Purpose
To perform a retrospective analysis of the prognostic relevance of clinicopathologic parameters in a well-documented cohort of patients treated with all-trans-retinoic acid (ATRA)-based induction regimens in order to discover which indicators can predict a high risk of early death (ED) and patient survival.Patients and Methods
We analyzed data of 288 newly diagnosed adult acute promyelocytic leukemia patients in Hangzhou, China. The median follow-up time was 32 months (range, 6-78 months).Results
The 3-year disease-free and overall survival rates were 90.83% and 91.69%, respectively. In the multivariable analysis, older age (≥ 60 years) was the only independent risk factor for ED (hazard ratio [HR] = 15.057; P = .004). High white blood cell count was not a risk factor for ED (P = .055), but it was for relapse (HR = 2.7; P = .009). FLT3 mutation (HR = 3.9; 95% confidence interval, 1.4 to 10; P = .007) and older age (≥ 60 years) (HR = 5.3; 95% confidence interval, 2.4 to 11; P < .001) were prognostic factors for poorer disease-free and overall survival. Interestingly, CD15 negativity (HR = 0.23; P = .049) was a prognostic factor for relapse. The ED rate was 5.9% (17/288 patients).Conclusion
The perceived impact of the identification of these high-risk factors should be described in order to decide whether any modifications to treatment strategy should be entertained. 相似文献2.

Background
Infiltrating lobular carcinoma (ILC) represents about 10% of breast cancer and rarely shows overexpression of human epidermal growth factor receptor 2 (HER2). We compared biological and clinical characteristics of HER2-positive ILC versus HER2-positive infiltrating ductal carcinoma (IDC).Patients and Methods
We retrospectively analyzed the data of 328 patients with HER2-positive pure ductal or lobular breast carcinoma, comparing clinical and biological data at diagnosis as well as outcome between the 2 histologies. A gene-mutation analysis was performed in a subset of patients.Results
Two hundred ninety-one patients (88.7%) had IDC and 37 patients (11.3%) ILC. ILC resulted more frequently in multicenter (24.3% vs. 6.5%, P < .0001) and node-positive (54.1% vs. 45%, P = .013) disease of lower proliferative activity (Mib1 < 20%: 51.4% vs. 22.3%, P < .0001) and lower histologic grade (grade 3: 32.4% vs. 57.4%, P = .038). Disease recurred in 57 patients (17.4%) and involved the bone in 40% of ILC patients (vs. 17% of IDC patients) and the viscera in 30% of ILC patients (vs. 59.6% of IDC patients). No difference in the recurrence rate between the 2 histologies was observed in patients treated with adjuvant trastuzumab (12.5% of ILC patients and 8.3% of IDC patients). Exploratory molecular analysis revealed a higher frequency of mutations in ILC, with more cases of multiple mutations.Conclusion
HER2-positive ILC shows different biological behavior than IDC, with a possible higher mutation load. Despite lower proliferation activity and estrogen receptor expression in ILC breast cancer, trastuzumab is clearly an effective therapy for this histologic subtype. 相似文献3.

