Feasibility Study of Nivolumab in Combination with Carboplatin Plus Paclitaxel and Concurrent Thoracic Radiation in Patients with Untreated Unresectable Locally Advanced Non-Small Cell Lung Cancer.

Despite advancements in diagnosing and treating non-small cell lung cancer (NSCLC), the prognosis remains poor. Immune checkpoint inhibitors have shown promise in enhancing survival rates. Therefore, this study aimed to investigate the safety of nivolumab administration with concurrent chemoradiation therapy (CCRT) in patients with unresectable locally advanced NSCLC.

Long-term survival with nivolumab followed by irinotecan after total gastrectomy in alpha-fetoprotein-producing gastric cancer: a case report and review of the literature.

Background: Alpha-fetoprotein-producing gastric cancer (AFPGC) is a rare type of aggressive gastric cancer (GC) with a dismal prognosis. We present a patient with AFPGC who achieved long-term survival through a multidisciplinary approach.

Case Presentation: A 67-year-old man with advanced GC was referred to our hospital for systemic chemotherapy.

Comprehensive Kinase Activity Profiling Revealed the Kinase Activity Patterns Associated with the Effects of EGFR Tyrosine Kinase Inhibitor Therapy in Advanced Non-Small-Cell Lung Cancer Patients with Sensitizing EGFR Mutations.

EGFR mutations are strong predictive markers for EGFR tyrosine kinase inhibitor (EGFR-TKI) therapy in patients with non-small-cell lung cancer (NSCLC). Although NSCLC patients with sensitizing EGFR mutations have better prognoses, some patients exhibit worse prognoses. We hypothesized that various activities of kinases could be potential predictive biomarkers for EGFR-TKI treatment among NSCLC patients with sensitizing EGFR mutations.

Disappearance of recurrent thymic epithelial tumor following corticosteroid and cyclosporine treatment: A case report.

Thymic epithelial tumors (TETs) are considered orphan neoplasms, and treatment options for recurrent or metastatic stages are limited. Here, we have reported a case of recurrent TET that showed complete remission after receiving high-dose corticosteroids followed by low-dose corticosteroids and cyclosporine. No recurrence was observed for the next 2 years.

Rapid and dramatic responses to dabrafenib and trametinib in BRAF V600E-mutated lung adenocarcinoma.

V-raf murine sarcoma viral oncogene homologue B1 (BRAF) is a proto-oncogene that regulates cell proliferation and survival. BRAF V600E-mutated lung cancer has aggressive characteristics and is resistant to chemotherapies. Combination of BRAF-specific inhibitor dabrafenib and mitogen-activated protein kinase kinase (MEK) inhibitor trametinib is the standard treatment for BRAF V600E-mutated lung cancer.

Interstitial lung disease associated with adjuvant and neoadjuvant chemotherapy in early breast cancer.

Background: Interstitial lung disease (ILD) is a rare adverse event in patients receiving adjuvant or neoadjuvant chemotherapy (NAC) for breast cancer. Few studies have reported the frequency of ILD in detail, and only small numbers of cases have been described in the literature. Given these previous findings concerning ILD, we retrospectively examined the clinicopathological characteristics of five cases of ILD who had received epirubicin and cyclophosphamide (EC) and compared their findings with non-ILD cases.

Serum immune modulators during the first cycle of anti-PD-1 antibody therapy in non-small cell lung cancer: Perforin as a biomarker.

Background: Currently used biomarkers for immunotherapy are inadequate because they are only based on tumor properties. In view of microenvironment changes by tumors, host immunity should be considered, which may result in identifying more accurate and easily detectable biomarkers for daily clinical practice. Here, we assessed serum immune-modulating factor levels for the response to anti-PD-1 antibodies during the first cycle in non-small cell lung cancer (NSCLC) patients.

False-Positive Elevation of CK-MB Levels with Chest Pain in Lung Adenocarcinoma.

The creatinine kinase (CK)-MB assay can be used for the early diagnosis of acute coronary syndrome. We describe the case of an 82-year-old male with lung adenocarcinoma who presented with chest pain. While laboratory findings showed elevated CK-MB levels, there was no cardiac injury.

Successful Desensitization with Crizotinib after Crizotinib-induced Liver Injury in ROS1-rearranged Lung Adenocarcinoma.

Crizotinib has been approved for patients with advanced lung adenocarcinoma harboring rearrangements of the c-ROS-1 (ROS1) and anaplastic lymphoma kinase (ALK) genes. We report a patient with ROS1-rearranged lung adenocarcinoma who developed a crizotinib-induced mixed/cholestatic type of liver injury. The patient discontinued crizotinib after 34 days due to liver toxicity.

A systematic review of observational studies of trifluridine/tipiracil (TAS-102) for metastatic colorectal cancer.

The treatment options for patients with therapy refractory metastatic colorectal cancer (mCRC) are sparse. TAS-102 (FTD/TPI) is a new oral anti-tumour agent composed of a nucleoside analogue, trifluridine, and a thymidine phosphorylase inhibitor, tipiracil, indicated for patients with mCRC who are refractory to standard therapies. This study summarizes published and unpublished experience with FTD/TPI in clinical practice settings.

Porous diaphragm syndrome with recurrent thymoma.

