12 genes recurrently implicated in soft tissue sarcoma — TP53, MDM2, CDK4, RB1, PDGFRA, NTRK1, ALK, PDGFRB, NF1, SS18, TERT, CTAG1B — triaged for what can actually be aimed at them, alongside the trials, public datasets, literature and funding around the disease. Every figure below carries its source and retrieval date in the section it comes from.

7
drugs carry an FDA label naming soft tissue sarcoma: Afamitresgene Autoleucel, Dactinomycin, Eribulin, Imatinib, Pazopanib, Tazemetostat and 1 more. This counts labels, not treatment — the disease is also treated with agents approved under broader indications
2
of the 12 genes above carry a drug that is approved in soft tissue sarcoma itself — PDGFRA, PDGFRB. Across all of them 140 drug entries reach these genes, 125 distinct once salt forms are merged
13
registered NY-ESO-1 cell-therapy trials in soft tissue sarcoma, 5 active and 2 withdrawn. Counted from ClinicalTrials.gov across 6 synonyms, deduplicated by NCT id, interventional studies only — the query is published in the JSON beside this page so the number can be re-derived
3
targets carry an Open Targets tractability signal and no trial in soft tissue sarcoma that the searches found (no trial naming a drug Open Targets lists for the gene, none naming it as a cell-therapy target): RB1, NF1, SS18. CTAG1B has cell-therapy trials, so it is undrugged rather than untouched
3,066
human GEO series match the disease; 411 survive on-topic filtering, and only 19 are patient cohorts of 100+ samples
89
Europe PMC full-text papers name GSE30929 — the highest accession-mention count in the set. A mention is not proof of reanalysis, so read it as reach rather than reuse
$33.9M
NIH obligations in FY2025, up 166% since 2013 — while distinct core projects went 20 to 53. Both more projects (+165%) and larger awards, the latter carrying more of the growth; core projects are not the same unit as laboratories

Target landscape

Open Targets · retrieved 2026-09-30 · weekly

12 genes recurrently implicated in soft tissue sarcoma, triaged for whether anything can actually be aimed at them. The zeros are the informative rows.

Of 12 recurrently implicated genes, 9 carry any drug at all. That is a statement about these 12 gene targets, not about the disease: Soft tissue sarcoma does have labelled therapy — 7 drugs, listed in the next section.

Two different questions

The table below asks what can be aimed at 12 recurrently implicated genes. That is narrower than what is approved for the disease, and narrower again than what soft tissue sarcoma is actually treated with, which includes agents approved under broader indications. All three are on this page and they are kept apart deliberately.

Cell therapy against NY-ESO-1

ClinicalTrials.gov · retrieved 2026-09-18 · weekly

NY-ESO-1 is the busiest cell-therapy target among those this briefing searched in soft tissue sarcoma: 13 registered trials naming it, 5 still active, 2 withdrawn before enrolling anyone. It has no gene entry of its own and is reached through CTAG1B: a cancer-testis antigen presented on HLA-A2 and reached by engineered T cells; afamitresgene autoleucel is approved for synovial sarcoma.

Research momentum

PubMed MeSH · monthly

Every term below is a share of the soft tissue sarcoma literature, not a count, because the field itself grew: 2015–2018 (n=6,000) against 2021–2025 (n=6,000). A topic whose papers doubled while the field doubled has not risen.

These are sample shares. The two windows hold 6,966 and 9,493 papers; MeSH terms were read from an evenly spaced sample of 6,000 and 6,000 of them, taken across the whole window rather than from its most recent papers. Percentages carry sampling error of roughly a percentage point and small differences between two terms are not meaningful.

Years of life lost (proxy)

5.3 years per case, 73,475 a year, from survival and age at diagnosis rather than from a death count. derived proxy Not the WHO/GBD measure, which uses age at death and a life table; comparable across these briefings, not with published YLL figures. What this costs to fund is in Funding.

3 assumptions behind this estimate
  • Five-year relative survival stands in for cure; a death after five years is not counted.
  • The median age at diagnosis stands in for the whole age distribution.
  • Life expectancy at birth (78.4 years) is the reference, rather than remaining expectancy at the age of death from a life table.
  • Each assumption moves the result by more than the difference between the two diseases currently on this site, so this figure separates a disease from one ten times its size, not from a close neighbour.

Where the gaps are

Derived from the sections above · recomputed on every refresh

Each card below is a disagreement between two of the tables on this page — a drug that exists but was never tried here, a target that looks tested and was not, a gene with no drug whose product has a busy clinical programme. They are computed from the same facts as the tables, so they cannot contradict them.

RB1

Open Targets lists no drug against it and no trial in soft tissue sarcoma names it. A bounded negative: the sources and search terms are in the JSON beside this page.

NF1

Open Targets lists no drug against it and no trial in soft tissue sarcoma names it. A bounded negative: the sources and search terms are in the JSON beside this page.

SS18

Open Targets lists no drug against it and no trial in soft tissue sarcoma names it. A bounded negative: the sources and search terms are in the JSON beside this page.

TERT

1 registered trial, 1 withdrawn before enrolling anyone and none active. This target reads as tried; it was not.

CTAG1B

13 cell-therapy trials against NY-ESO-1, 5 active, and no approved product. The clinical activity is real and none of it has reached a label.

How a machine reads this page

Static

This page is written to be quoted correctly by a model as much as read by a person. The same facts are available as JSON at the sibling URL below, which is what to cite. The cross-disease layer — burden, genes, drugs and antigens across every briefing — is described at /disease/api.json.

Fully server-rendered

Every figure is in the HTML at first byte. No JavaScript runs, no figure is fetched after load, and nothing on this page requires a renderer to see.

Every number carries a source

Each section names the API it came from and the date it was retrieved: Open Targets (2026-09-30), ClinicalTrials.gov (2026-09-18), openFDA (2026-09-18), NCBI GEO (2026-09-19), PubMed (2026-09-12), NIH RePORTER (2026-09-19).

Negatives stated explicitly

Where the searches find nothing for soft tissue sarcoma — no drug, no trial, no approval — the page says so in those words rather than omitting the row, and names the source searched. An absent row is unquotable; a bounded negative is the finding.

Denominators, not just percentages

Every share is printed with the count and the total it came from, so a figure can be checked rather than taken.

The filters are published

4 exclusion patterns are applied to free text before anything is ranked, because HT-1080 is used as a model system in cell invasion, matrix-degradation and gelatin-zymography assays across cancer biology. What was removed and why is stated in each section rather than silently applied.
