: Cervical cancer is a significant global health concern, with high incidence and mortality rates, especially in less-developed regions. [F]FDG PET/CT is now indicated at various stages of management, but its analysis is essentially based on SUVmax, a measure of [F]FDG uptake. Radiomics, by extracting a multitude of parameters, promises to improve the diagnostic and prognostic performance of the examination.

: The aim is to propose a model for predicting occult paraaortic lymph node (PALN) involvement in locally advanced cervical cancer (LACC) patients by including parameters such as reconstruction detection technology (use of time-of-flight) and parameters related to the primary tumor. This model will then be compared with the scores used in routine clinical practice; : This retrospective observational cohort study included patients diagnosed with LACC who underwent F-FDG PET/CT prior to PALN surgical staging between February 2012 and May 2020. The following parameters were collected on PET/CT: tumor SUVmax, tumor MTV, number of common and distal pelvic node involvements.

Article Synopsis
  • Optimizations in immunotherapy for Triple-negative breast cancer (TNBC) show promise, particularly in targeting galectin-9 (Gal-9) after radiotherapy.
  • In TNBC patients receiving neoadjuvant radiotherapy, higher Gal-9 levels were observed in non-responders compared to baseline, indicating a potential link between Gal-9 expression and treatment response.
  • A study in mice showed that targeting Gal-9 with an antibody led to reduced tumor growth only in those injected with irradiated cancer cells, suggesting Gal-9's potential as a biomarker and therapeutic target in TNBC.

Article Synopsis
  • Immune-checkpoint inhibitors (ICI) have transformed cancer treatment by utilizing the immune system, but they can cause serious, life-threatening immune-related adverse events (irAE) that can affect various organs.
  • Analysis of data from the international pharmacovigilance database revealed 25 types of irAE across over 50,000 cases, with skin reactions and pneumonitis being the most common, and a shift in treatment regimens favoring anti-PD1 and anti-PDL1 therapies after 2016.
  • Specific risk factors for certain irAE include cancer types and treatment regimens, with a median onset time for complications varying greatly; this underscores the importance of monitoring during ICI therapy

This study investigates the impact of sample type on the measurement of 25-OH-vitamin D using the Liaison XL (Diasorin) and Cobas e801 (Roche). This investigation was motivated by the need to optimize sample volume usage, which led us to adopt the use of heparin plasma, an alternative proposed by Diasorin in their specification. Discordant and unexplainable results were observed, prompting us to evaluate the effect of sample type on the accuracy of the 25-OH-vitamin D measurements.

Synchronous bilateral breast cancer (sBBC) occurs after both breasts have been affected by the same germline genetics and environmental exposures. Little evidence exists regarding immune infiltration and response to treatment in sBBCs. Here we show that the impact of the subtype of breast cancer on levels of tumor infiltrating lymphocytes (TILs, n = 277) and on pathologic complete response (pCR) rates (n = 140) differed according to the concordant or discordant subtype of breast cancer of the contralateral tumor: luminal breast tumors with a discordant contralateral tumor had higher TIL levels and higher pCR rates than those with a concordant contralateral tumor.
