Background:
The routine use of drainage after axillary node dissection in patients undergoing breast-conserving therapy (BCT) is being questioned. To determine the value of routine drainage, we evaluated the postoperative course of patients with primary breast carcinoma who underwent axillary dissection with or without axillary drainage.
Methods:
A retrospective review of 69 patients prompted a prospective randomized trial of 46 patients undergoing BCT at our tertiary cancer center. Variables studied were age, treatment (drain or no drain), number and tumor status of excised lymph nodes, size of primary tumor, duration of drainage or aspiration, number and volume of aspirations, number of office visits, incidence of complications and degree of pain, change in arm or forearm circumference, and body mass index (BMI). Data from prospective and retrospective studies were pooled for analysis.
Results:
Of 115 patients, 72 were treated with a drain (Drain group) and 43 were not (No-drain group). Overall there was no difference in the number or tumor status of excised nodes, the size of the primary tumor, or the incidence of complications between the two groups. Aspiration was required in 50% of the No-drain patients and 8.3% of the Drain patients. The incidence of drain placement or replacement postoperatively was 9.3% for the No-drain patients and 4.2% for the Drain patients. The No-drain patients had more office visits (5.1 +/- 0.4 vs. 3.6 +/- 0.1; P = .0002) and a longer interval between operation and last aspiration or drain removal (16.2 +/- 1.4 days vs. 11.3 +/- 0.6 days; P = .0040). Findings were similar in the subgroup of 46 prospectively studied patients, who included 24 Drain patients and 22 No-drain patients. In this group, pain evaluation using a scale of 0 to 10 showed a mean rating of 4.2 +/- 2.6 in Drain patients and 2.7 +/- 0.4 in No-drain patients (P = .0062).
Conclusions:
Axillary node dissection can be managed with or without a drain. More office visits but less pain can be expected if a drain is not used.
