| Summary: | Introduction. Cancer-associated hypercoagulability was an underlying factor of high mortality of cancer due to venous thromboembolism. Chemotherapy is proposed as one of the contributing factors of the hypercoagulable state. We aim to evaluate the change of coagulation status, which was marked by D-dimer level, in cancer patients receiving chemotherapy.
Methods. This is a prospective cohort study in Indonesian national cancer center which involves all adult histologically-confirmed-cancer patients who started chemotherapy between May and July 2018. The coagulation status is assessed by plasma of D-dimer level. We measured D-dimer before chemotherapy and one week after chemotherapy. Paired t-test was performed to assess the significant difference in D-dimer levels before and after chemotherapy.
Results. A total of 89 patients fulfilled the eligibility criteria, of whom 74.2% were female and almost half of total subjects (44.9%) were breast cancer patients. Majority of subjects (69.6%) were stage III or stage IV cancer. There were 12.4% of subjects received cisplatin-based chemotherapy. There was a marginally significant difference in plasma level of D-dimers before and after chemotherapy (p = 0.05). We also found significant differences between D-dimer level before and after chemotherapy in stage III patients (t(35) = 2.48, p = 0.02) and stage IV patients (t(25) = 2.14, p = 0.04). There was no significant difference between D-dimer level before and after chemotherapy in stage I and stage II patients. Subgroup analyses based on chemotherapy agents showed that there was significant D-dimer change in cisplatin-based chemotherapy subjects (t(10) = 2.31, p = 0.04), but not in non-cisplatin-based chemotherapy subjects (t(77) = 1,50, p = 0.14).
Conclusion. Compared to before chemotherapy, there is a significant difference of coagulation status marked by plasma D-dimer level one week after chemotherapy, particularly in patients with stage III or stage IV cancer and in patients receiving cisplatin-based chemotherapy. |
