BackgroundThe addition of HER2-targeted agents to standard treatment has been shown to improve outcomes for HER2 positive metastatic breast cancer patients. We undertook a meta-analysis to evaluate the efficacy of HER2-targeted therapy in addition to standard treatment in metastatic breast cancer patients.Patients and methodsEligible trials were randomised controlled trials (RCTs) comparing the addition of HER2 therapy to standard treatment (hormone or chemotherapy) reporting overall survival (OS), time to progression (TTP), progression-free survival (PFS) and/or response rates.ResultsEight trials comprising 1848 patients were eligible for inclusion. HER2-targeted agents were trastuzumab and lapatinib and therapeutic partners were taxanes (4 RCTs), anthracyclines (1), capecitabine (2), anastrozole (1) and letrozole (1). The addition of HER2-targeted agents improved OS [hazard ratios (HR) 0.78; 95% confidence interval (CI) 0.67–0.91], TTP (HR 0.56; 95% CI 0.48–0.64), PFS (HR 0.63; 95% CI 0.53–0.74) and overall response rate (relative risk 1.67; 95% CI 1.46–1.90).ConclusionsOur meta-analysis confirms the benefit of adding HER2-targeted therapy to standard treatment in HER2 positive metastatic breast cancer. Compared with OS, TTP, PFS and ORR overestimate treatment benefit. Trials in our meta-analysis differed in terms of partner drug or HER2 agents, yet delivered comparable outcomes.  相似文献

BackgroundBevacizumab has consistently demonstrated improved progression-free survival (PFS) and response rate when combined with first-line chemotherapy for HER2-negative metastatic breast cancer (mBC). However, the lack of a significant overall survival (OS) difference continues to attract debate, and identification of patients deriving greatest benefit from bevacizumab remains elusive.Patients and methodsIndividual patient data from three randomised phase III trials in the first-line HER2-negative mBC setting were analysed, focusing specifically on efficacy in poor-prognosis patients.ResultsThe meta-analysis (n = 2447) demonstrated a PFS hazard ratio (HR) of 0.64 (95% confidence interval [CI] 0.57–0.71; median 9.2 months with bevacizumab versus 6.7 months with non-bevacizumab therapy) and response rate of 49% versus 32%, respectively. The OS HR was 0.97 (95% CI 0.86–1.08); median 26.7 versus 26.4 months, respectively. In patients with triple-negative mBC, the HRs for PFS and OS were 0.63 (95% CI 0.52–0.76) and 0.96 (95% CI 0.79–1.16), respectively. Median PFS was 8.1 months with bevacizumab versus 5.4 months with chemotherapy alone, median OS was 18.9 versus 17.5 months, respectively, and 1-year OS rates were 71% versus 65%.ConclusionsBevacizumab improves efficacy, including 1-year OS rates, both overall and in subgroups of poor-prognosis patients with limited treatment options.  相似文献

Although both bevacizumab and paclitaxel significantly improve the efficacy of chemotherapy for human epidermal growth factor receptor 2 (HER2)-negative patients with metastatic breast cancer (MBC), little have changed with overall survival rates when they have been used alone or combined with other chemotherapy. Thus, a meta-analysis was conducted to evaluate the efficacy of bevacizumab combined with paclitaxel in HER2-negative MBC patients. Pubmed and Embase were systematically reviewed for studies published up to September 2013 in which bevacizumab plus paclitaxel were compared with other chemotherapy. Primary outcomes comprised overall survival (OS), progression-free survival (PFS), and objective response rate (ORR). Eight phase II/III clinical trials met the inclusion criteria, with a total of 3,758 patients. The pooled results showed that combination of bevacizumab and paclitaxel significantly improved the PFS (HR?=?0.63, 95 % CI, 0.55–0.73, P?=?0.011), ORR (RR?=?1.28, 95 % CI, 0.96–1.70, P?=?0.0), but had no effect on OS (HR?=?0.91, 95 % CI, 0.81–1.01, P?=?0.855). The meta-analysis confirms the benefits of bevacizumab–paclitaxel combination therapy in HER2 negative metastatic breast cancer, with an improvement in both progression free survival and objective response rate. However, no significant OS benefit was observed.  相似文献

