Clear cell sarcoma of kidney (CCSK) is a rare but distinct tumor of childhood frequently confused with
Wilms' tumor
(
nephroblastoma
). It has a characteristic histology, a marked predilection for metastasis to bone, and an aggressive clinical course with a high relapse rate in spite of surgical excision, chemotherapy and radiotherapy. We report the first histologically proven CCSK in a Malaysian patient. This was an 8-mth-old Malay boy who was clinically diagnosed to have stage I Wilms' tumor. Despite treatment, he developed multiple
metastases
10 mths after initial presentation and died soon after. Emphasis is placed on recognizing this entity in view of (1) its naturally aggressive behaviour and (2) the prospect of improving prognosis with currently recommended intensified chemotherapeutic regimes. Its immunohistochemical profile of vimentin-positivity and negativity for epithelial membrane antigen, cytokeratin and Factor-8 related antigen is more in favour of a mesenchymal or glomerular origin than a tubular or vascular origin.

Methods were developed to test angiogenic response to human tumor implants and various biologic agents in the cornea of rabbits and non-human primates (Macaca arctoides). Crude PDGF preparations were found to have significant angiogenic effect. Purified, recombinant PDGF preparations were also effective inhibitors (e.g. pentoxifylline (Px) (which also were found to release PgI2 and t-PA) inhibited human tumor implant induced angiogenesis and reduced spontaneous

in 3 transplantable murine tumors (Furth-Columbia
Wilms' tumor
in Furth-Wistar rats, C-1300 neuroblastoma in A/J mice and HM-Kim mammary carcinoma in Wistar rats) but not in the NIH adenocarcinoma in Balb/c mice. Sodium diethyldithiocarbamate (DDTC), a metal complexing agent with special affinity to copper and anti-thyroid as well as, immune stimulating activity was shown to be anti-angiogenic and to potentiate the effect of Px. The anti-fibrinolytic agents epsilon amino caproic acid (EACA) and tranaxamic acid (t-AMCHA) were anti-angiogenic. DDTC and Px were synergistic from this point of view.

Previous studies using somatic cell hybridization of highly metastatic and nonmetastatic rat prostatic cancer cells demonstrated that the resultant hybrids were nonmetastatic if all of the parental chromosomes were retained. Somatic hybrid segregants which underwent nonrandom chromosomal losses reexpressed high metastatic ability. These results demonstrated that there are gene(s) the expression of which can suppress metastatic ability of prostatic cancer cells. To identify the location of homologous gene(s) in the human, specific human chromosomes were introduced into highly metastatic rat prostatic cancer cells using the microcell-mediated chromosome transfer. Introduction of human chromosome 11 into highly metastatic rat prostate cancer cells results in suppression of metastatic ability without suppression of the in vivo growth rate or tumorigenicity of the hybrid cells. Spontaneous deletion of portions of human chromosome 11 in some of the clones delineated the minimal portion of human chromosome 11 capable of suppressing prostatic cancer

There are several urologic disorders which also involve the eye and orbit. We have compiled examples of these and reviewed the literature.
Metastasis
from genitourinary malignancy (including neuroblastoma),
Wilms tumor
, Reiter syndrome, tuberous sclerosis, von Hippel-Lindau disease, and oxalosis may all have ophthalmologic manifestations. Urologists need to be aware of these and obtain appropriate consultation in order to fully care for patients with these diseases.

In a nationwide study (1980-1988) for the diagnosis and treatment of
Wilms
' tumours (nephroblastomas), which are highly malignant embryonal mixed tumours of the kidney and show distant
metastases
at the time of diagnosis in 10-20% of cases, 78% of 373 children had a standard type
Wilms' tumour
, 7% had benign variants and 14% had high grade malignancy variants of the classical type. 20 of the 25 benign variants occurred in infants. From the 25, 16 tumours were congenital mesoblastic nephromas, 14 of which occurred in infants. As the detection of a solid renal tumour mass in the prenatal sonogram (showing an echotexture resembling that of the liver) may suggest
Wilms' tumour
, we analysed 11 neonates (1-14 days old), in which
Wilms
' tumours had been diagnosed (n = 11; 2.9%) for the histological subtype. In 9 of the 10 neonates, the final diagnosis was congenital mesoblastic
nephroma
. These congenital mesoblastic nephromas are cured by surgery alone. Thus, if a solid renal tumour suspected as a
Wilms' tumour
, is prenatally detected, the most probable diagnosis is that of the benign variant congenital mesoblastic
nephroma
, and, in this case, preterm delivery (e.g. to prevent metastasising and to start treatment as early as possible) is not indicated.

