Does the 'Liverpool Care Pathway' facilitate an improvement in quality of care for dying cancer patients?

BACKGROUND: The Liverpool Care Pathway for the Dying Patient (LCP) aims to transfer hospice principles of care for dying patients to other health-care sectors. This post-bereavement survey explored the LCP's effectiveness in improving quality of care for cancer patients. METHODS: Postal self-completion questionnaires were sent to 778 next-of-kin to consecutive deceased patients who had died an 'expected' cancer death in a hospice and acute tertiary hospital. RESULTS: Following exclusions (n=53), 255 of the 725 next-of-kin agreed to participate (35.2% response rate). Overall hospice participants reported the best quality of care, and hospital participants, for whom care was not supported by the LCP, reported the worst quality of care. Multivariate analysis showed the hospice was an independent predictor for patients being treated with dignity (OR 8.46) and receiving adequate family support (OR 7.18) (P<0.0001). Care supported by the LCP and the hospital specialist palliative care team were both associated with good family support, but neither was an independent predictor. CONCLUSIONS: From the bereaved relatives' perspective, within the hospital, the LCP is effective in improving specific aspects of care, such as symptom control for dying patients. Further improvement is required, however, to attain the hospice standard of care.

Survival differences between European and US patients with colorectal cancer: role of stage at diagnosis and surgery.

BACKGROUND: Population based colorectal cancer survival among patients diagnosed in 1985-89 was lower in Europe than in the USA (45% v 59% five year relative survival). AIMS: To explain this difference in survival using a new analytic approach for patients diagnosed between 1990 and 1991. SUBJECTS: A total of 2492 European and 11 191 US colorectal adenocarcinoma patients registered by 10 European and nine US cancer registries. METHODS: We obtained clinical information on disease stage, number of lymph nodes examined, and surgical treatment. We analysed three year relative survival, calculating relative excess risks of death (RERs, referent category US patients) adjusted for age, sex, site, surgery, stage, and number of nodes examined, using a new multivariable approach. RESULTS: We found that 85% of European patients and 92% of US patients underwent surgical resection. Three year relative survival was 69% for US patients and 57% for European patients. After adjustment for age, sex, and site, the RER was significantly high in all 10 European populations, ranging from 1.07 (95% confidence interval 0.86-1.32) (Modena, Italy) to 2.22 (1.79-2.76) (Thames, UK). After further adjustment for stage, surgical resection, and number of nodes examined (a determinant of stage), RERs ranged from 0.77 (0.62-0.96) to 1.59 (1.28-1.97). For some European registries the excess risk was small and not statistically significant. CONCLUSIONS: US-Europe survival differences in colorectal cancer are large but seem to be mostly attributable to differences in stage at diagnosis. There are wide variations in diagnostic and surgical practice between Europe and the USA.

Prognostic value of morphology and hormone receptor status in breast cancer - a population-based study.

We analysed the 5-year relative survival among 4473 breast cancer cases diagnosed in 1990-1992 from cancer registries in Estonia, France, Italy, Spain, the Netherlands and the UK. Among eight categories based on ICD-O codes (infiltrating ductal carcinoma, lobular plus mixed carcinoma, comedocarcinoma, 'special types', medullary carcinoma, not otherwise specified (NOS) carcinoma, other carcinoma and cancer without microscopic confirmation), the 5-year relative survival ranged from 66% (95% CI 61-71) for NOS carcinoma to 95% (95% CI 90-100) for special types (tubular, apocrine, cribriform, papillary, mucinous and signet ring cell); 27% (95% CI 18-36) for cases without microscopic confirmation. Differences in 5-year relative survival by tumor morphology and hormone receptor status were modelled using a multiple regression approach based on generalised linear models. Morphology and hormone receptor status were confirmed as significant survival predictors in this population-based study, even after adjusting for age and stage at diagnosis.

Socioeconomic variation in colon cancer tumour factors associated with poorer prognosis.

Analysis of population-based registry data (n=7393) showed that more deprived colon cancer patients had lower risk of the mucin-producing adenocarcinoma subtype, proximal subsite (to the descending colon), and no greater risk of high-grade tumours. Tumour factors therefore appear unlikely to account for socioeconomic gradients in survival.

Surgery for midgut carcinoid.

Many clinicians prefer to avoid surgery in patients with carcinoid neoplasia, because of its slow growth and relatively favourable prognosis. Nevertheless, the commonest cause of death in patients with carcinoid is advanced metastatic disease, and both clinical and epidemiological data indicate that the more effectively the disease is ablated, the more long-lasting the benefit. Multidisciplinary management of patients with carcinoid must consider inherited risk, possible multiple carcinoids and/or synchronous non-carcinoid cancer, and the use of a range of investigations that also evaluate the 10% of patients with carcinoid syndrome with or without valvular heart disease. Although primary size is correlated with the presence of nodal with or without liver metastases, carcinoid tumours <1 cm in diameter may be metastatic at presentation, particularly those arising within the small intestine. In the jejunum and ileum, resection of all sizes of carcinoid with local and regional nodes is preferred, to prevent nodal dissemination causing mesenteric ischaemia with or without infarction. Resection of nodal metastases should be undertaken in those with persistent or recurrent nodal disease if possible. Appendiceal and right colonic carcinoids are most effectively treated by right hemicolectomy with local and regional nodal clearance, as for adenocarcinoma. However, for most appendiceal carcinoids which are <1 cm in diameter and non-invasive, appendicectomy alone is sufficient. For appendiceal carcinoids 1-2 cm in diameter, histopathological assessment helps to determine the need for hemicolectomy. Liver resection has been followed by prolonged 5 year survival in several series and is recommended in appropriate patients to attempt cure or to debulk metastatic disease. Liver transplantation has had only qualified success in highly selected patients without extra-hepatic disease in whom other therapies have failed.

Histopathologic types of benign breast lesions and the risk of breast cancer: case-control study.

The hypothetical multistep model of carcinogenesis indicates that breast cancer develops via a series of intermediate hyperplastic lesions through in situ to invasive carcinoma. To identify the risk inherent within the different morphologic lesions, we have analyzed the data from 674 benign biopsy specimens comprising 120 cases who subsequently developed breast cancer and 382 controls (matched for age and date of biopsy) spanning a period up to 20 years of follow-up (mean 66.95 months). In this series we have confirmed an increased risk associated with certain types of benign breast lesions. Atypical lobular hyperplasia was the most significant risk factor for breast cancer with more unfavorable outcome in patients <50 years of age (p = 0.003) and a relative risk (RR) of 4.55 (confidence interval [CI] 1.77-11.69). Hyperplasia of usual type showed an RR of 1.53 (CL 1.10-2.13) with a statistically worse probability of survival (cancer-free time) for patients >50 years. For atypical ductal hyperplasia the RR was 2.03 (CI 0.80-1.39). Blunt duct adenosis was significantly more common in cases progressing to breast cancer compared with controls, showing an RR of 2.08 (CI 1.12-2.85). We describe in detail the criteria of morphologic changes observed in blunt duct adenosis and define, for the first time, the level of risk associated with each of its six subtypes. Improved knowledge of breast carcinogenesis will provide insight for defining high-risk groups thus resulting in improved screening and management regimens.
