Nuclear DNA content of 32 cases of prostate adenocarcinoma diagnosed 1986-1991 was determined by flow cytometry, with the use of paraffin-embedded archival tissue. The present study was done to define the relationship between clinical stage, histopathological grade, and DNA ploidy. Aneuploidy was found in 10(31.3%) cases including 7 cases of near-tetraploidy. Among diploid tumors, 36.4% were localized disease(stage A and B), 13.6% were characterized by invasion outside the prostate(stage C), and 50.0% showed distant metastasis(stage D). Among aneuploid tumors, 10.0% were stage B, 50.0% stage C, and 40.0% stage D. The degree of glandular differentiation was characterized by the Gleason score and the percentage of sampled tissue involved by carcinoma was graded by Dhom's method. Apparent correlation was found between Gleason grade and Dhom grade(P<0.05). All 13 tumors with a Gleason grade I(score of 2 to 5) were diploid. Four of 9 tumors with a Gleason grade II(score of 6 to 7) were aneuploid(near-tetraploidy 33.3%, aneuploidy 11.1%) and 60.0%, of tumors with a Gleason grade III(score of 8 to 10) were aneuploid(near-tetraploidy 40.0%, aneuploidy 20%). The percentage of aneuploid cases increased with advanced clinical stage, but the relationship between aneuploidy versus clinical stage was not significant. However, it can be concluded that DNA ploidy correlates well with Gleason grade(p<0.05), which may have predictive prognostic value for prostate adeno-carcinomas.

The purpose of this study is to evaluate the change of mucosal immunity in gastric diseases. A quantative analysis of IgA and secretory component(SC) in gastric diseases by immunohistochemical method was performed in 110 specimens. The results are as follows: 1) In normal gastric mucosa, all of 10 cases revealed a negative reaction to antihuman SC but 4 cases were positive for IgA. 2) In chronic superficial gastritis and chronic atrophic gastritis with intestinal metaplasia, the metaplastic cells except for the goblet cells were positive for both IgA and SC. 3) The dysplastic cells were also positive for both IgA and SC, and the regenerating cells in ulcer as well. 4) All of the well differentiated or moderately well differentiated adenocarcinomas showed positive reactions to antihuman IgA and antihuman SC, and the intensity appeared to be stronger in the former. However, among 10 cases of poorly differentiated adenocarcinoma SC was not demonstrated in 5 cases, and no IgA was present in one case. In 10 cases of signet ring cell carcinoma, 6 cases revealed a negative reaction to antihuman IgA and 6 cases to antihuman SC. The above results suggest that the secretory immunity is not essential in normal gastric mucosa. The intestinal metaplasia in chronic gastritis is considered as an adaptive response to chronic inflammation. The degree of differentiation in adenocarcinoma may be related to the mucosal immunity.

6.Study on the Stromal Response of Colon Cancer in Relation with the Stage of the Cancer.
Korean Journal of Pathology 1987;21(2):82-89
Total 74 cases of colon cancer were examined in the Inje Medical College, Pusan Paik-hospital, which were collected from 1979 to the April 1986. The stromal histopathological findings are as followings; 1) The highest frequency of the good reactions of the four parameters of the stromal response (i.e., good general stromal reaction, peripheral tumor disintergration, and each inflammatory cell infiltration and fibrous proliferation alone) was found in Dukes class B1 and the least frequency in Dukes C1. The good general stromal response and the peripheral tumor disintegration are more closely related with the stage than the other two parameters. They are about 60% in class B1, 30% in class B2 and C2, and 20% in class C1. 2) The insistent poorest stromal response of the Dukes C1 in all parameters may be explained from the fact that the cancer cells of this particular stage are very aggressive biologically because the cancer cells are capable to invade the regional lymph nodes before the main tumor can infiltrate all through the layers of the wall. 3) Among the four types of the colon cancer, the better stromal reactions are observed in more than half of the cases of the well and moderately differentiated adenocarcinoma while this trend is completely opposite in the mucinous and poorly differentiated types. 4) The above findings indicate that how closely the stroma influences upon the progress of the colon cancer, or how closely it represents the status of the individual immunological force.

