PHOTODYNAMIC THERAPY BASED COMBINATION THERAPY APPLICATION FOR OVARIAN CANCER
Öz
Cancer is one of the most
leading causes of death in Turkey as well as in the world. It is very critical
to cure the cancer via targeted therapy that is locally applied and shows minimum
side effects for patient’s life quality.
Photodynamic therapy (PDT) is a local, photochemistry based treatment,
which has minimum side effects. In
brief, PDT is a result of a combination of photosensitizer, a drug that is
activated by light, light and oxygen that generates free radicals and/or
singlet oxygen and starts series of reactions in cell and eventually cause cell
death. While light, oxygen and photosensitizer has no cytotoxic effect alone,
combination of three starts all photochemical reactions and as a result
cytotoxicity is generated in the tissue. Photosensitizer, converting light
energy to the chemical energy in the cell, is the most critical component of
PDT. One way to improve effectiveness of PDT is to combine it with different
treatment modalities. Cancer and other degenerative diseases involve several pathological
mechanisms and require multiple treatment methods such as combination
therapies. A combination therapy targets to bring together current therapies
and/or drugs to act upon different cellular signaling pathways/ cell damage
pathways thus activating various mechanisms in the cell increasing the success
rate of the treatment. In the light of
these information, a new combination
therapy, based on PDT and chemotherapy, has been investigated towards SKOV-3
over cancer cell line. A novel and
water-soluble photosensitizer and a chemotherapy drug called Irinotecan that is
been used in clinic were employed. Our
results showed that outcome of the combination therapy, which is composed of
PDT and chemotherapy, highly depends on the order of the treatment. For
instance, when PDT applied first, strong antagonism is observed at certain drug
concentrations. On the other hand, synergism is observed using the same drug
concentrations yet by only changing the order of the treatment.
