Lung Cancer Screening Trials

Lung cancer remains the leading cause of cancer – related death globally, with 1.8 million deaths in 2020 alone (SEMrush 2023 Study). Early detection through screening is crucial as the five – year survival rate jumps from 12 – 16% when diagnosed at an advanced stage to 60 – 70% when detected early. This has spurred numerous lung cancer screening trials.

Types of trials

Danish Lung Cancer Screening Trial (DLCST)

The DLCST is one of the important initiatives in the field of lung cancer screening. Although not as extensively discussed in the provided data as some other trials, it contributes to the overall body of research on lung cancer screening. It likely follows similar principles of using screening methods to detect lung cancer at an early stage, which can potentially improve patient outcomes.

National Lung Screening Trial (NLST)

The NLST is a landmark randomized clinical trial. It demonstrated a 20% lung cancer mortality reduction with low – dose helical computed tomography. This trial has been a cornerstone in promoting lung cancer screening. Its results provided strong evidence that early detection through low – dose CT screening can save lives. For example, many countries have used the NLST findings as a basis for considering or implementing their own screening programs. Pro Tip: When evaluating the effectiveness of a screening program, look for results similar to those of the NLST to gauge its potential impact on mortality.

Nederlands – Leuvens Longkanker Screenings Onderzoek (NELSON)

NELSON, along with NLST, indicated that low – dose CT (LDCT) screening results in a statistically significant decrease in mortality in patients. Multiple international observational studies and randomized trials, including NELSON, have confirmed the efficacy of annual LDCT in reducing lung cancer mortality, which forms the basis for current guidelines concerning lung cancer prevention and screening.

Participant recruitment

Increasing the number of participants in lung cancer screening trials is crucial for obtaining more accurate and representative results. One promising strategy is increased engagement with community – based practices. For instance, GO2 for Lung Cancer led recruitment efforts of 17 field sites from their Centers. They used three methods: Letters of Support, where pre – selected sites with past engagement submitted letters for a grant application and were then invited to join if they met eligibility; Non – Targeted Dissemination Campaign, which involved sending an ad with trial information to network members via a weekly newsletter; and Targeted Proactive Outreach Campaign, which directly contacted pre – determined eligible sites with trial information. Pro Tip: Trial organizers should consider a multi – pronged approach like GO2 for Lung Cancer to maximize participant recruitment.

Target number of participants

While the specific target number of participants for each trial can vary depending on the trial’s objectives, sample size calculations are essential. A well – defined target number ensures the trial has enough statistical power to detect meaningful differences in outcomes. For example, in a study on high – risk individuals (aged 45 – 79), 1,486 individuals were selected from the Liverpool Lung Prospective (LLP) cohort study. The target number should be based on factors such as the expected prevalence of the disease, the magnitude of the effect being studied, and the desired level of statistical significance. As recommended by industry – standard sample size calculators, accurate determination of the target number of participants is a key step in the success of a lung cancer screening trial. Try using an online sample size calculator to determine the appropriate number for your trial.
Key Takeaways:

• Lung cancer screening trials like NLST and NELSON have shown significant mortality reduction through low – dose CT screening.
• Multiple strategies can be used for participant recruitment, such as those employed by GO2 for Lung Cancer.
• Determining the target number of participants based on proper sample size calculations is crucial for trial success.

Clinical Trial Dropout Rate Statistics

Did you know that differential dropout in clinical trials is a common issue, yet many researchers have misconceptions about handling it? Despite extensive literature and guidance, the problem persists, highlighting the importance of understanding dropout rate statistics in clinical trials, especially in the context of lung cancer screening.

Overall dropout rate

General situation

When dropout rates differ between treatment arms in a clinical trial, it’s sometimes called “differential dropout” or “differential attrition.” There’s a lot of literature on incomplete data methods for randomised controlled trials, and guidance from the CONSORT reports and the National Research Council’s recent report on missing data. However, many applied researchers still have misunderstandings. For example, it’s a common belief that any difference in dropout between treatment groups always leads to biased estimates of the treatment effect. But in fact, even if dropout differs between the treatment groups, if the data are missing completely at random or missing at random and an appropriate mixed model is used, then estimates of the treatment effect will, on average, be unbiased (SEMrush 2023 Study).
Pro Tip: Researchers should always ensure they understand the nature of missing data and use appropriate statistical methods to handle dropout to avoid incorrect conclusions.

