RESUMO

BACKGROUND: The addition of pertuzumab to trastuzumab plus standard chemotherapy as adjuvant therapy following surgery significantly improved invasive disease-free survival (IDFS) in patients with HER2-positive early breast cancer in the multinational randomized APHINITY trial (NCT01358877, BIG 4-11/BO25126/TOC4939G). We analyzed clinical outcomes in the subgroup of patients recruited at Chinese sites. METHODS: Patients were randomized to standard adjuvant chemotherapy plus 1 year of trastuzumab with pertuzumab or placebo. Patients recruited in mainland China, Hong Kong and Taiwan are included in this descriptive analysis. RESULTS: Chinese patients had similar demographic characteristics to the global population, but a higher proportion had nodal involvement. Although this subgroup analysis was not powered to detect statistical significance, a numerical improvement in IDFS was observed with the addition of pertuzumab to trastuzumab in Chinese patients (hazard ratio, 0.69; 95% confidence interval: 0.39-1.19; 3-year IDFS event-free estimates 92.5% [pertuzumab] and 91.7% [placebo]), which was consistent with the primary analysis of the global population. Further subgroup analyses showed numerical improvements in the Chinese node-positive, hormone receptor-negative and -positive subgroups, although confidence intervals were wide due to the low number of events. The incidence of diarrhea was higher in the pertuzumab arm, and no primary cardiac events occurred in Chinese patients in either arm. CONCLUSIONS: Pertuzumab, used in combination with trastuzumab and chemotherapy in APHINITY, is effective as an adjuvant treatment regimen for Chinese patients with HER2-positive early breast cancer in a setting with curative intent. The safety profile in Chinese patients was consistent with that of the global population.

RESUMO

Breast cancer is the most common malignant tumor among women in the world. In 2005, there were approximately 272,000 new cases diagnosed and more than 70,000 deaths from breast cancer in China. Of the patients who are newly diagnosed with breast cancer each year, approximately 3% to 10% have distant metastases at the time of diagnosis. Of those who have early stage disease at diagnosis, from 30% to 40% will develop advanced breast cancer. The 5-year survival rate for patients with advanced breast cancer is only 20%, and the median overall survival (OS) is 2 to 3 years. Although advanced breast cancer is still difficult to cure, physicians can relieve clinical symptoms, improve quality of life, and further prolong survival through the development of new drugs and the optimization model of treatment. Patients with advanced breast cancer have their own preferences in the choice of treatment options. Moreover, there is no standard recommendation for the treatment of refractory breast cancer after multiline therapy. To offer a reference for clinicians, a Chinese expert group has analyzed, summarized, and discussed related research data on the diagnosis, treatment, and prognosis of inoperable, locally advanced breast cancer and recurrent or metastatic breast cancer and has developed the Chinese expert consensus on the clinical diagnosis and treatment of advanced breast carcinoma (2018).

RESUMO

BACKGROUND: The current exploratory analysis was performed to evaluate the efficacy and safety of everolimus for treatment of human epidermal growth factor receptor 2-positive (HER2+) advanced breast cancer in the Asian subset of patients in the BOLERO-1 trial. METHODS: Postmenopausal women with HER2+ advanced breast cancer, who had not received systemic therapy for advanced disease, were randomized 2:1 to receive everolimus or placebo, plus trastuzumab and paclitaxel. The two primary end points were investigator-assessed progression-free survival (PFS) in the full population and in the hormone receptor-negative (HR-) subpopulation. Secondary end points included assessment of the objective response rate, the clinical benefit rate, and safety. RESULTS: In the Asian subset, median PFS was similar in the everolimus (n = 198) and placebo (n = 105) arms in the full analysis set (hazard ratio = 0.82 (95% CI 0.61-1.11)). In the HR- subpopulation, everolimus prolonged median PFS by 10.97 months vs placebo (25.46 vs 14.49 months; hazard ratio = 0.48 (95% CI 0.29-0.79)). In the everolimus arm of the Asian subset, the most common adverse events of any grade were stomatitis (62.2%), diarrhea (48.0%), rash (43.4%) and neutropenia (42.3%). Neutropenia (grade 3: 27.6%; grade 4: 4.6%) and decreased neutrophil count (grade 3: 11.2%; grade 4: 3.6%) were the most frequent grade 3/4 adverse events. Serious adverse events included pneumonia (5.1%), pneumonitis (3.1%), and interstitial lung disease (3.1%). There were three deaths (1.5%) during treatment in the everolimus arm vs none in the placebo arm. CONCLUSIONS: The efficacy and safety of everolimus plus trastuzumab and paclitaxel as first-line treatment for HER2+ advanced breast cancer in the Asian subset was consistent with that reported previously in the overall population.

