Clinical Scorecard: Gallbladder Mixed Adenoneuroendocrine Carcinoma: A Case Study and Review of Existing Literature

At a Glance

Key Highlights

• GB-MANEC is a rare and aggressive subtype of gallbladder cancer with poor prognosis.
• Diagnosis is primarily established through postoperative histopathology and immunohistochemistry.
• Surgical treatment, including radical resection, is the cornerstone of potentially curative treatment.
• Adjuvant chemotherapy with cisplatin, gemcitabine, etoposide, and trastuzumab was initiated post-surgery.
• The patient remained free of recurrence during 7 months of follow-up.

Guideline-Based Recommendations

Diagnosis

• Postoperative histopathological examination is essential for definitive diagnosis.

Management

• Radical surgical resection is recommended as the primary treatment approach.

Monitoring & Follow-up

• Long-term surveillance is necessary to define durable outcomes and monitor for recurrence.

Risks

• High aggressiveness and early metastasis are associated with GB-MANEC.

Patient & Prescribing Data

A 51-year-old female with non-specific abdominal complaints and anemia.

Adjuvant chemotherapy combined with targeted therapy was initiated postoperatively.

Clinical Best Practices

• Utilize a multidisciplinary approach for the management of GB-MANEC.
• Consider high-throughput sequencing for identifying genetic alterations in tumors.
