Survival outcome of care by specialist surgeons in breast cancer: a study of 3786 patients in the west of Scotland.

OBJECTIVE: To compare survival outcome for patients with breast cancer cared for by specialist and non-specialist surgeons in a geographically defined area. DESIGN: Retrospective study of all female patients aged under 75 years in the area treated between 1980 and June 1988 (before breast screening began). Patients were identified from the cancer registry and from pathology records of all hospitals in the area. Specialist surgeons were identified by one author. All other surgeons caring for patients from the area were considered non-specialists. SETTING: A geographically defined population in urban west of Scotland. SUBJECTS: 3786 patients with histologically verified breast cancer operated on between 1 January 1980 and 30 June 1988 and followed to 31 December 1993. MAIN OUTCOME MEASURES: Five and 10 year survival rates for specialists and non-specialists; relative hazard ratios derived from Cox's proportional hazards model adjusted for prognostic factors--age, socioeconomic status, tumour size, and nodal involvement. RESULTS: The five year survival rate was 9% higher and the 10 year survival 8% higher for patients cared for by specialist surgeons. A reduction in risk of dying of 16% (95% confidence interval 6% to 25%) was found after adjustment for age, tumour size, socioeconomic status, and nodal involvement. The benefit of specialist care was apparent for all age groups, for small and large tumours, and for tumours that did and did not affect the nodes and was consistent across all socioeconomic categories. CONCLUSIONS: Survival differences of the magnitude demonstrated have implications for the provision of services for the treatment of women with breast cancer. There is a need to improve equity in the treatment of breast cancer.

Quality of life in patients with ovarian cancer: current state of research.

Ovarian cancer is the most malignant cancer in women, where it is the fifth leading cause of cancer-related death. The disease and its treatment have considerable effects on the quality of life of patients with this cancer. This study reviews existing literature on quality of life in patients with ovarian cancer to demonstrate the importance of the topic, to comment on improvements achieved and to consider their implications for the implementation of optimal treatment. A literature search was carried out through MEDLINE and of published papers on quality of life in patients with ovarian cancer from 1976 to 1994. Twenty papers have been reviewed, of which, 10 were treatment-related assessments of quality of life and the remaining 10 dealt with different topics including psychometric issues in measuring health-related quality of life. Twenty-four instruments were employed to measure quality of life. Of these, the Rotterdam Symptom Checklist (RSCL) and The European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) were found to be the most appropriate. Although meta-analysis of results is impossible, it appears that debulking surgery followed by platinum-based chemotherapy could improve both quality of life and survival. In addition to effective and efficient treatment, psychological counselling, palliative and home care, nutritional support and pain relief are the most important areas for improving quality of life of patients with ovarian cancer. Knowledge and insight into the quality of life of patients with ovarian cancer are still limited, and a large carefully planned international study is required. Use of existing standard measures is preferable and agreement should be reached on a selected single instrument.

Understanding patients: let's talk about it. A study of cancer communication.

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.

Interviewing cancer patients in a research setting: the role of effective communication.

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.

Quality of life: perception of lung cancer patients.

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.

Measuring quality of life in oncology: is it worthwhile? I. Meaning, purposes and controversies.

This is the first of a two-part paper on quality of life in cancer patients. This part examines some of the fundamental issues in health-related quality of life measurement with particular attention being given to cancer medicine, thus helping to focus the direction and methodological rigour required in future investigations. Relevant topics are discussed to illustrate the importance of quality of life measures in cancer care. A perspective on the meaning of "outcome' and "quality of life' are presented to demonstrate the controversies that exist in the field. It is concluded that despite methodological limitations, quality of life measures have a potential role in advancing cancer care.

Measuring quality of life in oncology: is it worthwhile? II. Experiences from the treatment of cancer.

This is the second part of the paper on quality of life in cancer patients which appeared in this journal (Montazeri et al., 1996a). In this part experiences from the treatment of cancer are given and relevant literature is reviewed. Several topics have been covered, including new directions and methods in assessing quality of life. It is argued that in a chronic condition, adding life to years instead of years to life is an important task. Adding years to life may prolong survival, but whether this is to the benefit of patients is debatable. Considering patients' views, their values and preferences may improve the quality of care and at the same time, reduce the psychological distress and physical discomfort in patients with cancer. It is concluded that quality of life measures have considerable potential in this challenging issue.

Cardiorespiratory disease in men and women in urban Scotland: baseline characteristics of the Renfrew/Paisley (midspan) study population.

