    Abstract: 9537 Background: Patients with cancer have an increased risk of venous thromboembolism (VTE). However, routine VTE prophylaxis is generally not recommended in ambulatory cancer patients. Several randomized controlled trials (RCTs) of low-molecular-weight heparin (LMWH) in ambulatory cancer patients have been reported with inconclusive results. Methods: A systematic review of RCTs of LMWH in ambulatory cancer patients without a VTE diagnosis was conducted. Included trials had to report VTE as primary or secondary outcome. An extensive electronic database search was conducted, including Medline, EMBASE, Cochrane Library along with abstracts from major meetings. Dual-blinded data extraction was performed. Meta-analysis was conducted using Mantel and Haenszel method to estimate relative risk (RR) and absolute risk difference (ARD) ± 95% CI. Primary outcomes in this analysis were all reported VTE and major bleeds. Most trials did not require VTE screening by imaging, precluding a separate analysis of asymptomatic VTE events. Results: Six RCTs were identified with a total of 2,648 patients including 1,525 receiving LMWH and 1,123 controls. No significant heterogeneity was observed across trials. Among patients receiving LMWH, the crude incidence of VTE was 2.95% compared to 5.25% among control patients. LMWH reduced the RR of VTE by 36% compared to controls (RR=0.64 [0.44 - 0.94] , P=0.021), and reduced the ARD by 1.8% [0.2% - 3.4%]. Major bleeding events were reported in 1.57% LMWH patients compared to 0.98% in controls. The non-significant RR increase by LMWH for major bleeding was 1.85 [0.923 - 3.68] , P=0.081, with an ARD of 0.9% [0.0% - 1.8%]. Results were comparable in the analysis limited to studies with VTE as primary outcome. Conclusions: While patients experienced a 36% relative risk reduction in VTE with LMWH, the absolute risk reduction was small, and concerns remain about the potential increase in major bleeding. Therefore, routine VTE prophylaxis in ambulatory cancer patients cannot be recommended at this time. Additional research is needed to identify cancer outpatients at high risk for VTE, in whom prophylaxis may have a more favorable risk-benefit ratio. [Table: see text]

    Abstract: 3625 Background: Recent publications have drawn attention to the escalating costs of drugs utilized for the treatment and supportive care of colorectal cancer (CRC) patients. As more advanced chemotherapeutic and supportive agents are approved, the cost of treatment will likely continue to increase. The goal of this analysis was to estimate costs of frequently used CRC chemotherapeutics and other commonly prescribed agents. Methods: Costs of drugs in CRC regimens for patients participating in a prospective, observational study from 115 community oncology practices between March 2002 and March 2005 were calculated. Standard dosages and schedules were determined through literature review and an expert CRC oncologist. Trimmed mean (90%) costs were computed using average wholesale prices (AWP) retrieved from the Lexicon Database Drug Product (January 2005). All prices noted are 95% AWP. All chemotherapeutic drugs were combined to arrive at regimen specific prices. Other regimens were defined as regimens with less than four patients. Price per cycle was estimated based on a standard patient BSA of 2.0 m 2 and standard regimen schedules. Growth factor costs were derived from expected per cycle utilization, while prices for other supportive drugs were calculated using dosages for single events. Results: Patients were categorized into the following regimens ( table below). The price of a commonly used monoclonal antibody is: Bevacizumab ($2613), based on every 2 week dosing. Growth factor prices (per cycle) were estimated: Filgrastim ($2499), Pegfilgrastim ($2928), Epoetin ($552), and Darbepoetin Alfa ($1002). Prices per event for other commonly used agents were: Atropine ($245), Loperamide ($3), Ondansetron ($931), and Granisetron ($232). Conclusions: Prices of CRC regimens vary considerably, with newer agents and supportive drugs adding substantially to costs, particularly in late stage disease. Research on improved outcomes or treatment benefits associated with high cost treatment is warranted. [Table: see text] [Table: see text]

