Background: Total fat intake may be associated with increased risk of breast cancer, and fish oil has been suggested as a protection factor to breast cancer. But the effect of vegetable oils is inconclusive. We aimed to investigate the association with high vegetable oils consumption and breast cancer risk, and evaluated their dose-response relationship. Design: We systematically searched the MEDLINE, EMBASE, Cochrane databases, and CNKI updated to December 2014, and identified all observational studies providing quantitative estimates between breast cancer risk and different vegetable oils consumption. Fixed or random effect models were used to estimate summary odds ratios for the highest vs. lowest intake, and dose-response relationship was assessed by restricted cubic spline model and generalized least-squares trend (GLST) model. Results: Five prospective cohort studies and 11 retrospective case-control studies, involving 11,161 breast cancer events from more than 150,000 females, met the inclusion criteria. Compared with the lowest vegetable oils consumption, higher intake didn't increased the risk of breast cancer with pooled OR of 0.88 (95% CIs:0.77-1.01), and the result from dose-response analyses didn't show a significant positive or negative trend on the breast cancer risk for each 10g vegetable oil/day increment (OR=0.98, 95% CIs: 0.95-1.01). In the subgroup analyses, the oils might impact on females with different strata of BMI. Higher olive oil intake showed a protective effect against breast cancer with OR of 0.74 (95% CIs: 0.60-0.92), which was not significant among the three cohort studies. Conclusions: This meta-analyses suggested that higher intake of vegetable oils is not associated with the higher risk of breast cancer. Olive oil might be a protective factor for the cancer occurrence among case-control studies and from the whole. Recall bias and imbalance in study location and vegetable oils subtypes shouldn't be ignored. More prospective cohort studies are required to confirm the interaction of the impact of vegetable oils on different population and various cancer characteristic, and further investigate the relationship between different subtype oils and breast cancer.
Purpose : It has been generally accepted that lobectomy is a standard surgical procedure in treatment of benign thyroid nodules. However lobectomy may cause postoperative hypothyroidism. Most of surgeons believe that nodulectomy has its limitation in treatment of thyroid nodules due to recurrence of nodules and presence of cancer. The current study attempts to determine whether nodulectomy is justified in aspects of preservation of thyroid function, risk of recurrence and complications. Methods: Data was collected retrospectively on 74 patients undergoing thyroidectomy(single nodulectomy, n=43;bilateral nodulectomies, n=9;lobectomy with nodulectomy, n=22) for benign thyroid nodules from 1999 to 2004. All patients were evaluated for complication, postoperative thyroid function, and recurrence of benign nodule and cancer were followed by regular ultrasonographic examination for 2-6 years. Results : The pathologic results of 74 patients were nodular hyperplasia(55 patients), Hashimoto's thyroiditis(8 patients), follicular adenoma(7 patients) and papillary carcinoma(4 patients). Average operation time was 30 minutes from skin incision to specimen out. In postoperative follow-up of 70 patients, six cases(8.5%) became mild hypothyroid, and ultrasonographically detected micronodule was also six cases(8.5%). There were no other complications. Conclusion : Thyroid nodulectomy appears to have advantages of relatively few complication and simple procedure with no access to laryngeal nerves. Therefore, it may be one of treatment options in selected cases of benign thyroid nodules.
Thyroid carcinoma is relatively rare in children. Eight cases of thyroid carcinoma were among 18 patients operated upon for thyroid tumors at Pediatric Surgery, Asan Medical Center in 11 years' period between 1989 and 2000. Five patients were boys and three were girls. The age distribution ranged from 10 to 14 years with a median age of 11.6 years. We studied clinical presentations, diagnostic workup, pathology, treatment, and follow-up (recurrence, mortality, and survival). All patients presented with anterior neck mass but one with multiple cervical lymph nodes enlargement. Familial history of thyroid cancer was seen in one case. All patients had a cold nodule by 1-131 thyroid scan. Fine needle aspiration (FNA) biopsy was performed in all patients. The right lobe was involved in four patients and the left lobe in two. Two had both lobes involvement. Pathologically, six cases were papillary carcinoma, one was follicular carcinoma, and one insular carcinoma. Four patients underwent unilateral lobectomy and isthmectomy. Total thyroidectomy was performed in three patients. The insular carcinoma case was preoperatively diagnosed as follicular neoplasm by FNA. After confirmation of the pathology by initial right thyroid lobectomy, total thyroidectomy was subsequently done. Cervical lymph node metastases were presented in three cases (37.5%), and lung metastasis in two cases (25%). Three patients received postoperative I-131 ablation. After a median follow-up of 53 months, all patients were alive without evidence of recurrence. In conclusion, thyroid carcinoma in children is frequently associated with lymph nodes involvement and distant metastasis, however, the prognosis is relatively good.
