RESUMO
Background: The subtype of urothelial carcinoma (SUC) has been known to possess morphological diversity for histologic subtype or divergent differentiation. However, the efficacy of avelumab against SUC remains unclear. Therefore, the effect of the treatment as well as the survival results of avelumab monotherapy were evaluated as a first-line therapeutic maintenance in patients with advanced SUC. Methods: A retrospective analysis was conducted on consecutive patients from the Uro-Oncology Group in Kyushu study population with advanced lower and upper urinary tract cancer who underwent avelumab maintenance therapy without progression after first-line platinum-based chemotherapy. Patients with pure urothelial carcinoma (PUC) and SUC were comparatively analyzed based on objective response rate (ORR), disease control rate, progression-free survival (PFS), and overall survival (OS). Results: Out of 49 recorded patients, 38 and 11 had PUC and SUC, respectively. The most common subtype element was glandular differentiation (n=5), followed by squamous differentiation (n=3), micropapillary (n=1), and plasmacytoid subtypes (n=1). The SUC and PUC groups had comparable ORR (0% vs. 2.6%, P>0.99) and disease control rates (54.5% vs. 44.7%, P=0.73). These patient groups also showed no significant difference in PFS (median 3.9 vs. 3.1 months, P=0.33) or OS (median 16.7 vs. 22.1 months, P=0.47). Conclusions: The response of SUC and PUC to avelumab was comparable in patients with advanced lower and upper urinary tract cancer, indicating that avelumab maintenance therapy is also effective for SUC.
RESUMO
BACKGROUND/AIM: The efficacy, safety, and liver toxicity of enfortumab vedotin (EV) for elderly advanced urothelial carcinoma (UC) patients and patients with a poor performance status (PS) are unclear. PATIENTS AND METHODS: We retrospectively analyzed the efficacy, safety, and liver toxicity of EV in elderly patients and patients with a poor PS between December 2021 and August 2023. RESULTS: Sixty-two patients (≥75 years old, n=22; PS≥2, n=10) were enrolled. Patients with PS≥2 had significantly lower albumin levels than those with PS<2 (p=0.023). The objective response and disease control rates did not differ significantly between patients <75 and ≥75 years old (p=0.598 and p=0.769, respectively) or between those with PS<2 and PS≥2 (p>0.99 and p=0.178, respectively). Progression-free survival (PFS) and overall survival (OS) were not significantly different in patients <75 years and ≥75 years (p=0984, 0.368). A significant difference in PFS (p=0.047) but not OS (p=0.086) was observed between the PS<2 and PS≥2 groups. The rates of any-grade and severe (grade ≥3) adverse events did not differ significantly between patients <75 and ≥75 years (p=0.471, p=0.136) or between PS<2 and PS≥2 groups (p>0.99, 0.99). Aspartate aminotransferase (AST) levels significantly increased, but alanine aminotransferase levels did not, following EV treatment (p<0.001). Multivariate analyses revealed that the albumin level was an independent prognostic factor (hazard ratio=0.159; p<0.001). CONCLUSION: EV demonstrated similar efficacy and safety in elderly and younger patients with advanced UC. In patients with a poor PS, although the safety was similar, survival was significantly worse in terms of PFS, while the AST levels were significantly elevated.

