Abstract
DNA contents from single cells at interphase and division were analysed in histological sections and in imprints from 73 breast cancer specimens. Fetal livers from 18 terminations of normal pregnancies provided the standard for truly mitotic prophases, metaphases and telophases. The reliability of DNA quantities from image microphotometry was improved using paraffin-embedded tissue samples from which 4, 8 and 15 microns slices were Feulgen stained. Imprinted replicas from the mirror surface of each freshly cut specimen provided matching domains and represent the crucial approach in this project. A close positive relationship was observed between interphase nuclei in 8 microns sections and their imprinted counterparts (r = 0.992; n = 73). Interphase nuclei in 4 microns sections yielded insufficient DNA contents when compared with the imprints (r = 0.815; n = 21) and with endogenous lymphocyte nuclei. This 2 cDNA standard also calibrated 232 mitotic figures to 3.91 +/- 0.01 c in 15 microns sections from fetal liver. Prophases, metaphases and telophases were slightly scattered (coefficient of variation = 0.04 each). The 0.09 c deficiency to plain 4.0 c was read as an artifact from sectioning. However, the methodical bias did not challenge the most irregular DNA distribution profiles recorded from chromosome division figures (CDFs) in 15 microns sections of breast cancers. Poorly differentiated and aggressive breast cancer (Auer type IV, Zetterberg type A) exhibited a 4.5 c exceeding rate of 82.24% from a total of 752 CDFs in 10 randomly selected cases. Well differentiated, slowly growing cancer with diploid interphase nuclei (Auer I, Zetterberg D) surprisingly showed a 4.5 c exceeding rate of 29.26% from a total of 173 mitoses and CDFs in 10 randomly selected cases. The bulk of data beyond the mitotic 4.0 c level discriminates biological bias from methodical impairment. We concluded that 8 microns sections are sufficient for human interphase nuclei, whereas a depth of 15 microns preserves intact mitoses and CDFs.

Abstract
PURPOSE We have previously shown that the intensity (graded semiquantitatively as 1-4+) of tissue prostate-specific acid phosphatase (PSAP) staining determined immunocytochemically in a cohort of prostate carcinoma patients from Radiation Therapy Oncology Group Protocols (RTOG) protocols 75-06 and 77-06 correlated with survival. The extent of this staining was heterogeneous and was estimated. The extent of staining was not found to be significantly associated with survival. We undertook the present quantitative study to see if the improved precision and reliability of measurement of the intensity and extent of prostate specific acid phosphatase staining would confirm and extend our previous observations. METHODS AND MATERIALS Patient cohorts representative of the entire group were obtained from RTOG 75-06 plus 77-06 and 83-07. The RTOG 77-06 plus 75-06 patients (No-Hormone population) did not receive preradiation hormonal therapy. RTOG 83-07 patients (Prehormone population) received one of two types of preradiation chemical androgen ablation. In this study, histologic slides of tumors were immunocytochemically stained for PSAP by the peroxidase-antiperoxidase (PAP) technique using diaminobenezidene (DAB) as a substrate and hematoxylin as a nuclear counterstain. The intensity and extent of immunocytochemical PSAP staining (IPSAP stain) was quantified using our dual wavelength and batch mode image process technique. RESULTS Our study of 151 cases confirmed that overall survival of patients in both populations was positively correlated with the intensity and extent of IPSAP stain. Results of the two studies were similar. The statistical significance of the relationship of both extent and intensity was greater in the cohort from protocol 83-07, which was the patient group receiving pretreatment with hormones. In a Cox multiple regression analysis including clinical stage, Gleason and M. D. Anderson grades, and the cohort of patients (Prehormone or No-Hormone group) as covariables, both the intensity and extent of the IPSAP stain significantly correlated with survival along with M. D. Anderson grade of the tumor. CONCLUSION Quantitative image analysis of the IPSAP stain predicts survival in patients treated with external beam radiotherapy with and without prior hormonal therapy.