Objective
To determine long-term survival of visceral pleural invasion (VPI) and parenchymal invasion (PAI) (angiolymphatic and/or vascular) on survival of NSCLCs less than 30 mm in maximum diameter.Methods
Kaplan-Meier survivals for NSCLCs, with and without VPI and/or PAI, were determined for a prospective cohort of screening participants stratified by pathologic tumor size (≤10 mm, 11–20 mm, and 21–30 mm) and nodule consistency. Log-rank test statistics were calculated.Results
The frequency of PAI versus VPI was significantly lower in patients with subsolid nodules than in those with solid nodules (4.9% versus 27.7% [p < 0.0001]), and correspondingly, Kaplan-Meier lung cancer survival was significantly higher among patients with subsolid nodules (99.1% versus 91.3% [p = 0.0009]). Multivariable Cox regression found that only tumor diameter (adjusted hazard ratio [HR] =1.07, 95% confidence interval [CI]: 1.01–1.14, p = 0.02) and PAI (adjusted HR = 3.15, 95% CI: 1.25–7.90, p = 0.01) remained significant, whereas VPI was not significant (p = 0.15). When clinical and computed tomography findings were included with the pathologic findings, Cox regression showed that the risk of dying of lung cancer increased 10-fold (HR = 10.06, 95% CI: 1.35–75.30) for NSCLCs in patients with solid nodules and more than twofold (by a factor of 2.27) in patients with moderate to severe emphysema (HR = 2.27, 95% CI: 1.01–5.11), as well as with increasing tumor diameter (HR = 1.06, 95% CI: 1.01–1.13), whereas PAI was no longer significant (p = 0.19).Conclusions
Nodule consistency on computed tomography was a more significant prognostic indicator than either PAI or VPI. We propose that patients with NSCLC with VPI and a maximum tumor diameter of 30 mm or less not be upstaged to T2 without further large, multicenter studies of NSCLCs, stratified by the new T status and that classification be considered separately for patients with subsolid or solid nodules. 相似文献4.

Background
The prognostic value of tumor sidedness in metastatic colorectal cancer (CRC) has been established, but its impact on nonmetastatic disease remains unclear. Our study aimed to explore the prognostic effect of tumor sidedness by subgroup survival analyses, according to histology and tumor grade in stage I-IV CRCs.Methods
A retrospective population-based study was conducted based on Surveillance, Epidemiology and End Results (SEER) data. Population data in the SEER 9 registry (1975-2014) were used to determine survival trends of CRCs, and associated population data in the SEER 18 registry (2000 to 2014) were used to assess the prognostic impact of tumor sidedness on CRCs.Results
The 5-year cause-specific survival for all subgroups of CRCs improved from 1975 to 2014. Of 238,826 patients, 44.2% had right-sided cancer. Patients with right-sided cancer were more likely to be older, to be women, to have disease of mucinous or signet-ring cell histology, to have more poorly differentiated tumors, and to be diagnosed with a more advanced disease stage. Multivariate Cox regression showed stage I-II right-sided cancers had better cause-specific survival than the left-sided cancers (left colon: hazard ratio [HR] = 1.091, 95% confidence interval [CI], 1.052-1.132; rectum: HR = 1.363; 95% CI, 1.304-1.425; P < .001), while stage III and IV right-sided cancers had worse cause-specific survival. In subgroup analyses by histology and tumor grade within stage III CRCs, right-sided poorly differentiated mucinous adenocarcinoma showed significantly better survival (left colon: HR = 1.352; 95% CI, 1.145-1.596; rectum: HR = 1.125; 95% CI, 0.916-1.381; P = .002).Conclusion
The relationship between sidedness and prognosis in CRCs depends on stage and histopathologic characteristics, especially for stage III disease. 相似文献5.

Purpose
To assess the prognostic value of PI3K-AKT-mTOR signaling pathway up-regulation in a contemporary cohort of penile squamous-cell carcinoma (PSCC) patients.Patients and Methods
Tissue microarrays were constructed for 57 patients with invasive PSCC treated at our institution between 2000 and 2013. Immunohistochemical staining was performed for PTEN, AKT, and S6. Human papillomavirus (HPV) in-situ hybridization for high-risk subtypes was also performed. Biomarker expression was evaluated by a semiquantitative H score. Overall survival, disease-specific survival and recurrence-free survival stratified by biomarker expression (low vs. high) were estimated by the Kaplan-Meier method. Multivariable Cox regression models were used to determine predictors of mortality and recurrence.Results
HPV in-situ hybridization was positive in 23 patients (40%). PTEN was down-regulated in 43 patients (75%), while phosphorylated-AKT (p-AKT) and phosphorylated-S6 (p-S6) were up-regulated in 27 (47%) and 12 patients (21%), respectively. In multivariable Cox regression models, patients with low expression of p-AKT had an increased risk of recurrence (hazard ratio [HR] = 3.95; 95% confidence interval [CI], 1.47-10.59; P = .02), while those with low expression of p-S6 had an increased risk of overall mortality (HR = 6.15; 95% CI, 1.55-24.36; P = .01). HPV status was an independent predictor of overall survival (HR = 6.99; 95% CI, 2.42-20.16; P < .001) and disease-specific survival (HR = 6.74; 95% CI, 2.02-22.48; P = .002).Conclusion
PI3K-AKT-mTOR signaling pathway up-regulation and HPV coinfection in PSCC are associated with favorable disease. mTOR pathway biomarkers along with HPV status may represent novel prognosticators for risk stratification of PSCC patients and may help guide treatment decisions and follow-up strategies. These findings require further investigation. 相似文献6.

