Late onset pulmonary metastasis more than 10 years after primary sigmoid carcinoma.

Abstract

According to current guidelines, follow-up of patients with colorectal cancer is ended after five years. Also, chest X-ray is not part of standard investigation during follow-up. We describe a case of a 74-year-old patient, more than ten years after a sigmoid resection because of carcinoma of the sigmoid. No recurrence was detected during intensive follow-up. However, ten years after resection of the sigmoid adenocarcinoma, complaints of coughing induced further examination with as result the detection of a solitary metastasis in the left lung of the patient. Within half-a-year after metastasectomy of the lung metastasis, she presented herself with thoracic pain and dyspnea resulting in discovering diffuse metastasis on pulmonary, pleural, costal and muscular level. Five year follow-up of colorectal carcinoma without chest X-ray can be questioned to be efficient. The growing knowledge of tumor biology might in future adjust the duration and frequency of diagnostic follow-up to prevent (late) recurrence in patients with colorectal carcinoma.
