Active Participation in Decision-Making in Contralateral Prophylactic Mastectomy for Patients With Breast Cancer.

BACKGROUND

We sought to determine how patient-physician communication affects patients' decision-making when choosing between contralateral prophylactic mastectomy (CPM) and unilateral mastectomy (UM).

METHODS

atients with breast cancer who underwent mastectomy at our institution were approached with a survey regarding patient-physician communication in CPM.

RESULTS

Of 101 patients who completed the survey, 55 underwent CPM (54.5%). Thirty-three patients (33%) stated that their physician recommended UM, six (6%) stated their physician recommended CPM, and 61 (61%) stated they engaged in active participation in decision-making. Most patients whose doctors recommended UM chose UM (78.8%); similarly, 83.3% of those whose doctors recommended CPM chose CPM. Of 39 patients whose doctors recommended a particular surgical option, eight (20.5%) did not follow their doctor's advice. These patients were equally as satisfied with their decisions as those who followed their doctor's advice (P = 0.441). Patients engaging in active participation in decision-making tended to choose CPM (68.3% versus 30.8%, P < 0.001). Patients who did not engage in active participation were similarly satisfied with their decision as those who did (P = 0.286). Twelve patients (12%) stated they preferred their doctor to provide a recommendation, seven (7%) preferred to make the decision on their own, and 81 (81%) preferred to actively participate in their decision-making with the physician.

CONCLUSIONS

Patients tend to follow physicians' recommendation of UM or CPM; patients engaging in SDM tend to choose CPM. Most patients prefer to engage in active participation in decision-making with their physician but were equally satisfied with their surgical decision whether they engaged in active participation or not.