Abstract
The present study compares the prognostic potential of tumour grade and DNA ploidy status in patients with advanced-stage prostatic cancer. Two outcome groups were selected on the basis of time to progression and survival after orchiectomy. A poor-outcome group consisted of 32 therapy-resistant patients who experienced disease progression during the first year after orchiectomy and subsequently death due to prostatic cancer during the following year. A good-outcome group consisted of 27 therapy-responsive patients who showed disease regression and no signs of progression during a 3 year follow-up. The primary tumours were graded twice according to WHO and Gleason classification systems by two pathologists. Final agreement between the pathologists was obtained after a consensus meeting. The analysis revealed no prognostic importance of the two histological classification systems (P = 0.62 and P = 0.70) and disclosed weak inter- and intra-observer reproducibility (kappa < 0.70). DNA ploidy analyses were performed by image cytometry on formalin-fixed, paraffin-embedded samples of the primary tumours. Overall, 48% of the tumours were diploid, 20% tetraploid and 32% anueploid. DNA ploidy status did not discriminate between the two outcome groups (P = 0.46). Histological grade and DNA ploidy showed no prognostic importance in patients with prostatic cancer and skeletal metastases.

Abstract
A total of 115 articles on prostate cancer were reviewed for data on the prognostic value of DNA content in the tumor cells. In 44 series, data pertinent to this review were found. There was no consensus in the literature with respect to methods of analysis of DNA content or definitions of subclasses of DNA content such as categories of ploidy. The DNA content of prostate cancer cells was strongly related to tumor grade and stage. When analyzed as a single parameter in univariate analyses, the DNA content had a prognostic value with respect to overall or disease-specific survival. In multivariate analyses the additional prognostic value of the DNA content was less convincing when analysed with tumor grade and stage. The prognostic data from univariate and multivariate analyses available in the literature were mainly derived from patients with advanced disease and data on localized, potentially curable disease were scanty and conflicting.

Abstract
Prostatic intraepithelial neoplasia (PIN) is regarded as the most important premalignant lesion of prostatic epithelium. The aim of this investigation was to find clues to formal pathogenesis of prostatic cancer. For this purpose DNA ploidy (determined by means of image cytometry [ICM] using 4-microns-thick Feulgen-stained paraffin sections) of PIN and invasive carcinoma was compared. Prostatic tissue of 72 patients (mean age, 67.5 years; 82 areas with carcinoma and 71 areas with PIN) was examined. In 44 cases PIN and carcinoma were coexistent in the same prostates, the PIN grade being high in 77% of these cases (P < .05). In higher-grade PIN and higher-grade carcinoma the c-values, 2.5c-exceeding-rate, and aneuploidy rate increased (P < .01). Carcinomas associated with diploid PIN (either low or high grade) showed diploidy and aneuploidy in an equal number of cases, whereas 70% of aneuploid PIN cases (all high grade) were associated with aneuploid invasive carcinomas (P < .01). Conversely, in 71% of the cases with aneuploid carcinoma the coexistent PIN (either low or high grade) was diploid. Our findings show that aneuploidy can be acquired at a preinvasive stage of carcinogenesis in the prostate and suggest that aneuploid high-grade PIN might be regarded as a precursor of some but not all aneuploid prostatic carcinomas. Image cytometry analysis seems to be a promising method for further subclassification of high-grade PIN lesions into groups with putatively lower or higher risk. However, further investigation is necessary to confirm the clinical importance of these results.

Abstract
Matrix metalloproteinase (MMP) expression was investigated in patients with prostatic adenocarcinoma and benign prostatic hyperplasia (BPH). Forty-one men were studied: 26 had histologically proven prostate cancer, with 14 (54%) showing metastatic disease; 15 patients had BPH. Prostatic tissue was obtained from transurethral resection and needle core biopsies; gelatinolytic activity was determined by zymography. Seven gelatinolytic bands were detected, with molecular weights ranging from > 100 kilodalton (kDa) to 29 kDa. Nine of 14 patients (64%) with skeletal metastases had 92 kDa activity, present in only two of 12 patients (17%) with a negative bone scan, and absent in BPH. The 92 kDa gelatinolytic activity was expressed in 73% of aneuploid tumours compared with 20% of diploid tumours. A 97 kDa gelatinase was expressed in 80% of BPH samples and 23% of carcinoma patients. Enzyme bands of 72, 66 and 45 kDa were equally expressed in malignant tissue, irrespective of metastatic status, but were expressed in fewer BPH patients. The 97, 92, 66 and 45 kDa enzymes were identified as being pro-MMP-9 sequences by Western blotting, using a specific antibody directed against the pro sequence of the mature protein. MMP activity appeared to be increased in malignant prostatic tissue compared with BPH. Pro-MMP-9, in its 92 kDa form, was shown to be exclusively expressed by malignant prostatic tissue, and in particular by tumours that exhibited the aggressive and metastatic phenotype.

