Two-Step vs One-Step Surgery Outcomes for Head and Neck Skin Cancer, 2010-2020

225 patients with non-melanoma skin cancer were treated between 2010 and 2020 to compare surgical methods. Gerlind Schneider's study found a 4.9% overall final positive resection margin rate, with all cases occurring in the one-step surgery group. The median follow-up time was 17.5 months, with 33 local recurrences observed.

Use Cases

• Compare recurrence-free survival rates based on one-step versus two-step surgery methods described in the study
• Analyze risk factors for tumor recurrence based on variables like cancer type (BCC vs cSCC) and subsequent cancers
• Model the impact of surgical approach on complete resection rates (R+ status) as reported in the results
• Assess complication rates (re-surgery due to bleeding/infection) between the two surgical strategies

Strengths

• Includes data for 225 patients with a median age of 77 years and a 68% male demographic split
• Provides specific hazard ratios from multivariate Cox regression for key risk factors like cSCC (HR=6.838)
• Reports clear temporal coverage from 2010 to 2020 with a median follow-up of 17.5 months
• Contains detailed outcome metrics including recurrence times (105.0 vs 126.7 months) and R+ rates (23.2% vs 42.3%)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for large-scale ML
• Data may reflect temporal and institutional bias inherent to a single study on figshare
