  • Purpose: During the pelvic radiation therapy, it is performed with controlling bladder volume because the range of irradiation is changed depending on the bladder volume. Therefore in this study, we evaluate the accuracy of BVI by tracing the change of bladder volume using ultrasonic pulse diagnosis equipment(BVI 6100, Medical supply Co. LTD) Material and Methods: From January 2017 to September 2018, 19 patients who received pelvic radiation therapy at Pusan National University Hospital were included. To treat the patient, we compared that the bladder volume obtained from the BVI and the bladder volume obtained from the CBCT image then we evaluated for significance. Results: There was a significant correlation of r=0.773, BVI and CBCT in the whole volume section. However, based on the bladder volume in the RTP Image the p value was shown to be 0 at 125~175cc and lower than 0.05 at 175~275cc, And more than 0.05 at 275~375cc. Conclusions: In this study, the patient whose bladder volume is above than 275cc, there is a significance of bladder volume between BVI and CBCT image. However, we could make a decision to be undermined the reliability of BVI measurement in the case of the patient with emptied his urine. Therefore, it is possible to acquire a significant value for 175~275cc patients to use the correction value of BVI and the appropriate tolerance of volume.

  • Purpose: We investigated the effect of location changes in the inferior border of the belly board (BB) aperture by adding a bladder compression device (BCD). Materials and Methods: We respectively reviewed data from 10 rectal cancer patients with a median age 64 years (range, 45~75) and who underwent computed tomography (CT) simulation with the use of BB to receive pelvic radiotherapy between May and September 2010. A CT simulation was again performed with the addition of BCD since small bowel (SB) within the irradiated volume limited boost irradiation of 5.4 Gy using the cone down technique after 45 Gy. The addition of BCD made the inferior border of BB move from symphysis pubis to the lumbosacral junction (LSJ). Results: Following the addition of BCD, the irradiated volumes of SB and the abdominopelvic cavity (APC) significantly decreased ($174.3{\pm}89.5mL$ vs. $373.3{\pm}145.0mL$, p=0.001, $1282.6{\pm}218.7mL$ vs. $1,571.9{\pm}158mL$, p<0.001, respectively). Bladder volume within the treated volume increased with BCD ($222.9{\pm}117.9mL$ vs. $153.7{\pm}95.5mL$, p<0.001). The ratio of irradiated bladder volume to APC volume with BCD ($33.5{\pm}14.7%$) increased considerably compared to patients without a BCD ($27.5{\pm}13.1%$) (p<0.001), and the ratio of irradiated SB to APC volume decreased significantly with BCD ($13.9{\pm}7.6%$ vs. $24.2{\pm}10.2%$, p<0.001). The ratios of the irradiated SB volume and irradiated bladder volume to APC volume negatively correlated (p=0.001). Conclusion: This study demonstrated that the addition of BCD, which made the inferior border of BB move up to the LSJ, increased the ratio of the bladder to APC volume and as a result, decreased the irradiated volume of SB.

  • The tumour necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is considered a promising anticancer agent due to its unique ability to induce cancer cell death having only negligible effects on normal cells. However, many cancer cells tend to be resistant to TRAIL. In this study, we investigated the effects and molecular mechanisms of sodium butyrate (SB), a histone deacetylase inhibitor, in sensitizing TRAIL-induced apoptosis in 5637 human bladder cancer cells. Our results indicated that co-treatment with SB and TRAIL significantly increased the apoptosis induction, compared with treatment with either agent alone. Co-treatment with SB and TRAIL effectively increased the cell-surface expression of death receptor (DR) 5, but not DR4, which was associated with the inhibition of cellular Fas-associated death domain (FADD)-like interleukin-1β-converting enzyme (FLICE) inhibitory protein (c-FLIP). Furthermore, the activation of caspases (caspase-3, -8 and -9) and degradation of poly(ADP-ribose) were markedly increased in 5637 cells co-treated with SB and TRAIL; however, the synergistic effect was perfectly attenuated by caspase inhibitors. We also found that combined treatment with SB and TRAIL effectively induced the expression of pro-apoptotic Bax, cytosolic cytochrome c and cleave Bid to truncated Bid (tBid), along with down-regulation of anti-apoptotic Bcl-xL expression. These results collectively suggest that a combined regimen of SB plus TRAIL may offer an effective therapeutic strategy for safely and selectively treating TRAIL-resistant bladder cancer cells.

  • This study was conducted to determine whether patients could engage in sexual activity following total cystectomy with ileal conduit. Sixteen male bladder cancer patients treated by total cystectomy with or without preoperative irradiation. Patients ranged in age from 48 to 70 years (mean 59.6 years). The interval from therapy ranged from 7 to 82 months (mean 33.8 months).Prior to therapy 11 /16 patients (68.8 %) reported they were engaging some form of sexual activity at least once per month. All were able to achieve an erection and were orgasmic. Following total cystectomy, 6 patients (37.5%) continued to engage in sexual activity at least once per month and were experiencing orgasm. 3 patients (18.8%) reported they were able to achieve an erection. The spontaneous resumptiom of sexual activity by almost one third of the patients in this study refutes the assumption that sexual activity would be impossible following total cystectomy.

  • Objective: To reduce urinary side effects in prostate cancer patients receiving radiation, patients were asked to drink certain amount of water to maintain bladder volume constant and the bladder volumes were measured weekly using ultrasound scanner. Materials and Methods: Twenty-six patients with prostate cancer who received radiation between December 2002 and August 2007 were enrolled in this study. Thirteen patients were enrolled in experimental group. These patients were asked to drink 450 cc of water, one hour prior to simulation, CT scan, and treatment. The other thirteen patients were given no information about bladder filing. Bladder, prostate, and rectum were contoured on CT and volumes were calculated. 3D conformal treatment planning was performed and effective volumes of bladder were calculated when a prescription dose of 70.2 Gy was delivered. For the patients in experimental group, bladder volumes were measured weekly using ultrasound scanner for 6-8 weeks and the bladder volume variations were analyzed. Results: Average bladder volumes and standard deviations obtained at CT scanning were $283.5{\pm}114.0\;cc$ (40%) and $181.2{\pm}120.1\;cc$ (66%) in experimental and control groups, respectively. Although it was not statistically significant, there was correlation between the bladder volumes measured from CT and ultrasound. The volumes measured using ultrasound scanner were 62% lower than the volumes using CT images on average. There was significant variations in volumes measured weekly for 6-8 weeks. It ranged between 33 - 75 %. Conclusion: Our results showed that it is possible to obtain larger bladder volume if they are asked to drink certain amount of water prior to CT scan. However, patients were unable to maintain constant bladder volumes over the 6-8 weeks of treatment period although they were asked to drink constant amount of water.

  • In oriental medicine bladder cancer had been called '溺血(Hematuria)', 血淋(Blood Stranguria)', 濕熱河注(Downward Flow of Damp-heat)' and so on. The symptoms are Hematuria, Oliguria, Lower abdomen pain, febrile sensation and Anemia etc. These are similar to the symptoms of bladder cancer by modem medicine. I have experienced a bladder cancer patient who was diagnosed as stage Ⅲ. She has been treated bladder cancer with Immunity herbal acupuncture and Her clinical and objective symptoms have been better. Therefore I report this results.
