Background
The study aimed to evaluate the feasibility and reliability of ultrasound-guided vacuum-assisted breast biopsy (US-VABB) for sampling of microcalcifications indicative of cancer when stereotactic vacuum-assisted breast biopsy cannot be performed because of reasons such as thin breast tissue, insufficient thickness at compression, and microcalcification situated close to the chest wall or in breast tissue of the axillary tail.Patients and Methods
The study population was selected from among 187 patients with microcalcifications detected on mammogram. The findings were classified using the American College of Radiology criteria as Breast Imaging Reporting and Data System 3, 4, or 5. 30 Thirty were not eligible for stereotactic guidance because of reasons such as small breast size, compression thickness <2 cm, or microcalcification located in the axillary tails or close to chest wall. In 23 patients microcalcifications were detected at ultrasound, and US-VABB was performed. The other 7 patients underwent surgical biopsy. In the 23 patients who underwent US-VABB, multiple core samples were taken after a specimen mammography to ensure that microcalcifications were included.Results
Biopsy was successful in all cases of US-VABB. The procedure was well tolerated, and there were no complications.Conclusion
US-VABB should be preferred over diagnostic surgical biopsy when microcalcifications are sonographically visible and stereotactic guidance is contraindicated. The procedure appears to be reliable and accurate, with added advantages such as low cost and absence of radiation exposure. 相似文献2.

Background
As oral targeted agents, such as ibrutinib, become more widely used, understanding the impact of suboptimal dosing on overall survival (OS) and progression-free survival (PFS) outside of clinical trials is imperative.Patients and Methods
Data on ibrutinib discontinuation, dose reductions, and treatment interruptions were collected on 170 non-Hodgkin lymphoma and chronic lymphocytic leukemia (CLL; n = 115, 64%) patients treated with ibrutinib at a single institution. Ibrutinib dose adherence was calculated as the proportion of days in which ibrutinib was administered out of the total number of days ibrutinib was prescribed in the first 8 weeks. Kaplan-Meier curves and log-rank tests were used to compare conditional survival outcomes beyond 8 weeks in patients with ≥ 80% dose adherence and patients with < 80% dose adherence.Results
Median OS among those who discontinued therapy for progression was poor (n = 51, 1.7 months; 95% confidence interval, 0.3-3.7). Lower dose adherence (< 80%) was associated with significantly worse PFS (P = .002) and OS (P = .021). However, among CLL patients, lower dose adherence was only associated with worse PFS (P = .043). Patients with early dose reductions had significantly worse PFS (P = .004) and OS (P = .014). Patients with dose interruptions lasting > 1 week had worse PFS (P = .047) but not OS (P = .577).Conclusion
In this observational study, non-Hodgkin lymphoma and CLL patients experienced poor outcomes after discontinuing ibrutinib for disease progression. The inferior survival related to suboptimal dose adherence of ibrutinib was predominantly due to early dose reduction. These data confirm poor survival in CLL and lymphoma patients alike after ibrutinib discontinuation, and support recommendations for full dose at treatment initiation. 相似文献3.

Introduction
Lung cancer patients with tumors harboring actionable alterations can achieve very durable responses to first-line targeted therapy. However, identifying targetable alterations using next-generation sequencing (NGS) is a complex and time-intensive process. As actionable genetic alterations are enriched in lung cancers arising in patients with limited smoking history, we designed a workflow to expedite NGS testing for this group.Methods
We developed a protocol to allow for next-day extraction of nucleic acids from frozen tissue. Specimens were designated as high priority during sequencing. We determined the interval between biopsy and NGS results to evaluate whether the workflow reduced the pre-analytical period and in-laboratory turnaround time and allowed for rapid initiation of genotype-matched therapy.Results
Between January 2017 and May 2018, 21 patients participated in the expedited sequencing program. The median interval between biopsy and NGS results was 10.7 days. Six patients received results within 1 week of biopsy. Performing molecular analysis on frozen tissue and prioritizing sequencing and analysis of these specimens reduced the pre-analytical period from 3.5 to 1.3 days (p < 0.0001) and shortened in-laboratory turnaround time by 3 days (11.8 versus 8.4 business days, p < 0.0001). Ninety-three percent of patients with an actionable molecular alteration received first-line targeted therapy. The median time-to-initiation of treatment was 19.7 days from biopsy.Conclusions
Sequencing and analyzing nucleic acids from frozen tissue is a practical strategy for shortening the time to matched therapy. The significant advantage of upfront treatment with targeted therapies in subsets of lung cancer patients provides rationale for developing workflows that accelerate comprehensive molecular analysis. 相似文献4.

