  • A-49-year-old male patient with no specific medical history was admitted to the clinic because of persistent epigastric pain radiating to back for 4 months. He had multiple parenchymal tumors in body and tail of pancreas, para-spinal muscle, and mediastinum on abdomen CT image. Cytologic examination of the pancreas which was done by endoscopic ultrasound guided fine needle aspiration (EUS-FNA) showed adenocarcinoma, whereas histological examination of the para-spinal mass showed undifferentiated sarcoma. Histologic examination of the pancreatic mass was made through endoscopic ultrasound guided fine needle biopsy (EUS-FNB) for accurate diagnosis, and the histologic examination of both the pancreas and posterior mediastinal mass showed the same undifferentiated sarcoma. Therefore, we reviewed the cytopathic tissue obtained from the pancreas for the first time, and it was confirmed to be similar to histologic findings in the mediastinal mass.

  • 위암은 최근 50년간 5년 생존율에 있어서 미약하게만 상승되었다. 이에 따라 위암에 대한 분자생물학적 치료에 대한 여러 연구가 진행되고 있다. 이에 진행성, 전이성 위암에서의 분자생물학적 치료에 대해 살펴보고자 한다. 위암의 분자생물학적 치료의 타켓으로는 EGFR (Epidermal growth factor receptor), HER(Human epidermal growth factor receptor), VEGF (Vascular endothelial growth factor receptor)를 들 수 있다. 대표적으로 분자생물학적 치료 중 trastuzumab은 HER2과발현 환자에게 유용하게 사용될 수 있어, 기존 항암화학요법에 복합투여해 볼 수 있다. Trastuzumab와 그 밖의 여러 분자생물학적 제재에 대해 본 연구에서 살펴보고자 한다.

  • 배경: 기관세지페포암종은 흔치않은 폐암으로 $2{\~}14\%$의 유병률을 보인다. WHO의 분류에 따르면 일종의 선암으로 분류되며 최근의 정의에 의하면 흉강내 일차 원발성 선암병변이 없어야 하며, 중심기관지내의 원발병변이 없고, 말초기관에 국한되어야 하며 폐간질의 침범이 없고 암종의 실장이 폐포격막을 따라서 성장해야 한다. 또한 동일병기의 다른 비소세포폐암보다 술 후 생존율이 좋은 것으로 보고된다. 이에 기관세지폐포암의 장기결과에 대한 분석을 하였다. 대상 및 방법: 서울아산병원 흉부외과학교실에서 1990년 1월부터 2002년 12월까지 술 후 기관세지폐포암으로 병리 진단을 받은 31명의 환자를 대상으로 환자의 나이, 성별, 발생부위, 조직학적 병기, 술 후 부작용, 술 후 재발여부, 술 후 항암화학요법, 방사선요법 여부와 술 후 생존여부를 의무기록을 토대로 조사하였다. 결과: 환자의 평균연령은 61.09$\pm$10.63세($31{\~}79$세)이고 남녀의 성비는 12 : 19였다. 발병부위는 우상엽 7예, 우중엽 1예, 우하엽 4예, 좌상엽 8예, 좌하엽 11예였다. 수술은 엽절제술 28예, 전폐절제술 2예였고, 술 후 병리학적병기는 TIN0M0 (stage Ia) 12예($38.70\%$), T2N0M0 (stage Ib) 15예($48.38\%$), T1N1M0 (stageIIa) 1예($3.22\%$), T1N1M0 (stageIIb) 1예($3.22\%$), T2N2M0 (stage IIIa) 1예 ($3.22\%$), T1N0M1 (stage IV) 1예($3.22\%$)였다. 술 후 경과 추적 중에 사망은 4예($12.90\%$)였다. 한 명(T1N0M0, stage Ib)은 술 후 퇴원하였다가 2개월 후에 재발 없이 전신상태 악화에 의한 사망이었고, 한 명(T2N2M0, stage IIIa)은 술 후 29개월째에 우측 늑골 전이로 항암화학요법 중에 사망하였다. 한 명(T1N1M0, stage IIa)은 술후 항암화학요법 중 34개월에 뇌전이가 있었으나 치료거부 후 퇴원하였다가 사망하였다. 한 명(T1N0M0, stage Ib)은 술 후 방사선요법 중에 21개월 째에 양측폐에 다발성 결절을 보이는 전이로 치료 중 사망하였다. 술 후 평균 추적기간은 50.87$\pm$24.77개월이었다. 전체 생존율을 분석해보면 3년에 $97.1\%$, 5년에 $83.7\%$였다. 병기1기 환자의 경우 2년에 $96.3\%$, 5년에 $96.3\%$로 나왔다. 전체 환자의 재발 없는 생존율을 분석해보면 1년에 $100\%$, 2년에 $90\%$, 5년에 $76\%$이고 병기 1기의 경우 2년에 $96.4\%$, 5년에 $90.6\%$였다. 술 후 항암화학요법을 시행한 환자는 7명으로 $22.58\%$이고, 술 후 항암방사선요법을 시행한 환자는 1명으로 $3.22\%$, 2가지 모두 시행한 환자는 2명으로 $6.45\%$였다. 재발부위는 폐전이 3예, 골전이가 1예, 뇌전이가 1예였다. 결론: 기관세지폐포암은 동일병기의 다른 비소세포암보다 수술 절제 후에 비교적 재발률이 적고 병기가 초기인 경우 생존율이 우수함을 알 수 있었다.