BACKGROUND/AIM: This study retrospectively evaluated whether enfortumab vedotin (EV) monotherapy is effective as a late-line treatment according to prior treatment type in patients with advanced urothelial carcinoma (UC). PATIENTS AND METHODS: We assessed consecutive patients from the Uro-Oncology Group in the Kyushu study population with lower and upper urinary tract cancer treated with EV monotherapy after platinum-based chemotherapy and immune checkpoint inhibitor therapy failure between December 2021 and March 2024. In particular, patients receiving avelumab maintenance or pembrolizumab therapy before EV for advanced UC were analyzed and compared according to the response rate, progression-free survival (PFS), and overall survival (OS). RESULTS: Of the 80 enrolled patients, 31 and 49 received avelumab and pembrolizumab before EV therapy, respectively. The avelumab and pembrolizumab groups had comparable objective response rates (48.4% vs. 44.9%, p=0.820) and disease control rates (77.4% vs. 67.3%, p=0.448). These two groups showed no significant difference in PFS from the initiation of EV (median: 6.4 months vs. 4.2 months, p=0.184); meanwhile, the avelumab group had better OS from the initiation of EV than the pembrolizumab group (median: 16.0 months vs. 10.2 months, p=0.019). Moreover, the median OS after first-line chemotherapy initiation was longer in the avelumab group than in the pembrolizumab group (40.3 months vs. 24.7 months, p=0.054). On multivariate analysis, avelumab maintenance therapy before EV reduced the mortality risk by 47% (95% confidence interval=0.27-1.03; p=0.059). CONCLUSION: EV monotherapy after avelumab maintenance therapy provides favorable survival outcomes in patients with advanced UC.

INTRODUCTION: To evaluate the organ-specific therapeutic effect of enfortumab vedotin (EV) after chemotherapy and immunotherapy failed for advanced urothelial carcinoma. MATERIALS METHODS: At 6 institutions between December 2021 and July 2023, we retrospectively analyzed patients with metastatic upper and lower urinary tract cancer who received EV monotherapy after platinum-based chemotherapy and immune checkpoint blockade therapy. Objective response rate (ORR) and organ-specific response rate (OSRR) were evaluated according to the Response Evaluation Criteria in Solid Tumors, version 1.1. RESULTS: This study analyzed 58 patients with 210 tumor lesions, of which 24% were females and 48% had upper urinary tract cancer. The ORR and disease control rate were 53.5% and 74.1%. Moreover, we found 15 target lesions in the primary site, 7 in local recurrence, 93 in the lymph nodes, 46 in the lung, 29 in the liver, and 20 in the bone, with OSRRs of 40%, 71.4%, 61.1%, 70.6%, 90.9%, and 18.2%, respectively. Over time from baseline, the reduction rate (median) in tumor burden was 50% or more in the lymph node, lung, and liver metastases. CONCLUSION: The organ-specific tumor response to EV in patients with metastatic urothelial carcinoma was almost favorable. The antitumor activity of EV monotherapy may be less in bone metastasis than in other organ sites. Conversely, EV showed remarkably high efficacy against liver metastasis.
RESUMO
BACKGROUND/AIM: The clinical outcomes associated with cutaneous toxicity and changes in the renal function of patients receiving enfortumab vedotin (EV) for advanced urothelial carcinoma (UC) is unclear. PATIENTS AND METHODS: We retrospectively analyzed the relationship between clinical outcomes and EV-related cutaneous toxicity, and the influence on the renal function in 58 patients with advanced UC who received EV after the failure of platinum-based chemotherapy and immune checkpoint inhibitors from December 2021 to July 2023. RESULTS: There were no differences in the overall response and disease control rates between patients with any grade of EV-related cutaneous toxicity and without (p=0.605 and p>0.99, respectively) nor of grade ≥3 (p>0.99 and p=0.173, respectively). Progression-free survival was not significantly associated with EV-related cutaneous toxicity of any grade (5.4 vs. 5.6 months, p=0.557) nor of grade ≥3 (2.7 vs. 5.6 months, p=0.053). Overall survival was not significantly associated with EV-related cutaneous toxicity of any grade (11.8 vs. 8.9 months, p=0.389), nor of grade ≥3 (4.6 vs. 11.4 months, p=0.168). The incidence of EV-related cutaneous toxicity of any grade was significantly higher in patients with any grade of ICI-related cutaneous toxicity (88.9% vs. 36.7%, p=0.008). There was no significant difference in the serum creatinine levels after EV treatment (p=0.211). Divided into two groups according to their renal function, using a serum creatinine cut-off of 2 mg/dl, there were no significant changes after EV treatment in either group (p=0.187 and p=0.938). CONCLUSION: EV-related cutaneous toxicity did not affect clinical outcomes, although it occurred in patients who experienced immune checkpoint inhibitor-related cutaneous toxicity. EV did not affect renal function.

