Complete pathological response in locally advanced non-small-cell lung cancer patient: A case report

Figure 1 Positron emission tomography/computed tomography staging before the start of chemoradiotherapy treatment. A: The orange arrow indicates the localization of the involved mediastinal lymph node in station 2R; B: The orange arrow indicates the localization of the involved mediastinal lymph nodes in stations 7L and 4L; C: The orange arrow indicates the localization of the primary tumor with mediastinal infiltration. Radiological staging was cT4 cN3 cM0.

Figure 2 Dose distribution of the patient radiotherapy plan on computed tomography. The color legend dose-volume histograms in the column on the right illustrates the dose distribution. Prescription dose was 30 Gy/5 daily fractions with a heterogeneous dose escalation of up to 40 Gy inside the primary tumor to simulate brachytherapy dose distribution. Prescription dose was 25 Gy/5 daily fractions with a heterogeneous dose escalation of up to 37.5 Gy inside the nodal tumor. The different colors show the following isodoses: red, 30 Gy; deep blue, 40 Gy; aqua, 37.5 Gy; light blue, 12.5 Gy; green, 25 Gy; pink, 20 Gy; light blue, 12.5 Gy; yellow, 5 Gy.
