Management of lung nodules detected by volume CT scanning.

BACKGROUND: The use of multidetector computed tomography (CT) in lung-cancer screening trials involving subjects with an increased risk of lung cancer has highlighted the problem for the clinician of deciding on the best course of action when noncalcified pulmonary nodules are detected by CT. METHODS: A total of 7557 participants underwent CT screening in years 1, 2, and 4 of a randomized trial of lung-cancer screening. We used software to evaluate a noncalcified nodule according to its volume or volume-doubling time. Growth was defined as an increase in volume of at least 25% between two scans. The first-round screening test was considered to be negative if the volume of a nodule was less than 50 mm(3), if it was 50 to 500 mm(3) but had not grown by the time of the 3-month follow-up CT, or if, in the case of those that had grown, the volume-doubling time was 400 days or more. RESULTS: In the first and second rounds of screening, 2.6% and 1.8% of the participants, respectively, had a positive test result. In round one, the sensitivity of the screen was 94.6% (95% confidence interval [CI], 86.5 to 98.0) and the negative predictive value 99.9% (95% CI, 99.9 to 100.0). In the 7361 subjects with a negative screening result in round one, 20 lung cancers were detected after 2 years of follow-up. CONCLUSIONS: Among subjects at high risk for lung cancer who were screened in three rounds of CT scanning and in whom noncalcified pulmonary nodules were evaluated according to volume and volume-doubling time, the chances of finding lung cancer 1 and 2 years after a negative first-round test were 1 in 1000 and 3 in 1000, respectively.

High affective risk perception is associated with more lung cancer-specific distress in CT screening for lung cancer.

Screening for cancer can cause distress. People who perceive their risk of cancer as high may be more vulnerable to distress. This study evaluated whether participants of a lung cancer Computed Tomography (CT) screening trial with a high affective risk perception of developing lung cancer had a higher level of lung cancer-specific distress during CT screening. Furthermore, we evaluated whether participants perceived their risk of developing lung cancer differently 6 months after screening compared with 1 day before screening. A total of 351 subsequent participants of the NELSON-trial (Dutch-Belgian randomized controlled trial for lung cancer screening in high-risk subjects), who were randomized to the screen arm, were asked to fill in questionnaires 1 day before and 6 months after screening. Lung cancer-specific distress (Impact of Event Scale (IES)), generic health-related quality of life (SF-12) and affective risk perception were assessed. One day before screening, the participants with a high affective risk perception (n=47/321, 14.6%) had significantly higher (i.e., worse) median IES scores than participants with a low affective risk perception (11.5 vs. 2.0, p<0.01). Although median IES scores were significantly lower 6 months after screening than 1 day before screening, participants with a high affective risk perception still showed significantly higher IES scores than participants with a low affective risk perception (6.5 vs. 1.0, p<0.01). Six months after screening, significantly less participants (10.5%) felt that their risk of developing lung cancer was high than 1 day before screening (14.5%) (p<0.01). Levels of distress were not severe, but were elevated compared to participants with a low affective risk perception, and therefore, attention for this group is recommended.

The effectiveness of a computer-tailored smoking cessation intervention for participants in lung cancer screening: a randomised controlled trial.

BACKGROUND: Lung cancer screening might be a teachable moment for smoking cessation intervention. The objective was to investigate whether a tailored self-help smoking cessation intervention is more effective in inducing smoking cessation compared to a standard brochure in male smokers who participate in the Dutch-Belgian randomised controlled lung cancer screening trial (NELSON trial). METHODS: Two random samples of male smokers who had received either a standard brochure (n=642) or a tailoring questionnaire for computer-tailored smoking cessation information (n=642) were sent a questionnaire to measure smoking behaviour two years after randomisation. RESULTS: Twenty-three percent of the male smokers in the tailored information group returned a completed tailoring questionnaire and thus received the tailored advice. The prolonged smoking abstinence was slightly, but not statistically significant, lower amongst those randomised in the tailored information group (12.5%) compared with the brochure group (15.6%) (OR=0.77 (95%-CI: 0.56-1.06). The level of education and intention to quit smoking significantly predicted smoking cessation at follow-up (p<0.05). The majority of the respondents did not recall whether and which smoking cessation intervention they had received at randomisation after 2-years of follow-up. CONCLUSION: The current study showed no advantage of tailored smoking cessation information over standard self-help information amongst male smokers with a long term smoking history who participate in a lung cancer screening trial after two years of follow-up. However, the low percentage participants who actually received the tailored advice limited the ability to find an advantage.

