ABSTRACT
Objective@#To summarize the clinical anatomical features and surgical technique of the submental artery perforator flap (SMAPF), and to evaluate the outcome and value of the flap for oral cavity reconstruction after cancer ablation.@*Methods@#A total of 56 patients with oral cancer were included in this study. The modified SMAPF excluded the anterior belly of the digastric muscle and submental fatty tissue. The primary sites of malignancy were buccal mucosa (n=24), tongue (n=21), mandibular gingiva (n=6), mouth floor (n=3), soft palate (n=2).@*Results@#The flap size varied from 3 cm×5 cm to 5 cm×12 cm. Four flaps presented mild venous congestion, which was salvaged with conservative measures such as acupuncture and blood letting. Overall flap survival rate was 100%. The SMAPF with septocutaneous perforator was used in 49 cases and with musculocutaneous perforator in seven cases. External jugular vein and internal jugular vein provides venous drainage were applied in half cases respectively. All the patients showed a good recovery of tongue mobility and mouth opening with a follow-up of 3-41 months. Local recurrence was detected in one patient 4 months after operation.@*Conclusions@#The SMAPF is a reliable flap for oral cavity reconstruction with outstanding functional and aesthetic outcomes.
ABSTRACT
Objective To investigate the role and feasibility of tumor necrosis factor(TNF) and/or interferon(IFN) in comprehensive treatment of tongue cancer in vitro and explore a new pathway about clinical treatment of tongue cancer . Methods The role of TNF and/or IFN in tongue cancer cell line (Tca 8113) growth and their effect on chemotherapy & radiotherapy of Tca8113 were detected by MTT-assay in vitro.Results ⑴There was a obvious volume-effect relationship in inhibitory effect of TNF or IFN on tongue cancer cell line; when TNF combind with IFN,their cytotoxity enhanced significantly than only TNF or IFN. ⑵TNF & IFN have enhanced the cytotoxities of low dose DDP,PLM and Taxol on Tca 8113 cell line.⑶TNF obviously enhanced the inhibition rate of radiotherapy(dosage:2～8Gy)on Tac 8113 cell line(P
ABSTRACT
Objective To analyze the relationship between the chemotherapeutic efficacy and VEGF expression in the patients with oral squamous cell carcinoma. Methods 51 cases with oral squamous cell carcinoma who received preoperative chemotherapy of a total 80mg pingyangmycin were enrolled in this study. The relationship among the chemotherapeutic effect, VEGF expression, fever, and the duration of fever was analyzed using linear correlation, stepwise regression and student t-test. Results VEGF expression in the cancer cells of 92.1%(47/51) patients decreased after preoperative chemotherapy, and the decreased expression of VEGF was not significantly correlated with chemotherapentic efficacy. But the chemotherapeutic effect was closely related with fever degree in the early stage of chemotherapy. Conclusion There was no significant relationship between chemotherapeutic effects and VEGF expression in oral squamous cell carcinoma. Fever in early stage of chemotherapy may serve as an index for evaluating the patient prognosis.
