- Brain metastases or spinal cord compression. Patients with suspected brain metastases at screening should have an MRI (preferred) or CT each preferably with IV contrast of the brain prior to study entry or brain metastases or spinal cord compression unless the patient is stable (asymptomatic; no evidence of new or emerging brain metastases; and stable and off steroids and anti-convulsants for at least 14-28 days prior to start of study treatment). Following radiotherapy and/or surgery of the brain metastases patients must wait 4 weeks following the intervention to confirm stability.

- Fatigue, which may be serious
- Nausea, which may be serious requiring medical intervention
- Diarrhea, which may be serious requiring medical intervention
- Decreased/loss of appetite
- Itchiness
- Rash
- Vomiting, which may be serious requiring medical intervention
- Low thyroid function, which can be serious or life threatening. This may cause fatigue, weight gain, fluid retention, sensitivity to cold, and mental apathy.
- Joint pain, which may be serious
- Abnormally high levels of enzymes produced by the liver, meaning that your liver is not functioning properly. This may cause faigue and jaundice (yellowing of the skin and eyes). Although this is usually mild and reversible, this can be serious or life threatening.
- Muscle pain
- Difficulty breathing or shortness of breath, which may be serious requiring medical intervention
- Fever, which may be serious requiring medical intervention
- Cough
- Low red blood cell count, which can cause tiredness and shortness of breath. This may require a blood transfusion.
- High thyroid function, which may require medical intervention to resolve symptoms. This may cause weight loss, rapid heartbeat, sweating, trouble with heat, and nervousness.
- Weakness
- Fluid in the space surrounding the lung, which can cause shortness of breath. If severe, it may require hospitalization and treatment.
- Inflammation of the lung (pneumonitis), which can cause shortness of breath and difficulty breathing.
- Lung infection, which can be life threatening
- Inflammation of the large intestine (colitis) and the tube leading to the large intestine, which can lead to abdominal pain, diarrhea, and digestive problems. It can be life threatening or fatal.
- Blockage in the small intestine, which can lead to abdominal pain, constipation, and digestive problems.
- Failure to produce hormones (hypopituitarism), which can affect body functions such as metabolism, bone and tissue growth, and urine production.
- Low white blood cell count, which leads to an increased risk of infection.
- Lack of muscle control during walking or picking up objects
- Dehydration, which may be serious requiring medical intervention
- Sudden decrease in kidney function, which may cause swelling in your ankles, vomiting, weakness, poor sleep, and shortness of breath.
- Elevated level of glucose (sugar) in your blood, which can require hospitalization and urgent treatment (such as with diabetes).
- Central nervous system inflammation, which can cause irritation and swelling of brain tissue or blood vessels and result in confusion, hallucinations, difficulty walking or using arms.
- Abnormal heart beat (arrhythmia) which can cause dizziness, fainting, shortness of breath, chest discomfort, weakness, and fatigue.
- Swelling of the tumor which can cause worsening of tumor related problems and symptoms.
- Bleeding in the upper portion of the gastrointestinal tract, which may cause abdominal cramps, dizziness, and shortness of breath.
- Constipation
- Abdominal pain or cramps, which may be serious requiring medical intervention
- Weight loss
- Headache
- Anemia is a condition in which your body does not have enough healthy red blood cells. Symptoms can include fatigue, lightheadedness, dizziness, and may require a transfusion.

- Insomnia
- Back pain
- Pain in the extremities (arms, legs, wrists, ankles, shoulders, or neck)
- Dizziness
- Muscular pain in the chest
- Upper stomach pain
- Low levels of potassium in the blood, which can cause an abnormal heart rate. This could cause an irregular heartbeat, which can be serious and life threatening.
- Lung infection

- Confusion
- Sudden death caused by symptoms that might be consistent with decreased blood flow to the heart.

- Irritation, redness, and discoloration of the skin in the radiation area
- Decreased blood counts, which may cause shortness of breath, dizziness, and fatigue.
- Low platelet count, which may cause an increase in your chance of bleeding (nosebleeds, bruising, stroke, and/or digestive system bleeding). You may need a platelet transfusion.
- Slow wound healing
- Indigestion, which may cause abdominal pain, bloating, nausea, and vomiting.
- Gastritis, which may cause heartburn, indigestion, nausea, and vomiting.
- Radiation esophagitis, which may cause inflammation, irritation, or swelling of the esophagus (the tube that leads from the back of the mouth to the stomach).
- Rib microfracture due to radiation, which may cause chest or back pain, and pain when coughing, sneezing, and moving.
- Damage to the liver which could result in inflammation and scarring oft he liver. This could lead to jaundice and possibly cirrhosis (a chronic condition where the liver functions poorly leading to fatigue, weakness, fluid retention in the abdomen, and other complications). Efforts to prevent extensive liver irradiation will be taken to minimize the chance of these side effects.
- Mucosal ulceration is an ulcer in the mucous membrane that lines various internal organs.
- Tissue damage due to radiation, which may require surgery and may be life-threatening.
- The stomach, kidneys, and bowel are well-protected from excessive radiation. Therefore injury to these organs is unlikely. However, overdosing the stomach or bowel can lead to ulceration or perforation. Pain, inflammation, or scarring of the kidneys, stomach, or bowel may rarely occur.

- Spinal cord injury due to radiation, which may cause numbness.
- Rare development of second tumors due to radiation
