Advancements in nuclear imaging using radiolabeled nanobody tracers to support cancer immunotherapy.

The evolving landscape of cancer immunotherapy has revolutionized cancer treatment. However, the dynamic tumor microenvironment has led to variable clinical outcomes, indicating a need for predictive biomarkers. Noninvasive nuclear imaging, using radiolabeled modalities, has aided in patient selection and monitoring of their treatment response.

Potential application of [F]AlF-PSMA-11 PET/CT in radioiodine refractory thyroid carcinoma.

Background: Patients diagnosed with radioiodine refractory (RAI-R) thyroid carcinoma (TC) have a significantly worse prognosis than patients with radiosensitive TC. These refractory malignancies are often dedifferentiated, hindering the effectiveness of iodine-based imaging. Additionally, the role of metabolic imaging using [F]FDG PET/CT is also limited in these cases, making adequate staging of RAI-R TC challenging.

The development of a research-based interprofessional communication behaviors repository in healthcare education: A systematic review.

Interprofessional communication is crucial for patient care, yet there is a dearth of comprehensive assessment tools essential to train and assess healthcare students. While the Interprofessional Educational Collaborative framework (IPEC) outlines eight sub-competencies, it lacks detailed behavioral indicators. This study aimed to create a repository of interprofessional communication behaviors to complement the IPEC sub-competencies.

Choice of surgery in intestinal-type adenocarcinoma of the sinonasal tract: a long-term comparative study.

Purpose: Intestinal-type adenocarcinoma (ITAC) is a rare sinonasal malignancy. Curative treatment requires multidisciplinary approach, with surgical options consist of the endonasal endoscopic approach (EEA) and external surgery (EXTS). Here, we provide the post-operative and survival results from a single-center long-term follow-up.

Salvage total laryngectomy for squamous cell carcinoma of the larynx and hypopharynx: Validated prognostic nomograms predicting oncological outcomes.

Background: Salvage total laryngectomy (STL) is a preferred treatment for patients with residual, recurrent, and second primary squamous cell carcinoma of the larynx/hypopharynx after (chemo)radiation. To individually estimate postoperative oncological outcomes, we designed and validated prognostic nomograms.

Methods: We used a dataset of 290 patients who underwent STL.

Safety assessment of fluorescently labeled anti-EGFR Nanobodies in healthy dogs.

Surgical resection is one of the main treatment options for several types of cancer, the desired outcome being complete removal of the primary tumor and its local metastases. Any malignant tissue that remains after surgery may lead to relapsing disease, negatively impacting the patient's quality of life and overall survival. Fluorescence imaging in surgical oncology aims to facilitate full resection of solid tumors through the visualization of malignant tissue during surgery, following the administration of a fluorescent contrast agent.

Current status and future expectations of nanobodies in oncology trials.

Introduction: Monoclonal antibodies have revolutionized personalized medicine for cancer in recent decades. Despite their broad application in oncology, their large size and complexity may interfere with successful tumor targeting for certain applications of cancer diagnosis and therapy. Nanobodies have unique structural and pharmacological features compared to monoclonal antibodies and have successfully been used as complementary anti-cancer diagnostic and/or therapeutic tools.

Direct co-registration of [F]FDG uptake and histopathology in surgically excised malignancies of the head and neck: a feasibility study.

Purpose: Recent technical advancements in PET imaging have improved sensitivity and spatial resolution. Consequently, clinical nuclear medicine will be confronted with PET images on a previously unfamiliar resolution. To better understand [F]FDG distribution at submillimetric scale, a direct correlation of radionuclide-imaging and histopathology is required.

High-Resolution F-FDG PET/CT for Assessing Three-Dimensional Intraoperative Margins Status in Malignancies of the Head and Neck, a Proof-of-Concept.

The surgical treatment of head and neck malignancies relies on the complete removal of tumoral tissue, while inadequate margins necessitate the use of adjuvant therapy. However, most positive margins are identified postoperatively as deep margins, and intraoperative identification of the deep positive margins could help achieve adequate surgical margins and decrease adjuvant therapies. To improve deep-margin identification, we investigated whether the use of high-resolution preclinical PET and CT could increase certainty about the surgical margins in three dimensions.

The Prognostic Value of CD206 in Solid Malignancies: A Systematic Review and Meta-Analysis.

An increased presence of CD206-expressing tumor associated macrophages in solid cancers was proposed to be associated with worse outcomes in multiple types of malignancies, but contradictory results are published. We performed a reproducible systematic review and meta-analysis to provide increased evidence to confirm or reject this hypothesis following the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. The Embase, Web of Science, and MEDLINE-databases were systematically searched for eligible manuscripts.

Functional Outcomes and Complications After Salvage Total Laryngectomy for Residual, Recurrent, and Second Primary Squamous Cell Carcinoma of the Larynx and Hypopharynx: A Multicenter Retrospective Cohort Study.

We analyzed complications and functional outcomes and aimed at identifying prognostic factors for functional outcomes and complications in patients who underwent salvage total laryngectomy (STL) for residual, recurrent, and second primary squamous cell carcinoma (SCC) of the larynx and hypopharynx after initial (chemo)radiation. Retrospective cohort study of patients who underwent STL in four major Belgian reference hospitals between 2002 and 2018. Prognostic factors for functional outcomes and complications were identified with uni- and multivariable analysis.

Oncologic Outcomes After Salvage Laryngectomy for Squamous Cell Carcinoma of the Larynx and Hypopharynx: A Multicenter Retrospective Cohort Study.

Objective: We aimed to analyze oncologic outcomes and identify patterns of failure and negative prognostic factors in patients who underwent salvage total laryngectomy (STL) for residual, recurrent, and second primary squamous cell carcinoma (SCC) of the larynx and hypopharynx.

Methods: This was a retrospective cohort study of patients who underwent STL in four major Belgian reference hospitals between 2002 and 2018 for residual/recurrent/second primary SCC in the larynx or hypopharynx after initial (chemo)radiation. Prognostic factors for oncologic outcomes were identified using univariable and multivariable analysis.

Identifying non-otologic risk factors for tinnitus: A systematic review.

Background: The origin of tinnitus has been attributed to a peripheral auditory lesion, inducing bottom-up changes and resulting in the perception of a "phantom sound." However, non-auditory factors can co-exist as well, and can even lie at the origin of tinnitus development. An increasing body of literature focuses on psychological, (neuro)muscular, cardiovascular and many other influences and their respective associations with tinnitus prevalence.

GGCX-Associated Phenotypes: An Overview in Search of Genotype-Phenotype Correlations.

Gamma-carboxylation, performed by gamma-glutamyl carboxylase (GGCX), is an enzymatic process essential for activating vitamin K-dependent proteins (VKDP) with important functions in various biological processes. Mutations in the encoding gene are associated with multiple phenotypes, amongst which vitamin K-dependent coagulation factor deficiency (VKCFD1) is best known. Other patients have skin, eye, heart or bone manifestations.
