Factors related with symptom duration until diagnosis and treatment of symptomatic colorectal cancer.

Background: Colorectal cancer (CRC) survival depends mostly on stage at the time of diagnosis. However, symptom duration at diagnosis or treatment have also been considered as predictors of stage and survival. This study was designed to: 1) establish the distinct time-symptom duration intervals; 2) identify factors associated with symptom duration until diagnosis and treatment.

Primary melanoma of the adrenal gland: a case report and review of the literature.

Background: Primary melanoma of the adrenal gland is exceptionally rare as demonstrated by the few cases reported in the medical literature, and it has a high fatality rate. We present the case of a patient with two relapses and survival to date.

Case Report: We describe the case of a 58-year-old Caucasian woman who consulted her doctor with symptoms of asthenia, anorexia and weight loss.

Treatment of hepatocellular carcinoma in the transplant era.

Background: hepatocellular carcinoma (HCC) is one of the most frequent malignant diseases of the liver. It is clearly related to cirrhosis, especially to that caused by liverbound viruses. This study addresses the behavior of this disease in patients treated under different protocols at two third-level hospitals.

Diagnosis delay and follow-up strategies in colorectal cancer. Prognosis implications: a study protocol.

Background: Controversy exists with regard to the impact that the different components of diagnosis delay may have on the degree of invasion and prognosis in patients with colorectal cancer. The follow-up strategies after treatment also vary considerably. The aims of this study are: a) to determine if the symptoms-to-diagnosis interval and the treatment delay modify the survival of patients with colorectal cancer, and b) to determine if different follow-up strategies are associated with a higher survival rate.
