BackgroundA Memorial Sloan Kettering (MSKCC) nomogram predicts disease specific survival (DSS) for gastric adenocarcinoma. The goal of this study is to use a cancer registry to compare nomogram predicted survival with actual survival in the general population.MethodsAll patients undergoing surgery for gastric adenocarcinoma from the Surveillance, Epidemiology, and End Results (SEER) database (1988–2012) were studied.Results6954 patients were identified. Majority of cancers were in the antrum (30.2%), and had intestinal histology (73.7%). Median follow‐up was 8.2 years. Five year DSS for nomogram risk groups (0–25%, 26–50%, 51–75%, and 76–100%) was 23%, 48%, 57%, and 81% respectively. Actual DSS was 7–15% lower than nomogram predicted DSS. Relative to patients in the 76–100% 5‐year DSS risk group, patients in the 0–25%, 26–50%, and 51–75% groups had significantly higher risks of death with hazard ratios of 6.84 (95%CI 6.12–7.65), 3.30 (95%CI 2.83–3.86), and 2.64 (95%CI 2.30–3.03), respectively (all P < 0.001). The concordance index for 5‐year nomogram predicted DSS was 0.68 (95%CI 0.67–0.69).ConclusionsThe MSKCC gastric cancer nomogram over‐estimates DSS from gastric cancer in the general population and has a moderate concordance index. Predictive tools generated at specialized institutions may not perform as well in the general population. J. Surg. Oncol. 2015; 112:377–380. © 2015 Wiley Periodicals, Inc.

The myeloproliferative neoplasms (MPN) including polycythaemia vera (PV), essential thrombocythaemia and primary myelofibrosis (PMF) are rare diseases contributing to significant morbidity. Symptom management is a prime treatment objective but current symptom assessment tools have not been validated compared to the general population. The MPN‐symptom assessment form (MPN‐SAF), a reliable and validated clinical tool to assess MPN symptom burden, was administered to MPN patients (n = 106) and, for the first time, population controls (n = 124) as part of a UK case–control study. Mean symptom scores were compared between patients and controls adjusting for potential confounders. Mean patient scores were compared to data collected by the Mayo Clinic, USA on 1,446 international MPN patients to determine patient group representativeness. MPN patients had significantly higher mean scores than controls for 25 of the 26 symptoms measured (P < 0.05); fatigue was the most common symptom (92.4% and 78.1%, respectively). Female MPN patients suffered worse symptom burden than male patients (P < 0.001) and substantially worse burden than female controls (P < 0.001). Compared to the Mayo clinic patients, MPN‐UK patients reported similar symptom burden but lower satiety (P = 0.046). Patients with PMF reported the worst symptom burden (88.3%); significantly higher than PV patients (P < 0.001). For the first time we report quality of life was worse in MPN‐UK patients compared with controls (P < 0.001). Am. J. Hematol. 90:864–870, 2015. © 2015 Wiley Periodicals, Inc.

SummarySixty‐four transplant‐eligible patients with newly diagnosed multiple myeloma (NDMM) received carfilzomib (days 1, 2, 8, 9, 15, 16), 300 mg/m2 cyclophosphamide (days 1, 8, 15), 100 mg thalidomide (days 1–28) and 40 mg dexamethasone (days 1, 8, 15, 22) in 28‐day cycles (CYKLONE regimen). Carfilzomib was dose‐escalated to 15/20, 20/27, 20/36 and 20/45 mg/m2 to determine the maximum tolerated dose (MTD), which was 20/36 mg/m2. Regardless of attribution, common Grade 3 or higher adverse events were lymphopenia (38%), neutropenia (23%) and anaemia (20%). All peripheral neuropathy (31%) was Grade 1 and considered most likely to be thalidomide‐related. Common cardiac or pulmonary events of any grade in ≥5% of patients included dyspnoea (20%) and cough (6%). Overall (N = 64), 91% of patients achieved a best response of partial response or better across all cycles of treatment, including five patients with complete responses. At the MTD (n = 29), 59% of patients achieved a very good partial response or better after four cycles (primary end point). Stem cell collection was successful in all patients in whom it was attempted (n = 42). Progression‐free survival and overall survival at 24 months was 76% and 96%, respectively (median follow‐up of 17·5 months). CYKLONE appears highly efficacious in NDMM patients, with manageable toxicities.

AbstractTo evaluate the impact of a patient‐centered symposium as an educational intervention on a broad population of cancer patients. We developed a comprehensive patient symposium. Through voluntary questionnaires, we studied the impact of this cancer symposium on quality of life, cancer‐specific knowledge, and symptom management among cancer patients. Symposium attendees were provided surveys prior to and 3 months following the educational intervention. Surveys included (1) EORTC‐QLQ‐C30; (2) disease understanding tool developed for this conference; (3) validated disease‐specific questionnaires. Changes over time were assessed using McNemar's tests and paired t‐tests for categorical and continuous variables, respectively. A total of 158 attendees completed the pre‐convention survey. Most respondents reported at least “quite a bit” of understanding regarding treatment options, screening modalities, symptomatology, and cancer‐related side effects. Attendees endorsed the least understanding of disease‐related stress, risk factors, fatigue management, and legal issues related to disease/treatment. At 3 months, there was improvement in understanding (12 of 14 areas of self‐reported knowledge especially regarding nutrition, and stress/fatigue management). However, no significant change was seen in QLQ‐C30 functioning, fatigue, pain, or insomnia. A patient symposium, as an educational intervention improves a solid knowledge base amongst attendees regarding their disease, increases knowledge in symptom management, but may be insufficient to impact QoL as a single intervention.

Purpose To develop a genomic signature that predicts benefit from trastuzumab in human epidermal growth factor receptor 2–positive breast cancer. Patients and Methods DASL technology was used to quantify mRNA in samples from 1,282 patients enrolled onto the Combination Chemotherapy With or Without Trastuzumab in Treating Women With Breast Cancer (North Central Cancer Treatment Group N9831 [NCCTG-N9831]) adjuvant trastuzumab trial. Cox proportional hazard ratios (HRs), adjusted for significant clinicopathologic risk factors, were used to determine the association of each gene with relapse-free survival (RFS) for 433 patients who received chemotherapy alone (arm A) and 849 patients who received chemotherapy plus trastuzumab (arms B and C). Network and pathway analyses were used to identify key biologic processes linked to RFS. The signature was built by using a voting scheme. Results Network and functional ontology analyses suggested that increased RFS was linked to a subset of immune function genes. A voting scheme model was used to define immune gene enrichment based on the expression of any nine or more of 14 immune function genes at or above the 0.40 quantile for the population. This model was used to identify immune gene–enriched tumors in arm A and arms B and C. Immune gene enrichment was linked to increased RFS in arms B and C (HR, 0.35; 95% CI, 0.22 to 0.55; P < .001), whereas arm B and C patients who did not exhibit immune gene enrichment did not benefit from trastuzumab (HR, 0.89; 95% CI, 0.62 to 1.28; P = .53). Enriched immune function gene expression as defined by our predictive signature was not associated with increased RFS in arm A (HR, 0.90; 95% CI, 0.60 to 1.37; P = .64). Conclusion Increased expression of a subset of immune function genes may provide a means of predicting benefit from adjuvant trastuzumab.
