  • A 10-year-old spayed female Pomeranian dog weighing 3.65 kg was presented with a 7-month history of urinary incontinence, stranguria and hematuria. The patient had mass lesions at left prescapular region ($3cm{\times}3cm$) and left axillary region ($5cm{\times}4cm$). Diagnosis of transitional cell carcinoma (TCC) with multiple cutaneous metastasis was made. Dog was treated with chemotherapy using mitoxantrone and piroxicam for 5 months. Although TCC size of urinary bladder was decreased during chemotherapy, there was no change of subcutaneous tumor size and mild relief of clinical signs. Partial anorexia for 3 weeks and multiple masses were noted at left caudal abdominal wall and left medial thigh (203 days after first presentation) and assessed as chronic kidney disease and additional subcutaneous metastasis of urinary bladder TCC by post-mortem and histopathological findings.

  • Genistein, a natural isoflavonoid phytoestrogen, is a strong inhibitor of protein tyrosine kinase and DNA topoisomerase activities. There are several studies documenting molecular alterations leading to cell cycle arrest and induction of apoptosis by genistein as a chemopreventive agent in a variety of cancer cell lines; however, its mechanism of action and its molecular targets on human bladder carcinoma and leukemic cells remain unclear. In the present study, we have addressed the mechanism of action by which genistein suppressed the proliferation of T24 bladder carcinoma and U937 leukemic cells. Genistein significantly inhibited the cell growth and induced morphological changes, and induced the G2/M arrest of the cell cycle in both T24 and U937 cells with a relatively stronger cytotoxicity in U937. The G2/M arrest in T24 cells was associated with the inhibition of cyclin A, cyclin B1 and Cdc25C protein expression without alteration of tumor suppressor p53 and cyclin-dependent kinase (Cdk) inhibitor p21(WAF1/CIP1). However, the inhibitory effects of genistein on the cell growth of U937 cells were connected with a marked inhibition of cyclin B1 and an induction of Cdk inhibitor p21 proteins by p53-independent manner. These data suggest that genistein may exert a strong anticancer effect and additional studies will be needed to evaluate the different mechanisms between T24 and U937 cells.

  • Purpose: Despite numorous reports on the relationship between the level of carcinoembryonic antigen (CEA) in gall bladder bile and liver metastasis in colorectal cancer, no similar studies have been carried out for gastric carcinomas. We, therefore, undertook the present study to establish the relationship between the gall bladder bile CEA and liver metastasis as well as the post-operative survival rate in gastric carcinoma patients with curative resections. Materials and Methods: In 373 gastric cancer patients (252 males, 121 females, age $21\∼76$ years) operated on at Kosin University Hospital between 1989 1996, the CEA concentration in the gall bladder bile was determined during the operation and the value was related to the rates of post-operative survival and liver metastasis during follow-up period. Results: The overall rate of patient survival decreased gradually with increase in TNM stage. The 13-year postoperative survival rates for stages Ia, Ib, II, IIIa, and IIIb were $95.7\%,\;92.5\%,\;79.9\%,\;50.9\%,\;and\;43.3\$, respectively, and the 10-year survival rate for stage IV was $22.6\%$. The patients with a high ($\geq$10 ng/ml) biliary CEA showed a significantly lower rate of survival than those with a low (<10 ng/ml) biliary CEA. The 13-year cumulative survival rate was $55.4\%$ for the high CEA group and $76.5\%$ for the low CEA group (P<0.01). Also, the patients with a high biliary CEA showed a significantly higher rate ($11.5\%$) of liver metastasis than those with a low biliary CEA ($1.9\%$) (P<0.000). In patients with TNM stages (I and II), the CEA level did not affect the post-operative survival rates ($95.4\%\;and87.7\%$ in the high and low CEA groups, P>0.10), but in those with high TNM stages (III and IV), the survival rate was significantly lower in the high CEA group ($25.9\%$) than in the low CEA group ($57.8\%$) (P<0.05). Conclusion: These result suggest that the gall bladder bile CEA level obtained in an advanced-staged gastric cancer operation may be used in predicting the post-operational survival rate and in sorting out patients with a high risk for cancer recurrence, especially in the liver area.

