Objective: To evaluate the efficacy and survival outcomes of dose-dense (biweekly) carboplatin plus paclitaxel (PC) as neoadjuvant chemotherapy (NAC) in triple-negative breast cancer (TNBC), and to explore an optimal neoadjuvant chemotherapy regimen for TNBC. Methods: Patients diagnosed as TNBC(cT1-4N0-3M0) in Cancer Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College Between January 2008 and September 2018 who received dose-dense PC and standard 3-weekly PC as NAC were 1∶1 matched using propensity score matching (PSM) to compare the efficacy, safety and survival outcomes. Results: One hundred of TNBC patients were enrolled (50 patients were divided in dose-dense group, 50 patients in standard group). The objective response rate (ORR) of dose-dense group and standard group were both 90.0% (45/50). The grade 3-4 neutropenia in dose-dense group was less than that of standard group (32.7% vs. 68.0%, P=0.001), while the rate of ALT/AST elevation in dose-dense group was higher than that of standard group (57.1% vs. 32.0%, P=0.012). The pathological complete response (pCR) rates were 34.0% (17/50) in dose-dense group and 38.0% (19/50) in standard group, without statistically significance (P=0.677). The median follow-up time was 55 months (3-150 months). The 5-year recurrence-free survival (RFS) in dose-dense group and standard group were 83.5% and 75.2%, respectively the 5-year overall survival (OS) in dose-dense and standard group were 87.9% and 84.5% the difference were not statistically significant (P=0.322 and 0.647, respectively). Patients with residual disease (tumor size≥1 cm or lymph node positive) had poor prognosis, the 5-year RFS and OS were 59.3% and 68.5%, respectively. Conclusions: Dose-dense PC has similar efficacy with standard 3-weekly PC and has a good safety profile. Since dose-dense regimen can shorten the duration of therapy, it can be an alternative in TNBC.

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.

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.

OBJECTIVETo observe the clinical efficacy and safety of pemetrexed or gemcitabine combined with carboplatin as the first-line therapy in elderly patients with advanced non-small cell lung cancer (NSCLC).

METHODSSeventy patients aged 70 years or over with stage IIIb-IV NSCLC were equally and randomly divided into pemetrexed plus cisplatin group (PC) and gemcitabine plus carboplatin group (GC). Patients in the PC group received pemetrexed (PEM) 500 mg/m(2) on day 1, and carboplatin (CBP) AUC5 on day 1 for 21-day cycle. Patients in the GC group received gemcitabine 1000 mg/m(2) on days 1 and 8, CBP AUC5 on day 1 for a 21-day cycle.

RESULTSIn the PC and GC groups, CR 0 and 0, PR 10 and 8, response rates 28.6% and 22.9% were observed, respectively. There was no statistically significant difference between the two groups (χ(2) = 0.299, P = 0.584). The 1-year and 2-year survival rates of the PC and GC groups were 48.6% vs. 45.7% and 11.4% vs. 11.4%, respectively, with a median survival of 11.00 and 10.00 months, without a statistically significant difference between the two groups (χ(2) = 0.01, P = 0.919). Regarding toxicities, the incidences of neutropenia/thrombocytopenia, nausea and vomiting (grade III ∼ IV) in the GC group were significantly higher than those in the PC group (P < 0.05). According to the observer scale of lung cancer symptoms, the post-treatment scores improved in both the two groups, and with no significant difference between them (P > 0.05).

CONCLUSIONSPC and GC show similar efficacy for elderly NSCLC patients, however, the toxicities in PC patients are lower than those in GC patients. Thus, pemetrexed combined with carboplatin is an effective chemotherapeutic regimen for advanced NSCLC in elderly patients.

OBJECTIVETo evaluate the efficacy, safety and survival of combination of carboplatin plus paclitaxel as neoadjuvant chemotherapy (NACT) for patients with locally advanced triple-negative breast cancer (TNBC), and explore an optimal regimen for TNBC.

METHODSPatients with core needle biopsy confirmed pathological diagnosis of IIA ∼ IIIC invasive breast cancer, negative for estrogen and progesterone receptors and HER2 by immunohistochemistry, and with indication for NACT were eligible in this study. The biopsy tumor tissues were tested for CK5/6, CK14, EGFR and Ki67. The patients received paclitaxel 175 mg/m(2) on day 1, carboplatin at an area under the curve 5 mg×min/ml on day 2 of every 21 days. The clinical response was evaluated every 2 cycles according to Standard RECIST 1.0 criteria and surgery was done after four to six cycles. Pathological complete remission (pCR) was defined if absence of invasive tumor in the breast and axillary lymph nodes samples or residual carcinoma in situ only.

