Osimertinib after Chemoradiotherapy in Stage III EGFR-Mutated NSCLC.

BACKGROUND: Osimertinib is a recommended treatment for advanced non-small-cell lung cancer (NSCLC) with an epidermal growth factor receptor (EGFR) mutation and as adjuvant treatment for resected EGFR-mutated NSCLC. EGFR-tyrosine kinase inhibitors have shown preliminary efficacy in unresectable stage III EGFR-mutated NSCLC. METHODS: In this phase 3, double-blind, placebo-controlled trial, we randomly assigned patients with unresectable EGFR-mutated stage III NSCLC without progression during or after chemoradiotherapy to receive osimertinib or placebo until disease progression occurred (as assessed by blinded independent central review) or the regimen was discontinued. The primary end point was progression-free survival as assessed by blinded independent central review. RESULTS: A total of 216 patients who had undergone chemoradiotherapy were randomly assigned to receive osimertinib (143 patients) or placebo (73 patients). Osimertinib resulted in a significant progression-free survival benefit as compared with placebo: the median progression-free survival was 39.1 months with osimertinib versus 5.6 months with placebo, with a hazard ratio for disease progression or death of 0.16 (95% confidence interval [CI], 0.10 to 0.24; P<0.001). The percentage of patients who were alive and progression free at 12 months was 74% (95% CI, 65 to 80) with osimertinib and 22% (95% CI, 13 to 32) with placebo. Interim overall survival data (maturity, 20%) showed 36-month overall survival among 84% of patients with osimertinib (95% CI, 75 to 89) and 74% with placebo (95% CI, 57 to 85), with a hazard ratio for death of 0.81 (95% CI, 0.42 to 1.56; P = 0.53). The incidence of adverse events of grade 3 or higher was 35% in the osimertinib group and 12% in the placebo group; radiation pneumonitis (majority grade, 1 to 2) was reported in 48% and 38%, respectively. No new safety concerns emerged. CONCLUSIONS: Treatment with osimertinib resulted in significantly longer progression-free survival than placebo in patients with unresectable stage III EGFR-mutated NSCLC.

A phase 2 randomized clinical trial of abiraterone plus ADT, apalutamide, or abiraterone and apalutamide in patients with advanced prostate cancer with non-castrate testosterone levels (LACOG 0415).

BACKGROUND: Androgen deprivation therapy (ADT) combined with apalutamide, abiraterone acetate plus prednisone, enzalutamide, or docetaxel are the standard treatments for advanced castration-sensitive prostate cancer (CSPC). We investigated ADT-free alternatives for advanced CSPC. PATIENTS AND METHODS: LACOG 0415 is a phase 2, open-label, non-comparative, randomized trial. Patients with advanced CSPC were randomized (1:1:1) to receive goserelin plus abiraterone acetate and prednisone (ADT plus AAP arm), apalutamide (APA arm), or apalutamide plus abiraterone acetate and prednisone (APA plus AAP arm). The primary endpoint was the proportion of patients with PSA of ≤0.2 ng/mL at week 25 in the modified intention-to-treat population. Safety analyses were performed in all patients with at least one dose of the study drug. RESULTS: Of 128 randomized patients, 120 patients were evaluable for PSA response at week 25; 17.2% had a high-risk biochemical recurrence, 8.6% had locally advanced disease, and 74.2% had distant metastases. At week 25, PSA of ≤0.2 ng/mL was observed in 75.6% (95%CI 59.7%-87.6%), 60.0% (95%CI 43.3%-75.1%), and 79.5% (95%CI 63.5%-90.7%) of patients in ADT plus AAP, APA, and APA plus AAP arms, respectively. PSA decline of ≥80% was observed in 100%, 90.0%, and 97.4%, respectively. Grade 3-4 AEs were observed in 31.0%, 21.4% and 36.4%, respectively. Testosterone levels increased significantly in the APA arm and decreased significantly in ADT plus AAP and APA plus AAP arms. CONCLUSIONS: ADT-free alternatives provide a high PSA response in advanced CSPC, although the APA arm did not reach the expected rate of PSA of ≤0.2 ng/mL at week 25. These results warrant further investigation of ADT-free treatments as alternatives in advanced CSPC. SOURCE STUDY REGISTRATION: ClinicalTrials.govNCT02867020.

