The time to detection of metastatic bone disease (MBD) by radiographic examination was studied in 221 patients with advanced breast cancer. None of the patients had bone metastases by radiography or bone marrow carcinosis, evaluated by bilateral iliac crest biopsy. The period of follow-up after first recurrence was 46 months. Fifty-five patients (25%) had MBD; 89 patients died without MBD. The cumulated rate of MBD was 14% and 27% after 1 and 2 years, respectively. The actuarial time to MBD was associated significantly with the presence of positive regional lymph nodes at primary diagnosis, the occurrence of metastases in the mediastinum, and the presence of visceral metastases. Moreover, a positive bone scintigraphic scan at the time of first recurrence and abnormal biochemical analyses from serum also were associated significantly with a shortened time to MBD. Micrometastases in the bone marrow, as detected by monoclonal antibodies against epithelial markers (epithelial membrane antigen and cytokeratin), were present in 18% of the patients. The presence of such tumor cells was not associated with development of radiologic MBD. Cox analyses revealed that the result of bone scintigraphic scanning and the presence of visceral metastases were the most important and independent predictors of the time of MBD. Four distinct prognostic groups were identified based on the status of these two variables. The recognition of these prognostic groups has several implications for clinical and therapeutic management of patients with recurrent breast cancer.

We differentiate (continuing the scheme of the National Wilms' Tumor Study) three groups of Wilms' tumors (WT), which for practical reasons also encompass WT variants: 1. a group of low-grade malignant tumors comprising 9.3% of cases (congenital mesoblasticnephroma; cystic, partially differentiated nephroblastoma); 2. the main group of tumors with histologically standard malignancy and constituting 77.7% of cases, against which a combined therapy is used depending upon age and stage of spread; and 3. a small group of tumors of high-grade malignancy (anaplastic WT, clear cell sarcoma of the kidney; malignant rhabdoid tumor of the kidney). This latter group constitutes only 13% of cases but is responsible for a high percentage of total deaths due to WT. To the tumor group with standard malignancy belong the classic triphasic WT (without anaplasia) as well as WT "with quantitative deviations", in which either the blastemic, the epithelial, or the stroma component dominates. In the differential diagnosis the relatively frequent blastemic WT must be differentiated from other so-called small, round, and blue cell tumors of childhood, especially the undifferentiated neuroblastomas. Pseudo-rosettes and cytokeratin expression are signs of an "early" epithelial differentiation. Anaplastic WT (comprising 6.1% of our cases) are diagnosed according to the criteria of BECKWITH and PALMER (1978). They are aneuploid tumors and occur predominantly in children over two years of age. By contrast, the histogenetic still undefined clear cell sarcomas and malignant rhabdoid tumors of the kidney occur chiefly in children under two. Both tumors are diploid, notwithstanding their high-grade malignancy. Clear cell sarcoma, which contains a high content of vessels and comprises 3.7% of our cases, consists of cells with weakly stained and partially vacuolized cytoplasm. In contrast to normal WT, clear cell sarcoma often progresses to bone metastases. Malignant rhabdoid tumor (2.7% of our cases) possesses cells with large, roundish nuclei, pale chromatin, very prominent nucleoli and characteristic spherical intermediate filament condensations. Cross striation and myoglobin are never present. Malignant rhabdoid tumor is not a genuine kidney tumor; it may also occur extrarenally. Low-grade congenital mesoblastic nephroma is a spindel cell tumor often exhibiting high cellularity and characterized by fingerlike projections extending into the adjacent kidney tissue. Nephroblastomatosis, with preferential perilobular localization, is a potential WT precursor found in 25% to 40% of all nephrectomy specimens containing WT and in all cases of bilateral and multifocal WT. Nevertheless, only a small proportion of the usually very small "nephrogenic remnants" lead by way of an adenomatous proliferation to manifestation of WT.(ABSTRACT TRUNCATED AT 400 WORDS)

Undecalcified methylmethacrylate(MMA)-embedded biopsies and surgical specimens from 20 bone metastases of differentiated or medullary thyroid carcinomas or prostate carcinomas were investigated immunohistologically for the presence of thyroglobulin, cytokeratin, vimentin, and CEA. The immunoreactions on MMA-sections revealed the same staining patterns as those demonstrated using paraffin sections of the primary lesions. Conversely, immunohistological examination of decalcified paraffin-embedded specimens of the same metastases yielded either false-negative results or results that did not allow an exact evaluation. The findings demonstrate the usefulness and limitations of immunohistology when performed on undecalcified plastic-embedded material.