  • Clinical estimation of bladder and rectal doses from high dose rate intracavitary irradiation in carcinoma of the cervix uteri has been initiated on a routine basis in an effort to obtain the optimum radiotherapeutic dose. Simulation films with contrast media are used to image the bladder and rectum, and dose rates are estimated at various interesting points with the aid of treatment planning computer, NEC Therac-2300. Fifty-three patients have been reviewed in order to ascertain the correlation between radiation dose at interesting points in the bladder and rectum and the dose at Point A and B. The dose ratio between doses at Point A 'and interesting points is an important clinical factor in evaluating the treatment planning. This also serves as documentation of the dose to normal structures within the treatment volume. Authors conclude that obtained data are within acceptable ranges and routine simulation films of the bladder and rectum after administration of contrast media with dose calculations at interesting points provide important information for optimizing radiotherapy planning in the treatment of cervical carcinoma without increased time and effort or patient's discomfort.

  • Background: Urological cancers represent a major public problem associated with high mortality and morbidity. The pattern of these cancers varies markedly according to era, region and ethnic groups, but increasing incidence trends overall makes focused epidemiological studies important. The aim of the present study was to assess the incidence of most prevalent urological cancers in Iran from 2003 to 2009. Materials and Methods: The data for this study were obtained from the population-based Cancer Registry Center of the Iran Ministry of Health and Medical Education. Differences of mean age and age distributions of each cancer were compared between 2003 and 2009 in men and women. Results: Bladder cancer was the most common urologic cancer in both genders. The rate difference of age standardized ratio (ASR) of bladder and renal cell carcinoma in women were 1.54 and 2.01 percent per 100,000 population from 2003 to the 2009, respectively. In men, the rate difference of age standardized ratio of prostate, testis, kidney and bladder cancer was also 2.23, 1.2, 1.8 and 1.5 percent per 100,000 population from 2003 to 2009, respectively. The mean ages of patients in all cancers in both genders did not differ significantly through time (p value>0.05) but the distribution of ages of patients with bladder and prostate cancer changed significantly from 2003 to 2009 (p value<0.001). Conclusions: The results of present study suggest the general pattern and incidence of urological cancers in Iran are changing, the observed increase pointing to a need for urological cancer screening programs.

  • Background: To explore the expression of DcR3 protein and its clinicopathological significance in bladder urothelial carcinomas (BUC). Materials and Methods: Immunohistochemistry was performed to detect the expression of DcR3, caspase-3, Bcl-2, VEGF, Ki-67, PCNA and P53 in 166 BUC and 56 normal bladder tissues. Western blotting was used to detect the expression of DcR3 in the supernatants of cultured BUC cells. Results: Overexpression of DcR3 was found in BUC tissues and cell lines, with significant elevation as compared to normal bladder tissues (p<0.0001). Higher DcR3 expression was related to the status of invasion, lymph node metastasis and recurrence. Furthermore, DcR3 expression was negatively correlated with caspase-3 and positively associated with Bcl-2, VEGF, Ki-67 labeling index (LI), PCNA LI and P53 (all p<0.0001), respectively. Conclusions: DcR3 may play a crucial role as an oncogene in tumorigenesis, deterioration and progress of BUC via influencing related pathways of apoptosis, proliferation and angiogenesis. The detection of DcR3 protein in the formalinfixed and paraffin-embedded samples could assist to predict in prognosis of BUC patients.

  • Background: Anemia is the most common hematologic abnormality in bladder cancer (BC) patients. We evaluated the impact of preoperative anemia on oncologic outcomes in BC undergoing transurethral resection of a bladder tumor (TURBT) for the first time diagnosis. Materials and Methods: We retrospectively evaluated the data collected from 639 patients who underwent TURBT between January 2006 and September 2014 in our department. Of these patients, 320 qualified for inclusion in the study. The primary efficacy endpoint was the effect of preoperative anemia status on cancer-specific and overall survival. Independent t-test and chi-square analyses were performed to assess the effects of anemia on oncologic outcomes. Survival was estimated by using the Kaplan-Meier test. Results: There were 118 (36.9%) and 202 (63.1%) patients in the anemia (Group-1) and non-anemia groups (Group-2), respectively. The median follow-up duration was 68 months. Anemia was associated with decreased overall survival (p<0.001). Comparison between cancer-specific survival of two groups did not show any statistically significant difference (p=0.17). Conclusions: Preoperative anemia status of BC patients according to World Health Organization classification is associated with decreased overall survival, but not with cancer-specific survival. We think that preoperative hemoglobin levels should be considered in patient counseling and decision-making for additional therapy.

