Excess dietary fat intake is associated with many chronic diseases. This crosssectional
study determines the differences in nutritional status and diet-related psychosocial factors by accuracy levels of dietary fat intake perceptions among
adults. A total of 202 Universiti Putra Malaysia staff (20-55 years old) volunteered
to participate in the study. Dietary fat accuracy levels (under-estimate, accurate
and over-estimate) were determined by assessing actual fat intake through 24-hour diet recall and self-rated fat intake. Diet-related psychosocial factors assessed
were perceived risks, intention to change, outcome expectancies and perceived
barriers. About half (49.5%) of the respondents were classified as accurate
estimators, while 35.6% and 14.9% were under-estimators and over-estimators,
respectively. Dietary fat intake differed significantly between the dietary fat accuracy groups with under-estimators having the highest amount of dietary fat
intake (F=17.10; p<0.001) and percentage of fat calories (F=103.99 + 0.533%, p<0.001). Over-estimators had the highest mean BMI (F=3.11, p<0.05) compared
to other groups. Among the fat accuracy groups, under-estimators reported the
least barriers to eating low fat foods (F= 3.671, p<0.05). There were no significant
differences in waist circumference, energy intake, perceived disease risks,
intention to change and outcome expectancies among the dietary fat accuracy
groups. These findings suggest that inaccurate perceptions of dietary fat intake
should not be overlooked as one of the cognitive barriers to dietary change and
factors that influence nutritional status among adults.

A case of postirradiation extraskeletal osteosarcoma with aggressive fibromatosis of the overlying soft tissue of radiation field is reported in a 57 year old house wife who was treated with operation and radiation therapy for cervix carcinoma of the uterus 23 years ago. The overlying aggressive fibromatosis showed characteristic radiation angiitis and atrophic vascular changes such as hyaline degeneration and obliteration of the capillaries which were highly campatible with radiation changes. She also had multiple osteogenic sarcoma in pelvic cavity, occurring in the mesentery bed. As for the histogenesis in this case, we thought the possiblity that fibroblasts went through a process of differentiation into osteoblasts that were responsible for bone formation in the process of malignant change of the aggressive fibromatosis.

PURPOSE: The status of the axillary nodes in breast carcinoma patients is one of the most significant prognostic factors. Although many trials in order to gain information concerning axillary status, to date there is no satisfactory procedures other than axillary lymph node dissection (ALND) which has many complications. Recently sentinel lymphadenectomy has become accepted as an alternative to ALND. METHODS: Sentinel lymphadenectomy followed by ALND was performed in 157 patients with invasive breast carcinoma between Nov. 1998 and Dec. 2000. The period from Nov. 1998 to May. 1999, which included the first 54 patients was set as a learning period. 99m Tc antimony trisulfide colloid was used in the detection of the sentinel node, with a gamma camera preoperatively and then a gamma probe in the operating room. The dissected sentinel nodes were examined by both frozen section and serial section (SS) with immunohistochemical stains (IHC). RESULTS: The detection rate was 96.8%. The false negative rate was 22.6% for the frozen sections and 4.8% for the permanent sections. The detection rate and the false negative rate had improved after the learning period with statistic significance (P-value<0.05). The false negative rate for tumors less than 2 cm was significantly lower than that for tumors greater than 2 cm (P-value=0.000). CONCLUSION: Sentinel lymphadenectomy using 99m Tc anti-nomy trisulfide colloid showed high detection rate and low false negative rate. The learning period is thought to be necessary for its clinical application. In the future, sentinel lymphadenectomy may replace axillary lymph node dissection in certain subgroups of breast carcinoma patients.

PURPOSE: Although an axillary lymph node dissection (ALND) has been considered as an ultimate procedure for axilla in the breast carcinoma, complications after ALND and conceptual revolution for the role of axillary nodes have made it necessary to look for an alternative. Recent studies of sentinel lymphadenectomy (SLND) have shown that SLND accurately predict axillary nodal status. However, for a satisfying outcome in SLND, a learning period would be required, as other surgical procedures do. In this study, the necessity of the learning period for SLND were examined. METHODS: From Nov. 1998 to Dec. 2001, 178 patients with invasive breast carcinoma were treated with SLND simultaneously followed by ALND. The period for the first 54 patients, Nov. 1998 to May. 1999, was set as a 'learning period'. Differences of the detection rate and the false negative rate for the 'learning period' and 'after the learning period' were compared. Also changes in the detection rate and the false negative rate with the accumulated experiences for SLND were evaluated. RESULTS: The sentinel lymph nodes were not identified in 5 patients through the whole period. Three of them occurred in the 'learning period' (5.6%, 3/54) and the rest occurred 'after the learning period' (1.6%, 2/124)(P=0.04). The false negative rate was 16.7% (4/24) in the 'learning period' and 0.0% in 'after the learning period' (P=0.00). The detection rate and the false negative rate improved with the accumulation of experiences for SLND. CONCLUSION: It is certain that 'learning period' for SLND is crucial. During this period, the improvement and stabilization of this skill is achieved.

The learning period is thought to be necessary for its clinical application. In the future, sentinel lymphadenectomy may replace axillary lymph node dissection in certain subgroups of breast carcinoma patients.