    Abstract: 9009 Background: Venous thromboembolism (VTE) contributes to morbidity and mortality in cancer patients and is a frequent complication of anti-cancer therapy. We examined the frequency, risk factors and trends associated with VTE among hospitalized US cancer patients. Methods: We conducted a retrospective cohort study using the discharge database of the University Health System Consortium. This included all 1,824,316 hospitalizations of cancer patients between 1995 and 2003 at 133 United States medical centers. To avoid overestimation, only a single randomly chosen hospitalization was included for patients with multiple admissions. Results: Among 1,015,598 individual cancer patients, 34,357 (3.4%) were diagnosed with deep venous thrombosis and 11,515 with pulmonary embolism (PE) (1.1%) for an overall VTE rate of 4.1%. Subgroups of cancer patients with highest rates included Black ethnicity (5.1% per hospitalization) and those on chemotherapy (4.9%). Sites of cancer with the highest rates of VTE included pancreas (8.2%), kidney (5.7%), ovary (5.6%), lung (5.1%) and stomach (4.9%). Amongst hematologic malignancies, myeloma (5%), non-Hodgkin’s lymphoma (4.8%) and Hodgkin’s disease (4.6%) had the highest rates of VTE. The rate of VTE rose from 3.6% per hospitalization in 1995–96 to 4.6% in 2002–03, an increase of 28%, including a near-doubling of PE rates from 0.8% to 1.5% (P 〈 0.0001). Among patients receiving chemotherapy, rates of VTE rose from 3.9% per hospitalization to 5.7%, an increase of 47% (P 〈 0.0001). In contrast, patients undergoing surgery for breast, head and neck, pancreatic or spinal cancers, experienced no significant change in the rate of VTE. Use of diagnostic procedures for VTE also did not increase over the study period. Conclusions: The rate of VTE, including PE, among hospitalized cancer patients has increased significantly in recent years. Black patients, those on chemotherapy and those with certain types of cancer are disproportionately at increased risk. The rise in VTE does not appear to be attributable to an increased utilization of diagnostic procedures. Further efforts to increase thromboprophylaxis compliance during hospitalization are needed. No significant financial relationships to disclose.

    Abstract: Dickkopf-1 (DKK1) modulates Wnt signaling, promoting tumor growth, metastasis, and immunosuppression. High DKK1 expression has been detected in various tumor types—including biliary tract cancer (BTC)—and is associated with poor prognosis. DKN-01—a humanized mAb targeting DKK1—was evaluated in a phase I multicenter study in combination with gemcitabine and cisplatin in patients with unresectable or metastatic BTC with no prior systemic therapy for advanced disease. Patients and Methods: This study included a dose-escalation phase assessing DKN-01 at two dose levels (150 mg and 300 mg) combined with gemcitabine (1,000 mg/m2) and cisplatin (25 mg/m2) followed by dose expansion. Primary endpoints evaluated safety and tolerability; secondary endpoints evaluated efficacy, pharmacokinetics, and circulating biomarkers. Results: Fifty-one patients with intrahepatic cholangiocarcinoma (63%), extrahepatic cholangiocarcinoma (8%), and gallbladder cancer (29%) were enrolled. No dose-limiting toxicities were seen, and the expansion phase proceeded with DKN-01 300 mg (N = 47). The most frequent grade 3/4 treatment-emergent adverse events included neutropenia (60%), thrombocytopenia (34%), and anemia (23%). The objective response rate was 21.3% and median progression-free survival was 8.7 months (95% confidence interval, 5.4–10.3 months). Better outcomes were associated with biomarkers of angiogenesis inhibition (increased sVEGFR1 and lower VEGF-C) and reduced inflammation (lower IL6 and decreased TNFα). Conclusions: DKN-01 300 mg was well tolerated in this combination but did not appear to have additional activity beyond historically reported efficacy with gemcitabine/cisplatin alone. Exploratory pharmacokinetic and biomarker data indicate potential antiangiogenic and immunomodulatory activity of DKN-01/chemotherapy and the need for increased dose/intensity. A study with DKN-01 600 mg in combination with a PD-1 inhibitor in BTC is ongoing.

    Abstract: Since the beginning of its guidelines program in 1993, ASCO has continually sought ways to produce a greater number of guidelines while maintaining its commitment to using the rigorous development methods that minimize the biases that threaten the validity of practice recommendations. ASCO is implementing a range of guideline development and implementation innovations. In this article, we describe innovations that are designed to (1) integrate consideration of multiple chronic conditions into practice guidelines; (2) keep more of its guidelines current by applying evolving signals or (more) rapid, for-cause updating approaches; (3) increase the number of high-quality guidelines available to its membership through endorsement and adaptation of other groups’ products; (4) improve coverage of its members’ guideline needs through a new topic nomination process; and (5) enhance dissemination and promote implementation of ASCO guidelines in the oncology practice community through a network of volunteer ambassadors. We close with a summary of ASCO’s plans to facilitate the integration of data from its rapid learning system, CancerLinQ, into ASCO guidelines and to develop tactics through which guideline recommendations can be embedded in clinicians’ workflow in digital form. We highlight the challenges inherent in reconciling the need to provide clinicians with more interactive, point-of-care guidance with ASCO’s abiding commitment to methodologic rigor in guideline development.
