RESUMO

BACKGROUND: Tailored axillary surgery (TAS) is a novel surgical concept for clinical node-positive breast cancer. It consists of the removal of the sentinel lymph nodes (LNs), as well as palpably suspicious nodes. The TAS technique can be utilized in both the upfront and neoadjuvant chemotherapy (NACT) setting. This study assessed whether/how imaging-guided localization (IGL) influenced TAS. PATIENTS AND METHODS: This was a prospective observational cohort study preplanned in the randomized phase-III OPBC-03/TAXIS trial. IGL was performed at the surgeon's discretion for targeted removal of LNs during TAS. Immediate back-up axillary lymph node dissection (ALND) followed TAS according to TAXIS randomization. RESULTS: Five-hundred patients were included from 44 breast centers in six countries, 151 (30.2%) of whom underwent NACT. IGL was performed in 84.4% of all patients, with significant variation by country (77.6-100%, p < 0.001). No difference in the median number of removed (5 vs. 4, p = 0.3) and positive (2 vs. 2, p = 0.6) LNs by use of IGL was noted. The number of LNs removed during TAS with IGL remained stable over time (p = 0.8), but decreased significantly without IGL, from six (IQR 4-6) in 2019 to four (IQR 3-4) in 2022 (p = 0.015). An ALND was performed in 249 patients, removing another 12 (IQR 9-17) LNs, in which a median number of 1 (IQR 0-4) was positive. There was no significant difference in residual nodal disease after TAS with or without IGL (68.0% vs. 57.6%, p = 0.2). CONCLUSIONS: IGL did not significantly change either the performance of TAS or the volume of residual nodal tumor burden. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03513614.

RESUMO

PURPOSE: The aim of this study was to evaluate clinical practice heterogeneity in use of neoadjuvant systemic therapy (NST) for patients with clinically node-positive breast cancer in Europe. METHODS: The study was preplanned in the international multicenter phase-III OPBC-03/TAXIS trial (ClinicalTrials.gov Identifier: NCT03513614) to include the first 500 randomized patients with confirmed nodal disease at the time of surgery. The TAXIS study's pragmatic design allowed both the neoadjuvant and adjuvant setting according to the preferences of the local investigators who were encouraged to register eligible patients consecutively. RESULTS: A total of 500 patients were included at 44 breast centers in six European countries from August 2018 to June 2022, 165 (33%) of whom underwent NST. Median age was 57 years (interquartile range [IQR], 48-69). Most patients were postmenopausal (68.4%) with grade 2 and 3 hormonal receptor-positive and human epidermal growth factor receptor 2-negative breast cancer with a median tumor size of 28 mm (IQR 20-40). The use of NST varied significantly across the countries (p < 0.001). Austria (55.2%) and Switzerland (35.8%) had the highest percentage of patients undergoing NST and Hungary (18.2%) the lowest. The administration of NST increased significantly over the years (OR 1.42; p < 0.001) and more than doubled from 20 to 46.7% between 2018 and 2022. CONCLUSION: Substantial heterogeneity in the use of NST with HR+/HER2-breast cancer exists in Europe. While stringent guidelines are available for its use in triple-negative and HER2+ breast cancer, there is a need for the development of and adherence to well-defined recommendations for HR+/HER2-breast cancer.

RESUMO

AIM OF THE STUDY: The arsenal of questions and answers about the minor cancer initiating cancer stem cell (CSC) population put responsible for cancer invasiveness and metastases, has left with an unsolved puzzle. Specific aims of a complex project were partly focused on revealing new biomarkers of cancer. We designed and set up novel techniques to facilitate the detection of cancerous cells. MATERIALS AND METHODS: As a novel approach, we investigated B cells infiltrating breast carcinomas and melanomas (TIL-B) in terms of their tumour antigen binding potential. By developing the TIL-B phage display technology we provide here a new technology for the specific detection of highly tumour-associated antigens. Single chain Fv (scFv) antibody fragment phage ELISA, immunofluorescence (IF) FACS analysis, chamber slide technique with IF confocal laser microscopy and immunohistochemistry (IHC) in paraffin-embedded tissue sections were set up and standardized. RESULTS: We showed strong tumour-associated disialylated glycosphingolipid expression levels on various cancer cells using scFv antibody fragments, generated previously by uniquely invasive breast carcinoma TIL-B phage display library technology. CONCLUSIONS: We report herein a novel strategy to obtain antibody fragments of human origin that recognise tumour-associated ganglioside antigens. Our investigations have the power to detect privileged molecules in cancer progression, invasiveness, and metastases. The technical achievements of this study are being harnessed for early diagnostics and effective cancer therapeutics.

