Objective The landscape of non-small cell lung cancer (NSCLC) has changed due to liberalized utilization of computed tomography, developments in immunotherapy and targeted treatments, and guidelines encouraging sublobar resections. We analyzed the implications of these advances for surgical procedures over a 16-year period. Methods The National Cancer Database was used to identify NSCLC incident cases from 2004 to 2020. Histology, stage, grade, and treatment were analyzed using descriptive statistics and logistic regression. Results 2,028,553NSCLC patients were identified. Each year was associated with an increase in Stage I for NSCLC (OR1.05, 95%CI 1.05-1.05) and histological subtypes (adenocarcinoma: OR1.03, 95%CI 1.03-1.04; squamous: OR1.02, 95%CI 1.02-1.02; neuroendocrine: OR1.11, 95%CI 1.11-1.12), with no change in adenosquamous histology. A similar increase was observed for well- or moderately-differentiated histology (OR1.04, 95%CI 1.04-1.04). The proportion of patients receiving chemotherapy decreased (OR0.98, 95%CI 0.98-0.98), while more patients were treated with immunotherapy or targeted therapy, including an increase of 14% using immunotherapy or targeted therapy as first-line treatment. There was a decrease in the likelihood of receiving pneumonectomy (OR 0.91, 95%CI 0.91-0.91). Despite guidelines advocating sublobar resections, these procedures only increased by 1.1% per year. Conclusions Over the 16-year study period, there was a significant trend towards diagnosis of Stage I NSCLC. The most pronounced change in treatment patterns has been more patients receiving immunotherapy and less chemotherapy. Despite a promising decrease in pneumonectomies, the frequency of sublobar resections remains stagnant, indicating limited uptage in current practice.

Using samples of small cell lung tumors, a research team led by biologist Dr. Raymond discovered two new ways to induce tumor cell death. By activating ferroptosis, one of two subtypes of tumor cells can be targeted: first, iron-dependent cell death due to oxidative stress, and second, oxidative stress. Therefore, cell death can also be induced in a different way. Both types of cell death must be caused by drugs at the same time to eliminate the majority of the tumor mass. It is currently in clinical trials for cancer treatment. Auranofin, which inhibits the production of protective antioxidants in cancer cells, has been used to treat rheumatoid arthritis for decades. Future clinical trials using this combination therapy will determine the extent to which this targeted treatment option improves the prognosis of small cell lung cancer patients. It is currently in clinical trials for cancer treatment. Lung cancer is the leading cause of cancer death in the United States. Despite evidence of molecular abnormalities in biological specimens, progress in this disease is hampered by the lack of diagnostic markers useful for clinical practice. The majority of patients with lung cancer are still diagnosed at an advanced stage, when prognosis is poor. This article reviews new strategies being studied for the early detection of lung cancer. These strategies involve new methods of imaging (including low-dose computed tomography CT scanning), DNA analysis, and proteomic-based techniques. These strategies have not only improved our understanding of lung cancer but show promise in offering better survival to patients with this deadly disease. Of paramount importance in the search for methods of early detection is the need for the identification of the ideal population to screen, a multidisciplinary approach, and validation of promising techniques.

Metastatic melanoma is a very deadly type of skin cancer with poor prognosis and low 5-year survival rates. Until recently, patients with metastatic melanoma had very few treatment options, which only included dacarbazine and aldesleukin. In 2011, the first checkpoint blocker, ipilimumab was approved for the treatment of unresectable metastatic melanoma but its success was eclipsed by low response rates and high incidence of adverse events. Later in 2014, anti-PD-1 antibodies, nivolumab and pembrolizumab were approved for the treatment of metastatic melanoma. With comparatively high response rates and manageable safety profile, PD-1 blockers were remarkably successful in the treatment of melanoma and also other cancer subtypes such as non-small cell lung cancer and metastatic urothelial carcinoma. This article highlights the success of anti-PD-1 antibodies, discusses the mechanism of PD-1:PD-L1/2 pathway, responses of melanoma patients to PD-1 blockers and the research on improving response rates to PD-1 blockers.

Non-small cell lung cancer is a major health problem worldwide. Surgery is still the mainstay of treatment especially in early stages of the disease. Despite the fact that surgery is the potentially curative treatment, the recurrence and mortality rates are still high specifically with more advanced stages of cancer. Heparin has been suggested to have a positive impact on the outcome of various cancers through its anticoagulants properties and; in some instances; due to their antitumor activity. Recently, the molecular mechanisms of tumor cell spreading have been recognised. Metastasis is a complex process that could be therapeutically affected wherever certain extra-cellular matrix proteins could play an important role in prevention of tumor cell migration and invasion. Experimental studies have shown decreased metastases development after heparin use in rat models. We have reviewed the literature to study the role of anticoagulants in cancer patients in general and in patients with Non Small Cell Lung Cancer (NSCLC) specifically.
