Optimal management of NSCLC now requires that tumours be screened for a certain range of predictive and prognostic biomarkers that help to predict sensitivity to targeted therapy and estimate prognosis respectively . For NSCLC, much of the work in the past years has been focussed on mutations of the epidermal growth factor receptor (EGFR) and on the abnormal fusion of the anaplastic lymphoma kinase (ALK) being inhibited successfully with EGFR tyrosine kinase inhibitors (TKI) and crizotinib respectively. Targeted agents are now being rationally designed to inhibit particular mutations leading to a more streamlined clinical trial process. In this review, we will examine the major subtypes of driver mutations that have been identified in NSCLC and relevant targeted therapies available both now, and in the foreseeable future.

The defining goal is to eliminate all evidence of the cancer cells with the use of cytotoxic agents. Chemotherapeutic agents are chosen because of their ability to interfere with oncologic cell division. The treatment of ALL involves 3 phases: remission induction, consolidation, and maintenance therapy. Pediatric patients with ALL are often given 8 or more months of intensive chemotherapy. This is often followed by maintenance therapy of two or more years (Gedaly-Duff et al., 2006). Most treatment protocols use systemic chemotherapy with or without radiotherapy (McCance & Huether, 2010).  According to a study conducted by McDonald & Mc Carthy (2005), success of chemotherapy and remission depends on “aggressive induction chemotherapy followed by delayed intensification and maintenance therapy, p. 809.”

In this issue of Lancet Oncology, Dr. Antonia and colleagues report on the combination of durvalumab and tremelimumab in patients with non-small cell lung cancer (NSCLC).1 After the recent approvals of nivolumab and pembrolizumab in NSCLC,2, 3, 4 there is a near frenzy of attempts to combine agents with inhibitors of the PD-1 immune checkpoint. Some efforts are based on only the shakiest of scientific evidence. However, the combination of durvalumab, a PD-L1 inhibitor, and tremelimumab, a CTLA-4 inhibitor, has a sound scientific basis. Dual checkpoint inhibition is now an established treatment option for patients with advanced melanoma.5, 6

Epithelial-mesenchymal transition (EMT) is a cellular process that is essential for normal processes in many organisms, including embryonic development and wound healing, and is recapitulated in human disease, contributing to organ fibrosis and cancer progression (Thiery et al. 2009; Yang and Weinberg 2008). EMT describes the conversion of a cell with an epithelial phenotype to one with mesenchymal characteristics and can be a partial or complete transformation. Epithelial cells form the borders of tissues and organs, and are characterized by apical-basal polarity, contact with a basement membrane, and strong adherence to other epithelial cells through intercellular junctions including adherens junctions, tight junctions, and desmosomes. Conversely, mesenchymal cells have front-rear polarity and generally lack cell-cell contact, allowing them to be motile. During human embryonic development, EMT is essential for the formation of a variety of tissues, including mesoderm, neural crest, somites, palate, pancreas, liver, reproductive tracts, and heart valves (Thiery et al. 2009; Yang and Weinberg 2008). After development, partial EMT also contributes to wound healing (Thiery et al. 2009). However, EMT can also play a more insidious role by factoring into tumour progression.

Currently, locoregional therapies play an important role in the treatment of patients awaiting LT. For patients listed within the (stage T2-HCC), a delay of LT over 6-12 months without bridging treatment is a well-recognized risk factor for tumor progression and dropout from the list or interval dissemination with post-transplant tumor recurrence. (Freeman RB et al., 2006).

Cancer is the second largest cause of death in the United States of America, overall, according to the CDC, clocking in at around 575,691 lives in 2013 alone. Countless people have been affected or know someone who has been affected by cancer, and the search for a cure has been raging on for decades. Renal cancers, or cancer of the kidneys, the two bean shaped organs located to the right and left adjacent to a person’s spine, is the fifth most common form of cancer within the United States, affecting too many, too often. Often overshadowed by the greater publicized cancers, this often deadly disease’s information is not as widely known to the public as it should be to help combat this harmful cancer, and help those who are harmed by it.

Congress and policy makers should lift restrictive laws and clauses that hinder an addict’s rehabilitation process, and instead promote more readily available treatment by requiring insurance companies to contribute funding and grants that promote long term recovery. Insurance companies must be held accountable in order for long term recovery to be an attainable goal with addicts. However, this is not a popular notion amongst insurance companies, who prefer to put severe caps on treatment. Insurance companies evade paying for the treatment of substance addicted patients due to high cost of ministration: “Last year, Representative Tom Price of Georgia, Trump’s nominee for secretary of health and human services, put forward an alternative that

For many types of cancers, we have been using the same base drug (first line treatment) for ten years or even longer. As companies find new drugs to fight the cancers, they hope that it will be the miracle drug that will eradicate the cancer, but it usually isn’t. When they reach this conclusion, instead of returning to the chalkboard and continuing to work to improve the drug, they put the drug on the market as is, and hope it will achieve something. Not only are they putting these drugs on the market but they put price tags on them that would bankrupt anyone without some sort of third party payer. The combination of all of these drugs make up what doctors

You never know how long it is going to take for the tumor to go away, if at all. Dealing with AT/RT cancer, although it normally appears in younger children, treatment is almost always different for children and adults. You will need surgery as a step to rid the tumor. And chances of recovery or ways to cure it may depend on how much of the tumor is left after the surgery. To actually treat the cancer, you may do radiation treatment, chemotherapy, surgery, or high-dose chemotherapy with stem cell transplant. Although, patients with AT/RT cancer may want to think about taking part in a clinical trial, which is basically a research study. Just because you take treatment for the tumor, any tumor at most, it does not mean your tumor will disappear. Not everyone will be lucky enough to rid their tumor. In most cases people die from it. Luckily this tumor is one of the rares of them

MSKCC radiologist use state of the art imaging technology to detect cancer while the pathologists have unsurpassed experience in using advances methods to accurately diagnose cancer. This type of Innovative technology allows precise diagnosis and staging of the disease. Furthermore, it is easier to determine whether a specific form of treatments is working or not. In this case, physicians can therefore shift the treatment or consider alternative methods of treatment.

Follow up CT, MRI, or PET scans are employed to determine the size of the tumor, the extent of local invasion, and if distant metastasis has already occurred11. This is particularly important because, although all ATC cases are considered Stage IV cancers, the severity of metastasis dictates the course of treatment. Stage IVA cancers are limited to the thyroid and are often treated with surgical resection, if possible. This is followed by radiotherapy and chemotherapy9,11. For most patients, however, the cancer is unresectable. As such, clinicians typically shift their focus towards a combination of radiation therapy, chemotherapy, and palliative care to improve the quality of

Crizotinib (PF-02341066) is a potent inhibitor of c-Met and ALK. Anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC) is a molecular subtype of NSCLC with at least 27 ALK-fusion variants identified. c-Met is the prototypic member of RTKs, which is the only known high-affinity receptor for hepatocyte growth factor (HGF). Binding of HGF to the c-Met results in receptor multimerization and phosphorylation of multiple tyrosine residues at the intracellular region.

Acute treatment lasted until the patient met the criteria for remission, defined as 4 consecutive weeks of minimal symptoms; continuation treatment lasted to the point of recovery, defined as another 26 consecutive weeks without relapse. Patients did not need to maintain the symptom levels required for remission to meet the criteria for recovery. Participants who experienced relapse during continuation were required to meet remission criteria again before theywere eligible tomeetthe criteria for recovery. Patientswhodid notmeet the symptomatic criteria for remission within 18 months of treatmentwere removed fromthe study and referred for other treatment, as were patients who did not meet criteria for recoverywithin 36 months.
