  • The aim of this study was to evaluate the diagnostic value of interleukin 21(IL-21) and carcinoembryonic antigen (CEA) in tuberculous pleural effusions (TPEs) and malignant pleural effusions (MPEs). Pleural effusion samples from 103 patients were classified on the basis of diagnosis as TPE (n=51) and MPE (n=52). The concentration of IL-21 was determined by ELISA. Lactate dehydrogenase (LDH), adenosine dehydrogenase (ADA) and CEA levels were also determined in all patients. A significant difference was observed in the levels of ADA and CEA (P<0.01), but not in the levels of LDH (P>0.05) between TPE and MPE. The concentration of IL-21 in MPE was significantly higher compared to TPE (P<0.01). With a threshold value of 4.32 pg/ml, IL-21 had a sensitivity of 76.9% (40/52) and a specificity of 80.4% (41/51). Combined detection of IL-21 and CEA had a sensitivity of 69.2% (36/52) and a specificity of 92.2% (47/51). These two markers can contribute to the differential diagnosis of MPEs.

  • 연구배경: 악성 흉수가 있는 환자는 예후가 좋지 않아 이를 감별하는 것은 임상적으로 중요한 일이다. 하지만 흉수 내 세포진 검사가 음성일 경우 진단이 쉽지 않다. 따라서 본 연구는 흉수 탈락 세포에서 추출한 DNA에서 종양억제 유전자로 알려진 retinoic acid receptor b2 (RARB2)와 p16 유전자의 과메틸화 측정이 악성 흉수 진단에 도움이 될 수 있을지를 확인하기 위하여 실시하였다. 방법: 43명의 환자에서 흉수를 천자하여 흉수 내 탈락 세포에서 메틸화 특이 PCR 방법으로 RARB2와 p16 유전자의 과메틸화를 측정하고, 이를 흉막 생검 및 흉수 세포진 검사법과 비교하였다. 결과: 43명의 환자 중 17명은 폐렴, 결핵에 의한 양성 흉수 환자였고, 26명은 흉막 침범 폐암 환자였다. 17명의 양성 흉수에서는 흡연 유무와 상관없이 RARB2와 p16 유전자의 과메틸화가 관찰되지 않았다. 26명의 악성 흉수에서 과메틸화는 각각 14명, 5명에서 관찰되었으며, 두 유전자 중 어느 한 쪽이라도 과메틸화가 생긴 경우는 15명이었다. 흉막 생검, 흉수 내 세포진 검사, RARB2 단독, p16 단독, 두 유전자 동시 측정 과메틸화 검사의 민감도는 각각 73.1%, 53.8%, 53.8%, 19.2%, 57.7%이었고, 음성 예측도는 각각 70.8%, 58.6%, 58.6%, 44.7%, 60.7%로서 두 유전자를 동시에 검사할 때의 민감도와 음성 예측도는 흉막 생검보다는 낮았지만, 흉수 내 세포진 검사보다는 높았다. 또, 소세포암에서 p16를 이용한 민감도가 14.3%로 떨어져서 조직 유형에 따른 차이를 보였다. 결론: 본 연구 결과에서 p16과 RARB2 유전자의 과메틸화의 발견은 악성 흉수를 양성과 감별하는데 높은 특이도를 보였고, 민감도 역시 흉수 내 세포진 검사보다 높은 방법이었다. 폐암의 세포 유형에 따른 분자 생물학적 병리를 이해하고 적절한 유전자를 선정한다면 이런 결과는 더욱 향상될 수 있을 것으로 생각된다.

  • We present a case of an unusual infectious complication of a ruptured mediastinal abscess after endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), which led to malignant pleural effusion in a patient with stage IIIA non-small-cell lung cancer. EBUS-TBNA was performed in a 48-year-old previously healthy male, and a mediastinal abscess developed at 4 days post-procedure. Video-assisted thoracoscopic surgery was performed for debridement and drainage, and the intraoperative findings revealed a large volume pleural effusion that was not detected on the initial radiographic evaluation. Malignant cells were unexpectedly detected in the aspirated pleural fluid, which was possibly due to increased pleural permeability and transport of malignant cells originating in a ruptured subcarinal lymph node from the mediastinum to the pleural space. Hence, the patient was confirmed to have squamous cell lung carcinoma with malignant pleural effusion and his TNM staging was changed from stage IIIA to IV.

  • Desmoid tumor (fibromatosis) is a histologically benign fibrous neoplasm showing locally infiltrating growth. This type of tumor commonly occurs in the abdomen, but intrathoracic desmoid tumor is uncommon. To date, 12 cases of intrathoracic desmoid tumor protruding into the pleural cavity, radiologically mimicking pleural masses, have been reported. Here, we report on a case of intrathoracic desmoid tumor protruding into the pleural cavity, and partially covered by parietal pleura. The main preoperative differential diagnoses included pleural solitary fibrous tumor, inflammatory pseudotumor or malignant mesothelioma. A near-total mass excision was performed. Pathologically, the tumor was composed of a paucicellular arrangement of spindle-shaped cells with fibromyxoid stroma. The resection margin was partially involved with spindle cells present. On histochemical staining, the spindle cells were strongly positive for vimentin and negative for CD34, consistent with a desmoid tumor. The patient was stable without further adjuvant treatment during 6-years of follow-up.
