Article Abstract
Purpose: Basophils play a crucial role in immunoglobulin E-mediated allergic reactions and parasitic infections. Recently, a low basophil count was reported to be a poor prognostic indicator in patients with malignant tumors. This study aimed to investigate the cut-off value to evaluate the clinicopathological and prognostic significance of the basophil count in patients with gastric cancer.
Methods: This study enrolled 1192 gastric cancer patient who underwent surgery without preoperative chemotherapy between 2001 and 2020. The cutoff value was 26/μl based on the receiver of characteristics curves for overall survival, and 606 patients were classified as the low basophil group. The clinicopathological and prognostic significance of the low basophil count was assessed by univariate and multivariate analyses.
Results: Elderly age (p < 0.001), high C-reactive protein level (p < 0.001), low lymphocyte count (p = 0.044), and low neutrophil count (p < 0.001) are independently associated with low basophil count. The low basophil group demonstrated a significantly worse overall survival than the high basophil group (p = 0.005). Although there was no significant difference in stage I, the low basophil group demonstrated poor overall survival in stage II/III/IV. In stage II, low basophil count was independently associated with poor OS. In stage III/IV, low basophil group tended to have poor overall survival rate. Including all stages, low basophil count was an independent risk factor for poor overall survival (hazard ratio (HR) = 1.29, 95% CI: 1.03-1.61, p = 0.027).
Conclusion: Low basophil count was significantly associated with elderly age, high C-reactive protein level, and low neutrophil count (<26/μl). In addition, low basophil count was an independent poor prognostic factor in patients with gastric cancer. Thus, preoperative circulating basophil count assessment may be useful for predicting the postoperative survival of patients with gastric cancer.

The role of inflammation in myopic retinopathy.

High myopia is a global health concern, often leading to degenerative retinal changes known as myopic retinopathy. Although mechanical stress, hypoperfusion, extracellular matrix remodeling, and growth factor dysregulation have been implicated in the pathogenesis of myopic retinopathy, emerging evidence highlights the critical role of chronic low-grade inflammation. Both innate and adaptive immune systems participate in myopic retinopathy through systemic and local inflammation.

C-C motif chemokine ligand 11 (CCL11), alternatively designated as eotaxin-1, is a low molecular weight chemokine that plays a crucial role in the mediation of allergic inflammation and immune regulation. This is achieved through the recruitment of eosinophils, T helper 2 (Th2) cells, and basophils via its primary receptor, CC chemokine receptor 3 (CCR3). Recent studies have identified elevated levels of CCL11 in the serum of cancer patients, suggesting its potential involvement in tumor biology.

Specific venom immunotherapy (VIT) in patients with hymenoptera venom allergy (HVA) represents a well-studied approach to reduce the severity of a possible anaphylactic reaction. Currently, data on mechanisms of tolerance induction at the cellular level within the first hours of therapy are lacking. To address this, total and unoccupied high-affinity IgE receptor (FcεRI) numbers per basophil, soluble FcεRI (sFcεRI) and serum tryptase levels were measured before and after the first day of VIT induction in HVA patients.

Microsecretory adenocarcinoma is a recently recognized low-grade salivary gland malignancy characterized by distinct histomorphological features, a specific immunophenotype, and recurrent gene fusion. This report describes 43-year-old woman with a two-decade history of a right buccal mucosa mass that exhibited recent enlargement, causing functional impairment. Surgical excision revealed a well-demarcated tumor with microcystic and tubular architecture, basophilic luminal secretions, and low proliferative activity (<1 mitotic figure/2mm).

Mast cells and basophils play important roles in allergic disorders associated with specific antigens and IgE. Crosslinking of the high-affinity IgE receptor (FcεRI) by specific antigens activates several tyrosine kinases, such as Lyn and spleen-associated tyrosine kinase (Syk), resulting in the release of calcium ions (Ca) from the endoplasmic reticulum (ER) into the cytoplasm. As Ca release from the ER is essential for the release of pro-inflammatory mediators, ER stress-related molecules, such as inositol-requiring enzyme 1α (IRE1α), may play roles in mast cell and basophil activation.
