Patterns of differentiated thyroid cancer in Baluchistan Province of Pakistan: some initial observations

The incidence of thyroid cancer is increasing in several countries. The main objective of this retrospective study was to find and describe province-specific estimates of incidence in males and females by age groups for differentiated thyroid cancer (DTC). This study reports on 87 cases of DTC from Baluchistan province of Pakistan treated with post operative radioiodine at the Center for Nuclear Medicine and Radiotherapy (CENAR) Quetta from January 2003 to December 2009. The patient data has been collected from CENAR Quetta. Patients with DTC were confirmed by clinical examination, thyroid scintigraphy (Thyroid scan), blood tests (T3, T4, TSH) and histopathalogy tests and then treated with radioiodine. The Median age of the patients was 35.5 years (Range 12-70 years). The final histological diagnosis was papillary carcinoma in 71 (81.6 %) cases, follicular carcinoma in 6 (6.9%) cases while 10 (11.5%) cases presented with mixed papillary and follicular carcinoma. About 53 % cases were found in females with age 21-40 years. No strike predominance was observed in any age group for males. Four patients presented with recurrence while six patients showed metastasis in cervical lymph nodes. The small annual incidence did not follow any definite pattern. DTC has a small incidence in Baluchistan due to lack of education and health care facilities. The incidence of DTC is higher in females when compared with males as per this study. This preliminary study will provide an insight to incidence of DTC, its treatment facilities and future planning strategies in Baluchistan, Pakistan.     

Metastasis in differentiated thyroid carcinoma

Seventy patients of differentiated thyroid carcinoma (DTC) irrespective of age and sex were selected in ENT Department of Bangabandhu Sheikh Mujib Medical University, Dhaka Medical College Hospital and Rangpur Medical College Hospital who were admitted from March 2003 to March 2005. Female were more commonly affected (2.6:1) Papillary carcinoma was more common in 31-50 years of age and follicular carcinoma (ca) common in 41-50 years of age. Among the differentiated thyroid carcinoma papillary carcinoma found 77.15% and follicular ca. found 22.85%. Lymph node metastasis was more common in papillary (35%) than follicular carcinoma (12.5%). But distant metastasis was more common in follicular (12.5%) than papillary carcinoma (3.70). Maximum lymph node metastasis was found in level 3(55%), level 2(45%).     

Management of differentiated thyroid carcinoma

The study was done to determine the clinical, radiological and histopathological characteristics along with the management outcome of differentiated thyroid carcinoma. This Retrospective study included sixty patients with differentiated thyroid carcinoma presented to Department of Otolaryngology and Head-Neck Surgery at Dhaka Medical College Hospital and Apollo Hospitals Dhaka from June 2006 to December 2008. The data of each patient included age, sex, presenting symptoms and signs, provisional diagnosis, preoperative investigations, operation notes, histopathological examination and state at follow up. This study included 28 males and 32 females. The mean age was 42.7 years. Maximum patients presented at 4th decade. The commonest presentation was thyroid swelling followed by lateral neck swelling. Detailed clinical assessment before operative treatment has been done for all patients. Fifty five patients (91.66%) presented with single nodule. Distant metastasis was found in 2 cases. All patients underwent fine needle aspiration cytology which was conclusive in 38 patients (63.33%). All the sixty patients underwent surgical excision; either total thyroidectomy or completion thyroidectomy. Neck dissection was performed in 8 patients. All patients received postoperative radio-iodine. Fifty one cases were papillary carcinoma and 9 cases were follicular carcinoma. Except for one case with local recurrence the remaining cases were disease free on follow up (up to 10-40 months). One patient died with bone metastasis 2 years after operation. Of all thyroid cancers, majority cases are papillary cancer (85%). In contrast to other cancers, thyroid cancer is almost always curable. Most thyroid cancers grow slowly and are associated with a very favorable prognosis. Early diagnosis and treatment of the same is strongly advisable.     

