Implantable Microdevices for in Situ Evaluation of Drug Responses in Lung Cancer

This research is being done to study the safety and feasibility of implanting and retrieving a microdevice that releases microdoses of 20 specific drugs or drug combinations as a possible tool to evaluate the effectiveness of several cancer drugs against lung cancer or mesothelioma. The name of the intervention(s) involved in this study are: Implantable Microdevice (IMD) Surgery (excision of tumor) Drugs used in this study will include drugs already used as standard of care for the treatment of lung cancer and mesothelioma, or other drugs that are approved or being investigated for these indications.

Implementation of Smoking Cessation Support During Lung Cancer Workup

The aim of the present project is to implement smoking cessation support in hospital-based lung cancer workup. The effect on 1) patients' smoking cessation attempts, motivation, quality of life and psychosocial consequences of lung cancer workup as well as 2) hospitals' number of referrals to municipality-based smoking cessation programmes will be evaluated in a pragmatic, cluster-randomised controlled setup, where participating hospitals will be assigned to the intervention arm (implementation of smoking cessation support) or the control arm (usual practice). Patients' and healthcare professionals' experiences with and barriers towards smoking cessation support will be explored in an interview-based, qualitative study.

ctDNA Mutations and Methylation Status for Early Detection of Lung Cancer in Patients With Suspicious Lung Nodules

Lung Cancer is common in Asia and is different from lung cancer from Western countries in terms of lung cancer epidemiology and management. Lung cancer can be detected early but most early-stage lung cancer appear as lung nodules with suspicious features on imaging. Workup and surveillance for subjects with suspicious lung nodule is a clinical problem. There is no consensus and clinical practice usually varies with local epidemiology of lung diseases namely the local clinical characteristics especially with lung cancer and pulmonary tuberculosis. The clinical challenge is to address whether pulmonary nodules identified on CT screening carry short- and long-term risk for lung cancer. The main objective of this study is to test the improvement of efficiency of diagnostic evaluation with clinical parameters and ctDNA mutation/methylation profiling for artificial intelligence modeling of for early detection of lung cancer in subjects with suspicious lung nodules. The hypothesis is that ctDNA mutation and methylation will enhance early detection of lung cancer in patients with suspicious lung nodules. This is a longitudinal cohort study. A total of 200 subjects (100 from Hong Kong and 100 from Vietnam) with suspicious lung nodules on CT Thorax will be recruited. Blood samples will be collected at recruitment and subsequent 6 months follow up. ctDNA mutations and methylation with SPOTMAS Lung assays would be performed at baseline and at 6 months follow-up. The CT scan where the suspicious lung nodules were identified, will be used as baseline scan for recruitment. Recruited subjects will be arranged with a non-contrast LDCT scans at 6 months follow-up. The primary outcome measure of the study is the detection of ctDNA mutation and methylation in correlation with diagnosis of lung cancer or persistence of suspicious lung nodules. The secondary outcome measures of the study are the Sensitivity and specificity of clinical biomarkers in correctly identifying malignant lung nodule, i.e., lung cancer.

Preoperative Decision-Making in Patients With Pulmonary Nodules Suspected of Lung Cancer

Patients with pulmonary nodules that are highly suspected to be lung cancer often need to make important treatment decisions before a definite pathological diagnosis is available. These decisions may include whether to undergo surgery, whether to continue follow-up, whether to have further diagnostic tests, and how to understand the potential benefits and risks of different management options. This prospective observational study aims to describe the preoperative decision-making status of adult patients with pulmonary nodules suspected of lung cancer. The study will assess patients' decision self-efficacy, decisional conflict, shared decision-making experience, and decision regret using standardized questionnaires. It will also explore factors associated with better or worse decision quality, such as demographic characteristics, clinical information, health literacy, doctor-patient communication, family involvement, and emotional status. No treatment or intervention will be assigned by the study. Participants will receive routine clinical care, and study data will be collected mainly through questionnaires before surgery or during the preoperative period. The findings may help clinicians identify patients who need additional decision support and improve communication during preoperative decision-making for suspected lung cancer.
