Liver transplantation for primary or metastatic sarcoma to the liver.

Sarcoma is generally a rare disease in the US, with poor survival in patients with both primary angiosarcoma and metastatic disease from sarcoma and GIST. In order to determine if liver transplantation for sarcoma is a realistic option, we examined records of all patients in the US component of the Israel Penn International Transplant Tumor Registry were reviewed. Those patients with liver failure from primary or metastatic liver sarcoma were evaluated. Patient outcome analysis was then performed. Patient and tumor demographics were reviewed as well as patient survival after transplantation. 19 patients are identified having received liver transplantation after treatment for sarcoma of the liver, 6 patients with primary hepatic sarcoma and 13 patients with metastatic sarcoma of the liver. Recurrence was almost universal in 18 of 19 patients (95%) after a median interval of 6 months. Survival for the group as a whole was 47% for 1-year, 15% for 3-years and 5% for 5-years. Given the early recurrence of tumor and meager 1-year survival outcome, liver transplantation is a poor therapeutic choice for patients with either primary or metastatic liver sarcoma, including high-grade leiomyosarcoma (GIST) regardless of primary site or primary therapy.

Incompatible kidney donor candidates' willingness to participate in donor-exchange and non-directed donation.

Although paired donation, list donation and non-directed donation allow more recipients to receive living donor transplants, policy makers do not know how willing incompatible potential donors are to participate. We surveyed 174 potential donors ruled out for ABO-incompatibility or positive cross-match about their participation willingness. They were more willing to participate in paired donation as compared to list donation where the recipient receives the next deceased donor kidney (63.8% vs. 37.9%, p < 0.001) or non-directed donation (63.8% vs. 12.1%, p < 0.001). Their list donation willingness was greater when their intended recipients moved to the top versus the top 20% of the waiting list (37.9% vs. 19.0%, p < 0.001). Multivariate logistic regression modeling revealed that potential donors' empathy, education level, relationship with their intended recipient and the length of time their intended recipient was on dialysis also affected willingness. For paired donation, close family members of their intended recipient (odds ratio (OR) = 3.01, confidence intervals (CI) = 1.29, 7.02), with high levels of empathy (OR = 2.68, CI = 1.16, 6.21) and less than a college education (OR = 2.67, CI = 1.08, 6.61) were more willing to participate compared to other donors. Extrapolating these levels of willingness nationally, a 1-11% increase in living donation rates yearly (84-711 more transplants) may be possible if donor-exchange programs were available nationwide.

Body weight alterations under early corticosteroid withdrawal and chronic corticosteroid therapy with modern immunosuppression.

UNLABELLED: Weight gain is a well-known complication of corticosteroid maintenance therapy. The purpose of our study was to compare patterns of weight gain under chronic corticosteroid therapy (CCST) to those observed under early corticosteroid withdrawal (CSWD) in renal transplant recipients. METHODS: Renal transplant recipients who underwent early CSWD in IRB-approved prospective trials were compared to a historical control group of patients receiving CCST who were matched for age, sex, and race. RESULTS: One hundred sixty-nine patients with early CSWD were compared to 132 patients who received CCST. Mean population weight gain was significantly higher in CCST patients at 12 months (5.52 kg vs 3.05 kg, P < .05) posttransplant. Caucasian CSWD patients demonstrated a greater reduction in weight gain with CSWD than African Americans (mean weight decrease 2.9 vs 1.9 kg/patient, P < .05). Patients who were overweight (body mass index [BMI] 25-30) or obese (BMI > 30) demonstrated a greater reduction in weight gain with CSWD at 1 year (mean reduction in weight gain with CSWD 5.3 kg/patient and 4.4 kg/patient) than did patients of normal weight (BMI < 25; 0.1 kg/patient, P < .01 and <.05 versus BMI < 25). CONCLUSIONS: Early CSWD patients gain significantly less weight than CCST patients following transplantation. Marked variations in the effect of early CSWD on weight gain may be observed due to race and pretransplant BMI. Caucasians and overweight patients demonstrate greater benefits from CSWD than African Americans and patients with normal BMI.

Skin cancer following transplantation: the Israel Penn International Transplant Tumor Registry experience.

