The aim of this study was to display the cancer-specific and overall survival of patients with primary and metastatic malignancies of the parotid gland. In this retrospective study all patients with primary parotid malignancy and metastatic cutaneous squamous cell carcinoma (cSCC) of the parotid gland treated surgically with curative intent at a tertiary care institution were included. Patients were followed with regards to their oncologic outcome for a minimum of two years. Management approaches, overall, and cancer-specific survival were compared between patients with primary and secondary parotid gland carcinomas. Ninety-four patients (43 patients with primary parotid malignancy; 51 patients with metastatic cSCC of the parotid gland) were included. Patients with metastatic cSCC were older (p = 0.001) and more frequently male (p = 0.002). Adjuvant therapy (p = 0.001) and neck dissection (p = 0.009) were more frequently performed among patients with metastatic cSCC of the parotid gland than among those with primary parotid malignancy. Mean follow-up was 50 (95% CI: 40-65) months. Five-year cancer-specific survival was 87.3% among patients with primary parotid malignancies and 54.5% among patients with metastatic cSCC (p = 0.006). Cancer-specific survival of patients with metastatic cSCC of the parotid gland is still low. An earlier diagnosis of parotid metastases of cSCC may potentially lead to a better prognosis.
本研究旨在展示原发和转移性腮腺恶性肿瘤患者的癌症特异性和总体生存率。在这项回顾性研究中,所有在三级医疗机构接受根治性手术治疗的原发腮腺恶性肿瘤和转移性腮腺皮肤鳞状细胞癌(cSCC)患者均被纳入研究。对患者进行了至少两年的肿瘤学随访,以评估其肿瘤转归。比较了原发和继发腮腺癌患者的治疗方法、总体生存率和癌症特异性生存率。共纳入 94 例患者(43 例原发腮腺恶性肿瘤患者;51 例转移性腮腺 cSCC 患者)。转移性 cSCC 患者年龄更大(p=0.001),且男性比例更高(p=0.002)。与原发腮腺恶性肿瘤患者相比,转移性腮腺 cSCC 患者更常接受辅助治疗(p=0.001)和颈部清扫术(p=0.009)。中位随访时间为 50 个月(95%CI:40-65)。原发腮腺恶性肿瘤患者的 5 年癌症特异性生存率为 87.3%,转移性腮腺 cSCC 患者为 54.5%(p=0.006)。转移性腮腺 cSCC 患者的癌症特异性生存率仍然较低。早期诊断腮腺 cSCC 转移可能会带来更好的预后。
