Programs
Research: the Gastric Cancer Foundation is the primary source of funding for the gastric cancer registry (gcr) based at stanford medical center. It is the most comprehensive and largest hipaa-compliant registry for this disease. The gcr makes clinical and genomic information available to all researchers free of charge through its open-access genome explorer internet portal. The gcr has over 723 enrolled patients and has uploaded data to the genome explorer from its sequencing of 257 tumor samples. Beyond the gcr, the foundation made two strategic one-year grants to provide seed-funding for promising studies with the potential to bring new treatments to patients.

Website engagement continued to strengthen in 2025, reaching 44,000 page views from over 18,000 users across 22,000 sessions, reflecting broader reach and more frequent visits. The foundation produces an original video series called the gesundheit kitchen that helps patients cope with the unusual nutritional challenges caused by the disease.

We also developed and launched a new video education series called your new normal designed to help highlight key challenges stomach cancer patient face during and after treatment.

The organization over time
Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $631k to $1.0M (+59%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
100% of GASTRIC CANCER FOUNDATION’s revenue is contributions — more reliant on donations than three-quarters of its peers (82% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 13 funders, grant income rose $25k → $144k.
11 of 26 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 69% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of GASTRIC CANCER FOUNDATION’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
GASTRIC CANCER FOUNDATION has a broad base — no single funder exceeds 18% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
72% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund GASTRIC CANCER FOUNDATION.
Largest funder’s share by year: 2017 100% · 2018 100% · 2020 69% · 2021 37% · 2022 30% · 2023 52% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
43% of GASTRIC CANCER FOUNDATION's funders are still giving 3 years after their first grant; 50% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
69% of GASTRIC CANCER FOUNDATION's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $209k that is directly attributable, 51% of it comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $459k arriving through sponsors registered in 8 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
