ABSTRACT

PURPOSE: Our study aimed to compare the surgical outcomes of robot-assisted partial nephrectomy (RAPN) between younger and older patients after adjusting for their background differences. We particularly assessed RAPN outcomes and safety in older patients. METHODS: We retrospectively evaluated 559 patients clinically diagnosed with T1 renal cell carcinoma (RCC) and treated with RAPN between 2013 and 2022 at five institutions in Japan. The patients were classified into two groups according to their age during surgery (younger group: < 75 years, older group: ≥ 75 years). Propensity score matching (PSM) was performed to adjust for the differences in the backgrounds between younger and older patients, and surgical outcomes were compared. RESULTS: Among the 559 patients, 422 (75.5%) and 137 (24.5%) were classified into the younger and older groups, respectively; 204 and 102 patients from the younger and older groups were matched according to PSM, respectively. Subsequently, patient characteristics other than age were not significantly different between the two groups. In the matched cohort, the older group had more patients with major complications (younger, 3.0%; older, 8.8%; P = 0.045). CONCLUSION: Surgical outcomes of RAPN in older patients with RCC were comparable with those in younger patients, although older patients experiencedsignificantly more complications than younger patients. These results suggest the need for further detailed preoperative evaluation and appropriate postoperative management in older patients receiving RAPN.

ABSTRACT

Introduction: Renal collecting duct carcinoma is often found in advanced cancers and has a poor prognosis. Here, we present the case of symptomatic metastatic collecting duct carcinoma in which we observed an initial therapeutic effect of immune checkpoint inhibitors plus tyrosine kinase inhibitors. Case presentation: The patient was a 69-year-old male who was referred to our hospital for examination of a right chest tumor and related pain. Contrast-enhanced computed tomography and tumor biopsy were performed, leading to a diagnosis of collecting duct carcinoma. A combination of pembrolizumab plus axitinib was initiated as first-line therapy; right chest pain decreased, and tumor shrinkage was observed. Seven months after treatment initiation, tumor progression was noted. Cabozantinib was initiated as second-line therapy; however, was discontinued due to patient fatigue. The patient died 15 months after the initiation of treatment. Conclusion: For symptomatic metastatic collecting duct carcinoma, pembrolizumab plus axitinib may have initial therapeutic effects.

ABSTRACT

Chronic unilateral hematuria due to hemangioma of the renal papilla is endoscopically treatable. Hemangiomas of the renal papilla are usually located at the tip of the renal papilla. However in this case, the hemangioma was not located at the tip of the renal papilla, forcing the patient to exercise until just before surgery and to keep the renal pelvic pressure low to identify the hemangioma.

ABSTRACT

The patient is a 47-year-old female. MRI revealed a well-defined submuscular mass in the bladder muscle layer. Bladder paraganglioma was suspected based on MRI findings. Endocrinologic Testing showed no significant elevation. 123I-MIBG scintigraphy of the mass showed a significant uptake, and we made diagnosis of bladder paraganglioma. The mass was nonrising and showed no color differentiation making its location undetectable. Using MRI with a ureteral stent and urethral catheter in place, we were able to determine its location. The possibility of damage to the ureteral or internal urethral opening was feared. We chose open bladder surgery, emphasizing ease of operation and visualization. Although a transient increase in blood pressure was observed during the operation, the mass was resected as a single mass from all layers of the bladder without damaging the ureteral or internal urethral opening. Histopathological examination revealed a paraganglioma.MRI (ureteral stent and urethral catheter placement) and open bladder surgery were useful for identifying the location and resecting this case of this otherwise undetectable bladder paraganglioma.

ABSTRACT

We performed laparoscopic live donor nephrectomy (LDN) on approximately 200 patients in Ehime Prefectural Center Hospital between 2003 and 2016. In 2016, a fifty-something woman who was a donor candidate for her husband was revealed to have a horseshoe kidney through contrast-enhanced computed tomography; other LDN procedures used a retroperitoneal approach, but this one used a transperitoneal approach since the latter approach allowed for a more favorable visual field. The left kidney was selected since renal scintigraphy showed equal bilateral renal function and renal arteries are simpler on the left side. The kidney was removed after the isthmus was successfully transected without ischemia. The opened calyx in the left kidney was sutured via bench surgery, and the kidney was transplanted to the recipient. Postoperative courses of both donor and recipient were good.

