Purpose: Anastomotic leakage (AL) is associated with high morbidity and mortality, high reoperation rates, and increased hospital length of stay. Here we investigated the risk factors for AL after anterior resection for rectal cancer with a double stapling technique. Patients and Methods: Data for 460 patients who underwent primary anterior resection with a double stapling technique for rectal carcinoma at a single institution from 2003 to 2007 were prospectively collected. All patients experienced a total mesorectal excision (TME) operation. Clinical AL was defined as the presence of leakage signs and confirmed by diagnostic work-up according to ICD-9 codes 997.4, 567.22 (abdominopelvic abscess), and 569.81 (fistula of the intestine). Univariate and logistic regression analyses of 20 variables were undertaken to determine risk factors for AL. Survival was analysed using the Cox regression method. Results: AL was noted in 35 (7.6%) of 460 patients with rectal cancer. :Median age of the patients was 65 (50-74) and 161 (35%) were male. The diagnosis of AL was made between the 6th and 12th postoperative day (POD; mean 8th POD). After univariate and multivariate analysis, age (p=0.004), gender (p=0.007), tumor site (p<0.001), preoperative body mass index (EMI) (p<0.001), the reduction of TSGF on 5th POD less than 10U/ml (p=0.044) and the pH value of pelvic dranage less than or equal to 6.978 on 3rd POD (p<0.001) were selected as 6 independent risk factors for AL. It was shown that significant differences in survival of the patients were AL-related (p<0.001), high ASA score related (p=0.036), high-level EMI related (p=0.007) and advanced TNM stage related

Fourteen cases of pericardia I tumor were clinically experienced from June 1966 to July 1981, for 15 years in St. Mary's Hospital, Department of Thoracic and Cardiovascular Surgery, Catholic Medical College. There were three primary tumors of the pericardium, liposarcoma, teratoma and malignant mesothelioma, and 11 metastatic pericardial tumors. In metastatic pericardial tumors, eight were originated from the lung, one was breast, and the other two cases were unknown origin. There were 6 adenocarcinoma, one small cell carcionoma ~nd one alveolar cell carcinoma in 8 cases from the lung, and 5 male and 3 female patients were composed the metastatic pericardial cancer from the lung. In clinical symptoms were dyspnea in all cases, and 9 cases had the generalized edema and enlarged liver size. Six patients had been operated, three of the primary pericardial tumor and three of metastatic pericardial tumor. Two of the primary tumors were cured satisfactorily by the mass removal, but one died due to cardiac arrest at postoperative one day. In metastatic tumors, operation were performed as two pericardial window formation and one left lower lobectomy with pericardial fenestration, but one was died in second operative day. Other nine metastatic tumors were diagnosed by needle biopsy in one case and by cell block of effusion in eight cases.

Aim: Metastatic tumor of bone is the most common malignancy involving bone and is an important predictor of prognosis in advanced cancers. The prognosis depends upon the primary site of origin and the extent of disease. In current study, we present the pattern and distribution of metastatic bone disease seen in the leading cancer care center of Pakistan, Shaukat Khanum Cancer Hospital & Research Center (SKMCH & RC), Lahore. Materials & Methods: All cases of bony metastatic disease were included that presented in the Pathology Department, from Jan 2005 to July 2011. Patients of all ages and both sexes were included. Primary bone tumors, lymphomas, sarcomas and other malignancies were excluded. The data were recorded and analyzed with SPSS 16.0. Results: A total of 146 cases of metastatic bone disease were included in the study. Out of the total cases, 79 were male and 67 were female. Age range 25-82 years (median 52). Hip bone was the most frequent bone involved, with femur and vertebrae as second and third in the list. The commonest bone involved in males was vertebrae with 23 cases and in females was hip bone with 22 cases. Regarding primary site, cancers of breast, prostate and gastrointestinal tract were at the top of the list with prostate and breast being the most frequent primary sites of metastasis in males and females respectively. Conclusion: Bone metastasis is an important entity to consider in the differential diagnosis whenever a bony tumor especially carcinoma present in older age. Our data are comparable with international findings and the literature available regarding the site and distribution of skeletal metastatic lesions. A slight deviation noted was more common bony metastatic lesions with ovarian primaries in females and gastrointestinal tract cancers in males in our study.

