A Chinese Cohort of Cervical Large Cell Neuroendocrine Carcinoma

Overview

Cervical large cell neuroendocrine carcinoma (LCNEC) exhibits highly aggressive biological behavior, including strong invasiveness, a high propensity for metastasis, drug resistance, and poor prognosis, necessitating heightened clinical and pathological awareness. This study aims to summarize the clinical characteristics of LCNEC and analyze various prognostic factors to enhance understanding and vigilance toward this disease. Combined with precise pathological diagnosis, improving diagnostic accuracy is crucial for formulating treatment strategies and assessing patient prognosis.

This study will collect the complete medical records of patients with cervical large cell neuroendocrine carcinoma registered in the participating tertiary hospitals, and will prospectively collect the medical records of patients diagnosed with cervical large cell carcinoma. The data to be collected includes: * Patient demographics (age, place of origin, occupation, etc.) * Medical history and test results prior to initial treatment: * Present illness history * Tumor marker levels * Pelvic ultrasound * Whole abdomen CT/MRI * PET-CT * Surgical treatment details (date of surgery, surgical approach) * Pathological examination results * Administration of neoadjuvant chemotherapy and/or radiotherapy * Detailed records of all treatment courses and their efficacy (including chemotherapeutic agents, radiotherapy doses, number of cycles, etc.) * Results from follow-up examinations and imaging studies * Recurrence status and, if applicable, time to recurrence * Survival status and, if applicable, date of death For the retrospective cohort, follow-up will be completed within one month after enrollment to document current survival status and recurrence. For the prospective cohort, annual follow-ups will be conducted to record current survival status and recurrence.
