"Gastric cancer was detected during follow-up endoscopic examinations or in an upper gastrointestinal series in seven patients. All of the cancers were diagnosed as adenocarcinoma histopathologically. Endoscopic mucosal resection was performed in two patients, partial resection of the residual stomach was performed in three patients. One patient was treated by endoscopic mucosal resection as palliative therapy, since he had severe pulmonary emphysema. Total resection of the gastric tube was attempted in 2 advanced cases but was unsuccessful because of direct invasion of other organ by the cancer. The 5 patients who underwent curative resection are alive with no subsequent recurrence."

Of all 29 GTCs, endoscopic submucosal dissection (ESD) was performed in 10 GTCs with a completely curative resection rate of 90%, which was significantly higher than that of 7 GTCs treated with endoscopic mucosal resection (EMR) (14.3%, P = 0.004). In these 17 GTCs, no cancer recurrence developed during a median follow-up period of 24 months, and the 3-year survival rate was 80.8%."

BACKGROUND/AIMS: With the improvement of the outcome after esophagectomy for esophageal cancer, patients with metachronous gastric cancer (MGC) in the reconstructed thoracic stomach have been observed in clinical practice. This study is a report of experiences with MGC with an emphasis on clinical pictures and treatment results. METHODOLOGY: Medical records were reviewed of 728 patients who underwent surgery for esophageal cancer at Samsung Medical Center between 1994 and 2004. MGC was defined as follows; (1) diagnosed more than 6 months after esophagectomy, (2) squamous cell carcinoma in histology of the surgically resected esophagus, (3) adenocarcinoma in histology of the stomach biopsy or surgical specimen. The clinicopathologic characteristics of MGC were evaluated. RESULTS: Eight patients (1.1%) of 728 patients were diagnosed with MGC. All patients were male and had a history of active smoking and drinking. The median age at the time of diagnosis of MGC was 67.8 years old (range: 62-76). Three patients (37.5%) were asymptomatic. Two patients (25%) complained of epigastric pain and 3 patients (37.5%) complained of obstructive symptoms including regurgitation, aspiration, dysphagia, and vomiting. The median interval between diagnosis of MGC and esophagectomy was 37 months (range: 8-85). Three MGCs (37.5%) were detected by endoscopic examination but not by computed tomography (CT). Three patients (37.5%) received surgery and were alive without recurrence for 12, 18 and 63 months respectively. One patient (12.5%) received radiation therapy and was alive for 69 months. Four patients (50%) received no treatment because of follow-up loss in 2 patients (25%) and death within days of MGC diagnosis in 2 patients (25%). CONCLUSIONS: Favorable outcomes can be obtained by active treatment in patients with MGC after esophagectomy. Regular endoscopic follow-up is important for early detection and more effective treatment of MGC, especially in areas where the incidence of gastric cancer is high.

[A difficult case]

13 years after Ivor Lewis operation and chemotherapy for upper esophageal cancer (squamous cell carcinoma, pT3N1), gastric tube cancer was found at 37 cm from the incisor teeths. Biopsy showed tubular adenocarcinoma, moderately differentiated with focal poorly differentiated component.

Based on the endoscopic findings (depressed lesion, converging folds) and histologic findings, I recommended surgery. However, the surgeon recommended performing ESD due to the high surgical risk. ESD was done.


ESD: Early gastric carcinoma
1. Location : Intrathoracic stomach, IT 37cm
2. Gross type : EGC type IIa+IIb
3. Histologic type : tubular adenocarcinoma, moderately differentiated, >> tubular adenocarcinoma, poorly differentiated (poorly cohesive)
4. Histologic type by Lauren : mixed
5. Size of carcinoma : (1) longest diameter,14 mm (2) vertical diameter, 18 mm
6. Depth of invasion : invades submucosa, (depth of sm invasion : 2000 §­) (pT1b)
7. Resection margin : involved deep resection margin by carcinoma, safety margin : distal 4 mm, proximal 1 mm, anterior 4 mm, posterior 2 mm, deep 0 §­
8. Lymphatic invasion : present (+++)
9. Venous invasion : not identified(N)
10. Perineural invasion : not identified(N)
11. Microscopic ulcer : absent
12. Histologic heterogeneity: present

Based on the pathology, surgery is necessary. The problem is the surgical risk. Surgical consultation was done. I explained the situation to the patient in detail.