UNLABELLED: The purpose of this study was to analyze a large series of skin cancers in solid organ transplant recipients to determine their biologic behavior. METHODS: A retrospective review of all US transplant recipients with skin cancer reported to the Israel Penn International Transplant Tumor Registry was performed. RESULTS: Transplant recipients from the United States with skin malignancies were identified (n = 2018) and assigned to 1 of 3 groups: squamous cell cancer (SCC), basal cell cancer (BCC), or combined malignancies (BCC/SCC). Squamous cell to basal cell cancer ratio was found to be 1.9 to 1. The ratio of extrarenal to renal allograft recipients was identical for all 3 groups (3:1). The median interval from transplant to skin cancer diagnosis was greater than 4 years in each group and longest in those with isolated SCC lesions. In the SCC group, there was a 9% incidence of nodal or secondary site involvement affecting the cervix, perineum, or lung. The highest recurrence rate was demonstrated in the combined malignancy group. Cancer-specific deaths were significantly higher in the SCC (8%) and BCC/SCC (6.8%) groups compared to the BCC (3.6%) group. CONCLUSIONS: This large experience indicates that SCC is more common than BCC in transplant recipients. SCC alone or in combination with BCC appears aggressive and is associated with significant mortality.

Early steroid withdrawal does not increase risk for recurrent focal segmental glomerulosclerosis.

UNLABELLED: Experience with early corticosteroid withdrawal (CSWD) in renal transplant recipients with focal segmental glomerulosclerosis (FSGS) has not been previously reported. Since corticosteroids are used to treat primary FSGS, concern exists as to whether early CSWD regimens will be associated with an increased risk of FSGS recurrence posttransplant. The purpose of the present study was to evaluate the results of early CSWD in FSGS recipients and compare these results to a historic control group of FSGS patients who underwent renal transplantation under corticosteroid-based immunosuppression. METHODS: Forty-three patients with FSGS underwent renal transplantation with early CSWD. Results in these patients were compared to FSGS patients that underwent renal transplantation with chronic corticosteroid therapy. All rejection episodes were biopsy proven with grading by Banff criteria. Statistical analyses included Student's t test and chi square tests. RESULTS: Results in 43 patients with a median follow-up of 569 days were analyzed and compared to control patients. There was no significant difference in recurrent FSGS, time to recurrence, or graft loss. CONCLUSION: CSWD does not increase risk for recurrence of FSGS. These observations indicate that ECSW can be achieved in FSGS patients, thereby affording them the benefits of steroid elimination.

African American renal transplant recipients benefit from early corticosteroid withdrawal under modern immunosuppression.

African Americans have historically been considered high-risk renal transplant recipients due to increased rejection rates and reduced long-term graft survival. Modern immunosuppression has reduced rejections and improved graft survival in African Americans and may allow successful corticosteroid withdrawal. Outcomes in 56 African Americans were compared to 56 non-African Americans enrolled in early withdrawal protocols. Results are reported as African American versus non-African American. Acute rejection at 1 year was 23% and 18% (P = NS), while patient and graft survival was 96% versus 98% and 91% versus 91% (P = NS), respectively. In conclusion, early withdrawal in African Americans is associated with acceptable rejection rates and excellent patient and graft survival, indicating that the risks and benefits of early withdrawal are similar between African Americans and non-African Americans. Additional followup is needed to determine long-term renal function, graft survival, and cardiovascular risk in African Americans with early steroid withdrawal.

Pilot study of early corticosteroid elimination after pancreas transplantation.

UNLABELLED: Early corticosteroid withdrawal has recently been shown to be possible in recipients of simultaneous pancreas kidney transplants; however, its feasibility in solitary pancreas recipients has not been documented. In the present study, we provide evidence that early withdrawal can be achieved in pancreas as well as pancreas-kidney recipients. METHODS: Twenty type I diabetics underwent 13 pancreas-kidney transplants and 7 pancreas-only transplants with early withdrawal (methylprednisone 6-day taper). Additional immunosuppression consisted of tacrolimus, mycophenolate mofetil, and thymoglobulin induction (five doses). RESULTS: Transplants included 13 pancreas-kidney, 6 pancreas after kidney transplant, and 1 pancreas after islet transplant. Overall mean follow-up was 7.3 months. One episode of pancreas transplant rejection after pancreas-only transplant was detected on protocol biopsy without biochemical abnormalities. One renal allograft rejection occurred 65 days posttransplant in a pancreas-kidney recipient and was graded as a Banff IA rejection. A single pancreas graft loss occurred due to thrombosis 6 days after pancreas-kidney transplantation. CONCLUSIONS: These results indicate that relatively short thymoglobulin induction (five doses) with tacrolimus and mycophenolate mofetil can allow early withdrawal in both pancreas-kidney and pancreas-only transplant recipients.

