Supplementary Material for: Early Perioperative Morbidity After Sentinel Lymph-Node Excisi

A single-center retrospective observational cohort study from January 2013 to December 2024 at a tertiary referral center. The dataset includes 61 patients with pT1b+ penile cancer, comparing early perioperative outcomes between sentinel lymph-node excision and subsequent completion inguinal lymph-node dissection. The research was published on figshare under a CC-BY-4.0 license.

Use Cases

• Compare complication rates between sentinel node biopsy and completion lymph node dissection based on reported Clavien–Dindo scores.
• Analyze length of stay differences between two surgical procedures for node-positive penile cancer.
• Investigate associations between surgical escalation and secondary outcomes like lymphocele, reoperation, and readmission.
• Model perioperative risk for guideline-concordant nodal staging pathways in clinically node-negative patients.

Strengths

• Dataset is focused on a specific, stage-restricted cohort (n=61 patients with pT1b+ disease).
• Outcomes are clearly defined with specific metrics: 30-day major complications and length of stay.
• Analysis includes both paired (within-patient) and unpaired statistical comparisons.
• Temporal coverage is explicitly stated as January 2013–December 2024.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the full dataset is unknown, which may limit suitability assessment.
• Data is from a single tertiary referral center, which may limit generalizability.
