Esophageal fistulas may occur in an advanced stage or as a potentially life-threatening complication of treatment. They can be divided into esophageal-respiratory and esophageal-aorta fistulas. The diagnosis is confirmed with fluoroscopy using dilute barium oral contrast, followed by thin-section computed tomography, which defines the precise location and extent of the fistula. Flexible esophagoscopy and bronchoscopy are required for confirmation and anatomic assessment of the suspected fistula and provide additional information for treatment planning. Contamination is traditionally controlled by surgical exclusion, along with a jejunal feeding tube. Currently, fully covered self-expanding metal stents are the primary treatment option.

Background: Esophageal squamous cell carcinoma (ESCC) is a common cancer in the north east of India. The present study concerned the prevalence of human papilloma virus (HPV) in the ESCC in north eastern India and its impact on response to chemotherapy. Materials and Methods: p16 expression, a surrogate marker for HPV infection was assessed in 101 pre-treatment biopsies of locally advanced ESCC, reported from a comprehensive cancer centre in north east India, using immunohistochemistry. All patients received neo-adjuvant chemotherapy. Response was assessed clinically and histopathologically with attention to p16 expression. Results: p16 was expressed in 22% of ESCC (22 out of 101) and was more prevalent in patients who were more than 45 years of age (P=0.048). p16 positive tumors appeared more commonly in the upper 2/3 of the thoracic esophagus (18 in 22). Nine of the 22 (41%) p16 positive tumors achieved pathologic complete response following neo-adjuvant chemotherapy (P=0.008). There was a trend towards reduced mortality in this group (P=0.048). Some 9 of the 20 (45%) patients who achieved pathologic complete response were p16 positive. Conclusions: Expression of p16 in ESCC correlates with higher rate of pathologic complete remission in patients undergoing neo adjuvant chemotherapy and could be a predictive marker for response assessment.

Esophagogastric junction (EGJ) cancer is a solid tumor entity with rapidly increasing incidence in the Western countries. Given the high proportion of advanced cancers in the West, treatment strategies routinely employed include surgery and chemotherapy perioperatively, and chemoradiation in neoadjuvant settings. Neoadjuvant chemoradiation and perioperative chemotherapy are mostly performed in esophageal cancer that extends to the EGJ and gastric as well as EGJ cancers, respectively. Recent trials have tried to combine both strategies in a perioperative context, which might have beneficial outcomes, especially in patients with EGJ cancer. However, it is difficult to recruit patients for trials, exclusively for EGJ cancers; therefore, the results have to be carefully reviewed before establishing a standard protocol. Trastuzumab was the first drug for targeted therapy that was positively evaluated for this tumor entity, and there are several ongoing trials investigating more targeted drugs in order to customize effective therapies based on tissue characteristics. The current study reviews the multimodal treatment concept for EGJ cancers in the West and summarizes the latest reports.

Background: Areas of Iran have among the highest incidences of esophageal cancer in the world. Definitive chemo-radiotherapy (DCRT) is used for locally advanced esophageal cancer and for inoperable tumors asan alternative to surgical treatment. Materials and Methods: This retrospective study was conducted in North-West Iran 2006-2011, including 267 consecutive patients with non-metastatic esophageal cancer. Eligible inoperable patients were treated with DCRT or definitive radiotherapy (DRT) alone. Radiotherapy (RT) was delivered at 1.8-2 Gy/day for five consecutive days in a given week. Chemotherapy (CT) consisted of cisplatin and 5-fluorouracil. Results: The median survival was 12.7 months with 1, 3 and 5 year survival rates of 55%, 18% and 11%, respectively. On univariate analysis, relations with age at diagnosis (p=0.015), N-stage (p=0.04), total dose of RT (p=0.001), fraction (p<0.001), Gap status (p=0.025), chemotherapeutic regimens (P=0.027), and 5-Fu $Mg/m^2$ (P=0.004) were apparent. Comparing DCRT to DRT, there was a significant difference in survival. Multivariate analysis was performed for comparison between DCRT and DRT showed significant association with age group ${\geq}65$ to <65 (P=0.02; OR: 1.46), the total RT dose (Gy) ${\geq}50$ to <50 (P=0.01; OR: 0.65) and the fraction group ${\geq}25$ to <25 (P=<0.001; OR: 0.54). Conclusions: The survival rates of esophageal cancer treated with DCRT in North West of Iran is poor; therefore, early detection and improved treatment methods, with clinical trials are a high priority.

