Shared Decision-Making and Short-Course Radiotherapy for Operable Rectal Adenocarcinoma: A Patient's Right to Choose

As new treatment options for colorectal cancer (CRC) emerge, physicians and WOC nurses must be prepared to assist patients to choose care that meets their needs and preferences. A patient with T2N0M0 rectal adenocarcinoma was offered the US current standard of practice; he was not offered alternative treatment options. This case study emphasizes the need to ensure patients are offered all reasonable options for treatment. Shared decision-making is a process that helps patients actively participate in their heath choices rather than exclusively relying on the judgment of a health care provider.

Mr J was a 70-year-old man with operable CRC who sought care at a health care facility in his community. He was offered a single option, based on standard of care for this tumor stage: long-course neoadjuvant chemoradiotherapy followed by surgery and additional chemotherapy. After seeking a second opinion at a cancer care center in another state, Mr J chose to undergo a viable alternative treatment option (short-course radiotherapy, followed by surgery, with chemotherapy contingent on his nodal status post-surgery). No nodal involvement was found post- surgery (T2N0M0) enabling him to avoid postoperative chemotherapy.

This case illustrates the need for all health care providers and carers to regularly engage in shared decision-making when choosing among treatment options. In this case, short-course radiotherapy offered Mr J a shorter duration of treatment and avoided the risk for adverse side effects associated with chemotherapy, resulting in improved health-related quality of life. Initial omission to disclose all treatment options to Mr J may have reflected the preferences of the surgeon, institutional financial pressures, or discomfort with shared decision-making, but it failed to provide him with full range of options, given his diagnosis and tumor stage. All members of the patient's care team, including the WOC nurse, play a pivotal role in ensuring transparency in medical care, including advocating for shared decision-making where patients are made aware of all viable treatments, followed by supporting the patient as they reach a decision.
