Study Description

Brief Summary: This study analyzed the efficacy differences between neoadjuvant therapy and direct surgical treatment in patients with locally advanced rectal cancer in the real world. The aim was to evaluate the impact of neoadjuvant therapy on overall survival, disease-free survival, and local recurrence-free survival in patients with locally advanced rectal cancer, explore the population benefiting most from neoadjuvant therapy, and provide evidence-based medicine for the benefits of neoadjuvant therapy in patients with colorectal cancer in the real world.

Detailed Description: Colorectal cancer ranks third in terms of global incidence (10.2%) and second in terms of mortality (9.2%) among malignant tumors, with rectal cancer accounting for one-third of cases. The standard treatment regimen for locally advanced rectal cancer (LARC), neoadjuvant chemotherapy (NACT) combined with total mesorectal excision (TME), has been shown to better control local disease, reduce local recurrence rates, but does not improve overall survival. In recent years, with the continuous improvement of surgical techniques, surgical treatment has also achieved better local control effects for locally advanced rectal cancer. However, the efficacy of neoadjuvant therapy varies greatly in different studies. For locally advanced rectal cancer, a prospective clinical study published in the New England Journal of Medicine in 2004 compared the efficacy differences between preoperative neoadjuvant chemoradiotherapy (NCRT) and postoperative chemoradiotherapy. The study demonstrated that compared to postoperative chemoradiotherapy, preoperative NCRT combined with total mesorectal excision could better control the local disease, reduce the toxicity of chemoradiotherapy, but did not help prolong overall survival. However, due to issues such as increased postoperative complications associated with neoadjuvant radiotherapy, some rectal cancer patients refuse neoadjuvant radiotherapy. Therefore, a significant amount of research has also been devoted to proving the efficacy of neoadjuvant chemotherapy alone. Additionally, neoadjuvant therapy can also increase the rate of sphincter preservation for low rectal cancer. However, there is still controversy over whether neoadjuvant therapy can bring survival benefits to rectal cancer patients. How to reduce overtreatment caused by neoadjuvant therapy and related toxic side effects is also a current research hotspot. This study analyzed the efficacy differences between neoadjuvant therapy and direct surgical treatment in patients with locally high-risk rectal cancer in the real world, aiming to evaluate the impact of neoadjuvant therapy on overall survival, disease-free survival, and local recurrence-free survival in patients with locally high-risk rectal cancer, explore the high-benefit population of neoadjuvant therapy, and provide evidence-based medicine evidence for the benefits of neoadjuvant therapy in real-world rectal cancer patients.
