Sterotactic Ablative Radiotherapy (SABR) pronounced “SABER” involves the administration of very focused radiation doses to an isolated tumor or tumors within the body, with the goal of complete tumor cell kill in the treated area. SBRT is an image-based treatment using a high dose of radiotherapy with pinpoint accuracy in three to five sessions.
Our new SABR systems image, localize and shape radiation for small to moderate-sized tumors. SBRT also uses highly enhanced CT image guidance preceding each treatment to provide optimal treatment accuracy. In some cases, SABR reduces treatment duration from thirty visits to as few as one to five.

Breast Intraoperative Radiation Therapy (IORT) delivers a high dose of radiation focused on the remaining breast tissue surrounding a tumor that has been removed after a lumpectomy surgery while the patient is still in the operating room. This thereby limits the exposure of distant breast tissue to radiation. IORT is also able to shield underlying organs like the heart and lungs from radiation. IORT reduces the number of radiation days/weeks that are needed to treat breast cancer.

Tomotherapy has revolutionized the delivery of radiation in patients with cancer. It is the most precise, accurate and advanced, and sophisticated radiation treatment machine of its kind. Tomotherapy uses Imaged Guided Intensity Modulated Radiation Therapy to shape radiation more precisely than was ever possible before. The makers of Tomotherapy are so confident in the accuracy of technology that they have challenged all other radiation treatment machines to try to beat the accuracy of their radiation treatments. Tomotherapy is EXCLUSIVELY available at our office at Alta Bates Summit Medical Center in Oakland, CA and we proudly serve the entire San Francisco Bay Area with this amazing technological innovation.
Superficial Radiation Therapy (SRT) for Skin Cancers is a treatment option for certain patients with skin cancers (Squamous Cell Carcinoma, Basal Cell Carcinoma, Melanoma and Kaposi’s sarcoma) The procedure is painless, non-invasive and less expensive than traditional treatments.
It uses a low energy radiation beam (X-ray) which only penetrates the top surface layer of the skin, avoiding deep tissue damage which minimizes scarring, particularly around the face.
For High-Dose Rate (HDR) Brachytherapy, thin catheters or an applicator is placed in or around a tumor. These are then connected to a machine called an HDR afterloader. This machine contains a single highly radioactive iridium source at the end of a wire. The source is pushed into each of the catheters one by one under computer control. Radiation is then delivered precisely to the tumor. HDR Brachytherapy is used for prostate cancer, endometrial cancer, cervical cancer and skin cancers.

Cyberknife is a new treatment that is being used to treat localized tumors. This system uses a miniature radiation machine and a robotic arm that moves around the patient while delivering small doses of radiation from hundreds of directions. During treatment a computer analyzes hundreds of images and adjusts for slight movements by the patient. Only the tumor receives the high doses of radiation and healthy tissue is spared.
Breast Inspiratory Breath Hold Radiotherapy (IBH)
Traditionally radiation includes a small portion of the heart in the radiation field when treating left sided breast cancers. The use of a simple inspiratory maneuver – taking a deep breath and holding it for a few seconds is called Breast Inspiratory Breath Hold Radiothearpy (IBH). For selected patients, this significantly decreases the heart and lung volume that gets radiation.
Image Guided Intensity Modulated Radiation Therapy (IGIMRT, IG-IMRT) represents a significant technological advance and a new paradigm for the radiotherapeutic management of cancer. IMRT is capable of sparing sensitive structures of a high-dose radiation, by shaping the radiation even if only several millimeters away from the tumor. Image Guided Intensity Modulated Radiation Therapy (IGIMRT, IG-IMRT), the latest advancement consists of IMRT combined with Image Guidance. A scan is performed just prior to treatment to adjust for positional or anatomical changes. This allows for the most accurate and precise radiation treatments possible.
For Image Guided Radiation Therapy (IGRT), a scan is performed just prior to treatment to adjust for positional or anatomical changes. When you combine this with Intensity Modulated Radiation Therapy (IMRT) you get the most accurate and precise radiation treatments possible.

