The aim of this study was to investigate QoL (quality of life) of patients with esophageal cancer in northern Henan province, China, and to accurate evaluate and reflect the relationship between patient characteristics and QoL. In the high risk area of esophageal cancer in the north of Henan province, 735 patients with esophageal cancer were investigated. The Eysenck personality questionnaire (EPQ) and QoL were analyzed by using the questionnaire of general situation, EPQ, QLQ-C30 and QLQ-OES18. The effects of personal character on the QoL of esophageal carcinoma patients were analyzed by SPSS 11.0 software. The QoL of esophageal cancer patients in Northern Henan region was significantly affected by character. The difference between choleric and type of melancholic temperament types was significant (P<0.01), also in OESEAT, OESTA, OESCO and OESSP (P<0.05). Differences in personal character can thus influence the quality of esophageal cancer patient lives.

식도에서 간엽세포 종양과 상피성세포 종양의 공존은 매우 드물다 저자들은 식도 평활근종의 점막표면에 위치한 편평상피세포암 수술 치험 1예를 보고한다. 내원 3개월 전부터 음식 섭취시 연하통을 주소로 내원한 76세 남자 환자에서 수술 전 검사로 석회화를 동반한 식도 점막하종양을 의심하였고, 종양을 덮고 있는 불규칙한 점막의 식도내시경 조직검사로 편평상피세포암의 공존을 수술 전에 진단하였다. 우측 개흥과 개복으로 흉부 식도절제술 후 식도-위 문합을 시행하였다. 수술 25개월이 경과한 현재까지 재발의 소견 없이 정상 생활을 하고 있다. 두 종양 사이의 관계의 가능성과 빈도에 대해 문헌 고찰을 한다.

For patients with neck and upper thoracic esophageal carcinoma, it is difficult to control lymph node metastases with conventional dose therapy. In this study, we assessed the feasibility of simplified intensity-modulated radiotherapy (sIMRT) and concurrent chemotherapy for 44 patients and boosted high-dose to metastatic lymph nodes. Three radiation treatment volumes were defined: PGTVnd, with which 68.1Gy was delivered in high dose group (hsIMRT group), and 60Gy in the conventional dose group (csIMRT group); PTV1, featuring 63.9Gy in the hsIMRT group and 60Gy in the csIMRT group; PTV2, with 54Gy given to both groups. The sIMRT plan included 5 equi-angular coplanar beams. All patients received the cisplatin and 5-FU regimen concurrently with radiotherapy. The treatment was completed within six weeks and one case with grade three acute bronchitis was observed in hsIMRT group. For esophageal lesions, 80% complete response (CR) and 20% partial response (PR) rates were found in the hsIMRT group, and 79.2% CR, with 20.8% PR, in the csIMRT group; for lymph node lesions, 75% CR and 25% PR rates were observed in the hsIMRT group, with 45.8% and 37.5% respectively in the csIMRT group (P<0.05). The differences in 1-, 2- and 3-year relapse-free survival rates were all statistically significant (P<0.05). The major toxicity observed in both groups was Grade I~II leucopenia. sIMRT can generate a desirable dose distribution in treatment of neck and upper thoracic esophageal carcinoma with a better short-term efficacy. Boosted high dosing to metastatic lymph nodes can increase the relapse-free survival rate.

Adenoid cystic carcinoma of the esophagus has been relatively an uncommon, slow growing tumor. A 51 year-old man patient had a tumor in the lower third of the esophagus which was incidentally found during an examination for UPPER C-I series, and resected successfully without Thoracotomy. The tumor exhibited a polypoid appearance covered by normal esophageal epithelium, localized entirely in the submucosal layer of the esophagus and morphologically identical to adenoid cystic carcinoma in the salivary glands.

Background; Surgical resection remains the mainstay of treatment for esophageal cancer. Despite recent advances in surgical therapy, i.e. en bloc resection and extended lymphadenectomy, the overall long-term prognosis of patients with esophageal carcinoma has not, however, improved during the last decades. One of the major reasons in its relatively high recurrence rate. Material and Method; A retrospective review of recurrent patte군 of cancer in 42 patients who underwent curative surgery for primary esophageal cancer was performed clinically and histo-phthologically. Result; Nineteen patients had developed recurrece during the 18 to 52 months(mean 34.2 nonths), 8 had local recurrences, 1 had both, and 11 had systemic recurrences. Twelve patients(63%) had developed recurrence within 1 year, 5 patients(26%) between 1 year to 2 patients(11%) after 2 years. The recurrence rate according to growth pattern of tumor or presence of microinvasive findings was not statistically significant, but it increased significantly in clinical tumor stage III than stage IIA, B and in patients with the number of metastatic lymph node over ten. Conclusion; Post-operative recurrences of esophageal cancer appear as a high rate even though curative wide resection was done. Several clinical and histo-pathological factors correlate with the recurrence.

