RESUMO

AIM: To assess variability in the proportions of types of major resection for rectal cancer throughout the west of Scotland (WoS) and ascertain factors explaining the variability. METHOD: Retrospective cohort study of a regional population clinical audit database. This was linked to cancer registrations and death certificates in order that outcome analyses could be derived. Univariate and multivariate binary logistic regression analyses were used to explore determinants of survival. RESULTS: A total of 1574 patients met the inclusion criteria. The age range was from 22 to 97 years. The mean age was 67, median age 68 and the standard deviation was 11.5. The majority of patients (61%) were male. Unlike previous series, male patients and those with poorer socioeconomic circumstances (SEC) were no more likely to receive an abdominoperineal excision (APE) procedure for rectal cancer. CONCLUSION: Variation exists in the west of Scotland regarding surgical treatment for rectal cancer. We found no difference in the type of procedure offered according to sex, intent of operation or socioeconomic circumstances with reference to APE and anterior resection (AR) for rectal cancer. We conclude therefore that our region provides an equitable service on grounds of sex and SEC. This demonstrates that an equitable surgical service has been provided for those suffering from rectal cancer. Circumferential margin positivity was four times more likely in an APE than an AR for rectal cancer. This is not explained by age, stage, sex, socioeconomic circumstances (SEC), volume of surgery, intent of operation, type of admission or year of incidence.

RESUMO

BACKGROUND: Meta-analyses have indicated that preoperative mechanical bowel preparation (MBP) confers no clear benefit and may indeed be harmful for patients with colorectal cancer. The effects of bowel preparation on longer-term outcomes have not been reported. The aim was to compare long-term survival and surgical complications in patients who did or did not receive MBP before surgery for colonic cancer. METHODS: This was a retrospective cohort study of all patients undergoing potentially curative surgery for colonic cancer after routine hospital admission in the West of Scotland between January 2000 and December 2005. Clinical audit data were linked to cancer registrations and death certificates. Kaplan-Meier and Cox proportional hazards models were used to explore determinants of survival. RESULTS: A total of 1730 patients underwent potentially curative surgery for colonic cancer, of whom 886 (51·2 per cent) were men. The mean(s.d.) age was 69·7(10·6) years. Some 1460 patients (84·4 per cent) received MBP. Median follow-up was 3·5 (range 0·1-6·7) years. There were no statistically significant differences in 30-day postoperative complication rates between groups. The unadjusted hazard ratio (HR) for death from all causes for patients treated with MBP (versus no MBP) was 0·72 (95 per cent confidence interval 0·57 to 0·91). Multivariable analysis with adjustment for age, sex, socioeconomic circumstances, disease stage and presentation for surgery showed that MBP had no independent effect on all-cause mortality (HR 0·85, 0·67 to 1·10). CONCLUSION: Neither postoperative complications nor long-term survival are improved by MBP before colonic cancer surgery.

RESUMO

BACKGROUND: Terminal haemorrhage is a rare but devastating event that may occur in certain advanced cancers. The focus of management involves administration of 'crisis medicine' with the intention of relieving patient distress through sedative doses of anxiolytics or opioids. This practice, whilst widely accepted, is based on limited evidence and has never been formally evaluated. AIM: To evaluate the utility of crisis medication in the management of terminal haemorrhage, through the experiences of nurses who had personally managed such events. METHOD: Semi-structured interviews exploring the experiences of palliative care and head and neck oncology nurses were recorded, transcribed verbatim and analysed using interpretative phenomenological analysis. Saturation of themes occurred after interviewing 11 nurses with cumulative experience of managing 37 terminal haemorrhages. RESULTS: Participants reported crisis medication to have little, if any, role in the management of terminal haemorrhage, which was such a rapid event that patients died before it could be administered. As many events had not been predicted, anticipatory prescribing of crisis medication did not always occur. Staying with and supporting the patient, and using dark-coloured towels to camouflage blood were reported to be of more practical use. A focus on accessing crisis medicines had often been to the detriment of these simple yet beneficial measures. CONCLUSION: Anticipatory prescribing of crisis medication rarely benefits the patient and may unintentionally detract from nursing care. Guidelines on the management of terminal haemorrhage should reconsider the emphasis on crisis medication and focus on non-pharmacological approaches to this invariably fatal event.

