This study describes recent trends in incidence, survival and prevalence of subgroups of esophageal and gastric cancer in Linzhou city between 2003 and 2009. Data of esophageal and gastric cancer for the period of interest were extracted from the Linzhou Cancer Registry. Using information on tumor morphology or anatomical site, data were divided into six groups; esophageal squamous cell carcinoma, esophageal adenocarcinoma, other and unspecified types of esophageal cancer, and cardia, non-cardia, and unspecified anatomical site of stomach cancer. Incidence, survival and prevalence rates for each of the six cancer groups were calculated. The majority of esophageal cancers were squamous cell carcinomas (82%). Cardiac cancer was the major gastric cancer group (64%). The incidence of esophageal squamous cell carcinoma and gastric cardiac cancer increased between 2003 and 2009. Both esophageal and gastric cancer had a higher incidence in males compared with females. Overall survival was poor in all sub-groups with 1 year survival ranging from 45.9 to 65.6% and 5 year survival ranging from 14.7 to 30.5%. Prevalence of esophageal squamous cell carcinoma and gastric cardiac cancer was high (accounting for 80% overall). An increased focus on prevention and early diagnosis, especially in esophageal squamous cell carcinoma and gastric cardiac cancer, is required.

Aim: Esophageal cancer is the eighth most common cancer and sixth leading cause of cancer associated death worldwide. The 5 year survival rate for esophageal cancer patients is very poor and accounts for only 12.3%. Besides environmental risk factors, genetic factors might play an important role in the esophageal cancer carcinogenesis. Methods: We conducted a hospital based case-control study to evaluate the genetic effects of functional single nucleotide polymorphisms (SNPs): interleukin 9 (IL9) rs31563 C>T, IL9 rs31564 G>T, IL10 rs1800872 T>G, IL12A rs2243115 T>G, IL12B rs3212227 T>G and IL13 rs1800925 C>T on the development of esophageal cancer. A total of 380 esophageal squamous cell carcinoma (ESCC) cases and 380 controls were recruited for this study. The genotypes were determined using a custom-by-design 48-Plex SNPscan$^{TM}$ Kit. Results: The IL10 rs1800872 T>G polymorphism was associated with an increased risk of ESCC. However, there were no significant links with the other five SNPs. Stratified analyses indicated no significant risk of ESCC associated with the IL10 rs1800872 T>G polymorphism evident among any subgroups. Conclusion: These findings indicated that functional polymorphism IL10 rs1800872 T>G might contribute to ESCC susceptibility. However, our results were obtained with a limited sample size, so that the power of our analysis was low. Future larger studies with more rigorous study designs of other ethnic populations are required to confirm the current findings.

Objective: To determine whether CDX2 and villin protein expression are associated with intestinal metaplasia (IM) in gastric cardiac mucosa and to explore the relationship with evolution of gastric cardiac adenocarcinoma (GCA). Methods: We studied 143 gastric cardiac biopsy or resection specimens from Henan province China, including 25 cardiac gastritis specimens with IM, 65 dysplasia specimens with IM and 35 gastric cardiac adenocarcinoma specimens and stained them for CDX2 and villin by the immunohistochemical SP method. 15 normal gastric cardiac biopsy specimens were also collected as control. Results: (1) Normal gastric mucosa presented no CDX2 and villin expression. The positive rates of CDX2 protein in cardiac gastritis with IM, dysplasia with IM, and carcinoma tissues were 84.0% (21/25), 66.7% (32/48) and 36.4% (20/55), respectively. While the positive rates of villin protein in cardiac gastritis with IM, dysplasia with IM, and carcinoma tissues were 76.0% (19/25), 70.8% (34/48) and 45.5% (25/55), respectively. There were significant differences among the three groups for both CDX2 and villin (P<0.01). Spearman's rank correlation coefficient(rho) showed a close correlation between the two proteins (r=0.843, P<0.01) and both were positively related with tumor differentiation (both P<0.05), but not associated with age, sex, invasion and metastasis of lymph node (P>0.05). Conclusion: Our results suggest that ectopic expression of CDX2 and villin may be involved in early-stage IM and tumorigenesis in gastric cardia and the expression of villin may be regulated by CDX2.

Twenty nine adult patients underwent surgical esohpagectomy and one, bypass procedure for documented carcinoma of esophagus and cadiac portion of stomach at Chonnam National University Hospital from Jan 1986 to April 1991. There were several kinds of esophagectomies including through transhiatal, left thoracotomy only, laparotomy and thoracotomy, and laparotomy and right thoracotomy and cervical incision. Twenty five and squamous cell carcinoma and 5, adenocarcinoma. The tumor locations were the upper third in 3, middle third in 12, lower third in 10 and cardiac portion of stomach in 5. After operation, 8[27%] patients were classified in Stage IIa, 6[20%] patients in Stage IIb, 15 patients[50%] in Stage III and one patient in Stage IV. Major postoperative complications included anastomotic narrowing in 3, limited suture line leak in 2, wound infection in 2, hoarseness in 2, pseudomembraneous enterocolitis in 1 and herpes zoster in 1. There was no death within 30 days of operation. Ten months survival was 100% for patients with Stage lIa, 67% for patients with Stage IIb, 50% for patients with Stage III. Furthermore, 20 months survival was 75% in IIIa, 33% in IIb, and 40% in III. But there were no significant differences in survivals among the stage. The actuarial survival is 58% at one year and 41% at two years, The periods of average survival is 589 days after operation.