Pattern of malignancy in clinically solitary thyroid nodule

Solitary thyroid nodule (STN) is a common thyroid disorder. Clinically recognized thyroid carcinoma constitutes less than 1% of human malignant tumours. The risk of malignancy in solitary thyroid nodule is greater than other thyroid swelling. The risk of malignancy in generalized thyroid swelling is about 3% and in solitary thyroid nodule it is about 15%. This study was carried out in Surgery and ENT Department, Mymensingh Medical college Hospital from November 2008 to October 2009 to see pattern of malignancy in clinically solitary thyroid nodule. Total 108 patients of STN was included in this study, majority of the patients were within 20-39 years age group with female predominance. In addition to thyroid swelling some patients presented with other symptoms like cervical lymphadenopathy in 6(5.56%), dysphagia 2(1.85%), hoarseness of voice 2(1.85%) and metastatic lesion in bone 1(0.92%) cases. Among 108 cases of solitary thyroid nodule only 19 cases were malignant. Patients with malignant lesion presented with shorter duration of symptoms. Out of 19 malignant cases 6(31.58%) cases presented with features of metastasis. Malignancy was more predominant in male (25.00%) than the female (14.47%) in STN. Out of 19 malignant cases, 12(63.16%) were papillary carcinoma, 5(26.31%) were follicular carcinoma and 2(10.53%) cases were medullary carcinoma. Study showed significant difference (p<0.01) between papillary & follicular carcinoma and significant difference (p<0.001) between papillary & medullary carcinoma. Papillary carcinoma was most common among all thyroid malignancies in patients with solitary thyroid nodule.     

甲状腺乳头状癌滤泡亚型声像图及临床病理特征分析

目的:分析甲状腺乳头状癌滤泡亚型临床病理特征、声像图特征。方法:回顾性分析74例甲状腺乳头状癌滤泡亚型患者(排除小于1 cm的微小癌)的临床病理和超声声像图资料。以同期甲状腺乳头状癌经典型295例、甲状腺滤泡状癌患者21例作为对照纳入本研究。结果:甲状腺乳头状癌滤泡亚型共74例,根据超声声像图不同滤泡亚型分为类经典型亚组55例(74.3%),类腺瘤样亚组19例(25.7%)。甲状腺乳头状癌滤泡亚型的淋巴结转移率较甲状腺滤泡状癌常见,但较甲状腺乳头状癌经典型少见(P<0.05)。甲状腺乳头状癌经典型、甲状腺乳头状癌滤泡亚型和甲状腺滤泡状癌的远处转移率分别为1.4%、2.7%和4.8%。两亚组肿瘤大小、多灶癌的概率、甲状腺外侵犯、淋巴结转移率及TNM分期差异有统计学意义(P<0.05)。结论:拥有超声恶性征象甲状腺乳头状癌滤泡亚型比无恶性征象的更具侵袭性,超声可以帮助预测其临床生物学表现。     

PTTG1IP在甲状腺滤泡上皮细胞起源肿瘤中的表达及意义

目的 探讨PTTG1IP蛋白在甲状腺滤泡上皮细胞起源的不同肿瘤中的表达情况及意义。方法 应用免疫组织化学方法检测PTTG1IP蛋白在25例甲状腺癌旁正常组织、23例滤泡性腺瘤、65例乳头状癌、19例滤泡癌和18例未分化癌中的表达情况。结果 PTTG1IP蛋白表达率在甲状腺癌旁正常组织中为28%,在滤泡性腺瘤组织为30.43%,在乳头状癌组织为61.54%,在滤泡癌组织为31.58%,在未分化癌组织为22.22%。PTTG1IP蛋白在乳头状癌组织的表达率显著高于癌旁正常组织、滤泡性腺瘤组织、滤泡癌组织和未分化癌组织（P<0.05）。PTTG1IP蛋白表达率与甲状腺乳头状癌患者年龄、甲状腺外侵犯和TNM分期明显相关（P<0.05）。结论 在甲状腺滤泡上皮细胞起源的不同肿瘤中,PTTG1IP蛋白过表达可能在乳头状癌的始发和进展中发挥作用,而与滤泡癌和未分化癌的发生发展无关。PTTG1IP蛋白可能是鉴别乳头状癌与甲状腺良性病变及其他恶性滤泡上皮性肿瘤的一个有用指标。PTTG1IP可能为难治的甲状腺乳头状癌提供新的治疗靶点。

