Ewing’s sarcoma is a devastating rare pediatric cancer of the bone. Intense chemotherapy temporarily controls disease in most patients at presentation but has limited effect in patients with progressive or recurrent disease. We previously described preliminary results of a novel immunotherapy, FANG(TM) (Vigil(TM)) vaccine, in which 12 advanced stage Ewing’s patients were safely treated and went on to achieve a predicted immune response (IFN? ELISPOT). We describe follow-up through year 3 of a prospective, non-randomized study comparing an expanded group of Vigil-treated advanced disease Ewing’s sarcoma patients (n=16) with a contemporaneous group of Ewing’s sarcoma patients (n=14) not treated with Vigil. Long-term follow up results show a survival benefit without evidence of significant toxicity (no = grade 3) to Vigil when administered once monthly by intradermal injection (1x10e(6) cells/injection to 1x10e(7) cells/injection). Specifically, we report a 1-year actual survival of 73% for Vigil treated patients compared to 23% in those not treated with Vigil. In addition, there was a 17.2 month difference in overall survival (OS; Kaplan-Meier) between the Vigil (median OS 731 days) and no Vigil patient groups (median OS 207 days). In conclusion, these results supply the rational for further testing of Vigil in advanced stage Ewing’s sarcoma.

To describe treatment patterns, outcomes and healthcare resource use in patients with metastatic and/or locally recurrent, unresectable gastric cancer (MGC) in Taiwan.
Patients who had received first-line therapy (platinum and/or fluoropyrimidine) followed by second-line therapy or best supportive care (BSC) only were eligible. Participating physicians provided de-identified information from patient charts. Data were summarized descriptively and Kaplan-Meier analysis was used to describe time to events.
Overall, 37 physicians contributed 122 patient charts. Of the 122 patients (median age, 61 years; 62% male), 43 (35%) received BSC only following first-line therapy, whereas 79 (65%) received second-line therapy. There was heterogeneity in second-line treatment, although fluoropyrimidine with or without a platinum agent was most frequently used. Median survival was 12.5 (interquartile range [IQR], 8.2-20.8) months from MGC diagnosis for patients receiving second-line therapy and 8.0 (IQR, 5.6-not reached) months for patients receiving BSC only. The most common treatment-related symptoms were nausea/vomiting (58%); the most common cancer-related symptoms were pain (61%), ascites (35%) and nausea/vomiting (33%). Inpatient and outpatient hospitalizations were numerically more common for patients receiving second-line therapy than for those receiving BSC only; the prevalence of hospice and skilled nursing facility stays were numerically more common for patients receiving BSC only.
In this Taiwanese MGC population, 65% received active second-line therapy with heterogeneity seen in the regimen used. Clinical outcomes suggest an unmet medical need in this population. This study may help inform clinical practice and future research to ultimately improve patient outcomes in Taiwan.

AP32788 is a tyrosine kinase inhibitor (TKI) designed to address an unmet medical need in a subset of non-small cell lung cancers (Company Pipeline, Ariad, APR 26, 2016, View Source [SID:1234511400]). Using our targeted structure-based drug discovery methods, ARIAD’s research team worked to design and build this molecule and see it from concept to nomination in under a year –a testament to the process, science, and people involved in ARIAD’s drug discovery group.

In December 2014, we nominated AP32788 for clinical development and are currently conducting studies necessary to support the filing of an investigational new drug (IND) application. We expect to file the IND by the end of 2015 and to commence a Phase 1/2 proof-of-concept clinical trial of AP32788 in 2016.

We had previously developed an algorithm for Medicare claims data to detect bone metastases associated with breast, prostate, or lung cancer. This study was conducted to examine whether this algorithm accurately documents bone metastases on the basis of diagnosis codes in Medicare claims data.
We obtained data from Medicare claims and electronic medical records of patients 65 years or older with a breast, prostate, or lung cancer diagnosis at a teaching hospital and/or affiliated clinics during 2005 or 2006. We calculated the sensitivity and positive predictive value (PPV) of our algorithm using medical records as the "gold standard." The κ statistic was used to measure agreement between claims and medical record data.
The agreement between claims and medical record data for bone metastases among breast, prostate, and lung cancer patients was 0.93, 0.90, and 0.69, respectively. The sensitivities of our algorithm for bone metastasis in patients with breast, prostate, and lung were 96.8% [95% confidence interval (CI)=83.8% to 99.4%], 91.7% (95% CI=78.2% to 97.1%), and 74.1% (95% CI=55.3% to 86.8%), respectively; and the PPVs were 90.9% (95% CI=76.4% to 96.9%), 91.7% (95% CI=78.2% to 97.1%), and 71.4% (95% CI=52.9% to 84.8%), respectively.
The algorithm for detecting bone metastases in claims data had high sensitivity and PPV for breast and prostate cancer patients. Sensitivity and PPV were lower but still moderate for lung cancer patients.

To prospectively test the diagnostic accuracy of the percentage of prostate specific antigen (PSA) isoform [-2]proPSA (%p2PSA) and the Prostate Health Index (PHI), and to determine their role for discrimination between significant and insignificant prostate cancer at initial and repeat prostate biopsy in men aged ≤65 years.
The diagnostic performance of %p2PSA and PHI were evaluated in a multicentre study. In all, 769 men aged ≤65 years scheduled for initial or repeat prostate biopsy were recruited in four sites based on a total PSA (t-PSA) level of 1.6-8.0 ng/mL World Health Organization (WHO) calibrated (2-10 ng/mL Hybritech-calibrated). Serum samples were measured for the concentration of t-PSA, free PSA (f-PSA) and p2PSA with Beckman Coulter immunoassays on Access-2 or DxI800 instruments. PHI was calculated as (p2PSA/f-PSA × √t-PSA). Uni- and multivariable logistic regression models and an artificial neural network (ANN) were complemented by decision curve analysis (DCA).
In univariate analysis %p2PSA and PHI were the best predictors of prostate cancer detection in all patients (area under the curve [AUC] 0.72 and 0.73, respectively), at initial (AUC 0.67 and 0.69) and repeat biopsy (AUC 0.74 and 0.74). t-PSA and %f-PSA performed less accurately for all patients (AUC 0.54 and 0.62). For detection of significant prostate cancer (based on Prostate Cancer Research International Active Surveillance [PRIAS] criteria) the %p2PSA and PHI equally demonstrated best performance (AUC 0.70 and 0.73) compared with t-PSA and %f-PSA (AUC 0.54 and 0.59). In multivariate analysis PHI we added to a base model of age, prostate volume, digital rectal examination, t-PSA and %f-PSA. PHI was strongest in predicting prostate cancer in all patients, at initial and repeat biopsy and for significant prostate cancer (AUC 0.73, 0.68, 0.78 and 0.72, respectively). In DCA for all patients the ANN showed the broadest threshold probability and best net benefit. PHI as single parameter and the base model + PHI were equivalent with threshold probability and net benefit nearing those of the ANN. For significant cancers the ANN was the strongest parameter in DCA.
The present multicentre study showed that %p2PSA and PHI have a superior diagnostic performance for detecting prostate cancer in the PSA range of 1.6-8.0 ng/mL compared with t-PSA and %f-PSA at initial and repeat biopsy and for predicting significant prostate cancer in men aged ≤65 years. They are equally superior for counselling patients before biopsy.