ABSTRACT

PURPOSE: To evaluate the health-related quality of life (HRQoL) of Japanese men on active surveillance (AS) in the Prostate cancer Research International Active Surveillance study in Japan (PRIAS-JAPAN). METHODS: Participants were included in the PRIAS-JAPAN HRQoL study between January 2010 and March 2016. Their general HRQoL was assessed using a validated Japanese version of the Short-Form 8 Health Survey (SF-8) at enrolment and annually thereafter until discontinuation of AS. The SF-8 mental component summary (MCS) and physical component summary (PCS) of men on AS were compared with scores of the general population (norm-based score [NBS]: 50) and MCS and PCS scores for men following AS were analysed over time. We tested whether MCS and PCS scores over time explained discontinuation of AS. RESULTS: Five hundred and twenty-five patients enrolled, and the median age at baseline was 68 years. At enrolment and after 1-, 2-, and 3-year follow-ups, the PCS and MCS scores were significantly higher than the NBS of the general Japanese population except for the median PCS at 3 years. We found that age at diagnosis and time on AS negatively affected the PCS score of men on AS, while every additional year on AS led to a 0.27 point increase in MCS scores. Neither PCS nor MCS were predictors for discontinuation of AS. CONCLUSION: Japanese men following an AS strategy for 3 years reported better HRQoL compared with the general population, indicating that monitoring Japanese low-risk prostate cancer patients can be an effective treatment strategy.

ABSTRACT

BACKGROUND: There have been few reports on health-related quality of life (HRQOL) after laparoscopic radical prostatectomy (LRP) in Japanese patients. The aim of this study is to assess changes in HRQOL during 36 months after LRP compared with retropubic radical prostatectomy (RRP). METHODS: The subjects were 105 consecutive patients treated with LRP between 2011 and 2012. HRQOL was evaluated using the International Prostate Symptom Score (IPSS), Medical Outcome Study 8-Items Short Form Health Survey (SF-8), and Expanded Prostate Cancer Index Composite (EPIC) at baseline and 1, 3, 6, 12 and 36 months after surgery. These results were compared with data for 107 consecutive patients treated with RRP between 2005 and 2007. The comparison between LRP and RRP was examined at every time point by Mann-Whitney U-test and chi-square test. Multiple linear regression analysis was used to identify independent factors related to the urinary domain in EPIC. RESULTS: The IPSS change was similar in both groups. The LRP group had a better SF-8 mental component summary score at baseline and a better SF-8 physical component summary score at 1 month after surgery. In EPIC, urinary function and bother were worse after LRP, but improved at 12 months and did not differ significantly from those after RRP; however, these factors then worsened again at 36 months after LRP. Urinary incontinence was also worse at 36 months after LRP, compared to RRP. In patients treated with nerve-sparing surgery, urinary function and urinary incontinence were similar and good at 12 and 36 months in both groups. Bowel function and bother, and sexual function and bother were similar in both groups and showed no changes from 12 to 36 months. Age and salvage radiotherapy were independent predictors of incontinence (daily use of two or more pads) in multivariate analysis. Surgical procedure was not an independent factor for incontinence, but incontinence defined as use of one pad or more was associated with the surgical procedure. CONCLUSIONS: Urinary function and bother at 36 months were worse after LRP than after RRP. Age, salvage radiotherapy and surgical procedure were associated with urinary incontinence after 36 months.

