Retrospective analysis of HPV infection: Cotesting and HPV genotyping in cervical cancer screening within a large academic health care system

AbstractBackgroundIn 2019, the American Society for Colposcopy and Cervical Pathology introduced fundamental shifts toward “risk‐based” guidelines, with human papillomavirus (HPV) genotyping as a principal test for investigating squamous intraepithelial lesions. This study aims to provide practice‐based evidence and supplement the updated guidelines by investigating HPV demographic distribution and uncovering the pathological features of high‐grade squamous intraepithelial lesions (HSILs) caused by high‐risk HPV (hrHPV) subtypes.MethodsPatients who underwent Papanicolaou screening and HPV testing in two hospital systems over the course of 4 years were recruited. The cytology results were categorized on the basis of the 2014 Bethesda classification. DNA sequences of 14 types of hrHPV were detected by Aptima test. The histological features of HSILs caused by different subtypes were compared between biopsies and excisions.ResultsA total of 63,709 cases were included. The HPV prevalence was 14.70%, predominantly in the 30 to 39‐year‐old age group, with slightly higher rates observed in African Americans. There was no significant racial distribution difference between HPV 16/18/45 and other types. HPV 16/18/45 infection was directly correlated with the severity of abnormal cytology, although the other subtypes were the major causes of cytological abnormalities. The trend for HPV prevalence was consistent across calendar years, and was associated with 8.77% negative for intraepithelial lesion or malignancy, 30.46% atypical squamous cell of undetermined significance, 64.62% low‐grade squamous intraepithelial lesion, 66.75% atypical squamous cell‐cannot exclude a high‐grade squamous intraepithelial lesion, and 91.80% HSIL. Furthermore, 29.09% of HSILs associated with other subtypes were not detectable on subsequent resections.ConclusionsGiven the HPV demographic distribution and the histological features of HSILs caused by different subtypes, cotesting with reflex HPV genotyping in specific populations, or expanding the subtypes in the primary HPV screening test, should be considered.

Unraveling the challenges of intravenous leiomyomatosis: a retrospective analysis of 11 cases

Abstract Objective This study provides a concise overview of diagnostic and treatment strategies for intravenous leiomyomatosis (IVL), a rare disease with nonspecific clinical manifestations, based on cases from a tertiary referral hospital in China. Methods We retrospectively analyzed 11 premenopausal patients with confirmed IVL between 2018 and 2022. Clinical data from Ultrasound, Enhanced CT, and MRI were studied, along with surgical details, postoperative pathology, and follow-up information. Results Premenopausal patients showed no disease-specific symptoms, with 90.9% having a history of gynecological or obstetric surgery, and 72.7% having prior uterine fibroids. Cardiac involvement was evident in two cases, with echocardiography detecting abnormal floating masses from the inferior vena cava. Pelvic ultrasound indicated leiomyoma in 90.9% of cases, with ≥ 50 mm size. Surgery was the primary treatment, and lesions above the internal iliac vein resulted in significantly higher intraoperative blood loss (median 1300 ml vs. 50 ml, p  = 0.005) and longer hospital stays (median 10 days vs. 4 days, p  = 0.026). Three patients with lesions above the inferior vena cava required combined surgery with cardiac specialists. Recurrence occurred in 2 out of 11 patients with incomplete lesion resection. Conclusions IVL mainly affects premenopausal women with uterine masses, primarily in the pelvic cavity (Stage I). Pelvic ultrasound aids early screening, while Enhanced CT or MR assists in diagnosing and assessing venous lesions. Complete resection is crucial to prevent recurrence. Lesions invading the internal iliac vein and above pose higher risks during surgery. A multidisciplinary team approach is essential for patients with lesions above the inferior vena cava, with simultaneous surgery as a potential treatment option.