RESUMO

Background We examined time trends in axilla management among patients with early breast cancer in European clinical settings. Material and methods EUROCANPlatform partners, including population-based and cancer center-specific registries, provided routinely available clinical cancer registry data for a comparative study of axillary management trends among patients with first non-metastatic breast cancer who were not selected for neoadjuvant therapy during the last decade. We used an additional short questionnaire to compare clinical care patterns in 2014. Results Patients treated in cancer centers were younger than population-based registry populations. Tumor size and lymph node status distributions varied little between settings or over time. In 2003, sentinel lymph node biopsy (SLNB) use varied between 26% and 81% for pT1 tumors, and between 2% and 68% for pT2 tumors. By 2010, SLNB use increased to 79-96% and 49-92% for pT1 and pT2 tumors, respectively. Axillary lymph node dissection (ALND) use for pT1 tumors decreased from between 75% and 27% in 2003 to 47% and 12% in 2010, and from between 90% and 55% to 79% and 19% for pT2 tumors, respectively. In 2014, important differences in axillary management existed for patients with micrometastases only, and for patients fulfilling the ACOSOG Z0011 criteria for omitting ALND. Conclusion This study demonstrates persisting differences in important aspects of axillary management throughout the recent decade. The results highlight the need for international comparative patterns of care studies in oncology, which may help to identify areas where further studies and consensus building may be necessary.

RESUMO

INTRODUCTION: Immediate breast reconstruction provides oncological safety, requires longer operation time. It does not influence the initiation of adjuvant therapy and radiological control, and results in favourable cosmetic outcome. AIM: Assessing the Hungarian data of immediate postmastectomy breast reconstructions, and comparing them to international findings. METHOD: Between May, 2011 and September, 2014 121 therapeutic and prophylactic, postmastectomy immediate breast reconstructions were performed in 100 patients. The clinico-pathological findings were assessed retrospectively, and surgical, oncological and cosmetic outcomes were evaluated statistically. RESULTS: The mean age of patients was 42.6 years, the follow up time was 29.4 months, and the duration of operation was 132 minutes. Skin-sparing mastectomy was performed most commonly (64%) with submuscular tissue expander placement (70%). Early postoperative complication was identified in 18 patients, and loco-regional recurrence in 1 patient. Most patients (89%) were satisfied with the cosmetic outcome. The average initiation time of adjuvant therapy was 4.8 weeks. CONCLUSIONS: Immediate breast reconstruction is a safe and effective option in line with international findings. Orv.

RESUMO

INTRODUCTION: The European Society of Breast Cancer Specialists has created quality indicators for breast units to establish minimum standards and to ensure specialist multimodality care with the conscious aim of improving outcomes and decreasing breast cancer mortality. AIM: The aim of this study was to analyse the breast cancer care in the National Institute of Oncology according to the European Society of Breast Cancer Specialists requirements and in a large number of cases in order to present representative clinico-pathological data on the incidence of breast cancer in Hungary. METHOD: According to the European Society of Breast Cancer Specialists uniformed criteria clinico-pathological data of multimodality treated breast cancer cases were retrospectively analysed between June 1, 2011 and May 31, 2012. RESULTS: During the period of interest 906 patients underwent breast surgery for malignant or benign lesions. According to the European Society of Breast Cancer Specialists quality indicators the breast cancer care of the National Institute of Oncology is eligible. CONCLUSIONS: The diagnostic modalities and multimodality care of breast cancer of the National Institute of Oncology breast unit meets the critical mass and minimum standards of the European Society of Breast Cancer Specialists criteria.

