Cancer-Specific Survival of Patients with Non-Muscle-Invasive Bladder Cancer: A Population-Based Analysis

BACKGROUND AND PURPOSE

Non-muscle-invasive bladder cancer (NMIBC) constitutes a heterogeneous group of tumors with different prognoses. This population-based study aimed to report real-world cancer-specific survival (CSS) of NMIBC and create a prognostic nomogram based on the identified risk factors.

METHODS

The Surveillance, Epidemiology, and End Results database was searched for patients diagnosed with NMIBC from 2004 to 2015, who underwent transurethral resection of the bladder tumor. The dataset was divided into development and validation cohorts. Factors associated with CSS were identified using Cox proportional hazards and used to develop a prognostic nomogram.

RESULTS

In total, 98,238 patients with NMIBC were included. At the median follow-up of 124 months (IQR 81-157 months), cancer-specific mortality (CSM) was highest for T1HG (19.52%), followed by Tis (15.56%), similar for T1LG and TaHG (10.88% and 9.23%, respectively), and lowest for TaLG (3.76%). Multivariable Cox regression for CSS prediction was utilized to develop a nomogram including the following risk factors: tumor T category and grade, age, tumor size and location, histology type, primary character, race, income, and marital status. In the validation cohort, the model was characterized by an AUC of 0.824 and C-index that reached 0.795.

CONCLUSIONS

To conclude, NMIBC is associated with a significant risk of long-term CSM especially, but not only, in patients with T1HG. Rarely diagnosed TaHG and T1LG tumors should be regarded as high-risk due to approximately 10% CSM. T category, grading, and age remain the most powerful determinants of CSS in NMIBC, but sociodemographic factors might also influence its prognosis.

Effects of Nursing Care for the Treatment of Patients with Bladder Cancer: A Systematic Review and Meta-analysis

Purpose. In this study, a systematic review and meta-analysis were used to examine the effectiveness of nursing care in the treatment of bladder cancer patients. The platforms of PubMed, Embase, Cochrane Library, and Web of Science were used to conduct a thorough literature search. Methods. The searching approach was used to find the fundamental characteristics of 5 studies. Sample size ranged from 52 to 131,852, and total sample size was 151,166. The study was looked up in PubMed, Embase, and Web of Science, with the most recent search being done in July 2022. Utilizing a standardized form, two independent reviewers gathered pertinent information from research that qualified as literature (17). Review Manager 5.3 used the data to examine the literature. Statistics were deemed significant at $p<0.05$ . Results. We discovered that more bladder cancer patients with T1+T2 tumor stages were receiving nursing care than those with T1+T2 tumor stages were receiving control care (mean difference =1.27, 95% CI: 1.20-1.35, $p<0.00001$ ). The proportion of bladder cancer patients with T3+T4 tumor stage in the nursing care group was lower than the proportion of patients with T3+T4 tumor stage in the control group (mean difference = 1.07; 95% CI: 1.01-1.14; $p<0.00001$ ). The difference between the number of bladder cancer patients receiving radiotherapy in the nursing care group and the control group was not statistically significant (mean difference = 1.07, 95% confidence interval [CI]: 0.99-1.16, $p=0.11$ ). There were fewer patients with bladder cancer receiving chemotherapy in the nursing care group than that in the control group (mean difference = -0.02, 95% CI: -0.0-0.02, $p<0.00001$ ). The incidence rate of patients with bladder cancer with major complications in nursing care group was lower than that of patients with bladder cancer with major complications in control group (mean difference = 0.41 95% CI: 0.18-0.93, $p=0.03$ ). When compared to patients with bladder cancer who had serious complications in the control group, the hospital death rate for nursing care patients had a greater incidence of bladder cancer patients (mean difference = 4.64 95% CI: 4.46-4.82, $p<0.00001$ ). Conclusion. This study demonstrated that the effects of nursing care reduced the incidence rate of chemotherapy and the frequency of severe problems in bladder cancer patients.
