Outcomes

Primary Outcomes

R1 resection rates

In this retrospective study, R1 resections were defined as cases requiring a follow-up surgery due to incomplete tumor removal.

Time frame: 3 years

Secondary Outcomes

Weight of main specimen

The weight of the main specimen was recorded immediately after excision at the time of surgical removal.

Time frame: Day of excision

Duration of surgery

Time frame: During surgery

Number of Shavings

Number of shavings was recorded intraoperatively, with each shaving representing additional tissue removed to achieve clear margins.

Time frame: During surgery
