Background: Chemotherapy in colorectal cancer is usually administered as continuous infusion of 5-fluorouracil, often in combination with oxaliplatin or irinotecan. Targeted drugs are most efficient and tolerable in conjunction with con- tinuous infusion dosing. Implanted venous access devices (VAD) are the prerequisite for continuous infusion admini- stration. The reported catheter migration frequency with VAD is 0% - 3.5%. The purpose of this case-control study was to evaluate the predisposing factors of catheter migration. Methods: We inserted VADs in 88 radically operated colo- rectal cancer patients randomized to adjuvant 48-hour-infusion chemotherapy repeated every 14 days, altogether 12 times over 24 weeks. Three out of 88 patients (3.4%) had a symptomatic catheter migration from the superior caval vein into the internal jugular vein. The fourth case had chemotherapy for osteosarcoma. These 4 cases were compared with 12 controls from the same 88 patient study population, matched for age, sex, body mass index (BMI), physical activity level and right subclavian insertion site. Tip position, port model, complications, catheter length and material was stud- ied. The post insertion catheter tip position in the chest X-ray was numbered from 1 (in subclavia) to 8 (in atrium). Re- sults: The four cases, all male, had a median position of 3 (range 3 - 4) and controls 6 (range 4 - 8), P = 0.004, median difference 3 (CI95% 1 - 5). At notification of migration the patients had experienced discomfort in the neck region start- ing 5 to15 days before at strenuous upper extremities activity with Valsalva maneuvers. Conclusion: Optimal catheter tip position when sitting is in the right atrium or low in the superior vena cava to avoid migration. Patients with VADs should avoid strenuous activity with Valsalva maneuvers
