Key result
Contiguous organ resection significantly improved disease-specific survival compared to palliative surgery or biopsy in patients with primary retroperitoneal liposarcoma (HR 0.328).

May support contiguous organ resection for survival benefit; extends observational data but leaves open need for prospective validation.

Does complete tumor resection improve disease-specific survival compared to palliative surgery or biopsy in patients with primary retroperitoneal liposarcoma?
Hazard Ratio: 0.328 (95% CI 0.135–0.793)
Absolute Event Rate: 53.1% vs 35.8%
p-value: p=0.013
In patients with primary retroperitoneal liposarcoma, complete tumor resection and contiguous organ resection improve disease-specific survival, while high histological grade is strongly associated with local recurrence and poorer prognosis.
Wu et al. (2017) conducted a cohort in Primary retroperitoneal liposarcoma (n=65). Contiguous organ resection vs. Palliative surgery or biopsy was evaluated on Disease-specific survival (HR 0.328, 95% CI 0.135-0.793, p=0.013). Contiguous organ resection significantly improved disease-specific survival compared to palliative surgery or biopsy in patients with primary retroperitoneal liposarcoma (HR 0.328).
