Patient and physician preferences for surgical and adjuvant treatment options for rectal cancer

Hypothesis: Patients and their clinicians hold varying preferences for surgical and adjuvant treatment therapies for rectal cancer. Design: Preferences were determined using the Prospective Measure of Preference. Setting: Royal Prince Alfred and St Vincent's hospitals in Sydney, Australia. Participants: Patients with colorectal cancer were interviewed during their postoperative hospital stay, and physicians were asked to complete a mailed survey. Main Outcome Measures: The Prospective Measure of Preference method produces 2 outcome measures of preference: willingness to trade and prospective measure of preference time trade-off. Results: Patients' strongest preference was to avoid a stoma: more than 60% would give up a mean of 34% of their life expectancy to avoid this surgical option. This was followed by treatment options involving chemoradiotherapy, where more than 50% would give up a mean of almost 25% of their life to avoid treatment. Surgeons held stronger preferences against all adjuvant options compared with oncologists (P <=.01). Conclusions: Patients had strong preferences against all treatment options, and these preferences frequently differed from those of physicians. These results highlight the importance of determining patients' own preferences in the clinical encounter. Furthermore, the diversity of preferences of clinical subspecialists emphasizes the need for multidisciplinary treatment planning to ensure a balanced approach to treatment decision making for patients with rectal cancer.