Introduction
In recent years, considerable progress has been made in the treatment of patients with chronic lymphocytic leukemia (CLL), and new potent drugs have become available. Therefore, the CLL working party revised the Dutch guidelines. Not only efficacy but also quality of life and socio-economic impact were taken into account in the formulation of treatment recommendations.Materials and Methods
The working party discussed a set of questions regarding diagnostic tests and treatment and wrote the draft guideline. This was evidence-based whenever possible, but in cases of low evidence, an expert-based recommendation was formulated with input of the entire working party. The draft guideline was sent to all hematologists in the Netherlands for comment and was subsequently approved.Results
Recommendations were formulated on diagnostic tests and work-up before treatment. Also, recommendations were made for treatment with fludarabine-cyclophosphamide-rituximab, bendamustine-rituximab, chlorambucil with anti-CD20 antibody, ibrutinib, idelalisib-rituximab, venetoclax, and allogeneic stem cell transplantation.Conclusion
In the revised Dutch CLL guidelines, chemo-immunotherapy is still the cornerstone of CLL treatment with novel targeted drugs for specific risk groups. 相似文献5.

Background
Colon cancer is the third most frequent cancer diagnosis, and primary payer status has been shown to be associated with treatment modalities and survival in cancer patients. The goal of our study was to determine the between-insurance differences in survival in patients with clinical stage III colon cancer using data from the National Cancer Database (NCDB).Materials and Methods
We identified 130,998 patients with clinical stage III colon cancer in the NCDB diagnosed from 2004 to 2012. Kaplan-Meier curves and multivariable Cox regression models were used to determine the association between insurance status and survival.Results
Patients with private insurance plans were 28%, 30%, and 16% less likely to die than were uninsured patients, Medicaid recipients, and Medicare beneficiaries, respectively. Medicare patients were 14% were less likely to die compared with uninsured patients. Patients receiving chemotherapy were, on average, 65% less likely to die compared with the patients not receiving chemotherapy.Conclusion
Private insurance and a greater socioeconomic status were associated with increased patient survival compared with other insurance plans or the lack of insurance. Future research should continue to unravel how socioeconomic status and insurance status contribute to the quality of care and survival of oncologic patients. 相似文献6.

Introduction
Although a considerable improvement in survival of patients with acute promyelocytic leukemia (APL) has been seen over the past decades, real-life outcomes seem to be worse than those reported by prospective studies. We aim to describe clinical characteristics and outcomes of adult patients diagnosed with APL in an academic hospital from the University of Sao Paulo.Patients and Methods
We retrospectively reviewed the medical charts of 61 patients with APL diagnosed between January 2007 and May 2017. Baseline clinical features and follow-up data were collected, focusing on early toxicity variables such as infection, bleeding, and thrombosis in the first 30 days from diagnosis.Results
Among the 61 patients with APL, 54 received any chemotherapy. All patients also received all-trans retinoic acid (ATRA). Bleeding events were the main cause of death before receiving chemotherapy. Most patients belonged to the intermediate (43%) and high-risk (41%) groups, according to Sanz score. The ‘7 + 3 + ATRA’ regimen was the most used regimen (n = 38). An early death rate of 20% was found, predominantly owing to sepsis. After a median follow-up of 5 years, only 1 relapse was diagnosed. The overall survival at 5 years was 59%.Discussion
In comparison with prospective trials with ATRA-based regimens, we found an inferior overall survival, mostly on account of a high early-death rate. Our results are in line with other real-life retrospective reports published in the past decades.Conclusion
Results of real-life studies differ from those found by prospective trials. Accordingly, early actions and supportive care are still needed, aiming to decrease toxicity, especially in developing countries. 相似文献7.

