To evaluate the efficacy and safety of drug-eluding beads transarterial chemoembolization (DEB-TACE) in treatment of unrecectable hepatocellular carcinoma (HCC).The clinical data of 42 consecutive HCC patients undergoing TACE were retrospectively analyzed, including 20 cases received conventional TACE (cTACE group) and 22 cases received TACE with epirubicine-loaded microspheres (CalliSpheres) (DEB-TACE group). MRI scans were performed 1 week before and 1, 3 and 6 months after initial therapy. The response to treatment, disease recurrence, complications and adverse effects were documented and compared between two groups.There were no significant differences in 1-month, 3-month and 6-month objective response rate (CR+PR) and disease control rate (CR+PR+SD), disease recurrence, complications and adverse effects of interventional therapy between cTACE group and DEB-TACE group. Additionally, there were no significant differences about locoregional biliary injuries, intrahepatic biloma, and newly detected intra- or extrahepatic HCC on MRI between cTACE group and DEB-TACE group.There were no statistically significant differences between cTACE group and DEB-TACE group with regard to the short-term response, disease recurrence, complications and side effects. Hepatic-locoregional complications may be more frequent in DEB-TACE group than those in cTACE group.

OBJECTIVETo explore the safety and efficacy of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in preventing chemotherapy-induced neutropenia in patients with breast cancer and non-small cell lung cancer (NSCLC), and to provide the basis for clinical application.

METHODSAccording to the principle of open-label, randomized, parallel-group controlled clinical trial, all patients were randomized by 1∶1∶1 into three groups to receive PEG-rhG-CSF 100 μg/kg, PEG-rhG-CSF 6 mg, or rhG-CSF 5 μg/kg, respectively. The patients with breast cancer received two chemotherapy cycles, and the NSCLC patients received 1-2 cycles of chemotherapy according to their condition. All patients were treated with the combination chemotherapy of TAC (docetaxel+ epirubicin+ cyclophosphamide) or TA (docetaxel+ epirubicin), or the chemotherapy of docetaxel combined with carboplatin, with a 21 day cycle.

RESULTSThe duration of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg and PEG-rhG-CSF 6 mg groups were similar with that in the rhG-CSF 5 μg/kg group (P>0.05 for all). The incidence rate of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group, and G-CSF 5 μg/kg group were 69.7%, 68.4%, and 69.5%, respectively, with a non-significant difference among the three groups (P=0.963). The incidence rate of febrile neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg/kg group were 6.1%, 6.4%, and 5.5%, respectively, showing no significant difference among them (P=0.935). The incidence rate of adverse events in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg / kg group were 6.7%, 4.1%, and 5.5%, respectively, showing a non-significant difference among them (P=0.581).

CONCLUSIONSIn patients with breast cancer and non-small cell lung cancer (NSCLC) undergoing TAC/TA chemotherapy, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF at 48 hours after chemotherapy show definite therapeutic effect with a low incidence of adverse events and mild adverse reactions. Compared with the continuous daily injection of rhG-CSF 5 μg/kg/d, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF has similar effect and is more advantageous in preventing chemotherapy-induced neutropenia.

OBJECTIVETo detect the expression of IGF1R and estrogen receptor, and to explore the relationship between their expression and the pathological complete response (pCR) rate of neoadjuvant chemotherapy (docetaxel plus epirubicin) in breast cancer patients.

METHODSWe selected 139 women with breast cancer who underwent neoadjuvant chemotherapy (docetaxel plus epirubicin), and detected the expression of IGF1R and estrogen receptor in the samples taken before chemotherapy by Immunohistochemistry. The association between their expression and pCR rate of neoadjuvant chemotherapy was analyzed.

RESULTSAmong the 139 cases, IGF1R was highly expressed in 45.3% (63/139) cases, and ER was positively expressed in 62.6% (87/139) cases. IGF1R was highly expressed in 54.0% (47/87) of the ER+ cases, significantly higher than that of ER- cases (30.8%, P<0.01). The overall pCR rate of all the 139 patients who received docetaxel plus epirubicin as neoadjuvant chemotherapy was 10.1% (14/139). The pCR rate was 19.2% (10/52) of the ER- patients and 4.6% (4/87) of the ER+ patients (P<0.05). The pCR rate was 10.5% (8/76) in the patients with low IGF1R expression and 9.5% (6/63) in the patients with high IGF1R expression (P>0.05). The patients with negative expression of ER and high expression of IGF1R showed the highest pCR rate (31.2%, P<0.01).

CONCLUSIONSBreast cancer patients with negative expression of ER and high expression of IGF1R are more sensitive to neoadjuvant chemotherapy of docetaxel plus epirubicin, and their pCR rate is significantly higher than that of other patients.

OBJECTIVEThe aim of this study was to analyze the efficacy and safety of paclitaxel liposomal and docetaxel for neoadjuvant chemotherapy of breast cancer.

