A Rare Case of Metastatic Hepatocellular Carcinoma to the Hard Palate.

Extrahepatic metastasis of hepatocellular carcinoma (HCC) to the head and neck is unusual, especially the oral cavity/maxillofacial region. Metastatic HCC to the hard palate, however, is particularly rare. The most common site of HCC metastasis is the lung, followed by lymph nodes, bone, and adrenal gland. Importantly, oral cavity metastatic HCC may be misdiagnosed as a primary malignancy, such as a salivary gland carcinoma. In this article, we describe a young woman with metastatic HCC to the hard palate that was initially diagnosed as an acinic cell carcinoma.

Gleason Score Evolution and the Effect on Prostate Cancer Outcomes.

OBJECTIVES: We evaluated how the changes in Gleason grading affected the long-term outcomes of a large prostatectomy cohort. METHODS: We obtained long-term follow-up (16.7 years) in 581 patients having undergone radical retropubic prostatectomy between 1985 and 1995. We excluded those with seminal vesicle and/or lymphatic involvement. We regraded the specimens according to contemporary guidelines and compared how this affected outcomes compared with their original (pre-1995) Gleason scoring. In total, 499 patients were evaluable. RESULTS: A Gleason score of 6 or less declined from 73% to 29%, and the number increased from 25% to 63% for a Gleason score of 7 and from 5% to 8% for a Gleason score of 8 to 9. As a result, for a Gleason score less than 7, biochemical failure decreased from 28% to 23%, metastatic disease 5% to 2%, and prostate cancer death from 5% to 3%. The same results were 50% to 37%, 11% to 7%, and 10% to 6% for a Gleason score of 7 and 86% to 71%, 43% to 32%, and 29% to 26% for a Gleason score more than 7, respectively. With the most recent grade grouping, for groups 1 to 5, biochemical failure occurred in 23%, 32%, 45%, 69%, and 78%, respectively. Metastatic disease occurred in 2%, 4%, 12%, 24%, and 56%, respectively. Prostate cancer-related death occurred in 2%, 4%, 9%, 21%, and 44%, respectively. CONCLUSIONS: The revised Gleason scores improved the outcomes in all risk groups. Based on Gleason score, patients with prostate cancer will appear to have better outcomes than they did before 2005, making any comparison tenable. The current grading system shows a consistent increased risk in biochemical failure, metastatic disease, and prostate cancer-related death with each successive grade.

Long-Term Follow-Up after Prostatectomy for Prostate Cancer and the Need for Active Monitoring.

BACKGROUND: Only truly long-term follow-up can determine the ultimate outcome in prostate cancer. Most studies have a median follow-up of less than 10 years and then project outcomes out to 15 and 20 years. We sought to follow patients for at least 20 years. Materials and Methods. We followed 754 prostate cancer patients treated with radical prostatectomy from 1988 to 1995 for a median follow-up (in survivors) of 23.9 years. We excluded lymph node and seminal vesicle positive patients and an additional 47 patients that did not have baseline prostate-specific antigen (PSA). This left 581 patients for analysis. RESULTS: With the factors of PSA, Gleason score, and extraprostatic extension/margin positivity, we could partition patients into three risk groups for biochemical failure (low, intermediate, and high). In further analysis, we found that the risk of metastatic disease in the first two groups was almost identical (4% and 5%, respectively), while it was 19% in the high-risk group. High-risk patients were those with PSA >20 ng/ml and/or Gleason >7, or Gleason 7 + PSA 10-20 + epe (and or margin) positive. They had a 22% prostate cancer mortality. CONCLUSION: In patients with truly long-term follow-up after prostatectomy for prostate cancer, the risk of metastatic disease and cancer death is very low. Patients with the lower risk findings do not appear to benefit from routine follow-up after 10 years free of biochemical recurrence. With a higher risk of later failure, we recommend that the higher risk patients be followed at least intermittently for another 5 years (out to 15 years).

Mantle cell lymphoma of the prostate gland treated with holmium laser enucleation.

Mantle cell lymphoma of the prostate is rare and is seldom encountered in general urologic practice. It either arises primarily from the prostate or is a result of metastatic spread from another site. This specific type of lymphoma has an aggressive course and may respond poorly to traditional chemotherapy with frequent relapses. Mantle cell lymphoma occurs in middle age or older, which is also when symptoms of benign prostatic enlargement begin in men. This overlap makes the diagnosis of lymphoma of the prostate difficult and makes the treatment more complex. We describe a case of mantle cell lymphoma of the prostate that caused significant enlargement and bladder outlet obstruction with urinary retention. The obstruction was treated with holmium laser enucleation of the prostate with good functional results.
