Median time to pemetrexed initiation was 73 months. Partial response (PR) was observed in 6\/22 (27%) of all patients and in 5\/11 (45%) with non-ATC. Median progression-free survival was 148 days for all tumors and 375 days for patients with non-ATC. One patient with ATC remains on pemetrexed\/carboplatin with a PR to therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Pemetrexed single agent or in combination with carboplatin has comparable efficacy to approved second-line therapies for advanced thyroid cancer.
