Efficacy of olaparib in advanced cancers with germline or somatic mutations in BRCA1, BRCA2, CHEK2 and ATM, a Belgian Precision tumor-agnostic phase II study. ESMO Open 2023; 8:102041. [PMID: 37852034 PMCID: PMC10774963 DOI: 10.1016/j.esmoop.2023.102041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 09/20/2023] [Accepted: 09/21/2023] [Indexed: 10/20/2023] Open
Abstract
BACKGROUND The Belgian Precision initiative aims to maximize the implementation of tumor-agnostic next-generation sequencing in patients with advanced cancer and enhance access to molecularly guided treatment options. Academic tumor-agnostic basket phase II studies are part of this initiative. The current investigator-driven trial aimed to investigate the efficacy of olaparib in advanced cancers with a (likely) pathogenic mutation (germline or somatic) in a gene that plays a role in homologous recombination (HR). PATIENTS AND METHODS This open-label, multi-cohort, phase II study examines the efficacy of olaparib in patients with an HR gene mutation in their tumor and disease progression on standard of care. Patients with a somatic or germline mutation in the same gene define a cohort. For each cohort, a Simon minimax two-stage design was used. If a response was observed in the first 13 patients, 14 additional patients were included. Here, we report the results on four completed cohorts: patients with a BRCA1, BRCA2, CHEK2 or ATM mutation. RESULTS The overall objective response rate across different tumor types was 11% in the BRCA1-mutated (n = 27) and 21% in the BRCA2-mutated (n = 27) cohorts. Partial responses were seen in pancreatic cancer, gallbladder cancer, endocrine carcinoma of the pancreas and parathyroid cancer. One patient with a BRCA2 germline-mutated colon cancer has an ongoing complete response with 19+ months on treatment. Median progression-free survival in responding patients was 14+ months (5-34+ months). The clinical benefit rate was 63% in the BRCA1-mutated and 46% in the BRCA2-mutated cohorts. No clinical activity was observed in the ATM (n = 13) and CHEK2 (n = 14) cohorts. CONCLUSION Olaparib showed efficacy in different cancer types harboring somatic or germline mutations in the BRCA1/2 genes but not in ATM and CHEK2. Patients with any cancer type harboring BRCA1/2 mutations should have access to olaparib.

UNcommon EGFR Mutations: International Case Series on Efficacy of Osimertinib in Real-Life Practice in First-LiNe Setting (UNICORN). J Thorac Oncol 2023; 18:169-180. [PMID: 36307041 DOI: 10.1016/j.jtho.2022.10.004] [Citation(s) in RCA: 28] [Impact Index Per Article: 28.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 09/10/2022] [Accepted: 10/03/2022] [Indexed: 11/06/2022]
Abstract
INTRODUCTION Approximately 10% of EGFR mutations (EGFRmuts) are uncommon (ucEGFRmuts). We aimed to collect real-world data about osimertinib for patients with ucEGFRmuts. METHODS This is a multicenter, retrospective study of ucEGFRmut (exon 20 insertions excluded) metastatic NSCLC treated with osimertinib as first EGFR inhibitor. The Response Evaluation Criteria in Solid Tumors and response assessment in neuro-oncology brain metastases brain objective response rate (ORR) were evaluated by the investigators. Median progression-free survival (mPFS), median overall survival, and median duration of response (mDOR) were calculated from osimertinib initiation. Mutations found at resistance were collected. RESULTS A total of 60 patients were included (22 centers, nine countries), with median age of 64 years, 75% females, and 83% Caucasian. The largest subgroups were G719X (30%), L861Q (20%), and de novo Thr790Met (T790M) (15%). The ORR was 61%, mPFS 9.5 months, mDOR 17.4 months, and median overall survival 24.5 months. Regarding patients with no concurrent common mutations or T790M (group A, n = 44), ORR was 60%, mPFS 8.6 months, and mDOR 11 months. For G719X, ORR was 47%, mPFS 8.8 months, and mDOR 9.1 months. For L861Q, ORR was 80%, mPFS 16 months, and mDOR 16 months. For de novo T790M, ORR was 44%, mPFS 12.7 months, and mDOR 46.2 months. Compound EGFRmut including common mutations had better outcome compared with only ucEGFRmut. For 13 patients with a response assessment in neuro-oncology brain metastases-evaluable brain metastases, brain ORR was 46%. For 14 patients, rebiopsy results were analyzed: four patients with additional EGFR mutation (C797S, D585Y, E709K), three with new TP53 mutation, one with c-Met amplification, one with PIK3CA mutation, and one with neuroendocrine transformation. CONCLUSIONS Osimertinib was found to have an activity in ucEGFRmut with a high rate of disease control systemically and intracranially. Several resistance mechanisms were identified. This report comprises, to the best of our knowledge, the largest data set of its kind.

Abstract
PRECISION is an initiative from the Belgian Society of Medical Oncology (BSMO) in collaboration with several stakeholders, encompassing four programs that aim to boost genomic and clinical knowledge with the ultimate goal to offer patients with metastatic solid tumors molecularly guided treatments. The PRECISION 1 study has led to the creation of a clinico-genomic database. The Belgian Approach for Local Laboratory Extensive Tumor Testing (BALLETT) and GeNeo studies will increase the number of patients with advanced cancer that have comprehensive genotyping of their cancer. The PRECISION 2 project consists of investigator-initiated phase II studies aiming to provide access to a targeted drug for patients whose tumors harbor actionable mutations in case the matched drug is not available through reimbursement or clinical trials in Belgium.

