Abstract
INTRODUCTION: Although no consensus has been reached on the role of surgical treatment for metastatic gastric cancer, some reports suggest promising results on patients with a small disease volume upon presentation. We present two cases of metastatic disease with a favorable outcome following surgical treatment.
PRESENTATION OF CASES: The first case presented with an adenocarcinoma of the cardia, which was staged as oligometastatic due to a small liver nodule on segment III. Treatment consisted of neoadjuvant chemotherapy followed by laparoscopic esophagectomy and hepatectomy. The patient remains disease-free 62 months after surgery. Unlike the first case, the second case presented with a large number of liver nodules upon diagnosis, ruling out metastasectomy as a possible treatment. The tumor expressed HER2 receptors and responded favorably to chemotherapy plus trastuzumab for 34 months. At this point, disease progression was observed on the primary site, but the hepatic lesions remained stable. The patient underwent gastrectomy, resumed the chemotherapy regimen, and had a favorable outcome, with stability of the liver metastasis and no local recurrence following primary tumor resection.
DISCUSSION: We illustrate through these two cases the effectiveness of a combined approach featuring perioperative chemotherapy and radical surgery for selected cases of oligometastatic gastric cancer, which we hope will spur further research on the topic.
CONCLUSION: Systemic treatment in metastatic gastric cancer may represent a novel treatment approach that allows surgical resection of the primary tumor in select cases.
