The significantly superior TTP and survival achieved with the addition of capecitabine to docetaxel 75 mg/m(2), with the manageable toxicity profile, indicate that this combination provides clear benefits over single-agent docetaxel 100 mg/m(2). Docetaxel/capecitabine therapy is an important treatment option for women with anthracycline-pretreated MBC.
These studies demonstrated the clinical benefits of nepafenac 0.3% over vehicle in reducing the risk of postoperative ME, with the integrated analysis showing improved BCVA after cataract surgery in patients with diabetic retinopathy, with no unanticipated safety events.
570 Introduction: Capecitabine (Xeloda [X]) shows synergy with taxanes and adding X to docetaxel (T) extends overall survival (OS), response rate (RR) and progression free-survival (PFS) beyond T alone. Sequential single-agent therapy could confer convenience benefits and may be more appropriate than combination chemotherapy for some pts. Methods: Pts with anthracycline-pretreated MBC received 3-weekly cycles of 1 of the following regimens: X→taxane (X 1250mg/m2 bid d1–14, followed after progression (PD) by T 100mg/m2 or paclitaxel [P] 175mg/m2 day 1; X+P (X 825mg/m2 bid days 1–14 + P 175mg/m2 day 1) or X+T (X 825mg/m2 bid days 1–14 + T 75mg/m2 day 1). Results: Of the 368 pts enrolled, 91 are either still on therapy or not evaluable. The table shows baseline characteristics, efficacy and safety in evaluable pts. Median follow up is 15.5 months. Median doses for X in each arm (1st cycle vs. 8th cycle, mg/m2 bid): 1218 vs. 1054; 948 vs. 900; 846 vs. 751. Median doses for P and T (1st cycle vs. 8th cycle, mg/m2): 173 vs. 169 and 75 vs. 72, respectively. In the X→taxane arm, 58 pts (64%) received sequential taxane; the remainder did not receive a taxane, either because they were still on X, had CR or had rapid PD. Conclusions: RR is higher with XP and XT, but PFS and OS are similar at a median follow-up of 15.5 months. All regimens were well tolerated with minimal grade 4 AEs. Because there is no clear superiority of sequential vs. combined therapy, pt characteristics are likely to be used to decide which regimen is the most appropriate. [Table: see text] [Table: see text]
627 Background: Concurrent chemoradiotherapy is the standard treatment in locally advanced rectal cancer. Bevacizumab and cetuximab are accepted today in the treatment of metastatic colorrectal cancer. We evaluate the activity and security of these drugs in the neoadyuvante setting. Methods: Ten patients have been included so far. Treatment consists in a first phase with induction treatment with capecitabine 2,000 mg/m2 D1-14, oxaliplatin 130 mg/m2 and bevacizumab 7.5 mg/kg every 3 weeks for two cycles. In sequential form a second phase that consist in external beam radiation therapy that was given at 50.4 Gy in 28 sesions concurrently with capecitabine 1,300 mg/m2 /d continuous during radiotherapy with cetuximab 400 mg/m2 every two weeks in patients with k-ras wild type. Results: 10 patients completed induction treatment and eight patients completed the concurrent phase. As of today, two patients are still on treatment. At this point, four patients have been operated; three patients are still waiting for surgery, and one avoided surgery. During induction treatment the main toxicity was disesthesias in eight patients, four patient presented grade 2 emesis, two presented grade 2 altered liver function test, two had grade 2 hand foot syndrome. One patient presented grade 3 hemorrhage. During the second phase, eight patients received cetuximab and presented rash grade 1-2, diarrhea grade 1 in five patients, emesis grade 1 in four patients, anemia grade 2 in two patients, proctitis grade 2 in four patients, and grade 3 in one patient. From four patients who were operated two presented complete pathological response and two have tumor persistence. Conclusions: The combination of chemoradiation with bevacizumab and cetuximab seems to be secure with no increment in toxicity and those presented are acceptable and manageable. No significant financial relationships to disclose.