PURPOSE: To assess the appropriateness of radiotherapy volume for patients receiving breast-conserving treatment (BCT) through analysis of recurrence pattern and factors affecting recurrence. METHODS: From 1991 to 1996, 362 patients who received BCT were retrospectively evaluated. The radiation volume was the involved breast alone in the patients with less than 4 positive axillary lymph nodes (LNs), and breast and supraclavicular fossa in patients with 4 or more positive axillary LNs. The median follow-up period was 123 months (range, 3-169 months). RESULTS: Ten-year overall, disease-free, local recurrence-free, and regional recurrence-free survival rates were 86.2%, 82.2%, 95.9%, and 95.2%, respectively. Among 310 patients receiving radiotherapy on the breast alone, 15 (4.8%) had regional recurrence. In particular, patients with inner quadrant lesions had high regional recurrence rates (11/98, 11.2%) (p<0.001). CONCLUSION: These low local recurrence rates may reveal that the current radiotherapy technique was successful. However, in cases of inner quadrant lesions, there were a considerable number of regional recurrences, even in N0 cases. This may suggest a potential role for irradiation on regional LNs in this group.

Clinical application of the cartilage formed by tissue engineering is of no practical use due to the failure of long-term structural integrity maintenance. One of the important factors for integrity maintenance is the biomaterial for a scaffold. The purpose of this study is to evaluate the difference between polylactic-co-glycolic acids (PLGA) and chitosan as scaffolds. Human auricular chondrocytes were isolated, cultured, and seeded on the scaffolds, which were implanted in the back of nude mice. Eight animals were sacrificed at 4, 8, 12, 16, and 24 weeks after implantation respectively. In gross examination and histological findings, the volume of chondrocyte-PLGA complexes was decreased rapidly. The volume of chondrocyte-chitosan complexes was well maintained with a slow decrease rate. The expression of type II collagen protein detected by immunohistochemistry and western blots became weaker with time in the chondrocyte-PLGA complexes. However, the expression in the chondrocyte-chitosan complexes was strong for the whole period. Collagen type II gene expressions using RT-PCR showed a similar pattern. In conclusion, these results suggest that chitosan is a superior scaffold in cartilage tissue engineering in terms of structural integrity maintenance. It is expected that chitosan scaffold may become one of the most useful scaffolds for cartilage tissue engineering.

PURPOSE: The need for completion axillary lymph node dissection, even in early breast cancer patients with a positive sentinel lymph node, has been questioned. The purpose of this study was to determine the factors that predict the presence of metastasis in non-sentinel lymph nodes (NSLNs) when the sentinel lymph node (SLN) was positive. METHODS: Between December 1998 and June 2004, the records of 104 early breast cancer patients with a positive SLN and who underwent completion axillary lymph node dissection were reviewed. The clinicopathological features in SLN-positive patients were evaluated as possible predictors of metastatic NSLN. RESULTS: Forty four (42.3%) of the 104 patients with positive SLN had metastatic NSLNs. In a univariate analysis, unicentric multifocality (P=0.016), lymphovascular invasion (P=0.006) and SLN metastasis larger than 2 mm (P= 0.003) were associated with positive NSLN findings. The number of SLNs removed was significantly associated as a negative predictor (P=0.043). A multivariate analysis revealed that SLN metastasis >2 mm (P=0.021) and lymphovascular invasion (P=0.040) were independent predictors of metastatic NSLN. CONCLUSION: The likelihood of metastatic NSLNs correlates with the size of the largest SLN metastasis and the presence of lymphovascular invasion of the primary tumor. Even though in early breast cancer with positive SLNs, incorporating these factors may help determining which patients would benefit from additional axillary lymph node dissection.

Four cases of primary transitional cell carcinoma (TCC) arising in the ovary (3 cases) and the parovarium (1 case) were collected for clinicopathologic analysis. The mean age was 46.2 years (range, 39-57 years). Two patients complained abdominal discomfort and vaginal discharge, respectively. Other 2 cases were incidentally found from routine check. Grossly, the tumors were solid and cystic (2 cases), solid (1 case) and surface papillary growth on capsule (1 case). Microscopically, the tumor showed almostly same to the histologic features of TCC of urinary bladder. Three cases were pure TCC, and one was mixed TCC and serous carcinoma. FIGO stage were 1 IIa, 2 IIc, and 1 IIIc. Treatment was surgery with adjuvant chemotherapy. Two patients are alive with no evidence of disease, and two have lung or brain metastasis.

Endobronchial metastasis from uterine cervix cancer defines a bronchoscopically visible nonpulmonary neoplasm metastatic to the bronchus and histologically identical to cervix cancer. Endobronchial metastasis of uterine cervix cancer is rare, therefore, it is difficult to diagnose without pulmonary symptoms or abnormal radiological findings. Moreover, endobronchial metastasis of a nonpulmonary neoplasm is difficult to differentiate from a primary pulmonary neoplasm. The incidence of endobronchial metastasis is increasing because of the regular use of fiberoptic bronchoscopy and the longer survival of cancer patients. This study describes our experience of two patients with pulmonary symptoms and abnormal radiologic findings during the follow up of uterine cervix cancer, who were diagnosed as having endobronchial metastasis from uterine cervix cancer, and includes a brief review of related articles.