Introduction
Breast cancer (BC) is the most common cancer in women, and the incidence of brain metastasis (BM) from BC ranges from 20% to 30%, with a median survival of 10 to 15 months. Previous reports have shown that the presence of obesity or diabetes negatively impacts survival. The present study investigates the association between obesity or diabetes mellitus (DM) and overall survival of patients with BC with BM.Materials and Methods
A database from 2 referral centers for the period of July 2014 to February 2018 was analyzed. The inclusion criteria were as follows: patients who had a confirmed diagnosis of BC with BM were followed and treated at these centers. Demographic data, body weight and height, clinical and oncologic history, functional status, prognostic scales, and prognoses were examined.Results
A total of 228 patients were included. The median age at BM was 50 years; the median survival after diagnosis was 12.1 months; 108 patients had a body mass index (BMI) ≥ 25, and 40 (17%) patients had DM. The association between survival and the presence of BMI > 25 exhibited a P value of 0.3.Discussion
We found no association between overweight, obesity, or DM and survival in patients with BC with BM. The role of obesity in cancer is a robust research topic, as there are many questions to be answered.Conclusion
Obesity as a prognostic indicator should be further studied, because we found no association between overall survival and either patients with BM from BC with a BMI > 25 or those with normal weight. 相似文献8.

Background
Racial/ethnic minority groups, including Hispanic Americans (HAs) and Native Americans (NAs), have a heavier burden of kidney cancer than European Americans (EAs). We investigated variations in clinical characteristics of HA and NA patients with renal cell carcinoma (RCC) who were previously underrepresented.Materials and Methods
Clinical records of 294 patients with RCC (151 EAs, 95 HAs, 22 NAs, and 26 others) without prior diagnosis of cancer were reviewed. Logistic regression analysis was performed to understand patients’ clinical characteristics.Results
HAs had about 5 years younger average age at diagnosis than EAs (55.8 vs. 60.5 years) and an almost 3-fold increased odds of diagnosis before age 50 years (odds ratio [OR], 2.77; 95% confidence interval [CI], 1.39-5.54). The mean age of diagnosis among NAs was 49.7 years, and NAs had an over 6-fold higher odds of diagnosis at a younger age (OR, 6.23; 95% CI, 2.00-19.46). Clear-cell RCC (ccRCC) was more common in HAs and NAs than EAs. Over 90% of HA patients had ccRCC, whereas only 78.8% of EA patients had ccRCC. HAs had increased odds of diagnosis with ccRCC compared with EAs (OR, 2.79; 95% CI, 1.15-6.80). Among HAs, older patients and patients who spoke Spanish as their primary language were more likely to have advanced stage RCC at diagnosis (OR, 10.48; 95% CI, 1.69-64.89 and OR, 4.61; 95% CI, 1.38-15.40).Conclusion
HA and NA patients with RCC had different clinical characteristics than EA patients. It is necessary to better understand the clinical characteristics of these underserved HA and NA populations with high kidney cancer burden. 相似文献9.
Purpose
To assess the pharmacologic costs of second-line treatments for metastatic renal-cell cancer (mRCC).Methods
The present evaluation was restricted to pivotal phase 3 randomized controlled trials in second-line for mRCC. We calculated the pharmacologic costs necessary to get the benefit in progression-free survival and overall survival (OS) for each trial. The costs of drugs are at the pharmacy of our hospital and are expressed in euros.Results
Our analysis evaluated 5 phase 3 randomized controlled trials including 3112 patients. The lowest cost per month of progression-free survival and OS gained was associated with the use of cabozantinib (€2006 and €1473, respectively), while everolimus had the highest cost per month of OS gained (€28,590).Conclusion
Combining pharmacologic costs of drugs with the measure of efficacy represented by OS, cabozantinib is a cost-effective second-line treatments for patients with mRCC. 相似文献10.

Background
Despite therapeutic advancements that have significantly improved outcomes in multiple myeloma (MM), it remains an incurable disease. Patients with relapsed and/or refractory MM have an aggressive disease course, with inferior outcomes, necessitating the need for agents with novel therapeutic mechanisms. We present the results of a completed phase I trial of single-agent lorvotuzumab mertansine, a unique antibody-drug conjugate targeting CD56, which is frequently expressed in MM.Patients and Methods
Thirty-seven patients with relapsed MM were enrolled in a dose-escalation phase I clinical trial to determine the maximum tolerated dose of lorvotuzumab mertansine (112 mg/m2), followed by an expansion phase at the maximum tolerated dose.Results
Despite a high proportion of patients with relapsed and/or refractory MM (56.8%), stable disease or better was noted in 42.9% of patients, and these patients had a long duration of response (median, 15.5 months). The adverse event profile was favorable, with a low incidence of grade 3/4 adverse events and no infusion-related reactions. No humoral responses were detected against the study drug.Conclusion
This completed phase I trial of single-agent lorvotuzumab mertansine provides ample evidence of safety and signals of clinical activity for this agent, warranting its further clinical development as part of combination regimens for the management of MM. 相似文献11.

