Thirty-one patients with locally extensive and metastatic renal cell carcinoma were observed over an eight year period. At onset of the disease, symptoms due to metastatic deposits were the most frequent mode of presentation, followed by manifestation of local tumor growth (hematuria, flank pain or palpable mass) and paraneoplastic syndromes. Hormonal therapy with testosterone propionate, a progestational agent or both was assessed in 21 cases. Five instances of tumor regression, two involving recalcification of lytic osseous metastases, were documented. Endocrine studies to elucidate possible mechanisms of hormonal effectiveness were carried out in seven cases. Median survival from diagnosis was ten months. Following the rapid early mortality, a very gradual decrease in survival occurred, with 25% alive at ten years. Factors influencing survival include the duration of the interval between diagnosis of the primary tumor and appearance of metastases and the association of certain paraneoplastic syndromes.

A case of primary osteogenic sarcoma of the kidney is presented. The patient, a 75-year-old man, presented with flank pain, weight loss, and a lower lip lesion. Biopsy of the lip lesion showed metastatic sarcoma and nephrectomy revealed a primary osteogenic sarcoma. Ultrastructural and immunohistochemical studies confirmed the mesenchymal nature of the lesion and helped exclude sarcomatoid renal cell carcinoma from the differential diagnosis. Multiple samples of the primary tumor and metastatic deposits analyzed by DNA flow cytometry all showed a diploid DNA content. Clinically the tumor has pursued a slowly progressive course, with metastases.

Renal cell carcinoma (RCC) is a relatively uncommon cancer in renal transplant patients. From 1968 to 1987, 101 cases of RCC of native kidneys have been reported to the Cincinnati Transplant Tumor Registry. We describe here a case of metastatic RCC associated with acquired cystic kidney disease (ACKD) 15 years after successful renal transplantation. The patient presented with a subcutaneous nodule, which led to discovery of a large primary tumor in the left kidney. ACKD was present in the atrophic right kidney. The reported cases of ACKD-associated RCC in renal transplant recipients were reviewed. Most of these cases are middle-aged men with a long posttransplant course, good graft function, and usage of azathioprine and prednisone as immunosuppressive agents. ACKD can develop or persist and progress to RCC many years after successful renal transplantation. Transplant patients with flank pain, hematuria, or other suspicious symptoms should have imaging studies of their native kidneys.

The success of cancer therapy depends on the destruction of all viable cancer cells in the primary site, as well as in metastatic areas. Surgery alone can do little for the patient whose tumor has produced distant involvement except in those situations where surgical excision, radiotherapy, chemotherapy, or immunotherapy can be relied on to eradicate metastatic disease. Because of the paucity of systemic therapy for renal cell carcinoma, an aggressive surgical approach to the primary tumor is justifiable when all metastatic lesions can be excised or otherwise definitively treated and in experimental protocols in which adjuvant therapy of possible benefit can be combined with palliative nephrectomy. There is no evidence, however, in reported studies to suggest that routine palliative nephrectomy in patients who will not be offered adjuvant systemic therapy or radiation is beneficial. Such practice is also associated with a higher incidence of complications and mortality than is expected for resection of localized renal cell carcinoma. For these reasons, it is reasonable to recommend adjunctive nephrectomy only in certain selected instances, which include (1) the control of a patient's current symptoms related to the primary disease, for example, flank pain, hematuria, fever and toxicity, anemia, erythrocytosis, and hypercalcemia; (2) nephrectomy with the excision of a solitary metastasis; and (3) the patient who is willing to undergo experimental therapy, part of which involves removal of the primary tumor.

Thirty-four cases of tumor of the renal pelvis or ureter or both have been treated in our department during the past decade. The primary tumor was in the renal pelvis in 11 cases, in the ureter in 21 cases and in the ureter and renal pelvis in 2 cases, a co-existent tumor in the bladder was found in 4 cases. Seventeen patients had a tumor on the right side and 17 on the left side. The most frequent symptom was gross hematuria (70.6%) and flank pain was the presenting symptom in 7 cases (20.6%). On the intravenous pyelography, a filling defect in the renal pelvis or ureter (41.2%) and nonvisualization (53.0%) were frequent findings. Twenty-nine cases had undergone total nephroureterectomy with resection of a bladder cuff, 3 had simple nephrectomy and 2 had open biopsy alone. Postoperative radiation therapy was done in 1 case, chemotherapy in 10 cases, and 6 cases of them were treated by CAP therapy (cis-dichlorodiamine platinum, doxorubicin and cyclophosphamide). Actual and relative 5-year survival rates were 53.8% and 63.5%, and no significant difference was found in survival rate between the patients with renal pelvic tumors and those with ureteral tumors.

Leiomyosarcoma of the left kidney seen in a 58-year-old man is reported. On April 10, 1982, he complained of left flank pain. He visited our hospital and left solitary renal cyst was suspected. He had been treated as an outpatient, but left flank pain became exacervated. On May 18, he was admitted to our hospital. On June 7, radical nephrectomy was done under the diagnosis of left renal cell carcinoma. At operation, the tumor invased directory to the psoas muscle and abdominal wall, and could not be completely resected. Pathological diagnosis was renal cell carcinoma with sarcomatoid change. On July 1, he was discharged from the hospital. In December, left flank distention appeared and back pain became exacervated. On February 8, 1983, he was readmitted to our hospital. Low density area was found in left psoas muscle by CT scanning and recurrence of renal cell carcinoma was suspected. alpha-Interferon therapy had been done, but tumor increased remarkably and caused ileus. He died on June 14, 1983. The autopsy revealed a child head-sized cystic tumor in the upper retroperitoneal space, a 5 X 5 X 5 cm metastasis of the left lobe of the liver, a 3 X 3 X 4 cm tumor to the left upper lobe with cavity formation and direct invasion into the spleen, diaphragma and gastric serosa. These metastatic lesions were leiomyosarcoma. Retrospectively, the primary tumor of kidney revealed primary leiomyosarcoma of kidney.