Abstract
To determine whether the prostate specific antigen (PSA) and prostatic acid phosphatase (PAP) immunoreactivities in prostatic carcinoma are reliable prognostic factors, the PSA and PAP immunohistochemical distribution was examined in needle biopsy specimens of 80 patients with advanced prostatic carcinoma. Our results indicated a higher cancer-specific survival rate in patients with a greater PSA or PAP immunostaining. Furthermore, a multivariate analysis of possible prognostic factors, that is patient age, clinical stage, Gleason score, serum PAP, PSA and PAP immunostaining scores, and the initial treatment, has confirmed that the difference in PAP immunoreactivity is the most important prognostic factor (p < 0.01) for advanced prostatic carcinoma, with the Gleason score (p = 0.06), clinical stage (p = 0.09) and PSA immunoreactivity (p = 0.48) being the second, third and fifth prognostic factors, respectively.

Abstract
The relation of prostatic intraepithelial neoplasia (PIN) or ductal dysplasia and the development of invasive prostate cancer is not clear. PIN, especially high grade, is usually associated with coexisting invasive cancer. Although some investigators have identified micro foci of invasive cancer evolving from PIN, the two are usually anatomically separated. Because of these distinct anatomic patterns, many investigators have concluded that PIN represents a "field effect" or marker of potential cancer progression, and is not directly involved in or leads to the development of invasive prostate cancer. We measured the DNA content in 49 foci of invasive cancer and 87 foci of PIN identified in 34 radical prostatectomies containing both PIN and invasive cancer. In addition, we examined 13 prostatectomies and 5 TUR specimens containing only PIN. We found that the majority of low grade PIN had normal or diploid range DNA and that approximately half of the high grade PIN were abnormal or aneuploid. Prostates with coexisting diploid range PIN and invasive cancer had an approximately equal number of diploid range and aneuploid invasive cancers. Conversely, almost all of the aneuploid PIN (usually high grade) had coexisting aneuploid invasive cancers. This would support the hypothesis that events in the progression of prostate cancer may be operative in both the development of PIN and invasive cancer.

Abstract
BACKGROUND A characteristic feature of prostatic adenocarcinoma is its great variation in biologic behavior. This variation and the observation that most carcinomas are of intermediate grade make standard histologic grading of limited value in determining the prognosis of a patient. METHODS DNA quantitation with the use of computer-assisted image analysis on Feulgen-stained nuclei was performed on the metastatic lymph nodes from patients with Stage D1 prostate carcinoma to determine whether ploidy was a useful predictor of survival or progression. The Gleason histologic score of the primary tumor, the number and extent of lymph node metastases, and the progression and survival intervals were documented. Treatment modalities included pelvic lymph node dissection, radical prostatectomy, external beam radiation therapy, and iodine 125 implantation. RESULTS DNA ploidy quantitation showed that 65% (33 of 51) of cases were aneuploid, 2% (1 of 51) were tetraploid, and 33% (17 of 51) were in the diploid range. Progression to Stage D2 disease occurred in 76% of the patients with aneuploid cases and 53% of those with cases in the diploid range. CONCLUSION There was a significant difference in progression between the two ploidy groups (Cox regression analysis, P less than 0.05).

Abstract
Staging of prostatic adenocarcinoma is a systematic classification of the extent of disease based on clinical and pathologic criteria. This classification determines treatment and reflects ultimate expected clinical outcome. The technologic changes in diagnostic modalities need to be incorporated into the staging classification and a better assessment of biologic hazard of each individual tumor needs to be developed to further refine current treatment of prostate cancer.