Background
Smoking increases the risk of developing renal cell carcinoma (RCC) but the effect of tobacco consumption on survival outcome of patients with metastatic RCC (mRCC) treated with targeted therapies has not been well characterized.Patients and Methods
The primary outcome was overall survival (OS) and secondary outcome was progression-free survival (PFS). Patients with mRCC were categorized as current, former, and nonsmokers at the time of starting targeted therapy. Smoking data from 1980 patients with mRCC treated with targeted therapy were collected through the International mRCC Database Consortium (IMDC) from 12 international cancer centers.Results
Although former and nonsmokers had comparable OS times (23.8 vs. 23.4 months; P = .898), current smokers had significantly shorter OS (16.1 months; P < .001) than nonsmokers. Current but not former smoking status was an independent poor prognosis factor (hazard ratio [HR], 1.3; P = .002) when adjusted for the IMDC risk criteria. Each pack-year increased the risk of death by 1% (HR, 1.01; P = .036). The duration of first-line therapy response was not different and was 7.7 months versus 7.5 months versus 6.4 months in never, former (P = .609), and current smokers (P = .839), respectively.Conclusion
Active smoking is associated with diminished OS in mRCC patients treated with targeted therapy agents. However, patients who quit smoking returned to a similar risk of death from RCC compared with patients who never smoked. Smoking cessation should be a counseling priority among mRCC patients receiving targeted agents and smoking should be considered as a confounding factor in major clinical trials. 相似文献7.

Background
Given the lack of established indications for elective nodal irradiation (ENI) in ypN0 patients after neoadjuvant chemotherapy (NAC) and breast-conserving surgery (BCS), we set out to investigate the role of ENI in ypN0 patients according to subtype and pathologic complete remission (pCR) status.Patients and Methods
We analyzed 261 patients who received NAC followed by BCS and adjuvant radiotherapy in 13 institutions of the Korean Radiation Oncology Group from 2005 to 2011. The tumors were classified into one of 3 subtypes: luminal (estrogen receptor positive or progesterone receptor positive and HER2 negative), HER2 (HER2 positive), or triple negative (estrogen receptor, progesterone receptor, and HER2 negative). We compared locoregional control (LRC), disease-free survival (DFS), and overall survival (OS) according to ENI in different subgroups generated by the subtype and pCR statuses.Results
In all patients, the 5-year LRC, DFS, and OS rates were 96.0%, 91.0%, and 96.8%, respectively. In all patients, axillary lymph node dissection was found to be the only favorable factor for LRC (P = .023) and DFS (P = .001). Age ≥ 50 years (P = .027), negative resection margin (P = .002), and axillary lymph node dissection (P = .002) were all favorable factors for OS. ENI did not affect LRC, DFS, or OS. Subgroup analysis by tumor subtype and pCR showed that ENI was not associated with greater LRC or DFS in any subgroups.Conclusion
In ypN0 patients after NAC and BCS, ENI did not improve LRC or survival, regardless of subtype or primary tumor response. This result should be verified through larger prospective trials. 相似文献8.

