acid-phosphatase and Carcinoma--Transitional-Cell

We report two transitional cell carcinomas of the urinary bladder containing numerous osteoclast-type giant cells that stained for vimentin and acid phosphatase (with and without tartrate) and were negative for cytokeratin and lysozyme. One tumour, in a 65-year-old man, was composed of papillary transitional cell carcinoma, invasive poorly differentiated carcinoma with a prominent spindle cell component and numerous osteoclast-type giant cells; repeat curettage 2 months later showed no residual tumour. The second tumour occurred in a 75-year-old woman who underwent a radical cystectomy for a deeply invasive transitional cell carcinoma with a spindle and anaplastic giant cell component and areas containing numerous osteoclast-type giant cells. Osteoclast-type giant cells, which appear to be reactive, should be distinguished from the neoplastic giant cells of giant cell carcinoma.

The differential diagnosis of mucin-producing adenocarcinoma of the prostate includes conventional prostatic adenocarcinoma with mucin production, secondary adenocarcinoma usually of colorectal origin and, very rarely, urothelial-type adenocarcinoma arising from either the prostatic urethra or proximal ducts. Conventional prostatic adenocarcinoma with mucin production is readily identified by routine microscopy and immunohistochemistry. The distinction between secondary adenocarcinoma and urothelial-type adenocarcinoma, however, can present a significant diagnostic challenge. In addition, documented examples of the latter in the prostate are exceptionally rare. A transurethral resection of prostate specimen and prostatic needle biopsies from two patients showing urothelial-type adenocarcinoma of the prostate were identified in our consultation files. One of the patients subsequently underwent a radical prostatectomy. Both patients had negative gastrointestinal endoscopic workups. Transurethral resection of prostate material from two patients with clinically confirmed secondary adenocarcinoma of colonic origin involving the prostate and a prostatectomy specimen with mucinous conventional prostatic adenocarcinoma were also identified for comparison purposes. Formalin-fixed, paraffin-embedded sections were stained for prostate-specific antigen (PSA), prostatic acid phosphatase, carcinoembryonic antigen, cytokeratin 7, cytokeratin 20 and high molecular weight cytokeratin 34betaE12. The urothelial-type adenocarcinoma cases were diffusely positive for cytokeratin 7 and focally positive for 34betaE12 and cytokeratin 20, consistent with an origin from the urothelium of the prostatic urethra or proximal prostatic ducts. In contrast, the secondary adenocarcinoma of colonic origin cases were diffusely cytokeratin 20 positive and either negative or focally positive for cytokeratin 7 and negative for 34betaE12. The mucinous conventional prostatic adenocarcinoma was positive for PSA and prostatic acid phosphatase and negative for cytokeratin 7, cytokeratin 20 and 34betaE12. All tumors were positive for carcinoembryonic antigen.

Transitional cell carcinoma (TCC) of the urinary tract is a chemosensitive tumor. Most deaths from TCC of the urinary tract are caused by metastasis, which is resistant to conventional chemotherapy. Frequent sites of metastases from TCC of the urinary tract are regional lymph nodes, liver, lung, and bone. Of these distant metastases, bone metastasis is consistently resistant to cisplatin-based conventional chemotherapy. Therefore, in this study, we investigated whether or not a newly developed minodronate, YM529, could prevent osteolytic bone metastasis of human TCC and also enhance the effect of docetaxel in a bone tumor model of athymic nude mice.. In the present study, we evaluated the effect of in vitro treatment with minodronate and/or docetaxel on the proliferation by cell count, the induction of apoptosis by terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) assay, and the biological activity of osteoclast by pit formation assay in human bladder cancer cell line, UMUC-14, and mouse osteoclast cells. In vivo, we examined the effect of minodronate in a bone tumor model of athymic nude mice, in which the percutaneous intraosseal injection in the tibia of UMUC-14, leads to osteolytic bone tumor, as a bone metastasis model. To examine whether or not minodronate could inhibit tumorigenicity and enhance the effect of the chemotherapeutic agent, docetaxel, we gave minodronate i.p. and/or docetaxel i.p. to nude mice 3 days after an intraosseal tumor implantation. Moreover, proliferation and the induction of apoptosis of cancer cells and osteoclasts in bone tumors were determined by immunohistochemistry and the TUNEL assay.. In vitro: In vitro treatment with docetaxel inhibited proliferation and resorption pit-forming activity and induced apoptosis of mouse osteoclast cells and UMUC-14 cells. In vitro treatment with minodronate inhibited proliferation and activity and induced apoptosis of mouse osteoclast cells but not UMUC-14 cells. The treatment with minodronate enhanced the inhibition of proliferation and activity by docetaxel in osteoclasts. In vivo: In vivo combination therapy with docetaxel and minodronate significantly reduced the tumor incidence compared with the control (P < 0.05) and also growth of intraossal TCC in athymic nude mice compared with the control (P < 0.001), single therapy with docetaxel (P < 0.01), and minodronate (P < 0.05). Drug-induced body weight loss was not significantly different in any treatment group. Therapy with minodronate significantly enhanced inhibition of proliferation by docetaxel in osteoclasts of bone tumors compared with the control (P < 0.01), single therapy with docetaxel (P < 0.01), and minodronate (P < 0.05).. These studies indicate that combination therapy with minodronate and docetaxel may be beneficial in patients with bone metastasis of human TCC in the urinary tract.