Abstract
Analytical flow cytometry was used to study circulating prostate specific antigen (PSA)-positive cells in 40 consecutive patients with newly diagnosed, untreated prostate cancer; 25 patients (63%) had metastatic disease confirmed by a positive bone scan. Cell suspensions were prepared for each patient from both the primary tumour and peripheral blood samples. The cells were stained with a monoclonal antibody against PSA, and analysed by flow cytometry; PSA-positive cells were sorted according to their immunofluorescence and light scatter properties. The cellular deoxyribonucleic acid (DNA) content of each specimen was also analysed to establish ploidy status. PSA-positive cells were detected in the peripheral blood of 33 patients (83%). The presence of these cells in the circulation showed a higher degree of sensitivity and specificity in predicting positive bone scans than did serum PSA levels. Circulating PSA-positive cells may represent either a subpopulation of tumour cells with distinct metastatic properties or, alternatively, host immunocytes which take up PSA in an active or passive manner.

Abstract
We longitudinally followed serum prostate specific antigen (PSA) levels in 48 patients who were treated with either orchiectomy, monthly luteinizing hormone-releasing hormone injection or continuous diethylstilbestrol for stage D2 prostate adenocarcinoma and achieved an objective response. Of the patients 34 had clinical evidence of disease progression (median remission duration 19 months). Median length of followup for the 14 patients who remained in remission was 42 months. Pretreatment performance status, pretreatment extent of metastases as measured by a bone scan and post-treatment nadir PSA level were univariately correlated with remission duration. After adjustment for the 2 former pretreatment variables, a highly significant independent effect of the nadir PSA level on remission duration persisted. Patients whose post-treatment nadir PSA level decreased below 4 ng./ml. had a significantly longer remission duration than those whose nadir PSA remained elevated (median 42 versus 10 months, p less than 0.0001). No cases were observed to progress (as defined by our criteria independent of PSA level) while the serial post-treatment PSA levels continued to decrease or remained at a plateau after reaching the nadir. The time at which the PSA began to increase once the nadir was reached predated objective evidence of progression in all patients except 2 in whom the 2 events occurred simultaneously (mean lead time 7.3 +/- 5.0 months). We conclude that following serial PSA levels in patients treated with androgen ablation for metastatic prostate cancer can aid in distinguishing favorable from nonfavorable responders early in the course of therapy and greatly assist in monitoring for progression.

Abstract
Carcinoma is found unexpectedly in approximately 10% or more of the 400,000 prostatectomies performed annually in the United States. Patients with Stage A2 carcinoma die of their disease in only 35% of the cases. To alter the course of disease in these patients, 65% of Stage A2 patients may be treated unnecessarily by radical prostatectomy, radiation therapy, or hormonal therapy. An accurate method to predict the outcome of patients with Stage A2 carcinoma is needed. Histologic sections from 18 patients with Stage A2 prostatic carcinoma followed without further treatment until progression, or followed without progression, were evaluated by several investigators who did not have knowledge of patient outcomes and who employed standard pathologic grading systems as well as morphometric, cytophotometric, flow cytometric, and immunohistochemical techniques. Outcome was predicted correctly by random sampled absolute (17 of 18 cases) and relative (16 of 18) nuclear roundness factor (NRF), tumor volume expressed as percent of specimen (13 of 16), primary (13 of 18), secondary (14 of 18), sum (15 of 18), and worse (14 of 18) Gleason grades and prostate-specific antigen immunohistochemical findings (13 of 18) that produced statistically significant separation of the two groups. Significant separation was not obtained with Mostofi's pattern, nuclear, sum, and worse grades, Johns Hopkins' grade, absolute tumor volume, nuclear DNA content measured by image cytophotometric study of Feulgen-stained histologic sections and flow cytometric study of propidium iodide-labeled suspensions of nuclei obtained from paraffin blocks, nonrandom sampled NRF of worse and most prevalent neoplastic areas, and prostatic acid phosphatase and peanut agglutinin immunohistochemical study. NRF measured by a random technique best predicted outcome in these patients with A2 prostatic carcinoma and should be evaluated prospectively as a means for selecting patients who require therapy.