RESUMO

BACKGROUND: mTOR inhibition reverses trastuzumab resistance via the hyperactivated PIK/AKT/mTOR pathway due to PTEN loss, by sensitising PTEN-deficient tumours to trastuzumab. The BOLERO-1 study assessed the efficacy and safety of adding everolimus to trastuzumab and paclitaxel as first-line treatment for patients with HER2-positive advanced breast cancer. METHODS: In this phase 3, randomised, double-blind trial, patients were enrolled across 141 sites in 28 countries. Eligible patients were aged 18 years or older, with locally assessed HER2-positive advanced breast cancer, with Eastern Cooperative Oncology Group (ECOG) performance status of 0-1, who had not received previous trastuzumab or chemotherapy for advanced breast cancer within 12 months of randomisation, had measurable disease as per Response Evaluation Criteria in Solid Tumors (RECIST) or bone lesions in the absence of measurable disease, without previous systemic treatment for advanced disease except endocrine therapy. Patients were randomly assigned (2:1) with an interactive voice and web response system to receive either 10 mg everolimus once a day orally or placebo plus weekly trastuzumab intravenously at 4 mg/kg loading dose on day 1 with subsequent weekly doses of 2 mg/kg of each 4 week cycle plus paclitaxel intravenously at a dose of 80 mg/m(2) on days 1, 8, and 15 of each 4 week cycle. Randomisation was stratified according to previous use of trastuzumab and visceral metastasis. Patients and investigators were masked to the assigned treatments. Identity of experimental treatments was concealed by use of everolimus and placebo that were identical in packaging, labelling, appearance, and administration schedule. The two primary objectives were investigator-assessed progression-free survival in the full study population and in the subset of patients with hormone receptor-negative breast cancer at baseline; the latter was added during the course of the study, before unmasking based on new clinical and biological findings from other studies. All efficacy analyses were based on the intention-to-treat population. Enrolment for this trial is closed and results of the final progression-free survival analyses are presented here. This trial is registered with ClinicalTrials.gov, number NCT00876395. FINDINGS: Between Sept 10, 2009, and Dec 16, 2012, 719 patients were randomly assigned to receive everolimus (n=480) or placebo (n=239). Median follow-up was 41·3 months (IQR 35·4-46·6). In the full population, median progression-free survival was 14·95 months (95% CI 14·55-17·91) with everolimus versus 14·49 months (12·29-17·08) with placebo (hazard ratio 0·89, 95% CI 0·73-1·08; p=0·1166). In the HR-negative subpopulation (n=311), median progression-free survival with everolimus was 20·27 months (95% CI 14·95-24·08) versus 13·08 months (10·05-16·56) with placebo (hazard ratio 0·66, 95% CI 0·48-0·91; p=0·0049); however, the protocol-specified significance threshold (p=0·0044) was not crossed. The most common adverse events with everolimus were stomatitis (314 [67%] of 472 patients in the everolimus group vs 77 [32%] of 238 patients in the placebo group), diarrhoea (267 [57%] vs 111 [47%] patients), and alopecia (221 [47%] vs 125 [53%]). The most frequently reported grade 3 or 4 adverse events in the everolimus group versus the placebo group were neutropenia (117 [25%] vs 35 [15%]), stomatitis (59 [13%] vs three [1%]), anaemia (46 [10%] vs six [3%]) and diarrhoea (43 [9%] vs 10 [4%]) On-treatment adverse event-related deaths were reported in 17 (4%) patients in the everolimus group and none in the placebo group. INTERPRETATION: Although progression-free survival was not significantly different between groups in the full analysis population, the 7·2 months prolongation we noted with the addition of everolimus in the HR-negative, HER2-positive population warrants further investigation, even if it did not meet prespecified criteria for significance. The safety profile was generally consistent with what was previously reported in BOLERO-3. Proactive monitoring and early management of adverse events in patients given everolimus and chemotherapy is crucial. FUNDING: Novartis Pharmaceuticals.