Porous diaphragm syndrome describes a defect in the diaphragm in which substances pass from the peritoneal cavity to the pleural space. Defects may be congenital or acquired. Acquired defects are caused by the thinning and eventual splitting of collagen fibres in the tendinous part of the diaphragm.

Breast metastasis from EGFR-mutated lung adenocarcinoma: A case report and review of the literature.

Although lung cancer rarely metastasizes to the breast, we report a case of breast metastasis from lung adenocarcinoma harboring an epidermal growth factor receptor mutation. This breast metastasis was initially considered recurrent breast cancer and was later diagnosed based on histopathological and molecular examinations as metastasis from lung cancer.

Use of hormone therapies in disseminated carcinomatosis of the bone marrow associated with hormone receptor-positive breast cancer.

Disseminated carcinomatosis of the bone marrow (DCBM) is diffusely invasive bone metastasis resulting from solid tumors. DCBM is often associated with disseminated intravascular coagulation (DIC) or hemolytic anemia. Generally, DCBM treatment includes cytotoxic chemotherapy for underlying solid tumors and management of hematological conditions if present.

Myasthenia gravis induced by nivolumab in patients with non-small-cell lung cancer: a case report and literature review.

A 76-year-old woman who was diagnosed with non-small-cell lung cancer presented with left eyelid ptosis and grade 4 creatine phosphokinase elevation after the second cycle of nivolumab monotherapy. Nivolumab has demonstrated promising efficacy in patients with non-small-cell lung cancer in several trials. Dyspnea and muscle weakness developed rapidly with an acute exacerbation.

Pain Management of Malignant Psoas Syndrome Under Epidural Analgesia During Palliative Radiotherapy.

Malignant psoas syndrome is a rare malignant condition presenting as lumbosacral plexopathy and painful fixed flexion of the hip. Metastasis to the psoas muscle is observed, which damages the nerve bundles in the lumbosacral plexuses. The syndrome presents as refractory lower back pain with several other neurological symptoms.

Drug-induced Pneumonitis Following the Administration of TAS-102.

A 59-year-old woman, diagnosed with advanced rectal cancer, presented with a low-grade fever and dyspnea on exertion after the 2nd cycle of TAS-102. TAS-102 has promising efficacy in patients with metastatic colorectal cancer. A CT scan revealed mosaic patterns with bilateral ground-glass opacities.

Spontaneous pneumothorax due to bronchopleural fistula following reirradiation for locoregionally recurrent squamous cell lung cancer.

Spontaneous pneumothorax following radiotherapy for pulmonary malignancy is an unusual clinical condition. Here, we report a case of a 78-year-old male suffering from dyspnea during radiotherapy for squamous cell lung cancer of the right main bronchus. Imaging studies and fiberoptic bronchoscopy revealed that pneumothorax was due to a bronchopleural fistula.

TP53 mutations, tetraploidy and homologous recombination repair defects in early stage high-grade serous ovarian cancer.

To determine early somatic changes in high-grade serous ovarian cancer (HGSOC), we performed whole genome sequencing on a rare collection of 16 low stage HGSOCs. The majority showed extensive structural alterations (one had an ultramutated profile), exhibited high levels of p53 immunoreactivity, and harboured a TP53 mutation, deletion or inactivation. BRCA1 and BRCA2 mutations were observed in two tumors, with nine showing evidence of a homologous recombination (HR) defect.

Network-based survival analysis reveals subnetwork signatures for predicting outcomes of ovarian cancer treatment.

Cox regression is commonly used to predict the outcome by the time to an event of interest and in addition, identify relevant features for survival analysis in cancer genomics. Due to the high-dimensionality of high-throughput genomic data, existing Cox models trained on any particular dataset usually generalize poorly to other independent datasets. In this paper, we propose a network-based Cox regression model called Net-Cox and applied Net-Cox for a large-scale survival analysis across multiple ovarian cancer datasets.

Highly parallel genome-wide expression analysis of single mammalian cells.

Background: We have developed a high-throughput amplification method for generating robust gene expression profiles using single cell or low RNA inputs.

Methodology/principal Findings: The method uses tagged priming and template-switching, resulting in the incorporation of universal PCR priming sites at both ends of the synthesized cDNA for global PCR amplification. Coupled with a whole-genome gene expression microarray platform, we routinely obtain expression correlation values of R(2)~0.

Expression and functional significance of HtrA1 loss in endometrial cancer.

Purpose: The purpose of this study was to determine if loss of serine protease HtrA1 in endometrial cancer will promote the invasive potential of EC cell lines.

Experimental Design: Western blot analysis and immunohistochemistry methods were used to determine HtrA1 expression in EC cell lines and primary tumors, respectively. Migration, invasion assays and in vivo xenograft experiment were performed to compare the extent of metastasis between HtrA1 expressing and HtrA1 knocked down clones.

Minichromosome maintenance protein 7 as a potential prognostic factor for progression-free survival in high-grade serous carcinomas of the ovary.

Minichromosome maintenance protein 7 (MCM7) is involved in replicative licensing and synthesis of DNA. It was previously identified as an overexpressed gene in high-grade serous carcinomas compared with serous borderline tumors of the ovary in cDNA microarray studies. In this study, we sought to validate MCM7 expression in 342 ovarian tumors on tissue microarrays.
