A case of
hypernephroma
is presented in which the initial finding was heavy bleeding from a vaginal tumor. Fewer than 90 cases of genital
metastases
in males or females have previously been reported.

Attempt were made to initiate cell lines from 11 specimens obtained from nine patients with
renal cell carcinoma
. Primary cultures were obtained in seven instances with only five long term cells lines. Two of these cell lines were obtained from metastatic tumors in two patients. Using microcytotoxicity assay, both autochthonous and allogeneic lymphocytotoxicity, specific to renal cell tumor, was demonstrated. This would suggest a common cross-reacting tumor-associated antigen. No lymphocytotoxicity could be demonstrated using autochthonous lymphocytes aganist two metastatic tumor target cell lines. This would suggest some antigenic differences between primary tumor and its
metastases
. In seven instances significant complement-dependent cytotoxicity was demonstrated using six different
renal cell carcinoma
target cell lines. Serums from three patients with
renal cell carcinoma
, one without any recurrent tumor and two with
metastases
, appear to significantly block the autochthonous and allogeneic lymphocyte cytotoxicity.

One primary goal of preoperative radiotherapy for
hypernephroma
is to reduce the volume of tumor and, therefore, improve the possibility of resection. It is important that this goal be accomplished promptly so that 4 to 6 weeks after radiation therapy nephrectomy can be attempted. A longer waiting period may allow fibrosis of the normal surrounding tissues and make surgery more difficult. In addition, longer waiting periods could theoretically increase the probability of metastasis. Therefore, we plan to continue clinical investigation on the use of combined intra-arterial actinomycin D and radiotherapy as a possible useful means of improving the possibility of prompt surgical resection, since theoretically this regimen may be a method of increasing the effective radiation dose to the
hypernephroma
without increasing the effective radiation dose to surrounding normal tissue, such as bowel. The method may also have merit as an improved means of palliating selected patients with
metastases
who are symptomatic from a bulky primary
hypernephroma
.

There were 22 patients with vertebral
metastases
and impending neurologic damage from prostatic, vesical and
renal cell carcinoma
treated by decompressive laminectomy combined with local radiotherapy and chemotherapy. The neurological recovery was complete in the prostatic carcinoma patients (10 of 10), partial in the vesical carcinoma patients (2 of 5) and unsatisfactory in the
renal cell carcinoma
patients (1 of 7).

The results of therapy for 78 patients with disseminated
renal cell carcinoma
are evaluated. Symptoms related to the primary tumor were noted in only 28 per cent of the patients and were not difficult to manage in those patients not undergoing nephrectomy. Adjuctive nephrectomy, therefore, is a more appropriate term than palliative nephrectomy when referring to removal of the primary tumor as part of an aggresive combined therapeutic approach. Of patients receiving an adjunctive nephrectomy those with osseous
metastases
only had a better 1-year survival rate (36 per cent) than those with
metastases
to other sites (18 per cent). Complete regression of
metastases
was noted in 12 per cent of patients treated with medroxyprogesterone acetate and adjunctive nephrectomy. The role of adjunctive nephrectomy combined with embolic infarction, hormonal therapy, chemotherapy and/or immunotherapy is discussed.

Ten patients with inoperable
renal carcinoma
underwent embolization of the renal artery. As embolic material homogenized autologous muscle was used. Besides conventional catheters introduced by the Seldinger technique also flow-directed balloon catheters were employed. The merely palliative purposes of embolization were staunching of otherwise untreatable hematuria in eight and reduction of tumor bulk in two cases. Bleeding could be stopped in all, tumor mass reduced in 6 patients as shown by control angiographies. There was always a recanalization of the renal arteries, the vascular tree, however, being much rarefied. Five patients died of the
metastatic cancer
within the first seven months after embolization, one patient three days after embolization due to phlegmonous retroperitoneal infection. Further complications consisted in flank pain, reversible rises of body temperature, blood pressure and serum creatinine levels. Thrombotic occlusion of deep veins occurred in two patients. The only true benefit of embolization for the patient consists in a relatively simple, fast and safe way to control an otherwise untreatable hemorrhage from inoperable
renal carcinoma
. Whether prolongation of survival can be reached remains doubtful in spite of a reduction of the tumor mass.

Survival factors of 86 patients with metastatic renal cell carcinoma were studied by computer analysis. Cumulative survival was 53 per cent at 6 months, 43 per cent at 1 year, 26 per cent at 2 years and 13 per cent at 5 years. Survival was influenced favorably by confinement of
metastases
to the lungs, by the absence of local recurrence or persistence of tumor and by a longer interval free of disease after removal of the primary tumor. Medical therapy improved survival during the first year after diagnosis of
metastases
but no objective regression of tumor was observed. Excision of metastatic foci significantly improved survival for up to 5 years (p less than 0.05 and p less than 0.02) after which most patients died of recurrence. Palliative or adjunctive nephrectomy in patients with
metastases
was associated with a 6 per cent mortality rate but it increases survival over other patients with
metastases
at the time of diagnosis of
renal carcinoma
who did not undergo nephrectomy. This difference was owing to patient selection and survival of those who had adjunctive nephrectomy was no greater than that of the study population as a whole. However, based on the factors that were associated with improved survival palliative nephrectomy may be beneficial when a limited number of
metastases
treatable by excision or radiation therapy are present, when effective systemic therapy exists or when the primary tumor produces severe symptoms.

Arterial embolization was performed in nine patients with
metastases
from
renal carcinoma
who had severe pain resistant to conventional therapy. Patients with
metastases
in the ilium (four), the lumbosacral spine (one), and the base of the skull (one) experienced pain relief lasting from one to six months. The other three patients, who had
metastases
in the proximal femur, underwent preoperative embolization to facilitate tumor curettage and internal hip fixation. No significant complications were seen with this therapeutic approach.

The natural history, presenting signs and symptoms, and radiologic evaluation of patients with
hypernephroma
are reviewed. Radical nephrectomy is the treatment of choice in patients free of
metastatic disease
. Patients who have evidence of
metastatic disease
should not be subjected to nephrectomy unless hemorrhage, pain, or some other severe local problem warrants it. Radiotherapy and chemotherapy may be useful as adjunctive therapy in a patient with
metastatic disease
.

Thirteen patients with
renal carcinoma
were examined for tumour-directed, cell-mediated hypersensitivity (TCMH) by means of the leucocyte migration technique, and for general immunocompetence (GIC) by means of quantitation of T- and B-cells in peripheral blood and studies of lymphocyte transformation in vitro using a panel of antigens and mitogens. Eight out of 13 patients had evidence of TCMH, six out of 13 had abnormal GIC. Any correlation between the presence of TCMH and normal/abnormal GIC was not found. There was a trend towards a positive correlation between the absence of distant
metastases
and evidence of TCMH. If both TCMH and GIC were considered, significant correlation between the presence of distant
metastases
, lack of TCMH and/or abnormal GIC was demonstrated. It is concluded that the defect TCMH usually found in patients with
renal carcinoma
and disseminated disease cannot be explained exclusively by defects in GIC.