Objectives: With the recent advances and increasing use of imaging techniques in examination of the neck, the incidence of incidentally discovered thyroid carcinoma has been increasing. This study was carried out to evaluate the clinicopathologic characteristics of incidental thyroid carcinomas and to find optimal therapeutic strategies for these lesions. Materials & Methods: From Jan. 1988 to Aug. 1998, 1,053 patients were operated on for thyroid cancer, of whom 127(12.1%) had incidentally discovered thyroid cancers which were identified during routine health checkups(n=40), diagnostic procedures for unrelated medical conditions(n=39) and mass screening for thyroid cancer(n=48). The preoperative diagnosis was obtained by ultrasound-guided FNAB and the extent of surgery was determined based on frozen section examinations, as well as prognostic factors and gross findings at the time of surgery. Results: There were 6 men and 121 women with a mean age of 45.9 years. Histopathological diagnosis included papillary carcinomas(n=1l9), follicular carcinomas(n=6), poorly differentiated carcinoma(n=l) and medullary carcinoma(n=1). Thirty patients(23.6%) had multifocallesions. The mean diameter of the tumors was 1.1 cm(0.2-3.4 cm). Capsular invasions were found in 53 patients(41.7%) and nodal metastases in 41(32.3%). The surgical procedures used were: 90 less-than total thyroidectomies and 37 total thyroidectomies with central neck node dissection. Lateral neck dissection was added in 5 patients. According to TNM staging, 79 patients(63.2%) were at stage I, 15(12.0%) at stage II, 31(24.8%) at stage III and 0(0.0%) at stage IV. By AMES scoring system, 102 patients(81.6%) were in the low-risk group and 23(18.4%) in the high-risk group. And by MACIS scoring system, 103(86.6%) of 119 papillary thyroid cancer patients were less than 6. Conclusions: The clinicopathological characteristics of incidentally discovered thyroid carcinomas are similar to ordinary thyroid carcinomas. The treatment of choice should be individualized based on the particular clinical situation encountered, as in ordinary thyroid carcinomas.
Objective : This study was aimed to obtain epidemiological information of cancer patients treated with Oriental medicine. Methods :The medical records of 899 cancer patients treated at the East-West Cancer Center of Dunsan Oriental Hospital from January to December 2008 were analyzed. Careful investigations were done by categorizing these patients by their sex, origin, stage, treatment duration, conventional treatment type, etc. Results : 61.7% of the patients had stage IV tumor. 53.1% of patients visited Oriental hospital for combination treatment with conventional medicine. In the tumor origin, lung cancer showed the largest proportion (21.6%). Of the two genders, lung cancer was the most frequent cause (31%) in male patients, and breast cancer in females (21.2%). In inpatients, thyroid cancer resulted in the highest percentage (24.0%). Lung, colon, stomach cancer patients were mostly in stage III or IV. Thyroid cancer patients were mostly in stage I. Conclusions : This study presented the characteristics of cancer patients treated by Oriental medicine. Based on this study, further advanced study of Oriental medical cancer treatments is needed.

