RRx-001 in Refractory Small-Cell Lung Carcinoma: A Case Report of a Partial Response after a Third Reintroduction of Platinum Doublets.

RRx-001 is a pan-active, systemically nontoxic epigenetic inhibitor under investigation in advanced non-small cell lung cancer, small-cell lung cancer and high-grade neuroendocrine tumors in a Phase II clinical trial entitled TRIPLE THREAT (NCT02489903), which reexposes patients to previously effective but refractory platinum doublets after treatment with RRx-001. The purpose of this case study is first to report a partial response to carboplatin and etoposide in a patient with small-cell lung cancer pretreated with RRx-001, indicating episensitization or resensitization by epigenetic mechanisms, and second to discuss the literature related to small-cell lung cancer and episensitization

The Diagnostic Accuracy of Chest CT in the Detection of Tumor and Nodal Status in Non Small Cell Lung Carcinoma

At this time there is an increasing demand for an accurate pre operative staging in non small cell lung cancer. Chest Computed Tomography (CT) is one of the imaging modality of choice used for this purpose. This study evaluated the accuracy of the chest CT to determine the status of the tumor and nodules in non small cell lung cancer. During the years 1998 and 1999, a descriptive prospective study of 32 patients undergoing a contrast enhanced chest CT examination for non small cell lung cancer, stage I-IIIA, was conducted. Lobectomy, lymph nodes dissection and postoperative histo-pathological examination were done. CT findings were as follows: a sensitivity of 100%, a specificity of 25% and an accuracy of 60% in the detection of the nodule stage were found. In 17 patients with adenocarcinoma, the sensitivity, the specificity and the accuracy were 86.6%, 100% and 88.2% respectively. The diagnosis of all patients was confirmed histo-pathologically. Six patients with T2 and 26 patients with T3 were detected by chest CT; the accuracy of the tumor status was 93.7%, confirmed by surgical and histo-pathological examinations. It was concluded that the CT played an important role in determining the clinical stage of non small cell lung cancer. The specificity and accuracy were higher in adeno-carcinoma as compared with squamous cell carcinoma in detecting the nodal status

Review of the use of ceritinib, a newly approved anaplastic lymphoma kinase (ALK) inhibitor, in crizotinib-resistant anaplastic lymphoma kinase-rearranged non-small cell lung cancer

Lung cancer is one of the most prevalent cancers in the United States, and is the leading cause of death related to cancer. Non-small cell lung cancer is the most common subtype, with approximately 85% of diagnosed lung cancer being non-small cell lung cancer. Several genetic mutations exist in patients with non-small cell lung cancer, which allows for specialized targeted therapy. One such mutation, EML4-ALK fusion protein abnormalities, represents roughly 5% of non-small cell lung cancer patients, but the patient population in which it is most prevalent is young adults and those that don’t smoke or have a short history of smoking. Ceritinib (Zykadia), a newly approved ALK tyrosine kinase inhibitor, shows exceptional potency against ALK mutations, and shows promise in the ability to overcome resistance that develops during crizotinib (Xalkori) therapy. Several studies are currently underway that are further evaluating the effectiveness of ceritinib in different areas of treatment for ALK-rearranged non-small cell lung cancer

Gemcitabine: Efficacy in the Treatment of Advanced Stage Nonsquamous Non-Small Cell Lung Cancer

Lung cancer is the leading cause of cancer-related death in many countries. Approximately half of the patients with non-small cell lung cancer have advanced disease and systemic chemotherapy, especially platinum-based doublets, is currently the standard treatment. Several trials have recently indicated the importance of histological subtype for treatment with molecular target chemotherapy and pemetrexed. Over the last decade, gemcitabine, a pyrimidine nucleoside antimetabolite, has been one of the most effective agents for patients with advanced non-small cell lung cancer. It is unknown whether histological type is a predictor of the outcome of treatment with this agent. This is a review of the past trials and reviews of first-line treatment for advanced NSCLC, focusing on efficacy and safety of treatment with gemcitabine according to histological subtype

PET/CT in the Staging of the Non-Small-Cell Lung Cancer

Lung cancer is a common disease and the leading cause of cancer-related death in many countries. Precise staging of patients with non-small-cell lung cancer plays an important role in determining treatment strategy and prognosis. Positron emission tomography/computed tomography (PET/CT), combining anatomic information of CT and metabolic information of PET, is emerging as a potential diagnosis and staging test in patients with non-small-cell lung cancer (NSCLC). The purpose of this paper is to discuss the value of integrated PET/CT in the staging of the non-small-cell lung cancer and its health economics

Prognostic impact of serum albumin levels on the recurrence of stage I non-small cell lung cancer

