          Abstract

          Taxanes are chemotherapeutic agents commonly used to treat several cancers. However, the effects of taxanes on advanced gastric cancer (AGC) are still not clear, especially when used as a first-line treatment. This systematic review and meta-analysis aims to investigate the efficacy and safety of taxanes as a first-line treatment of AGC. The quality of our included studies was assessed using the Cochrane risk of bias tool for RCTs and NOS scale for nRCTs, and the data of the included studies was of satisfactory quality to analyze. The outcomes included overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and toxicity. Taxanes significantly improved OS (HR = 0.84, 95% CI 0.76–0.92, P = 0.0004) and had a slight effect on ORR (RR = 1.23, 95% CI 1.00–1.51, P = 0.05). However, taxanes may also increase the risks of neutropenia and leucopenia, similar to effects observed in other conventional chemotherapeutic treatments such as oxaliplatin and epirubicin. Therefore, patient characteristics including concomitant diseases, physical condition, and prior therapies should be considered before selecting taxane-based treatments for AGC.

          Perineural invasion is an independent predictor of outcome in colorectal cancer.

          Daniel J. Wilks, H. Berger, Catherine Liebig … (2009)
          Perineural invasion (PNI) is associated with decreased survival in several malignancies, but its significance in colorectal cancer (CRC) remains to be clearly defined. We evaluated PNI as a potential prognostic indicator in CRC, focusing on its significance in node-negative patients. We identified 269 consecutive patients who had CRC resected at our institution. Tumors were re-reviewed for PNI by a pathologist blinded to the patients' outcomes. Overall and disease-free survivals were determined using the Kaplan-Meier method, with differences determined by multivariate analysis using the Cox multiple hazards model. Results were compared using the log-rank test. PNI was identified in less than 0.5% of the initial pathology reports. On rereview, 22% of tumors in our series were found to be PNI positive. The 5-year disease-free survival rate was four-fold greater for patients with PNI-negative tumors versus those with PNI-positive tumors (65% v 16%, respectively; P < .0001). The 5-year overall survival rate was 72% for PNI-negative tumors versus 25% for PNI-positive tumors. On multivariate analysis, PNI was an independent prognostic factor for both cancer-specific overall and disease-free survival. In a subset analysis comparing patients with node-negative disease with patients with stage III disease, the 5-year disease-free survival rate was 56% for stage III patients versus 29% for patients with node-negative, PNI-positive tumors (P = .0002). Similar results were seen for overall survival. PNI is grossly underreported in CRC and could serve as an independent prognostic factor of outcomes in these patients. PNI should be considered when stratifying CRC patients for adjuvant treatment.

            In vivo evaluation of polymeric micellar paclitaxel formulation: toxicity and efficacy.

            S. C. Kim, D. W. Kim, Y. H. Shim … (2001)
            Although the current clinical formulation of paclitaxel (Taxol) has a promising clinical activity against a wide variety of tumors, it has significant toxic side effects, some of which are associated with its formulation in a 1:1 (v/v) mixture of Cremophor EL and dehydrated alcohol. One of the problems associated with the intravenous administration of paclitaxel is its low solubility in water. Our study was designed to evaluate the pharmacokinetics, tissue distribution, toxicity and efficacy of a paclitaxel (Genexol)-containing biodegradable polymeric micellar system (Genexol-PM) in comparison to Taxol. Genexol-PM was newly developed by using a low molecular weight, nontoxic and biodegradable amphiphilic diblock copolymer, monomethoxy poly(ethylene glycol)-block-poly(D,L-lactide) (mPEG-PDLLA) and paclitaxel (Genexol, Samyang Genex Co., Seoul, Korea). In a human cancer cell line model, Genexol-PM and Taxol showed comparable in vitro cytotoxicity against human ovarian cancer cell line OVCAR-3 and human breast cancer cell line MCF7. The maximum tolerated dose (MTD) of Genexol-PM and Taxol in nude mice was determined to be 60 and 20 mg/kg, respectively. The median lethal dose (LD(50)) in Sprague--Dawley rats was 205.4 mg/kg (male) and 221.6 mg/kg (female) for Genexol-PM, while 8.3 mg/kg (male) and 8.8 mg/kg (female) for Taxol. After intravenous administration of Genexol-PM in murine B16 melanoma-induced female SPF C57BL/6 mice at a dose of 50 mg/kg, the area under the plasma concentration-time curve (AUC) was similar to Taxol((R)) at a dose of 20 mg/kg, but biodistribution of paclitaxel after administration of Genexol-PM showed 2 to 3-fold higher levels in tissues including liver, spleen, kidneys, lungs, heart and tumor as compared to Taxol. The in vivo antitumor efficacy of Genexol-PM as measured by reduction in tumor volume of SKOV-3 human ovarian cancer implanted in nude (nu/nu) athymic mice and MX-1 human breast cancer implanted in Tac:Cr:(NCr)-nu athymic mice was significantly greater than that of Taxol. The results of cytotoxicity, MTD, LD(50) and antitumor efficacy suggest that Genexol-PM may have a great advantage over present-day chemotherapy with Taxol.

              Taxol suppresses dynamics of individual microtubules in living human tumor cells.

              T. Jordan, P Wadsworth, A Yvon (1999)
              Microtubules are intrinsically dynamic polymers, and their dynamics play a crucial role in mitotic spindle assembly, the mitotic checkpoint, and chromosome movement. We hypothesized that, in living cells, suppression of microtubule dynamics is responsible for the ability of taxol to inhibit mitotic progression and cell proliferation. Using quantitative fluorescence video microscopy, we examined the effects of taxol (30-100 nM) on the dynamics of individual microtubules in two living human tumor cell lines: Caov-3 ovarian adenocarcinoma cells and A-498 kidney carcinoma cells. Taxol accumulated more in Caov-3 cells than in A-498 cells. At equivalent intracellular taxol concentrations, dynamic instability was inhibited similarly in the two cell lines. Microtubule shortening rates were inhibited in Caov-3 cells and in A-498 cells by 32 and 26%, growing rates were inhibited by 24 and 18%, and dynamicity was inhibited by 31 and 63%, respectively. All mitotic spindles were abnormal, and many interphase cells became multinucleate (Caov-3, 30%; A-498, 58%). Taxol blocked cell cycle progress at the metaphase/anaphase transition and inhibited cell proliferation. The results indicate that suppression of microtubule dynamics by taxol deleteriously affects the ability of cancer cells to properly assemble a mitotic spindle, pass the metaphase/anaphase checkpoint, and produce progeny.