RESULTSOverall, thirty-one patients were enrolled from January 2008 to November 2010. The median age was 51 years and 83.9% of the patients were diagnosed as stage IIB to IIIC diseases. 30 Patients completed chemotherapy as planed while one patient changed regimen due to paclitaxel allergy. Twenty-eight patients could be evaluated for clinical efficacy, of which CR, PR, SD, PD were achieved in 4, 20, 3 and 1 women, respectively. The objective response rate was 85.7%. The expression rate of CK5/6, CK14 and EGFR were 88.9% (24/27), 59.3% (16/27) and 63% (17/27), respectively. Among 27 patients who received modified radical mastectomy or breast-conserving surgery, 11 patients obtained pCR, with a pCR rate of 40.7% (95%CI 22.2% - 59.3%). Five of six CK5/6- and CK14-positive patients achieved pCR. All the 31 patients could be evaluated for toxicity according to the NCI-CTC v3.0 criteria. The major toxicities were neutropenia (93.5%), vomiting (45.2%) and ALT/AST increase (32.3%), and grade 3-4 toxicities accounted for 74.2%, 3.2%, 0, respectively. Until December 2011, at a median follow-up of 28.9 months (range 5 - 47.9), eight patients developed recurrence including 5 patients died. Among 11 patients with pCR, one suffered from lung metastasis at 45 months after diagnosis and survived with tumor until now. The other ten were alive and disease free. The 3-year DFS and OS were 62% and 74.7%, respectively.

CONCLUSIONSAs a neoadjuvant treatment for triple-negative breast cancer, carboplatin plus paclitaxel regimen achieves notable higher objective response rate and pCR rate compared with the anthracycline plus paclitaxel regimen reported in the literature, and is well tolerable. It is an optimized regimen for TNBC.

OBJECTIVETriple-negative [estrogen receptor (ER)-/progesterone receptor (PR)-/HER2-] breast cancer (TNBC) accounts for ∼ 15% of overall breast cancer and associated with a poor prognosis. There is a short of standard adjuvant chemotherapy regimens for TNBC. A number of studies have shown that TNBC might be sensitive to cisplatin and carboplatin on the basis that dysfunction of BRCA1 and its pathway is associated with a specific DNA-repair defect, but data of adjuvant setting about this is limited.

METHODSFrom January 2010 to September 2011, 95 early triple-negative breast cancer patients confirmed by pathology were randomly assigned to receive TP (docetaxel 75 mg/m², carboplatin AUC = 5, day 1, 21 days a cycle for 6 cycles) or EC-T (epirubicin 90 mg/m², cyclophosphamide 600 mg/m², d1, 21 days a cycle for 4 cycles, followed by docetaxel 80 mg/m², d1, 21 days a cycle for 4 cycles) chemotherapy. Adjuvant radiation therapy was given selectively after chemotherapy. Here we report a preliminary safety analysis with the chi-square test.

RESULTSSeventy-six out of the 95 patients had completed the chemotherapy and could be assessed for the safety profiles of the regimens. Thirty-seven of them were in the EC-T group with a median age of 47 years, and 21 out of these 37 patients were premenopausal (56.8%). Another 39 patients came from the TP group with a median age of 46 years, and 22 out of these 39 patients were premenopausal (56.4%). All of the 37 patients in EC-T group completed the planned treatment whereas 2 patients of the 39 cases in TP group did not because of bone marrow suppression. During the treatments, 9 patients had dose adjustment in each group. Adverse events of grade 1/2 were common. Specific incidence of adverse events with grade 3/4 in each group was as follows: alopecia, 29.7% vs. 10.3% (P = 0.033), vomiting 21.6% vs. 7.7% (P = 0.085), leukopenia 54.1% vs.25.6% (P = 0.011) and neutropenia 51.4% vs. 35.9% (P = 0.174). Other grade 3/4 toxicities were rare. All the adverse events (except peripheral neuropathy and pigmentation) recovered within 1 month after the chemotherapy.

CONCLUSIONBoth EC-T and TP regimens as adjuvant chemotherapy are safe and tolerable for the treatment of triple-negative breast cancer patients, while the TP regimen has advantages with less grade III/IV alopecia and leukopenia.

OBJECTIVETo study the differences of objective response rate (ORR), side effects and survival among patients with limited-stage small cell lung cancer (LD-SCLC), who received concurrent chemoradiotherapy, sequential chemoradiotherapy or chemotherapy alone, and to analyze the influencing factors on their survival.

METHODSOne hundred and sixty-six patients diagnosed as LD-SCLC in Peking Union Medical College Hospital from January 2000 to December 2009 were included in this study. The differences of objective response rates, side effects and survival rates were analyzed by χ2 test. Kaplan-Meier test was used to calculate the overall survival (OS) and progress-free survival (PFS). Cox regression was used to detect the influencing factors on survival time of the patients.

