In the Anaplastic Thyroid Cancer segmentation by type, the market is split between monotherapy and combination therapy. Monotherapyโdominated by single-agent cytotoxics such as weekly paclitaxelโaccounts for the larger share because it offers rapid access in resource-constrained centres and forms the comparator arm in pivotal registrational trials. Combination therapy, while smaller, is expanding fastest; regimens coupling BRAF/MEK inhibitors with checkpoint blockade are being adopted in tertiary centres where genomic profiling is routine. The relative value contribution of each type is driven less by price differential and more by duration of treatment: combination protocols extend median cycles from 4โ6 (monotherapy) to 10โ12, effectively doubling per-patient revenue. Consequently, although monotherapy holds 58 % of incident lines, combination therapy generates 52 % of 2023 market value, illustrating how treatment intensity converts clinical share into economic share in this market taxonomy.
