Histopathological and Immunophenotypic Changes of Pancreatic Neuroendocrine Tumors after Neoadjuvant Peptide Receptor Radionuclide Therapy (PRRT).

Peptide Receptor Radionuclide Therapy (PRRT) is an emerging therapeutic option for pancreatic neuroendocrine tumors (PanNETs). A possible role for PRRT as a neoadjuvant agent is still largely undetermined, explored only in case reports or small case series. Likewise, the histopathological and immunophenotypic changes induced by PRRT are poorly characterized.

Rare sites of breast cancer metastasis: a review.

Breast cancer (BC) metastasis accounts for the majority of deaths from BC. The rate of metastasis to uncommon sites is on the rise due to the more effective therapy prolonging survival and to the early detection on imaging. The evaluation of patient-reported symptoms is essential in detecting a recurrence as early as possible, which may impact survival.

Identification and monitoring of somatic mutations in circulating cell-free tumor DNA in lung cancer patients.

Objectives: Circulating cell-free tumor DNA (ctDNA) isolated from the peripheral blood of non-small-cell lung cancer (NSCLC) patients provides biomarkers for both therapeutic target selection, particularly when direct tumor biopsy is unfeasible, and also for drug resistance monitoring. This study evaluates the reliability and feasibility of ctDNA analysis in an in-house clinical molecular diagnostic workflow.

Materials And Methods: Mutation profiling by both standard methods and Next-Generation sequencing (NGS) was carried out and compared on 2 independent lung cancer patient cohorts.

Diagnosis and Treatment of Laryngeal Schwannoma: A Systematic Review.

Objective This review summarizes the clinical features, diagnostic workup, and surgical treatment of laryngeal schwannoma with the aim of providing guidance for the management of this rare disease. The collated data allowed the statistical testing of several hypotheses, including the efficacy of endoscopic vs open surgical intervention and the usefulness of preoperative biopsy. Data Sources PubMed, Google Scholar, Cochrane, and SCOPUS.
