What's the difference between 15 and 25 postoperative radiotherapy for breast cancer?

Breast cancer is one of the most common female tumors, and the incidence of breast cancer in China is on the rise, and the age is younger than in the West.
most breast cancers require comprehensive treatment such as radiotherapy, chemotherapy, endocrine therapy or targeted therapy after surgery.
after early breast cancer preservation surgery and improved treatment with lymph node metastasis, patients need to be treated with breast, chest wall or regional lymph nodes.
postoperative radiotherapy not only reduces the local recurrence rate of breast cancer, but also contributes to improving survival rate.
patients will ask, breast cancer after-surgery radiotherapy program, some only do 15 times, some do 25 times, what is the difference between the two? What is Large Split Therapy? Traditional radiotherapy for breast cancer uses conventional segmentation, i.e. 2.0Gy per week, 5 times a week, a total dose of 50Gy, requiring 25 (5 weeks) of treatment to complete.
long history of conventional segmented radiotherapy for breast cancer, but in recent years it has been gradually challenged, and more and more clinical applications of large-segmented radiotherapy mode have been used.
large-segmented radiotherapy refers to a single dose of 2.6-3.2Gy, the number of exposures reduced to 13-15 times (within 3 weeks), the total dose of 39.0-43.5Gy.
2016 U.S. NCCN guidelines recommend that breast cancer be treated with either conventional split radiotherapy or large segmentation.
The Breast Cancer Division Radiotherapy Program shows the benefits to patients: shorter radiotherapy cycles, fewer visits to or from hospitals, reduced time, effort, and energy costs, and patients are more reservist.
effect of the great division therapy? Is there a difference in the efficacy of large-segmented radiotherapy compared to conventional segmentation? Long-term clinical studies have confirmed that breast cancer large division radiotherapy not only ensures efficacy - without reducing local recurrence and total survival rate - but also does not increase, or even reduce, side effects.
The results of the 10-year follow-up study in the United Kingdom showed that the local recurrence rate of large division after early breast cancer preservation surgery was 4.3%, and the general division was 5.9% .
side effects of the treatment of large splits? In the side reaction, large-segment radiotherapy has some advantages over conventional segmentation.
clinically defined the radiation side reaction of level 3 as a severe side reaction.
side effects of radiation for breast cancer include skin collapse and breast edema.
, whether breast-protected or improved acute reaction after treatment, the large division was 0-3%, and the conventional division was 4.34-8%, showing the advantages of large division.
follow-up for 10 years to observe the satisfaction of breast-protected patients with beauty effects, there was no significant difference between large division and conventional division, the former 69.8 percent, the latter 71.3 percent.
, such as the risk of death from heart disease after 15 years of radiotherapy, was comparable to large division, at 4.8% and 4.2%, respectively.
summary: breast cancer, whether breast cancer or non-dairy improvement treatment, can be used large-segment radiotherapy.
, the efficacy of breast cancer large division radiotherapy is comparable to conventional split radiotherapy, the treatment cycle is shorter, providing convenience for patients, but also to reduce the trend of acute side reactions.
the individual condition of the patient will be fully evaluated before a specific treatment plan is developed.