Objective: Patients with stage I non-small cell lung cancer who have undergone complete surgical resection harbor a 30% risk for tumor recurrence. Thus, the identification of factors that are predictive for tumor recurrence is urgently needed. The aim of this study was to test the prognostic value of serum albumin levels on tumor recurrence in patients with stage I non-small cell lung cancer. Methods: Stage I non-small cell lung cancer patients who underwent complete surgical resection of the primary tumor at Zhejiang Hospital were analyzed in this study. Serum albumin levels were measured before surgery and once again after surgery in 101 histologically diagnosed non-small cell lung cancer patients. Correlations between the pre- and post-operative serum albumin levels and various clinical demographics and recurrence-free survival rates were analyzed. Results: Patients with pre-operative hypoalbuminemia

Clinical profile and initial treatment of non-small cell lung cancer: a retrospective cohort study at the Uganda Cancer Institute

Introduction: Lung cancer is a major global public health burden constituting 11.6% of all new cancer diagnoses and 18.4% of all cancer-related mortality. Purpose: To describe the clinical profile and initial treatment of non-small cell lung cancer in Uganda. Methods: We reviewed charts of a cohort of patients with a histologically confirmed diagnosis of non-small cell lung cancer, treated between January 2013 and November 2015 at the Uganda Cancer Institute. Results: A total of 74 patients met the inclusion criteria. The median age was 56 years (IQR 47-70), with 16.2% below the age 45 years, and 51% were female. Only 10 percent were active smokers and the most frequent histological subtype was adenocarcinoma (71%). The majority (91.9%) had stage IV disease at diagnosis and frequent metastases to contralateral lung, liver, and bones. Twenty-seven (27) patients received platinum-based chemotherapy, while 27 patients received erlotinib, and only 4 patients received palliative thoracic radiotherapy. The median survival time was 12.4 months, and the overall response rate was 32.7%. There was no survival difference by type of systemic treatment, and on multivariate analysis, poor performance status was predictive of adverse outcomes (p < 0.001). Conclusions: Patients with non-small cell lung cancer in Uganda frequently presented with late-stage disease at diagnosis. The majority of patients were female, never-smokers, and had predominantly adenocarcinoma subtype. Keywords: Non-small cell lung cancer; Uganda; erlotinib; lung cancer; Uganda Cancer Institute

Detection of human telomerase reverse transcriptase mRNA in cells obtained by lavage of the pleura is not associated with worse outcome in patients with stage I/II non–small cell lung cancer: Results from Cancer and Leukemia Group B 159902

ObjectivePrevious studies suggest that cytologic analysis of cells obtained by lavage of the pleural surfaces at the time of resection of non–small cell lung cancer can identify patients at risk for recurrence. Because telomerase gene expression has been associated with worse outcome in non–small cell lung cancer, we hypothesized that identification of cells obtained from pleural lavage that express telomerase would identify patients at risk for recurrent disease.MethodsPatients with presumed non–small cell lung cancer underwent thoracotomy with curative intent. Cells obtained by lavage of the pleural surfaces were analyzed for telomerase catalytic subunit human telomerase reverse transcriptase mRNA expression using reverse transcriptase polymerase chain reaction.ResultsA total of 194 patients with stage I/II non–small cell lung cancer had adequate samples, and median follow-up was 60 months (17-91 months). By using Cox models, no statistical differences were found between human telomerase reverse transcriptase–negative and positive patients in disease-free survival (hazard ratio, 1.28; 95% confidence interval, 0.85-1.94; log-rank test, P = .2349) or overall survival (hazard ratio, 1.13; 95% confidence interval, 0.72-1.79; log-rank test, P = .5912)ConclusionsDetection of human telomerase reverse transcriptase in cells obtained from pleural lavage of patients with stage I/II non–small cell lung cancer does not identify patients at risk for recurrent disease

ANN for Predicting DNA Lung Cancer

Abstract: Lung cancer is the top reason of cancer-associated deaths globally. Surgery is the typical treatment for early-stage non-small cell lung cancer (NSCLC). Advancement in the knowledge of the biology of non-small cell lung cancer has shown molecular evidence used for systemic cancer therapy aiming metastatic disease, with a significant impact on patients’ overall survival (OS) and eminence of life. Though, a biopsy of overt metastases is an invasive technique restricted to assured positions and not effortlessly satisfactory in the clinic. The examination of peripheral blood samples of cancer patients embodies a new basis of cancer-derived material, recognized as liquid biopsy, and its constituents (circulating tumour cells (CTCS), circulating free DNA (cfDNA), exosomes, and tumour-educated platelets (TEP)) may be gotten from nearly any body liquids. These constituents have shown to imitate features of the status of both the primary and metastatic diseases, aiding the clinicians to go towards a tailored medicine. In this paper, the reasons of lung cancer will be recognized and the risk elements that initiated the increase of infection, for instance Smoking, Disclosure to secondhand smoke, Disclosure to radon gas, Disclosure to asbestos and other compounds, Family past history of lung cancer, and decrease of the spread of disease and approaches of handling and prevention of lung cancer
