Background: The limitations of total serum PSA values remain problematic, especially after an initial negative prostate biopsy. In this prospective study of Chilean men with a continued suspicion of prostate cancer due to a persistently elevated total serum PSA, abnormal digital rectal examination and initial negative prostate biopsy were compared with the use of the on-line Chun nomagram, detection of primary malignant circulating prostate cells (CPCs) and free percent PSA to predict a positive second prostate biopsy. We hypothesized that men negative for circulating prostate cells have a small risk of clinically significant prostate cancer and thus may be conservatively observed. Men positive for circulating prostate cells should undergo biopsy to confirm prostate cancer. Materials and Methods: Consecutive men with a continued suspicion of prostate cancer underwent 12 core TRUS prostate biopsy; age, total serum PSA and percentage free PSA and Chun nomagram scores were registered. Immediately before biopsy an 8ml blood simple was taken to detect primary mCPCs. Mononuclear cells were obtained by differential gel centrifugation and identified using double immunostaining with anti-PSA and anti-P504S. Biopsies were classifed as cancer/no-cancer, mCPC detecton test as negative/positive and the total number of cells/8ml registered. Areas under the curve (AUC) for percentage free PSA, Chun score and CPCs were calculated and compared. Diagnostic yields were calculated with reference to the number of possible biopsies that could be avoided and the number of clinically significant cancers that would be missed. Results: A total of 164 men underwent a second biopsy; 41 (25%) had cancer; the AUCs were 0.65 for free PSA, 0.76 for the Chun score and 0.87 for CPC detection, the last having a significantly superior prediction value (p=0.01). Using cut off values of free PSA <10%, Chun score >50% and ${\geq}1$ CPC detected, CPC detection had a higher diagnostic yield. Some 4/41 cancers complied with the criteria for active surveillance, free PSA and the Chun score missed a higher number of significant cancers when compared with CPC detection. Conclusions: Primary CPC detection outperformed the use of free PSA and the Chun nomagram in predicting clinically significant prostate cancer at repeat prostate biopsy.

Background: Sequential use of circulating prostate cell (CPC) detection has been reported to potentially decrease the number of unnecessary prostate biopsies in men suspected of prostate cancer. In order to determine the real world effectiveness of the test, we present a prospective study of men referred to two hospitals from primary care physicians, one using CPC detection to determine the necessity of prostate biopsy the other not doing so. Materials and Methods: Men with a suspicion of prostate cancer because of elevated PSA >4.0ng/ml or abnormal DRE were referred to Hospitals A or B. In Hospital A all underwent 12 core TRUS biopsy, in Hospital B only men CPC (+), with mononuclear cells obtained by differential gel centrifugation identified using double immunomarking with anti-PSA and anti-P504S, were recommended to undergo TRUS biopsy. Biopsies were classifed as cancer or no-cancer. Diagnostic yields were calculated, including the number of posible biopsies that could be avoided and the number of clinically significant cancers that would be missed. Results: Totals of 649 men attended Hospital A, and 552 men attended Hospital B; there were no significant differences in age or serum PSA levels. In Hospital A, 228 (35.1%) men had prostate cancer detected, CPC detection had a sensitivity of 80.7%, a specificity of 88.6%, and a negative predictive value of 89.5%. Some 39/44 men CPC negative with a positive biopsy had low grade small volume tumors. In Hospital B, 316 (57.2%) underwent biopsy. There were no significant differences between populations in terms of CPC and biopsy results. The reduction in the number of biopsies was 40%. Conclusions: The use of sequential CPC testing in the real world gives a clear decision structure for patient management and can reduce the number of biopsies considerably.

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

This report is aimed to investigate the effect of Integrative Medicine Therapy (IMT) in treating metastasized ovary and endometrial cancer. A 51-year-old woman who was diagnosed double primary ovarian and endometrial cancer in 2009. The patient was treated with Laparoscopic Assisted Vaginal Hysterectomy (LAVH), Bilateral Salpingo Oophorectomy (BSO) Pelvic Lymph Node Dissection (PLND), adjuvant chemotherapy till Sep. in 2013. But metastases to Rt. External Iliac artery, Aortocaval area Lymph Nodes, Liver(caudate lobe), Rt. Buttock subcutaneous area, Lt. Gastric Area Lymph Nodes were found. Finally, the patient decided to be treated by IMT including Abnoba Viscum, Vitamin C, herbal medication and pharmacopuncture combined with chemotherapy. The efficacy was evaluated with Positron Emission Tomography and Computed Tomography (PET-CT) and Abdomen Computed Tomography (CT). The metastatic tumor in liver was disappeared and Rt. external iliac artery, aortocaval area Lymph Nodes, Rt. buttock subcutaneous area were also decreased after 6 months treatment. These results suggest that IMT may have a potential role for metastatic cancer.