UNLABELLED: STUDY OBJECTIVE. To describe the distribution of risk factors, risk behaviors, symptoms and the prevalence of cardiorespiratory disease in men and women in an urban area with high levels of socioeconomic deprivation. A cross-sectional survey of 15,411 men and women aged 45-64, comprising an 80% response rate from the general population in Paisley and Renfrew, Scotland. MAIN RESULTS: The main characteristics of the male Renfrew/Paisley population, compared to previous British studies, were shorter stature, higher blood pressure, a higher proportion of smokers who continue to smoke, lower FEV1 and higher levels of reported angina, breathlessness on effort and chronic bronchitis. In comparison with men, the main characteristics of the female Renfrew/Paisley population were shorter stature, higher plasma cholesterol, lower FEV1, fewer current and ex-smokers, and a higher prevalence of breathlessness on effort. There were only small differences between men and women in the prevalence of angina, ECG evidence of myocardial ischaemia and chronic bronchitis. CONCLUSIONS: Middle-aged men and women in an urban area with high levels of socio-economic deprivation have different cardio-respiratory risk and disease profiles compared to previous population in the UK, based on occupational groups and random national samples.

Risk factors for cardiorespiratory and all cause mortality in men and women in urban Scotland: 15 year follow up.

STUDY OBJECTIVE: To describe the relationship between risk factors, risk behaviours, symptoms and mortality from cardiorespiratory diseases in an urban area with high levels of socioeconomic deprivation. A cohort study of 15,411 men and women aged 45-64, comprising 80% of the general population of Paisley and Renfrew, Scotland. OUTCOMES: Mortality after 15 years from coronary heart disease(ICD 410-4), stroke(ICD 430-8), respiratory disease(ICD 460-519) and all causes. MAIN RESULTS: Mortality rates from all causes were 19% in men aged 45-49, 31% in men aged 50-54, 42% in men aged 55-59 and 57% in men aged 60-64. The rates are considerably higher than those reported in previous UK prospective studies. For women the rates were 12%, 18%, 25% and 38% respectively. In general men and women showed similar relationships between risk factor levels and mortality rates. People in manual occupations had higher mortality rates. Raised levels of systolic and diastolic blood pressure were associated with increased coronary, stroke and all cause mortality rates. Plasma cholesterol had no such association with all cause mortality rates. High and low levels of body mass index were associated with higher mortality rates than intermediate levels. A relationship between short stature and increased mortality rates was observed in men and women. FEV1 expressed as a percentage of the expected value showed the strongest relationship with mortality rates, particularly for respiratory disease, but also for deaths from coronary heart disease, stroke and all causes. CONCLUSIONS: A similar pattern of relationship between risk factor levels and mortality rates exists in men and women in Renfrew and Paisley. Respiratory impairment as measured by FEV1% predicted appears to be the most likely explanation of the observed high all cause mortality rates in this population.

Management of ovarian cancer: referral to a multidisciplinary team matters.

Differences in survival outcome for patients with ovarian cancer in Scotland led to an investigation of whether these differences were due to variation in presenting prognostic features or to the organisation and delivery of cancer services. A retrospective study of all 533 cases of ovarian cancer registered in Scotland in 1987 was carried out. After adjustment for age, stage, pathology, degree of differentiation and presence of ascites, survival improved when patients (1) were first seen by a gynaecologist (P < 0.05); (2) were operated on by a gynaecologist (P < 0.05); (3) had residual disease of less than 2 cm post-operatively (P < 0.001); (4) were prescribed platinum chemotherapy (P < 0.05); and (5) were referred to a joint clinic (P < 0.001). When gynaecologists operated the likelihood of smaller residual disease increased (P < 0.001). The improved survival from management by a multidisciplinary team at a joint clinic was not solely due to the prescription of platinum chemotherapy. The results of this study support the contents of the 1991 Department of Health report on present acceptable practice in the management of ovarian cancer, circulated to gynaecologists and surgeons in Scotland in 1992. The new finding that in a common cancer management by a multidisciplinary team at a joint clinic directly affects survival requires urgent attention.

Asbestos and lung cancer in Glasgow and the west of Scotland.