Background
Initial treatment of mantle cell lymphoma (MCL) incorporating autologous stem cell transplantation affords long-term remissions, but relapses still occur. Optimal pretransplant therapy will afford high complete response rates and not impair stem cell collection. Incorporation of bortezomib represents a natural evolution of pretransplant therapy, given its proven first-line efficacy and minimal impact on stem cell collection.Patients and Methods
At the University of Washington/Seattle Cancer Care Alliance and the Cleveland Clinic Foundation, we developed modified VR-CAP/R+ara-C (bortezomib, rituximab, cyclophosphamide, doxorubicin, and prednisone, alternating with rituximab and high-dose cytarabine), for transplant-eligible patients with MCL. This regimen was administered as standard-of-care, pretransplant therapy to consecutive patients with MCL from April 2015 to the present.Results
A total of 37 patients were treated with this regimen, including 18 at the University of Washington/Seattle Cancer Care Alliance and 19 at the Cleveland Clinic Foundation. Most patients had intermediate- or high-risk disease by both (mantle-cell lymphoma international prognostic index (MIPI)-B and MIPI-C category. Complete response to induction was achieved in 32 (86%) of 37 evaluable patients; 2 achieved partial response, and 3 had primary refractory disease. Stem cell collection was successful in 1 attempt in 30 of 32 patients. The median follow-up of survivors measured from start of treatment is 17.4 months. Five patients have progressed, and 4 have died (2 owing to lymphoma, 2 from toxicity).Conclusion
Modified VR-CAP/R+ara-C is feasible pretransplant therapy for patients with MCL and is associated with a high rate of complete response and eligibility for autologous stem cell transplantation. 相似文献12.

Background
Peripheral T-cell lymphomas (PTCLs) are generally aggressive non-Hodgkin lymphomas that portend poor prognosis with currently available therapies. Bexarotene, a retinoic acid derivative, has efficacy in cutaneous T-cell lymphomas, but its activity in PTCL is unknown.Patients and Methods
We conducted a retrospective, single-institution, review of off-label bexarotene therapy in patients with PTCL between 2005 and 2016.Results
Twelve patients were treated with bexarotene as monotherapy: 3 patients with PTCL, not otherwise specified, and 9 patients with angioimmunoblastic T-cell lymphoma. Bexarotene doses of 300 mg/m2 daily or 150 mg/m2 were used for all patients. The treatment was well-tolerated. The most common toxicities included hypothyroidism and hyperlipidemia, which were effectively managed. The overall response rate for all patients was 58% with a median duration of response of 11 months (95% confidence interval [CI], 1.3 months to not estimable). Among patients with angioimmunoblastic T-cell lymphoma, there was a 44% overall response rate. The median progression-free survival for all patients was 2.1 months (95% CI, 1.1 months to not estimable), and the median overall survival was 14.9 months (95% CI, 2.1-73.1 months).Conclusion
Bexarotene monotherapy is well-tolerated and has encouraging activity in PTCL that warrants further investigation in prospective clinical trials. 相似文献14.

Introduction
Histologic transformation from NSCLC to SCLC is a mechanism of resistance in EGFR-mutant tumors but is also occasionally observed in nonmutated NSCLC.Methods
We performed a multicenter retrospective collection of cases presenting between 2005 and 2017. The objectives were to analyze survival data and to define epidemiologic, clinical, treatment and histomolecular characteristics at both the time of diagnosis of NSCLC and of SCLC.Results
Forty-eight EGFR-mutant NSCLC and 13 non–EGFR-mutant cases were registered. Most EGFR-mutant tumors retained the same EGFR mutation after transformation. The median time to SCLC transformation was shorter in the EGFR-mutant group than in non-EFGR mutants (16 months versus 26 months (p = 0.01)). Both tumors were responsive to platinum etoposide regimens (45% partial response for the EGFR-mutant group versus 40% for non-EFGR mutants). The median overall survival rates were 28 months in the EGFR-mutant group versus 37 months in the non–EFGR-mutant group, respectively. After transformation, the median overall survival was 9 months in the non–EGFR-mutant group versus 10 months in the EGFR-mutant group.Conclusions
Transformation into SCLC seems to occur more quickly in EGFR mutated tumors; however, once the tumor is transformed its survival and response to treatment seems comparable to that of classical SCLC. 相似文献15.

