Brief Summary

Currently, lymph node dissection is standard of care during prostatectomy of intermediate risk tumors at the Martini Clinic. It allows the assessment of possible but unlikely lymph nodes metastases. In case of lymph node metastasis, depending on the number of affected lymph nodes, an adjuvant radiation with or without additional hormone therapy may be discussed in order to stop or delay further progression of the disease. Since the procedure carries additional risks, it is controversial. The risks include prolonged surgery duration, injury of vessels and nerves, as well as disorders of lymphatic circulation after surgery. Moreover, formation of lymphoceles (accumulation of lymph fluid in the tissue) are common, which may result in soft tissue swelling, thrombosis, inflammation and additional surgical procedures. Therefore, the aim of this study is to evaluate whether the removal of the lymph nodes during prostatectomy positively influences the course of the disease in patients with intermediate risk prostate cancer, or if the lymph node dissection does not have any influence on the recurrence of the disease and therefore further therapies. In this case, the omission of lymph node dissection may avoid an unnecessary expansion of the operation and the potentially associated side effects linked to it. This is particularly of interest considering the rapidly advancing technical possibilities, both in imaging and in the treatment of prostate cancer, since this enables an earlier and more individual intervention in the case of recurrence.

Outcome Measures

Primary Outcomes (1)

  • PSA recurrence rate

    The PSA recurrence rate in patients with intermediate risk prostate cancer treated with radical prostatectomy with or without additional lymph node dissection at three years of follow up (PSA recurrence: PSA value ≥ 0.2 ng / ml).

    36 months after surgery

Secondary Outcomes (3)

  • Incidence of lymphoceles and complications

    6 months after surgery

  • quality of life including continence and potency

    6, 12, 24, 36 months after surgery

  • metastasis-free survival

    36 months

Study Arms (2)

extended lymph node dissection

ACTIVE COMPARATOR

Patients randomized to arm A undergo bilateral lymph node dissection in the pelvic area as part of prostatectomy. At least 10 lymph nodes must be removed.

Procedure: lymph node dissection

standard without lymph node dissection

NO INTERVENTION

Application of standardized surgical technique without extensive lymph node dissection. If, contrary to expectation, intraoperative suspicion of lymphogenic metastasis results, a lymph node dissection is performed and the patient is excluded from the study (freedom of the surgeon).

Interventions

At least 10 lymph nodes must be removed.

extended lymph node dissection
