Special Issue Information

Dear Colleagues,

Surgery is often used to attempt to cure patients whose tumors are localized within the gastrointestinal (GI) tract. However, tumor complexity and morbidity delaying a timely return to intended oncology treatment (RIOT) are important drawbacks with upfront resection and may be associated with worse outcomes.

Neoadjuvant therapy is an attractive concept for any GI malignancy that allows us to test tumor behavior and select the right patient for a major procedure, to downsize a previously borderline or unresectable tumor, to treat micro-metastatic disease early, and to allow organ preservation.

In 1974, Dr. Norman Nigro and colleagues at Wayne State University introduced neoadjuvant chemoradiotherapy prior to abdominoperineal resection for anal cancer. They initially published a series in Diseases of the Colon and Rectum of three patients with anal squamous cell carcinoma treated with combined chemotherapy and radiation. The first two patients underwent surgical resection, and complete pathological response was seen. The third patient declined surgery and was free of recurrence after 14 months of follow-up. This combination became known as the “Nigro Protocol”, and after further study, it became the new standard of care in anal cancer.

Since Dr. Nigro’s successful experiment, several trials have demonstrated the benefits of adding preoperative chemotherapy and/or radiotherapy in the treatment landscape.

This Special Issue aims to provide a comprehensive review of neoadjuvant therapies in GI malignancies, exploring the clinical application, current evidence, and treatment prospect with this approach in different tumors.

Pancreatic adenocarcinoma (PDAC) is the most common pancreatic cancer and is associated with poor prognosis, a high mortality rate, and a substantial number of healthy life years lost. Surgical resection is the primary treatment option for patients with resectable disease; however, only 10–20% of all patients with PDAC are eligible for resection at the time of diagnosis. In this context, neoadjuvant therapy has the potential to increase the number of patients who are eligible for resection, thereby improving the overall survival rate. For patients who undergo neoadjuvant therapy, computed tomography (CT) remains the primary imaging tool for assessing treatment response. Nevertheless, the interpretation of imaging findings in this context remains challenging, given the similarity between viable tumor and treatment-related changes following neoadjuvant therapy. In this review, following an overview of the various treatment options for PDAC according to its resectability status, we will describe the key challenges regarding CT-based evaluation of PDAC treatment response following neoadjuvant therapy, as well as summarize the literature on CT-based evaluation of PDAC treatment response, including the use of radiomics. Finally, we will outline key recommendations for the management of PDAC after neoadjuvant therapy, taking into consideration CT-based findings. Full article
