Background: Computed tomography to body divergence (CTBD) is one of the main barriers to bronchoscopic techniques for the diagnosis of peripherally located lung nodules. Cone-beam CT (CBCT) guidance is being rapidly adopted to correct for this phenomenon and to potentially increase diagnostic outcomes. In this trial, we hypothesized that the addition of mobile CBCT (m-CBCT) could improve the rate of tool in lesion (TIL) and the diagnostic yield of shape-sensing robotic-assisted bronchoscopy (SS-RAB).

Article Synopsis
  • The study aimed to analyze the outcomes of different mammography screening strategies for breast cancer, focusing on various start and stop ages as well as screening intervals.
  • Using six cancer modeling models, the research found that biennial digital breast tomosynthesis (DBT) screening starting at ages 40, 45, or 50 significantly reduced breast cancer deaths, with the most effective strategy a 30% reduction in mortality for those screened from age 40 to 74.
  • While annual screening offered higher benefits, it also led to increased false-positive recalls and overdiagnosis, showing a critical need to balance benefits against potential harms in screening recommendations.

  • Hypomagnesemia, a common side effect of platinum-based chemotherapy, can negatively impact overall survival, and traditional magnesium replacements may not be effective.
  • This study examined the feasibility of a magnesium-rich diet in patients with ovarian cancer undergoing carboplatin treatment, providing weekly education to enhance dietary intake.
  • Results showed that adherence to the diet led to increased magnesium consumption and reduced the incidence of hypomagnesemia, suggesting dietary approaches can help maintain magnesium levels during chemotherapy.

Article Synopsis
  • Atelectasis is a common issue during bronchoscopy under general anesthesia and can negatively impact navigation and diagnostic results; the study aimed to assess the severity of this condition in patients.
  • The researchers developed an Atelectasis Severity Score System (ASSESS) to classify the severity of atelectasis based on specific lung zones, finding that 47% of patients had mild and moderate atelectasis, while 6% experienced severe atelectasis.
  • Results indicated that a higher Body Mass Index (BMI) increases the odds of developing greater severity of atelectasis, whereas the VESPA trial reduced these odds, highlighting the need for preventive strategies in at-risk patients, especially in specific lung zones.

Article Synopsis
  • The study aimed to evaluate the safety and cardiovascular outcomes of cancer patients with heart failure (HF) who were treated with midodrine for hypotension.
  • A total of 85 patients were analyzed, showing various types of HF, with the primary reason for midodrine use being orthostatic hypotension; side effects were generally minimal.
  • No significant differences in heart function or mortality risk were found between those who continued midodrine and those who stopped, although elevated creatinine levels were linked to higher mortality risk.

Background: Sapanisertib (CB-228/TAK-228) is a potent, selective ATP-competitive, dual inhibitor of mTORC1/2. Metformin is thought to inhibit the mTOR pathway through upstream activation of 5'-AMP-activated protein kinase (AMPK) suggesting combination therapy may enhance antitumor activity of sapanisertib. We report preliminary safety, tolerability, and efficacy from the dose-escalation study of sapanisertib in combination with metformin in patients with advanced solid tumors.

Article Synopsis
  • Patients with preexisting autoimmune diseases (pAIDs) are often excluded from clinical trials of immune checkpoint inhibitors (ICIs) due to concerns about exacerbating their conditions.
  • This study compared the safety of ICI combinations versus monotherapy in cancer patients with pAIDs, focusing on immune-related adverse events (irAEs) and treatment outcomes like progression-free survival (PFS).
  • Results indicated that while ICI combination therapy had a higher incidence of any-grade irAEs compared to monotherapy, overall, the toxicity profile was manageable, and no treatment-related deaths occurred, suggesting that the combination therapy could be safe for these patients.

Immune-related adverse events (irAEs) challenge the use of immune checkpoint inhibitors (ICIs). We performed a retrospective study to evaluate response to infliximab for immune-related adverse event management, and infliximab's effect on progression-free survival (PFS) and overall survival (OS) with a focus on melanoma and genitourinary cancers. We retrospectively reviewed records of all cancer patients exposed to infliximab after immune checkpoint inhibitor (ICI) treatment from 2004 to 2021 at the MD Anderson Cancer Center.
