Surgery by doctors with little experience has 70 percent worse rate of prostate cancer recurrence. 外科医生缺乏经验，有70 ％的税率差前列腺癌复发。

Sloan-Kettering Cancer Center - According to a new study published online in the Journal of the National Cancer Institute , prostate cancer patients treated by highly experienced surgeons are much more likely to be cancer-free five years after surgery than patients treated by surgeons with less experience.斯隆-凯特林癌症中心的癌症-根据一项新的研究发表在网上杂志上的美国国家癌症研究所，前列腺癌患者的治疗具有丰富经验的外科医生更容易受到癌症免费五年后比手术治疗外科少经验。

“The difference in outcome among patients who were treated by surgeons with varying degrees of experience is clinically relevant and likely reflects a true relationship between surgical technique and cancer control,” said the study’s lead author Andrew Vickers, PhD, Associate Attending Research Methodologist, Memorial Sloan-Kettering Cancer Center (MSKCC). "差别在结果中的病人治疗外科医师不同程度的经验是有关的临床及可能反映了真实的关系，外科技术及癌症防治， "说，这项研究的主要作者郑的vickers ，博士，副出席产物研究，纪念斯隆-凯特林癌症中心癌症中心（ mskcc ） 。

Many studies have examined the relationship between surgical experience and patient outcomes.许多研究已审阅关系外科经验和耐心的结果。 However, it is often unclear whether the findings are related to differences in surgical technique or result from differences in clinical variables or tumor characteristics.不过，它常常不清楚结果，是与不同的外科技术，或因不同临床变量或肿瘤特性。 In the current study, the researchers adjusted for cancer severity, so that differences among surgeons likely reflect differences in the techniques they use rather than just differences in the patients they see.在这次研究中，研究人员调整为癌症的严重性，使分歧外科可能反映了不同的技术，他们使用，而不只是在不同的病人，他们看到的。

Investigators analyzed the cancer outcomes of 7,765 prostate cancer patients who were treated with radical prostatectomy - surgical removal of the prostate - by one of 72 surgeons at four major US academic medical centers over a 16-year period.调查分析癌症成果7765前列腺癌的病人，治疗前列腺癌根治-手术切除前列腺-一位72外科四大美国学术医疗中心超过16年。 Sophisticated statistical models were used to evaluate the link between the total number of prostatectomies performed by the surgeon prior to each patient’s operation and biochemical recurrence of prostate cancer (defined as a rising PSA level of more than 0.4 ng/mL).先进的统计模型被用来评估之间的联系总数前列腺手术，由外科医师之前，每个病人的手术和生化复发前列腺癌（定义为一个崛起港务集团水平超过0.4微克/毫升） 。

The results showed that the risk of recurrence five years after surgery was 17.9 percent for patients treated by surgeons who had performed 10 operations and 10.7 percent for patients treated by surgeons who had performed 250 operations.结果表明，复发危险五年手术后为17.9 ％ ，治疗外科医生进行了10个业务和10.7 ％ ，为治疗外科医生进行了250行动。 This means that patients treated by inexperienced surgeons were nearly 70 percent more likely to have a recurrence of their prostate cancer than those who were treated by surgeons with greater experience.这意味着，治疗经验的外科医师中，近七成更可能有复发的前列腺癌比那些治疗外科更多的经验。 According to the analysis, one out of every 14 patients treated by an inexperienced surgeon will have a recurrence.据分析，每14例治疗经验的外科医生将有复发。

The results were described in terms of a learning curve, which showed a dramatic improvement in cancer control with increasing surgical experience up to 250 prior operations; however, there was no large change in recurrence rates with additional surgical experience.结果用语描述一个学习曲线，显示了明显改善癌症防治随着外科经验上升到250事先作业;但是，没有大的变化，在复发率与附加手术经验。

“The learning curve is steep and did not start to plateau until a surgeon had completed 250 prior operations,” said the study’s senior author, Peter Scardino, MD, Chairman, Department of Surgery, MSKCC. "学习曲线是陡峭的，没有开始，直到高原外科已完成250行动之前说： "这项研究的资深作者，彼得皮尔逊堡，全部手术， mskcc 。 “Surgeons with little experience get significantly poorer results than those who have more.” "外科经验很少得到明显较差结果比那些有更多" 。

“Our results provide support for what other studies have implied - that good technique is learned and increased volume leads to improved outcomes,” said Dr. Vickers. "我们的研究结果提供支持，有什么其他的研究也暗示-好的技术经验和量的增加会导致更好的成果，说： "博士的v ickers。 “However, our focus on cancer outcome, the size of the difference in outcome associated with increasing surgical experience, and the large number of cases required before the learning curve starts to plateau, suggests that more serious attention should be paid to the issue of surgical quality.” "然而，我们的重点放在癌症成果，其规模差别的结果与增加手术经验，并开展了大量的案件之前需要学习曲线开始高原表明，较严重的应注意的问题手术质量。 "

The researchers note that the surgical technique of experienced surgeons may differ from that of surgeons with less experience.研究者指出外科技术经验的外科医生可能不同于外科经验较少。 They conclude that further research is needed to determine how surgical technique might differ between these groups and to identify the critical aspects of radical prostatectomy that are associated with improved cancer control.他们的结论还需要进一步研究以确定如何外科技术可能不同，这些团体并找出关键方面前列腺癌根治，都与改善癌症控制。

“Although the successful practice of surgery presumes a lifetime of learning, the large number of cases required before the learning curve plateaus suggests the need to expand opportunities for training in surgical technique for surgeons in the early years after residency training,” said Dr. Scardino. "虽然成功实践手术假定终生学习，大量案件需要，然后学习曲线高原表明有必要扩大培训机会，在外科技术的外科医生在最初几年后，住院医师训练，博士说： "观看。
