Locally recurrent rectal cancer.
Summary of "Locally recurrent rectal cancer."
Over the last decades the therapy of rectal carcinoma has shown continuous improvement. Due to improvements in operative techniques, such as the establishment of total mesorectal excision (TME) and the combination of surgery and (neo-) adjuvant radiochemotherapy, the incidence of locally recurrent rectal cancer could be improved from nearly 50% to less then 10%. Nevertheless recurrent rectal carcinoma remains a severe problem. Predictive factors relating to locally recurrent rectal cancer are surgical experience, localization of the tumor, circumferential resection margins, stage-oriented multimodal therapy and a suitable oncological procedure for the primary tumor. In addition the tumor-specific biology also seems to be a relevant risk factor for recurrence. Operative treatment of locally recurrent rectal cancer was seen for a long time as a palliative procedure. Newer data show that resection of locally recurrent rectal cancer can be carried out with a curative intention in experienced institutions with a long-term 5 year survival of about 30% and mortality around 5%. The composite sacropelvic resection technique is a reasonable option in the curative treatment of locally recurrent rectal cancer. For the future the focus must be on improvements in the primary therapy of rectal carcinoma to avoid local recurrence. In addition early diagnosis of local recurrence and multimodal therapies will be of decisive importance.

Recurrent and locally advanced colorectal cancers frequently require en bloc resection of involved organs to achieve negative margins. The aim of this review is to evaluate the most current literature...
To compare the accuracy of different imaging modalities, alone and in combination in predicting findings at surgery after preoperative chemoradiation for locally advanced rectal cancer.
The first multidisciplinary consensus conference on colon and rectal cancer was held in December 2012, achieving a majority of consensus for diagnostic and treatment decisions using the Delphi Method....
Preoperative chemoradiotherapy (CRT) is the standard treatment modality in locally advanced rectal cancer. The primary aim was to correlate pathological complete response (pCR) with patient outcome, a...

Tumors or cancer of the RECTUM.
A cancer registry mandated under the National Cancer Act of 1971 to operate and maintain a population-based cancer reporting system, reporting periodically estimates of cancer incidence and mortality in the United States. The Surveillance, Epidemiology, and End Results (SEER) Program is a continuing project of the National Cancer Institute of the National Institutes of Health. Among its goals, in addition to assembling and reporting cancer statistics, are the monitoring of annual cancer incident trends and the promoting of studies designed to identify factors amenable to cancer control interventions.

A compound tubular gland, located around the eyes and nasal passages in marine animals and birds, the physiology of which figures in water-electrolyte balance. The Pekin duck serves as a common research animal in salt gland studies. A rectal gland or rectal salt gland in the dogfish shark is attached at the junction of the intestine and cloaca and aids the kidneys in removing excess salts from the blood.

Protrusion of the rectal mucous membrane through the anus. There are various degrees: incomplete with no displacement of the anal sphincter muscle; complete with displacement of the anal sphincter muscle; complete with no displacement of the anal sphincter muscle but with herniation of the bowel; and internal complete with rectosigmoid or upper rectum intussusception into the lower rectum.
Autosomal dominant neoplastic syndrome characterised by genodermatosis, lung cysts, spontaneous and recurrent PNEUMOTHORAX; and RENAL CANCER. It is associated with mutations in the folliculin protein gene (FLCN protein).
