Breast cancer recurrence after reoperation for surgical bleeding

Area of Science:

• Oncology
• Surgical Oncology
• Cancer Metastasis

Background:

• Platelet activation by bleeding may promote tumor cell binding and metastasis.
• Postoperative bleeding and subsequent reoperation are potential complications after cancer surgery.
• The relationship between reoperation for bleeding and breast cancer recurrence remains unclear.

Purpose of the Study:

• To investigate the association between reoperation for postoperative bleeding and breast cancer recurrence.
• To determine if surgical intervention for bleeding impacts long-term cancer outcomes.
• To analyze recurrence rates based on the need for reoperation.

Main Methods:

• A large cohort of women with stage I-III breast cancer undergoing surgery (1996-2008) was identified using Danish national registries.
• Data on reoperation for bleeding within 14 days of primary surgery were extracted.
• Cox regression models analyzed the association between reoperation and breast cancer recurrence, adjusting for confounders, with follow-up until 2013.

Main Results:

• The study included 30,711 patients with 205,926 person-years of follow-up.
• 767 patients (2.5%) required reoperation for bleeding within 14 days of primary surgery.
• No significant association was found between reoperation for bleeding and breast cancer recurrence (adjusted hazard ratio: 1.06; 95% CI: 0.89–1.26).

Conclusions:

• This large cohort study found no evidence linking reoperation for postoperative bleeding to an increased risk of breast cancer recurrence.
• The findings suggest that surgical intervention for bleeding complications does not negatively impact breast cancer outcomes.
• Patients undergoing reoperation for bleeding can be reassured regarding their breast cancer recurrence risk.