BackgroundBevacizumab combined with paclitaxel as first-line chemotherapy for patients with HER2-negative metastatic breast cancer (MBC) has led to mixed results in randomized trials, with an improvement in progression-free survival (PFS) but no statistically significant overall survival (OS) benefit. Real-life data could help in assessing the value of this combination.Patients and methodsThis study aimed to describe the outcome following first-line paclitaxel with or without bevacizumab in the French Epidemiological Strategy and Medical Economics (ESME) database of MBC patients, established in 2014 by Unicancer. The primary and secondary end points were OS and PFS, respectively.ResultsFrom 2008 to 2013, 14 014 MBC patient files were identified, including 10 605 patients with a HER2-negative status. Of these, 3426 received paclitaxel and bevacizumab (2127) or paclitaxel (1299) as first-line chemotherapy. OS adjusted for major prognostic factors was significantly longer in the paclitaxel and bevacizumab group compared with paclitaxel [hazard ratio (HR) 0.672, 95% confidence interval (CI) 0.601–0.752; median survival time 27.7 versus 19.8 months]. Results were consistent in all supportive analyses (using a propensity score for adjustment and as a matching factor for nested case–control analyses) and sensitivity analyses. Similar results were observed for the adjusted PFS, favoring the combination (HR 0.739, 95% CI 0.672–0.813; 8.1 versus 6.4 months).ConclusionsIn this large-scale, real-life setting, patients with HER2-negative MBC who received paclitaxel plus bevacizumab as first-line chemotherapy had a significantly better OS and PFS than those receiving paclitaxel. Despite robust methodology, real-life data are exposed to important potential biases, and therefore, results need to be treated with caution. Our data cannot therefore support extension of current use of bevacizumab in MBC.  相似文献

BackgroundExcept for meeting the individual palliative need, the benefit of breast surgery in primary metastatic breast cancer (PMBC), also known as de novo metastatic breast cancer, on long-term outcomes remains controversial. Twenty-four hundred and one patients with metastatic breast cancer, enrolled between 2000 and 2011 in two prospective non-interventional studies on targeted therapy, were screened with respect to this question.MethodsOne study investigated trastuzumab therapy for human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer in addition to mainly first-line chemotherapy. The other observed bevacizumab added to chemotherapy as first-line treatment for mostly HER2-negative disease.ResultsFive-hundred and seventy (24%) patients presented with PMBC, and valid information on resection of the primary tumour was available for 568 women. Out of these, 426 (75%) underwent local resection. The latter group was characterised by less overall metastatic burden and a lower proportion of T4 tumours. No major differences were observed with respect to age, hormone receptor and HER2 status, visceral disease and performance status. Numerically, the surgery group showed a slightly favourable progression-free survival (PFS, medians: 13.6 versus 11.8 months; P = 0.18) and overall survival (OS, 34.1 versus 31.7; P = 0.23). However, in multivariable analysis, including all other univariably significant parameters, no trend for better outcome after surgery remained detectable, neither for PFS (hazard ratio 0.99; P = 0.92) nor for OS (0.95; P = 0.71).ConclusionsOur findings suggest no major survival benefit for local resection in the overall PMBC population treated with modern targeted therapies. However, further analyses are warranted to define specific risk groups, which may benefit from surgical removal of the primary.  相似文献

