ABSTRACT
Objective To analyze the efficacy and safety of trastuzumab (H) and pertuzumab (P) combined with different chemotherapy regiments in neoadjuvant therapy for HER2-positive breast cancer. Methods We retrospectively analyzed the clinical data of the patients with HER2-positive breast cancer who received HP combined with chemotherapy as neoadjuvant therapy and completed surgery. The primary endpoint was total pathologic complete response (tpCR) (ypT0/isypN0), the secondary endpoints were breast pathologic complete response(bpCR) (ypT0/is) and axillary pathologic complete response (apCR) (ypN0), and the factors influencing pCR were analyzed. Results A total of 63 patients were included, of whom 23 were treated with TCbHP, 27 were treated with THP regimen, and 13 were treated with AC-THP. The overall tpCR rate was 65.1%, of which TCbHP was 73.9%, THP was 55.6%, and AC-THP was 69.2%. The tpCR rate of HR-negative patients was 79.2%, higher than that of HR-positive 56.4%. The overall bpCR rate was 69.8%, and apCR rate was 81.0%. Univariate analysis showed that HER2 status was a related factor affecting tpCR (P=0.023). The total effective rate by MRI was 87.3%. The level 3 and 4 toxicity of the TCbHP regimen was slightly higher than those of the THP and the AC-THP regimens. Conclusion HP combined with chemotherapy have achieved relatively high pCR. HER2 status is a related factor that affects tpCR. The adverse reactions are controllable.

ABSTRACT
Objective To investigate the effect of oral nutritional supplementation on the nutritional status and quality of life in patients with gastric cancer after operation.Methods In this prospective,single blind,randomized,controlled clinical study,25 postoperative patients with gastric cancer received neoadjuvant chemotherapy in outpatient clinic were enrolled.All patients received dietary guidance.In the intervention group,in addition to standard diet,oral nutritional supplements with 2 090 kJ/d of Intacted Protein Enteral Nutrition Powder were added,which lasted 90 days.The changes of body mass,body mass index(BMI),hemoglobin,prealbumin,albumin,gastrointestinal function score,and life quality score 30,60,and 90 days after discharge were recorded.Patients on standard diets were used as the control group.Results In the intervention group,the body mass increased by(0.66 ±1.47)kg 60 d after discharge and(-0.90±1.82)kg on 90 d after discharge,which were [60 d:(-5.13±1.79)kg,90 d:(-9.56±2.44)kg] in the control group,and the difference was statistically significant(P=0.027,P=0.015).The BMI of intervention group increased by(0.20 ±0.55)kg/m2 on 60 d and(-0.32±0.55)kg/m2 on 90 d after discharge,which were(-2.06±0.67)kg/m2 on 60d and(-3.21± 0.73)kg/m2 on 90 d in the control group(P=0.014,P=0.003).There was no significant difference in terms of serum albumin,prealbumin and other laboratory indicators.Intestinal functional status and quality of life also showed no significant difference between these two groups.ConclusionOral nutrition supplementation can reduce the body mass loss and improve the nutritional status in patients with gastric cancer during chemotherapy after operation.
ABSTRACT
Objective To investigate the clinicopathological features and prognostic factors in patients with low grade glioma. Methods Eighty- seven patients with low grade glioma confirmed by cytological examination were retrospectively analyzed. Results Among 87 patients, male accounted for 62.1%(54/87), and the average age was 36.2 years. The average followed- up time was 51.4 months (3-135 months), and 5 cases were lost in follow-up. The follow- up rate was 94.3% (82/87). The 3- year survival rate was 84.1%, and the 5- year survival rate was 66.7%. The 3- year survival rate was related to clinical symptoms, maximum diameter of tumor and the extent of resection (P<0.01 or<0.05);and the 5- year survival rate was related to years, Karnofsky score, clinical symptoms, maximum diameter of tumor, the pathology classification and extent of resection (P<0.05 or<0.01). Conclusions Low grade glioma is more common in male patients and patients under the age of 40 years. Age below 40 years, Karnofsky score ≥ 70 scores, only epilepsy symptom, tumor diameter below 6.0 cm, oligodendrogliomas, complete resection or subtotal resection are positive prognostic factors. Postoperative radiotherapy can reduce the rate of tumor progression.
