[Case managers experience improved trajectories for cancer patients after implementation of the case manager function]. / Koordinatorerne oplever bedre forløb for kræftpatienter efter indførelsen af forløbskoordinationsfunktionen.

Case managers are increasingly used to optimize trajectories for patients. This study is based on a questionnaire among case managers in cancer care, aiming at the clarification of the func­tion and its impact on especially patient safety, when handing over the responsibility. The results show a major variation in how the function is organized, the level of competence and the task to be handled. The responsibility has in general been nar­rowed to department level. Overall, the case managers believe that the function has optimized pathways for cancer patients and improved safety, but barriers persist.

[Recruiting medical students for the surgical education]. / Rekruttering til hoveduddannelsen i kirurgi i Danmark.

For a longer period the interest for surgical education in Denmark has been low measured in the number of junior doctors choosing a surgical career. The Danish Surgical Society has reviewed the published data describing the factors involved when selecting a surgical career.

Survival in patients with synchronous liver metastases in central and northern Denmark, 1998 to 2009.

OBJECTIVE: In Denmark, the strategy for treatment of cancer with metastases to the liver has changed dramatically during the period 1998 to 2009, when multidisciplinary care and a number of new treatments were introduced. We therefore examined the changes in survival in Danish patients with colorectal carcinoma (CRC) or other solid tumors (non-CRC) who had liver metastases at time of diagnosis. STUDY DESIGN AND METHODS: We included patients diagnosed with liver metastases synchronous with a primary cancer (ie, a solid cancer diagnosed at the same date or within 60 days after liver metastasis diagnosis) during the period 1998 to 2009 identified through the Danish National Registry of Patients. We followed those who survived for more than 60 days in a survival analysis (n = 1021). Survival and mortality rate ratio (MRR) at 1, 3, and 5 years stratified by year of diagnosis were estimated using Cox proportional hazards regression analysis. RESULTS: In the total study population of 1021 patients, 541 patients had a primary CRC and 480 patients non-CRC. Overall, the 5-year survival improved from 3% (95% confidence interval [CI]: 1%-6%) in 1998-2000 to 10% (95% CI: 6%-14%) in 2007 to 2009 (predicted value). The 5-year survival for CRC-patients improved from 1% (95% CI: 0%-5%) to 11% (95% CI: 6%-18%) whereas survival for non-CRC patients only increased from 5% (95% CI: 1%-10%) to 8% (95% CI: 4%-14%). CONCLUSION: We observed improved survival in patients with liver metastases in a time period characterized by introduction of a structured multidisciplinary care and improved treatment options. The survival gain was most prominent for CRC-patients.

Survival of patients with colon and rectal cancer in central and northern Denmark, 1998-2009.

OBJECTIVE: The prognosis for colon and rectal cancer has improved in Denmark over the past decades but is still poor compared with that in our neighboring countries. We conducted this population-based study to monitor recent trends in colon and rectal cancer survival in the central and northern regions of Denmark. MATERIAL AND METHODS: Using the Danish National Registry of Patients, we identified 9412 patients with an incident diagnosis of colon cancer and 5685 patients diagnosed with rectal cancer between 1998 and 2009. We determined survival, and used Cox proportional hazard regression analysis to compare mortality over time, adjusting for age and gender. Among surgically treated patients, we computed 30-day mortality and corresponding mortality rate ratios (MRRs). RESULTS: The annual numbers of colon and rectal cancer increased from 1998 through 2009. For colon cancer, 1-year survival improved from 65% to 70%, and 5-year survival improved from 37% to 43%. For rectal cancer, 1-year survival improved from 73% to 78%, and 5-year survival improved from 39% to 47%. Men aged 80+ showed most pronounced improvements. The 1- and 5-year adjusted MRRs decreased: for colon cancer 0.83 (95% confidence interval CI: 0.76-0.92) and 0.84 (95% CI: 0.78-0.90) respectively; for rectal cancer 0.79 (95% CI: 0.68-0.91) and 0.81 (95% CI: 0.73-0.89) respectively. The 30-day postoperative mortality after resection also declined over the study period. Compared with 1998-2000 the 30-day MRRs in 2007-2009 were 0.68 (95% CI: 0.53-0.87) for colon cancer and 0.59 (95% CI: 0.37-0.96) for rectal cancer. CONCLUSION: The survival after colon and rectal cancer has improved in central and northern Denmark during the 1998-2009 period, as well as the 30-day postoperative mortality.