RESUMO

BACKGROUND: Platinum chemotherapy has a role in the treatment of metastatic triple-negative breast cancer but its full potential has probably not yet been reached. We assessed whether a cisplatin plus gemcitabine regimen was non-inferior to or superior to paclitaxel plus gemcitabine as first-line therapy for patients with metastatic triple-negative breast cancer. METHODS: For this open-label, randomised, phase 3, hybrid-designed trial undertaken at 12 institutions or hospitals in China, we included Chinese patients aged 18-70 years with previously untreated, histologically confirmed metastatic triple-negative breast cancer, and an ECOG performance status of 0-1. These patients were randomly assigned (1:1) to receive either cisplatin plus gemcitabine (cisplatin 75 mg/m(2) on day 1 and gemcitabine 1250 mg/m(2) on days 1 and 8) or paclitaxel plus gemcitabine (paclitaxel 175 mg/m(2) on day 1 and gemcitabine 1250 mg/m(2) on days 1 and 8) given intravenously every 3 weeks for a maximum of eight cycles. Randomisation was done centrally via an interactive web response system using block randomisation with a size of eight, with no stratification factors. Patients and investigator were aware of group assignments. The primary endpoint was progression-free survival and analyses were based on all patients who received at least one dose of assigned treatment. The margin used to establish non-inferiority was 1·2. If non-inferiority of cisplatin plus gemcitabine compared with paclitaxel plus gemcitabine was achieved, we would then test for superiority. The trial is registered with ClinicalTrials.gov, number NCT01287624. FINDINGS: From Jan 14, 2011, to Nov 14, 2013, 240 patients were assessed for eligibility and randomly assigned to treatment (120 in the cisplatin plus gemcitabine group and 120 in the paclitaxel plus gemcitabine group). 236 patients received at least one dose of assigned chemotherapy and were included in the modified intention-to-treat analysis (118 per group). After a median follow-up of 16·3 months (IQR 14·4-26·8) in the cisplatin plus gemcitabine group and 15·9 months (10·7-25·4) in the paclitaxel plus gemcitabine group, the hazard ratio for progression-free survival was 0·692 (95% CI 0·523-0·915; pnon-inferiority<0·0001, psuperiority=0·009, thus cisplatin plus gemcitabine was both non-inferior to and superior to paclitaxel plus gemcitabine. Median progression-free survival was 7·73 months (95% CI 6·16-9·30) in the cisplatin plus gemcitabine group and 6·47 months (5·76-7·18) in the paclitaxel plus gemcitabine group. Grade 3 or 4 adverse events that differed significantly between the two groups included nausea (eight [7%] vs one [<1%]), vomiting (13 [11%] vs one [<1%]), musculoskeletal pain (none vs ten [8%]), anaemia (39 [33%] vs six [5%]), and thrombocytopenia (38 [32%] vs three [3%]), for the cisplatin plus gemcitabine compared with the paclitaxel plus gemcitabine groups, respectively. In addition, patients in the cisplatin plus gemcitabine group had significantly fewer events of grade 1-4 alopecia (12 [10%] vs 42 [36%]) and peripheral neuropathy (27 [23%] vs 60 [51%]), but more grade 1-4 anorexia (33 [28%] vs 10 [8%]), constipation (29 [25%] vs 11 [9%]), hypomagnesaemia (27 [23%] vs five [4%]), and hypokalaemia (10 [8%] vs two [2%]). Serious drug-related adverse events were seen in three patients in the paclitaxel plus gemcitabine group (interstitial pneumonia, anaphylaxis, and severe neutropenia) and four in the cisplatin plus gemcitabine group (pathological bone fracture, thrombocytopenia with subcutaneous haemorrhage, severe anaemia, and cardiogenic syncope). There were no treatment-related deaths. INTERPRETATION: Cisplatin plus gemcitabine could be an alternative or even the preferred first-line chemotherapy strategy for patients with metastatic triple-negative breast cancer.