OBJECTIVES: The JAVELIN Bladder 100 phase 3 trial showed that avelumab first-line maintenance + best supportive care significantly prolonged overall survival and progression-free survival versus best supportive care alone in patients with advanced urothelial carcinoma who were progression-free following first-line platinum-based chemotherapy. We report findings from J-AVENUE (NCT05431777), a real-world study of avelumab first-line maintenance therapy in Japan. METHODS: Medical charts of patients with advanced urothelial carcinoma without disease progression following first-line platinum-based chemotherapy, who received avelumab maintenance between February and November 2021, were reviewed. Patients were followed until June 2022. The primary endpoint was patient characteristics; secondary endpoints included time to treatment failure and progression-free survival. RESULTS: In 79 patients analyzed, median age was 72 years (range, 44-86). Primary tumor site was upper tract in 45.6% and bladder in 54.4%. The most common first-line chemotherapy regimen was cisplatin + gemcitabine (63.3%). Median number of chemotherapy cycles received was four. Best response to chemotherapy was complete response in 10.1%, partial response in 58.2%, and stable disease in 31.6%. Median treatment-free interval before avelumab was 4.9 weeks. With avelumab first-line maintenance therapy, the disease control rate was 58.2%, median time to treatment failure was 4.6 months (95% CI, 3.3-6.4), and median progression-free survival was 6.1 months (95% CI, 3.6-9.7). CONCLUSIONS: Findings from J-AVENUE show the effectiveness of avelumab first-line maintenance in patients with advanced urothelial carcinoma in Japan in clinical practice, with similar progression-free survival to JAVELIN Bladder 100 and previous real-world studies, supporting its use as a standard of care.

BACKGROUND/AIM: The association between clinical outcomes and posttreatment changes in the neutrophil-to-lymphocyte ratio (NLR) and neutrophil-to-eosinophil ratio (NER) in patients receiving avelumab maintenance therapy for advanced urothelial carcinoma (UC) is unclear. PATIENTS AND METHODS: We retrospectively analyzed data from advanced UC patients who received avelumab and had not progressed with first-line platinum-based chemotherapy. The association between the changes in NLR and NER from pretreatment to week 6 of avelumab treatment and therapeutic efficacy was evaluated. RESULTS: Thirty-two patients were enrolled in this study (male, n=25; female, n=7; median age, 71 years). At six weeks, 19 patients (59.4%) had a decreased NLR and 18 patients (56.3%) had a decreased NER. When the change in NER from pretreatment to six weeks was compared, there was a significant decrease in responders (without progressive disease) (p=0.008); however, there was no significant decrease in non-responders (progressive disease) (p=0.855). The NLR showed no significant change in either group (p=0.099, 0.358). When patients were compared according to the change in the NLR at six weeks, progression-free survival (PFS) and overall survival (OS) did not differ between the decreased NLR and increased NLR groups (p=0.116, 0.256). When patients were compared according to the change in the NER, the decreased and increased groups showed significant differences in PFS and OS (p<0.001, 0.030). CONCLUSION: In the present real-world study, the responders showed a significantly decreased NER at six weeks. This was associated with improved PFS and OS in patients with advanced UC.