비장 변연부 림프종(Splenic marginal zone lymphoma)은 드문 종양이며, 주로 노년층에서 발견되며, 절반 이상이 10년 이상 생존할 만큼 양호한 경과를 보인다. 본원에서는 이전에 보고된 바가 없는 비장 변연부 림프종과 조기위암이 동시에 발견된 환자의 수술적 치료를 경험하였기에 보고하는 바이다. 74 세 남자환자로 5년 전 알코올성 간경화를 진단 받은 이후 추적관찰 중 시행한 위내시경 검사에서 유문부에 조기위암이 발견되었다. 복부 전산화 단층 촬영 결과, 경미한 간경화와 비장비대, 복강 내 림프절병증이 관찰되었고, 근치적 절제를 위해 위 아전절제술을 시행하였다. 수술 당시 경미한 간경화와 비장이 매우 커져 있는 것과 더불어 다수의 복부 림프절비대가 관찰되었다. 이후 조직 검사 결과에서 조기위암과 림프절에서 비장 변연부 B 세포 림프종으로 진단되었다. 환자는 회복 후 골수검사와 PET 검사 등을 시행하였으며, 조직검사와 같은 결과를 얻었다. 이후 환자는 항암치료 계획 중이다. 비장 변연부 림프종은 Schmid 등에 의해 처음 명명되었으며, 비호치킨성 림프종의 1~2%를 차지한다. 이는 진단 당시 평균 나이가 65세이고, 드문 질환이지만 완만한 경과로 긴 생존 기간을 가지므로 추가로 악성종양이 발생될 수 있다. 대부분 진단 당시 무증상이며, 심각한 혈구 감소증이 없거나, 중등도의 비장비대를 동반한 무증상의 환자는 경과를 관찰하는 것이 타당하다. 본 환자는, 조기 위암 수술 중 발견되어 비장 변연부 림프종으로 진단된 경우로, 동시에 발견된 경우는 보고된 바가 없다. 드물기는 하지만, 비장 변연부 림프종을 가진 환자의 주의 깊은 추적 관찰로 이차로 발생되는 악성 종양을 조기에 발견하는 것이 중요하다.

We report a patient with combined hepatocellular-cholangiocarcinoma confined in the common hepatic duct and scirrhous type of hepatocellular carcinoma in the caudate lobe of liver simultaneously. The patient was a 55-yearsold Korean man with hepatitis B virus (HBV) carrier who was referred from a local hospital due to detected liver mass on abdominal computed tomography (CT). He has presented jaundice and weight loss for the previous 3 weeks. Laboratory examination showed AST/ALT elevation and hyperbilirubinemia. HBsAg was positive. The tumor marker study showed elevated AFP and DCP, not CEA and CA 19-9. Abdominal CT disclosed an about 2.1×0.9 cm sized soft tissue density in hilum with both intrahepatic duct (IHD) dilatations and an about 3×2.1 cm sized arterial enhancing lesion at segment 8 of the liver. Patient received 15 cycles of Gemcitabine/Cisplantin chemotherapy from February 27, 2013 to December 31, 2013. Caudate lobectomy of liver, segmental resection of bile duct and Roux-en-Y hepaticojejunostomy was performed on February 10, 2014. The final pathologic report showed double primary liver cancer, combined hepatocellular-cholangiocarcinoma in common hepatic bile duct and scirrhous type of hepatocellular carcinoma in segment 1 of the liver. This is a very unusual case in which combined hepatocellular-cholangiocarcinoma confined in the large bile duct and two rare hepatic cancers coexisted.

Background: Breast cancer is the most common female malignancy in the world. Beta glucan can be a hematopoietic and an immune modulator agent in cancer patients. The aim of this trial was to determine the effect of beta glucan on white blood cell counts and serum levels of IL-4 and IL-12 in women with breast cancer undergoing chemotherapy. Materials and Methods: This randomized double-blind placebo-controlled clinical trial was conducted on 30 women with breast carcinoma aged 28-65 years. The eligible participants were randomly assigned to intervention (n=15) or placebo (n=15) groups using a block randomization procedure with matching based on age, course of chemotherapy and menopause status. Patients in the intervention group received two 10-mg capsules of soluble 1-3, 1-6, D-beta glucan daily and the control group receiving placebo during 21 days, the interval between two courses of chemotherapy. White blood cells, neuthrophil, lymphocyte and monocyte counts as well as serum levels of IL-4 and IL-12 were measured at baseline and at the end of the study as primary outcomes of the study. Results: In both groups white blood cell counts decreased after 21 days of the intervention, however in the beta glucan group, WBC was less decreased non significantly than the placebo group. At the end of the study, the change in the serum level of IL-4 in the beta glucan group in comparison with the placebo group was statistically significant (p=0.001). The serum level of IL-12 in the beta glucan group statistically increased (p=0.03) and comparison between two groups at the end of the study was significant after adjusting for baseline values and covariates (p=0.007). Conclusions: The findings suggest that beta glucan can be useful as a complementary or adjuvant therapy and immunomodulary agent in breast cancer patients in combination with cancer therapies, but further studies are needed for confirmation.

The mouse double minute 2 (MDM2) gene plays a key role in the p53 pathway, and the SNP 309T/G single-nucleotide polymorphism in the promoter region of MDM2 has been shown to be associated with increased risk of cancer. However, no consistent results were found concerning the relationships between the polymorphism and prostate cancer risk. This meta-analysis, covering 4 independent case-control studies, was conducted to better understand the association between MDM2-SNP T309G and prostate cancer risk focusing on overall and subgroup aspects. The analysis revealed, no matter what kind of genetic model was used, no significant association between MDM2-SNP T309G and prostate cancer risk in overall analysis (GT/TT: OR = 0.84, 95%CI = 0.60-1.19; GG/TT: OR = 0.69, 95%CI = 0.43-1.11; dominant model: OR = 0.81, 95%CI= 0.58-1.13; recessive model: OR = 1.23, 95%CI = 0.95-1.59). In subgroup analysis, the polymorphism seemed more likely to be a protective factor in Europeans (GG/TT: OR = 0.52, 95%CI = 0.31-0.87; recessive model: OR = 0.58, 95%CI = 0.36-0.95) than in Asian populations, and a protective effect of the polymorphism was also seen in hospital-based studies in all models (GT/TT: OR = 0.74, 95%CI = 0.57-0.97; GG/TT: OR = 0.55, 95%CI = 0.38-0.79; dominant model: OR = 0.69, 95%CI = 0.54-0.89; recessive model: OR = 0.70, 95%CI = 0.51-0.97). However, more primary studies with a larger number of samples are required to confirm our findings.
