Receiver Operating Characteristic Plot01:15

Receiver Operating Characteristic Plot

476
A ROC (Receiver Operating Characteristic) plot is a graphical tool used to assess the performance of a binary classification model by illustrating the trade-off between sensitivity (true positive rate) and specificity (false positive rate). By plotting sensitivity against 1 - specificity across various threshold settings, the ROC curve shows how well the model distinguishes between classes, with a curve closer to the top-left corner indicating a more accurate model. The area under the ROC curve...

Cancer

53.6K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

What is Cancer?

14.0K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of...

Patient-centered Care01:13

Patient-centered Care

2.9K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Drug Dosing: Obese Patients01:21

Drug Dosing: Obese Patients

232
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Drug Dosing: Geriatric Patients

229
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Summary

Racial and insurance disparities affect brachytherapy use in cervical cancer patients, with minority and lower-income groups receiving it less often. However, these disparities did not impact overall survival rates in the study population.

Area of Science:

  • Oncology
  • Health Services Research
  • Medical Ethics

Background:

  • Brachytherapy is a crucial component of cervical cancer treatment.
  • Understanding disparities in its application is vital for equitable care.
  • Previous research suggests potential inequities in cancer treatment delivery.

Purpose of the Study:

  • To investigate the influence of race and insurance status on brachytherapy utilization for cervical cancer.
  • To identify specific patient demographics experiencing disparities in brachytherapy access.
  • To assess whether these disparities affect overall survival outcomes.

Main Methods:

  • Retrospective cohort study utilizing the National Cancer Database (2004-2015).
  • Inclusion of 25,223 patients with stage IB2-IVA cervical cancer receiving radiation therapy.
  • Statistical analysis including univariate and multivariable regression, and Cox proportional hazards models.

Main Results:

  • Non-Hispanic Black patients had lower brachytherapy rates compared to non-Hispanic White patients (OR 0.93).
  • Uninsured, Medicaid, and Medicare patients were significantly less likely to receive brachytherapy than privately insured patients.
  • Brachytherapy use disparities did not mediate differences in overall survival based on race or insurance status.

Conclusions:

  • Significant racial and insurance-related disparities exist in brachytherapy use for cervical cancer.
  • A notable proportion of patients do not receive this standard of care due to these disparities.
  • Despite access inequities, overall survival was not demonstrably affected by these specific treatment disparities.
