BACKGROUND Current American Society of Clinical Oncology guidelines for management of sentinel node micrometastases (SNMM) in breast cancer recommend axillary lymph node dissection (ALND) for all patients. OBJECTIVE To assess nationwide use of ALND for SNMM. DESIGN Population-based retrospective observational study. SETTING The National Cancer Institute's Surveillance, Epidemiology, and E...
BACKGROUND The significance of micrometastatic disease in the sentinel lymph nodes (SLN) of patients with invasive breast cancer has been questioned. The objective of our study was to review the impact of micrometastatic carcinoma detected by SLN biopsy. STUDY DESIGN Between January 1997 and May 2004, 2,408 patients with invasive breast cancer and an SLN with micrometastatic (N0[i+], N1mi) or...
CONTEXT Sentinel lymph node dissection (SLND) accurately identifies nodal metastasis of early breast cancer, but it is not clear whether further nodal dissection affects survival. OBJECTIVE To determine the effects of complete axillary lymph node dissection (ALND) on survival of patients with sentinel lymph node (SLN) metastasis of breast cancer. DESIGN, SETTING, AND PATIENTS The American C...
Non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) represent a heterogeneous group of malignant lymphoid tumors, which have distinct histological and/or biological characteristics with preferential nodal involvement. However, none of the previous studies have assessed the prevalence of common NHL and HL subtypes at each nodal site of involvement. The aim of our study was to determine the prev...
We present one matrix multiplication algorithm for two{dimensional arrays of processing nodes, and one algorithm for three{dimensional nodal arrays. One{dimensional nodal arrays are treated as a degenerate case. The algorithms are designed to utilize fully the communications bandwidth in high degree networks in which the one{, two{, or three{dimensional arrays may be embedded. For binary n-cube...
BACKGROUND A few retrospective studies have indicated that neoadjuvant chemotherapy (NAC) in breast cancer may change biomarker profiles of the primary tumor. Little is known about the status of HER-2 gene of the synchronous nodal metastases when that of the residual tumor undergoes negative conversion in a neoadjuvant setting. CASE PRESENTATION We describe a female patient with left breast c...
In the era of effective systemic therapy, the decision on whether or not to recommend post-operative adjuvant radiotherapy for intermediate risk breast cancer remains a point of discussion in many multidisciplinary tumour board meetings. Variations in advice regarding post-mastectomy radiotherapy have been demonstrated within the context of guideline-based practice [1]. A recent survey of nodal...
BACKGROUND For patients with breast cancer and metastases in the sentinel nodes, axillary dissection has been standard treatment. However, for patients with limited sentinel-node involvement, axillary dissection might be overtreatment. We designed IBCSG trial 23-01 to determine whether no axillary dissection was non-inferior to axillary dissection in patients with one or more micrometastatic (≤...
Abstract Objectives We compared the clinicopathologic features, clinical management, and outcomes of human epidermal growth factor receptor 2 (HER2)–expressing nonexpressing microinvasive breast carcinomas (MiBC) to explore significance HER2 in MiBC. Methods Clinicopathologic follow-up information cases with final diagnosis MiBC known status between 2007 2019 were analyzed. Results Nineteen (41...
