The incidence of pulmonary polymetastases (PPM) and synchronous multiple primary lung cancers (SMPLC) is on the rise due to improvements in computed tomography (CT) scanning and increasing use of positron emission tomography scanning and other diagnostic modalities. I plan to evaluate different approaches and methods in the treatment of PPM and SMPLC utilizing dosimetric evaluation parameters. Currently, resection is still the primary and most effective method of treatment for these tumors, yet in cases when lesions are inoperable Stereotactic Body Radiotherapy is utilized. Stereotactic radiotherapy is, in fact developing into a standard of care for inoperable, unresectable tumors. We have seen a rise in patients that present with PPM and SMPLC with some patients presenting with synchronous lung nodules in the ipsilateral or contralateral lobe or metasynchronous disease. In some of the incidences the PMP and SMPLC can present in the same plane. In these cases, patients may receive multiple courses of lung SBRT or a single course of SBRT depending on different parameters determined by the Radiation Oncologist. Unfortunately, the toxicity of such treatment is currently unknown since there is no data to determine endpoints. With this in mind, there are very extensive team discussions and planning forums that take place to visualize what the best approach should entail concerning treating these specialized patients.
1. How AAMC approaches patients with PMP and SMPLC;
2. What planning approaches were successful for AAMC and how it could be implemented in your department;
3. Modalities present different pitfalls and successes. It’s important we learn what each modality provides.
