This study describes the experience of radical mastectomies with simultaneous breast reconstruction using TRAM flap in patients with inflammatory breast cancer. The study aimed to evaluate the effectiveness of primary breast reconstruction using the TRAM-flap procedure in patients with an inflammatory form of breast cancer. Our work is associated with some deviation from generally accepted standards: delayed breast reconstruction after radical mastectomy for inflammatory breast cancer. We describe the experience of radical mastectomies with the simultaneous reconstruction of the breast using a TRAM flap in patients with inflammatory breast cancer. This study included 12 patients diagnosed with breast cancer stages IIIB and IIIC. Almost all patients (eleven out of twelve patients) underwent radical mastectomy with one-stage reconstruction using a TRAM flap after chemotherapy. Two years later, one patient (8.3%) showed disease progression in the form of distant metastases in the bones of the spine. One patient (8.3%) had a regional relapse in the displaced flap near the postoperative scar. The rest of the patients (83.4%) showed no signs of continuing the disease. Patients with one-stage breast reconstruction improved socially, and their subjective well-being was better than those who underwent radical mastectomy without reconstruction. Experience in performing one-stage reconstructions in the surgical treatment of patients with inflammatory breast cancer is a reason for restrained optimism regarding the possibility and feasibility of these operations.

Introduction. Breast cancer (BC) is an important public health problem. These are BC patients in young age, hereditary (BRCA-associated) BC patients, inflammatory BC patients, synchronous cancer patients etc. In case of a large size of tumor or diffuse form of BC we often need to use extended surgery techniques in order to perform it radically and minimize a risk of recurrence. The aim of the study to evaluate the effectiveness of surgery approaches in inflammatory BC patients. Materials and research methods. Тhe first stage of our research was to evaluate extended surgical treatment using techniques by Handelhail and Beck on the risk of local recurrence. The study included 39 patients with breast cancer T4b-dN0-3M0 who in the period from 2014 to 2019 received complex treatment at National Cancer Institute of Ukraine. Besides neo- and adjuvant chemotherapy, an extended radical mastectomy using a technique by Handelhail and Beck was performed in 19 patients. In 20 patients a traditional (Madden) modified radical mastectomy was done. Results. When studying the data of a group of 20 patients we received a very high percentage of recurrence. Recurrences were classified as locoregional if they occurred in the ipsilateral breast or the axillary or supraclavicular lymph nodes, and as distant metastasis, if they occurred at any other site. Radical extended modified mastectomy consisted in the removal of the mammary gland and adjacent skin along the perimeter with subcutaneous tissue at a distance of 2-3 cm outward from the macroscopic edges of the gland, subclavian-axillary-subscapularis lymphadenectomy. The resulting defect was closed using a technique by Handelhail and Beck. The use of extended surgery made it possible to improve recurrence-free survival.

Expression of pro-malignant factors (VEGF) and cytokines like inflammatory components support breast cancer development. We examined 46 patients with stage IIIB inflammatory breast cancer (IBC) and 24 with stage IIA-IIIB breast cancer (BC) without secondary edema. Hormone receptors, Her-2/neu, Ki-67 index, VEGF, and IL-6, were determined for all patients before and after neoadjuvant treatment. They associated the expression of VEGF for IBC patients with an unfavorable prognosis. VEGF level for IBC lymph node metastases was higher than in patients without such lesions (1.4 times), and there was a significant increase in VEGF levels in the G3 category of malignancy (1.54-fold increase). In IBC patients with positive HER2/neu status, VEGF levels were 1.51 times higher compared to those with negative HER2/neu status (r=0.36, p<0.05). IL-6 level during therapy in IBC patients remained high, which occurs in active tumor development. Comparative analysis of the VEGF/IL-6 ratio during treatment of patients with IBC was higher vs. IIIB stage breast cancer without edema (1.4 vs. 0.7), indicating the aggressiveness of the tumor process and confirmed by an objective response to treatment (regression<30%).

Introduction. Cancer mortality in diabetic patients has been reported to increase moderately compared to non-diabetic patients. The aim of the study aimed to assess the findings and identify radiotherapy's role in the comprehensive care of diabetic IBC patients with various hyperglycemia correction strategies. Methods. Patients with diabetes have shown a higher risk of radiation-induced cancer progression for tumor tissue, especially for inflammatory form. For 7 patients, to continue systematic chemotherapy with a scheme change (consecutive anthracyclines-taxanes, 2-week interval) and insulin with individual scheme for hyperglycemia correction on the basis of glycemic control – 1st group, the other (7 patients) – 2nd group, was given radiotherapy to the breast gland and lymphatic drainage ways. 45–50 Grey was prescribed for 25-28 fractions (per 1.8-2.0 Grey), 46–50 Grey in 23-25 fractions were used for zones of regional metastasis and for hyperglycemia correction metformin 2000 mg/day PO divided q8-12hr with meal on the basis of glycemic control. Results. Assessed were the number of patients who qualified for surgery and overall survival for 24 months. 2nd group showed a superior response following resistance to prior systemic treatment. Thus, 5 (71.41%) of the 7 patients exhibited a consistent response – complete or partial regression. There were only 2 individuals (28.61%) who responded to treatment among the patients who maintained chemotherapy. Conclusions. Breast cancer of the aggressive IBC variety requires multidisciplinary treatment from breast surgery, medical, and radiation oncology. Patients with diabetes appear to experience more side effects from radiation therapy than patients without the disease. Hyperglycemia, higher total RT doses, and radiosensitizers are a few techniques that can improve the impact of RT on local-regional management. Local-regional control rates for IBC are increasing with an individual patient strategy. Metformin also improves insulin resistance and has anticancer benefits.
