We describe a modified RIA using a rabbit polyclonal antiserum directed against the first 21 amino acids of the E-domain (E-21) of proinsulin-like growth factor-II (pro-IGF-II). For standardization, we purified big IGF-II from patients with nonislet cell tumor hypoglycemia (NICTH). Under the conditions of our assay there was no significant interference from IGF-binding proteins. The big IGF-II present in the serum of a patient with NICTH displaced [125I]E-(1-21) from antibody parallel to our big IGF-II standard. We found a progressive rise in E-21 immunoactivity (IA) during childhood, with somewhat higher values in girls than in boys. In normal adults the mean E-21 IA level was 138 +/- 49 (+/- SD) micrograms/L. Women with twin pregnancies had higher E-21 IA than women with single pregnancies (302 +/- 66 compared with 120 +/- 18 micrograms/L). We found a marked elevation of E-21 IA in patients with NICTH due to sarcomas (n = 3), hepatoma (n = 2), adrenal carcinoma (n = 1), and carcinoma of the lung (n = 1). No elevation of E-21 IA was present in the serum of a hypoglycemic patient with a hypernephroma or another patient with carcinoma of the lung. Marked elevation of E-21 IA was observed in the serum of patients with renal failure receiving chronic hemodialysis. We conclude that this assay will prove useful in the diagnosis of NICTH in patients who are not azotemic and the investigation of the role of the kidney in clearing products of pro-IGF-II processing.

Diaziquone (AZQ), a synthetic quinone with demonstrated activity against acute nonlymphocytic leukemia (ANLL), primary CNS tumors, and non-Hodgkin's lymphoma (NHL), is virtually devoid of nonhematopoietic toxicity at conventional doses. As a prelude to its inclusion into bone marrow transplant (BMT) preparative regimens, a phase I study of high-dose AZQ with autologous BMT (ABMT) was performed. Patients with refractory solid tumors and lymphomas were treated with a single 24-hour infusion of AZQ at 50 to 355 mg/m2 in dose escalations of 20%. Fifty-six patients received 69 courses. Those receiving greater than 60 mg/m2 had nadir granulocyte and platelet counts less than 500/microL and 20,000/microL, respectively. Nausea, vomiting, stomatitis, and diarrhea were mild, transient, and not dose-related. Transient minimal elevations of liver function tests were seen in five patients and were also not dose-related. The maximally tolerated dose (MTD) of high-dose AZQ was found to be 245 mg/m2, with nephrotoxicity being dose-limiting. Significant azotemia was seen in four of 12 patients treated at 295 and 355 mg/m2, including fatal anuric renal failure in three of these patients. Reversible proteinuria also occurred in 24 of 26 courses above 150 mg/m2, including nephrotic range proteinuria in eight courses, all at doses of 205 to 355 mg/m2. The proteinuria was also associated with multiple proximal tubular defects including generalized aminoaciduria and proximal renal tubular acidosis. There were six early deaths including two of early renal failure (295 and 355 mg/m2), two of sepsis (205 and 245 mg/m2), one of a pulmonary embolus (85 mg/m2), and one of progressive disease (60 mg/m2). Of 50 patients who were assessable for response, there were seven responses including two of 10 with primary CNS tumors, one of 12 with malignant melanoma, one of five with non-small-cell lung carcinoma, two of two with breast carcinoma, and one of one with ovarian carcinoma. Because of its activity in ANLL and NHL and its unique toxicity spectrum, high-dose AZQ may improve the efficacy of current BMT preparative regimens without significantly increasing their nonhematopoietic toxicity.

A prospective study of 26 patients undergoing descending thoracic aorto-iliac/femoral (DTAI/F) bypass was conducted over a 13-year period with an average follow up of 53 months. Reasons for selecting the procedure were occluded aortic bifurcation grafts (9 patients), hostile abdomen (6), infected aortic graft (1), microaorta (10, and surgeons preference in 8 patients who had juxtarenal aortic occlusion. The operative mortality was 3.8% (1 patient). A late mortality of 36% was due to myocardial infarction (1), lung carcinoma (2), renal failure (4), stroke (1) and pulmonary insufficiency (1). Graft failure occurred in 4 patients at 23, 26, 54 and 109 months respectively. Primary cumulative patency was 86% statistically valid at 42 months. DTAI/F bypass is recommended in selected patients when conventional approaches to the aorta are considered unduly hazardous.

A 65-year-old man underwent left-upper lobectomy for large cell carcinoma of the lung on November 8, 1984 (pT1N0M0: Stage I a). He was treated with MMC, Futraful, CDDP and CPM as adjuvant chemotherapy. In April 1985, he was re-admitted to our hospital because of progressive dyspnea. He was diagnosed as having drug-induced interstitial pneumonia, and so steroid therapy was started. In July 1985, he suffered from anemia, thrombocytopenia, proteinuria and azotemia progressively, and died due to pulmonary hemorrhage and edema. At necropsy, no cancer recurrence was found. It thus seemed that the cause of death was microangiopathic hemolytic anemia and renal failure induced by anti-neoplastic agents.

