Curcumae Rhizoma, derived from the rhizome of Curcuma phaeocaulis, Curcuma kwangsiensis and Curcuma wenyujin, was called Ezhu in China. In the past, Curcumae Rhizoma extracts were obtained through water decoction or alternative methods, which showed significant anti-cancer effects. However, the mixed extracts contain various compound components of Curcumae Rhizoma, leading to an ambiguous mechanism of action for Curcumae Rhizoma extracts anti-cancer. Contemporary researchers have extracted the chemical components of Curcumae Rhizoma separately for experimental verification of its active ingredients in the anti-cancer field. Numerous studies demonstrated that curcumol, germacrone, β-elemene, and curcumin in Curcumae Rhizoma extracts have significant governing effects in anti-cancer activities. Pharmacological studies have shown that Curcumae Rhizoma suppresses cancer cell proliferation, invasion, and migration, triggering apoptosis and regulating cellular autophagy to achieve anticancer effects. Here, we summarized the research progress of Curcumae Rhizoma on anti-cancer effects from 2013 to 2022, aiming to explore the deeper molecular mechanisms of Curcumae Rhizoma's active components in cancer treatment.

Objective:To study the impact of the age-adjusted Charlson comorbidity index (ACCI) on the prognosis of patients with hilar cholangiocarcinoma following laparoscopic surgical resection.Methods:Clinical data of 136 patients with hilar cholangiocarcinoma undergoing laparoscopic surgery at Zhengzhou University People's Hospital between January 2013 and January 2018 were retrospectively analyzed, including 81 males and 55 females, aged (63.6±9.8) years. Patients were divided into two groups based on the median ACCI score of 4.0: the high ACCI group (ACCI>4.0, n=49) and low ACCI group (ACCI≤4.0, n=87). The prognosis was compared between the two group. Univariate and multivariate Cox regression analyses were performed to analyze the effect of ACCI on survival after laparoscopic surgery. Results:The 1- and 3-year cumulative survival rates in low ACCI group were 87.4% and 48.3%, respectively, compared to 53.1% and 4.1% in high ACCI group ( χ2=27.97, P<0.001). Univariate Cox regression analysis indicated that ACCI >4.0 was associated with prognosis ( HR=3.73, 95% CI: 2.44-5.68, P<0.001). Multivariate Cox regression analysis also indicated that ACCI >4.0 was associated with an increased risk of postoperative mortality in patients with hilar cholangiocarcinoma ( HR=2.69, 95% CI: 1.65-4.37, P<0.001). Conclusion:The ACCI is a significant risk factor for survival of patients with hilar cholangiocarcinoma following laparoscopic surgery, which could facilitate a precise preoperative assessment of patient status and choice of surgical approach.

Objective:To compare the short-term clinical outcomes of patients undergoing laparoscopic versus open radical resection of hilar cholangiocarcinoma.Methods:The clinical data of 91 patients who underwent radical resection for hilar cholangiocarcinoma at our hospital from January 2018 to June 2021 were analyzed retrospectively. There were 48 males and 43 females, with aged of (61.51±7.18) years old. The patients were divided into the laparotomy group ( n=59) and the laparoscopic group ( n=32) based on the operations they received. The general data, perioperative data and complications of the two groups were compared. Results:There was no perioperative death in the laparoscopic group, but one patient died of abdominal bleeding in the laparotomy group. All other patients recovered from postoperative complications with treatment. When compared with patients in the laparotomy group, the operation time [(381.28±102.37) vs. (296.81±84.74) min] and biliary intestinal anastomosis time [(17.81±2.81) vs. (15.19±2.27) min] were significantly longer in the laparoscopic group. However, the postoperative hospital stay [(12.34±3.46) vs. (15.10 ± 4.48) d], bed rest time [(3.38±0.66) vs. (5.24±0.88) d], analgesic time [(4.31±0.90) vs. (6.22±1.26) d] and postoperative time to first feeding [(3.91±0.89) vs. (5.32±0.86) d] were significantly lower ( P<0.05). There were no significant differences in amounts of intraoperative bleeding, numbers of lymph node harvested and incidences of postoperative complications between groups ( P>0.05). Conclusion:Under the premise of strictly indications, laparoscopic radical resection of hilar cholangiocarcinoma was safe and feasible, and had certain advantages in promoting the rapid recovery of patients.

