Background: The prognostic significance of the neutrophil-to-lymphocyte ratio for progression free survival in patients with metastatic renal cell carcinoma is unclear. Materials and Methods: We retrospectively reviewed 45 patients diagnosed with metastatic RCC previously treated with tyrosine kinase inhibitors from two centers, Akdeniz University Hospital and Afyon Kocatepe University. The prognostic value of the pretreatment neutrophil-tolymphocyte ratio, and other clinical and laboratory parameters were assessed by univariate and multivariate analysis. Results: Median progression free survival (PFS) was 13.9 months [95% CI for HR (6.88-20.91)] and overall survival figure of 16.6 months [95% CI for HR (7.23-26.03)] Univariate analysis revealed that PFS was significantly affected by hemoglobin level [p=0.013 (95% CI for HR (0.71-0.96))], eosinophil count [p=0.031 (95% CI for HR (0.20-0.92))], ratio of neutrophil lymphocytes (NLR) [p=0.007 (95% CI for HR (1.47-11.74))] and calcium level [p=0.006 (95% CI for HR (0.15-0.73))]. However, only NLR [p=0.031 (95% CI for HR (1.15-18.1))] and calcium levels [p=0.018 (95% CI for HR (0.20-18.1))] retained significance with multivariate analysis. Median PFS was 23.9 vs 8.6 months in patients with NLR ${\leq}2$ vs NLR >2 (Log rank; p= 0.040). Conclusions: This study showed that increased pretreatment NLR is an independent prognostic factor for patients with metastatic RCC using tyrosine kinase inhibitors.

Background: Upper tract transitional cell carcinomas (UTCC) are relatively uncommon but prognosis is generally worse than TCC of bladder. Methods: Between March 2004 and June 2012, patients with initial non-metastatic UTCC were assessed in the Medical Oncology and Urology Departments of Ataturk Training and Research Hospital. Results: A total of 11 patients with initially non-metastatic UTCC were detected in the 8 year period, all males. Median age of was 62 (range, 38-74). Six lesions were located in the renal pelvis and 5 in the ureter. Nephroureterectomy was performed in 9 patients, and distal ureterectomy and cuff excision of the bladder in the remaining 2. The majority (n= 9) had high grade tumors. Median primary tumor diameter was 3.5 cm (range, 0.7-10). Five patients (45.5%) were stage I, 2 (18.2%) were stage II, and 4 (36.4%) were stage III. While adjuvant chemotherapy was not applied for stage I and II disease (n= 7), 4 to 6 courses were applied for 3 of the stage III patients. Also one stage III case received adjuvant radiotherapy. Up to 100 months follow-up, median overall survival was 13 months (range, 5-100 months). While stage I and II patients are following-up without muscle-invasive progression, 2 of stage III patients demonstrated progression. Conclusion: We need more collaborative studies to determine management of especially pT3-pT4 patients with UTCC.

The purpose of this study was to explore the effects of hand reflexology on the physiological.emotional responses and immunity of the patients with chronic illness. This study looked specifically at patients with chronic renal failure(CRF) and cancer patients. Method: This study was designed as a quasi-experimental nonequivalent control group pre and post test. Subjects were 54 patients who received dialysis and chemotherapy in one hospital. Thirty-one patients were assigned to the experimental group and 23 to the control group. The hand reflexology was applied to both hands of the experiment group for ten minutes each time, 5 times during three days. For data collection, physiological lab levels, immune cells of blood and questionnaires for emotional responses were measured before and after the program. Result: BT of the experiment group was decreased significantly on both of the 1st and the 5th application. PR & BP were decreased significantly on the 1st times, but not 5th times. Hb levels of the experimental group were significantly increased. And emotional responses, vigor and mood scores of the experiment group were significantly increased. B cell & CD19 were increased significantly on the experiment group. Suppressor T cell and NK cell showed significant decrease after the program, but no significant differences between the groups. Conclusion: We have found that the hand reflexology helps the chronic patients to improve physiological.emotional responses and the immune reaction. Through this result, the hand reflexology is effective as a intervention of psychoneuroimmunologic function.

Background: Although studies and interest in sarcopenia have increased, it is still a matter of debate which muscle mass index better represents the aging process. We compared 3 indices for muscle mass (appendicular skeletal muscle mass [ASM]/weight, $ASM/height^2$, and the body mass index [BMI]-adjusted muscle mass index [ASM/BMI]) to determine which better reflected the aging process in terms of the decline in bone mineral density (BMD), visual acuity (VA), hearing power, renal function, pulmonary function, and handgrip strength. Methods: We performed a retrospective cross-sectional study using the Korea National Health and Nutrition Examination Survey in the Korean population. Between 2008 and 2011, a total of 14,415 men and 17,971 women aged 10 years or older participated in the study. We plotted the changes in the 3 indices of muscle mass and compared these with changes in BMD, VA, hearing power, renal function, pulmonary function, and handgrip strength according to each age group. Results: The ASM/BMI showed similar changes in terms of surrogate markers of the aging process, while the ASM/weight and $ASM/height^2$ showed no correlation. Conclusions: Among muscle indices for sarcopenia, only the ASM/BMI represented the aging process.

