    Abstract Fibroblast growth factors (FGFs) and their receptors (FGFRs) are transmembrane growth factor receptors with wide tissue distribution. FGF/FGFR signaling is involved in neoplastic behavior and also development, differentiation, growth, and survival. FGFR germline mutations (activating) can cause skeletal disorders, primarily dwarfism (generally mutations in FGFR3), and craniofacial malformation syndromes (usually mutations in FGFR1 and FGFR2); intriguingly, some of these activating FGFR mutations are also seen in human cancers. FGF/FGFR aberrations reported in cancers are mainly thought to be gain-of-function changes, and several cancers have high frequencies of FGFR alterations, including breast, bladder, or squamous cell carcinomas (lung and head and neck). FGF ligand aberrations (predominantly gene amplifications) are also frequently seen in cancers, in contrast to hereditary syndromes. There are several pharmacologic agents that have been or are being developed for inhibition of FGFR/FGF signaling. These include both highly selective inhibitors as well as multi-kinase inhibitors. Of note, only four agents (ponatinib, pazopanib, regorafenib, and recently lenvatinib) are FDA-approved for use in cancer, although the approval was not based on their activity against FGFR. Perturbations in the FGFR/FGF signaling are present in both inherited and malignant diseases. The development of potent inhibitors targeting FGF/FGFR may provide new tools against disorders caused by FGF/FGFR alterations.

    Abstract Background: We analyzed clinical associations of MET alterations in the plasma of patients with diverse malignancies.
    Methods: Digital sequencing of circulating tumor DNA (ctDNA) (54-70 genes) was performed in 438 patients; 263 patients also had tissue sequencing (182-315 genes). The most represented tumor types were gastrointestinal (28.1%), brain (24.9%), and lung (23.2%). Most patients (71.2%) had recurrent/metastatic disease.
    Results: MET alterations were observed in 31 patients (7.1%) and correlated with bone metastasis (P = 0.007), with TP53 (P = 0.001) and PTEN (P = 0.003) abnormalities, and with an increased number of alterations (median, 4 vs 1, P = 0.001) (all multivariable analyses). Patients with MET alterations demonstrated a significantly shorter median time to metastasis/recurrence (1.0 vs 10.4 months, P = 0.044, multivariable) and a poorer survival (30.6 vs 58.4 months, P = 0.013, univariate only). Of the 31 patients with MET alterations, 18 also had tissue testing; only two also had tissue MET alterations (11.1%); MET alterations were detected at a lower frequency in tissue (1.14%) compared to ctDNA (7.1%), with P = 0.0002.
    Conclusions: In conclusion, the detection of MET alterations by liquid biopsy is feasible. MET ctDNA alterations were associated with a poorer prognosis, higher numbers of genomic abnormalities, and bone metastases. The correlation with bone metastases may explain the higher frequency of MET alterations in blood ctDNA than in tissue (since bones are rarely biopsied) and the previous observations of bone-predominant responses to MET inhibitors. The high number of co-altered genes suggests that MET inhibitors may need to be combined with other agents to induce/optimize responses.

    Abstract Purpose: Genomic alterations in blood-derived circulating tumor DNA (ctDNA) from patients with colorectal cancers were correlated with clinical outcomes.
    Patients and methods: Next-generation sequencing of ctDNA (54- to 73-gene panel) was performed in 94 patients with colorectal cancer.
    Results: Most patients (96%) had metastatic or recurrent disease at the time of blood draw. The median number of nonsynonymous alterations per patient was three (range, zero to 30). The most frequently aberrant genes were
    Conclusion: Patients with colorectal cancer have heterogeneous ctDNA profiles, and most harbor potentially actionable ctDNA alterations. Matched therapy yielded higher rates of stable disease for 6 months or more, partial response, or complete response. ctDNA assessment may have clinical utility and merits further investigation.

    Abstract The effects of incorporating a biomarker-based (personalized or precision) selection strategy on drug development timelines for new oncology drugs merit investigation. Here we accessed documents from the Food and Drug Administration (FDA) database for anticancer agents approved between 09/1998 and 07/2014 to compare drugs developed with and without a personalized strategy. Sixty-three drugs were included (28 [44%] personalized and 35 [56%] non-personalized). No differences in access to FDA-expedited programs were observed between personalized and non-personalized drugs. A personalized approach for drug development was associated with faster clinical development (Investigational New Drug [IND] to New Drug Application [NDA] submission; median = 58.8 months [95% CI 53.8-81.8] vs. 93.5 months [95% CI 73.9-112.9], P =.001), but a similar approval time (NDA submission to approval; median=6.0 months [95% CI 5.5-8.4] vs. 6.1 months [95% CI 5.9-8.3], P = .756) compared to a non-personalized strategy. In the multivariate model, class of drug stratified by personalized status (targeted personalized vs. targeted non-personalized vs. cytotoxic) was the only independent factor associated with faster total time of clinical drug development (clinical plus approval phase, median = 64.6 vs 87.1 vs. 112.7 months [cytotoxic], P = .038). Response rates (RR) in early trials were positively correlated with RR in registration trials (r = 0.63, P = <.001), and inversely associated with total time of drug development (r = -0.29, P = .049). In conclusion, targeted agents were developed faster than cytotoxic agents. Shorter times to approval were associated, in multivariate analysis, with a biomarker-based clinical development strategy.

