Purpose: The aim of this study was to investigate the impact of preoperative low body mass index (BMI) on both the short- and long-term outcomes in patients with gastric cancer. Materials and Methods: A total of 510 patients with gastric cancer were divided into the following 3 groups: low BMI group (${\leq}18.5kg/m^2$, n=51), normal BMI group ($18.6-24.9kg/m^2$, n=308), and high BMI group (${\geq}25.0kg/m^2$, n=151). Results: There were significantly more stage III/IV patients in the low BMI group than in the other groups (P=0.001). Severe postoperative complications were more frequent (P=0.010) and the survival was worse (P<0.001) in the low BMI group. The subgroup analysis indicated that survival was worse in the low BMI group of the stage I/II subgroup (P=0.008). The severe postoperative complication rate was higher in the low BMI group of the stage III/IV subgroup (P=0.001), although the recurrence rate and survival did not differ in the stage III/IV subgroup among all the BMI groups. Low BMI was an independent poor prognostic factor in the stage I/II subgroup (disease-free survival: hazard ratio [HR], 13.521; 95% confidence interval [CI], 1.186-154.197; P=0.036 and overall survival: HR, 5.130; 95% CI, 1.644-16.010; P=0.005), whereas low BMI was an independent risk factor for severe postoperative complications in the stage III/IV subgroup (HR, 17.158; 95% CI, 1.383-212.940; P=0.027). Conclusions: Preoperative low BMI in patients with gastric cancer adversely affects survival among those with stage I/II disease and increases the severe postoperative complication rate among those with stage III/IV disease.

The records of 65 patients with a confirmed diagnosis of primary lung cancer who underwent surgical therapy at the Department of Thoracic and Cardiovascular Surgery of the Keimyung University Hospital were analyzed during the period of 8 years and 4 months, from August, 1978 to December, 1986. The peak incidence was observed in the 5th decade of life and the mean age was 52.9 years old. Male versus female ratio was 8.3:1 Cough was the most frequent presenting symptom, 76.9% then chest discomfort, hemoptysis and dyspnea followed in order. 44.6% of the patient had 2 months of prediagnostic symptomatic period, 72.3% had 5 months, and the mean was 5.7 months. As for preoperative diagnosis, 62 of total 65 patients revealed the mass lesion on simple chest x-ray, and 56 of 65 patients on bronchoscopic biopsy, 10 of 37 patients on sputum cytology and 15 of 15 patients on computerized tomography of the chest were positive. Of the 65 patients, 35 [53.9%] had squamous cell carcinoma, 18 [27.7%] adenocarcinoma, 3 [4.6%] large cell carcinoma, and 3 [4.6%] small cell carcinoma all which was oat cell carcinoma. 83.1% of the total patient was resectable, and 34 underwent pneumonectomy and 20 lobectomy. Of these 65 operations, 29 was radical resection, 25 palliative, and 11 exploratory thoracotomy. As for clinical stagings, 23 patients were in Stage, I, another 23 in Stage II and 19 in Stage III, while 16 was in stage, I, 14 in stage ll and 35 in stage III in postoperative staging evaluation. In correlation of postoperative TNM classification and radical resection, those patients who had lung cancer of stage I [14/16] and stage II [9/13] had more radical resection. As postoperative complications, one patient had massive bleeding, two empyema, one empyema with bronchopulmonary fistula, and one cardiac herniation. Operative mortality rate was 1.5% [1 patient]. Mean duration between 1st operation and discovering recurrence in 18 patients was 12.7 months.

With the widespread use of the obstetrical ultrasound, identification of a fetal suprarenal mass becomes more common. Most of these masses prove to be congenital neuroblastomas (CNB) postnatally. However, the diagnosis is often confused with other benign lesions and the post-natal management remains controversial. The medical records of 13 patients that underwent primary surgical excision for an antenatally detected adrenal CNB, between January 1995 and April 2009, were reviewed retrospectively. The clinical, radiological, surgical, and pathological data on the suprarenal mass were collected. Staging evaluation was performed after histological confirmation of the CNB. Most of the CNBs were stage I (N=11), with 1 stage IV and 1 stage IV-S. Four patients (3 stage I and 1 stage IV-S) had N-myc gene amplification. The stage I patients were cured by surgery alone, and stage IV patients underwent 9 cycles of adjuvant chemotherapy and currently have no evidence of disease after 39 months of follow-up. The patient with stage IV-S is currently receiving chemotherapy. There were no post-operative complications. For early diagnosis and treatment, surgical excision should be considered as the primary therapy for an adrenal CNB detected before birth. The surgery can be safely performed during the neonatal period and provides a cure in most cases. Surgical diagnosis and treatment of CNB is recommended in neonatal period.