A case is reported of
Wilms' tumor
associated with multiple pulmonary
metastases
histologically showing maturation of the tumor cells at 9 years after the resection of the primary tumor and intensive therapy. A huge tumor of a 22-month-old patient's right kidney was resected. The tumor was diagnosed as
Wilms' tumor
of mesenchymal type (stage 1), which consisted of predominantly immature mesenchymal tissue including rhabdomyoblasts, smooth muscle and fibrous tissue, and few blastemal and epithelial components. Intensive preoperative and postoperative chemotherapy with actinomycin D and vincristine and postoperative irradiation therapy totaling 16 Gy were carried out. The patient was regularly followed up uneventfully until 9 years after the surgery. On routine chest x ray at the age of 10 years 11 months, multiple pulmonary nodules were found. The excised nodules from the bilateral lungs disclosed similar histology, exclusively composed of dense collagen bundles and fibrocytes intermingled with mature striated muscle bundles. No immature tumor components were detected. The possible effect of intensive therapy in this maturation was stressed, although spontaneous benign differentiation of tumor cells cannot be excluded.

To evaluate the prognosis of patients with
Wilms' tumor
who have pulmonary densities identified on a computed tomographic (CT) scan of the chest, but have a negative plain chest radiograph, we reviewed the treatments and outcome of 32 patients randomized or followed on National
Wilms' Tumor
Study (NWTS)-3. The 4-year event-free and overall survival percentages of 18 of these patients who had a favorable histology tumor and were treated as stage IV tumors with three or four drugs plus whole-lung irradiation were 88.1% and 94.0%, respectively. The 4-year event-free and overall survival percentages for nine favorable histology patients treated less aggressively based on the extent of locoregional disease with two or three drugs and without whole-lung irradiation were 88.9% and 88.0%, respectively. There were no statistically significant differences in the 4-year event-free or overall survival percentages between the two groups. The current data do not demonstrate improved survival for favorable histology patients treated with whole-lung irradiation for pulmonary
metastases
identified only on chest CT scan. However, due to the small number of patients included, no statistically valid conclusions regarding the roles of Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH) and/or whole-lung irradiation in the treatment of these patients can be drawn from the present analysis. Additional patients need to be systematically studied to determine if these preliminary observations can be confirmed.

We have evaluated the clinicopathologic characteristics, survival probabilities, patterns of treatment failure, and late toxicities in a group of 51
Wilms' tumor
patients with pulmonary
metastases
evaluated at our center between 1968 and 1988 and treated intensively with surgery, multiagent chemotherapy, and radiotherapy. Twenty-one patients had pulmonary
metastases
at diagnosis (Stage IV-p) and 30 had pulmonary relapse after initial treatment for nonmetastatic disease. With a median follow-up time of 83 months, actuarial 5- and 10-year survival probability for the group as a whole is 59%. For the subset of patients with favorable histology Stage IV-p disease, 10-year survival probability is 77%, whereas for the subset with relapsed anaplastic or sarcomatous disease, 10-year survival probability is 22%. The lung was the predominant site of failure even in patients who had received relatively high doses of pulmonary radiotherapy. Late effects seen in patients with over 10 years of follow-up included musculoskeletal and soft tissue growth abnormalities (93% incidence) as well as breast hypoplasia and endocrinologic abnormalities. Second malignant neoplasms of the breast, thyroid, and pancreas were observed at post-treatment intervals of 17, 3.5 and 12 years, respectively.

To determine the effect of surgical excision of pulmonary
metastases
from
Wilms' tumor
on postrelapse survival, we retrospectively analyzed the clinical courses of 211 patients with stages I to III, favorable or unfavorable histology
Wilms' tumor
entered on National
Wilms' Tumor
Study-1, -2, or -3 whose first recurrence was limited to the lungs. There was no difference in the 4-year postrelapse survival percentage of favorable-histology patients with a solitary pulmonary metastasis who did or did not undergo surgical removal of the metastasis in addition to pulmonary irradiation and chemotherapy. Although histological confirmation of pulmonary relapse is frequently indicated, the present data suggest that therapeutic removal of pulmonary
metastases
from patients with relapsed
Wilms' tumor
does not increase the percentage of patients who survive for 4 years postrelapse, compared with treatment with whole-lung irradiation and chemotherapy.

Cell adhesion molecules (CAMs) of the immunoglobulin supergene family may play important roles in tumorigenesis and the development of
metastatic disease
. In a variety of human malignancies, tumor progression has been observed to be associated with changes in CAM expression. An early event in colorectal tumorigenesis appears to be the down regulation of a normally expressed CAM, DCC. Over-expression of a second CAM, carcinoembryonic antigen, is associated with colorectal tumors which have a high risk for metastasis development. Several tumors, including
Wilms
tumors and neuroblastoma, have been found to express a developmentally regulated form of NCAM which inhibits a variety of cell-cell interactions. Malignant cells not only show aberrations in the expression of their CAMS and thus their normal cell-cell interactions, but establish new adhesive interactions. The development of metastatic potential in cutaneous melanoma is associated with the de novo expression of two CAMs, one of which is ICAM-1, a molecule mediating adhesion between the tumor cells and leukocytes.
