Combined Endoscopy-Assisted Muscle-Sparing Latissimus Dorsi Flap Harvesting with Lipofilling Enhancement as a New Volume Replacement Technique in Breast Reconstruction.

Introduction: This study evaluated the feasibility and patient satisfaction of combined endoscopy-assisted muscle-sparing latissimus dorsi flap harvesting, with lipofilling enhancement for skin-preserving mastectomy. Methods: This is a prospective study that included 21 female patients with small breasts (cup size A-B), subjected to skin-preserving mastectomy as a management of breast cancer. Combined endoscopy-assisted muscle-sparing latissimus dorsi flap harvesting with lipofilling enhancement was performed for immediate breast reconstruction. Patients were followed up for early and late postoperative complications including recurrence for at least 24 months. Postoperative patient satisfaction was assessed using the Kyungpook National University Hospital breast reconstruction satisfaction questionnaire. Results: The study included 21 female patients with a mean age of 42.10 ± 8.46 years. Patients were followed up for 26.67 ± 3.38 months. The procedure was successful in all patients with a mean duration of 172.05 ± 28.22 minutes. Local recurrence was encountered in one patient (4.67%). Eighteen patients declared their satisfaction 6 months after the operation, while two patients were satisfied only after the second session of lipofilling. The overall postoperative patient satisfaction was 95.24%. The majority of the patients (93.3%) who underwent NSM surgery were satisfied, while only two-thirds (66.6%) of the patients who underwent SSM surgery were satisfied. Conclusions: Combined endoscopy-assisted muscle-sparing latissimus dorsi flap harvesting with lipofilling enhancement seems to be a feasible and encouraging technique for the volume adjustment of small breasts, especially in nipple-sparing mastectomy. It leaves a minor back scar and has an acceptable rate of postoperative complications. The procedure showed high postoperative patient satisfaction.

Immediate Lipo-Filling as a Novel Technique for Volume Replacement in Oncoplastic Breast Conservative Surgery.

BACKGROUND: We aimed to evaluate the feasibility of immediate lipofilling as a volume replacement technique in breast conservative surgery (BCS) in terms of the volume of fat graft resorption after radiotherapy, patient satisfaction, and oncological safety. PATIENTS AND METHODS: This was a prospective study that included female patients with breast cancer, with small- or medium-sized breasts. The patients underwent BCS followed by lipofilling into the deformed areas away from the tumor site that resulted from direct closure of the tumor cavity. They were followed up for early and late postoperative complications, including recurrence. Volumetric computed tomography was performed before and after radiotherapy to determine percentage fat resorption. Postoperative patient satisfaction was assessed using the Kyungpook National University Hospital Breast Reconstruction Satisfaction Questionnaire. RESULTS: The study included 54 female patients with a mean age of 47.57 ± 9.26 years. The mean follow-up period was 31.02 ± 4.47 months. Local recurrence was observed in three patients (5.56%). The volume reduction of the injected fat graft ranged from 10.15% to 55.67%, with a mean of 29.27 ± 10.06%. Fifty-two patients (96.30%) reported postoperative satisfaction, and nine of them expressed satisfaction only after a second lipofilling session. CONCLUSIONS: Immediate lipofilling as a volume replacement technique in BCS is a safe and simple technique without major complications. It has a locoregional recurrence rate similar to BCS alone, with an acceptable fat resorption percentage and high postoperative patient satisfaction.

A new oncoplastic technique for removal of centrally located malignant tumors and reconstruction by a local dermo-glandular flap in conservative breast surgery.

