The silent epidemic: tobacco and the evolution of lung cancer and its treatment

Patterns of Symptom Distress in Adults Receiving Treatment for Lung Cancer

Knowledge of the patterns of symptom distress in adults receiving treatment for lung cancer is an important first step in developing interventions that can potentially lessen symptom distress. The purposes of this secondary analysis were to describe the changes in patterns of symptom distress over time in adults receiving treatment for lung cancer, and to examine the relationship of selected demographic and clinical characteristics to symptom distress. Complete data were available for 117 patients. The patterns of symptom distress in adults receiving treatment for lung cancer varied between treatment groups and over time. Symptom distress scores were moderate to high on entry into the study, indicating that symptom management in newly diagnosed lung cancer patients is essential and should begin early in the course of illness. Moreover, clinical interventions should be tailored to the type of treatment. Various demographic and clinical variables were weak and inconsistent predictors of symptom distress, underscoring the importance of examining the role of psychosocial factors in mediating symptom distress.

Overweight, physical activity, tobacco and alcohol consumption in a cross-sectional random sample of German adults

Background

There is a current paucity of data on the health behaviour of non-selected populations in Central Europe. Data on health behaviour were collected as part of the EMIL study which investigated the prevalence of infection with Echinococcus multilocularis and other medical conditions in an urban German population.

Methods

Participating in the present study were 2,187 adults (1,138 females [52.0%]; 1,049 males [48.0%], age: 18–65 years) taken from a sample of 4,000 persons randomly chosen from an urban population. Data on health behaviour like physical activity, tobacco and alcohol consumption were obtained by means of a questionnaire, documentation of anthropometric data, abdominal ultrasound and blood specimens for assessment of chemical parameters.

Results

The overall rate of participation was 62.8%. Of these, 50.3% of the adults were overweight or obese. The proportion of active tobacco smokers stood at 30.1%. Of those surveyed 38.9% did not participate in any physical activity. Less than 2 hours of leisure time physical activity per week was associated with female sex, higher BMI (Body Mass Index), smoking and no alcohol consumption. Participants consumed on average 12 grams of alcohol per day. Total cholesterol was in 62.0% (>5.2 mmol/l) and triglycerides were elevated in 20.5% (≥ 2.3 mmol/l) of subjects studied. Hepatic steatosis was identified in 27.4% of subjects and showed an association with male sex, higher BMI, higher age, higher total blood cholesterol, lower HDL, higher triglycerides and higher ALT.

Conclusion

This random sample of German urban adults was characterised by a high prevalence of overweight and obesity. This and the pattern of alcohol consumption, smoking and physical activity can be considered to put this group at high risk for associated morbidity and underscore the urgent need for preventive measures aimed at reducing the significantly increased health risk.

Cigarette smokers views on their habit and the causes of their illness following lung cancer diagnosis: a clinical-qualitative study

CONTEXT AND OBJECTIVE

Lung cancer is the commonest malignant tumor and is increasing in incidence by 2% a year. In 90% of diagnosed cases, it is associated with tobacco product consumption. It is the greatest cause of mortality among cancer types in Brazil. Knowledge of patients psychological representations is needed for evaluating treatments and educating patients. The aim here was to interpret how smokers with lung cancer interpret the possible causes of their illness and to understand their perceptions regarding cigarette use.

DESIGN AND SETTING

Clinical-qualitative study (exploratory, non-experimental) at the Pulmonary Disease Service, General Hospital, Universidade Estadual de Campinas.

METHODS

An intentional small sample of cancer inpatients was recruited. The group was closed with 11 subjects, following attainment of data saturation from interviews. These interviews were semi-directed, with in-depth open-ended questions on interviewees observations, applied in a confidential setting using a tape recorder. Interviewees responses were categorized using qualitative content analysis and the results were assessed using interdisciplinary theoretical concepts, particularly from medical psychology.

RESULTS

Six males and five females aged between 46 and 68 years who presented diverse clinical conditions were interviewed.

CONCLUSIONS

A broader approach towards the psychological comprehension of such patients is needed, considering that cigarette consumption involves conscious and unconscious motivations, sociocultural and educational factors, the glamour of tobacco advertising, and problems with psychophysical dependence. Such an approach would avoid the perception among patients that the healthcare team are "inquisitors". This would lead to better adherence to treatment and better quality of life.

Harmful health effects of cigarette smoking

This is a comprehensive review on the harmful health effects of cigarette smoking. Tobacco smoking is a reprehensible habit that has spread all over the world as an epidemic. It reduces the life expectancy among smokers. It increases overall medical costs and contributes to the loss of productivity during the life span. Smoking has been shown to be linked with various neurological, cardiovascular, and pulmonary diseases. Cigarette smoke not only affects the smokers but also contributes to the health problems of the non-smokers. Exposure to environmental tobacco smoke contributes to health problems in children and is a significant risk factor for asthma. Cigarette smoke contains several carcinogens that alter biochemical defense systems leading to lung cancer.

Symptom prevalence, distress, and change over time in adults receiving treatment for lung cancer

Adequate management of symptoms in adults with lung cancer is an important focus for clinical interventions. Knowledge of symptom prevalence and distress can be used to develop empirically based interventions that can potentially reduce distressing symptoms and improve quality of life. The purposes of this study were to describe which symptoms are most distressing, describe the prevalence of symptoms in adults receiving treatment for lung cancer, identify how symptoms change over time, and identify patient-related and clinical characteristics related to symptom distress. Data were available from 117 patients. Fatigue and pain were the most distressing symptoms for each group and at each time. Significant differences in distressing symptoms among the treatment groups were noted for nausea, fatigue, bowel pattern, and concentration at entry into the study and difficulty with appetite at 6 months. Many of the individual symptoms demonstrated a decrease in distress from 0 to 3 months and then an increase in distress levels from 3 to 6 months. Many of the individual symptoms were associated with demographic covariates and treatment group values but no consistent pattern emerged over time except for baseline symptom distress. Symptom distress at entry to the study was a strong predictor of nine distressing symptoms at 3 months and seven distressing symptoms at 6 months. Questionnaires such as the SDS may be useful as screening instruments to target those who need more intensive interventions.
