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.
The goal is to reduce the tumor population to zero with successive fractional kills. [3] For example, assuming a 99% kill per cycle of chemotherapy, a tumor of 10 11 cells would be reduced to less than one cell with six treatment cycles: 10 11 * 0.01 6 < 1. [3] However, the tumor can also re-grow during the intervals between treatments ...
Performance status is often used as a measure to determine whether a person can receive chemotherapy, or whether dose reduction is required. Because only a fraction of the cells in a tumor die with each treatment (fractional kill), repeated doses must be administered to continue to reduce the size of the tumor. [10]
Nearly a third of patients with advanced liver cancer who received a personalized vaccine developed by Geneos Therapeutics along with an immunotherapy drug in a small, early trial saw their tumors ...
TACE of liver tumors derives its beneficial effect by two primary mechanisms. [3] Most tumors within the liver are supplied by the proper hepatic artery, so arterial embolization preferentially interrupts the tumor's blood supply and stalls growth until neovascularization. Secondly, focused administration of chemotherapy allows for delivery of ...
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.

Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
Neoadjuvant platinum-based chemotherapy has been demonstrated to improve OS in advanced bladder cancer, but there exists some controversy in the administration. [25] Unpredictable patient response remains the drawback of NAC therapy. While it may shrink tumors in some patients, others may not respond to the treatment at all.
