Prostate cancer: what about reproducibility of decision made at multidisciplinary team management?

PURPOSE: The prostate cancer (PCa) treatment is multimodal. Thus multidisciplinary team management (MDTM) decision-making process appears as a tool to answer all aspects of PCa treatment. Our aim was to evaluate the reproducibility of therapeutic decisions made at MDTM. MATERIALS AND METHODS: We compared therapeutic decisions of PCa by presenting the same file of patient under a fake identity after 6 to 12 months from the first presentation. Forty-nine files of radical prostatectomy (RP) (28 pT2, 21 pT3) performed for clinical localized PCa were represented at MDTM which included urologist, oncologist, pathologist and radiologist. Analysis of therapeutic decisions comprised criteria such as: TNM stage, Gleason score, margin status and comorbidities. The reproducibility was assessed statistically by Kappa coefficient. RESULTS: Study subjects included 49 patients who underwent radical prostatectomy (RP). The mean age was similar in pT2 and pT3 groups (P = .09). The mean serum PSA value was 8.32 ng/mL (range, 3.56-19.5) in pT2 group and 9.4 ng/mL (range, 3.8-22) in pT3 group. The margin status in pT2 and pT3 groups was positive in 25.0% and 47.6%, respectively. The decisions made at first and second MDTM for pT2 group were the same in 100% of cases with a perfect kappa coefficient (k = 1). In the group of pT3 (n = 21), the decisions were different in 33% at the second MDTM in comparison to the first MDTM. Especially for pT3b only 29% were reproducible decision with a slight agreement (k = 0.1). Concerning pT3a, 86% of the decisions were reproducible with a substantial agreement (k = 0.74). CONCLUSION: We showed a reliability and reproducibility of decision made at MDTM when guidelines are well defined. The therapeutic attitudes were less reproducible in locally advanced PCa but decision concerning those cases should be made in the setting of guidelines.

Accuracy of ultrasonography in diagnosis of testicular rupture after blunt scrotal trauma.

OBJECTIVES: The aim of this study is to determine the accuracy of ultrasonography for the diagnosis of testis rupture after scrotal trauma and its sensitivity and specificity for testis rupture, tunica albuginea breach, testicular hematoma, testis avulsion, epididymis injuries, and hematocele. METHODS: Between 1996 and 2006, 33 patients underwent surgical exploration for blunt scrotal trauma. All these patients had an emergency scrotal ultrasonography with the use of a 7.5 or 10 MHz linear transducer. Ultrasonographic findings were compared with surgical findings to calculate sensitivity and specificity of ultrasonography for each type of lesion. RESULTS: Of 33 patients, 16 presented a testis rupture. Testis rupture was in all cases suspected ultrasonographically by the loss of contour of the testis and heterogeneous parenchyma. Tunica albuginea breach was visualized in only 8 patients. Sensitivity and specificity of ultrasound for testis rupture were 100% and 65%, respectively. Moreover, ultrasonography allowed diagnosis of hematocele (sensitivity: 87% and specificity: 89%), testicular hematoma (sensitivity: 71%, specificity: 77%), and testis avulsion (sensitivity: 100%, specificity: 97%). Ultrasonography results for epididymis injuries were poor. On 7 patients, 3 epididymis lesions were misdiagnosed by ultrasound examination. CONCLUSIONS: Ultrasonography can distinguish various scrotal injuries. Testicular rupture is probably the most severe injury that needs early surgical treatment to improve testis salvage rate. In our work, ultrasonography is highly sensitive in the diagnosis of testis rupture and can provide information on the scrotal contents integrity that can help the physician to determine the optimal treatment.

[Vascular prostheses and renal transplantation]. / Protheses vasculaires et transplantations rénales.

OBJECTIVE: To evaluate the complications, the morbidity and mortality of renal transplantation in patients with a vascular prosthesis inserted either prior to or at the same time as renal transplantation. PATIENTS AND METHOD: Between January 2001 and January 2006, six renal transplantations were performed in patients with arterial vascular prostheses or requiring concomitant insertion of a vascular prosthesis during renal transplantation. The mean age was 58 years [range: 47-69 years]. In each case, we evaluated operative difficulties, complications and postoperative course (morbidity, mortality) and the renal functional result. RESULTS: The mean operating time was 230 minutes [range: 130-380 minutes] with a mean blood loss of 390 ml [175-750 ml]. Three patients required another surgical operation for femoral thrombosis, iliofemoral thrombosis and compressive haematoma. The median length of hospital stay was 21 days [range: 9-78 days]. Graft function was restored immediately in all six patients, and one case of graft loss was observed. The morbidity was higher than that usually observed after renal transplantation. With a mean follow-up of 26 months, the vascular and renal results are satisfactory. CONCLUSION: Renal transplantation in patients with a history of vascular prosthesis or requiring replacement of the vascular prosthesis at the same time as renal transplantation can be performed with satisfactory results but with an increased morbidity. The vascular treatment must be part of a multidisciplinary strategy in the context of transplantation.

[Atypical cysts and risk of renal cancer: value and danger of the Bosniak classification]. / Kystes atypiques et risque de cancer du rein. Intérêt et "danger" de la classification de Bosniak.

OBJECTIVE: The objective of this study was to devaluate the risk of renal cancer in patients with atypical renal cysts and to compare radiological data used to establish the Bosniak classification with clinical or histological data. MATERIAL AND METHOD: We performed a retrospective study on 37 patients managed in our establishment for atypical renal cyst between January 1995 and April 2003. The following criteria were analysed: gender, age, clinical examination and circumstances of discovery imaging findings, Bosniak classification, treatment modalities and follow-up data. These criteria were compared in two populations according to the presence or absence of associated renal cancer. RESULTS: In this series, 6 patients presented a stage II cyst. No cancer was demonstrated in this group of cysts. Ten patients presented a stage IIF cyst and 2 cancers were detected in this group (i.e. 20%). Fourteen patients presented a stage III cyst, with a cancer in 4 cases (30%) and 7 patients presented a stage IV cyst with 6 cancers (86%). CONCLUSION: The Bosniak classification is currently the reference classification fr the diagnosis of cystic diseases of the kidney. Although stages I and II (cysts with minor changes not requiring surveillance) and stages III and IV (suspicious malignant cysts which require surgical exploration) raise few diagnostic problems, stage IIF (indeterminate cyst requiring radiological surveillance) may be the source of diagnostic difficulties with a risk of missing an associated renal cancer.
