ABSTRACT

Objective To investigate the effect of time interval between diagnosis and surgical treatment on the prognosis of breast cancer.Methods A retrospective study that include a total of 252 female patients who underwent breast cancer diagnosis and treatment in the Second Affiliated Hospital of Xi'an Jiaotong University from April 2012 to August 2014 were included in the present study,the average age was (58.2 ± 10.8) years old,range from 31 to 67 years old.General demographic information and data of tumor were collected.Information on postoperative recurrence,metastasis,death,and disease-free survival status of breast cancer patients were followed up 5 years by outpatient follow-up or telephone follow-up.All participants were divided into four groups (<2 weeks,2-4 weeks,4-8 weeks,≥8 weeks) by the time interval between diagnosis and surgical treatment,including 26,118,78 and 30 cases,respectively.In addition,according to the diameter of breast cancer tumors,all participants were divided into three groups (<20 mm,20-40 mm,and ≥40 mm),including 99,124,and 29 cases,respectively.According to the results of pathological examination of the lymph nodes obtained during intraoperative dissection,the all participants were divided into three groups (lymph nodes without metastasis,1 to 3 metastasis,and ≥3 metastasis),including 66,124,and 62 cases,respectively.The Cox proportional regression risk models were used to assess the hazard ratio (HR) and its 95% confidence interval (CI) of time interval between diagnosis and surgical treatment with the prognosis of breast cancer,with adjustment for age,education levels and body mass index.Further,stratified analysis by tumor characteristics,including pathological type,histological grade,tumor diameter,lymph node metastasis,and receptor expression were also conducted to evaluated the above association.Kaplan-Meier survival curve was used to evaluate the effects of time interval between diagnosis and surgical treatment on the prognosis of breast cancer.Results The Kaplan-Meier survival curves for the five-year follow-up of total survival time between 4 different time intervals groups showed significantly different (P <0.001),and patients with a pre-treatment interval of <2 weeks had the longest survival time,while those with ≥8 weeks had the lowest survival time.With a one-week interval before treatment,the overall risk of death in breast cancer patients increased by 6% (HR =1.06,95% CI:1.01-1.1 l),and the risk of breast cancer death increased by 8% (HR =1.08,95% CI:1.02-1.14),the risk of distant metastasis of breast cancer cells increased by 10% (HR =1.10,95% CI:1.08-1.13).With the increase in breast cancer tumor diameter (<20 mm,20-40 mm,≥40 mm),the overall risk of death due to prolonged treatment interval increased gradually,with HR (95%CI) were 1.06 (1.03-1.09),1.08 (1.02-1.12) and 1.11 (1.05-1.17),respectively.With the increase of lymph node metastasis in breast cancer (no metastasis,metastasis at 1-3,≥ 3 metastasis),the total mortality risk caused by prolonged treatment time interval also showed an increasing trend,with HR (95%CI) were 1.04 (1.02-1.08),1.06 (1.04-1.08) and 1.08 (0.99-1.11),respectively.The same results were also shown in the effect of tumor diameter or distant lymph node metastasis on the association between treatment time interval and breast cancer survival and distant metastasis of breast cancer cells.Conclusion With the prolongation of the time interval between the diagnosis of the breast cancer and the surgical treatment of breast cancer patients,the risk of postoperative death is significantly increased,and the association is more pronounced in breast cancer patients with larger tumor volume or higher distant lymph node metastasis.

ABSTRACT

Objective To investigate the treatment strategy for the re-operation patients with gallbladder cancer revealed by pathological results after laparoscopic cholecystectomy .Methods The clinical data in 15 cases of gallbladder cancer found by pa-thology after laparoscopic cholecystectomy in the general surgery department of this hospital during 2009-2013 were retrospective-ly analyzed .Results The pathological results on 3-5 d after laparoscopic cholecystectomy in 15 cases showed gallbladder cancer , tumor located at the gallbladder fundus in 2 cases ,the gallbladder body in 2 cases and gallbladder neck in 9 cases;there were 1 case of severe atypical hyperplasia ,2 cases of high differentiation adenocarcinoma ,9 cases of middle differentiation adenocarcinoma and 3 cases of low differentiation adenocarcinoma ;there were 1 case of Tis ,8 cases of pT Ⅰa ,6 cases of pTⅠb ,and 15 cases of bile tube incisal edge were negative .All 15 cases received re-laparotomy and hepatic duodenal ligament lymph nodes resection on 6-11 d af-ter cholecystectomy ,There were 1 case in the stage 0 ,8 cases in the stage Ⅰa ,5 cases in the stage Ⅰb ,1 case in the stage Ⅲb by TNM classification .The postoperative follow up lasted for 28 -79 months ,the accumulative survival rate was 100% in 1 year , 100% in 2 year ,93% in 3 year ,93% in 5 year .One case of stage Ⅲb was found repeated metastasis obstructive jaundice ,received transcutaneous puncture bile tract drainage and died after 3 months;no postoperative incision implantation metastasis was found . Conclusion Gallbladder cancer found by pathological examination after laparoscopic cholecystectomy is generally in early stage . Therefore ,early conducting the additional hepatic duodenal ligament lymphadenectomy has relatively good prognosis .

ABSTRACT

Objective To investigate the effect of high intensity focused ultrasound(HIFU) on the immunity of patients with advanced primary liver cancer(PLC).Methods Forty cases of PLC admitted to our institution from Mar.2003 to Dec.2003 were included in this study.Patients were divided into 2 groups and received either HIFU or radio-frequency ablation(RFA) treatment randomly.CD3,CD4,CD8,CD4/CD8,NK,IL-2,TNF were chosen to assess the immune status before and after treatment.The results were compared statistically.(Results The) survival rate after HIFU was 80.0%,61.1%,42.9%,33.3% at 3 months,6 months,9 months and 1 year respectively,which was similar to that after RFA treatment.The changes of immunity parameters of CD3,CD4,CD8,CD4/CD8,NK,IL-2 and TNF were not significant after HIFU treatment.In addition,the differences of those parameters between HIFU group and RFA group were insignificant.Conclusion There are no detrimental effects on immunity in the early period after HIFU treatment.