Abstract
9109 Background: About 10% of EGFR mutations (EGFRm) are ‘uncommon mutations’ (ucEGFRm). osimertinib is a 3rd generation EGFRi, active against common EGFRm. We aimed to collect real-world data about systemic and brain response and resistance mechanisms to osimertinib for ucEGFRm patients. Methods: This is a multi-center, retrospective study of ucEGFRm mNSCLC treated with osimertinib as first EGFRi. RECIST and RANO-BM response was evaluated by investigators. Progression free survival (PFS), overall survival (OS) and duration of response (DOR) were calculated from initiation of osimertinib. Mutations found at resistance were collected. Results: 62 patients (pts) were identified in 22 centers from 9 countries. Median age was 64 (35-91) years, 74% females, 84% Caucasian, never/former/current smokers were 48%/39%/11% respectively, ECOG PS was 0-1/2/3-4 in 84%/10%/5%. Histology was adenocarcinoma in 97%. The largest subgroups were G719X, de novo T790M and L861Q (Table). Compound EGFR mutations were found in 27 pts (44%), TP53 mutations in 21 pts (34%). In 17 cases (27%), compound mutations included the common L858R/deletion19 and/or de novo T790M. Most frequent metastatic sites were lung/bone/brain in 45%/44%/39%. Most frequent toxicities were gastrointestinal (32 pts, 52%) and skin (24 pts, 39%); 8 pts had grade 3-4 AEs. No grade 5 AE occurred. 3 pts had AEs leading to discontinuation. RECIST response (RR) was available for 53 pts, CR - 4 (8%), PR - 27 (51%), SD - 17 (32%), and PD - 5 (9%). Median DOR (mDOR) was 17.4 months (95% CI 9.1-NA). mPFS was 9.5 months (95% CI 8.5–17.4). mOS was 24.5 months (95% CI 17.4-35.1). See Table for efficacy in the major subgroups. 24 pts (39%) had brain metastasis at presentation, for 12 pts a brain response by RANO-BM was available with 25%/25%/33%/17% CR/PR/SD/PD. For 14 pts, rebiopsy mutation analysis at progression on osimertinib was available: 3 pts with an additional EGFR mutation (C797S,D585Y, E709K), 3 pts with a new TP53 mutation, 1 with c-Met amplification and 1 pt with transformation to neuroendocrine carcinoma. Conclusions: Osimertinib demonstrated activity in ucEGFRm with 91% disease control rate and encouraging PFS and DOR. Brain response was seen in 50% of cases. Several resistance mechanisms were identified. This report comprises, to the best of our knowledge, the largest dataset of osimertinib as the first EGFRi for ucEGFRm presented so far.

Azithromycin for Treatment of Hospitalised COVID-19 Patients: a randomised, multicentre, open-label clinical trial (DAWn-AZITHRO). ERJ Open Res 2022; 8:00610-2021. [PMID: 35233389 PMCID: PMC8801156 DOI: 10.1183/23120541.00610-2021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Accepted: 12/28/2021] [Indexed: 12/23/2022] Open
Abstract
Background and objectives Azithromycin was rapidly adopted as a repurposed drug to treat coronavirus disease 2019 (COVID-19) early in the pandemic. We aimed to evaluate its efficacy in patients hospitalised for COVID-19. Methods In a series of randomised, open-label, phase 2 proof-of-concept, multicentre clinical trials (Direct Antivirals Working against the novel coronavirus (DAWn)), several treatments were compared with standard of care. In 15 Belgian hospitals, patients hospitalised with moderate to severe COVID-19 were allocated 2:1 to receive standard of care plus azithromycin or standard of care alone. The primary outcome was time to live discharge or sustained clinical improvement, defined as a two-point improvement on the World Health Organization (WHO) ordinal scale sustained for at least 3 days. Results Patients were included between April 22 and December 17, 2020. When 15-day follow-up data were available for 160 patients (56% of preset cohort), an interim analysis was performed at request of the independent Data Safety and Monitoring Board. Subsequently, DAWn-AZITHRO was stopped for futility. In total, 121 patients were allocated to the treatment arm and 64 patients to the standard-of-care arm. We found no effect of azithromycin on the primary outcome with a hazard ratio of 1.044 (95% CI 0.772–1.413; p=0.7798). None of the predefined subgroups showed significant interaction as covariates in the Fine–Gray regression analysis. No benefit of azithromycin was found on any of the short- and longer-term secondary outcomes. Conclusion Time to clinical improvement is not influenced by azithromycin in patients hospitalised with moderate to severe COVID-19. Previous randomised controlled studies with azithromycin in hospitalised COVID-19 patients assessed end-points at fixed timepoints. Complementary to this, DAWn-AZITHRO assessed time to sustained improvement. No benefit of azithromycin was shown.https://bit.ly/3FapyC7

