Surgical outcomes in surgical oncology patients who participated in a family involvement program.

BACKGROUND: There is a lack of evidence regarding the relationship between family involvement and outcomes in gastrointestinal oncology patients after surgery. To evaluate the effect of a family involvement program for patients undergoing oncologic gastrointestinal surgery on unplanned readmissions within 30 days after surgery. METHODS: A multicenter patient-preference cohort study compared 2 groups: patients who participated in the family involvement program versus usual care. The program comprised involvement of family caregivers in care and training of health care professionals in family-centered care. Multivariable regression analyses were used to evaluate the effect of the FIP on the number of unplanned readmissions up to 30 days after surgery. Secondary outcomes included complications sensitive to fundamental care activities, emergency department visits, intensive care unit admissions, hospital length of stay, and the need for professional home care after discharge. RESULTS: Of the 301 patients included, 152 chose the family involvement program, and 149 chose usual care. Postoperative readmissions occurred in 25 (16.4%) patients in the family involvement program group, and 15 (10.1%) in the usual care group (P = .11). A significant reduction of 16.2% was observed in the need for professional home care after discharge in the family involvement program group (P < .01). No significant differences were found between the 2 groups in the other secondary outcomes. CONCLUSION: The family involvement program did not reduce the number of unplanned readmissions, but it led to a substantial reduction in-home care, which suggests an economic benefit from a societal perspective. Implementation of the family involvement program should, therefore, be considered in clinical practice.

Variations in stromal signatures in breast and colorectal cancer metastases.

The tumour microenvironment (TME) plays an important role in tumour survival and growth, but little is known about the degree of preservation between different stromal response patterns found in primary tumours and their metastases. We have previously identified gene expression profiles for two distinct stromal signatures in breast carcinoma of fibroblast (aka DTF) and macrophage (aka CSF1) response and found them to be correlated with clinicopathological features, including outcome. In this study, we compare the DTF fibroblast and CSF1 macrophage stromal response patterns in primary breast and colorectal cancers to their matched lymph node metastases. In both breast and colorectal cancer, there was a significant positive correlation between the CSF1 macrophage signature in the primary tumours and the matched lymph node metastases, as assessed by immunohistochemical markers. No such correlation was observed for the DTF fibroblast signature. A similar result was seen in independent analysis of two published gene expression microarray datasets. The variations of these stromal reaction patterns from the primary to the metastasis shed light on the relationship between the neoplastic cells and the non-neoplastic cells in the TME. The preservation of the CSF1 macrophage response pattern in metastases lends support to targeting the CSF1 pathway in cancer.

Patients' perception of colonoscopy: patients with inflammatory bowel disease and irritable bowel syndrome experience the largest burden.

BACKGROUND: Colonoscopy is a frequently performed procedure worldwide with a negative perception, leading to reluctance to undergo the procedure. Perceptions could differ depending on the specific indication for the colonoscopy. AIMS: To compare patient satisfaction with the colonoscopy procedure between five different patient groups: inflammatory bowel disease (IBD), familial predisposition for cancer, adenoma/carcinoma surveillance, symptoms suggestive of cancer, and irritable bowel syndrome (IBS). METHODS: A prospective questionnaire study was carried out in two regional hospitals and two tertiary teaching hospitals in the Netherlands. A total of 797 consecutive patients scheduled for colonoscopy between October 2009 and June 2010, 146 (18%) IBD, 153 (19%) adenoma or carcinoma surveillance, 104 (13%) familial predisposition, 280 (35%) symptoms suggestive of cancer, and 114 (14%) IBS-like symptoms, were included. Two questionnaires were administered: one on the day of the procedure and another 6 weeks after the procedure. The main outcome measurements were embarrassment, pain, burden, most burdensome aspect, and overall level of satisfaction. RESULTS: Patients with IBD and IBS reported significantly more embarrassment and burden from the bowel preparation phase (P=0.040 and 0.018, respectively) and more pain during the colonoscopy procedure (P=0.018). This difference in pain was also observed when adjusting for volume of sedation administered, familiarity with the endoscopist, duration of the colonoscopy, or whether or not an intervention was performed. All patient groups were less satisfied with the procedure at 6 weeks than directly after the colonoscopy; they recalled more embarrassment and burden, but less pain. CONCLUSION: Patient groups, defined by indication for colonoscopy, experience the colonoscopy procedure differently.

Multidetector CT scan for acute pulmonary embolism: embolic burden and clinical outcome.

BACKGROUND: In patients with acute pulmonary embolism (PE), the correlation between the embolic burden assessed by multidetector CT (MDCT) scan and clinical outcomes remains unclear. Patients with symptomatic acute PE diagnosed based on MDCT angiography were included in a multicenter study aimed at assessing the prognostic role of the embolic burden evaluated with MDCT scan. METHODS: Embolic burden was assessed as (1) localization of the emboli as central (saddle or at least one main pulmonary artery), lobar, or distal (segmental or subsegmental arteries) and (2) the obstruction index by the scoring system of Qanadli. The primary outcome was 30-day all-cause death or clinical deterioration. Predictors of all-cause death or clinical deterioration were identified by Cox regression statistics. RESULTS: Overall, 579 patients were included in the study; 60 (10.4%) died or had clinical deterioration at 30 days. Central localization of emboli was not associated with all-cause death or clinical deterioration (hazard ratio [HR], 2.42; 95% CI, 0.77-7.59; P 5 .13). However, in 516 hemodynamically stable patients, central localization of emboli (HR, 8.3; 95% CI, 1.0-67; P 5 .047) was an independent predictor of all-cause death or clinical deterioration, whereas distal emboli were inversely associated with these outcome events (HR, 0.12; 95% CI, 0.015-0.97; P 5 .047). No correlation was found between obstruction index (evaluated in 448 patients) and all-cause death or clinical deterioration in the overall study population and in the hemodynamically stable patients. CONCLUSIONS: In hemodynamically stable patients with acute PE, central emboli are associated with an increased risk for all-cause death or clinical deterioration. This risk is low in patients with segmental or subsegmental PE.