식도 재건술을 시행한 뒤에 발생하는 문합부의 협착은 비교적 드물지만 환자와 의료진에게 반갑지 않은 이다. 이에 대한 해결책으로 풍선확장술, 협착부에 대한 재수술 또는 심한 경우 식이용 장루술이 고려된다. 그러나 풍선확장술의 경우 단기간내 재발의 확률이 높고, 썩 효과적이지 않으며, 협착부에 대한 재수술은 수술적 접근이 쉽지 않고 재협착의 가능성 배제가 어려우며, 식이용 장루술의 경우 경구식이가 불가능하다는 어려운 점들이 있다. 이에 2001년 1월부터 2001년 12월까지 식도스텐트를 이용하여 문합부 협착의 완화를 시도하였다. 1예는 양성협착의 수술이었고 2예는 악성종양이었다 약 1년이상의 추적관찰을 하였고 연하곤란은 개선되었다. 이에 식도 스텐트를 이용한 술후 문합부 협착의 임상적 호전에 대하여 증례를 보고하고자 한다.

Objective: To investigate the association between xeroderma pigmentosum group D (XPD) Asp312Asn polymorphism and esophageal cancer (EC) susceptibility by meta-analysis. Methods: We searched PubMed up to April 9th, 2012, to identify relevant papers, and 8 published case-control studies including 2165 EC patients and 3141 healthy controls were yielded. Odds ratios (ORs) with relevant 95% confidence intervals (CIs) were applied to assess the association between XPD Asp312Asn polymorphism and EC susceptibility with the Comprehensive Meta-Analysis software, version 2.2. Results: Overall, the meta-analysis results suggested the XPD Asp312Asn polymorphism to be significantly associated with EC susceptibility [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.20, 95%CI=1.05-1.36, p=0.01; and Asp/Asn vs. Asp/Asp: OR=1.15, 95%CI =1.01-1.31, p=0.04]. In the subgroup analysis by ethnicity and cancer type, significantly associations were found for Caucasian populations [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.26, 95%CI =1.08-1.47, p<0.001; Asp/Asn vs. Asp/Asp: OR=1.19, 95%CI =1.02-1.40, p=0.03] and esophageal squamous cell carcinoma [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.19, 95%CI=1.01-1.41, p=0.04]. There was no heterogeneity and no publication bias existed. Conclusions: This meta-analysis shows that the XPD Asp312Asn polymorphism may be a risk factor for developing EC, especially for Caucasian populations and esophageal squamous cell carcinoma.

배경: 악성종양에서 신생혈관 생성 및 당분해의 증가는 저산소 상태의 미세환경을 나타내며, 이는 종양의 침습성, 전이 등으로 환자의 예후와 관련이 있는 것으로 알려져 있다. Hypoxia-inducible factor 1(HIF-1)는 당원 수송체, 당분해 효소, 혈관내피세포 성장인자 등의 유전자의 전사를 활성화한다고 알려져 있다. 그리고 HIF-1의 전사 활성도는 HIF-1 a subunit의 표현이 조절되는 정도에 의존한다. 그러나 식도암에서 HIF-1의 발현과 혈관 생성능 및 종양세포 증식능과의 관계 및 예후에 관한 연구는 전무하다. 대상 및 방법: 고신대학교 의과대학 흉부외과학교실에서 1995년부터 2000년까지 수술치험한 77예의 식도 편평세포암 환자의 조직에서 채취한 정상 편평상피와 암조직에서 면역조직화학검사를 이용하여 HIF-1 a의 발현을 조사하고 혈관생성인자, 증식지수, p53 단백과의 상관관계, 임상-병리학적인 인자 및 생존율과의 상관관계를 분석하였다. 결과: HIF-1 a의 고발현율은 42.9% (33예/77예)였다. HIF-1 a의 고발현은 조직학적 등급(p=0.032), 병리학적 병기(p=0.002), 종양 침윤의 깊이(p=0.022), 주위 림프절 전이(p=0.002), 원격전이(p=0.049), 림프관 침윤(p=0.004)과 관련이 있었다. HIF-1 a의 고발현은 혈관내피세포 성장인자의 발현, Ki-67 증식지수와 관련이 있었으나, 미세혈관수와는 관련이 없었고, p53의 발현과는 관련이 있는 경향을 보였다. 단변량분석과 다변량분석에서 HIF-1 a의 고발현은 불량한 예후를 나타내는 인자로 보였다. 결론: 식도 편평세포암 조직에서 HIF-1 a의 발현은 종양조직내 신생혈관의 생성과 관련이 있는 것으로 나타났고, 고발현 된 경우는 림프절 전이와 수술 후 불량한 예후를 나타내었으므로 보다 강화된 치료전략이 필요할 것으로 사료된다.

One mid-esophageal carcinoma underwent esophagogastrectomy using an exclusive right thoracic approach entailing mobilization of the stomach through the esophageal hiatus. 62 year old male farmer was admitted with chief complaints of dysphagia and weight loss of 5 Kg. for 6 months, and regurgitation after soft meal for one week prior to this admission. Preoperative esophagogram revealed stricture with fungating mass at the level of the carina, which was diagnosed as squamous cell carcinoma at the time of esophagoscopic biopsy about 33 cm from incisor. Bronchoscopy revealed no invasive lesion or carinal fixation, and laboratory examinations were excellent for operative intervention. An exclusive right thoracic approach through right 5th rib bed was made for radical esophagectomy, mobilization of the stomach through the esophageal hiatus and primary esophagectomy. Postoperative recovery was uneventful except increased bronchial secretion due to senile emphysema, and follow up for 5 months after esophagectomy revealed good functioning esophagus with mild epigastric fullness after meal. Exclusive right thoracic approach for radical esophagectomy seems to be the procedure of choice in selected cases.