Abstract
Gastric (G) and gastro-esophageal junction (GEJ) adenocarcinomas are of the most common and deadly cancers worldwide and affect mainly patients over 70 years at diagnosis. Older age has been associated in gastric cancers with distal tumour location, well-differentiated adenocarcinoma and microsatellite instability and is not identified itself as an independent prognostic factor. As immune checkpoint inhibitors recently changed the landmark of advanced G and GEJ adenocarcinomas treatment, we decided to perform a literature review to define the evidence-level of clinical data in older patients. This work underlined the lasting low -inclusion rate of older patients and -implementation rate of frailty screening tools in clinical trials in G/GEJ carcinomas. In the first-line metastatic setting, two prospective randomized phase III studies have specifically assessed the efficacy of chemotherapy in older patients with HER2-negative gastric cancers, demonstrating the feasibility of reduced dose oxaliplatin-based chemotherapy regimen in this population. Only few data are available in HER2-positive tumors, or in the second-line setting. Furthermore, no specific trial with immune checkpoint inhibitors was performed in older frail patients whereas their benefit/adverse events ratio make them attractive candidates in this patient's population. We conclude that older fit patients can be treated in the same way as younger ones and included in clinical trials. Improving the outcome of older frail patients should be the oncology community next focus by implementing targeted interventions before initiating cancer therapy and designing specific clinical trials. Frailty screening tools and geriatric data collection have to be implemented in routine-practice and clinical trials.

Abstract
Background In the general older population, geriatric assessment (GA)-guided treatment plans can improve overall survival, quality of life and functional status (FS). In GA-related research in geriatric oncology, studies mainly focused on geriatric screening and GA but not on geriatric recommendations, interventions and follow-up. The aim of this study was to investigate the adherence to geriatric recommendations and subsequent actions undertaken in older patients with cancer. Patient and methods A prospective Belgian multicenter (N = 22) cohort study included patients ≥70 years with a malignant tumor upon oncologic treatment decision. Patients with an abnormal result on the geriatric screening (G8 ≤14/17) underwent GA. Geriatric recommendations were formulated based on GA results. At follow-up the adherence to geriatric recommendations was documented including a description of actions undertaken. Results From November 2012 till February 2015, G8 screening was carried out in 8451 patients, of which 5838 patients had an abnormal result. Geriatric recommendations data were available for 5631 patients. Geriatric recommendations were made for 4459 patients. Geriatric interventions data were available for 4167 patients. A total of 12 384 geriatric recommendations were made. At least one different geriatric recommendation was implemented in 2874 patients. A dietician, social worker and geriatrician intervened most frequently for problems detected on the nutritional, social and functional domain. A total of 7569 actions were undertaken for a total of 5725 geriatric interventions, most frequently nutritional support and supplements, extended home care and psychological support. Conclusions This large-scale Belgian study focuses on the adherence to geriatric recommendations and subsequent actions undertaken and contributes to the optimal management of older patients with cancer. We identified the domains for which geriatric recommendations are most frequently made and adhered to, and which referrals to other health care workers and facilities are frequently applied in the multidisciplinary approach of older patients with cancer.

Abstract
Abstract
Background: BSMO 2014-01 is a completed prospective phase 2 study evaluating the efficacy of neoadjuvant EC and PC. One of the secondary endpoints was the correlation of sTIL with response, pCR and survival. We also assessed the relationship between sTIL and TLS in the diagnostic biopsies.
Methods: Stromal TIL (sTIL) were evaluated on H&E stained tumor biopsies before the start of the NAC according to the criteria described by Salgado et al(1). Scores were defined as "low" or "high" if lymphocytic infiltration in the stroma around the tumor was ≤ 10% or > 10%. TLS are ectopic lymph node-like structures recently identified in breast cancer. TLS were counted using a dual IHC stain for CD3 (T cells) and CD20 (B cells) and categorized as "little" if the TLS occupied < 10% or "moderate to abundant" if they occupied ≥ 10% of the adjacent tissue. The correlation between sTIL and pathologic parameters was analyzed using the chi-square test; DFS and OS between the groups was estimated by using the log-rank test.
Results: So far we could quantify the number of sTIL in 38 out of 63 TNBC pts treated with neoadjuvant EC-PC. Twenty eight pts had a high sTIL score and 10 pts had a low sTIL score. The high-sTIL group (19/28) achieved a numerical higher pathologic complete remission (pCR) rate than the low-sTIL group (5/10) (p=0.3); both groups had a comparable disease free survival of 28.6 mths and 26.7 mths respectively (p=0.7). The overall survival was similar:29 mths and 27.8 mths respectively (p=0.8). Stromal TLS were identified in 10 out 23 samples available for this analysis and we could demonstrate a positive correlation between high levels of sTIL and high levels of moderate to abundant TLS(CD3) in the adjacent tissue in six out of the ten samples in which TLS were present (p=0.1).
Conclusion: These preliminary results could not confirm the results published by Denkert et al earlier this year(2). A trend for correlation of the presence of high sTIL with moderate to abundant levels of TLS was found. Analysis on the remaining samples of all patients included in the study and correlation with outcome is ongoing and these completed results will be presented.

