Docetaxel and cisplatin combination chemotherapy in anthracyclines-resistant advanced breast cancer

Objective： To observe the effect and toxicity of docetaxel with cisplatin in anthracyclines-resistant advanced breast cancer. Methods： Forty-five female patients received docetaxel 60 mg/m^2 on dl and cisplatin 30 mg/m^2 on d1-d3 of every 28 days. Every patient was treated with at least 2 cycles and a median of 3 cycles （2-6 cycles ）. Results： Five patients achieved complete response （11.1%） and 18 partial response （40.0%）, 10 stable disease （22.2%）. The overall response rate was 51.1%. The clinical disease control rate was 73.3%, median time to tumor progression （TTP） was 7.8 months （1.0-34.5 months）, median survival time was 17.6 months （range 1.9-48.0 months）, and one year survival rate was 65.2%. The main side effect was marrow suppression. The treatment was well tolerated with grades Ⅲ and Ⅳ leukopenia in nine （20%） and ten （22.2%） patients. Conclusion： Combinative chemotherapy of docetaxel and cisplatin has a good anti-tumor activity on refractory advanced breast cancer with manageable toxicity.

Efficacy and safety of trastuzumab combined with chemotherapy for first-line treatment and beyond progression of HER2-overexpressing advanced breast cancer

Objective： To observe the efficacy and safety of trastuzumab combined with chemotherapy in patients with human epidermal growth factor receptor 2 （HER2）-overexpressing advanced breast cancer. Methods： A total of 90 patients with HER2-overexpressing advanced breast cancer were enrolled in this study. All patients were diagnosed with ductal invasive breast cancer by pathological analysis, and were aged between 31-73 years with a median of 51 years. HER2-positivity was defined as 3（＋） staining in immunochemistry or amplification of fluorescence in situ hybridization （FISH, ratio ≥2.0）. Trastuzumab was administered in combination with chemotherapy as first-line treatment and beyond progression as a second- line, third-line, and above treatment in 90, 34, 14, and 6 patients, respectively. The chemotherapy regimen was given according to normal clinical practice. The response rate was evaluated every two cycles, and the primary endpoints were progression-free survival （PFS） and overall survival （OS）. Survival curves were estimated by using Kaplan-Meier graphs and were compared by using log-rank test statistics. Multivariate analysis was done using Cox＇s proportional hazards regression model, and the level of significance was P〈0.05. Results： All 90 patients received at least one dose of trastuzumab, and efficacy could be evaluated in 85 patients. The median follow-up was 50 months. In total, 72 （80.00%） patients had visceral metastasis, and 43 （47.78%） patients had progressed after one or more extensive chemotherapy regimens for metastatic diseases. The median PFS for first-line trastuzumab was 10 months （range, 2-59 months）, and the median OS after metastasis or initially local advanced disease was 22 months （range, 2-1 16 months）. Conclusions： Trastuzumab combined with chemotherapy was active and well-tolerated as a first-line treatment and even beyond progression in HER2-overexpressing advanced breast cancer as a second-line or third-line treatment. However, its efficacy is certainly less beyond this point.

Decrease in the Ki67 index during neoadjuvant chemotherapy predicts favorable relapse-free survival in patients with locally advanced breast cancer

Objective: The purpose of this study was to explore the optimal cutoffs of the three parameters of Ki67 during NAC for predicting patient prognosis and investigate whether the optimal cutoffs of the Ki67 values were associated with relapse-free survival(RFS) or breast cancer-specific survival(BCSS).Methods: A total of 92 patients with locally advanced breast cancer(LABC), who had residual disease after NAC were retrospectively investigated.The optimal cutoff values of the Ki67 parameters were assessed by the online algorithm Cutoff Finder.Kaplan-Meier analysis, the log-rank test and Cox regression analysis were carried out to analyze survival.Results: The optimal cutoff values for the postsurgical Ki67 level and the decrease in the Ki67 level during NAC were defined as 25% and 12.5%, respectively.According to the univariate survival analysis, a higher Ki67 level in residual disease was associated with poor RFS(P = 0.004) and BCSS(P = 0.014).In addition, a Ki67 expression decrease > 12.5% during NAC was related to favorable RFS(P = 0.007), but was not related to BCSS(P = 0.452).Cox regression analysis showed that the Ki67 expression decrease(> 12.5% vs.≤ 12.5%) and histological grade(grade 3 vs.grade 1-2) were the independent factors associated with RFS(P =0.020 and P = 0.023, respectively), with HR values of 0.353(95% CI: 0.147-0.850) and 3.422(95% CI: 1.188-9.858), respectively.Conclusions: The Ki67 decrease was one of the independent factors associated with RFS in LABC patients with residual disease after receiving NAC.