ABSTRACT
Objective@#To assess the efficiency and safety of low-dose decitabine in patients with lower-risk myelodysplastic syndrome (MDS) to couple with the clinical significance of MDS-related gene mutations.@*Methods@#This study was done in 4 institutions in Zhejiang Province. A total of 62 newly diagnosed patients with lower-risk MDS were assigned to two groups of decitabine (12 mg·m-2·d-1 for 5 consecutive days) and best supportive care (BSC) . Their bone marrow samples were subject to examinations of MDS-related 15 gene mutations. The primary endpoints were the proportion of patients who achieved overall response (ORR) after at least two cycles and progression-free survival (PFS) , and their relevances to the gene mutations.@*Results@#Of 62 enrolled patients, and 51 cases were included in the final analysis. 16 of 24 patients (66.7%) in decitabine group achieved ORR versus 8 of 27 (29.6%) in BSC group (χ2=6.996, P=0.008) ; PFS prolongation of decitabine versus BSC was statistically significant (not reached vs 13.7 months, P=0.037) . Among 51 patients, at least one gene mutation was identified in 20 patients (39.2%) , including 4 single SF3B1 mutation. PFS in cases with gene mutations (not including single SF3B1 mutation) was significantly shorter than of no gene mutation (9.2 months vs 18.5 months, P=0.008) , but not for ORR (37.5% vs 58.1%, P=0.181) . Among 16 patients with mutated genes, ORR in decitabine and BSC groups were 75% (6/8) and 0 (0/8) , respectively. The most adverse events in decitabine group were grade 3 to 4 neutropenia (45.8%) and grade 3 to 4 infections (33.3%) .@*Conclusion@#This preliminary study showed that low-dose decitabine produced promising results with an acceptable safety in lower-risk MDS patients, especially for those with mutated genes. Further study targeting poor prognostic lower-risk MDS patients should be warranted.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between cytogenetic markers with World Health Organization (WHO) classification, disease progress and prognosis in cases with primary myelodysplastic syndromes (MDS).</p><p><b>METHODS</b>298 patients with de novo MDS from the first affiliated hospital of medical school, Zhejiang University were enrolled in the retrospective analysis of WHO classification, karyotype, and prognosis. Follow-up study was also conducted.</p><p><b>RESULTS</b>The WHO classifications at first diagnosis were as follows: refractory cytopenia with unilineage dysplasia (RCUD), 18 cases; refractory anemia with ring sideroblasts (RARS), 8 cases; refractory cytopenia with multiline dysplasia (RCMD), 104 cases; refractory anemia with excess blasts-1, 76 cases; refractory anemia with excess blasts-2, 85 cases; MDS unclassified (MDS-U), 5 cases involved; and single del (5q), 2 cases. 39.6% of MDS patients carried karyotypic abnormalities. Among them, the frequency of numerical abnormalities, structural abnormalities and the existence of composite abnormalities were 45, 31, and 42, respectively. The composite abnormalities were unbalanced translocations and complex chromosomal abnormalities. The incidence of both karyotypic abnormalities and complex chromosomal abnormalities in RAEB group was higher than that in non-RAEB group (P<0. 05). An analysis based on IPSS-R Scoring System showed that advanced risk stratification (except the low-risk group) gradually enhanced the incidence of karyotypic abnormalities (P<0.05). In addition, the probability of evolution to leukemia increased with the higher IPSS-R score (P<0.05). In RAEB group, the cases with +8 chromosome, accounting for 19.5% of karyotypic abnormalities, had worse prognosis than those with normal chromosomes.</p><p><b>CONCLUSION</b>Karyotype was identified with an independent risk factor in MDS patients. Therefore, the information on cytogenetic analysis was critical for diagnosis, prognosis and individual treatment. MDS patients presenting+8 chromosome, an intermediate risk factor, were associated with a poorer outcome compared to cases with normal chromosomes in RAEB group.</p>

