Demographics and Clinical Variables for Postmastectomy Radiotherapy Study

A retrospective cohort of 57 female patients with pT1-2N1M0 breast cancer treated with mastectomy between 1999 and 2023. The dataset, shared by Raksha M. Narasimhan on figshare, includes variables for analyzing recurrence-free and overall survival outcomes in relation to postmastectomy radiotherapy and other clinical factors.

Use Cases

• Analyze the association between postmastectomy radiotherapy and survival outcomes based on patient cohort data.
• Identify prognostic factors for recurrence-free survival based on variables like nodal burden and hormone therapy.
• Conduct subgroup survival analysis by receptor subtype (TNBC vs non-TNBC) as described in the study.

Strengths

• Includes 57 patient records with a median follow-up of 85 months.
• Contains clinical variables for analyzing survival outcomes, including tumor laterality, receptor subtype, and adjuvant therapies.

Limitations

• The modest sample size of 57 patients limits statistical power, as noted in the study conclusions.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