Association between HER2 status and response to neoadjuvant anthracycline followed by paclitaxel plus carboplatin chemotherapy without trastuzumab in breast cancer

Background： We recently showed HER2-positive breast cancers are less likely to respond to neoadjuvant anthracycline chemotherapy. Here, we investigated whether HER2-positive breast cancers responded to sequential neoadjuvant anthracycline followed by paclitaxel plus carboplatin regimen in the absence of trastuzumab. Methods： Women （n=372） with operable primary breast cancer initially received two cycles of neoadjuvant anthracyclines, the clinical tumor response was assessed, then patients were received four cycles of paelitaxel plus carboplatin regimen. All the patients did not received trastuzumab treatment in the neoadjuvant setting. HER2 status was determined by immunohistochemistry and/or by fluorescence in situ hybridization in core- biopsy breast cancer tissue obtained before the neoadjuvant chemotherapy. Results： Eighteen percent （67/372） of patients achieved a pathologic complete response （pCR） in their breast. HER2-positive tumors had a significant higher pCR rate than HER2-negative tumors （33.0% versus 13.5%, P〈0.001） in this cohort of 372 patients, and positive HER2 status remained an independent favorable predictor of pCR in a multivariate analysis [odds ratio （OR）, 2.26; 95% confidence interval （CI）, 1.18 to 4.36, P=0.015]. Furthermore, patients who responded to initial anthracycline regimens were more likely to respond to paclitaxel plus carboplatin than patients who did not （pCR, 27.2% versus 14.6%, P=0.005）. Patients with HER2-positive tumors exhibited a significant higher pCR rate than did patients with HER2- negative tumors in both anthracycline response group （40.5% versus 20.0%, P=0.025） and anthracycline non-response group （28.3% versus 11.3 %, P=0.002）. Conclusions： Under the circumstance of no trastuzumab treatment, women with HER2-positive cancers derive a large benefit from paclitaxel-carboplatin-based neoadjuvant chemotherapy.

Hormonal therapy might be a better choice as maintenance treatment than capecitabine after response to first-line capecitabine-based combination chemotherapy for patients with hormone receptor-positive and HER2-negative,metastatic breast cancer

Background:Both hormonal therapy(HT) and maintenance capecitabine monotherapy(MCT) have been shown to extend time to progression(TTP) in patients with metastatic breast cancer(MBC) after failure of taxanes and anthracycline?containing regimens.However,no clinical trials have directly compared the efficacy of MCT and HT after response to first?line capecitabine?based combination chemotherapy(FCCT) in patients with hormone receptor(HR)?positive and human epidermal growth factor receptor 2(HER2)?negative breast cancer.Methods:We retrospectively analyzed the charts of 138 HR?positive and HER2?negative MBC patients who were in non?progression status after FCCT and who were treated between 2003 and 2012 at the Cancer Institute and Hospital,Chinese Academy of Medical Sciences,in Beijing,China.The median number of first?line chemotherapy cycles was 6(range,4–8);combined agents included taxanes,vinorelbine,or gemcitabine.Of these 138 patients,79 received MCT,and 59 received HT.Single?agent capecitabine was administered at a dose of 1250 mg/m2 twice daily for 14 days,followed by a 7?day rest period,repeated every 3 weeks.Of the 59 patients who received HT,37 received aromatase inhibitors(AIs),8 received selective estrogen receptor modulators(SERMs),and 14 received goserelin plus either AIs or SERMs.We then compared the MCT group and HT group in terms of treatment efficacy.Results:With a median follow?up of 43 months,patients in the HT group had a much longer TTP than patients in the MCT group(13 vs.8 months,P ease?free surviv= 0.011).When TTP was adjusted for age,menopausal status,Karnofsky performance status score,disal,site of metastasis,number of metastatic sites,and response status after FCCT,extended TTP was still observed for patients in the HT group(hazard ratio:0.63;95% confidence interval:0.44–0.93;P = 0.020).We also observed a trend of overall survival advantage for patients in the HT group vs.patients in the MCT group,but the difference was not significant(43 vs.37 months,P tients in the MCT g= 0.400).In addition,patients in the HT group gen?erally tolerated the treatment well,whereas paroup experienced grades 3–4 adverse events,the most frequent of which were hand?foot syndrome(15.8%) and hematologic abnormalities(7.6%).Conclusion:For HR?positive and HER2?negative MBC patients,HT might be considered a treatment after response to FCCT but prior to MCT as a long?term administration.