METHODSWe retrospectively analyzed the clinical data of 188 operable patients with breast cancer who received neoadjuvant chemotherapy. According to the treatment regimens, they were divided into the group of paclitaxel liposome (86 patients) and group of docetaxel (102 patients) treatment. All the patients received a combination therapy with epirubicin and cyclophosphamide, i.e. neoadjuvant chemotherapy with three drugs, 21 days as a cycle, and a total of 6 cycles. Surgery was carried out three weeks after the end of chemotherapy, and the chemotherapy efficacy and adverse reaction of both groups were evaluated.

RESULTSPathological complete response (pCR) rate in the paclitaxel liposome group and docetaxel group was 10.5% and 9.8%, respectively, the objective response rate (ORR) was 80.2% and 79.4%, respectively, and the disease control rate (DCR) was 95.3% and 93.1%, respectively, showing a non-significant difference in therapy efficacy between the two groups (P > 0.05). Safety analysis indicated that all the occurrence rates of skin and nail toxic reaction, body fluid retention, oral mucositis, allergic reaction (such as facial blushing, chest distress, palpitation, dyspnea. etc.), and grade III-IV leukopenia and neutropenia in the paclitaxel liposome group were significantly lower than that of the docetaxel group (all P < 0.05).

CONCLUSIONSCompared with docetaxel, paclitaxel liposome has the same anti-tumor efficacy, but causes fewer and milder adverse reactions with a higher safety in the neoadjuvant chemotherapy for breast cancer.

OBJECTIVETo retrospectively investigate the incidence of severe neutropenia and elevation of transaminase during neoadjuvant chemotherapy using epirubicin, cyclophosphamide and fluorouracil in breast cancer patients.

METHODSFrom January 2011 to December 2012, 303 consecutive breast cancer patients with complete treatment data treated in our department were included in this analysis. All patients received neoadjuvant chemotherapy with equal dose of EPI (100 mg/m(2)) administered every 3 weeks for 4 cycles before surgery.

RESULTS200 patients (66.0%) experienced at least one episode of grade 3/4 neutropenia/leukopenia, among them 176 patients experienced their first episode after the first cycle. Febrile neutropenia (FN) occurred in 13 patients for 14 episodes. Elevation of transaminase occurred in a total of 46 patients (15.2%), among them, grade 2 or higher elevation occurred in 15 patients (5.0%). Three blood test plans were adopted to monitor the patients during chemotherapy: (1) Routine blood count repeated every week; (2) Routine blood count before and on day 10 of each chemotherapy episode; (3) Routine blood count before and on day 7, 10 and 14 of each chemotherapy episode. The number of patients whose chemotherapy was delayed due to 3/4 neutropenia/leucopenia in each blood test plan was 3 (5.0%), 7 (3.9%) and 2 (3.2%), respectively. The number of patients with febrile neutropenia (FN) in each blood test plan was 2 (3.3%), 8 (4.4%) and 3 (4.8%), respectively. No statistically significant difference in treatment delay or the incidence of FN was observed among different blood test plans. No statistically significant difference in the incidence of grade 3/4 neutropenia/leukopenia or grade 2 or higher transaminase elevation was observed among different 5-Fu regimens.

CONCLUSIONSDuring neoadjuvant chemotherapy using FE100 C, Fci E100 C or E100 C for breast cancer patients without routine prophylactic G-CSF, the incidence of grade 3/4 neutropenia/leukopenia is 66.0%. With the patient management plan we adopted, 4.3% of patients developed febrile neutropenia. Prophylactic medication may not be necessary for patients without evident liver dysfunction.

OBJECTIVETo explore the expression of breast cancer resistance protein (ABCG2), p-glycoprotein (P-gp) in residual breast cancer tissue after chemotherapy and their correlation with epithelial mesenchymal transition (EMT).

METHODSSeventy-six cases of breast cancer were collected. The expression of ABCG2, P-gp and EMT markers E-cadherin and vimentin in residual breast cancer tissue after chemotherapy was detected by immunohistochemistry (EnVision method). MCF7 cells were divided into three group:untreated control group, positive control (TGF-β1 induced) group and drug surviving cells (DSC) group (selected viable MCF7 cells after docetaxel and epirubicin treatment). The expression of EMT markers E-cadherin and vimentin was detected by immunofluorescence. The mRNA and protein expression of ABCG2, P-gp and EMT markers were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot, respectively.

RESULTSCompared with breast cancer tissue before chemotherapy, ABCG2, P-gp and vimentin protein were highly expressed in residual breast cancer tissue after chemotherapy. The expression of ABCG2 and P-gp correlated positively with vimentin protein (r1=0.97, P1=0.000; r2=0.83, P2=0.001) and negatively with E-cadherin protein (r3=-0.55, P3=0.010; r4=-0.43, P4=0.020) expression. RT-PCR results showed that ABCG2, P-gp and vimentin mRNA were highly expressed in residual breast cancer tissue after chemotherapy. The expression of ABCG2 and P-gp mRNA correlated positively with vimentin mRNA (r1=0.99, r2=0.96, P<0.05) but negatively with E-cadherin protein (r3=-0.99, r4=-0.98, P<0.05); Western blot showed that ABCG2, P-gp and vimentin protein were highly expressed in residual breast cancer tissue after chemotherapy. The expression of ABCG2 and P-gp protein correlated positively with vimentin protein (r1=0.98, r2=0.89, P<0.05) and negatively with E-cadherin protein (r3=-0.47, r4=-0.33, P<0.05).

