Comparison of flexible endoscopy and magnetic resonance imaging in determining the tumor height in rectal cancer.

BACKGROUND: Several modalities are available for the diagnosis of rectal cancer, including conventional gold standard rigid endoscopy and recent flexible endoscopy and magnetic resonance imaging (MRI). Each modality affects the management of these patients. AIM: To compare the accuracy of flexible endoscopy and MRI in the measurement of tumor height in patients with rectal cancer. METHODS AND RESULTS: This study included 174 patients with rectal cancer who underwent flexible endoscopy and MRI for the measurement of tumor height. Data on patient demographics, comorbidities, treatment, and histopathology were identified and collected. We evaluate intraclass correlation coefficient (ICC) and Bland-Altman plot to test the agreement between the measurements. ICC were excellent with an ICC of 89% (95%CI 48%-99%). The mean ± standard deviation of the distance from the anal verge to the distal part of the tumor was 7.73 ± .47 for flexible endoscopy and 6.21 ± 0.39 for MRI, with mean difference of 1.52 (p Ë‚ .001). The accordance between the two modalities was not affected by sex, age, body mass index, histopathology, or metastasis. CONCLUSION: Excellent agreement between flexible endoscopy and MRI was noted, and no factor was found to affect such concordance.

Evaluation of participation and performance indicators in a breast cancer screening program in Saudi Arabia.

OBJECTIVES: To evaluate early performance indicators for breast cancer screening at the King Abdulaziz University Hospital in Saudi Arabia. METHODS: This study retrospectively evaluated data from women who underwent their first breast cancer screening program in Jeddah, Saudi Arabia between 2012 and 2019. Data on screening results were used to estimate performance indicators and generate descriptive statistics. RESULTS: Of the 16000 women invited from 2012 to 2019, a total of 1911 (11.9%) participated. The majority of women (68.8%) were between 40 and 55 years old. Based on the screening process results, 26.6%, 40.1%, 9.7%, 1.3%, 0.7%, and 5.2% of women had BI-RADS scores of R1, R2, R3, R4, R5, and R0 respectively. The remaining 16.3% did not have mammogram records. The recall rate, or the percentage of women who underwent further evaluation, was 19.9%; 18.9% underwent a biopsy procedure. In addition, 1.6% of women had cancer screen-detected, although only 0.7% were diagnosed with breast cancer. CONCLUSION: In light of the low participation and high recall rates, it is essential that the screening program utilizes performance indicators to optimize resource utilization and ensure the quality of the service provided. Additionally, a national framework and standardized performance indicators could mitigate this problem for other cancer screening programs.