Biomarker Analysis of the Phase III NALA Study of Neratinib + Capecitabine versus Lapatinib + Capecitabine in Patients with Previously Treated Metastatic Breast Cancer.

PURPOSE: Neratinib plus capecitabine (N+C) demonstrated significant progression-free survival (PFS) benefit in NALA (NCT01808573), a randomized phase III trial comparing N+C with lapatinib + capecitabine (L+C) in 621 patients with HER2-positive (HER2+) metastatic breast cancer (MBC) who had received ≥2 prior HER2-directed regimens in the metastatic setting. We evaluated correlations between exploratory biomarkers and PFS. PATIENTS AND METHODS: Somatic mutations were evaluated by next-generation sequencing on primary or metastatic samples. HER2 protein expression was evaluated by central IHC, H-score, and VeraTag/HERmark. p95 expression (truncated HER2) was measured by VeraTag. HRs were estimated using unstratified Cox proportional hazards models. RESULTS: Four hundred and twenty samples had successful sequencing: 34.0% had PIK3CA mutations and 5.5% had HER2 (ERBB2) mutations. In the combined patient populations, PIK3CA mutations trended toward shorter PFS [wild-type vs. mutant, HR = 0.81; 95% confidence interval (CI), 0.64-1.03], whereas HER2 mutations trended toward longer PFS [HR = 1.69 (95% CI, 0.97-3.29)]. Higher HER2 protein expression was associated with longer PFS [IHC 3+ vs. 2+, HR = 0.67 (0.54-0.82); H-score ≥240 versus <240, HR = 0.77 (0.63-0.93); HERmark positive vs. negative, HR = 0.76 (0.59-0.98)]. Patients whose tumors had higher HER2 protein expression (any method) derived an increased benefit from N+C compared with L+C [IHC 3+, HR = 0.64 (0.51-0.81); H-score ≥ 240, HR = 0.54 (0.41-0.72); HERmark positive, HR = 0.65 (0.50-0.84)], as did patients with high p95 [p95 ≥2.8 relative fluorescence (RF)/mm2, HR = 0.66 (0.50-0.86) vs. p95 < 2.8 RF/mm2, HR = 0.91 (0.61-1.36)]. CONCLUSIONS: PIK3CA mutations were associated with shorter PFS whereas higher HER2 expression was associated with longer PFS. Higher HER2 protein expression was also associated with a greater benefit for N+C compared with L+C.

Efficacy of Neratinib Plus Capecitabine in the Subgroup of Patients with Central Nervous System Involvement from the NALA Trial.

BACKGROUND: Neratinib has efficacy in central nervous system (CNS) metastases from HER2-positive metastatic breast cancer (MBC). We report outcomes among patients with CNS metastases at baseline from the phase III NALA trial of neratinib plus capecitabine (N + C) versus lapatinib plus capecitabine (L + C). MATERIALS AND METHODS: NALA was a randomized, active-controlled trial in patients who received two or more previous HER2-directed regimens for HER2-positive MBC. Patients with asymptomatic/stable brain metastases (treated or untreated) were eligible. Patients were assigned to N + C (neratinib 240 mg per day, capecitabine 750 mg/m2 twice daily) or L + C (lapatinib 1,250 mg per day, capecitabine 1,000 mg/m2 twice daily) orally. Independently adjudicated progression-free survival (PFS), overall survival (OS), and CNS endpoints were considered. RESULTS: Of 621 patients enrolled, 101 (16.3%) had known CNS metastases at baseline (N + C, n = 51; L + C, n = 50); 81 had received prior CNS-directed radiotherapy and/or surgery. In the CNS subgroup, mean PFS through 24 months was 7.8 months with N + C versus 5.5 months with L + C (hazard ratio [HR], 0.66; 95% confidence interval [CI], 0.41-1.05), and mean OS through 48 months was 16.4 versus 15.4 months (HR, 0.90; 95% CI, 0.59-1.38). At 12 months, cumulative incidence of interventions for CNS disease was 25.5% for N + C versus 36.0% for L + C, and cumulative incidence of progressive CNS disease was 26.2% versus 41.6%, respectively. In patients with target CNS lesions at baseline (n = 32), confirmed intracranial objective response rates were 26.3% and 15.4%, respectively. No new safety signals were observed. CONCLUSION: These analyses suggest improved PFS and CNS outcomes with N + C versus L + C in patients with CNS metastases from HER2-positive MBC. IMPLICATIONS FOR PRACTICE: In a subgroup of patients with central nervous system (CNS) metastases from HER2-positive breast cancer after two or more previous HER2-directed regimens, the combination of neratinib plus capecitabine was associated with improved progression-free survival and CNS outcomes compared with lapatinib plus capecitabine. These findings build on previous phase II and III studies describing efficacy of neratinib in the prevention and treatment of CNS metastases, and support a role for neratinib as a systemic treatment option in the management of patients with HER2-positive brain metastases following antibody-based HER2-directed therapies.