RESUMO

BACKGROUND: According to European guidelines, breast cancer patients requiring mastectomy should be informed about available options regarding breast reconstruction. There are clear differences in the quality standards of oncoplastic care throughout Europe, with slight improvements in Central European countries like Hungary. The aim of the present investigation was to evaluate patients' knowledge and demand for postmastectomy breast reconstruction, as well as their psychosocial background regarding decision-making. MATERIAL AND METHODS: A questionnaire containing 15 structured questions was given to 500 breast cancer patients on the day before undergoing mastectomy. The questions focused on the emotional impact of the malignant disease and the loss of a breast; the importance of environmental conditions; the desire for breast reconstruction; and patients' knowledge and sources of information about the procedure. All answers were statistically analyzed in the context of patient age, marital status, educational level, and place of residence. RESULTS: Descriptive statistical results of the answers to all questions, as well as associations of the different aspects of the decision-making process, are presented. CONCLUSIONS: Hungarian breast cancer patients have very limited knowledge regarding breast reconstruction. We confirmed that patients scheduled for mastectomy have a great degree of anxiety due to their disease and breast loss. Almost 50% of the responders declared their desire for postmastectomy breast reconstruction. Patient's age, residence, educational level, marital status, and profession were confirmed as predictive factors in the decision-making process for breast reconstruction.

RESUMO

Skin- and nipple-sparing mastectomies made immediate breast reconstruction possible on a systemic level within breast cancer surgery. Mass reconstruction needs brought by the most common malignancy in women can only be met by the use of implant-based techniques, providing excellent cosmetic results and high patient satisfaction. For these postmastectomy reconstructions the replacement of the skin is no longer a challenge, but the well vascularized, good quality soft tissue coverage of the implant. Oncoplastic breast surgery today is able to conduct oncologically radical complete removal of the glandular tissue through an incision of 6-10 cm made in the armpit, with the nearly scarless retention of the natural skin envelope of the breast, and in the same time adequate axillary staging (sentinel node biopsy/axillary lymphadenectomy) is performed, then using the same incision, the implementation of one-step or multi-step breast reconstruction is possible. During these complex interventions, the latissimus dorsi flap formed by endoscopic technique (leaving no scar on the back), rotated to the anterior chest wall can be used for total autologous reconstruction of low-volume breasts as complete coverage of implants placed under the spared skin-envelope or for revitalization of thin or radiation damaged breast skin. This paper presents 4 cases of breast reconstruction with endoscopically assisted latissimus dorsi muscle flap, and the authors demonstrate the surgical technique in detail and conduct a literature review, for the first time in Hungarian.

RESUMO

Due to the development in medical science and industrial technology, minimally invasive procedures have appeared in the surgery of benign and malignant breast diseases. In general , such interventions result in significantly reduced breast and chest wall scars, shorter hospitalization and less pain, but they require specific, expensive devices, longer surgical time compared to open surgery. Furthermore, indications or oncological safety have not been established yet. It is quite likely, that minimally invasive surgical procedures with high-tech devices - similar to other surgical subspecialties -, will gradually become popular and it may form part of routine breast surgery even. Vacuum-assisted core biopsy with a therapeutic indication is suitable for the removal of benign fibroadenomas leaving behind an almost invisible scar, while endoscopically assisted skin-sparing and nipple-sparing mastectomy, axillary staging and reconstruction with latissimus dorsi muscle flap are all feasible through the same short axillary incision. Endoscopic techniques are also suitable for the diagnostics and treatment of intracapsular complications of implant-based breast reconstructions (intracapsular fluid, implant rupture, capsular contracture) and for the biopsy of intracapsular lesions with uncertain pathology. Perception of the role of radiofrequency ablation of breast tumors requires further hands-on experience, but it is likely that it can serve as a replacement of surgical removal in a portion of primary tumors in the future due to the development in functional imaging and anticancer drugs. With the reduction of the price of ductoscopes routine examination of the ductal branch system, guided microdochectomy and targeted surgical removal of terminal ducto-lobular units or a "sick lobe" as an anatomical unit may become feasible. The paper presents the experience of the authors and provides a literature review, for the first time in Hungarian language on the subject. Orv. Hetil., 2014, 155(5), 162-169.

