Chemotherapy can boost tumor immunity in two main ways: (a) by killing cancer cells through immunogenic cell death, and (b) by affecting both cancerous and normal cells in the tumor environment. Despite this, many chemotherapy treatments can also suppress the immune system by causing lymphopenia or impairing lymphocyte function.
Medications that kill rapidly dividing cells or blood cells can reduce the number of platelets in the blood, which can result in bruises and bleeding. Extremely low platelet counts may be temporarily boosted through platelet transfusions and new drugs to increase platelet counts during chemotherapy are being developed.
To kill the same number of cancerous cells, neutrons require one third the effective dose as protons. [1] Another advantage is the established ability of neutrons to better treat some cancers, such as salivary gland, adenoid cystic carcinomas and certain types of brain tumors, especially high-grade gliomas [ 2 ]
A professor with the University of Texas at San Antonio has created a new method to kill cancer cells that are traditionally difficult to eradicate.
The resulting decay reaction yields high-energy alpha particles that kill the cancer cells that have taken up enough 10 B. All clinical experience with NCT to date is with boron-10; hence this method is known as boron neutron capture therapy (BNCT). [1]
Radiation therapy is used to kill cancer cells; however, normal cells are also damaged in the process. Currently, therapeutic doses of radiation can be targeted to tumors with great accuracy using linear accelerators in radiation oncology; however, when irradiating using external beam radiotherapy, the beam will always need to travel through healthy tissue, and the normal liver tissue is very ...
Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. [1] Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, [2] and PARP inhibitors such as olaparib.

An alkylating antineoplastic agent is an alkylating agent used in cancer treatment that attaches an alkyl group (C n H 2n+1) to DNA. [1] Since cancer cells, in general, proliferate faster and with less error-correcting than healthy cells, cancer cells are more sensitive to DNA damage—such as being alkylated. Alkylating agents are used to ...
