    Abstract Background: Comprehensive geriatric assessment (CGA) is recommended by international guidelines prior to initiation of systemic anti-cancer treatment (SACT). In practice, CGA is limited by time constraints, lack of resources and expert interpretation.
    Aims: The primary objective of this pilot study was to establish the prevalence of frailty (assessed by G8), cognitive impairment (assessed by Mini-Cog), and risk of chemotherapy toxicity (assessed by CARG Chemo-Toxicity Calculator) among patients (pts) ≥65 years commencing SACT. We selected these three screening tools due to the ease of conducting them in a busy outpatient setting. In addition, they have been validated to predict frailty and risk of toxicity from SACT among older adults with cancer.
    Methods: Eligible participants were identified from medical oncology clinics. Assessments were conducted in an outpatient setting by treating physicians. Pt records were reviewed to gather demographic and cancer details. Statistical analyses were conducted using SPSS statistical software.
    Results: Sixty-three participants were enrolled. The mean age of participants was 73yrs (range=65-88). Thirty-three (52.4%) were female and 30 (47.6%) were male. The majority (n=38, 60.3%) had metastatic cancer. The mean G8 score was 11.9 (range=6-19). Eighty-three percent had a G8 score ≤14. Mini-Cog was positive in 13 pts (21%). The mean CARG score was 7.5 (range=0-16), and 80% had a risk of at least 50% grade ≥3 toxicity. Of these, 48 (76.2%) received chemotherapy and 15 (23.8%) received non-cytotoxic SACT. In multi-variate analyses, age, cancer type, treatment type, and disease stage did not impact G8, Mini-Cog, or CARG scores.
    Conclusions: Our study has several limitations but suggests that the majority of older adults with cancer would qualify for formal CGA assessment. The risk of high-grade toxicity from SACT is substantial in this cohort. Chronological age was not found to negatively impact pts' frailty, cognition, or risk of toxicity.

    Abstract PTPN11 encodes the SHP2 protein tyrosine phosphatase that activates the mitogen-activated protein kinase (MAPK) pathway upstream of KRAS and MEK. PTPN11 /Shp2 somatic mutations occur frequently in Juvenile myelomonocytic leukaemia (JMML); however, the role of mutated PTPN11 in lung cancer tumourigenesis and its utility as a therapeutic target has not been fully addressed. We applied mass-spectrometry-based genotyping to DNA extracted from the tumour and matched the normal tissue of 356 NSCLC patients (98 adenocarcinomas (LUAD) and 258 squamous cell carcinomas (LUSC)). Further, PTPN11 mutation cases were identified in additional cohorts, including TCGA, Broad, and MD Anderson datasets and the COSMIC database. PTPN11 constructs harbouring PTPN11 E76A, A72D and C459S mutations were stably expressed in IL-3 dependent BaF3 cells and NSCLC cell lines (NCI-H1703, NCI-H157, NCI-H1299). The MAPK and PI3K pathway activation was evaluated using Western blotting. PTPN11 /Shp2 phosphatase activity was measured in whole-cell protein lysates using an Shp2 assay kit. The Shp2 inhibitor (SHPi) was assessed both in vitro and in vivo in a PTPN11 -mutated cell line for improved responses to MAPK and PI3K targeting therapies. Somatic PTPN11 hotspot mutations occurred in 4/98 (4.1%) adenocarcinomas and 7/258 (2.7%) squamous cells of 356 NSCLC patients. Additional 26 PTPN11 hotspot mutations occurred in 23 and 3 adenocarcinomas and squamous cell carcinoma, respectively, across the additional cohorts. Mutant PTPN11 significantly increased the IL-3 independent survival of Ba/F3 cells compared to wildtype PTPN11 ( p < 0.0001). Ba/F3, NCI-H1703, and NCI-H157 cells expressing mutant PTPN11 exhibited increased PTPN11 /Shp2 phosphatase activity and phospho-ERK1/2 levels compared to cells expressing wildtype PTPN11 . The transduction of the PTPN11 inactivating mutation C459S into NSCLC cell lines led to decreased phospho-ERK, as well as decreased phospho-AKT in the PTPN11 -mutated NCI-H661 cell line. NCI-H661 cells ( PTPN11 -mutated, KRAS ...

    Abstract Vascular endothelial growth factor (VEGF) is a rational target for advanced non-small cell lung cancer (NSCLC), a hypothesis validated by the recent Eastern Cooperative Oncology Group E4599 trial showing that the addition of the VEGF monoclonal antibody bevacizumab to chemotherapy prolongs overall survival. Several new tyrosine kinase inhibitors targeting the VEGF pathway are currently in advanced clinical development for NSCLC and offer several possible advantages compared with monoclonal antibodies, including oral administration, more flexible dosing, a broader spectrum of target inhibition, and different toxicity profiles. Among these agents, vandetanib (ZD6474), an inhibitor of the VEGF receptor (VEGFR)-2 and epidermal growth factor receptor tyrosine kinase, has been the most extensively studied. In a randomized phase II study of patients with platinum-refractory NSCLC, including squamous histology, vandetanib prolonged progression-free survival compared with gefitinib. In another phase II trial, an improvement in progression-free survival was observed for vandetanib in combination with docetaxel compared with docetaxel alone. AZD2171 is an inhibitor of VEGFR-1, VEGFR-2, and VEGFR-3 and other tyrosine kinases that has shown clinical activity in NSCLC in combination with carboplatin and paclitaxel. Several phase III trials are under way testing these agents either as monotherapy or in combination with chemotherapy in patients with lung cancer. Early results with these agents, and others being tested, raise the possibility that there will eventually be multiple VEGF-targeted therapies available in the clinic that can potentially benefit a broader range of patients with advanced-stage NSCLC.

