Genomic Risk in Retroperitoneal Sarcoma

Characterization of the Genomic Risk Underlying Retroperitoneal Liposarcoma

Who can join

Ages 18 and older · All sexes · Healthy volunteers welcome

Inclusion Criteria:

* Adult patients (age ≥18 years).
* Histologically confirmed retroperitoneal liposarcoma via preoperative biopsy, or cross-sectional imaging suspicious for liposarcoma with planned surgical resection
* Will be undergoing surgical resection for treatment of primary or recurrent disease
* Have provided informed consent to participate in this study

Exclusion Criteria:

• Prior surgical anatomy which makes sampling of remote areas of the retroperitoneum technically impossible or clinically undesirable for safety reasons

About the study

The protocol intends to explore the biology which may underlie recurrences of retroperitoneal liposarcoma. Surgery remains the only curative intent intervention for this disease. Often, tumors recur in locations within the retroperitoneum remote from the original primary tumor. This study hypothesizes that normal appearing retroperitoneal fat actually harbors underlying genetic changes which predispose to development of future liposarcoma. To accomplish this goal, retroperitoneal fat is sampled from quadrants within and remote from the primary tumor and is subsequently subjected to genetic analyses looking for such predisposing factors.