Changing patterns of thyroid carcinoma

Background  To assess changing trends in histological types of thyroid cancer in an Irish hospital over the past 30 years. Methods  Biographical data, tumour characteristics, treatment and outcome from 190 patients with thyroid carcinoma from 1970 to 2000 were reviewed retrospectively. Results  Detailed records of 190 patients with thyroid cancer were identified with a mean age at presentation of 50 years. From 1970 to 1979 the distribution of histological types was: papillary carcinoma; 9 patients (4.7%), follicular; 17 patients (8.9%), anaplastic; 9 patients (4.7%), medullary; 1 patient (0.5%) and lymphoma; 1 patient (0.5%). From 1980 to 1989 papillary carcinoma accounted for 32 patients (16.8%), follicular; 14 patients (7.3%), anaplastic; 13 patients (6.8%), medullary; 7 patients (3.7%) and lymphoma; 5 patients (2.6%). From 1990 to 1999 papillary cancer accounted for 48 patients (25.2%), follicular; 14 patients (7.3%), anaplastic; 8 patients (4.2%), medullary; 7 patients (3.7%) and lymphoma; 5 patients (2.6%). Survival rates were significantly better for those aged less than 45 years (P < 0.0001), female sex (P < 0.01) and those with papillary carcinoma (P < 0.01). Conclusions  This study demonstrated a significant increase in the incidence of papillary carcinoma. This may be related to increasing dietary iodine intake and may be significant as papillary carcinoma is associated with a more favourable prognosis.     

Clinicopathological correlation of serum TSH in patients with thyroid nodule

Thyroid nodules and goitre are common. Carcinoma occurs in 5% of thyroid nodules. Early detection and treatment is beneficial to prolonged survival. Higher thyroid stimulating hormone (TSH) level in patient with thyroid nodule is associated with greater risk of differentiated thyroid carcinoma. To assess relationship of TSH with thyroid carcinoma in nodular goitre and usefulness of this marker in predicting likelihood of thyroid malignancy, a study was undertaken among patients with nodular goitre enrolled prospectively during the period 2007 to 2009. Clinically thyroid nodules, confirmed by high resolution USG underwent serum TSH estimation and FNAC of the the nodules. Finally outcome of histopathological examination of resected thyroid specimen were analysed. Overall 33 patients with thyroid nodules were included in this study. Fifteen patients belonged to age group of 31 to 40 years, 13 belonged to 21 to 30 years; 29 were women, 4 were men. Majority of nodules were in right lobe and firm or hard. Fifteen nodules were > 4cm in size. FNAC showed colloid goitre in 24 patients, 7 patients had papillary carcinoma, 2 patients had follicular nodule. Final histopathological report showed 9 papillary carcinoma, 1 medullary carcinoma, 1 follicular carcinoma, 2 follicular adenoma and rest being colloid goitre. Mean TSH value for colloid goitre was 1.8987 mlU/l, for papillary carcinoma it was 2.2400 mlU/l, for follicular carcinoma it was 2.8900 mlU/l, for medullat carcinoma it was 0.8500 mlU/l and for follicular adenoma it was 4.4200 mlU/l. In differentiated thyroid carcinoma TSH value is raised more than in colloid goitre (p = 0.687). Incidence of malignancy in nodular goitre was 30% (11 carcinoma out of 33) in this study. Incidence of malignancy in nodular goitre is rising. Firm to hard nodules, male sex, 3-4 cm sized nodules are mainly susceptible. There is an obvious trend towards cancer risk with higher TSH value. TSH may, therefore, be used as a supportive screening test to predict malignancy in patients with thyroid nodule.

目的探讨分化型甲状腺癌的诊断和治疗方法。方法回顾性分析113例分化型甲状腺癌的临床资料及随访结果。结果全组均行手术治疗辅以内分泌治疗。本组病例中,乳头状癌74例（65.5%）,滤泡状癌39例（34.5%）,淋巴结转移21例（18.6%）。手术方式包括单侧病变行患侧腺叶＋峡部切除28例,患侧腺叶、峡部及对侧大部切除74例,甲状腺全切除术＋双侧颈淋巴结清扫11例。全组无手术及住院期间死亡。结论手术切除是治疗分化型甲状腺癌的主要手段,采取适当的手术方式,辅助术后内分泌治疗,可提高生存率。     