Subtype of urothelial carcinoma (SUC), defined here as urothelial carcinoma with any histologic subtype or divergent differentiation, is a clinically aggressive disease. However, the efficacy of enfortumab vedotin (EV) against SUC remains unclear. Hence, this study aimed to assess the oncological outcomes of patients with SUC treated with EV for metastatic disease. We retrospectively evaluated consecutive patients with advanced lower and upper urinary tract cancer who received EV after platinum-based chemotherapy and immune checkpoint blockade therapy at six institutions. The objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were compared between patients with pure urothelial carcinoma (PUC) and those with SUC. We identified 44 and 18 patients with PUC and SUC, respectively. Squamous differentiation was the most common subtype element, followed by glandular differentiation and sarcomatoid subtype. Although patients with SUC had a comparable ORR to those with PUC, the duration of response for SUC was short. Patients with SUC had poorer PFS than those with PUC; however, no significant difference was observed in OS. Multivariate analysis revealed that SUC was significantly associated with shorter PFS. Although the response of metastatic SUC to EV was similar to that of PUC, SUC showed faster progression than PUC.

Aim: We aimed to determine Japanese metastatic castration resistant prostate cancer (CRPC) patients' Ra-223 treatment experience. Patients & methods: Patients answered the Cancer Therapy Satisfaction Questionnaire (CTSQ domains: Satisfaction with Therapy [SWT], Expectations of Therapy [ET], Feelings about Side Effects [FSE]), the Memorial Anxiety Scale for Prostate Cancer (MAX-PC) and the FACT-Bone Pain (FACT-BP) Questionnaire at baseline, during (vists 3 and 5) and after treatment (end of observation; EOO). Results: Data from 72 patients were included. Baseline median CTSQ scores SWT: 66.1 (IQR19.7), ET: 75.0 (IQR45), and FSE 68.8 (IQR 34.4) were unchanged during vists 3 and 5, but the SWT (-3.57 [IQR17.9]) and ET (-5.0 [IQR30]) decreased while FSE was unchanged (0.0 [IQR31.25]) at EOO. The median MAX-PC (18.0 [IQR 49]) score was unchanged (0.0, IQR 6) while the median FACT BP (54.0 [IQR13]) score decreased by -1.0 (IQR 8) at EOO. Conclusion: Japanese metastatic castration resistant prostate cancer patients' experience is stable during Ra-223 treatment.
What is this study about? We wanted to know the treatment experience with Radium-223 (Ra-223) among Japanese prostate cancer patients. Ra-223 is a radioactive molecule used for the treatment of metastatic castration resistant prostate cancer. We asked patients to answer different questionnaires on treatment satisfaction, anxiety and quality of life before, during, and after treatment with Ra-223. What were the results? Based on the patients' answers to our questionnaires, treatment satisfaction, anxiety and quality of life remain stable while the patients undergo treatment with Ra-223, but in some aspects may decline after treatment. What do the results mean? The results mean that patients' experience during Ra-223 treatment is stable but patients should share any concerns they have about their treatment with their doctors.

BACKGROUND/AIM: The organ-specific therapeutic effects of avelumab for the maintenance treatment of advanced urothelial carcinoma (UC) are unclear. PATIENTS AND METHODS: Patients who received avelumab for advanced UC that had not progressed with first-line platinum-based chemotherapy and who had measurable disease were retrospectively analyzed. The organ-specific response was evaluated, and progression-free survival (PFS) and overall survival (OS) were estimated. RESULTS: We analyzed 42 patients (male, n=31; median age, 72 years). The overall response rate [complete response (CR)+ partial response (PR)] and disease control rate (CR+PR+stable disease) were 2.4% and 47.6%, respectively. In total, 27, 11, 8 and 5 patients had measurable lymph node [organ-specific response rate (OSRR) 7.4%, organ-specific disease control rate (OSDCR) 59.3%], lung (OSRR 18.2%, OSDCR 36.4%), primary tumor organ (OSRR 0%, OSDCR 100%) and liver (OSRR 0%, OSDCR 100%) disease, respectively. The median PFS and OS was 3.8 months and 20.2 months, respectively. Regarding organ-specific PFS, a log-rank test confirmed significant differences between patients with and without primary tumor organ disease (p=0.009) and patients with and without liver metastasis (p=0.015). Regarding organ-specific OS, a log-rank test revealed no significant differences between patients with and without metastatic disease for all organs (lung: p=0.835; lymph node: p=0.914; bone: p=0.257; primary tumor: p=0.057; liver: p=0.893). CONCLUSION: In patients receiving avelumab maintenance therapy, no significant differences in OS were observed between patients with and without metastasis to any organ, including the primary organ, although metastases and the primary tumor organ disease showed different responses.

