Objective: To evaluate the frequency and malignancy rate of incidental focal uptake of 18F-fluorodeoxyglucose (FDG) in the breast on PET/computed tomography (CT).
Material And Methods: All PET/CT scan reports from a single institution from 2010 to 2017 were electronically searched for words or phrases related to FDG uptake in the breast. Potentially eligible PET/CT scans were manually reviewed for the presence of focal incidental findings in the breast, and a final diagnosis was established based on pathology, clinical examinations, and clinical follow-up.
Results: A total of 19 551 PET/CT scans were reviewed, from which 66 patients (0.3%) presented with unexpected focal FDG-avid lesions of the breast. Fifty-three patients (80.3%) had follow-up evaluations. The final diagnosis showed malignancies in 38 patients. Thirty-four patients had biopsy-verified cancer (primary breast cancers, n = 30; metastasis, n = 4), and four patients with known lymphoma showed a tumour response in the breast after chemotherapy. The malignancy rate was 85.0% among patients who underwent biopsy (34 of 40 patients). The SUVmax was significantly higher in patients with a final malignant diagnosis (n = 38) than in those with a benign diagnosis (n = 15) (4.5 ± 2.9 vs. 2.7 ± 1.3, P = 0.03).
Conclusion: Incidental uptake of FDG in the breast was rare. However, the malignancy rate was high among these patients, particularly among patients who had a follow-up biopsy. We recommend biopsy or thorough follow-up in patients with incidental focal uptake of FDG in the breast.

Gender Disparities and Lung Cancer Screening Outcomes Among Individuals Who Have Never Smoked.
JAMA Netw Open
January 2025
Division of Pulmonary and Critical Care Medicine, Department of Internal Medicine, Seoul National University Bundang Hospital, Seongnam, Republic of Korea.
Importance: Lung cancer in individuals who have never smoked (INS) is a growing global concern, with a rapidly increasing incidence and proportion among all lung cancer cases. Particularly in East Asia, opportunistic lung cancer screening (LCS) programs targeting INS have gained popularity. However, the sex-specific outcomes and drawbacks of screening INS remain unexplored, with data predominantly focused on women.

Introduction: Hodgkin lymphoma (HL) is a hematopoietic malignancy characterized by the presence of Reed Sternberg cells, with generally favourable outcomes compared to other hematological malignancies. This study aims to determine the socio-demographic, clinical and treatment characteristics, as well as the short-term overall survival (OS) and progression-free survival (PFS) rates, of HL patients treated at Hospital Universiti Sains Malaysia (USM), a tertiary centre in northeast peninsular Malaysia.
Materials And Methods: We conducted a retrospective cohort study of HL patients treated from January 1, 2006, to December 31, 2018, with follow-up until December 31, 2021.
Improved Predictability of Diagnosis and Prognosis Using Serum- and Tissue-Derived Extracellular Vesicles From Bulk mRNA Sequencing in Pancreatic Ductal Adenocarcinoma.
Cancer Med
January 2025
Department of Hepatobiliary and Pancreatic Surgery, Zhongnan Hospital of Wuhan University, Wuhan, China.
Background: Early-stage pancreatic ductal adenocarcinoma (PDAC) is frequently misdiagnosed, contributing to its high mortality rate. Exosomal microRNAs (miRNAs) have emerged as potential biomarkers for the early detection of PDAC.
Aims: This study aimed to evaluate the feasibility of using exosomal miRNAs from PDAC tissues and serum as biomarkers for early detection and prognosis.
Effect of Dendrobium Officinale on Radioactive Oral Mucositis of Nasopharyngeal Carcinoma and Changes of Oral Microecology.
Integr Cancer Ther
January 2025
Zhejiang Cancer Hospital, Hangzhou, Zhejiang, China.
Objective: To observe the clinical efficacy of Dendrobium officinale in the treatment of radiotherapy-induced oral mucositis in nasopharyngeal carcinoma patients, and to explore its regulating effect on immune function and oral microbiota by comparing immune-related factors and oral microbiota before and after the intervention.
Methods: We conducted a randomized double-blinded controlled trial in Zhejiang Cancer Hospital. Sixty patients with nasopharyngeal cancer combined with radiotherapy-induced oral mucositis were randomly divided into a study group and control group, with 30 cases in each group The study group used compound vitamin B12 solution and Dendrobium tea drink, and the control group simply used compound vitamin B12 solution rinse.

Dept of Surgical Oncology, Aster International Institute of Oncology, Bangalore, India.
Background: The role of enhanced recovery after surgery (ERAS) in cytoreductive surgery and/or Hyperthermic Intraperitoneal Chemotherapy HIPEC) is evolving, with promising results that improve patient outcomes. This consensus exercise was carried out to address and standardize components of the ERAS protocol pertinent to the Indian context.
Method: The modified Delphi method was employed with two rounds of voting.