BackgroundThe randomised phase III TANIA trial demonstrated that continuing bevacizumab with second-line chemotherapy for locally recurrent/metastatic breast cancer (LR/mBC) after progression on first-line bevacizumab-containing therapy significantly improved progression-free survival (PFS) compared with chemotherapy alone [hazard ratio (HR) = 0.75, 95% confidence interval (CI) 0.61–0.93]. We report final results from the TANIA trial, including overall survival (OS) and health-related quality of life (HRQoL).Patients and methodsPatients with HER2-negative LR/mBC that had progressed on or after first-line bevacizumab plus chemotherapy were randomised to receive standard second-line chemotherapy either alone or with bevacizumab. At second progression, patients initially randomised to bevacizumab continued bevacizumab with their third-line chemotherapy, but those randomised to chemotherapy alone were not allowed to cross over to receive third-line bevacizumab. The primary end point was second-line PFS; secondary end points included third-line PFS, combined second- and third-line PFS, OS, HRQoL and safety.ResultsOf the 494 patients randomised, 483 received second-line therapy; 234 patients (47% of the randomised population) continued to third-line study treatment. The median duration of follow-up at the final analysis was 32.1 months in the chemotherapy-alone arm and 30.9 months in the bevacizumab plus chemotherapy arm. There was no statistically significant difference between treatment arms in third-line PFS (HR = 0.79, 95% CI 0.59–1.06), combined second- and third-line PFS (HR = 0.85, 95% CI 0.68–1.05) or OS (HR = 0.96, 95% CI 0.76–1.21). Third-line safety results showed increased incidences of proteinuria and hypertension with bevacizumab, consistent with safety results for the second-line treatment phase. No differences in HRQoL were detected.ConclusionsIn this trial, continuing bevacizumab beyond first and second progression of LR/mBC improved second-line PFS, but no improvement in longer term efficacy was observed. The second-line PFS benefit appears to be achieved without detrimentally affecting quality of life.ClinicalTrials.govNCT01250379.  相似文献

Background.

Limited data are available describing the natural history of patients with HER2-positive and hormone receptor (HR)-positive metastatic breast cancer (MBC). We examined first-line treatment patterns and clinical outcomes in patients with HER2-positive, HR-positive MBC in a real-world setting.

Methods.

registHER is a prospective, observational cohort of 1,023 patients with HER2-positive MBC diagnosed within 6 months of enrollment and followed until death, disenrollment, or June 2009 (median follow-up time: 27 months). Demographics, first-line treatment patterns, and clinical outcomes were examined for 530 HER2-positive, HR-positive patients. Progression-free survival (PFS) and overall survival (OS) times were examined. Multivariate analyses adjusted for baseline demographic and prognostic factors.

Results.

HER2-positive, HR-positive patients receiving first-line trastuzumab plus hormonal therapy had significantly longer PFS times than patients who received hormonal therapy only (13.8 vs. 4.8 months; adjusted hazard ratio [HR]: 0.37, 95% confidence interval [CI]: 0.22–0.60); a nonsignificant reduction in OS time was observed (adjusted HR: 0.55, 95% CI: 0.27–1.14). Compared with patients who received first-line trastuzumab plus chemotherapy, patients who received first-line trastuzumab plus chemotherapy and hormonal therapy had longer median PFS times (20.4 months vs. 9.5 months; adjusted HR: 0.53, 95% CI: 0.42–0.68); a statistically significant reduction in risk of death was observed (adjusted HR: 0.50, 95% CI: 0.36–0.70). Sequential use of chemotherapy and hormonal therapy was associated with improved OS times when compared with concurrent use (adjusted PFS HR: 0.81, 95% CI: 0.54–1.21; adjusted OS HR: 0.48, 95% CI: 0.26–0.89).

Conclusions.

