Incidence, Risk Factor, Treatment and Overall Survival of Locoregionally Recurrent Colon Cancer...
Colonic NeoplasmsNeoplasm Recurrence1 moreData on disease recurrence was collected for all primary colon cancer patients diagnosed in the Netherlands over the first six months of 2015. Three-year cumulative incidence, risk factors, treatment and three-year OS of locoregionally recurrent colon cancer were determined.
SLNB After Neoadjuvant Treatment in Node Positive Patients
Sentinel Lymph Node BiopsyLocoregional Neoplasm Recurrence2 moreFrom May 2016 till May 2018 all breast cancer patients with operable disease submitted to surgery after neoadjuvant treatment would be divided in four groups considering initially clinical axillary stage, axillary procedure that was done, axillary response to preoperative systemic treatment and pathological axillary stage. In first postoperative year all patients will be monitored for appearance of locoregional and distant recurrence.
Screening MRI for Cancer Recurrence in Patients Treated With Breast Conserving Therapy
Breast NeoplasmsNeoplasm Recurrence1 moreA prospective, multicenter study: Primary objective: to assess the diagnostic yield of screening MRI compared to physical examination, mammography or ultrasonography in the detection of recurrence in patients treated with breast conserving therapy Secondary objective: to describe the size, type, grade, and nodal status of cancers seen only on MRI and to estimate the rate of benign biopsies and short interval follow-up induced only by MRI in this population.
PET-MRI After Radiofrequency Ablation (RFA) or Microwave Ablation (MWA)
Liver NeoplasmsLocal Neoplasm RecurrenceThe primary objective of this study is to evaluate the ability of PET-MRI and to detect a local site recurrence during the first year of follow-up after RFA or MWA of colorectal liver metastases (CRLM) as compared with contrast enhanced (ce) CT and PET-CT. Standard reference will be clear focal uptake in the rim of the lesion on PET-CT, possibly in combination with histology (when available) or clinical follow-up. Secondary outcomes are the inter-observer variability, the ability to diagnose new intrahepatic lesions and in what way PET-MRI is able to influence future treatment compared to PET-CT and ceCT. The patients satisfaction concerning the PET-MRI will be examined with a questionnaire.
