Surgical treatment for thyroid carcinoma: retrospective study with 811 patients in a Brazilian tertiary hospital

Abstract

Objective: The aim of the present study was to describe the epidemiologic data, histological type, treatment and follow-up of the 811 patients treated for thyroid cancer in Instituto do Câncer do Estado de São Paulo (ICESP) over 5 years. Materials and methods: Retrospective analyses of electronic chart information. Results: There were 679 cases (83.7%) of papillary thyroid cancer, 61 (7.5%) of follicular carcinoma, 54 (6.7%) of medullary carcinoma, 11 (1.4%) of poorly differentiated carcinoma and 6 of anaplastic carcinoma (0.7%). The majority of patients were female (82.2%), and the mean age was 50.5 ± 15 years. Two hundred forty-two patients had disease persistence or recurrence. At the last follow-up, 629 (77.6%) patients were alive and disease free, 141 (17.4%) were alive with disease, and 41 (5.1%) were deceased, with 37 deaths related to thyroid cancer. Conclusion: This study was able to outline the profile, disease type and evolution of patients treated for thyroid cancer at a single tertiary hospital. Arch Endocrinol Metab. 2016;60(5):472-8

Thyroid Surgeries in a Single Centre, 2010 - 2014

“…Similarly, it is ranked the third most common among Kuwaiti women and second most common among Saudi women 12 . The female predominance observed in this study is similar to those of the previous studies from KSA, UAE, Yemen, Kuwait, Poland, Togo, Turkey, and Brazil 7,9,10,[13][14][15][16][17] . In contrast, thyroid cancer is the 16th most common among females in Ireland 18 .…”

“…Papillary and follicular cancer make up the majority (>90%) of all thyroid cancers worldwide 1 . Papillary thyroid cancer constituted the majority of diagnosed thyroid cancer with variations in relative frequencies in reported studies from KSA, Poland, India, Brazil, Turkey, Germany, Italy, China and Philippines 2,7,9,10,13,14,[19][20][21][22][23][24] . Even in Africa where follicular thyroid cancer was predominant over papillary in the 1980s, a more frequent occurrence of papillary thyroid cancer was reported by Ogbera and Kuku 25 .…”

Incidental diagnosis and surgery outcomes of thyroid cancer in Ecuador

“…One-third of patients had either surgical adverse event or a post-surgical Tg value that suggested residual benign or malignant thyroid tissue. The high frequencies of poor surgical outcomes suggest a lack of surgical thyroid cancer expertise 38,39 . In Ecuador, there are no residency programs dedicated to training surgeons about the treatment of TC.…”

Papillary thyroid carcinoma coexists with undifferentiated carcinoma & A case report and review of literature

“…PTC, as differentiated thyroid carcinoma (DTC), has good prognosis but 5% of the patients already have distant metastasis at the diagnosis [3]. The incidence of PTC was about 83.7% in thyroid malignancies and increased 5.2% per year, according to the epidemiologic data by Cavalheiro BG et al [4] And UTC is a rare and extremely aggressive malignancy, with the median survival of less than 6 months due to rapid progression and resistance to multimodal therapies [5]. However, coexistence of PTC with UTC is extremely rare.…”
