Ferumoxide-enhanced magnetic resonance imaging techniques in pre-operative assessment for colorectal liver metastases.

Aim: The objective was to evaluate whether contrast-enhanced magnetic resonance imaging (MRI) techniques used in a pre-operative assessment protocol for colorectal liver metastases are as accurate as spiral computer tomography during arterial portography (CTAP). Pre-operative accuracy and clinical consequences of MRI are described and compared with CTAP. Moreover, post-operative survival rate and tumour recurrence were studied.

Controlled introduction of the sentinel node biopsy in breast cancer in a multi-centre setting: the role of a coordinator for quality control.

Aims: It is proposed that sentinel node biopsy should replace axillary lymph-node dissection. We analysed the role of a coordinator in the introduction of the sentinel node biopsy in breast cancer in a multi-centre setting to assure standardization and quality control.

Methods: We included 232 operable breast cancer patients.

Lymphedema and lymphocysts following lymphadenectomy may be prevented by omentoplasty: A pilot study.

Objectives: Pelvic lymph node dissection as part of the staging surgery for cervical carcinoma interrupts the afferent lymphatics, so the lymph drains retroperitoneally. New surgical techniques designed to leave the peritoneum open after the retroperitoneal dissection, in particular the application of a pedicled omentoplasty along the dissection route, have been advocated to prevent the formation of lymphocysts and lymphedema. We investigated the possible benefit of pedicled omentoplasty in preventing lymphocysts and lymphedema following pelvic lymph node dissection.

The value of ultrasound with ultrasound-guided fine-needle aspiration biopsy compared to computed tomography in the detection of regional metastases in the clinically negative neck.

Purpose: Head and neck oncologists have not reached consensus regarding the role of contemporary imaging techniques in the evaluation of the clinically negative neck in patients with head and neck squamous cell carcinoma (HNSCC). The purpose of the present study was to compare the accuracy of ultrasound with guided fine-needle aspiration biopsy (UGFNAB) and computed tomography (CT) in detecting lymph node metastasis in the clinically negative neck.

Methods And Materials: Sixty-four neck sides of patients with HNSCC were examined preoperatively by ultrasound/UGFNAB and CT at one of five participating tertiary care medical centers.

CT-guided bone biopsy in a cancer center: experience with a new apple corer-shaped device.

In this article we report our experience with CT-guided bone biopsy (CTGBB) using a new nondisposable bone biopsy device with in a uniform protocol for all lesions and compare our results with data from bone biopsies obtained with other techniques. With this biopsy device, the specimen is collected in a 20 x 2 mm chamber of an apple corer-shaped needle. In 46 consecutive cancer patients that were candidates for bone biopsy, 50 CTGBB procedures were performed and analyzed.
