B?cells are not required for T?cell priming in low zone tolerance to contact allergens and contact hypersensitivity
2004
Low zone tolerance (LZT) to contact allergens is induced by epicutaneous exposure to haptens in subsensitizing doses resulting in an inhibition of contact hypersensitivity (CHS), which, in contrast, occurs after sensitization with immunogenic doses of allergens. Performing the protocol of tolerance induction resulted in robust LZT to allergens in B cell-deficient mice in vivo, indicating that B cells are not required for the induction and effector phase of LZT. However, CHS reactions in vivo were restricted in B cell-deficient mice as compared to wild-type (WT) mice. In contrast, analysis of hapten-specific T cell activation in vitro revealed a strong proliferative response of T cells deriv…

Operable triple-negative breast cancers (TNBCs) have a higher risk of relapse than non-TNBCs with standard therapy.

Can We Define the Risk of Lymph Node Metastasis in Early-Stage Cervical Cancer Patients? A Large-Scale, Retrospective Study
2017
BACKGROUND: Sentinel lymph node (SLN) biopsy has emerged as one of the most appreciated techniques for reducing the rate of complete lymph node dissection (LND) performed in patients with early-stage cervical cancer (ECC). However, its performances are still a matter of debate and, to improve them, international guidelines recommend performing at least unilateral LND in case of SLN mapping. In a prior study, we identified a group of patients without evidence of lymph node metastasis (LNM). Our objective is to define a precise risk of LNM for each ECC patient in order to significantly tailor surgery for ECC. METHODS: Clinical and pathological data of ECC patients were retrospectively collect…
The role of sentinel lymph-node biopsy (SLNB) in the treatment of breast cancer.
2006
Sentinel lymph-node biopsy is an innovative method for axillary staging in breast cancer patients, based on the concept that information about the status of the entire lymphatic drainage from a tumour site could be obtained by identification and sampling of a "sentinel node". The aim of the study was to evaluate the impact of sentinel lymph-node biopsy in the management of patients with early invasive breast carcinoma. Three hundred and forty-one patients with primary invasive breast carcinoma measuring less than 2 cm (less than 3 cm from January 2001) and clinically negative axillary nodes were recruited into the study. Sentinel lymph-nodes were positive for metastases in 108/341 cases (31…
Is sentinel lymph node biopsy more accurate than axillary dissection on staging the nodal involvement in breast cancer patients?
2007
Today evaluation of axillary involvement can be routinely performed with the technique of sentinel lymph node biopsy (SLNB). One of the greatest advantages of SLNB is the nearly total absence of local postoperative complications. It is important to understand whether SLNB is better than axillary lymph-node dissection (ALND) for staging axillary nodal involvement. The aim of the study was to evaluate the axillary staging accuracy comparing three different methods: axillary dissection, sentinel node biopsy with the traditional 4-6 sections and sentinel node biopsy with complete analysis of the lymph node. 527 consecutive patients (525 females and 2 males) with invasive breast cancer < or = 3 …
Prophylactic Thyroidectomy in 75 Children and Adolescents with Hereditary Medullary Thyroid Carcinoma: German and Austrian Experience
1998
When mutations of the RETproto-oncogene were found in 1993 to account for hereditary medullary thyroid carcinoma (MTC), surgeons obtained the opportunity to operate on patients prophylactically (i. e., at a clinically asymptomatic stage). Whether this approach is justified, and, if so, when and to which extent surgery should be performed remained to be clarified. A questionnaire was sent to all surgical departments in Germany and Austria. All of the patients who fulfilled the following criteria were enrolled: (1) preoperatively proved RET mutation; (2) age/= 20 years, (3) clinically asymptomatic thyroid C cell disease; and (4) TNM classification pT0-1/pNX/pN0-1/M0. Seventy-five patients wer…
Validity of Laparoscopic Staging to Avoid Adjuvant Chemoradiation following Radical Surgery in Patients with Early Cervical Cancer
2012
<b><i>Purpose:</i></b> To determine the rate of unavoidable adjuvant chemoradiation (RCTX) due to histologic results after radical surgery in patients with early cervical cancer. <b><i>Patients and Methods:</i></b> Between May 2004 and July 2011, 448 consecutive patients diagnosed with invasive cervical cancer stage IA1 L1 to IIA underwent laparoscopic staging at the Department of Gynecology and Gynecologic Oncology at Charité Berlin. Only in patients without lymph node metastases (n = 394) on frozen section, radical operation was continued either by laparoscopic radical hysterectomy (n = 228) or by radical vaginal trachelectomy (n = 166). The…
Omitting axillary lymph node dissection after positive sentinel lymph node in the post-Z0011 era: Compliance with NCCN and ASCO clinical guidelines a…
2021
Summary Purpose In the ACOSOG Z0011 trial, patients with primary breast cancer and 1–2 tumor-involved sentinel lymph nodes (SLNs) undergoing breast-conserving surgery had no oncological outcome benefit after axillary lymph node dissection (ALND), despite a relevant rate of non-SLN metastases of 27%. According to the St Gallen expert consensus, and NCCN and ASCO clinical guidelines, ALND may be avoided in patients who meet all ACOSOG Z0011 inclusion criteria. This recommendation can also be extended to patients undergoing mastectomy, with 1 or 2 positive SLNs and an indication for chest wall radiation, in whom axillary radiotherapy can be proposed as an alternative to completion ALND. The ai…
Axillary Nodal Burden in Breast Cancer Patients With Pre-operative Fine Needle Aspiration-proven Positive Lymph Nodes Compared to Those With Positive…
2019
BACKGROUND/AIM: Recent years have seen a considerable shift to a more conservative management of the axilla in patients with positive axillary sentinel lymph nodes. The aim of this study was to determine whether some breast cancer patients with a preoperative ultrasound-guided needle aspiration biopsy proven positive node could potentially be spared an axillary lymph node dissection according to the ACOSOG Z0011 trial criteria. PATIENTS AND METHODS: A retrospective review was performed involving 623 breast cancer patients who underwent axillary lymph node dissection after either ultrasound-guided needle aspiration biopsy proven positive node or sentinel lymph node biopsy. RESULTS: Patients …
Immunohistochemical Investigation of Metastasis-Related Chemokines in Deep-Infiltrating Endometriosis and Compromised Pelvic Sentinel Lymph Nodes
2015
Endometriosis is a prevalent benign disease, despite sharing several similarities with malignancies, such as the possibility of lymphatic spread. In malignancies, chemokines play a sovereign role in the process of metastasis. Metastasis-related chemokine axes have not yet been assessed in deep-infiltrating endometriosis (DIE), and this investigation was the aim of our study. The expression of these chemokines was investigated by immunohistochemistry in rectovaginal DIE lesions and in matched pelvic sentinel lymph nodes (PSLNs) of patients with endometriosis (n = 27), and their expression in the eutopic endometrium (EE) of endometriosis-free women (n = 20) was used as controls. Their stainin…