These real-world data in patients with HER2-positive/HR-positive MBC provide evidence that, with or without chemotherapy, dual targeting of HRs and HER2 receptors is associated with significantly prolonged PFS and OS times.  相似文献

Adjuvant hormonal therapy for hormone receptor (HR)-positive primary breast cancer patients and a human epidermal growth factor receptor 2 (HER2)-targeted agent for HER2-positive primary breast cancer patients are standard treatment. However, it is not well known whether adding hormonal therapy to the combination of preoperative or postoperative chemotherapy and HER2-targeted agent contributes any additional clinical benefit in patients with HR-positive/HER2-positive primary breast cancer regardless of cross-talk between HR and HER2. We retrospectively reviewed records from 897 patients with HR-positive/HER2-positive primary breast cancer with clinical stage I–III disease who underwent surgery between 1988 and 2009. We determined the overall survival (OS) and disease-free survival (DFS) rates according to whether they received hormonal therapy or not and according to the type of hormonal therapy, tamoxifen and aromatase inhibitor, they received. The median followup time was 52.8 months (range 1–294.6 months). Patients who received hormonal therapy with chemotherapy and trastuzumab (n = 128) had significantly higher OS and DFS rates than did those who received only chemotherapy and trastuzumab (n = 46) in log-rank analysis (OS 96.1 vs. 87.0 %, p = 0.023, DFS 86.7 vs. 78.3 %, p = 0.029). There was no statistical difference in OS or DFS between those given an aromatase inhibitor and those given tamoxifen. In multivariate analysis, receiving hormonal therapy in addition to the combination of chemotherapy and trastuzumab was the sole independent prognostic factor for DFS (hazard ratio 0.446; 95 % CI 0.200–0.992; p = 0.048), and there was a similar trend in OS. Our study supported that hormonal therapy, whether in the form of an aromatase inhibitor or tamoxifen, confers a survival benefit when added to chemotherapy and trastuzumab in patients with HR-positive/HER2-positive primary breast cancer. Adjuvant treatment without hormonal therapy is inferior for this patient population.  相似文献

BackgroundHuman epidermal growth factor receptor 2–positive (HER2+) breast cancer is generally treated with HER2-targeted therapy combined with chemotherapy. Patients with HER2+ and estrogen receptor–positive (ER+) cancer are additionally treated with long-term hormone therapy. This study examined the metastatic pattern and prognosis of both ER+/HER2+ and ER?/HER2+ breast cancer.Patients and MethodsA total of 54,147 patients with HER2+ breast cancer from the National Cancer Data Base (NCDB, 2010-2013) and 31,946 patients with HER2+ breast cancer from the Surveillance, Epidemiology, and End Results Program (SEER, 2010-2014) were examined. Sites of metastasis and overall survival (OS) were examined in the NCDB, while OS and breast cancer–specific survival were examined in the SEER database.ResultsCompared to ER?/HER2+ breast cancer, ER+/HER2+ breast cancer was more likely to metastasize to bone but less likely to brain, liver, and lung and less likely to result in multiple metastases. In univariate analysis based on the NCDB, patients with ER?/HER2+ breast cancer had worse OS in all metastasis subsets, including patients who received HER2-targeted therapy. This poor survival for ER?/HER2+ persisted in patients with metastasis to bone and lung, and multiple metastases. In multivariate analysis adjusting for age, tumor grade, surgery, chemotherapy, HER2-targeted therapy, and hormone therapy, ER?/HER2+ patients with bone metastasis still had worse OS. In the SEER, ER?/HER2+ patients had both worse OS and breast cancer–specific survival in univariate analysis.ConclusionThis large study showed patients with ER+/HER2+ and ER?/HER2+ breast cancers had different metastatic patterns. Patients with ER?/HER2+ breast cancer may require more aggressive treatment.  相似文献

