Secondary involvement of the gastrointestinal tract by malignancies is encountered frequently. It usually reflects a poor prognosis because it is often multicentric and associated with metastases in other organs. Any therapy is usually palliative. Because of this, conventional barium studies or CT is sufficient for diagnosis and can obviate further studies.
恶性肿瘤继发累及胃肠道很常见。这通常预示着预后不良，因为它往往是多中心的，且与其他器官的转移有关。任何治疗通常都是姑息性的。因此，传统的钡剂造影或CT足以用于诊断，无需进一步检查。
