Intrapatient and interpatient similarity by patient group
(A) Similarity matrix of TCR sequences between each of the two samples. The Bhattacharyya coefficient (0–1) was used to calculate the weighted similarity score; samples from the same patients are shown next to each other. R0, no residual disease; NACT-ER, excellent response to NACT; NACT-PR, poor response to NACT.
(B) Comparison of the similarity scores between different samples within the same patients across three groups.
