Abstract
Background: Bladder neuroendocrine tumors are few and exhibit a high degree of aggressiveness. The bladder is characterized by four distinct forms of neuroendocrine tumors. Among them, large-cell neuroendocrine carcinoma is the least prevalent, but has the highest level of aggressiveness. The 5-year survival rate for large-cell neuroendocrine carcinoma of the bladder is exceedingly poor. To date, only a few dozen cases have been reported.
Case summary: Here, we report the case of a 65-year-old man with large-cell neuroendocrine carcinoma of the bladder. The patient presented to the Department of Urology at our hospital due to the presence of painless hematuria without any identifiable etiology. During hospitalization, abdominal computed tomography revealed the presence of an irregular mass on the right anterior wall of the bladder. A cystoscopic non-radical resection of the bladder lesion was performed. The postoperative pathological examination revealed large-cell neuroendocrine bladder cancer. Previous reports on cases of large-cell neuroendocrine carcinoma cases were retrieved from PubMed, and the present paper discusses the currently recognized best diagnostic and treatment options for large-cell neuroendocrine carcinoma based on the latest research progress.
Conclusion: Large-cell neuroendocrine carcinoma of the bladder is an uncommon malignancy with a highly unfavorable prognosis. Despite ongoing efforts to prolong patient survival through multidisciplinary therapy, the prognosis remains unfavorable. Large-cell neuroendocrine carcinoma continues to be a subject of uncertainty.
期刊介绍：
The WJCO is a high-quality, peer reviewed, open-access journal. The primary task of WJCO is to rapidly publish high-quality original articles, reviews, editorials, and case reports in the field of oncology. In order to promote productive academic communication, the peer review process for the WJCO is transparent; to this end, all published manuscripts are accompanied by the anonymized reviewers’ comments as well as the authors’ responses. The primary aims of the WJCO are to improve diagnostic, therapeutic and preventive modalities and the skills of clinicians and to guide clinical practice in oncology. Scope: Art of Oncology, Biology of Neoplasia, Breast Cancer, Cancer Prevention and Control, Cancer-Related Complications, Diagnosis in Oncology, Gastrointestinal Cancer, Genetic Testing For Cancer, Gynecologic Cancer, Head and Neck Cancer, Hematologic Malignancy, Lung Cancer, Melanoma, Molecular Oncology, Neurooncology, Palliative and Supportive Care, Pediatric Oncology, Surgical Oncology, Translational Oncology, and Urologic Oncology.