Early corticosteroid withdrawal under modern immunosuppression in renal transplantation: multivariate analysis of risk factors for acute rejection.

UNLABELLED: Early corticosteroid withdrawal has been shown to be effective in low-risk patient populations in a number of US and European multicenter trials. However, patient populations traditionally considered to be at high risk for acute rejection (eg, African Americans, repeat transplant recipients, sensitized patients) are usually excluded from these trials. Since our initial experience with early withdrawal almost 10 years ago, we have included high-immunologic-risk patients. We have accumulated enough high-risk patients with early withdrawal to allow the first multivariate analysis of risk factors for acute rejection in early withdrawal under modern immunosuppression. METHODS: Early withdrawal was performed under prospective IRB-approved protocols. Statistical analysis included chi square test and logistic regression. All rejection episodes were biopsy proven and graded by Banff 1997 criteria. RESULTS: A total of 164 patients underwent early withdrawal: 82% had at least one mismatched DR antigen, 17% had delayed graft function, 33% were African American, and 18% were repeat transplant recipients. Multivariate analysis of risk factors for acute rejection indicated that two factors induced a statistically significant alteration in acute rejection risk: repeat transplant recipients (4.3-fold increased risk) and thymoglobulin induction (0.30 risk (ie, 70% reduction in risk compared to patients not receiving thymoglobulin induction). Sensitized recipients and African Americans were also at increased risk but did not quite reach statistical significance. These data strongly support the use of T-cell depleting antibody induction therapy in high-risk patients undergoing early withdrawal under modern immunosuppression.

Corticosteroid avoidance ameliorates lymphocele formation and wound healing complications associated with sirolimus therapy.

INTRODUCTION: Sirolimus (RAPA) and corticosteroids (CS) both inhibit wound healing. To evaluate the possibility that RAPA and CS have additive effects on wound healing, we evaluated the effects of corticosteroid avoidance (CSAV) on wound healing complications in patients treated with RAPA. METHODS: One hundred nine patients treated with a CSAV regimen (no pretransplantation or posttransplantation CS) were compared with a historical control group (n = 72) that received cyclosporine (CsA), mycophenolate mofetil (MMF), and CS. The CSAV group received low-dose CsA, MMF, RAPA, and thymoglobulin induction. Complications were classified as follows: wound healing complications (WHC) or infectious wound complications (IWC). WHC included lymphocele, hernia, dehiscence, diastasis, and skin edge separation. IWC included wound abscess and empiric antibiotic therapy for wound erythema. RESULTS: The CSAV group was largely CS-free: 11% of patients received CS for rejection, 12% of patients received CS for recurrent disease, and 85% of patients are currently off CS. The CSAV group had a significantly lower incidence of WHC (13.7% vs 28%; P = .03) and lymphoceles (5.5% vs 16%; P = .02) than the control group. There was no difference in the incidence of IWC between the 2 groups. Patients who received CSAV were 18% less likely (P = .57) to develop any type of complication, 41% less likely (P = .20) to develop a WHC, and 71% less likely (P = .018) to develop a lymphocele. CONCLUSIONS: CSAV in a RAPA-based regimen results in a marked reduction in WHC and lymphoceles. Therefore, CSAV provides a promising approach for addressing WHC associated with RAPA therapy.

A prospective, randomized, multicenter, double-blind study of early corticosteroid cessation versus long-term maintenance of corticosteroid therapy with tacrolimus and mycophenolate mofetil in primary renal transplant recipients: one year report.

