Background: The management of unresectable locally advanced colon cancer (LACC) remains controversial, as resection is not feasible. The goal of this study was to evaluate the treatment outcomes and toxicity of neoadjuvant chemoradiotherapy (NACRT) followed with surgery and adjuvant chemotherapy in patients with unresectable radically LACC.
Methods: We included patients who were diagnosed at our institution, 2010-2018. The neoadjuvant regimen consisted of radiotherapy and capecitabine/ 5-fluorouracil-based chemotherapy.
Results: One hundred patients were identified. The median follow-up time was 32 months. The R0 resection rate, adjusted nonmultivisceral resection rate and bladder preservation rate were 83.0, 43.0 and 83.3%, respectively. The pCR and clinical-downstaging rates were 18, and 81.0%%, respectively. The 3-year PFS and OS rates for all patients were 68.6 and 82.1%, respectively. Seventeen patients developed grade 3-4 myelosuppression, which was the most common adverse event observed after NACRT. Tumor perforation occurred in 3 patients during NACRT. The incidence of grade 3-4 surgery-related complications was 7.0%. Postoperative anastomotic leakage was observed in 3 patients.
Conclusions: NACRT followed by surgery was feasible and safe for selected patients with LACC, and can be used as a conversion treatment to achieve satisfactory downstaging, long-term survival and quality of life, with acceptable toxicities.

Background: The optimal number of examined lymph nodes (ELN) for accurate staging and prognosis for esophageal cancer patients receiving neoadjuvant therapy remains controversial. This study aimed to evaluate the impact of ELN count on pathologic staging and survival outcomes and to develop a predictive model for lymph node positivity in this patient population.
Methods: Data were extracted from the Surveillance, Epidemiology, and End Results (SEER) database and a multicenter cohort.

Background: This study analyzed a large national cohort to compare treatment strategies and survival outcomes in metaplastic breast cancer (MtBC), a rare and aggressive subtype with poor treatment response.
Patients And Methods: Adult female patients with MtBC diagnosed between 2006 and 2021 were identified from the National Cancer Database and grouped by chemotherapy sequence (neoadjuvant vs. adjuvant) to evaluate clinical characteristics and survival outcomes.

Objectives: To evaluate the association between the KRAS mutational load and the histologic tumor response in patients with resectable pancreatic ductal adenocarcinoma (PDAC) who received neoadjuvant treatment (NAC) with pegylated liposomal irinotecan in combination with oxaliplatin, 5-fluorouracil, and leucovorin (NALIRIFOX).
Methods: This was a multicenter, single-arm, interventional, open-label, phase 2 trial in patients 18 years or older who had histologically or cytologically confirmed PDAC and were candidates for surgery and received neoadjuvant NALIRIFOX. The primary outcome was determination of the association between the KRAS mutational load and the histologic tumor response after chemotherapy.

Introduction: The prognosis of anaplastic thyroid carcinoma (ATC) remains poor. Mutation-based targeted therapies and immune checkpoint inhibitors (ICI) have gained increasing importance in the treatment of advanced tumor stages. This study aimed to investigate whether mutation-based neoadjuvant therapy can convert an initially unresectable tumor into a resectable state, optimizing local tumor control and prolonging overall survival.

Solitary fibrous tumor, formerly also referred to as hemangiopericytoma, is a fibroblastic mesenchymal neoplasm of the orbit that rarely metastasizes but has a propensity for local recurrence. We describe 5 cases of orbital solitary fibrous tumors that were treated with radiation. In 3 patients, radiation therapy was given in the neoadjuvant setting prior to surgery.
