RESUMO
PURPOSE: Although cancer cachexia is mainly characterized by persistent loss of body weight (BW), usually in response to a malignancy, the pathophysiology of cachexia remains unresolved. To elucidate the relationship between the loss of BW and other related clinical factors, we conducted a nationwide, multi-institutional, prospective, observational study in patients with advanced non-small cell lung cancer (NSCLC). METHODS: Treatment-naïve stage IV NSCLC patients with an Eastern Cooperative Oncology Group performance status (PS) of 0-2 were eligible. BW, handgrip strength (HGS), quality of life (QOL), Karnofsky Performance Scale (KPS), biochemical parameters, and survival were evaluated at baseline and every 4 weeks for 1 year. The relationship between BW loss and other factors was examined by linear regression analysis. Estimated survival curves were drawn by the Kaplan-Meier method and applied by the log-rank test. Clinical factors associated with cancer cachexia were identified through principal component analysis. The generalized estimating equation approach was used to analyze the deterioration of QOL resulting from the progression of cachexia. RESULTS: A total of 406 patients were analyzed. BW loss was significantly associated with worsening of QOL, HGS, KPS, and biochemical parameters. The incidence of BW loss was observed throughout the study period. Overall survival was significantly shorter in patients as BW loss progressed. BW loss, decrease in HGS, anorexia, and fatigue were identified as core factors of cachexia that contributed to the deterioration of QOL. CONCLUSION: BW loss most likely deteriorated QOL and shortened survival in patients with advanced NSCLC and should be closely monitored.

A 43-year-old diabetic man had a productive cough and high fever and was admitted to another hospital. His condition did not improve despite treatment with Cefepime, and he was transferred to our hospital. Chest X-ray films and CT findings showed pulmonary infiltration and diffuse ground-glass opacities in bilateral lung fields, but disseminated nodules were not identified. Since his bronchial lavage fluid (BALF) was bloody, we suspected diffuse alveolar hemorrhage due to vasculitis. Steroid pulse therapy was given, and his fever and chest X-ray findings completely improved. However, 1 week later, he again suffered a high fever and bloody sputum, and a chest X-ray film showed granular shadows in bilateral lung fields. He died of respiratory failure on the 18th hospital day despite treatment and mechanical ventilation. An autopsy revealed many necrotizing epithelioid granulomas in both lungs, the liver, the spleen, both kidneys and both adrenal glands. These findings indicated miliary tuberculosis, and a culture of his sputum and BALF finally revealed mycobacterium tuberculosis. Marked alveolar hemorrhage and a hyaline membrane were also found in both lungs, but vasculitis was not recognized in any organ. We report this case, because to the best of our knowledge diffuse alveolar hemorrhage has not been reported as the primary symptom of miliary tuberculosis.

Klippel-Trenaunay-Weber syndrome (KTWS) is a rare congenital disorder characterized by varicose veins, cutaneous hemangiomas, hypertrophy of soft tissue and bone and arteriovenous malformations. We present a case of a 43-year-old man with KTWS. He experienced progressive pulmonary hypertension due to recurrent pulmonary embolism, which developed despite adequate anticoagulation. This case report suggests that patients with KTWS need more aggressive management and treatment of their thromboembolitic state and pulmonary hypertension.

Objective Pembrolizumab has beneï¬ted patients with advanced non-small-cell lung cancer (NSCLC) with a programmed death-ligand (PD-L) 1 high expression, but little information is available regarding its safety for patients with interstitial lung disease (ILD). The aim of this study was to assess the efficacy and tolerability of pembrolizumab for patients with advanced NSCLC and preexisting ILD. Methods We retrospectively reviewed the medical records of five patients with advanced NSCLC and preexisting ILD who received pembrolizumab monotherapy in a first-line setting. Patients All patients had mild ILD and pulmonary emphysema with a forced vital capacity within the normal range. Pembrolizumab was administered at a dose of 200 mg/body on day 1 every 3 weeks. Results The overall response rate was 60%. Four patients developed pembrolizumab-induced lung injury, which was improved in all cases by corticosteroid therapy. One patient received pembrolizumab for two years, did not experience lung injury and achieved a complete response. Conclusion Pembrolizumab has a high risk of inducing lung injury in patients with preexisting ILD, although it may be very effective in NSCLC patients with a high PD-L1 expression, even concurrent with preexisting ILD. Further large-scale studies are needed to determine risk factors of pembrolizumab-induced lung injury in such patients.

