Aim: To determine the influence of excision repair cross complementing group 1 (ERCC1) codon 118 polymorphism and mRNA level on the clinical outcome of gastric cancer patients treated with oxaliplatin-based adjuvant chemotherapy.
Methods: Eighty-nine gastric cancer patients treated with oxalipatin-based adjuvant chemotherapy were included in this study. ERCC1 codon 118 C/T polymorphism was tested by polymerase chain reaction-ligation detection reaction (PCR-LDR) method in peripheral blood lymphocytes of those patients; and the intratumoral ERCC1 mRNA expression was measured using reverse transcription PCR in 62 patients whose tumor tissue specimens were available.
Results: No significant relationship was found between ERCC1 codon 118 polymorphism and ERCC1 mRNA level. The median relapse-free and overall survival period was 20.1 mo and 28.4 mo, respectively. The relapse-free and overall survivals in patients with low levels of ERCC1 mRNA were significantly longer than those in patients with high levels (P<0.05), while there was no significant association found between ERCC1 118 genotypes and the disease prognosis. Multivariate analysis also showed that ERCC1 mRNA level was a potential predictor for relapse and survival in gastric cancer patients treated with oxaliplatin-based adjuvant chemotherapy (P<0.05).
Conclusion: ERCC1 codon 118 polymorphism has no significant impact on ERCC1 mRNA expression, and the intratumoral ERCC1 mRNA level but not codon 118 polymorphism may be a useful predictive parameter for the relapse and survival of gastric cancer patients receiving oxaliplatin-based adjuvant chemotherapy.

Objective: Proximal gastrectomy (PG) is commonly used to remove proximal gastric cancer leading to gastroesophageal reflux and requires digestive tract reconstruction. This study is to compare the performance of esophagogastrostomy (EG), jejunal interposition (JI), and double tract reconstruction (DTR) on post-PG reconstruction effectiveness.
Methods: A retrospective study was conducted using the clinical data of 94 PG patients who underwent digestive tract reconstruction by EG (37 patients), JI (29 patients) or DTR (28 patients).

Gastric cancer is a malignant gastrointestinal disease characterized by high morbidity and mortality rates worldwide. The occurrence and progression of gastric cancer are influenced by various factors, including the abnormal alternative splicing of key genes. Recently, RBM39 has emerged as a tumor biomarker that regulates alternative splicing in several types of cancer.

Purpose Of Review: Human epidermal growth factor receptor 2 (HER2) is a critical target in advanced gastric cancer (AGC). This review highlights the current treatment landscape, lessons learned from past clinical trials, and prospects for future treatment strategies for HER2-positive AGC.
Recent Findings: Trastuzumab had been the standard treatment for HER2-positive AGC for a decade, and subsequently, trastuzumab deruxtecan, an antibody-drug conjugate (ADC), emerged with an impressive response.

Purpose Of The Review: This narrative review aims to provide an overview of recently completed randomized trials and expert consensus recommendations, and their implications for clinical practice and future trial design in patients with de-novo esophagogastric oligometastatic disease (OMD).
Recent Findings: The IKF-575/RENAISSANCE phase III trial showed no significant overall survival difference between systemic therapy alone and systemic therapy combined with local therapy for patients with gastric or gastroesophageal junction cancer and de-novo OMD, except for patients with retroperitoneal lymph node metastases only. The ESO-Shanghai 13 phase II trial demonstrated superiority of adding local therapy to systemic therapy for progression-free and overall survival in oligometastatic esophageal squamous cell carcinoma.