RESULTSThe patients were divided into three groups: concurrent chemoradiotherapy (49 cases), sequential chemoradiotherapy (62 cases) and chemotherapy alone (55 cases). The chemotherapy was based on CE/EP regimen, with an average cycle of 5.2. Radiotherapy was of a common or 3-dimensional conformal technology, for regular segmentation irradiation with an average dose of 49.6 Gy. The total ORR was 73.4%, OS and PFS were 22.9 months and 10.8 months, 1, 3, 5-year survival rates were 82.7%, 31.8%, 18.6%, respectively. For the concurrent group, sequential group and chemotherapy alone group, the ORR was 89.4%, 67.2% and 66.0%, respectively. Compared the chemotherapy alone group and concurrent group with the sequential group, there were significant differences (P<0.05). For the concurrent group, sequential group and chemotherapy alone group, the median OS was 29.7 months, 22.6 months, and 19.5 months; the median PFS was 12.7 months, 10.8 months, and 9.8 months, respectively, with a non-significant difference between each two groups (P>0.05). For the concurrent group, sequential group and chemotherapy alone group, the 1-year survival rates were 91.1%, 86.3%, and 65.6%, the 3-year survival rates were 44.2%, 28.3% and 22.8%, and the 5-year survival rates were 24.2%, 21.4% and 11.1%, respectively, with significant differences among them (P<0.05). The major side effects were myelosuppression, gastrointestinal reactions, radiation pneumonia and radiation esophagitis. For the concurrent group, sequential group and chemotherapy alone group, the incidence of myelosuppression were 84.4%, 76.8% and 60.0%, respectively, with a significant difference (P=0.008) between the concurrent group and chemotherapy alone group. For the concurrent group and sequential group, the incidences of radiation pneumonia were 22.2% and 22.9%, with a non-significant difference (P=0.940). The incidences of radiation esophagitis were 47.2% and 16.7%, respectively, with a significant difference (P=0.002). Multivariate analysis showed that OS was significantly associated with gender (P=0.018) and ECOG score (P=0.009), and PFS was significantly associated with gender (P=0.050).

CONCLUSIONSFor LD-SCLC, concurrent chemoradiotherapy can significantly increase the objective response rate. Concurrent chemoradiotherapy and sequential chemoradiotherapy compared with chemotherapy alone can extend survival, and concurrent chemoradiotherapy is better, but the differences among the three regimens are not significant. Gender and ECOG score are important influencing factors of survival.

OBJECTIVETo evaluate the efficacy of nimotuzumab combined with palitaxel liposome and carboplatin (LP) regimen for treatment of advanced non-small cell lung cancer (NSCLC), and to observe the changes of tumor markers and toxicities in the treatment. METHODS Forty-one patients with advanced NSCLC were randomly divided into 2 groups: 21 patients in the observation group were treated with nimotuzumab (200 mg per week for 6 weeks), palitaxel liposome 160 mg/m2 and carboplatin (AUC = 6). 20 patients in the control group were given LP regimen. Each group completed two cycles of chemotherapy. The level of tumor markers (CEA, CYFR21-1 and NSE) and toxicities were checked at one week before and after the treatment. Thoracic CT examinations were taken before treatment and at the fourth week and eighth week after treatment.

RESULTSIn the observation group, there were 2 cases of CR, 7 cases of PR, 9 cases of SD and 3 cases of PD. The objective response rate (RR) was 42. 9% in the observation group. In the control group, there were 1 case of CR, 6 cases of PR, 8 cases of SD and 5 cases of PD, with a RR of 35.0% in this group. There was no significant difference in the RR between the two groups (P = 0.751). The time to progression (TIP) was 6. 9 months in the observation group and 5. 7 months in the control group, with a significant difference (P = 0.027). The levels of NSE decreased significantly in both groups and showed a significant difference (P = 0.039). The levels of CEA and CYFRA21 in both groups were decreased after treatment, but did not show a significant difference before and after treatment, respectively. Except 3 cases had I-II skin toxicities on the faces in the observation group, there was no significant difference in toxicities between the two groups.

CONCLUSIONNimotuzmab combined with LP regimen shows a synergistic effect, can increase the efficacy and prolong TFP in advanced NSCLC patients. The toxicities are mild and tolerable.

OBJECTIVETo evaluate the efficacy of short-term intermittent prophylactic use of a recombinant human thrombopoietin (rhTPO) in chemotherapy-induced severe thrombocytopenia in lung cancer patients.

METHODS24 advanced non-small cell lung cancer (NSCLC) patients who experienced severe thrombocytopenia in the last chemotherapy cycle received prophylactic rhTPO treatment in the next chemotherapy cycle (prophylactic treated cycle, PTC). rhTPO was given subcutaneously 300 U×kg(-1)×d(-1) on days 2, 4, 6, and 9 after the initiation of chemotherapy. Platelet count was monitored and compared with that in the previous treatment cycle (control cycle, CC).

RESULTSThe lowest platelet count in the prophylactic rhTPO cycle was significantly higher than that in control cycle [(56 ± 16) × 10(9)/L vs. (28 ± 13) × 10(9)/L, P < 0.001]. The duration of thrombocytopenia was also shortened by the prophylactic rhTPO [(8 ± 2) d vs. (12 ± 3) d, P < 0.001]. The area under curve (AUC) of platelet count (21 days) was significantly increased [(3517 ± 685) × 10(9)/L vs. (2063 ± 436) × 10(9)/L, P < 0.001]. The time to platelet nadir and peak was not affected.

CONCLUSIONProphylactic use of rhTPO can attenuate the severity and shorten the duration of chemotherapy-induced thrombocytopenia in lung cancer patients.
