Prognostic significance of osteosarcopenia in patients with stage IV gastric cancer undergoing conversion surgery.

Purpose: Recently, several investigators have focused on the clinical significance of osteosarcopenia in malignancies; however, its prognostic impact on patients with gastric cancer after conversion surgery (CS) remains unclear. Therefore, we aimed to investigate sarcopenia, osteopenia, and osteosarcopenia in this patient population.

Methods: We retrospectively analyzed 24 patients with gastric cancer who underwent CS.

Prognostic impact of preoperative osteosarcopenia on esophageal cancer surgery outcomes: a retrospective analysis.

Background: Osteosarcopenia, recognized as a consequence of aging, has garnered attention as a prognostic marker in recent years; however, its clinical significance in esophageal cancer remains uncertain. This study aimed to investigate the impact of osteosarcopenia on esophageal cancer surgery outcomes.

Methods: This retrospective study included patients with advanced esophageal cancer who underwent surgical resection between 2018 and 2021.

Clinical Significance of Body Weight Loss During Chemotherapy for Advanced Gastric Cancer Undergoing Conversion Surgery.

Background/aim: The purpose of the present study was to assess the clinical impact of body weight loss (BWL) during chemotherapy in patients with initially unresectable advanced gastric cancer who underwent conversion surgery.

Patients And Methods: This retrospective study included 61 patients with stage IV gastric cancer who underwent conversion surgery after chemotherapy, and body weight changes during chemotherapy were examined. Based on receiver operating characteristic (ROC) curve analysis of body weight change for disease recurrence, the cutoff value of BWL was determined.

LAT1 expression in colorectal cancer cells is unresponsive to HIF-1/2α accumulation under experimental hypoxia.

L-type amino acid transporter 1 (LAT1) is upregulated in various cancer types and contributes to disease progression. Previous studies have demonstrated or suggested that hypoxia-inducible factors (HIFs), the key transcription factors in hypoxic responses, control the expression of LAT1 gene in several types of cancer cells. However, this regulatory relationship has not been investigated yet in colorectal cancer (CRC), one of the cancer types in which the increased LAT1 expression holds prognostic significance.

Successful subtotal gastrectomy and hepatectomy for HER2-positive gastric cancer with liver metastasis after trastuzumab-based chemotherapy: a case report.

Background: Conversion surgery (CS) after chemotherapy is weakly recommended as a promising tool for improving prognoses in patients with unresectable gastric cancer. Moreover, several investigators have demonstrated the clinical efficacy of subtotal gastrectomy (sTG) with a small remnant stomach for the nutritional status and surgical outcome compared with total gastrectomy. Here, we report a patient with liver metastasis from human epidermal growth factor receptor 2 (HER2)-positive gastric cancer who underwent sTG and hepatectomy after trastuzumab-based chemotherapy.