Background
Objections have been raised to performing risk-reducing salpingo-oophorectomy (RRSO) to reduce disease incidence and mortality of women with BRCA mutations. We aimed to examine the relationship between RRSO and breast cancer (BC) risk and mortality with a meta-analysis.Materials and Methods
We conducted a comprehensive literature search using the PubMed and Embase databases for literature published from these databases' creation to September 2017. Hazard ratio (HR) estimates were identified directly from the original articles. Pooled results were calculated on the basis of nonoverlapping studies by fixed-effect meta-analysis.Results
RRSO was associated with a significant reduction in the incidence of BC in women with BRCA1/2 mutations who had no history of BC (HR = 0.58; 95% confidence interval [CI], 0.37 to 0.78). Even in women with a history of BC, RRSO could reduce the risk of recurrence (HR = 0.50; 95% CI, 0.31 to 0.69). We further found that publication year was a critical interaction factor from a corresponding subgroup analyses in BC risk (Pheterogeneity = .024). In addition, we found that RRSO could improve the survival of women with BC (HR = 0.33; 95% CI, 0.28 to 0.38).Conclusion
Summary estimates presented here indicate that RRSO was closely related to the reduced risk of BC caused by BRCA mutations, but publication year was a critical interaction factor and it should be noted that more recent studies have failed to find a significant reduction in BC risk associated with RRSO. 相似文献9.

Introduction
Individual prediction of local recurrence (LR) risk after breast-conserving surgery (BCS) for ductal carcinoma-in-situ (DCIS) is needed to identify women at low risk, for whom radiotherapy may be omitted.Patients and Methods
Three predictive models of LR—clinicopathologic factors (CPF) alone; CPF + estrogen receptor (ER) + human epidermal growth factor receptor 2 (HER2); and CPF + DCIS score (DS)—were developed among 1102 cases of DCIS in patients with complete covariate and outcome data. Categorizations of discrete variables and transformations of continuous variables were examined in Cox models; 2-way interactions and interactions with time were assessed. Internal validation was performed by bootstrapping. Individual predicted 10-year LR risks were computed from covariate values, estimated regression parameters, and estimated baseline survival function. Accuracy was assessed by c statistics and calibration plots.Results
The strongest prediction model incorporated CPF + DS. The c statistics for CPF + DS, CPF + ER + HER2, or CPF-alone models were 0.7025, 0.6879, and 0.6825, respectively. The CPF + DS model was better calibrated at predicting low (≤ 10%) individual 10-year LR risks after BCS alone than those incorporating CPF + ER + HER2 or CPF alone, evidenced by c statistics and plots of observed by predicted risks. Among women aged ≥ 50 with no adverse CPF, the CPF + DS model identified the greatest proportion of women (62.3%) with predicted individual 10-year LR ≤ 10% without radiotherapy compared to the CPF + ER + HER2 (50.9%) or CPF alone (46.5%) models.Conclusion
Individual prediction of LR incorporating DS is more accurate and identifies a higher proportion of women with low predicted risk of LR after BCS alone, for whom radiotherapy may be omitted. 相似文献10.

