Iodine seed localisation of non-palpable lesions in breast surgery first experience.

Surgical therapy of non-palpable malignant breast lesions requires precise preoperative localisation. Recently, radioactive iodine seed localisation has excelled among the number of localisation methods. We present our first experience with this method at our department. We describe the structure of the radioactive iodine seed, the principles of preoperative localisation and peroperative detection of the seed, the specimen transport process, histopathological examination, storage and disposal of the seed, as well as aspects of radiation protection.

Pagets disease of the breast - observational retrospective study of the past 20 years.

INTRODUCTION: Pagets disease of the breast (PD) is a rare type of carcinoma that affects the skin of the nipple-areolar complex. Unresolved issues exist regarding its diagnosis and therapy. The aim of the study was to gather data on how the therapy of the disease is approached in clinical practice, and to formulate current diagnostic and therapeutic recommendations. METHODS: Retrospective evaluation of data from medical records of patients with PD who underwent surgery at our department between 2001 and 2020. The data was evaluated using basic statistical methods. RESULTS: Sixty four female patients with the mean age of 62.5 years. In 58 women, PD was confirmed before surgery, with the median of 20 weeks from initial symptoms to diagnosis. Forty seven of the patients were operated for presumed isolated PD; in 38 cases, histopathological evaluation of the specimen revealed an associated malignancy in the mammary gland. Primary breast-conserving surgery (BCS) was performed in 46 patients; surgical revision was indicated in 17 cases. In 6 patients with PD associated with non-invasive breast cancer treated by BCS without radiotherapy (RT), a local recurrence appeared in 3 cases, which is significantly more compared to the group of patients undergoing total mastectomies (p=0.032). No local recurrence appeared in 9 cases of isolated PD treated by BCS, including 6 patients without RT. The tumors associated with PD were mostly ER-negative (44/57) and HER2-positive (22/25). CONCLUSION: In cases where PD is suspected, careful clinical examination and the use of available diagnostic imaging techniques including MRI are appropriate. BCS without RT is not an adequate oncological therapy where an associated malignancy of the breast is found.

Targeted axillary dissection and sentinel lymph node biopsy in breast cancer patients after neoadjuvant chemotherapy - a retrospective study.

INTRODUCTION: No consensus exists as yet regarding the optimal extent of surgery on the lymph nodes in breast cancer patients after neoadjuvant treatment. In addition to axillary dissection and sentinel lymph node biopsy (SLNB), a new approach called Targeted Axillary Dissection (TAD) was introduced. It requires the marking of metastatic nodes before the neoadjuvant treatment. METHOD: A retrospective observational study on patients with breast cancer and neoadjuvant chemotherapy treated surgically at a single institution in 2017. RESULTS: The analysis included 121 cancers in 120 patients. Clinical regression of lymphadenopathy occurred in 29 out of 74 cases. Axillary dissection was performed 34x, SLNB 52x and TAD 35x. In TAD procedures, the marked lymph node was found 30x and was among the sentinel nodes in 19 cases. No case occurred in which the marked node was assessed as negative with a metastasis found in the other nodes. On the contrary, there were 3 cases with negative sentinel nodes whereas the marked node was positive. Out of 74 cases with initially pathologic nodes, 23 patients were spared axillary dissection. CONCLUSION: Clinical assessment of the lymph node status is rather inaccurate. In cases with initially pathologic nodes we recommend marking of the most explicit metastatic node to enable TAD. The marked node is likely to reflect the status of the lymph nodes after neoadjuvant treatment more accurately than common sentinel nodes. A considerable proportion of patients can be spared axillary dissection in this way. However, the long-term oncologic safety of TAD still needs to be verified. Key words: breast cancer - neoadjuvant treatment - axillary dissection - sentinel lymph node biopsy - targeted axillary dissection.

[Lymphoedema Following Regional Lymph Node Surgery for Breast Cancer]. / Lymfedém po operacích na spádových lymfatických uzlinách pro karcinom prsu.