ABSTRACT

BACKGROUND: The aim of this study was to examine the histological outcome and potential therapeutic benefit of second transurethral resection (TUR) for high-grade T1 bladder cancer. PATIENTS AND METHODS: The subjects were 171 patients who underwent initial TUR between January 1993 and December 2013, and were diagnosed with high-grade T1 bladder cancer. Second TUR was performed within 4-6 weeks after the initial resection. Intravesical recurrence, invasive intravesical recurrence, and disease-free, progression-free, and overall survival were examined between second TUR group and no second TUR group. RESULTS: Of the 171 patients, 79 (46.2%) underwent second TUR. Histological findings from second TUR were no cancer in 33 (41.8%), carcinoma in situ in 18 (22.9%), Ta in 15 (19.0%), T1 in 12 (15.2%), and muscle invasive bladder cancer (T2) in 1 case (1.3%). The 5- and 10-year intravesical recurrence-free survival rates were 72.0% and 57.4%, respectively, and the disease-free survival rates at these times were 69.7% and 49.6%, respectively. Second TUR had no influence on intravesical recurrence, regardless of the use of Bacillus Calmette-Guerin (BCG) therapy. No BCG therapy and recurrent cancer were significantly associated with intravesical recurrence in multivariate analysis. Recurrent cancer was also a significant risk factor for invasive intravesical recurrence. BCG therapy significantly improved disease-free survival. Second TUR was a significant factor in overall survival. In the histological results for second TUR, no cancer and Tis cases had reduced intravesical recurrence compared to Ta and T1 cases. CONCLUSION: Second TUR allows more accurate staging and pT0 cases in second TUR have a better outcome, indicating a possible therapeutic benefit of the procedure.

ABSTRACT

INTRODUCTION: Usefulness of complete metastasectomy against pulmonary metastases from renal cell carcinoma (RCC) is well known. We examined the efficacy of surgical resection of pulmonary metastases from RCC performed in Shikoku Cancer Center. METHOD: Between January 2004 and December 2014, 11 patients with pulmonary metastases from RCC underwent thoracic resection in our institution. We examined disease-free interval (DFI) and overall survival of these patients after pulmonary metastasectomy. RESULTS: Patients included 9 men and 2 women with a mean age of 63.2 years. The median number of metastases was 1 (range 1-6). Overall, 5 patients had a single metastasis (45.5%), 8 patients had unilateral metastases (72.7%), and 3 patients received immunotherapy or chemotherapy in the interval between radical nephrectomy and pulmonary metastasectomy. We performed complete pulmonary metastasectomy in these patients. The median observation period was 43 months (range 5-82), median DFI was 5 months (range 2-17), and 3-year overall survival rate was 86%. In the 3 patients who had primary or metastatic tumors with sarcomatoid (SA) component, their median DFI tended to be shorter than that of 8 patients without it (2 vs. 8 months, p = 0.07). CONCLUSION: The pulmonary metastasectomy for RCC is a treatment option, while the indication for RCC with SA component should be carefully considered.

ABSTRACT

PURPOSE: To define clinical and pathological factors predicting reclassification at the time of 1-year repeat biopsy (re-Bx) based on a Japanese cohort forming part of the Prostate Research International: Active Surveillance (PRIAS) study. PATIENTS AND METHODS: The inclusion criteria for the PRIAS study are as follows: clinical stage T1c/T2, PSA ≤ 10 ng/ml, PSA density (PSAD) < 0.2 ng/ml per milliliter, one or two positive biopsy cores, and Gleason score (GS) ≤ 6 at initial diagnostic biopsy. Baseline clinical characteristics and prostate-specific antigen doubling time (PSADT) at the time of re-Bx were analyzed via multivariate logistic regression with respect to reclassification and 'no cancer' status on the 1-year re-Bx. RESULTS: A total of 386 patients were enrolled in PRIAS-JAPAN by the end of 2013. Of these, 216 underwent re-Bx at 1 year. A total of 73 patients (33.8 %) were reclassified, whereas 74 (34.3 %) had no cancer. Older age, a higher PSAD, a higher positive core rate, and a shorter PSADT were significant predictors of reclassification. The positive core rate was the predictor common to reclassification, no cancer, and high GS, upon re-Bx. CONCLUSIONS: An interim analysis of a Japanese AS cohort participating in PRIAS revealed that the positive core rate was strongly associated with reclassification at the 1-year re-Bx. However, although amendment of the PRIAS inclusion criteria to incorporate a positive core might reduce any concern about underestimation, this would also reduce the number of patients undergoing AS.

