Stereotactic Body Radiation Therapy (SBRT) Re-irradiation to an Isolated Oligo-Recurrent Lymph Node with Direct Positron Emission Tomography/Computed Tomography Planning: A Case Report

Malignant recurrence always presents as a unique therapeutic challenge, more so in the setting of prior radiation. Where re-irradiation is considered, striking delicate balance between avoiding normal tissue toxicity while still delivering sufficient doses to ideal. For this purpose, with its capacity deliver ablative tumor target highly conformal manner, stereotactic body radiation therapy (SBRT) proves be an attractive option. What follows case locally advanced cervical cancer patient who underwent concurrent chemoradiotherapy but who, year after treatment, presented isolated pelvic lymph node within field. SBRT oligo-recurrence was subsequently performed.
