INTRODUCTION: Triple negative breast carcinomas (TNBC) account for approximately 15-20% of all breast carcinomas. This subtype is characterised by an unfavourable prognosis with early locoregional recurrence a metastases. Only few studies have focused on the impact of local surgery on the overall therapeutic outcome. However, decisions are difficult to make in the case of TNBC, and no particular molecular subtype or marker exists that would make the decision-making process easier. The aim of our retrospective study was to analyse the TNBC surgical management outcomes at EUC Clinic in Zlin. METHODS: 440 women with breast carcinoma were operated on at EUC Clinic from 2014 to 2016, including 29 patients with TNBC; bilateral carcinoma was present in one case. Neoadjuvant chemotherapy (NAC) was indicated in 6 cases. The tumour centre was marked with a clip. The extent of surgery depended on the residual size of the tumour. Sentinel lymph node biopsy was indicated in clinically negative lymph nodes; further management followed the Z0011 study if the biopsy was positive. Axillary lymph node dissection was performed after NAC. In all cases, surgery was followed by systemic chemotherapy, and by radiotherapy in the case of breast-conserving procedures. RESULTS: The group included 29 women and one patient with bilateral carcinoma, i.e. 30 cases of TNBC. Mean age was 57 years and median age was 55.5 years. Mean follow-up was 62.9 months, with the median of 69.9 month. NAC was indicated in 6 patients; complete pathological response was achieved in one case. NAC was followed by mastectomy in 5 cases including a bilateral procedure in one case, and by breast-conserving surgery in one case. Axillary dissection was performed in all cases. Breast-conserving surgery and sentinel node biopsy predominated in the group (16 cases). Local recurrence was observed in 4 cases, 2 times as an isolated local recurrence after one year and 2 times as part of generalization, always after mastectomy. Six patients died of generalized disease. No regional recurrence was observed. CONCLUSION: TNBC is characterised by a worse prognosis and a higher rate of local recurrence. As confirmed by our study, the results of breast-conserving surgery can be comparable to those of radical procedures, and thus radical surgery should be indicated prudently.

Ductal carcinoma in situ (DCIS) is a very heterogenous disease. The incidence of DCIS has been increasing with the adoption of mammography screening. This opened new questions concerning surgical and adjuvant therapy. Methods: We retrospectively observed the incidence of DCIS amongst the patients that underwent surgical resection in EUC clinic Zlín between 2017 and 2019. We also assessed the extent of breast surgery including interventions in axilla and the adjuvant therapy. Results: There were 616 breast cancer patients, of whom 44 (7.1%) were diagnosed with DCIS. Breast-conserving surgery was performed in 35 (80%) patients. Lumpectomy alone was performed in 21 (47%) patients. Mastectomy was indicated primarily in 9 cases with additional two mastectomies performed to achieve clear margins. All sentinel nodes were negative. Conclusion: Results confirmed, that the surgical therapy as well as radiotherapy and hormonal treatment are performed according to guidelines at our department. Proportion of sentinel node biopsy is remarkably higher, therefore an improvement in this area is our next goal.

Sentinel lymph node biopsy (SLNB) has emerged as an alternative to axillary lymph node dissection during breast cancer surgery during the last 2 decades. However, there are several controversies regarding the indication of the sentinel node biopsy after neoadjuvant chemotherapy which can convert positive lymph nodes to negative. The false-negative rate after neoadjuvant chemotherapy is unacceptably high. This high false-negative rate can be decreased by marking of the positive lymph nodes and removal during sentinel lymph node biopsy procedure in addition to the sentinel lymph nodes. The aim of this study was to investigate the possibility of carbon tattooing of the positive sentinel lymph nodes before neoadjuvant chemotherapy. In 2016, a prospective protocol was launched investigating the black carbon tattooing procedure of the suspective and positive axillary lymph nodes by injecting 0.1-0.5 carbon ink in normal saline under ultrasound guidance. All patients underwent black carbon tattooing of the suspected or positive axillary lymph nodes before the chemotherapy or one week before the primary surgery when chemotherapy was not indicated in the neoadjuvant setting. Sentinel lymph nodes together with lymph nodes marked by the black carbon ink were removed and histologically evaluated. So far 27 patients were treated under this protocol. Breast saving surgery was performed in 22 cases and mastectomy in 5 cases. All patients had invasive ductal carcinoma. In 20 patients neoadjuvant chemotherapy was indicated and in 7 patients primary surgery was performed. All lymph nodes marked by black carbon ink were successfully identified and removed. Sentinel lymph node biopsy was performed in 8 cases and sentinel lymph node biopsy followed by axillary dissection in 15 cases. Axillary dissection alone was performed in 4 cases. In 19 cases, the black carbon ink was present in the sentinel lymph node at the same time and in 4 cases carbon dye was present in other lymph nodes than the lymph node identified during SLNB, which corresponds to 17.4%. In the group of patients undergoing primary surgery, in one case from six, the sentinel lymph node was negative and the lymph node marked with carbon ink positive which represents false-negative lymph node and failure of the SLNB procedure. After neoadjuvant chemotherapy, there was no false-negative lymph node identified, but the conversion of the positive lymph nodes to negative was present in 10 cases (50%). There were no complications attributed to carbon ink tattooing. The results of positive sentinel lymph nodes tattooing have confirmed that this method is safe and allows a decrease in the false negativity rate during the sentinel node biopsy procedure.