BACKGROUND: The purpose of this study was to examine the reproducibility of both the diagnosis of endometrial hyperplasia (EH) or adenocarcinoma, and the histologic grading (HG) of endometrioid adenocarcinoma (EC). METHODS: Ninety-three cases of EH or adenocarcinomas were reviewed independently by 21 pathologists of the Gynecologic Pathology Study Group. A consensus diagnosis was defined as agreement among more than two thirds of the 21 pathologists. RESULTS: There was no agreement on the diagnosis in 13 cases (14.0%). According to the consensus review, six of the 11 EH cases (54.5%) were diagnosed as EH, 48 of the 57 EC cases (84.2%) were EC, and 5 of the 6 serous carcinomas (SC) (83.3%) were SC. There was no consensus for the 6 atypical EH (AEH) cases. On the HG of EC, there was no agreement in 2 cases (3.5%). According to the consensus review, 30 of the 33 G1 cases (90.9%) were G1, 11 of the 18 G2 cases (61.1%) were G2, and 4 of the 4 G3 cases (100.0%) were G3. CONCLUSIONS: The consensus study showed high agreement for both EC and SC, but there was no consensus for AEH. The reproducibility for the HG of G2 was poor. We suggest that simplification of the classification of EH and a two-tiered grading system for EC will be necessary.

Association of the hepatoid and choriocarcinomatous components in adenocarcinoma of the stomach is extremely unusual and raises a possibility of new approach understand the histogenesis of gastric hepatoid adenocarcinoma. This paper describes a Borrmann type III adenocarcinoma of the stomach with both choriocarcinomatous and hepatoid components in composite tumor pattern in a 50-year-old man. Tubular arrangement of differentiated embryonalcarcinoma was encountered in choricarcinomatous and hepatoid areas, which showed strong immunoreactivity to beta-HCG and AFP, respectively. The findings suggest that gastric adenocarcinoma may have a potential of differentiation toward embryonal carcinoma. from which both choriocarcinoma and hepatoid variant of gastric adenocarcinoma may develop by retrodifferentiation.

As flow cytometric analysis using paraffin-embedded tissue was developed by Hedley et al in 1983, retrospective study with large amount of archival material was possible. Many literatures reported that the result of paraffin embedded tissue was compatible with that of fresh tissue. We compared the DNA histograms of 26 cases of colorectal adenocarcinoma in which the analysis was done in both fresh and paraffin-embedded tissues. Aneuploidy in fresh and paraffin-embed-ded tissues was 73.0% and 50.0%, respectively. The concordance rate of fresh and paraffin-em-bedded tissues was 76.8% and six interpreters were agreed in 73.0% of the cases. Because flow cytometric DNA analysis using fresh tissues can detect more aneuploid population than in paraffin-embedded tissue, the former is strongly recommeded in DNA ploidy study. Also careful observation using standard criteria may improve the interpretation of DNA histogram.

10.Obstructive Colitis: A Clinicopathologic Analysis of 7 Cases.
Korean Journal of Pathology 1996;30(12):1116-1122
Obstructive colitis is an ulceroinflammatory lesion of the large intestine at a distance proximal to the obstructing or potentially obstructing lesion of any etiology. It has been suggested that a rise in the intraluminal pressure related to the obstruction results in a fall in the intramural blood flow with subsequent ischemic necrosis. We examined 7 cases of surgically resected obstructive colitis associated with distal constrictive adenocarcinoma of the large intestine. Two cases of the obstructive colitis were radiologically suspected prior to surgery either as a separate tumor mass or diverticulosis, and another case was suggested to be a tumor seeding by colonoscopy. Grossly, five cases presented with single or multiple, shallow, well-demarcated ulcerative lesions, and the remaining two were featured with a segmental ulcerative lesion the with pseudopolypoid area. The ulceroinflammatory lesions were separated from the distal obstructive carcinoma by a skipped zone of relatively normal mucosa measuring 4-43 cm. The proximal colon to the obstructive lesions were obviously dilated except in one case. Microscopically, mucosa and submucosa were replaced by granulation tissue, and showed inflammatory cell infiltration and fibrin exudates. Muscle coat often accompanied ischemic contraction. Fissuring was noted in one case. The recognition of these lesions prior to or during surgery is stressed based on the morphological features corresponding to an ischemic change in the proximal mucosa to the primary obstructive lesion.