Abstract
The nuclear DNA content of prostate cancer specimens, both needle biopsies and aspiration biopsy specimens as well as transurethral resection (TUR) chips and radical prostatectomy specimens, can now be reliably measured by standardized methods of flow and static image cytometry. For prostate carcinomas of every clinical stage (A1-D2), DNA diploid tumors have a better prognosis than tumors of a similar stage and grade which are non-diploid. Of particular importance to this symposium is the fact that DNA diploid stage D1 and D2 tumors treated early by androgen deprivation generally have a remarkably good prognosis. In contrast, those patients with DNA non-diploid tumors progress early despite androgen deprivation. Such a result suggests that DNA ploidy can be used to identify prostate cancers which are potentially sensitive to hormonal manipulation. Additional investigations from several groups indicate that early stage prostate malignant lesions, for example stages A1, A2, B1, and B2, are generally DNA diploid (about 75%). Swedish data suggest a steady progression of prostate cancer from early diploid to tetraploid, to non-tetraploid aneuploid, to multiple stemline aneuploid tumors with time and advancing stage. Taken together, these data suggest that the earliest detectable prostate carcinomas should be overwhelmingly DNA diploid. A large majority of these patients with early tumors should be candidates for "chemoprevention" by pharmacologic methods which reduce the effective androgen stimulation of prostate tumor cells.

Abstract
Modal DNA-values were assessed with flow cytometry in 269 patients with newly detected untreated prostate cancer. One hundred and seventy-two patients with low-grade, low-stage, non-metastasized cancers were followed without treatment and in this group initial tumor ploidy had no prognostic value. Ninety-seven patients with clinically more advanced prostate cancers were subjected to endocrine therapy and in this group ploidy was prognostic regarding cancer-related survival.

Abstract
To determine whether prostatic acid phosphatase (PAP) immunoreactivity in prostatic adenocarcinoma is a reliable prognostic factor, the PAP immunohistochemical distribution has been examined in 78 prostatic carcinoma cases. The intensity of PAP immunostaining was graded from 0 to 2, and the scores of the primary and the secondary staining patterns were added to assess the extent of the PAP expression in needle biopsy specimens. As a result, a higher cancer-specific survival rate was observed in patients showing a greater PAP immunostaining (P less than 0.01). Further, a multivariate analysis was made of possible prognostic factors (age, stage, Gleason score, serum PAP, PAP-immunostaining score, and the initial treatment) to estimate the extent of their impact on cancer-specific survival. Results have confirmed that the difference in PAP immunoreactivity is an excellent, independent prognostic factor for prostatic carcinoma.

Abstract
We selected for a prospective surveillance study 167 patients with untreated grades 1 and 2 prostate cancer. The tumors were classified regarding modal deoxyribonucleic acid value (ploidy) by flow cytometry, cytological grade by transrectal fine needle aspiration biopsy and local tumor stage. Of the patients 146 could be evaluated. Mean followup was 50 months. The initial ploidy was statistically correlated to cytological grade but not to initial local tumor stage, prostatic acid phosphatase activity or patient age. Initial ploidy and cytological grade had a prognostic value regarding local tumor progression when considered as single predictors and in combination. Two patients with diploid and 8 with nondiploid tumors initially had metastases during the surveillance. Five patients (1 with diploid and 4 with nondiploid disease) died of prostatic cancer. Modal deoxyribonucleic acid value and cytological grade were of prognostic value in untreated prostate cancer.

Abstract
Repeated fine needle aspiration biopsies of the prostate were taken during a period of 24 months or more from 84 patients with untreated prostate cancer. Serial followup regarding modal deoxyribonucleic acid values and cytological differentiation of the tumor cells was possible in 72 and 78 patients, respectively. During followup the modal deoxyribonucleic acid values in the tumor cells changed towards an increased aneuploidy in 17 patients and the cytological differentiation decreased in 18. These findings of a change in modal deoxyribonucleic acid values and cytological differentiation of prostate cancer cells during the course of untreated patients support the concept of a gradual dedifferentiation of prostate cancer.

