The histological classification of gastric adenocarcinoma influences its prognostic outcomes and therapeutic strategies. Although fibroblast growth factor (FGF)10 is important for gastric morphogenesis, its use as a molecular marker of gland-forming differentiation pattern remains undefined. The present study examined 117 surgically resected gastric adenocarcinoma specimens using immunohistochemical analysis to evaluate the expression of FGF10 and FGF receptor 2 (FGFR2).

Conversion surgery for gastric cancer is defined as surgery for tumors with distant metastases that are technically or oncologically unresectable at diagnosis, with the aim of achieving R0 resection after chemotherapy. However, there is no randomized controlled trial evidence comparing conversion surgery with continued chemotherapy at the stage of response to chemotherapy. In addition, there are no recommendations on appropriate targets, timing of surgery, extent of resection, pre-and post-operative chemotherapy regimens or duration of chemotherapy, which are issues that need to be resolved.

Studies have associated neutrophil-to-lymphocyte ratio (NLR) with overall survival (OS) and progression-free survival (PFS) in patients with gastric cancer (GC). The present study aimed to examine the relationship between dynamic changes in NLR during treatment and disease progression in patients with unresectable or recurrent GC treated with nivolumab monotherapy as a third-line or later regimen. Patients treated with nivolumab as a third-line or later therapy for unresectable or recurrent GC at Gifu University Hospital (Gifu, Japan) from April 2017 to December 2021 were included.

Article Synopsis
  • A study investigated the use of dual-energy computed tomography (DECT) to analyze lymph node metastasis in advanced esophageal cancer patients after chemotherapy and surgery.
  • Researchers extracted radiomics features and performed ROC analysis to assess the presence of pathological metastasis in 36 lymph nodes from 10 patients.
  • The study found that certain radiomics features, like long run emphasis and small zone emphasis, had significantly higher sensitivity for detecting metastasis compared to traditional measurements, suggesting DECT can enhance evaluations of lymph node involvement post-chemotherapy.

Article Synopsis
  • - The concept of oligometastasis in gastric cancer involves localized, technically resectable metastatic lesions that respond well to preoperative chemotherapy and have better survival odds with local treatments, sometimes paired with chemotherapy.
  • - Guidelines from the European Society for Medical Oncology and Japanese treatment guidelines recognize local treatment as a key option for oligometastasis, highlighting examples like solitary liver metastasis and localized lymph node metastasis.
  • - The AIO-FLOT3 trial showed positive results for multimodal treatments involving surgery and chemotherapy for oligometastasis, with ongoing studies further assessing the effectiveness of these approaches compared to palliative chemotherapy.

Introduction And Importance: Systemic sclerosis is a disease characterized by autoimmune inflammation, fibrosis of the skin and internal organs, and vasculopathy. Diverticula found in the intestines are a common feature in patients with systemic sclerosis, but esophageal epiphrenic diverticulum is extremely rare. We present a rare case of esophageal epiphrenic diverticulum treated with laparoscopic diverticulectomy and Heller myotomy in a patient with systemic sclerosis.

Background: Postoperative pancreatic fistula (POPF) is one of the serious complications of pancreatic surgery. When POPF occurs and becomes severe, it causes secondary complications and a longer treatment period. We previously reported a correlation between pancreatic fibrosis and magnetic resonance imaging (MRI) findings, and MRI may have the potential to predict POPF.

Pseudocirrhosis is a rare but important complication of metastatic cancer. We herein present the case of a patient with pseudocirrhosis occurring after a complete response to chemotherapy for metastatic gastric cancer was achieved. A 72-year-old man was diagnosed with gastric adenocarcinoma with multiple liver metastases.