Dose-dense paclitaxel plus carboplatin vs.epirubicin and cyclophosphamide with paclitaxel as adjuvant chemotherapy for high-risk triple-negative breast cancer

Objective:The objective of this open-label,randomized study was to compare dose-dense paclitaxel plus carboplatin(PCdd)with dose-dense epirubicin and cyclophosphamide followed by paclitaxel(ECdd-P)as an adjuvant chemotherapy for early triple-negative breast cancer(TNBC).Methods:We included Chinese patients with high recurrence risk TNBC who underwent primary breast cancer surgery.They were randomly assigned to receive PCdd[paclitaxel 150 mg/m2 on d 1 and carboplatin,the area under the curve,(AUC)=3 on d 2]or ECdd-P(epirubicin 80 mg/m2 divided in 2 d and cyclophosphamide 600 mg/m2 on d 1 for 4 cycles followed by paclitaxel 175 mg/m2 on d 1 for 4 cycles)every 2 weeks with granulocyte colony-stimulating factor(G-CSF)support.The primary endpoint was 3-year disease-free survival(DFS);the secondary endpoints were overall survival(OS)and safety.Results:The intent-to-treat population included 143 patients(70 in the PCdd arm and 73 in the ECdd-P arm).Compared with the ECdd-P arm,the PCdd arm had significantly higher 3-year DFS[93.9%vs.79.1%;hazard ratio(HR)=0.310;95%confidence interval(95%CI),0.137-0.704;log-rank,P=0.005]and OS(98.5%vs.92.9%;HR=0.142;95%CI,0.060-0.825;log-rank,P=0.028).Worse neutropenia(grade 3/4)was found in the ECdd-P than the PCdd arm(47.9%V5.21.4%,P=0.001).Conclusions:PCdd was superior to ECdd-P as an adjuvant chemotherapy for early TNBC with respect to improving the 3-year DFS and OS.PCdd also yielded lower hematological toxicity.Thus,PCdd might be a preferred regimen for early TNBC patients with a high recurrence risk.

Weekly taxane-anthracycline combination regimen versus tri-weekly anthracycline-based regimen for the treatment of locally advanced breast cancer:a randomized controlled trial

Background:Extensive studies have confirmed the efficacy of taxanes in combination with anthracycline-based chemotherapy on breast cancer.However,few studies have assessed the efficacy of weekly taxane-anthracycline regimens on locally advanced breast cancer.This study was to compare the efficacy and safety of a weekly taxaneanthracycline regimen with those of tri-weekly anthracycline-based regimen in patients with locally advanced breast cancer.Methods:Patients with locally advanced breast cancer were randomized to receive 4-6 cycles of neoadjuvant chemotherapy with tri-weekly 5-fluorouracil-epirubicin-cyclophosphamide(FEC) regimen or weekly paclitaxel-epirubicin(PE) regimen.The primary endpoint was the pathologic complete response(pCR) rate.Other endpoints included the clinical tumor response,breast-conserving surgery rate,and adverse events.Results:Between March 2010 and September 2013,293 patients were randomized to the FEC(n=151) and PE(n=142) arms.The overall clinical response rate was significantly higher in the PE arm than in the FEC arm(76.06%vs.59.95%,P=0.001).Consistently,the post-chemotherapy pathologic T and N stages were significantly lower in the PE arm than in the FEC arm(P<0.001).However,the pCR rate was similar in the two arms(10.61%vs.12.31%,P=0.665).Overall,36(27.27%) patients in the FEC arm and 6(35.28%) in the PE arm were qualified for breast-conserving surgery.Most adverse events were comparable in both arms,with more severe neutropenia in the PE arm than in the FEC arm(11.97%vs.5.96%,P=0.031).Conclusions:In patients with locally advanced breast cancer,weekly PE was not superior to FEC in terms of pCR.However,weekly PE has a higher response rate and superior down-staging effects.On this account,the PE regimen may be considered an alternative option for locally advanced breast cancer.Long-term follow-up data are needed to confirm the efficacy of this regimen on locally advanced breast cancer.Trial registration Chinese clinical trial registry,ChiCTR-TRC-10001043,September 21。

