Although the lung is the most common site of metastasis from extrapulmonary malignancies, endobronchial metastases (EBM) are relatively rare. EBM typically originate from breast, colorectal, or kidney cancer. EBM from uterine cervical cancer is relatively rare and is difficult to confirm. In this study, we report a case of EBM in a patient with previously treated uterine cervical cancer. In this case, differentiation of the EBM from primary bronchogenic carcinoma with clinical, radiological, and pathologic findings was difficult. As identical human papillomavirus (HPV)-16 DNA was detected in both the EBM and in previously resected tissues from the prior uterine cervical cancer, the patient was diagnosed with EBM from uterine cervical cancer. HPV genotyping may aid in discriminating EBM from primary bronchogenic carcinoma in patients with uterine cervical cancer.

Background: Cervical cancer (CC) is a prevalent gynecological malignancy, contributing to a substantial number of fatalities among women. MicroRNAs (miRNAs) have emerged as promising biomarkers with significant potential for the early detection and prognosis of CC.
Objective: This study aimed to explore the clinical significance and biological role of miR-615-5p in CC, with the goal of identifying novel biomarkers for this disease.

Background: In uterine cervical cancer (UCC), tumour staging is performed according to the 2018 International Federation of Gynecology and Obstetrics (FIGO) system, where imaging is incorporated, or the more generic Tumour Node Metastasis (TNM) classification. With the technical development in diagnostic imaging, continuous prospective evaluation of the different imaging methods contributing to stage determination is warranted. The aims of this interim study were to (1) evaluate the performance of radiological FIGO (rFIGO) and T staging (rT) with 2-fluorine-18-fluoro-deoxy-glucose (2[18F]-FDG)-positron emission tomography with computed tomography (PET/CT) and with magnetic resonance imaging (PET/MRI), compared to clinical FIGO (cFIGO) and T (cT) staging based on clinical examination and conventional imaging, in treatment-naïve UCC, and to (2) identify possible MRI biomarkers for early treatment response after radiotherapy.

Objectives: Long non-coding RNAs (lncRNAs) play an essential role in cancer biology. Cervical intraepithelial neoplasia grade 3 (CIN3) is the most severe precancerous lesion of cervical cancer. However, the mechanism of multiple lncRNAs in CIN3 has not been studied in-depth and is worth exploring.

Introduction: The incidence of cervical cancer in French Guiana is among the highest worldwide. It ranks 5th among all cancers and is the 2nd most common cancer in women after breast cancer. The primary objective of this study was to establish the proportion of high-grade cytological lesions of the cervix in women under 25 years of age who underwent a cervico-uterine smear (CUS) in French Guiana over a 10-year period.
