Radical retropubic and perineal prostatectomy for clinically localised prostate cancer in renal transplant recipients.

Abstract Objective: To analyse the functional and oncological outcome of consecutive renal-transplant recipients (RTRs) with clinically localised prostate cancer who underwent radical retropubic (RRP) or perineal (RPP) prostatectomy. Patients and methods: Between January 2000 and July 2011 16 patients underwent RRP (group 1) and seven RPP (group 2). In all, 200 consecutive non-RTRs served as the control group, of whom 100 each underwent RRP and RPP, respectively. The mean (range) interval between renal transplantation and RP was 95 (24–206) months, the PSA at the time of diagnosis was 4.5 (3.0–17.5) ng/mL, and the mean patient age was 64 (59–67) years. Results: The mean follow-up was 39 (RRP) and 48 months (RPP). There was no deterioration in graft function. In group 1, 13 and three patients had pT2a-cpN0 and pT3a-bpN0 prostate cancer, respectively, with a Gleason score of 6, 7 and 8 in 11, three and one patients, respectively. In group 2, three and four patients had pT2a-c and pT3a-b disease, respectively, with a Gleason score of 6 and 7 in two and five, respectively. In both groups one patient had a positive surgical margin and was followed expectantly, and all patients have no evidence of disease. Wound infections developed more often in the RPP group (29% vs. 7%), but there were no Clavien grade III–V complications. All patients achieved good continence, and two need one pad/day. Conclusions: RRP and RPP are suitable surgical treatments for prostate cancer in RTRs. RRP might be preferable, as it has the advantage of simultaneous pelvic lymphadenectomy and a lower risk of infectious complications.

Melatonin secretion following brain midline irradiation is diminished, but not correlated with subjective sleep disturbances

Cranial irradiation for brain tumours or leukaemias has been related to cognitive, endocrine and psychosocial late effects as well as sleep disturbances and increased daytime sleepiness. Studies suggest that cranial irradiation might impact on pineal melatonin secretion. Melatonin is an important regulator in human circadian rhythms and the sleep‐wake cycle. The objective of this study was to investigate melatonin secretion, subjective sleep parameters and their interplay in a cohort of cranially irradiated head and brain tumour and leukaemia survivors at least 3 years after radiotherapy.

The role of salvage extended lymph node dissection (LND) in patients with rising PSA and PET/CT scan detected nodal recurrence of prostate cancer.

242 Background: According to the risk constellation recurrence rate of prostate cancer following local therapy is up to 60%. Early salvage radiotherapy already showed a benefit in progression-free survival. We analyzed the impact of salvage extended lymph node dissection on cancer control in patients with rising PSA and nodal recurrence in PET/CT scan. Methods: Between 2003 and 2015 we performed a salvage extended lymph node dissection in 95 patients with rising PSA and nodal recurrence in PET/CT scan after previous local therapy for prostate cancer. The extent of resection field was adjusted to the pre-operative imaging. Results: We identified 95 patients with rising PSA and nodal recurrence in PET/CT scan with a mean age of 66 years (55-76 years). There were no significant intraoperative complications. Postoperatively, 12% had Clavien/Dindo grade 3 complications. Complete PSA response, defined as a postoperative PSA level < 0.2 ng/ml, was diagnosed in 36% of patients. With a median follow-up of 19 month...

Surgical management of testicular cancer patients with complex postchemotherapy residual masses: Aachen University experience.

387 Background: Post-chemotherapy retroperitoneal lymphadenectomy (PC-RPLND) represents the treatment of choice in patients with residual masses following chemotherapy for advanced non-seminomatous testicular germ cell tumors (NSGCT). Involvement of the abdominal aorta, the inferior vena cava or the thoracic/lumbar spine are rare but need complete resection for curative intent. We report on our single center experience in the management of such complex cases. Methods: Between January 2009 and September 2014 post-chemotherapeutic retroperitoneal lymph node dissection (PCRPLND) was performed in 162 patients (pts) with advanced NSGCT. Fourteen pts (4.9%) fulfilled the criteria of a GTS: enlarging metastatic mass in the retroperitoneum or visceral organs during systemic chemotherapy with normalized or regredient tumor markers. In all cases of GTS a complete radical bilateral PCRPLND including the resection of adjacent visceral and vascular structures was performed. Results: Median patient age was 24.5 (18 to ...

Vascular anomalies in patients undergoing retroperitoneal lymph node dissection.

382 Background: Anomalies of the renal vessels usually are clinically silent and might depicted during CT scanning of the abdomen for staging purposes of urological malignancies. Awareness of these rare anomalies is crucial especially in patients undergoing staging for germ cell tumors in order to avoid overstaging and unnecessary therapy. We report on the incidence of renal vessel anomalies in an unselected group of patients undergoing retroperitoneal lymph node dissection (RPLND) for testis cancer. Methods: 245 patients with testicular germ cell tumors underwent primary or secondary RPLND following inductive chemotherapy. Prior to RPLND, all patients underwent abdominal staging by CT scans or by MRI in selected cases. CT scans were reviewed with regard to the detection of vascular anomalies of the vena cava inf., renal veins, renal arteries, and iliac vessels. CT findings were correlated with intraoperative findings. Results: Overall, vascular anomalies were encountered in 39 patients (15.9%): retroaort...

Complications during cisplatin-based primary chemotherapy in patients with testicular cancer: Is there a need for thromboembolic prophylaxis?

371 Background: Cisplatin-based chemotherapy is an integral part of the multimodal therapy of patients with testicular cancer. The purpose of this analysis is to evaluate the chemotherapy associated side effects of primary treatment in a modern patient cohort and to correlate them to clinical stage and IGCCCG risk profile. Methods: We retrospectively analyzed charts of patients with testicular cancer in our institution from January 2003 until today. A total of 88 patients received systemic treatment, among those 74 as a primary treatment with 2 to 4 cycles of PEB. Side effects had been categorized according to the Common Terminology Criteria for Adverse Events (CTCAE), version 4. Results: 46 of 74 patients receiving PEB had at least one side effect. The most common side effects were haematotoxic with leucopenia in 34 (45.9%), febrile neutropenia in 10 (13.5%), gastrointestinal in 22 (29.7%), and thromboembolic events in 10 (14.8%) of the patients including three therapy associated deaths. Adverse events i...
