Adenocarcinoma Of Lung

Pulmonary ground-glass nodules (GGNs) are commonly found on chest CT scans. Some stay stable for years, while others slowly or rapidly turn into lung cancer. Doctors currently follow these nodules with repeated CT scans, but it is difficult to tell ahead of time which nodules will progress, how fast they will progress, and which ones can be safely monitored rather than immediately treated. This observational study aims to develop and validate an artificial intelligence (AI) model that uses each patient's series of CT scans over time to predict the long-term growth behavior of a GGN. The research team will collect three retrospective single-center cohorts from Peking University People's Hospital (a development cohort and two internal test cohorts, one from surgically resected patients and one from non-operated patients followed by serial CT) as well as a prospective multi-center validation cohort enrolled after the AI model is locked. For every patient, each GGN is automatically segmented in three dimensions on every CT scan. A deep learning model extracts imaging features at each timepoint and feeds the sequence of features, together with the actual times between scans, into a time-aware sequence model. The model is trained to predict (i) whether the nodule will show radiological progression at 1, 3, and 5 years after baseline, and (ii) which of four long-term growth patterns the nodule will follow: stable, slow progression, slow-then-rapid progression, or rapid progression. In patients who were ultimately resected, the histopathological diagnosis serves as a secondary reference standard. This is an observational study. No experimental treatment is given. All CT scans and clinical visits are part of routine clinical care.

The goal of this clinical trial is to determine clinical advantages for LP-300 in combination with carboplatin and pemetrexed in the never smoker patient population. The primary objectives of this study are to determine progression-free survival (PFS) and overall survival (OS) in the study-defined patient population when LP-300 is co-administered with the standard of care chemotherapy drugs carboplatin and pemetrexed compared to carboplatin and pemetrexed alone. This has been designed as a multicenter, open label, phase II trial with 90 patients to be enrolled in the United States.

This study is an observational study of blood and tissue biomarkers. Investigators plan to evaluate the accuracy of lung cancer biomarkers found in the blood in determining if a lung nodule is cancer or benign. Investigators also plan to examine another biomarker found in the tumor tissue to identify participants after lung cancer surgery who have a high risk for recurrent cancer. Finally, investigators plan to determine if one of the blood-based biomarkers can be used to detect any late cancer recurrence.

This is a randomized, active-controlled, parallel-group, double-blind Phase II trial, of oral restorative microbiota therapy (RMT) or placebo combined with intravenous (IV) durvalumab (MEDI4736) plus chemotherapy in patients with treatment naïve advanced or metastatic adenocarcinoma non-small cell lung cancer (NSCLC)

The assessment of surgical and postoperative risks in thoracic surgery is a field of significant interest because the surgical procedure causes substantial changes in the body's homeostasis. The postoperative course is characterized by considerable clinical variability compared to the preoperative classification, which highlights more homogeneous data among various patient groups. This variability appears to result from individual differences in response to extensive pulmonary resections. Notably, the homogeneity of preoperative data does not correlate with the greater variability observed in the postoperative course. The application of algorithms derived from BIVA in bioimpedance studies has proven particularly useful for prognostic assessments in oncology, as it can evaluate a patient's hydration status and muscle reserves at the time of diagnosis or the start of clinical/surgical treatment. Understanding body composition, particularly the quantity and/or quality of muscle mass, is essential for diagnosing sarcopenia. By passing a low-intensity alternating current (imperceptible to the patient) through the body, BIVA measures provide insights into body water distribution (both intracellular and extracellular), lean mass and skeletal muscle mass. Overall, the test offers a detailed picture of hydration status and skeletal muscle composition. Another validated tool for assessing sarcopenia, which provides information on both muscle quantity (via cross-sectional area measurements) and muscle quality (via muscle density measurements), is computed tomography (CT). CT imaging is typically performed for diagnostic and staging purposes before surgery in thoracic surgery patients, either alone or in combination with positron emission tomography (PET). Our study will focus on assessing correlations between clinical, imaging, and bioimpedance data and postoperative outcomes, with particular attention to the incidence of atrial fibrillation (AF), pulmonary atelectasis requiring treatment, and increased pleural drainage production. Additionally, we will evaluate the relationship between the surgical approach (open surgery vs. video-assisted thoracoscopic surgery, or VATS) and short-term bioimpedance values.

The core purpose of this study is to investigate whether the extracellular volume (ECV) fraction measured in delay phase by dual energy computed tomography (DECT) can distinguish precancerous lesions from early-stage lung adenocarcinomas, which could assist clinical decision making for surgery operation indication and strategy.

APOLLO 11 main aim is to build a strong Italian long-lasting lung cancer network (in around 48 Italian centres) on real world data and translational research by creating a decentralized long-term national database (settle locally in each centre) and a "virtual" multilevel biobank in each centre. Besides, APOLLO 11 will take advantage of the translational research joint effort with the credo "unity is strength".