Introduction
Clinical variables describing the natural history and longitudinal therapy outcomes of stage IV anaplastic lymphoma kinase gene rearrangement positive (ALK-positive) NSCLC and their relationship with long-term overall survival (OS) have not previously been described in detail.Methods
Patients with stage IV NSCLC treated with an ALK inhibitor at the University of Colorado Cancer Center from 2009 through November 2017 were identified retrospectively. OS curves were constructed by using Kaplan-Meier methods. Multivariate Cox proportional hazard analysis was used to determine the relationship of variables with OS.Results
Of the 110 patients with ALK-positive NSCLC who were identified, 105 received crizotinib as their initial ALK inhibitor. With a median follow-up time of 47 months, the median OS time from diagnosis of stage IV disease was 81 months (6.8 years). Brain metastases at diagnosis of stage IV disease (hazard ratio = 1.01, p = 0.971) and year of stage IV presentation (p = 0.887) did not influence OS. More organs with tumor at diagnosis of stage IV disease was associated with worse OS (HR = 1.49 for each additional organ with disease, including the CNS [p = 0.002]). Each additional month of pemetrexed-based therapy was associated with a 7% relative decrease in risk of death.Conclusion
Patients with stage IV ALK-positive NSCLC can have prolonged OS. Brain metastases at diagnosis of stage IV disease does not influence OS. Having more organs involved with tumor at stage IV presentation is associated with worse outcomes. Prolonged benefit from pemetrexed is associated with better outcomes. 相似文献11.

Background
The optimal number of high-dose cytarabine (HDAC) consolidation cycles before allogeneic hematopoietic cell transplantation (HCT) for acute myeloid leukemia is not fully standardized.Patients and Methods
This study evaluated the impact of HDAC consolidation cycles before allogeneic HCT in 194 patients with acute myeloid leukemia in first complete remission between 1998 and 2014. The patients were reclassified into 3 groups—no consolidation (C0, n = 20), 1 consolidation (C1, n = 115), and ≥ 2 consolidations (C2, n = 59)—by pre-HCT consolidation cycle.Results
The 3-year relapse-free survival rates was 45.9%, 66.9%, and 73.3% for the C0, C1, and C2 groups, respectively (P = .064), while the 3-year overall survival rates were 35.0%, 55.2%, and 67.5%, respectively (P = .106). The cumulative incidence of acute graft-versus-host disease (GVHD) was higher in the C2 group (38.7%) than in the C0 (22.2%) or C1 (17.7%) group (P = .018). However, the incidence of chronic GVHD showed no difference between the groups. Multivariate analysis for overall survival revealed the following independent factors: adverse cytogenetic risk (hazard ratio [HR] = 1.84, P = .046), C2 versus C0 (HR = 0.41, P = .037), pre-HCT status beyond CR1 versus CR1 (HR = 5.78, P < .001), and presence of chronic GVHD (HR = 0.45, P = .004).Conclusion
One or two cycles of HDAC consolidation therapy led to better subsequent HCT outcomes compared to the no–consolidation therapy group. 相似文献12.

Aims
Radiotherapy is an important treatment for many types of cancer, but a minority of patients suffer long-term side-effects of treatment. Multiple lines of evidence suggest a role for circadian rhythm in the development of radiotherapy late side-effects.Materials and methods
We carried out a study to examine the effect of radiotherapy timing in two breast cancer patient cohorts. The retrospective LeND cohort comprised 535 patients scored for late effects using the Late Effects of Normal Tissue-Subjective Objective Management Analytical (LENT-SOMA) scale. Acute effects were assessed prospectively in 343 patients from the REQUITE study using the CTCAE v4 scales. Genotyping was carried out for candidate circadian rhythm variants.Results
In the LeND cohort, patients who had radiotherapy in the morning had a significantly increased incidence of late toxicity in univariate (P = 0.03) and multivariate analysis (P = 0.01). Acute effects in the REQUITE group were also significantly increased in univariate analysis after morning treatment (P = 0.03) but not on multivariate analysis. Increased late effects in the LeND group receiving morning radiotherapy were associated with carriage of the PER3 variable number tandem repeat 4/4 genotype (P = 6 × 10?3) and the NOCT rs131116075 AA genotype (P = 5 × 10?3).Conclusion
Our results suggest that it may be possible to reduce toxicity associated with breast cancer radiotherapy by identifying gene variants that affect circadian rhythm and scheduling for appropriate morning or afternoon radiotherapy. 相似文献13.

