论文摘要
肿瘤浸润淋巴细胞（TIL）的定量已被证明是乳腺癌患者预后的独立预测因子。通常，病理学家对含有tils的基质区域的比例进行了估计，以获得TILS评分。乳腺癌（Tiger）挑战中肿瘤浸润淋巴细胞旨在评估计算机生成的TILS评分的预后意义，以预测作为COX比例风险模型的一部分的存活率。在这一挑战中，作为Tiager团队，我们已经开发了一种算法，以将肿瘤与基质肿瘤与基质，然后将肿瘤散装区域用于TILS检测。最后，我们使用这些输出来生成每种情况的TILS分数。在初步测试中，我们的方法达到了肿瘤 - 细胞瘤的加权骰子得分为0.791，而淋巴细胞检测的FROC得分为0.572。为了预测存活率，我们的模型达到了0.719的C-指数。这些结果在老虎挑战的初步测试排行榜中获得了第一名。
The quantification of tumor-infiltrating lymphocytes (TILs) has been shown to be an independent predictor for prognosis of breast cancer patients. Typically, pathologists give an estimate of the proportion of the stromal region that contains TILs to obtain a TILs score. The Tumor InfiltratinG lymphocytes in breast cancER (TiGER) challenge, aims to assess the prognostic significance of computer-generated TILs scores for predicting survival as part of a Cox proportional hazards model. For this challenge, as the TIAger team, we have developed an algorithm to first segment tumor vs. stroma, before localising the tumor bulk region for TILs detection. Finally, we use these outputs to generate a TILs score for each case. On preliminary testing, our approach achieved a tumor-stroma weighted Dice score of 0.791 and a FROC score of 0.572 for lymphocytic detection. For predicting survival, our model achieved a C-index of 0.719. These results achieved first place across the preliminary testing leaderboards of the TiGER challenge.
