Where anaplastic thyroid cancer treatment is heading

Anaplastic thyroid cancer · Updated Nov 12, 2026

Anaplastic thyroid cancer is rare, affecting roughly 1,000 to 1,500 people a year in the US, and grows fast. Survival used to be measured in months. Gene testing, targeted pills and immunotherapy have extended it, especially for tumors with a BRAF change.

  1. Now

    Nov 2026

    BRAF pills shrink most BRAF tumorsHappened 68% tumors shrank on BRAF pills

    Dabrafenib with trametinib is approved for anaplastic thyroid cancer with the BRAF V600E change.

    68%: had their tumors shrink on BRAF and MEK pills.

    Matched drugs plus immunotherapyHappened 19 months median survival

    A trial matching drugs to each tumor's gene change, plus atezolizumab, reached a median survival of 19 months.

    19: months median survival, against about 5 months historically.

    An option without the BRAF changeHappened 13 months median survival

    Lenvatinib with pembrolizumab gave a median of 13 months in tumors without BRAF.

    13: months median survival without the BRAF change, against about 3 months historically.

  2. 6 months

    by May 2027

    Targeted pills before surgeryPossible

    A Dutch trial gives dabrafenib and trametinib before and after surgery for BRAF tumors. Due January 2027.

  3. 12 months

    by Nov 2027

    Three-drug combinations reportPossible

    Small trials add an immunotherapy to BRAF and MEK pills, at Memorial Sloan Kettering and MD Anderson.

    A new MEK drug enters testingPossible

    A company plans a potentially registration-level trial of atebimetinib with chemotherapy, applying to start by end of 2026.

  4. 3 years

    by late 2029

    Immunotherapy plus targeted drugs before surgeryPossible 68% tumors shrank on BRAF pills

    An MD Anderson trial tests pembrolizumab with BRAF and MEK pills before surgery. It finishes in 2028.

    68%: had their tumors shrink on BRAF and MEK pills.

    UK gene-matched trials reportLong shot

    Two arms of the UK DETERMINE program test BRAF-MEK combinations in rare cancers, including this one.

  5. 5 years

    by late 2031

    Immunotherapy after surgery tested properlyLong shot

    A randomized trial could confirm the early signal from giving pembrolizumab after surgery and radiation.

    Long-term survival for more peopleLong shot 19 months median survival

    Combining gene-matched drugs with immunotherapy before surgery could make long-term survival common for BRAF tumors.

    19: months median survival, against about 5 months historically.

The research paths

Maturing

Gene-matched pills

68% tumors shrank on BRAF pills
Details and 3 trialsHide

About 45% of tumors carry the BRAF V600E change, and BRAF plus MEK pills shrink most of them. Giving them before surgery looks especially promising.

WatchTrials of these pills before surgery.

Heating up

Adding immunotherapy

19 months median survival
Details and 3 trialsHide

Combining immunotherapy with targeted drugs has produced survival measured in years for some people. All results so far are from small trials without comparison groups.

WatchAny randomized trial.

Early

Tumors without a target

13 months median survival
Details and 1 trialsHide

About 60% of tumors lack the BRAF change. Lenvatinib with pembrolizumab and antibody-drug conjugates are being tried.

WatchThe sacituzumab govitecan trial.

Borrowed from other cancers

From Melanoma

Dabrafenib and trametinib

68% tumors shrank on BRAF pills Approved

BRAF and MEK pills developed for melanoma with the same BRAF change.

From Endometrial and kidney cancer

Lenvatinib and pembrolizumab

13 months median survival Phase 2

A pairing approved in other cancers, tested here for tumors without BRAF.

From Breast cancer

Sacituzumab govitecan

Phase 2

An antibody that carries chemotherapy into cells, tested in aggressive thyroid cancers.
