Abstract
Preference and usability are imperfectly correlated when choice among procedures depends on anticipating cognitive difficulties. Navigation choices were explored by offering 2 routes through an on-line price catalog. The harder route never varied, but interface features of the easier route varied across readers. In Experiment 1, readers chose the easier route (82% trials) when it was visually salient but otherwise preferred the harder route from the active window. This suggested that visual factors influenced decisions. Experiment 2 equated visual factors, but choice of the easier route fell significantly when it needed an activation click. Navigating the harder route increased readers' use of an on-line notebook (i.e., people more often anticipated forgetting prices while reading). People choose easier procedures unless interface design miscues anticipated effort. Thus, usability evaluation needs to include factors influencing choices among methods.

Abstract
Small cell lung cancer (SCLC) is common in men and women, has a very poor prognosis, and is therefore a major cause of premature mortality. As such, any prospects for improved therapy are of great significance. The promise of telomerase as a therapeutic target is now close to realization with extremely encouraging preclinical studies aimed at the RNA component (hTR) of telomerase. The rational integration of telomerase therapeutics into clinical trials will therefore require tumours to be well characterized for hTR expression. Despite the large number of cancer types now characterized for telomerase or telomerase component gene expression, only a handful of SCLC samples have been analysed. Given the major clinical problem with treating SCLC, we specifically set out to address the issue of hTR expression in neuroendocrine tumours. Our study covers 91 pulmonary neuroendocrine tumours (62 SCLC and 29 carcinoid tumours). We present data to show that upregulation of the RNA component of telomerase occurs in 98% of human SCLCs. Interestingly, the less aggressive carcinoid tumours of the lung had a significantly lower frequency of hTR expression (P < 0.01). Importantly, we compare hTR expression in this series to the well characterized biological targets p53 and BCL2, and show hTR to be expressed more frequently. Therapies directed at the RNA component of human telomerase are in active development and these data show SCLC to be a prime target for such therapies.

Abstract
Current practice and outcome for patients with lung cancer were determined by retrospective case note review of a random sample of all lung cancer cases registered for a calendar year and augmented by review of all surgical and radical radiotherapy cases. A total of 262 patients - 231 patients less than 75 years of age and 31 patients more than 75 years of age - represented 83% of the random sample. Eighty-three per cent of patients were seen within 2 weeks of referral. One-third reported symptoms occurring for less than 1 month and one-third had experienced symptoms for more than 3 months. The median time interval from first hospital contact until the making of a management decision was 18 days. The median interval from first contact to surgery was 63 days, and to starting radical radiotherapy 70 days. Histological confirmation was obtained in 69% of patients. Ten per cent of all lung cancer patients were calculated to have received chemotherapy. Five per cent of the whole cohort had definitive surgery and 64% of these were judged to be free of the disease at 3 years. Overall survival was 9% at 3 years, with no differences relating to cell type or area of residence. Many areas of good practice have been identified, but the lack of tumour staging or performance status data, the low proportion receiving chemotherapy or definitive surgery and the poor outcome after radical radiotherapy indicate the need for prospective audit and feedback of results. The long time interval from management decision to surgery and radiotherapy suggests organizational issues which need attention.

Abstract
There is recent evidence that the inflammatory response may be important in the disproportionate loss of body cell mass in cancer patients. To examine this further, 18 male patients with lung or gastrointestinal cancer were studied over a 12-week period. In addition to weight, anthropometry, C-reactive protein (marker of the inflammatory response), albumin, and total body potassium were measured at baseline and 12 weeks. When those patients who lost total body potassium were compared with those who had not, there was a significant increase in the baseline and 12-week C-reactive protein concentrations (p < 0.05). The reduction in total body potassium was also associated with a reduction in triceps skinfold thickness (p < 0.05). There were significant correlations between the mean C-reactive protein concentration and the relative (r = -0.846, p < 0.001) and absolute (r = -0.806, p < 0.001) change in total body potassium over the follow-up period. This study demonstrates the association of a chronic inflammatory response with the rate of loss of body cell mass observed in cancer patients.