RESUMO

Metaplastic breast tumour is a rare, aggressive, mostly triple- negative, dedifferentiated malignancy, which poorly responds to chemotherapy compared to other invasive breast tumours. Since 2000, the WHO has considered it as a separate entity among breast tumours. Given the extremely poor prognosis of the tumour, more studies are needed to establish the most effective treatment strategy supported by data to increase overall survival. The objective of our research was a retrospective analysis of 77 patients with metaplastic breast cancer treated between 01.01.2012 and 28.02.2023 at our institute. Following the descriptive statistics of the patients, the pathological or clinical response was examined in cases of 15 patients treated with neoadjuvant and 14 patients with palliative chemotherapy. Finally, we compared the overall and progression-free survival of metaplastic breast cancer patients treated at our institute with those described in the international literature. The research results, both at our institute and in the literature, are limited by the small number of cases. In our research, with similar numbers of cases as many other investigations, we obtained results close to international data, thereby supporting the collection of data and further research necessary for the most effective treatment strategy for this rare tumour.

RESUMO

BACKGROUND: The use of the Oncotype DX test reduces the rate of adjuvant chemotherapy recommendations. Few in-depth analyses have been performed on this decision-making process. METHODS: We retrospectively analyzed patient data based on available Oncotype DX test results (RS) irrespective of nodal status at a single center. We collected recommendations from six oncologists, first without RS (pre-RS) and then with RS results (post-RS). We investigated changes in recommendations, agreement between oncologist decisions, and the effect of different National Comprehensive Cancer Network (NCCN) recommendation categories (for, against, and considering chemotherapy). RESULTS: Data from 201 patients were included in the analysis. Recommendation of chemotherapy decreased by an average of 39.5%. Agreement improved substantially with RS, with a kappa value pre-RS of 0.37 (fair agreement) and post-RS of 0.75 (substantial agreement). Discordance remained substantial in cases where the NCCN recommendations considered chemotherapy only (32%). Pre-RS consensus against chemotherapy predicted low RS results (50 out of 51 patients). Post-RS consensus was highest in the NCCN chemotherapy recommendation group. CONCLUSIONS: The Oncotype DX test substantially improves decision accuracy in recommending adjuvant chemotherapy. It may be further improved with a consensus decision. In the case of pre-RS consensus against chemotherapy, the test can be spared.

RESUMO

The incidence of pregnancy-associated breast cancer is rising. Sentinel lymph node biopsy is the method of choice in clinically node negative cases as the indicated minimally invasive regional staging procedure. Some reports have linked radioisotope and blue dye required for lymphatic mapping to teratogenic effects, the idea of which has become a generalized statement and, until recently, contraindication for these agents was considered during pregnancy. Today, there are many published reports of successful interventions with low-dose 99mTc-labeled human albumin nanocolloid, based on dosimetric modeling demonstrating a negligible radiation exposure of the fetus. These results contributed to the seemingly safe and successful use of sentinel lymph node biopsy during pregnancy, though generally it can not replace axillary lymphadenectomy in the absence of high-quality evidence. The possibility of sentinel lymph node biopsy should be offered to pregnancy-associated early breast cancer patients with clinically negative axilla, and patients should be involved in the decision making following extensive counselling. This paper presents the successful use of sentinel lymph node biopsy with low-dose tracer during two pregnancies (in the first and third trimesters) and, for the first time in Hungarian language, it offers a comprehensive literature review on this topic.

