Solitary cardiac metastasis of rectal adenocarcinoma

Abstract

Solitary cardiac metastasis is rarely recognized. We report a case of solitary cardiac metastasis from a rectal adenocarcinoma that was manifested as superior vena cava (SVC) syndrome. Invasion of the deep cardiac structures was so severe that only its palliative resection and right atrial reconstruction were performed using a cardiopulmonary bypass to release the SVC obstruction. The postoperative course was uneventful and the patient was discharged home without any complications. Adjuvant chemotherapy could not be performed because of the renal dysfunction. Eleven months later, the patient died from multiple metastasis of adenocarcinoma. Even though the surgery was not curative, it might be effective for release from symptoms and for elongating life expectancy.

Cardiac metastasis from colorectal cancer: A case report

“…Although metastases of these unusual sites from colorectal cancer might occur with the status of widespread disease, cardiac metastasis from colorectal cancer is extremely rare [5][6][7][8][9][10][11][12][13] . The incidence of cardiac metastasis in patients with malignancy might be underestimated because cardiac metastatic lesions are clinically silent in most cases [13,14] .…”

“…Koizumi et al [11] reported that although surgery is rarely recommended for treating metastatic cardiac tumors, surgical treatment could be especially effective in occurrences of obstructive and solitary lesions to ensure relief from symptoms and elongation of life expectancy. In our case, the purpose of surgical treatment was the release of symptoms, even though the preoperative diagnosis was cardiac myxoma and the patient died from postoperative bleeding.…”

“…Although metastases to these sites might occur as a feature of end stagedisease, metastasis to the heart from colorectal cancer is extremely rare. To our knowledge, only nine cases of cardiac metastasis from colorectal cancer have been previously described [5][6][7][8][9][10][11][12][13] . Here, we report a case of cardiac metastasis from colorectal cancer that presented preoperatively as a benign atrial myxoma.…”

Cardiac Metastasis from Ascending Colon Cancer: A Case Report and Review of the Literature

“…To the best of our knowledge, there are only 14 reported cases of cardiac metastasis from colorectal cancer [9][10][11][12][13][14][15][16][17][18][19][20][21] . These 14 cases plus our case are shown in Table 2.…”
