The clinicopathologic relevance and prognostic value of tumor deposits in colorectal cancer has been widely demonstrated. However, there are still debates in the prognostic value of tumor deposits and the applicability of N1c category in rectal cancer with preoperative radiotherapy. In this study, rectal cancer with preoperative radiotherapy followed by resection of primary tumors registered in...

BACKGROUND Stage IIIA rectal cancer has distinctive oncological features, including limited depth of intestinal wall invasion and early regional lymph node metastasis. We aim to compare survival outcomes and clinicopathological features for stage IIIA rectal cancer with those for stage II rectal cancer. METHODS We analyzed patients with stage II or stage IIIA rectal cancer treated with surger...

A Müllerian adenosarcoma is an extremely rare tumor characterized by a stromal component of usually low-grade malignancy and by a benign glandular epithelial component. A Müllerian adenosarcoma occurs mainly in the uterus, but also in extrauterine locations. Extrauterine Müllerian adenosarcomas are thought to arise from endometriotic deposits. A 36-year-old female presented to Daegu Catholic Un...

Transrectal ultrasound (TRUS)-guided biopsy of the prostate is a gold-standard for diagnosing the prostatic cancer. It is a relatively less invasive technique and known to be fast, safe, and effective method, because post biopsy complications including gross hematuria, rectal bleeding, hematospermia, fever and chill are mostly self-limiting and the rate of major complications are low. Rare majo...

Introduction: Radiation therapy is one of the main treatments for rectal cancer. In three-dimensional conformal radiotherapy, exposure of healthy tissue around the tumor is unavoidable. The small intestine is the most important organ at risk of rectal cancer radiotherapy. Intestinal complications are a major factor limiting the dose radiotherapy for rectal cancer. The most com...

Large (>2.5 cm) rectal laterally spreading tumors (LSTs) are often managed endoscopically with piecemeal endoscopic mucosal resection technique (pEMR). However, the mean recurrence rate after pEMR is 20% [1]. Furthermore, rectal LST-mixed granular type lesions (0-Is+IIa) demonstrate deep submucosal cancerous infiltration in 10.1% of cases [2]. Endoscopic submucosal dissection (ESD) is an endosc...

A 56-years-old man with a small rectal carcinoid tumor without carcinoid syndrome was admitted at Chareongkrung Pracharak Hospital with rectal bleeding. Proctoscopy revealed a small 7-mm rectal polyp, at 6 cm above the dentate line. Histology was diagnostic of a carcinoid tumor without atypical histopathologic feature or invasion into the muscularis propria . Immunohistochemical study was posit...

Rectal cancer metastatic to the breast is an exceedingly rare event with around 15 cases reported in the literature. A metastatic breast deposit from the rectum signifies diffuse disseminated disease or a highly aggressive tumor such that surgical intervention other than palliation has a limited role. In the present report, we discuss a patient who presented with rectal cancer and developed a b...

results twelve original studies fulfilled the inclusion criteria. the current literature suggests that the learning curve of robotic rectal surgery varies between 15 and 44 cases and is probably shorter to that of laparoscopic rectal surgery. conclusions there are only a few studies assessing the learning curve of robotic rectal surgery and they possess several differences in methodology and ou...