Real-World Molecular Testing and Treatment Patterns in Brazilian Patients with Newly Diagnosed Locally Advanced or Metastatic NSCLC.

OBJECTIVES: To evaluate the molecular testing and treatment patterns in a retrospective cohort of newly diagnosed treatment-naïve patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC). METHODS: This is an observational retrospective cohort study conducted across 10 cancer centers in Brazil. Treatment-naïve patients with locally advanced or metastatic NSCLC were enrolled from January to December 2014. The following data were collected from the medical records of patients from diagnosis until the last record (death, loss to follow-up, or the end of the maximum follow-up period): demographics; medical history; smoking status; disease characteristics; previous treatments; and molecular testing patterns and results. The overall survival (OS) was also estimated. RESULTS: A total of 391 patients from 8 different Brazilian states were included, with a median age of 64.1 years (23.7-98.7), with most patients being males (60.1%). The smoking status of 74.2% of patients was a 'former' or 'current smoker'. Stage IV NSCLC at diagnosis was observed in 82.4% of patients, with 269 of them (68.8%) presenting adenocarcinoma (ADC). Among the stage IV ADC patients, 54.0% were referred for molecular testing. Among the patients with an available epidermal growth factor receptor (EGFR) mutation status, 31 (24.0%) were EGFR-positive. The first-line treatment was a platinum-based chemotherapy for 98 patients (25.1%), while non-platinum-based regimens were used in 54 patients (13.8%). OS data were available for 370 patients, with a median OS of 10.8 months. Never smokers had a significantly higher median OS versus current or former smokers (14.6 versus 9.1 months; log-rank p=0.003). Among the patients for whom molecular testing data were available, those with EGFR-positive results had a longer median OS (34.6 versus 12.8 months; log-rank p=0.003). CONCLUSION: Our findings provide relevant information for prescribers and policy decision-makers by highlighting the unmet needs of patients and the importance of molecular testing in newly diagnosed locally advanced or metastatic lung adenocarcinoma. We also highlight the respective EGFR-tyrosine kinase inhibitor treatment when the result is positive and the areas in which further efforts are required to grant access to effective treatment.

The impact of sociodemographic factors and health insurance coverage in the diagnosis and clinicopathological characteristics of breast cancer in Brazil: AMAZONA III study (GBECAM 0115).

PURPOSE: In Brazil, the available cancer registries are deficient in number and quality and, hence, little information is known regarding sociodemographic, clinicopathological characteristics, treatment patterns, and outcomes of breast cancer (BC) patients. We performed the AMAZONA III/ GBECAM 0115 study and in this analysis, we describe patients' characteristics at diagnosis and their association with health insurance type. METHODS: This is a prospective cohort study developed in 23 sites in Brazil including women with newly diagnosed invasive BC from January 2016 to March 2018. In order to compare healthcare insurance type, we considered patients who were treated under the Brazilian public health system as publicly insured, and women who had private insurance or paid for their treatment as privately insured. RESULTS: A total of 2950 patients were included in the study. Median age at diagnosis was 53.9 years; 63.1% were publicly insured. The majority of patients (68.6%) had stage II-III breast cancer and ductal carcinoma histology (80.9%). The most common breast cancer subtype was luminal A-like (48.0%) followed by luminal B-HER2 positive-like (17.0%) and triple-negative (15.6%). Luminal A was more frequent in private (53.7% vs. 44.2%, p < .0001) than public, whereas Luminal B HER2-positive (19.2% vs. 14.2%, p = 0.0012) and HER2-positive (8.8% vs. 5.1%, p = 0.0009) were more common in patients with public health system coverage. Only 34% of patients were diagnosed by screening exams. Privately insured patients were more frequently diagnosed with stage I disease when compared to publicly insured patients; publicly insured patients had more stage III (33.5% vs. 14.7%; p-value < 0.0001) disease than privately insured ones. Breast cancer was detected by symptoms more frequently in publicly than in privately insured patients (74.2% vs 25.8%, respectively; p-value < 0.0001). CONCLUSIONS: Patients with public health coverage were diagnosed with symptomatic disease, later stages and more aggressive subtypes when compared to privately insured patients.