This report summarizes year 1 blinded data from a 5-year prospective, randomized (1:1, stratified by race and donor type), multicenter, double-blind study comparing treatment failure rates between early cessation of corticosteroid therapy and long-term corticosteroid maintenance therapy in 397 primary renal transplant recipients receiving tacrolimus and mycophenolate mofetil with antibody induction. Sixteen (4.1%) patients died or experienced graft loss during year 1 (9 deaths, 6 graft losses, and 1 death with a graft loss). Fifty-nine (15.3%) patients experienced rejection; 40 (10.4%) of these cases were biopsy-confirmed. Values for 10-year predictive risk of coronary heart disease (CHD) estimated from the Framingham Heart Study scores showed a shift from baseline toward a more favorable risk profile. Renal transplant recipients treated with a tacrolimus-based immunosuppressive regimen and either early cessation or maintenance of corticosteroid therapy experienced excellent patient and graft survival, low acute rejection rates, low rate of posttransplantation diabetes mellitus (9.0%), and improved CHD risk profile at 1 year posttransplantation.

Kidney exchange programs: attitudes of transplant team members toward living donation and kidney exchanges.

INTRODUCTION: Several living donor kidney exchange programs (LDKEPs) have been established throughout the world; however, none have yet achieved the perceived substantial potential for increasing the number of living donor kidney transplants. Over the past 2 years, the Ohio Solid Organ Transplant Consortium (OSOTC) has developed and implemented an LDKEP with a complementary, robust web-based computerized matching program for living donor/recipient pairs. Prior to implementation of the OSOTC LDKEP, attitudes of transplant professionals from each of eight participating kidney transplant programs were surveyed to determined attitudes toward living donation and LDKEP and to identify potential barriers to LDKEP. The state of decision making toward LDKEP was also examined. METHODS: Transplant professionals were surveyed using an instrument designed to assess attitudes toward living donation and LDKEPs. Most questions were answered on a Likert scale (1 = strongly agree, 5 = strongly disagree). RESULTS: Respondents agreed that living donor transplantation should be encouraged (mean 1.17 +/- 0.6) and that the laparoscopic donor procedure was preferred (1.36 +/- 0.82). Respondents had largely read about KEPs (2.02 +/- 1.02) but had "thought about participating in KEPs" (2.57 +/- 1.26), or actively sought information (2.87 +/- 1.3) to lesser degrees. Despite this, significant indecisiveness existed regarding participation in LDKEPs (2.73 +/- 1.39). CONCLUSIONS: Transplant professionals are highly aware of LDKEPs. However, they remain indecisive about LDKEP participation. These results indicate that barriers exist in the transplant community toward LDKEP, and these must be defined to increase LDKEP acceptance and participation.

Outcomes of patients with rejection post-polyomavirus nephropathy.

INTRODUCTION: We sought to determine the effects of rejection in renal transplant recipients with polyomavirus nephropathy (PVN). METHODS: SCr, biopsy findings, BKV serum and urine loads (Taqman PCR), and BKV antibody titers (HA inhibition assay) were analyzed by two-sample median tests and z tests in 11 patients with median follow-up of 7.3 (2.0 to 31.5) months post-PVN. All patients underwent immunosuppression reduction (ISR) as PVN treatment. RESULTS: Post-PVN, 3 (27%) patients had five rejection episodes, with 80% being mild. Median time to rejection was 18 (2 to 60) weeks. One hundred percent of patients who experienced post-PVN rejection also experienced rejection pre-PVN. Rejection episode treatments consisted of: none in one, increased tacrolimus in two, IVIG in one, IVIG and increased tacrolimus in one. Median viral loads in patients with post-PVN rejection versus those without rejection were not different in serum (2.01 x 10(4) vs 9.00 x 10(4) BKV copies/mL; P = .22) or urine (5.37 x 10(5) vs 8.93 x 10(6) BKV copies/mL; P = .28). Median BKV antibody titers were slightly lower (16384 vs 32768 HA units; P = .02) and median SCr values were significantly higher (2.7 vs 1.9 mg/dL, P = .0003) in patients who had experienced post-PVN rejection. Graft losses occurred in one rejection-free patient (chronic allograft nephropathy) and in one patient who experienced multiple acute rejection episodes, humoral rejection, and worsening PVN. CONCLUSIONS: Patients who experience rejection prior to PVN are at high risk of developing rejection post-ISR and post-PVN; however, low graft loss rates may still be achieved.

Donor kidneys with small renal cell cancers: can they be transplanted?

