Sentinel lymph node biopsy following previous axillary surgery in recurrent breast cancer.

INTRODUCTION: Ipsilateral breast recurrence or second primary breast cancer can develop in patients who have undergone breast conserving surgery (BCS) and axillary surgery. The purpose of this study was to examine the feasibility of a reoperative sentinel lymph node biopsy (SLNB) as a repeated axillary staging procedure. PATIENTS AND METHODS: From August 2014 through January 2017 patients with locally recurrent breast cancer or with BRCA mutation requiring risk reduction mastectomy as a second surgical procedure, underwent repeat SLNB in three Hungarian Breast Units with a radiocolloid (and blue dye) technique. RESULTS: Hundred and sixty repeat SLNBs were analysed, 80 after previous SLNB and 80 after previous total or partial axillary lymph node dissection (ALND). SLN identification was successful in 106 patients (66%); 77/80 (77.5%) and 44/80 (55%) in the SLNB and ALND groups, respectively. (p < 0.003). Extra-axillary lymph drainage was more frequent in the ALND group (19/44, 43,2% versus 7/62, 11,3%; p < 0.001). Lymphatic drainage to the contralateral axilla was observed in 14 patients (11 in the ALND group, p = 0.025), isolated parasternal drainage was detected in 4 patients (p = 0.31). Only 9/106 patients with successful repeat SLNB (8,8%, all with 1 SLN removed) had SLN metastases CONCLUSIONS: Repeat SLNB is feasible in patients with ipsilateral breast tumor recurrence or new ipsilateral primary tumor after previous BCS and axillary staging. Repeat SLNB should replace routine ALND as the standard axillary restaging procedure in recurrent disease with a clinically negative axilla. Preoperative lymphoscintigraphy is important to explore extra-axillary lymphatic drainage in this restaging setting.

Eight-year follow up result of the OTOASOR trial: The Optimal Treatment Of the Axilla - Surgery Or Radiotherapy after positive sentinel lymph node biopsy in early-stage breast cancer: A randomized, single centre, phase III, non-inferiority trial.

INTRODUCTION: 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 of axillary lymph node dissection (cALND) to regional nodal irradiation (RNI) in patients with sentinel lymph node metastasis (pN1sn) in stage I-II breast cancer. PATIENTS AND METHODS: Patients with primary invasive breast cancer (cN0 and cT ≤ 3 cm) were randomized before surgery for cALND (standard treatment) or RNI (investigational treatment). Sentinel lymph nodes (SN) were investigated with serial sectioning at 0.5 mm levels by hematoxylin-eosin staining. Investigational treatment arm patients received 50 Gy RNI instead of cALND. Adjuvant treatment and follow up were performed according to the actual guidelines. Between August 2002 and June 2009, 1054 patients were randomized for cALND and 1052 patients for RNI. SN was evaluated in 2073 patients and was positive in 526 patients (25.4%). 474 cases were evaluable (244 in the cALND and 230 in the RNI arm), and in the cALND group 94 of 244 patients (38.5%) who underwent completion axillary surgery has additional positive nodes. The two arms were well balanced according to the majority of main prognostic factors. Primary endpoint was axillary recurrence and secondary endpoints were overall survival (OS) and disease-free survival (DFS). RESULTS: Mean follow-up was 97 months (Q1-Q3: 80-120). Axillary recurrence was 2.0% in cALND arm vs. 1.7% in RNI arm (p = 1.00). OS at 8 years was 77.9% vs. 84.8% (p = 0.060), and DFS was 72.1% in cALND arm and 77.4% after RNI (p = 0.51). The results show that RNI is statistically not inferior to cALND treatment. CONCLUSIONS: The long term follow-up results of this prospective-randomized trial suggest that RNI without cALND does not increase the risk of axillary failure in selected patients with early-stage invasive breast cancer (cT ≤ 3 cm, cN0) and pN1(sn). Axillary radiotherapy should be an alternative treatment for selected patients with sentinel lymph node metastases.

Clinical experiences with the use of ULTRAPRO® mesh in single-stage direct-to-implant immediate postmastectomy breast reconstruction in 102 patients: A retrospective cohort study.

