Background: Lung cancer is the leading cause of cancer deaths worldwide. Although lung cancer can metastasize to various organs such as the liver, lymph nodes, adrenal gland, bone, and brain, metastases to the digestive organs, especially the colon, are rare.
Case Summary: An 83-year-old man diagnosed with lung cancer received radiation and chemoimmunotherapy, resulting in a complete clinical response.
Purpose: In Japan, both a 23-valent pneumococcal polysaccharide vaccine (PPSV23) and a 13-valent pneumococcal conjugate vaccine (PCV13) are available. Although randomized controlled trials have examined the effects of pneumococcal vaccines, few epidemiological studies have investigated the onset of pneumococcal pneumonia in general practice. In Izumo, Shimane Prefecture, Japan, a public subsidy for PPSV23 inoculation began in November 2012.

Using ECS, we aimed to evaluate whether sufficient samples for diagnosis can be obtained during bronchoscopy. We also investigated whether ECS can enable two-class diagnosis of malignant or non-malignant transbronchial biopsy specimens in real-time during bronchoscopy.

We evaluated 19 biopsy specimens based on the density of nuclei and irregularity in the nuclei shape using ECS and compared them with the histopathological findings. All 10 specimens considered malignant based on ECS were diagnosed as malignant based on histopathology.

We previously reported that the homozygous COX-2 -1195A genotype is associated with an increased risk for chronic obstructive pulmonary disease (COPD) in Japanese individuals. COPD is a significant risk factor for lung cancer due to genetic susceptibility to cigarette smoke.

Background : Although platinum-combination chemotherapy is widely used to treat advanced non-small cell lung cancer (NSCLC), not all elderly patients benefit from this regimen. In this retrospective study, we aimed to evaluate whether the Glasgow Prognostic Score (GPS), an indicator of systemic inflammation and malnutrition, could predict the tolerability and efficacy of platinum-combination chemotherapy among elderly patients with NSCLC. Methods : The eligibility criteria included patients aged ≥ 70 years with NSCLC treated with first-line platinum-combination chemotherapy at Shimane University Hospital between January 2015 and December 2018.

Aim: Gefitinib and erlotinib are efficacious and safe for older patients with epidermal growth factor receptor-mutant non-small cell lung cancer. However, prolonged use of epidermal growth factor receptor-tyrosine kinase inhibitors in older patients is difficult, owing to potential adverse events. Hence, dose reduction or treatment discontinuation is often required.

We aimed to validate the International Primary Care Airways Group (IPAG) questionnaire and to propose a novel COPD screening questionnaire based on the CT screening data of Japanese participants.
Patients And Methods: Low-dose CT screening was performed for early detection of lung cancer and COPD since 2009 in Shimane, Japan, and clinical information was collected using an original questionnaire that included all the IPAG questionnaire items and eight additional items (for eg, on dyspnea) during CT screening.
Background/aim: To predict the efficacy of platinum-containing chemotherapy, ERCC1 expression levels were investigated. Studies have shown changes in the performance of anti-ERCC1 antibodies; therefore, predicting chemotherapy efficacy by immunohistochemical assessment of ERCC1 is controversial.
Patients And Methods: Twenty-eight patients who received platinum-containing chemotherapy and underwent computed tomography evaluation 6-9 weeks after therapy initiation were retrospectively identified.
Background: In Japan, the Ministry of Health, Labour and Welfare population dynamics investigation showed a decrease in the number of deaths related to asthma in recent years. In 2016, the mortality rate was 1.2 deaths per 100,000 population.

Thus, we retrospectively investigated the difference in attitudes toward palliative care referral between medical oncologists and pulmonologists in Japan. Methods We retrospectively reviewed the charts of patients with thoracic malignancy who died at Shimane University Hospital between June 2011 and October 2015.

Methods: This was a retrospective review of 34 lung adenocarcinoma patients with multiple synchronous GGNs in an Asian population.
Background: Since the computed tomography (CT) findings of nontuberculous mycobacterial lung disease are similar to those of pulmonary tuberculosis (PTB), we often have difficulty differentiating the two. In this study, we compared the differences in chest CT findings and their locations between cases of PTB and Mycobacterium avium complex lung disease (MACLD).
Methods: The subjects were 100 MACLD patients and 42 PTB patients treated at our hospital from May 2005 to August 2015.
Pulmonary nodular lymphoid hyperplasia (PNLH) involves proliferative lymphatic tissues and is reportedly associated with inflammatory disease or autoimmune disorders. Herein, we describe a case of PNLH with difficult diagnosis because of antibiotics therapy-induced reduction in the abnormal tumour shadow. An 86-year-old man was admitted for persistent cough and bloody sputum.

Assessment of performance status, cognitive function and social background is necessary for the treatment of older patients. The aims of the present study were: (i) to establish an evaluation system using electronic medical records; and (ii) to distinguish older patients as fit versus vulnerable or frail according to a geriatric assessment (GA) system score.
