Clinical definition (Orphanet)

Liposarcoma (LS), a type of soft tissue sarcoma, describes a group of lipomatous tumors of varying severity ranging from slow-growing to aggressive and metastatic. Liposarcomas are most often located in the lower extremities or retroperitoneum, but they can also occur in the upper extremities, neck, peritoneal cavity, spermatic cord, breast, vulva and axilla.

How rare: How common this is has not been clearly measured.

Research stages

Trial readiness signals

Where this condition sits on an open-data research pipeline — not how close a treatment is, and not medical advice. Empty stages often mean “not in these databases under this Mondo ID,” not “impossible.”

Biology

Genes and phenotypes

Gene–disease validity from GenCC, plus phenotypes and animal models joined from Monarch Initiative via Mondo ID — not a clinical diagnosis aid.

Do we know what causes it?

Not yet — the cause hasn't been pinned down in GenCC.

No strong gene–disease assertion joined for this Orphanet entity.

Phenotypes (Monarch / HPO)

Not enriched in this build — Monarch phenotype joins were not run for this record.

Animal models (Monarch / Alliance)

Literature

Is anyone studying this?

24,023

24,023 papers — among the better-studied rare conditions, though still a fraction of common-disease literature (breast cancer: over 700,000). Median papers in the last 10 years for a rare disease in this dataset (publications denominator n=5449) is 41.

24,023 papers since the earliest indexed year in this search — median last-10-year count for a rare disease in this dataset is 41 (publications denominator n=5449).

Clinical research

Is a treatment being tested?

134

interventional trials for this specific condition

134 interventional trials matched this specific condition name; 31 currently recruiting in our sample.

Data as of 27 July 2026

134 interventional trials — more than 73% of diseases in the trials denominator have none at all (5114 of 7003; this disease is at the 98.8th percentile).

Recruiting interventional trials

From the matched ClinicalTrials.gov set

134 interventional trials matched after quoted-phrase search and title/condition post-filter.

Observational and natural-history studies

14 observational studies match this condition. These do not test a treatment and are not counted in the interventional-trial headline, but they are genuine research: natural-history work often defines the endpoints needed for a future rare-disease trial, and families may be able to enroll.

Where to find support

We do not yet link condition-specific patient organisations. These umbrella groups support undiagnosed and ultra-rare families:

India — NPRD

Last verified 2026-07-26

This ORPHAcode is not on our curated NPRD list (direct or Mondo-parent match). That does not decide clinical eligibility; families in India should ask a notified Centre of Excellence about current coverage.

Hand-curated for this project. ORPHAcode mappings are best-effort and may be incomplete or imprecise for umbrella categories. Parent (Mondo) matches mean the policy lists a broader category — confirm eligibility with a Centre of Excellence. Financial entitlements summarised from public policy statements and may change. This is not official government guidance.

How we counted this

Europe PMC query (preferred label + any corrected label + Orphanet and Mondo exact synonyms, stoplisted; unioned with resolved MeSH labels when available). UMLS / OMIM / NCIT cross-references are stored on the overview but are not added to the query string.

"Liposarcoma" OR "lip sarcoma" OR "liposarcoma, malignant" OR "sarcoma of lip" OR "sarcoma of the lip"

Run this search on Europe PMC

MeSH descriptor terms unioned into the query: Liposarcoma

ClinicalTrials.gov query (quoted phrases + MeSH via query.cond, plus recall-expansion terms when used):

"Liposarcoma" OR "lip sarcoma" OR "liposarcoma, malignant" OR "sarcoma of lip" OR "sarcoma of the lip"

Interventional trials matched via: both (mesh = registered under a MeSH descriptor no name phrase would catch; recall-expansion = gene / selected parent terms used only for trials).

Study-type breakdown: 134 interventional · 14 observational · 1 expanded access. Only interventional studies enter the trial headline.

Query health: ok — strategies attempted: phrase, mesh; with hits: phrase, mesh

Confidence reasoning

  • Preferred label is short or not clearly distinctive
  • No synonyms dropped by stoplist
  • No label/synonym collisions with other diseases in this corpus
  • Publication count (24023) is extremely high with unknown/missing prevalence — treat as possible over-matching, not proven research intensity
