Purpose：To study occult neck metastasis and the effects of salvage treatment. Methods：18 patients with stage Ⅰ or Ⅱ oral tongue squamous carcinomas had not received previous treatment. The tongue primary was excised via the transoral route and the neck was observed closely during follow-up.Results：The incidence of occult neck matastasis was 44% (7/16). The salvage rate after appearance of nodal matastasis was 27%(3/7).Conclusions：In oral tongue cancers, elective neck treatment should be considered regardless of a small primary and negative neck examination because of the high incidence of occult nodal matastasis and the poor outcome after salvage treatment.

Objective　Tongue cancer shows an increasing frequency in young individuals. There is controversy concerning the clinical course and outcome for oral tongue cancer in young patients.Methods　A retrospective review of 23 patients under 40 years of age with squamous cell carcinoma of tongue was performed. These patients were matched to an older patients group. The 5-year disease-free survival, rates of local, regional and distant recurrence were determined for both groups. Results　The 5-year disease-free survival for the young patients was 68 % versus 74 % in the older group (P＞0.05). 7/23 (30 %) of young patients recurred locally versus 3/23 (14 %) of the older patients (P＞0.05). 6/23 (26 %) of young patients recurred regionally versus 4/23 (18 %) patients in the older group (P＞0.05). The metastatic rates were similar in both groups.Conclusion　In this series, young patients with sguamous cell carcinoma of the oral tongue had a higher locolregional recurrence rate than did older patients. This dose not mean that there is a survival difference.

Background and purpose: The aim of this study was to determine the necessity of central compartment neck dissection in laryngeal cancer.Study Design: Retrospective study at a tertiary referral medical center. Methods:Patients with laryngeal squamous cell cancer who underwent neck dissection were evaluated, and a retrospective analysis of clinicopathologic factors and follow-up data were performed. Results: One hundred and eighteen patients from 1999 to 2009 were enrolled. There were 11.9% central compartment lymph node metastasis in all patients, including the 10 patients with central compartment lymph node metastasis in 34 patients underwent compartment neck dissection and 4 patients do not underwent compartment neck dissection but had central neck recurrence in the follow up time. Subglottic or pyriform extension were risk factors in central compartment lymph node metastasis and central neck recurrence (P=0.002). Central compartment lymph node metastasis had closed relationship with levelⅣmetastasis (P<0.001), extracapsular extension (P=0.001), vascular extension (P=0.015) and poor local control rates (P=0.035) respectively. Patients who were positive for lateral neck lymph node metastasis had poor disease-free survival rate (P=0.014) and poor local control rates (P=0.025), and supraglottic cancer had a trend to metastases to levelⅡ(P=0.044). Conclusion:Central compartment neck dissection might be considered a potential therapeutic approach for patients with laryngeal cancer.

Objective To evaluate traditional surgical treatment, intraluminal strategy and hybrid operation on revascularization of atherosclerosis obliterans (ASO) of the lower extremity. Methods Clinical data of 197 ASO cases receiving revascularization from January, 1998 to December, 2008 were retrospectively analyzed. Seventy-seven cases underwent surgical treatment, 82 cases received intraluminal therapy, and 38 cases were treated by hybrid operation. The indications, clinical effect, complication and perioperational mortality of these three strategies were evaluated. Results 71% patients (164 cases) were followed up from 2 to 112 months. Surgical and intraluminal method had no statistical difference on long-term patency of aortic-iliac and femoral-popliteal artery (57% vs. 51%;48% vs. 42%). Hybrid procedure led to higher patency on multi-level lesion and concurrent thrombosis. The complications after surgery was higher than intraluminal on aortic- iliac and femoral-popliteal artery (31% vs. 12%;31% vs. 11%), and higher than intraluminal and hybrid on multi-level lesion (36% vs. 12% vs. 15%). The perioperative mortality of surgical group was 1.5% and 2.0% on aortic-iliac and multilevel lesion and 0% on other site;and that of intraluminal and hybrid procedure was 0%. Conclusion For aortic-iliac and femoral-popliteal artery revascularization, surgery was preferred in cases of long occlusive lesion and intervention was preferred for cases with short non-occlusive lesion. Hybrid procedure was the best for multi-level and concurrent thrombosis.

