Su Lien-ying points out that in the past it was usually a surgeon who was responsible for the entire process of cancer treatment. Now that there are oncologists, some surgeons feel that their "turf" is being "invaded," and they are unwilling to turn over chemotherapy to the oncologists. It is not uncommon to see surgeons "crossing departmental boundaries" to take charge of chemotherapy for their patients.
蘇連瓔指出，過去外科醫師包辦所有癌症治療，現在有腫瘤內科專科醫師，有些外科醫師覺得專業受到「衝擊」、「挑戰」，不願意將化療交給腫瘤內科醫師處理，因此，各醫院仍不乏外科醫師「跨科」幫病人做化療的情形。
