Introduction: The authors describe their experience of surgical closure of the anterior skull base after tumour resection, using the posterior wall of the frontal sinus.
Material And Method: The authors describe their anterior skull base closure technique performed in three patients after tumour resection. Tumour resection via a transglabellar approach resulted in an anterior skull base defect. Reconstruction consisted of direct implantation of the posterior wall of the frontal sinus without using a bone substitute (except when nasofrontal duct obstruction is required).
Results: Three patients were operated by this surgical procedure with complete tumour resection in every case and no infectious complications. This technique was easy to perform, despite one case of persistent CSF leak. Follow-up imaging showed no displacement of the onlay bone graft.
Conclusion: Anterior skull base reconstruction after tumour resection using autologous frontal sinus bone graft is easy to perform with a low complication rate.

Background: Olfactory neuroblastoma (ONB) is a rare sinonasal malignancy primarily treated with surgery. For tumors arising from the olfactory area, traditional treatment involves transcribriform resection of the anterior cranial fossa. Surgery can be performed with unilateral or bilateral resection depending on extent of involvement; however, there are currently no studies comparing outcomes between the two.

Background: Combining radiotherapy (RT) with immune checkpoint inhibitors (ICIs) is a promising strategy that can enhance the therapeutic efficacy of ICIs. However, little is known about RT-induced changes in the expression of immune checkpoints, such as PD-L1, and their clinical implications in colorectal cancer (CRC). This study aimed to investigate the association between responsiveness to RT and changes in PD-L1 expression in human CRC tissue and cell lines.

Background: TG02 is a peptide-based cancer vaccine eliciting immune responses to oncogenic codon 12/13 mutations. This phase 1 clinical trial (NCT02933944) assessed the safety and immunological efficacy of TG02 adjuvanted by GM-CSF in patients with -mutant colorectal cancer.
Methods: In the interval between completing CRT and pelvic exenteration, patients with resectable mutation-positive, locally advanced primary or current colorectal cancer, received 5-6 doses of TG02/GM-CSF.

Background: Significant osseous defects or osteonecrosis, precipitated by open fractures, infections, or neoplastic conditions, represent infrequent yet critical medical conditions. The free vascularized fibular graft (FVFG) is a challenging but straightforward, reliable surgical intervention for the reconstruction of defects across various anatomical regions. This study aims to compare, quantify, and demonstrate the FVFG's versatility.

Managing acute coronary syndrome (ACS) in patients with a recent history of gastrointestinal bleeding presents a unique and challenging clinical dilemma, necessitating a careful balance between minimizing ischemic risk and avoiding potentially life-threatening rebleeding. Standard treatment for ACS typically involves dual antiplatelet therapy (DAPT) to prevent recurrent thrombotic events. However, in patients with recent gastrointestinal hemorrhage or significant anemia, these therapies may substantially increase the risk of life-threatening bleeding, complicating the decision-making process and often leading to conservative management strategies.