The short-time effects of chemotherapy with combinations of hydroxycamptothecine and oxaliplatin in treatment of advanced colorectal cancer

Objective： Although 5-fluarouracil-based chemotherapy has become a standard regimen for treatment of advanced colorectal cancer, the efficacy, as second line therapy, is not high. It is necessary to find a new regimen as a substitute for these patients. The study was to evaluate the short-time effects and toxicity of combination of HCPT plus L-OHP regimen in treatment of advanced colorectal cancer. Methods： Forty-seven patients with pathological evidence of advanced colorectal cancer were enrolled and were treated with HCPT plus L-OHP regimen for 86 cycles. All patients were treated with L-OHP 130 mg/m^2 day 1 and HCPT 6 mg/m^2day 1-4, the chemotherapy was repeated every 3 weeks as a cycle. The Short-time efficats and side effects were evaluated after 2 cycles for each patient. Results： 38 cases can be evaluated to short-time effects and achieved the overall response rate （CR＋PR） was 36.8%. KPS improved in 20 cases （52.6%）. In the total 86 cycles, the leucopenia occurred in 59 cycles （68.6%）,18 cycles （30.5%） in grade Ⅲ and Ⅳ and the diarrhea occurred in 48 cycles （55.8%）, 18 cycles （37.5%） in grade Ⅲ and Ⅳ. Conclusion： A satisfied response rate was obtained in advanced colorectal cancer patients treated by HCPT plus L-OHP regimen, especially who were the failure of first-line chemotherapy with 5-FU. The limited-dose toxicity was leucopenia and diarrhea.

Gemcitabine Based Combination Regimens for Treatment of Refractory Advanced Breast Cancer

Objective： Anthracycline and taxane are the standard agents in combined chemotherapy of advanced breast cancer. However, when these agents based chemotherapy is failure, the selection of salvage regimen is still of problem. Gemcitabine, an active agent in both lung cancer and pancreas cancer, is demonstrated effective in breast caner. But there have been relatively less data of gemcitabine in anthracycline and/or taxane-resistant breast cancer. Therefore we employe this study to explore the efficacy and safety of gemcitabine based combination regimen in this population. Methods： From May 2002 to March 2006, 28 patients with measurable lesion of advanced metastatic breast cancer who were resistant to prior anthracycline and taxane based chemotherapy were enrolled. Patients were treated with gemcitabine based combination chemotherapy with a median cycles of 3 （range 2-6）. Results： The overall response rate was 28.6% （8/28）, with 1 CR （Complete response 3.5%） and 7 PRs （Partial response 25%）. Stable disease was seen in 8 patients （28.6%） while disease progressed in 12 patiens （42.8%）. The median time to progression was 4.5 m （range, 2-23 m）. The main toxicity included bone marrow depression, alopecia, mucositis and peripheral neurotoxicity. The grade 3 to 4 clinical adverse effect was leukopenia in 5 cases （17.9%） and thrombocytopenia in 8 cases （30%）. Conclusion： Gemcitabine based combination regimens is feasible in anthracycline and taxane-resistant advanced breast cancer. The clinical response and TTP is acceptable with limited toxicity pattern.

