Design: Non-randomized study evaluating hydrogel application feasibility, post-operative hydrogel imaging characteristics, cavity healing following hydrogel absorption and the resulting breast cosmesis. Setting: Teaching hospital University of Essen, Germany. Patients: Seven (7) patients underwent unilateral or bilateral breast conservation surgery to remove cancerous or benign tumors. Interventions: All patients received hydrogel application following primary tumor excision. Imaging performed in the first postoperative week included ultrasound, MRI and CT. Breast cosmesis scores were obtained at one and three months following surgery. Measurements and Main Results: While preliminary, a relationship between percent cavity filling and drainage was observed, with 30% or more cavity filling resulting in decreased drainage. Additionally, the hydrogel was readily visible under ultrasound, MRI and CT imaging modalities. Finally, patients were satisfied and surgeons felt that patient cosmesis was improved relative to their prior experience. Conclusion: Initial data suggest that hydrogel filling may reduce excision cavity drainage, which may reduce seroma or hematoma formation. Additionally, these gels may improve cavity visibility and stability, furthering the use of partial breast irradiation. Finally, while more studies are required, these materials may have a role in improving long term patient cosmesis.展开更多

Breast cancer incidence increases annually due to the aid of established screening programs, leading to the discovery of breast cancer in its early stages. Surgical treatment is an integral part of early breast cancer management to achieve local control. Axillary surgical interventions such sentinel lymph node biopsy (SLNB) and axillary lymph node clearance (ALND) aim to stage the axilla as an adjunct to the management of the primary breast tumor. In this paper, we reviewed female breast cancer patients aged 30 - 60 who underwent surgical treatment of SLNB and/or ALND with reporting the prevalence of lymphedema and other associated complications and risk factors. Methodology: A cross-sectional non-interventional study, with a sample size of 250 including breast cancer cases from 2016 to 2019 at National Guard Hospital (NGH) in Jeddah, Saudi Arabia. Results: A total of 253 breast cancer cases were included in this study, with a mean age of 53 years, 52.7% were postmenopausal and positive family history was present among 21% of cases. Further, 90.9% of the cases had unilateral disease. Staging was as follows: stage I 14.5%, stage II 45.2%, stage III 37.1%, and stage IV 3.2%. Mastectomy was done in 73.4% cases and lumpectomy was performed in 34.1% of cases. In addition, 93.3% of patients had SLNB and 49% of them were positive. Axillary dissection was performed in 69.6% of our patients. Radiotherapy and chemotherapy were given to 71.8% and 80.4% of cases respectively. Among the chemotherapy (chemo) recipients, 40.2% received adjuvant chemo, 54.5% received neoadjuvant chemo, and the remaining 5.3% received both. Further, the most prevalent complication was pain accounting for 42.1% of total complications, and the least prevalent was cellulitis 4%. Also, seroma developed in 18.3% cases, paresthesia noted in 5.6% of cases, winged scapula was reported as 2%, weakness and necrosis were seen in 6% and 13.1展开更多

Methods: A retrospective study of frozen section of lumpectomy margins of one hundred ten patients was done at King Abdulaziz University Hospital from June 2007 to June 2013. All patients underwent lumpectomy + Sentinel lymph node biopsy. Patient records were studied for location of mass in breast, size of mass, site of breast, pre or postmenopausal, frozen section margins, new frozen section margins, permanent margins, reoperation. Complications like skin necrosis, numbness, and wound infection were studied. Result: Majority were Saudis (64.5%). Left breast was involved in 60%. Upper outer quadrant was involved in majority (51.9%). Size of mass was less than 1 cm in 14.8% cases, 1 - 2.9 cm in 43.5%, 3 - 4 cm in 13%, more than 4 cm in 10.2%. Lumpectomy plus sentinel lymph node biopsy was done in 96.4% and lumpectomy and axillary lymph node dissection was done in 1.8% cases. Gross margins were positive in 17.3% and frozen margins were positive in 28.2%. New margin on frozen section were positive in 3.6% and negative in 79.1%. Permanent section histology showed positive margins in 5.5% and negative in 94.5% cases. Re-operation was done in 7.3%. Lympho-vascular margins were positive in 20.9%. Skin necrosis was found in 2.2%, numbness was found in 4.4%, wound infection was in 2.2%. Conclusion: Lumpectomy margins with frozen section reduce re-operation and recurrence.展开更多

Oncoplastic resection also entails a contralateral procedure for symmetry and the potential benefit of a superior cosmetic outcome. Our aim was to examine the cost-effectiveness of this treatment strategy comparing it to standard lumpectomy in treating breast cancer patients. Methods: A literature review was performed of the probabilities and outcomes related to treatment of unilateral breast cancer via oncoplastic resection or unilateral lumpectomy. Utility score surveys were used to estimate the quality adjusted life years (QALYs) associated with a successful procedure, additional margins excision and post-operative complications. A decision analysis tree was developed to highlight the more cost-effective strategy. An Incremental Cost-Utility Ratio (ICUR) was calculated. Sensitivity analysis was performed to check the robustness of our data. Results: Oncoplastic resection was associated with fewer positive margins relative to standard lumpectomy (10.0% versus 18%). In cases with positive margins, a greater percentage of oncoplastic resection patients chose a mastectomy compared to the lumpectomy patients (72% versus 19%). Utility scores for a successful operation favored oncoplastic resection (92.6 versus 86.55), but in instances of positive margins, favored the lumpectomy patients (74.2 versus 70.2). Decision tree analysis revealed that oncoplastic resection was more cost-effective with an ICUR of $2609.66/QALY gained. Conclusion: Oncoplastic resection represents a cost-effective strategy for the large breasted patient and provides the surgical team yet another reasonable option for the appropriate patient.展开更多

In this study, we attempted to determine whether the DML technique could be useful for other types of breast surgery, in addition to breast cancer lumpectomy. Methods: This study examined a total of 4 patients who underwent the DML technique and were followed up for at least 1 year postoperatively. One patient underwent phyllodes tumor resection, 1 patient underwent removal of a siliconoma, and 2 patients underwent breast reduction mammaplasty. Results: This method enabled en-bloc removal of a large tissue mass or large foreign body that could not be removed through a short periareolar incision. The surgical method of this study enabled the extent of de-epithelialization to be changed according to the size and location of the mass to be excised;good cosmetic results were also obtained. In addition, the surgical method enabled the facile excision of tumors and foreign materials. Conclusions: The DML technique is a useful surgical method that is applicable to other breast surgeries, in addition to breast cancer surgery.展开更多
