HER2DX ERBB2 score in advanced HER2-positive gastric cancer treated with trastuzumab and chemotherapy.

Background: Response to trastuzumab combined with chemotherapy (T-chemo) in human epidermal growth factor receptor 2 (HER2)-positive advanced gastric cancer (AGC) varies widely, highlighting the need for more precise biomarkers beyond conventional HER2 assessment with immunohistochemistry (IHC) and in situ hybridization (ISH). The HER2DX ERBB2 messenger RNA (mRNA) assay, a clinically validated genomic test initially developed for early-stage HER2-positive breast cancer, quantitatively measures ERBB2 expression and may improve patient selection for T-chemo in AGC.

Patients And Methods: In a retrospective cohort of 134 patients with AGC, including 58 who received T-chemo, we evaluated whether the HER2DX ERBB2 score defines more accurately HER2 status and correlates with treatment response and survival outcomes in HER2-positive AGC, compared with standard pathology-based methods.

Pathophysiology of referred pain in dentistry: a case report.

This article presents the clinical case of a 42-year-old woman with chronic pain in her left temporomandibular joint (TMJ) and limited mouth opening. The patient also reported anxiety and difficulty sleeping. Cone beam computed tomography revealed impacted maxillary third molars and hypertrophy of the nasal turbinates.

Total neoadjuvant therapy with or without aflibercept in rectal cancer: 3-year results of GEMCAD-1402.

Background: The results of the Grupo Español Multidisciplinar en Cáncer Digestivo (GEMCAD)-1402 phase II randomized trial suggested that adding aflibercept to modified fluorouracil, oxaliplatin, and leucovorin (mFOLFOX6) induction, followed by chemoradiation and surgery, could increase the pathological complete response (pCR) rate in patients with high-risk, locally advanced rectal cancer. Here we update results up to 3 years of follow-up and evaluate the predictive value of consensus molecular subtypes identified with immunohistochemistry (IHC).

Methods: Patients with magnetic resonance imaging-defined T3c-d and/or T4 and/or N2 rectal adenocarcinoma in the middle or distal third were randomly assigned to mFOLFOX6 induction, with aflibercept (mF+A; n = 115) or without aflibercept (mF; n = 65), followed by capecitabine plus radiotherapy and surgery.
