CyberKnife S7 is primarily a precision radiosurgery tool for solid tumors, but it plays a valuable role in blood cancer treatment in India for specific scenarios involving lymphoma and leukemia. While systemic therapies like chemotherapy and immunotherapy dominate blood cancer care, CyberKnife S7 offers targeted radiation for localized or resistant disease.
Understanding Lymphoma and Leukemia
Lymphoma arises from lymphocytes (Hodgkin or Non-Hodgkin), while leukemia originates in bone marrow. Both respond well to systemic treatment, but radiation remains relevant for:
Bulky or localized disease
Refractory/recurrent masses
Palliation of symptoms
When is CyberKnife S7 Recommended for Lymphoma?
CyberKnife S7 is indicated for lymphoma in these situations:
Refractory or recurrent nodal masses after chemotherapy, where precise radiation can achieve local control without widespread exposure.
Ocular or intraocular lymphoma, where CyberKnife radiosurgery has shown complete resolution with minimal toxicity—dry eye or cataract rare, vision often preserved.
CNS lymphoma for residual or recurrent lesions, as a boost after surgery or for small, well-defined tumors.
Palliative cases with painful or compressive lymphoma masses in brain, spine, or other sites.
Studies confirm excellent local control (e.g., 94% 5-year OS for pediatric lymphoma with SBRT), low toxicity, and feasibility for oligometastatic or limited relapse.
CyberKnife S7 for Leukemia: Limited but Strategic Role
Leukemia is systemic, so CyberKnife S7 is rarely primary but useful for:
Chloromas (myeloid sarcoma): Extramedullary leukemic masses in brain, spine, or soft tissue—CyberKnife provides high local control.
CNS prophylaxis or rescue for isolated CNS relapse in acute lymphoblastic leukemia (ALL).
Palliative radiation for painful bone lesions or bulky disease unresponsive to chemotherapy.
Pediatric series show SBRT/CyberKnife safe for oligometastatic leukemia sites, with high local control and low severe toxicity.
Benefits of CyberKnife S7 for Blood Cancers
Precision: Sub-millimeter accuracy spares bone marrow and healthy tissue, minimizing immunosuppression risk.
Non-invasive: Frameless, outpatient—ideal for fragile patients.
Hypofractionated: 1-5 sessions, quick completion.
Motion tracking: Perfect for mobile sites like lung/mediastinal lymphoma.
Procedure Overview
Imaging & Planning: MRI/CT/PET to define target; multidisciplinary review.
Fiducials (if needed) for tracking.
Sessions: 20-60 min each, robotic delivery with real-time adjustment.
Follow-up: Imaging at 3/6/12 months to assess response.
Side effects: Mild fatigue, skin irritation; severe rare (<5%).