IntroductionThe role of surgery for breast cancer liver metastases (BCLM) remains controversial. This study aimed to analyze survival in patients treated with hepatectomy plus systemic therapy or systemic therapy alone for BCLM and to determine selection factors to guide surgical therapy.Materials and methodsPatients who underwent hepatectomy plus systemic therapy (n = 136) and systemic therapy alone for isolated BCLM (n = 763) were compared. Overall survival (OS) was analyzed after propensity score matching. Intrinsic subtypes were defined as: luminal A (estrogen receptor [ER]+ and/or progesterone receptor positive [PR]+, human epidermal growth factor receptor 2 [HER2]–), luminal B (ER and/or PR+, HER2+), HER2-enriched (ER and PR–, HER2+), and basal-like (ER, PR, HER2–).ResultsAfter hepatectomy, independent predictors of poor OS were number and size of liver metastases, and intrinsic subtype (hazard ratios, 1.11, 1.16, and 4.28, respectively). Median OS was 75 and 81 months among patients with luminal B and HER2-enriched subtypes, compared with 17 and 53 months among patients with basal-like and luminal A subtypes (P < .001). Median progression-free survival (PFS) was 60 months with the HER2-enriched subtype, compared with 17, 16, and 5 months with luminal A, luminal B, and basal-like subtypes, respectively (P < .001). After propensity score matching, 5-year OS rates were 56% vs. 40% in the surgery vs. systemic therapy alone groups (P = .018).ConclusionSurgical resection of BCLM yielded higher OS compared with systemic therapy alone and prolonged PFS among patients with the HER2-enriched subtype. These findings support the use of surgical therapy in appropriately selected patients, based on intrinsic subtypes.  相似文献

AimOligometastatic breast cancer (OMBC) is a disease-entity with potential for long-term remission in selected patients. Those with truly limited metastatic load (rather than occult widespread metastatic disease) may benefit from multimodality treatment including local ablative therapy of distant metastases. In this systematic review, we studied factors associated with long-term survival in patients with OMBC.MethodsEligible studies included patients with OMBC who received a combination of local and systemic therapy as multimodal approach and reported overall survival (OS) or progression-free survival (PFS), or both. The Quality in Prognosis Studies (QUIPS) tool was used to assess the quality of each included study. Independent prognostic factors for OS and/or PFS are summarized.ResultsOf 1271 screened abstracts, 317 papers were full-text screened and twenty studies were included. Eleven of twenty studies were classified as acceptable quality. Definition of OMBC varied between studies and mostly incorporated the number and/or location of metastases. The 5-year OS ranged between 30 and 79% and 5-year PFS ranged between 25 and 57%. Twelve studies evaluated prognostic factors for OS and/or PFS in multivariable models. A solitary metastasis, >24 months interval between primary tumor and OMBC, no or limited involved axillary lymph nodes at primary diagnosis, and hormone-receptor positivity were associated with better outcome. HER2-positivity was associated with worse outcome, but only few patients received anti-HER2 therapy.ConclusionsOMBC patients with a solitary distant metastasis and >24 months disease-free interval have the best OS and may be optimal candidates to consider a multidisciplinary approach.  相似文献

BackgroundA study was initiated at Roswell Park Comprehensive Cancer Center to capture the real-world experience related to the use of CDK4/6 inhibitors (Ciclibs) for the treatment of metastatic hormone receptor-positive and HER2-negative breast cancer (HR+/HER2-).Patients and MethodsA total of 222 patients were evaluated who received CDK4/6 inhibitors in the period from 2015 to 2021. Detailed clinical and demographic information was obtained on each patient and used to define clinical and demographic features associated with progression-free survival on CDK4/6 inhibitor-based therapies.ResultsIn this real-world analysis, the majority of patients received palbociclib as the CDK4/6 inhibitor with letrozole or fulvestrant as the predominant endocrine therapies. The median progression-free survival (PFS) in the letrozole (27.6 months) and fulvestrant (17.2 months) groups were comparable to that observed in clinical trials. As expected, age at start of the treatment and menopausal status influenced endocrine therapy utilization but were not associated with PFS. Patients with recurrent disease had shorter PFS (P = .0024) than those presenting with de novo metastasis. The presence of visceral metastasis trended toward shorter PFS (P = .051). Similarly, prior endocrine therapy (P = .003) or chemotherapy (P = .036) was associated with shorter PFS. Body mass index was not associated with PFS or with dose interruption and/or modification. While the number of minorities in this analysis is limited (n = 26), these patients as a group had statistically shorter PFS on treatment (P = .002).ConclusionsThe real-world progression-free survival with CDK4/6 inhibitors mimics that observed in the clinical trial. A number of clinical and demographic features were associated with PFS on CDK4/6 inhibitor-based therapy. Further studies are ongoing to validate these findings incorporating additional cancer centers.