Abstract
The nuclear DNA distribution pattern of the neoplastic parenchymal cells of 100 conventionally formalin-fixed and paraffin-embedded specimens from pancreatic adenocarcinomas and from 8 specimens of chronic pancreatitis was assessed by means of image cytometry. All material originated from pancreatic restrictions. Evaluable DNA histograms could be obtained for 77 carcinomas, and clinical data were available for 71 of these. In these 71 specimens, the nuclear DNA ploidy pattern was also investigated by means of flow cytometry. In 76 of the 77 cases, the image-cytometric DNA ploidy pattern obtained showed a "nondiploid" distribution with modal values as high as 8.5 c. In 21 cases, the neoplastic cells showed modal values in the "triploid" region. The analogous 71 flow-cytometric DNA histograms could only be evaluated in 50 cases because of excessively high amounts of background and/or excessively broad peaks. In 47 cases, the nuclear DNA histogram was nondiploid according to both techniques. The patients with carcinomas whose cell nuclei showed a triploid DNA distribution showed a significantly shorter survival time than those with tumor cell populations of nontriploid DNA distribution patterns. In the 8 specimens of chronic pancreatitis, the parenchymal cells were all equipped with nuclei showing diploid DNA distribution patterns.

Abstract
DNA-ploidy in 143 cases of prostatic carcinoma was assessed by flow cytometric analysis of paraffin-embedded biopsy material. The majority of the tumours (64.3%) were diploid, but in advanced stages the DNA-aneuploidy rate increased from 15 to over 60%. No hypoploid tumour was observed and most of the hyperploid tumours were near-tetraploid. DNA-aneuploidy was also strongly related to histological grade. Survival analysis using Cox multivariate regression model revealed that low histological grade (high Gleason score), advanced stage and increased level of prostatic acid phosphatase were the most important prognostic factors. DNA-ploidy per se did not contribute independently as a predictor of survival.

Abstract
Two biopsies of intraductal and invasive lobular carcinoma of the breast and 11 biopsies of intraductal and invasive carcinoma of the breast were examined by automated micromensurative techniques for mean nuclear area of carcinoma cells in intraductal and in invasive compartments. The nuclei of invasive carcinoma cells tended to be smaller when they invaded stroma as single cells or as "thin strands" than when they invaded as part of large sheets of cells. Cells in direct apposition with the stroma usually had smaller nuclei than cells which were found centrally in large confluent sheets of cells. Intraduct carcinoma cells approached, in size, invasive cells which formed confluent sheets, rather than cancer cells which invaded as single cells. The nuclei of cells which invaded in small groups were usually darker than those of cells in confluent sheets, which were usually more vesicular.

Abstract
The reliability of microspectrophotometric (MSP) and flow cytometric (FCM) nuclear DNA measurements has been studied in 50 human breast adenocarcinomas. The tumor material was obtained by means of fine-needle aspiration biopsy, and all samples except one were found to be highly representative. The results confirm earlier observations that a good correlation exists between modal value (MV) determined by MSP and DNA index (DI) determined by FCM. However, when tumors were classified into low and high malignant variants according to FCM/DI, FCM/S-phase percentages, and MSP histogram types, the concordance was less pronounced. This was found to be due mainly to the fact that in near-diploid tumors a discrepancy exists between MSP and FCM ploidy, as well as between MSP distribution pattern and the estimated percentages of cells in the S-phase region. Another source of discrepancy was observed in tumors with stemlines in the normal tetraploid region, including cells with highly scattered aneuploid DNA values. These tumors were judged by MSP as aneuploid/high malignant and by FCM as euploid/low malignant. In view of this discrepancy, we conclude that the simple determination of the stemline position by MSP/MV or FCM/DI is not sufficient for adequate cytochemical malignancy grading of breast carcinomas. We suggest that a combination of ploidy and percentage of cells scattered outside the modal peaks is a more sensitive method for optimal cytochemical malignancy grading in breast carcinomas.

