Over the past couple of decades considerable progress has been made in the management of metastatic colorectal cancers(mCRC) leading to a significant improvement in five-year survival. Although part of this success has been rightly attributed to aggressive surgical management and advances in other adjunct treatments, our understanding of the pathogenesis of cancer and emergence of newer molecular targets for colon cancer has created a powerful impact. In this review article we will discuss various targeted therapies in the management of mCRC. Newer agents on the horizon soon to be incorporated in clinical practice will be briefly reviewed as well.

An effect of heating and stirring in a facile wet chemical route to synthesize entangled nanofibrous mesh of doped polyaniline(PANI) was reported. The structural, morphological, and optical properties of PANI nano-fibers were found to be dependent on synthesis temperature and stirring. The XRD analysis confirms nano PANI formation with 2θ peaks around 15°, 21°, and 25° for(011),(020), and(200) crystal planes, respectively. The average crystallite size varies between 25 nm to 60 nm due to change in synthesis conditions. The SEM analysis reveals the clustered granule formation for PANI sample synthesized at 28 and 60 ℃ under continuous stirring, whereas, unstirred synthesis at 60 ℃ shows entangled nano-fibrous mesh morphology. The TGA study shows better thermal stability for PANI mesh over granular PANI. The FTIR spectra validates the emeraldine salt PANI formation with peaks corresponding to C-H, C-N, N=Q=N, N=B=N, and N-H vibration bands. The UV-Vis analysis shows the major absorbance peaks around λ: 340 nm(π-π* transition of benzenoid ring), and λ: 800 nm(π-π*, polaron-π*, π-polaron transitions). The dense entangled nano-fibrous coating of PANI synthesized at 60 ℃ without stirring shows highest electrical conductivity of 3.79 S·cm^-1.

BACKGROUND There is no remedial strategy other than definitive chemoradiotherapy for patients with advanced esophageal squamous cell carcinoma(ESCC) who are not eligible to undergo surgical *** To introduce a novel therapy called endoscopic debulking resection(Ed R) followed by additive chemoradiotherapy(CRT) and evaluate its efficacy and *** Advanced, inoperable ESCC patients between 1 January 2015 and 30 December 2019 were investigated retrospectively. Patients who received Ed R followed by CRT were deemed the Ed R + CRT group and those without CRT were deemed the Ed R group. Overall survival(OS), progression-free survival(PFS), and adverse events were *** A total of 41 patients were enrolled. At a median follow-up of 36 mo(range: 1-83), the estimated 1-, 2-, and 3-year cumulative OS rates of patients who underwent Ed R plus additive CRT were 92.6%, 85.2%, and 79.5%, respectively, which were higher than those of patients who underwent Ed R alone(1-year OS, 83.3%;2-year OS, 58.3%;3-year OS, 50%;P = 0.05). The estimated 2-year cumulative PFS rate after Ed R + CRT was 85.7%, while it was 61.5% after Ed R(P = 0.043). According to the univariate and multivariate Cox regression analyses, early clinical stage(stage ≤ IIB) and additive CRT were potential protective factors for cumulative OS. No severe adverse events were observed during the Ed R procedure, and only mild to moderate myelosuppression and radiation pneumonia were observed in patients who underwent additive CRT after Ed *** Ed R plus CRT is an alternative strategy for selective advanced inoperable ESCC patients.
