RESUMEN

INTRODUCTION: Prostate cancer is the most prevalent malignant neoplasia among men worldwide. Several prognostic factors, including Gleason's score, the measurement of serum prostate-specific antigen (PSA) and the evaluation of the percentage of fragments affected by cancer on prostate biopsy, have already been established. Age alone, however, has yet to be studied as a prognostic factor independently from other known factors. The aim of the present study was to compare the characteristics and the evolution of prostate cancer in different age groups using a paired analysis for patients with equivalent known prognostic factors. In addition, we aimed to determine the true impact of age on the prognosis of prostate cancer. MATERIAL AND METHODS: The data from 2,283 patients subjected to radical retropubic prostatectomy between 1998 and 2009 were reviewed. The patients were divided into three age groups: < 55 years old, between 56 and 65 and > 65 years old. Each patient was matched to another patient in the other groups who had the same PSA range (< 4.0, between 4.0 and 10.0 and > 10), Gleason score on the surgical specimen and prognostic range of positive fragments in the prostate biopsy (< 33%, between 34 and 50% and > 50%). After pairing, each group consisted of 215 patients, who were compared using the biochemical recurrence of the disease (PSA > 0.2), the interval for biochemical relapse, extra-capsular invasion and invasion of the seminal vesicles or the lymph nodes. RESULTS. No significant difference was observed between the groups regarding the frequency of relapses, interval of relapse, extra-capsular invasion and invasion of the seminal vesicles or lymph nodes. DISCUSSION: None of the studied factors were affected by the age of the patients. Therefore, patients of different ages had tumors with similar characteristics and behaviors. CONCLUSION: When assessed separately, without the effects of the main prognostic factors, age does not appear to be an independent prognostic factor for prostate cancer.

RESUMEN

Splenic tumors are not frequent. Blood vessel neoplasms are a rare category of tumors and have an extremely low incidence in the spleen. This case report aims to describe a 57-year-old woman in whom a routine imaging examination had shown splenic cysts. During her follow-up, the cysts became larger and increased in number. A diagnostic splenectomy was performed and its analysis showed a rare splenic angiosarcoma.

RESUMEN

BACKGROUND: Therapeutic decisions in recurrent oral and oropharyngeal squamous carcinoma (SCC) remain controversial. METHODS: Two hundred forty-six consecutive patients who underwent salvage surgery for recurrent squamous cell carcinoma (SCC) of the oral cavity and oropharynx were studied. The tumor sites were lip, 33 cases; oral cavity, 143; oropharynx, 70. The previous treatment was surgery in 73 patients, radiotherapy in 96, combined surgery and radiotherapy in 76, and chemotherapy in one. The clinical stage of recurrence was I/II in 51 cases and III/IV in 195 cases. The disease-free interval (DFI) was less than 1 year in 156 cases and greater than 1 year in 90 cases. RESULTS: The rate of recurrence was 54.9%, and the overall 5-year actuarial survival rate was 32.3%. The significant prognostic factors in multivariate analysis were restage (p = .049) and DFI (p = .045). CONCLUSION: Patients with recurrent oral and oropharyngeal SCC at initial clinical stages (rCS I and II) and with a DFI greater than 1 year had a favorable prognosis.