RESUMO

Battin et al examined data on deaths from physician-assisted suicide (PAS) in Oregon and on PAS and voluntary euthanasia (VE) in The Netherlands. This paper reviews the methodology used in their examination and questions the conclusions drawn from it-namely, that there is for the most part 'no evidence of heightened risk' to vulnerable people from the legalisation of PAS or VE. This critique focuses on the evidence about PAS in Oregon. It suggests that vulnerability to PAS cannot be categorised simply by reference to race, gender or other socioeconomic status and that the impetus to seek PAS derives from factors, including emotional state, reactions to loss, personality type and situation and possibly to PAS contagion, all factors that apply across the social spectrum. It also argues, on the basis of official reports from the Oregon Health Department on the working of the Oregon Death with Dignity Act since 2008, that, contrary to the conclusions drawn by Battin et al, the highest resort to PAS in Oregon is among the elderly and, on the basis of research published since Battin et al reported, that there is reason to believe that some terminally ill patients in Oregon are taking their own lives with lethal drugs supplied by doctors despite having had depression at the time when they were assessed and cleared for PAS.

RESUMO

Access to adequate clinical information is essential for out-of-hours palliative care teams and general practitioners, specific examples to illustrate and justify this need are surprisingly rare in the medical literature. Without access to the full clinical background the patient in this lesson may have been inappropriately admitted to a palliative care unit and delayed investigations would have misguided the admitting doctor's assessment, planned investigations and management.

RESUMO

OBJECTIVE: Ileal pouch-anal anastomosis (IPAA) is the operation of choice for patients with ulcerative colitis. Free radical activity and the status of lipid soluble antioxidant vitamins have not been previously assessed in patients with IPAA. The aim of the present study was to measure the plasma concentrations of lipophyllic antioxidants and free radical activity in IPAA patients and compare them with normal subjects. METHOD: Forty-eight IPAA patients and 50 healthy controls were studied. A dietary assessment of vitamin E (alpha-tocopherol) and carotene was undertaken and plasma antioxidant status was assessed. Plasma malondialdehyde (MDA) was measured to assess the extent of free radical damage. In IPAA patients, association between the degree of inflammation in the pouch mucosa and the plasma concentration of lipophyllic antioxidants and extent of free radical activity was investigated. RESULTS: The dietary intake of carotene was similar in both groups. Intake of vitamin E was significantly lower in patients than controls (P = 0.01). In the IPAA group plasma concentrations of alpha-carotene, beta-carotene and lycopene were significantly lower (P < 0.001) and alpha-tocopherol:cholesterol ratio significantly higher (P < 0.001). Free radical damage was significantly greater in patients than controls (P < 0.01). There were no significant correlations between the degree of inflammation in the pouch and plasma concentrations of MDA, carotenoids, alpha-tocopherol:cholesterol ratio or intake of vitamins. CONCLUSION: Compared with normal subjects, patients with IPAA have significantly lower plasma concentrations of lipophyllic antioxidants alpha-carotene, beta-carotene and lycopene and higher free radical activity suggesting increased oxidative stress. These differences do not appear to be related to diet and do not correlate with histological severity of pouch inflammation.

RESUMO

BACKGROUND: GPs with a special interest and with specific training in palliative medicine (GP advisors) supported professional carers (mostly GPs) through a telephone advisory service. Each telephone call was formally documented on paper and subsequently evaluated. OBJECTIVE: Data from 2003 were analysed independently to reveal how often and in what way palliative sedation and euthanasia were discussed. METHODS: The telephone documentation forms and corresponding evaluation forms of two GP advisors were systematically analysed for problems relating to the role of sedation and/or euthanasia both quantitatively and qualitatively. RESULTS: In 87 (21%) of 415 analysed consultations, sedation and/or euthanasia were discussed either as the presenting question (sedation 26 times, euthanasia 37 times and both 10 times) or arising during discussion (sedation 11 times and euthanasia three times). Qualitative analysis revealed that GPs telephoned to explore therapeutic options and/or wanted specific information. Pressure on the GP (either internal or external) to relieve suffering (including shortening life by euthanasia) had often precipitated the call. On evaluation, 100% of the GPs reported that the advice received was of value in the patient's care. CONCLUSION: GPs caring for patients dying at home encountered complex clinical dilemmas in end-of-life care (including palliative sedation therapy and euthanasia). They valued practical advice from, and open discussion with, GP advisors. The advice often helped the GP find solutions to the patient's problems that did not require deliberately foreshortening life.

