Outcome of Management of Local Recurrence after Immediate Transverse Rectus Abdominis Myocutaneous Flap Breast Reconstruction

BackgroundNo consensus has been reached regarding the outcome of management of local recurrence after transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction. This study demonstrated the presentation, management, and outcomes of local recurrence after immediate TRAM breast reconstruction.MethodsA comparison was conducted among 1,000 consecutive patients who underwent immediate breast reconstruction with a pedicled TRAM flap (TRAM group) and 3,183 consecutive patients who underwent only modified radical mastectomy without reconstruction (MRM group) from January 2001 to December 2009. The presentation, treatment, and outcome including aesthetics and overall survival rate were analyzed.ResultsLocal recurrences occurred in 18 (1.8%) patients (TRAM-LR group) who underwent TRAM breast reconstruction and 38 (1.2%) patients (MRM-LR group) who underwent MRM only (P=0.1712). Wide excision was indicated in almost all the local recurrence cases. Skin graft was required in 4 patients in the MRM-LR group, whereas only one patient required a skin graft to preserve the mound shape in the TRAM-LR group. The breast mound was maintained in all 17 patients that survived in the TRAM-LR group even after wide excision. The overall survival rate was 94.4% in the TRAM-LR group and 65.8% in the MRM-LR group (P=0.276).ConclusionsLocal recurrence after immediate TRAM flap breast reconstruction could be detected without delay and managed effectively by multiple modalities without reducing overall survival rates. Breast mound reconstruction with soft autologous tissue allowed for primary closure in most of the cases. In all of the patients who survived, the contour of their reconstructed breast remained

Erratum: Nation-Wide Korean Breast Cancer Data from 2008 Using the Breast Cancer Registration Program

nation-wide breast cancer data and analyzed the data using their online registration program biannually. The purpose of this study was to evaluate the characteristics of Korean breast cancer from 2008 and examine chronological based patterns. Methods: Data were collected from 38 medical schools (67 hospitals), 20 general hospitals, and 10 private clinics. The data on the total number, gender, and age distribution were collected through a questionnaire as well as other detailed data analyzed via the online registration program. Results: In 2008, there were 13,908 patients who were newly diagnosed with breast cancer. The crude incidence rate of female breast cancer was 57.3 among 100,000 and the median age was 49 years. The age distribution had not changed since the initial survey; however the proportion of postmenopausal patients had increased and median age was older than the past. In staging distribution, the proportion of early breast cancer (stage 0, I) was 47.2 % with, breast-conserving surgery performed in 58 % and mastectomy in 39.5%. Conclusion: Compared to past data, the incidence of breast cancer in Korea continues to rise. Furthermore, the proportion of those detected by screening and breast conservation surgery has increased remarkably. To understand the patterns of Korean breast cancer, the nation-wide data should continuously investigated

Capecitabine and Vinorelbine in Patients with Metastatic Breast Cancer Previously Treated with Anthracycline and Taxane

We have evaluated the efficacy and safety of the combination of capecitabine and vinorelbine in metastatic breast cancer (MBC) patients previously treated with anthracycline-and taxane-containing regimens. Between April 2000 and September 2002, 44 female MBC patients received oral capecitabine (1,250 mg/m2 twice daily on days 114), and intravenous vinorelbine (25 mg/m2 on days 1 and 8) during each 3 week-chemotherapy cycle (median, 5 cycles/patient; total, 235 cycles). One patient achieved a complete response and 21 patients had partial responses, giving an overall response rate of 50% in the intention-to-treat analysis (95% CI, 35.0-65.0%). Median duration of response was 6.0 months (range 1.2-23.0 months). Patients were followed-up for a median of 16 months, with median progression-free survival being 5.3 months, and median overall survival being 17 months. Toxicities included grades III and IV neutropenia in 63 (26.8%) and 4 (1.7%) cycles, respectively, and grades II and III hand-foot syndrome in 12 (5.1%) and 4 (1.7%) cycles, respectively. Other nonhematologic toxicities were minimal and manageable. In conclusion, the combination of capecitabine and vinorelbine was effective and well tolerated in MBC patients even after treatment with anthracyclines and taxanes

Efficacy of neoadjuvant endocrine therapy compared with neoadjuvant chemotherapy in pre-menopausal patients with oestrogen receptor-positive and HER2-negative, lymph node-positive breast cancer

Introduction Neoadjuvant endocrine therapy (NET) has demonstrated efficacy in post-menopausal patients with hormone-responsive breast cancer. This trial was designed to compare the efficacy of neoadjuvant chemotherapy (NCT) with NET in pre-menopausal breast cancer. Patients and methods In this prospective, randomised, phase III study, oestrogen receptor (ER)-positive, HER2-negative, and lymph node-positive pre-menopausal breast cancer patients were recruited from 7 hospitals in South Korea. Enrolled patients were randomly assigned (1:1) to receive 24 weeks of either NCT or NET with goserelin and tamoxifen. The primary purpose was to evaluate the non-inferiority of NET compared to NCT using clinical response, assessed by MRI. Besides, pathological complete response rate (pCR), changes in Ki-67 expression, breast conservation surgery (BCS) rate, and quality of life were included as secondary endpoints. Results A total of 187 patients were assigned to receive NCT (n = 95) or NET (n = 92), and 87 patients in each group completed treatments. More NCT patients had complete response or partial response than NET patients using MRI (NCT 83.7% vs. NET 52.9%, 95% CI 17.6–44.0, p < 0.001) and callipers (NCT 83.9% vs. NET 71.3%, 95% CI 0.4–24.9, p = 0.046). Three NCT patients (3.4%) and one NET patient (1.2%) showed pCR (p < 0.005). No difference existed in the conversion rate of BCS (13.8% for NCT vs. 11.5% for NET, p = 0.531) and Ki-67 change (p = 0.114) between the two groups. Nineteen NCT patients had treatment-related grade 3 or worse events compared with none in the NET group. Conclusions Better clinical responses were observed in pre-menopausal patients after 24 weeks of NCT compared to those observed after NET. Trial registration Clinicaltrials.gov, NCT01622361.

The aim of this study was to determine the prevalence of elevated serum HER2 ECD levels, the association between these levels and tissue HER2 overexpression, and the potential clinical prognostic value of HER2 ECD in primary invasive breast cancer. Methods Serum HER2 ECD levels were examined preoperatively in 2,862 consecutive stage I–III primary breast cancer patients between 2007 and 2009. Serum HER2 ECD levels were measured by chemiluminescence immunoassay (ADVIA Centaur), and the tissue HER2 status was assessed by immunohistochemistry and fluorescence in situ hybridization. The cutoff value for the serum level of HER2 ECD was set at 15.2 ng/ml. Results Among the 2,862 patients, 126 (4.4%) had elevated serum HER2 ECD levels, and HER2 was overexpressed in the tumor tissue of 692 patients (24.2%), with a concordance of 78.7%. Multivariate analysis revealed that elevated serum HER2 ECD was a significant independent prognostic factor for worse distant-metastasis-free survival [DMFS; hazard ratio (HR) = 2.50, 95% confidence interval (CI) = 1.5–4.3, P = 0.001] and breast-cancer-specific survival (BCSS; HR = 2.0, 95% CI = 1.1–3.8, P = 0.036), which were much stronger in patients with tissue HER2-positive tumors (DMFS: HR = 3.8, 95% CI = 2.0–7.0, P < 0.001; BCSS: HR = 2.6, 95% CI = 1.2-5.3, P = 0.012). Conclusions Given the prevalence of HER2 expression, its measurement as an independent prognostic factor can be clinically useful, particularly in patients with tissue HER2-positive tumors