  • Background: Diffusion-weighted imaging (DWI) makes it possible to detect malignant tumors based on the diffusion of water molecules. However, it is uncertain whether DWI has advantages over FDG-PET for distinguishing malignant from benign pulmonary nodules and masses. Materials and Methods: One hundred-forty-three lung cancers, 17 metastatic lung tumors, and 29 benign pulmonary nodules and masses were assessed in this study. DWI and FDG-PET were performed. Results: The apparent diffusion coefficient (ADC) value ($1.27{\pm}0.35{\times}10^{-3}mm^2/sec$) of malignant pulmonary nodules and masses was significantly lower than that ($1.66{\pm}0.58{\times}10^{-3}mm^2/sec$) of benign pulmonary nodules and masses. The maximum standardized uptake value (SUVmax: $7.47{\pm}6.10$) of malignant pulmonary nodules and masses were also significantly higher than that ($3.89{\pm}4.04$) of benign nodules and masses. By using optimal cutoff values for ADC ($1.44{\times}10^{-3}mm^2/sec$) and for SUVmax (3.43), which were determined with receiver operating characteristics curves (ROC curves), the sensitivity (80.0%) of DWI was significantly higher than that (70.0%) of FDG-PET. The specificity (65.5%) of DWI was equal to that (65.5%) of FDG-PET. The accuracy (77.8%) of DWI was not significantly higher than that (69.3%) of FDG-PET for pulmonary nodules and masses. As the percentage of bronchioloalveolar carcinoma (BAC) component in adenocarcinoma increased, the sensitivity of FDG-PET decreased. DWI could not help in the diagnosis of mucinous adenocarcinomas as malignant, and FDG-PET could help in the correct diagnosis of 5 out of 6 mucinous adenocarcinomas as malignant. Conclusions: DWI has higher potential than PET in assessing pulmonary nodules and masses. Both diagnostic approaches have their specific strengths and weaknesses which are determined by the underlying pathology of pulmonary nodules and masses.

  • Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland tumor which compromises about 6$\sim$8% of all tumors followed by the adenoid cystic carcinoma (ACC) and adenocarcinoma. Most deaths from salivary carcinomas are caused by recurrent or metastatic lesions that are resistant to conventional therapy. Therefore, knowledge of cellular properties and tumor-host interactions that influence the vascular metastasis is important for the design of more effective therapy of salivary carcinomas. Neoangiogenesis is essential for tumor growth, which is postulated to be fundamentally dependent on the induction of stromal neovascularization. However, how neovascularization takes place in live tissue has not been fully established, especially in recruitment and differentiation of endothelial cells in the salivary gland tumors. Vascular endothelial growth factor (VEGF) is a heparin-binding, dimeric polypeptide growth factor known to exert its mitogenic activity specifically on endothelial cells. VEGF has been shown th be directly involved in angiogenesis, which in essential for the pathogenesis of many solid tumors. von Willebrand factor (vWF) is a large multimeric protein synthesized by megakaryocytes and endothelial cells that enable platelets to adhere to exposed subendothelium and, as well, to respond to changes in the blood flow. Recent studies suggest that increased levels of vWF correlate with progression of disease, metastasis, or survival time and thus may have a prognostic significance. vWF is explained as an acute phase proteins which is increased in cancer or as a result of increased endothelial cell synthesis associated with tumor-induced angiogenesis. Due to adhesive properties of vWF, its increased concentrations may also contribute metastasis of tumor. In this study, we determined the mRNA expression of VEGF and vWF in salivary ACC, MEC and pleomorphic adenoma by in situ hybridization. As a result, stronger expression of VEGF and vWF was seen in salivary ACC and MEC which has more invasive nature than the salivary benign tumor.

