HealiAid Collagen Wound Dressing in Patients Undergoing Breast Tumor Surgery

This study is an open label, multicenter post-market clinical follow-up study with a single arm group design. Included patients with confirmed diagnosis of breast tumor who are candidates for surgical treatment, including breast partial mastectomy (BPM), breast conserving surgery (BCS), sentinel lymph node dissection (SLND) and/or axillary lymph node dissection (ALND). Within the surgery procedure, the tumor is completely removed with a margin of 1-2 cm around healthy tissue. Wounds are then cleaned properly before applying the HealiAid Collagen Wound Dressing. HealiAid is soft and pliable. It can be adjusted to the size of the wound, and it is recommended to apply one to four pieces per wound. HealiAid Collagen Wound Dressing will be kept in place until absorbed completely. The rehabilitation and the related introduction postoperative will follow the hospital protocols, patients will be advised to mobilize the ipsilateral arm within a few hours after surgery. Patients will be visited at weeks 1, 2, 4, 12, 26, and 52 after surgery and assessed for surgical site wound and AE assessment. Additionally, photographs of the breast appearance are taken post-surgery before discharge and at weeks 12, and 52 after the surgery. Patient's quality of life (QoL) and satisfaction are evaluated using the Breast-Q questionnaire on screening day, before surgery on day 1, and at weeks 2, 12, 26, and 52 after the surgery. Vital signs including respiratory rate, pulse, blood pressure and temperature will be continuously measured during the patients' hospitalization period following the surgery, which is estimated to last up to 3 days. For the follow up examination, the breast ultrasonography will be performed at week 2 and 26 and week 52, and mammography will be performed at week 52. The hematology test and Tumor marker test will be performed at week 26. All hypothesis tests are two-sided, use α=0.05, if P\<0.05, it is considered statistically significant. For inferential statistics, comparison of quantitative data, use the t-test or Wilcoxon rank sum test. For count data comparison, use Chi-square test or Fisher's exact test. For continuous data comparison, use repeated measured ANOVA test. For main/significant safety indicators, consider the influence of center or other stratification factors and perform Pearson correlation test (with baseline data as covariates).
