Endobronchial metastasis from prostate cancer

Area of Science:

• Oncology
• Pulmonology
• Pathology

Background:

• Prostate adenocarcinoma can metastasize to unusual sites.
• Endobronchial metastasis is a rare manifestation of prostate cancer.
• Androgen blockade is a standard treatment for advanced prostate cancer.

Observation:

• A patient with a history of prostate cancer presented with dyspnea and dry cough.
• Flexible bronchoscopy revealed multiple polypoid lesions in the tracheobronchial tree.
• Immunohistochemical analysis of biopsy specimens confirmed metastatic prostate adenocarcinoma.

Findings:

• This is the first reported case of endobronchial metastasis from androgen-refractory prostate cancer without extrathoracic spread.
• The patient received combination chemotherapy (paclitaxel, estramustine phosphate, carboplatin).
• Treatment resulted in suppression of respiratory symptoms.

Implications:

• This case underscores the importance of considering unusual metastatic sites in prostate cancer patients.
• A multidisciplinary approach involving pulmonologists, urologists, pathologists, and oncologists is crucial for managing endobronchial metastases.
• Further research may explore the mechanisms and optimal management of such rare presentations.