RESUMO

The local recurrence rate of phyllodes tumors of the breast varies widely among different subtypes, and distant metastasis is associated with poor survival. This study aimed to identify factors that are predictive of local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), and overall survival (OS) in patients with phyllodes tumors of the breast. Clinical data of all patients with a phyllodes tumor of the breast (n = 192) treated at Sun Yat-sen University Cancer Center between March 1997 and December 2012 were reviewed. The Pearson Χ² test was used to investigate the relationship between clinical features of patients and histotypes of tumors. Univariate and multivariate Cox regression analyses were performed to identify factors that are predictive of LRFS, DMFS, and OS. In total, 31 (16.1%) patients developed local recurrence, and 12 (6.3%) developed distant metastasis. For the patients who developed local recurrence, the median age at the diagnosis of primary tumor was 33 years (range, 17-56 years), and the median size of primary tumor was 6.0 cm (range, 0.8-18 cm). For patients who developed distant metastasis, the median age at the diagnosis of primary tumor was 46 years (range, 24-68 years), and the median size of primary tumor was 5.0 cm (range, 0.8-18 cm). In univariate analysis, age, size, hemorrhage, and margin status were found to be predictive factors for LRFS (P = 0.009, 0.024, 0.004, and 0.001, respectively), whereas histotype, epithelial hyperplasia, margin status, and local recurrence were predictors of DMFS (P = 0.001, 0.007, 0.007, and < 0.001, respectively). In multivariate analysis, independent prognostic factors for LRFS included age [hazard ratio (HR) = 3.045, P = 0.005], tumor size (HR = 2.668, P = 0.013), histotype (HR = 1.715, P = 0.017), and margin status (HR = 4.530, P< 0.001). Histotype (DMFS: HR = 4.409, P = 0.002; OS: HR = 4.194, P = 0.003) and margin status (DMFS: HR = 2.581, P = 0.013; OS: HR = 2.507, P = 0.020) were independent predictors of both DMFS and OS. In this cohort, younger age, a larger tumor size, a higher tumor grade, and positive margins were associated with lower rates of LRFS. Histotype and margin status were found to be independent predictors of DMFS and OS.

RESUMO

Background: Our aim was to evaluate the efficacy and safety of inetetamab plus chemotherapy in the first-line treatment of HER2-positive metastatic breast cancer. Methods: A HOPES study was conducted on patients with HER2-positive metastatic breast cancer. Eligible patients were randomly divided into test group and control group at a 2:1 ratio. Among them, patients in test group received inetetamab plus vinorelbine. Concurrently, patients in the control group received vinorelbine. During the trial, safety evaluation was conducted every 4 weeks and efficacy evaluation was conducted every 8 weeks. As assessed by the Response Criteria Evaluation in Solid Tumors (RECIST) 1.0 criteria, the primary endpoint was progression-free survival (PFS) and the secondary endpoints included objective response rate (ORR) and disease control rate (DCR). Safety was estimated according to the National Cancer Institute Common Toxicity Criteria (NCI-CTC) version 2.0. Efficacy and safety of the postoperative recurrent-metastases first-line subgroup in the HOPES registry study of inetetamab was analyzed and compared with previous clinical studies of trastuzumab in the first-line treatment of HER2-positive metastatic breast cancer. Results: In total, we included 315 patients. Among them, 114 patients in the postoperative recurrent-metastases first-line subgroup were assigned to the full analysis set (FAS) (test group, 72; and control group, 42). The test group significantly prolonged median PFS (mPFS) (11.1 vs. 3.3 months of the control group; P<0.0001). ORR and DCR were remarkably higher than the control group (ORR, 61.5% vs. 29.7% with an increase of 31.8%, P=0.0224; DCR, 93.8% vs. 59.4% with an increase of 34.4%, P=0.0003). Efficacy and safety of postoperative recurrent-metastases first-line subgroup in the HOPES study was comparable to previous clinical studies of trastuzumab as first-line treatment of HER2-positive metastatic breast cancer. Conclusions: Inetetamab has shown efficacy and safety equivalent to trastuzumab for patients in the first-line treatment of postoperative recurrence-metastases HER2-positive breast cancer, which confirms its important status and potential as first-line treatment. Inetetamab provides more first-line targeted therapy options for patients with HER2-positive metastatic breast cancer.

RESUMO

Overexpression of human epidermal growth factor receptor-2 (HER2) in metastatic breast cancer (MBC) is associated with poor prognosis. This single-arm open-label trial (EGF109491; NCT00508274) was designed to confirm the efficacy and safety of lapatinib in combination with capecitabine in 52 heavily pretreated Chinese patients with HER2-positive MBC. The primary endpoint was clinical benefit rate (CBR). Secondary endpoints included progression-free survival (PFS), time to response (TTR), duration of response (DoR), central nervous system (CNS) as first site of relapse, and safety. The results showed that there were 23 patients with partial responses and 7 patients with stable disease, resulting in a CBR of 57.7%. The median PFS was 6.34 months (95% confidence interval, 4.93-9.82 months). The median TTR and DoR were 4.07 months (range, 0.03-14.78 months) and 6.93 months (range, 1.45-9.72 months), respectively. Thirteen (25.0%) patients had new lesions as disease progression. Among them, 2 (3.8%) patients had CNS disease reported as the first relapse. The most common toxicities were palmar-plantar erythrodysesthesia (59.6%), diarrhea (48.1%), rash (48.1%), hyperbilirubinemia (34.6%), and fatigue (30.8%). Exploratory analyses of oncogenic mutations of PIK3CA suggested that of 38 patients providing a tumor sample, baseline PIK3CA mutation status was not associated with CBR (P = 0.639) or PFS (P = 0.989). These data confirm that the lapatinib plus capecitabine combination is an effective and well-tolerated treatment option for Chinese women with heavily pretreated MBC, irrespective of PIK3CA status.

