Active clinical trials for "Neoplasm Recurrence, Local"

Data 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.

From 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.

A 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.

The 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.

The purpose of this study is to determine whether cylindrical abdominoperineal resection is effective in the treatment of advanced very low rectal cancer
