Patients' view on intraoperative diagnosis of sentinel nodes in breast cancer: Is it an automatic choice?

Abstract

Intraoperative detection of sentinel node metastases in breast cancer enables immediate axillary lymph node dissection. This approach, however, introduces uncertainty for patients as to the extent of surgery. Waking to find a surgical drain implies more extensive surgery and worse prognosis disease. False negative diagnoses may cause disappointment. Aim To evaluate patients' views and preferences on intraoperative diagnosis of sentinel nodes in breast cancer. Methods Questionnaire based survey of 100 patients who had previously undergone sentinel node biopsy with intraoperative diagnosis using touch imprint cytology (TIC). Patients were encouraged to add free text comments. Results Sixty-four patients responded to the questionnaire. Patients rated the information provided and their understanding of the procedure highly. Fifty-nine percent of respondents overestimated the sensitivity of TIC. Ninety-five percent of patients would choose to undergo intraoperative diagnosis in future if required. Five percent of patients would choose not to undergo intraoperative diagnosis, citing the resultant uncertainty, disappointment on waking and needing time to come in terms with the diagnosis of metastases as reasons. Conclusion Given the choice, most patients would choose intraoperative diagnosis, though a minority would explicitly not, due to the adverse psychological effect thereof. Despite a good understanding of the procedure, the majority of patients overestimate the sensitivity of intraoperative diagnosis of sentinel nodes, which may heighten disappointment when a false negative diagnosis occurs. Intraoperative diagnosis should not be the automatic choice and patients should be actively involved in this decision making process.
