正原发性主动脉食管瘘是由于动脉壁糜烂、溃疡,穿破邻近食管所致,临床上罕见,Salmon 1843年正式报道首例,至1998全世界报道的病例不超过250例~[1,2],超过80%为主动脉肠瘘,主动脉食管瘘极为罕见~[3]。因发病凶险,诊断困难,极易误诊,死亡率高。我院2017年5月确诊1例,通过复习该病例诊治经过,并结合文献报道的15例,探讨该病的临床     

肺癌术后骨骼肌转移1例报道并文献回顾

<正>肺癌是世界范围内肿瘤死亡的首要原因。非小细胞肺癌占肺癌的80%。大约50%的患者在诊断时已发生转移。肺癌常见转移部位为脑(10%)、骨(7%)、肝(5%)及肾上腺(3%)[1,2]。虽然骨骼肌占人体总体重的接近50%,但肿瘤发生骨骼肌转移十分罕见。本文报道我院收治的1例肺癌术后骨骼肌转移病例,同时复习相关文献,了解肺癌骨骼肌转移的临床特点及诊治现状。     

肺炎型肺癌1例并文献复习

肺癌骨骼肌转移1例报道及文献复习

<正>原发性支气管肺癌(简称"肺癌")是最常见的恶性肿瘤之一,近几年因环境污染的日益严重,发病率逐年上升。肺癌是世界范围内肿瘤死亡的首要原因,即使目前在诊断及治疗上已取得了重大的进步,但其各个分期总的5年生存率仍仅有14%,而早期诊断率低是主要因素。肺癌常见转移部位为脑、骨、肝及肾上腺,软组织转移包括骨骼肌转移十分罕见。本文报道我院收治的1例以肌肉疼痛为首发症状的肺腺癌骨骼肌转移病例,同时复习相关文献了解肺癌伴骨骼肌转移的临床特点及诊治现状。     

原发性肺黑色素瘤1例报道并文献复习

目的 分析原发性肺黑色素瘤(PMML)的流行病学及临床、病理特点,提高临床医师对PMML的诊断水平.方法 报道了济宁市第一人民医院呼吸科1例经病理确诊的PMML,并对其病理特点及32例PMML患者的治疗进行回顾分析.结果 患者,男,22岁,主因“反复咯血8个月,加重3d”于2011年3月31日在我院呼吸科住院治疗.肺CT是多发结节灶,后行胸腔镜肺活检病理示黑色素瘤.迄今为止,国外诊断PMML 32例,国内报道22例,主要症状为咯血,咳嗽.影像学为孤立性病灶多见.结论 本例肺内多发结节的PMML患者在国内外都是首例报道.手术是目前最好的方法,晚期可以给予放化疗.

多原发性肺癌1例报告并文献复习

多原发性肺癌是指一侧肺或两侧肺的不同部位发生2个或2个以上原发癌,其组织类型相同或不同,但各肿瘤之间无从属关系[1].多原发性肺癌的发生率报道不一,0.2％～20％不等[2],发病原因认为与宿主的肿瘤易感性、免疫功能异常、罹患第1种肿瘤后生存期延长、首次术后放化疗、内分泌紊乱等潜在因素有关.自1924年Beyreuther描述了第1例双原发性肺癌(double primary lung cancer,DPLC)后,其发病率和诊断便不断有报道[3].近年来发病有增多趋势,检出率不断增加,正确认识和处理该病有着重要的临床意义.我科今年收治1例DPLC(右上肺鳞癌+左下肺小细胞癌)患者,现报告如下,并结合文献进行探讨.     

肺癌骨骼肌转移2例并文献复习

目的探讨肺癌骨骼肌转移的临床、影像学特点、治疗方法和预后。方法收治的2例肺癌骨骼肌转移患者及国内外相关文献进行回顾性分析。结果疼痛是骨骼肌转移最常见的症状。多数转移灶可以触及。骨骼肌转移病灶增强CT检查提示边缘强化中央密度减低的肿块影。CT或超声引导下穿刺活检有助于明确诊断。在原发肿瘤控制的情况下,单发骨骼肌转移患者接受骨骼肌手术或根治放疗生存期更长。结论肺癌骨骼肌转移预示疾病进展,如果肺原发病灶可治愈,对于骨骼肌单发转移,应积极争取外科手术治疗或根治放疗。     

Radical Resection for Second EGFR-mutated Primary Lung Cancer Following Immune Checkpoint Inhibitor Monotherapy for Stage IV Lung Adenocarcinoma

A 78-year-old woman with multiple lung nodules, epithelial growth factor receptor (EGFR) exon 20 insertion mutations, and diagnosed with advanced lung adenocarcinoma (cT4N3M1a, stage IVA), was referred to our hospital. She received immune checkpoint inhibitor (ICI) therapy. The therapy showed remarkable antitumor effects; only a single nodule remained in the right upper lobe. The nodule was diagnosed as adenocarcinoma through a biopsy. We subsequently performed right upper lobectomy for multiple primary lung cancer (MPLC). The surgical specimen contained EGFR exon 19 deletion mutations and not exon 20 insertion mutations.     

