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.

Hepatocellular carcinoma is one of the most common causes of death in Koreans. Most cases of hepatocellular carcinoma are beyond the stage of curative resection at the time of diagnosis due to extrahepatic metastasis as well as wide distribution of tumor in the liver. The lung is the most common site of extrahepatic metastasis but metastasis to gingiva is very rare in hepatocellular carcinoma. We report a case hepatecellular carcinoma with gingival methststasis in a 59 year old male patient.

Metastatic renal cell carcinoma is renowned for its potency to spread to almost any organ of the body; however metastasis to the gall bladder is very rare. We present a case of a 48 year old man who initially demonstrated renal cell carcinoma, and in who gallbladder metastasis was later detected. A review of the literature revealed only a small number of cases of renal cell carcinoma metastasizing to the gallbladder, and these were primary found upon necropsy. Gall-bladder metastasis in this case was detected clinically.

Since 2006, tyrosine kinase inhibitors and anti-angiogenic drugs have revolutionized the treatment of metastatic renal cell carcinoma by improving progression-free survival and overall survival. The prognostic factors in metastatic renal cell carcinoma treated by targeted therapy include anatomical, histological, clinical, biological, and molecular parameters. The accuracy of these prognostic factors are not high when applied alone. A renal cancer prognostic system that combines all these prognostic factors can improve the risk assessment of renal cancer and prognosis prediction, and thus guide clinical decision-making.