Abstract
The aim of this study was to develop a structured approach to the reporting and in particular the clinical interpretation of ventilation/perfusion (V/Q) scan results. An initial audit indicated that there were significant variations in the clinical management of patients particularly after a non-diagnostic V/Q scan report. There were also differences in the approaches used to interpret the scan itself. In an attempt to improve this, a set of interpretation guidelines was produced based on the revised PIOPED data. To combat the problems with clinical interpretation, a standard method for assessing the pre-test clinical probability of pulmonary embolism was established. This clinical risk was then combined with the V/Q scan result to give an overall probability for the presence of pulmonary embolism. The more precise risk stratification which resulted allowed explicit clinical advice on patient management to be incorporated into the final report. A second audit was performed with the revised methodology in place. The level of inter-observer variability for scan reporting decreased from 30% to 12%. The prior assessment of clinical risk and the standardized method of combining this with the scan result led to an improvement in patient management. This was particularly true for the non-diagnostic group, in whom additional investigations were more appropriately used. A structured approach which allows the pre-test probability of pulmonary embolism to be combined in an explicit fashion with the V/Q scan result can provide a more precise risk stratification allowing appropriate recommendations to be made. Such an approach can result in improved patient management.

Abstract
Twenty-seven patients with non-small cell lung cancer were recruited into a phase II study of single-agent vinorelbine using a 25 mg/m(2) weekly dose schedule. All patients were inoperable (stage III disease - 11 patients; stage IV disease - 16 patients). Median age was 64 years (range: 37-72 years). Histological sub-types were squamous cell carcinoma (15 patients), adenocarcinoma (8) and large cell carcinoma (4). Partial response was documented in 4 (16%) of 25 evaluable patients, and stable disease in 13 (52%) patients. Median duration of response was 6.5 months (range 3-16 months) and median overall survival for patients with stable disease/partial response was 8 months (range 1-20 months). Vinorelbine was generally well tolerated although WHO grade 3/4 toxicity was noted for lethargy, constipation, alopecia (2 patients each), headache and non-tumour related bone pain (1 patient each). Vinorelbine is a moderately active single-agent in non-small cell lung cancer and is currently undergoing evaluation as part of combination chemotherapy regimens.

Abstract
An investigation was carried out to examine what quality of life means to lung cancer patients. 200 patients with either lung cancer (108) or chronic respiratory disease (92) were interviewed using a short open-ended questionnaire. They were asked to define quality of life in general, identify what they considered to be a good quality of life for themselves and to rank the relative importance attached to each nominated item. A content analysis was carried out and patients' responses were categorised into eight items. These were: ability to do what one wants to do/work, enjoyment of life, family life, financial security, happiness, health, living longer and social life/leisure activities. Of these, health (42%), enjoyment of life (25%) and family life (24%) were the three most nominated items as definition of quality of life in general. Patients perceived a good quality of life for themselves differently. Family life (58%), health (51%) and social life (43%) were found to be the most nominated components of a good quality of life for the patients. Overall, patients ranked family life and health as the first or second most important factors. There were no significant differences between cases and controls. The study results are challenging and serve to remind us that the term quality of life is misused in many studies. Most existing measures do not encompass the wider aspects of quality of life identified here, but rather concentrate on the "health-related" aspects of quality of life. To achieve this, the research into the best ways of measuring and assessing quality of life must continue to seek individual values and preferences and how these can be applied in a simple way in clinical studies.

Abstract
A case-control study of quality of life in patients with lung cancer was carried out. The investigation was conducted by means of a series of interviewer-administered instruments. As part of the study, patients' attitudes towards the interviewer-administered questionnaires were studied. Previously we reported that a high proportion of the patients found being interviewed acceptable. The present study firstly examines why patients found being interviewed acceptable and secondly investigates whether there is an association between gender, age, diagnosis, place of interview, patients' overall health status, global quality of life and patients' feelings. Two hundred and thirty-two patients attending an outpatient clinic with either lung cancer or chronic respiratory disease were interviewed by means of a short questionnaire. They were asked to indicate their feelings about interviews, and to explain the reasons why they had their particular feelings. We documented issues on communication between interviewers and patients. These include observations on interviewing cancer patients, interviewing at home, and interviewing in the clinic. Nearly all the patients (96%) indicated that they found being interviewed acceptable. A content analysis of data showed that patients' feelings can be attributed to four major themes: the interview was not disturbing, they felt relaxed and at ease, they liked to talk, and the interview was conversational. There were no significant association between gender, age, diagnosis (cases and controls), place of interview, patients' overall health status and global quality of life and the reasons expressed. Practical experience from interviewing patients at home or in the clinic reveals several issues on communication between interviewer and patients. The study results suggest that apart from communication factors, other parameters such as age, gender, diagnosis, overall health status and quality of life and interview setting do not have significant role in patients' feelings about interviews. If data on quality of life studies are to be collected by interviewers, then proper communication is essential. How to achieve this remains a major question.