Background
To investigate the superiority of breast-conserving surgery (BCS) plus radiotherapy (RT) compared with mastectomy alone for patients with stage I breast cancer in a real-world setting.Patients and Methods
The data from patients with histologically confirmed stage I breast cancer treated from 1999 to 2014 were retrospectively reviewed. The association of outcomes with the choice of treatment (BCS plus RT vs. mastectomy) was evaluated using multivariable proportional hazards regression and further confirmed using propensity score matching methods.Results
Of 6137 eligible patients in the present study, 1296 underwent BCS plus RT and 4841 underwent mastectomy plus axillary lymph node dissection without RT (mastectomy group). Multivariate analysis revealed that BCS plus RT was related to similar locoregional recurrence-free survival but greater distant metastasis-free survival (P = .003) and overall survival (P = .036) compared with mastectomy. For the 1252 pairs of patients matched using propensity score matching, the BCS plus RT groups enjoyed significantly greater 5-year overall survival (99.1% vs. 96.1%; P = .001), distant metastasis-free survival (97.0% vs. 92.2%; P < .001), and disease-free survival (95.3% vs. 90.2%; P = .001) compared with the mastectomy group.Conclusion
BCS plus RT provided better outcomes than mastectomy for eligible patients with stage I breast cancer and should be offered as a preferred treatment option. 相似文献14.

Background
Previous observational studies reported the superior survival of patients with early-stage breast cancer who underwent breast-conserving therapy (BCT, lumpectomy plus postsurgical radiation) compared to that of those who underwent mastectomy. Invasive lobular carcinoma (ILC) is not the same disease as invasive ductal carcinoma (IDC) as it has distinct biologic features and thus requires unique consideration and research.Methods
We selected women (≤50 years of age) from the Surveillance, Epidemiology, and End Results (SEER) database diagnosed with stage T1–2, N0–1, M0 primary breast cancer with invasive lobular features between 1998 and 2011, that were treated with either BCT or mastectomy with and without radiation. We assessed survival proportions using the Kaplan-Meier method and hazard ratios using Cox proportional hazards models. Breast cancer-specific survival (BCSS) served as the primary endpoint.Results
A total of 3393 eligible young ILC patients were identified, 1391 (41%) of which underwent lumpectomy followed by radiation. The 10-year BCSS rates for patients who received BCT, mastectomy alone and mastectomy with radiation were 95.7%, 94.2% and 89.3%, respectively. Multivariate analysis showed that BCSS was not improved in patients assigned to mastectomy alone group (HR = 0.86; 95% CI 0.57–1.28) or mastectomy with postsurgical radiation group (HR = 0.97; 95% CI 0.58–1.62) compared to that in those who underwent BCT. The results did not changed when evaluating the 1998–2004 and 2005–2011 time periods separately.Conclusion
None of the treatment demonstrated an absolute superiority in young women with early-stage ILC. Future studies with more detailed analyses of the confounding factors are worthwhile. 相似文献15.

Objectives
The paper aimed to compare the efficacy of log odds (LODDS) compared to a classification based on the distribution of involved lymph nodes (pN) and lymph node ratio (LNR).Methods
Material was collected retrospectively from an online survey-based database of the Polish Lung Cancer Group and included a group of 17,369 patients who received radical surgical treatment (R0) due to lung cancer.Results
In the whole group the median survival for N0, N1 and N2 was 76.1, 41.7 and 24.2 months, respectively. The median survival for individual LODDS categories (?6,-4], (?4,-3], (?3,-2], (?2,-1], (?1,0], (0,1] and (1,2] was 76.5, 76.3, 71.7, 45.4, 25.0, 19.1 and 17.7 months, respectively. The median survival for LNR in individual categories (0), (0,0.25], (0.25,05], (0.5075] and (0.75,1.0] was 75.6, 40.3, 24.1, 18.8 and 16.4 months, respectively. A multi-variant analysis demonstrated that each LODDS category is an independent prognostic factor: (?4,-3] (HR = 0.982; 95% CI 0.867–1.112; P = 0.775), (?3,-2] (HR = 1.114; 95% CI 0.984–1.262; P = 0.089), (?2,-1] (HR = 1.241; 95% CI 1.080–1.425; P = 0.002), (?1,0] (HR = 1.617; 95% CI 1.385–1.887; P < 0.0001), (0,1] (HR = 1.918; 95% CI 1.579–2.329; P < 0.0001) and (1,2] (HR = 2.016; 95% CI 1.579–2.573; P < 0.0001).Conclusions
Based on LODDS it is possible to discriminate patients with regard to lung cancer stage more effectively compared to pN and LNR classification, and it is also a better classification system. 相似文献16.

