Rasburicase is a recombinant form of urate oxidase, a medication used to treat hyperuricemia by metabolizing uric acid into an inactive and more soluble metabolite, allantoin. An oxidizing agent, hydrogen peroxide, is produced during the conversion of uric acid to allantoin. We present here a case of hemolytic anemia secondary to rasburicase treatment which was later confirmed to have glucose-6-phosphate dehydrogenase deficiency (G6PDD).

Importance: Combined modality therapy, such as chemoradiotherapy, often results in significant morbidity among patients with head and neck cancer. Although the role of body mass index (BMI) varies based on cancer subtypes, its association with treatment response, tumor recurrence, and survival outcomes among patients with head and neck cancer remains unclear.

Objective: To evaluate the role of BMI in treatment response, tumor recurrence, and survival outcomes among patients with head and neck cancer undergoing chemoradiotherapy.

Article Synopsis
  • Recent studies challenge the 10 pack-years smoking threshold previously used for risk assessment, leaving the actual threshold undefined.
  • A study focusing on head and neck cancer patients found that exceeding 22 pack-years of smoking is linked to worse overall survival and progression-free survival.
  • Analysis showed that heavy smokers (more than 22 pack-years) have a higher risk of distant failure, while no significant risk was found with the previously used 10 pack-years threshold.

Article Synopsis
  • This study aimed to determine the best hemoglobin (Hgb) threshold for predicting outcomes in head and neck cancer patients undergoing chemoradiation, identifying 11.4 as the critical level.
  • Among 496 patients analyzed, low Hgb levels (below 11.4) correlated with significantly worse overall survival (OS) and progression-free survival (PFS), especially in those with HPV-negative tumors.
  • The findings suggest that while low Hgb is a strong negative prognostic factor for patients with HPV-negative head and neck cancers, it does not significantly impact those with HPV-positive tumors.

Importance: Given the role of inflammation in cancer progression, neutrophil-lymphocyte ratio (NLR) from peripheral blood has been suggested as a readout of systemic inflammation and a prognostic marker in several solid malignant neoplasms. However, optimal threshold for NLR in US patients with head and neck cancer remains unclear.

Objective: To evaluate the optimal NLR threshold as a potential prognostic biomarker for survival outcomes.

Physicians, including radiologists and specifically breast imagers, face many challenges, and stressors during their daily routine, many of which can contribute to burnout. While there is an increasing body of literature evaluating burnout, including its prevalence in and impact on radiologists, there is a relative lack of information specifically addressing this topic as it relates to breast imaging. This article reviews key concepts in burnout, describes the potential impact on physicians at all levels of training and work, highlights unique aspects to the specialty of breast imaging that may contribute to burnout, and suggests tool and/or strategies that may help to combat and prevent burnout among breast imagers.