RESUMO

INTRODUCTION: Sentinel lymph node biopsy alone has become an acceptable alternative to elective axillary lymph node dissection in patients with clinically node-negative early-stage breast cancer. Approximately 70 percent of the patients undergoing breast surgery develop side effects caused by the axillary lymph node dissection (axillary pain, shoulder stiffness, lymphedema and paresthesias). AIM: The current standard treatment is to perform completion axillary lymph node dissection in patients with positive sentinel lymph node biopsy. However, randomized clinical trials of axillary dissection versus axillary irradiation failed to show survival differences between the two types of axillary treatment. The National Institute of Oncology, Budapest conducted a single centre randomized clinical study. The OTOASOR (Optimal Treatment of the Axilla - Surgery or Radiotherapy) trial compares completion axillary lymph node dissection to axillary nodal irradiation in patients with sentinel lymph node-positive primary invasive breast cancer. METHOD: Patients with primary invasive breast cancer (clinically lymph node negative and less than or equal to 3 cm in size) were randomized before surgery for completion axillary lymph node dissection (arm A-standard treatment) or axillary nodal irradiation (arm B-investigational treatment). Sentinel lymph node biopsy was performed by the radio-guided method. The use of blue-dye was optional. Sentinel lymph nodes were investigated with serial sectioning at 0.5 mm levels by haematoxylin and eosin staining. In the investigational treatment arm patients received 50Gy axillary nodal irradiation instead of completion axillary lymph node dissection. Adjuvant treatment was recommended and patients were followed up according to the actual institutional guidelines. RESULTS: Between August 2002 and June 2009, 2106 patients were randomized for completion axillary lymph node dissection (1054 patients) or axillary nodal irradiation (1052 patients). The two arms were well balanced according to the majority of main prognostic factors. Sentinel lymph node was identified in 2073 patients (98.4%) and was positive in 526 patients (25.4%). Fifty-two sentinel lymph node-positive patients were excluded from the study (protocol violation, patient's preference). Out of the remaining 474 patients, 244 underwent completion axillary lymph node dissection and 230 received axillary nodal irradiation according to randomization. The mean length of follow-up to the first event and the mean total length of follow-up were 41.9 and 43.3 months, respectively, and there were no significant differences between the two arms. There was no significant difference in axillary recurrence between the two arms (0.82% in arm A and 1.3% in arm B). There was also no significant difference in terms of overall survival between the arms at the early stage follow-up. CONCLUSIONS: The authors conclude that after a mean follow-up of more than 40 months axillary nodal irradiation may control the disease in the axilla as effectively as completion axillary lymph node dissection and there was also no difference in terms of overall survival.

A korai és lokálisan elorehaladott colontumorok esetében a megfelelo onkológiai minoségu sebészi resectio a kezelés központi eleme. Jobb oldali vastagbél tumorok sebészi ellátásában - a kedvezobb hosszú távú onkológiai eredmények elérése céljából - egyre szélesebb körben elfogadott a Hohenberger által 2009-ben elsoként publikált "complett mesocolicus-excisio" (CME) és centrális érlekötés (CVL).Esetünkben egy 78 éves nobeteg jobb alhasi faeculens váladékozása miatt indult kivizsgálása során a hasfalat szélesen infiltráló coecum tumor igazolódott. Az Onkoterápiás Bizottság - tekintettel az egyértelmu távoli áttét hiányára, a beteg jó általános állapotára, a fennálló colo-cutan sipolyra és egyértelmu irresecabilitási jelek hiányára - mutétet javasolt. A kuratív intenció és kello radikalitás érdekében, komplett mesocolicus excisio és kiterjesztett hasfali resectio mellett döntöttünk. A mutét során a kialakult hasfali defektus rekonstrukciójához a jobb comb lateralis felszínérol tensor fasciae lateae musculocutan (TFL) lebenyt preparáltunk. A hasfali defektust, mind a fascia, mind a subcutis-cutis rétegében helyreállítottuk, a donor területet primeren zártuk. A posztoperatívumban a lebeny distalis végén vénás pangás jelei majd felületes necrosis mutatkozott.