Background
Cardiovascular events (CVEs) have been observed in patients with chronic myeloid leukemia treated with second-generation tyrosine kinase inhibitors.Patients and Methods
We retrospectively evaluated the incidence of CVEs on 233 consecutive patients with chronic myeloid leukemia, of which 116 were treated with imatinib, 75 with dasatinib, and 42 with nilotinib. The median follow-up was 2047, 1712, and 1773 days, respectively.Results
The cumulative incidence of CVEs was 4.29%. Three events occurred during dasatinib treatment, 6 during nilotinib treatment, and none during imatinib treatment (P ≤ .001). Arterial occlusive events occurred in 2 (2.6%) of 75 patients treated with dasatinib and in 6 (14.2%) of 42 patients treated with nilotinib (P ≤ .001). Furthermore, all of them occurred in patients with high-risk (n = 2) and very high-risk (n = 6) cardiovascular risk, contributing to 4.3% of mortality.Conclusion
CVEs were more frequent in patients treated with second-generation tyrosine kinase inhibitors. Arterial occlusive events were more frequent in patients treated with nilotinib, with high and very high cardiovascular risk. 相似文献16.

Background
RAS and RAF mutations in colorectal cancer (CRC) hold value in precision medicine. Liquid biopsy is an alternative to tumor tissue biopsy, and circulating tumor DNA (ctDNA) has been intensively investigated, but the clinical relevance of RAS and RAF mutations in plasma is yet to be determined. This study aimed to investigate the clinical aspects of RAS/RAF mutations during combination treatment.Patients and Methods
Patients with RAS/RAF tumor wild-type metastatic CRC treated with combination chemotherapy and an EGFR inhibitor were included. Blood samples were collected at baseline and every treatment cycle and analyzed for 31 RAS, RAF, and EGFR mutations until progressive disease or censoring using droplet digital PCR.Results
Forty-six patients were prospectively enrolled onto the study. At baseline, 7% had detectable RAS/RAF mutations in ctDNA. During the treatment course, the fraction of patients with mutated ctDNA increased to 22%. The emergence of mutations did not correlate with response or risk of progression while receiving treatment (P = 1.0).Conclusion
Emergence of plasma RAS/RAF mutations was not correlated with the effect of combination chemotherapy and EGFR inhibition in patients with RAS/RAF wild-type metastatic CRC. 相似文献17.

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18.

Introduction
Colorectal cancer is a major public health issue, with incidences continuing to rise owing to the growing and aging world population. Current screening strategies for colorectal cancer diagnosis suffer from various limitations, including invasiveness and poor uptake. Consequently, there is an unmet clinical need for a minimally invasive, sensitive, and specific method for detecting the presence of colorectal cancer and pre-malignant lesions.Patients and Methods
An indirect enzyme-linked immunosorbent assay was used to measure the primary (IgM) and secondary (IgG) adaptive humoral immune responses to a panel of previously identified cancer antigens in the sera of normal and adenoma samples, and sera from patients with colorectal cancer.Results
An optimal panel of 7 biomarkers capable of identifying patients with colorectal cancer as distinct from both normal and adenoma samples is identified. The cumulative sensitivity and specificity of the assay are 70.8% and 86.5%, respectively. The positive and negative predictive values of the cohort are 77.3% and 82.1%. This assay was not able to accurately discriminate between normal and adenoma samples. Patients whose serum was positive for the presence of anti-ICLN IgM autoantibodies had a significantly poorer 5-year survival than patients whose serum was negative (P = .004).Conclusion
This study describes a novel minimally invasive enzyme-linked immunosorbent assay-based method, capable of identifying patients with colorectal cancer as distinct from both normal and adenoma samples. Patients are likely to be far more amenable to a blood-based test such as the one described herein, rather than a fecal-based test, likely leading to increased patient uptake. 相似文献19.