ABSTRACT

OBJECTIVE: To assess health-related quality of life in the first year after laparoscopic radical prostatectomy compared with that after open radical prostatectomy. METHODS: The subjects were 105 consecutive patients with localized prostate cancer treated with laparoscopic radical prostatectomy between January 2011 and June 2012. Health-related quality of life was evaluated using the International Prostate Symptom Score, Medical Outcome Study 8-Items Short Form Health Survey (SF-8) and Expanded Prostate Cancer Index Composite at baseline and 1, 3, 6 and 12 months after surgery. Comparisons were made with data for 107 consecutive patients treated with open radical prostatectomy between October 2005 and July 2007. RESULTS: The International Prostate Symptom Score change was similar in each group. The laparoscopic radical prostatectomy group had a better baseline Medical Outcome Study 8-Items Short Form Health Survey mental component summary score and a better Medical Outcome Study 8-Items Short Form Health Survey physical component summary score at 1 month after surgery. In Expanded Prostate Cancer Index Composite, obstructive/irritative symptoms did not differ between the groups, but urinary incontinence was worse until 12 months after surgery and particularly severe after 1 month in the laparoscopic radical prostatectomy group. The rate of severe urinary incontinence was much higher in the laparoscopic radical prostatectomy group in the early period. Urinary bother was worse in the laparoscopic radical prostatectomy group at 1 and 3 months, but did not differ between the groups thereafter. Urinary function and bother were good after nerve sparing procedures and did not differ between the groups. Bowel and sexual function and bother were similar in the two groups. CONCLUSION: Urinary function in the first year after laparoscopic radical prostatectomy is worse than that after open radical prostatectomy.

ABSTRACT

BACKGROUND: The goals of the study were to examine surveillance biopsy and active treatment in patients under active surveillance (AS) for low-risk prostate cancer and to determine the active treatment-free survival rate. METHODS: The subjects were 87 patients with low-risk prostate cancer who were under AS between 2000 and 2010. The eligibility criteria for AS were T1c, Gleason score ≤ 6, prostate-specific antigen level ≤ 10 ng/ml, one or two positive biopsies, maximum cancer involvement ≤ 50 %, and age ≤ 80 years old. RESULTS: Of the 87 patients, 48 underwent the first surveillance biopsy (55.2 %). In this biopsy, no cancer was found in 33.3 % of cases, 27.1 % remained eligible for AS, and 39.6 % did not meet the AS criteria (up-grade 22.9 %, up-volume 16.7 %). A second surveillance-biopsy was performed at 1.9 years after the first biopsy. No cancer was found in 20.0 % of cases, 40.0 % remained eligible for AS, and 40.0 % did not meet the AS criteria (up-grade 26.7 %, up-volume 13.3 %). A total of 50 patients received treatment by 1.7 years after starting AS, mainly due to an up-grade or up-volume. However, some patients underwent radiotherapy despite biopsy results indicating no cancer or eligibility for AS. The active treatment-free survival rate was 64.1 % after 2 years. CONCLUSIONS: Surveillance biopsy is important for identifying patients who require active treatment. The results in this study allowed determination of the active treatment-free survival rate and are informative for making treatment decisions.

ABSTRACT

OBJECTIVES: To examine the association between cancer location, resection margins and oncological outcome in patients undergoing radical prostatectomy. METHODS: A total of 505 patients who underwent radical prostatectomy between 1993 and 2009 were included in this analysis. Cancer location, resection margins and pathological factors were assessed based on the 2010 General Rules for Clinical and Pathological Studies on Prostate Cancer. Biochemical recurrence was defined as prostate-specific antigen >0.2 ng/mL. RESULTS: Positive resection margins were found in 38.4% of all cases, in 30.3% of pT2 cases and in 57.7% of pT3 cases. The cancer was distributed evenly among the apex-anterior, apex-posterior and middle lesions, which each accounted for approximately 30% of the whole lesion in the main tumor. A higher rate of positive resection margins (47.6%) was found in the apex-anterior lesions. In minor tumors, most cancer was located in the middle lesion and accounted for approximately 60% of the lesion. However, positive resection margins were detected significantly more frequently in the apex-anterior lesion of minor tumors. The 5-year and 10-year biochemical recurrence-free survival rates were 36.2% and 32.0%, respectively, in patients with a positive resection margin, and 82.7% and 77.4%, respectively, in those with a negative resection margin. Cancer location was an independent risk factor for biochemical recurrence and a positive resection margin. Recurrence-free survival was lower in pT2 cases with a positive resection margin compared with pT3 cases with a negative resection margin. CONCLUSIONS: Cancer location and occurrence of positive resection margins can have negative effects on recurrence-free survival. Thus, it is of utmost importance to avoid positive resection margins during radical prostatectomy.