Introduction: Dedifferentiated liposarcoma (DDLP) was initially defined as a tumor containing differentiated liposarcoma and distinct regions of nonlipogenic spindle cell or pleomorphic sarcoma. Retroperitoneal liposarcomas feature a characteristic appearance with a predominantly fatty component, and cystic liposarcomas are rare. We describe a case of retroperitoneal DDLP predominantly consisting of multilocular cysts. Case Presentation: A 77-year-old man previously visited a doctor because an echo scan unexpectedly revealed an abdominal tumor. Contrast computed tomography (CT) disclosed a large multilocular cystic tumor spanning from the left upper abdomen to the retroperitoneum, and poorly marginated soft tissue structures were present around the abdominal aorta, inferior vena cava, pancreas, mesentery, and left kidney. CT also revealed a right lung mass. The soft tissue structures in the retroperitoneal cystic tumor and right lung mass were strongly enhanced on 2-deoxy-2-[fluorine-18] fluoro-d-glucose positron emission tomography, suggesting a malignant retroperitoneal tumor and lung metastasis. CT-guided percutaneous biopsy targeting the left perirenal soft tissue structure was performed, and the tumor was diagnosed as DDLP. Lung metastasis was present, and the retroperitoneal tumor surrounded multiple organs. Therefore, the tumor was not suitable for surgical resection but it was indicated for chemotherapy based on multidisciplinary discussion. Conclusion: We experienced a case of retroperitoneal cystic DDLP diagnosed by percutaneous image-guided biopsy and treated appropriately based on the pathological diagnosis.
RESUMO
BACKGROUND/AIM: The association of clinical outcomes with posttreatment persistent changes in eosinophils and other white blood cell (WBC) subtypes in patients with advanced urothelial cancer (UC) treated with pembrolizumab after the failure of platinum-based chemotherapy is unclear. PATIENTS AND METHODS: We retrospectively analyzed 87 patients with advanced UC who received pembrolizumab after the failure of platinum-based chemotherapy. The changes in WBC subtypes from pretreatment were evaluated three and six weeks after pembrolizumab administration. The association between the changes in the WBC subtypes and clinical outcomes was then evaluated using the Kaplan-Meier method and a Cox regression model. RESULTS: Among WBC subtypes, significant changes in the absolute (AEC) and relative eosinophil count (REC) and the neutrophil-to-eosinophil ratio (NER) were observed at three and six weeks compared with pretreatment (p<0.001). Multivariable Cox regression analyses revealed that a persistent decrease in AEC and REC and a persistent increase in NER were associated with poor overall survival. CONCLUSION: Persistent increase in AEC and REC and decrease in NER in the early phase after pembrolizumab may be significant early predictive markers of improved clinical outcomes in patients with advanced UC receiving pembrolizumab.
RESUMO
INTRODUCTION: Radium-223 (Ra-223) dichloride therapy increases overall survival and delays time to the first symptomatic skeletal event (SSE) in patients with castration-resistant prostate cancer (CRPC) and bone metastases. Bone-modifying agents (BMA) reduce SSE in patients with bone metastasis, but there is little information on their use with Ra-223. This study aimed to investigate the effect of BMA on SSE in patients with bone metastatic CRPC treated with Ra-223 in real-world practice. METHODS: We included 73 patients treated with Ra-223 from 10 institutions in Japan. Time to the first SSE was estimated using the Kaplan-Meier method and compared between groups using the log-rank test. We used univariate analysis to ascertain the association between variables and SSE. RESULTS: During a median follow-up of 12.7 months (interquartile range, 7-21.7), 12 (16.4%) patients presented SSE. Age and BMA use were different between men with and without SSE. The 1-year SSE-free survival rate from Ra-223 treatment initiation was 82.4% (95% CI, 69.4%-90.2%). BMA use was associated with favorable SSE-free survival (hazard risk, 0.23; 95% confidence interval, 0.061-0.85; p = 0.027). Two (4.7%) and seven (23.3%) patients presented symptomatic pathological bone fracture in groups with and without BMA use, respectively (p = 0.017). CONCLUSION: This study stresses the importance of BMA use in patients with CRPC and bone metastases in Ra-223 treatment.

