    Roche remains committed to tracking science to better understand cancer, including which patients may benefit from immunotherapy.
    Tecentriq has proven its transformative role in the field of high medical needs, and is the first drug of its kind to be approved to treat certain types of cancer that are particularly difficult to treat.



    Tecentriq's extensive development projects include a number of ongoing and planned Phase 3 studies, covering lung cancer, genitourinary tract cancer, skin cancer, breast cancer, gastrointestinal cancer, gynecological cancer, head and neck cancer and other cancer types.
    This includes studies evaluating Tecentriq alone or in combination with other drugs, as well as studies in metastatic, adjuvant therapy, and neoadjuvant therapy.



    Breast cancer is the most common type of cancer in women, with more than 2 million cases diagnosed globally each year.
    TNBC accounts for about 15%.
    Compared with other types, TNBC is more common in women under 50.
    TNBC specifically refers to breast cancer with negative expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2), which progresses rapidly and has a very poor prognosis, 5 years The survival rate is less than 15%.
    TNBC is ineffective against hormone therapy and HER2 targeted therapy (such as Herceptin), and treatment options are very limited, mainly relying on chemotherapy.
    Metastatic TNBC is one of the most aggressive and difficult to treat breast cancers.
    Compared with other subtypes of breast cancer, metastatic TNBC progresses rapidly and has a shorter survival time.


    For the past 30 years, Roche has been advancing breast cancer research, with the goal of helping as many breast cancer patients as possible.
    The company's targeted drugs Herceptin, Perjeta, Phesgo, Kadcyla, Tecentriq are continuing to change the treatment pattern of early and late HER2-positive breast cancer and TNBC.
    Through clinical development projects, Roche hopes to bring new treatment combinations to breast cancer patients and ultimately improve the prognosis.
