    Varubi is a tablet administered an hour or two prior to the start of chemotherapy to help prevent the nausea and vomiting that can be a side effect of this cancer treatment by blocking the signals to the brain that trigger these symptoms. It is an antiemitic medication containing rolapitant; it is usually given with other antiemitics. Varubi's side effects may include dizziness, hiccups, stomach pain, and decreased appetite. Varubi should not be used with the tranquilizers thioridazine or pimozide. It may also interact with other drugs and supplements like St. John's wort, rifampin, and digoxin. The doctor should be alerted as to all other drugs and supplements the patient is taking. Varubi may lower white blood cell counts, leading to greater chance of infection. It should not be taken more frequently than once every two weeks.

    Opdivo (nivolumab) is a drug approved for use in fighting advanced kidney cancer, advanced non-small cell lung cancer, and inoperable or advanced melanoma skin cancer. It is an intravenous drug, infused over an hour. Dosage varies according to the type of cancer treated, and may be prescribed with other drugs. Side effects may include cough, nausea, and tiredness. Opdivo may cause fetal harm, and is only advised for use during pregnancy if necessary. Women are advised not to breastfeed while being treated with Opdivo. It is not approved for use in children. Opdivo can cause harsh effects on the immune system during treatment. Patients treated with Opdivo who suffer chest pain, shortness of breath, abdominal pain, diarrhea, jaundice, rash, difficulty breathing, blood in the urine, headache, stiff neck, or other concerning symptoms should contact their doctor immediately.

    After treatment for cancer, living takes on different meaning. Cancer survivors need to transition from cancer treatment to maintaining a schedule of regular checkups and a healthy lifestyle. Even though they have had a cancer diagnosis and have completed their treatment, they must remain vigilant about their health.

    Greater awareness of early detection, better screening techniques and advanced treatments have lead to improved survival rates. Once people with cancer get through their treatment, many just want to move on with their lives. But they need help re-entering the world of primary care and regular health maintenance. As more people survive cancer, they should also have the guidance and support to help them embrace their lives once again. Such help can be found in support groups and survivorship programs.

    Typically the best candidates for treatment with interventional oncology using types of minimally invasive techniques are those people that had either very minimal disease or very early stage disease, such as very early stage I lung cancer. It can also be used for people who are at the opposite end of the spectrum and have metastases where the cancer has spread, usually from something like the colon to the liver. In these cases, the cancer is treated before it spreads elsewhere or before it causes liver failure, causing the person to pass away. Interventional oncology treatments are used early on and late.

    In treating cancer with ablation, a treatment probe is guided directly into a tumor using imaging, like computerized tomography (CT) or ultrasound. It’s like a biopsy, but instead of taking out tissue, a special type of needle or antennae is used to either burn or freeze the tumor. The hope of ablation is to replace the need for surgical resection.

    Interventional oncology therapies fall into two main categories. One is a vascular-based therapy where treatments placed into the blood vessels are carried to the part of the body that has the tumor. The other category is ablations, where the tumor is punctured directly and killed.

    The most common types of cancer treated with interventional oncology are gastrointestinal (GI) tract cancers. Usually that's colon cancer, which is very common. There are other forms of cancer called neuroendocrine cancers or carcinoid cancers. Typically when these cancers spread to the liver, interventional oncologists get involved in treating those liver metastases.

    Another very common cancer that we get involved with is primary lung cancers, typically associated with people who smoke. In those people that cannot undergo a surgical resection of their lung cancer, interventional oncologists can go in and ablate or burn that tumor so these people do not have to undergo surgery.

    Targeted therapy for cancer is a type of chemotherapy that is directed at specific molecules in cancer cells involved in the cancer's growth and spread. Unlike other chemotherapy agents that stop the growth of all rapidly dividing cells, both healthy and cancerous, targeted therapies zero in on specific cells involved in certain types of cancer. In this way, targeted therapy can treat cancer while causing fewer side effects and sparing damage to healthy cells.

    Targeted therapies that have been approved for treating cancer include the following, according to the National Cancer Institute:
    • Hormone therapies that stop the body from producing specific hormones, or that block the action of certain hormones, have been approved to treat some hormone-sensitive breast and prostate cancers.
    • Signal transduction inhibitors are drugs that can block the activity of certain molecules that signal some types of cancer cells to divide.
    • Gene expression modulators modify the function of proteins that play a role in controlling gene expression in certain types of cancer.
    • Apoptosis inducers are drugs that target and kill specific cancer cells.
    • Angiogenesis inhibitors block the growth of new blood vessels to cancer cells, cutting off the oxygen and nutrients that cancer cells need to grow.
    • Immunotherapies are drugs that trigger the immune system to fight cancer cells more successfully.
    • Monoclonal antibodies are specific drugs that can bind to and kill certain cancer cells while leaving healthy cells unharmed.
    Targeted therapies can cause some side effects (skin rashes, high blood pressure, wound healing problems), and are not available for use in all types of cancer. However research into targeted therapies for cancer is ongoing

    A Gastroenterology, answered on behalf of
    Why Are GI Stents Sometimes Used with Cancer Patients?
    Doctors may place stents in a patient's gastrointestinal (GI) tract to increase the comfort in patients who have cancer. In this video, gastroenterologist Harsha Vittal, MD, of Good Samaritan Hospital says stents can help patients avoid surgery.