EFFECT OF NEOADJUVANT CHEMOTHERAPY USING PACLITAXEL COMBINED WITH CARBOPLATIN ON ADVANCED NON-SMALL CELL LUNG CANCER

Objeetive： To assess the therapeutic effectiveness of preoperative neoadjuvant chemotherapy using a combination of paclitaxel and carboplatin on local advanced non-small cell lung cancer （NSCLC）. Methods： Twenty-five patients with advanced NSCLC were treated with paclitaxel and carboplatin for 2 to 4 cycles before undergoing tumor resection and then postoperative chemotherapy/radiotherapy therapy for 2 to 4 cycles. Results： Following neoadjuvant chemotherapy, the most prominent side-effect was bone marrow restraint. The overall response rate of preoperative chemotherapy was 56%. The mean survival time was 26.5 months, with 1-, 2- and 5-year survival rates of 55%, 25%, and 16%, respectively. All NSCLC patients survived the perioperative period. Conclusion： Preoperative neoadjuvant chemotherapy combining paclitaxel and carboplatin produced minimal side-effect while increasing the probability that advanced NSCLC patients would be able to undergo surgery thus improving their prognosis.

Oncoplastic Breast Surgery after Neoadjuvant Chemotherapy Replacing Mastectomy in Locally Advanced Breast Cancer (LABC): Single Institute Experience

Background: Integration of neoadjuvant chemotherapy (NCT) in early 70s resulted that many LABC tumors become resectable but with total mastectomy especially those with partial response, oncoplastic techniques give better oncological outcome with better cosmetic results. Objective: We evaluate the oncological safety of oncoplastic breast surgery (OS) in LABC showing partial response to NCT. Methods: We prospectively analyzed the data of 32 out of 58 patients with LABC who showed partial response to NCT and could have conservative surgery with advanced oncoplastic techniques rather than total mastectomy. Results: Out of 58 patients with LABC, received neoadjuvant chemotherapy, complete response was observed in 8 patients (13%), partial response reported in 32 (55.1%) cases, 12 patients (20%) had stable disease and 6 patients (10%) showed progressive disease. Data of 32 cases were studied (mean age 44.84 ± 9.10 years;range 26 - 59 years). Inferior pedicle was performed in 9 cases, mini LD flap in 3 patients, 5 had Grissotti technique, 6 with superomedial pedicle, 4 had V mammoplasty and 3 with J mammoplasty and 2 had vertical mammoplasty. Margins were positive in 5 cases (15.6%) with mean margin width 9.63 ± 5.72 (range 0 - 22 mm), and the local recurrence was reported in 2 cases (6.2%). Complications were reported in 3 cases (9.3%). The follow up was 1.67 ± 1.03 (range 0 - 3.3 years). Conclusions: Integration of neoadjuvant chemotherapy together with advanced oncoplastic techniques opens a new way for management of LABC especially those showing partial response with avoidance of total mastectomy, and comparable oncological safety in addition to better aesthetic and psychological outcome.

Evaluation of dynamic contrast-enhanced MRI in monitoring early response of locally advanced breast cancer to neoadjuvant chemotherapy

Objective： The aim of our study was to assess the value of dynamic contrast-enhanced magnetic resonance imaging （DMRI） in predicting early response to neoadjuvant chemotherapy （NAC） in patients with locally advanced breast cancer （LABC） and to assess the accuracy of DMRI in evaluating residual disease after NAC. Methods： DMRI were per- formed in 43 women with LABC （44 lesions, all were invasive ductal carcinoma） before, after the first and final cycle of NAC. Tumour volume, early enhanced ratio （El）, maximum enhanced ratio （Emax）, and maximum enhanced time （Tmax）, dynamic signal intensity-time curve were obtained during treatment. Residual tumour volumes obtained using DMRI were compared with pathological findings to assess the accuracy of DMRI. Results： After 1st cycle of NAC, the mean volume of responders decreased insignificantly, P 〉 0.05, but after NAC, mean volume of residual tumor decreased significantly （P 〈 0.01）. Morphol- ogy change： 29 cases showed a concentric shrinkage pattern while 7 cases showed a dendritic shrinkage pattern. Significant differences were found in El, Emax and Tmax between responders and non-responders （P 〈 0.05）. After 1st cycle of NAC, El, Emax and Tmax of responders changed significantly （P 〈 0.001）; while there is no significant change in non-responders （P 〉 0.05）. After NAC, dynamic signal intensity-time types were changed in responders, and tended to be significantly flat- tening, while no significant change was found in non-responders. The residual tumour volume correlation coefficient between DMRI and pathology measurements was very high （r = 0.866, P = 0.000）. Conclusion： DMRI is useful to evaluate the early response to NAC in LABC. The presence and volume of residual disease in LABC patients treated with NAC could be ac- curately evaluated by DMRI.