Advanced Stage at Diagnosis and Worse Clinicopathologic Features in Young Women with Breast Cancer in Brazil: A Subanalysis of the AMAZONA III Study (GBECAM 0115).

PURPOSE: Breast cancer (BC) in young women is uncommon and tends to present with more aggressive characteristics. To better understand and characterize this scenario in Brazil through real-world data, we performed a subanalysis of AMAZONA III study (ClinicalTrials.gov identifier: NCT02663973). METHODS: The AMAZONA III study (GBECAM 0115) is a prospective registry that included 2,950 women newly diagnosed with invasive BC in Brazil from January 2016 until March 2018 at 22 sites. Valid data were obtained from 2,888 patients regarding age at diagnosis and complete baseline information. To compare epidemiologic and clinicopathological features at the time of diagnosis, patients with BC were divided into two groups according to age: ≤ 40 years and > 40 years. Quantitative variables were described as means, and categorical variables were described as frequencies and percentages and compared using the Pearson's χ2 test. RESULTS: Of 2,888 women diagnosed with BC, 486 (17%) were ≤ 40 years old. Young women had higher educational level, most were employed and a significant number were married (P < .001 for all associations). Younger patients were more symptomatic at BC diagnosis (P < .001), and they also presented more frequently with stage III, T3/T4, grade 3 tumors, HER-2-positive, luminal B, and triple-negative subtypes. CONCLUSION: Brazilian women younger than age 40 years have unfavorable clinicopathological features of BC at diagnosis, with more aggressive subtypes and advanced stage when compared with older women. These differences are not explained by socioeconomic or ethnic imbalances. The causes of a higher prevalence of BC among young women in Brazil deserve additional investigation.

Molecular profile of non-small cell lung cancer in northeastern Brazil.

OBJECTIVE: To investigate the histological subtypes and mutational profiles of non-small cell lung cancer in Brazil, looking for correlations among histological subtypes, expression of anaplastic lymphoma kinase (ALK), EGFR mutation status, and programmed death-ligand 1 (PD-L1) expression. METHODS: We evaluated 173 specimens obtained from patients with lung adenocarcinoma in northeastern Brazil. Expression of PD-L1 and ALK was evaluated by immunohistochemistry; EGFR mutation status was evaluated by sequencing. We categorized the histological subtypes in accordance with the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society classification. RESULTS: The most common histological subtypes of lung adenocarcinoma were solid predominant (in 46.8%), acinar predominant (in 37.0%), and lepidic predominant (in 9.8%). ALK expression was detected in 10.4% of the samples, and 22.0% of the tumors harbored EGFR mutations. The most common EGFR mutation was an exon 21 L858R point mutation (in 45.5%), followed by an exon 19 deletion (in 36.3%). The tumor proportion score for PD-L1 expression was ≥ 50% in 18.2% of the samples, 1-49% in 32.7%, and 0% in 49.5%. The solid predominant subtype was significantly associated with wild-type EGFR status (p = 0.047). Positivity for PD-L1 expression was not found to be significantly associated with ALK expression or EGFR mutation status. CONCLUSIONS: Our results suggest that the molecular profile of non-small cell lung cancer in northeastern Brazil differs from those of populations in other regions of the country, with ALK positivity being higher than the other biomarkers. Further studies including clinical and genetic information are required to confirm these differences, as well as studies focusing on populations living in different areas of the country.

The LACOG-0415 phase II trial: abiraterone acetate and ADT versus apalutamide versus abiraterone acetate and apalutamide in patients with advanced prostate cancer with non-castration testosterone levels.

