Twenty‐nine patients, who each received modified radical mastectomy, were recruited for this study. Wounds were inspected daily for the presence of flap necrosis, infection, and seroma. Drain fluid (20 ml) was collected at 6 a.m. on postoperative days 1, 2, and 5 and the levels of interleukin (IL)‐4, IL‐6, tumor necrosis factor‐α, and interferon‐γ determined. For patients with no wound events, only IL‐6 levels were elevated during the initial phase, but in the later phase the IL‐6 levels dropped with a corresponding rise in tumor necrosis factor‐α levels. In patients with flap necrosis, there was a sequential rise of IL‐4 on day 1, IL‐6 on day 2, and tumor necrosis factor‐α on day 5, but only IL‐4 was found to be a statistically significant factor associated with necrosis. In patients with seroma, the levels of IL‐4 and interferon‐γ were persistently low and were both statistically significant. To conclude, IL‐6 and tumor necrosis factor‐α are important in normal postoperative wound healing and IL‐4 and interferon‐γ may be associated with postoperative necrosis and seroma.
