近年来,前列腺癌的发生率有明显上升的趋势,前列腺癌与前列腺增生症的关系也逐渐受到重视。临床上前列腺癌多为60岁以上老年人,病程相对较长,伴有血尿、下腹痛比率较高。直肠指诊:前列腺癌多为坚硬结节,前列腺增生症表面多光滑、质韧、有弹性。9例前列腺癌和168例前列腺增生症中上,前者伴有腺上皮细胞不典型增生发生率和程度均较后者显著,前列腺癌患者的前列腺组织内多有增生的结节状改变,有的结节内可有部分癌变组织或正常前列腺组织,说明前列腺癌和前列腺增生症有一定的形态学联系。因前列腺增生受压于包膜下外周区域的萎缩腺组织未被切除时,可使前列腺增生复发或癌变,应引起临床重视。  相似文献

BackgroundInnovations in treatments, imaging, and molecular characterisation in advanced prostate cancer have improved outcomes, but there are still many aspects of management that lack high-level evidence to inform clinical practice. The Advanced Prostate Cancer Consensus Conference (APCCC) 2019 addressed some of these topics to supplement guidelines that are based on level 1 evidence.ObjectiveTo present the results from the APCCC 2019.Design, setting, and participantsSimilar to prior conferences, experts identified 10 important areas of controversy regarding the management of advanced prostate cancer: locally advanced disease, biochemical recurrence after local therapy, treating the primary tumour in the metastatic setting, metastatic hormone-sensitive/naïve prostate cancer, nonmetastatic castration-resistant prostate cancer, metastatic castration-resistant prostate cancer, bone health and bone metastases, molecular characterisation of tissue and blood, inter- and intrapatient heterogeneity, and adverse effects of hormonal therapy and their management. A panel of 72 international prostate cancer experts developed the programme and the consensus questions.Outcome measurements and statistical analysisThe panel voted publicly but anonymously on 123 predefined questions, which were developed by both voting and nonvoting panel members prior to the conference following a modified Delphi process.Results and limitationsPanellists voted based on their opinions rather than a standard literature review or formal meta-analysis. The answer options for the consensus questions had varying degrees of support by the panel, as reflected in this article and the detailed voting results reported in the Supplementary material.ConclusionsThese voting results from a panel of prostate cancer experts can help clinicians and patients navigate controversial areas of advanced prostate management for which high-level evidence is sparse. However, diagnostic and treatment decisions should always be individualised based on patient-specific factors, such as disease extent and location, prior lines of therapy, comorbidities, and treatment preferences, together with current and emerging clinical evidence and logistic and economic constraints. Clinical trial enrolment for men with advanced prostate cancer should be strongly encouraged. Importantly, APCCC 2019 once again identified important questions that merit assessment in specifically designed trials.Patient summaryThe Advanced Prostate Cancer Consensus Conference provides a forum to discuss and debate current diagnostic and treatment options for patients with advanced prostate cancer. The conference, which has been held three times since 2015, aims to share the knowledge of world experts in prostate cancer management with health care providers worldwide. At the end of the conference, an expert panel discusses and votes on predefined consensus questions that target the most clinically relevant areas of advanced prostate cancer treatment. The results of the voting provide a practical guide to help clinicians discuss therapeutic options with patients as part of shared and multidisciplinary decision making.  相似文献

Background

In advanced prostate cancer (APC), successful drug development as well as advances in imaging and molecular characterisation have resulted in multiple areas where there is lack of evidence or low level of evidence. The Advanced Prostate Cancer Consensus Conference (APCCC) 2017 addressed some of these topics.

Objective

To present the report of APCCC 2017.

Design, setting, and participants

Ten important areas of controversy in APC management were identified: high-risk localised and locally advanced prostate cancer; “oligometastatic” prostate cancer; castration-naïve and castration-resistant prostate cancer; the role of imaging in APC; osteoclast-targeted therapy; molecular characterisation of blood and tissue; genetic counselling/testing; side effects of systemic treatment(s); global access to prostate cancer drugs. A panel of 60 international prostate cancer experts developed the program and the consensus questions.

Outcome measurements and statistical analysis

The panel voted publicly but anonymously on 150 predefined questions, which have been developed following a modified Delphi process.

Results and limitations

Voting is based on panellist opinion, and thus is not based on a standard literature review or meta-analysis. The outcomes of the voting had varying degrees of support, as reflected in the wording of this article, as well as in the detailed voting results recorded in Supplementary data.

Conclusions

The presented expert voting results can be used for support in areas of management of men with APC where there is no high-level evidence, but individualised treatment decisions should as always be based on all of the data available, including disease extent and location, prior therapies regardless of type, host factors including comorbidities, as well as patient preferences, current and emerging evidence, and logistical and economic constraints. Inclusion of men with APC in clinical trials should be strongly encouraged. Importantly, APCCC 2017 again identified important areas in need of trials specifically designed to address them.

Patient summary

The second Advanced Prostate Cancer Consensus Conference APCCC 2017 did provide a forum for discussion and debates on current treatment options for men with advanced prostate cancer. The aim of the conference is to bring the expertise of world experts to care givers around the world who see less patients with prostate cancer. The conference concluded with a discussion and voting of the expert panel on predefined consensus questions, targeting areas of primary clinical relevance. The results of these expert opinion votes are embedded in the clinical context of current treatment of men with advanced prostate cancer and provide a practical guide to clinicians to assist in the discussions with men with prostate cancer as part of a shared and multidisciplinary decision-making process.  相似文献

Purpose

We determined whether the clinical and pathological features of hereditary prostate cancer differ from those of sporadic prostate cancer.

Materials and Methods

We compared the clinical and pathological features of radical prostatectomy specimens from 50 men with and 50 without a family history of prostate cancer who were matched for age and date of surgery.

Results

Median serum prostate specific antigen concentration was not significantly different in the 2 groups. Mean Gleason score plus or minus standard deviation in the 50 men with sporadic prostate cancer was 6.2 plus/minus 1 compared to 5.6 plus/minus 0.9 in those with hereditary disease (p = 0.008). Of the 50 hereditary and 50 sporadic prostate cancers 35 (70 percent) and 33 (66 percent), respectively, were pathologically organ confined (p = 0.69). Median percentage of carcinoma within the gland (determined morphometrically) in men with hereditary disease was 11.4 plus/minus 8.3 compared to 10.9 plus/minus 8.9 for those with sporadic cancer (p = 0.63).

Conclusions

In our study population hereditary prostate cancers have significantly lower Gleason scores compared to sporadic carcinomas. Otherwise, there appear to be no substantial clinical or pathological differences.  相似文献
