Stomach Carcinoma Presenting with a Synchronous Liver Cancer: A Case Report and Literature Review

Abstract

Multiple primary malignant neoplasms are two or more malignancies in an individual without any relationship between the tumors. Multiple primary malignancies are relatively rare but have increased in recent decades. Two cancers are commonly observed among those with multiple primary malignancies, but two malignancies of stomach and liver are relatively rare to be reported. Mechanisms of the tumors were unclear; we described a patient who had stomach carcinoma presenting with a synchronous liver cancer and investigated his family history; we suggest that family history may be a key risk factor and early detection for additional primary malignancies should be needed for patients who had specific cancer history in their pedigree. Early diagnosis may be the key risk factor affecting prognosis.

Three simultaneous primary urologic malignancies iA single patient: A case report and review of the literature

“…Several theories have been proposed to explain their occurrence but none have been proven. Certain risk factors seem to be the common denominator such as smoking and a family history of neoplasia [ 8 , 9 , 10 ] Concerning our patient, the family history is negative. He has no history of chemotherapy or radiation exposure.…”

A Case of Synchronous Primary Gastric Cancer and Primary Hepatocellular Carcinoma

“…Synchronous cancer is diagnosed simultaneously or within about 6 months, and metachronous cancers are secondary cancers that developed more than 6 months after the diagnosis and treatment of primary cancer. [3] The criteria of multiple primary tumors include. The etiology of multiple primary malignancies is unknown.…”

Simultaneous laparoscopic distal gastrectomy (uncut Roux-en-Y anastomosis), right hemi-colectomy and radical rectectomy (Dixon) in a synchronous triple primary stomach, colon and rectal cancers patient

“…The most common treatment is surgery associated with adjuvant treatment (6). In resectable multiple synchronous primary cancers, radical surgery with or without chemotherapy is the preferred treatment (7,8). In the present synchronous triple primary stomach, colon and rectal cancers patient, we have several questions.…”