BACKGROUND: Acellular dermal matrices have been used for direct-to-implant (DTI) breast reconstruction (BR), eliminating the load of the lower pole skin envelope. However, the available allograft matrices add considerable health care costs. This study examined the long-term follow-up of synthetic ULTRAPRO® mesh as a low-cost potential alternative to biological matrices. PATIENTS AND METHODS: A retrospective cohort study was performed between January 2013 and January 2016, involved 112 early-stage breast cancer and/or BRCA 1/2 patients, and evaluated 189 immediate DTI BRs following skin-, areola- or nipple-sparing mastectomy using ULTRAPRO® mesh. Patient characteristics and postoperative complications were recorded, and quality of life was rated by the patients using the EORTC-QLQ-C30-BR23 questionnaire. Aesthetic outcomes and palpability of the implants were evaluated by four breast surgeons on a 5-point Likert scale. All recorded parameters were statistically analysed. RESULTS: Ten patients were lost-to-follow-up, resulting in 102 patients and 174 breast surgery cases analysed. The mean age was 43 years, with 23.4 months of follow-up on average. Forty-six patients (45.1%) had previous radiotherapy with pre-existing scars. In total, 32 complications (18.3%) were recorded, including 12 minor (6.9%) and 20 major (11.4%) complications requiring revision. All median quality of life scores were above 83 points, representing a high score, with an average 4-point rating for the aesthetic outcome and natural consistency of the breast. CONCLUSION: Partially absorbable ULTRAPRO® mesh could be used successfully in DTI BR, offering a safe, less expensive alternative to biological matrices. Adequate indications and patient selection are necessary.

Objective decision making between conventional and oncoplastic breast-conserving surgery or mastectomy: An aesthetic and functional prospective cohort study.

BACKGROUND: Breast-conserving surgery (BCS) is considered the standard treatment for early-stage breast cancer. However, fair to poor cosmetic outcomes following conventional BCS have been observed in as many as one-third of cases. The aim of this study was to determine the critical tumor-to-breast volume ratio for each quadrant of the breast beyond which conventional BCS would no longer offer acceptable cosmetic and functional results or satisfactory quality of life for the patient. METHODS: A prospective cohort study was performed between December 2011 and December 2013 involving 350 patients younger than 70 years with early-stage unifocal (T ≤ 30 mm) breast cancer who underwent wide excision and axillary sentinel lymph node biopsy followed by whole-breast irradiation. Using validated panels and software (the Breast Cancer Treatment Outcome Scale [BCTOS], EORTC Cancer Quality of Life Questionnaire number C30-BR23, and Breast Cancer Conservative Treatment - cosmetic results [BCCT.core] software), quality of life and aesthetic and functional parameters and their changes in correlation to the percentage of breast volume excised were statistically analyzed. RESULTS: The maximum percentages of breast volume that were resectable by conventional BCS without resulting in unacceptable aesthetic and functional outcomes or decreased quality of life were 18-19% in the upper-outer quadrant (p < 0.0001), 14-15% in the lower-outer quadrant (p < 0.0001), 8-9% in the upper-inner quadrant (p < 0.0001), and 9-10% in the lower-inner quadrant (p < 0.0001). CONCLUSION: Aided by the calculated cut-off values for each breast quadrant, breast surgeons might render more objective decisions regarding performing conventional BCS, using oncoplastic techniques or choosing mastectomy with immediate reconstruction.

Does breast screening offer a survival benefit? A retrospective comparative study of oncological outcomes of screen-detected and symptomatic early stage breast cancer cases.