BACKGROUND/AIM: Pemetrexed plus platinum followed by pemetrexed maintenance has been one of the standard first-line treatments in advanced nonsquamous non-small cell lung cancer (NSCLC), but little is known regarding its safety and efficacy for patients with interstitial lung disease (ILD). PATIENTS AND METHODS: The medical records of 24 patients with advanced nonsquamous NSCLC and preexisting ILD who received pemetrexed and platinum doublet therapy with and without pemetrexed maintenance in the first-line setting between December 2009 and June 2016, were retrospectively reviewed. RESULTS: The median progression-free survival time was 4.7 months, and the median overall survival time was 9.5 months. Of the 24 patients analyzed, six received pemetrexed maintenance. Acute exacerbation of ILD (AE-ILD) occurred in five (20.8 %) of 24 patients, including two fatal cases. CONCLUSION: The treatment with pemetrexed plus platinum has a high risk of AE-ILD in patients with advanced nonsquamous NSCLC and preexisting ILD.

The safety of treatment with immune-checkpoint inhibitors prior to thoracic surgery in patients with non-small cell lung cancer (NSCLC) remains unclear. Here, we describe the case of a 62-year-old woman with NSCLC with programmed death ligand 1 expression on 85% of tumor cells. The patient was initially considered to have unresectable stage IIIB disease and received pembrolizumab monotherapy. After 12 cycles of pembrolizumab, the primary tumor was reduced, but a small lung nodule in another lobe was unchanged. Based on the course of image findings, the nodule was considered to be an old inflammatory change. The clinical stage was changed to stage IB and partial resection was performed. Three days after thoracic surgery, the patient began to complain of coughing and shortness of breath. A CT of the chest revealed ground-glass opacity in the bilateral lung fields, suggesting interstitial lung disease (ILD) associated with pembrolizumab. Corticosteroid therapy was started and a chest X-ray showed a reduction in the opacity with improved oxygenation. This is the first case of immune-checkpoint inhibitor-related ILD triggered by thoracic surgery following long-term immune-checkpoint therapy.

A 64-year-old woman complaining of progressive dyspnea was admitted with recurrence of massive pericardial effusion. The patient had been diagnosed with radiation pericarditis based on a previous case of pericardiocentesis. To make a diagnosis and improve her symptoms, imaging examinations and pericardial fenestration were performed. Because of difficulty making a diagnosis, after some months, pericardiotomy and incision of the epicardium were performed. The patient was ultimately diagnosed with primary malignant pericardial mesothelioma of the epithelioid type. Primary malignant pericardial mesothelioma is a rare tumor that is difficult to diagnose. An antemortem diagnosis can be made by a multidisciplinary evaluation.

Objective Although lung squamous cell carcinoma (SCC) accounts for 20-30% of lung cancer cases, new treatment options are limited. The CA031 study showed that nanoparticle albumin-bound-paclitaxel (nab-PTX) plus carboplatin produced a significantly higher overall response rate (41%) than solvent-based paclitaxel plus carboplatin in patients with lung SCC. However, the safety and efficacy of combination chemotherapy of nab-PTX and carboplatin has not yet been established for patients with concurrent lung SCC and idiopathic interstitial pneumonias (IIPs). The aim of this study was to assess the safety and efficacy profiles of nab-PTX and carboplatin in patients with lung SCC and concurrent IIPs. Methods Eight patients with inoperable-stage lung SCC and IIPs were treated with nab-PTX plus carboplatin in a first-line setting between June 2013 and December 2016. One of the eight was a woman, and the median age was 77 (range=72-80) years. Their clinical outcomes, including chemotherapy-associated acute exacerbation of IIPs, were retrospectively investigated. Results The overall response rate was 50%, the median progression-free survival time was 5.6 months, and the median overall survival time was 8.1 months. No patients experienced chemotherapy-related exacerbation of IIPs in the first-line treatment with nab-PTX plus carboplatin. However, IIPs worsened in two of four patients who received second-line chemotherapy. Conclusion Combination chemotherapy of nab-PTX and carboplatin may be an effective and safe treatment option for patients with inoperable lung SCC with IIPs. To confirm this, a large-scale prospective study is needed.

An 86-year-old Japanese man was diagnosed with stage IV lung adenocarcinoma. The patient was treated with crizotinib after echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) rearrangement was detected from his pleural effusion. He subsequently developed abdominal pain and rebound tenderness in the right lower abdomen. Contrast-enhanced abdominal CT showed a low-density area in the abdominal cavity. The size of the abscess was decreased by drainage and the administration of antibiotics. Fistulography revealed a fistula from the rectum to the abscess, and a diagnosis of lower intestinal tract perforation with abscess formation was made. Crizotinib was discontinued and treatment with alectinib was initiated. The patient remains under treatment as an outpatient at our department without adverse effects.

