Figures & data
Figure 1 WHO ladder for cancer pain relief.
Figure 2 Radiotherapy planning images, illustrating how dose distributions around the planning target volume varies depending on the delivery technique used.
Notes: Images (A and C) are taken from the SYSTEMS study where parallel opposing pairs were employed. Images (B and D) are taken from SYSTEMS-2 and demonstrate the technical advances of IMRT in which multiple beams of radiotherapy of different shapes and intensity are delivered as the gantry moves around the patient, limiting dose deposition in surrounding organs.
Abbreviations: IMRT, intensity-modulated radiotherapy; SYTEMS, SYmptom Study of radioThErapy in MeSothelioma.

Figure 3 Image of radiotherapy planning from the SYSTEM-2 study, illustrating the typical dose distribution.
Notes: Clinical target volume is shown in pink and planning target volume in red. The radiotherapy field is targeted to the site of chest pain secondary to mesothelioma invading thoracic wall.
