PURPOSE: The purpose of this study was to evaluate protocols for low dose CT (LDCT) for lung cancer screening on a Revolution CT (GE Healthcare; Waukesha, WI). Lung cancer the leading cause of cancer death for men and women, and more deaths are attributable to lung cancer than breast, colon and prostate cancers combined. Recently, the National Lung Screening Trial (NLST) showed LDCT screening resulted in a 20% reduction in lung cancer mortality and 6.7% in mortality from all causes [NEJM, 2011]...

Lung cancer screening by low-dose chest computed tomography is currently implemented in the U.S. After implementation of screening, a stage shift may be observed from around 15% stage I non-small cell lung cancers (NSCLCs) in routine clinical practice to up to 70% in screening patients. This indicates a move in treatment options from advanced to early lung cancers, especially in those with small suspected intrapulmonary nodules. Areas covered: We have reviewed the current status of lung cancer screening from the different randomized controlled lung cancer screening studies and the clinical evidence so far for both surgical and non-surgical treatment options for (screen-detected) stage I NSCLC...

Stage I breast carcinoma is classified when an invasive breast carcinoma is ≤2 cm in diameter (T1), with no regional (axillary) lymph node metastases (N0) and no distant metastases (M0). The most common sites for metastases from breast cancer are the skeleton, lung, liver, and brain. In general, women and health care professionals prefer intensive screening and surveillance after a diagnosis of breast cancer. Screening protocols include conventional imaging such as chest radiography, bone scan, ultrasound of the liver, and MRI of brain...

Lung cancer screening with a low radiation dose chest CT scan has been shown to reduce the number of people, in a well-defined very high-risk cohort, who die from lung cancer. Many potential screening-related harms have been identified, including anxiety and morbidity related to the evaluation of screen-detected findings. A favorable balance of the benefit and harms of lung cancer screening requires careful implementation of a screening program, with a focus on several obstacles to the success of the program...

The first Chinese-German Lung Cancer Expert Panel was held in November 2015 one day after the 7th Chinese-German Lung Cancer Forum, Shanghai. The intention of the meeting was to discuss strategies for the diagnosis and treatment of lung cancer within the context of lung cancer screening. Improved risk classification criteria and novel imaging approaches for screening populations are highly required as more than half of lung cancer cases are false positive during the initial screening round if the National Lung Screening Trial (NLST) demographic criteria [≥30 pack years (PY) of cigarettes, age ≥55 years] are applied...

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) is standard of care for small lung resections at many centres. Computed tomography (CT)-guided insertion of microcoils can aid surgeons in performing VATS resections for non-palpable lung nodules deep to the lung surface. METHODS: Retrospective analysis of CT-guided microcoil insertions prior to VATS lung resection at a single institution from October 2008 to January 2014. RESULTS: A total of 63 patients were included (37% male, mean age 61...

BACKGROUND: Lung cancer screening may provide a "teachable moment" for promoting smoking cessation. This study assessed smoking cessation and relapse rates among individuals undergoing follow-up low-dose chest computed tomography (CT) in a clinical CT lung screening program and assessed the influence of initial screening results on smoking behavior. METHODS: Self-reported smoking status for individuals enrolled in a clinical CT lung screening program undergoing a follow-up CT lung screening exam between 1st February, 2014 and 31st March, 2015 was retrospectively reviewed and compared to self-reported smoking status using a standardized questionnaire at program entry...

The US National Lung Screening Trial showed that individuals randomly assigned to screening with low-dose CT scans had 20% lower lung cancer mortality than did those screened with conventional chest radiography. On the basis of a review of the literature and a modelling study, the US Preventive Services Task Force recommends annual screening for lung cancer for individuals aged 55-80 years who have a 30 pack-year smoking history and either currently smoke or quit smoking within the past 15 years. However, the balance between benefits and harms of lung cancer screening is still greatly debated...

PURPOSE: Once lung cancer is detected due to clinical symptoms or by being visible on chest X-ray, it is usually high stage and non-operable. In order to improve mortality rates in lung cancer, low-dose CT (LDCT) screening of "high risk" individuals is gaining popularity. However, the rate of malignancy in LDCT detected sub-centimetre lung nodules is not clear. We aimed to analyze surgically resected specimens in this patient group to explore cost effectiveness and recommendations for clinical management of these nodules...

CLINICAL/METHODICAL ISSUE: Attempts at the early detection of lung cancer using imaging methods began as far back as the 1950s. STANDARD RADIOLOGICAL METHODS: Several studies attempted to demonstrate a reduction of lung cancer mortality by chest radiography screening but all were unsuccessful. METHODICAL INNOVATIONS: Even the first small screening studies using computed tomography (CT) could not demonstrate a reduction in lung cancer-specific mortality until in 2011 the results of the largest randomized controlled low-dose CT screening study in the USA (NLST) were published...

With the widely application of chest computed tomography (CT) and gradual generalization of lung cancer screening project for high risk populations, more and more "tiny lung cancers" were identified. Due to the difficulty in intraoperative orientation, their less aggressiveness, and excellent short/long term prognosis, the 'tiny lung cancers' posed new challenges for the surgery in the treatment of lung cancer. In this review, theirfore, we focused on these challenges and presented the progress in lung cancer screening, orientation of lung nodules, lobectomy and sublobectomy, and lymph node dissection...