Background
Radium 223 was introduced for metastatic castration-resistant prostate cancer based on the results of a randomized controlled trial showing risk reduction for death and skeletal events. Our aim was to evaluate the outcome of patients receiving radium 223 in a real-world setting.Patients and Methods
We conducted a multicenter retrospective analysis in the Triveneto region of Italy.Results
One hundred fifty-eight patients received radium 223 in our region. After a median follow-up of 9.5 months, 75 patients died. The median overall survival (OS) was 14.2 months, and the median progression-free survival (PFS) was 6.2 months. Seventy-one (45%) patients achieved progression as best response. Thirty-seven (23%) patients stopped the treatment early because of progression. Eastern Cooperative Oncology Group performance status was prognostic for OS (18.4 vs. 12.3 vs. 7.5 months; 0 vs. 1, P = .0062; 0 vs. 2, P = .0002), whereas previous prostatectomy or docetaxel exposure were not. A neutrophil to lymphocytes ratio ≥ 3 significantly impacted OS (18.1 vs. 9.7 months; P < .001) and slightly impacted PFS (6.6 vs. 5.6 months; P = .05). Patients with a baseline alkaline phosphatase (ALP) value ≥ 220 U/L had worse OS and PFS (24.1 vs. 10.5 months; 7.2 vs. 5.5 months; P < .001). Patients with changes in ALP value achieved better OS (P = .029) and PFS (P = .002). There was no difference according to the line of therapy (0 vs. ≥ 1; P = .490). The main grade 3/4 toxicities were anemia, asthenia, and thrombocytopenia.Conclusion
This large real-world report confirms comparable OS and PFS data when compared with the pivotal study, as well as the predictive role of ALP and neutrophil to lymphocytes ratio. The definition of the optimal position of radium 223 in the treatment of metastatic castration-resistant prostate cancer has still to be defined. 相似文献17.

Aims
Delaying progression, ameliorating symptoms and maintaining quality of life (QoL) are primary aims of treatment for metastatic castrate-resistant prostate cancer (mCRPC). Real-world rather than clinical trial data about symptoms and side-effects are sparse. In EXTREQOL, patients' QoL, pain and information needs were recorded during treatment.Material and methods
Men with mCRPC from 20 UK cancer centres starting various systemic mCRPC treatments completed QoL, pain and information needs questionnaires at baseline, 3 and 6 months.Results
In total, 132 patients were recruited. Overall QoL declined significantly by 6 months (Functional Assessment of Cancer Therapy-Prostate [FACT-P] mean = –3.89, 95% confidence interval –6.7 to –1.05, P = 0.007; Trial Outcome Index [TOI] analysis mean = –3.10, 95% confidence interval –5.34 to –0.83, P = 0.007). Those who came off novel therapy and remained on luteinising hormone-releasing hormone agonist therapy alone had worse scores than patients receiving concomitant chemotherapy (Prostate Concerns Subscale mean difference = –4.45, 95% confidence interval –7.06 to –1.83, P = 0.001; TOI mean difference = –5.62, 95% confidence interval –10.97 to –0.26, P = 0.040). At 3 and 6 months, men who reported pain at baseline improved (43%, 40%), but for others pain levels remained the same (45%, 42%) or worsened (13%, 18%). Information regarding supportive care was lacking throughout the period of time on the study.Conclusion
Most mCRPC treated patients experience reduced QoL and inadequate pain control. More help with pain management and better information provision regarding supportive care is warranted. 相似文献18.

