Occult primary malignancies (OPMs) are the eighth most common cancer in the United States. Generally, the prognosis is poor, with survival usually lasting two to four months from the time of diagnosis. The primary tumor will never be found in more than half of the patients, even after an exhaustive diagnostic workup and eventual autopsy. The majority of these tumors are metastatic at the time of diagnosis; therefore, therapy is palliative. Nursing implications include providing symptom management, psychological support, and patient education.
隐匿性原发性恶性肿瘤（OPM）是美国第八大常见癌症。一般来说，预后较差，从诊断时起生存期通常为两到四个月。即使经过详尽的诊断检查并最终进行尸检，超过半数的患者也始终无法找到原发性肿瘤。这些肿瘤中的大多数在诊断时已发生转移；因此，治疗是姑息性的。护理工作包括症状管理、心理支持和患者教育。
