Studies have shown that a substantial number of patients treated with mastectomy alone experience a local recurrence of cancer. Radiotherapy aims to mitigate this risk, ensuring a better prognosis for patients.
Reduction of Local Recurrence
The most compelling reason for administering radiotherapy after mastectomy is the reduction in local recurrence of breast cancer. Numerous clinical trials have consistently demonstrated that radiotherapy significantly decreases the rate of local recurrence, especially in patients with certain risk factors. These factors include larger tumor size, positive lymph nodes, and high histological grade.
According to the National Comprehensive Cancer Network (NCCN), the addition of radiotherapy post-mastectomy can reduce local recurrence by about 30-50%. This statistic underscores the need for a thorough evaluation of individual patient cases. The goal is to balance the potential benefits against possible complications resulting from treatment.
Impact on Survival Rates
Another notable aspect of post mastectomy radiotherapy is its positive effect on survival rates. Historical data indicate that the long-term survival of patients treated with radiotherapy after mastectomy is superior to those who undergo surgery alone. The European Organisation for Research and Treatment of Cancer (EORTC) emphasized that the risk of breast cancer mortality decreases when radiotherapy is included in the treatment plan.
Recent studies suggest that the survival advantage may be more pronounced in high-risk groups. For example, women with multiple positive lymph nodes tend to benefit significantly from receiving radiotherapy. This reinforces the necessity of clinical guidelines that identify which patients are most likely to gain from post mastectomy radiotherapy.
Patient Selection Criteria
Not every patient may require radiotherapy after mastectomy; hence, a careful patient selection process is crucial. Factors influencing the decision to administer radiotherapy include tumor characteristics, patient age, and overall health status.
- Tumor Characteristics
- Patient Age
- General Health
