Lung cancer is the cardinal cause of cancer-related deaths with restricted recourse of therapy throughout the world. Clinical success of therapies is not very promising due to - late diagnosis, limited therapeutic tools, relapse and the development of drug resistance. Recently, small ∼20-24 nucleotides molecules called microRNAs (miRNAs) have come into the limelight as they play outstanding role in the process of tumorigenesis by regulating cell cycle, metastasis, angiogenesis, metabolism and apoptosis. miRNAs essentially regulate gene expression via post-transcriptional regulation of mRNA...

This study sought to evaluate the impact of prophylactic cranial irradiation (PCI) on the pattern of brain recurrence after radical treatment in patients with limited-disease small-cell lung cancer (LD-SCLC). Patients treated with radiotherapy and chemotherapy between January 2006 and December 2014 at a single institution were retrospectively examined. Radiotherapy was performed using accelerated hyperfractionated radiotherapy (twice daily, 45 Gy in 30 fractions) or conventional fractionated radiotherapy (once daily, 50 Gy in 25 fractions)...

PURPOSE: Tumor hypoxia correlates with treatment failure in patients undergoing conventional radiation therapy. However, no published studies have investigated tumor hypoxia in patients undergoing stereotactic body radiation therapy (SBRT). We aimed to noninvasively quantify the tumor hypoxic volume (HV) in non-small cell lung cancer (NSCLC) tumors to elucidate the potential role of tumor vascular response and reoxygenation at high single doses. METHODS AND MATERIALS: Six SBRT-eligible patients with NSCLC tumors >1 cm were prospectively enrolled in an institutional review board-approved study...

Pleurectomy/decortication (P/D) is the surgical treatment of choice for early malignant mesothelioma, but it remains unclear whether radiotherapy along with P/D should be used as multimodal treatment for this disease. We herein present the case of a 76-year-old man with a history of asbestos exposure who was diagnosed with left-sided malignant pleural mesothelioma in February 2010. The patient underwent chemotherapy with a combination of cisplatin and pemetrexed and achieved stable disease, after which time he was kept under observation...

Non-small cell lung cancer (NSCLC) is a major form of cancer and is resistant to chemo- and radio-therapy. Vicenin-2 (VCN-2) is a flavonoid obtained from Ocimum sanctum L. and it has been reported to have radioprotective and anti-cancer properties. This study was conducted to check for the radiosensitizing potential of VCN-2 in the NSCLC cell line, NCI-H23. NCI-H23 cells were exposed to VCN-2 singularly, and to X-rays with and without prior VCN-2 treatment. Cytotoxicity assay, cell proliferation assay, caspase-3 activity assay, DNA fragmentation assay and Western blotting for Rad50, MMP-2 and p21 were performed to investigate the radiosensitizing properties of VCN-2...

People living with HIV (PLWH) are diagnosed with cancer at an increased rate over the general population and generally have a higher mortality due to delayed diagnoses, advanced cancer stage, comorbidities, immunosuppression, and cancer treatment disparities. Lack of guidelines and provider education has led to substandard cancer care being offered to PLWH. To fill that gap, the NCCN Guidelines for Cancer in PLWH were developed; they provide treatment recommendations for PLWH who develop non-small cell lung cancer, anal cancer, Hodgkin lymphoma, and cervical cancer...

Acquired hemophilia A (AHA) is a rare disease, defined by the production of anti-factor VIII antibodies causing disordered hemostasis. It is idiopathic in 50% of cases, but sometimes associated with solid tumors. We report a case where AHA led to the diagnosis of lung cancer. CASE REPORT: An 82-year-old man with spontaneous hematomas on his trunk and extremities, and isolated prolongation of activated partial thromboplastin time was admitted to the emergency room. A severely reduced factor VIII level and a high factor VIII inhibitor title confirmed the diagnosis of AHA...

BMI-1 (B-lymphoma Mo-MLV insertion region 1) is a key protein partner in polycomb repressive complex 1 (PRC1) that helps in maintaining the integrity of the complex. It is also a key player in ubiquitination of histone H2A which affects gene expression pattern involved in various cellular processes such as cell proliferation, growth, DNA repair, apoptosis and senescence. In many cancers, Overexpression of BMI1correlates with advanced stages of disease, aggressive clinicopathological behavior, poor prognosis resistance to radiation and chemotherapy...

BACKGROUND: Stereotactic body radiotherapy (SBRT) has emerged as a highly effective technique to treat medically inoperable non-small cell lung cancer (NSCLC). Doses must be chosen carefully when treating central lesions because of the potential for significant toxicity. This study reviews the outcomes of a cohort of patients with central lung tumors treated with SBRT. METHODS: We identified 18 patients (12 women, 6 men) with central lesions that were treated with SBRT at our institution...

BACKGROUND:  Prognosis in limited disease small-cell lung cancer (SCLC) after concurrent chemoradiotherapy is poor. While some studies show better survival after multimodality treatment including surgery, other trials failed to prove a surgery-related survival benefit. Therefore, this study investigated survival in stage IA-IIIB SCLC following surgery combined with chemotherapy and/or thoracic radiotherapy. METHODS:  We retrospectively reviewed all stage IA-IIIB SCLC patients without supraclavicular lymph node involvement at a single institution between January 1999 and August 2016 after multimodality treatment with curative intent...
