How is Body Radiosurgery Performed?
Stereotactic Body Radiosurgery at Radiosurgery New York is based upon years of experience by our physicians having treated thousands with fractionated stereotactic radiosurgery. Indeed tens of thousands stereotactic radiosurgery procedures have been performed by our group of physicians over many years. Talented, well-trained, well experienced personnel including physicians, physicists, dosimetrists, radiation therapists, nurses and other professionals are involved in our Body Radiosurgery program treatment. Also participating are radiologists, pathologists, medical oncologists as well as surgeons and statisticians to make a truly multi-disciplinary specialty Body Radiosurgery group at Radiosurgery New York. Techniques developed and refined by our experts reliably stabilize the body painlessly and non-invasively with an external frame of reference. This allows cancer localization for computerized treatment planning. Fine cut imaging techniques are performed with the patient in the stereotactic body frame to defer the tumor in relation to this external stereotactic frame of reference. Intensity Modulated Radiation Therapy (IMRT) helps shape the beam, but is only a part of our innovative approach at Radiosurgery New York.
The Concept of Body Radiosurgery.
The principle of Body Radiosurgery is precise non-invasive delivery of high radiation doses to the cancer while normal healthy surrounding tissues are, in general, spared the effects of the radiation beam. This is in marked contrast to standard radiation, which is much less able to protect normal tissues from radiation effects. Data collected with thousands of procedures being performed for primary and metastatic cancer treatment. Frequently these cancers were considered to be untreatable by other modalities or to have treatment approaches that were much less promising. Cancers treated include primary tumors and metastases to the following:
HEAD- including brain primary (glioblastomas, astrocytomas, meningiomas, acoustic neuromas, chordomas, glomus tumors) and metastatic (regardless of site of origin).
NECK- primary or lymph node involvement (many head and neck cancers respond well even despite extensive prior treatment) Each case, of course, is unique but a vast array of types of cancers including adenocarcinomas, squamous carcinomas, lung cancers, breast cancer, germ cell tumors, primary liver tumors, pancreas tumors, colon cancers, sarcomas, melanomas, renal cell, metastatic and primary head and neck cancers and others have been successfully treated and are included in ongoing data evaluation.
Our experts have treated cancers in patients in almost all ages - including children. While both extremes are unusual, we have the experience over many years of work. Tumor size has varied from very, very small 0.01cubic centimeter to very large - almost 6 liters - or 6000cc. Again, the extremes are unusual but give an idea of our diversity in experience over the years. Despite patients often, but not always, being heavily pre-treated with chemotherapy, surgery and radiation, they have responded to our treatment. Response, however, may not mean cure. Since each person and case is unique, prognosis must be discussed directly with your doctor. Of course, each patient ultimately decides what treatment is best suited to one's own unique concerns, needs and desires after fully being informed of all risks, benefits and alternatives. That is part of the Informed Consent process.
Prostate cancers have been a very special interest of our group. In fact, a whole information package is devoted to comparing our technique to surgery and other forms of radiation. To obtain this, call us at 212-CHOICES. Body Radiosurgery is frequently implemented after prostate seed implantation for maximum effectiveness of local treatment. Prostate seeds allow high doses to be delivered to the prostate while Body Radiosurgery consolidates the radiation to the prostate and the immediate surrounding tissues. We compare favorably to radical surgery or non-surgical radiation treatment with quality of life after treatment, in general. Our data is readily available in a separate publication and in our monthly open-to-the-public seminars. We are proud to compare our prostate cancer results to conformal radiation, standard radiation and radical prostatectomy performed at other major centers in America.
