Preceding endoscopic submucosal dissection for T1 colorectal carcinoma does not affect the prognosis of patients who underwent additional surgery: a large multicenter propensity score-matched analysis

ConclusionsPreceding ESD with histological en bloc resection for patients with T1 CRC did not affect their oncologic behavior adversely after additional surgery.

Here, we describe a case of minor papillary adenocarcinoma in adenoma that was treated with endoscopic mucosal resection (EMR). In a 67-year-old woman, sigmoid colon cancer was incidentally detected on preoperative upper gastrointestinal endoscopy. Endoscopy revealed a slightly elevated lesion at the minor duodenal papilla. The findings of a histopathologic examination were suggestive of adenocarcinoma. Computed tomography and magnetic resonance images identified a minute tumor, whereas endoscopic ultrasonography revealed that the tumor did not spread to the pancreas. We performed EMR of this lesion. There were no complica...

A 67-year-old woman was admitted to our department for one-month duration of asthenia. She was previously operated of upper right lobectomy for a high-grade sarcomatoid carcinoma. The patient was hemodynamically stable. Hemoglobin was 5.4  g/dL, and she was transfused with three blood units. An upper gastrointestinal endoscopy was carried out and it was unremarkable; a colonoscopy was then performed and a voluminous ulcerated polyp with a large base of implantation of the proximal descending colon was seen and removed without compl ications (Fig.

We examined T1 CRC patients treated during 1992 –2008 and who had ≥5 years of follow-up. Patients who did not meet the curative criteria after ER according to the Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines were defined as “non-endoscopically curable” and classified into three groups: ER alone (Group A: 121 pat ients), additional surgery after ER (Group B: 238 patients), and surgical resection alone (Group C: 342 patients). Long-term outcomes and predictors of recurrence were analyzed.ResultsOf the 882 patients with T1 CRC, 701 were non-endoscopically curable. Among thes...

Conclusion The characteristics and pathophysiology of a primary signet-ring cell carcinoma of the colon and rectum are not well understood. Usually only palliative treatment is possible. The importance of an early diagnosis of this tumor is mandatory to have a curative approach.

We report the first case of early gastric cancer just above a heterotopic pancreas for which the differential diagnosis was carcinoma arising from heterotopic pancreas. Routine upper gastrointestinal endoscopy in an 83-year-old man with sigmoid colon cancer revealed a gastric cancer in the lesser curvature of the antrum. Endoscopic ultrasonography (EUS) for evaluating the depth of tumor invasion revealed a hypoechoic mass in the submucosal layer. The depth of tumor invasion was diagnosed as muscularis propria. Distal gastrectomy and sigmoidectomy were performed. Histologically, the resected specimen of the stomach unexpect...

Conclusions: Approximately 1 in 20 patients diagnosed with a primary breast cancer of lobular pathology will have metastatic spread to the GI tract, presenting approximately 4 years after their initial primary diagnosis. The most common presentation of metastatic disease is small bowel obstruction, with the most common site of spread being the stomach. There remains a paucity of data in the literature and our project is one of the first to further characterize these patients. Future research is needed in developing treatment regimens for these patients, as the 5-year survival is only approximately 1 in 4. Citation Format: ...