To find out Gleason grades, scores and to see the correlation of these morphological features with tumour markers in prostatic carcinoma.. A descriptive study.. The study was conducted at the Departments of Histopathology and Chemical Pathology, Armed Forces Institute of Pathology, Rawalpindi, over a period of one year.. Fifty cases of prostatic carcinoma were studied. Gleason grades and score of tumour were determined by doing haematoxylin and eosin (HE) staining. Pre-operative serum prostatic acid phosphatase (PAP) and prostate-specific antigen (PSA) assays were carried out in these cases.. The patients seen were between 50-102 years of age with an average of 70.9 years. There were 49 cases of adenocarcinoma and 01 case of mixed adeno and transitional cell carcinoma of prostate. Twenty-eight (56%) patients had Gleason score of 5-7. Twenty-nine (58%) patients were having serum PSA levels between 10.0 ng/ml and 50.0 ng/ml. Thirteen (26%) cases showed PSA assays >50 ng/ml. The sensitivity of PSA test was 84 % in these cases. Thirty-five (70%) patients were having PAP values >3.7 U/l (sensitivity 70 %).. The Gleason grading system is a specific morphological predictor. The serum PSA showed better sensitivity and specificity with Gleason grades and scores as compared to serum PAP. The serum PAP levels showed better correlation with morphological features as compared to serum PSA.

Prostatic adenocarcinoma and urothelial carcinoma (transitional cell carcinoma) may coexist in the prostate. However, a carcinoma with mixed features has not been recognized. Four cases, three surgical pathology cases and one autopsy case of prostatic adenocarcinoma with urothelial carcinoma features, were retrospectively found in a urological pathology teaching file maintained from 1984 to 1993. Subsequently, 181 consecutive cases of radical prostatectomy from 1994 to 1999 were reviewed, and two prostatic adenocarcinoma areas with features of urothelial carcinoma were identified. Areas with urothelial carcinoma features were identified in the intraductal component of the carcinoma in five cases and in the invasive component in three cases. The intraductal carcinoma with urothelial carcinoma areas usually merged with regions of prostatic adenocarcinoma with a papillary or cribriform pattern. All prostatic adenocarcinomas having areas with urothelial carcinoma features were of high stage, and five of six cases had ductal features. The urothelial carcinoma component displayed a positive reactivity for thrombomodulin and negative or weaker reactivity for PAP and PSA than the prostatic adenocarcinoma component in the same tumor. Excluding the case noted at autopsy, all patients died of the disease within 3 years. Urothelial carcinoma features were usually associated with ductal carcinoma of high stage. Areas of prostatic adenocarcinoma with urothelial carcinoma features should be considered histopathologically as areas of mixed carcinoma of the prostate. Prostatic adenocarcinoma with areas of urothelial carcinoma features may pose a difficult differential diagnosis problem with urothelial carcinoma, especially with small biopsies with focal weak immunoreactivity for PAP, PSA, and thrombomodulin.

