Background: The increasing incidence of breast cancer is paralleled by an increasing demand for post-mastectomy breast reconstruction. At the time of breast reconstruction routine submission of mastectomy scars has been considered appropriate clinical practice to ensure that no residual cancer exists. However, this practice has been challenged by some and has become the topic of controversy. In a retrospective analysis we wished to assess whether routine submission of mastectomy scars altered treatment.
Methods: Utilizing the Stanford Translational Research Integrated Database Environment (STRIDE) all patients who underwent implant-based breast reconstruction with routine histological analysis of mastectomy scars were identified. The following parameters were retrieved and analyzed: age, cancer histology, cancer stage (according to the American Joint Committee on Cancer staging system), receptor status (estrogen receptor [ER], progesterone receptor [PR], Her2neu), time interval between mastectomy and reconstruction, and scar histology.
Results: A total of 442 patients with a mean age of 45.9 years (range, 22-73 years) were included in the study. Mastectomy with subsequent reconstruction was performed for in-situ disease and invasive cancer in 83 and 359 patients, respectively. A total of 619 clinically unremarkable mastectomy scars were sent for histological analysis, with the most common finding being unremarkable scar tissue (i.e. collagen fibers). Of note, no specimen revealed the presence of carcinoma.
Conclusion: According to published reports routine histological examination of mastectomy scars may detect early local recurrence. However, we were not able to detect this benefit in our patient population. As such, particularly in the current health-care climate the cost-effectiveness of this practice deserves further attention. A more selective use of histological analysis of mastectomy scars in patients with tumors that display poor prognostic indicators may be a more reasonable utilization of resources.

Background: Breast cancer is the most common cancer among women. The number of cases is increasing among young women, and consequently, breast reconstructions are performed more often. Postoperative complications, wound healing, and the quality of scars influence the final cosmetic outcomes.

Article Synopsis
- Laparoscopically Harvested Pedicled Omental Flap (LHPOF) is becoming a popular method for breast reconstruction due to its minimally invasive nature, leading to less pain and scarring post-surgery.
- A study analyzed imaging results from eight patients who had LHPOF for breast reconstruction, showing changes like fat replacing glandular tissue and the presence of internal vessels; one case of cancer recurrence was found.
- The findings highlight the importance of monitoring imaging results for patients with omental flap reconstruction to catch potential recurrences effectively.

Background: Two-stage prosthetic breast reconstruction involves the exchange of tissue expanders for implants, but complications of this procedure can necessitate revision surgeries and implant removal. The choice between remote incision (RI) and traditional access via existing mastectomy scars (MS) for this exchange remains underexplored. RIs offer potential benefits by placing the incision at a region of higher quality tissue, prompting our comparative analysis of complications between RI and MS.