Salivary duct carcinoma is an uncommon aggressive malignant epithelial neoplasm with similarity to intraductal carcinoma of the breast. This neoplasm occurs most often in the parotid gland of middle-aged and older males. About 7% of reported tumors occured in the submandibular gland. The report of salivary duct carcinoma with calcification is rare. We report a case of salivary duct carcinoma with calcification in the submandibular gland. The patient was a 73-year-old male with a mass of the right submandibular gland for 1 year. On the fine needle aspiration cytology, the aspirate showed scant cellularity, small clusters of tumor cells, and scattered small calcifications. Nuclei of the tumor cells showed mild pleomorphism and round to oval in shape, and cytoplasm was abundant and finely granular. Nucleoli were indistinct and necrosis was not noted. There were no cribriform or papillary arrangements of tumor cells. Cytologlc findings of salivary duct carcinoma are variable depending on histologic findings, and calcifications could be an additional cytologic findings.

Metastatic cancer is the most common tumor of the skeleton. The prevalence of pathologic fracture may increase as patient survival is prolonged by improved cancer therapy. With recent advances in orthopaedic procedure and medical management of terminal cancer patients, it is generally agreed that aggressive treatment should be undertaken for patient with pathologic fracture secondary to metastatic disease, and a team approach should be utilized. The authors have reviewed twenty cases of pathologic fracture of the long bone due to metastatic tumor treated in the Department of Orthopedic Surgery, Yonsei University College of Medicine, from April 1989 to April 1994 and the following results were obtained. 1. The mean age at surgery was 58.4 years (ranged from 24years to 86years) and among 20 cases, 10 cases were male and the others were female. 2. The most frequent site of pathologic fracture in long bone is femur(15 cases, 75%), and followed by humerus(4 cases, 20%), tibia(1 case). 3. The frequently encountered primary tumors that metastases to long bone are those of the lung(7 cases, 35%), breast(4 cases, 20%), and prostate(2 cases, 10%). 4. The operative procedure was performed by resection of the tumor mass extensively, and we used polymethylmetacrylate for filling the dead space after resection, in all cases. 5. The mean survival period after operation is 9.2 months(ranged from 1 month to 4 years and 9 month). 6. The results of postoperative pain relief status were graded as fair to excellent in 17 cases(85%).

Background: The DR-$70^{TM}$ immunoassay is a newly developed cancer diagnostic test which quantifies the serum fibrin degradation products (FDP), produced during fibrinolysis, by antibody reaction. The purpose of this study was to evaluate the potential of DR-$70^{TM}$ Immunoassay in screening malignant tumor. Methods: Sample subjects were 4,169 adults, both male and female, who visited the health promotion center of a general hospital from March 2004 to April 2005 and underwent the DR-$70^{TM}$ immunoassay test and other tests for cancer diagnosis. The patient group was defined as 42 adults out of the sample subjects who were newly diagnosed with cancer during the same time period when the DR-$70^{TM}$ immunoassay test was performed. Final confirmation of a malignant tumor was made by pathological analysis. Results: The mean DR-$70^{TM}$ level was $0.83{\pm}0.65{\mu}g/ml$ (range: 0.00 (0.0001)${\sim}7.42{\mu}g/ml)$ in the control group (n=4,127) as opposed to $2.70{\pm}2.33{\mu}g/ml$ (range: $0.12{\sim}9.30{\mu}g/ml)$ in the cancer group (n=42), and statistical significance was established (p<0.0001, Student t-test). When categorized by the type of malignant tumor, all cancer patients with the exception of the subgroups of colon and rectal cancer showed significantly higher mean DR-$70^{TM}$ levels compared with the control group (p<0.0001, Kruscal-Wallis test). The receiver operating characteristic (ROC) curve analysis revealed ${\geq}1.091{\mu}g/ml$ as the best cut-off value. Using this cut-off value, the DR-$70^{TM}$ immunoassay produced a sensitivity of 71.4%, a specificity of 70.1%, a positive predictability of 69.4%, and a negative predictability of 69.2% (1). Conclusion: A significant increase in the mean DR-$70^{TM}$ value was observed in the cancer group (thyroidal, gastric, breast, hepatic and ovarian) com pared with the control group. In particular, the specificity and sensitivity of the DR-$70^{TM}$ immunoassay was relatively high in the subgroups of breast, gastric, and thyroidal cancer patients. There is need for further studies on a large number of malignant tumor patients to see how the DR-$70^{TM}$ level might be changed according to the differentiation grade and postoperative prognosis of the malignant tumor.