Abstract
DNA content of prostate tumour cells has been measured by flow cytometry of cell suspensions prepared from fixed tissue by an enzyme disaggregation technique. Two classes of tumours have been identified: diploid tumours, with a DNA content similar to benign cells and aneuploid tumours with grossly abnormal DNA values. The prognosis for the aneuploid tumours was significantly worse than diploid tumours (P less than 0.001). When ploidy is combined with histological grading, here using the Gleason numerical system, it is possible to predict which patients, whatever their age at diagnosis, will die from their tumour and which patients will probably die before their tumour kills them. With these facts it is possible to select patients for active or expectant treatment.

Abstract
For diagnostic purposes 14 histologically benign, 15 dysplastic, and 16 malignant squamous epithelial lesions were subjected to DNA cytophotometry. Results were computed according to an algorithm for DNA diagnosis and grading of malignancy. In cases of unequivocally malignant or benign lesions all DNA diagnoses agreed with the histologic diagnoses. In one case the allegedly faulty DNA diagnosis of cancer was proven to be correct on clinical follow-up. Within the group of histologically mild to moderate dysplasias the algorithm identified four cases as malignant that were proved to be malignant either in the follow-up or at another site of the same lesion. With the aid of the DNA malignancy grade two groups of patients with squamous epithelial carcinomas of the larynx could be discerned with a highly significant difference according to their survival times.

Abstract
Eighty patients with prostate carcinoma underwent fine-needle aspiration biopsy for cytologic grading and DNA-single-cell fluorescence photometry before and at 6-month intervals after endocrine treatment. The histograms of DNA values showed single peaks and bimodal and scattered distributions which correlated to the different tumor grades before therapy. The DNA values were significantly different from the controls with benign prostatic hypertrophy. After start of therapy, regressive changes of the DNA-histograms were increases of diploid and hypodiploid DNA values and disappearance of secondary peaks. Progressive changes were increased scattering of DNA values and appearance of secondary peaks. Progressive changes in the histograms were closely related to clinical remission and stable disease, but related poorly to clinical progression. The survival correlated with the pretherapeutic DNA-histograms and with the DNA-median, third-quartile, and maximum parameters.

Abstract
The cellular DNA content in fine-needle prostatic aspirates from 500 untreated patients was determined by flow cytofluorometry. According to the DNA patterns diploid, tetraploid, and non-tetraploid aneuploid cases were identified. In 301 cytologically benign cases more than 90% showed diploid DNA patterns. Among 166 carcinomas the incidence of aneuploid DNA values increased with the degree of anaplasia, ie, 44% in well-differentiated, 78% in moderately differentiated, and 97% in poorly differentiated tumors. In aneuploid cases of well-differentiated carcinomas almost exclusively tetraploid DNA patterns were observed, while in poorly differentiated carcinomas about 80% showed non-tetraploid aneuploid DNA distributions. Among aneuploid cases of moderately differentiated carcinomas 2/3 were tetraploid and 1/3 non-tetraploid aneuploid. Morphologically similar tumors may thus be separated by the DNA profiles. The biological significance of these results must be further evaluated by clinical follow-up of the patients.

Abstract
The diagnosis and detection of genitourinary cancer covers a broad range of physical signs and instrumental observations which are not necessarily diagnostic. The primary diagnosis in most entities remains dependent upon histologic confirmation. Adenocarcinoma of the prostate is the most common, and at times, most difficult urogenital cancer to diagnose and detect. Many newer techniques today are designed to evaluate the stage of disease, and to detect heretofore occult metastatic foci. Immunologic assays may be of future prognostic value.

Abstract
In a continuing search for karyotypic changes characterizing various human cancers we have examined in detail with Q and G banding techniques the chromosomal constitution of a metastatic cancer of the prostate. The results obtained with these techniques present not only what is to our knowledge the first description of the chromosome constitution in cancer of the prostate but also the first observation of an isochromosome 17 marker in a cancerous state other than a blood disease. Only further studies on the precise identification of individual chromosomes in other cancers will reveal the significance of this marker in human cancer.
