Abstract:
A 46-year-old woman presented with a peripheral vasoproliferative tumor. The tumor was treated with one session of photodynamic therapy with 6 mg/m2 body surface area of verteporfin and a dose of 100 J/cm2 delivered in 83 seconds. At the 10-month follow-up examination, involution of the vasoproliferative tumor was seen with improvement of best-corrected visual acuity to 20/80. Photodynamic therapy is an effective treatment option in cases of exudative vasoproliferative tumors. Great variability exists in the parameters used to treat vasoproliferative tumors.

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
02:49Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
