OBJECTIVE: To retrospectively compare treatment of hepatocellular carcinoma (HCC) with transarterial chemoembolization (TACE) using gelatin sponges or microspheres plus lipiodol-doxorubicin vs. doxorubicin-loaded drug-eluting beads (DEB). MATERIALS AND METHODS: A total of 158 patients with HCC received TACE from November 2010 to November 2011 were enrolled in this study, including 64 (40.5%) received TACE with lipiodol-doxorubicin and gelatin sponges (group A), 41 (25.9%) received TACE with lipiodol-doxorubicin and microspheres (group B), and 53 (33.5%) received TACE with doxorubicin-loaded DEB (group C). Tumor response and adverse events (AEs) were evaluated. RESULTS: No significant difference was found at baseline among the three groups. The doxorubicin dosage in group C was significantly (p < 0.001) higher compared to the dose used in groups A or B (median, 50 mg vs. 31 mg or 25 mg). Significantly (p < 0.001) more patients in group C achieved complete response compared to those in groups A or B (32.1% vs. 6.3% or 2.4%). Significantly (p < 0.001) less patients in group C had progressive disease compared to those in groups A or B (34.0% vs. 57.8% or 68.3%). Minor AEs were more common in groups A and B compared to group C, with rates of 54.7%, 34.1%, and 5.7%, respectively. CONCLUSION: In patients with HCC, TACE with DEB offers better safety and efficacy profiles compared to either TACE with gelatin sponges or TACE with microspheres.

BACKGROUND/AIMS: The predictive role of contrast-enhanced ultrasonography (CEUS) before performing transarterial chemoembolization (TACE) has not been determined. We assessed the possible predictive factors of CEUS for the response to TACE. METHODS: Seventeen patients with 18 hepatocellular carcinoma (HCC) underwent TACE. All of the tumors were studied with CEUS before TACE using a second-generation ultrasound contrast agent (SonoVue(R), Bracco, Milan, Italy). The tumor response to TACE was classified with a score between 1 and 4 according to the remaining enhancing-tumor percentage based on modified response evaluation criteria in solid tumors (mRECIST): 1, enhancing tumor <25%; 2, 25%< or =enhancing tumor<50%; 3, 50%< or =enhancing tumor<75%; and 4, enhancing tumor> or =75%). A score of 1 was defined as a "good response" to TACE. The predictive factors for the response to TACE were evaluated during CEUS based on the maximum tumor diameter, initial arterial enhancing time, arterial enhancing duration, intensity of arterial enhancement, presence of a hypoenhanced pattern, and the feeding artery to the tumor. RESULTS: The median tumor size was 3.1 cm. The distribution of tumor response scores after TACE in all tumors was as follows: 1, n=11; 2, n=4; 3, n=2; and 4, n=1. Fifteen tumors showed feeding arteries. The presence of a feeding artery and the tumor size (< or =5 cm) were the predictive factors for a good response (P=0.043 and P=0.047, respectively). CONCLUSIONS: The presence of a feeding artery and a tumor size of less than 5 cm were the predictive factors for a good response of HCC to TACE on CEUS.

BACKGROUND/AIMS: Among diffuse large B cell lymphoma (DLBCL) patients, determining the appropriate dose and chemotherapy schedule to balance toxicity and efficacy is harder in elderly than in younger patients. Moreover, there are no currently available clinical factors that consistently identify patients who are unfit to receive chemotherapy. Therefore, the clinical characteristics and outcomes of elderly patients with DLBCL and the causes of treatment-related death were investigated in this study. METHODS: The clinical characteristics and outcomes of 44 elderly (> or = 70 years of age) patients diagnosed with DLBCL between January 2005 and June 2013 were evaluated. Variable clinical data along with the response rate, overall survival (OS), and causes of treatment-related death or treatment interruption were investigated. RESULTS: The median OS was 18.6 months, and 19 patients completed curative treatment. The mean average relative dose intensity of adriamycin in patients who completed chemotherapy was 0.617, and of these patients, 16 achieved complete remission. Chemotherapy incompletion, infectious complications, ex tranoda l involvement, high lactate dehydrogenase, poor performance status, and low albumin level at diagnosis were related to a shorter OS. However, multivariate analysis revealed that only infections and chemotherapy incompletion were significantly related to poor prognosis. The most common cause of treatment-related death was infection, and patients who had experienced infectious complications tended to have lower albumin levels than those of patients without such complications. CONCLUSIONS: In the treatment of elderly lymphoma patients, the dose intensity of adriamycin is not as important as it is in young patients. However, in elderly patients, infections are particularly dangerous, especially in patients with low albumin levels.

OBJECTIVETo assess the efficacy of vinorelbine (NVB)-based regimens in patients with metastatic triple negative breast cancer (mTNBC) pretreated with anthracyclines and taxanes.

METHODSClinical data of 48 patients diagnosed and treated for mTNBC between 2004 and 2012 at the Cancer Hospital, Chinese Academy of Medical Sciences (CAMS) were retrospectively analyzed. All patients were pretreated with anthracyclines and at least one taxane in neo-adjuvant, adjuvant or chemotherapy for mTNBC and patients should be having at least one measurable metastatic lesion. Totally, 48 patients were included in this study, of which 21 cases received first-line chemotherapy and 27 cases received second-line chemotherapy. Based on the regimen they received, 22 patients were treated with NVB plus platinum (NP), and 26 patients with NVB plus capecitabine (NX).

