  • Diagnosis and Treatment of 178 Cases of Thyroid Cancer

    【摘要】目的 探讨甲状腺癌的诊断及治疗方法。方法 回顾性分析我院1999~2003年期间收治的178例行手术治疗的甲状腺癌患者的临床资料。结果 本组患者术前B超检查均发现甲状腺内实性或囊实性结节,其中结节内伴微钙化灶者50例(28.1%),B超检查对于颈部淋巴结转移的阳性预告值为78.1%。行术中冰冻切片检查162例,诊断甲状腺癌144例,阳性率为88.9%。术后病理检查证实有淋巴结转移者为34.3%(61/178),甲状腺癌局部或患侧叶切除术后行二次以上手术者30例,残癌率为43.3%(13/30)。结论 声音嘶哑及B超检查提示甲状腺结节内微钙化灶对甲状腺癌的术前诊断有重要提示意义,亦可作为是否行颈淋巴结清扫的指征之一。术中冰冻切片检查是确诊甲状腺癌的最佳方法。患叶+峡部+对侧大部切除是甲状腺癌的主要手术方式。

  • 罕见Riedel甲状腺炎的诊断及处理

      Riedel甲状腺炎又名慢性纤维性甲状腺炎或侵袭性纤维增生性甲状腺炎,是一种罕见的甲状腺侵袭性慢性炎症。北京协和医院1977~2005年28年间共收治8例,均为女性,年龄39~55岁,平均49岁; 病程2周~6年,平均16个月。临床表现为颈部结节者5例, 颈部不适者2例,憋气者1例。术前B超检查发现甲状腺内多发结节者5例,单个结节者2例,弥漫性肿大者1例。31I吸收率检查正常4例,降低3例,升高1例; 气管相检查发现气管受压移位者4例,狭窄者2例。全部患者均行手术治疗,术中发现甲状腺质硬结节,多发者5例,单发者2例,均位于峡部,弥漫性肿大者1例; 结节固定,与颈前肌及气管粘连紧密。行甲状腺腺叶切除4例,峡部切除2例,活检2例。冰冻切片检查结果均为甲状腺炎症,其中明确诊断为Riedel甲状腺炎者2例,术后病理检查均证实为Riedel甲状腺炎。术后除1例患者出现甲状腺及甲状旁腺功能低下,对症治疗后症状缓解以外,其余患者均痊愈。  讨论 本病病因不明,目前多数学者认为应将本病看成是一个独立的疾病,一般认为本病是原发的,其有可能与特发性纤维硬化性疾病及自身免疫有关。本病发病率很低,约在0.1%左右。本组病例占我院同期甲状腺手术患者的0.065%。本病好发于中老年女性,男女比例为1∶4。通常表现为甲状腺无痛性肿块,病程可为数月或数年,甲状腺常呈不对称肿大,质地硬韧甚至成所谓“木样”或“石样”。甲状腺多有明显结节感,可产生压迫症状。Riedel病的甲状腺萎缩和纤维化与桥本或其他慢性甲状腺炎的终末阶段在病理表现上有本质不同: ①在本病纤维化过程不仅只限于被膜内,还进入周围组织形成广泛粘连,这是本病所特有的; ②本病的甲状腺病变不均匀,很少有整个甲状腺被累及; ③病变部位甲状腺结构完全被破坏,镜下所能观察到的仅是纤维瘢痕组织及其粘连的横纹肌。本病术前诊断有一定困难。临床上很难与未分化癌和桥本甲状腺炎区分。诊断的确立依靠病理检查,对怀疑本病者应行病理活检。Riedel甲状腺炎是一种自限性疾病,如无压迫症状应进行保守治疗; 有压迫者仅行峡部楔形切除以解除气管压迫,没必要切除所有病变组织,否则可能导致甲状腺功能低下。本病为良性疾病,有局限化趋势,手术目的主要为了除外恶性病变及解除气管压迫,术后病变不再发展,基本上不需2次手术。

  • Clinical study on metastatic lung cancer to thyroid gland

    Objective To analyze and summarize clinical characteristics, diagnostic method, choice of treatment, and prognosis of metastatic lung cancer to thyroid gland. Method The clinical materials of the 15 patients presenting with secondary thyroid cancer were analyzed retrospectively. Results There were 10 females and 5 males in the 15 patients, with the female to male ratio of 2 : 1. The age ranged from 36 to 79 years old with an average 59 years old. The diagnoses of 12 cases were made by the surgery or the fine needle aspiration biopsy (FNAB), 3 cases by the clinic. The interval from the diagnosis of the primary tumor to the thyroid metastasis varied from 0 month to 21 months with an average 4 months. Three patients received the thyroidectomy, 5 patients received the chemotherapy or chemoradiotherapy, and 7 patients gave up the treatment. The average survival time was 10 months. Conclusions Metastatic lung cancer to thyroid gland is rare, and FNAB is a useful tool for diagnosis. Thyroidectomy may not be recommended because of poor prognosis.

  • Reoperation of Solid Pseudopapillary Tumor of Pancreas: Clinical Analysis of 4 Cases

    目的 总结胰腺实性假乳头状瘤再次手术病例的诊断和治疗经验。方法 回顾性分析2002年12月至2011年12月期间笔者所在医院收治的4例胰腺实性假乳头状瘤再次手术患者的临床资料。结果 4例患者均行手术治疗,术后恢复良好,随访时间3个月~8年,平均47个月。至2012年3月,3例患者分别无瘤生存3个月、3个月以及8年;1例患者于术后8年死于营养吸收障碍,死亡时无肿瘤复发。结论 胰腺实性假乳头状瘤具有低度恶性倾向,以局部复发为主,远处转移少见。手术是复发、转移病例的最佳选择,具有较好疗效。

  • Establishment of Adriamycin-Resistant Human Pancreatic Cancer SW1990/ADM Cell Line and to Investigate Its Resistance Mechanism

    【Abstract】ObjectiveTo establish adriamycin (ADM) resistant pancreatic cancer cell line SW1990/ADM and to investigate its drug resistance mechanism.MethodsADM-resistant pancreatic cancer cell line SW1990/ADM was obtained by culture of pancreatic cancer cell line SW1990 in vitro with intermittently increasing the concentration of ADM in the culture medium for ten months. After two months of drug free culture, its biological characteristics, drug sensitivity as well as the expression and function of multidrug resistant gene 1 (mdr1) were detected, respectively. ResultsCompared with the parental cell line, SW1990/ADM showed great changes in biological characteristics and developed a cross resistance to various chemotherapy drugs. The drug resistance indexes of cell line SW1990/ADM to ADM, mitomycin, fluorouracil and gemcitabine were 49.60, 7.25, 3.80 and 1.25, respectively. The level of mdr1 mRNA expression in cell line SW1990/ADM was much higher than that of the parental cell line(P<0.01). ConclusionWe have established adriamycin resistant pancreatic cancer cell line SW1990/ADM with multidrug resistance phenotype, its multidrug resistance is positively relevant to the expression of mdr1.
