[A Large Gastric Gastrointestinal Stromal Tumor Successfully Treated with Neoadjuvant Imatinib Followed by Surgery-A Case Report].

Neoadjuvant imatinib may prevent tumor rupture and the need for extended surgery by reducing the tumor size by approximately 35%, especially for large gastric gastrointestinal stromal tumors(GISTs), as shown in a previous phase Ⅱ study (Kurokawa et al. BJC 2017); however, the use ofneoadjuvant imatinib is not prevalent in clinical practice. Herein, we report a large gastric GIST that was successfully treated with neoadjuvant imatinib.

The impact of pulmonary metastasectomy from gastric cancer.

Gastric cancer remains the most commonly-occurring cancer and the third most frequent cause of cancer-associated mortality in Japan. Solitary pulmonary metastasis of gastric cancer is rare and the outcome of pulmonary metastasectomy is still unclear. Herein we report the impact of pulmonary resection in patients with metastasis from gastric cancer.

Aggressive undifferentiated pleomorphic sarcoma of the stomach involving long-term survival: A case report and literature review.

Primary gastric undifferentiated pleomorphic sarcoma (UPS) is a rare disease with insufficient long-term follow-up data. In the present study, a 70-year-old male complained of abdominal fullness and visited our hospital. Abdominal computed tomography revealed a large tumor in the upper part of the stomach, which was accompanied by smaller tumors in the small intestinal mesentery.