RESUMO

Despite level 1 evidence supporting the use of low-molecular weight heparin thromboprophylaxis in hospitalised cancer patients, only 7% of specialist palliative care units (SCPU) have thromboprophylaxis guidelines. The reasons for this are unclear. To explore specialist palliative care units (SPCU) directors' views on thromboprophylaxis in the inpatient unit, audiotaped semi-structured interviews were conducted with SCPU medical directors to explore factors influencing thromboprophylaxis practice. Purposive sampling of units known not to have thromboprophylaxis guidelines was conducted (as identified from previous research). The hospice directory was used to sample from units in each region of Great Britain and Ireland to ensure representation across the specialty. Interviews were transcribed and analysed using interpretative phenomenological analysis (IPA). Four major and four sub themes were identified. Participants were progressive in their attitudes to palliative care and comfortable with instigating active interventions for patient benefit. Symptomatic venous thromboembolism (VTE) was rarely seen and therefore not considered important enough to warrant guidelines. There was concern that evidence informing thromboprophylaxis guidelines in the general population was not transferable to the advanced cancer population and that the outcome measures from these studies were less meaningful to a palliative care patient. Thromboprophylaxis was considered a life prolonging intervention which may result in a poorer death than one because of VTE. Nevertheless, participants were receptive to change if presented with convincing evidence derived from a representative population. Until the true prevalence and symptomatic burden of VTE is known, the role of thromboprophylaxis in the SPCU setting will remain controversial. There is a need for a well-designed study to explore the utility of thromboprophylaxis in the palliative care inpatient setting. However, this will require meaningful outcome measures to be used within a clinically applicable population.

RESUMO

Magnetic resonance (MR) imaging may contribute to staging rectal cancer and inform the decision regarding administration of pre-operative radiotherapy. The accuracy of MR has been debated. The aim of the present study was to determine the accuracy of thin section T2-weighted MR images in rectal cancer patients. MR results were compared with histological assessment of resection specimens. Over a 2-year period, 42 patients were studied. Histological staging was pT2 n = 13, pT3 n = 25 and pT4 n = 4. MR diagnostic accuracy was 74%. MR sensitivity and specificity was 62% and 79% for pT2 lesions, 84% and 59% for pT3 lesions and 50% and 76% for pT4 lesions. Estimation of tumour penetration by thin section MR imaging of rectal cancers using pelvic phased-array coil has moderate diagnostic accuracy. The limitations of MR should be acknowledged when selecting rectal cancer patients for pre-operative radiotherapy.

RESUMO

Health-related quality of life (HRQoL) assessment is important in healthcare outcomes. This study aimed to determine the feasibility, reliability and validity of the Malay McGill Quality of Life Questionnaire--Cardiff Short Form (MMQOL-CSF) in advanced cancer population. Patients either completed the MMQOL-CSF alone or in addition to its long version. The study recruited 116 participants (average age = 44 years old). On average, MMQOL-CSF was completed in 5.4 minutes. Most domains showed evidence of reliability (Cronbach's alpha = 0.76-0.92). Correlation with its long version was moderate to strong (r(s) = 0.54-0.87). The MMQOL-CSF was a feasible, reliable and valid HRQoL instrument in this population.

RESUMO

PURPOSE: We have previously shown that 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] inhibits the proliferation of a number of human cancers, including colorectal and hepatocellular carcinoma, both of which affect the liver and are major causes of cancer death. However, the clinical use of 1,25(OH)2D3 and analogues has been restricted by the development of hypercalcaemia upon systemic administration. We hypothesized that a clinically significant hepatic first-pass effect may exist upon the administration of 1,25(OH)2D3 as a hepatic arterial infusion, and that such an effect may allow high levels of 1,25(OH)2D3 to be delivered to the liver whilst avoiding high systemic levels. METHODS: To examine this hypothesis, two groups of Landrace pigs were given identical doses of 1,25(OH)2D3 as continuous infusions, one group systemically, the other as a hepatic arterial infusion. Serum levels of 1,25(OH)2D3, calcium, phosphate and a number of liver and kidney function tests were performed regularly. RESULTS: Concentrations of 1,25(OH)2D3 and calcium remained normal in the hepatic arterial infusion animals, in contrast to the intravenous infusion animals which developed elevated levels of 1,25(OH)2D3 and hypercalcaemia. Hepatic arterial infusion of 1,25(OH)2D3 did not produce any adverse effects upon renal or hepatic function. CONCLUSION: The present findings support the existence of a clinically significant hepatic first-pass effect when 1,25(OH)2D3 is administered as a continuous hepatic arterial infusion. Hepatic arterial infusion of 1,25(OH)2D3 has great potential in the treatment of hepatic cancers.

