Alpha-Type 1 Polarized Dendritic Cells Loaded with Apoptotic Allogeneic Breast Cancer Cells Can Induce Potent Cytotoxic T Lymphocytes against Breast Cancer / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: Various tumor antigens can be loaded onto dendritic cells (DCs) to induce a potent cytotoxic T lymphocyte (CTL) response in DC-based immunotherapy against breast cancer. However, in the clinical setting, obtaining a sufficient number of autologous tumor cells as a source of tumor antigens is a laborious process. We therefore investigated the feasibility of immunotherapy using breast-cancer-specific CTLs generated in vitro by use of alpha-type 1 polarized DCs (alpha DC1s) loaded with ultraviolet B-irradiated cells of the breast cancer cell line MCF-7. MATERIALS AND METHODS: alphaDC1s were induced by loading allogeneic tumor antigen generated from the MCF-7 UVB-irradiated breast cancer cell line. Antigen-pulsed alphaDC1s were evaluated by morphological and functional assays, and the breast-cancer-specific CTL response was analyzed by cytotoxic assay. RESULTS: The alphaDC1s significantly increased the expression of several molecules related to DC maturation without differences according to whether the alphaDC1s were loaded with tumor antigens. The alphaDC1s showed a high production of interleukin-12 both during maturation and after subsequent stimulation with CD40L, which was not significantly affected by loading with tumor antigens. Breast-cancer-specific CTLs against autologous breast cancer cells were successfully induced by alphaDC1s loaded with apoptotic MCF-7 cells. CONCLUSION: Autologous DCs loaded with an allogeneic breast cancer cell line can generate potent breast-cancer-specific CTL responses. This may be a practical method for cellular immunotherapy in patients with breast cancer.

Adenomyoma of the common bile duct / 한국간담췌외과학회지

A fifty year old Korean female was admitted with a few months history of general malaise. On admission, positive HBs Ag, negative HBs Ab and HBe Ag was negative. The liver function tests showed AST 274 U/L, ALT 126 U/L, CEA 1.87 ng/ml. With the clinical impression of chronic hepatitis B, abdominal CT and ERCP were performed and demonstrated a narrowing of the distal common bile duct suggesting a malignant etiology. The Whipple's procedure was done. The intraoperative finding revealed neoplastic involvement of the distal 1 cm of the common bile duct with severe narrowing and proximal dilatation. Microscopic findings demonstrated cystically dilated ductular structures and intervening irregular hypertrophic smooth muscle bundles.

Pattern of Recurrence after Curative Resection of Gastric Cancer / 대한암학회지

PURPOSE: Despite radical lymph node dissection and combined resection, the operative result of progressive gastric cancer remains unsatisfactory. The prognosis of gastric cancer has not been improved. In case of recurred gastric cancer, the problem is low curative resection rate. We tried to study the pattem of recurrence after curative resection for gastric cancer. MATERIALS AND METHODS: We had retrospectively analyzed the recurrence pattern of 191 patients who recurred after curative resection of gastric cancer. We analyzed the interval between operation and recurrence, primary tumor location, tumor histologic type, Borrmann's type, pathologic stage, DNA ploidy pattem and lymph node metastasis. RESULT: The number of recurred gastric cancer patients was 191. The M: F ratio was 2.03: 1. Seven cases were early gastric cancer. The interval between operation and recurrence was from 1 month to 130 months. The early recurrence within 24 months was found in 147 patients (77.0%), the intermediate recurrence from 25 months to 60 months was found in 38 patients (19.9%), the late reeurrence after 60 months was found in 6 patients (3.1%). The pattems of recurrence were as follows: loco-regional recurience, including lymph node and site of anastomosis, was found in 51 cases, liver metastasis in 37 cases, peritoneal metastasis in 74 cases, extraperitoneal metastasis in 29 cases including Virchows node. In undifferentiated cancer, peritoneal metastasis was higher than in other histologic types (p<0.05). 59 cases was found in stage IV, 47 cases in stage IIIb, 43 cases in stage IIIa, 31 cases in stage II, 8 cases in stage Ib, and 3 cases in stage Ia. We found peritoneal metastasis was very high in stage IIIb. The 5-year survival was better in loco-regional group than that of other patterns of recurrence. CONCLUSION: Recurrence after operation was found within 24 months, that in most of patients, so the follow up is very important in this period and the recurred pattem after curative resection for gastric cancer was related with cell differentiation of primary tumor and stage. In local recurrence, the survival rate was higher than the other pattern of recurrence.

A comparative study on dental arch dimension of high school females according to the region of residence and facial type / 대한치과교정학회지

This study was performed to compare the dental arch dimensions of urban and rural high school females according to the region of residence and facial type. A model and cephalometric analysis was made from 48 urban and 48 rural high school females. The results of this study were obtained as follows: 1. Arch width in the urban group were similar to the rural group. 2. Lingual arch length at upper 1st premolar level in the urban group was larger than the rural group and lingual arch length at lower canine level in rural group was larger than the urban group. 3. Palatal height at canine level in the rural group was higher than the urban group. 4. Palatal heights at 2nd premolar and 1st molar level had correlation with the VERT index. In comparison of lingual arch dimensions according to Rickett's facial group, palatal heights at 2nd premolar and 1st molar level in dolichofacial group were lower than other groups.
