Video-assisted thoracic surgery (VATS) is a minimally invasive technique that has many advantages in postoperative pain and recovery time. Because of its advantages, VATS is one of the surgical techniques widely used in patients with lung cancer. Most surgeons perform VATS for lung cancer with three or more incisions. As the technique of VATS has evolved, single-port VATS for lung cancer has been attempted and its advantages have been reported. We describe our experiences of VATS for lung cancer with a single incision in this report.

Although recent advances in molecular targeted therapy and immuno-oncology have revolutionized the landscape of lung cancer therapeutics, cytotoxic chemotherapy remains an essential component of lung cancer treatment. Extensive evidence has demonstrated the clinical benefit of chemotherapy, either alone or in combination with other treatment modalities, on survival and quality of life of patients with early and advanced lung cancer. Combinational approaches with other classes of anti-neoplastic agents and new drug-delivery systems have revealed promising data and are areas of active investigation. Chemotherapy is recommended as a standard of care in patients that have progressed after tyrosine kinase inhibitors or immune checkpoint inhibitors. Chemotherapy remains the fundamental means of lung cancer management and keeps expanding its clinical implication. This review will discuss the current position and future role of chemotherapy, and specific consideration for its clinical application in the era of precision medicine.

Lung cancer is the most commonly diagnosed cancer and the leading cause of cancer-related deaths worldwide. Globally, there were an estimated 1.8 million new cases and 1.59 million deaths in 2012. In Korea, the incidence of lung cancer is increasing and 24,267 (47.6/100,000) patients with lung cancer were registered at the Korea Central Cancer Registry in 2015. Previous nationwide surveys of lung cancer were performed in 1998 by the Korean Academy of Tuberculosis and Respiratory Diseases and in 2007 by the Korean Association for Lung Cancer (KALC), but the studies faced difficulties in maintaining lung cancer registry because of limitations regarding the Private Information Protection Act. To produce unbiased and reliable epidemiological data, the KALC and Korean Central Cancer Registry developed a detailed lung cancer registry (KALC-R) data structure. Following a pilot survey of 489 lung cancer cases in 2013, about 10% of the sampled lung cancer cases from the Korean Central Cancer Registry are surveyed each year. With the analysis of detailed data from the KALC-R, an important epidemiological background for scientific research or policy development is expected to be generated.

Sarcoidosis is an inflammatory disease involving multiple-organs with an unknown cause. The new onset of sarcoidosis associated with therapeutic agents has been observed in 3 clinical settings; tumor necrosis factor antagonists in autoimmune rheumatologic diseases, interferon alpha with or without ribavirin in patients with chronic hepatitis C or melanoma, and antineoplastic agent-associated sarcoidosis in patients with hematologic malignancies. Here, we report a female patient who developed sarcoidosis after capecitabine treatment as an adjuvant chemotherapy for sigmoid colon cancer. To our knowledge, this is the first report of a capecitabine-induced sarcoidosis.

Lung cancer remains the most common cause of cancer-related deaths worldwide. Although there are many possible treatments, including targeted therapies such as epidermal growth factor receptor tyrosine kinase inhibitors and anaplastic lymphoma kinase inhibitors, new therapeutic strategies are needed to improve clinical outcomes. Immunotherapy through the use of immune checkpoint inhibitors has provided one of the most important breakthroughs in the management of solid tumors, including lung cancers, and has shown promising results in numerous clinical trials. This review will present the current status of immunotherapy for lung cancer and future perspectives on these treatments.

Accurate lymph node staging of lung cancer is crucial in determining optimal treatment plans and predicting patient outcome. Currently used lymph node maps have been reconciled to the internationally accepted International Association for the Study of Lung Cancer (IASLC) map published in the seventh edition of TNM classification system of malignant tumours. This article provides computed tomographic illustrations of the IASLC nodal map, to facilitate its application in day-to-day clinical practice in order to increase the appropriate classification in lung cancer staging.

Background: Pancreatic cancer is a highly aggressive solid tumor. Patients with metastases from pancreatic cancer have poor survival rates. Here, we report the outcomes of 6 patients for whom resection of lung metastases was performed after a pancreatectomy to treat pancreatic cancer. Methods: We retrospectively reviewed the perioperative clinical data of patients with lung metastases resulting from primary pancreatic cancer who were treated with lung resection between 2008 and 2015. We report 6 cases where lung resection was performed to treat lung metastases after a pancreatectomy. Results: The number of lung metastases was 1 in 5 cases and 2 in 1 case. The surgical procedures performed to treat the lung metastases included 4 wedge resections and 2 lobectomies. The cell type of the primary tumor and metastases was tubular adenocarcinoma in 5 cases and intraductal papillary-mucinous carcinoma in 1 case. All 6 patients survived with a mean follow-up period of 65.6 months, although the disease recurred in 2 patients. Conclusion: Resection of lung metastases resulting from primary pancreatic cancer may lengthen survival, provided the patient can tolerate surgery.

Objectives: Approximately 10% to 15% of lung cancer cases occur in never-smokers. Hormonal factors have been suggested to lead to an elevated risk of lung cancer in women. This systematic review (SR) aimed to investigate the association between hormonal replacement therapy (HRT) and the risk of lung cancer in women using cohort studies. Methods: We first obtained previous SR articles on this topic. Based on these studies we made a list of refereed, cited, and related articles using the PubMed and Scopus databases. All cohort studies that evaluated the relative risk of HRT exposure on lung cancer occurrence in women were selected. Estimate of summary effect size (sES) with 95% confidence intervals (CIs) were calculated. Results: A total of 14 cohort studies were finally selected. A random effect model was applied due to heterogeneity (I-squared, 64.3%). The sES of the 14 articles evaluating the impact of HRT exposure on lung cancer occurrence in women indicated no statistically significant increase in lung cancer risk (sES, 0.99; 95% CI, 0.90 to 1.09). Conclusions: These results showed that HRT history had no effect on the risk of lung cancer in women, even though the sES of case-control studies described in previous SR articles indicated that HRT had a protective effect against lung cancer. It is necessary to conduct a pooled analysis of cohort studies.

The pulmonary sarcomatoid carcinoma is a rare malignant tumor, which is composed of an admixture of carcinomatous and sarcomatous components, and accounts for 0.3% of all pulmonary neoplasms. Clinicopathological features are often related to anatomical location: central endobronchial type and peripheral parenchymal type. Noninvasive diagnostic test had a low yield in detection sarcomatoid carcinoma. Metastasis to the regional lymph nodes and to distant organ is common. The prognosis is poor and the median survival is about 15 months. We report two cases of pulmonary sarcomatoid carcinoma with review of literatures.

We describe herein an extremely rare case of a recurrent primary pulmonary malignant fibrous histiocytoma 3 months after operation that occurred in a 55-year-old man who was treated with chemotherapy and radiotherapy successfully. Until now, 36 months later, the patient has shown no evidence of tumor recurrence. The clinical, radiographic, and pathologic features are reported here together with a brief review of the literature.
