1/886. brain metastasis from prostatic carcinoma.

    Between 1959 and 1971 there were 91 patients with clinically diagnosed prostatic carcinoma who were autopsied at Roswell Park Memorial Institute. In four of these 91 (4.4%) intracerebral metastasis were found at autopsy, but only in one of these four was the diagnosis arrived at pre-mortem. This report describes the diagnosis and management of intracerebral metastasis from prostate carcinoma. It appears, on the basis of our initial experience, that the clinical diagnosis of this entity deserves more frequent consideration.

4/886. Isolation and characterization of a new human breast cancer cell line, KPL-4, expressing the Erb B family receptors and interleukin-6.

    A new human breast cancer cell line, KPL-4, was recently isolated from the malignant pleural effusion of a breast cancer patient with an inflammatory skin metastasis. This cell line can be cultured under serum-free conditions and is tumorigenic in female athymic nude mice. Flow cytometric analysis revealed the expression of Erb B-1, -2 and -3. Dot blot hybridization showed a 15-fold amplification of the erb B-2. reverse transcription-polymerase chain reaction analysis showed a detectable level of mRNA expression of all the Erb B family receptors. In addition, all the receptors were autophosphorylated under a serum-supplemented condition. Unexpectedly, transplanted KPL-4 tumours induced cachexia of recipient mice. A high concentration of interleukin-6 (IL-6) was detected in both the culture medium and the serum of mice. The weight of tumours significantly correlated with the serum IL-6 level. The antiproliferative effect of a humanized anti-Erb B-2 monoclonal antibody, rhuMAbHER2, was investigated. This antibody significantly inhibited the growth of KPL-4 cells in vitro but modestly in vivo. Loss of mouse body weight was partly reversed by rhuMAbHER2. These findings suggest that KPL-4 cells may be useful in the development of new strategies against breast cancer overexpressing the Erb B family receptors and against IL-6-induced cachexia.

5/886. Progression of a Nelson's adenoma to pituitary carcinoma; a case report and review of the literature.

    A 25-year-old woman developed Nelson's syndrome, 3 years after successful bilateral adrenalectomy for Cushing's disease. Despite pituitary surgery and radiotherapy the tumour showed invasive growth, leading to visual disturbance, paresis of the oculomotor nerve and, 34 years after adrenalectomy, to death by widespread purulent leptomeningitis. autopsy revealed a large adenohypophyseal carcinoma with a metastasis attached to the dura, both tumours showing immunocytochemical staining for ACTH and TSH. We review the literature on metastatic adenohypophyseal carcinoma in Cushing's disease and Nelson's syndrome and discuss the role of proliferation markers as indicators of malignant progression.

6/886. A case of metastasizing pleomorphic adenoma.

    The pleomorphic adenoma is the most common benign salivary neoplasm. A case is presented in which a palatal pleomorphic adenoma seeded a metastasis in the medullary cavity of the anterior maxilla, apparently by hematogenous spread after surgical manipulation.

7/886. bone marrow metastases in disseminated alveolar rhabdomyosarcoma: case report with ultrastructural study and review.

    A case of desseminated alveolar rhabdomyosarcoma in an 18-year-old male with leuco-erythroblastic anaemia is described. Numerous bizarre malignant cells, including frequent multinucleated giant cells, were seen in bone marrow aspirates, and osteolytic lesions appeared late in the clinical course. The primary site of the neoplasm remained undertermined during life and also at necropsy, which revealed minute pulmonary metastases and extensive lymph nodal, pleural and skeletal deposits. The diagnosis was confirmed on necropsy tissue by ultrastructural examination which demonstrated numerous thin (5 nm) and thick (15 nm) intracytoplasmic filaments in tumour cells, sometimes organized in bundles; scattered dense Z-band-like bodies, and rod-shaped structures were also seen. The fine structure of the rhabdomyosarcoma in the present case is compared with previous ultrastructural studies. Elongated, thick intracytoplasmic filaments whose diameter corresponds to that of myosin myofilaments are strong evidence for rhabdomyoblastic differentiation and are considered to be the sine qua non of a positive electron microscopic diagnosis of rhabdomyosarcoma. Orgaized bundles of filaments and Z-band-like dense bodies are usually present, and rod-shaped structures are found infrequently, but none of these are necessary for the ultrastructural diagnosis.