AIM: To evaluate the local dermo-glandular flap as a new reconstructive oncoplastic technique after removal of central malignant tumors of the breast, in terms of patient satisfaction and local recurrence. PATIENTS AND METHODS: This study included 60 females with centrally located breast cancer who underwent central quadrantectomy and local dermo-glandular flap with either sentinel lymph node biopsy or axillary clearance. RESULTS: The mean age of the patients was 49.68 ± 8.52 years. The duration of the operation ranged from 68-105 minutes, with a mean of 79.77 ± 9.41 minutes. Local recurrence was observed in three patients (5.00%) with no distant metastasis. Forty-seven patients (78.33%) reported satisfaction after the operation. Ugly scarring and the existence of tissue defects were the main factors affecting patient satisfaction. Correction of these complications increased overall satisfaction to 88.33%. CONCLUSIONS: For small- and medium-sized breasts, the use of a local dermo-glandular flap for the management of centrally located malignant tumors seems to be a simple and easy technique with good oncological outcomes and acceptable few minor complications. This technique offers an immediate reconstruction of a new areola with fewer scars that will be hidden later after areola tattooing. Most of the patients reported satisfaction three months after areola reconstruction.

Evaluation of serum Nestin and HOTAIR rs12826786 C>T polymorphism as screening tools for breast cancer in Egyptian women.

BACKGROUND: Nestin is a neural stem cell protein that plays an important role in cancer stem cells (CSC) development and proliferation. It has been identified as a marker for newly formed endothelial cells and was shown to be preferentially expressed in basal and myoepithelial cells of the mammary gland. HOTAIR is long intergenic non-coding (linRNA) associated with tumorigenesis through promotion of epithelial-mesenchymal transition (EMT) and stemness as well. HOTAIR gene contains a functioning single nucleotide polymorphic site rs12826786 C>T that has been associated with several cancer types. METHODS: We evaluated serum Nestin and the HOTAIR rs12826786 C>T polymorphism in healthy Egyptian women and those with breast cancer as a possible screening tool to identify patients with breast cancer. Also, we tested the possible association of the two markers with each other and the aggressiveness of the disease. RESULTS: Patients with breast cancer had a median (Min-Max) of serum Nestin 31.3 (6.7-167.3 pg/mL), while control subjects had a median (Min-Max) of serum Nestin 42.3 (25.7-315.95) pg/mL. The best cut-off value for serum Nestin to differentiate normal subjects and patients with breast cancer was 39.9 pg/mL. This cut-off value had a diagnostic sensitivity of 84.8% and specificity of 65.1%. There was a significant difference in the distribution of different alleles in patients with breast cancer than normal subjects (P=0.039 Exact Fisher test). The breast cancer patients group had 23.9% CC, 52.1% CT, and 23.9% TT genotypes, respectively, while the control group had 46.9% CC, 42.8% CT, and 10.2% TT, respectively. CONCLUSIONS: A significantly low serum Nestin below 39.9 pg/mL and a higher percentage of the T/T homozygous variant allele of HOTAIR rs12826786 C>T were found in Egyptian patients with breast cancer. We suggest that the reported cut-off value of serum Nestin and the presence of C/T polymorphism can be used to assess the risk of females for developing breast cancer and might be of potential benefit in screening the disease. Larger studies in different ethnic groups are needed to confirm our findings.

Latissimus Dorsi flap enhancement by lipofilling as an immediate breast reconstruction technique for skin-preserving mastectomy.

AIM: To evaluate Latissimus Dorsi flap (LD) enhancement by lipofilling as an immediate breast reconstruction technique, for skin-preserving mastectomy regarding oncological safety, fat graft resorption after radiotherapy, and patients' satisfaction. PATIENTS AND METHODS: This is a prospective study that included female patients complaining of breast cancer. Patients were subjected to skin-preserving mastectomy associated with Latissimus Dorsi flap enhancement by lipofilling using the multisite, and multilayer fat grafting technique of injection. Patients were followed up for early and late postoperative complications including recurrence. Volumetric CT was performed before and after the radiotherapy to detect the percentage of fat resorption. Postoperative patients' satisfaction was assessed using the Kyungpook National University Hospital (KNUH) Breast Reconstruction Satisfaction Questionnaire. RESULTS: The study included 25 female patients with a mean age of 36.48 ± 5.87 years. The mean period of follow-up was 30.32 ± 5.82 months. Local recurrence was encountered in 1 patient (4%). The mean volume reduction of the injected fat graft was 27.36 ± 8.58%. Twenty-three patients (92%) declared their satisfaction after the operation, one of them was satisfied only after she underwent a second session of lipofilling. CONCLUSIONS: Skin-preserving mastectomy with the enhancement of the LD by lipofilling for immediate reconstruction of the breast seems to be a safe and simple technique for the achievement of autologous breast reconstruction. It has an acceptance rate of locoregional recurrence and minor postoperative complications. The procedure showed high postoperative patients' satisfaction and a reasonable percentage of fat resorption as confirmed by volumetric CT imaging techniques.