INTRODUCTION: Mammography screening reduces breast cancer mortality by up to 32%. However, some recent studies have questioned the impact of non-palpable breast cancer detection on mortality reduction. The aim of this study was to analyse the clinicopathological and long-term follow-up data of early stage screened and symptomatic breast cancer patients. PATIENTS AND METHOD: The institutional prospectively led database was systematically analysed for breast cancer cases diagnosed via the mammography screening program from 2002 to 2009. As a control group, symptomatic early stage breast cancer patients were collected randomly from the same database and matched for age and follow-up period. All medical records were reviewed retrospectively. RESULTS: Data from 298 breast cancer patients were collected from 47,718 mammography screenings. In addition, 331 symptomatic breast cancer patients were randomly selected. The screened group presented a significantly lower median tumour size (P < 0.00001). The incidence of negative regional lymph nodes was significantly higher in the screened group (P < 0.0006). The incidence of chemotherapy was 17% higher in the symptomatic group (P = 4*10-5). At the median follow-up of 65 and 80 months, the screened group did not exhibit better overall (P = 0.717) or disease-free survival (P = 0.081) compared to the symptomatic group. CONCLUSION: Our results do not suggest that mammography screening does not reduce breast cancer mortality but the mammography screening did not bring any significant improvement in patient overall or disease-free survival for the early stage breast cancer patients compared to the symptomatic group. The drawback of symptomatic early stage tumours compared to non-palpable tumours could be equalized by modern multimodality oncology treatments.

An International Multicenter Review of the Malignancy Rate of Excised Papillomatous Breast Lesions.

BACKGROUND: Papillary lesions of the breast are a relatively rare, but heterogeneous group ranging from benign to atypical and malignant. Debate exists regarding the optimal management of these lesions. In the absence of more accurate risk-stratification models, traditional management guidelines recommend surgical excision, despite the majority of lesions proving benign. This study sought to determine the rate of malignancy in excised breast papillomas and to elucidate whether there exists a population in which surgical excision may be unnecessary. METHODS: A multicenter international retrospective review of core biopsy diagnosed breast papillomas and papillary lesions was performed between 2009 and 2013, following institutional ethical approval. Patient demographics, histopathological, and radiological findings were recorded. All data was tabulated, and statistical analysis performed using Stata. RESULTS: A total of 238 patients were included in the final analysis. The age profile of those with benign pathology was significantly younger than those with malignant pathology (p < 0.001). Atypia on core needle biopsy was significantly associated with a final pathological diagnosis of malignancy (OR = 2.73). The upgrade rate from benign core needle biopsy to malignancy on the final pathological sample was 14.4 %; however, only 3.7 % had invasive cancer. CONCLUSIONS: This international dataset is one of the largest in the published literature relating to breast papillomas. The overall risk of malignancy is significantly associated with older age and the presence of atypia on core needle biopsy. It may be possible to stratify higher-risk patients according to age and core needle biopsy findings, thereby avoiding surgery on low-risk patients.

Bilateral juvenile fibroadenosis of the breast: management with subcutaneous mastectomy and silicone implant placement.

Bilateral fibroadenosis is a rare, benign disorder, affecting adolescents or women of childbearing age. Choosing the most optimal therapy that manages both the physical and psychological aspects of the disease is a challenge. The goals of the treatment are complete resection of the lesions with optimal cosmesis. Options range from cryoablation, ultrasound-guided vacuum-assisted eradication and simple excision of the lesions to subcutaneous mastectomy with reconstruction. We present a case of a 25-year-old woman with 37 complex fibroadenomas affecting both breasts who was treated with nipple-sparing subcutaneous mastectomy and silicone implant reconstruction to both the surgeons' and patient's satisfaction.

Granular cell tumour of the breast: case series and review of the literature.

Granular cell tumours (GCTs) are uncommon rare neoplasms that may occur in any part of the body. Approximately 5-8% of granular cell tumours occur within the breast. Although nearly always benign in behaviour, granular cell tumours of the breast can often mimic breast malignancies both clinically and on the basis of imaging techniques. This article reports five cases of benign granular cell tumours appearing in the breast, mimicking a malignant breast lesion. In addition to reporting the cases, the relevant literature was reviewed.

[T-cell large granular lymphocytic leukemia associated with pure red cell aplasia, successfully treated with cyclophosphamide]. / T-sejtes, nagy granuláris lymphocyta leukaemiához társuló "pure red cell aplasia" eredményes kezelése cyclophosphamiddal.

Authors report effective treatment of T-cell large granular lymphocyte (LGL) leukaemia and secondary pure cell aplasia with cyclophosphamide. The current classification of LGL proliferations is presented, with emphasis on the issues of diagnosis, clinical course and treatment. LGL proliferations are not so rare that previously thought and should be involved in the differential diagnosis of neutropenia, pure red cell aplasia, Felty's syndrome and vasculitis of unknown origin.
