Gastric adenocarcinoma of the cervix (GAC) represents a rare mucinous endocervical cancer unrelated to human papillomavirus (HPV). GAC has been found to comprise approximately 10% of cervical adenocarcinomas internationally. As more cases have been identified, GAC has been further classified into subtypes such as poorly differentiated versus well-differentiated (also referred to as mucinous or adenoma malignum). This cancer coined the term "gastric" subtype due to its similarity to the pancreaticobiliary and gastric tissue lining. With limited data and similar histological and genetic features of GAC, this malignancy poses a challenge for clinicians when differentiating between metastasis from the gastrointestinal tract and GAC. Here, we present a case of a 55-year-old female who presented with postmenopausal bleeding and was found to have stage IA1 endocervical adenocarcinoma of gastric subtype. The purpose of this article is to introduce a rare type of gastric adenocarcinoma with a unique site of origin in order to better understand this disease process and potentially help clinicians better diagnose and treat patients with this malignancy in the future.

Background: Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE)-mediated membrane fusion is crucial for autophagy, making YKT6, a key modulator of cell membrane fusion, a potential target for cancer therapy. However, its oncogenic role across different cancers remains unclear. This study was to investigate the prognostic value and potential immunological functions of YKT6, including cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC).

Small-cell neuroendocrine cancer (SCNEC) of the uterine cervix is an exceedingly rare, highly aggressive tumor with an extremely poor prognosis. The cellular heterogeneity, origin, and tumorigenesis trajectories of SCNEC of the cervix remain largely unclear. We performed single-cell RNA sequencing and whole-exome sequencing on tumor tissues and adjacent normal cervical tissues from two patients diagnosed with SCNEC of the cervix.

BACKGROUND Neuroendocrine carcinoma (NEC) of the cervix is rare and has high mortality and recurrence rates. The clinical symptoms of cervical NEC, such as abnormal vaginal bleeding and discharge, are similar to those of other cervical cancers. Here, we describe a case involving a 42-year-old woman with cervical NEC accompanied by an isolated large ovarian metastasis.

Background: Chromosomal instability (CIN) has been identified as a factor that increases the susceptibility of tumor cells to kinesin family member 18A (KIF18A) inhibitors. Limited research exists on genes that are associated with sensitization to KIF18A inhibitors (KIF18Ais). Our study aimed to identify a gene linked to heightened sensitivity to KIF18Ais in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) and uterine corpus endometrial carcinoma (UCEC).