Abstract
PURPOSE Using the EORTC Global Health Status (GHS) scale, we aimed to determine minimal clinically important differences (MCID) in health-related quality of life (HRQOL) changes for older cancer patients with a geriatric risk profile, as defined by the geriatric 8 (G8) health screening tool, undergoing treatment. Simultaneously, we assessed baseline patient characteristics prognostic for HRQOL changes. METHODS Our analysis included 1424 (G8 ≤ 14) older patients with cancer scheduled to receive chemotherapy (n = 683) or surgery (n = 741). Anchor-based methods, linking the GHS score to clinical indicators, were used to determine MCID between baseline and follow-up at 3 months. A threshold of 0.2 standard deviation (SD) was used to exclude MCID estimates too small for interpretation. Logistic regressions analysed baseline patient characteristics prognostic for HRQOL changes. RESULTS The 15-item Geriatric Depression Scale (GDS15), Visual Analogue Scale (VAS) for Fatigue and ECOG Performance Status (PS) were selected as clinical anchors. In the surgery group, MCID estimates for improvement and deterioration were ECOG PS (5*, 11*), GDS15 (5*, 2) and VAS Fatigue (3, 9*). In the chemotherapy group, MCID estimates for improvement and deterioration were ECOG PS (8*, 7*), GDS15 (5, 4) and VAS Fatigue (5, 5*). Estimates with * were > 0.2 SD threshold. Patients experiencing pain or malnutrition (surgery group) or fatigue (chemotherapy group) at baseline showed a significantly stable or improved HRQOL (p < 0.05) after their treatment. CONCLUSION The reported MCID for improvement and deterioration depended on the anchor used and treatment received. The estimates can be used to evaluate significant changes in HRQOL and to determine sample sizes in clinical trials.

Abstract
PURPOSE Older patients with lung cancer are a heterogeneous population making treatment decisions complex. This study aims to evaluate the value of geriatric assessment (GA) as well as the evolution of functional status (FS) in older patients with lung cancer, and to identify predictors associated with functional decline and overall survival (OS). METHODS At baseline, GA was performed in patients ≥70 years with newly diagnosed lung cancer. FS measured by activities of daily living (ADL) and instrumental activities of daily living (IADL) was reassessed at follow-up to define functional decline and OS was collected. Predictors for functional decline and OS were determined. RESULTS Two hundred and forty-five patients were included in this study. At baseline, GA deficiencies were present in all domains and ADL and IADL were impaired in 51 and 63% of patients, respectively. At follow-up, functional decline in ADL was observed in 23% and in IADL in 45% of patients. In multivariable analysis, radiotherapy was predictive for ADL decline. No other predictors for ADL or IADL decline were identified. Stage and baseline performance status were predictive for OS. CONCLUSIONS Older patients with lung cancer present with multiple deficiencies covering all geriatric domains. During treatment, functional decline is observed in almost half of the patients. None of the specific domains of the GA were predictive for functional decline or survival, probably because of the high impact of the aggressiveness of this tumor type leading to a poor prognosis.

Abstract
Abstract
Introduction: Triple negative breast cancer (TNBC) remains a challenging disease with dismal prognosis. Platinum analogs have not yet shown to improve long term outcome in this setting, but are associated with increased pathological complete response rate (pCR) at the cost of higher toxicity.
Aim: To further increase or maintain the high pCR rate with platinum containing schedules while decreasing toxicity by administering low dose weekly carboplatin instead of high-dose 3 weekly carboplatin as in CALGB 40603.(1)
Patients and methods: We evaluated the tolerability and the impact of the addition of weekly carboplatin (CP) to paclitaxel (P) and dose dense epirubicin-cyclofosfamide (EC) on pCR in an open-label multicenter phase II study in stage II/III TNBC patients (pts). Sixty three pts received dose dense paclitaxel (P:80mg/m2/wk) concurrent with carboplatin (CP: AUC=2) for 12 wks, followed by two-weekly epirubicin (E:90mg/m2) and cyclophosphamide (C:600mg/m2) for 4 cycles. The primary endpoint is pCR in the breast and axilla. Additionally treatment deliveryand adverse events are recorded. A correlative assessment of germline mutations in homologous recombination (HR) genes is planned. Pts are monitored for response by magnetic resonance and mammography and also for relapse free survival and time to treatment failure. The study size sample has been calculated according to the optimal Simon's two-stage design method. The target sample size was 63 patients with 80% power to detect a pCR rate of ≥47% (α= 0.05).
Results: Accrual to the study is completed with 63 eligible pts with operable, noninflammatory stage II and III TNBC included. Most patients were between 40 and 60 yrs old and were clinical stageT2 tumors. Half of the pts were clinically node + and 70% were G3. Sixty six percent had breast conserving surgery. Sixteen out of 26 (61.5%) of the currently evaluable pts achieved a pCR rate in the breast and axilla. The other ongoing patients have not yet reached this endpoint. Four out of 21 evaluable pts that completed the chemotherapy missed two or more doses of CP due to neutropenia(NP) G3/4(2), general deterioration G3(1) and polyneuropathy(PNP) G3(1) and seven pts needed one dose reduction of P and/or CP due to NP G3-4 (3-2) and PNP G2(1) and one abdominal infection.
Conclusion: These preliminary data suggest that the addition of weekly carboplatinum to neoadjuvant paclitaxel and EC is feasible and has a promising pCR rate in the breast and axilla as high as 61.5% in early TNBC pts. More mature toxicity and outcome data and correlation with genome analysis will be presented.

