“…After full‐text examination, 18 were excluded because outcome data could not be extracted separately for patients receiving neoadjuvant treatment ( n = 4) or the article reported a mix of arterial and venous thrombotic events ( n = 14). Twenty‐eight records (19 full texts and nine abstracts) including a total study population of 7827 cancer patients (range 11 to 1398 patients) were finally included in the review (Table ) . All studies but two were single center and were conducted during a time period that spanned from 1994 to 2015.…”

Background Venous thromboembolism (VTE) is a frequent complication in cancer patients receiving adjuvant treatment. The risk of VTE during neoadjuvant chemo-radiotherapy remains unclear. Objectives This systematic review evaluated the incidence of VTE in patients with cancer receiving neoadjuvant treatment. Methods MEDLINE and EMBASE databases were searched from inception to October 2017. Search results were supplemented with screening of conference proceedings of the American Society of Clinical Oncology (2009-2016) and the International Society of Thrombosis and Haemostasis (2003-2016). Two review authors independently screened titles and abstracts, and extracted data onto standardized forms. Results Twenty-eight cohort studies (7827 cancer patients, range 11 to 1398) were included. Twenty-five had a retrospective design. Eighteen cohorts included patients with gastrointestinal cancer, representing over two-thirds of the whole study population (n = 6002, 78%). In total, 508 of 7768 patients were diagnosed with at least one VTE during neoadjuvant treatment, for a pooled VTE incidence of 7% (95% CI, 5% to 10%) in the absence of substantial between-study heterogeneity. Heterogeneity was not explained by site of cancer or study design characteristics. VTE presented as pulmonary embolism in 22% to 96% of cases (16 cohorts), and it was symptomatic in 22% to 100% of patients (11 cohorts). The highest VTE rates were observed in patients with bladder (10.6%) or esophageal (8.4%) cancer. Conclusions This review found a relatively high incidence of VTE in cancer patients receiving neoadjuvant therapy in the presence of some between-study variation, which deserves further evaluation in prospective studies.

“…Eight studies reported on the prevalence of VTE before the start of neoadjuvant treatment, which ranged between less than 1% up to 10% []. The clinical presentation of prevalent VTE was described only by Krepline and colleagues, who reported that 69% of these events were incidentally detected .…”

Neoadjuvant chemoradiation for rectal cancer is not associated with higher rates of thromboembolism

Abstract: The prevalence of TE in patients with rectal cancer was 7.8%, with most events occurring in within 30 days of surgery. Neoadjuvant chemoradiation was not associated with an increased risk of TE.
