To preliminarily determine the appropriate dosage of carboplatin (CBP) at AUC of 5 mg.Ml(-1).min(-1) in the combination chemotherapy for Chinese senile patients with non-small cell lung cancer (NSCLC). Thirty-five Chinese senile patients with NSCLC in advanced stage (III/IV) were given 96 cycles of combination chemotherapy. Chemotherapy schedules included Taxol+CBP, Gemzar+CBP and NVB+CBP. The dose of CBP was at 5 mg.mL(-1).min(-1) of area under the concentration-time curve (AUC). Side effects and quality of life were observed before and after the chemotherapy. Myelosuppression was severe and commonly observed. Grade 3/4 of granulocytopenia was found in 47.9% (46/96) of the patients and grade 3/4 of thrombocytopenia was noted in 28.1% (27/96) of the subjects. However, other side effects were slight. The mean score of quality of life (QOL), according to the criteria of QOL for Chinese cancer patients had reduced 6.8. At 5 mg.mL(-1).min(-1) by AUC, the hematological toxicity of CBP was severe and it had some negative effects on the QOL. The administration of CBP at 5 mg.mL(-1).min(-1) by AUC may be too high for Chinese senile patients with non-small cell lung cancer.

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 observe the correlation between long term efficacy/safety and treatment cycles of rh-endostatin (endostar) combined with TP (paclitaxel plus cisplatin/carboplatin) or NP (navelbine plus cisplatin/carboplatin) regimens in patients with advanced non-small cell lung cancer (NSCLC).

METHODSTwenty-five patients with advanced NSCLC confirmed by histopathology and/or cytology were enrolled in this study. Twenty-one patients underwent endostar combined with NP regimen and other four patients underwent endostar combined with TP regimen (all repeated 21 days) treatment. The therapeutic effects, quality of life (QOL) and adverse effects were evaluated according to RECIST criteria, Karnofsky performance scores and WHO grading of adverse effects, respectively. Our intention was to make knowledge of the therapeutic effects, median time to progression, one-year survival rate, median overall survival and adverse reactions. The amount of circulating endothelial cells (CEC) in peripheral blood was measured by flow cytometry.

RESULTSAll the 25 patients were evaluable for efficacy and safety. They were comprised of 5 cases of PR, 14 cases of SD and 6 cases of PD. Of the 25 cases, RR was obtained in 5 cases (20.0%), CBR in 19 cases (76.0%), mTTP was 8 months and mOS was 19 months. Of the 14 patients with short treatment cycles (< 4), PR was obtained in 2 cases, SD in 6 cases and PD in 6 cases, RR was 14.3%. Of the 8 patients who obtained PR or SD, the median TTP was 6 months and median overall survival was 18 months. Of the 11 patients with long treatment cycles (≥ 4), PR was obtained in 3 cases, SD in 8 cases, RR was 27.3%, mTTP was 17 months and mOS was 26 months. After treatment, the amount of activated CECs was increased by (293 ± 12)/10(5) in patients with short treatment cycles, and decreased by (243 ± 181)/10(5) in patients with long treatment cycles. A positive correlation was found between the changes of activated CECs after therapy, time to progression (TTP) and treatment cycles (r = 0.970, P = 0.001; r = 0.829, P = 0.042, respectively). The quality of life (QOL) was improved in 12 cases (48.0%), stable in 10 cases (40.0%), and decreased in 3 cases (12.0%). Grade 3 and 4 toxicities were mainly related with chemotherapeutics, including neutropenia in 4 cases (16.0%), vomiting in 3 cases (12.0%) and arrhythmia in 1 case. No hypertension was observed. All the adverse reactions did not affect the following treatment, and there was no significant difference in incidence rate of grade 3 and 4 adverse events between the patients treated with long-term and short-term cycles.

CONCLUSIONSEndostar combined with TP or NP regimen chemotherapy is effective and safe in the treatment of advanced NSCLC, especially in patients with long term treatment cycles which can effectively prolong TTP and reach long term survival, but not increase adverse events. The QOL of patients can be improved or remain stable. The changes of CECs may be used as a useful maker in predicting the efficacy of the combination treatment.

OBJECTIVETo investigate the relationship between peak concentration (Cmax) of gemcitabine at fixed-dose-rate and its hematological toxicity profile in patients with advanced non-small-cell lung cancer (NSCLC).

METHODSTwenty-one patients received gemcitabine at a fixed dose rate (1200 mg/m2 over 120 min) with carboplatin. Plasma concentrations of gemcitabine were measured by ion-pair reversed-phase high-performance liquid chromatography.

RESULTSThe mean value of Cmax in 21 eligible patients was(4.95+/-2.42) microg *ml(-1). The main hematological toxicity was grade III-IV thrombocytopenia and neutropenia. The mean percentages of reduction of WBC, NEC, PLTC and Hb of 21 patients were (38.3+/-38.1)%, (31.3+/-73.6)%, (31.8+/-53.5)% and (12.0+/-12.2)%, respectively. The C(max)of gemcitabine and the percentage of reduction in WBC showed a significant correlation (r2=0.4575, P<0.05). A significant correlation (r2=0.5671, P<0.05) was also observed between the percentage of reduction of PLTC and Cmaxof gemcitabine.

