Efficacy of Laparoscopic Radical Resection Combined with Neoadjuvant Chemotherapy and Its Impact on Long-Term Prognosis of Patients with Colorectal Cancer

OBJECTIVE: The aim of the study is to examine the efficacy of laparoscopic radical resection of colorectal cancer combined with neoadjuvant chemotherapy and its impact on the overall prognosis of patients with colorectal cancer (CC). METHODS: A total of 80 CC patients hospitalized and treated at our hospital between November 2019 and June 2021 were selected at random as research subjects and divided equally into two groups: the surgical group (n = 40) and the combination group (n = 40). Patients in the surgical group were treated with laparoscopic radical resection, while patients in the combination group received laparoscopic radical resection combined with neoadjuvant chemotherapy. The two groups were compared in terms of surgery-related indicators, tumor markers (serum carcinoembryonic antigen (CEA), glycoprotein 199 (CA199), vascular endothelial growth factor (VEGF), and matrix metalloproteinase 9 (MMP9)), postoperative complications, and 1–3 years postoperative survival rate and recurrence rate. RESULTS: The surgical duration of the combination group was significantly shorter than the surgical group (P < 0.05). No significant differences were found in intraoperative blood loss, time to get out of bed, exhaust time, or hospital stay between the two groups (P < 0.05). In the combination group, serum tumor markers (carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA199), vascular endothelial growth factor (VEGF), and matrix metalloproteinase 9 (MMP9)) were markedly lower than those in the surgical group (P < 0.05). The combination group exhibited fewer postoperative complications than those in the operation group (P < 0.05). In the combination group, the 1–3 years postoperative survival rate was higher, while the 1–3 years postoperative recurrence rate was considerably lower than that in the surgical group (P < 0.05). CONCLUSION: CC patients benefit well from laparoscopic radical resection coupled with neoadjuvant chemotherapy. The approach is efficient in lowering blood tumor markers in patients and lowering the risk of surgery-related complications. It has the potential to enhance patients' long-term prognoses, allowing them to live longer and lower their chance of recurrence.
