Metachronous prostate and colon adenocarcinomas

Area of Science:

• Oncology
• Gastroenterology
• Urology

Background:

• Multiple primary malignancies are uncommon in clinical practice.
• Prostate cancer and colon cancer represent distinct primary diagnoses.

Observation:

• A patient with untreated prostate adenocarcinoma was diagnosed with colon adenocarcinoma seven months later.
• The patient underwent surgical resection for the colon cancer.

Findings:

• The patient recovered well following a right extended hemicolectomy.
• Adjuvant chemotherapy and hormonal therapy are planned for the colon cancer.

Implications:

• Managing synchronous or metachronous multiple primary tumors presents unique clinical dilemmas.
• Treatment decisions must carefully weigh the status of active primary tumors and patient factors.
