Overall survival after resection for colon cancer in a national cohort study was adversely affected by TNM stage, lymph node ratio, gender, and old age

Background A national surveillance program of colon cancer treatment was introduced in 2007. We examined prognostic factors for colon cancer operated in 2000 with an aim of improving survival in the new program and a special focus on the merit of lymph node yield. Methods A cohort of 269 patients, 152 women (56.5%), with a mean age of 71 years, was operated for colon cancer in 2000 at three teaching hospitals and followed up for 7 years. Results Overall 5-year survival was 58.0%, and overall hospital mortality was 5.2%, with 4.5% in elective cases and 12.5% after urgent surgery. In only 41.1% of the specimens were 12 or more lymph nodes retrieved, but this did not affect survival in the combined cohort, although one of the hospitals achieved a significantly better result with a harvest of 12 or more lymph nodes. In a multivariate analysis, old age, gender, a high lymph node ratio (LNR) at stage III, and tumor–node–metastasis stage were adverse factors for survival. Conclusions The operative mortality was high and should be reassessed. The lymph node count did not have a significant impact on outcome overall, whereas the LNR proved significant for stage III. A prospective protocol using overall lymph node yield as a surrogate measure for more radical surgery, nevertheless, seems warranted to improve the lymph node harvest according to international recommendations

Erratum: Outcome after Introduction of Complete Mesocolic Excision for Colon Cancer Is Similar for Open and Laparoscopic Surgical Treatments

<b><i>Background:</i></b> Complete mesocolic excision (CME) and a high (apical) vascular tie may improve oncologic outcome after surgery for colon cancer. Our primary aim was to emulate a previous national result of 73.8% overall survival (OS) with both the open and laparoscopic techniques. <b><i>Methods:</i></b> A prospective study of radical colon cancer was initiated in a Norwegian community teaching hospital in 2007 and comprised a consecutive group of 251 patients with TNM stages I-III that had surgery according to the CME principle. Oncological outcome was assessed as OS, disease-free survival (DFS) and cancer-specific survival (CSS), as well as time to recurrence (TTR), using Cox regression analysis. <b><i>Results:</i></b> In-hospital mortality was 3.6%, 2.3% for laparoscopic surgery and 4.9% for open management. Significantly more patients in the open CME group developed complications in the short term (p < 0.001). Twelve or more lymph nodes were retrieved from 82.9% (208/251) of the specimens. Overall 3-year OS was 84.5%, DFS 77.4%, CSS 91.5% and TTR 86.8%. The surgical approach was not a significant predictor for any of the survival parameters. <b><i>Conclusions:</i></b> There was no survival difference between open and laparoscopic CME colonic resections, and the present OS improved from a previous OS from 2000

Healing by primary versus secondary intention after surgical treatment for pilonidal sinus

Background: Pilonidal sinus arises in the hair follicles in the buttock cleft at the bottom of the backbone. The estimated incidence is 26 per 100,000, people, affecting men twice as often as women. The mean age of presentation is 21 years (men) and 19 years (women) respectively. Pilonidal sinus results in chronic discharging wounds that cause pain and impact upon quality of life and social function. These sinuses may become infected and present as acute abscesses. Management of these abscesses is uncontroversial and revolves around incision and drainage, however, the mode of surgical management of the chronic discharging sinus is debatable. Surgical strategies traditionally centre on excision of the sinus tracts followed by primary closure and healing by primary intention or leaving the wound open to heal by secondary intention. There is uncertainty as to whether open or closed surgical management is more effective. Objectives: To determine the relative effects of open compared with closed surgical treatment for pilonidal sinus on the outcomes of time to healing, infection and recurrence rate. Search strategy: We sought relevant trials from the Wounds Group Specialised Register (Searched 13/6/07); The Cochrane Central Register of Controlled Trials (CENTRAL) (2007, Issue 2); Ovid MEDLINE (1950 - May Week 5 200&); Ovid EMBASE (1980 - 2007 Week 23); Ovid CINAHL (1982 - June Week 2 2007). We checked the bibliographies of review and primary articles for relevant studies and contacted authors of all included studies. Selection criteria: All randomised controlled trials (RCTs) evaluating open with closed surgical treatment for pilonidal sinus. Exclusion criteria were: non-RCTs; children aged younger than 14 years and studies of pilonidal abscess. Data collection and analysis: Screening of eligible studies, data extraction and methodological quality assessment of trials were conducted independently by two review authors. Data from eligible studies were recorded using data extraction forms and any disagreements were referred to a third review author. Results were presented using mean differences for continuous outcomes and relative risk with 95% confidence intervals for dichotomous outcomes. Main results: Eighteen studies were included (1573 patients). Twelve RCTs compared open healing with primary closure, 10 of which used midline closure and 2 trials used off-midline closure. Six studies compared midline and off-midline closure. Open compared with closed techniques: Evidence suggested more rapid healing after primary closure although there was no difference in the infection rate after wound closure. Recurrence was less likely to occur after open healing (RR 0.42; 95% CI 0.26 to 0.66) suggesting a 58% lower risk of recurrence after open wound healing compared with primary closure. Patients returned to work earlier after primary closure (WMD 10.48 days 95% CI 5.75 to 15.21 days). There was no difference between the two groups for other complications and length of stay. There were few useable data on cost, patient satisfaction and pain. Closed midline compared with closed off-midline: there was good evidence of slower healing, higher rates of infection (RR 4.70; 95% CI 1.93 to 11.45), higher rates of recurrence (Peto OR 4.95; 95% CI 2.18 to 11.24) and other complications (RR 8.94; 95% CI 2.10 to 38.02) after midline primary closure compared with off-midline closure techniques. Authors' conclusions: No clear benefit was shown for surgical management by primary closure or open healing by secondary intention. A clear benefit was shown for off-midline closure rather than midline closure after pilonidal sinus surgery. Off-midline closure should be the standard management when primary closure is the desired surgical option. Copyright © 2008 The Cochrane Collaboration. Published by John Wiley & Sons, Ltd

A strengths based method for homeless youth: effectiveness and fidelity of Houvast

Contains fulltext : 118569.pdf (publisher's version ) (Open Access)BACKGROUND: While homelessness among youth is a serious problem, there is little information about evidence-based interventions for homeless youth. In cooperation with professionals and youths, Wolf (2012) developed Houvast (Dutch for 'grip'): a strengths based method grounded in scientific and practice evidence. The main aim of Houvast is to improve the quality of life of homeless youths by focusing on their strengths, thus stimulating their capacity for autonomy and self-reliance. METHOD/DESIGN: The effectiveness and fidelity of Houvast will be tested in ten Dutch services for homeless youth which are randomly allocated to an intervention group (n = 5), or a control group which provides care as usual (n = 5). Measurements of both objective and subjective quality of life and secondary outcomes (mental and physical health, substance use, coping, resilience, psychological needs, care needs, working relationship with the professional and attainment of personal goals) will be conducted among homeless youths (n = 251). Youths in both groups will be interviewed by means of a structured interview at baseline, at time of ending care or after having received care for six months (T1) and at nine months after baseline (T2). Model fidelity will be tested around T1. DISCUSSION: This study is unique as it includes a large number of homeless youths who are followed for a period of nine months, and because it focuses on a strengths based approach. If the Houvast method proves to be effective in improving quality of life it will be the first evidence-based intervention for homeless youth.
