Better treatment of esophageal cancer occurs with immunotherapy

Esophageal cancer arises, when cells in the lining of the esophagus grow uncontrollably and eventually form a tumour. Immunotherapy has been a promising development in the past few years. The recent activities have increased our understating of the tumour microenvironment, various immune combination therapies (like chemotherapy with immunotherapy).

Esophageal cancer is the seventh most common incident cancer across the world. 16,470 new cases and 14,530 death cases are estimated in the U.S with esophageal cancer. This extends from north-eastern China to the Middle East, including India, Iran and many more countries. There are various subtypes of this cancer, including Adenocarcinoma, lower part of the esophagus while Squamous cell carcinoma, upper part of the esophagus.

The stages of esophageal cancer involve, Stage 0 (abnormal cells are found only in the inner layer of the esophagus. It's called carcinoma in situ), Stage I (Through the inner layer to the sub mucosa), Stage II (Through the inner layer to the sub mucosa, spread to lymph nodes and invaded the muscle layer), Stage III (Through the outer layer, Spread to lymph nodes and invaded nearby structures) and Stage IV (Spread to distant organs, such as the liver)

Symptoms of esophageal cancer that involves pain in the throat, chronic cough, vomiting, pain in the breastbone. Risk factors for this cancer include tobacco chewing, cigarette smoking, alcohol habits and bad diet.

Treatment of esophageal cancer by using immunotherapy are classified into several types that involves monoclonal antibodies, vaccines, adoptive T cell transfer, adjuvant immunotherapy’s, and cytokines. There is no Food and Drug Administration (FDA) approved drugs in immunotherapy, but various are running in clinical trial for treatment of esophageal cancer.

Tumour Infiltrating Lymphocytes (TIL) are running in phase II trial by taking enriched tumour-infiltrating immune cells and re-infusing them in patient’s esophageal cancer. Sorafenib, it blocks the enzyme Rapidly Accelerated Fibrosarcoma (RAF) kinase, a critical component of the RAF signalling pathway that controls cell division and proliferation. Bevacizumab, A recombinant humanized monoclonal antibody directed against the Vascular Endothelial Growth Factor Receptor (VEGFR), a pro-angiogenic cytokine. Anti-VEGFR2 CAR CD8 plus PBL is running in phase I/II study of chimeric antigen receptor (CAR) T cells designed to target VEGFR2 for esophageal cancer.

Global Allied Pharmaceuticals (GAP) has been providing complete services of immunotherapy and immune-oncology. These therapies are used in the treatment and saves lives of cancer patients.