In vitro and experimental studies of mesenchymal-epithelial interaction for the prostatic stroma have demonstrated that the prostatic stroma is capable of inducing the nonprostatic epithelium to acquire many features of prostatic epithelium. We investigated whether this phenomenon could be observed in vivo in human prostatic stroma. MATERIALS AND METHODS Sixty transitional cell carcinoma (TCC) of the urinary bladder: (a) 20 with glandular lumen; (b) 20 without glandular lumen: (c) 10 mixed TCC-adenocarcinoma (ACA); and (d) 10 with synchronous or metachronous TCC of the prostate; and three primary TCC of the prostate were examined and submitted for immunostaining for prostatic acid phosphatase (PAP) and prostatic specific antigen (PSA).. There was a spectrum of immunostaining for PSA ranging from negative reactivity in TCC without glandular lumen of the urinary bladder, to focal and weak reactivity in single cells with varying degrees of nonmucinous glandular differentiation and to strong reactivity in groups of cells in primary and synchronous or metachronous TCC in the prostate. The areas of carcinoma geographically closest to the prostate and with the most extensive nonmucinous glandular differentiation displayed the most frequent and strongest immunoreactivity for PSA. The immunoreactivity for PAP was usually stronger than for PSA. Four cases of TCC and mixed TCC-ACA were immunoreactive only for PAP. Furthermore, there was a change in the phenotype of TCC in the urinary bladder as it spread into the prostate. For 10 TCC in the urinary bladder with synchronous or metachronous tumor in the prostate, all TCC in the urinary bladder were negative for PAP and PSA, whereas six TCC in the prostate were focally positive.. The spectrum of immunoreactivity for PAP and PSA and the change in immunoreactivity of TCC of the urinary bladder as it spreads into the prostate are likely induced by the prostatic stroma through the mechanism of mesenchymal-epithelial interaction.

We report herein a case of a collision tumor composed of high-grade urothelial carcinoma and a Gleason grade 3+4 prostate adenocarcinoma metastasizing to the same lymph node. After the patient underwent cystoprostatectomy for known urothelial carcinoma, he was incidentally discovered to have a second primary prostate tumor. Lymph node examination revealed that one node appeared to have metastatic foci from both primary tumors. The presence of 2 tumor types colliding in the same lymph node was confirmed using immunohistochemical stains, including monoclonal carcinoembryonic antigen, prostate-specific antigen, prostatic acid phosphatase, cytokeratins 7 and 20, and CD57. We also stained both primary tumors with the same panel as an internal control. Although 2 similar collision tumors have been reported in the literature in the past, neither used a battery of immunohistochemical stains to definitively distinguish one tumor from the other. Herein, we review the literature on urothelial and prostate collision tumors and some of the special stains used to distinguish them.

The nested variant of transitional cell carcinoma (TCC-NV) is a rare neoplasm; only eight cases have been described. This report reviews the clinicopathologic features of 16 additional examples. The cases were collected from consultations received during a 13-year period. In most instances, a consultation was sought because the histologic features suggested an atypical proliferation of Brunn's nests or a lesion similar to the previously published examples of TCC-NV. Clinical data were gathered and tissues were studied to exclude prostatic cancer and adenocarcinoma. TCC-NV is characterized by the presence of irregular nests and/or tubules of transitional cells infiltrating the lamina propria without surface involvement. Neoplastic cells tend to have innocuous features but at least a few cells in every case are cytologically anaplastic. There is a marked male predominance. Synchronous or metachronous TCCs of more usual histologic make-up may occur. After a follow-up averaging 16.6 months, only three patients are known to be alive with no evidence of disease. Clinicopathologic information from our 16 cases combined with the 8 previously reported examples confirms that TCC-NV is a persistent and aggressive neoplasm notable for its innocuous appearance in histologic preparations.

We report two cases of osteoclast-like giant cell tumour of urinary bladder associated with papillary transitional cell tumours. Both cases were morphologically identical to giant cell tumour of bone. The giant cells stained strongly for acid phosphatase which was resistant to tartrate digestion, a staining reaction typical of osteoclasts. In view of the ability of urinary bladder to induce metaplastic and neoplastic bone, we believe that these tumours may represent extraosseous giant cell tumours of bone.

Tumour markers viz carcinoembryonic antigen (CEA), human chorionic gonadotrophin (HCG) in 30 cases of carcinoma breast and prostatic specific acid phosphatase (PSAP) in 30 cases of carcinoma prostate were studied by peroxidase antiperoxidase technique in paraffin blocks of tissue. Twenty three (76.7%) and 20 (66.7%) cases were positive for CEA and HCG respectively. No correlation was observed between CEA and HCG status, and histological differentiation of the tumours. All the 29 cases (100%) of adenocarcinoma prostate were PSAP positive while a single case, negative for PSAP, was of transitional cell carcinoma.

