Prognostic Value of Tumor Regression Grade Combined with Pathological Lymph Node Status in Initially Node-Positive Rectal Cancer Treated with Neoadjuvant Chemoradiotherapy.

Department of Colorectal Surgery, Fudan University Shanghai Cancer Center, Shanghai, China.
Background: The prognostic value of tumor regression grade (TRG) after neoadjuvant chemoradiotherapy for rectal cancer is inconsistent in the literature. Both TRG and post-therapy lymph node (ypN) status could reflect the efficacy of neoadjuvant therapy. Here, we explored whether TRG combined with ypN status could be a prognostic factor for MRI-based lymph node-positive (cN+) rectal cancer following neoadjuvant chemoradiotherapy.

Neuromyelitis optica spectrum disorder (NMOSD) includes conditions with autoimmune genesis, which are manifested by attacks of optic neuritis (ON) and transverse myelitis (TM), and also express aquaporin 4 (NMO-IgG) or myelin oligo-endocytic glycoprotein (MOGAb) antibodies. In rare cases, the disease may also have a clinical presentation with only TM, without ON or with ON, without TM. These conditions are also included in the spectrum.

Accelerated partial breast irradiation (APBI) represents a valid option for adjuvant therapy of selected early breast cancer (BC). This single-institution prospective randomized study compares the health-related quality of life (HRQoL) between women treated with the highly conformal-external beam APBI technique and those with the more commonly used moderately hypofractionated whole breast irradiation (hypo-WBI). Eligible patients were women over 50 years with early BC (G1/2 DCIS ≤ 25 mm or G1/2 invasive non-lobular luminal-like HER2 negative carcinoma ≤ 20 mm) after breast-conserving surgery with negative margins.

J Neurooncol
January 2025
Department of Neurosurgery, University Hospital Leipzig, Leipzig University, Liebigstraße, 20, 04103, Leipzig, Germany.
Background: Pediatric meningiomas (PMs) are rare central nervous system tumors, accounting for 1-5% of all meningiomas, and differ from adult meningiomas in clinical, histopathological, and molecular features. Current guidelines primarily focus on adults, leaving a gap in evidence-based management for PMs. This study presents the largest meta-analysis of longitudinal individual patient data (IPD) to date, addressing progression-free survival (PFS) and overall survival (OS) in pediatric patients.

Non-small cell lung cancer (NSCLC) is the main histological subtype of lung cancer. For locally advanced and advanced NSCLC, epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI)-targeted therapy has been the first choice for NSCLC patients with EGFR mutations. TKIs, as targeted drugs, inhibit kinase activity and autophosphorylation by competitively binding to the ATP binding site of the EGFR tyrosine kinase domain, which blocks the signal transduction mediated by EGFR and thus inhibits the proliferation of tumor cells.