Evaluation of the effect of neoadjuvant chemotherapy on tumor and axillary lymph nodes in locally advanced breast cancer: a study of 50 patients

Objective： The purpose of the study was to correlate between effect of pre-neoadjuvant chemotherapy （NACT） and post-NACT clinical, sonographic and pathologic features of the tumor and axillary lymph nodes （ALNs） and to raise the possibility of applying the concept of sentinel lymph node biopsy （SLNB） in patients with initially positive ALNs before NACT. Methods： A prospective study of 50 female patients with locally advanced breast cancer （LABC） with clinically palpable.and cytologically （under ultrasonographic guidance） positive ALNs. All patients received NACT and then referred for ultrasono- graphic assessment of the axilla regarding any detectable sonographic criteria of metastatic deposits in ALNs as well as the tumor size in relation to its prechemotherapy size, All patients were then subjected either to modified radical mastectomy or breast conserving surgery. The clinical, sonographic and pathological response of the tumor and the ALNs were documented, classified and correlated with each other. Results： Patients＇ mean age was 47.7±9.1 years. The mean clinical tumor size was 6.7 ± 1.4 cm; stage IliA that was presented in 32 patients （64%） and IIIB was presented in 18 patients （36%）. Chemotherapy was given for a median of 4 cycles, there was reduction of the mean clinical tumor size from 6.7 ± 1.4 cm to 4.3 ± 2.7 cm （P 〈 0.001）. Clinical response was complete in 5 （10%） tumors, complete pathological tumor response （post-neoadjuvant） was detected in 6 （16%） of patients. Complete clinical nodal response （post-neoadjuvant） in 23 （46%） axillae, on sonographic assessment of the axilla, response was complete in 17 （34%） axillae. Complete pathological nodal response occurred in 16 （32%） axillae. Out of 17 axillae that showed complete sonographic response 11 axillae showed complete pathological nodal response （P 〈 0.001）. Conclusion： Formal axillary lymph node dissection can be avoided and replaced by SLNB post NACT in patients with LABC with metastatic ALNs if there were complete clinical and sonographic criteria of nodal response as well as complete pathological tumor response.

Effect of Xiao Chaihu Tang combined with intravenous chemotherapy on tumor markers and immune function in patients with advanced breast cancer

Objective:To study the effect of Xiao Chaihu Tang combined with intravenous chemotherapy on tumor markers and immune function in patients with advanced breast cancer.Methods: 76 patients with advanced breast cancer treated in our hospital between May 2012 and November 2015 were collected and divided into the combined treatment group (n=34) who accepted Xiao Chaihu Tang combined with intravenous chemotherapy and the control group (n=42) who accepted intravenous chemotherapy alone according to different treatment, and the treatment cycle was 3 months for both groups. Before treatment and 3 months after treatment, ELISA method was used to detect serum levels of broad-spectrum tumor markers and breast cancer-specific tumor markers;flow cytometer was used to detect cellular immune function index levels, and turbidimetric immunoassay was used to detect humoral immune function index levels in peripheral blood.Results: Before treatment, differences in serum tumor marker levels as well as cellular immunity and humoral immunity index levels in peripheral blood were not statistically significant between two groups of patients (P>0.05);after 3 months of treatment, broad-spectrum tumor markers carcinoembryonic antigen (CEA), carbohydrate antigen 153 (CA153) and carbohydrate antigen 125 (CA125) levels in serum of combined treatment group were lower than those of control group, and breast cancer-specific tumor markers insulin-like growth factor-1 (IGF-1), midkine (MK), soluble E-cadherin (sEC) and thymidine kinase 1 (TK1) levels were lower than those of control group (P<0.05);CD3+ and CD4+ T lymphocyte levels as well as CD4+/CD8+ ratio in peripheral blood of combined treatment group were higher than those of control group while CD8+ T lymphocyte level was lower than that of control group, and immunoglobulin G (IgG), immunoglobulin A (IgA) and immunoglobulin M (IgM) levels in peripheral blood were higher than those of control group (P<0.05).Conclusions:Xiao Chaihu Tang combined with intravenous chemotherapy can decrease the severity of advanced breast cancer and optimize the body's immune function.