INTRODUCTION: Neoadjuvant therapy (NT) applied before breast cancer surgery can lead in favourable cases to regression of the tumor or its total disappearance - pathological complete response (pCR). Due to downstaging after NT, the extent of the surgery can be reduced. pCR represents an important prognostic factor for survival. The aim of this study was to evaluate the effectiveness of NT resulting in pCR on our sample of patients and to assess the frequency of locoregional recurrence (LRR) depending on the extent of the surgery in postoperative care. METHODS: This retrospective study was performed on a sample of 96 patients who underwent breast cancer surgery between 2006 and 2018 after previous NT. On the basis of the histological examination after surgery we evaluated the degree of regression and thus also pCR. In postoperative care we followed the patients for any occurrence of LRR in the breast and axilla. RESULTS: pCR (Chevallier 1) was observed in 26 cases - 27.1%. During follow-up in postoperative care, 8 cases of LRR occurred - 8.3% (5.2% after mastectomy and 2.1% after breast-conserving surgery). Mean follow-up was almost 30 months with the median of 26.5 months. CONCLUSION: With the development of new NT procedures a significant rise in pCR has occurred, predominantly in HER 2+ and triple negative subtypes, thus leading to a decreased incidence of LRR. The number of breast-conserving surgeries with sentinel lymph node biopsy is rising. In a select group of patients breast-conserving surgery is safe and is associated with a low number of LRR events.

INTRODUCTION: Papillary thyroid cancer (PTC), especially micropapillary variant (MPTC), is the most common thyroid malignancy. Biological behavior is not aggressive and the patients prognosis is satisfactory. The objective of our comparative retrospective study was to evaluate whether the incidence is rising in the Region of Zlín and if less extensive approach was adopted by Czech endocrinologists. METHODS: We compared 2 groups from years 2005-2008 and 2014-2018. The incidence of thyroid cancer, the PTC and the MPTC, the extent of the surgery and the lymphadenectomy, number of removed lymph nodes and the number of positive lymph nodes were observed. RESULTS: We gathered 1353 patients in group 1. We found 220 malignancies (16.3%), 180 (81.8%) were PTC with MPTC variant in 44.4% (80 patients). All patients underwent a total thyroidectomy. We made 18 central and 10 lateral lymphadenectomies, 280 lymph nodes were collected with meta-stasis in 29,3 %. In group 2 with 1569 patients we found 318 (20.3%) carcinomas, PTC in 302 (94.6%) cases. The MPTC accounted for 215 (67.4%) cases. 10 patients with MPTC underwent hemithyroidectomy only. Numbers of central and lateral lymphadenectomies rose to 52 and 24 respectively. We gathered 376 lymph nodes with proven metastasis in 44.4% of these nodes. CONCLUSION: Both, the incidence and the frequency of PTC and MPTC are rising in our region. However, the number of less invasive procedures is not increasing significantly despite representing a sufficient way of treatment. We need wider adoption of these evidence-based recommendations by indicating endocrinologists in the Czech Republic.