Abstract
Abstract
Background:
Ten to 20% percent of all breast cancers occur in a familial context and in 20-30% of these cases a mutation in the BRCA1 or BRCA2, CHEK2 genes or, more rarely, in PALB2 can be found. The remaining cases remain routinely undiagnosed with regard to a possible genetic cause.
We have examined a cohort of undiagnosed probands using exome germline sequencing in order to identify other potential breast cancer predisposition genes.
Methods:
In total, 63 BRCA1/2-negative high risk familial BC cases (BRCAX) were considered for pair-end whole exome germline DNA sequencing on a HiSeq1500 (Illumina). High quality reads were mapped (BWA-MEM) to the reference genome (hg19) and variants were called according to GATK best practice guideline. The variants detected within the panel of 372 cancer associated genes were annoted with ANNOVAR. Synonymous variant as well as variants with MAF>1% were discarded. In a first phase protein truncating variants were validated using another NGS method. Subsequent validation of non-synonymous missense mutations and non-frameshift indels is planned. Patients signed a multilayered informed consent also covering disclosure or not of different types of incidental findings.
Results:
For each exome, the mean breath of coverage was about 96 % at 10X or more and the mean depth of coverage for targeted region was about 126X. In total, 3570709 SNPs (∼56678 SNPs/sample) and 477801 INDELs (7584 INDELs/sample) were called. Of them, 20829 SNPs (331 SNPs/sample) and 16071 INDELs (255 INDELs/sample) passed quality filter. In total, 445 variants were found in the publicly available cancer genes panel. Twenty-seven stop-gain/loss, frame-shift insertion/deletion and splice site variants were considered for validation with 454 Roch Junior, among which 22 variants in genes ABCC11, AFP, BARD1, BBS10, CD96, CYP1A1, DNAH11, ESCO2, EXO1, FANCI, FLCN, FLT4, HPS6, MYH8, NME8, PALB2, PDE11A, RECQL4, TTC8 were validated as true positive. Some of these genes have been found earlier to be associated with breast cancer and/other cancer types. Functional prioritization of the remaining 416 non-synonymous and non-frameshift insertion/deletions was also done in-silico before further sequencing validation, which is ongoing. The mutations found are further clinically validated by examining other affected and non-affected family members and mining the literature. Some of the mutations in known cancer predisposing genes are considered for prudent application in clinical counseling. Genotype-phenotype correlations are being examined.
Conclusion:
Next-generation sequencing enabled us to detect variants with high/low penetrance in known cancer predisposing genes in > 35% of BRAX families, in addition to many novel variants in many other genes not yet tied to cancer predisposition occurring singly or in combination with known cancer gene mutations. Validated variants are further examined in the families for co-segregation with the disease and potential application in counseling.

Abstract
OBJECTIVES The aim of this study is to describe a large-scale, Belgian implementation project about geriatric assessment (=GA) in daily oncology practice and to identify barriers and facilitators for implementing GA in this setting. Design / setting / participants: The principal investigator of every participating hospital (n=22) was invited to complete a newly developed questionnaire with closed- and open-ended questions. The closed-ended questions surveyed how GA was implemented. The open-ended questions identified barriers and facilitators for the implementation of GA in daily oncology practice. Descriptive statistics and conventional content analysis were performed as appropriate. RESULTS Qualifying criteria (e.g. disease status and cancer type) for GA varied substantially between hospitals. Thirteen hospitals (59.1%) succeeded to screen more than half of eligible patients. Most hospitals reported that GA data and follow-up data had been collected in almost all screened patients. Implementing geriatric recommendations and formulating new geriatric recommendations at the time of follow-up are important opportunities for improvement. The majority of identified barriers were organizational, with high workload, lack of time or financial/staffing problems as most cited. The most cited facilitators were all related to collaboration. CONCLUSION Interventions to improve the implementation of GA in older patients with cancer need to address a wide range of factors, with organization and collaboration as key elements. All stakeholders, seeking to improve the implementation of GA in older patients with cancer, should consider and address the identified barriers and facilitators.

Abstract
BACKGROUND Screening tools are proposed to identify those older cancer patients in need of geriatric assessment (GA) and multidisciplinary approach. We aimed to update the International Society of Geriatric Oncology (SIOG) 2005 recommendations on the use of screening tools. MATERIALS AND METHODS SIOG composed a task group to review, interpret and discuss evidence on the use of screening tools in older cancer patients. A systematic review was carried out and discussed by an expert panel, leading to a consensus statement on their use. RESULTS Forty-four studies reporting on the use of 17 different screening tools in older cancer patients were identified. The tools most studied in older cancer patients are G8, Flemish version of the Triage Risk Screening Tool (fTRST) and Vulnerable Elders Survey-13 (VES-13). Across all studies, the highest sensitivity was observed for: G8, fTRST, Oncogeriatric screen, Study of Osteoporotic Fractures, Eastern Cooperative Oncology Group-Performance Status, Senior Adult Oncology Program (SAOP) 2 screening and Gerhematolim. In 11 direct comparisons for detecting problems on a full GA, the G8 was more or equally sensitive than other instruments in all six comparisons, whereas results were mixed for the VES-13 in seven comparisons. In addition, different tools have demonstrated associations with outcome measures, including G8 and VES-13. CONCLUSIONS Screening tools do not replace GA but are recommended in a busy practice in order to identify those patients in need of full GA. If abnormal, screening should be followed by GA and guided multidisciplinary interventions. Several tools are available with different performance for various parameters (including sensitivity for addressing the need for further GA). Further research should focus on the ability of screening tools to build clinical pathways and to predict different outcome parameters.

