Preoperative low dose NSAID treatment influences the genes for stemness, growth, invasion and metastasis in colorectal cancer.

Preclinical data, and an increasing list of clinical investigations, show anti-inflammatory agents to favourably influence the biology of colorectal tumor. We have earlier reported on re-expression of activated immune cells after three days preoperative treatment of patients with colorectal carcinoma, randomized to receive oral NSAID (indomethacin or celebrex). Antisecretory prophylaxis (esomeprasol) was provided to all patients and served as sham treatment.

Genomic CGH-assessed structural DNA alterations in rectal carcinoma as related to local recurrence following primary operation for cure.

Several factors determine overall outcome and possible local recurrence after curative surgery for rectal carcinoma. Surgical performance is usually believed to be the most pertinent factor, followed by adjuvant oncological treatment and tumor histopathology. However, chromosomal instability is common in colorectal cancer and tumor clones are assumed to differ in aggressiveness and potential of causing local recurrence.

Downregulation of Prominin 1/CD133 expression in colorectal cancer by NSAIDs following short-term preoperative treatment.

Expression of Prominin 1/CD133 is associated with poor prognosis and chemoresistance in several types of solid tumors. The aim of the present study was, therefore, to evaluate Prominin 1/CD133 expression in colorectal carcinoma after short-term preoperative treatment by non-steroidal anti-inflammatory drugs (NSAIDs). Patients aimed at curative operation for colon cancer were randomized to receive NSAIDs (indomethacin 50 mg x2 or celecoxib 100 mg x2) three days preoperatively.

Local recurrence of rectal cancer: a population-based cohort study of diagnosis, treatment and outcome.

Aim: Local recurrence is an important endpoint of rectal cancer treatment, but details of this form of treatment failure are less well described. The aim of this study was to acquire deeper knowledge of local recurrence regarding symptoms, diagnostic work-up, clinical management, health-care utilization and outcome.

Method: Of 671 patients with rectal cancer, 57 were diagnosed with local recurrence within 5 years after surgery.

Sexual function after failed ileal pouch-anal anastomosis.

Background And Aims: Failure of ileal pouch-anal anastomosis (IPAA) occurs in around 10% of the patients. Compared to patients with functioning pouches, health related quality of life is deteriorated after failure. Sexual function in patients with pouch failure is however poorly studied.
