Efficacy of Capecitabine With Adjuvant Radiotherapy in Treatment of Early Stages Breast Cancer (Retrospective Study).
Study Overview
Detailed Description
Breast cancer is the most commonly diagnosed cancer among American women, In 2021 it is estimated that about 30%of newly diagnosed cancers in women will be breast cancer. As of January 2021, there are more than 3,8 million women with history of breast cancer in U.S.A including women currently being treated and those who finished treatment.
Death rates have been steady in women under 50years old since 2007,but have continued to drop in women over 50 years old .The overall death rate from breast cancer decreased by 1% per year from 2013 to 2018.these decreases are thought to be the result of treatment advances and earlier detection and screening.
About 43,600 women in U.S.A are expected to die in 2021 from Breast cancer. A woman's risk of breast cancer nearly doubles if she has a first degree relative who has been diagnosed with breast cancer .Less than 15% of women who get breast cancer have family member diagnosed with breast cancer. About 85% of breast cancer occur in women who have no family history of breast cancer ,these occurs due to genetic mutations that happen as results of aging process rather than inherited mutations. . [1]
The treatment of breast cancer includes the treatment of local disease with surgery, radiation therapy or both ,and systemic treatment with chemotherapy ,endocrine therapy ,biologic therapy or combination of these.[2]
After lumpectomy, whole breast irradiation is strongly recommended with or without boost to tumor bed for node positive (category 1 for those with positive nodes; category 2A for those with negative axillary nodes). This recommendation shows reduction in 10 -year risk of recurrence in those who received whole breast irradiation versus those who did not. In addition significant reduction in 15-year risk of breast cancer death was also observed. [3] Radiotherapy after mastectomy and Axillary lymph node dissection in (node positive disease) reduced both recurrence and breast cancer mortality in women with 1-3 positive lymph nodes even when systemic therapy was administered. [4] In node negative disease and tumor less than 5 cm and clear margin >1mm, post mastectomy radiation therapy is not recommended.
Primary radiotherapy has been used for local control of breast tumors in variety of situations. Excellent local control was obtained by Chargari et al with radiation alone in early stage tumors with loco regional control at 7 years of 95,8%. [5] Certain chemotherapeutic agents are known as radio-sensitizers, allowing for enhanced therapeutic ratio and improved tumor control when given concurrently with radiotherapy .concurrent chemo -radiotherapy has been used at multiple disease sites , with gains in local control, disease free survival ,and overall survival over radiation alone.[6] Combining adjuvant radiotherapy with capecitabine appears to be safe and feasible for chemotherapy resistant breast cancer patient with stage I-III who has residual disease in form of improve local and distant disease control [7].