Informed decision making does not affect health-related quality of life in lung cancer screening (NELSON trial).

BACKGROUND: It is believed that making an informed decision about (screening) participation is associated with better health-related quality of life (HRQoL) outcomes. This is the first study in cancer screening to explore this association in subjects participating in a lung cancer computed tomography (CT) screening trial. METHODS: Participants that made either an informed decision to participate (n = 155) or not (n = 133) were selected for this study. Differences in HRQoL, measured as generic HRQoL (Short Form 12 [SF-12] and EuroQol questionnaire [EQ-5D]), anxiety/distress (State-Trait Anxiety Inventory [STAI-6], Impact of Event Scale [IES] and Consequences of Screening-Lung Cancer [COS-LC]), were tested with Mann-Whitney U tests and ANOVA at three assessment points (when deciding about participation, before trial randomisation and 2 months after receiving the CT result). RESULTS: Subjects who made an informed decision to participate had no better scores than those who did not make an informed decision for 23 out of 24 HRQoL comparisons, except for a better mean score for mental health (Mental Component Summary (MCS) = 53.9 ± 9.2 versus 51.0 ± 10.1, p = 0.003) before randomisation. For subjects with an indeterminate CT result (n = 64), no significant differences were found between subjects with (n = 35) or without (n = 29) an informed decision. CONCLUSION: Subjects who did not make an informed decision to participate in lung cancer CT screening trial did not experience worse HRQoL during screening than subjects who did make an informed decision, either in general or after receiving an indeterminate result.

The influence of work and treatment related factors on clinical status and disability in patients with non-specific work-related upper limb disorders.

OBJECTIVE: To assess the influence of work- and treatment-related factors on clinical status and functional disability in patients with non-specific work-related upper limb disorders (WRULD). PARTICIPANTS: 182 computer workers with non-specific WRULD, 18-50 years old, not having specific WRULD nor incomplete medical records. METHODS: Retrospective cohort study among computer workers with non-specific WRULD; average follow-up 4 years. Medical records at time of diagnosis and during treatment period and a follow-up questionnaire were used. SETTING: Outpatient department of Rehabilitation Medicine, University Hospital Maastricht. OUTCOME MEASURES: Non-specific WRULD (clinical status) and Disabilities of Arm, Shoulder and Hand (DASH) at follow-up. RESULTS: 103 patients (57%) returned the questionnaire. Of these, 14% developed a chronic pain syndrome, 9% recovered, 77% worsened slightly. None of the selected work- and treatment-related factors were significantly associated with clinical status. "Number of working hours per week before diagnosis" was negatively (b=-0.66, p=0.00) and "other therapies during treatment" (b=8.76, p=0.02) positively associated with DASH. CONCLUSIONS: Computer workers with non-specific WRULD have a poor prognosis. Working more hours before diagnosis seems not predictive for disability while having undergone other therapies during treatment period does. Prospective cohort studies are recommended to unravel the associations found.

Impact of computed tomography screening for lung cancer on participants in a randomized controlled trial (NELSON trial).

BACKGROUND: Computed tomography (CT) screening is an important new tool for the early detection of lung cancer. In the current study, the authors assessed the discomfort associated with CT scanning and the subsequent wait for results and health-related quality of life (HRQoL) over time. METHODS: A total of 351 participants in the Dutch-Belgian randomized controlled trial for lung cancer screening in high-risk subjects (the NELSON trial) who had an appointment for a baseline CT scan were asked to complete questionnaires regarding their experienced discomfort and HRQoL before, 1 day after, and approximately 6 months after the CT scan. HRQoL was measured as generic HRQoL (12-item Short Form [SF-12] and EuroQol questionnaire [EQ-5D]), generic anxiety (State-Trait Anxiety Inventory [STAI-6]), and lung cancer-specific distress (Impact of Event Scale [IES]). Approximately 76.9% of the participants completed all 3 questionnaires. RESULTS: Approximately 87% to 99% of participants reported experiencing no discomfort related to the CT scan. The median SF-12, EQ-5D, STAI-6, and IES scores did not appear to change relevantly over time. Approximately 46.0% and 51.3%, respectively, of the participants reported discomfort in connection with having to wait for the results of the CT scan and dreading those results. These patients had relevantly higher STAI-6 and IES scores (P < .01) (unfavorable) at all 3 assessments. CONCLUSIONS: The current evaluation of the potential adverse effects of CT screening for lung cancer on HRQoL demonstrated no negative effects. However, waiting for the CT scan results was reported to be discomforting by approximately half of the participants. Minimizing the waiting time for the test results is therefore recommended.
