Utility of 18F-FDG PET and contrast-enhanced CT scan in the assessment of residual liver metastasis from colorectal cancer following adjuvant chemotherapy.
Neoadjuvant chemotherapy has been successfully used in the treatment of patients with colorectal liver metastases. The selection of patients for surgical resection after chemotherapy still poses a significant clinical challenge. (18)F-FDG PET is a useful tool in the assessment of liver metastases but the data regarding its sensitivity after chemotherapy is scarce. Our aim was to assess the value of this imaging modality in the selection of patients with colorectal liver metastasis for surgery following adjuvant chemotherapy. ⋯ These results suggest that (18)F-FDG PET and CT scan have sub-optimal sensitivity in the evaluation of colorectal liver lesions after neo-adjuvant chemotherapy, especially for lesions < 1 cm. The combined use of the two imaging techniques does not significantly increase the sensitivity of lesion detection.

Randomized Controlled Trial Multicenter StudyInternational Czech and Slovak cooperation in the treatment of patients with differentiated thyroid cancer.
The aim of this paper is to present our experience concerning cooperation in the treatment of Slovak patients with differentiated thyroid cancer in Slovak and Czech hospitals. The objectives of this study were to demonstrate the means of this cooperation and the results of therapy. ⋯ The results of this multi-centre study show that international Czech and Slovak cooperation in the complex therapy of patients with differentiated thyroid cancers is successful, with high efficacy. The treatment results were very similar to therapeutic results in our patients from the Czech Republic.

The aim of the study was to evaluate the usefulness of 18F-FDG-PET in patients with gastric lymphoma, in particular those affected by mucosa-associated lymphoid tissue (MALT) type and aggressive gastric non-Hodgkin's lymphoma (NHL). ⋯ Our data demonstrate the significant accuracy of 18F-FDG-PET in detecting active disease in gastric lymphoma of both MALT and non-MALT NHL type. A higher SUV value appears to be related to a more aggressive disease.

Clinical TrialUse of Tc99m-nanocolloid for sentinel nodes identification in cervical cancer.
The initial draining lymph node for a primary tumor is referred to as the "sentinel" node. Firstly adopted in the management of patients with cutaneous melanoma and breast cancer, it is now widely tested in cervical cancer. In patients with cervical cancer, lymph node status is the most important prognostic factor for survival. In patients with cervical cancer FIGO stage I and II pelvic lymph node metastases are expected in 0-16 and 24.5-31% and para-aortic lymph node metastases are expected in 0-22 and 11-19% of patients. The removal of pelvic and para-aortic lymph nodes is essential for assessing the biology of the disease. Lymphoscintigraphy enables the visualisation of lymphatic drainage patterns from a great variety of tumour sites prior to surgery. Therefore, the current procedure is to perform the pre-operative mapping of sentinel nodes by static and/or dynamic lymphoscintigraphy, followed by in vivo identification using a gamma detection probe and selective surgical resection. ⋯ A combination pre-operatively administered radioactively labelled albumin with blue dye allows the successful detection of SN in patient with cervical cancer. This technique will result in a real advance in the less aggressive management of patients with early stage cervical cancer. Sentinel lymph node status may be representative of the pelvic lymph nodes status in cervical cancer and thus could provide important information for further treatment.
