what would be treatment options for 63yr old male who was diagnosed with Ca stomach (T3N1M0) in Aug 08 after which distal gastrectomy was done - after this he received 6 cycles of chemo - 2 months after this he underwent adjuvant radiation by IGRT technique (took approx 5 wks to complete 25 sessions of 4500cGy doses) - 1 month after radiation a pet ct showed that there is a celiac lymph node (bifurcation) which is malignant - is cyberknife a possibility considering that he has already had radiation - would this make cyberknife treatment too toxic for his body?
Conceptually, CyberKnife is closer to surgery rather than to radiotherapy. It uses a robotic arm to deliver high doses to energy to ablate a target tissue. This energy is in the for of radiation. Cyberknife has sub-centimeter precision, thus normal tissue is spared. This limits the side effects.
You may be a reasonable candidate for CyberKnife. However, the final decision is only possible after a physical examination and review of reports.
All the best, and God Bless!
