RESUMEN
Bevacizumab(BV)combination chemotherapy in colorectal cancer under subcutaneously implanted central venous port (CVP)implantation may cause complications after the implantation. Measurement of D-dimer is recommended to predict thromboembolism and other complications, but its relevance to complications after CVP implantation remains unclear. In this study, we investigated the association between D-dimer and complications after CVP implantation in 93 patients with colorectal cancer who received BV combination chemotherapy. Complications after CVP implantation occurred in 26 patients (28%), and those with VTE showed higher D-dimer values at the onset of the complication. The D-dimer values of the patients with VTE displayed a sharp increase at the onset of the disease, while those with an abnormal CVP implantation site showed a more variable course. Measurement of D-dimer levels appeared useful in estimating the incidence of VTE and abnormal CVP implantation sites in post-CVP implantation complications of BV combination chemotherapy for colorectal cancer. Further, monitoring not only the quantitative values but also the fluctuations over time is also important.
