The “No-touch” technique improves the survival of patients with advanced hepatocellular carcinomas treated by liver transplantation: A single-center prospective randomized controlled trial

Background: Liver transplantation(LT) is the best treatment for patients with hepatocellular carcinoma(HCC). However, the surgical technique needs to be improved. The present study aimed to evaluate the “no-touch” technique in LT. Methods: From January 2018 to December 2019, we performed a prospective randomized controlled trial on HCC patients who underwent LT. The patients were randomized into two groups: a no-touch technique LT group(NT group, n = 38) and a conventional LT technique group(CT ...     

Influence of surgical techniques on survival in patients with colorectal cancer

This review was undertaken in an attempt to accumulate and critically evaluate all evidence that suggests that special techniques may alter survival rates of patients undergoing surgery for large-bowel cancer. Data suggesting reduced survival with a distal margin of resection less than 5 cm in patients undergoing anterior resection were found to be inconsistent.En bloc removal of the primary tumor and an adhesed adjacent structure seemed important, for 30 to 60 per cent survival has been reported using this approach, and adhesions were found to contain malignant cells at the interface of the primary tumor and adjacent structure in 40 to 100 per cent of patients. No statistically significant differences in survival rates were found in studies comparing conservative segmental bowel resection with radical hemicolectomy. This was true for colonic as well as rectal resections; while patient morbidity was not markedly increased for radical colectomy, it was found to be much greater with radical rectal resections. No data to support the use of “no-touch techniques” could be uncovered. Data to support the use of techniques for control of intraluminal tumor cells were sparse; however, because these maneuvers cost the patient little in terms of added morbidity, they should be used. Important aspects of the techniques for large-bowel surgery need to be investigated by prospective controlled clinical trials.     

单发直径≤3 cm肝肿瘤No-touch射频消融治疗的安全性及近期疗效分析(附50例报告)

目的探讨No-touch射频消融术(radiofrequency ablation,RFA)治疗直径≤3 cm单发肝肿瘤的安全性和疗效。方法 2015年9月至2017年6月采用cooltip电极对直径小于3 cm单发肝肿瘤50例病人进行No-touch RFA治疗。其中,治疗原发性肝癌49例(初发31例、复发18例),转移性肝癌1例。肿瘤平均直径1.8 cm,治疗前、后检查肝功能、增强CT扫描、磁共振检查、超声造影以及细针肝穿刺活检。观察RFA治疗时间、次数和术后住院时间,RFA治疗后的并发症以及肿瘤完全毁损率,并随访病人的生存情况。结果 50例病人共行No-touch RFA治疗51次,其中1例病人1个月内连续治疗2次。每例平均为1.02次;每次治疗时间平均为8.2 min;术后平均住院时间为3.2 d。Notouch RFA治疗后1个月内复查CT或磁共振,单次治疗后的肿瘤完全毁损率为98.0%,甲胎蛋白(AFP)阳性的22例病人在No-touch RFA治疗后6~12个月内有14例转阴,5例明显下降。50例病人随访时间从2015年9月开始至2017年6月止,其总体生存率为100%,术后总体无瘤生存率为90.0%(45/50)。结论 No-touch RFA对直径小于3 cm的单发肝肿瘤的治疗是一种微创、安全有效的方法。     

Circulating tumour cells during laparoscopic and open surgery for primary colonic cancer in portal and peripheral blood

Background

The objective of this study was to detect and quantify circulating tumour cells (CTC) in peripheral and portal blood of patients who had open or laparoscopic surgery for primary colonic cancer.

Methods

Patients in the laparoscopic-group were operated on in a medial to lateral approach (“vessels first”), in the open-group a lateral to medial approach was applied. The enumeration of CTC was performed with the CellSearch System. Intra-operative samples were taken paired-wise (from peripheral and portal circulation) directly after entering the abdominal cavity (T1), after mobilisation of the tumour baring segment (T2), and after tumour resection (T3). Ploidy of both the CTC and tissue of the primary tumour was determined for chromosome 1, 7, 8 and 17.

Results

Thirty-one patients were included; 18 patients had open surgery, 13 patients were operated on laparoscopically. The percentage of samples with CTC at T1 was 7% in peripheral blood and 54% in portal blood (p = 0.002). At T2, 4% and 31% respectively (p = 0.031). And at T3, 4% and 26% respectively (p = 0.125). The cumulative percentage of samples with CTC was significantly higher during open surgery as compared to the laparoscopic approach. Both the CTC and tissue of the primary tumour were diploid for chromosome 1, 7, 8 and 17.

Conclusion

The detection rate and quantity of CTC is significantly increased intra-operatively and is significantly higher in portal blood compared to peripheral blood. Significantly less CTC were detected during laparoscopic surgery probably as result of the medial to lateral approach.
