The ‘Watch and Wait’ Strategy in Rectal Cancer: Weighing the Pros and Cons

Background: Treatment for locally advanced rectal cancer has evolved significantly, particularly with the advent of neoadjuvant chemoradiotherapy (nCRT). The “watch and wait” (W&W) approach, designed to avoid surgery for patients with a complete clinical response (cCR) following nCRT, has emerged as an alternative to traditional surgical interventions, particularly total mesorectal excision (TME). However, its long-term efficacy and safety remain debated. Methods: This article reviews the W&W strategy, focusing on its definition, clinical outcomes, and both its advantages and disadvantages. We analyze the pros of W&W, including improved quality of life, organ preservation, and comparable disease-free survival rates. We also examine the cons, such as higher risks of recurrence, metastasis, and logistical challenges related to surveillance. Results: The W&W approach has demonstrated promising results in preserving rectal function and improving patient quality of life. However, studies show an increased local recurrence rate compared to TME, with a higher likelihood of distant metastasis in cases of recurrence. Additionally, the strategy requires intense follow-up, posing a challenge for patient compliance and healthcare resource management. Psychological stress related to the uncertainty of treatment further complicates the approach. Conclusions: While the W&W strategy offers substantial benefits in terms of organ preservation and quality of life, it presents significant risks, including higher recurrence rates, logistical complications, and psychological burdens on patients.