We present a case of metastatic recurrence of carcinoid tumor accompanied by carcinoid syndrome in a 68-year-old Japanese man, 12 years after resection of typical pulmonary carcinoid. Histopathologic examination from percutaneous liver biopsy revealed metastatic typical carcinoid. Clinical symptoms gradually improved after administration of octreotide LAR. Two years after starting treatment, the disease remains well controlled. This case report illustrates the possibility of antiproliferative effects of octreotide LAR on typical pulmonary carcinoid.
RESUMO
A 19-year-old woman admitted for hemoptysis had remarkable hypoxemia. Pulmonary artery angiography indicated diffuse telangiecatic arteriovenous malformations in the left upper lobe and part of the left lower lobe. The shunt ratio was calculated as 48.7%. Many patients of this diffuse telangiecatic type have a poor outcome, because of its seriousness, difficulty to treat and high risk of complications. In this patient, it was judged that embolization was impossible due to the form of the lesions. We performed resection of left upper lobe and a part of left lower lobe. After the operation, hypoxemia improved remarkably, as well as the shunt ratio (28.8%). No clinical sign of recurrence has been observed two years after the operation.

BACKGROUND: Maintenance therapy with full-dose erlotinib for patients with advanced non-small cell lung cancer (NSCLC) has demonstrated a significant overall survival (OS) benefit. However, 150 mg/day of erlotinib seems too toxic as maintenance therapy. This study aimed to evaluate the efficacy and safety of low-dose erlotinib (25 mg/day) as maintenance treatment after platinum doublet chemotherapy in NSCLC harboring epidermal growth factor receptor (EGFR) mutation. METHODS: Activated EGFR-mutation-positive NSCLC patients who did not progress after first-line platinum-doublet chemotherapy, ≥20 and ≤85 years old, with performance status (PS) 0-3 were included in this study. Low-dose erlotinib (25 mg/day) was administered until disease progression. The primary endpoint was overall response rate (ORR). Secondary endpoints included progression-free survival (PFS), OS, and safety. The required sample size was 40 patients. RESULTS: The study was stopped early, after achieving only 28% of planned enrollment, due to poor accrual. Between April 2011 and May 2014, 11 patients (male/female, 5/6; median age, 72 years; PS 0/1, 8/3; stage IV/relapse after surgery, 9/2; exon 19 deletions/L858R, 7/4) were enrolled and accessible in this study. Partial response (PR) was observed in 6 patients (56%). Median PFS was 14.9 months [95% confidence interval (CI), 2.7-27.1 months] and median OS was not calculable. Toxicities were generally mild. Only one patient developed grade 3 aspartate aminotransferase (AST)/alanine aminotransferase (ALT) elevation. Eight patients developed grade 1 skin rash. No treatment-related deaths were observed. Eight patients progressed, and recurrences included brain metastases (n=3), local recurrence (n=2), local recurrence plus brain metastasis (n=1), bone metastasis (n=1), and pulmonary metastasis (n=1). CONCLUSIONS: The study was stopped early due to poor accrual. However, our study suggests that maintenance therapy with low-dose erlotinib might be useful and tolerable in selected NSCLC patients harboring EGFR mutation.

We report three dengue fever cases, infected during a group tour to the Philippines. A 58-year old male experienced sudden onset of high fever 5 days after returning to Japan, followed by rash and thrombocytopenia. The other 2 cases experienced similar symptoms. Clinically suspected from the travel history, incubation time and the state of dengue fever epidemic in the Philippines, dengue virus infection was confirmed by the laboratory tests. The incidence and geographical distribution of dengue virus infection have greatly increased in recent years. There have been reports of Japanese travelers who visited dengue endemic countries, infected and developed symptoms after returning home. Dengue virus infection should be included in the differential diagnosis of the patients who develop high fever and rash after returning from tropical areas.

An 80-year-old female with non-resectable pulmonary adenocarcinoma was treated with five courses of chemotherapy consisting of gemcitabine (GEM) 1,000 mg/m2 plus vinorelbine (VNR) 25 mg/m2 (days 1 and 8, every 4 weeks). A partial response (PR) was achieved, and her complaints abated and quality of life (QOL) improved. Although gastro-intestinal symptoms and bone marrow suppression were observed as side effects, they were within a tolerable range and did not interfere with the therapy. Anti-cancer chemotherapy for non-resectable lung cancer might be worth consideration even for elderly patients more than 80 years of age.