INTRODUCTION: The purpose of this study was to determine whether incidentally discovered, small renal cell cancers (RCC) in donor kidneys can be excised and safely transplanted. METHODS: The Israel Penn International Transplant Tumor Registry database was searched and all small RCC that were identified and resected prior to transplantation of deceased and living donor kidneys were reviewed. Patient demographics, tumor characteristics, recurrence, and survival were examined. RESULTS: Fourteen kidneys were identified in which small RCC were noted at the time of procurement and where the tumors were excised ex vivo and then transplanted. Eleven kidneys were obtained from living related donors and three were from deceased donors. Median tumor size was 2 cm (range 0.5 to 4 cm). All 14 tumors were of histological Furhman grade II/VI (n = 8) or Furhman grade I/VI (n = 6). All kidneys had pathologically confirmed negative margins. The mean age of the recipients was 40.8 +/- 9.2 years, with the majority being men (11 men; 3 women). Median follow-up for this group was 69 months (range 14 to 200 months). There have been no recurrences of tumor in these recipients and the 1-, 3-, and 5-year patient and graft survivals are 100%, 100%, and 93%. CONCLUSIONS: These data represent the only data available (to our knowledge) on this issue. This experience indicates that donor kidneys with small, incidental RCC and low histological grade (Furhman grade I and II/IV) can be managed with excision and transplantation, with a low risk of tumor recurrence in the recipient.

De novo colorectal cancer: five-year survival is markedly lower in transplant recipients compared with the general population.

INTRODUCTION: The biological behavior of most solid tumors in transplant recipients has not been adequately compared to the general population. The purpose of the present study was to compare outcomes in de novo colorectal cancer (CRC) following solid organ transplantation to those observed in the general population (SEER) database. METHODS: All transplant recipients with de novo CRC in the Israel Penn International Transplant Tumor Registry were identified and analyzed and the data were compared to CRC patients in the SEER National Cancer Institute (NCI) database. RESULTS: One hundred and fifty transplant recipients with de novo CRC were identified, among which were 93 (62%) kidney, 29 (19.3%) heart, 27 (18%) liver, and 1 (0.7%) lung recipients. Median age of transplant recipients was 54 years, compared to a median age of 72 years for patients in the SEER NCI database. However, compared to patients from the SEER NCI database, recipients with Duke's A through C stage disease were noted to experience a significant decrease in 5-year survival. The results in Duke's C patients were particularly dismal. CONCLUSIONS: The early age at presentation of CRC in transplant recipients suggests that the development of de novo CRC may be effected by immunosuppression. Decreased 5-year survival rates in transplant recipients compared to the general population suggest that CRC in transplant patients is biologically more aggressive. These data cannot distinguish whether the lower survival rates are because the CRC are inherently biologically more aggressive or whether immunosuppression allows for more aggressive clinical behavior of CRC.

Chemotherapy for posttransplant lymphoproliferative disorder: the Israel Penn International Transplant Tumor Registry experience.

INTRODUCTION: Very little published data exist regarding the results of chemotherapy treatment of posttransplant lymphoproliferative disorder (PTLD). The purpose of the study was to review the Israel Penn International Transplant Tumor Registry experience with PTLD treated with chemotherapy. METHODS: Patients with PTLD who received chemotherapy were identified and data collected regarding demographics, tumor characteristics, recurrence rates, and survival. RESULTS: One hundred ninety three solid organ transplant recipients with PTLD who received chemotherapy were identified. Most patients were male (142:51) and Caucasian (148; 16 AA, 29 unspecified). Most PTLD were B-cell predominant (81%), monoclonal (71), and CD 20+ (60% of patients tested). Organ transplanted included: kidney, 92 (48%); heart, 54 (28%); liver, 30 (16%); pancreas, 8 (4%); and lung, 9 (5%). Median time to presentation posttransplant was 24.5 months (range 0.8 to 226.5 months). Ninety patients received CHOP, 12 ProMACE, 65 other multidrug regimens, and 23 patients received single-agent chemotherapy. Five-year survival for these four regimens were: 24%, 25%, 32%, and 5%. PTLD-specific death rates were 34%, 34%, 40%, and 48%. CONCLUSIONS: Single-agent chemotherapy appears to be inferior to other chemotherapy regimens for PTLD as it is associated with lower survival.

Central nervous system tumors in donors: misdiagnosis carries a high morbidity and mortality.