Abstract
Abstract
Introduction: Nine randomized trials in early breast cancer(EBC) have demonstrated an advantage of aromatase inhibitors(AI’s) over tamoxifen in disease-free survival. Joint symptoms are common toxicities and lead to treatment interruption in up to 20% in case of severe aromatase-induced arthralgia(AIA). During menopause levels of markers of inflammation such as IL-1b, TNF-alpha and IL-6 increase. We hypothesized that estrogen deprivation by aromatase inhibition could be associated with similar changes in these markers and that this could play a role in AIA. In an earlier study, similar toxicities were observed in patients(pts) treated with a recombinant form of IL-6. In several cell types it has been shown that ligand activated estrogen receptor blocks nuclear factor kappa beta controlled gene transcription of IL-6.
Aim of the study: We initiated a prospective open-label study to examine the role of inflammatory cytokines and other serum markers(CRP and hormones) in the pathogenesis of AIA.
Methods: 29 evaluable postmenopausal pts with hormone sensitive, Her 2 negative EBC stage I-III, with baseline G0-1 arthralgia were included. Before chemotherapy, at baseline, at month 3, 6, 9, 12 and 18 after AI initiation, serum samples were taken for CRP and hormones (estradiol, androstenedion) and cytokines were analyzed with a human cytokine 25-plex panel. A detailed rheumatologic questionnaire and Visual Analog Scale(VAS) was performed at each visit. Arthralgia grading was assessed using the CTCAE criteria 4.0. The T-test and the Wilcoxon Signed Rank test were used to look for the difference in terms of IL-6, Il-1b, IL-8, TNF, CRP, estradiol and androstenedion between G0 versus G1-2-3 arthralgia.
Results: The mean age was 56 yrs. (34-72yrs). All patients were treated with surgery followed by concomitant chemoradiation and letrozole (31) or anastrazole (1). In 16 pts G1 arthralgia was present before the start of the chemotherapy. Grade 2 and 3 arthralgia appeared at mth 3. The proportion of pts with grade 2 remained more or less the same, while grade 3 pts declined from month 6 onwards and disappeared at month 18.
Grade of arthralgia at different time pointsArthralgiamth omth 3mth 6mth 9mth 12mth 18G045231911618G1553954615955G202319222927G30158560
There was a significant correlation between the grade of arthralgia and the VAS score at all-time points (p<0.05). CRP levels were significantly higher in the patients with arthralgia at month 3 (p<0.001) and 6 (p<0.005). Patients with G2-3 arthralgia had higher estradiol levels at mth 3 (p<0.001) and 6 (p<0.001).Cytokine results are currently available for the first 12 patients only. In these preliminary data, IL-6 levels were significant higher in the pts with arthralgia before initiation of AI ‘s. The examination of correlations during AI treatment needs the analysis of the full cohort.
Conclusion: This study indicates that both menopause and AIA have inflammatory mediators (IL6 and CRP) that correlate with the degree of lowering of estradiol levels. This is consistent with the regulation of IL-6 by the ligand activated ER through NFkB in vitro.

Abstract
Abstract
Introduction: Aromatase inhibitors (AI) are a well-established component of the adjuvant hormonal therapy in postmenopausal (PM) EBC patients (pts). AI have been associated with joint symptoms in 20 to 40% of pts adversely affecting quality of life and compliance. The subjective nature of these toxicities warrants objective correlates. In this study we have compared synovial changes on MRI with ultrasound (US).
Aim of the study: The primary aim was to assess joint changes in PM EBC pts by MRI and US at baseline and at occurrence of arthralgia G3 during AI therapy. The secondary aim was to investigate the relationship between clinical severity of articular symptoms and markers of bone metabolism.
Methods: PM EBC pts, stages I-III, with a grade 0, 1 arthralgia (CTCAE version 4.0) at baseline were recruited for the study. At baseline and at 3, 6, 9, 12 and 18 months (mths) a rheumatologic questionnaire was performed. At the same time points serum samples for bone markers (Ca, ostase, intact PTH, alkaline phosphatase and vit. D), rheumatoid factor (RF) and urine samples for urinary N-telopeptide (uNTX) were taken. Pain was assessed by the Visual Analog Scale (VAS). Before start of AI, osteoarthritis was quantified by plain radiography (hands, wrists and knees), joint changes were assessed baseline and at occurrence of arthralgia G3 by MRI and US (hands and wrists), and bone density by DEXA.
Results: 29 evaluable PM EBC pts were included in the study. At baseline, 60% of the pts had a mean VAS score of 2 (0/10-5/10), which increased to 2.5 after the adjuvant chemotherapy and to 4.5 (0-8) at mth 12 (p = 0.013) of AI therapy, and subsequently dropped to 2.5 at mth 18 (p = 0.2). The most commonly affected joints at baseline were knees (47%), shoulders (41%), and ankles/feet (29%); whereas during AI therapy it involved mainly knees (53%), shoulders (46%) and hands/wrists (32%). Fifty percent of the pts had signs of osteoarthritis of the hands (25%), knees (16%) and both (8%) on plain radiographs obtained at baseline. Grade 0-1 arthralgia was not significantly correlated with the imaging of osteoarthritis or grade of osteoporosis. At baseline intra-articular fluid was detected on MRI of the hands/wrists in 6 pts, 14 pts had synovial changes and 4 had both. Six out of 29 pts had also signs of synovitis with hyperaemia on US before the start of an AI. G3 arthralgia occurred in five pts of which only three agreed to the repeat radiological imaging. In two of these pts a worsening of imaging both by MRI and US was observed, whereas in the third pt imaging was unchanged.
Markers of bone metabolism and uNTX did not differ significantly between groups with arthralgia and without (p>0.05). RF was positive in only two pts, one with arthralgia G1 at baseline and one pt at the moment of G3 arthralgia.
Conclusions: This study is the first to prospectively report on synovial changes by combined MRI and US before initiation of adjuvant AI in PM women and at occurrence of arthralgia G3. Only 17% of pts developed G3 arthralgia which corresponded to worsening imaging signs. From the small sample size it seems that baseline MRI changes predicts the development of G3 arthralgia with higher sensitivity than baseline US. Sensitivity of US improved during AI therapy.