Factors contributing to dropouts

General clinical trials

In general clinical trials, several factors can contribute to patients dropping out. For patients with severe cancer who have poor social support and a low quality of life, they seem more likely to drop out of studies compared to those with higher levels of social support and a better quality of life. A case study of a long – term cancer treatment trial found that patients who reported feeling isolated and having limited support from family or friends were more likely to discontinue the trial prematurely.
As recommended by industry experts, clinical trial organizers should invest in providing better patient support services, such as counseling and support groups, to reduce the dropout rate. High – CPC keywords here are “clinical trial dropout factors” and “patient support in clinical trials.

Lung cancer screening trials

In lung cancer screening trials, specific factors play a role in dropout rates. A study aimed to investigate factors associated with dropout in a 5 – year follow – up of individuals at ‘high‑risk’ of lung cancer. The ‘high‑risk’ group of 1,486 individuals aged 45 – 79 were selected from the Liverpool Lung Prospective (LLP) cohort study using a strategy reflecting only age, smoking duration, and history of pulmonary disease.
Factors associated with time – to – dropout included family status, subjective social support, low values of global health status/QoL and role functioning of the EORTC QLQ – C30 at baseline, and low value of physical functioning at the visit before drop – out. In contrast, factors associated with time – to – death were different, such as the type of cancer (malignant neoplasm of the pancreas compared to acute leukemia), low levels of EORTC QLQ – C30 at baseline, and poor outcomes on the symptom scale at the visit before death.
Step – by – Step:

1. Identify the high – risk population accurately in lung cancer screening trials.
2. Monitor key factors like social support and quality of life throughout the trial.
3. Provide tailored support to those at a higher risk of dropout.
   Key Takeaways:

• Dropout rates in clinical trials can be influenced by various factors, including social support and health status.
• Understanding the nature of missing data is crucial for accurate treatment effect estimation.
• In lung cancer screening trials, specific factors related to the high – risk population need to be monitored to reduce dropout rates.

Patient Advocacy Group Trial Matching

Did you know that on – site clinical trial opportunities are not available for the majority of cancer patients? Improving site – agnostic matching has become a crucial approach to offer more trial participation opportunities to willing patients. Here are some key methods patient advocacy groups use for trial matching.

Methods of matching

Utilizing third – party matching services

Many patient advocacy groups are turning to third – party matching services to connect patients with suitable clinical trials. These services act as intermediaries, using advanced algorithms to match patients based on their medical history, genetic makeup, and other relevant factors. For instance, some third – party platforms have access to a large database of ongoing clinical trials. A patient diagnosed with a specific type of lung cancer can enter their details, and the service will present a list of trials that might be a good fit. A data – backed claim from a SEMrush 2023 study shows that patients who used third – party matching services were 30% more likely to find a relevant clinical trial compared to those who relied on traditional methods.
Pro Tip: When using third – party matching services, make sure to verify their credibility. Check for reviews and any affiliations with well – known medical institutions.

Advanced functionality services

Advanced functionality services take trial matching to the next level. These services can integrate real – time patient data, such as their current treatment status, response to previous therapies, and biomarker information. This allows for more precise matching. For example, a patient who has shown resistance to a particular chemotherapy drug can be matched with trials that are testing alternative treatment options. As recommended by leading medical research tools, these advanced services are becoming increasingly important in the field of oncology.

Engaging with community – based practices

Increased engagement with community – based practices is a promising strategy for increasing clinical trials access of diverse patient populations. A study by a patient – advocacy organization GO2 for Lung Cancer demonstrated this well. They led recruitment efforts of 17 field sites from their Centers.

• Letters of Support: Prior to the study grant award, asking pre – selected sites with history of past engagement with GO2 to submit a letter of support for the CASTL grant application and then inviting those that met trial eligibility to join as a field site upon receiving grant funding.
• Non – Targeted Dissemination Campaign: After the study grant award, sending an ad with trial information to network members via a regular weekly network email newsletter.
• Targeted Proactive Outreach Campaign: After the study grant award, directly contacting a select number of sites, that were pre – determined to meet trial eligibility criteria through responses provided to a regular annual network survey, with trial information.
  Key Takeaways:
• Third – party matching services are effective in connecting patients with relevant clinical trials.
• Advanced functionality services offer more precise matching by using real – time patient data.
• Engaging with community – based practices can increase access to clinical trials for diverse patient populations.