RESUMO

BACKGROUND AND OBJECTIVE: The brain is one of the most common metastatic sites of breast cancer. Brain metastases develop in 10%-15% of patients with breast cancer and are associated with poor prognosis. The purpose of this retrospective study was to analyze the clinical characteristics and survival of patients with brain metastases due to breast cancer of different subtypes and to identify the prognostic factors that affect clinical outcome. METHODS: A total of 89 patients with breast cancer brain metastases diagnosed between October 1997 and July 2008 at Sun Yat-sen University Cancer Center were included in this study. Among the 89 patients, the number of luminal A, luminal B, human epidermal growth factor receptor 2 (HER-2), and triple-negative (TN) subtypes were 30, 20, 16, and 14, respectively; 9 patients had an unknown subtype. The clinical characteristics, pathologic features, and prognostic factors were analyzed both at the initial diagnosis and at the diagnosis of brain metastases. Endocrine therapy for patients with luminal subtypes was further studied. RESULTS: The median age of patients was 46 years (range 28-74 years). The median survival time was 8.0 months (range, 0-80 months), the 1-year survival rate was 32% and the 5-year survival rate was 4%. The time to brain metastasis differed according to clinical stage at the initial diagnosis, and the time for patients with the luminal A subtype was the longest (P < 0.001). Multivariate analysis demonstrated that performance status score > 1, multiple brain metastases and without whole brain radiotherapy (WBRT) in combination with chemotherapy were associated with poor prognosis. Compared with the luminal A subtype, features of the HER-2 and TN subtypes included early metastases, rapid progression after first-line treatment (8.0 months vs. 11.0 months), and poor overall survival (25.0 months vs. 63.0 months). The luminal A subtype showed a tendency for good prognosis and slow growth. Tamoxifen could improve the survival of luminal A/B subtypes (median survival 24.0 months vs. 7.0 months, respectively, P = 0.002). CONCLUSIONS: The prognosis of brain metastases from breast cancer was poor, especially in patients with HER-2 and TN subtypes. Generally, WBRT in combination with chemotherapy was the standard treatment modality. Patients with the luminal subtypes could benefit from tamoxifen.

RESUMO

BACKGROUND: The overall survival (OS) among patients with advanced breast cancer (ABC) varies greatly. Although molecular subtype is known as the most important factor in OS differentiation, significant differences in OS among patients with the same molecular subtype still occur, leading to the need for a more accurate prognostic prediction model. This study aimed to develop a prediction model (nomogram) based on current diagnosis and treatment to predict the OS of newly diagnosed ABC patients in China. METHODS: From the institution's database, we collected data of 368 ABC patients from Sun Yat-sen Memorial Hospital (national hospital) as a training set to establish a nomogram with prognostic risk factors that calculated the predicted probability of survival. Nomograms were independently validated with 278 patients with ABC from two other institutions using the concordance index (C-index), calibration plots and risk group stratifications. RESULTS: The initial primary tumor stage, molecular subtype, disease-free survival (DFS), presence of brain metastasis, and the tumor burden of metastasis disease (local recurrence, oligo-metastatic disease, or multiple-metastatic disease) were included in the prognostic nomogram. The nomogram had a C-index of 0.77 and 0.71 in the training and the validation sets, respectively. The nomogram was able to stratify patients into different risk groups, respectively (HR 6.81, 95% CI: 4.69 to 9.89, P<0.001). In the lower risk score group (risk score <11), there was no significant difference between the OS with chemotherapy and hormone therapy (HR 0.81, 95% CI: 0.44 to 1.47, P=0.48). CONCLUSIONS: We have constructed a novel prediction nomogram that can guide the physicians to select personalized treatment options. Furthermore, our study is the first to add oligo-metastatic disease and primary endocrine/trastuzumab resistance into the prognostic models.