Paralytic ileus as tuberculosis-immune reconstitution inflammatory syndrome (TB-IRIS) is extremely rare. We herein report a 44-year-old man with pulmonary and renal tuberculosis who developed paralytic ileus 14 days after starting antituberculosis therapy (ATT) despite an initial favorable response to ATT. Paralytic ileus was successfully managed with conservative care. He initially required hemodialysis because of obstructive uropathy due to renal tuberculosis, but he was able to withdraw from dialysis after placement of ureteral stents. TB-IRIS can affect organs other than the original sites of tuberculosis, and the combined use of steroids may be effective for its prevention and treatment.

OBJECTIVE: Radium-223 (Ra-223) dichloride is the bone-targeted radioligand therapy that prolongs overall survival (OS) in patients with bone-metastatic castration-resistant prostate cancer (CRPC). We aimed to evaluate the safety and effectiveness of this treatment in real-world practice. METHODS: We included Japanese men treated with Ra-223 for bone-metastatic CRPC from 10 institutions, retrospectively. Primary endpoint was OS. Secondary endpoint was maximum decline of alkaline phosphatase (ALP), lactate dehydrogenase, and prostate-specific antigen values, the rate of adverse events, and time to pathological fracture after Ra-223 treatment. Exploratory endpoint was the associations between clinical parameters and OS. RESULTS: In total, 73 men with bone metastatic CRPC treated with Ra-223 were enrolled. The median OS was 20.9 months. ALP levels decreased significantly from pre-treatment (p = 0.03). Anemia occurred in three (4.1%) patients. Grade ≥ 3 non-pathological fractures occurred in four (5.5%) men. Nine (12.3%) patients presented pathological fracture; 7/30 (23.3%) were in men without concomitant use of a bone-modifying agent (BMA) while 2/43 (4.7%) were in patients with concomitant BMA (p = 0.03). The median OS in patients with ≥3 cycles treatment (27.2 months, p < 0.001) or hemoglobin ≥12 g/dl (27.2 months, p = 0.001) or absence of bone pain (36.3 months, p = 0.004) was significantly longer compared to those who with ≤2 cycles or hemoglobin<12 g/dl or presence of bone paint, respectively. CONCLUSIONS: This study has shown the outcomes of Ra-223 treatment in real-world practice, where the number of treatment cycles, baseline anemia and bone pain may be useful to predict OS in Ra-223 treatment.

Background: To evaluate the eosinophil changes, efficacy and safety of pembrolizumab treatment in advanced urothelial carcinoma patients of older age and those with a poor performance status (PS). Materials and Methods: Consecutive patients with advanced UC who received pembrolizumab after the failure of platinum-based chemotherapy between January 2018 and June 2021 were retrospectively examined. Results: 105 patients (median age, 72 years), 71.4% of whom were men, were enrolled. Patients of ≥75 years of age were considered to be older patients (n=40), and patients with PS ≥2 were considered to have a poor PS (n=10). The objective response and disease control rates were 42.5% and 52.5%, respectively, in older patients and 0% and 10.0%, respectively, in patients with a poor PS. Overall survival (OS) in the older and younger groups did not differ to a statistically significant extent. However, a poor PS was significantly associated with poor survival. Safety analyses demonstrated no significant difference in the occurrence of any immune-related adverse events (irAEs), including grade ≥3, between the older and younger groups. However, a poor PS was significantly associated with the low occurrence of any irAEs. The change of the eosinophil count, the increase of the relative eosinophil count (REC) and the decrease of the neutrophil-to-eosinophil ratio (NER) did not differ to a statistically significant extent between the older and younger groups, but showed significant differences between the poor and good PS (PS 0-1) groups. Conclusion: Pembrolizumab for advanced UC demonstrated similar changes in the eosinophil count, efficacy and toxicity in both older and younger patients. In patients with a poor PS, although toxicity was significantly lower, survival was significantly worse, and neither an increase in REC nor a decrease in NER were observed, but these values showed significant changes in patients with a good PS.
