The total costs (direct and indirect) associated with the operation of an Australian community based screening programme for colorectal cancer (CRC) were estimated. One-year costs of the programme were estimated to be AUS$1 347 948 to screen 24 000 participants. This corresponded to AUS$8868 per polyp and AUS$28 679 per cancer detected. The results presented here are quite favourable compared with the only other Australian screening programme that has reported costs. That programme estimated a cost per cancer detected of AUS$24 233 (adjusted). The recent Australian public health literature has been almost unanimously against recommending the operation of population based CRC screening programmes. More recently, overseas randomized control trials have reported reduced mortality (15 to 33%) as a result of these programmes. Cost data, as presented here combined with the epidemiological evidence, indicate the challenge the Federal Government is now confronted with in formulating policy to control the increasing number of deaths from the disease. 相似文献

目的:检测B7基因在肾细胞癌的表达及其与肾细胞癌分级、分期及预后的关系。方法:本文应用RTPCR和免疫组织化学技术检测了22例肾细胞癌组织B7的表达。结果:RTPCR5例阳性,免疫组化4例阳性,B7mRNA表达与肾癌病理分级、分期无关系;病理切片HE染色显示,B7阳性肿瘤组织内淋巴细胞浸润明显增多。结论:表达B7的肿瘤组织局部抗肿瘤免疫反应增强,提示B7表达可能与肿瘤预后有关。大部分泌尿系肿瘤不表达B7,为转B7基因治疗泌尿系肿瘤提供了理论依据。 相似文献

The reasons why older people smoke have not been examined in the literature. This paper attempted to examine the differences in motivation and maintenance factors of elderly and young smokers using the Horn-Waingrow Why do you smoke questionnaire. One hundred and thirteen clinical patients and 112 non-patient controls were used in this study. The clinical group was divided into an elderly group (n = 58) and a younger group (n = 55). The results of a discriminant analysis showed that patients significantly differed from non-patients on 'automatic habit and stimulation', and 'crutch/tension reduction' factors. Elderly patients were found to be significantly differentiated from both younger patients and the control group on the 'pleasurable relaxation' factor. These findings offer support for the US Surgeon Generals' report that elderly smokers do have different motivating factors for their smoking behaviours from younger smokers. 相似文献

The purpose of this study was to prospectively examine the effectiveness and tolerability of a simple radiotherapy technique for the palliation of symptomatic liver metastases. Twenty‐eight patients with symptomatic liver metastases were enrolled from seven centres, and received targeted (partial or whole) liver irradiation consisting of 10 Gy in two fractions over 2 days. Symptoms at baseline were hepatic pain (27 patients), abdominal distension (19), night sweats (12), nausea (18) and vomiting (eight). Twenty‐two patients (76%) had failed previous treatment with chemotherapy, hormonal therapy and/or high‐dose steroids. Symptoms and potential toxicities were prospectively assessed at the time of treatment, then 2, 6 and 10 weeks later. Individual symptom response rates were 53?66% at 2 weeks. Partial or complete global symptomatic responses were noted in 15 patients (54%) overall. The treatment was well tolerated with two patients (7%) experiencing grade 3 toxicity (one vomiting and one diarrhoea); however, four patients reported temporary worsening of pain shortly after treatment. This simple and well‐tolerated treatment achieves useful palliation. 相似文献

pattern of anterolateral myocardial infarction. Angiography revealed normal coronary arteries and moderate mitral regurgitation.

Aberrant crypt focus promotion and glucose intolerance: correlation in the rat across diets differing in fat, n-3 fatty acids and energy 总被引:1,自引:0,他引:1

McKeown-Eyssen (Cancer Epidemiol. Biomarkers Prevent., 3, 687-695, 1994)
and Giovannucci (Cancer Causes Control, 6, 164-179, 1995), noting the
striking similarity in lifestyle risk factors for colorectal cancer and
insulin resistance, proposed that the hyperinsulinemia, glycemia and
hypertriglyceridemia associated with insulin resistance promotes colon
cancer. To compare the effect of diet on colon cancer promotion and insulin
resistance in the F344 rat, we assessed the effect of fat, n-3 fatty acids
and energy in pairwise comparisons on average size of aberrant crypt foci
(ACF) and on glucose intolerance in the same animals in a single
experiment. Diets high in fat and energy increased and diets with increased
n-3 fatty acids and calorie restriction decreased both ACF growth and
glucose intolerance compared with control diets. The measures of promotion
of colon cancer and insulin resistance were strongly correlated (n = 98, r
= 0.67, P < 0.001). In addition, both were highly correlated with daily
energy intake (r = 0.62 and 0.66) and were also correlated with basal
(post-prandial) insulin, glucose and triglycerides (r = 0.31-0.53, P <
0.01). We concluded that ACF growth and glucose intolerance are correlated
for a wide range of diets and that increased circulating energy (glucose
and triglycerides) may lead to both colon cancer promotion and insulin
resistance.

Breast cancer in a 6-year-old child 总被引:2,自引:0,他引:2
A 6-year-old girl presented for a second opinion with a 1-year history of an enlarging soft tissue mass just lateral to the right areola. She had been seen by a pediatric surgeon elsewhere who reassured the parents that the lesion was benign. Ultrasound scan showed a 1.5- x 1.5-cm cystic structure adjacent to the right breast bud. Excisional biopsy results showed secretory ductal adenocarcinoma. Modified radical mastectomy with axillary node dissection was performed. All 11 nodes were negative for metastatic disease. She is now disease free 3 years after diagnosis. Estrogen-progesterone receptors were negative, as was screening for BCR 1 and 2. This is the first report of cytogenetics showing an abnormal cell line with a reciprocal translocation between 12p and 15q. Although breast cancer is extremely rare in children, a history of a painless, enlarging, firm breast mass should raise concern about possible neoplastic disease. Cystic appearance on ultrasound scan caused by the pseudocapsule around the tumor may be a marker for secretory carcinoma. Histological evaluation of all suspicious masses should be obtained. Because of the risk of local recurrence and axillary metastases, the authors recommend modified radical mastectomy with axillary node dissection for children with secretory carcinoma of the breast. 相似文献