OBJECTIVE: To quantify the relation between lung cancer and exposure to asbestos in men in west Scotland and to estimate the proportion of lung cancer which may be attributed to exposure to asbestos. DESIGN: An ecological correlation study of the incidence of lung cancer in men and past asbestos exposure. The unit of analysis was the postcode sector. Correction was made for past cigarette smoking, air pollution, and deprivation. SETTING: The region covered by the west of Scotland cancer registry, containing 2.72 million people and including Glasgow and the lower reaches of the River Clyde, where shipbuilding was once a major industry. SUBJECTS: All men diagnosed with lung cancer between 1975 and 1984 whose residence at the time of registration was within the west of Scotland. MAIN OUTCOME MEASURE: The population attributable risk for asbestos related lung cancer. RESULTS: An estimated 5.7% (95% confidence interval 2.3 to 9.1%) of all lung cancers in men registered in the west of Scotland during the period 1975-84 were asbestos related, amounting to 1081 cases. CONCLUSIONS: A considerable proportion of cases of lung cancer in men in Glasgow and the west of Scotland from 1975 to 1984 were asbestos related. Most of these may not have been considered for compensation by the Department of Social Security. Given the very small annual number of recorded cases of asbestosis this condition is probably not a prerequisite for the development of asbestos related lung cancer. A heightened awareness of the increasing incidence of asbestos related neoplasms and their more thorough investigation are recommended.

Management of malignant teratoma: does referral to a specialist unit matter?

The causes of geographical differences in cancer survival among regions of the UK are unclear. Population-based audit of management of patients with non-seminomatous germ-cell tumours (NSGCT) in the west of Scotland enabled us to assess the relative contributions to outcome of recognised prognostic factors, treatment centre, and protocol treatment. Data on treatment and outcome were analysed for 440 (97%) of 454 men with NSGCT diagnosed between 1975 and 1989. All but 11 patients were treated at tertiary referral centres; 235 were treated at a single unit (unit 1) and 194 at four other units (2-5). 99 men have died, 89 (20%) from NSGCT. Independent prognostic factors for NSGCT survival were extent of tumour at diagnosis (p < 0.001), 5-year period of diagnosis (from 1975-79 to 1985-89, p < 0.001), and treatment unit (unit 1 vs units 2-5, p < 0.001). Unit 1, which had the best survival rates, treated most patients overall (53%), including the majority (70%) in the worst prognostic category (poor-prognosis metastatic disease). The proportion of men receiving nationally agreed protocol treatment was higher at unit 1 than elsewhere (97 vs 61%, p < 0.0001). However, analysis restricted to men who received protocol treatment, adjusted for other important prognostic variables, still showed a survival advantage for this unit (relative death rate units 2-5 vs unit 1, 2.82 [95% CI 1.53-5.19], p < 0.001). These findings suggest that centralisation of treatment for NSGCT improves outcome; the benefit seems to be additional to any advantage resulting from protocol treatment.

Incidence of and mortality from cancer in hypertensive patients.

OBJECTIVES: To assess incidence of and mortality from cancer in hypertensive patients taking atenolol, comparing the findings with two control populations and with hypertensive patients taking other drugs. DESIGN: Retrospective analysis of patients first seen in the Glasgow Blood Pressure Clinic between 1972 and 1990. Patients' records were linked with the registrar general's data for information on mortality and with the West of Scotland Cancer Registry for information on incident and fatal cancers. Cancers were compared in patients and controls and in patients taking atenolol, beta blockers other than atenolol, and hypotensive drugs other than beta blockers. SUBJECTS: 6528 male and female patients providing 54,355 years of follow up. SETTING: Hypertension clinic in Glasgow. MAIN OUTCOME MEASURES: Observed numbers of cancers in clinic patients were compared with expected numbers derived from cancer rates in two control populations adjusted for age, sex, and time period of data collection. RESULTS: Cancer mortality was not significantly different in clinic patients as a whole and controls. Incident and fatal cancers were not significantly increased in male or female patients taking atenolol. Cancer incidence did not rise in the clinic after a large increase in prescriptions for atenolol after 1976. CONCLUSION: This analysis does not suggest a link between atenolol and cancer.

Age, socio-economic status and survival from cancer of cervix in the West of Scotland 1980-87.

The outcome of treatment by age and socio-economic status was examined for 1,588 women with invasive cancer of cervix resident in the West of Scotland and diagnosed between 1980 and 1987. There was no difference in prognosis according to either variable once analysis was controlled for stage at presentation, treatment type and tumour grade. Tumour histology, date of treatment and health board of residence had no significant effect on survival independent of other variables. A strong correlation was found between socio-economic status and the incidence of cervical cancer in the West of Scotland. Women aged 45 and over and living in deprived areas were more likely to present with later stage tumours and to survive less well than younger patients from the more affluent parts of the region. Any additional resources which may be made available for cervical cancer screening should be directed more effectively towards those most at risk.