  • In this study, we investigated citrus Kombucha (CK) produced by three different bacteria strains (Gluconacetobacter xylinus, Gluconacetobacter medellinensis, and Gluconobacter oxydans; named as CK-MOX) identified from traditional Kombucha. During fermentation, the pH level of CK-MOX was gradually reduced, and total acidity slightly increased. Antioxidant activity, measured by DPPH, ABTS, and oxygen radical absorbance capacity assays, markedly increased after fermentation. Moreover, fermented CK-MOX (Day15) exhibited anti-proliferative and anti-migratory activities against EJ human bladder carcinoma cells. Western immunoblot assays showed that treatment with CK-MOX significantly up-regulated phospho-extracellular signaling kinase (ERK) levels. To distinguish whether or not up-regulation of phospho-ERK is the cause or effect, we investigated the viability of EJ cells in the presence of U0126, a mitogen activated protein kinase/ERK kinase 1/2 inhibitor. Pre-treatment with U0126 rescued cells from CK-MOX-induced cell death, which indicates phospho-ERK may be a key regulator in the mechanism of CK-MOX-induced apoptosis of EJ bladder cancer cells. In conclusion, CK-MOX, fermented by a defined composition of bacterial starters, shows antioxidant capacity and anti-cancer activity against EJ bladder cancer cells.

  • Cohesin is a multi-protein complex composed of four core subunits (SMC1A, SMC3, RAD21, and either STAG1 or STAG2) that is responsible for the cohesion of sister chromatids following DNA replication until its cleavage during mitosis thereby enabling faithful segregation of sister chromatids into two daughter cells. Recent cancer genomics analyses have discovered a high frequency of somatic mutations in the genes encoding the core cohesin subunits as well as cohesin regulatory factors (e.g. NIPBL, PDS5B, ESPL1) in a select subset of human tumors including glioblastoma, Ewing sarcoma, urothelial carcinoma, acute myeloid leukemia, and acute megakaryoblastic leukemia. Herein we review these studies including discussion of the functional significance of cohesin inactivation in tumorigenesis and potential therapeutic mechanisms to selectively target cancers harboring cohesin mutations.

  • Purpose: FGF4 (fibroblast growth factor 4) is a newly characterized gene which was found to be a transforming gene in several cancerous cells. FGF4 expression and amplification has been subsequently observed in several human cancers including stomach cancer, breast cancer, head and neck squamous cell carcinoma, lung cancer and bladder cancer. This study was designed to measure the protein expression of FGF4 in malignant skin cancers. Methods: We examined 8 normal skin tissues and 24 malignant skin tumor tissues which were 8 malignant melanomas, 8 squamous cell carcinomas and 8 basal cell carcinomas. The specimens were analyzed for the protein expression of FGF4 using immunohistochemical staining. To evaluate the amount of expression of FGF4, the histochemical score (HSCORE) was used. Results: FGF4 was expressed more intensely in malignant melanoma, followed by SCC and BCC in immunohistochemistry. The average HSCORE was 0.01 for normal skin, 2.02 for malignant melanoma, 1.28 for squamous cell carcinoma, and 0.27 for basal cell carcinoma, respectively. The expression of FGF4 in malignant melanoma and squamous cell carcinoma was increased in comparison with normal tissues and basal cell cancer, and the difference was statistically significant (p<0.05). The difference between malignant melanoma and squamous cell carcinoma was not statistically significant. Conclusion: These findings provide evidences that the expression of FGF4 plays an important role in malignant melanoma and squamous cell carcinoma progressions. This article demonstrates expression of FGF4 in human skin malignant tumors, and suggests that FGF4 is more expressed in highly aggressive skin tumors.
