ObjectivesDespite a sharp increase in e-cigarette use, there is debate about whether e-cigarettes are a viable alternative for harm reduction, and the forms that regulation should take. Healthcare providers can be effective in offering guidance to patients and their families and shaping regulatory policy. We described lung cancer specialists’ attitudes toward e-cigarettes and its regulation.MethodsWe undertook a nationwide survey of pulmonologists, thoracic surgeons, medical and radiological oncologists who are members of Korean Association for Lung Cancer. Survey items included beliefs and attitudes toward e-cigarettes, attitudes toward e-cigarette regulation and preparedness on discussing e-cigarettes with their patients.ResultsMost respondents believed that e-cigarettes are not safer than conventional tobacco cigarettes (75.7%) or smokeless tobacco (83.2%), and feared that discussing e-cigarettes with the patients would encourage use (65.4%). They did not consider it a smoking cessation treatment (78.3%), and thus would not recommend it to smokers who do not want to quit (82.2%) or who failed to quit with conventional smoking cessation treatment (74.1%). Most respondents supported all examples of e-cigarette regulations, including the safety and quality check (97.8%), warning label (97.8%), advertisement ban (95.1%), restriction of flavoring (78.4%), minimum purchasing age (99.5%), and restriction of indoor use (94.6%). Most learned about e-cigarettes from media and advertisements, or conversation with patients rather than through professional scientific resources, and reported discomfort when discussing e-cigarette with patients.ConclusionLung cancer specialist physicians in Korea doubt the safety of e-cigarette and use of e-cigarette as smoking cessation treatment, and supported strict regulation. However, only 20% reported that they obtained information on e-cigarettes from the scientific literature and many lacked adequate knowledge based on scientific evidence, suggesting the need for better preparedness. Nevertheless, the views of professionals revealed from our study could help to develop clinical guidelines and regulatory guidance.

PurposeThe aim of this study was to investigate epidemiology, clinical characteristics and sex differences of patients with lung cancer using nationwide registry in Korea.Materials and MethodsThe Korean Association for Lung Cancer developed a registry in cooperation with the Korean Central Cancer Registry, and surveyed about 10% of lung cancer cases. For this first survey of cases diagnosed in 2014, cases were selected through a systematic sampling method.ResultsTotal 2,621 lung cancer patients were surveyed, and the median patient age was 70 years. During the study period, adenocarcinoma was the most frequent histologic type, the proportion of female patients was 28.4%, and women had a better prognosis (median survival, not reached vs. 13 months; p<0.001) than did men for non-small cell lung cancer. The proportion of never-smokers was 36.4%, and never-smoking was more prevalent in women than in men (87.5 vs. 16.0%, p<0.001). Epidermal growth factor receptor (EGFR) mutations were found in 36.8% of stage IV adenocarcinoma patients, and higher in female compared to male patients (51.2 vs. 26.6%, p<0.001). In addition, patients with EGFR mutation showed better survival (median survival, 18 vs. 8 months; p<0.001) than patients without EGFR mutation in these patients.ConclusionThis is the first survey to gather unbiased nationwide lung cancer statistics in Korea. More than one-third of lung cancer patients had no smoking history. Female had a high proportion of non-smoker, more adenocarcinoma with EGFR mutation and generally better prognosis than male.

Lung cancer in Korea occurs predominantly in elderly patients, with adenocarcinoma being the most frequent subtype. The prognosis was poorer in ever-smokers and older, malnourished, and untreated patients with advanced lung cancer.

VATS is a safe and effective procedure for PSP in children. However, the risk of recurrence is increased in children and it is related to the formation of new bullae.

Esophageal duplication cyst is a rare congenital esophageal anomaly of the foregut. This cyst usually occurs in isolation, and thus far, was treated by enucleation through thoracoscopic or thoracotomic surgery. Here we report a case of multiple esophageal duplication cysts that showed different pathological findings, i.e., the cysts were lined with pseudostratified ciliated columnar and stratified squamous epithelium. Esophageal cysts were incidentally detected in a 53-year-old man during the treatment of pneumonia. In chest-computed tomography, the cysts showed a thin wall and homogeneous inner density, while in endoscopy, no communication with esophageal mucosa was observed. We resected the esophageal cysts with endo-staplers under thoracoscopic surgery. No postoperative complications, including esophageal mucosal injury, occurred. A follow-up chest computed tomography revealed the complete resection of the cysts.