BACKGROUND: Testosterone suppression is the standard treatment for advanced prostate cancer, and it is associated with side-effects that impair patients' quality of life, like sexual dysfunction, osteoporosis, weight gain, and increased cardiovascular risk. We hypothesized that abiraterone acetate with prednisone (AAP) and apalutamide, alone or in combination, can be an effective hormonal therapy also possibly decreasing castration-associated side effects. METHODS: Phase II, open-label, randomized, efficacy trial of abiraterone acetate plus prednisone (AAP) and Androgen Deprivation Therapy (ADT) versus apalutamide versus the combination of AAP (without ADT) and apalutamide. Key eligibility criteria are confirmed prostate adenocarcinoma; biochemical relapse after definitive treatment (PSA ≥ 4 ng/ml and doubling time less than 10 months, or PSA ≥ 20 ng/ml); newly diagnosed locally advanced or metastatic prostate cancer; asymptomatic to moderately symptomatic regarding bone symptoms. Patients with other histology besides adenocarcinoma or previous use of hormonal therapy or chemotherapy were excluded. DISCUSSION: There is an urgent need to study and validate regimens such as new hormonal agents that may add benefit to castration with an acceptable safety profile. We aim to evaluate if apalutamide in monotherapy or in combination with AAP is an effective and safety hormonal treatment that can spare patients of androgen deprivation therapy. TRIAL REGISTRATION: This trial was registered in ClinicalTrials.gov on October 16, 2017, under Identifier: NCT02867020.

RESUMO Objetivo: Investigar os subtipos histológicos e perfis de mutação do carcinoma pulmonar de células não pequenas no Brasil, bem como as correlações entre os subtipos histológicos, a expressão do gene anaplastic lymphoma kinase (ALK, quinase do linfoma anaplásico), o estado de mutação do gene EGFR e a expressão de programmed death-ligand 1 (PD-L1, ligante de morte celular programada 1). Métodos: Avaliamos 173 espécimes provenientes de pacientes com adenocarcinoma pulmonar no Nordeste brasileiro. A expressão de PD-L1 e ALK foi avaliada por meio de imuno-histoquímica, ao passo que o estado de mutação do EGFR foi avaliado por meio de sequenciamento. Os subtipos histológicos foram classificados de acordo com a International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society. Resultados: Os subtipos histológicos mais comuns de adenocarcinoma pulmonar foram o predominantemente sólido (em 46,8%), o predominantemente acinar (em 37,0%) e o predominantemente lepídico (em 9,8%). A expressão de ALK foi detectada em 10,4% das amostras, e 22,0% dos tumores apresentavam mutações do gene EGFR. As mutações mais comuns do EGFR foram a mutação pontual L858R no éxon 21 (em 45,5%) e a deleção do éxon 19 (em 36,3%). O tumor proportion score relativo à expressão de PD-L1 foi ≥ 50% em 18,2% das amostras, = 1-49% em 32,7% e = 0% em 49,5%. O subtipo predominantemente sólido relacionou-se significativamente com EGFR selvagem (p = 0,047). A expressão positiva de PD-L1 não se relacionou significativamente com a expressão de ALK ou o estado de mutação do EGFR. Conclusões: Nossos resultados sugerem que o perfil molecular do carcinoma pulmonar de células não pequenas no Nordeste brasileiro difere do de populações em outras regiões do país: a expressão positiva de ALK é maior que os demais biomarcadores. Mais estudos com informações clínicas e genéticas são necessários para confirmar essas diferenças, além de estudos que se concentrem em populações em diferentes áreas do país.

O uso da internet como fonte de informação sobre cirurgia plástica na Bahia, Brasil / Use of the Internet as a source of information about plastic surgery in Bahia, Brazil", "_e": "n