RESUMO

The unpleasant smell of infected fungating tumors and benign cutaneous ulcers is a distressing clinical problem, known to be associated with anaerobic infection. Topical metronidazole 0.8% gel has been shown to decrease smell from fungating malodorous tumors. This study was conducted to assess prospectively the subjective and bacteriological response to 0.75% metronidazole gel to decrease smell from these lesions and to assess whether bacterial contamination of the tubes of gel occurs during use. Forty-seven patients with benign or malignant cutaneous lesions associated with a foul smell were assessed for smell, pain, appearance, and bacteriological profile before entry and at 7 and 14 days. Forty-one (95%) of the 43 patients assessed at 14 days reported decreased smell. Anaerobic infection was initially found in 25 (53%) of patients and was eliminated in 21 (84%) of these. At review after 7 days, patients reported less pain from the lesions. Discharge and associated cellulitis were also observed to decrease significantly.

RESUMO

A systematic review into palliative care team effectiveness was undertaken which has, inherent in its methodology, grey literature searching. Over 100 letters were written to a systematically chosen range of service providers, commissioners, and experts in combination with requests for information in six UK national cancer/palliative care organization newsletters. In addition, the System for Information on Grey Literature (SIGLE ) database was searched. As a result, 25 document hard copies were received. The documents were, in all but one case (this one study was also highlighted by the SIGLE search), not relevant as they were predominated by annual reports, service descriptions, and needs assessments. In terms of obtaining unpublished studies for possible inclusion in the review, this comprehensive search was unsuccessful and, therefore, it would appear that grey literature searching is not a useful tool in palliative care systematic reviews.

RESUMO

BACKGROUND: Hepatic resection is well established as a potentially curative treatment for hepatic colorectal cancer metastases. However, only a small proportion of patients with liver metastases are suitable for resection because they either have extrahepatic disease, or the extent and/or the distribution of their hepatic disease would make excision impossible. We have previously described the use of cryotherapy for inadequate resection margins and lesions in the remaining lobe of the liver. Combining such cryodestructive techniques with resection offers the possibility of increasing the proportion of patients to whom potentially curative treatment can be offered. The aim of this study was to compare survival in patients treated with resection and cryotherapy against those of patients treated with resection alone. Potential prognostic variables were also examined. METHOD: Patients undergoing a hepatic resection with or without cryotherapy at our unit between April 1990 and July 1997 were identified from our database and their notes reviewed. Survival was estimated using the Kaplan-Meier method and compared using the Log rank test. RESULTS: One hundred and seven patients were treated in total: 32 underwent resection alone, and 75 underwent resection combined with cryotherapy. There was no significant difference between the survival of patients treated with resection alone and those treated with resection and cryotherapy. CONCLUSIONS: Edge and contralobe cryotherapy can be combined with hepatic resection to allow a greater proportion of patients with hepatic colorectal metastases to be offered treatment, and results in similar survival figures comparable to hepatic resection for at least 3 years.

RESUMO

The steroid hormone 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3] has potential to be used as an anti-tumor agent, but its clinical application has been restricted by the strong systemic calcemic activity. Regional administration of the drug dissolved in lipiodol, might be a way of selectively delivering high concentrations of the drug to lipiodol avid tumor cells without causing systemic side effects. In acute (1 day treatment) and chronic (5 days treatment) experiments, efficacy of the drug dissolved in ethanol (control) or lipiodol and subsequently diluted in the culture medium was tested in vitro against the hepatoblastoma cell line HepG2. Using [3H]thymidine incorporation and cell count, antiproliferative effects of 1,25-(OH)2D3 dissolved in the two different solvents was compared. Microscopic examination of cells exposed to the lipiodol containing media revealed intra-cellular presence of the oil in abundance. Chronic treatment of cells with either formulation of 1,25-(OH)2D3 resulted in profound inhibition of cell proliferation. However, exposure of cells to 1,25-(OH)2D3 in lipiodol was followed by significantly greater and lasting inhibition of cell proliferation in both acute and chronic studies. These results indicate that, 1,25-(OH)2D3 dissolved in lipiodol probably acts as a sustained release drug depot formulation, in which case it could have some potential for the regional treatment of liver tumors.

