This study was undertaken to gain insight into the distinctive features of squamous cell carcinoma of the lip (LSCC) and oral cavity (OCSCC).
A total of 37 cases of LSCC and 54 of OCSCC were compared regarding clinical and microscopic findings.
Predominance of head and neck TNM stages (HNTNM) T1-T2 in LSCC and T3-T4 in OCSCC was observed. A significant percentage (33.3%) of patients with OCSCC at HNTNM T1-T2 presented cervical lymph node metastasis and 18.75% died, whereas lymph node metastasis was absent and no patient died with LSCC at HNTNM T1-T2. LSCC demonstrated a higher number of cases with intense peritumoral inflammatory infiltrate compared with OCSCC. The analysis of the proliferative index demonstrated a significantly higher percentage of PCNA+ and Ki-67+ cells in OCSCC compared with LSCC.
Our results suggest that OCSCC and LSCC demonstrate distinct clinical and microscopic characteristics that reflect different biologic behavior and prognosis.
开展本研究以深入了解唇鳞状细胞癌（LSCC）和口腔鳞状细胞癌（OCSCC）的独特特征。
对37例LSCC和54例OCSCC的临床及显微镜检查结果进行比较。
观察到LSCC中头颈部TNM分期（HNTNM）以T1 - T2为主，而OCSCC中以T3 - T4为主。在HNTNM T1 - T2期的OCSCC患者中，有相当比例（33.3%）出现颈部淋巴结转移，18.75%的患者死亡；而在HNTNM T1 - T2期的LSCC患者中未出现淋巴结转移，也无患者死亡。与OCSCC相比，LSCC中肿瘤周围有强烈炎性浸润的病例数更多。增殖指数分析显示，与LSCC相比，OCSCC中PCNA +和Ki - 67 +细胞的比例显著更高。
我们的结果表明，OCSCC和LSCC表现出不同的临床和显微镜特征，反映了不同的生物学行为和预后。