[Future perspectives in liver surgery]. / Fremtidsperspektiver inden for leverkirurgi.

Resection of colorectal liver metastases will increase due to increased life expectancy and widened indications. Complex combinations of chemotherapy, surgery, and local ablation are used in advanced disease. Advances in laparoscopic and telerobotic liver resection are expected. Hepatocellular carcinoma is rare, results are poor, and better treatment is needed. The complex management of liver neoplasms requires a centralized effort. Further advances in xenotransplantation, artificial liver, and stem cell technology may influence liver transplantation as well as cancer surgery.

Polyposis and early cancer in a patient with low penetrant mutations in MSH6 and APC: hereditary colorectal cancer as a polygenic trait.

Hereditary non-polyposis colorectal cancer and familial adenomatus polyposis are autosomal dominant diseases accounting for 5-7% of all colorectal cancer cases. Inheritance of mutations associated with both syndromes in the same individual has, so far, only been observed in a few cases. This report outlines the findings in a proband of a HNPCC family, who presented with colorectal cancer and with multiple adenomas at the age of 18. He was shown to be compound heterozygous for MSH6 mutations: a nonsense mutation in exon 4 (c.1836 C>A, p.S612X); and a missense mutation in exon 5 (c.3226 C>T, p.R1076C). In addition, an APC missense mutation was revealed (c.7504 G>A, p.G2502S). Immunohisto-chemical analysis showed lack of expression of MSH6 in tumour tissue, as well as accumulation of betacatenin in the nuclei of the tumour cells. We suggest that the presence of mutations in both alleles of one gene and mutations in different genes, may influence the phenotype in hereditary colorectal cancer. Biallelic and/or polygenic mutations should be suspected when facing unusual severe variants of "classic monogenic phenotypes", such as HNPCC.

Long-term anorectal dysfunction after postoperative radiotherapy for rectal cancer.

PURPOSE: Adjuvant radiotherapy in the treatment of rectal cancer has been shown to increase long-term morbidity causing severe anorectal dysfunction with physiologic changes whose interaction remains poorly understood. This study examines long-term anorectal morbidity from adjuvant postoperative radiotherapy. METHODS: In a prospective study, patients with Dukes B or C rectal carcinoma were randomized to postoperative radiotherapy or no adjuvant treatment after anterior resection. The long-term effect of radiotherapy on anorectal function in a subset of surviving patients was assessed from a questionnaire on subjective symptoms and from physiology laboratory evaluation and flexible sigmoidoscopy. RESULTS: Twelve of 15 patients (80 percent) treated with radiotherapy had increased bowel frequency compared with 3 of the 13 patients (23 percent) who did not have radiation therapy (P = 0.003). The former group had loose or liquid stool more often (60 vs. 23 percent, P = 0.05), had fecal incontinence more often (60 vs. 8 percent, P = 0.004), and wore pad more often (47 vs. 0 percent, P = 0.004). They also experienced fecal urgency and were unable to differentiate stool from gas more often. Endoscopy revealed a pale and atrophied mucosa and telangiectasias in the irradiated patients. Anorectal physiology showed a reduced rectal capacity (146 vs. 215 ml, P = 0.03) and maximum squeeze pressure (59 vs. 93 cm H2O, P = 0.003) in the radiotherapy group. Impedance planimetry demonstrated a reduced rectal distensibility in these patients (P < 0.0001). CONCLUSIONS: Adjuvant postoperative radiotherapy after anterior resection causes severe long-term anorectal dysfunction, which is mainly the result of a weakened, less sensitive anal sphincter and an undistensible rectum with reduced capacity.