  • During the period of 4 years from August 1975 to August 1979 one hundred and forty seven cases of lung cancer were seen at Paik Foundation Hospital in Seoul, Korea. Among these 147 cases, 104 patients had primary carcinoma of the lung and the remainder was metastatic carcinoma to the lung. Among these 104 primary carcinoma patients, 73 cases were proven histologically as primary carcinoma of the lung. There were three cases of alveolar cell carcinoma [Table 1 ]. This clinical observation is based on those 73 cases including three case reports of the alveolar cell carcinoma. 1. Peak incidence was observed in the 5th decade of life. Male to female ratio was 2 to 1 [Fig. 1]. 2. Pathological classifications were as follows: epidermoid carcinoma, 24 cases [32.9%]; undifferentiated carcinoma, 20 cases [27.4%]; adenocarcinoma, 15 cases [20.5%]; bronchioloalveolar carcinoma [5.5%] and positive cytology, 10 cases [13.7%] [Fig. 2]. 3. Evidence of inoperability was observed in 55 patients [75% of the 73 cases] [Table 3]. 4. Among those 73 cases, operability was evaluated in 18 patients or 25%. One patient refused operation and 17 patients [23.6%] were explored. In 11 [15%] out of 17 patients, thoracotomies were performed. Six cases were pneumonectomies and 5 cases were lobectomies or bilobectomies [Fig. 3]. 5. First case of alveolar cell carcinoma was a 46 year-old housewife complaining of cough and hemoptysis for one year. The plain chest X-ray and bronchogram showed characteristic pictures as Figures 4 and 5. A pneumonectomy was carried out. Histologically, a beautiful alveolar carcinoma consisted of the characteristic tall columnar epithelial cells, which were lining the alveolar spaces as seen in Figures 6, 7, 8, and 20. 6. In the second case of 41 year old male, predominant clinical feature was single, well defined mass in the right lower lobe [Fig. 10 and 11] on chest X-ray. Bilobectomized specimen showed fragile, soft and hard tissue containing mucoid secretions and focal yellowish necrosis with pigmentation on cut surface [Fig. 12]. Slides showed tumor cells lined up along the alveolar septa with papillary projections [Fig. 13 and 14]. 7. Third case of alveolar cell carcinoma was a 50-year-old housewife with hemoptysis. An outstanding clinical picture was a round to lobulated mass in the right upper lobe [Fig. 16]. She is living now, 2 years and 1 month post-operatively, but has arrived at terminal stage with military nodular disseminations to the contralateral lung [Fig. 19].

  • Background: Cervical metastasis of unknown origin is defined as histologic evidence of malignancy in the cervical lymph nodes with no apparent primary site of origin for the metastatic tumor. Patients and Methods: A retrospective review of 20 cervical metastasis of unknown origin diagnosed and managed between january 1989 and December 1999 at the Korea University was undertaken to determine outcome. Patient age ranged 46 to 78 years (mean 60). There were 17 men and 3 women. The aim of this study is to ananlyze the diagnostic approach and the result of treatment of the cervical metastasis of unknown origin. Result: Histopathologically, squamous cell carcinoma (15 case, 75%) were the most common, followed by adenocarcinoma (4 case, 20%), undifferentiated carcinoma (1 case, 5%) According to the criteria of the AJCC on staging, N1 was 2 cases, N2a 2 cases, N2b 5 cases, N2c 1 cases, N3 10 cases. Overall survival rate for all patients at 2 years was 45% and 5 years 25%, and in the combination therapy(surgery and radiotherapy group (12 cases)) it was 67% and 34% respectively, high compared with other treatment modality such as surgery or radiotherapy alone. In extracapsular spread positive group, 5 year survival rate was 12%, but was 33% in the extracapsular spread negative group. Conclusion: With no stastatical significance, extracapsular spread group was poor outcome in our study. Combination of radiotherapy and surgery was more effective treatment result than surgery alone or radiotherapy alone in our study. But, overall prognosis of cervical metastasis of unknown origin was very poor despite aggressive treatment (5 year survival rate: 25%).

  • Although correlations between platelets and lung cancer has been recognized, effects on non-small cell lung cancer (NSCLC) metastasis remain to be determined in detail. In the present study, wound healing assays revealed a role of platelets in NSCLC cell migration. Thus the mean migration rate of lung adenocarcinoma A549 cells was significantly elevated after co-culture with platelets ($81.7{\pm}0.45%$ vs $41.0{\pm}3.50%$, P<0.01). Expression of GAPDH was examined by reverse transcription-polymerase chain reaction to study the effect of platelets on NSCLC cell proliferation. The result showed that the proliferation of A549 and SPC-A1 cells was not affected. Mouse models were established by transfusing A549 cells and SPC-A1 cells into mice lateral tail veins. We found tumor metastasis nodules in lungs to be increased significantly after co-transfusion with platelets (in A549, $4.33{\pm}0.33$ vs $0.33{\pm}0.33$, P=0.01; in SPC-A1, $2.67{\pm}0.33$ vs $0.00{\pm}0.00$, P=0.01). In addition, consecutive inoperable patients with newly diagnosed NSCLC (TNM stage III or IV) between January 2009 and December 2011 were retrospectively reviewed. Using the Kaplan-Meier method, NSCLC patients with a high platelet counts demonstrated a significantly shorter progression free survival compared with those with a low platelet count (> $200{\times}10^9/L$, 3 months versus ${\leq}200{\times}10^9/L$, 5 months, P=0.001). An elevated platelet count was also identified as an independent prognostic factor by Cox regression analysis for prgression free survival (adjusted hazard ratio: 1.69; 95% CI: 1.16, 2.46; P=0.006). This study suggested that platelets might contribute to the hematogenous metastatic process by promoting cancer cell migration, which eventually affects the prognosis of NSCLC.
