RESUMO
INTRODUCTION: For many years, the gold standard in the localization of non-palpable malignant breast tumors has been the use of wire-guided method. However, this has recently been replaced by more modern localization techniques in many institutions. METHODS: This is a retrospective case-control study comparing two localization techniques (iodine seed 125I and wire-guided localization) for localizing non-palpable tumors in patients with histologically verified breast carcinoma. RESULTS: The study included 62 patients - 31 with localization of malignant breast tumor by iodine seed (subgroup 125I) and 31 by wire-guided localization (subgroup FV). The average volume of the resected tissue in subgroup 125I (46.2 cm3) was statistically significantly smaller compared to subgroup FV (83.7 cm3; P = 0.0063). R0 resection was achieved in 29 cases (93.5%) in subgroup 125I and in 24 cases (77.4%) in subgroup FV (P = 0.0714). In subgroup 125I, re-resection was not indicated in any case, while in subgroup FV, re-resection due to tumor reaching the margin was indicated in 6 cases (19.4%; P = 0.01). CONCLUSION: Our initial experience show that the use of iodine seeds for localizing non-palpable breast tumors is associated with the removal of a smaller volume of resected tissue compared to wire-guided localization, with a trend towards more frequent achievement of R0 resection. In the subgroup of patients localized with iodine seeds, there was a smaller proportion of re-resections due to inadequate safety margins.

INTRODUCTION: Postoperative complications in patients with breast cancer delay the initiation of adjuvant therapy, prolong the length of hospitalization and reduce the patients' quality of life. Although their incidence can be influenced by many factors, the connection with the type of drain is insufficiently studied in the literature. The aim of this study was to assess whether there is an association between the use of a different drainage system and the occurrence of postoperative complications. METHODS: The data of 183 patients included in this retrospective study were collected from the information system of the Silesian Hospital in Opava and then statistically analyzed. These patients were divided into two groups according to the type of drain used - a Redon drain (active drainage) was used in 96 patients, and a capillary drain (passive drainage) was used in 87 patients. The incidence of seromas and hematomas, the duration of drainage and the amount of wound drainage were compared between the individual groups. RESULTS: The incidence of postoperative hematomas was 22.92% in the group of patients with the Redon drain, and 10.34% in patients with the capillary drain (p=0.024). The incidence of postoperative seromas was comparable for the Redon drain (39.6%) or the capillary drain (35.6%) (p=0.945). No statistically significant differences were found in the drainage time or the amount of wound drainage. CONCLUSION: A statistically significantly lower incidence of postoperative hematomas was observed when using a capillary drain compared to the use of a Redon drain in patients after breast cancer surgery. The drains were comparable with respect to seroma formation. None of the studied drains was significantly more beneficial in terms of the total drainage time and the total amount of wound drainage. KEY WORDS: breast cancer, postoperative complications, drain, hematoma.

INTRODUCTION: Sebaceous carcinoma is a rare malignant tumor of the sebaceous glands. Sebaceous carcinoma occurs mainly in the head and neck region, rarely in trunk. Case report: We present a case report of 63-year-old patient, operated on for sebaceous carcinoma in the right breast area. The patient underwent radical surgery, removal of the tumor with the skin, subcutaneous tissue, and the large pectoral muscle. The patient is in good clinical condition eight months after the surgery. She is being constantly monitored and so far, there are neither signs of local recurrence nor tumor progression. Conclusion: Patients with rare tumors should be treated comprehensively with subsequent lifelong dispensarisation in specialized centers. Multidisciplinary medical teams are able to eruditely diagnose, recognize, treat and dispense patients.

INTRODUCTION: The role of sentinel lymph node biopsy (SLNB) in patients with breast cancer after neoadjuvant chemotherapy (NAC) is currently under discussion. The aim of our study was to determine the false negativity rate (FNR) of SLNB, the accuracy of ultrasound examination in the evaluation of the status of lymph nodes and the accuracy of perioperative cryobiopsy of the sentinel lymph node (SLN). METHODS: Prospective multicentre study, which took place in years 20182020 at three centres in the Czech Republic. A total of 59 patients were evaluated. RESULTS: The FNR of SLNB in the group of patients with cN1 before NAC and ycN0 after NAC was 12.5%. The FNR of perioperative histological examination of the SLN was 38.5%. The FNR of ultrasound examination of axillary lymph nodes in patients after NAC was 35.5%, and the false positivity rate was 16.7%. The incidence of inflammatory complications in our cohort was 3.3%. CONCLUSION: The FNR of SLNB in the group of patients with cN1 before NAC and ycN0 after NAC exceeds the tolerable limit of 10%. The FNR of perioperative histological examination of the SLN is high; definitive histological examination of the SLN may change the original diagnostic-therapeutic plan. Ultrasound examination of the axillary lymph nodes in patients after NAC is a method with high false negativity and positivity and may not correspond with the perioperative finding. The incidence of inflammatory complications in our cohort in patients after NAC is comparable to literature data on the frequency of complications in patients without NAC.

INTRODUCTION: The aim of this pilot retrospective study is to evaluate the complication rate in patients after axillary dissection comparing preparation with harmonic scalpel vs traditional ligation technique, and to analyse risk factors for complications occurrence. METHODS: 144 patients with 148 axillary dissections operated in a single centre between January 2014 and 2019 were included into the study. Axillary dissection was performed using harmonic scalpel in 73 and absorbable ligations in 70 cases. RESULTS: Seroma formation was observed in 41 patients (56.2%) in the harmonic scalpel group and in 21 patients (30.0%) in the ligations group (p=0.003). The mean period from the surgery to drain removal was 4.0 days in the harmonic scalpel group and 3.0 days in the ligations group (p<0.001). The mean amount of the drained fluid after mastectomy was 300.9 ml in the harmonic scalpel group and 168.7 ml in the ligations group (p=0.005); after breast conserving surgery, it was 241.9 ml and 107.4 ml, respectively (p =0.023). CONCLUSION: In comparison with traditional ligations with absorbable material, axillary dissection using harmonic scalpel significantly increases the risk of postoperative seroma formation, prolongs the time from the surgery to drain removal, and increases the amount of drained fluid.