Background: Esophageal cancer is one of the most frequently occurring malignancies and the seventh leading cause of cancer-related deaths in the world. The esophageal squamous cell carcinoma (ESCC) is the most common histological type of esophageal cancer worldwide. Materials and Methods: Our goal in this study was to detect phospholipase A2 Group IIA (PLA2G2A) and cyclooxygenase-2 (COX-2) immuno-expression in ESCC in a high-risk population in China. Results: Positive expression of PLA2G2A protein was observed in 57.2% (166/290) of the cases, while COX-2 was found in 257 of 290 samples (88.6%), both PLA2G2A and COX-2 being expressed in 153 cases (52.8%), with a significant agreement (Kappa=0.091, p=0.031).Overexpression of PLA2G2A was significantly correlated with the depth of invasion (p=0.001). Co-expression of PLA2G2A and COX-2 not only significantly correlated with the depth of invasion (p=0.004) but also with TNM stage (p=0.04). Conclusions: Our results showed that in patients with ESCC, PLA2G2A overexpression and PLA2G2A co-expression with COX-2 is significantly correlated with advanced stage. The biological role and pathophysiologic regulation of PLA2G2A and COX-2 overexpression in ESCC deserve further investigation.

한국에서는 식도암의 임상적 관찰과 치료성적이 아직까지는 광범위하게 연구 및 보고되지 않았지만, 소화기계통에서 발생하는 악성종양 중에서는 비교적 적지 않은 것으로 알려져 있다. 의학적 지식, 진단적 설비, 방사선 치료의 적용, 외과적 수술의 진보, 그리고 최근의 화학요법의 재발 등과 같은 괄목할만한 향상에도 불구하고 예후는 극히 불량하여 5년 생존율이 10%이하로서, 과거에 비하여 크게 향상되지 않은 것으로 보고되고 있다. 이에 저자들은 1970년 1월부터 1980년 12월까지 만 11년 동안 식도암으로 진단되어 연세 암 센터에서 근치적 목적으로 방사선 치료를 받았던 63예에 대한 철저한 추적조사를 통하여 후향성 분석을 시행한 바 다음과 같은 결과를 얻었다. 1. 전 63예의 식도암 환자의 85.2%인 52예는 조직병리학적 소견에서 상피성세포암(Epidermoid Carcinoma)으로 확진되었다. 그리고 $T_1$인 17예를 제외한 46예73%의 병변은 상당히 진행되였던 예들이였다. 2. 방사선 조사선량은 일일 일회 2Gys가 조사되였으며 총 조사선량 $50{\sim}74Gys$가 $5{\sim}8$주간에 조사되었다. 3. 전 63예중 28예에서 방사선 치료 후 1개월만에 식도조형상을 통하여 식도암에 대한 방사선치료 효과를 평가하여 본 결과, 완전관해는 7예였으며 나머지 15예는 부분적 관해, 그리고 6예는 변화가 없었다. 4. 전 63예의 3년, 5년 생존율은 11.8%, 8.8%였으며 그리고 $T_1$인 17예의 3년, 5년 생존율은 24.7%, 20.8%였다.

목 적: 동시적 항암화학방사선치료를 받은 식도암 환자의 치료성적과 예후인자를 분석하였다. 대상 및 방법: 1994년 1월부터 2007년 7월까지 식도암으로 방사선치료를 받은 환자 246명 중 근치적 목적으로 45Gy이상의 방사선치료와 함께 동시적 항암화학요법을 받았으며 생존확인이 가능하였던 78명을 대상으로 후향적 분석을 시행하였다. AJCC 병기 IIA~IVB까지의 환자를 대상으로 하였는데, IVB는 상부식도암이 아닌 환자에서 쇄골상부림프절 전이가 있거나 하부식도암이 아닌 환자에서 복강림프절 전이가 있는 경우만을 포함시켰다. 방사선치료는 중앙값 54 Gy를 조사하였고, 항암화학요법은 대부분의 환자(88%)에서 5-FU와 cisplatin (FP) 병합요법으로 시행되었다. 추적관찰기간은 2~117개월(중앙값 14개월)이었다. 결 과: 흉부단층촬영이나 식도내시경을 통해 치료에 대한 반응을 확인할 수 있었던 54명의 환자중 완전관해가 17명, 부분관해가 18명이었다. 완전관해를 보인 환자에서 재발할 때까지의 기간은 중앙값 20개월이었고 첫 재발부위로 국소재발이 3명, 원격전이가 7명이었다. 1년, 2년, 5년 전체 생존률은 각각 58.9%, 21.7%, 12.2%이었고 중앙 생존기간은 14개월이었다. 전체 생존률에 대한 단변량분석에서 치료에 대한 반응과 FP병합요법의 횟수가 통계적인 유의성을 보여주었다. 환자의 숫자가 적었으나 방사선감작제로 일단위 혹은 주단위의 cisplatin이 FP 병합요법보다 좋은 결과를 보였다. 결 론: 원격장기로의 전이가 없는 국소진행성 식도암 환자에서 동시적 항암화학방사선치료는 기존의 연구와 유사한 결과를 보여주었다. 일단위 혹은 주단위의 cisplatin이 전신상태가 FP 병합요법에 적절하지 않은 환자에서 대안으로 사용될 수 있을 것으로 생각된다.