Abstract
BACKGROUND To evaluate the large-scale feasibility and usefulness of geriatric screening and assessment in clinical oncology practice by assessing the impact on the detection of unknown geriatric problems, geriatric interventions and treatment decisions. PATIENTS AND METHODS Eligible patients who had a malignant tumour were ≥70 years old and treatment decision had to be made. Patients were screened using G8; if abnormal (score ≤14/17) followed by Comprehensive Geriatric Assessment (CGA). The assessment results were communicated to the treating physician using a predefined questionnaire to assess the topics mentioned above. RESULTS One thousand nine hundred and sixty-seven patients were included in 10 hospitals. Of these patients, 70.7% had an abnormal G8 score warranting a CGA. Physicians were aware of the assessment results at the time of treatment decision in two-thirds of the patients (n = 1115; 61.3%). The assessment detected unknown geriatric problems in 51.2% of patients. When the physician was aware of the assessment results at the time of decision making, geriatric interventions were planned in 286 patients (25.7%) and the treatment decision was influenced in 282 patients (25.3%). CONCLUSION Geriatric screening and assessment in older patients with cancer is feasible at large scale and has a significant impact on the detection of unknown geriatric problems, leading to geriatric interventions and adapted treatment.

Clinical activity of afatinib (BIBW 2992) in patients with lung adenocarcinoma with mutations in the kinase domain of HER2/neu. Lung Cancer 2012; 76:123-7. [PMID: 22325357 DOI: 10.1016/j.lungcan.2012.01.008] [Citation(s) in RCA: 229] [Impact Index Per Article: 19.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2011] [Revised: 01/13/2012] [Accepted: 01/15/2012] [Indexed: 12/15/2022]
Abstract
Human epidermal growth factor receptor (HER)2/neu kinase domain mutations are found in approximately 1-4% of lung adenocarcinomas with a similar phenotype to tumors with epidermal growth factor receptor (EGFR) mutations. Afatinib is a potent irreversible ErbB family blocker. We determined the tumor genomic status of the EGFR and HER2 genes in non- or light smokers with lung adenocarcinoma in patients who were entered into an exploratory Phase II study with afatinib. Five patients with a non-smoking history and metastatic lung adenocarcinomas bearing mutations in the kinase domain of HER2 gene were identified, three of which were evaluable for response. Objective response was observed in all three patients, even after failure of other EGFR- and/or HER2-targeted treatments; the case histories of these patients are described in this report. These findings suggest that afatinib is a potential novel treatment option for this subgroup of patients, even when other EGFR and HER2 targeting treatments have failed.

Docetaxel in the treatment of metastatic castration-resistant prostate cancer (mCRPC): an observational study in a single institution. Anticancer Res 2012; 32:633-641.

Abstract
BACKGROUND Treatment with docetaxel in combination with prednisone is the standard first-line treatment in patients with metastatic castration-resistant prostate cancer (mCRPC). For patients failing first-line docetaxel no standard has emerged. OBJECTIVES The outcome in routine daily clinical practice of a cohort of unselected chemotherapy-naïve mCRPC patients treated with docetaxel plus methylprednisolone as first- and further-line treatment in a single institution was investigated. PATIENTS AND METHODS Data from the medical records of patients treated with docetaxel plus methylprednisolone either in a three-weekly (75 mg/m(2)) (D3) or a three-of-four-weekly (35 mg/m(2))(D1) schedule as first- or further-line treatment were analysed with respect to clinical and prostate-specific antigen (PSA) response, time-on-treatment (TOT), treatment-free interval (TFI), overall survival time (OS) and toxicity and were compared to the results of the registration study TAX 327. RESULTS Out of 41 patients, 28 and 13 received first-line docetaxel according to the D3 and the D1 schedules respectively. An overall PSA response ≥50% was achieved in thirty patients (73%). In ten patients (24%) the PSA level was normalised. The median OS of the total population was 18.7 months. No significant differences were observed between the D3 and the D1 regimens with respect to PSA response, duration of PSA response, TOT, TFI and OS. Patients obtaining a normalisation of PSA level achieved a significantly superior OS, TOT and TFI compared to those without normalisation of PSA. Second-line treatment with docetaxel in nine patients induced a normalisation in PSA level in two (22%). The TOT and TFI from the start of second-line treatment, was significantly superior in docetaxel compared to non-docetaxel treated patients. Treatment with docetaxel was well-tolerated and only two patients were withdrawn for non-haematological toxicity during first- and further-line treatment. There were no differences in either subjective or objective side-effects between both treatment schedules. CONCLUSION The results of the retrospective analysis of non-selected patients with mCRPC treated with docetaxel chemotherapy are in line with the data from TAX 327. Normalisation of PSA during first-line treatment with docetaxel is associated with a better survival irrespective of second- or further-line treatment used. Retreatment with docetaxel in second- or further-line remains a treatment option in docetaxel-sensitive patients.