Objective:To investigate the application value of peripheral blood circulating tumor cell (CTC) classification in the prediction of preoperative microvascular invasion of hepato-cellular carcinoma (HCC).Methods:The retrospective case-control study was conducted. The clinico-pathological data of 102 HCC patients who were admitted to Zhengzhou University People's Hospital from September 2018 to September 2020 were collected. There were 71 males and 31 females, aged from 29 to 80 years, with a median age of 57 years. Observation indicators: (1) surgical situations; (2) results of CTC detection and microvascular invasion in HCC patients; (3) results of CTC classification and the best cut-off value of CTC classification in the prediction of microvascular invasion in HCC; (4) influencing factors for microvascular invasion in HCC; (5) comparison of clinicopathological features in HCC patients with different cell counts in mesenchymal phenotype of CTC (M-CTC). Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and comparison between groups was analyzed using the nonparametric rank sum U test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. The receiver operating characteristic (ROC) curve was used to determine the best cut-off value for the risk of microvascular invasion in patients. Univariate and multivariate analysis were performed using the Logistic regression model. Results:(1) Surgical situations. All 102 patients underwent surgery successfully, including 17 cases undergoing local hepatectomy, 43 cases under-going segmentectomy, 22 cases undergoing hepatic lobectomy, 13 cases undergoing hemilectomy and 7 cases undergoing enlarged hemilectomy. The operation time and the volume of intraoperative blood loss were 235(147,293)minutes and 300(110,500)mL of the 102 patients, respectively. (2) Results of CTC detection and microvascular invasion in HCC patients. Of 102 patients, there were 36 casas with epithelial phenotype of CTC (E-CTC), 86 cases with hybrid phenotype of CTC (H-CTC), 30 cases with M-CTC, respectively, and the total CTC (T-CTC) were positive in 89 cases. Results of postoperative pathological examination showed that there were 40 cases with micro-vascular inva-sion and 62 cases without microvascular invasion in the 102 patients. Of the 40 patients with micro-vascular invasion, the count of E-CTC, H-CTC, M-CTC and T-CTC were 0(0,1) per 5 mL, 4(2,5) per 5 mL, 1(0,2) per 5 mL and 5(3,8) per 5mL, respectively. The above indicators of the 62 cases without microvascular invasion were 0(0,1) per 5 mL, 3(1,5) per 5 mL, 0(0,0) per 5 mL and 3(2,6) per 5 mL, respectively. There were significant differences in the count of M-CTC and T-CTC between patients with and without microvascular invasion ( Z=-4.83, -2.96, P<0.05). (3) Results of CTC classi-fication and the best cut-off value of CTC classification in the prediction of microvascular invasion in HCC. The ROC curve showed that best cut-off value of M-CTC and T-CTC counts in the prediction of microvascular invasion in HCC were 1 per 5 mL and 4 per 5 mL, respectively, with the area under curve, the corresponding specificity, sensitivity were 0.70 (95% confidence interval as 0.60-0.81, P<0.05), 75.8%, 62.9% and 0.67 (95% confidence interval as 0.57-0.78, P<0.05), 60.0%, 72.5%, respec-tively. (4) Influencing factors for microvascular invasion in HCC. Result of univariate analysis showed that alpha fetoprotein (AFP), aspartate aminotransferase (AST), tumor diameter, tumor number, tumor margin, Barcelona clinic liver cancer staging, M-CTC counts and T-CTC counts were related factors influencing microvascular invasion in HCC ( odds ratio=3.13, 0.43, 4.92, 5.65, 2.54, 2.93, 8.25, 4.47, 95% confidence interval as 1.34-7.33, 0.19-0.98, 2.09-11.58, 2.35-13.63, 1.13-5.75, 1.27-6.74, 3.13-21.75, 1.88-10.61, P<0.05). Result of multivariate analysis showed that tumor diameter >5 cm, tumor number as multiple and M-CTC counts ≥1 per 5 mL were independent risk factors influencing microvascular invasion in HCC ( odds ratio=2.97, 4.14, 4.36, 95% c onfidence interval as 1.01-8.70, 1.14-15.02, 1.36-13.97, P<0.05). (5) Comparison of clinicopathological features in HCC patients with different cell counts in M-CTC. The 102 HCC patients were divided into the high M-CTC group of 30 cases with M-CTC counts ≥1 per 5 mL and the low M-CTC group of 72 cases with M-CTC counts <1 per 5 mL, according to the best cut-off value of M-CTC counts. Cases with hepatitis, cases with AFP >400 μg/L, cases with AST >35 U/L, cases with irregular tumor margin, cases with tumor diameter >5 cm, cases with tumor number as multiple and cases with micro-vascular invasion were 22, 17, 13, 21, 18, 16 and 22 in the high M-CTC group of 30 cases. The above indicators were 35, 18, 48, 26, 25, 21 and 18 in the low M-CTC group of 72 cases. There were significant differences in the above indicators between the high M-CTC group and the low M-CTC group ( χ2=5.25, 9.42, 4.80, 9.79, 5.55, 5.35, 20.75, P<0.05). Conclusions:The epithelial-mesen-chymal phenotype of peripheral blood CTC can be used to predict the preoperative microvascular invasion in HCC. Tumor diameter >5 cm, tumor number as multiple and M-CTC counts ≥1 per 5 mL are independent risk factors influencing microvascular invasion in HCC patients.

