Patient Reported Comparative Effectiveness of Contemporary Intensity Modulated Radiation Therapy Versus External Beam Radiation Therapy of the Mid 1990s for Localized Prostate Cancer.

Introduction: Little is known about differences in patient reported outcomes between contemporary external beam radiation therapy for localized prostate cancer that delivers higher doses of conformal radiation and older techniques. We examined sexual, urinary and bowel function between men undergoing contemporary intensity modulated radiation therapy vs those undergoing external beam radiation therapy in the mid 1990s.

Methods: Subjects were selected from 2 large population based prospective cohort studies.

Variation in the Diagnostic Evaluation among Persons with Hematuria: Influence of Gender, Race and Risk Factors for Bladder Cancer.

Purpose: We sought to determine whether race, gender and number of bladder cancer risk factors are significant predictors of hematuria evaluation.

Materials And Methods: We used self-reported data from SCCS (Southern Community Cohort Study) linked to Medicare claims data. Evaluation of subjects diagnosed with incident hematuria was considered complete if imaging and cystoscopy were performed within 180 days of diagnosis.

The Influence of Psychosocial Constructs on the Adherence to Active Surveillance for Localized Prostate Cancer in a Prospective, Population-based Cohort.

Objective: To evaluate the influence of psychosocial factors such as prostate cancer (PCa) anxiety, social support, participation in medical decision-making (PDM), and educational level on patient decisions to discontinue PCa active surveillance (AS) in the absence of disease progression.

Methods: The Comparative Effectiveness Analysis of Surgery and Radiation study is a prospective, population-based cohort study of men with localized PCa diagnosed in 2011-2012. PCa anxiety, social support, PDM, educational level, and patient reasons for discontinuing AS were assessed through patient surveys.

Validity and reliability of the Patient-Reported Arthralgia Inventory: validation of a newly-developed survey instrument to measure arthralgia.

Background: There is a need for a survey instrument to measure arthralgia (joint pain) that has been psychometrically validated in the context of existing reference instruments. We developed the 16-item Patient-Reported Arthralgia Inventory (PRAI) to measure arthralgia severity in 16 joints, in the context of a longitudinal cohort study to assess aromatase inhibitor-associated arthralgia in breast cancer survivors and arthralgia in postmenopausal women without breast cancer. We sought to evaluate the reliability and validity of the PRAI instrument in these populations, as well as to examine the relationship of patient-reported morning stiffness and arthralgia.

Should mesenteric tumor deposits be included in staging of well-differentiated small intestine neuroendocrine tumors?

Well-differentiated small intestine neuroendocrine tumors can give rise to mesenteric tumor deposits, which are not included in the current American Joint Committee on Cancer staging system for small intestine neuroendocrine tumors, and their impact on patient prognosis is unknown. Seventy-two small intestine neuroendocrine tumors resections were identified in our files with slides, reports, and follow-up data available. Cases were assessed for T-category and for the presence of mesenteric tumor deposits, lymph node metastases, lymphovascular invasion, and liver metastases.
