Adenomatous Polyposis Coli*

This study was designed to evaluate the worth of preoperative chemoradiation therapy in the management of locally advanced rectal cancer. Between march 1993 and January 1997, 64 patients with adenocarcinoma of the rectum were treated with preoperative irradiation followed by operation by one surgeon at department of surgery, Chungnam national university hospital. Cancers were treated with high-dose radiation (45 to 54 Gy) with (group 2) or without (group 1) chemotherapy Preoperatively 64 Patients were analysed prospectively, of these, 15 cases were preoperative radiotherapy alone arm and 49 cases were preoperative radiotherapy plus chemotherapy arm. The average age of the patients were 56 years (range 38~67) in group 1 and 57 years (range 27~80) in group 2. Male to female ratio was 8 : 7 in group 1 and 30 : 19 in group 2. Most clinical stage of the primary tumor mass were 73 (80% in Group 1,96% in group 2), being palpated slightly fixed (40% in group 1, 43% in group 2) or fixed (13.3% in group 1, 24.5% in group 2). As to distance of tumor from anal verge, most patients ranged from 4 to 8 cm (53% in group 1, 63.3% in Group 2). Chemotherapy consisted of 2 cycles of 5-fluorouracil (500 mg/m2/day for S days) delivered as a continuous infusion or bolus therapy and low-dose leukovorin (20 mg/m2/day for 5 days). After six weeks resting period of radiation, definitive surgical approach was performed. Overall treatment related toxicity rate was similar in both group except erythema on perineal skin, which was more frequent in group 2 than in group 1. Most frequent postoperative complication was intestinal obstruction (7.8%) followed by wound infection (6.3%), but there was no significant difference between two groups. There was one case of postoperative mortality in group 2 patients at 44 days after operation due to pneumonia and sepsis combined with liver cirrhosis. Tumor depth was downstaged in 38.5% of group 1 and 70% of group 2 patients on preoperative CT staging, and nodal downstaging was more effective on the respect of postoperative pathological report. Overall recurrence rate was 38.5% in group 1 and 20.5% in group 2. Of these, failure occured first as a distant metastasis more frequently than as a local recurrence in both group. These data do suggest that the preoperative chemotherapy and radiotherapy used are as safe as preoperative radiotherapy alone. Futhermore, tumor and lymph node downstaging are more effective in combined arm. Preoperative chemotherapy will more promising in prevention of distant metastasis when treated in the period of least metastatic tumor burden. Whether combined arm will have greater or lesser survival awaits the completion of this relevant study.

A fine needle aspiration biopsy specimen of a retroperitoneal mass in a 26-year-old man who had had an orchiectomy for seminoma was submitted for cytologic evaluation. Cytologic features of the specimen included uniform neoplastic cells found singly or in groups of several cells intermingled with lymphocytes in a characteristic foamy, lacelike background. These cells varied from 10 to 20 m in diameter. The nuclei were round to ovoid with fine or reticular chromatin and one or more prominent nucleoli. The poorly defined cytoplasm stained pale-blue or blue with cytoplasmic vacuoles. The cytologic appearance was consistent with seminoma. Documented reports of the cytological appearance of seminoma are rare. The diagnosis of primary gonadal seminoma by fine needle aspiration biopsy is probably not indicated since the treatment of a primary gonadal tumor, regardless of its histogenesis, requires surgical resection. However, fine needle aspiration biopsy is extremely valuable in the diagnosis of extragonadal as well as metastic and recurrent seminoma.

BACKGROUND/AIMS: Filicide, the murder of a child by his or her own parent, is a multifaceted phenomenon with diverse causes and characteristics. This study aimed to review the present state of knowledge regarding demographic, psychosocial, clinical, and legal characteristics of filicide. METHODS: Domestic and International database were systematically searched with keyword of "filicide" for studies published until October, 2010, in English or Korean. Of the 107 searched articles, those that were overlapped in contents or out of the scope of this review were excluded. Finally, total 88 literatures were included in this review. RESULTS: The characteristics of the parents who committed filicide varied greatly by the type of the sample enrolled in studies. The results of the review suggested that little is known about the factors that confer victimization risk to children. The legal punishment was also different by nations. CONCLUSION: Given the range of capability of filicide, mental health professionals should be alert to the possibility of filicide in a variety of parents. A systematic and more focused research to elucidate reliable predictors of filicide is needed to better prevent these tragic events.

We have reviewed malignant lymphomas in children (15 years and less) that were diagnosed at the Department of Pathology, Seoul National University Hospital and Seoul National University Children's Hospital over the last 10 years, 1979~1989, trying to find any significant histological difference between childhood and adult lymphomas. After critical review by 3 pathologists, the lymphomas are classified according to Rappaport, Lukes-Collins and NCI (working formulation) classifications for non-Hodgkin's lymphomas and Reye classification for Hodgkin's disease. Fifty mine non-Hodgkin's lymphoma (NHL) and 18 Hodgkin's disease (HD) was the material that this study was based. NHL vs HD was 3 : 1, this HD being 23.4% of all malignant lymphomas in children.

C-erbB-2 oncoprotein has been known to act as growth factor receptor responsible for the regulation of cellular growth, proliferation and differentiation and has been demonstrated in a number of cancers by immunohistochemical as well as matrix blotting techniques. Breast and ovarian cancer patients, whose tumor cells have amplification or overexpression of this oncoprotein, have been suggested to have worse prognosis. Yet, there are only a few studies on c-erbB-2 oncoprotein expression in transitional cell carcinoma(TCC) of the bladder. The aim of this study was to examine c-erbB-2 oncoprotein expression in bladder cancer to assess its potential as a useful prognostic marker in transitional cell carcinoma of the bladder. Deparaffinized tumor specimens from 42 patients with TCC of the bladder and 3 normal bladder tissue specimens were utilized. C-erbB-2 oncoprotein expression was detected by immunohistochemical analysis and then correlated with conventional prognostic variables such as histologic tumor grade, stage and DNA ploidy. In addition, we related the expression of c-erbB-2 oncoprotein to indicators of cellular proliferative activities such as proliferating cell nuclear antigen(PCNA), mean number of silver nucleolar organizer regions(AgNORs) per nucleus, flow cytometric S-phase fraction(CPF) and proliferation index(PI). The incidence of c-erbB-2 oncoprotein expression in Ash grade IV TCC of bladder was higher than that in Ash grade II and III (Chi-square test, p<0.05). The incidence of positive immunoreaction was higher in cases with muscle invasion and metastasis than in superficial tumors with statistical significance(p<0.05). In addition, statistical significant correlation was noted between c-erbB-2 oncoprotein expression and PCNA expression rate. But there were no significant differences in c-erbB-2 oncoprotein expression to DNA ploidy, PI nor SPF by flow cytometry and mean number of AgNORs per nucleus. The results of this study suggests that the c-erbB-2 oncoprotein together with other predictive parameters may serve to provide a phenotypic profile which permits more accurate forecasting of bladder cancer behavior and may prove to be useful in the future as an important guide to specific anti-tumor therapy.
