BACKGROUND To investigate the clinical value of preoperative and postoperative radiotherapy (RT) in patients with rectal signet-ring cell carcinoma (SRCC). METHODS Using the Surveillance, Epidemiology, and End Results program patients with stage II-III rectal SRCC were retrospectively included between 1988 and 2012. Univariate and multivariate Cox regression analyses were performed to analyze...

OBJECTIVE To investigate the accuracy of preoperative computed tomography (CT), magnetic resonance (MR) imaging and diffusion-weighted imaging with background body signal suppression (DWIBS) in the prediction of nodal involvement in primary rectal carcinoma patients in the absence of tumor invasion into pelvic structures. METHODS AND MATERIALS Fifty-two subjects with primary rectal cancer wer...

Small cell carcinoma of the rectum is extremely rare. The present study aimed to improve the recognition of computed tomography (CT) and magnetic resonance imaging (MRI) features observed in patients with small cell carcinoma of the rectum. A total of 4 cases of patients with histologically confirmed small cell carcinoma of the rectum were retrospectively reviewed. The imaging features assessed...

BACKGROUND The most common pattern of recurrence of gastric cancer (GC) is peritoneal dissemination. However, rectal metastasis via hematogenous or lymphatic spread is exceedingly rare. We present a case of a 65-year-old man with an intramucosal GC who developed a rectal recurrence, possibly via a hematogenous route. CASE PRESENTATION A 65-year-old man underwent curative endoscopic submucosal...

AIM To investigate the incidence of colorectal cancer in the Split-Dalmatia County in the 1981-1998 period, and compare it with the incidence in the Republic of Croatia. METHODS The data were obtained using case records and registries of all hospitals and Public Health Institute in the County and the Croatian Cancer Registry. Age-standardized incidence per 100,000 was calculated from the numb...

Heterotopic bone is rarely present in malignant tumors of the gastrointestinal tract. We herein report a case of rectal adenocarcinoma with heterotopic bone. A 46-year-old Japanese male presented to our hospital with abdominal distension and constipation. Colonoscopic examination showed an ulcerated polypoid tumor of the rectum which nearly obstructed the rectal lumen. Abdominal computed tomogr...

Hand metastases occur infrequently, and metastatic tumors in the soft tissue of the hand caused by rectal cancer are extremely rare. We report a case here. The patient was a 76-year old man. He underwent Miles operation for rectal cancer located in the lower portion of the rectum. Histopathologically, the resected specimen showed well-differentiated adenocarcinoma. Six years postoperatively, a ...

Presacral abscess formation due to rectal stump insufficiency following Hartmann procedure is very rare complication. If the abscess cavity is large, it might delay the reversal of the stoma and will probably result in a devastating future functioning of the neorectum. Moreover, very invasive treatments will be required in order to prevent severe septic complications. We present the case of a 5...

OBJECTIVE To compare the efficacy of anal preserving surgery for aged people with low rectal carcinoma. METHODS Clinical data for a consecutive cohort of 98 rectal cancer patients with distal tumors located within 3 cm-7 cm of the anal verge were collected. Among these, 42 received anal preserving surgery (35 with Dixon, 3 with Parks and 4 with transanal operations). The local recurrence and ...