Primary malignant tumors of the aorta are rare, only a handful of isolated cases having been described in the literature. Preoperative diagnosis of these tumors is more the exception than the rule. Diagnosis of aortic tumors is difficult as they can mimic many diverse conditions including atherosclerosis. We report a patient who presented with lower extremity claudication, renal infarction, and diffuse atherosclerosis and who was found to have tumor fragments in blood clots but no evidence of a primary tumor. Immunohistochemistry narrowed the differential diagnosis to a type of sarcoma. Six months later, he developed right flank pain due to a malignant fibrous histiocytoma that involved the abdominal aorta and that had initially manifested as tumor emboli.

We report a case of a sonographically-detected impalpable embryonal cell carcinoma with bulky retroperitoneal metastases. A 34-year-old man, who presented with left flank pain, was presumed to have an extragonadal retroperitoneal germ cell tumor. Scrotal sonography revealed a hypoechoic lesion, 7 mm in diameter, which was histologically diagnosed as a primary embryonal cell carcinoma. Evidence suggested that the primary tumor had grown slowly, as the tumor was well encapsulated. This case suggests that some extragonadal germ cell tumors arise from a primary testicular cancers, and that successful treatment of these tumors should include consideration that they may have arisen as a primary testicular mass.

Ewing's sarcoma/primitive neuroectodermal tumor (ES/PNET) is an extraordinarily rare primary tumor in the kidney and can be mistaken for a variety of other round cell tumors, including blastema-predominant Wilms' tumor (WT). Approximately 90% of ES/PNET have a specific t(11;22), which results in a chimeric EWS-FLI-1 protein. Immunohistochemistry for the carboxy-terminus of FLI-1 is sensitive and highly specific for the diagnosis of ES/PNET. WT-1, the WT-associated tumor suppressor gene, is overexpressed in WT but not in ES/PNET. No study has examined FLI-1 or WT-1 expression in renal ES/PNET. The clinicopathologic features of 11 renal ES/PNET were studied along with immunohistochemistry for cytokeratin, desmin, CD99, FLI-1, and WT-1. WT were also immunostained for CD99 (5 cases), FLI-1 (10 cases), and WT-1 (9 cases). The patients (6 men, 5 women) ranged from 18 to 49 years of age (mean, 34 yr). The mean tumor size was 11.8 +/- 3.8 cm (mean +/- standard deviation). Presenting symptoms included abdominal/flank pain and/or hematuria. Grossly, all tumors showed necrosis and hemorrhage, and 4 had cystic change. Microscopically, all tumors showed vaguely lobular growth, primitive round cells, and variable rosette formation. Epithelial, myogenous, or cartilaginous differentiation was not seen. Immunohistochemical results on the renal ES/PNET were cytokeratin (2/8 focal), desmin (0/9), CD99 (8/8), FLI-1 (5/8), and WT-1 (0/8). In comparison, the WT only rarely expressed CD99 (1/5) and did not express FLI-1 (0/10), but were usually WT-1-positive (7/9). Follow-up on 8 cases (mean, 28 mo; range, 6-64 mo) showed 4 lung and pleural metastases, 1 bone metastasis, liver metastasis, 2 local recurrences, and 5 deaths from disease (median time to death, 16.8 mo). No case had distant metastatic disease at presentation. Adjuvant therapy included chemotherapy (8 cases), radiation (3 cases), and bone marrow transplantation (1 case). Our study affirms a unique proclivity of renal ES/PNET for young adults and that it is a highly aggressive neoplasm, with rapid death in many cases, usually after the development of treatment-resistant lung metastases. These tumors must be distinguished from blastema-predominant WT and other primitive renal tumors that require different therapy. FLI-1 and WT-1 immunohistochemistry may be valuable in this differential diagnosis, given the known immunophenotypic overlap between ES/PNET and blastema-predominant WT with regard to CD99, cytokeratin, and desmin. The accurate distinction between these two entities has clear prognostic and therapeutic implications.

A 73-year-old man was admitted to the hospital complaining of gross hematuria and left flank pain. Abdominal ultrasonography and computed tomography revealed a left renal tumor with extracapsular extension. Laboratory data showed marked leukocytosis of 121,000/mm3 and hypercalcemia of 12.3 mg/dl without any findings of inflammatory disease or bone metastasis. Enzyme immunoassay of the serum demonstrated a high level of granulocyte colony-stimulating factor (250 pg/ml) and parathyroid hormone-related protein (1,069 pmol/l). Pathological diagnosis of needle biopsy specimen of the primary tumor was transitional cell carcinoma which was suspected to have originated from renal pelvis. Immunohistochemical examination with anti-granulocyte colony-stimulating factor monoclonal antibody demonstrated granulocyte colony-stimulating factor production in cancer cells. The patient underwent a course of systemic chemotherapy, but died two months after diagnosis. To our knowledge, this is the first report of renal pelvic cancer representing granulocyte colony-stimulating factor production and hypercalcemia simultaneously.
