon face, central obesity and violaceous striae. Thus we diagnosed this case as non-Cushingoid Cushing's syndrome and performed right adrenalectomy. Histological examination showed adreno-cortical adenoma without malignancy.

The efficacy and side-effects of megestrol acetate and medroxyprogesterone acetate in postmenopausal patients with advanced breast cancer were compared in a prospectively randomized study. The dosage of MA was 2 X 80 mg p.o. or MPA 2 X 500 mg p.o. daily, given as a secondary hormonal treatment, mostly after previous treatment with tamoxifen. Ninety-eight patients entered the study and 92 were evaluable for effect, 48 patients on MA and 44 on MPA. Age, main tumor site and prior treatment were not different, but there was a preponderance of ER-negative tumors in the MA group. Responses appeared to be more frequent in the MPA-treated group (25% vs. 43%), predominantly in bone lesions, 12% for MA and 45% for MPA. Median progression-free survival was comparable, 15 vs. 10 months, and overall survival was not different (20 vs. 16 months). Toxicity was frequent, occurring in 83% vs. 74% of patients: increased appetite, nausea and dizziness in more than 20%, and a preponderance of pyrosis and breathlessness on MA and hot flashes, sweating and tremors on MPA. Cushingoid symptoms were present in about a quarter of the patients treated for more than 3 months. The occurrence of thrombo-embolic episodes and cardiovascular events was evenly distributed. Patients on MPA had more often increase in body weight, systolic blood pressure and serum creatinine than those treated with MA. It is concluded that MPA may be more effective for treatment of bone metastases, at the expense of more progestational side-effects. The occurrence of Cushingoid effects is frequent but similar in both arms, while the incidence of cardiovascular or thrombo-embolic events cannot be related to the use of either compound.

In 47 postmenopausal women with evaluable breast cancer, oral medroxyprogesterone acetate (MPA) was given at a daily dose level of 400 mg. Patients with negative estrogen receptors, poor performance status, or nonresponse to previous endocrine therapy were excluded from this study. There were 25 (53%) responders to this agent. Periods of remission ranged from 5-26 months with a median of 10 and a mean of 12+ months. Higher rates of response were noted in women over 50 years of age, in patients with osseous metastasis, and in patients with a longer disease-free interval. Adverse effects included weight gain, Cushingoid appearance, skin rash, and vaginal discharge. In this selected group of patients, oral medroxyprogesterone at a dose level of 400 mg/day appeared to provide a significant frequency of tumor response.

A 28 year old white women was found to have a cervical tumor in the 25th week of pregnancy. Pathologic examination revealed a nonkeratinizing small cell carcinoma. After delivery by cesarean section, pelvic lymph node exploration was carried out, and all 15 nodes were free of tumor. Her condition was staged as II-A, and she was treated with local radiation. Metastatic disease became manifest almost a year later and was histologically similar to her primary disease. A Cushingoid appearance was noticed and plasma cortisol levels were elevated. Twenty-four hour urinary 17-hydroxycorticosteroid (17-OHCS) and 17-ketosteroid (17-KS) levels were elevated and failed to suppress with dexamethasone. Plasma adrenocorticotropin (ACTH) level was elevated. Electron microscopic examination of the tumor tissue revealed neurosecretory granules. Immunoperoxidase stains for ACTH were positive. The patient's course was one of progressive decline and eventual death. A literature review revealed two other cases in which carcinoma of the uterine cervix was considered to be the source of ectopic ACTH. Some small cell carcinomas of the cervix may arise from cells of the APUD series. Small cell carcinoma of the uterine cervix may behave differently from the more commonly encountered keratinizing and large cell nonkeratinizing carcinomas of the cervix and may not respond as well to standard therapy. Ectopic hormone production, production of abnormal peptides or of vasoactive amines may be more common in small cell carcinoma of the cervix than is currently recognized, and these products may be clinically useful as tumor markers.

A patient is described with Cushingoid features and a tumor of the paranasal sinuses. Laboratory studies revealed hyperglycemia, hypokalemia, alkalosis, hypercortisolemia, and elevated serum ACTH levels. The cortisol level increased briskly in response to parenteral ACTH, but was only partially suppressed by dexamethasone. Microscopically, the tumor was found to be a paraganglioma containing many neurosecretory granules.. Treatment with methyrapone, o,p'DDD, and irradiation of the tumor resulted in a lasting remission. It is concluded that this unique patient suffered from Cushing's syndrome due to ectopic ACTH production by a paraganglioma of the paranasal sinuses.

We report a case of a 58-year-old man with adrenal medullary hyperplasia associated with cortisol producing adenoma. Preoperative examination showed both adrenocortical and adrenomedullary hyperfunction. No Cushingoid sign was present and pheochromocytoma-like symptoms were predominant. Abdominal computerized tomography revealed a left adrenal tumor stained by contrast medium. Histologically, the adrenal tumor was found to be a cortical adenoma, and medullary hyperplasia was observed in the remaining parenchyma.
