A Solitary Duodenal Metastasis from Transverse Colon Cancer Detected Six Years after Curative Resection: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionRecurrence of colon cancer after 5 years or longer from primary surgery is relatively rare and furthermore, isolated metastasis to the duodenum is extremely rare. CASE PRESENTATION: The patient was a 79-year-old male. He underwent laparoscopic partial colectomy with radical lymphadenectomy for transverse colon cancer. Pathohistological examination revealed that the tumor stage was T4aN0M0, resulting in R0 resection. An oral adjuvant chemotherapy was administered only one course due to side effects. The serum carcinoembryonic antigen level began to increase after 5 years and 1 month postoperatively. An upper gastrointestinal endoscopy at 6 years postoperatively revealed a submucosal tumor at the inferior duodenal angle, and subsequent endoscopic ultrasound-fine needle aspiration confirmed the diagnosis of duodenal metastasis from transverse colon cancer. As no other metastatic lesion was detected, open partial duodenectomy was undergone and R0 resection was achieved. The patient has been under regular follow-up without adjuvant chemotherapy and has survived without recurrence for 2 years since the second surgery.
conclusionsAlthough extremely rare, the possibility of isolated duodenal recurrence after surgery for colon cancer exists. With a brief review of the literature, we report here a rare recurrence case of transverse colon cancer which was discovered at 6 years postoperatively and resulted in curative resection.