This article reports a real-world experience related to the use of CDK4/6 inhibitors for the treatment of metastatic hormone receptor-positive and HER2-negative breast cancer, focusing on clinical and demographic features associated with progression-free survival.

Implications for PracticeThis study provides the real-world experience with the use of CDK4/6 inhibitors in the treatment of metastatic HR+/HER2− breast cancer. The work defines clinical and demographic features that impact the response to these agents and could offer guidance in preferred strategies for select manifestations of the disease. The study also suggests the need for more study of under-represented minority populations.  相似文献

IntroductionPalliative systemic therapy has been shown to improve survival in metastatic oesophagogastric cancer. Administration of palliative systemic therapy in metastatic oesophagogastric cancer varies between hospitals. We aimed to explore the association between the annual hospital volume of oesophagogastric cancer patients and survival.MethodsPatients diagnosed in the Netherlands between 2005 and 2013 with metastatic oesophagogastric cancer were identified in the Netherlands Cancer Registry. Patients were attributed according to three definitions of high volume: (1) high-volume incidence centre, (2) high-volume treatment centre and (3) high-volume surgical centre. Independent predictors for administration of palliative chemotherapy were evaluated by means of multivariable logistic regression analysis, and multivariable Cox proportional hazard regression analysis was performed to assess the impact of high-volume centres on survival.ResultsOur data set comprised 4078 patients with metastatic oesophageal cancer, and 5425 patients with metastatic gastric cancer, with a median overall survival of 20 weeks (95% confidence interval [CI] 19–21 weeks) and 16 weeks (95% CI 15–17 weeks), respectively. Patients with oesophageal cancer treated in a high-volume surgical centre (adjusted hazard ratio [HR] 0.80, 95% CI 0.70–0.91) and a high-volume treatment centre (adjusted HR 0.88, 95% CI 0.78–0.99) exhibited a decreased risk of death. For gastric cancer, patients treated in a high-volume surgical centre (adjusted HR 0.83, 95% CI 0.74–0.92) had a superior outcome.ConclusionImproved survival in patients undergoing palliative systemic therapy for oesophagogastric cancer was associated with treatment in high-volume treatment and surgical centres. Further research should be implemented to explore which specific factors of high-volume centres are associated with improved outcomes.  相似文献

BackgroundAlthough recent experimental data strongly suggest that platinum-based chemotherapy (PBCT) could improve the outcome of triple-negative breast cancer (TNBC), clinical data are lacking. Here, the authors reviewed clinical outcome in patients with metastatic TNBC treated with PBCT.Patients and methodsWe conducted a retrospective analysis of all patients (N = 143) treated for metastatic breast cancer with PBCT between 2000 and 2008, at Institut Curie, Paris, France. Ninety-three of them (63.7%) had TNBC. One-hundred twenty patients received cisplatin (CDDP). The main combination used was CDDP–ifosfamide, in 101 patients (70.2%).ResultsMedian follow-up was 44 months. For the overall population (N = 143), median overall survival (OS) and median progression-free survival (PFS) were 11 and 5 months, respectively. Objective response rate was 33.3% in the TNBC group versus 22% in non-TNBC, P = 0.1. We observed no difference of OS, PFS and response duration. Other prognostic factors for poor OS were visceral metastasis sites (P < 0.001). One patient died from sepsis during aplasia, 15 had to switch from CDDP to carboplatin because of CDDP-related toxicity.ConclusionsMetastatic TNBC patients treated with PBCT tended to have a higher response rate, without a significant improvement of PFS or OS, compared with other subtypes. Toxicity was acceptable. Longer observation and further analysis are warranted.  相似文献

