Oncology

• Comprehensive Examination – Examination remains the fundamental tool in describing and staging cancer. As treatment progresses, serial comprehensive examinations allow the oncology team to track treatment progress.
• Molecular Diagnostics
• Digital Radiography – Unlike traditional x-rays, digital radiography provides highly detailed images that can be modified or enhanced. The exceptional resolution of digital radiographs provides much greater ability to identify disease.
• Diagnostic Ultrasound – Ultrasound is a technique where sound waves are used to image soft tissues of the body. Different soft tissues absorb and reflect sound waves differently, giving them a different appearance. Ultrasound allows practitioners to see inside a solid organ, distinguishing changes within the tissue. The ability to distinguish changes inside a solid tissue organ (e.g., the liver), along with the ability to guide a biopsy needle into an abnormal area, enables targeted biopsies to be obtained. Precision biopsies enable the oncology team to diagnose cancers early.
• Endoscopy – Endoscopy is a procedure where a small camera is placed inside body cavities to observe tissues to identify disease. Biopsies taken during endoscopic exam enable the oncology team to diagnose cancer. Areas where endoscopy is used include the nasal cavity, gastrointestinal tract, urinary tract, thoracic cavity, and abdomen. Endoscopic examinations are minimally invasive and are frequently done on an outpatient basis.
• CT Scans – CT allows us to better diagnose and treat cancers in the brain, spinal cord, spine, abdomen, chest, and pelvis than ordinary x-ray. CT scans are much more sensitive in identifying cancer or spread of cancer to the lungs or other tissues. The extremely fast image acquisition and reconstructions allows us to perform studies requiring only sedation rather than anesthesia, which may be important in very sick patients.
• MRI – MRI is a safe and non-invasive imaging technique that enables cancers to be diagnosed accurately and rapidly. MRI provides excellent detail for pre-operative planning for surgical excision of tumors. IndyVet utilizes the Hallmarq PetVet 1.5T high field MRI specifically designed for veterinary use. The unique dual coil system of the PetVet MRI provides a significant boost in signal intensity across larger body regions allowing fast scan times, which is important in cancer patients. IndyVet is proud to be the first to have this superior veterinary MRI system in the Midwest.
• Histopathology – Histopathology is a technique where tissue biopsies are stained, sectioned, and viewed under a microscope by a pathologist to describe disease. Biopsy with histopathology is the method of diagnosing and differentiating cancers from other diseases.
• Bone Marrow Biopsy – Bone marrow biopsy is performed by placing a needle into a bone to extract marrow. This is done to diagnose various types of bone marrow cancer (leukemias). Extracted bone marrow is stained and viewed by a pathologist allowing description of the specific type of bone marrow cancer. Different types of bone marrow cancer require vastly different types of drugs for treatment.

Chemotherapy is drug therapy designed to kill or slow the growth of cancer cells. Many of the drugs used to treat cancer in pets are derived from natural substances found in plants, trees, or bacteria and are often the same drugs used in people. Chemotherapy is frequently used to treat cancer that has spread to other parts of the body, to treat cancer that cannot be treated with surgery or radiation therapy alone, or when it may enhance the effectiveness of other treatments.

The word chemotherapy often brings to mind images of patients sick in the hospital from side effects. For veterinary oncology, the goal of chemotherapy is very different in that it is designed to control or eliminate the cancer while still providing a high quality of life for your pet. Chemotherapy drugs are not ordinarily used to cure cancer, but rather to control it and to slow down the progression of the disease. Many chemotherapy protocols involve a series of treatments, followed by a period of careful monitoring of remission. Chemotherapy may be continued as long as it is controlling the cancer, but only as long as quality of life is maintained.

A bio-hazard containment hood and personal protective apparel is used to prepare chemotherapy drugs for use at IndyVet. Patients are administered chemotherapy medication in a separate room to assure that no accidental exposure occurs to other IndyVet patients or personnel.

Targeted therapy is a form of chemotherapy that acts selectively against molecular targets expressed on the membrane of some tumors. Targeted therapy drugs interfere with tumor growth and progression. Targeted therapy is different from the non-specific destruction associated with traditional chemotherapy, which kills any rapidly dividing cell population in the body, whether cancerous or not.

Immunotherapy is a medical treatment that induces, enhances, or suppresses an immune response. The goal of immunotherapy in cancer treatment is to stimulate the patient’s immune system to reject and destroy tumor cells. Options for immunotherapy in veterinary oncology are currently very limited, but there is ongoing research that is very promising.

This type of treatment is focused on improving quality of life and not on curing cancer. Palliative and supportive care might include pain management and nutritional support which are available at IndyVet.