Background
Radiographic progression-free survival (rPFS) is associated with overall survival (OS) in chemotherapy-naïve metastatic castration-resistant prostate cancer (mCRPC) patients. Using readily assessable baseline clinical and laboratory parameters, we developed a prognostic index model for rPFS in chemotherapy-naïve mCRPC patients without visceral disease who were treated with abiraterone acetate plus prednisone.Methods
Data from the abiraterone acetate plus prednisone arm of COU-AA-302 were used. rPFS was defined based on modified Prostate Cancer Working Group 2 criteria. Baseline variables were assessed for association with rPFS through univariate Cox modeling. The lower (LLN) and upper (ULN) limits of laboratory normal were used to dichotomize most laboratory parameters; baseline median was used to dichotomize prostate-specific antigen (PSA). Prognostic factors for rPFS were identified by multivariate Cox modeling. Model accuracy was estimated by the C-index.Results
Presence of lymph node metastasis (hazard ratio [HR] = 1.76, P < .0001), lactate dehydrogenase > ULN (234 IU/L) (HR = 1.71, P = .0001), ≥ 10 bone metastases (HR = 1.71, P = .0015), hemoglobin ≤ LLN (12.7 g/dL) (HR = 1.47, P = .0030) and PSA > 39.5 ng/mL (HR = 1.42, P = .0078) were associated with poor outcome. Patients were categorized into 3 prognostic groups (good, n = 230; intermediate, n = 152; poor, n = 164) based on number of risk factors. Median rPFS was calculated (27.6, 16.6, and 8.3 months for good, intermediate, and poor, respectively). The C-index was 0.83 (95% confidence interval = 0.73-0.91).Conclusions
The prognostic index model for rPFS reveals differential outcomes based on factors readily available in clinical practice. If validated, this model can be integrated into clinical practice and design of risk-stratified trials. 相似文献19.

Purpose
We analyzed positron emission tomography-computed tomography (PET-CT) in patients with stage III non–small-cell lung cancer (NSCLC) undergoing concurrent chemoradiotherapy (CRT) to examine the prognostic value of PET-CT parameters according to histologic subtypes (squamous cell carcinoma [SqCC] and adenocarcinoma [ADC]).Methods
A total of 130 patients with stage III NSCLC who underwent definitive CRT were identified. We obtained PET-CT parameters such as maximum (SUVmax) and mean (SUVmean) standardized uptake value, total lesion glycolysis (TLG), metabolic tumor volume (MTV), and coefficient of variation (CV). Each parameter was bifurcated based on the optimal cutoff, and propensity score matching was performed between the SqCC and ADC groups.Results
There were 108 patients with SqCC or ADC, and 44 patients each were allocated to the SqCC and ADC groups via propensity score matching. SUVmax, SUVmean, TLG, and MTV values were significantly higher in SqCC than in ADC (P = .004, P = .006, P = .003, and P = .03, respectively). In the SqCC group, PET-CT parameters were not associated with survival outcomes. However, in the ADC group, SUVmax and SUVmean were related to locoregional progression-free survival (P = .008 and P = .017, respectively), and TLG and MTV were related to overall survival (P = .044 and P < .001, respectively). In addition, patients with ADC showed more frequent distant metastasis (P = .011) and worse distant metastasis-free survival compared with patients with SqCC (P = .009).Conclusions
PET-CT provided different prognostic implications between SqCC and ADC in patients with locally advanced NSCLC receiving radical CRT. This suggests that it is necessary to consider the histologic subtype and PET-CT parameters concurrently when predicting survival outcomes. 相似文献20.