INTRODUCTION: Bipolar radiofrequency-induced thermotherapy of advanced stage haemorrhoid disease has been used successfully at the Atlas Hospital in Zlin for ten years. The aim of this study was to evaluate long-term outcomes of the method. METHOD: RFITTH is bipolar radiofrequency-induced thermotherapy of haemorrhoidal diseases. High frequency electric current causes thermal coagulation of tissue. The procedure results in the elimination or significant reduction of prolapse and bleeding of hemorrhoids. RESULTS: 228 RFITTH procedures were performed in 217 patients at the Department of Surgery at the Atlas Hospital from 9/2007 to 1/2017. The group consisted of 134 men and 94 women, the average age was 51 years. 107 operations were performed in stage III and 121 in stage IV. Complications of the procedure involved postoperative fissure occurring in 20 patients (8.7 %). Thrombotic haemorrhoid developed in 6 patients (2.6 %), hyperspasm of the sphincters in 9 patients (3.9 %). Prolapse of the rectal mucosa was diagnosed in 4 patients (1.7 %). The disease recurred in 9 patients and 10 reoperations were performed (3.9 %). CONCLUSION: The method is a safe miniinvasive therapeutic option for advanced stage haemorrhoidal disease. Key words: RFITTH - haemorrhoidal disease - radiofrequency coagulation.
INTRODUCTION: Conservative procedures in early breast carcinoma are a safe alternative to mastectomy. The resection line is controversial, as well as the presence of residual malignant cells in the breast after excision and their influence on local recurrence. The aim of the study was to assess the presence of residual cells in re-excised tissues near positive resection lines, in the distance up to 2 mm, and 2-5 mm. The distance of more than 5 mm was evaluated as free margin. METHOD: All patients operated on in Atlas Hospital from 2004 to 2008 using conservative surgery were included in study. The resection line and the presence of residual malignant cells were followed in positive margins and in the distance of the resection line from the tumour up to 2 mm, and 2-5 mm. RESULTS: The conservative procedure was indicated 330 times, and 78 patients were re-operated for insufficiently free margins. The conservative procedure was completed 311 times, and mastectomy was done as the final procedure in 19 cases. Positive resection line was found 10 times. Distance up to 2 mm occurred 12 times and 25 mm 56 times. In all re-operated patients, presence of malignant cells in the re-excised tissue was found 31 times (39.7%). Repeated surgery for positive line, i.e. tumour present in the resection line, was done 10 times while malignant cells were found in all patients; for the distance up 2 mm, repeated surgery was done 12 times and 3 cases were positive (25%). For the distance of 2-5 mm, repeated excision occurred 56 times and 18 cases were positive, i.e. 32.1%. CONCLUSION: For the resection line "no tumour in contact with ink", presence of malignant cells in breast tissue must be expected in one third of the cases.Key words: breast carcinoma - conservative surgery - residual malignant cells.
The essential aim of oncology surgery including breast cancer is to remove the malignant tumour and lymph nodes. For many decades, dissection of axillary lymph nodes has been a common part of mastectomy, virtually the only surgical procedure in breast cancer treatment until the 90ies of the previous century. Although mastectomy has been replaced with breast preserving procedures, axillary dissection remained an integral part of the surgery. Sentinel lymph node biopsy (SLNB) has introduced a revolutionary change in breast cancer treatment in the axilla, replacing dissection in clinically negative axillary nodes. As a result, the number of radical procedures in the axilla was significantly limited, as well as the incidence of serious complications that may have a negative impact on the quality of life of the patients. As shown by other studies, the number of dissections can be reduced even further. Subsequent axillary dissection is unnecessary where the sentinel nodes contain only malignant cells, micrometastases and even a limited number of macrometastases. SLNB can also be used in a selected group of patients after neoadjuvant chemotherapy.Key words: breast carcinoma - axillary dissection - sentinel lymph node - micrometastases - macrometastases.
INTRODUCTION: Hidradenitis suppurativa is a chronic, recurrent inflammatory disease causing significant changes and damage to skin. Predilection sites are the axilla and the anogenital region. Chronic and severe forms of the diseases may cause both physical and psychological injury to the patient. PATIENTS: We present the cases of two female patients with severe hidradenitis suppurativa in the axillae and in the anogenital region. The patients had been unsuccessfully treated for eight and four years respectively with antibiotics and by limited surgery. Different methods of closing the defects following radical surgical excision (local flap reconstruction, healing by granulation) had to be used with respect to the extent of the disease and the site of involved skin. CONCLUSION: Radical wide excision of the skin area involved is the only appropriate surgical procedure which prevents recurrence of the disease. Selection of the therapeutic method must be done very carefully with respect to the individual characteristics of the disease and the patients attitude to therapy.

BACKGROUND: Papillary thyroid carcinoma (PTC) is the most common malignant thyroid tumour. A common mutation of papillary thyroid carcinoma (PTC) is the somatic mutation of the BRAF (V600E) gene. AIM: The aim was to 1) determine the association of lymph node metastases of PTC with the BRAF gene mutation of primary tumour; 2) evaluate association of the BRAF mutation in the -primary tumour with clinicopathological para-meters; 3) examine the extent of genetic heterogeneity by monitoring the BRAF mutation in multicentric tumours. SUBJECTS AND METHODS: Retrospective analysis of the BRAF (V600E) mutation in PTC and PTC neck lymph node metastases in 156 patients operated from 2003 to 2012 in Prague and Zlín, the Czech Republic, using a qPCR assay. The results were correlated with clinicopathological factors. RESULTS: DNA was successfully extracted from 137 samples. The BRAF (V600E) mutation was detected in 78 cases (56.9%). The patients with BRAF p.Val600Glu mutation of primary tumour had only non-significantly higher risk of cervical lymph node metastases [OR=2.39 (95%) CI 1.00-5.75, p=0.052]. In the classic papillary variant, the BRAF (V600E) mutation was found significantly more often than in other PTC subtypes (p=0.022). We did not confirm any significant association between the BRAF (V600E) mutation and other clinicopathological findings. CONCLUSION: Except for the higher prevalence in papillary variant of PTC, BRAF p.Val600Glu mutation was not associated with other prognostic clinicopathological factors of PTC. BRAF mutation cannot be regarded as a reliable marker of node metastases in patients with PTC.
