BACKGROUND: Currently, evidence-based guidelines for salvage therapy to treat mediastinal lymph node (LN) oligo-recurrence in post-resection non-small cell lung cancer (NSCLC) are limited. In patients previously treated by surgery without irradiation, radiotherapy (RT) might be safely utilized. We evaluate the clinical outcomes of salvage RT for patients with LN oligo-recurrence that developed after radical surgery for NSCLC. METHODS: Thirty-one patients with stage I-IIIA NSCLC who developed regional LN oligo-recurrence between 2008 and 2013 were reviewed...

Esophageal cancer (EC) is a common malignant tumor of the gastrointestinal tract with a high incidence in China. Zinc (Zn) deficiency is a key risk factor for the occurrence and development of EC and affects progression by regulating microRNA (miRNA, miR) expression. In addition, the dysregulation of miRNAs is accompanied by the dysregulation of their target genes in EC. In this paper, we review the potential molecular mechanisms between Zn deficiency and EC with the aim of providing new strategies and methods for early diagnosis, targeted therapy, and prognostic evaluation...

A 57-year-old man was admitted to our department 10 years ago, diagnosed with tracheal adenoid cystic carcinoma. After discontinuing chemotherapy and radiotherapy, the disease recurred in December 2016. Apatinib mesylate (500 mg/day) was administered and computed tomography revealed that his symptoms were significantly relieved. Treatment with apatinib mesylate represents a novel method of treatment for tracheal adenoid cystic carcinoma.

Pleomorphic carcinoma (PC) of the lung is a rare type of non-small cell lung cancer, exhibiting aggressive behavior and resistance to chemotherapy and radiotherapy. A previous study reported that PCs expressed high levels of PD-L1, suggesting the potential efficacy of immune checkpoint inhibitors in these tumors. We retrospectively reviewed the clinical records of three patients with PC of the lung treated with nivolumab: a 59-year-old woman (Case 1), a 66-year-old man (Case 2), and an 83-year-old man (Case 3)...

We report a case of papillary carcinoma in a mediastinal ectopic thyroid diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). In this case, the tumor was adjacent to the central airway; therefore, we attempted to perform EBUS-TBNA to obtain specimens for a diagnosis of papillary thyroid carcinoma. Surgical resection was conducted, and histological evaluation of the resected specimen confirmed ectopic papillary thyroid carcinoma, consistent with the histology from the EBUS-TBNA specimen...

Malignant peripheral nerve sheath tumor (MPNST) in the thorax is an extremely rare disease, and half of all cases of MPNST are associated with neurofibromatosis type I. Sporadic intrathoracic MPNST is difficult to diagnose and treat. Because of the rarity of intrathoracic MPNST, the optimal method of diagnosis and the efficacy of chemotherapy are unknown. Herein, we present a case of inoperable mediastinal MPNST, in which the diagnosis was immunohistochemically made by the loss of H3K27me3 expression in a transbronchial needle biopsy specimen...

BACKGROUND: Treatments that prevent the motility of breast cancer cells and inhibit formation of new capillary vessels are urgently needed. FSTL1 is a secreted protein that has been implicated in maintaining the normal physiological function of the cardiovascular system, in addition to a variety of other biological functions. We investigated the role of FSTL1 in the proliferation and migration of breast cancer and vascular endothelial cells. METHODS: Human umbilical vein endothelial cells and human breast cancer BT-549 cells were used to test the effects of FSTL1 and the N-terminal domain of FSTL1...

Invasive mucinous adenocarcinoma (IMA) is an uncommon entity in the lung, with a poor prognosis. Multifocal IMA of the lung is even more unusual, and there is little experience with effective treatments. Herein, we present a case of multifocal IMA diagnosed in a 36 year-old man by video-assisted thoracoscopic surgery. A right middle lobe and a nodule in the right upper lobe were resected, as were mediastinal lymph nodes, leaving behind an autonomous right lower lobe nodule. To explore the feasibility of molecular treatment, next-generation sequencing of genetic mutations was performed after four cycles of chemotherapy (pemetrexed + cisplatin)...

Infusion reaction is an adverse event of therapeutic monoclonal antibodies. Nivolumab, an anti-programmed death-1 antibody, directly activates T cells, which could probably interact with endothelial cells. The etiology of infusion reaction induced by nivolumab may differ from that of other antibodies; however, the detailed clinical features are unknown. We report a case of lung cancer treated with nivolumab, in which the infusion reaction manifested as plantar erythema, followed by a transient local pulmonary infiltrate around the tumor...

ROS1 rearrangement occurs in 1-2% of non-small cell lung cancer (NSCLC) cases. These patients would benefit from treatment with the anaplastic lymphoma kinase inhibitor, crizotinib; however, resistance to crizotinib inevitably develops in such patients despite an initial response. The mechanism of acquired resistance to crizotinib in patients with NSCLC with ROS1 rearrangement has not yet been identified. Herein, we report a case of a 66-year-old woman diagnosed with adenocarcinoma. PCR revealed no EGFR or ALK mutations...

BACKGROUND: MicroRNAs are often abnormally expressed in human non-small cell lung cancer (NSCLC) and are thought to play a critical role in the emergence or maintenance of NSCLC by binding to its target messenger RNA. We assessed the effects of miR-155 on cell proliferation and invasion to elucidate the role played by miR-155/PDCD4 in NSCLC. METHODS: Quantitative reverse transcription-PCR, Western blotting, and cell counting kit-8, luciferase, and transwell invasion assays were conducted on a normal human bronchial epithelial cell line (BEAS-2B) and three NSCLC cell lines (SPC-A-1, A549, and H2170)...