RESULTSAfter 70 months follow-up, in the total group of patients, the objective response rate was 20.8%, clinical benefit rate was 43.8%, median progression free survival (PFS) was 4.4 months and median overall survival (OS) was 15.5 months. In addition, the ORR was significantly better in the NP arm versus NX arm (33.8% vs.7.7%, P=0.029) as well as PFS was statistically improved in the NP arm than NX arm (5.3 m vs. 3.0 m, P=0.023). Similar trend was observed in the OS, although the difference was not statistically significant (27.7 m vs. 14.8 m, P=0.077). In all, the most frequently reported adverse events were G1/2 gastrointestinal toxicity (68.8%) and neutropenia (62.5%) . No significant difference was observed between the NP arm and NX arm (P>0.05). The percentage of patients who delayed chemotherapy administration in the NP arm and NX arm was 9.1% (n=2), and 3.8% (n=1), respectively.

CONCLUSIONSNVB-based combination chemotherapy demonstrates moderate efficacy in mTNBC patients pretreated with anthracyclines and one taxane with manageable toxicity. NP regimen shows potential superiority over NX regimen, and should be further verified in randomized phase III clinical trial in larger cohort.

OBJECTIVETo explore the antitumoral effect of indirubin on androgen-independent prostate cancer PC-3 cells and its possible mechanisms.

METHODSWe measured the inhibitory effect of indirubin on the proliferation of prostate cancer PC-3 cells using MTT assay, detected their cell cycles by flow cytometry, and determined the expressions of the cell cycle regulatory protein cyclin D1 and its related downstream gene c-myc by Western blot.

RESULTSThe viability of the PC-3 cells was significantly decreased by indirubin in a concentration-dependent manner, reduced to 52. 2% and 13. 6% at 5 and 10 µmol/L, respectively. The cell cycle of the PC-3 cells was markedly inhibited by indirubin at 5 µmol/L, with the cells remarkably increased in the G0 and G1 phases and decreased in the S and G2/M phases. Meanwhile, indirubin also inhibited the expressions of cyclin D1 and c-myc in the Wnt signaling pathway.

CONCLUSIONIndirubin can suppress the proliferation of androgen-independent prostate cancer PC-3 cells, which may be associated with its inhibitory effect on the cell cycle and Wnt signaling pathway.

OBJECTIVETo evaluate the efficacy and safety of cisplatin and capecitabine combination (XP) therapy for patients with metastatic triple negative breast cancer (TNBC) progressing after anthracycline and taxane treatment.

METHODSTwenty-nine metastatic TNBC patients were prospectively enrolled to receive capecitabine (1, 000 mg/m(2) twice daily on days 1-14) and cisplatin (75 mg/m(2) on day 1) , repeated every 3 weeks.

RESULTSWith a median of 6 cycles of XP, all 29 patients were evaluable for response, including 18 PR (62.1%), 6 SD (20.7%), 5 PD (17.2%) and no CR. The response rate was 62.1%. Patients with earlier stage at diagnosis (stage I to IIIA), longer post-operative disease free survival (>2 years) and less metastatic sites (≤ 3) obtained significantly higher response rate than patients with later stage at diagnosis (stage IIIB to IV), shorter post-operative disease free survival (≤ 2 years) and more metastatic sites (>3). The leading side effects were grade 1/2 gastrointestinal and hematological toxicities. Grade 3/4 toxicities included neutropenia (34.5%), leukocytopenia (31.0%), anemia (6.9%), thrombocytopenia (3.4%), nausea/vomiting (20.7%), stomatitis (3.4%), and hand-foot syndrome (3.4%).

CONCLUSIONCisplatin and capecitabine combination therapy is an active and well-tolerated doublet treatment in metastatic TNBC patients progressing after anthracycline and taxane treatments.

Restenosis following vascular revascularization remains an important clinical problem. Local drug delivery which can provide enough drug concentration in the lesion location without causing adverse systemic effect is an excellent solution for this question. We conducted a systematic literatory search on PubMed and CKNI through May 2014. After reviewing all related papers, we provided a comprehensive overview of the available drugs and techniques for local drug delivery that have been developed to prevent restenosis after peripheral vascular interventions, including innovations that have been tested only in animals as well as those already approved for clinical use. In brief, anti-proliferative drugs such as paclitaxel and sirolimus are the most used and suitable drugs for local delivery system. Additionally, some promising drugs including anti-inflammatory drugs, antioxidant drugs and drugs inhibiting cell proliferation and migration are already being tested in pre-clinical trials or animal models. At the same time, intraluminal and extraluminal delivery devices have also got a rapid development during the past decades. The efficacy of drug-eluting stent, drug-eluting balloon, porous and microporous balloon and the most recent drug-eluting bioresobable scaffold for preventing of restenosis in peripheral vessels have been demonstrated in humans or in animals, some of them even have received the CE mark in Europe. Endovascular microinfusion catheter and drug-loaded perivascular wraps have only been tested in animal models, more researches are needed. With the development of pharmacology and bioengineering, great strides will be made in the prevention of restenosis in the near future.

PURPOSE: To investigate the inhibitory effect of 0.02% mitomycin C on eyelash regrowth when injected to the eyelash hair follicle immediately after radiofrequency ablation. METHODS: We prospectively included 21 trichiasis patients from June 2011 to October 2012. Twenty eyes of 14 patients were treated with 0.02% mitomycin C to the hair follicle immediately after radiofrequency ablation in group 1, while radiofrequency ablation only was conducted in ten eyes of seven patients in group 2. Recurrences and complications were evaluated until six months after treatment. RESULTS: One hundred sixteen eyelashes of 20 eyes in group 1 underwent treatment, and 19 (16.4%) eyelashes recurred. Eighty-four eyelashes of ten eyes in group 2 underwent treatment, and 51 (60.7%) eyelashes recurred. No patients developed any complications related to mitomycin C. CONCLUSIONS: Application of 0.02% mitomycin C in conjunction with radiofrequency ablation may help to improve the success rate of radiofrequency ablation treatment in trichiasis patients.