RESUMO

Importance: The role of axillary lymph node dissection (ALND) to determine nodal burden to inform systemic therapy recommendations in patients with clinically node (cN)-positive breast cancer (BC) is currently unknown. Objective: To address the association of ALND with systemic therapy in cN-positive BC in the upfront surgery setting and after neoadjuvant chemotherapy (NACT). Design, Setting, and Participants: This was a prospective, observational, cohort study conducted from August 2018 to June 2022. This was a preplanned study within the phase 3 randomized clinical OPBC-03/TAXIS trial. Included were patients with confirmed cN-positive BC from 44 private, public, and academic breast centers in 6 European countries. After NACT, residual nodal disease was mandatory, and a minimum follow-up of 2 months was required. Exposures: All patients underwent tailored axillary surgery (TAS) followed by ALND or axillary radiotherapy (ART) according to TAXIS randomization. TAS removed suspicious palpable and sentinel nodes, whereas imaging-guidance was optional. Systemic therapy recommendations were at the discretion of the local investigators. Results: A total of 500 patients (median [IQR] age, 57 [48-69] years; 487 female [97.4%]) were included in the study. In the upfront surgery setting, 296 of 335 patients (88.4%) had hormone receptor (HR)-positive and Erb-B2 receptor tyrosine kinase 2 (ERBB2; formerly HER2 or HER2/neu)-negative disease: 145 (49.0%) underwent ART, and 151 (51.0%) underwent ALND. The median (IQR) number of removed positive lymph nodes without ALND was 3 (1-4) nodes compared with 4 (2-9) nodes with ALND. There was no association of ALND with the proportion of patients undergoing adjuvant chemotherapy (81 of 145 [55.9%] vs 91 of 151 [60.3%]; adjusted odds ratio [aOR], 0.72; 95% CI, 0.19-2.67) and type of systemic therapy. Of 151 patients with NACT, 74 (51.0%) underwent ART, and 77 (49.0%) underwent ALND. The ratio of removed to positive nodes was a median (IQR) of 4 (3-7) nodes to 2 (1-3) nodes and 15 (12-19) nodes to 2 (1-5) nodes in the ART and ALND groups, respectively. There was no observed association of ALND with the proportion of patients undergoing postneoadjuvant systemic therapy (57 of 74 [77.0%] vs 55 of 77 [71.4%]; aOR, 0.86; 95% CI, 0.43-1.70), type of postneoadjuvant chemotherapy (eg, capecitabine: 10 of 74 [13.5%] vs 10 of 77 [13.0%]; trastuzumab emtansine-DM1: 9 of 74 [12.2%] vs 11 of 77 [14.3%]), or endocrine therapy (eg, aromatase inhibitors: 41 of 74 [55.4%] vs 36 of 77 [46.8%]; tamoxifen: 8 of 74 [10.8%] vs 6 of 77 [7.8%]). Conclusion: Results of this cohort study suggest that patients without ALND were significantly understaged. However, ALND did not inform systemic therapy recommendations.

RESUMO

The authors present the diverse etiology of nipple discharge, which background may be a tumor. They discuss the checkup ways of nipple discharge and review in detail the galactographic technique and evaluation. The examination of pathologic nipple discharge is essentially based on contact cytology, x-ray-, and ultrasound mammography. Consequently, galactography is applied by filling the ducts with contrast material. The final diagnosis is rendered by histologic examination, following the operation. The authors demonstrate the application and role of galactography through various cases.

RESUMO

The purpose of our work was to evaluate the efficacy of second breast-conserving surgery (BCS) and reirradiation with interstitial high-dose-rate (HDR) brachytherapy (BT) for the management of local recurrences. Between 1999 and 2010, fifteen patients initially treated for breast carcinoma by BCS and radiation therapy who had isolated intra-breast recurrence underwent second BCS and perioperative HDR multicatheter BT. Breast cancer related events, late side effects, and cosmetic results were assessed. At a median follow-up of 62 months (range: 11-127) second local recurrence has not occurred, yielding a 100% mastectomy-free survival. Four patients (27%) developed subsequent distant metastasis and died of breast cancer. The 5-year actuarial rate of disease-free and overall survival was 69% and 85%, respectively. Cosmetic results were rated excellent, good, fair, poor, and unknown in 1 (7%), 10 (66%), 2 (13%), 1 (7%), and 1 (7%) patients, respectively. Grade 2 fibrosis and skin toxicity occurred in 1 (7%) and 1 (7%) patients. Asymptomatic fat necrosis was detected in 9 (60%) women. No patient developed grade 3-4 late side effects. Second BCS followed by partial breast reirradiation is a safe and effective option for the management of selected patients developing intra-breast recurrence after previous breast-conserving therapy. Perioperative HDR BT may decrease the risk of second local relapse with acceptable cosmetic results and low rate of late side effects.

RESUMO

The uniform European structure and professional standards for high quality breast cancer care were established in conjunction with the European Organisation for Research and Treatment, the European Society of Mastology and the European Breast Cancer Coalition with the support of the European Parliament. Well-prepared professional teams including a new member called the breast care nurse serve as ground for special breast cancer centers with international accreditation that provide modern, evidence based, patient centered multidisciplinary oncological care. The responsibilities of the new qualified professional staff member include the psycho-social support of the patient and carers from the moment of diagnosis throughout the whole oncological treatment, the fostering of delivering information and communication between patients and specialists. As a result of the curriculum founded by the European Oncology Nursing Society, breast care nurses have become key members of the practice of holistic breast cancer care in countries where the European recommendations have already been implemented. Considering the expected rearrangement of national oncological care, the new sub-specialty is outlined for the first time in the light of the experiences gained at the National Institute of Oncology, Budapest, a comprehensive cancer center.
