男性,间断咳嗽、咳痰半年,发热、咯血10天,请诊断!

【所属科室】

呼吸科

【基本资料】

患者,男,46岁

【主诉】

间断咳嗽、咳痰半年,发热、咯血10天。

【现病史】

患者半年前无明显诱因出现咳嗽、咳痰,为白痰,量少,易咳出,伴有气喘,早晚为著。曾至当地医院就诊,服用抗感染药物后可缓解。近半年来上述症状间断出现,表现同前。10余天前患者出现发热,伴寒战,未测体温,咯血2次,每次约5ml,为鲜红色血块。患者自发病以来体力较前下降,近1月体重下降8斤。

【讨论问题】诊断

【讨论】

评论: 右肺下叶肿块影,可见支气管阻塞,考虑中央型肺癌。

【结果】

病理诊断:(气管镜活检,右肺下叶支气管开口)形态学结合免疫组化染色考虑小细胞癌。

【病例小结】

中央型肺癌发生在主支气管、肺叶支气管和肺段支气管。生长类型可分成管外型、管壁型、管内型,其中以管外型为主,以腺癌、鳞癌等为主要病理类型。肿瘤的病理形态包括支气管管壁增厚、管腔内肿物和支气管周围肿块。肿瘤的生长使支气管狭窄或阻塞,可引起阻塞性肺气肿、阻塞性肺炎及阻塞性肺不张,即所谓三阻征象。

X线特征如下:

1 早期X线检查不存在异常表现。
2 伴随患者病情进展,肺门部位可见突向肺野、边缘清晰的肿块影。3 肿瘤组织若阻塞气管可产生典型“三阻征”影像学表现,即阻塞性肺气肿、阻塞性肺炎、阻塞性肺不张,其中以阻塞性肺不张最为常见。阻塞性肺炎——肿瘤阻塞气道时,相应肺段、肺叶区域有模糊索条状片状或索条状影,密度均匀。阻塞性肺气肿——若肺叶体积明显增大,肺纹理较稀疏,透明度较高,横膈、纵膈可受压而移位。肺不张——若气管彻底阻塞,可产生片状肺不张阴影。
4 伴发肺门淋巴结肿大,其下缘有倒“S”状影,即中央型肺癌,是右上叶中央型肺癌典型征象。

CT特征如下:

1 早期CT检查可见其管壁有轻度增厚情况,且管腔中有小结节、管腔阻塞或狭窄;中期、晚期的中央型肺癌患者直接征象为支气管阻塞、狭窄、肺门肿块,以支气管狭窄最为明显,表现为管腔内缘光滑或者不规则,管壁增厚;其中,支气管阻塞的主要表现为管腔变细后阻塞,管腔骤然截断;肺门肿块的主要CT表现为肺门区域外缘光滑,或者出现分叶状软组织肿块影:中央型肺癌间接征象是肿瘤未完全梗阻支气管时所致阻塞性肺气肿,肿瘤彻底阻塞支气管时,其相应部位有阻塞性肺不张、阻塞性肺炎等表现,CT表现为斑片状的模糊影,或者肺叶、肺段实变影;增强扫描后,在明显强化不张肺叶的衬托下,其狭窄支气管会显示的更清楚。

院士领衔扭转食管癌防治尴尬局面

我国是世界上食管癌发病率最高的国家之一。然而,上世纪90年代,我国食管癌患者的5年生存率仅为30.4%,远低于国际平均水平;到本世纪初,我国尚未建立高效、敏感的早期筛查技术,早诊早治目标人群也未确定;由于缺乏本土的规范化治疗指南,我国食管癌治疗策略只能照搬美国,治疗水平难以提高。 如今,食管癌防治的尴尬局面正在扭转。由中国科学院院士、中国医学科学院肿瘤医院院长赫捷领衔的研究团队,历时

患者男性,66岁,有50年的吸烟史和严重的慢性阻塞性肺疾病(COPD),计算机断层扫描(CT)复查结果显示右上叶新发(RUL)肺结节和左下叶(LLL)慢性实变。患者肺功能检查(PFTS)显示气流阻塞,FEV1为2.58 L(81%预测)。6个月前的胸片上LLL实变明显,当地的肺科医生通过常规支气管镜活检检查该病灶,未发现恶性肿瘤的证据。

BMC Cancer:前列腺癌和小细胞癌谱系关系研究

前列腺癌具有不同的形态,而这些不同的形态可以影响患者的治疗结果。这个情况促使了人们思考分化的、可以治疗的前列腺癌与分化不良、不太可能治疗的癌症(包括小细胞癌)之间的关系以及前列腺癌分化的潜在分子机制。最近,有研究人员利用非恶性肿瘤/小细胞癌PDX LuCaP细胞系进行了干细胞转录因子(scTF)LIN28A、NANOG、POU5F1和SOX2的表达分析。研究发现,scTF在小细胞癌LuCaP 93