Purpose: To analyze treatment modalities and prognostic factors in patients with Stage I-II endometrial stromal sarcoma (ESS). Materials and Methods: Twenty four patients (nineteen with low-grade ESS [LGESS] and five with high-grade ESS [HGESS]) were assessed retrospectively in terms of general characteristics, prognostic factors, treatment methods and survival. Results: Twenty patients were at Stage I and three were at Stage II. The stage of one patient could not be determined. With respect to age and comorbidity, no statistically significant difference was found among disease-free survival (DFS) (p=0.990; p=0.995). However, DFS was significantly shorter in Stage II than Stage I patients (p=0.002). It was also significantly shorter in HGESS patients than in LGESS patients (p=0.000). There was no statistically significant differences among the overall survival (OVS) times of patients with respect to age at diagnosis and comorbid disease (p=0.905; p=0.979) but OVS was significantly shorter in patients with HGESS (p=0.00) and Stage II disease (p=0.001). No statistically significant difference was found with respect to OVS between patients who received radiotherapy (RT) and those who did not receive RT (p=0.055). It was not statistically possible to include other treatment modalities in the analysis because of the small sample size. Conclusions: Grade and stage of a tumour were found to be the most important prognostic factors. It was not possible to determine the optimal surgical method and the effect of adjuvant treatment since the number of cases was insufficient.

Background: Upper tract transitional cell carcinomas (UTCC) are relatively uncommon but prognosis is generally worse than TCC of bladder. Methods: Between March 2004 and June 2012, patients with initial non-metastatic UTCC were assessed in the Medical Oncology and Urology Departments of Ataturk Training and Research Hospital. Results: A total of 11 patients with initially non-metastatic UTCC were detected in the 8 year period, all males. Median age of was 62 (range, 38-74). Six lesions were located in the renal pelvis and 5 in the ureter. Nephroureterectomy was performed in 9 patients, and distal ureterectomy and cuff excision of the bladder in the remaining 2. The majority (n= 9) had high grade tumors. Median primary tumor diameter was 3.5 cm (range, 0.7-10). Five patients (45.5%) were stage I, 2 (18.2%) were stage II, and 4 (36.4%) were stage III. While adjuvant chemotherapy was not applied for stage I and II disease (n= 7), 4 to 6 courses were applied for 3 of the stage III patients. Also one stage III case received adjuvant radiotherapy. Up to 100 months follow-up, median overall survival was 13 months (range, 5-100 months). While stage I and II patients are following-up without muscle-invasive progression, 2 of stage III patients demonstrated progression. Conclusion: We need more collaborative studies to determine management of especially pT3-pT4 patients with UTCC.

Objectives: Angiogenesis and lymphangiogenesis are correlated with tumor growth and lymph node metastasis in cases of oral squamous cell carcinoma (OSCC). Endoglin is one of the representative vascular endothelial cell markers. Podoplanin is also a representative marker used in order to detect lymphatic endothelial cells. The aim of this study was to determine the correlation between the expression of endoglin/podoplanin and clinical variables associated with OSCC progression. Materials and Methods: Paraffin embedded tissue specimens from 21 patients diagnosed with OSCC were used in this study. Ten patients were diagnosed with early clinical stage (I or II) and 11 patients with advanced clinical stage (III or IV) OSCC. Five patients had positive lymph node involvement. Primary antibodies for endoglin and podoplanin were used to perform the immunohistochemical detection of the vascular and lymphatic endothelial cells. The expression of endoglin and podoplanin was examined by an image analysis program in the three most highly expressed regions of each specimen. Results: The average endoglin expression was observed to be $1.691{\pm}0.920$ in the advanced stage (III, IV) specimens and $0.797{\pm}0.583$ in the early stage (I, II) specimens (P=0.020). The average expression of podoplanin was $0.286{\pm}0.228$ in the advance stage (III, IV) specimens and $0.374{\pm}0.157$ in the early stage (I, II) specimens (P>0.05). There was no statistically significant difference in the expression of endoglin and podoplanin, regardless of whether or not the lymph node was positive. Conclusion: The expression of endoglin was significantly higher in the advanced stage specimens than that in the early stage specimens. Therefore, we concluded that endoglin is a useful molecular marker for use in the evaluation of the progression of OSCC.