CONCLUSIONSThe expression of resistance-associated proteins in the residual breast cancer tissue after chemotherapy is significantly correlated with EMT. The expression of EMT profile may be one of important mechanisms for multidrug resistance in breast cancer.

In order to assess the effect of long-term versus short-term intravesical chemotherapy in preventing the recurrence of patients with non-muscle-invasive bladder cancer, we searched several databases with words as mesh terms and free text words to find all eligible randomized clinical trials (RCTs) for the comparison of the two strategies of instillation durations. "Observed-Expected events research (O-E)" and "Variance (V)" for calculating hazard ratio (HR) were used in Revman 5.2 software recommended by Cochrane Collabration for data analysis. Sensitivity and subgroup analysis were selected to minish heterogeneity. GRADEpro 3.6 profile recommended by Cochrane Collabration was employed for quality assessment of analyses. Finally, 13 eligible RCTs with 4216 patients were included in this review and 16 comparisons from 13 trials were involved for analysis. The pooled analysis revealed no significant difference between long-term and short-term duration [HR=0.99, 95% CI (0.89, 1.11), P=0.89]. Within the subgroup analysis, patients benefited from long-term instillations with a start regimen of one immediate instillation [HR=0.83, 95% CI (0.69, 1.00), P=0.05]. But patients were not suitable to receive long-term instillations with epirubicin (EPI) [HR=1.01, 95% CI (0.91, 1.13), P=0.78]. The progression rate was not reduced after long-term instillations [HR=0.96, 95% CI (0.66, 1.39), P=0.82]. From our results, patients should not receive introvesical chemotherapy more than half a year. In contrast, patients with one immediate instillation are preferred to have a long-term duration at least one year. Long-term instillations can not reduce the progression rate.

OBJECTIVETo explore the feasibility of short-term neoadjuvant chemotherapy (NACT) in patients with advanced gastric cancer (AGC), and to compare clinical efficacy of short-term neoadjuvant chemotherapy with different ways.

METHODSClinical data of 310 AGC patients treated with one course of NACT using EOF regimen(epirubicin, oxaliplatin and fluorouracil plus calcium folinate) in our hospital from January 2008 to December 2011 were retrospectively analyzes. Efficacy was compared between regional arterial infusion chemotherapy and intravenously chemotherapy.

RESULTSAll the 310 AGC patients completed one course of NACT and none was interrupted by adverse events. Postoperative pathological remission rate was 33.9% (105/310) and 5 patients (1.6%) had complete pathological remission. The pathologic response rate in the regional arterial infusion chemotherapy group was higher than that in the intravenously chemotherapy group(42.4% vs. 23.6%, P = 0.001). Multivariate analysis revealed that chemotherapy method(HR=1.827, 95% CI:1.006-3.316, P = 0.048) was associated with significantly higher pathologic response.

CONCLUSIONSPathological response rate is quite low following short-term NACT. Regional arterial infusion chemotherapy with short-term NACT can improve the pathological response rate of advanced gastric cancer.

OBJECTIVEThe aim of this study was to analyze the clinical characteristics, treatment and prognosis of advanced urothelial carcinoma of the bladder (AUCB).

METHODSThe clinicopathological data of 117 patients with AUCB admitted in our hospital from 1998 to 2009 were reviewed. All patients received first-line chemotherapy. The survival rate was calculated by Kaplan-Meier analysis and log-rank test.

RESULTSThe median age of all patients was 56 years and the male-to-female ratio was 3.33:1. Their 6-, 12-, 24-, 36- and 60-month survival rates were 90.3%, 61.3%, 32.3%, 24.2% and 8.1%, respectively. In the first-line chemotherapy regimen, the effectiveness rate of gemcitabine + platinum drugs was 49.3% (37/75), the median progression-free survival(PFS) was 7.9 months and overall survival (OS) was 18.7 months. The effectiveness of cyclophosphamide + epirubicin + platinum drug regimen was 45.5% (10/22), Median PFS was 7.1 months and OS was 15.3 months. The effectiveness of paclitaxel + platinum drug regimen was 47.1% (8/17), median PFS was 6.5 months and OS was 13.7 months. Among them, the effectiveness rate of the gemcitabine + cisplatin regimen in 67 patients was 47.8%, the median PFS was 7.0 months and OS was 15.3 months. In the 13 patients who received paclitaxel + carboplatin regimen, the effectiveness rate was 53.8%, median PFS was 7.7 months and OS was 16.0 months. The major side effects were leucopenia and thrombocytopenia, mostly were tolerable, of grade I to II.

CONCLUSIONSIn advanced unresectable and metastatic urothelial carcinoma of the bladder, GC regimen is recognized as a standard first-line chemotherapy, with a higher effectiveness and tolerable side effects. Taxane and molecular targeted drugs may further improve the therapeutic effect of the treatment of advanced urothelial carcinomas of the bladder in the future.
