Background: The pathogenesis of radiation-induced sarcomas (RISs) is not well known. In RIS, TP53 mutations are frequent, but little is known about Mdm2-p53 interaction, which is a recent therapeutic target of sarcomas. Methods: We studied the immunohistochemical expression of Mdm2 and p53 of 8 RISs. The intervals between radiation therapy and diagnosis of secondary sarcomas ranged from 3 to 17 years. Results: Mdm2 expression was more common in de novo sarcomas than RISs (75% vs 37.5%), and p53 expression was more common in RISs than in de novo cases (75% vs 37.5%). While half of the RISs were Mdm2(–)/p53(+), none of de novo cases showed such combination; while half of de novo sarcomas were Mdm2(+)/p53(–), which are a candidate group of Mdm2 inhibitors, only 1 RIS showed such a combination. Variable immunoprofiles observed in both groups did not correlate with tumor types, except that all of 2 myxofibrosarcomas were Mdm2(+)/p53(+). Conclusions: In conclusion, we speculated that both radiation- induced and de novo sarcomagenesis are not due to a unique genetic mechanism. Mdm2- expression without p53 overexpression in 1 case of RIS decreases the future possibility of applying Mdm2 inhibitors on a subset of these difficult tumors.

CT guided percutaneous fine-needle aspiration(FNA) of the liver for both cytologic and histologic examination has great value in diagnosing liver malignancy. From March, 1986 to April, 1990, 62 patients with the clinical impression of liver malignancy underwent CT guided percutaneous FNA biopsy. Of these, 43 cases were reviewed for this study, 19 were reported to be liver cell carcinoma, 2 were adenocarcinoma, 11 were reported as anaplastic cell present, and the rest (11 cases) were negative (9) or necrotic (2).
Among the 11 cases of the last group, 9 were diagnosed as liver cell carcinoma and 2 were necrotic histologically.
Retrospective review, in order to clarify the casuse of cytologic diagnostic error, of both cytologic and histologic slides of all cases showed discordance of 23% between these diagnoses and sensitivity is 93.9% and specificity is 90.9%.
The reasons were as follows :1) the lack of awareness of tumor cells of well differentiated liver cell carcinoma (4 cases), 2) missed tumor cells due to too scanty cellularity (1 case), 3) improper smear (2 cases) and no tumor cell in the cytologic smears (3 cases). In such cases, at the initiation of FNA, a correct diagnosis of liver malignancy could only be made by a combination of cytologic and histologic examinations. However after three years' experience we can conclude that cytomorphologic features of liver cell carcinoma are sufficiently distinctive from other liver malignancies to be diagnostic
Herpes simplex virus type 1 and 2(HSV-1, HSV-2) are the ubiquitous human pathogens responsible for a variety of afflictions, HSV-2 is one of the viruses that were suspected of promoting carcinogenesis in the uterine cervix.
Certainly, there is a need for the more sensitive and accurate laboratory techniques for HSV detection.
We examined total 80 cases of smears including 17 Tzanck smears of skin and 63 cases of Papanicolaou smears from total 77 patients with clinical impression of herpetic infections, from September, 1985 through August, 1989.
Immunohistochemical typings for HSV-1 and HSV-2 were performed together with routine cytologic findings and compared The results are as follows : 1) patients were 9 males and 33 females, and age distribution was between 5 and 71 years 2) Subjective symptoms such as ulceration, vesicle, vaginal discharge, pruritus, and pain were complained in 36 patients and 38 cases were genital herpes. Recurrence was noted in 11 cases.
3) Positive results were obtained in 42 among 80 cases.
4) Both routine cytology and imunohistochemical staining were positive in 13 cases and in 24 cases only immunohistochemical staining were positive. 5 cases were positive only in routine cytologic smears.
5) The cases that immunocytochemical stain had been performed were 37 cases, which were all positive in type 2, Among the above 37 cases, type 1 also were positive in 5 cases.
The results show that the immunoperoxidase technique is one of the rapid and reliable method to confirm the herpetic infection when suspected and that it is particularly useful when the Papanicolaou smear findings are equivocal
