The number of TILs obtained from each breast cancer subtype was not significantly different among subtypes (median, 2.0 × 105; range, 0.03–68.8 × 105 in HR+/HER2−; median, 3.6 × 105; range, 0.01–58.5 × 105 in HR+/HER2+; median, 4.8 × 105; range, 0.03–44.5 × 105 in HR−/HER2+; median, 3.3 × 105; range, 0.01–66.7 × 105 in TNBC; Figure 1C). Here, ERBB2 is linked to breast carcinoma.
