Several factors are reportedly associated with the occurrence of thrombosis. We aimed to describe the prevalence and the anatomoclinical features of IPT observed in cancer patients who were treated in a medical oncology department in Tunisia.Methods: A total of 600 cancer patients who had port implantation from January 2013 to December 2015 were retrospectively identified. Cases with symptomatic/incidental IPT (radiologically confirmed) were further identified. Epidemiological and anatomoclinical features were collected from patient records and the department database.Results: We observed that 33 of the 600 patients had IPT; thus, the prevalence was 5.5%. The median age was 57 years, and the gender ratio was 0.43. Overweight or obesity was observed in 73% of the patients. IPT occurred mainly in patients with breast (36.4%) and colorectal (33.3%) cancers, which were mostly nonmetastatic (79%). At least one identified classical thromboembolic risk factor was found in 13 patients (smoking in 9, tamoxifen in 2). IPT was symptomatic in 93% of the cases, occurring within an average time of 56 days. Implantable ports were removed because of infection in 2 cases and nonfunctionality in 3 cases. IPT treatment was based on low-molecular-weight heparins (94%) and antivitamin K (6%) for an average of 130 days. Four patients had post-therapy complications: one thrombosis recurrence and three infections.Conclusions: IPT cases in the 600 patients were observed to occur in obese nonmetastatic cancer patients within the first 3 months after IP implantation.
