Non-small cell lung cancer (NSCLC) remains the leading cause of cancer-related mortality worldwide.1Â Over the past two decades, the molecular characterization of NSCLC has transformed the therapeutic landscape by enabling the development of targeted therapies that have significantly improved outcomes ...
Cholangiocarcinoma (CCA) is a cancer of the epithelial cells lining the biliary tree in the liver and can occur both inside the liver (intrahepatic CCA [iCCA]) and outside the liver (extrahepatic CCA, which includes both perihilar and distal cholangiocarcinoma) (Figure 1). ...
Cancers of the oesophagus and oesophagogastric junction (OGJ), termed upper gastrointestinal (UGI) cancers, are lethal and constitute a significant public health problem. In 2020, 604,000 cases and 544,000 UGI cancer-related deaths were estimated worldwide.1Â UGI cancers are the seventh most frequently diagnosed cancer ...
Gastro-oesophageal cancers (GEC), which include both gastric (GC) and oesophageal cancers (EC), are among the most common cancers globally.1Â In the USA, the American Cancer Society estimated 20,640 new diagnoses of EC and 26,380 new diagnoses of GC, each contributing to 16,410 and 11,090 ...
Cholangiocarcinomas (CCAs) are a heterogenous group of cancers arising from the biliary epithelium. While they account for around 3% of all gastrointestinal malignancies, they are the second most common primary liver cancer.1Â CCAs tend to metastasize and have early lymph node ...
Cholangiocarcinoma constitutes approximately 3% of all gastrointestinal malignancies, and the incidence is on the rise, especially the intrahepatic subtype. These tumors are anatomically broadly classified into intrahepatic, perihilar, and distal cholangiocarcinoma. Recent understanding of tumorigenesis pathways has shown that there exists ...
In 2015, more than 430,000 people in the US were living with lung cancer and there were around 221,200 new cases of lung cancer. Deaths from lung cancer are estimated to be in the region of 158,040.1 Lung cancer is the most frequent cause ...
H-Ras, K-Ras, and N-Ras are the main members of Ras superfamily, which bind small molecules GTP and GDP interchangeably and can hydrolyze GTP to GDP. The Ras superfamily consists of more than 150 proteins and these can be classified under at ...
More than 350 cancer genes have been identified to date (see www.sanger.ac.uk/genetics/CGP) using a combination of epidemiological, genetic, and laboratory techniques. Decades of research into cancer genes have established some basic principles of tumorigenesis, including the ...
Breast cancer treatment has entered the translational era with the increasing emergence of rationally designed molecular therapeutics, particularly those that target members of the epidermal growth factor receptor (EGFR)/human epidermal growth factor receptor (HER) family. The HER-2-targeted agents ...
Squamous cell cancers of the head and neck (SCCHN) include a range of diseases consisting of cancers of the lip, gums, tongue, salivary glands, other oral cavity sites, nasal cavity, paranasal sinuses, pharynx and larynx. Locally advanced (LA) SCCHN tumours ...
EGFR and HER-2 in Breast Cancer The EGFR/HER family of tyrosine kinases plays an important role in the development and progression of breast cancer.1 It includes four known members: EGFR (HER-1 or erbB1), HER-2 (neu or erbB2), HER-3 (erbB3) ...
The Epidermal Growth Factor Receptor Family EGFR was the earliest of four receptors discovered in the ErbB family of receptor tyrosine kinases.1,2 Furthermore, it was this receptor that first identified a relationship between an activated oncogene and malignant transformation.3 This 170...
The median time to diagnosis of CNS metastatic disease is two years after the initial diagnosis of breast cancer, and it is unusual for it to be the only site of metastatic disease.8,9 Systemic disease used to be the leading ...
Trastuzumab is a recombinant humanised monoclonal antibody directed against the extracellular domain of the HER-2 protein. There are several mechanisms by which trastuzumab exerts its action, including:induction of receptor downregulation/degradation;4 prevention of HER-2 ectodomain cleavage;5 inhibition of HER-2 ...
The process of cellular differentiation, proliferation, and apoptosis is a tightly regulated one with multiple interactions within the cell and the surrounding extracellular matrix. A simplistic schema of intracellular signaling is shown in Figure 1. Disruption of one or more components ...
Factors that predict outcome in relapsing patients include previous complete response (CR), non-mediastinal primary, low serum tumour markers and no visceral metastasis. High-dose chemotherapy (HDCT) plus peripheral blood stem cell transplantation (PBST) can help patients who relapse after conventional chemotherapy, ...