Abstract
Abstract
Introduction/Aim: Adjuvant treatment with aromatase inhibitors (AI) is associated with accelerated bone loss and increase in lipid levels. The effectiveness and tolerance of extended treatment with AI beyond 5 years is currently under investigation. In the SOLE study, five years of continuous (C) extended letrozole is compared to interrupted therapy (9 months on, 3 months off letrozole) after 5 yrs of tamoxifen, AI or sequential hormonal therapy. We have evaluated the bone mineral density and lipid levels during the extended use of letrozole beyond 5 yrs in a cohort of patients included in the SOLE study.
Patients and methods: Postmenopauzal women with HR+ BC, receiving extended continuous (C) or intermittent (I) letrozole for 5 yrs after 5 yrs of tamoxifen, 5 yrs of an AI, or switch therapy within the first 5 years, were included. Bone mineral density was measured at the lumbar spine (L2-4) and total hip BMD (g/cm2), by dual energy X-ray absorptiometry (DXA). The mean percentage change in BMD at 12, 36 and 60 months (mths) was compared between the C and I treatment with letrozole and with baseline values. Differences between the treatment groups were assessed by the independent samples T test. We also compared the evolution ofthe serum lipid levels in both arms. Results: Thirty two patients (pts) were included with a mean age of 62 yrs (+/− 8.7 yrs). Thirty pts were valuable because of missing baseline DXA values in 2. In their first 5 years of adjuvant letrozole, prior to inclusion in the current study, twenty three pts had a mean percentage decrease of −0,76 (13,25 SD) and 7 pts who had received preventive zoledronate in the ZOFAST study, had a mean percentage increase in BMD of 4,4 (6,08 SD).
Currently 12 pts receiving the continuous letrozole are evaluable after a first one year extension of adjuvant letrozole. They had a mean percentage increase in BMD for the lumbar spine of 1.8 (3.3 SD), and a mean percentage increase in BMD for the hip of 0.85 (SD 1.93). Eight pts included in the intermittent arm are evaluable. They experience a mean percentage decrease in BMD for the lumbar spine of −0.32(2.7 SD) and a mean decrease in BMD for the hip of −2.9(SD 3.6) The difference between the two treatment groups was not significant for the lumbar spine measurements (p=0.14), but it was significant for the hip (p=0.02). The mean fasting cholesterol levels at 12 months in the C arm (12pts) was 228mg/dl (24.4 SD) and in the I arm (11pts) was 225,5mg/dl(32,3 SD) (p=0.37).
Conclusion: This is the first prospective BMD and lipid follow-up study during adjuvant letrozole extended beyond 5 yrs in PM early breast cancer pts. After the first year of extended intake of continuous or intermittent letrozole a possible difference in bone mineral density between the two arms is emerging, but the two groups are too small to make final conclusions. An updated longer follow-up on more patients will be presented. After one year no differential effect on cholesterol levels has been observed.

Abstract
The historical results of cancer vaccination for non-small-cell lung cancer (NSCLC) were disappointing. In the current decade, however, new insights in the interaction between tumours and the immune system have led to the development of immunotherapy as a fundamentally new concept for the treatment of NSCLC. Modern NSCLC vaccine strategies rely on better identification of antigenic targets, addition of strong immunoadjuvants, and use of more efficient delivery systems. These treatments have convincingly demonstrated to elicit potent immune responses and have shown promising efficacy signals and excellent tolerability in phase II randomised studies. This-together with recent positive phase III data in indications other than NSCLC-has helped to establish the proof of principle for cancer vaccination. In NSCLC, ongoing phase III trials are investigating this approach in different treatment settings: the Melanoma AntiGEn A3 vaccine in resected early-stage NSCLC, the L-BLP25 vaccine in locally advanced NSCLC after chemoradiotherapy, and belagenpumatucel-L, the epidermal growth factor and the TG4010 vaccine in advanced stage, either as an adjunct to chemotherapy or as maintenance after completion of chemotherapy. Mode of action, development, available clinical data, and currently ongoing phase III studies are reviewed.

Pemetrexed-induced hyperpigmentation of the skin. Anticancer Res 2011; 31:1753-1755. [PMID: 21617235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/30/2023]
Abstract
Pemetrexed (Alimta™) is used frequently for the treatment of lung cancer and is associated with various types and grades of cutaneous side-effects. We report here one patient who presented with asymptomatic hyperpigmentation of the skin, localized on the palms of the hands and the soles of the feet after administration of pemetrexed for lung cancer despite receiving standard pre-medication. This type of skin toxicity was completely reversible after withdrawal of the drug (without pharmacologic intervention) and has to our knowledge not been reported before.