Keratin was found in more than 90% of transitional cell carcinomas of the bladder in the cytoplasma with polyclonal antibodies. Intensity increased with dedifferentiation. Cytokeratin was detected with monoclonal antibodies in more than 80%. Squamous cell carcinoma of the urinary bladder was always strongly positive for keratin and cytokeratin. CEA was found in 20% of G1 and 40% of G2 and G3 carcinomas of the urinary bladder. The prostatic epithelium markers PSA and PAP were always negative also Ca1.

5 cases of transitional cell carcinoma of the prostate, which represent 1.5% of a series of 323 consecutive prostatic carcinomas, are presented. The cases with possible prostatic involvement by contiguity from a bladder carcinoma as well as those tumors with a transitional pattern which contain prostatic acid phosphatase in the cellular cytoplasm have been ruled out to make the diagnosis. The mean age of the tumoral onset is 70 years with an identical symptomatology to that of the adenocarcinoma. In 20% of the cases it is associated with an adenocarcinoma and in 40% with a bladder carcinoma without contiguity. The mean survival is 10.6 months with 60% succumbing within the first 6 months. Our findings agree with all authors in considering this type of tumor an urothelial neoplasia.

Since 1976, we have transplanted 82 urological neoplasms into nude mice, 46 of which (56%) took. Thirty five of them (43% of the total tumors) are being serially transplanted. This rate of success seems to be better than that obtained at other institutes for both neoplasms of urogenital as well as other tissue origin. The explants basically retained the original characteristics of the native tumors not only in histological pattern but also in tumor markers, even after a long term period of heterotransplantation. However, the histological features of some tumor lines seemed to be reduced. A certain cell population was lost during repeated transplantations. Such a clonal selection may have resulted from the outgrowth of the cell population capable of adapting to the transplanted environment. Nevertheless heterotransplantation experiments in nude mice are one of the most valuable tools in various cancer research including that in the urological field since a rather high percentage of urologic malignancies take while retaining their original characteristics for a long time.

The authors utilized the technic of plastic embedding with enzyme histochemistry for the evaluation of enzymatic expression by epithelium of the lower urinary tract in humans. Alpha-naphthyl acetate esterase and acid phosphatase generally were expressed by normal and neoplastic urothelium. Expression of 5'-nucleotidase and ATPase was more restricted. Alkaline phosphatase, prominent in the transitional cells of lower mammalian species, generally was not present in human urothelium. Enzyme histochemistry has not been applied generally to the study of disease of the lower urinary tract, but this study suggests it may be of value in understanding the biology of this tissue and be of potential use in histopathologic diagnosis of diseases of this region.

The introduction of immunoperoxidase and the indirect immunoperoxidase technique made important contributions in histopathologic diagnosis of prostatic cancer. This staining can be performed on formalin-fixed paraffin-embedded tissue which is usually available. We have used this histopathologic staining technique in 56 patients. The tissues include primary and metastatic prostatic cancer tissue in addition to normal renal pelvis and bladder tissue from other patients. Our data indicate that acid phosphatase can be localized in prostatic cells but not in transitional cells. Therefore, immunohistochemical staining of prostatic acid phosphatase seems most useful to identify metastatic prostate adenocarcinoma or primary tumor and to differentiate them from intraductal prostatic transitional carcinoma or other transitional cell carcinomas.

The suggested activity of doxorubicin hydrochloride (Adriamycin), cyclophosphamide, and 5-fluorouracil as single agents in the treatment of advanced prostate and/or transitional cell carcinoma led us to examine the response to these drugs used in combination. Combination chemotherapy has the theoretical advantages of additive antitumor effect without additive toxicity to the host. One of 8 patients with Stage D, endocrine unresponsive prostatic adenocarcinoma achieved an objective response. There were five stable and one subjective responses. Only 1 patient showed progression during the initial six-week trial. Two of 3 patients with transitional cell carcinoma had an objective response. This three-drug combination was well tolerated by elderly patients and on the basis of this small series further trials are warranted.

The symptoms and physical findings in patients with transitional cell carcinoma of the prostate were similar to those in patients with prostatic adenocarcinoma. Usually the neoplasm was poorly differentiated and advanced when the diagnosis was first established. Osseous metastases were commonly osteolytic. Frequently, elevations of serum alkaline or acid phosphatase levels were associated with metastasis. Tartrate-inhibited fractions of the serum acid phosphatase were not elevated. The best form of treatment is radical ablation of the prostate and radiation therapy is next best. Because these neoplasms are not hormonally dependent, hormonal manipulation is not indicated. Prognosis for patients with this malignancy is guarded.