<p><b>OBJECTIVE</b>To explore the incidence of chromosome 1 abnormality in myelodysplastic syndrome（MDS）to couple its association with clinical presentation and prognosis.</p><p><b>METHODS</b>R- band karyotype analyses were performed in 672 cases of MDS between 2010 and 2013. Clinical data of those with abnormal chromosome l were collected and then analyzed factors affecting the prognosis.</p><p><b>RESULTS</b>Of 672 cases of patients with MDS, chromosome 1 aberration［der（1）, dup（1）, －1 were most frequent］ were found in 41（6.1%）cases. 1q trisomy was found in 18/41（43.9%）cases, and the most common patterns were duplication of the long arm as well as unbalanced translocation with other chromosomes. Of 41 patients with chromosomal 1 abnormality, 32 cases were accompanied with other chromosomal aberration, usually involving 3 or more abnormal chromosomal karyotypes, e.g., chromosome 8, 7 abnormalities. According to IPSS-R scoring system, 19 patients were diagnosed with very high risk, 10 patients high risk, 10 patients intermediate risk and 2 patients low risk MDS. 9 patients transformed into acute leukemia with median transforming time of 7.18（0.56-54.28）months. Median survival of 36 cases after 2010 was 17.48（95% CI 14.38-20.58）months. There were significant differences on median survival between RAEB and non-RAEB groups（χ²=10.398, P=0.001）, and between with more than 3 chromosome abnormalities and with less than 3 groups（χ²=3.939, P=0.047）. RAEB was identified as an independent risk factor for the prognosis of MDS with chromosome 1 abnormality.</p><p><b>CONCLUSION</b>Chromosome 1 aberration was not rare in MDS. 1q trisomy was the most common abnormal karyotype in China, which often accompanied with other chromosomal abnormalities. The prognosis of MDS patients with chromosome 1 abnormality was poor, especially worse in those diagnosed with RAEB-1, RAEB-2 and with more than 3 chromosome abnormality. For patients whose percentage of bone marrow blasts less than 5%, the prognosis of patients with 1q trisomy was better than those without 1q trisomy. RAEB was identified as an independent risk factor for the prognosis of MDS with chromosome 1 abnormality.</p>

Objective To investigate the feasibility,safety and efficacy of laparoscopic and endoscopic cooperative surgery (LECS) for elderly patients with gastric gastrointestinal stromal tumor (GIST).Methods 54 cases with GIST aged 65 years and over in Department of Gastrointestinal Surgery in Beijing Hospital from Dec.2008 to Dec.2012 were selected.31 cases underwent LECS and 23 cases underwent open surgery.Clinical data including operation time,intraoperative blood loss,complications,tumor size,length of incision,postoperative gastrointestinal function recovery time,postoperative in hospitalization and follow up data were retrospectively analyzed in patients.Results There were 17 males and 14 females in the LECS group,and the mean age was (72.8±5.9)years.29 patients underwent laparoscopic-assisted partial gastrectomy,and 2 cases underwent laparoscopicassisted endoscopic dissection in LECS group.All operations were successful with no conversion to open surgery and death.There were 13 males and 10 females in the open surgery group,and the mean age was(73.3±6.1)years.The mean operation time was longer in LECS group than in open surgery group [(120.6±32.8) min vs.(86.3±33.5) min].The mean intraoperative blood loss,mean tumor size,mean length of incision,mean time of gastrointestinal function recovery,mean postoperative hospitalization were less or smaller in LECS group than in open surgery group [(40±23.4) ml vs.(130±65.6) ml,(2.3±1.2)cm vs.(3.6 ±1.8)cm,(3.6±1.1) cm vs.(14.4±3.5) cm,(47.7± 10.4)h vs.(61.4±11.9)h,(5.1±2.3)d vs.(7.2±2.5)d,respectively,t=3.192,1.831,5.212,2.014,3.519,P=0.002,0.012,0.000,0.015,0.001].According postoperative tumor risk assessment,13 cases were at very low risk,15 cases at low risk and 3 cases at middle risk in LECS group; 4 cases were at very low risk,14 cases at low risk and 5 cases at middle risk in open surgery group.The risk degree was lower in LECS group than in open surgery group (x2 =5.63,P=0.017).During a follow-up of 5 53 months,death without GIST was found in 5 patients in LECS group and 4 cases in open surgery group.Hepatic metastasis was found in 1 case in open surgery group.Conclusions LECS is a safe and feasibility alternative approach for elderly patients with gastric GISTs.It has more minimal invasion,fast recovery and satisfaction with short term outcomes as compared with conventional open surgery.