8/886. Well-differentiated adenocarcinoma, gastric foveolar type, of the extrahepatic bile ducts: A previously unrecognized and distinctive morphologic variant of bile duct carcinoma.

    Two examples of a rare but distinctive morphologic variant of extremely well-differentiated adenocarcinoma of the extrahepatic bile ducts are reported. One tumor arose in the common bile duct of a 51-year-old man; the other arose in the common hepatic duct of a 27-year-old man. Both tumors were composed predominantly (>95%) of gastric foveolar-type epithelium. Because of their bland nuclear features, low mitotic index, and focal polypoid and lobular architecture, they were initially confused with adenomas. Foci of less-differentiated adenocarcinoma and perineural invasion present in the deep portions of the tumors facilitated recognition. The neoplastic cells and extracellular mucin were periodic acid-Schiff- and alcian blue-positive. By immunohistochemistry, the tumor cells expressed cytokeratins 8 and 20 as well as cathepsin d, as reported in normal foveolar cells. Likewise, p53 overexpression was documented immunohistochemically in both adenocarcinomas, which also stained with the Ki-67 antibody. Despite the well-differentiated nature of the neoplasms and their deceptively benign microscopic appearance, one patient developed recurrence and liver metastasis 5 years after surgery. The other patient is disease-free 2 years following a segmental resection of the common hepatic duct, cystic duct, and gallbladder. The cell phenotype of these tumors can be explained by the ability of the bile duct epithelium to differentiate along gastric cell lines.

9/886. Molecular assessment of clonality leads to the identification of a new germ line TP53 mutation associated with malignant cystosarcoma phyllodes and soft tissue sarcoma.

    Cystosarcoma phyllodes (CSP) is a rare breast neoplasm composed of stromal and epithelial elements. It usually runs a benign course but it may metastasize. In a 31-year-old patient with recurring CSP, a mesenchymal tumor in the leg developed. The question arose whether the latter tumor could be a metastasis from the CSP, which would have major treatment consequences. The problem was addressed using molecular methods, i.e., comparison of the pattern of polymorphic repeat markers on chromosome 17p as well as single strand conformation polymorphism analysis and sequencing of exons 5 to 8 of the TP53 gene in both tumor and normal tissue. An identical pattern of loss of heterozygosity in both breast tumors was demonstrated, but a different pattern was shown in the tumor in the leg. This led to the conclusion that the latter tumor had to be a new primary tumor. A mutation in codon 162 of the TP53 gene was found in the tumor tissue as well as in the normal tissue of this patient. This germ line mutation leads to the replacement of isoleucine by asparagine and most likely has functional consequences. In all four examined tumors of this patient, the normal TP53 allele was lost. This is strong evidence that this germ line TP53 mutation causes the genesis of these two rare primary mesenchymal tumors in this young patient. The current study exemplifies the power of molecular diagnostic methods in investigating the specific clinical problem of clonal relation between two separate tumors. The germ line mutation found in codon 162 of the TP53 gene and the association with cystosarcoma phyllodes have not been described previously.

10/886. Immunohistochemical evaluation of the probability of skin metastasis in gastric cancer.

    We report the case of a 56-year-old man with advanced gastric cancer that manifested as multiple subcutaneous nodules. histology showed irregularly shaped cells with large nuclei and it also showed frequent mitotic figures clustered throughout the dermis. To predict whether metastasis was likely to occur, we performed a controlled study using gastric cancer cells from patients with or without metastases. Tumor cells that had metastasized showed more positive staining for Ki67, PCNA and p53 than those that had not metastasized, although there were no marked differences between the reactivities of these 2 groups for factor viii related antigen, CEA, EGF, or p21 staining. We conclude that immunohistochemical staining for Ki67, PCNA or p53 might be very useful in predicting the possible risk of metastasis of cancer cells.
