To minimize the recurrence of a previously treated neoplasm in organ recipients, a period of 2 to 5 years without recurrence is advocated for most malignancies. However, prostate cancer is different because of its biological properties, diagnosis, and treatment. Most prostate cancers are detected at a low stage and demonstrate slow growth after detection. Definitive treatment with radical prostatectomy affords excellent results. Renal transplant candidates with early-stage prostate cancer have a higher risk of dying on dialysis than dying from prostate cancer; therefore, renal transplant candidates with organ-confined prostate cancer should be immediately considered for transplant.

Objectives: Locoregional therapy may decrease the tumor stage and enable liver transplant in patients who have hepatocellular cancer. The purpose of the present study was to assess the relation between locoregional therapy and recurrence of hepatocellular carcinoma after transplant. Materials and Methods: In 50 patients who had liver transplant for treatment of end-stage liver disease from hepatocellular carcinoma and cirrhosis, outcomes were evaluated for associations with locoregional therapy before transplant and Milan criteria. Results: Most patients had locoregional therapy before transplant (31 patients [62%]: transarterial catheter radiofrequency ablation alone, 16 patients; chemoembolization alone, 10 patients; both transarterial catheter radiofrequency ablation and chemoembolization, 5 patients). Follow-up at median 90 months after transplant showed that 9 patients (18%) had recurrence at median 45 months (range, 120 +/- 12 mo) (recurrence: locoregional therapy, 5 of 31 patients [16%]; no locoregional therapy, 4 of 19 patients [21%]; not significant). Locoregional therapy was associated with a significantly lower frequency of recurrence in patients who were outside the Milan criteria. Conclusions: In patients who have liver transplant for treatment of hepatocellular carcinoma, preoperative locoregional therapy may decrease recurrence in patients who are outside the Milan criteria.

(2018) Avci, Tevfik; Karakayali, Feza; Yabanoglu, Hakan; Moray, Gokhan
Purpose: The aim of this study was to compare the efficacy and early-late results of subtotal parathyroidectomy and total parathyroidectomy/auto transplantation without cryopreservation conducted on cases with secondary hyperparathyroidism (HPT). Materials and Methods: 68 patients with secondary HPT who had parathyroidectomy were analysed retrospectively. In group1 (n=47) subtotal parathyroidectomy, in group2 (n=21) total parathyroidectomy/auto transplantation without cryopreservation were performed in our clinic. Patients' demographic characteristics and clinical features were evaluated. Results: In group1 8 patients (14.9%), in group2 17 patients (76.2%) had concurrent thymectomies. The rates of persistant HPT in group1 and group2 were 14.9% (n=7), 4.8% (n=1) respectively. In group2 no recurrent HPT was seen, in group2 10.6% (n=5) of the patients had recurrent HPT. The reasons of persistent and recurrent HPT were ectopic or supernumerary glands in 69.2% (n=9) of the patients. Conclusion:. In patients with end stage renal failure and secondary HPT, bilateral cervical thymectomy concurrent with total parathyroidectomy/auto transplantation without cryopreservation can be applied as a safe and efficient surgical procedure.

Introduction: Hemorrhage is a challenging complication of pelvic surgery. This study aimed to analyze the causes, management and factors associated with morbidity in patients experiencing major pelvic hemorrhage during complex abdomino-pelvic surgery.Methods: Patients who had major intraoperative pelvic hemorrhage during complex abdomino-pelvic surgery at 11 tertiary referral centers between 1997-2017 were included. Patient characteristics, management strategies to control bleeding, short and long term postoperative outcomes were evaluated retrospectively.Results: There were 120 patients with a mean age of 56.6 +/- 2.4 years and a mean BMI of 28.3 +/- 1 kg/m(2). While 104 (95%) of the patients were operated for malignancy, 16(5%) of the patients had surgery for a benign disease. The most common bleeding site was the presacral venous plexus 90(75%). Major pelvic hemorrhage was managed simultaneously in 114(95 %) patients. Electrocauterization 27(23%), pelvic packing 26(22%), suturing 7(6%), thumbtacks application 7(6%), muscle welding 4(4%), use of energy devices 2(2%) and topical hemostatic agents 2(2%) were the management tools. Combined techniques were used in 43(36%) patients. Short-term morbidity and mortality rates were 48(40%) and 2(2%), respectively. High preoperative CRP levels(p=0.04), history of preoperative radiotherapy (p=0.04), longer bleeding time (p=0.006) and increased blood transfusion (p=0.005) were the factors associated with postoperative morbidity.Discussion/Conclusion: Postoperative morbidity related to major pelvic hemorrhage can be reduced by optimizing the risk factors. Prehabilitation prior to surgery to moderate inflammatory status and prompt action with proper technique to control major pelvic hemorrhage can prevent excessive blood loss in complex abdomino-pelvic surgery.

Biliary complications are major sources of morbidity after liver transplant due to vulnerable vascularization of the bile ducts. Biliary complications are the "Achilles' heel" of liver transplant with their high incidence, need for repeated and prolonged treatment, and potential effects on graft and patient survival. Although standardization of reconstruction techniques and improvements in immunosuppression and organ preservation have reduced the incidence of biliary complications, in early reports the morbidity rates are 50%, with related mortality rate 25% to 30%. Prophylaxis is a major issue. Although many risk factors (old donor age, marginal graft, prolonged ischemia time, living-donor liver transplant, partial liver transplant, donation after cardiac death, hepatic arterial thrombosis, organ preservation, chronic rejection, and other donor and recipient characteristics) do not directly affect biliary complications, accumulation of the factors mentioned above, should be avoided. However, no accepted standard has been established. Treatment strategy is a subject of debate. Recently, non-operative treatment of biliary complications have been preferred for diagnosis and therapy, because percutaneous or endoscopic treatment may prevent the need for surgical intervention. In this study, we reviewed our treatment of early and late biliary complications after liver transplant.