식도암의 수술 시 고령은 수술 합병증 및 사망의 고위험인자로 알려져 있다. 그러나, 최근 들어 수술 술기와 수술 전후 환자 관리의 발전으로 고령의 식도암 환자에서도 식도절제술 후 합병증 및 사망률이 많이 감소하였다. 이 연구는 70세 이상의 식도암환자에서 식도절제술 및 재건술 후 결과를 70세 미만의 군과 비교 분석하고자 하였다. 대상 및 방법: 2001년 3월부터 2004년 7월까지 국립암센터 폐암센터에서 식도암으로 식도절제술 및 재건술을 시행한 174명의 환자를 대상으로 후향적 분석을 하였다 환자를 70세 이상$(제1군,\;n=27,\;15.5\%)$과 70세 미만$(제2군,\;n=147,\;84.5\%)$으로 나누어 수술전 상태, 수술 후 합병증 발생, 수술 사망 및 생존율을 비교 분석하였다. 결과 : 환자들의 연령은 평균 63_4세였으며, 남자가 159명이었다. 병리조직 소견은 $93.1\%$가 편평상피세포암이었다. 병변의 위치는 $78.8\%$에서 중부 및 하부 식도였다. 근치적 절제는 162명$(93.1\%)$에서 가능하였다 평균 재원기간은 19.4일이었으며, 두 군간에 차이는 없었다. 수술 후 합병증은 61명$(35.1\%)$에서 발생하였다. 이 중 호흡기계 합병증이 33예$(19.0\%)$로 가장 많이 발생하였다. 제1군에서 수술 전 고혈압 및 심장과 폐기능의 저하가 더 많았으나(p=0.064, p=0.002, p=0.057), 수술 후 합병증 발생률에는 두 군간에 차이가 없었다$(44.4\%\;vs.\;33.3\%,\;p=0.28)$. 수술 사망은 7명$(4.0\%)$이었으며, 두 군간에 차이가 없었다$(3.7\%\;vs.\;4.1\%)$. 평균 생존은 26.5개월로, 1년 생존율 $81.0\%$, 3년 생존율은 $40.5\%$이었고, 생존율은 두 군간에 차이가 없었다(p=0.64). 걸론: 70세 이상의 식도암 환자에서 만족스러운 조기 결과로 안전하게 식도절제술 및 재건술을 시행할 수 있었다. 따라서 고령의 식도암 환자에서도 식도 절제술 및 재건술을 적극적으로 고려해야 할 것이다.

To evaluate the value of combined detection of serum CEA, CA19-9, CA24-2, AFP, CA72-4, SCC, TPA and TPS for the clinical diagnosis of upper gastrointestinal tract (GIT) cancer and to analyze the efficacy of these tumor markers (TMs) in evaluating curative effects and prognosis. A total of 573 patients with upper GIT cancer between January 2004 and December 2007 were enrolled in this study. Serum levels of CEA, CA19-9, CA24-2, AFP, CA72-4, SCC, TPA and TPS were examined preoperatively and every 3 months postoperatively by ELISA. The sensitivity of CEA, CA19-9, CA24-2, AFP, CA72-4, SCC, TPA and TPS were 26.8%, 36.2%, 42.9%, 2.84%, 25.4%, 34.6%, 34.2% and 30.9%, respectively. The combined detection of CEA+CA199+CA242+CA724 had higher sensitivity and specificity in gastric cancer (GC) and cardiac cancer, while CEA+CA199+CA242+SCC was the best combination of diagnosis for esophageal cancer (EC). Elevation of preoperative CEA, CA19-9 and CA24-2, SCC and CA72-4 was significantly associated with pathological types (p<0.05) and TNM staging (p<0.05). Correlation analysis showed that CA24-2 was significantly correlated with CA19-9 (r=0.810, p<0.001). The levels of CEA, CA19-9, CA24-2, CA72-4 and SCC decreased obviously 3 months after operations. When metastasis and recurrence occurred, the levels of TMs significantly increased. On multivariate analysis, high preoperative CA72-4, CA24-2 and SCC served as prognostic factors for cardiac carcinoma, GC and EC, respectively. combined detection of CEA+CA199+CA242+SCC proved to be the most economic and practical strategy in diagnosis of EC; CEA+CA199+CA242+CA724 proved to be a better evaluation indicator for cardiac cancer and GC. CEA and CA19-9, CA24-2, CA72-4 and SCC, examined postoperatively during follow-up, were useful to find early tumor recurrence and metastasis, and evaluate prognosis. AFP, TPA and TPS have no significant value in diagnosis of patients with upper GIT cancer.