OBJECTIVETo investigate the clinical features of familial papillary thyroid carcinoma (FPTC) and the criteria for its diagnosis and surgical treatment.

METHODSOne hundred and forty-five patients with PTC were investigated randomly between January 1999 and November 2001, and 17 of them were from 7 families. Of the 17 patients, 14 were operated on at this hospital, and 3 were operated elsewhere. The specimens from the 17 patients were confirmed pathologically. They accounted for 9.3% (14/145) of all PTC patients.

RESULTSThe patients were aged from 30 to 74 years (mean 45 years). The diameter of original focuses ranged from 0.8 to 2.8 cm (mean diameter 1.7 cm). Of the 17 patients with PTC, 8 (47.5%) had bilateral carcinoma. In 3 families, 3 patients suffered from PTC (42.8%). In 4 families, other members suffered from benign thyroid tumor or non-tumorous thyroid disease. Among the 17 patients, 10 had nodular goiters. Thyroidectomy, unilateral thyroidectomy plus isthmusectomy, and combined radical operation were performed in 8, 9, 14 patients, respectively. Early metastatic spread to local regional lymph nodes was noted in 14 patients (82.3% or 14/17).

CONCLUSIONSIn this study, a FPTC rate of 10% was found. Almost 50% of FPTC patients had bilateral carcinoma. The frequency of metastatic spread to local-regional lymph nodes was high. Follow-up survey of family members should be performed in a long period of time.

Objective To study the cotransfection mB7-1 and mCD1D gene into pancreatic cancer cells of rats and to observe its anti-tmor responses.Methods Recombinant retroviral vectors expressing mB7-1and mCD1D gene were packaged into GP2-293 cell lines and transfected.The expressions of mB7-1 and mCD1D were detected with PCR and Western blot.The positive cells of mB7-1 and mCD1D were used to induce the anti-tumor immunity in vitro.Results Anti-tumor immunity was induced after B7-1 and CD1D positive cells were coinoculated in syngeneic mice.Furthermore,the growth of tumor was inhibited.Conclusions Cotransfection of B7-1 and CD1D could induce anti-tumor effect.This study provide a foundation for the application of B7-1 and CD1D gene therapy in tumor.

Objective: To analyze the risk factors for metastasis of lymph nodes between sternocleidomastoid and sternohyoid muscle (LNSS) in papillary thyroid cancer (PTC). Methods: Papillary thyroid cancer patients with clinically positive lateral lymph node metastasis (cN1) who underwent surgery including LNSS dissection between May 1, 2013 and May 31, 2016 at the Department of Head and Neck Surgery, Fudan University Shanghai Cancer Center were retrospectively studied. Logistic regression analysis was performed to evaluate possible clinicopathological factors related to LNSS metastasis. Results: In 85 patients, 54 patients (63.5%) showed LNSS in their surgical specimen, and 20 patients (23.5%) had pathologically positive LNSS metastasis. Patients with LNSS showed preoperatively higher levels of serum thyroid stimulating hormone (TSH) and thyroid peroxidase antibody (TPO-Ab) compared to patients only with fibrofatty tissues between sternocleidomastoid and sternohyoid muscle (P<0.05), and they also displayed a higher proportion of multifocality in ipsilateral thyroid lobe (P<0.05). Multi-factor analysis indicated that LNSS metastasis was correlated with original tumor size (OR=1.819, 95%CI 1.050-3.850, P=0.002) and Level Ⅳ lymph node metastasis (OR=2.190, 95%CI 1.132-2.334, P=0.005). Furthermore, the number of positive LNSS was tightly correlated to that of level Ⅳ lymph node metastasis(P<0.05). Conclusion LNSS metastasis is occult but not quite rare in PTC. Patients with extensive lymph node metastasis in Level Ⅳhave a higher risk for metastasis of LNSS.