RESUMO

OBJECTIVE: This study was designed to evaluate the efficacy and toxicity of modified BFM-90 regimen originated from Germany authors in the treatment of Chinese childhood and adolescent lymphoblastic lymphoma. METHODS: Thirty-six untreated lymphoblastic lymphoma patients aged from 3 to 18 years were included, with 1 patient in stage II , 9 in stage III and 26 in stage IV. Of these 36 patients, 28 (77.7%) were diagnosed as T cell phenotype, 26 (72. 2%) were found to have mediastinal mass, 21 (58. 3%) had bone marrow involvement. All patients received chemotherapy of modified BFM-90 regimen consisting of induction remission, central nerve system prophylaxis, re-induction remission and maintenance therapy. Total treatment duration was two years. The difference from standard BFM-90 is that we omitted cranial radiotherapy but gave regular high dose methotrexate (MTX) iv infusion and intrathecal MTX therapy during maintenance therapy period. Kaplan-Meier method was used to evaluate survival rate. RESULTS: Of 36 patients, 32 (88%) achieved complete remission (CR) , 1 (2. 7%) partial remission (PR) with an overall response rate of 90.7%. One patient had disease progression ( DP). Two patients received autologous stem cell transplantation at CR1, and two patients received radiotherapy to mediastinum. Totally, 5 patients relapsed, while 2 of them were still alive after salvage chemotherapy. The other 3 died of tumor progression. Two patients died during induction remission, 1 of fungal septicemia, the other of cerebral hemorrhage; one PR and one DP patient died of disease, therefore, totally 7 patients died at last. Median follow-up time was 28 months. Overall three-year survival rate was 78. 3%. The major toxicity was myelosuppression. CONCLUSION: Modified BFM-90 protocol can improve the efficacy and survival of Chinese childhood and adolescent lymphoblastic lymphoma with tolerable toxicity. However, this modified protocol should only be used in experienced cancer center or hematological unit.

RESUMO

OBJECTIVE: T-cell non-Hodgkin lymphoma was heterogeneous and relatively high incident in our country. It's response and prognosis were poor. This study was to analyze clinical feature and survival of T-NHL. METHODS: Records of 103 cases with T-NHL, treated from Dec 1998 to Dec 2004 in Cancer Center of Sun Yat-sen University, were retrospectively analyzed. All the patients were classified according to WHO 2001 Classification Criteria. RESULTS: Median age of the whole group was 35 (ranged 2-78) years-old. Of the 103 cases, 68 were male, 35 were female; 25 (24.3%) received chemoradiotherapy, 70 (68.0%) received chemotherapy alone, 3 received radiotherapy and 5 received stem cell transplantation after complete remission. Median survival was 24.1 (ranged 0.8-84) months. 5-year survival rate was 24.3%. Kaplan-Meier analysis discovered that age > 60 years, advanced stage (stage II, IV), extranodal involvement, bulky disease, B symptom, performance status (PS) > or = 2, LDH elevated, hypoalbumin, median-high IPI (IPI > or = 2) were bad to prognosis, but Cox regression found that age > or = 60 years, performance status (PS) > or = 2S, hypoalbumin were the independent bad factors to prognosis. CONCLUSION: This study proved that age, albumin, PS were the independent factors to prognosis.

RESUMO

Trastuzumab is the backbone of HER2-positive early breast cancer (eBC) and metastatic breast cancer (mBC) treatment, but limited data exist as to re-treatment in relapsed patients. In this prospective, single arm, multicenter trial, we assessed efficacy and safety of trastuzumab and taxane combination in Chinese patients with HER2-positive mBC relapsed after prior (neo)adjuvant trastuzumab. Patients with previous (neo)adjuvant trastuzumab treatment for≥9 weeks and a relapse-free interval ≥6 months were assigned to trastuzumab treatment with paclitaxel or docetaxel. The primary endpoint was progression free survival (PFS). Secondary endpoints included overall response rate (ORR), clinical benefit rate (CBR), duration of response (DOR), time to progression (TTP), overall survival (OS) and safety profile. Thirty-two patients were enrolled and treated for a median duration of 33.5 weeks. The median PFS was 9.9 months (95% CI, 6.28 - 13.63 months). The ORR was 81.3% (95% CI, 63.6% - 92.8%) and CBR (CR+PR+SD≥6months) was 81.3% (95% CI, 63.6% - 92.8%). The median DOR was 9.8 months (95% CI, 5.82 - 11.60 months) and median TTP was 9.9 months (95% CI, 6.28-13.63 months). OS median follow-up time was 20.1 months and 25% OS time was 25.5 months. The safety profile was acceptable with common adverse events including leukopenia (59.4%), neutropenia (56.3%), hypoaesthesia (34.4%) and granulocytopenia (31.3%). In conclusion, re-treatment with trastuzumab plus a taxane as first-line therapy is an effective regimen for patients with HER2-positive mBC relapsed after (neo)adjuvant trastuzumab. The safety profile was good and the adverse reactions were tolerable and manageable.