    Abstract Background: Topoisomerase I (TOPO1) and topoisomerase IIα (TOP2A) are specific targets of multiple chemotherapy drugs. Increased expression of TOPO1 protein and amplification of the TOP2A gene have been associated with treatment response in colorectal and breast cancers, respectively. TOPO1 and TOP2A may be potential therapeutic targets in other malignancies as well.
    Summary of methods: We analysed TOPO1 protein expression and TOP2A gene amplification in patients (n = 24,262 specimens) with diverse cancers. Since HER2 and TOP2A co-amplification have been investigated for predictive value regarding anthracycline benefit, we analysed specimens for HER2 amplification as well.
    Results: Overexpressed TOPO1 protein was present in 51% of the tumours. Four percent of the tumours had TOP2A amplification, with gallbladder tumours and gastroesophageal/oesophageal tumours having rates over 10%. Overall, 4903 specimens were assessed for both TOP2A and HER2 amplification; 129 (2.6%) had co-amplification. High rates (>40%) of HER2 amplification were seen in patients with TOP2A amplification in breast, ovarian, gastroesophageal/oesophageal and pancreatic cancer.
    Conclusion: Our data indicate that increased TOPO1 expression and TOP2A amplification, as well as HER2 co-alterations, are present in multiple malignancies. The implications of these observations regarding sensitivity to chemotherapy not traditionally administered to these tumour types merits investigation.

    Abstract Bevacizumab is one of the most widely used antiangiogenic drugs in oncology, but the overall beneficial effects of this VEGF-A targeting agent are relatively modest, in part due to the lack of a biomarker to select patients most likely to respond favorably. Several molecular aberrations in cancer influence angiogenesis, including mutations in the tumor suppressor gene TP53, which occur frequently in many human malignancies. In this study, we present a multiple regression analysis of transcriptomic data in 123 patients with non-small cell lung cancer (NSCLC) showing that TP53 mutations are associated with higher VEGF-A expression (P = 0.006). This association was interesting given a recent retrospective study showing longer progression-free survival in patients with diverse tumors who receive bevacizumab, if tumors harbor mutant TP53 instead of wild-type TP53. Thus, our current findings linking TP53 mutation with VEGF-A upregulation offered a mechanistic explanation for why patients exhibit improved outcomes after bevacizumab treatment when their tumors harbor mutant TP53 versus wild-type TP53. Overall, this work warrants further evaluation of TP53 as a ready biomarker to predict bevacizumab response in NSCLC and possibly other tumor types.

    Abstract Purpose: Multiplex genomic tests are enabling oncologists to interrogate the DNA of their patients. However, few oncologists are proficient with respect to the implications of complex molecular diagnostics. We initiated a Molecular Tumor Board that focused on individual patients with advanced cancer whose tumors underwent genomic profiling, and here report our experience with breast cancer.
    Methods: A multidisciplinary team that included physicians, scientists, geneticists, and bioinformatics/pathway specialists attended. All molecular tests were performed in a Clinical Laboratory Improvement Amendments environment (next-generation sequencing, 182 or 236 genes).
    Results: Forty of 43 patients (93%; mean age, 59 years) had at least one theoretically actionable aberration (mean, 4.79 anomalies/patient). Median time from ordering to report was 27 days (median of approximately 11 days for specimen acquisition and approximately 14 days for diagnostic processing). Even if we considered distinct abnormalities in a gene as the same, there were only two patients with an identical molecular profile. Seventy-three genes (206 abnormalities; 119 distinct) were aberrant. Seventeen of the 43 patients (40%; median, seven previous therapies in the metastatic setting) were treated in a manner consistent with Molecular Tumor Board discussions; seven (16% of 43, or 41% of 17) achieved stable disease for 6 or more months (n = 2) or partial remission (n = 5). Lack of access to targeted medication was the most common reason that patients could not be treated.
    Conclusion: Multidisciplinary molecular tumor boards may help to optimize the management of patients with advanced, heavily pretreated breast cancer who have undergone genomic testing. Facilitating availability of appropriately targeted drugs and clinical trials is needed.

    Abstract Cyclin genes are key regulatory components of the cell cycle. With the development of new agents, cyclin-related genes are becoming increasingly important as they can be targeted. Yet, the biological implications of these alterations have not been fully studied. Clinical characteristics and outcome parameters were compared for patients harboring cyclin alterations versus not. CCN alterations were found in 13% of our population (50/392; all amplifications) and were associated with breast cancer (P < 0.0001), a higher median number of concomitant molecular alterations (P < 0.0001), and liver metastases (P = 0.046). Harboring a cyclin amplification was not associated with overall survival, the time to metastasis/recurrence, nor with the best progression-free survival. In a Cox regression model, gastrointestinal histology (P < 0.0001), PTEN (P < 0.0001), and CDK alterations (P = 0.041) had a significant association with poorer overall survival. CCN amplifications significantly correlated with alterations in FGF/FGFR family genes as well as in MET and ARFRP1. An extended correlation study shed light on a network of co-amplifications influenced in part by genes that were localized on the same amplicons. CCN amplifications are common across cancers and had distinctive biological associations. Customized combinations targeting the cyclin pathway as well as the extended co- amplification network may be necessary in order to address resistance mechanisms.