비뇨기암에서의 $^{18}F-FDG$를 이용한 PET-CT 검사는 해부학적 구조 및 $^{18}F-FDG$의 배출 경로로 인해 암 진단에 한계가 있다. 그러한 한계점을 보완 할 수 있는 검사 중 아세트산을 이용한 검사가 진행되고 있으며 비뇨기암 환자를 대상으로 $^{11}C-Acetate$ PET-CT 검사의 임상 적용에 대하여 소개하고자 한다. 현재 본원에서 비뇨기암을 진단 받은 환자 중에 전립선암 환자 10명, 신세포암 환자 10명, 방광암 환자 2명을 총 22명을 임상 연구로 시행하였다. 모든 환자는 $^{18}F-FDG$ PET-CT 검사를 시행하였고, 평균 2주 정도의 기간 후에 $^{11}C-Acetate$ PET-CT 검사를 진행하였다. 검사 장비는 GE사의 D-710 PET-CT 장비를 사용했고, 검사 진행은 $^{11}C-Acetate$ 주사 후 15분 후에 PET-CT 검사를 시작하였고, $^{18}F-FDG$와 $^{11}C-Acetate$영상의 비교 평가는 핵의학과 전문의가 판별했다. 전립선암 환자의 경우 일반적으로 $^{18}F-FDG$의 섭취가 다른 암종에 비해 낮은 특징이 있다. 본원에서 연구된 10명의 환자 중 2명의 환자의 전이된 암이 $^{18}F-FDG$ 보다 $^{11}C-Acetate$의 섭취가 잘 나타났다. 신세포암의 경우 10명의 환자 중 8명의 환자에서 $^{18}F-FDG$ 보다 $^{11}C-Acetate$의 섭취가 확연히 잘 나타났다. 방광암 환자의 경우 방광의 $^{18}F-FDG$ 섭취가 너무 강하고, 이뇨제 사용여부와 환자의 조건이 맞지 않아 임상연구에서 제외하였다. 현재 임상 연구 진행 중인 검사로서 아직은 많은 환자에 대한 검사를 시행하지 못해서 이렇다 할 결과를 말하기에는 시기상조이다. 하지만, 해외에서는 이미 비뇨기암에서의 $^{11}C-Acetate$ PET-CT 검사가 어느 정도 유용하다는 논문이 많이 발표되었고, 본원에서도 현재 연구 진행 중이다. 보다 더 많은 환자에 대한 검사가 이루어진다면, 전립선암 환자에서 Prostatic specific antigen(PSA) 수치와 $^{11}C-Acetate$ PET-CT의 상관관계, 수술 전 환자에서의 조직 검사상의 Gleason sum 수치와의 상관관계, 다른 비뇨기암에서의 $^{18}F-FDG$ PET-CT 검사와 $^{11}C-Acetate$ PET-CT 검사 사이의 특이도, 민감도, 양성예측도, 음성예측도 등의 척도로서의 비교 등의 다양한 주제로서의 논문이 진행 될 수 있을 것이며, 비뇨기암에서의 $^{11}C-Acetate$ PET-CT 검사가 보다 더 활성화 되어 질 것이라 사료된다.

Individual differences in drug responses are associated with genetic and epigenetic variability of pharmacogene expression. We aimed to identify the relevant miRNAs which regulate pharmacogenes associated with drug responses. The miRNA and mRNA expression profiles derived from data for normal and solid tumor tissues in The Cancer Genome Atlas (TCGA) Research Network. Predicted miRNAs targeted to pharmacogenes were identified using publicly available databases. A total of 95 pharmacogenes were selected from cholangiocarcinoma and colon adenocarcinoma, as well as kidney renal clear cell, liver hepatocellular, and lung squamous cell carcinomas. Through the integration analyses of miRNA and mRNA, 35 miRNAs were found to negatively correlate with mRNA expression levels of 16 pharmacogenes in normal bile duct, liver, colon, and lung tissues (p<0.05). Additionally, 36 miRNAs were related to differential expression of 32 pharmacogene mRNAs in those normal and tumorigenic tissues (p<0.05). These results indicate that changes in expression levels of miRNAs targeted to pharmacogenes in normal and tumor tissues may play a role in determining individual variations in drug response.