ABSTRACT
Objective To study the nutritional evaluation and clinical effects of perioperative enteral nutrition (EN) versus parenteral nutrition support (PN) in elderly patients undergoing gastrectomy for gastric carcinoma.The safety,feasibility and superiority were also compared between EN and PN.Methods Totally 50 cases (aged 65 years and over) undergoing gastrectomy for gastric carcinoma in Department of Gastrointestinal Surgery of Beijing Hospital were recruited and divided randomly into two groups of EN and PN (25 cases for each).NRS2002 nutritional assessment scoring system was used to evaluate the patients.The patients in EN group were given Rui Su at 2 d before surgery,then Wei wo,Bai pu li and Rui su were sequentially given from 12 h after the surgery.The patients in PN group were received total parenteral nutrition (TPN) via central venous for 7 days.Results The average absolute lymphocytes[(1.22±0.23) ×109/L and (1.31±0.27) ×109/L vs.(1.02±0.21) × 109/ L and (1.14 ± 0.23 × 10)9/L],pre-albumin[(151.442± 48.15) mg/ L and (167.38± 46.23) mg/ L vs.(115.22 ± 47.34) mg/L and (131.27 ± 43.58) mg/L] and transferring [(1.71±0.33)g /L and (1.83±0.31)g/L vs.(1.50±0.32)g/L and (1.65±0.32)g/L,all P＜0.05] levels after surgery of 3 d and 7 d in EN group were higher than those of PN group (P＜0.05).The CRP levels at 3 d and 7 d after surgery were increased in PN group compared with EN group [(63.71±35.26)mg/L and (41.58 ± 22.55)mg/L vs.(54.26±29.13)mg/L and (18.12 ±14.35)mg/L,P＜0.05].The blood sugar and insulin levels of EN group at 3 d and 7 d after surgery were (5.93±1.12) mmol/L and (5.61± 1.03)mmol/L,(6.72±5.14) U/L and (6.21±2.63) U/L,which were decreased compared to PN group (8.31 ± 2.62) mmol/L and (8.85 ± 2.92) mmol/L,(12.81±7.26) U/L and (15.21±8.24) U/L (P＜0.05).ALT in the PN group was (38.43±18.37) U/L at 7 d after surgery,higher than EN group (23.91± 14.82) U/L(P＜0.05).The perioperative average costs of EN group was (2714.5± 1391.7) yuan,lower than PN group (5041.6± 3007.7) yuan (P＜0.05).For the patients complicated with delayed gastric emptying after surgery,nutrition cost reduction was more evident.There were no significant difference between the two groups of patients in the liver and kidney function changes and postoperative complications.Conclusions It is safe and feasible for elderly gastric cancer patients with perioperative EN sequential therapy in view of its reduced stress response of surgical trauma and insulin resistance,improvement of hyperglycemia,reduction of medical costs compared with PN for elderly gastric cancer patients.
ABSTRACT
Objective To evaluate the effects of a carbohydrate-electrolyte solution on serum glucose, pancreas islet function and inflammatory response in elderly patients after abdominal operation.Methods It was a prospective, randomized, double-blinded and controlled trial. Totally 40 elderly patients after abdominal operation who met the defined criteria were enrolled. The subjects in study group were administered with 1000 ml carbohydrate-electrolyte solution intravenously in consecutive three days since 1st or 2nd postoperative day. Control group was administered with 1000 ml of 10% glucose on the same method. The changes of serum glucose, insulin, C-peptide and inflammatory response cytokine (IL-6, TNF-α, CRP) were detected before and after injection.Systemic inflammatory response syndrome (SIRS) was observed.Results All the 40 patients completed the study according to the study protocol. The incremental rate of serum glucose was significantly lower in study group than in control group on the 2nd and 3rd day after administration [(4.40±2.58) mmol/L vs. (14.97±3.44) mmol/L, t=2.984, P=0.008; (2.70± 1.55) mmol/L vs. (8.11± 2.60) mmol/L, t= 5.659, P= 0.000]. The changes of insulin and C-peptide of two group were similar before and after operation. The levels of IL-6 and TNF-α were significantly lower in study group than in control group on the 3rd day after administration[IL-6: (21.76±10.40) ng/Lvs. (50.17±35.24) ng/L, t=-2.447, P=0.034; TNF-α:(23.92±14.89) ng/L vs. (51.48±42.81) ng/L, t=-2.268, P=0.043]. In study group, 6 cases experienced SIRS and 4 cases had infective complications, but in control group the numbers were 8 and 6 respectively.Conclusions Appropriate application of carbohydrate-electrolyte solution intravenously has relatively mild effects on serum glucose and inflammatory response cytokine in elderly patients after abdominal operation, it decreases incidence of SIRS and maybe decrease infective complications.
