ABSTRACT
Objective:To analyze the surgical methods of operable breast cancer and analyze the follow-up results.Methods:A retrospective analysis of the clinical and pathological data of 636 operable breast cancer patients admitted to Zibo First Hospital from July 2008 to April 2018, including the clinical stage, pathological staging. Analyze of the proportion of four surgical methods, and through follow-up, analyze the treatment effect of different surgical methods.Results:All patients are female, aged 26-80 years, the clinical stage of 636 patients: Tis 18 cases, stage Ⅰ 143 cases, stage Ⅱ 354 cases, stage Ⅲ 114 cases, stage Ⅳ 7 cases. There are four types of surgery: ① breast conserving surgery + sentinel lymph node biopsy in 124 cases (19.50%); ② breast conserving surgery + axillary lymph node dissection in 39 cases (6.13%); ③ mastectomy + sentinel lymph node biopsy in 163 cases (25.63%); ④ modified radical surgery in 310 cases (48.74%). Sentinel lymph node biopsy in 427 cases (67.14%), success in 404 patients (94.61%); all patients with lymph node negative 384 cases (60.38%). Follow-up for 1 to 9 years, 11 cases of local recurrence after breast-conserving surgery, It accounted for 6.75% of breast-conserving surgery; 43 cases of local recurrence of chest wall after mastectomy, accounting for mastectomy 9.09%; 33 cases of recurrence and metastasis of axillary lymph nodes and supraclavicular lymph nodes, 4 cases of axillary recurrence after sentinel lymph node biopsy.Conclusions:The proportion of breast-conserving surgery in this group of patients was high and the local recurrence rate of breast-conserving surgery was less than that of mastectomy group; the proportion of simple modified radical surgery declined further; patients with axillary lymph node metastasis were less in the whole group. The choice of reasonable operation method is an important factor to improve the prognosis of breast cancer.
ABSTRACT
Objective To assess the impact of radiation on superior epigastric vessel pedicled transverse rectus abdominal myocutaneous (TRAM) for breast reconstruction.Methods Female breast cancer patients were divided into 4 groups:group A (immediate breast reconstruction + radiation therapy,123 cases),group B (immediate breast reconstruction,262 cases),group C (radiation therapy + delayed breast reconstruction,34 cases),group D (delayed breast reconstruction,53 cases) from June 2009 to June 2012 at Department of Breast Oncology,Tianjin Medical University.Patient demographics,operative details,radiation therapy details,postoperative complications,patient-centered evaluation of aesthetic and psychological outcomes were assessed.Results The average follow-up duration was 24.98 ± 6.99 months.2.5％ patients developed delayed wound healing postoperatively.Fat necrosis and flap contracture were seen in 7.0％ and 3.6％ of all patients,respectively.Irradiated patients had a significant statistical difference in cancer staging,involved lymph nodes,tissue invasion and neoadjuvant chemotherapy (P ＜ 0.05).No significant statistical differences were observed in post-operative early complications,but in advanced stage complications.There was no significantly statistical difference in breast aesthetic outcome before and after radiation therapy within four groups.Conclusions For breast reconstruction patients,those without postoperative radiotherapy were suggested immediate breast reconstruction,and those with postoperative radiotherapy were proposed to accomplish breast reconstruction after postoperative radiotherapy.
ABSTRACT
Objective To investigate the application effects of ultrasonic scalpel combined with bipolar coag-ulation tweezers on open thyroid surgery.Methods 80 cases of thyroidectomy patients were randomly selected.These patients were divided into two groups by random cluster sampling method,whch were the study group (n =40)and control group (n =40).The control group of patients were given ultracision ligature methods combined with traditional therapy,while the study group of patients were given ultrasonic scalpel combined with bipolar coagulation tweezers treatment.And then the surgical related indicators and complications of the two groups of patients were statistically an-alyzed.Results Compared with the control group of (90.5 ±3.6)min,(6.5 ±0.6)d,(40.5 ±2.0)mL,(50.3 ± 1.4)mL and (6.6 ±0.5)cm,the operative time and length of stay of the study group of patients[(58.5 ±5.4)min and (3.4 ±0.2)d]were significantly shorter (t =6.965,3.143,all P <0.05);the blood loss and postoperative drainage of (5.0 ±1.4)mL and (1.0 ±0.6)mL were significantly less (t =4.541,3.747,all P <0.05);the cut diameter of (3.8 ±0.3)cm was significantly shorter (t =3.365,P <0.05);the complication rate of 2.5% (1 /40) was significantly lower than the control group 10.0%(4 /40)(χ2 =9.35,P <0.05).Conclusion The application effects of ultrasonic scalpel combined with bipolar coagulation tweezers on open thyroid surgery are obvious.
ABSTRACT
There are a lot of feasibility studies, using sentinel lymph node biopsy SLNB instead of Alex lymph node dissection (ALND), having got a conseusus that SLNB is a safe and useful method in the treatment of breast cancer. But in clinical practice, there are much false negative rate (FNR) which need to be carefully dealt with for SLNB. In order to diminish the FNR, how many nodes should be the perfect number to lower the FNR? If positive detection was found in the SLN, should ALND always be needed? And when micro metastasis was found in the post operation HE staining? Does it need further treatment? We make a review to discuss those matters.
ABSTRACT
OBJECTIVE To study the effects of Panax quinquef olium 20S-protopanaxdiol saponins extracted from the leaves of panax qu inque-folium (PQDS) on the hemodynamics and cardial oxygen metabolism in dogs with acute myocardial infarction (AMI).METHODS The paramete rs of hemodynamics and cardial oxygen metabolism were determined by using the mo del of ligation of LAD in the anaesthetized open-chest dogs.RESULTS In dogs treated with PQDS (in a dosage of 10 and 20 mg*kg-1 iv infusion),the myocardial blood flow (MBF) was increased and coronary vascular re sistance (CVR) was decreased significantly.The heart rate (HR) was slowed.The ar terial blood pressure (ABP),left ventricular pressure (LVP),the maximum rise rat e of left ventricular pressure(+dp/dtmax),left ventricular work index (LVW I) and total periphery resistance(TPR) were reduced,whereas the stroke index(SI) and cardiac index (CI) were increased.In addition,the decreasing range of the m aximum decline rate of left ventricular pressure(-dp/dtmax) and the rising range of left ventricular end diastolic pressure (LVEDP) were reduced.Meanwhile the cardiac oxygen consumption,myocardial oxygen utilization rate and cardiac o xygen consumption index were also decreased.CONCLUSION PQDS had protective effects on acute myocardial ischemia including improving heart fu nction,decreasing cardiac oxygen consumption and increasing myocardial blood flo w,etc.
ABSTRACT
Hemodynamic effects of Laigechongji (LGCJ)were studied in anesthetized open-chest dogs. LGCJ(in doseof 8. 5 and 17.0g/kg,id. )decreased significantly SBP, DBP, MAP, HR, LVSP, +dp/dt max and TPVR, 30~45 mins after medication,and continued for about 90~ 150mins. However,they had no significant effects ondp/dt max,LVEDP,CO,CI,SV and SI. These results suggest that LGCJ may cause hypotension,and its hypotensive effects may be related to its bradycardiac,negative inotropic and vascular resistance reducing activities.
