Prostate Cancer Metastasis to the Stomach: 9 Years after the Initial Diagnosis—Case Report and a Literature Review

Abstract

Prostate cancer is one of the most common types of cancer in men [1]. It usually grows slowly and remains confined to the prostate gland, in which it need minimal or no treatment. However, metastatic prostate cancer many times results in poor outcome [2]. Common places of metastasis are to the bones and lymph nodes [3]. Visceral metastases are rare, but when they occur, they commonly involve the liver and lungs [3]. Moreover, involvement of the gastrointestinal (GI) tract is extremely rare. There are only a few cases of prostate cancer metastasis to the GI tract reported, including small bowel [4], esophagus [5, 6], and stomach [7–11]. The route of metastasis to the GI tract is unknown, although spread via the lymphatic channels has been postulated [12].We report a case of prostate cancer with metastasis to the stomach, 9 years after the initial diagnosis.