RESUMO

It is well established that 1, 25 dihydroxyvitamin D3 is capable of inhibiting the proliferation of a number of human cancer cell lines, including hepatoma cell lines. However, clinical usage in the treatment of cancers has been limited by its hypercalaemic effects. We hypothesised that by delivering 1, 25 dihydroxyvitamin D3 dissolved in a lipid based carrier agent as a hepatic arterial infusion it would be possible to achieve high local concentrations within hepatomas for prolonged periods, whilst avoiding high systemic concentrations and hypercalcaemia. We examined this hypothesis by administering a hepatic arterial infusion of 1, 25 dihydroxyvitamin D3 in either Lipiodol, Medium Chain Triglyceride (MCT), or saline to hepatoma bearing rats. Assay of serum and tissue concentrations revealed that this approach using lipiodol or triglyceride results in selective distribution of 1, 25-dihydroxyvitamin D3 into, and retention within hepatoma tissue and low initial systemic serum levels. Lipiodol was more effective in these respects than MCT. This method of administration has potential in the treatment of hepatoma.

RESUMO

OBJECTIVES: The outcome of colovesical fistula management may be unsatisfactory; complications are reported in up to 45% of patients. Published studies are retrospective and tend to lack standardized management strategies and long-term follow-up. This cohort study assesses a policy of resection of colovesical fistulae in continuity with any distal colorectal stricture, and includes 5-year follow-up. METHOD: All patients undergoing surgery in our institution for colovesical fistula between February 1991 and April 1995 were entered into the study. The fistulae were resected in continuity with any distal bowel stricture, according to a standard single-stage operative protocol. Postoperative mortality and morbidity were recorded, and prospective review was undertaken at April 2000. RESULTS: Nineteen consecutive patients entered the study. The source of the fistula was diverticular disease (n = 14), colorectal cancer (n = 3), trauma (n = 1) or Crohn's (n = 1) disease. Thirteen patients had a colorectal stricture. One patient died due to ischaemic colitis within 30 days of surgery. Eleven other patients died of unrelated causes before April 2000, in whom there was no evidence of fistula recurrence before death at a median of 37 months after operation (range 2-95 months). At 5-year follow-up there was no evidence of fistula recurrence in the seven remaining patients. CONCLUSIONS: A policy of resection of the fistula and associated colorectal stricture with primary bowel anastomosis and bladder drainage, resulted in no recurrences and low morbidity. However comorbidity is important in this patient population, most of whom will die from unrelated causes within a few years.

RESUMO

The study aimed to pilot a grief awareness programme as a health promotion project for young offenders with complicated grief. Seventeen young offenders in custody at HM Prison, Cardiff were opportunistically recruited, interviewed about their bereavement, and offered entry to the programme. Young offenders who reported coping poorly with bereavement were more likely to have used drugs to cope with their emotions, to have had suicidal thoughts, and reported more depression and anxiety. They were also more likely to have been bereaved in late adolescence and to have lost a first degree relative, with death being sudden, violent or by suicide.

RESUMO

A model of undergraduate education based on a one to one relationship between a student and a patient with cancer has become a core module within the University of Wales College of Medicine undergraduate curriculum. The project combines the powerful impact of a one to one interaction with an active investigative and reflective approach to issues triggered from that patient's cancer journey. The aim is to provide each medical student with an understanding of the impact of a malignant disease and its treatment on patients and their families through the experience of one patient with cancer. The benefits of the project cover the areas of attitudes, skills and knowledge. Students are assessed on their involvement with the patient, in tutorials and on their portfolio, in which they record all aspects of the project. Student evaluations indicate high levels of appreciation of the project, despite its potentially strong emotional content.

RESUMO

Complementary therapies have found increasing vogue in the management of patients with cancer, although little formal evaluation has been undertaken. We report on our experience of offering hynotherapy to palliative care outpatients in a hospice day care setting. During 2 1/2 years, 256 patients had hypnotherapy, all singly; two-thirds (n = 104) were women. Only 13% (n = 21) had four or more treatment sessions. At the time of survey, the 52 patients still alive were mailed an evaluation sheet, of whom 41 responded. 61% reported improved coping with their illness. 7% (n = 3) reported harmful or negative effects from hypnotherapy. Amongst those whose coping was unchanged, many found the therapy a pleasant experience. 35 respondents (85%) appended positive comments to their questionnaire returns. Despite the limitations of a retrospective questionnaire, our findings suggest that hypnotherapy, used within strict guidelines in patients with advanced cancer, is a safe complementary therapy to enhance coping.