BackgroundTo determine whether pulmonary metastasectomy or the addition of ifosfamide/dacarbazine to a doxorubicin-containing regimen offers a survival benefit to adult patients with metastatic leiomyosarcoma.Patients and methodsWe retrospectively collected data from 147 patients treated with a doxorubicin-containing regimen from 1998 to 2008.ResultsProgression-free survival (PFS) was 6.5 months (range 1–141 months). We did not identify an independent prognostic factor for PFS. Planned dose of doxorubicin was the sole parameter improving PFS [hazard ratio (HR) = 0.13, P = 0.023]. Overall survival (OS) was 17 months (range 1–115 months). The sole identified prognostic factor for OS was the interval between initial diagnosis and metastatic relapse. After adjustment to this prognostic factor, metastasectomy improved OS (HR = 0.52, P = 0.012) and the addition of ifosfamide seemed to worsen OS (HR = 1.42, P = 0.028).ConclusionIn our analysis, combined regimens did not improve the outcome. Maintenance of the doxorubicin dose was associated with improved PFS. Metastasectomy favorably influenced OS.  相似文献

Purpose: Oesophageal cancer is a highly aggressive disease with about 50% of patients presenting with advanced or metastatic disease at initial diagnosis. In this study we assessed combined microwave ablation (MWA) and systemic chemotherapy in the treatment of liver metastases arising from oesophageal squamous cell carcinoma (OSCC). Materials and methods: Between February 2009 and June 2014, OSCC patients who underwent percutaneous MWA?+?concurrent systemic chemotherapy and systemic chemotherapy alone for liver metastases were enrolled in this study. Overall survival (OS) and progression-free survival (PFS) were recorded and compared between groups. Results: In total 15 patients with 25 liver metastases who underwent ultrasound-guided percutaneous MWA and chemotherapy were enrolled in this study. Technical success was achieved in 96% (24/25) of metastatic liver tumours. No major or minor complications associated with MWA procedures were observed. The median OS and PFS from initial MWA were 13 months and 4 months. The 1-, 2-, 3-, 4-year OS rates after MWA were 53.3%, 26.7%, 13.3%, and 13.3%, respectively. The 1- and 2-year PFS rates after MWA were 26.7% and 13.3%. The OS and PFS of the MWA?+?systemic chemotherapy group were superior than those of patients who received systemic chemotherapy alone (P?=?0.011 and 0.030, respectively). Conclusions: Combined MWA with systemic chemotherapy is a feasible, safe and effective treatment for liver metastases from OSCC.  相似文献

The optimal first-line palliative systemic treatment strategy for metastatic esophagogastric cancer is not well defined. The aim of our study was to explore real-world use of first-line systemic treatment in esophagogastric cancer and assess the effect of treatment strategy on overall survival (OS), time to failure (TTF) of first-line treatment and toxicity. We selected synchronous metastatic esophagogastric cancer patients treated with systemic therapy (2010–2016) from the nationwide Netherlands Cancer Registry (n = 2,204). Systemic treatment strategies were divided into monotherapy, doublet and triplet chemotherapy, and trastuzumab-containing regimens. Data on OS were available for all patients, on TTF for patients diagnosed from 2010 to 2015 (n = 1,700), and on toxicity for patients diagnosed from 2010 to 2014 (n = 1,221). OS and TTF were analyzed using multivariable Cox regression, with adjustment for relevant tumor and patient characteristics. Up to 45 different systemic treatment regimens were found to be administered, with a median TTF of 4.6 and OS of 7.5 months. Most patients (45%) were treated with doublet chemotherapy; 34% received triplets, 10% monotherapy and 10% a trastuzumab-containing regimen. The highest median OS was found in patients receiving a trastuzumab-containing regimen (11.9 months). Triplet chemotherapy showed equal survival rates compared to doublets (OS: HR 0.92, 95%CI 0.83–1.02; TTF: HR 0.92, 95%CI 0.82–1.04) but significantly more grade 3–5 toxicity than doublets (33% vs. 21%, respectively). In conclusion, heterogeneity of first-line palliative systemic treatment in metastatic esophagogastric cancer patients is striking. Based on our data, doublet chemotherapy is the preferred treatment strategy because of similar survival and less toxicity compared to triplets.  相似文献