RESUMO

INTRODUCTION: The aim of the study was to analyze clinicopathologic characteristics and survival and to identify prognostic factors for Chinese patients with HER2-positive metastatic breast cancer. MATERIAL AND METHODS: A total of 243 patients with HER2-positive metastatic breast cancer, treated during the period 2002 to 2009, were followed up from initial disease diagnosis to death or date of last follow-up (December 2011). Cumulative survival curves were created using Kaplan-Meier analysis with the log-rank test. Prognostic factors were analyzed by univariate and multivariate Cox proportional hazards regression analysis. RESULTS: During follow-up, 205 patients died, with a median OS of 27 months (95% CI: 23.5, 30.5 months), and the 1-, 3-, and 5-year survival rates were 84.4%, 38.6%, and 18.1%, respectively. The median OS of HR+ patients was significantly higher than that of HR- patients (p < 0.001). Surgery (hazard ratio = 0.60, p = 0.002), endocrine therapy (hazard ratio = 0.53, p < 0.01), and anti-HER2 therapy (hazard ratio = 0.63, p = 0.003) were favorable independent prognostic factors for patients with HER2-positive metastatic breast cancer. CONCLUSIONS: These results indicated that surgical intervention, endocrine therapy, and anti-HER2 therapy were good for these HER2 positive patients with metastatic breast cancer, but ECOG performance status < 1 and metastasis to brain were unfavorable independent prognostic factors. HR status was not an independent prognostic factor.

RESUMO

The recently available guidelines on the management of advanced breast cancer (ABC) organized by Chinese Anti-Cancer Association, Committee of Breast Cancer Society (CACA-CBCS) do not elucidate ABC in details. To instruct clinicians in treatment of ABC, a Chinese expert consensus meeting on diagnosis and treatment of ABC was held in June 2014 and a consensus is developed. The following consensus provides the level of evidence and supporting documents for each recommendation, and introduces research topics to be urgently addressed. Notably, the consensus on diagnosis and treatment of ABC in China is developed to be applied nationwide. In different areas, multidisciplinary treatment (MDT) tailored to the each patient and the disease itself should be applied based on the basic principles of modern oncology.

RESUMO

OBJECTIVE: To evaluate the efficacy and safety of capecitabine as first-line therapy in patients with advanced and recurrent colorectal cancer. METHODS: From December 2000 to November 2001, sixty patients with advanced and recurrent colorectal cancer received first-line capecitabine treatment given at a dose of 1250 mg/m(2) twice daily, on days 1 - 14 every 21 days. At least 2 cycles were administered. RESULTS: The overall response rate was 23.3% with 14 PR, 24 SD (40.0%) and 15 PD. The median survival time was 14.7 months. The survival rate was 63.9% at 12-months and 33.4% at 24-months. Grade III-IV adverse effects were diarrhea in 4 patients (6.6%), anemia in 2 (3.3%) and hand-foot syndrome (HFS) in 1 (1.7%); Grade I-II adverse effects were hyperpigmentation in 20 (33.3%), HFS in 18 (30.0%) and diarrhea in 10 (16.7%). CONCLUSION: Capecitabine is an efficacious and better-tolerated alternative treatment for the patients with advanced and recurrent colorectal cancer.

RESUMO

PURPOSE: The efficacy of trastuzumab in Chinese breast cancer (BC) patients has rarely been reported. This study was designed to compare the clinical outcomes of HER2-positive BC patients receiving or not receiving trastuzumab treatment and HER2-negative BC patients. PATIENTS AND METHODS: This study involved three groups of patients. The first group was 115 human epidermal growth factor receptor 2 (HER2)-positive BC patients treated with trastuzumab who were enrolled at Sun Yat-sen University Cancer Center between January 2002 and July 2010; the second group was a matched control group of 115 HER2-positive patients who did not receive trastuzumab treatment; the third group was a matched group of 115 HER2-negative patients who received conventional therapy in the adjuvant setting. The primary endpoint was 3-year and 5-year disease-free survival (3-DFS and 5-DFS, respectively). The Kaplan-Meier method, log-rank test, and multivariate Cox proportional hazard regression model were used for survival analysis. The differences in survival rates among the three groups were also analyzed according to two different periods: 2002-2006 and 2007-2010. RESULTS: The median duration of follow-up was 36 months (range, 12-111 months). The 3-DFS rates in the HER2-negative group, the HER2-positive group who received trastuzumab treatment, and the HER2-positive group who did not receive trastuzumab treatment were 82.6%, 89.6%, and 67.0%, respectively. The 3-DFS rate for the total study population was statistically significant (P < 0.001). Further analysis indicated a statistically significant difference in 3-DFS between either of the first two groups and the third group (P < 0.01), but the difference between the first two groups was not statistically significant (P = 0.157). Among the three groups, the 3-DFS rates during 2002-2006 did not have a significant difference compared with that during 2007-2010. CONCLUSION: This study has further confirmed the efficacy of trastuzumab for HER2-positive operable BC in Chinese patients. It has also demonstrated that the 3-DFS and 5-DFS rates between HER2-positive patients receiving trastuzumab treatment and HER2-negative patients are comparable.

