ABSTRACT
Objective To explore the application of carbon nanoparticles for tracing sentinel node(SN) in early gastric cancer (EGC).Methods Forty-six patients with EGC conducted subserous injection of carbon nanoparticle solution 1.0 mL at 4-6 points around tumor during operation.SN was examined by adopting 3 different methods.The first stained lymph node was defined as the first SN(FSN),and the whole group lymph nodes were identified as the group SN(GSN) and all lymph nodes colored within 5 min were labeled as the all SN(ASN).The affirmative SN and other resected lymph nodes were performed the histopathological examination and comparison.Resnlts In all 46 cases,SN was successfully detected out with the detection rate of 100％;the number of SN,GSN and ASN were 1.04 ± 0.21,3.93-±-1.90 and 13.61 ± 4.36 respectively,the difference in SN number among 3 different methods had statistical significance(P＜0.05).The accuracy rates of FSN,GSN and ASN for judging perigastric lymph node metastasis status were 95.65％,100％ and 100％,respectively.Conclusion The carbon nanoparticles tracing SN in EGC has higher staining rate and higher accuracy for predicting lymph node metastasis;GSN has high accuracy,moreover has less trauma and is most suitable method for detecting SN.
ABSTRACT
Objective To explore the treatment methods for colorectal cancer patients combined with active tuberculosis. Methods The clinical data of 8 cases of colorectal cancer combined with active tuberculosis from September 2011 to January 2017 in the Affiliated Hospital of Southwest Medical University were analyzed retrospectively. Results All the patients received tumor radical resection after given intensive anti-tuberculotherapy for 2 to 3 weeks. From the second day after surgery, isonicotinyl hydrazide was done through intravenous infusion. When gastrointestinal function was restored, the preoperative anti-tuberculosis treatment was reused. After 2 mouths, consolidation therapy was done. There were 3 cases of complicating pneumonia and 1 case of complicating anastomotic fistula after surgery.Six courses of FOLFOX4 chemotherapy combined with anti-tuberculosis consolidation treatment were carried out for all the patients. No tuberculosis dissemination or death case occurred. Conclusions After given anti-tuberculotherapy for 2 to 3 weeks, the colorectal cancer patients combined with active tuberculosis could receive tumor radical resection. It is safe and feasible to carry out assisted chemotherapy for tumor during the consolidation anti-tuberculotherapy.
ABSTRACT
OBJECTIVE:To investigate the effects of Fluorouracil implants on intraperitoneal chemotherapy safety of advanced gastric cancer patients. METHODS:The information of 264 patients with advanced gastric cancer were analyzed retrospectively. All patients were given Fluorouracil implants 800 mg,scattered into the mesenteric and surgical area,dose of each implantation site less than 200 mg,the distance of implantation range from incision and anastomosis more than 3 cm. All patients were given second generation cephalosporin 30 min before operation,at 3rd h during operation,1-3 d after operation. The occurrence of complications and ADR during hospitalization were observed after operation. RESULTS:After operation,6 patients suffered from complications, with incidence of 2.28%,including 3 cases of gastrointestinal reaction,2 cases of anastomotic bleeding and 1 case of anastomotic leakage. Routine blood test and liver and kidney function were rechecked 3 d after operation,mainly thrombocytopenia and liver function injury,with the incidence of 2.65%. CONCLUSIONS:Fluorouracil implants can be used for intraperitoneal chemotherapy of advanced gastric cancer patients. However,attention should be paid to thrombocytopenia and liver function injury.
