ABSTRACT
Objective: To evaluate vascular endothelial growth factor (VEGF) levels in hepatocellular carcinoma patients before and after transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) and its relation to treatment response. Methods: A total of 40 patients with unrespectable hepatocelluar carcinoma were assessed clinically. Twenty patients were suitable to be treated by TACE, while other 20 patients were treated with PEI. Serum VEGF levels were measured before and 1 month after each procedure by ELISA. Response was assessed after 1 month according to Union Internationale Contre le Cancer evaluation criteria based on change in tumor size as measured by ultrasound. Results: There was no significant difference between TACE and PEI groups with regard to age, sex, tumor size, response to local therapy, or VEGF and alpha-fetoprotein before and after therapy. VEGF levels after TACE were significantly higher than before TACE [(298.1 ± 123.6) pg/mL vs. (205.8 ± 307.3) pg/mL; P = 0.001]. Also, VEGF levels were significantly higher after PEI than before PEI [(333.8 ± 365.6) pg/mL vs. (245.3 ± 301.8) pg/mL; P = 0.000]. Non-responders of both groups had significantly high VEGF levels than responder's, both before [(985.0 ± 113.2) pg/mL vs. (117.1 ± 75.3) pg/mL; P < 0.001] and after therapy [(1. 330.6 ± 495.7) pg/mL vs. (171.0 ± 94.7) pg/mL; P = 0.000)]. Conclusions: Both TACE and PEI were associated with an increase in serum VEGF in hepatocelluar carcinoma patients. Higher levels of VEGF before and after therapy were found in non-responders, suggesting that VEGF is a useful marker in predicting treatment response.
ABSTRACT
Many patients with relapsed metastatic breast cancer are pre-treated with taxanes and anthracyclines, which are usually given in the neoadjuvant/adjuvant setting or as first-line treatment for metastatic disease. The primary objective of this study was to determine the overall response rate for combination treatment with gemcitabine and cisplatin in patients with locally advanced or metastatic breast cancer who had relapsed after receiving one adjuvant/neoadjuvant or first-line metastatic chemotherapy regimen containing an anthracycline with/without a taxane. Secondary endpoints included duration of response, time to progression, one-year survival probability, and toxicity. A single-arm, open-label, phase 2 study conducted at 1 7 investigative sites in Egypt. Treatment consisted of gemcitabine [1250 mg/m[2]] on Days 1 and 8 and cisplatin [70 mg/m[2]] on Day 1 of each 21-day cycle. Treatment continued until disease progression or a maximum of 6 cycles. Of 144 patients all were evaluable for safety and 132 patients were evaluable for efficacy. The overall response rate was 33.3% and 45.5% of the patients with stable disease as their best response. The median time to progression was 5.1 months and the one-year survival probability was 73%. The most common grade 3/4 adverse events were nausea/vomiting [20.1%], neutropenia [19.4%], anemia [13.9%], asthenia [11.1%], diarrhea [9.7%], stomatitis [7.6%], leucopenia [7.6%], and thrombocytopenia [6.2%]. Twelve [8.3%] patients had serious adverse events. The results of this study indicate that gemcitabine and cisplatin were active and generally well tolerated in pretreated patients with locally advanced or metastatic breast cancer
ABSTRACT
These recommendations provide a data-supported and based-evidenced approach to the screening, diagnosis, staging and treatment of Egyptian patients with hepatocellular carcinoma [HCC] in which we tried to construct an Egyptian algorithm for our Egyptian HCC patients in terms of type and timing of surveillance, readily available diagnostic tools that suit our means and the proper and efficient timely treatment that suits our resources. They are based on the experience of the authors in the specified topic and the AASLD Policy on the Development and Use of Practice Guidelines. These recommendations suggest preferred approaches to screening [for early detection of cases with hepatic nodule and/or elevated AFP], diagnosis [for accurate diagnosis of HCC cases], staging [for detection of specific category of treatment according the patient's general condition] and treatment [selection of the most suitable treatment option for the patient after his proper evaluation]. In an attempt to characterize the quality of evidence supported recommendations, the Egyptian Guidelines requires a category to be assigned and reported with each recommendation [Table I]
