Forkhead box L2 (FOXL2) encodes a transcription factor essential for sex determination, and ovary development and maintenance. Mutations in this gene are implicated in syndromes involving premature ovarian failure and granulosa cell tumors (GCTs). This rare cancer accounts for less than 5% of diagnosed ovarian cancers and is causally associated with the FOXL2 c.

Background: Granulosa cell ovarian tumors (GCTs) are a rare neoplasia characterized by a pathognomonic mutation in the FOXL2 gene. In vitro studies have demonstrated an overactivation of hormone activity due to this alteration. Thus, we aimed to determine the activity of orteronel, a CYP17 inhibitor, in advanced disease.

Background: The mandible provides valuable insights into its biological identity. However, the existence of several terminologies for mandibular measurements and inconsistent language can lead to misinterpretation, confusion, and miscommunication.

Highlight: A standardised set of anatomical points, planes, and measurements would assist with these issues and ensure reproducibility and comparability.

Article Synopsis
  • Precision medicine is changing how we treat cancer, but many patients still lack access to the necessary genetic testing and treatments.
  • A study in Spain examined how providing free RNA sequencing tests impacted the treatment of solid cancer patients who had already failed standard therapies, analyzing samples from 395 patients.
  • The results showed actionable genetic alterations in 14.4% of patients, leading to limited use of targeted therapies, highlighting a need for better access to comprehensive molecular testing and personalized treatments.

Background And Purpose: Despite that incorporating antiangiogenic in combination with immune-checkpoint inhibitors as the standard first-line treatment for advanced clear cell renal cell cancer (ccRCC) yields promising outcomes, these regimens often lead to significant toxicity. However, a subgroup of patients has shown responsiveness to VEGFR tyrosine-kinase inhibitors (TKIs) in monotherapy, leading to the question of whether employing combination therapies can significantly enhance overall survival in all patients over monotherapy. Thus, we aim to identify gene expression signatures that can predict TKI response within subpopulations that might benefit from single-agent therapies, to minimize unnecessary exposure to combination therapies and their associated toxicities, as well as to discover new potential therapeutic targets to improve ccRCC treatment.

Article Synopsis
  • The SWI/SNF complex is made up of proteins that help control how our DNA is organized, and mutations in these proteins can cause dangerous cancers in young people.
  • These aggressive cancers, like rhabdoid tumors and epithelioid sarcoma, are hard to treat and often do not have good outcomes for patients.
  • A study called TILTS is testing a new treatment that uses special immune cells from the patients (called TILs) that can spot and attack these tumors, making it an exciting area of research for better therapies.

Geometric morphometrics (GMM) have been applied to understand morphological variation in biological structures. However, research studying cortical bone through geometric histomorphometrics (GHMM) is scarce. This research aims to develop a landmark-based GHMM protocol to depict osteonal shape variation in the femoral diaphysis, exploring the role of age and biomechanics in bone microstructure.

Fibroblast growth factor receptor (FGFR) alterations drive oncogenesis in multiple tumor types. Here we studied pemigatinib, a selective, potent, oral FGFR1-FGFR3 inhibitor, in the phase 2 FIGHT-207 basket study of FGFR-altered advanced solid tumors. Primary end points were objective response rate (ORR) in cohorts A (fusions/rearrangements, n = 49) and B (activating non-kinase domain mutations, n = 32).

Cancer-derived small extracellular vesicles (sEVs) are capable of modifying the tumor microenvironment and promoting tumor progression. Ovarian cancer (OvCa) is a lethal malignancy that preferentially spreads through the abdominal cavity. Thus, the secretion of such vesicles into the peritoneal fluid could be a determinant factor in the dissemination and behavior of this disease.

This report presents the case of a 62-year-old woman who was diagnosed in 1999 with stage I cervical carcinoma treated by surgical resection. In 2021, she presented to the emergency department with a complaint of predominantly right-sided lower back pain. A CT scan of the lumbosacral region revealed a bone lesion in the L5 vertebra and retroperitoneal lymphadenopathies suggestive of malignancy.

Background: Fibroblast growth factor receptor 3 (FGFR3) alterations are oncogenic drivers of urothelial carcinoma (UC). Pemigatinib is a selective, oral inhibitor of FGFR1-3 with antitumor activity. We report the efficacy and safety of pemigatinib in the open-label, single-arm, phase II study of previously treated, unresectable or metastatic UC with FGFR3 alterations (FIGHT-201; NCT02872714).

  • Cancer patients with COVID-19 had to stop their treatments and went to the hospital more often than those without COVID-19.
  • The study looked at 85 kidney cancer patients, comparing those who had COVID-19 while on different treatments.
  • Even though COVID-19 caused treatment issues, it didn't seem to hurt the cancer outcomes for the patients.

Vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs) are key antiangiogenic drugs for renal cancer treatment. While Von Hippel-Lindau dysfunction constitutes the base for VEGFR-TKIs sensitivity, the role for individual and concurrent mutations in the genes encoding for the chromatin remodelers Polybromo-1 () and Lysine Demethylase 5C () is poorly understood. Here, we analyzed the tumor mutational and expression profiles of 155 unselected clear cell RCC (ccRCC) cases treated with first-line VEGFR-TKIs and the ccRCC cases of IMmotion151 trial were used for validation.

Background: Managing the inflammatory response to SARS-Cov-2 could prevent respiratory insufficiency. Cytokine profiles could identify cases at risk of severe disease.

Methods: We designed a randomized phase II clinical trial to determine whether the combination of ruxolitinib (5 mg twice a day for 7 days followed by 10 mg BID for 7 days) plus simvastatin (40 mg once a day for 14 days), could reduce the incidence of respiratory insufficiency in COVID-19.

Cortical bone microstructure assessment in biological and forensic anthropology can assist with the estimation of age-at-death and animal-human differentiation, for example. Osteonal structures within cortical bone are the key feature under analysis, with osteon frequency and metric parameters providing crucial information for the assessment. Currently, the histomorphological assessment consists of a time-consuming manual process for which specific training is required.

  • - Erdafitinib is used to treat adults with advanced urothelial carcinoma who have not responded to prior platinum-based chemotherapy, aiming to understand the frequency and management of side effects from this treatment.
  • - In the BLC2001 clinical trial, 101 patients were treated with a specific dosage and monitoring for side effects like hyperphosphatemia, stomatitis, and skin issues, with most side effects being mild (grade 1 or 2) and manageable.
  • - Results showed that while some adverse events did occur, they were typically manageable, leading to few patients needing to stop treatment, but more research is necessary to see if these management strategies apply to a broader patient population.

Background: Granulosa cell ovarian tumor (GCT) is characterized by a pathognomonic mutation in the FOXL2 gene (402 C > G) that leads to an overactivation of steroidogenesis. CYP17 is a key enzyme in such process and can be inhibited by ketoconazole.

Methods: We designed a phase II clinical trial to assess the efficacy of ketoconazole in advanced GCT and conducted several in vitro studies to support the clinical findings.

Histomorphometry constitutes a valuable tool for age estimation. Histological interpopulation variability has been shown to affect the accuracy of age estimation techniques and therefore validation studies are required to test the accuracy of the pre-existing methodologies. The present research constitutes a validation study of widely known histological methods on the sixth rib and the femoral midshaft of a 19th century British population originating from Blackburn, England.