BACKGROUND: The treatment of breast cancer is based on the multimodal principle and surgery of regional lymph nodes is an inseparable part of this. Indication criteria are changing constantly folowing advances in other modalities. It is necessary to consider not only the diagnostic or therapeutic benefit but also to take into account adverse effects. Previous studies have demonstrated that axillary dissection (ALND) is burdened by a high frequency of chronic lymphoedema of the arm or chest wall; however, a considerable percentage of patients may also suffer from lymphoedema after sentinel lymph node biopsy (SLNB). AIM: This paper focuses on the pathophysiology of lymphoedema, its potential predictive factors, and its complications. Furthermore, it presents an overview of published studies comparing the incidences of lymphoedema after current axillary surgery for breast cancer together with current trends designed to radically reduce the number of these operations. It also briefly refers to the possibilities of implementing preventive or therapeutic operations for lymphoedema. CONCLUSIONS: Both ALND and SLNB are burdened by a clinically significant risk of lymphoedema. This risk is more serious after ALND. In the medium term, approximately 7-59% of operated patients suffer from lymphoedema. The incidence of lymphoedema after SLNB, considered a very gentle method, is also not negligible (0-14%). As the number of patients surviving breast cancer treatment continues to increase, monitoring the undesirable effects of axillary surgery over the long term will become more important. The results of published studies support research into treatment methods that have the potential to reduce the radicality of axillary surgery while preserving or improving total medical effectiveness.Key words: breast neoplasms - sentinel lymph node biopsy - axillary dissection - adverse effects - breast cancer lymphedemaThis work was supported by the grants MEYS - NPS I - LO1413 and MH CZ - DRO (MMCI, 00209- 805).The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study.The Editorial Board declares that the manuscript met the ICMJE recommendation for biomedical papers.Submitted: 7. 11. 2016Accepted: 5. 12. 2016.

[Breast cancer patient satisfaction with immediate two-stage implant-based breast reconstruction]. / Spokojenost onkologických pacientek s okamzitou dvoudobou aloplastickou rekonstrukcí prsu.

BACKGROUND: For most breast cancer patients in the Czech Republic, breast reconstruction is available only in a delayed manner. In the Masaryk Memorial Cancer Institute (MMCI), suitable candidates are offered immediate breast reconstruction using tissue expander with later exchange to a permanent silicone implant. The aim of this study was to assess patient satisfaction with this type of reconstruction. PATIENTS AND METHODS: Sixty-two women who had undergone surgery at the MMCI from 2007 through 2013 were sent a simple questionnaire developed by our working team. Fifty-seven patients completed the questionnaire. The data were evaluated by description methods and statistical tests. RESULTS: Patient response was 92%. The absolute majority of patients (56/57) would opt for this method again. The vast majority of patients (48/57) are generally satisfied with their reconstruction. Most women (8/14) younger than 50 years after the unilateral surgery would prefer synchronous contralateral prophylactic mastectomy and bilateral reconstruction if they could choose again. After bilateral surgery, reconstructed breasts are more often regarded as a part of the patients body. Dressed women rate their look substantially better than when they are undressed. As for self-esteem, these women are feeling excellent or good. Their psychosocial well-being in common situations is predominantly excellent. Their sexual well-being is significantly worse, and almost half of these women indicate occasional pain in their reconstructed breasts. The patients emphasize the need for appropriate information before the surgery. CONCLUSION: Immediate two-stage implant-based breast reconstruction is a suitable option for some breast cancer patients. With regard to the less natural cosmetic result and feeling of the implant-reconstructed breast, appropriate selection of women for this type of surgery is necessary and potential candidates must be thoroughly informed in the preoperative setting.

[Surgical treatment of breast cancer in the Masaryk Memorial Cancer Institute]. / Chirurgická 1écba karcinomu prsu v MOU.

Breast cancer represents the most frequent malignancy in women in the Czech Republic. Although surgery plays the basic role in the therapy of its early stages there hasn't existed any specialized training in surgical oncology in our country so far. Majority of patients are surgically treated at departments of general surgery where sometimes outdated procedures are used as we know from our own experience. In the Masaryk Memorial Cancer Institute we perform approximately 500 breast surgeries a year and provide a team of surgeons specialised in this field. The aim of our article is to give a basic review of modern techniques in breast cancer surgery, to describe more precisely the most frequent ones and to give a list of some relevant literary sources.