Efficacy and safety of albumin-bound paclitaxel in treating recurrent advanced non-small-cell lung cancer

Objective： To observe the efficacy and safety of albumin-bound paclitaxel （ABP） monotherapy in treating recurrent advanced non-small-cell lung cancer （NSCLC）. Methods： We retrospectively analyzed the short-term efficacy and toxicities of ABP monotherapy in treating 21 patients who had previously undergone multiple cycles of therapy for their advanced NSCLC in our hospital since 2010. The treatment-related survival was also analyzed. Results： Of these 21 patients, the best overall response was partial response （PR） in 6 patients （28.6%）, stable disease （SD） in I0 patients （47.6%）, and progressive disease （PD） in 5 patients （23.8%）. The overall response rate （ORR） was 28.6% and the disease control rate （DCR） （PR ＋ SD） was 76.2%. The median progression-flee survival （PFS） was 4.0 months （95% CI, 5.0-7.0 months）. The main grade 3/4 toxicities included neutropenia （11.1%）, peripheral nerve toxicity （5.6%）, muscle and joint aches （5.6%）, and fatigue （5.6%）. Conclusions： The ABP monotherapy can achieve good objective response in advanced NSCLC patients who have previously received multiple cycles of treatment and be well tolerated.

Systemic chemotherapy for metastatic breast cancer

Breast cancer is the leading cause of cancer among women worldwide and the most common cancer in China. Many factors influence the treatment strategy for metastatic breast cancer （MBC）. Chemotherapy should be administered to patients with hormone receptor-negative tumors, symptomatic visceral metasta- sis, and a short disease-free interval. Sequential single-agent chemotherapy has similar efficacy as combi- nation agents in terms of overall survival and quality of life. Anthracyclines are the cornerstone of first-line treatment for MBC, and taxanes represent the second treatment option after resistance. When progression or intolerable toxicity occurs after optimal treatment, the alternative treatments include capecitabine, vinorel- bine, and gemcitabine. Ixabepilone and eribulin are relatively new effective single agents. A combination of cytotoxic agents for patients with rapid clinical progression can further improve the overall response rate and time to progression compared to single-agent treatment. For patients with MBC who were pretreated with anthracyclines in the neoadjuvant/adjuvant setting, a taxane-containing regimen such as docetaxel plus capecitabine or gemcitabine plus paclitaxel should be administered. Platinum-based therapies such as cisplatin or carboplatin have a role in the treatment of triple-negative breast cancer. Meanwhile, the efficacy of the addition of targeted drugs such as iniparib, bevacizumab, and catuximab to chemotherapy remains unproven. Maintenance chemotherapy is routinely recommended in clinical practice at present. Patients who were previously treated with paclitaxel and gemcitabine have better progression-free and overall sur- vival with maintenance chemotherapy according to a Korean phase III clinical trial. Sequential maintenance treatment with capecitabine monotherapy after capecitabine-based combination chemotherapy （X-based X） appears favorable based on a series of domestic studies.

Adjuvant Chemotherapy of Gemcitabine plus Carboplatin versus Paclitaxel plus Carboplatin in Patients with Resected Non-Small Cell Lung Cancer