Breast carcinoma arose in or in conjunction with microglandular adenosis (MGA) in 14 of 60 (23%) patients with MGA listed in the authors' files. This article describes the clinicopathologic and immunohistochemical features and prognosis of these carcinomas. The median patient age was 47 years (range, 26-68 years). All patients had a mass. Six (43%) had a family history of breast carcinoma. Lymph node metastases were found in 3 of 11 axillary dissections. Ten patients treated by mastectomy were recurrence-free, with a median follow-up of 57 months (range, 3-108 months). Two of three patients treated by excisional surgery were recurrence-free 12 and 105 months later. The third woman had bone metastases at 51 months and was alive 98 months after treatment. Carcinoma arose in the MGA in 13 patients. In these patients, in situ carcinoma was found in expanded MGA glands composed of cells with vesicular poorly differentiated nuclei. One patient with benign MGA had carcinoma develop in the opposite breast that was not associated with MGA. When it arose in MGA, basement membranes were present in benign MGA and in situ carcinoma but tended to be disrupted in invasive foci that appeared to be formed by coalescent MGA glands. Strong immunoreactivity for cytokeratin, S-100, and cathepsin D was detected in carcinomas. Two carcinomas had nuclear progesterone receptors, and one of these had estrogen receptors. One carcinoma had positive findings for HER-2neu, and four had immunoreactivity for p53 protein. The following conclusions were drawn from these observations: (1) carcinomas arising in MGA have a distinctive histopathologic pattern; (2) the carcinomas are composed of epithelial cells (cytokeratin positive, actin negative) that are strongly immunoreactive for S-100 protein and cathepsin D; and (3) with a median follow-up of nearly 5 years, patients with these carcinomas had a relatively favorable prognosis, despite histopathologic and immunohistochemical features usually associated with a poor prognosis.

A breast tumour in a 47-year-old female with axillary lymph node metastasis was interpreted as the rare malignant adenomyoepithelioma based on morphological and immunohistochemical studies. Multiple bone metastases developed and the patient died after 7 months. The malignant neoplasm consisted of cords and interlacing bundles of spindle cells with indistinct cell borders and clear cytoplasm. The cells stained positively for cytokeratin, S-100 protein, GFAP, and muscle-specific actin, and possessed basal lamina, pinocytic vesicles, tonofilaments, desmosomes, and intermediate filaments with dense bodies. In some areas, cells with microvillous projections enclosed small spaces. In the breast, foci of myoepithelioma with various morphological subtypes and infiltration coexisted, demonstrating the origin of the malignant tumour. The histogenesis of the myoepithelial tumours is discussed.

In a prospective study at the University of Erlangen, Dept. Gynaecol, and Obstet., 228 patients with breast cancer during their primary surgery and 20 patients during their metastatic surgery, underwent bone marrow punctions at six punction sides, which were twice at the sternum and twice at both iliac crest. The control group was 20 patients without an invasive carcinoma. Aim of the study was to detect or exclude tumour cells in the bone marrow via examination of the biopsies with monoclonal antibodies EMA and cytokeratin and consequently to find out the meaning of the results as prognostic criteria by statistical measurements. Tumour cells in the bone marrow were detected in 46.5% (106/228) of the patients, who underwent a bone marrow biopsy during primary surgery. 21% (23/106) of the patients who were bone marrow positive, but only 5.75% (7/122) of the patients, who were bone marrow negative, developed metastases during a median follow-up of 20 months. This difference is statistically significant. 17 of the 30 patients with recurrences developed bone metastases; 16 of them were EMA-positive. The median recurrence-free interval was 5 months in the bone marrow positive group and therefore noticeably shorter, than in the bone marrow negative patient group with 11 months. Of the nodal negative patients, 2 bone marrow positive patients developed distant metastases. With the knowledge of the nodal status and bone marrow biopsy result, it was possible to predict 28 of the 30 patients correctly in respect of their risk to metastasize. The result of the bone marrow puncture was proved in a multivariate analysis to be an independent prognostic factor.(ABSTRACT TRUNCATED AT 250 WORDS)

Serum tissue polypeptide-specific antigen (TPS), prostate-specific antigen (PSA), and prostatic acid phosphatase (PAP) concentrations were serially measured in 31 prostate cancer patients with bone metastases who had relapsed following hormonal therapy. Of these subjects 7 had well-differentiated cancer (G1), 13 patients were assessed to have moderately differentiated tumor (G2) while in 11 subjects poorly differentiated tumor (C13) was found. With increasing tumor grade (G1 to G3), a proportional increase in mean TPS value was found while the increase in respective PAP serotest values was not linear. Simultaneously measured mean PSA values showed a curved effect. Both PSA and PAP serotest concentrations depend on the respective hormone-dependent gene expressions that gradually decrease with tumor dedifferentiation. Therefore, in progressive hormonally treated stage D2 prostate cancer patients an androgen-independent TPS serotest seems to be a useful clinical addition for monitoring protocols. The combined use of TPS, PSA, and PAP seems to give a better reflection of tumor status. According to the bone scan data metastatic tumor mass in G3 carcinomas was virtually equal to cancer burden in G2 tumors. Hence, the marked elevation of TPS serotest values in G3 adenocarcinomas could not be attributed to greater tumor mass but was most likely due to an increase in proliferation rate. Some authors have recently proposed cytokeratins 8, 18, and 19 to be the origin of TPS serum findings. However, cytokeratin content has been proven to be lower in G3 tumors than in better-differentiated neoplasms.(ABSTRACT TRUNCATED AT 250 WORDS)

