Combined CT venography and pulmonary angiography can accurately depict the femoropopliteal deep veins, permitting concurrent testing for venous thrombosis and pulmonary embolism. CT venography also defines pelvic or abdominal thrombus, which was seen in 17% of patients with deep venous thrombosis.

Rituximab plus fludarabine was well tolerated and associated with an excellent complete response rate, including molecular remissions, in patients with low-grade or follicular lymphoma.

CT venous phase imaging at the time of CT pulmonary angiography is comparable with venous sonography in the evaluation of femoropopliteal DVT. The iliac veins and vena cava, vessels poorly shown on sonography but sometimes the source of significant pulmonary emboli, are also depicted by CT venography.

e19041 Background: Treatment of locally advanced unresectable (LAU) or metastaticCSCC (mCSCC) is sub-optimal with a paucity of robust data on systemic therapy. Platinum or fluorouracil-based chemotherapy is commonly used. This retrospective study aimed to evaluate the efficacy and outcomes of patients (pts) with LAU or mCSCC treated with systemic therapy. Methods: Records ofpts with CSCC treated with systemic therapy from Jan ‘01 – Jan ‘11 were reviewed. Response was assessed using WHO criteria. Descriptive results were assessed using Wilcoxon Rank Sum test for ordinal responses and Pearson Chi-square test for categorical responses. Survival was calculated by the Kaplan-Meier method. Results: Of 28 pts identified, 25 pts (M:F – 18:7), median age 66 yrs (39, 85) had required data for final analysis. 11 pts (44%) had facial primary tumors (including 7 of the external ear). 19 pts (76%) had LAU and 6 pts had mCSCC. 17 pts (68%) received multi-agent 1st-line chemotherapy (CT). 72%, 76% and 48% pts received platinum, taxane or cetuximab respectively as part of their regimens. 14 pts got 2nd line therapy and 4 pts received concurrent radiation therapy. Partial response (PR) was 44% and 24% pts had stable disease (SD) for a disease control rate of 68%. With a median follow-up of 42.8m, the median progression-free (PFS) and overall survival (OS) were 5.5m (2.3, 13.2) and 10.9m (5.3, 21.3) respectively; 3-yr OS was 22%. Pts with WHO response had improved PFS (20.8m; 4.4, NR; p<.0001) and OS (37.5m; 10.3, NR; p=.0003) compared to pts with SD/PD (PFS 2.7m; OS 5.9m). Use of platinum-based therapy significantly improved PFS and OS, while taxanes and cetuximab had no impact in this small cohort. 91% (n=10) of pts who had a PR received a platinum drug. There was no difference in PFS or OS between face and non-face primary site CSCC and multi-agent versus single agent therapy. Conclusions: Platinum-based therapy remains a standard option in advanced CSCC management. Agents to improve response rates are needed and future trials should address the role of other therapies in CSCC, including novel targeted and CT combinations.
