SWOG is the cancer clinical trials research network that began in 1956 as the Southwest Cancer Chemotherapy Study Group and now operates as the SWOG Cancer Research Network. It is one of the groups inside the National Cancer Institute’s National Clinical Trials Network (NCTN). This page is for research administrators, site coordinators and trainees who need to place SWOG correctly: what it stands for, where it sits in NCI-funded research, and how a hospital becomes a member. It covers the cancer research network only. General information, not medical advice; people considering a trial should talk to their own care team.
What is SWOG and who runs it?
SWOG is a publicly funded cancer clinical trials network. Its own history page describes it as the nation’s oldest and largest publicly funded cancer research network and says it operates within the NCI’s NCTN. Its stated goal is to “significantly improve lives through cancer clinical trials and translational research” (swog.org, as described on the official pages on 2026-11-07).
What does SWOG stand for in cancer research?
The letters trace back to the original name. SWOG’s history page describes this sequence: Southwest Cancer Chemotherapy Study Group, then Southwest Oncology Group, then SWOG, then (in 2018) SWOG Cancer Research Network. The group was founded in Houston in 1956 by pediatrician Grant Taylor, MD, under a new NCI program testing childhood cancer treatments. Today the name is used as a standalone brand rather than an expansion of the letters.
What is a cancer study called?
A study that tests a cancer treatment, prevention method or other intervention in people is called a clinical trial. SWOG’s network coordinates clinical trials and translational research, which is laboratory-based work linked to those trials. For how trial data are reported publicly, see clinical trial transparency.
What does SWOG mean in shipping?
This page does not cover any logistics or shipping use of the letters. Everything here refers to the SWOG Cancer Research Network, the NCI-funded trials group.
Scale and track record, as stated by SWOG
SWOG’s history page says its members include more than 20,000 people at more than 1,300 hospitals, clinics and cancer centers, in 46 US states and 8 other countries. It credits its trials with leading to FDA approval of 15 new cancer therapies, with changing standards of care more than 100 times, and with saving more than 3 million years of life. These are SWOG’s own figures, read on 2026-11-07. The home page counters on the same date showed 46 enrolling trials, 1,346 member sites and 249,089 patients enrolled; they change as the network enrolls.
Where SWOG sits in the NCTN
The NCI describes the NCTN as a collection of organizations and clinicians that coordinate NCI-funded cancer trials, with more than 2,200 sites. Its core groups, as listed on the NCI NCTN page (read 2026-11-07), are:
| NCTN group | Listed by NCI as |
|---|---|
| Alliance for Clinical Trials in Oncology | NCTN group |
| ECOG-ACRIN | NCTN group |
| NRG Oncology | NCTN group |
| SWOG | NCTN group |
| Children’s Oncology Group | NCTN group |
| Canadian Cancer Trials Group (CCTG) | Canadian Collaborating Clinical Trials Network |
The NCI page also says 32 US academic institutions hold Lead Academic Participating Site (LAPS) grants, and that community hospitals join through affiliations or through the NCI Community Oncology Research Program (NCORP). For billing and regulatory support that runs alongside NCTN trials, see the guide to the Cancer Trials Support Unit (CTSU), and for how NCTN trials measure response, see RECIST endpoints in NCTN oncology trials.
Who can join: the three membership programs
SWOG’s “Join SWOG Cancer Research Network” page (read 2026-11-07) describes three programs:
| Program | Who it is for, per SWOG | Funding condition stated |
|---|---|---|
| Member Institution Program | Active NCI Lead Academic Participating Sites (LAPS) and clinical institutions able to enroll many patients in SWOG treatment trials, with extensive clinical research staff expertise | Members are funded through the NCI’s NCTN |
| NCORP Member Program | Community hospitals that want to take part in SWOG cancer control, delivery, prevention and treatment trials under NCORP | “SWOG NCORP members must maintain NCORP funding” |
| Affiliate Program | Smaller community hospitals or private practices that work with a member institution acting as sponsor | Affiliates have access to almost all SWOG treatment and prevention trials |
NCORP is managed by the NCI’s Community Oncology and Prevention Trials Research Group, according to the same page.
What membership involves and how to apply
SWOG’s page publishes no application checklist or fee schedule. It states: “For application information, contact [email protected].” The practical sequence for an administrator, which is editorial interpretation drawn from the program descriptions above, is:
- Work out which program matches the institution: LAPS or NCTN-funded academic site, NCORP-funded community site, or a smaller site that has a member institution willing to sponsor it.
- Confirm the funding status the program names (NCTN funding for member institutions, current NCORP funding for NCORP members).
- Contact SWOG’s membership address for the application details, since none are published on the page.
Federal cooperative agreement terms that sit behind NCI network funding are explained in the entry on the U01 NIH cooperative agreement. Trial costs billed to Medicare are governed separately; see Medicare clinical trial policy (NCD 310.1).
Typical phases from interest to participation
SWOG does not publish durations, so none are given here. The order of phases implied by its program descriptions is: program selection, confirmation of funding status, contact with the membership office, and then access to the trials the program covers. Timing depends on the institution and on SWOG’s own process.
Common mistakes
- Treating SWOG as part of the NCI rather than a group within the NCTN. The NCI lists SWOG alongside the other NCTN groups shown in the table above; each coordinates its own trials.
- Assuming NCORP membership continues without NCORP funding. SWOG states members must maintain it.
- Assuming a small site can join alone. The Affiliate Program is described as operating with a member institution as sponsor.
- Using an old name. Southwest Oncology Group appears in older literature; the current name is SWOG Cancer Research Network (since 2018, per SWOG).

FAQ
Where is SWOG in 2026?
SWOG is a network, not a single site: it lists members in 46 US states and 8 other countries. Its join page publishes no street address or headquarters location, only the membership email [email protected]; general contact details are on SWOG’s contact page.
Is SWOG the same as the NCI?
No. The NCI funds the NCTN; SWOG is one of the groups within it.
How do donations to SWOG work?
SWOG’s home page directs donations to The Hope Foundation for Cancer Research, which it describes as a public charity.
