1.Nuclear Expression of Mutant p53 protein in Transitinal Cell Carcinoma of the Bladder Detected by Immunohistochemistry: The Correlative Study with Proliferating Cell Nuclear Antigen Expression, Nucleolar Organizer Regions per Nucleus and Flow cytometric P.
Korean Journal of Urology 1994;35(5):477-491
We examined the nuclear overexpression of p53 protein by immunohistochemical analysis of the deparaffinized tumor tissue specimens from 45 patients with transitional cell carcinoma of the bladder. The data were then correlated with conventional prognostic variables such as histologic tumor grade, stage and DNA ploidy. In addition, we related the expression of the 53 protein to indicators of cellular proliferative activity, including proliferating cell nuclear antigen(PCNA), mean number of silver-binding nucleoar organizer regions(AgNORs) per nucleus, flow cytometric S-phase fraction(SPF) and proliferation index(PI). Survivals of the patients according to mutant p53 protein expression, stratified by histologic tumor grade and stage were analyzed.None of the urothelial cells from normal bladder specimens showed nuclear expression of mutant p53 protein. Mutant p53 protein expression was not associated with histologic tumor grade, stage, flow cytometric SPF and PI, but there was an association between mutant p53 protein expression and flow cytometric DNA ploidy with marginal statistical significance(p=0.0892) There was statistically significant difference of mutant p53 protein expression between low and high AgNORs counts per nucleus(p=0.0108), but here was no significant correlation between mutant p53 protein expression and PCNA expression rate. Using Kaplan-Meier analysis, we could not identify the statistically significant difference of survivorship between patients with and without mutant p53 expression. These results suggest that immunohistochemical analysis of bladder cancer specimens could be a good method of screening for the presence of mutant p53 protein, and mutant p53 protein expression may be an indicator of bladder cancer with more proliferative and/or aggressive activity, but it may not be an clinically useful prognostic factor in patients with bladder TCC.

Urethral stricture usually follows the urethral rupture and periodical urethral soundation, which is an annoying procedure for. patients, is the usual method of treatment throughout their life. A case of urethral stricture who was successfully treated with modified Cecil's Operation, is presented.

The effect of Roentgen rays on carcinoma of the cervix has long been of great interest to both radiologists and gynecologists. Since most cervical carcinomas are treated by irradiation, any additional knowledge either concerning the radiosensitivity of cervical tumors or their ultimate prognosis would be of value. The vaginal smear is considered to be one of convenient and rapid methods to study the effects of radiation on cervical malignancy. We observed morphologic changes in 297 cytologic preparations obtained from 60 patients who had underwent irradiation for cancer of the cervix. With the morphologic parameters such as cytoplasmic vacuolization, cytoplasmic basophilia, multinucleated giant cell formation, polymorphonuclear leucocytes (PMNL) sticking and postradiation dysplasia, we analyzed the findings in relation to the follow up time interval. The most common effect was the cytoplasmic vacuolization with basophilia of basaloid cells, which were noted in more than 90% of followed patients. The multinucleated giant cell formation and PMNL stickering were noted in 38 cases(63%) and 48 cases(80% ) respectively. The differential diagnosis of postradiation dysplasia from recurrent or persistent carcinoma, reparative atypical cells, and regressing tumor cells was difficult and further study seems to be needed to clarify the more accurate morphologic features and biologic behavior.

Erythr odysesthesia syndrome is a. peculiar toxic reaction due to anti-cancer drug. lt is characterized by a painful, purple-colored patch on the palms and soles, and may form bullae. We report a case of erythrodysesthesia syndrome in a 46-year-old woman. 5-FU and leucovorin were administered for 5 days because of her colon cancer. Two weeks after anti-cancer therapy, purple-colored erosive patch appeared on the face, and 10 days later, purple-colored vesicular patches were seen on both palms and soles, accompanied with pain. Histopathologic examination reveals a severe epidermal necrosis. Individual keratinocyte shows cytologic atypia and apoptotic body.

The present study evaluates the type, frequency and location of basal cell epithelioma, as well as the age and sex distribution of patients and the recurrence rate of basal cell epithelioma. In this study 116 patients, who visited Severance hospital during the last 15 years from Jan. 1, 1967 to Dec. 31, 1981 and were diagnosed histopathologically as having basal cell epithelioma, were analysed.

Keratoacanthoma is a benign neoplasm that develops as a protruding mass especially on the central part of face, We experienced a case of keratoacanthoma that developed on the nasal vestibule after the eradication of verruca vulgaris on the same site by surgical intervention 3 months before. We treated it with total excision and skin graft.

9.Prognostic parameters in Renal Cell Carcinoma.
Korean Journal of Urology 1988;29(3):375-380
This Study was designed to characterize the unfavorable prognostic factors of renal cell carcinoma through reviewing 27 cases with radical nephrectomy during the past 10 years from 1976 through 1986. The presence or absence of tumor invasion into renal capsule, perinephric fat, renal vein, regional lymph node, pelvis and/or ureter, hematuria at the time of first examination and the difference in the size of tumor and tumor cell type were studied. The 100 person-year mortality rates were analyzed with the chosen prognostic variables. Tests of significance between the difference in mortality rates of each two groups with or without a given characteristics were performed with Z-test. Author results as follows. : 1. The survival rate was decreased independently by the unfavorable factors such as the presence of tumor invasion into renal vein, regional lymph node, pelvis and/or ureter and tumor cell type other than clear cell(P<0.001, <0.001, <0.001, <0.05 respectively). 2. The survival rate was not affected by the following factors such as the presence or absence of hematuria at the time of first examination, tumor invasion into renal capsule, perinephric fat and the difference in size of tumor.
