The administration of neoadjuvant chemoradiotherapy (nCRT) followed by total mesorrectal excision (TME) and selective use of adjuvant chemotherapy can still be considered the standard of care in locally advanced rectal cancer (LARC). However, avoiding sequelae of TME and entering a narrow follow-up program of watch and wait (W&W), in select cases that achieve a comparable clinical complete response (cCR) to nCRT, is now very attractive to both patients and clinicians. Many advances based on well-designed studies and long-term data coming from big multicenter cohorts have drawn some important conclusions and warnings regarding this strategy. In order to safely implement W&W, it is important consider proper selection of cases, best treatment options, surveillance strategy and the attitudes towards near complete responses or even tumor regrowth. The present review offers a comprehensive overview of W&W strategy from its origins to the most current literature, from a practical point of view focused on daily clinical practice, without losing sight of the most important future prospects in this area.

Background: Neoadjuvant combination immunotherapy is a potential treatment option for patients with proficient mismatch repair/microsatellite stable colorectal cancer. Preoperative screening via endoscopy and imaging examinations could help identify patients who may potentially achieve a complete response after neoadjuvant combination immunotherapy. This study aims to evaluate the diagnostic accuracy of endoscopic and imaging examinations in predicting pathological complete response after neoadjuvant combination immunotherapy.

Advancements in cancer care have significantly extended the life expectancy of rectal cancer patients and the impact of treatment-related toxicity on long-term quality of life has become a crucial factor in determining the most suitable type of neoadjuvant therapy, particularly for patients who are likely to undergo surgery. While radiotherapy has traditionally been regarded as the cornerstone for achieving improved local control in rectal cancer, it is accompanied by a range of associated complications, including bowel and bladder dysfunction, gonadal ablation, and Low Anterior Resection Syndrome. De-escalation of treatment is undoubtedly beneficial for many patients, and this approach should be tailored to consider their expectations while prioritizing patient care in decision-making.

Background: The watch-and-wait strategy provides an opportunity to pursue non-operative management in rectal cancer patients with clinical complete response after neoadjuvant therapy. The management of those with near complete response remains controversial.
Objective: We assessed the oncologic outcomes of patients managed by watch-and-wait versus total mesorectal excision according to clinical response to neoadjuvant therapy.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) has become the gold standard management for patients who present with common bile duct stone (CBDS). Although laparoscopic cholecystectomy is generally recommended for patients who have CBDS clearance, there is still a significant proportion of patients who are managed expectantly. Our study aimed to evaluate the outcomes of expectant management (EM) versus prophylactic cholecystectomy after initial endoscopic removal of CBDS.

Introduction: Extramedullary hematopoiesis (EMH) is very rarely described during sickle cell disease (SCD). Our aim was to describe six cases of EMH occurring in adult SCD patients and to conduct a literature review.
Methods: Retrospective, descriptive, and monocentric study, identifying all cases of EMH recorded in our cohort of adult SCD patients, up to April 2024.
