Background: Cervical high-grade squamous intraepithelial lesion (HSIL), a precancerous condition, can progress to cervical squamous cell carcinoma (CSCC), the most prevalent histological subtype of cervical cancer. Although CSCC most commonly metastasizes via lymphatic or hematogenous routes, contiguous superficial spread to the endometrium, fallopian tubes, and ovaries is rare.
Case Presentation: A 61-year-old postmenopausal woman was referred to our hospital for further evaluation after a positive HPV-16 test and normal ThinPrep Cytologic Test (TCT) results during a routine health examination at an external institution two weeks earlier. Histopathological examination of colposcopy-guided biopsies confirmed chronic cervicitis with HSIL. Notably, the serum squamous cell carcinoma antigen (SCC-Ag) level was markedly elevated (32.20 ng/mL). Transvaginal color Doppler ultrasonography revealed a cystic mass in the right pelvic region. Intraoperative laparoscopic findings included a tortuous, thickened right fallopian tube with fimbrial occlusion. Gross pathological examination revealed an irregular grayish-white endometrial lesion measuring 2.5*2.0 cm. The right fallopian tube exhibited focal dilation, measuring 1.6 cm in diameter. No gross abnormalities were detected in the right ovary. Final histopathology confirmed extensive cervical HSIL (CIN III) with multifocal stromal invasion (maximum depth: 4 mm), which involved the endometrium, right fallopian tube mucosa, and an ovarian inclusion cyst on the ipsilateral side.
Conclusion: Cervical HSIL/SCC may exhibit superficial upward extension to the endometrium and, in rare cases, can involve the ovaries. Although rare, this clinical entity warrants increased clinical vigilance. Currently, no standardized management guidelines exist for this distinct metastatic pattern, and emerging evidence suggests a multifactorial pathogenesis. These findings underscore the need for enhanced early detection and preventive strategies.

Objectives: Bladder cancer is a common malignancy with high incidence and poor prognosis. N-methyladenosine (mA) modification is widely involved in diverse physiological processes, among which the mA recognition protein YTH N-methyladenosine RNA binding protein F2 (YTHDF2) plays a crucial role in bladder cancer progression. This study aims to elucidate the molecular mechanism by which O-linked -acetylglucosamine (O-GlcNAc) modification of YTHDF2 regulates its downstream target, period circadian regulator 1 (), thereby promoting bladder cancer cell proliferation.

In obstructive sleep apnea (OSA), repeated airway obstruction alters mucosal inflammation, which increases exhaled nitric oxide (NO) production in the nasal cavity. However, the underlying mechanism remains unclear. Accordingly, we aimed to examine the mechanism underlying NO production in patients with OSA.

Esophageal cancer is a major cause of cancer-related death, often preceded with chronic inflammation and injuries. The NFκB/IKKβ pathway plays a central role in inflammation, yet its role in early esophageal carcinogenesis remains unclear. This study investigated the role of epithelial IKKβ in early esophageal carcinogenesis.

Objectives: To study the impact of SURF4 expression level on long-term prognosis of gastric cancer (GC) and biological behaviors of GC cells.
Methods: SURF4 expression level in GC and its association with long-term patient prognosis were analyzed using publicly available databases and in 155 GC patients with low and high SURF4 expressions detected immunohistochemically. The Cox proportional hazard model and Kaplan-Meier survival curves were used to analyze independent prognostic predictors of GC and the 5-year survival rate of the patients with different SURF4 expression levels.

Objectives: To investigate the role of circular RNA circ_0000437 in regulating biological behaviors of breast cancer cells and the molecular mechanism.
Methods: Breast cancer MCF-7 and MDA-MB-231 cells were transfected with sh-circ_0000437, mimics, inhibitor, si-CTPS1, or their respective negative controls. qRT-PCR was used to detect the expression levels of circ_0000437, let-7b-5p, CTPS1, Notch1, Hes1, and Numb in breast cancer cell lines and tissues.