Objective:To investigate the value of tumor budding in the clinicopathology and prognosis of pancreatic neuroendocrine tumors.Methods:The Cliniccal data of 105 pancreatic neuroendocrine tumor patients underwent resection in Henan Provincial People's Hospital from Jan 2010 to Dec 2016 were retrospectively analyzed. Tumor budding was calculated through hematoxylin-eosin (HE) and immunohistochemical stained slides. Based on the receiver operating characteristic curve (ROC), the number of tumor budding ≥10 was defined as the high-grade budding group, and <10 as the low-grade budding group. Multiple analysis was performed to determine the relationship between tumor budding and clinicopathology as well as prognosis.Results:High-grade budding group was observed in 35 cases and low-grade group in 70. High-grade budding were more common in tumors with advanced T stage, high risk of lymphatic metastasis, preoperative liver metastasis, vascular invasion and postoperative recurrence (respectively χ 2=9.043, 4.286, 10.130, 12.090, 9.260, all P<0.05). Multivariate COX regression analysis showed that tumor budding ( P=0.018), tumor grade ( P=0.026), preoperative liver metastasis ( P=0.042), vascular invasion( P=0.048) was independent risk factors predicting poor prognosis. Conclusion:Tumor budding is highly correlated with clinicopathological parameters which reflect the aggressiveness of pancreatic neuroendocrine tumor, it is also an important prognostic factor.

Objective:To investigate the predictive value of portal vein (PoV) blood circulating tumor cells (CTCs) count in patients with pancreatic cancer on the postoperative prognosis.Methods:The data of 58 patients receiving radical resection of pancreatic cancer and PoV CTCs detection at People's Hospital of Zhengzhou University from Aug 2018 to Jun 2020 were collected. According to the cut-off value of PoV CTCs>10/5 ml made by receiver operating characteristic curve (ROC), patients were divided into high CTCs group and low CTCs group and the differences in clinicopathological parameters and prognosis of the two groups were compared.Results:Postoperative progression-free survival rate of the low CTCs group was higher than that of the high CTCs group ( χ 2=12.97, P<0.001).Univariate COX regression analysis showed that tumor diameter >4 cm, lymph node invasion, TNM staging, CTCs>10/5 ml, postoperative CA199>37 U/m were risk factors for postoperative prognosis. Multivariate COX regression analysis demonstrated that TNM stage ( OR=2.782, P=0.024), CTCs count >10/5 ml ( OR=2.583, P=0.047), postoperative CA199>37 U/m ( OR=3.775, P=0.004) were the independent risk factors of prognosis. Conclusion:A higher PoV CTCs count was a risk factor for poor prognosis of patients with pancreatic cancer after radical resection.

Objective To evaluate the clinical application value of portal vein implantation pump for chemotherapy in patients with intrahepatic cholangiocarcinoma (ICC) after radical surgery.Methods The clinical data of 97 patients with ICC who underwent radical surgery in Henan People's Hospital from June 2012 to June 2016 were retrospectively analyzed.Results Among the 97 patients,14 patients received portal venous pump chemotherapy (portal group),33 patients received peripheral venous chemotherapy (peripheral group),and 50 patients did not receive postoperative chemotherapy (control group).There were no statistically significant differences in gender and age between the three groups.The results of survival analysis indicated that the disease-free survival (DFS) period and overall survival (OS) time in the portal group and the peripheral group were significantly better than that in control group (both P ＜ 0.05).In addition,despite the lack of statistical significance (P ＞ 0.05),for the control of intrahepatic metastasis,portal vein pump chemotherapy was better than that of systemic chemotherapy via peripheral vein,and almost all side effects of chemotherapy in the portal group were lower than those in the peripheral group.Conclusion Portal vein pump chemotherapy can improve the prognosis of intrahepatic bile duct patients,especially for the control of intrahepatic metastasis,and can reduce systemic side effects of chemotherapy.

Objective To investigate the clinical application value of fluorescence laparoscopy in radical resection of hepatocellular carcinoma (HCC).Methods Data of totally 113 patients with HCC in Henan Provincial People's Hospital between June 2016 to June 2018 were retrospectively analyzed.Among the 113 patients,46 patients underwent laparoscopic hepatectomy (LLR),and 67 patients underwent fluorescence guided laparoscopic hepatectomy (FLLR).Results No significant differences were observed between LLR group and FLLR group in terms of age,male proportion,liver function classification,surgical resection methods,and operation time (P＞0.05).The positive ratio of specimen surgical margin in LLR group was significantly higher than that in FLLR group,13.0％ vs.3.0％,and the difference was statistically significant (P＜0.05).In the FLLR group,22 patients received fluorescence guided anatomic hepatectomy with indocyanine green (ICG),10 with positive staining and 12 with negative staining,and fluorescence imaging was observed 2 minutes after ICG injection.There was no significant difference in operation time,hospitalization cost and length of stay between positive and negative staining (P＞ 0.05).Conclusion Fluorescence laparoscopy has certain advantages in hepatectomy,and can display the boundary of hepatocellular carcinoma in real time to ensure the safe margin of tumor resection.
