Abstract
Purpose: Prior studies have documented variation in breast cancer treatment and care that does not follow guideline recommendations, particularly for elderly women. We assessed whether consultation with a medical oncologist before surgery was associated with use of definitive surgery, axillary node dissection, and type of surgery. Methods: We conducted a retrospective cohort study of a population-based sample of 9,630 women aged ≥ 66 years diagnosed with breast cancer during 1995 to 1996. We measured the adjusted proportion visiting a medical oncologist before surgery, identified factors associated with such visits, and assessed the association between visits with a medical oncologist and use of definitive surgery (mastectomy or breast-conserving surgery with radiation v breast-conserving surgery without radiation); axillary dissection; and breast-conserving surgery versus mastectomy among women undergoing definitive surgery. Results: Nineteen percent of women visited a medical oncologist before surgery; these women were younger, more often had larger or more poorly differentiated cancers, had more comorbid illnesses, and were treated more often at a teaching hospital (all P < .05). Women who saw a medical oncologist before surgery were more likely than others to undergo definitive surgery (adjusted odds ratio [OR], 1.28; 95% CI, 1.05 to 1.56) and axillary dissection (adjusted OR, 1.44; 95% CI, 1.19 to 1.73), but less likely to undergo breast-conserving surgery among women undergoing definitive surgery (OR, 0.84; 95% CI, 0.75 to 0.95). Conclusion: Elderly women who consulted with a medical oncologist before surgery were more likely to receive guideline-recommended care. Additional research is needed allow a better understanding of the quality and content of discussions that elderly women have with various providers about breast-conserving surgery and mastectomy.