ABSTRACT
Objective To investigate the clinical value of transanal endoscopic microsurgery (TEM) for the treatment of elderly patients with colorectal adenoma.Methods Totally 21 patients with colorectal villous adenoma underwent TEM from Dec.2007 to Sep.2010.The distance of adenoma from the anal verge was 4-20 cm (average 8.9 cm) and tumor size was 1.1-3.5 cm (average 1.9 cm).There were 12 cases with tubular adenoma and 9 cases with villous adenoma according to pre-operative diagnosis by colonoscopy and endoanal ultrasonography (EUS).Appropriate position and posture were dictated by the location of the tumor under general anesthesia.A special rectoscopy was inserted into the anus with CO2 insufflation to keep the rectum open.Under the stereoscopy and lapaoscopy-type instruments,the tumor was completely resected (submucosal or full-thickness excision) using a 5 mm ultrasonic dissector.The operative wound was closed with intra-lumen continuous sutures.Results The tumor was completely removed with negative resection margins in all the 21 patients (submucosal excision in 12 cases and full-thickness excision in 9 cases).The operating time was 40-100 min (average 76 min) and the intraoperative blood loss was 10-80 ml (average 50 ml).The post-operative stay was 2-10 d (average 4.5 d).The postoperative pathological stages were pT0 in 16 cases and pTia in 5 cases.The postoperative pathological diagnosis were tubular adenoma in 12 cases,villous adenoma in 9 cases,low-grade intraepithelial neoplasia (IN) in 5 cases and high-grade IN in 5 cases.Follow-up checkups in the 20 patients for 2-20 months (average 11 months) revealed no local recurrence.Conclusions TEM is safe and effective with little complication for the treatment of elderly patients with colorectal adenoma.Pre-operative EUS is very important for TEM.
ABSTRACT
Objective To evaluate the effects of carbohydrate-electrolyte solution(CES)on serum glucose,pancreas islet function,and safety in elderly patients after abdominal operation.Methods In this prospective,double-blinded,randomized,and controlled study,40 elderly patients who met the defined criteria were enrolled.Subjects in CES group were intravenously administered with 1 000 ml CES for consecutive three days beginning from the 1st and 2nd post-operative day,while subjects in the control group were administered with 10% glucose of the same volume under the same arrangement.The changes of serum glucose,insulin and insulin C-peptide,as well as lactic acid and uric acid and uric acid were determined before and after injection.Adverse events were recorded.Results All patients completed the study.The increase rate of serum glucose was significantly lower on the 2nd and 3rd day after injection in CES group than in control group(P=0.008,P:0.001).Blood insulin and insulin C-peptide levels showed increasing trends in both two groups,but were not significantly different between two groups(P=0.612,P=0.213).In the CES group,6 patients experienced systemic inflammatory response syndrome and 4 patients had infective complications after surgeries ;on the contrary,these two numerals were 8 and 6 in the control group(P=0.639,P=0.606).No increase in serum lactic acid or uric acid was detected.Conclusion Appropriate application of CES has minimal effect on the blood gluocse and pancreas islet function in elderly patients after abdominal surgery and may be helpful to improve clinical outcomes.
ABSTRACT
Objective To evaluate the color Doppler flow imaging (CDFI) findings in predicting possible difficulties of laparoscopic cholecystectomy (LC). Methods A total of 99 patients with acute cholecystitis received CDFI examination, and were divided into easy LC group (n=67) and difficult LC group (n=32) according to the indexes including the volume of gallbladder, the thickness of gallbladder wall, the condition of arterial flow in the gallbladder wall, the condition of gallbladder cavity and fossa, and of the intra-and extra-hepatic bile duct. After LC, all the patients were redivided into easy LC group and difficult LC group according to a difficulty scoring system of LC. The relationship among imaging results, operation difficulties and operation findings was investigated. Results According to the final score of difficulty scoring system of LC, the number of patients in easy LC group and difficult group was 61 and 38, respectively. Compared with easy LC group, patients in difficult LC group had bigger gallbladder volume [(39.5±13.2)am3 vs(32.6±10.4)cm3], thicker gallbladder wall [(10.1±4.0)mm vs(3.8±0.9)mm], more stone incarceration in the neck of gallbladder, abundant color blood flow signal of the gallbladder wall and more severe adhesion of gallbladder to the adjacent tissues, with statistical difference between the 2 groups (t=-2.820,-12.318,-3.952,x2=33.548,19.461,P<0.05). Using gallbladder volume, the thickness of gallbladder wall, infarction of stones in the neck of gallbladder and adhesion of gallbladder to the adjacent tissues as prediction indexes, the accuracy of CDFI in predicting the possible difficulties of LC was 94% (93/99). Conclusion Preoperative CDFI is helpful in predicting difficulties of LC for acute cholecystitis.
ABSTRACT
Objective To discuss the clinical character,mechanism and prevention of cerebral-cardiac syn-drome(CCS) during acute stroke. Methods 189 patients with CCS caused by acute stroke were Analysed retrospec-tively. Results The incidence rate of CCS following stroke was 55.0%. 84.6% patients with CCS occur in the first 72h. The dead rate of acute stroke with CCS was 26.9%, significartly higher than that of without CCS( P<0.01 ). Conclusion CCS is associated with type and pathologic site of acute stroke. The prognosis of acute stroke with CCS was worse than that without CCS.