CONCLUSIONThe results of relationship between Cmax and toxicity profile suggest that gemcitabine administration should be individualized in order to decrease the occurrence of ADR.

BACKGROUND AND OBJECTIVEThe platinum-based chemotherapy combined with 5-fluorouracil (5-FU) is most frequently used for nasopharyngeal carcinoma (NPC), but the efficacy has been maintained at 50%-60%. Docetaxel is an effective drug for head and neck tumors, its administration is simple, and the administration time is short. This study was to compare the short-term efficacy and toxicity between TC regimen (inductive chemotherapy with docetaxol plus carboplatin) and FC regimen (5-FU plus carboplatin) in local advanced NPC so as to provide a new chemotherapeutic regimen for NPC.

METHODSFifty-eight local advanced NPC patients without previous treatment in Sun Yat-sen University Cancer Center were randomly assigned to receive either TC or FC regimen inductive chemotherapy, followed by concurrent chemoradiotherapy with two cycles of carboplatin (AUC=6) plus radiotherapy of 60-78 Gy to the nasopharynx and 60-70 Gy to the neck. The short-term efficacy and adverse events were observed.

RESULTSMore chemotherapy cycles were finished in TC group than in FC group (3.31 vs. 2.83, P = 0.043). There was no significant difference in short-term efficacy and 1-year survival rate between the two groups (P > 0.05). More grades 3-4 neutropenia appeared in TC group than in FC group (72.4% vs. 37.9%, P < 0.05) , whereas less thrombocytopenia and emesis occurred in TC than in FC group (P = 0.013 and 0.018, respectively).

CONCLUSIONSThe short-term efficacy of TC regimen in local advanced NPC is similar to that of FC regimen with tolerable adverse events. But the long-term outcomes and toxicities need to be further investigated.

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.

OBJECTIVETo compare the efficacy, side effects and influence of two chemotherapy regimens, paclitaxel liposome combined with platinum and paclitaxel combined with platinum, on the survival rate in patients with cervical carcinoma receiving concurrent chemoradiotherapy.

METHODSOne hundred and sixty two cases with primary cervical carcinoma diagnosed and treated in the Jiangxi Maternal and Children Hospital between January 2008 and November 2009 were enrolled in this randomized controlled trial. Seventy one cases were included in the paclitaxel group and 91 in the paclitaxel liposome group. The chemotherapy doses were as followings: paclitaxel liposome and paclitaxel 135 mg/m(2); cisplatin 80 mg/m(2) or carboplatin AUC 4 - 6, repeated every 21 days for two or three times. Radical radiotherapy was given to both groups at the same time. The efficacy was evaluated by the tumor regression and the patients were followed-up for six months.

RESULTSThe overall response rates of paclitaxel group and paclitaxel liposome group were 90.1% and 89.0%, respectively (P > 0.05). The 1-year cumulative survival rate was 91.4% for the paclitaxel group and 89.2% for the paclitaxel liposom group (P > 0.05). The incidence rate of adverse effects such as rash, gastrointestinal toxicity, bone marrow suppression and muscle/joint pain in the paclitaxel liposome group was significantly lower than that in the paclitaxel group (P < 0.05), while there was no significant difference regarding the hair loss, liver damage, and peripheral neuritis (P > 0.05).

CONCLUSIONSPaclitaxel liposome plus platinum is a safe and effective therapeutic regimen for stage IIa-IV cervical carcinoma. However, the long-term efficacy of this regimen should be further observed.

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.

Antibiotics-associated pseudomembranous colitis is well documented and caused by abnormal overgrowth of toxin producing Clostridium difficile colonizing the large bowel of patients undergoing antibiotic therapy. Administration of chemotherapeutic agents is frequently complicated by diarrhea and enterocolitis. However, pseudomembranous colitis related to chemotherapeutic agent usage is very rare. We experienced a 67 old-years male patient diagnosed of non-small cell lung carcinoma who complained of watery diarrhea and abdominal pain after treated with paclitaxel and carboplatin. Sigmoidoscopic examination revealed diffusely scattered, whitish to yellowish pseudo-membrane with background edematous hyperemic mucosa from sigmoid colon to rectum. Histopathologic findings were consistent with pseudomembranous colitis as typical volcano-like exudate. The symptoms improved after stopping chemotherapy and treatment with metronidazole. In patients with persistent diarrhea and abdominal pain after receiving chemotherapy agents, although rare, pseudomembranous colitis should be considered as a differential diagnosis.

BACKGROUND: The aim of this study was to evaluate the response, survival, and toxicities of a less intensive combination of paclitaxel and carboplatin, which is used in advanced non-small cell lung cancer (NSCLC) patients older than 60 years of age including those with a poor performance status. METHODS: Thirty patients received 135 mg/m2 of paclitaxel on day 1, and carboplatin was administered to the patients on day 1 every 4 weeks over an area under the concentration-time curve of 6. RESULTS: The response rate was 40%, the median overall survival was 9.1 months (95% CI, 4.2 to 14 months), and the 1 year survival rate was 31%. The median progression-free survival was 7.7 months (95% CI, 3.1 to 12.2 months). In addition, the toxicities were generally mild and reversible. CONCLUSION: This study demonstrates that a less intensive combination of paclitaxel/carboplatin is active and well tolerated in advanced NSCLC patients who are older than 60 years including those with a poor PS 3~4.
