Esophageal cancer: research and therapeutic landscape

12 genes recurrently implicated in esophageal cancer, 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: Esophageal cancer does have labelled therapy — 11 drugs, listed in the next section.

Dataset evidence counts studies in the 428-study ranked set whose title or abstract names the gene; the bar is scaled to EGFR. Sources: Open Targets Platform and NCBI GEO, retrieved 2026-09-12. Clinical stage is the highest reached for any indication — see the per-drug indications noted in each row. Target-prioritisation reference only; not clinical or prescribing guidance.

11 drugs carry an FDA label naming esophageal cancer: Durvalumab, Fam-Trastuzumab Deruxtecan-Nxki, Ipilimumab, Nivolumab, Pembrolizumab, Porfimer, Tislelizumab, Trastuzumab, Trifluridine And Tipiracil, Zanidatamab, Zolbetuximab. Separately, 45 of the drugs returned for the genes in the table above are approved only for other diseases and reach esophageal cancer through trials, not through their labels.

Every label that names esophageal cancer

100 labels match indications_and_usage:"esophageal cancer" OR indications_and_usage:"esophageal carcinoma" OR indications_and_usage:"esophageal squamous" OR indications_and_usage:"esophageal adenocarcinoma" OR indications_and_usage:"gastroesophageal junction"; they collapse to 13 distinct molecules once salt forms, biosimilars and co-formulated hyaluronidase are merged. Source: openFDA drug label API (api.fda.gov/drug/label.json), retrieved 2026-09-12. Labels change; this reflects the current label text, not the approval history. Not prescribing guidance.

PD-1 is the busiest cell-therapy antigen in esophageal cancer: 6 registered trials, 1 still active, 1 withdrawn before enrolling anyone. It has no gene entry of its own and is reached through PDCD1: the checkpoint receptor PDCD1 encodes, on the T cell.

6 of 6 shown, most recently active first. Other antigens searched: CLDN18.2 (1). Source: ClinicalTrials.gov API v2, retrieved 2026-09-12. Trials are matched on the antigen named in the title or intervention, so a trial stating only a product code is missed.

Every term below is a share of the esophageal cancer 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 7,838 and 11,973 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.

Publication mix

Query: Esophageal Neoplasms[MeSH Major Topic] NOT ("Esophageal Achalasia"[MeSH] OR "Eosinophilic Esophagitis"[MeSH]). Terms need at least 12 papers in the recent window and, in the rising table, at least 5 in the earlier one — a term going from 1 paper to 12 is a large fold change and no evidence of anything. Ubiquitous descriptors (Humans, Animals, age bands) and the disease’s own term are dropped. Windows are read whole where they fit and sampled where they do not; the totals and the sample sizes are both in the JSON beside this page. Source: PubMed MeSH, retrieved 2026-09-12.

Years of life lost

7.3 years per case, 164,766 a year, from survival and age at diagnosis rather than from a death count. derived proxy What this costs to fund is in Funding.

NIH obligations naming esophageal cancer, after removing the 1,732 records across all years that matched the search but are about something else. That filter is not cosmetic: without it this section reports another field’s funding as this disease’s.

NIH obligations by fiscal year

Where FY2025 money went

Text search esophageal cancer over project title, terms and abstract, per fiscal year. Awards are individual funding actions; distinct projects collapse them by core project number, so a multi-year grant counts once. The most recent year may be incomplete. Source: NIH RePORTER, retrieved 2026-09-12.

What that buys

Against 164,766 years of life lost a year, FY2025 obligations are $260 per life-year — $1,904 per case. The estimate and its assumptions are in Disease burden.

Who funds it, FY2025

The total says how much. These say who from, through what kind of award, and to whom — which a dollar figure cannot.

729 human GEO series match esophageal cancer. Keyword relevance cannot tell a 360-sample patient cohort from a six-well cell-line experiment, so this ranking scores four things GEO does not expose: how often the accession is named in full-text papers, field-normalised citation impact, clinical annotation, and cohort type.

Composition of the 428-study ranked set

Sources: NCBI GEO + Europe PMC + iCite, retrieved 2026-09-12. SubSeries are collapsed to one row per study by linked PMID. Of 729 series retrieved, 11 were dropped by the profile’s exclusion rules and 203 named the disease only in passing. The ranked set is a relevance-ranked sample, not a census, so the composition figures describe the sample only.

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.

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.
