New Patient Testimonial

We just received a testimonial from one of our prostate cancer patients, and would like to share his comments with you all:

“The staff at the Pasadena CyberKnife Center was very patient and accommodating.  They worked very hard to make sure that the entire treatment process went as smoothly as possible.  They addressed all my concerns and issues promptly and fully.    They also made patient comfort a high priority in their center and I was comfortable the entire time.  The treatment itself was not stressful and the side effects is very minimal.  Thank you for everything!”


Dear J:

Thank you so much for the wonderful testimonial you gave us.  We wish you all the best!

From Team PCC =)


Lung Metastases Case Study

Here’s another case study we would like to share:

Amy (name has been changed to protect patient’s privacy) is a 48-year-old female diagnosed with bone sarcoma and underwent below-knee amputation of right leg 3 years ago.  Unfortunately, she developed multiple metastases in both lungs a year later.  She decided to undergo two aggressive surgeries and more than 10 lesions were removed from each lung.  She also received chemotherapy following the surgeries.

Earlier this year, Amy was found to have 2 recurrent lung metastases which are located in areas of the lung that are difficult to resect.  Her lung function has greatly decreased in the past 2 years due to the surgeries she underwent.  As a result, she was skeptical and went in search for other options.  One of her friends, who was recently treated at our center, advised her to contact us.  After consulting with Dr. Albert Mak and her medical oncologist, it was determined that she was a good candidate for the CyberKnife radiosurgery treatment.  Amy was still very nervous about this radiosurgical procedure we recommended because she did not want to undergo further surgery.  Although the name CyberKnife suggests scalpels, operating rooms and recovery time, it actually involves no incisions, no anesthesiano pain and no hospital stay.  The CyberKnife is indeed a knifeless outpatient procedure.  After careful consideration and weighing her options, Amy decided rather quickly to have the CyberKnife treatment.

Due to the size and location of her lesions, we recommended two separate courses of treatment.  During the first course of treatment, we focused on treating the larger tumor.  The first course was only 3 days, and each treatment took about 45 minutes.  The CyberKnife treatment is a painless and non-invasive procedure which was a big thumbs up for Amy.  Unlikely other radiosurgical devices, no immobilization device is needed for CyberKnife.  The robot continuously tracked Amy’s lung lesions and adjusted for movement.  As a result of this unique tracking capability only available with the CyberKnife system, Amy did not have to hold her breath during treatment and was able to breathe normally and relax comfortably.

Amy tolerated the short course of 3-day treatment very well.  She also underwent chemotherapy during the CyberKnife treatment.  It has been a month since her first treatment, and we are happy to report that the follow-up CT scan shows that the tumor was reduced by half.  She feels very optimistic and hopeful for the future, and will start her second course of treatment next week.

CyberKnife for Sarcoma

Today, we would like to share with you a very unique case study – Sarcoma.  Sarcoma is a cancer that develops from soft tissue or bone, whereas carcinoma – the most common type of cancer – develops from the cells that cover the inner or outer surfaces of the body.  Sarcomas are quite rare as there are only approximately 15,000 new cases per year in the U.S.

This case study features a 68-year-old man with a history of nasopharyngeal cancer named Mr. Wu.  He had been cancer-free since he received radiation therapy in Taiwan in 1991.  In early 2010, he was found to have a recurrent mass in the nasal cavity, and the biopsy results confirmed a diagnosis of Sarcoma.  This newly diagnosed sarcoma is different from his original nasopharyngeal carcinoma.  It is probably a new tumor caused by his previous radiation treatment (we call it a “radiation-induced sarcoma”).  Radiation-induced sarcoma is rare and it usually takes 15-20 years for the secondary tumor to develop.

Mr. Wu’s new sarcoma had grown since last year and was causing profuse nose bleeding and hearing loss in both ears.  He decided to seek medical care from the world-renowned University of Texas M.D. Anderson Cancer Center in Houston, Texas, where our Medical Director, Dr. Albert Mak, completed his residency training.  Mr. Wu had an MRI upon arrival at M.D. Anderson Cancer Center.  The results showed a large tumor in the nasopharynx and nasal cavity measuring about 3 inches.  In addition, the tumor was reaching the bone of the skull.  Based on the results, the physician recommended chemotherapy which Mr. Wu refused due to personal reasons.

Fortunately, Mr. Wu’s daughter, who had learned of our center, suggested he contact our center for second opinion.  While still in Houston, Mr. Wu emailed us his clinical notes and MRI reports.  After reviewing his records, Dr. Mak believed that the CyberKnife treatment could help him.  Mr. Wu flew to Los Angeles the next day to see Dr. Mak because the CyberKnife treatment is not currently available at M.D. Anderson Cancer Center.  Further examination and consultation at our center confirmed that Mr. Wu was indeed a perfect candidate for CyberKnife.

Treatment and Result:

We treated Mr. Wu with CyberKnife for 5 days from 01/26/11 to 02/04/11.  He tolerated the treatment very well.  When he was seen two weeks later, he reported that his nose bleeding had stopped and he could breathe much better.  He had another MRI on 03/18/11, and the results revealed a complete disappearance of the tumor.  PET/CT done 3 months after treatment continued to show no evidence of disease.


Sarcoma has been known to be resistant to conventional radiation.  On the other hand, CyberKnife is effective in treating sarcoma because it can deliver a very high dose of radiation at the target without causing complication or side effects.  Furthermore, the treatment is very precise and painless. The entire course of treatment only takes 5 days and is done on an outpatient basis. Patients can return to their normal activity right after treatment as there is no recovery time required.

If you have questions regarding CyberKnife for sarcoma, please feel free to contact our center.