ABSTRACT

OBJECTIVES: To examine quality of life (QOL) for 3 years after radical retropubic prostatectomy (RRP) or permanent prostate brachytherapy (PPB) and to determine differences between the two procedures. METHODS: In all 107 patients who underwent RRP and 91 who received PPB between October 2005 and July 2007 were included in this study. QOL surveys were performed using the international prostate symptom score (IPSS), the Medical Outcome Study 8-items short form health survey and the expanded prostate cancer index composite at baseline and 1, 3, 6, 12 and 36 months after treatment. RESULTS: At 3 years, all parameters for general QOL and almost all for disease-specific QOL were similar to those at 12 months. Urinary continence after RRP slightly improved from 12 months to 3 years, but it was still significantly worse than that after PPB. Scores for urinary irritation or obstruction and for bowel function and bother at 3 years were similar between the two groups. Sexual function and bother did not change between 12 months and 3 years in either group. Sexual function at 3 years after RRP was worse than that after PPB. Recovery from urinary incontinence and sexual function after RRP with nerve sparing were similar to those after PPB. Urinary incontinence at 3 years correlated with the treatment method and patients' age, whereas urinary irritation/obstruction and urinary bother correlated with the pre-treatment IPSS. CONCLUSION: QOL assessment represents an important issue in prostate cancer management. Our findings are likely to be of aid in the development of a treatment plan for prostate cancer patients.

ABSTRACT

OBJECTIVES: This study examined the rate of Gleason pattern 5 and the influence of tertiary Gleason pattern 5 on oncological outcomes. METHODS: Four hundred sixty-six patients underwent a radical prostatectomy between 1993 and 2008. Each surgical specimen was reviewed and assessed for the tumor diameter, Gleason score (which was based on the 2005 International Society of Urological Pathology Consensus Conference criteria) and the percentage of Gleason pattern 5. RESULTS: The median patient age was 68.0 years old and the median prostate-specific antigen level was 9.28 ng/ml. A tertiary Gleason pattern 5 was present in 24.2% of patients with a Gleason score of <9; in 12.2% of patients with a Gleason score of 3 + 4 and in 45.9% of patients with a Gleason score of 4 + 3. A multivariate analysis showed that a tertiary Gleason pattern 5 was not independently associated with biochemical recurrence-free survival among patients in the Gleason score of 7 and 8 pN0 groups. One hundred eighty-seven patients had any rate of Gleason pattern 5 and significantly worse pathological factors, compared with patients who did not have this pattern. A multivariate analysis of all patients showed that the surgical margin, Gleason score, prostate-specific antigen level and pathological stage were all independent predictors of biochemical recurrence. However, the rate of Gleason pattern 5 was not an independent factor. CONCLUSIONS: Tertiary Gleason pattern 5 was not a significant predictive factor for biochemical recurrence. The rate of Gleason pattern 5 was associated with adverse pathological factors.

ABSTRACT

Multiple liver metastatic lesions were shown by computed tomography and scintigraphy with 123I- metaiodobenzylguanidine (MIBG) in a 76-year-old woman 2 years after resection of a pheochromocytoma of the right adrenal gland. Transcatheter arterial chemo-embolization (TACE) was performed for the liver metastasis, with blood pressure strictly controlled by administration of doxazosin and phentolamine for the prevention of hypertensive crisis after TACE. There were no severe adverse events associated with the treatment, and the number and size of the lesions were decreased. TACE with strict blood pressure control was an effective and safe therapy for multiple liver metastatic lesions related to malignant pheochromocytoma.