Angiogenesis, the formation of blood vessels, is essential for preparing a closed circulatory system in the body, and for supplying oxygen and nutrition to tissues. Major diseases such as cancer, rheumatoid arthritis, and atherosclerosis include pathological angiogenesis in their malignant processes, suggesting anti-angiogenic therapy to be a new strategy for suppression of diseases. However, until the 1970s, the molecular basis of angiogenesis was largely unknown. In recent decades, extensive studies have revealed a variety of angiogenic factors and their receptors, including vascular endothelial growth factor (VEGF)-VEGFRs, Angiopoietin-Tie, Ephrin-EphRs and Delta-Notch to be the major regulators of angiogenesis in vertebrates. VEGF and its receptors play a central role in physiological as well as pathological angiogenesis, and functional inhibitors of VEGF and VEGFRs such as anti-VEGF neutralizing antibody and small molecules that block the tyrosine kinase activity of VEGFRs have recently been approved for use to treat patients with colorectal, lung, renal and liver cancers. These drugs have opened a novel field of cancer therapy, i.e. anti-angiogenesis therapy. However, as yet they cannot completely cure patients, and cancer cells could become resistant to these drugs. Thus, it is important to understand further the molecular mechanisms underlying not only VEGF-VEGFR signaling but also the VEGF-independent regulation of angiogenesis, and to learn how to improve anti-angiogenesis therapy.

Adiposity is a well-recognized risk factor of type 2 diabetes and cardiovascular disease, and recently there is increasing evidence that excess body weight is an avoidable cause of cancer, including gastrointestinal, endometrial, esophageal adenocarcinoma, colorectal, postmenopausal breast, prostate, and renal malignancies. The mechanisms whereby adiposity is associated with tumor development remains not well understood. There are some most studied hypothesized mechanisms such as, high levels of insulin and free levels of insulin-like growth factors, sex hormones, adipocytokines, and inflammatory cytokines, adiposity-induced hypoxia, and so on. The potential mechanisms and conclusions in adiposity associated with increased risk for developing malignancy, and the underlying cellular and molecular mechanisms will be studied very well in the near future.

From June 1987 to January 1991, 24 patients with moderate or massive pericardial effusion underwent subxiphoid pericardial window procedures for diagnosis and therapy. The patients` ages were ranged from 28 years to 71 years. The underlying diseases were chronic renal failure with long term hemodialysis in 3 cases, malignant lung cancer in 7 cases, stomach cancer in 2 cases, tuberculous pericarditis in 5 cases, pyogenic pericarditis in 2 cases, myxedema in one case, one metastatic squamous cell carcinoma from unknown origin and three of undefined etiology. Preoperative diagnoses of pericardial effusions were confirmed by echocardiogram in all cases. Subxiphoid pericardial drainages were performed under general[n=19] or local anesthesia[n=5]. Histological diagnoses were made from the inferior pericardial tissue in all cases except one. In this one case[tuberculous pericarditis], the subxiphoid pericardial approach was failed from intraoperative bleeding. There were two postoperative death, one[in malignant lung cancer] had postoperative ventricular tachycardia which result in cardiac arrest, and the other[unknown origin metastatic malignant effusion] had persistent tachyarrhythmia postoperatively and died on postoperative 5th days. Twenty three patients were followed up from 3 days to 9 months; mean follow-up day was 43 days. The preoperative and postoperative mean cardiothoracic ratio in chest x-ray were 0.69 and 0.52 respectively. Subxiphoid pericardial drainage may provide definitive diagnosis and treatment for pericardial effusions. The approach through subxiphoid pericardium under general or local anesthesia avoids the complications of pericardiocentesis and is effective for malignant pericardial effusion.

The objective of this study is to evaluate the anti-cancer and anti-inflammatory activities of plum (Formosa, Oishiwase, Soldam) for the future development of functional food products. To determine the anti-inflammatory effect of different types of plums, the inhibitory effect of plum extracts on nitric oxide (NO) production were measured in lipopolysaccharide (LPS)-stimulated Raw 264.7 mouse macrophage cells and human cancer cell lines (A549, Ags, Hela, Hep3B). Among the three different plum cultivars, Oishiwase at a concentration of 1 mg/mL showed the highest inhibitory effects on NO production (%) in Raw 264.7 macrophage cells. Moreover, Oishiwase exhibited a higher anti-cancer activity against A549 (renal carcinoma, 50%), Ags (gastric carcinoma, 35%), HeLa (cervical carcinoma, 50%), and Hep3B (hepatocellular carcinoma, 31%) at a concentration on 1 mg/mL, respectively, compared to Formosa and Soldam. Our findings suggest Oishiwase plum extracts may serve as potential dietary sources of natural health promoting substances.
