Preoperative staging of rectal cancer with MR Imaging: correlation with surgical and histopathologic findings.
Rectal cancer is a common malignancy that continues to have a highly variable outcome, with local pelvic recurrence after surgical resection usually leading to incurable disease. The success of tumor excision depends largely upon accurate tumor staging and appropriate surgical technique, although the results of recent surgical trials indicate that evaluation of the involvement of the mesorectal...
متن کاملadditional value of diffusion-weighted imaging to evaluate prognostic factors of breast cancer: correlation with the apparent diffusion coefficient
results a low adc value was associated with lymph node metastasis (p < 0.01) and with high ki-67 protein levels (p = 0.03). there were no significant differences in the adc values among the histological grade (p = 0.48), molecular subtype (p = 0.51), tumor size (p = 0.46), and p53 protein level (p = 0.62). conclusion the pre-operative use of the 3.0 tesla dwi could provide information about the...
متن کاملParaneoplastic Pyoderma Gangrenosum Associated with Rectal Adenocarcinoma
Pyoderma gangrenosum (PG) is a rare chronic neutrophilic dermatosis characterized by painful necrotic ulceration. The most common diseases associated with PG are inflammatory bowel disease, certain rheumatologic and hematologic diseases, and malignancy. Here, we describe the case of a 60-year-old man who presented with pruritic and painful erythematous ulcerative macules and patches on both low...
متن کاملDiffusion Kurtosis Imaging in Prostate Cancer
Introduction: Diffusion weighted imaging (DWI) and the calculated apparent diffusion coefficient (ADC) is showing potential for improving detection of prostate cancer (PCa), as the increased cellularity of many tumors is associated with restricted water diffusion and thus with a decreased ADC [1,2]. The ADC assumes Gaussian water diffusion and is calculated by monoexponential fitting. However, ...
متن کامل[Prognostic factors and functional imaging in rectal cancer].
The outcome of treatment for rectal cancer in recent years has been improved by diverse advances in the field of surgery and in neoadjuvant oncologic therapies. Heald's introduction of the concept of the mesorectum as an anatomical unit (total mesorectal excision) in 1982 and the generalization of preoperative radiochemotherapy have improved the prognosis in a significant number of patients. Ow...