Abstract
Markers of the inflammatory response, interleukin 6, C-reactive protein, albumin and full blood count, were measured in non-small-cell lung cancer (NSCLC) patients (n = 21) with and without weight loss ( > 5%). There were significant increases in circulating C-reactive protein (P < 0.001), interleukin 6 (P < 0.01) and platelets (P < 0.01) in the weight-losing group. Moreover, there was a statistically significant correlation (r = 0.785, P < 0.001) between interleukin 6 and C-reactive protein concentrations. These results are consistent with interleukin 6 and the acute phase response promoting weight loss in NSCLC.

Abstract
As part of a project on quality of life in patients with lung cancer, an investigation was carried out to examine how patients reacted to the study. A group of 82 patients attending a chest clinic were interviewed by means of a short questionnaire. They were asked to indicate whether an interview was preferable to filling in a questionnaire and whether a home visit was preferable to a clinic interview, and their feelings about interviews. In addition, we documented our observations during the study period. All patients agreed to participate in the study, of whom, 56 patients (68%) preferred to be interviewed, 8 (10%) preferred to fill in a questionnaire by themselves, and the remaining 18 (22%) expressed no preference. Forty-one patients (50%) preferred to be interviewed at their homes, 13 (16%) in the clinic, and 28 (34%) expressed no preference. Nearly all patients (96%) indicated that they found being interviewed very or quite comfortable. Our observations indicated that patients were pleased to talk about and discuss their perceived cultural and social values or daily life experiences. The findings suggest that, despite the strenuous attempts by clinicians to deliver effective health care, proper communication with patients remains limited. The finding has some implications for community care.

Abstract
PURPOSE Recombinant human erythropoietin (r-Hu-EPO) is known to be effective in untreated cancer patients. Here we assess the possibility that r-Hu-EPO may also prevent or reduce anemia in patients who receive cytotoxic chemotherapy. METHODS Thirty-six patients with small-cell lung carcinoma (SCLC) were enrolled onto a three-arm, randomized trial to investigate the effect of r-Hu-EPO on hemoglobin (Hb) levels and RBC and platelet (Plt) transfusions during chemotherapy. Bone marrow progenitors were studied before and after treatment. Two groups of patients received r-Hu-EPO at a dose of either 150 IU/kg (group 150) or 300 IU/kg (group 300) three times per week for the duration of chemotherapy. A control group did not receive r-Hu-EPO (group O). A maximum of six cycles of a chemotherapy regimen that consisted of vincristine, ifosfamide, carboplatin, and etoposide (VICE) were given to all patients. Hematologic parameters were measured weekly, and RBC or Plt transfusions were given for Hb levels less than 9 g/dL and Plt counts less than 20 x 10(9)/L. RESULTS Hb levels decreased in all patients, but onset of anemia was delayed in groups that received r-Hu-EPO (P = .002). A total of 116 U RBC were transfused in group 0, 54 in group 150, and 52 in group 300 (P = .017). In addition, there was a nonsignificant trend toward higher Plt counts and fewer Plt transfusions in patients who received r-Hu-EPO. CONCLUSION r-Hu-EPO at a dose of either 150 or 300 IU/kg three times weekly delays the onset of anemia and reduces RBC transfusion requirements in patients who undergo intensive chemotherapy for SCLC. A possible effect of r-Hu-EPO on platelet numbers deserves further study.
