It generally is accepted that earlier diagnosis of sarcoma is associated with a better disease-free survival. Because the legal community is convinced this is true, a delay in cancer diagnosis is a frequent source of medical malpractice lawsuits. We asked whether symptom duration before diagnosis affected sarcoma outcome. We compiled prospective data from 624 consecutive patients with sarcoma treated from 1992 to 2003. The data included length of symptoms before diagnosis, tumor size and grade, presence of metastatic disease at diagnosis, anatomic location, disease-free survival, overall survival, and local recurrence. Length of symptoms did not predict presence of metastatic disease at diagnosis, survival, or disease-free survival. We found no correlation between the length of a patient's symptoms and the tumor size or anatomic site of disease (axial, proximal, and distal). Tumors were larger at diagnosis in axial and proximal locations than in more peripheral locations, despite no difference in length of symptoms before diagnosis. Patients with sarcoma with long-standing symptoms did not have a worse prognosis than those with a shorter length of symptoms before diagnosis in terms of disease-free survival, overall survival, and presence of metastatic disease at diagnosis.
一般认为,肉瘤的早期诊断与更好的无病生存率相关。由于法律界确信这一点,癌症诊断延迟是医疗事故诉讼的常见原因。我们询问了诊断前症状持续时间是否会影响肉瘤的预后。我们汇总了1992年至2003年连续治疗的624例肉瘤患者的前瞻性数据。数据包括诊断前症状持续时间、肿瘤大小和分级、诊断时转移疾病的存在情况、解剖位置、无病生存率、总生存率和局部复发情况。症状持续时间并不能预测诊断时转移疾病的存在、生存率或无病生存率。我们发现患者症状持续时间与肿瘤大小或疾病的解剖部位(轴向、近端和远端)之间没有相关性。尽管诊断前症状持续时间没有差异,但轴向和近端部位的肿瘤在诊断时比更外周部位的肿瘤更大。就无病生存率、总生存率和诊断时转移疾病的存在情况而言, 有长期症状的肉瘤患者的预后并不比诊断前症状持续时间较短的患者差。