Apudomas are uncommon neoplasms composed of neuroendocrine cells. They include carcinoid tumors, islet cell tumors, and small cell lung carcinoma. We found six cases of apudomas in a series of 1028 renal transplants from three medical centers (0.58%). One of these had been reported in 1976. The cases included a carcinoid tumor of a Meckel's diverticulum discovered and removed prior to transplantation, with no evidence of recurrence 9 years later. A small cell lung carcinoma was discovered 40 months after renal transplantation, with a fatal outcome 6 months later. Four clinically occult apudomas were found at autopsy, including one gastric and one bronchial carcinoid tumor, one multicentric pancreatic islet cell neoplasm, and one case of multiple ileal carcinoids. With the exception of the small cell lung cancer, none of the apudomas was clinically significant, and none was associated with carcinoid or other paraneoplastic syndrome. These cases illustrate the difficulty of diagnosis of apudomas in patients with renal failure and the usually benign nature of these tumors despite the administration of potent immunosuppressive agents.

There are different clinical manifestations and various types of glomerular damages associated to neoplasias. The association to nephrotic syndrome is a relatively frequent event. However, rapidly evolutive renal insufficiency with extensive crescentic glomerulonephritis in more than 50% of the glomeruli is not usually thought to be linked to malignant diseases. We present the case of a previously healthy 55 year old man, who suffered a nephrotic syndrome and renal failure of rapid evolution, in whom a small cell lung cancer was detected. He died in three months and at autopsy mesangial proliferation and enlargement of basal membranes with crescents in 90% of the glomeruli were observed. Electronic microscopy also showed enlargement of the basal membrane. Structures consistent with immune-complex depositions were not seen. We reviewed the reported cases of glomerular lesions and neoplasias, and described the 20 cases published with this particular type of glomerular lesions described for the first time in 1976. None of these 20 cases belongs to this variety of lung cancer. Only in 5 patients, rapidly evolutive renal insufficiency was accompanied by nephrotic syndrome, as in the present case. The presence of immunocomplexes is not frequent and it was mentioned in only four cases. The only three cases of small cell lung carcinoma with nephrotic syndrome described in the literature were associated with membranous glomerulonephritis.

The complication of thrombotic thrombocytopenic purpura or hemolytic uremic syndrome (TTP/HUS) can occur in cancer patients. It is characterized by a microangiopathic hemolytic anemia, severe thrombocytopenia, and renal failure. Pulmonary manifestations, especially pulmonary edema, are a common observation. Neurologic changes are also frequently seen. The etiology is unknown at this time. It has been observed in many different types of cancer and is most commonly seen in gastric adenocarcinoma followed by carcinoma of the breast, colon, and small cell lung carcinoma. The hemolysis can be massive and is due to red cell fragmentation, as schistocytes are present in all the cases. Though immune complexes are present in the plasma, the antiglobulin (Coomb's) test is negative. Chemotherapeutic agents, especially mitomycin C, have been implicated as causative factors. There is a correlation of this complication with the cumulative dose. However, chemotherapy cannot account for all the cases as the syndrome can occur in untreated patients. It can be differentiated from disseminated intravascular coagulation by the absence of a coagulopathy. Management should consist of plasma exchange, use of a Staphylococcus aureus column (Prosorba), and control of hypertension. Because of the susceptibility to pulmonary edema, blood volume overloading should be avoided.

A 66-year-old woman developed rapidly progressive renal failure several days after she was diagnosed with non-small cell carcinoma of the lung. Antineutrophil cytoplasmic antibody test performed as an indirect immunofluorescence assay was positive with a perinuclear pattern of staining (pANCA). The patient did not improve with hemodialysis treatment and died on the second day after admission to the hospital. A complete autopsy was performed and showed metastatic adenocarcinoma of the lung and pauci-immune crescentic glomerulonephritis. A literature search showed only 7 previously reported cases of malignant tumors associated with ANCA-positive pauci-immune crescentic glomerulonephritis. The clinicopathologic findings of the current and all previously reported cases and possible relationship between ANCA-positive glomerulonephritis and malignancy are discussed.

Small cell carcinomas are well-recognized tumors known to occur predominantly in the lung. These neoplasms are occasionally associated with a variety of paraneoplastic syndromes. Four cases of paraneoplastic glomerulopathy associated with small cell lung carcinoma have been reported. However, there have been no reports in the literature indicating an association between endometrial small cell carcinoma and paraneoplastic glomerulopathy. We report a case of neuroendocrine small cell carcinoma of the endometrium associated with membranous glomerulonephritis (MGN), which appeared to be a component of an unusual paraneoplastic syndrome. A 33-year-old multiparous woman presented with abnormal vaginal bleeding and abdominal bloating. Endometrial biopsy revealed neuroendocrine small-cell carcinoma of the endometrium. On the eighth day of hospitalization the patient suddenly developed renal failure. Renal biopsy revealed MGN, probably due to tumor-antigen-related immune complex deposition. Small cell carcinoma of the endometrium may be associated with paraneoplastic MGN. Medical staff should take into account the possibility of a preexisting glomerular injury when managing a patient with small cell carcinoma of the endometrium.

A case of severe hypercalcemia secondary to carcinoma of the lung is described in which hypokalemic alkalosis, renal failure and pancreatitis were also present. The relative importance of the few bone metastases found at autopsy is considered, and a probable endocrine-like effect of the tumour in the development of the hypercalcemia is postulated. Treatment of the hypercalcemia included administration of corticosteroids and disodium EDTA, peritoneal dialysis and subtotal parathyroidectomy; the most effective of these was peritoneal dialysis. Subtotal parathyroidectomy failed to produce a further decrease in serum calcium values. The occurrence of hypokalemic alkalosis in the presence of increased adrenocortical function and its relationship to the carcinoma of the lung are discussed. The possibility that this neoplasm produced two factors which caused systemic effects ordinarily associated with the function of endocrine glands must be considered.
