Purpose:
Radiotherapy (RT) is an integral component in the treatment of breast cancer. The aims of this study were to estimate the cost per 5-year Local Control (LC) and Overall Survival (OS) benefits of the first course of RT, based on breast cancer stage, and the potential cost savings with adoption of the FAST-Forward protocol.
Methods And Materials:
All RT activities for breast cancer RT July 2017-June 2020 and their associated costs were consolidated together. The average cost of treatment course was calculated (average cost per fraction X average no. of fractions). Cost per outcome was estimated based on published gains in 5-year LC and OS with optimal use of radiotherapy.
Results:
481 patients with breast cancer were analysed. The average cost per fraction was $285 AUD (£148 GBP) for all stages. The average costs for 5-year LC and OS gain were $31,483 AUD (£16 392 GBP) and $235,435 AUD (£122 566 GBP) respectively for all stages. The estimated costs for 5-year LC outcomes were $29,675 AUD (£15 450 GBP), $34,675 AUD (£18 053 GBP) and $32,478 AUD (£16 910 GBP) for Stage I-III respectively. The estimated costs for 5-year OS were $455,909 AUD (£237 378 GBP), $532,727 AUD (£ 277 375 GBP) and $60,717 AUD (£31 614 GBP) for Stage I-III respectively. 266 patients had characteristics that made them eligible for the FAST-Forward protocol. A cost saving of $2592-3864 AUD (£1350-2012 GBP) per patient was estimated had these patients been treated with the protocol.
Conclusions:
The cost of RT for LC outcome is similar across stages. The greatest value for OS outcome was seen in patients with Stage III breast cancer, due to the greater survival benefit with RT in these patients compared with Stage I-II breast cancer. Significant cost savings can be made by implementing the FAST-Forward protocol.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