Relationship of serum haemojuvelin and hepcidin levels with iron level and erythropoietin requirement in prevalent hepatitis C virus positive haemodialysis patients.

AIM: Iron overload is frequently reported in haemodialysis (HD) patients particularly those with chronic hepatitis C virus (HCV) infection. Soluble haemojuvelin (sHJV) has recently emerged as one of the significant regulators of iron homeostasis and hepcidin expression. The aim of the present study was to evaluate the potential associations of sHJV and hepcidin with inflammation, iron parameters and erythropoietin requirement in prevalent HD patients with HCV. METHODS: Serum sHJV and hepcidin were measured in 60 prevalent HD patients with [group I (n = 30)] and without [group II (n = 30)] HCV, and controls (n = 30) by enzyme-linked immunosorbent assay. Parameters related to anaemia, iron metabolism, inflammation, sHJV and hepcidin were measured. RESULTS: Serum hepcidin in HCV positive versus negative groups was 89.40 ± 46.08 ng/mL and 224.1 ± 72.36 ng/mL, P = 0.000, respectively, while sHJV was 245 ± 1.338 ng/mL and 254 ± 0.762 ng/mL, P = 0.147, respectively in positive versus negative patients. In group I, hepcidin correlated with serum ferritin (r = -0.512 P = 0.005) and transferrin saturation (TSAT%) (r = 0.572, P = 0.000) and sHJV correlated with ferritin (r = 0.40, P 0.000), TSAT% (r = 0.450, P = 0.002) and a significant correlation also existed between sHJV and hepcidin (r = -0.259, P = 0.045). In the regression analysis, ferritin and TSAT% were able to predict sHJV; (standardized ß = 0.52, P 0.001) and (standardized ß = 0.48, P 0.010). Ferritin and sHJV were also able to predict hepcidin (standardized ß = 0.627, P = 0.006) and (standardized ß = 0.300, P = 0.007) in group I. CONCLUSION: Soluble haemojuvelin levels seem to be associated with iron overload parameters and hepcidin levels in HCV positive HD patients.

Evaluation of therapeutic mammoplasty techniques in the surgical management of female patients with idiopathic granulomatous mastitis with mild to moderate inflammatory symptoms in terms of recurrence and patients' satisfaction.

BACKGROUND: Although idiopathic granulomatous mastitis (IGM) affects young females, its surgical management usually leads to disfigurement of the breasts. OBJECTIVES: To assess the use of therapeutic mammoplasty techniques for management of IGM in terms of recurrence and postoperative patients' satisfaction. METHODS: This prospective clinical study included thirteen patients who were diagnosed histologically as IGM. Patients with moderate to large breasts, who had a breast mass between 20-50% of the breast size with failed medical treatment or intolerability to steroids were subjected to therapeutic mammoplasty techniques. Only patients with large breasts were offered contra-lateral reduction mammoplasty to resume symmetry and achieve better aesthetic results. RESULTS: Early postoperative bleeding that was encountered in one patient (7.7%) was the only serious postoperative complication. Patient was re-operated and the bleeder was secured. Recurrence occurred in 2 patients (15.4%) at 16 and 24 months after the operation. Kyungpook National University Hospital (KNUH) breast reconstruction satisfaction questionnaire used to assess patients' satisfaction 6 months after the operation and revealed that 10 patients (76.9%) were satisfied after the operation. CONCLUSION: Using therapeutic mammoplasty techniques in surgical management of IGM in moderate to large breasts seems justifiable with good results regarding recurrence and postoperative patients' satisfaction.
