RAB1A and neoplasm: Figure 1 shows MRI images of a patient with complete response, and Figure 2 shows PET/CT images. It shows that 39 patients underwent surgery, and 8 of them had pCR. A total of 9 patients had ypT0 (one of them was ypT0N1), 1 had ypT1, 6 had ypT2, 21 had ypT3, and 1 had ypT4. In addition, 27 patients had no pathologically involved lymph nodes (ypN0), 9 had ypN1, and 2 had ypN2. These findings and tumor regression grading distribution are summarized in Table 3.