The development of skin metastasis is usually a morbid prognostic feature although they occur infrequently. Adenocarcinomas account for up to about 70% of all metastatic skin cancer. In general, adenocarcinomas are the most difficult metastatic tumor to accurately identify the primary site because they don't have distinctive histological features. For this reason, immunohistochemistry have been used to help identify the origin of metastatic adenocarcinomas. This study performed immunohistochemical staining with metastatic adenocarcinomas of the skin using a variety of antisera to find out characteristic immunohistochemical findings of them. This study was made upon the 29 cases of metastatic adenocarcinomas of the skin, which had been confirmed histopathologically in Chonbuk National University Hospital from January, 1986 to April, 2006, Paraffin blocks were colledted and homemade tissue arrays were made. We performed immunohistochemical staning using 12 antibodies (MUC1, 2, 5AC, 6, cytokeratin (CK) 7, 20, thyroid transcription factor-1 (TTF-1), estrogen receptor (ER), progesterone receptor (PR), beta-catenin, cox-2, claudin-1). The mean age at the time of diagnosis was 60.7 years and the male to female ratio was 1.2:1.0. The most common primary site was lung, followed by stomach and colorectum. MUC1 was expressed by most colorectal, breast and lung adenocarcinoma. MUC2 was expressed infrequently. MUCSAC was expressed by most gastric and colorectal cancer MUC6 was not specific of any primary site in this series. CK7+/CK20+immunophenotype was observed in gastric, lung, colorectal adenocarcinoma. CK7+/CK20- immunophenotype was observed in breast, lung, endometrial, uterine cervical, bile duct adenocarcinoma, while CK7-/CK20+ immunophenotype was observed only in colorectal adenocarcinoma. This results show the utility of TTF-1 to confirm the pulmonary origin. On the other hand ER and PR were not useful markers to assess the origin of primary tumor in this series.

Objective : We investigated the outcomes of repeat stereotactic radiosurgery (SRS) for metastatic brain tumors that locally recurred despite previous SRS, focusing on the tumor control. Methods : A total of 114 patients with 176 locally recurring metastatic brain tumors underwent repeat SRS after previous SRS. The mean age was 59.4 years (range, 33 to 85), and there were 68 male and 46 female patients. The primary cancer types were non-small cell lung cancer (n=67), small cell lung cancer (n=12), gastrointestinal tract cancer (n=15), breast cancer (n=10), and others (n=10). The number of patients with a single recurring metastasis was 95 (79.8%), and another 19 had multiple recurrences. At the time of the repeat SRS, the mean volume of the locally recurring tumors was 5.94 mL (range, 0.42 to 29.94). We prescribed a mean margin dose of 17.04 Gy (range, 12 to 24) to the isodose line at the tumor border primarily using a 50% isodose line. Results : After the repeat SRS, we obtained clinical and magnetic resonance imaging follow-up data for 84 patients (73.7%) with a total of 108 tumors. The tumor control rate was 53.5% (58 of the 108), and the median and mean progression-free survival (PFS) periods were 246 and 383 days, respectively. The prognostic factors that were significantly related to better tumor control were prescription radiation dose of 16 Gy (p=0.000) and tumor volume less than both 4 mL (p=0.001) and 10 mL at the repeat SRS (p=0.008). The overall survival (OS) periods for all 114 patients after repeat SRS varied from 1 to 56 months, and median and mean OS periods were 229 and 404 days after the repeat SRS, respectively. The main cause of death was systemic problems including pulmonary dysfunction (n=58, 51%), and the identified direct or suspected brain-related death rate was around 20%. Conclusion : The tumor control following repeat SRS for locally recurring metastatic brain tumors after a previous SRS is relatively lower than that for primary SRS. However, both low tumor volume and high prescription radiation dose were significantly related to the tumor control following repeat SRS for these tumors after previous SRS, which is a general understanding of primary SRS for metastatic brain tumors.

Objective : This study was aimed to obtain epidemiological information of cancer patients treated with Oriental medicine. Methods :The medical records of 899 cancer patients treated at the East-West Cancer Center of Dunsan Oriental Hospital from January to December 2008 were analyzed. Careful investigations were done by categorizing these patients by their sex, origin, stage, treatment duration, conventional treatment type, etc. Results : 61.7% of the patients had stage IV tumor. 53.1% of patients visited Oriental hospital for combination treatment with conventional medicine. In the tumor origin, lung cancer showed the largest proportion (21.6%). Of the two genders, lung cancer was the most frequent cause (31%) in male patients, and breast cancer in females (21.2%). In inpatients, thyroid cancer resulted in the highest percentage (24.0%). Lung, colon, stomach cancer patients were mostly in stage III or IV. Thyroid cancer patients were mostly in stage I. Conclusions : This study presented the characteristics of cancer patients treated by Oriental medicine. Based on this study, further advanced study of Oriental medical cancer treatments is needed.