INTRODUCTION: The cost of misdiagnosis of central nervous system (CNS) tumors in donors has not been previously described. The purpose of this study was to examine the Israel Penn International Transplant Tumor Registry experience with these donors. METHODS: All cases where an error in diagnosis was made due to intracranial hemorrhage from undiagnosed CNS tumors and where CNS metastases were misdiagnosed as primary brain tumor were examined. RESULTS: Forty-two organ recipients with misdiagnosed primary brain deaths from 29 donors were examined. After transplantation these donors were identified with: melanoma (23%), renal cell carcinoma (19%), choriocarcinoma (12%), sarcoma (10%), Kaposi's sarcoma (7%), and variable tumors (22%). The majority of patients were renal allograft recipients (84%) followed by liver (n = 4) and lung recipients (n = 1). The most commonly diagnostic error was with intracranial hemorrhage (ICH) (62%). A donor-related transmission rate of 74% (31/42) was identified among those patients with a misdiagnosed brain death. The majority of donor-transmitted cancers were identified in the recipient allograft (71%). Sixty-four percent of recipients suffered diffuse metastatic disease. Overall survival was poor, with a 5-year survival rate of 32% (10/31). Explantation was performed in 17 patients with confirmed donor-transmitted cancer, and in these patients a survival benefit was noted (10/17, 59%, vs 0/14, 0%; P < .01). CONCLUSIONS: Error in the diagnosis of donor brain death due to CNS tumors has significant and often fatal consequences. Allograft explantation for kidney recipients or retransplantation for extrarenal recipients may provide a survival benefit. Potential donors with unclear etiologies for brain death, particularly ICH, should be considered for a limited brain autopsy after donation.

Laparoscopic right living donor nephrectomy.

INTRODUCTION: Left laparoscopic donor nephrectomy (LDN) is preferred over right LDN due to technical ease. The purpose of this study was to compare results between right and left LDN and thereby determine whether substantial experience with right LDN can provide results equivalent to left LDN. METHODS: All LDN from 2000 to 2004 were reviewed, and right LDN data compared to left LDN data. Statistical analyses included chi-square and Student t tests. RESULTS: Two hundred thirteen left LDN (84%) were compared to 40 right LDN (16%). Donor age, gender, race, and body mass index, and multiple arteries were similar in right and left LDN groups. Operative and cold ischemia times were similar, but warm ischemia was longer for right LDN (3:55 +/- 1:22 minutes) than left LDN (3.18 +/- 1:06 minutes; P = .004). Despite this, renal allograft function was similar on postoperative day 7 (creatinine 1.77 +/- 1.21 for right LDN, 1.7 +/- 1.5 for left LDN) and at 1 year (right LDN 1.5 +/- 0.4, left LDN 1.23 +/- 0.28). Graft survival rate in the right LDN at 1 year was 97.5%. CONCLUSIONS: This large experience with right LDN indicates that results comparable to left LDN can be obtained. This observation increases the options for LDN in patients with multiple left renal arteries, or with right renal cysts, or with right kidneys that are smaller in size compared to the contralateral left kidney.

Prostate cancer prior to solid organ transplantation: the Israel Penn International Transplant Tumor Registry experience.

INTRODUCTION: Prostate adenocarcinoma (PCA) is the second leading cause of cancer-related deaths in men, and with routine prostrate specific antigen (PSA) screening, is being diagnosed with increasing frequency. To date, reported experiences with transplantation in men with a history of PCA are limited to only a few patients. This study presents the first series of transplant recipients with a history of PCA. METHODS: Analysis of transplant recipients with a history of pretransplant PCA was performed on the Israel Penn International Transplant Tumor Registry database. PCA were staged using American Joint Committee on Cancer criteria. Statistics analysis was performed by chi-square and Student t tests. RESULTS: Ninety patients with preexisting PCA were identified: 77 renal, 10 heart, and three liver transplant recipients. Mean age at PCA diagnosis was 61.3 +/- 6.3 years. Median interval between diagnosis and transplantation was 19.3 months, and median follow-up after transplantation was 20.5 months. Median time to PCA recurrence was 10.6 months after transplantation and median survival time with recurrent PCA was 49.2 months after transplant. Patient mortality was 28.8%, and PCA-related death rate was 7.8%. PCA recurrence rate was 17.7%. Tumor recurrence rates in stage I and II disease (14 and 16%) were lower than in stage III disease (36%). CONCLUSIONS: In conclusion, death rate to disease other than PCA is three times that due to PCA. PCA recurrence rates are relatively low in patients who initially presented with stage I and II disease, and are half that of patients with stage III disease.
