Four months later, the pulmonary nodules had grown significantly large (one measured 6x10 cm) as well as a lymph node on the gastrohepatic ligament (Figure 1). At this time, we began palliative radiation treatment of the pulmonary metastasis with 40 Gy in ten fractions over a thirteen day time period (Figure 1). Measurements of the treated metastatic right lung mass pre-treatment resulted in a maximal left-right (LR) diameter of 9.1 cm, a maximal anterior-posterior (AP) diameter of 10.6 cm, a maximal superior-inferior (SI) diameter of 14.0 cm, and a volume of 538 cm3 (Figure 1).

At four months post-treatment, the mass measured LR diameter 7.6 cm, AP diameter 5.6 cm, SI diameter 9.1 cm, and volume 100 cm3 (Figure 2), and at six months post-treatment, the mass measured LR diameter 7.6 cm, AP diameter 5.8 cm, SI diameter 8.5 cm, and volume 75.8 cm3 (Figure 3). Unfortunately the patient continued to develop pulmonary metastases (Figures 2 and 3). The response in the treated metastases had been durable during the 6 months of follow-up (Figures 2 and 3).