A retrospective analysis was done for 69 patients with Stage I and II non-Hodgkin's lymphoma who were treated from May 1981 to December 1990, in the Department of Radiadtion Oncology, Korea University Hospital. We used Ann Arbor Staging system and Working Formulation for histological classification. Forty-three patients (43/69, $62.3{\%}$) were Stage I and 26 patients (26/69, $37.7{\%}$) were Stage II, and B symptom was found in $10.1{\%}$ (7/69). Nodal lymphoma was $21.7{\%}$ (15/69); 14 patients with supradiaphragmatic disease and 1 patient with infradiaphragmatic disease. Extranodal lymphoma was $78.3{\%}$ (54/69): $64.8{\%}$ (35/54) for head and neck, $25.9{\%}$ (14/54) for gastrointestinal tract. Histologically, low grade consists of $8.7{\%}$ (6/69), intermediate grade $84.2{\%}$ (56/69), high grade $10.1{\%}$ (7/69), and diffuse large cell type was the most frequent form with 36 patients (36/69, $52.2{\%}$). Eighteen patients ($26.1{\%}$) were treated with radiation therapy alone,20 patients ($29.0{\%}$) with radiation therapy combined with chemotherapy, 15 patients ($21.7{\%}$) with radiation therapy combined with surgery and chemotherapy, Median survival duration was 28 months, and the range of survival time was from 1 month to 134 months. Overall five-year survival rate for Stage I and II disease was $54.2{\%}$, with $64.5{\%}$ for Stage I and $37.1{\%}$ for Stage II. For nodal lymphoma,5-year survival rate was $45.9{\%}$, and $56.5{\%}$ for extranodal lymphoma; $60.6{\%}$ for head and neck, $52.9{\%}$ for GI tract primary disease. Local control rate for all patients was $88.4{\%}$ (61/69), with $80{\%}$ (12/15) for nodal lymphoma and $90.7{\%}$ (49/54) for extranodal lymphoma. The total failure rate was $34.8{\%}$ (24/69). Five of 24 ($20.8{\%}$) patients who were failed developed local failure only, $12.5{\%}$ (3/24) local failure with distant failure, and distant failure only were found in $66.7{\%}$ (16/24). Between nodal lymphoma and extranodal lymphoma, there was no significant survival difference, but extranodal lymphoma showed higher incidence.

목적: 최근 조기건강검진에 대한 관심의 고조와 환경의 변화로 분화 갑상선암 진단 후 갑상선제거수술 및 고용량 방사성옥소 치료가 필요한 환자가 증가하고 있다. 저자들은 분화 갑상선암으로 진단 받고 갑상선제거 수술을 받은 환자에서 최초 고용량 방사성옥소 치료시 적절한 투여용량을 결정하는데 있어 병리적 병기소견이나 혈청 갑상선 글로불린치가 I-123 전신 스캔을 대신할 수 있는지를 알아보고자 하였다. 대상 및 방법: 갑상선 전절제술과 중앙 및 주변 림프절 제거술 후에 분화 갑상선암으로 진단 받은 환자 중에서 1차 고용량 방사성옥소 치료 전에 I-123 전신스캔을 시행한 58명(남:녀=13:45, 나이 $44.5{\pm}11.5$세)을 대상으로 하였다. 병리적 병기(T, N stage)는 2002 AJCC 기준에 따라 구분하였으나 나이에 따른 분류는 하지 않았다. 갑상선호르몬 중지 후 혈청 갑상선자극호르몬, 갑상선 글로불린과 갑상선글로불린항체 측정 및 I-123전신 및 국소영상(5 mCi 경구투여 후 24시간)을 얻었다. I-131 방사성옥소 치료는 I-123 스캔 결과에 따라 100 mCi에서 250 mCi 용량으로 시행하고, 치료용량과 병리적 병기, 혈청 갑상선글로불린치와의 관계를 비교하였다. 결과: I-131을 사용한 고용량 방사성옥소 치료는 5명(8.6%)에서 100 mCi, 43명(74.1%)에서 150 mCi, 6명(10.3%)에서 180 mCi. 3명(5.2%)에서 200 mCi, 1명(1.7%)에서 250 mCi로 각각 시행하였다. 병리적 병기에 따른 방사성옥소 치료용량은 stage I (n=9) $154{\pm}25\;mCi$, stage II (n=4), $175{\pm}50\;mCi$, Stage III (R=38); $149{\pm}21\;mCi$, Stage IV (n=7); $161{\pm}20\;mCi$을 보여 병리적 병기 증가와 치료용량 증가와는 유의한 상관성은 없었다. (p=0.169) 혈청 갑상선글로불린치에 따른 방사성옥소 치료용량은 2 ng/mL를 보인 군에서 $149{\pm}26 \;mCi$, 2 ng/mL이상 5 ng/mL 미만을 보인 군에서 $156{\pm}17\;mCi$, 5 ng/mL이상 10 ng/mL 미만을 보인 군에서 $156{\pm}13\;mCi$, 10 ng/mL이상 50 ng/mL 미만을 보인 군에서 $147{\pm}24 \;mCi$, 50 ng/mL이상을 보인 군에서 $175{\pm}42\;mCi$를 보여 혈청 갑상선글로불린치와 방사성옥소치료용량과는 유의한 상관성이 없었다. (p=0.252) 결론: 분화 갑상선암으로 갑상선 전절제술 후에 최초 고용량 방사성옥소 치료용량을 결정하는데 병리적 병기나 혈청 갑상선글로불린 수치가 I-123 전신 스캔을 대신하기는 어려울 것으로 생각된다.