SAVI® brachytherapy combines the skin-sparing dosimetry of interstitial brachytherapy with the single-entry ease of balloon brachytherapy. The applicator uses an expandable bundle of catheters placed in the lumpectomy cavity through a single incision. As with the multicatheter and balloon brachytherapy options, the typical treatment schedule is twice daily for 5 days. This hybrid approach is designed to allow more flexible treatment planning, enable better shaping and control of the radiation dose and reduce radiation exposure to the skin and chest wall. SAVI is being evaluated in a separate clinical trial.
The Contura® balloon allows the doctor to fill the empty space left by the lumpectomy. Contura allows refined placement of the radiation source and targets the dose only where needed, sparing healthy breast tissue. The design can offered to some patients who are not candidates for other balloon devices.
MammoSite® brachytherapy uses a single catheter centered inside a balloon and is delivered in 10 treatments over 5 days, with treatments separated by at least 6 hours. MammoSite and interstitial brachytherapy are being compared with whole-breast irradiation in a Phase III clinical study(NSABP B-39/RTOG 0413 trial).
These options offe 5-day treatment brachytherapy alternatives known as accelerated partial breast irradiation (APBI). While conventional radiation therapy after breast-conserving surgery is delivered to the whole breast over a period of 7 weeks, radiation therapy delivered over a much shorter time period and only to the involved portion of the breast. We have pioneered APBI and currently offer patients the opportunity to participate in clinical trials evaluating 5‑day partial breast irradiation. We also treat selected women with APBI off-trial. The treatment options include APBI using balloon devices or catheters.
Prostate patients may also be treated using brachytherapy in the form of seed implants.
Radiation therapy plays a strong role in breast cancer treatment – from the earliest stage to the latest stage of the disease. Many patients with breast cancer will benefit from radiation therapy, either as curative or adjuvant therapy, or as a palliative treatment. These patients are typically treated with 3D conformal radiation therapy over a course of seven weeks. Other patients may be candidates for brachytherapy. The term brachytherapy is derived from a Greek word meaning “from a short distance,” and describes the practice of treating cancer by placing radioactive material directly into the cancer or immediately around it.
Sterotactic Radiosurgery (SRS)
Stereotactic radiosurgery (Tomotherapy, Cyperknife or Gamma Knife) uses gamma rays or a linear accelerator, to treat certain kinds of brain tumors and some malformations in the brain’s blood vessels. The treatments are painless and bloodless and, unlike conventional brain surgery, there is no danger of infection. These systems use a linear accelerator to deliver the radiation in arcing paths around the patient’s head.
Our prostate cancer patients are treated using external beam radiation therapy with (IMRT) Intensity-Modulated Eadiation Therapy (IMRT) and (IGRT) Image Guided Radiation Therapy (IGRT). Image guidance ensures that the patient is positioned to accommodate normal daily variation of internal organs.
Stereotactic Body Radiation Therapy (SBRT)
SBRT (Stereotactic Body Radiotherapy) is a method of radiosurgery recently developed for Lung, GI and other tumors. It uses high doses of radiation delivered in fewer fractions than in conventional radiation therapy. An advanced treatment planning system permits precise targeting from many angles. As with other advances in radiation treatment, it allows high doses of radiation to be delivered to tumor tissue while reducing radiation damage to healthy tissue.
Intensity Modulated Radiation Therapy (IMRT) is a type of conformal therapy that shapes high doses of radiation to the targeted tumor while restricting the dose to surrounding tissues. In the past, conformal radiation therapy has been limited to the use of radiation beams of uniformed intensity. In IMRT, the intensity of radiation beams is varied across the treatment field. This is accomplished through the use of multiple small beams with varied intensity instead of a single, large beam. Physicians “cross fire” the tumor with these small beams to deliver high-dose radiation to the targeted site while minimizing damage to the surrounding areas.
IMRT is particularly useful in cases where tumors are not well separated from vital organs. If a tumor is wrapped around a nearby organ, uniform intensity beams often cannot safely target radiation without the risk of damage to organ tissue. In these circumstances, adding intensity modulation allows for high-dose treatment of the tumor while protecting the organ from harmful radiation.
Three-Dimensional Conformal Radiation Therapy (3DCRT) uses the most advanced technology to tailor radiation to fit the shape of the treatment area by using small leaves (a multileaf collimator (MLC)) and a varying number of radiation beams. When the treatment volume conforms to the shape of the tumor, the radiation dose to surrounding healthy tissues is reduced, allowing a higher dose of radiation to be delivered to the tumor. Because the radiation beams are precisely focused, nearby normal tissue is spared. 3DCRT is delivered using a linear accelerator while the patient is positioned on a treatment table. This technique is being used to treat breast cancer, prostate cancer, lung cancer, certain brain tumors and other other cancers.
11/12/2011Dr. Sachdeva is the sweetest guy imaginable, and an extremely competent caring radiation oncologist. Spent lots of time explaining things and answering questions. The whole team is kind, efficient, always on time, very responsive.
From the first I felt very comfortable in the care of this physician, and his radiation support team is top notch. They are caring, upbeat, sensitive professionals. I observed, not just how they handled my medical care, but also the care of patients who were critically ill and frightened. Doctor Sachdeva and his medical team are right up there with the best.
Thanks to all of you!
Well I can’t say enough good things about Dr. Sachdeva and the care I received. All questions, concerns or care were answered and always with encouragment. What a pleasure to have a carring physician. If you’re in need of a good Radiation Oncology you don’t need to look futher.
Thanks for giving me back my life.
The only thing I can add is all of you have a special place in my heart forever. Thank you so much. Happy 2010 to everyone.
It was a long road to recovery for my mom with her cancer treatment. Dr. Sachdeva made a big difference and we will never forget it.
Without a doubt, visiting a Radiology Oncologist can be an intimidating and frightening experience, but with Dr. Sachdeva, it was totally the opposite. The patience and care that he offered was endless. He was readily available for any and all concerns that we had. Every step of the way, everything was explained in a very clear, comprehensible manner.
The team of nurses and technicians all work together in a manner that exudes the confidence and upbeat attitude that a patient needs to get through one of the most difficult times in a patient’s life. I truly believe that my mom wouldn’t have been able to complete her radiation treatment, had it not been for the unique relationships she formed with each and every person in Dr. Sachdeva’s office.