INTRODUÇÃO: A internet se tornou uma das mais importantes fontes de informação sobre saúde. Poucos estudos avaliam as características do acesso à internet pelos pacientes e a influência das informações obtidas na decisão em realizar uma cirurgia. O objetivo deste estudo é descrever as características do acesso à internet pelos pacientes do Sistema Único de Saúde (SUS) e da rede privada que pretendem se submeter a uma cirurgia plástica, bem como avaliar o impacto do acesso na confiança do paciente em realizar o procedimento. MÉTODO: Realizado estudo observacional de corte transversal com uso de dados coletados por meio de 200 questionários respondidos por pacientes ainda não operados, sendo 100 dirigidos aos pacientes atendidos no ambulatório de Cirurgia Plástica do Hospital Universitário Professor Edgard Santos (SUS) e 100, aos pacientes atendidos em consultório da rede privada de saúde, na cidade de Salvador, BA. RESULTADOS: A frequência do acesso à internet na busca por informação sobre cirurgia plástica foi significativamente diferente entre o SUS (n = 24; 24%) e a rede privada (n = 64; 64%). A maioria dos pacientes (n = 48; 54,5%) acessou um a três sites. Os sites de clínicas de cirurgia plástica foram os mais procurados (n = 74; 84,1%), seguidos pelo site da Sociedade Brasileira de Cirurgia Plástica. Cinquenta por cento dos pacientes afirmaram ter encontrado informações contrárias sobre um mesmo assunto. Ainda assim, 71 (80,7%) dos entrevistados afirmaram se sentir seguros em realizar a cirurgia. CONCLUSÕES: A internet foi significativamente utilizada na busca de informações sobre cirurgia plástica. Independentemente da contradição entre as informações encontradas nos sites, a maioria dos pacientes sentiu-se segura em realizar o procedimento cirúrgico desejado.

BACKGROUND: The Internet has become one of the most important sources of health information. However, few studies have assessed the characteristics of Internet usage by patients or how the information obtained affects decisions to undergo surgery. This study describes the characteristics of Internet usage by patients who intended to undergo plastic surgery at the Unified Health System (SUS) and private networks and how it affected their confidence. METHODS: A cross-sectional observational study was performed using data collected by 200 surveys filled out by patients before the operation. One hundred surveys were sent to patients attending the outpatient clinic of Plastic Surgery of Professor Edgard Santos University Hospital (SUS), and the remaining 100 to patients treated in private health clinics in Salvador, BA. RESULTS: The frequency of Internet use to seek health information on plastic surgery differed significantly between the SUS (n = 24; 24%) and private health services (n = 64; 64%). Most of the patients (n = 48; 54.5%) visited 1 to 3 sites. The websites of plastic surgery centers were the most sought (n = 74; 84.1%), followed by the Brazilian Society of Plastic Surgery website. Half of the patients reported the existence of contradictory information. Moreover, 71 (80.7%) of the respondents reported feeling that undergoing surgery was safe. CONCLUSIONS: The Internet was widely used to seek information on plastic surgery. Although visited sites contained contradictory information, most patients felt safe before undergoing their desired surgery.

Palliative care in poor-performance status small cell lung cancer patients: is there a mandatory role for chemotherapy?

PURPOSE: Small cell lung cancer (SCLC) is an aggressive malignancy but with a high response rate to chemotherapy. Eastern Cooperative Oncology Group performance status (ECOG PS) has been recognized as one of the main prognostic factors in SCLC. There are few data about risk-benefit ratio of chemotherapy over exclusive best supportive care in ECOG PS 3 and 4 patients. This study was performed to assess the outcome of poor ECOG PS SCLC patients that received chemotherapy in our institution. METHODS: A retrospective review of medical records from patients with ECOG PS 3-4 SCLC, who received systemic chemotherapy, was performed between January 2001 and December 2006 at the Instituto Nacional do Câncer, Rio de Janeiro, Brazil. RESULTS: A total of 40 patients were included. Extensive disease was observed in 85% of patients and 25% had PS 4. The median overall survival was 53 days (64 days for ECOG PS 3 and 7 days for ECOG PS 4). There were 30% of early deaths. On univariate analysis, lactate dehydrogenase value, need for hospital admission, and exposure to radiotherapy had impact on survival. ECOG PS 3 patients had better survival than PS 4 patients, even when adjusted for stage. On multivariate analysis, ECOG PS, combined with stage, sustained a major influence on survival. CONCLUSIONS: Median survival for ECOG PS 4 patients treated with chemotherapy in our series was extremely short with a high rate of early deaths. ECOG PS 3 patients also showed a poor survival. These data suggest that we need a more comprehensive approach and further studies, regarding the palliative care of this high-risk population.