Hormone receptor (HR) status is an important prognostic factor for patients with metastatic breast cancer (MBC) and is also correlated with other prognostic factors, such as initial lymph node status, HER2-Neu status and age. The prognostic value of these other factors, however, is unknown when stratified by HR positive versus HR negative patients. The aim of this study was to evaluate prognostic factors for MBC survival in relation to HR status. Dutch women diagnosed with breast cancer in 2003–2006 treated with curative intent who developed MBC within 5 years of follow-up were selected from the Netherlands cancer registry (N = 2,001). Independent prognostic factors for survival after metastatic occurrence were determined by multivariable Cox survival analyses stratified by HR status. Interactions between HR status and prognostic factors were determined. Median survival for MBC patients with HR negative (HR?) tumours was 8 months, compared to 19 months for HR positive (HR+) patients. The prognostic value of lymph node status, HER2-Neu status, adjuvant endocrine treatment and first-line palliative chemotherapy was dependent on HR status. Initial lymph node status was independently associated with survival in HR? patients, but not in HR+ patients. HER2-Neu positive status was associated with better survival in both HR+ and HR? patients, although the association was stronger in HR? patients. Similarly, patients treated with first-line palliative chemotherapy fared better, especially HR? patients. HR+ patients had worse survival if they had received adjuvant endocrine treatment. This study shows that the prognostic value of various factors depends on HR status in MBC. This information may help physicians to determine individual prognostic profiles and therapeutic strategies for MBC patients.  相似文献

BackgroundOptimal chemotherapy for patients who received cisplatin for localized urothelial carcinoma (UC) and develop metastatic disease is unclear. We compared the efficacy of platinum-based (PBC) versus non–platinum-based (NPBC) first-line chemotherapy for metastasis.Patients and MethodsData were collected from the Retrospective International Study of Cancers of the Urothelial Tract (RISC), a database of 3024 patients from 28 international academic centers from 2005 to 2012. Patient inclusion criteria included: (1) predominant UC; (2) any primary tumor site; (3) cT2-4, cN0-N2, cM0; (4) prior receipt of perioperative/radiation cisplatin-containing chemotherapy; and (5) receipt of cytotoxic chemotherapy in the first-line metastatic setting. Multivariate Cox proportional hazards models were used to show progression-free survival (PFS) and overall survival (OS) from the first day of chemotherapy for metastatic disease to date of censor.ResultsEligibility criteria was met by 132 patients (n = 74 PBC; n = 58 NPBC). The median OS was 8.13 months (interquartile range, 4.87-16.64 months) and 8.77 months (interquartile range, 4.01-13.49 months) for PBC and NPBC, respectively. Neither OS (hazard ratio [HR], 1.04; 95% confidence interval [CI], 0.64-1.69; P = .87) nor PFS (HR, 0.86; 95% CI, 0.56-1.31; P = .48) differed for PBC versus NPBC. However, for patients who received chemotherapy more than a year after perioperative/radiation chemotherapy, OS was superior for PBC over NPBC (HR, 0.31; 95% CI, 0.10-0.92; P = .03).ConclusionsThere is no significant outcome difference between PBC and NPBC in patients with metastatic UC who previously received cisplatin-based chemotherapy for localized disease. However, if over a year has elapsed, return to PBC is associated with superior OS.  相似文献
