ABSTRACT
Objective:To explore the clinical value of surgical resection combined with 131Ⅰ therapy in the treatment of differentiated thyroid carcinoma(DTC)in the elderly. Methods:From January 2010 to December 2015, 168 elderly patients with DTC admitted to the general surgery department of our hospital were divided into the combined treatment group(n=97)and the surgery group(n=71). During the same period, 68 young and middle-aged patients with DTC were enrolled as the control group.The combined treatment and control groups were treated with total or subtotal thyroidectomy combined with 131Ⅰ therapy, while the surgery group received surgical resection only.An enzyme-linked immunosorbent assay(ELISA)was used to monitor the thyroglobulin(Tg)level of patients in the three groups before and 1 week after treatment and 1, 3, 6 months after treatment, and adverse reactions and clinical efficacy grading within 6 months after treatment were evaluated.Tumor recurrence and metastasis and patient survival in the three groups were followed up for 5 years. Results:After 1 month of treatment, serum Tg levels showed significant differences between the three groups( F=15.329, P=0.011), and Tg levels were lower in the control group than in the combined treatment and surgery groups[(30.47±6.97) μg/L vs.(47.13±7.34) μg/L, (46.12±6.55) μg/L, t=3.462 and 4.791, P=0.017 and 0.023)]. After 3 and 6 months of treatment, serum Tg levels still had significant differences between the three groups( F=22.641 and 34.182, P=0.000 and 0.000), and Tg levels were lower in the combined treatment and control groups than in the surgery group[(28.27±10.16) μg/L, (41.82±9.83) μg/L vs.(13.17±2.69), t=3.164 and 4.649, P=0.012 and 0.005; (11.16±5.43) μg/L, (28.67±9.19) μg/L vs.(1.45±0.28) μg/L, t=4.251 and 7.283, P=0.009 and 0.000)], and the control group had lower Tg levels than the combined treatment group( t=2.184 and 4.537, P=0.011 and 0.000). After 6 months of treatment, the incidences of myelosuppression(21.6%, 0.0% vs.11.8%, χ2=17.851, P=0.000)and gastrointestinal reaction(37.1%, 11.3% vs.27.9%, χ2=14.070, P=0.001)were higher in the combined treatment group than in the surgery and control groups.The control group had a higher rate of effectiveness than the other two groups(73.5% vs.62.9%, 31.0%, χ2=8.796 and 33.834, P=0.032 and 0.000)and the combined treatment group had a higher effectiveness rate than the surgery group, (62.9% vs.31.0%, χ2=18.825, P=0.000). During the follow-up, the tumor recurrence-free time and the survival time were better in the control group than in the other two groups( Log Rankχ2=30.335 and 20.628, P=0.000 and 0.000). Conclusions:Surgical resection combined with 131Ⅰ therapy can reduce local progression, recurrence and metastasis of DTC, but its clinical effectiveness is worse in elderly patients than in young and middle-aged patients.
ABSTRACT
Objective To analyze safety,effectiveness and prognosis of thyroidectomy in elderly patients with thyroid carcinoma.Methods A retrospective analysis was conducted in 142 elderly patients undergoing thyroidectomy for thyroid carcinoma in our hospital from October 2010 to March 2012.Clinical data of surgical treatment and postoperative pathogenetic conditions,including the incidence rate of operation complications,the rate of local relapse and distant metastasis,were analyzed.And the influencing factors on prognosis were also analyzed.Results Thyroidectomies for thyroid carcinoma were successfully completed in all patients.There were a total of 13 cases with postoperative complications,yielding a total complication rate of 9.15 ％,including an incision infection in 6 patients,hoarseness in 1 patient,and hypocalcemia in 6 patients.During median follow-up of 51 months,there were 12 patients dead,16 patients relapsing,and 6 patients with local and distant metastasis.Univariate analysis showed that age,lymph node metastasis,and clinical stage may affect the prognosis of elderly patients with thyroid cancer.Multivariate Cox Logistical analysis indicated that age,lymph node metastasis,and clinical stage were independent factors associated with the prognosis of elderly patients with thyroid carcinoma.Conclusions Age,lymph node metastasis,and clinical stage are independent factors for prognosis of elderly patients with thyroid carcinoma.
ABSTRACT
Purpose To evaluate imaging characteristics of normal and dynamic contrast enhanced multi-slice-spiral CT (MSCT) and 18F-FDG PET/CT in the patients with the mesenteric Castleman's disease (CD).Materials and Methods A retrospective analysis was made in 11 patients who were pathologically diagnosed CD and investigated their imaging characteristics of the MSCT and 18F-FDG PET/CT.Results 6 cases showed single lesion,all of them were round or oval.5 cases presented satellite lesions.The maximum diameter was (6.11 ± 1.45)cm.3 cases showed stippled or branch calcification,and 3 cases showed slightly patchy low density.11 cases had clear margins except 1 case.All cases showed the same strong lesion enhancement as that in aorta.9 cases showed significantly enhanced tumor blood vessels around the edge or shadow.The degree of 18F-FDG uptake increased in 11 cases,SUVmax was 3.1-5.7,and the average was (4.16 ± 0.86).Conclusion Multimodality imaging performances play an important role in the diagnosis of mesenteric CD.
