Background:
The effect of radical hysterectomy for patients with cervical cancer on voiding function remains controversial. The purpose of this study was to examine the association between radical hysterectomy for patients with cervical cancer and the odds of developing neurogenic bladder by using data from the National Health Insurance Research Database (NHIRD) in Taiwan.
Methods:
We identified 17 936 patients who underwent radical hysterectomy for cervical cancer between 2000 and 2013 among inpatients registered in the Longitudinal Health Insurance Database in Taiwan. Of the patients, those diagnosed as having cervical cancer without radical hysterectomy were selected and compared as a matched control group. Patients diagnosed as having cervical cancer before the index date, those with neurogenic bladder dysfunction before tracking, and those aged <20 years were excluded. The hazard ratios (HRs) of neurogenic bladder and other variants of interest were further calculated using a multivariate Cox regression analysis. The cutoff p value of <0.05 was regarded as statistically significant.
Results:
The adjusted HR (aHR) of subsequent neurogenic bladder was higher in the hysterectomy group (aHR = 1.205; 95% CI, 1.086-1.440; p = 0.029) than in the control group during the follow-up period. As to the age subgroups, the patients aged 20 to 44 years (aHR = 3.321, p = 0.001) had a significantly increased risk of developing neurogenic bladder after radical hysterectomy as compared with those aged 45 to 64 years (aHR = 1.193, p = 0.012).
Conclusion:
Patients with cervical cancer undergoing radical hysterectomy have an increased risk of neurogenic bladder, which may result from nerve denervation caused by the operation. These patients should be informed of the potential risk of voiding dysfunction during discussion of the subsequent management for cervical cancer.
The short- and long-term OS rates of the three modalities were similar in those older than 76 years. Therefore, patients younger than age 76 years are likely to have a better outcome undergoing radical cystectomy for advanced UCB.
Objective This study was performed to compare the efficacy of intravesical mitomycin C (MMC) instillation for the prophylaxis of Ta or T1 high-risk nonmuscle invasive bladder cancer (NMIBC) using different schedules.
Materials and methods This retrospective cohort study was conducted on 152 patients treated with intravesical MMC from April 2009 to September 2016. The mean follow-up time was 32.67 months. All patients underwent a complete transurethral resection of bladder tumor (TURBT) and postoperative instillation of MMC within 24 h. The patients were divided into 4 treatment groups: Group 1 was followed-up without any maintenance MMC dose treatment; Group 2 received an MMC instillation once per week for the first 8 weeks; Group 3 received an MMC instillation once per week for the first 8 weeks, and once per month for the following 6 months; and Group 4 received an MMC instillation once per week for the first 8 weeks, and once per month for the following 12 months.
Results The overall recurrence rate was 27.6 %. Group 1 had a significantly high (p < 0.05) recurrence rate of 50 %, while there was no difference in the recurrence rate between the last 3 schedules (Group 2:15 %; Group 3: 24.1 %; group 4: 27.2 %). Moreover, the recurrence rates of Ta or T1 tumors, and low-grade or high-grade tumors were not statistically different among these patient groups.
Conclusion Our comparison of the different schedules of intravesical MMC instillation revealed a significantly higher recurrence rate with one MMC instillation post-TURBT than in patients with a maintenance dose of 8 weeks, 6 months, and 12 months. The time of the MMC maintenance schedule exhibited no significant differences between 8 weeks and 12 months. Thus, we conclude that for T1 or Ta high-risk NMIBC, MMC instillation can be performed once after TURBT, followed by a maintenance treatment once per week for 8 weeks.
Over 70% of LUTS patients in this study suffered from sexual dysfunction. Although age and diabetes were associated with sexual dysfunction, LUTS severity was not.
5050 Background: Docetaxel has poor oral bioavailability in part due to extrusion by intestinal p-glycoprotein. To improve IV solubility, it is fomulated with the nonionic surfactant polysorbate 80, requiring steroid premedication to manage hypersensitivity type reactions. Oral administration has the potential to improve tolerability, reduce day-stay utilization and improve patient convenience and allows investigation of alternative dosing schedules. Oradoxel is a new combination of oral docetaxel capsules plus the novel gut-selective P-glycoprotein inhibitor encequidar (HM30181A). Methods: Patients with mPC receiving IV docetaxel were enrolled in 3 cohorts with a dose escalation schedule of Oradoxel 75 mg/m2 in Cohort 1, 150 mg/m2 in Cohort 2, 300mg/m2 in Cohort 3. Oradoxel was given 3 weeks before or after IV docetaxel treatment. Intensive PK samples were taken on days 1-5 for Oradoxel and days 1-4 for IV docetaxel. Dose limiting toxicity (DLT) or serious adverse events (SAE) were assessed per CTCAE v4.03. Results: 3 evaluable patients in each Cohort were studied. No DLT, MTD, or drug-related SAE were observed. PK parameters of Oradoxel vs IV docetaxel are summarized in the table below. Mean absolute bioavailability of Oradoxel was 15.9% (range 8-25%). PK became non linear at 300mg/m2. Conclusions: Oradoxel was well tolerated. Based on the results of this and related studies, Oradoxel 300mg/m2 in divided doses is being further evaluated in phase 2 studies. Clinical trial information: 12616000983404. [Table: see text]
Epidermoid cyst is a rare benign tumor of the testes. The records from the last 20 years of Taiwanese patients in whom a testicular tumor was diagnosed were reviewed retrospectively. Patients with a confirmed epidermoid cyst of testis were evaluated for age, clinical assessment and follow-up. Among a total 146 testicular tumors, 28 (19%) patients had a benign tumor including 15 patients (10%; mean age 23 years, range 17-32 years) with an epidermoid cyst diagnosed pathologically. Pre-operative suspicion of the benign nature of the lesions was supported by testicular ultrasonography in 11 patients. Seven patients underwent magnetic resonance imaging after which benign epidermoid cyst was impressed in five patients. A testicular-sparing operation was performed in 12 patients after frozen sections confirmed the diagnosis. Three patients were treated by radical orchiectomy. There was no relapse after a median follow-up of 42 months (range, 2-82 months). Ultrasonography and magnetic resonance imaging of the scrotum may allow the diagnosis of epidermoid cyst of the testes to be made pre-operatively. The absence of relapse in these patients further supports the use of organ sparing surgery in these young men.