Background: This retrospective study was to evaluate the efficacy and toxicity of gemcitabine plus carboplatin (GC regimen) and paclitaxel plus carboplatin (PC regimen) combination chemotherapy administered as an adjuvant therapy after complete resection of non-small cell lung cancer. Methods: Forty-four patients (GC regimen, n = 29;PC regimen, n = 15) received gemcitabine at a dose of 1000 mg/m2 on days 1 and 8, and carboplatin with the target dose of area under the curve (AUC) of 4 on day 8 every 28 days and paclitaxel at a dose of 70 mg/m2 on days 1, 8 and 15, and carboplatin with the target dose of AUC of 5 on day 1 every 28 days. Results: A total of 130 cycles of the treatment were administered (averaged, 3.1 in GC arm and 2.7 cycles in PC arm). Forty-three patients (97.7%) completed the scheduled cycles. One patient (2.3%) was discontinued due to grade 4 pneumonia. The dose was reduced in 2 patients (4.5%) due to grade 4 thrombocytopenia. Grade 3/4 neutropenia was significantly observed in the PC group (GC: 12/29, 41.4%;PC: 11/15, 73.3%, p = 0.0443). The nonhematological toxicities were mild. Grade 1/2 alanine aminotransferase and aspartate aminotransferase in the GC group was significantly observed higher compared to those of the PC group (GC: 20/29, 69.0%;PC: 4/15, 26.7%, p = 0.0076). Grade 1/2 alopecia was significantly observed in the PC group (GC: 0/25, 0.0%;PC: 13/15, 86.7%, p 0.0001). There was no treatment-related death. The median survival time (MST) of the entire GC group was 784 days, the 3-year overall survival (OS) was 75.9%, and 3-year recurrence-free survival (RFS) was 65.5%. The MST of the entire PC group was 963 days, the 3-year OS was 80.0%, and the 3-year RFS was 60.0%. Conclusion: These results demonstrate that the GC and PC combination chemotherapies are efficacious and feasible regimens, which should be considered as one of the standard therapies for adjuvant therapy.

Effect of Astragalus Injection Combined with Chemotherapy on Qual ity of Life in Patients with Advanced Non-small Cell Lung Cancer

Objective: To observe the effect of Astragalus injection (AI) combined with chemotherapy on quality of life (QOF) in patients with advanced non-small cell lung caner (NSCLC). Methods: Sixty NSCLC patients were randomly divided into the treated group (n=30,treated with AI combined with chemotherapy) and the control group (n=30, treated with chemotherapy alone). Chemotherapy of MVP protocol was applied to both groups. AI was supplemented to the treated group by intravenous dripping 60 ml per day. Treatment of 21-28 days consisted one treatment cycle, and 2-3 cycles were applied. WResults: The effective rate in the treated group was 40.0% and in the control group was 36.7%, the mean remission rate in them being 5.4 month s and 3.3 months, the median survival period 11 month and 7 month and the 1-year survival rate 46.75% and 30.0%, respectively, the difference of these indexes between the two groups were all significant (P<0 05). Moreover, the clinical improving rate and QOF elevation rate in the treated group was 80.4% and 43.3%, as compared with those in the control group (50.0% and 23.3% respectively), the different was also significant (P<0 01). Conclusion: AI combined with chemotherapy can significantly improve the QOF in NSCLC patients of advanced stage.

Paclitaxel-associated reticulate hyperpigmentation:Report and review of chemotherapy-induced reticulate hyperpigmentation

Drug-induced reticulate hyperpigmentation is uncommon. Including the patient described in this report, chemotherapy-associated reticulate hyperpigmentation has only been described in ten individuals. This paper describes the features of a woman with recurrent and metastatic breast cancer who developed paclitaxelinduced reticulate hyperpigmentation and reviews the characteristics of other oncology patients who developed reticulate hyperpigmentation from their antineoplastic treatment. A 55-year-old Taiwan Residents woman who developed reticulate hyperpigmentation on her abdomen, back and extremities after receiving her initial treatment for metastatic breast cancer with paclitaxel is described. The hyperpigmentation became darker with each subsequent administration of paclitaxel. The drug was discontinued after five courses and the pigment faded within two months. Pub Med was searched with the key words: Breast, cancer, chemotherapy, hyperpigmentation, neoplasm, reticulate, tumor, paclitaxel, taxol. The papers generated by the search, and their references, were reviewed. Chemotherapy-induced reticulate hyperpigmentation has been described in four men and six women. Bleomycin, cytoxan, 5-fluorouracil, idarubacin, and paclitaxel caused the hyperpigmentation. The hyperpigmentation faded in 83% of the patients between two to six months after the associated antineoplastic agent was discontinued. In conclusion, chemotherapy-induced reticulate hyperpigmentation is a rare reaction that may occur during treatment with various antineoplastic agents. The hyperpigmentation fades in most individuals once thetreatment is discontinued. Therefore, cancer treatment with the associated drug can be continued in patients who experience this cutaneous adverse event.
