Abstract
OBJECTIVE To investigate the epidemiological characteristics and identify the risk factors of Giardia lamblia infections among patients with colorectal cancer in Henan Province. METHODS A cross-sectional study was performed for questionnaire surveys among colorectal cancer patients in Henan Cancer Hospital during the period from March to July, 2021. Patients' stool samples were collected, and the triosephosphate isomerase (tpi) gene of G. lamblia was amplified in stool samples using nested PCR assay to characterize the parasite genotype. Univariate analysis and multivariate logistic regression analyses were employed to identify the risk factors of G. lamblia infections among colorectal cancer patients. RESULTS A total of 307 colorectal cancer patients were investigated, including 176 males (57.3%) and 131 females (42.7%). PCR assay detected 8.1% [95% confidential interval (CI): (0.056, 0.117)] prevalence of G. lamblia infections among the study subjects, and there was no significant difference in the prevalence between men [9.1%, 95% CI: (0.057, 0.143)] and women [6.9%, 95% CI: (0.037, 0.125)] (χ2 = 0.495, P = 0.482). In addition, there was no age-specific prevalence of G. lamblia infections among the participants (χ2 = 1.534, P = 0.675). Multivariate logistic regression analysis identified use of septic tanks [odds ratio (OR) = 3.336, 95% CI: (1.201, 9.267)], daily use of well water [OR = 3.042, 95% CI: (1.093, 8.465)] and raising livestock [OR = 3.740, 95% CI: (1.154, 12.121)] as risk factors of G. lamblia infections among colorectal cancer patients, and the prevalence of abdominal pain was significantly greater in colorectal cancer patients with G. lamblia infections than in those without infections (P = 0.017). Among the 25 patients with G. lamblia infections, assemblage A was characterized in 24 (96.0%) cases and assemblage B in one case (4.0%). CONCLUSIONS The prevalence of G. lamblia is high among colorectal cancer patients in Henan Province, and assemblage A is the dominant genotype of G. lamblia. Use of septic tanks, daily use of well water and raising livestock are risk factors of G. lamblia infections among patients with colorectal cancer.

Abstract
OBJECTIVE To investigate the advantages of thoracoabdominal radical gastrectomy for advanced Siewert type Ⅱ adenocarcinoma of the esophagogastric junction. METHODS Clinical data of 86 patients with Siewert type Ⅱ adennocarcinoma of the esophagogastric junction who received surgical treatment at the Henan Provincial Tumor Hospital from January 2015 to January 2016 were retrospectively analyzed. Among them, 44 patients underwent abdominal operation (abdominal group), and 42 patients underwent thoracoabdominal radical gastrectomy (thoraco-abdominal group). The operation time, lymph node number, distance between the tumor and cutting edge, amount of intraoperational blood loss, postoperative pulmonary complications, and postoperative hospital stay in the two groups were compared. RESULTS Comparing the thoracoabdominal group with the abdominal group, the number of removed lymph nodes was 41.57±9.22 vs. 35.09±10.61 (P<0.01), the number of removed mediastinal lymph nodes was 6.38±1.50 vs. 3.52±1.42 (P<0.01), the distance between the tumor and cut edge was (5.62±0.73) cm vs. (3.30±0.85) cm (P<0.01), whereas the operation time, intraoperative blood loss, postoperative pulmonary complications, occurrence of anastomotic leakage and hospital stay were statistically not significantly different (P>0.05 for all). CONCLUSIONS For patients with advanced Siewert type Ⅱ adenocarcinoma of the esophagogastric junction, radical gastrectomy through thoracoabdominal approach can resect a longer segment of the esophagus, dissect more mediastinal lymph nodes, and does not increase post-operative complications and extend hospital stay, thus, exhibits obvious advantages in the surgical treatment of Siewert Ⅱ adenocarcinoma of the esophagogastric junction.
