Objectives: We investigated the accuracy of clinical breast carcinoma anatomic staging and the greatest tumor dimension measurements.
Methods: We compared clinical stage and greatest dimension values with the pathologic reference standard values using 57,747 cases from the 2016 US National Cancer Institute Surveillance, Epidemiology, and End Results program who were treated by surgical resection without prior neoadjuvant therapy.
Results: Agreement for clinical vs pathologic anatomic TNM group stage, overall, is 74.
Article Synopsis
- The study aimed to assess cosmetic outcomes after administering stereotactic partial breast irradiation (S-PBI) in 75 women with early-stage breast cancer.
- Most participants reported good cosmetic results at both the beginning of the study and three years later, with no significant decline noted across different radiation dose levels.
- The findings suggest that increasing the dose of S-PBI does not negatively impact cosmetic appearance, indicating its viability as a treatment option for early-stage breast cancer.
Simplified, standardized methods to assess the accuracy of clinical cancer staging.

Background: Hospitals lack intuitive methods to monitor their accuracy of clinical cancer staging, which is critical to treatment planning, prognosis, refinements, and registering quality data.
Methods: We introduce a tabulation framework to compare clinical staging with the reference-standard pathological staging, and quantify systematic errors. As an example, we analyzed 9,644 2016 U.
Rationale And Objectives: Examine the accuracy of clinical non-small cell lung cancer staging and tumor length measurements, which are critical to prognosis and treatment planning.
Materials And Methods: Compare clinical and pathological staging and lengths using 10,320 2016 National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) and 559 2010-2018 non-SEER single-institute surgically-treated cases, and analyze modifiable causes of disagreement.
Results: The SEER clinical and pathological group-stages agree only 62.
Purpose: To survey the radiation oncology residency program directors on the topics of departmental and institutional support systems, residency program structure, Accreditation Council for Graduate Medical Education (ACGME) requirements, and challenges as program director.
Methods: A survey was developed and distributed by the leadership of the Association of Directors of Radiation Oncology Programs to all radiation oncology program directors. Summary statistics, medians, and ranges were collated from responses.
