Immunologic patterns of regional lymph nodes in squamous cell carcinoma of the floor of the mouth

During 1996–2015 years, 53 patients with stage locally-advanced squamous cell carcinoma of the pharynx with stage N3 were treated in N. N. Blokhin National Research Center of Oncology. Depending on the treatment method, patients were divided into 2 groups: concurrent (n = 26) and induction (n = 27) chemoradiotherapy. Concurrent chemoradiotherapy (option 1) was given using: cisplatin 100 mg/m2 – every 3 weeks, or carboplatin 1.5 AUC weekly, or cisplatin 100 mg/m2 with 5-fluorouracil 1000 mg/m2 every 24 hours, in continuous infusion for 96 hours (PF). Induction chemotherapy (option 2) was performed in 2 modes: TPF (docetaxel, cisplatin, 5-fluorouracil) or PF (cisplatin, 5-fluorouracil). Radiation therapy was performed on a linear accelerator for 2 Gy daily up to SD 68–70 Gy for the primary tumor and 66 Gy for the affected lymph nodes. According to the results of our retrospective study, the 3 year overall and relapse-free survival rate depending on the chemoradiotherapy option was 37 and 32 % (option 1), 62 and 56 % (option 2). A promising option for chemoradiotherapy of locally advanced squamous cell carcinoma of the pharynx is induction chemoradiotherapy.

Significant Difference

BACKGROUND: Squamous cell carcinoma (SCC) of the lower lip is a relatively rare carcinoma, with the incidence of 1 to 2%, but it is the most common carcinoma in the oral cavity accounting for 25-30% of all malignant oral tumours. AIM: This study aimed to determine the role of neovascularisation in the process of tumour progression. METHODS: We analysed the surgical specimens obtained from 60 patients with squamous cell carcinoma (SCC) of the lower lip. The examined group consisted of 45 specimens of patients without metastasis and 15 specimens of patients with metastasis in the regional lymph nodes. Histopathological slides were immunohistochemically stained with an antibody against CD34 and by hematoxylin & eosin staining for routine histopathological examination. RESULTS: The results obtained showed a statistically significant difference in the density of neovascularisation between groups of the SCC with different grade of differentiation (Kruskal-Wallis test: H (2, N = 60) = 30.0943, p = 0.00001). Statistical analysis also showed a significant difference in the density of vascularisation of lower lip SCC between patients without metastasis and patients with neck metastasis (Mann-Whitney U test, p = 0.000198). Applying Pearson’s chi-square test, we found a highly significant statistical difference in grade of SCC differentiation in patients with and without neck metastasis (p = 0.0000). CONCLUSION: In conclusion, the density of neoangiogenesis is increased in tumours with poorer differentiation and in patients with neck metastasis. So, the density of neovascularisation of the primary lip SCC may predict the tumour progression.