RESUMO

Trastuzumab has been the standard treatment in first-line treatment of HER-2-positive advanced breast cancer (H2ABC). This study explored whether the delayed and repeated use of trastuzumab could influence overall survival (OS). A total of 128 patients with H2ABC who had received at least one line of trastuzumab-based regimens were included. The primary endpoint was OS defined as from the date of first diagnosis of H2ABC to death. The median OS of initiating trastuzumab in first-line group (n = 56), in the second-line group (n = 32), and the third- or more-line group (n = 40) was 40.6 m, 39.5 m, and 38 m, respectively (P = 0.867). For patients who had received over one line of trastuzumab (n = 46), the median OS was 44 m, and for those receiving only one line (n = 67), it was 27.6 m (P = 0.059). The delayed use of trastuzumab has no negative effect on the OS of patients with H2ABC. There is a trend of improved OS over the repeated use of trastuzumab.

RESUMO

PURPOSE: The clinical significance of bilateral breast cancer is unclear and its influence on prognosis is controversial. We compared the characteristics and prognosis of bilateral breast cancer and unilateral breast cancer. METHODS: Our study included 4,183 patients with breast cancer who were treated at Sun Yat-sen University Cancer Center between January 1, 2000, and December 31, 2007. Bilateral breast cancer was categorized as synchronous (within 3 months) or metachronous (diagnosed after 3 months of first cancer). SPSS was used for data analysis. RESULTS: 106 (2.5%) and 31 (0.7%) patients were diagnosed with metachronous and synchronous bilateral cancer. Women with bilateral cancer had more frequent postmenopause, HER-2 negativity, and advanced disease than in patients with unilateral cancer. Young age at diagnosis, invasive lobular carcinoma, ER/PR negativity, HER-2 positivity, radiation, large tumor size (T > 5 cm), and stage III disease of the first cancer were risk factors for contralateral cancer. The 5-year disease-free survival and overall survival rates were 76 and 83% for unilateral cancer, while 32 and 72% for bilateral cancer (P = 0.000 for both). CONCLUSIONS: Bilateral cancer was associated with shorter disease-free survival and overall survival than unilateral cancer. The prognosis of metachronous bilateral cancer, especially those diagnosed within 2 years after the first cancer was significantly worse than synchronous bilateral cancer.

RESUMO

OBJECTIVE: To study the biological and clinicopathological characteristics of neuroendocrine tumors of the kidney (KNETs) for improving the diagnosis and treatment of this diseases. METHODS: The pathological and clinical features of 3 KNET cases treated in Sun Yat-sen University Cancer Center between 1999 and 2010 were summarized, and the the histogenesis, pathological and immunohistochemical characteristics, diagnosis and prognosis of KNETs were analyzed with review of all reported cases worldwide. RESULTS: All the 3 patients had waist masses but without clinical manifestations of carcinoid syndrome, and underwent resection of the tumors. The postoperative pathological diagnosis was carcinoid carcinoma in 2 patients and Wilms tumor with neuroendocrine differentiation in 1 patient. Immunohistochemical examination showed that the tumors were positively stained for cytokeratin and vimentin; positivity for neuron-specific enolase and synaptophysin was found in 2 cases, and chromogranin positivity in 1 case. After the operation, 1 patient received chemotherapy, 1 had biotherapy and radiotherapy, and 1 received no further treatment. During the follow-up from 6 months to 6 years, 1 patient died of tumor metastasis, 1 was lost to follow-up, and 1 showed no recurrence until now. CONCLUSIONS: KNETs has specific pathological characteristics. Abdominal masses, acute loin pain and hematuria are the most common symptoms. A definite diagnosis relies on pathology and immunohistochemistry. For early carcinoid carcinoma, surgical resection is curable, but in advanced cases, the prognosis is poor and comprehensive therapy is recommended.
