One hundred and thirty-eight adenocarcinomas of human kidney were assessed histologically with special reference to the tumor malignancy as indicated by the 5-year survival of the patients. Four different grading systems were used; the classification based on the histologic type of tumor growth, the grading of malignancy according to Arner et al., the grading based on the nuclear structure of carcinoma cells and finally a combined grading system based on the nuclear structure and the demarcation of the tumor from the surround tissue. The histologic type of growth was observed to be an inappropriate basis for grading of renal carcinoma. The grading system of Arner et al. was an appropriate method of malignancy grading despite its somewhat low reproducibility. The grading system based on the nuclear structure of the tumor cells was an accurate measure of the intrinsic malignancy of renal carcinoma and gave an excellent correlation between tumor grade and the 5-year survival rate of the patients. The combined grading system was an equally accurate method in estimating the 5-year prognosis of ranal carcinomas and indicated that the poor demarcation of the tumor from the surroundings in an unfavorable prognostic sign.

We reviewed 166 cases of renal cell carcinoma. The presenting symptoms varied from vague backache to hypovolemic shock. The most common symptoms were pain, hematuria, a palpable mass and hypertension. Most cases involved were clear cell carcinoma (83 per cent) and survival was no better than in cases of granular cell carcinoma. The tumors metastasized to almost every organ of the body. Bilateral simultaneous primary renal cell carcinoma is described in 1 patient, who has survived for more than 5 years. The over-all 5-year survival rates of simple and radical nephrectomy were 32 and 66.6 per cent, respectively. Radiation therapy does not improve survival irrespective of stage. The 5-year survival rate with renal vein involvement was 32 per cent. Nephrectomy in patients with distant metastasis did not alter survival. Among the patients with metastasis 74 per cent were dead before 1 year and 96 per cent before 3 years.

A 47-year-old white man in apparent good health had diplopia and swelling of the right upper eyelid. Ocular examination showed proptosis of the right eye, together with a large, pulsatile, collapsible mass simulating a vascular neoplasm and involving the right temple as well as the right upper outer quadrant of the orbit. Biopsy of the orbital tumor disclosed a clear-cell carcinoma compatible with a renal primary tumor; subsequent laboratory examination revealed the offending tumor in the left kidney. Renal carcinomas may metastasize to the globe or to the orbit before the primary tumor is recognized. Pulsatile exophthalmos acquired in middle life associated with significant bone destruction represents a constellation of findings most consistent with a metastatic tumor, probably renal carcinoma, caused by the exceedingly rich vascularization of these metastatic deposits.

A patient was seen with a right upper lobe endobronchial mass initially thought to be brochogenic carcinoma. There was a history of prostatic carcinoma, and subsequent investigation demonstrated a hypernephroma. Thoracotomy and special studies proved the endobronchial metastasis to be prostatic in origin, a rare cause of endobronchial metastasis.

Two long-term tissue culture cell lines and a serially transplantable tumor line growing on nude mice were obtained from a renal cell adenocarcinoma (NC 65). Results of the preliminary characterization of these tumor lines are presented. These data include tumor and cell morphology and growth characteristics in vivo and in vitro. In the nude mouse the tumor matastases to axillary and inguinal lymph nodes. The slow growth rates in culture and in the nude mice as well as the maintenance of the original histologic picture indicate that this tumor still reflects properties of the original carcinoma. Chromosomal analysis proves the human origin of the cell lines.

The first case of primary hyperparathyroidism associated with renal cell carcinoma, nasopharynx carcinoma and thyroid carcinoma is reported. Selective venous sampling with radioimmunoassays for parathyroid hormone was helpful in the differentiation of primary hyperparathyroidism from hypercalcemia associated with malignancy.

The ultrastructure of renal cell carcinoma was studied in 6 patients. This study demonstrated a spectrum of ultrastructural patterns ranging from the classic electron microscopic features of granular cell carcinoma at one extreme, to those of clear cell carcinoma at the other extreme. Other tumors demonstrated intermediate features. There was reasonably good correlation between the light microscopy and electron microscopy. Unusual findings of connective tissue banded structures and basement membrane branching were demonstrated.

The operative or autopsy specimens of 20 cases of renal carcinoma, 10 cases of pancreatic carcinoma and 10 cases of malignant glioma were studied histopathologically and compared with the in vivo angiographic findings. The study was focused on the presence or not of newly formed tumor vessels trying to eludicate if the abnormal vessels seen on angiography are newly formed tumor vessels or altered preexisting vessels.

The primary symptoms and signs, indicating urography, in 369 patients with renal carcinoma have been reviewed. Gross haematuria was noted in 33%, signs of malignancy in 20% and in 13% metastases were first diagnosed. In 15% the renal tumor was an incidental finding at urography performed because of prostatism, cystopyelitis, hypertension and prostatic carcinoma. It is concluded that every urography must have such a high quality as to be able to evaluate the entire urinary system in all patients, as a renal carcinoma may be found at urography in any patient above the age of 30 years.

Cases of adrenal and renal cell carcinoma were reviewed to evaluate vascular origin and architecture. All 9 cases of adrenal carcinoma showed fine, sparse neovascularity. Coarse or at least extensive, neovascularity was demonstrated in 40 of 45 cases of renal cell carcinoma. An analysis of the angiographic features correlated with the known anatomical variations will nearly always enable one to ascertain the origin of the tumor.