6: Thyroid nodules and thyroid cancer

Thyroid nodules are common clinically (prevalence, about 5%) and even more common on ultrasound examination (about 25%). About 5% of thyroid nodules are malignant. Most thyroid cancers are well-differentiated papillary or follicular tumours with an excellent prognosis (10-year survival, 80%-95%). The incidence of papillary thyroid cancer appears to be increasing on the east coast of Australia. Fine-needle aspiration biopsy of the thyroid is the most cost-effective diagnostic tool. Recommended initial management of all follicular carcinomas and of papillary carcinomas > 1.0 cm is total thyroidectomy followed by radioiodine ablation. Most patients should be managed postoperatively with doses of thyroid hormone sufficient to suppress plasma levels of thyroid-stimulating hormone. Recurrences can occur many years after initial therapy, and follow-up should be lifelong. Thyroid nodules are very common, but have a relatively low risk of malignancy     

甲状腺癌中ret/ptc癌基因表达的研究

目的探讨ret原癌基因活化形式ret/ptc癌基因在甲状腺癌发病机制中的作用和判断其生物学行为。方法应用RTnPCR方法检测了37例甲状腺癌ret/ptc癌基因的表达,包括乳头状癌为26例,滤泡癌8例,髓样癌2例,未分化癌1例。结果26例甲状腺乳状癌中有11例表达为阳性,阳性率为42.3%,8例滤泡癌、2例髓样癌和1例未分化癌均表达为阴性。组织学观察显示,ret/ptc阳性组病例多伴有淋巴细胞浸润(63.6%),显著高于阴性组病例(20.0%,P<0.05),临床病理资料显示,患者发病年龄平均为28.9岁,显著低于阴性组病例的45.9岁(P<0.05),而与患者性别,肿瘤大小,淋巴结转移无显著相关性,随访结果表明在复发病例中无ret/ptc阳性表达病例。结论我们认为ret原癌基因的活化与甲状腺乳头状癌的发生有关,具有ret/ptc癌基因阳性表达的患者一般发病年龄较小,肿瘤恶性程度不高,患者预后相对较好,可作为临床上诊断及判断其生物学行为的参考指标。

Carcinoma of thyroid--clinical presentation and outcome.

The clinical, biochemical and pathological features of 31 patients with thyroid carcinoma managed at Hospital Universiti Sains Málaysia, Kubang Kerian from 1985 to 1989 were analyzed. There were 25 females and 6 males. The types of carcinoma were: papillary-17 cases; follicular-10 cases; medullary-2 cases and anaplastic-2 cases. For papillary carcinoma the mean age of the patients was 52.9 years. For follicular carcinoma the mean age was 48.3 years, for medullary carcinoma, 48.5 years and for anaplastic, 74.5 years. All patients had pre-existing goitre except for 2 and most presented with advanced disease. The mean duration of symptoms for papillary carcinoma was 3.7 years, follicular carcinoma 1.6 years, medullary carcinoma 13.5 years and anaplastic carcinoma 6 months. 12 patients presented with goitre of increasing size; 9 had compression symptoms; 4 presented with cervical lymph node enlargement and 6 presented with bony pains of whom 2 had paraplegia. None of the patients were ever thyrotoxic or hypothyroid. Treatment in general was unsatisfactory because of patients' non-acceptance of surgery and/or radioactive iodine.

CARCINOGENIC EFFECTS OF 131I, 132I AND 123I ON RAT THYROIDS A COMPARATIVE PATHOLOGICAL STUDY

850 male Wistar rats were given intraperitoneal injections of 131I, 1321 and 125I of different radioacti vity for two years. Thyroid dose distribution per µCi of 131I, 132I and 125I was 313.0, 21.1 and 98.5 rads respectively. When the absorbed dosage was over 39 X 10z rads in the 131I group, benign tumors and thyroid gland degeneration occurred. Malignant thyroid gland tumor incidence was 45.8To when the absorbed dose was 7.8 X l02 rads. Optimal carcino- genic doses of 132I and 125I were (6.1-8.4) x l02 rads and (18-94)X102 rads. When i32I is below 2.6 X 10L' rads and rijI below 18.8 x l02 rads, they probably can not induce cancer. 131I mainly induced papillary and mixed type ca,cinoma. 132I chiefly caused follicular and undifferentiated carcinoma; and 125I produced follicular and medullary carcinoma. The toxicity of the three iodine nuclides were 132J>131I>125I. 125I was the least toxic. Knowledge of this is important to radiation protection and clinical practice.