Adamantinoma is a rare primary tumour of long bones containing mesenchymatous and epithelial cells. There has been some controversy over the pathogenesis. We observed a localization in the right tibia. A 22-year-old patient from Algeria was seen for spontaneous progressively increasing pain in the upper part of the right tibia. The patient's general health had deteriorated somewhat, with fever. On examination there was ulceration of the skin, costal and pelvic pain and inflammatory right inguinal lymph nodes. Radiography revealed lateral metaphyseal lytic image with interruption of the cortex also seen on magnetic resonance imaging which revealed invasion of the soft tissue and multiple bilateral pulmonary nodules. Bone scintigraphy showed several zones of hyperfixation. The diagnosis of adamantinoma was confirmed by pathology examination of the biopsy specimen. On surgical exeresis, the capsule of the knee joint was found to be involved without invasion of the knee joint. Node dissection showed inguinal and popliteal invasion. Macroscopically, the surgical specimen was a red-whitish osteolytic tumour. Microscopically, the tumour was composed of hyperchromatic epithelial cells in an abondant fibrous stroma. Immunohistochemical studies were negative for vimentine, cytokeratin and factor VIII. Adjuvant chemotherapy was based on a sarcoma protocol. Unfortunately, after two cycles, white cell counts fell sharply and multiple skin nodules appeared together with progression of the bone metastases. The chemotherapy was modified without any therapeutic effect and the patient died in February 1993. An epithelial origin would appear most probable, but at least two groups of adamantinoma can be described: one with typical epithelial differenciation and one overlapping to the differential diagnosis of osteofibrous dysplasia. Although considered as a low grade malignant tumour, we emphasize the aggressive forms with local relapse or metastatic resistance to chemotherapy. Treatment relies on wide surgery and prognosis is generally good. Neither chemotherapy nor radiotherapy has stood the test of time in cases with metastasis.

A primary leiomyosarcoma of the thyroid gland in a 72 year old Japanese woman is described. This is the second case reported in the English literature. The patient presented with a 7 month history of a gradually expanding tumor in the right neck. The surgical specimen taken by thyroid lobectomy revealed a relatively well demarcated tumor, 2 x 2 x 3 cm in size, confined to the right lobe. Histologically, the tumor showed a classical leiomyosarcomatous appearance of interlacing fascicles of spindle-shaped cells with occasional blunt-ended nuclei and a high frequency of mitotic figures. Immunohistochemistry of the tumor cells clearly showed smooth muscle differentiation; the cells were positive for desmin, muscle-specific actin and vimentin and negative for cytokeratin, epithelial membrane antigen, carcinoembryonic antigen, thyroglobulin and calcitonin. The patient was free of disease for 3 years and 11 months without further treatment when evidence of multiple bone metastases appeared on bone scintigraphy. She died of pneumonia 4 years and 3 months after the lobectomy.

The aim of this study was to describe a child with a right cerebellar hemisphere metastasis from primary clear cell sarcoma of the kidney without evidence of bone metastases, and to investigate the immunohistochemical features of primary and metastatic tumors. A 12-month old boy was admitted our hospital due to an abdominal mass. Abdominal computed tomography revealed a large right renal tumor. Tumor was removed with nephrectomy. Histopathologic examination of tumor revealed clear cell sarcoma of the kidney. The patient received radiotherapy and chemotherapy in postoperative period. He suffered from gait disturbance and confusion 8 months later. A computed tomography scan revealed a tumor that was enhanced with contrast medium at right cerebellar hemisphere concomitant with ventricular enlargement. After ventriculo-peritoneal shunting procedure, tumor was excised totally and histopathologic diagnosis showed metastasis of clear cell sarcoma of the kidney. Immunohistochemically vimentin, actin, desmin, neuron specific enolase, cytokeratin, P 53, Ki-67 and P-170 were performed using formalin fixed, paraffin embedded sections. Both of the tumors were positive for vimentin and negative for desmin, actin, neuron specific enolase, cytokeratin and P 53. Scattered nuclei were stained by Ki-67 in primary and metastatic cerebellar tumor. Both primary and metastatic tumors were negative for p53 and P-170. The treatment consisted of surgery, radiotherapy and chemotherapy. The patient is alive and well without evidence of recurrence 16 months after second surgery. Clear cell sarcoma of the kidney is most commonly associated with bone metastasis. Cerebellar metastasis of clear cell sarcoma of the kidney is very unusual. To the best of our knowledge, this patient is second case in the English literature. With review of the literature, our immunohistochemical findings support the theory that relapse and metastasis of primary clear cell sarcoma of the kidney are not related with increase of aggressiveness.