Ultrasound-guided fine needle aspiration biopsy (FNAB) is a costly diagnostic item with a low yield in identifying the tiny proportion of nodules that actually represent malignant disease. Our aim through this study was to obtain an ultrasound (US) score for selecting subcentimeter-sized thyroid nodules requiring FNAB in eastern China. Some 248 patients for a total of 270 thyroid nodules less than 1 cm in diameter underwent FNAB and subsequent surgery from January 2006 to March 2012 at our hospital. The clinicopathological and US data from all the nodules were analyzed retrospectively. An US score was developed on the basis of independent predictive factors for malignancy. Irregular shape, hypoechogenicity, no well-defined margin, presence of calcifications and ratio between antero-posterior and transversal diameters (AP/TR) ${\geq}1$ were independent predictive factors for malignancy on logistic regression analysis. US score were statistically significant, with ${\leq}2$ favoring benignancy with an 80.3% sensitivity and a 72.7% specificity. US score is useful for differentiating between malignant and benign subcentimeter-sized thyroid nodules. We suggest FNAB for nodules when the US score is higher than 2.
Korea Central Cancer Registry reported in 2011 that the prevalence rate of thyroid cancer was about 19.6% (the highest) in both men and women. The ratio of thyroid cancer, among cancers that women suffer from, was about 31.1%, the highest among female cancers and about five times more than men. Regarding the incidence of thyroid cancer by age group, the crude rate was highest in women and men aged 15~34. From these figures it can be inferred that there is a greater relationship between thyroid cancer and hormones compared with other cancers. Therefore, young women aged 20~25, even if they are in full health, should undergo a medical examination. This study is aimed at examining changes in thyroid gland detected through self evaluation tests and the analysis of ultrasound screening images in persons aged 20~25. According to the study, 213 persons (about 46.6%) out of 457 people who took part in the study had abnormal echo patterns. With regard to women's abnormal patterns, about 73.4% of them were found to have calcified cystic, 11.8% diffuse-type low-echo and 7.3% cystic echo. With regard to male participants, about 61.1% were found to have calcified cystic, followed by 19.4% with the size of the isthmus increased and 13.9% with diffuse-type low-echo. According to the outcomes of an analysis regarding self-testing for hyperthyroidism, the average points of participants who were found to have abnormal echo patterns in ultrasound tests were 6.85 and the figure was 5.88 in persons with normal patterns. The figure was about 15% higher in abnormal respondents.
To evaluate the clinical utility of Tc-99m MIBI scan in the detection of residual thyroid tissue or metastatic lesion in postoperative thyroid cancer patients, we compared Tc-99m MIBI scan with I-131 diagnostic and therapeutic scan in 30 postoperative well-differentiated thyroid cancer patients. Thyroglobulin levels of both on and off thyroid hormone medication and antithyroglobulin antibody were tested [Tg(on), Tg(off)]. Positive rates for I-131 diagnostic and Tc-99m MIBI scan were 81% and 68% respectively. Concordance between I-131 diagnostic and Tc-99m MIBI scan was observed in 15 cases; 12 positive and 3 negative respectively. Among the 6 cases with negative I-131 diagnostic scan and positive Tc-99m MIBI scan, 4 were Positive in the therapeutic I-131 scan We concluded that Tc-99m MIBI scan maybe a useful complementary modality to the currently established method of I-131 scan and serum thyroglobulin level in the detection of recurrent or metastatic thyroid cancer, especially in the case of negative I-131 diagnostic scan.
The purpose of this study was to examine the anxiety, depression, uncertainty, social support, and QoL and to identify the factors influencing QoL in women with thyroid cancer. A descriptive survey was performed from April to October in 2014 with self-reporting questionnaires for depression, uncertainty, social support, and QoL. Participants were 106 women with thyroid cancer who visited a outpatient department of endocrine surgery in a hospital. Data were analyzed using SPSS 22.0. As the results of this study, the mean scores of global QoL were moderate. Anxiety was significantly influenced physical functioning, emotional functioning, and social functioning. Uncertainty was significantly influenced physical functioning and cognitive functioning. Therefore, from the results of this study, nursing practice focused on anxiety and uncertainty relieving care for female thyroid cancer patients to improving QoL. And also, in order to understand the QoL of women with thyroid cancer, it is necessary to deeply understand the QoL through qualitative and quantitative research to determine the QoL by treatment period and treatment type.
