Gastric cancer with liver metastasis (GCLM) is the leading cause of death in patients with advanced gastric cancer. Multiple metastasis was common in GCLM and usually complicated with lesions outside the liver, especially peritoneal metastasis. Most of liver metastasis lesions could not be resected radically. Currently, main treatments for GCLM included radical operation, palliative resection of gastric cancer, ablation of metastatic lesions, intervention and systemic chemotherapy. Based on the current progress in the treatment for GCLM and our clinical experience, the general status of patients, the type of gastric cancer and the degree of liver metastasis should be analyzed, and a cooperative multidisciplinary team (MDT) should be applied to conduct and to choose active and suitable comprehensive treatment for GCLM patients based on individualized therapy principle.

A 65-year-old male patient presented multiple cutaneous nodules on trunk and an erythematous inflammatory lesion resembling erysipelas on left side of neck. Result of skin biopsies disclosed groups of metastatic adenocarcinoma cells in the dermis, subcutaneous tissue, and lumina of the lymphatic vessels. Histopathologic examination of the stomach, along with the gastroscope, established that the cutaneous metastasis was of stomach origin.

Blood-borne metastatic involvement of the stomach by cancer is a rare entity. According to the number of reports in the literature, the most common tumors that spread to the stomach through the blood stream are malignant melanoma, breast carcinoma and lung carcinoma. Recently, two cases of metastatic involvement of the stomach secondary to lung carcinoma were diagnosed by gastroscopy. The first patient was a 66-year-old man who had primary lung carcinoma with multiple bone and subcutaneous metastases. Gastroscopy showed multiple submucosal tumors with central umbilications in the fundus and in the upper body of the stomach. Pathologic examination revealed massive submucosal infiltration and conical shaped and scanty deep mucosal infiltration of undifferentiated small cell carcinoma suggestive of metastatic involvement. The second patient was a 68-year-old man who had primary lung carcinoma with brain metastasis. Gastroscopy showed a large fungating mass in the greater curvature side of the stomach. Pathologic examination revealed poorly differentiated squamous cell carcinoma. We report the two cases of metastatic gastric cancer from lung carcinoma with the literature review.

Gastric metastasis of lung carcinoma is a rare entity which is detected mostly at autopsy. Patients diagnosed as having those on lifetime are extremely rare. In addition to our case, 54 cases of lung carcinoma metastasis to the gastro-intestinal tract have been reported in the literature since 1961. We report a case of gastric metastasis originated from small cell lung carcinoma. The patient was a 87-year-old man. He refused lung biopsy and further treatment and died 2 months after the diagnosis. This is the case of gastric metastsis originated from lung carcinoma, which was confirmed by immunohistochemical staining.

The most common metastatic sites of gastric cancer are liver, lung, bone and adrenal gland. However, skin metastases from gastric cancer are relatively rare. We herein report a case of advanced gastric cancer with perianal skin metastasis in a 70-year-old male. On admission, patient presented with epigastric pain. Endoscopy and abdominal CT scan demonstrated the stage IV gastric cancer. He had one painless nodule on perianal skin area, biopsy of that lesion showed a feature of poorly differentiated adenocarcinoma clinically from the stomach. We suspected that the perianal lesion was originated from gastric cancer.

Peritoneal metastasis of gastric cancer serving as the most frequent form of metastasis, is one of the leading causes of death. A portion of surgically treated patients often suffer from small peritoneal residual metastasis, which will lead to recurrence and metastasis of gastric cancer patients after surgery. Given these, the prevention and treatment of peritoneal metastasis of gastric cancer deserves more attention. Molecular residual disease (MRD) refers to the molecular abnormalities of tumor origin that cannot be found by traditional imaging or other laboratory methods after treatment, but can be found by liquid biopsy, representing the possibility of tumor persistence or clinical progress. In recent years, the detection of MRD based on ctDNA has gradually become a research hotspot in the prevention and treatment of peritoneal metastasis. Our team established a new method for MRD molecular diagnosis of gastric cancer, and reviewed the research achievements in this field.

Liver metastasis from gastric cancer is a major cause of cancer-related death. Since liver metastasis from gastric cancer is usually associated with other non-curative factors, such as peritoneal metastasis, lymph node metastasis and extensive intrahepatic metastasis, the hepatic resection rate was low and the prognosis was poor. The main risk factors of liver metastasis were serosal invasion, p(+), N3-N4, differentiated histologic type, medullary type of poorly differentiated adenocarcinoma, vascular invasion, and overexpression and mutation of VEGF, P53 and c-erbb-2. The 5-year survival rate after hepatic resection of synchronous and metachronous liver metastasis from gastric cancer ranged from 11% to 42%. Appropriate patient selection for hepatic resection may confer a better prognosis of liver metastasis from gastric cancer.
