Lateral Pelvic Lymph Node Recurrence 5 Year after Endoscopic Mucosal Resection for Superficial Lower Rectal Cancer

چکیده
A 73-year-old woman underwent endoscopic mucosal resection for a 10-mm-diameter rectal polyp(Isp)within 5 cm of the anal verge in November 1995. Pathological examination showed that well-differentiated adenocarcinoma had invaded the submucosal layer with vascular invasion. Although secondary surgical treatment was recommended, the patient refused further treatment. Right-sided sciatica developed in December 2000,and metastasis to the right obturator lymph node was detected with computed tomography. Intrapelvic lymphadenectomy was performed in February 2001 and revealed no other metastatic lesions. Total mesorectal excision (TME)should be performed if another surgical procedure is to follow endoscopic mucosal resection. Because lateral pelvic lymph nodes are not dissected at TME, the procedure had no additional benefit for our patient. The secondary surgical treatment for early cancer in the lower rectum should selected carefully. (Jikeikai Med J 2006;53:163-6)

A 61-year-old woman underwent successful en bloc endoscopic submucosal dissection (ESD) for the management of a 4-cm, nodular, mixed-type, laterally spreading tumor located 11cm from the anal verge (●" Fig.1). Although the depth of submucosal invasion was 3000μm, the patient refused additional surgical treatment. Three weeks after ESD, the patient developed an extraperitoneal pelvic abscess, wh...

This report presents a case of para-aortic and lateral pelvic lymph node recurrence of rectal cancer that showed complete response to S-1 monotherapy. A 69-year-old man underwent low anterior resection for rectal cancer in 2007. Para-aortic lymph and right lateral pelvic lymph node recurrence occurred in 2008. He received a fluorouracil/folinic acid plus oxaliplatin regimen; however, G4 neutrop...
متن کاملA case of lateral pelvic lymph node recurrence after TME for submucosal rectal carcinoma successfully treated by lymph node dissection with en bloc resection of the internal iliac vessels.
In Japan, lateral lymph node dissection (LLND) is generally performed for the treatment of T3-4 lower rectal carcinoma, and not for T1 lower rectal carcinoma, because of a low positive rate in patients with T1 lesion. We experienced a rare case of lateral pelvic lymph node recurrence after total mesorectal resection for T1 lower rectal carcinoma, successfully treated by LLND with en bloc resect...
متن کاملClinical Outcomes of Gastrectomy after Incomplete EMR/ESD
PURPOSE Endoscopic resection is widely accepted as standard treatment for early gastric cancer (EGC) without lymph node metastasis. The procedure is minimally invasive, safe, and convenient. However, surgery is sometimes needed after endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD) due to perforation, bleeding, or incomplete resection [corrected]. We evaluated the role ...
متن کاملOptimal lymph node dissection for T3-T4 lower rectal cancer, the so-called "high risk" group: the Japanese experience.
The principal aim of radical surgery for rectal cancer is complete resection of the tumor together with its feeding and lymphatic vessels. There are two types of lymphatic flow from lower rectal cancer: proximal lymphatic flow, toward the root of the inferior mesenteric artery in the mesorectum, and lymphatic flow toward the pelvic sidewall alongside the internal iliac blood vessels beyond the ...