Vimentin-positive and Alpha-fetoprotein-elevated Nuclear Protein of the Testis Midline Carcinoma: A Case Report and Review of the Literature

Nuclear protein of the testis (NUT) midline carcinoma (NMC) is a rare malignant tumor expressing NUT with BRD4/3 rearrangements and is sometimes misdiagnosed as germinoma, especially in alpha-fetoprotein (AFP)-elevated cases. A 28-year-old man had a mediastinal tumor with multiple bone metastases and elevated AFP levels. Imaging/laboratory findings led to a pathological diagnosis of extragonadal germinoma. After unsuccessful treatment with etoposide-cisplatin, he was re-diagnosed with sarcoma due to vimentin-positive findings. He was treated with adriamycin-ifosfamide, which resulted in disease-control. A posthumous examination clarified the NUT rearrangement. Even in cases with characteristic findings, such as elevated AFP levels and vimentin positivity, NMC should be considered as a differential diagnosis. We note, however, that adriamycin-ifosfamide has some efficacy in such cases.     

Synchronous Primary Lung Adenocarcinoma and Hepatocellular Carcinoma Successfully Treated with a Combination of Atezolizumab,Bevacizumab, Carboplatin,and Paclitaxel

Chemotherapy for multiple primary malignancies is challenging. We herein report a case of synchronous primary lung adenocarcinoma and hepatocellular carcinoma (HCC). A 72-year-old man was admitted for the evaluation of an abnormal shadow on his lung. Computed tomography revealed a lung nodule in the right upper lobe and multiple liver masses. He was diagnosed with synchronous primary lung adenocarcinoma and HCC. Atezolizumab, bevacizumab, carboplatin, and paclitaxel (ABCP) chemotherapy was efficacious for both tumors. ABCP chemotherapy may be a potential treatment option for synchronous primary lung adenocarcinoma and HCC.

Osimertinib for Lung Squamous Cell Carcinoma: A Case Report and Literature Review

The efficacy of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in lung squamous cell carcinoma is said to be low. Thus far, only four cases of osimertinib in lung squamous cell carcinoma have been published. We experienced a case of EGFR mutant lung squamous cell carcinoma in which fifth-line treatment with osimertinib was effective after T790M EGFR mutation turned positive. Osimertinib was resumed after sixth-line chemotherapy was ineffective, showing efficacy again. Osimertinib may be a promising treatment option for EGFR mutant lung squamous cell carcinoma. This is the first report to show its effect in a case of rechallenge after intervening chemotherapy. It may therefore be important to evaluate EGFR in never-smoker lung squamous cell carcinoma patients.     

Primary Cardiac Lymphoma: Case Report and Brief Review of the Literature

Primary cardiac lymphoma is defined as a non-Hodgkin's lymphoma mainly located in the heart and/or the pericardium. It is rare and affects elderly men. Common manifestations are pericardial effusion and heart failure. Diagnosis is usually late and prognosis is poor. We report a case of a patient with a large primary cardiac lymphoma who presented with chest pain and negative T-waves in electrocardiogram. Transthoracic echocardiogram showed a large mass in the right atrium and right ventricle while transesophageal echocardiogram also revealed the presence of large mobile masses in the right atrium, which were considered to be thrombi. Tissue biopsy showed a high-grade B-cell diffuse lymphocytic lymphoma. The patient was treated with chemotherapy and radiation with complete remission and prolonged survival.     

Muscular Metastasis of Hepatocellular Carcinoma: Case Report and Literature Review

There are few case reports of hepatocellular carcinoma (HCC) metastasis to the skeletal muscle. A 78-year-old man developed a mass in the right shoulder. Washout of contrast medium during contrast-enhanced ultrasonography (CEUS) in both the primary HCC and the metastatic site was detected. Several nodules were scattered throughout the liver on an autopsy. In addition, the moderately differentiated HCC had metastasized to the right teres major muscle. Rare muscular metastasis should be considered if a hepatic tumor is moderately or poorly differentiated HCC. Early washout during CEUS is consistent with a pathological diagnosis of moderately or poorly differentiated HCC.     

Primary Gastric Tuberculosis: A Case Report and Literature Review

Gastric tuberculosis is a rare entity; it usually occurs secondary to another lesion(s), mainly in the lungs. Only a few cases of primary gastric tuberculosis have been reported in the literature. Most commonly, gastric tuberculosis lesion(s) is located in the lesser curvature of the antrum and prepylorus, so the clinical picture is similar to that of peptic ulcer, in addition to the constitutional symptoms seen in tuberculosis in general. We report a case of a young man presented with abdominal pain acute gastric outlet obstruction due to a large mass in the lesser curvature of the antrum and the pylorus. The histological examination revealed caseating granuloma with the presence of acid-fast bacilli. Partial gastrectomy with Bilroth II reconstruction was performed and the patient was put on antituberculosis medications. There was no evidence of the tuberculous lesion anywhere else. Patient's follow-up observation in the clinic was uneventful.     

Leveraging Primary Care in the Fight Against Lung Cancer

In recent years, the decline in youth smoking rates has stopped as the tobacco industry strives to successfully reclaim market areas where it has lost favor. The plateau in lung cancer incidence and stagnation in progress toward smoking abstinence illustrates the necessity for renewed efforts to fight tobacco use. Barriers to fighting tobacco use exist in both the clinical arena and within the general population, but can be overcome. Primary care physicians (PCPs) are uniquely poised to successfully treat nicotine dependence with strategic targeting of these barriers, improved training in smoking cessation techniques, and focused political efforts in tobacco control. Herein, this article describes the landscape of tobacco use in America and provides background, methodology, and resources for PCPs to help achieve the goals of Healthy People 2010 in reducing the illness, disability, and death that occur as a result of tobacco use and exposure to secondhand smoke.