    Abstract Neoadjuvant chemotherapy (NAC) is long established as part of the multi-modality management of locally advanced breast cancer or inflammatory breast cancer, leading to significantly improved outcome. Numerous recent studies have compared the use of anthracycline-based NAC with adjuvant chemotherapy in earlier-stage disease, and have shown equivalent disease-free and overall survival rates with increased breast conservation rates. These studies have also shown that a pathological complete response after NAC is associated with improved long-term outcome. More recently, the taxanes have been introduced into clinical trials of NAC with increased overall and pCR rates. However, there is no evidence that the addition of taxanes to neoadjuvant anthracycline-based chemotherapy significantly improves long-term disease free survival or overall survival. This paper reviews these trials, as well as trials of dose-dense and trastuzumab-containing NAC regimens. The review discusses the potential for NAC to replace prolonged adjuvant trials in the assessment of new therapeutic agents (using pathological complete response as a surrogate for long-term outcome), to be used as an in vivo chemosensitivity assay to guide further treatment, and to identify molecular markers that correlate with tumour sensitivity or resistance to chemotherapeutic agents so that the treatment of patients can be individualised.

    Abstract Non-Hodgkin lymphoma (NHL) causes many deaths worldwide, and its incidence is increasing. Although some cases are associated with immunodeficiency, autoimmunity, or viral infections, in most cases the causes of NHL are not understood. However, there have been some important advances in our understanding of the development of healthy lymphocytes and the pathogenesis of NHL over the past 10 years. These advances have been accompanied by an improvement in treatment for NHL. Before the late 1990s, the only treatment option available was cytotoxic chemotherapy. In the past 10 years, however, high-dose chemotherapy and autologous stem-cell reconstitution have become established parts of treatment for aggressive lymphoma. Furthermore, monoclonal antibodies have become another therapeutic option. Rituximab (an anti-CD20 monoclonal antibody) is the most advanced monoclonal antibody in clinical trials and has become part of standard treatment for some lymphomas. Rituximab, and many other monoclonal antibodies, continue to be assessed in clinical studies. Monoclonal antibodies can be used alone or in combination with standard-dose or high-dose chemotherapy, and they can also be conjugated to radionuclides to enhance cytotoxicity. Here, we review advances in the treatment of NHL that have occurred over the past 10 years.

    Abstract The EGFR T790M somatic mutation is the most common mechanism of resistance to tyrosine kinase inhibitors in NSCLC. Patients with advanced disease are not always amenable to repeat biopsy for further molecular analysis. Developing noninvasive methods to detect T790M in cell-free DNA in the absence of tissue is being actively investigated. Unfortunately, the low sensitivity of plasma for detection of T790M has limited its clinical use. Exhaled breath condensate (EBC) is an easily collected sample that is known to harbor cell-free DNA, including lung cancer mutations. This report details the potential utility of exhaled breath condensate in the detection of the EGFR T790M mutation.

    Abstract Purpose: Mammographic screening has led to an increase in the number of small, node-negative breast cancers being diagnosed. Node-negative breast cancers that are < or = 1 cm are stage T1a,bN0M0. Controversy surrounds the prognosis of these patients with locoregional therapy only and the need for adjuvant systemic therapy.
    Methods: We performed a comprehensive review of the literature describing outcome and prognostic factors in stage T1a,bN0M0 breast cancer. We also reviewed current guidelines for systemic therapy in these patients.
    Results: Early studies reported 10-year relapse-free survival (RFS) rates higher than 90% without adjuvant systemic therapy, but some more recent data suggest inferior outcomes. High tumor grade is the most consistent factor associated with poor prognosis. Other adverse prognostic factors are younger age, lymphovascular invasion (LVI), high Ki-67, and larger tumors within the T1a,b subgroup. Patients with high-grade tumors and/or LVI may have 10-year RFS rates of less than 75% in the absence of systemic therapy. The prognostic significance of hormone receptor status is unclear. Current guidelines for the systemic management of early-stage breast cancer differ when applied to stage T1a,bN0M0, reflecting the controversial nature of the issue.
    Conclusion: Adjuvant systemic therapy is advisable for most patients with stage T1a,bN0M0 breast cancer who have grade 3 tumors and/or LVI. Other T1a,bN0M0 cases should be considered for systemic therapy based on clinicopathologic factors with known prognostic significance and assessment of the risk-benefit ratio. More reliable tools are needed to assess the prognosis of patients with stage T1a,bN0M0 breast cancer and their potential to benefit from specific therapeutic agents.
