Sunitinib
About Sunitinib
Sunitinib belongs to the class of medications called ‘antineoplastic agents’ used in treating gastrointestinal stromal tumors (cancer of the stomach, bowel, or esophagus) in which patients don’t respond to imatinib (another anticancer agent). It is also used to treat renal carcinoma (kidney cancer) that has spread to other parts of the body and advanced pancreatic neuroendocrine tumors (cancer that has affected hormone-producing cells in the pancreas).
Sunitinib contains sunitinib. It acts by slowing down the growth of cancer cells by two processes. It interferes with the action of a protein that promotes cell division and thereby decreases cancer cell production. It can inhibit a process called angiogenesis, the development of blood supply to the cancer cells. This effect inhibits the nutrient supply to the cancer cells, thereby causing cancer cell death eventually.

Do not consume alcohol as it may increase the risk of side-effects. Sunitinib may cause dizziness, so do not drive or operate heavy machinery if you are not fully alert.
Uses of Sunitinib
Medicinal Benefits
Sunitinib is a targeted therapy used to treat advanced kidney cancer. It is also used in patients with kidney cancer to prevent recurrence after having kidney surgery. It is used to treat gastrointestinal stromal cancer that cannot be treated with imatinib, another anti-cancer medicine. It is used to manage pancreatic neuroendocrine tumors (cancer of hormone-producing cells of the pancreas) that cannot be treated with surgery. Sunitinib can help to manage the above conditions if taken regularly as prescribed by the doctor.

Sunitinib should be used with caution in patients with aneurysm (weakening of blood vessel wall), thrombotic microangiopathy (damage to the small blood vessels), and liver or kidney problems. Sunitinib may cause inflammation of the pancreas or gallbladder and lead to symptoms such as abdominal pain (upper abdominal region), fever, and vomiting, in patients with a history of pancreatic or gallbladder disorders. Sunitinib may cause thyroid gland problems, so inform your doctor if you experience frequent fatigue and extreme cold than others. Sunitinib may cause skin ulceration (pyoderma gangrenosum) or infection (necrotizing fasciitis). So, inform your doctor if you notice symptoms of infection around a skin injury such as fever, pain, swelling, redness, and drainage of pus or blood from the wound. However, these effects are usually reversible after the discontinuation of therapy. If you develop severe skin rashes, especially with blistering or peeling of the skin, notify your doctor immediately as it can be a sign of a serious skin condition.

Patients Concern
Disease/Condition Glossary
Gastrointestinal stromal tumor: It is cancer that affects the stomach and small intestine. It shows no or mild symptoms during the initial stages. It may cause blood in the stool or vomit as the disease progresses. In general, surgery is preferred for the treatment. However, imatinib or sunitinib (targeted therapy) can be given to shrink the tumor or if the tumor cannot be removed by surgery.
Kidney cancer: It is also called renal cell carcinoma. It is the most common type of cancer seen in adults. Symptoms include red, orange, or pink-colored urine due to the presence of blood in the urine. In advanced kidney cancer (that has spread to other parts of the body), treatment is given to improve the survival rate.
Pancreatic neuroendocrine tumors: It is a type of endocrinal tumor that arises in the pancreas. Symptoms include yellowish skin or whites of the eyes, diarrhea, indigestion, stomach pain, and weight loss. Surgery, hormonal therapy, chemotherapy, and targeted therapy can be given to treat this type of tumor.
FAQs
Sunitinib is used to treat gastrointestinal stromal tumours (cancer of the stomach, bowel, or oesophagus), renal carcinoma (kidney cancer) and advanced pancreatic neuroendocrine tumours (cancer that has affected hormone-producing cells in the pancreas).
Sunitinib contains sunitinib which is an anti-cancer medicine. It acts by slowing down the growth of cancer cells by two processes. It interferes with the action of a protein that promotes cell division and thereby decreases cancer cell production. It can inhibit a process called angiogenesis, the development of blood supply to the cancer cells.