RESUMO
To determine the course of treatment while considering the patients' desires, we examined trends regarding patients' perception and expectations over the course of cancer pharmacotherapy. We retrospectively reviewed interview sheets filled in by patients with advanced urogenital cancers when they started a new pharmacotherapy regimen between 2014 and 2020. The responses to the following questions were analyzed: 1) How did your doctor explain the treatment objectives?; 2) Are you willing to receive treatment?; and 3) When the standard treatment becomes difficult to continue, would you like to try another treatment even if it may cause severe side effects? A total of 277 patients answered the interview sheet. The percentage of patients who accurately perceived the treatment objectives among patients receiving 1st, 2nd, and 3rd line regimens was 67%, 79%, and 93%, respectively. The percentage significantly improved over the course of pharmacotherapy (p = 0.0057). The percentage of patients who indicated that they were willing to receive treatment in 1st, 2nd, and 3rd line regimens was 80%, 83%, and 86%, respectively. The percentage of patients who indicated that they wanted to try another treatment when the standard treatment became difficult to continue in 1st, 2nd, and 3rd line regimens was 56%, 64%, and 59%, respectively. The percentage of patients who accurately perceived the objective of pharmacotherapy increased over the course of pharmacotherapy. The rate of patients who were willing to receive treatment and try other treatments when the standard treatment became too difficult to continue remained consistently high.

Energy is continuously expended in the body, and gluconeogenesis maintains glucose homeostasis during starvation. Gluconeogenesis occurs in the liver and kidneys. The proximal tubule is the primary location for renal gluconeogenesis, accounting for up to 25% and 60% of endogenous glucose production during fasting and after a meal, respectively. The mechanistic target of rapamycin (mTOR), which exists downstream of the insulin pathway, plays an important role in regulating proximal tubular gluconeogenesis. mTOR is an atypical serine/threonine kinase present in two complexes. mTORC1 phosphorylates substrates that enhance anabolic processes such as mRNA translation and lipid synthesis and catabolic processes such as autophagy. mTORC2 regulates cytoskeletal dynamics and controls ion transport and proliferation via phosphorylation of SGK1. Therefore, mTOR signaling defects have been implicated in various pathological conditions, including cancer, cardiovascular disease, and diabetes. However, concrete elucidations of the associated mechanisms are still unclear. This review provides an overview of mTOR and describes the relationship between mTOR and renal.
RESUMO
INTRODUCTION: Metastases from renal cell carcinoma develop in various organs. However, the breadth of discrepancy in response to immune checkpoint inhibitors across tumor sites within the same individual remains unclear. PATIENTS AND METHODS: We reviewed 50 patients with metastatic renal cell carcinoma who had target lesions at multiple sites and received nivolumab monotherapy (n = 36) or nivolumab plus ipilimumab (n = 14). When the best overall response in tumor burden increased at one site but decreased at other sites, the response was defined as a dissociated response. The response was evaluated according to the Response Evaluation Criteria in Solid Tumors 1.1, and patients who met the definition of dissociated response were categorized as dissociated response. The rate of dissociated response and prognosis were evaluated. RESULTS: Eight of 36 (22%) and 4 of 14 (29%) patients treated with nivolumab and nivolumab plus ipilimumab were categorized as having dissociated response, respectively. The median overall survival of the patients treated with nivolumab was 20.2 months for those with a partial response, 6.8 months for those with stable disease, and 13.2 months for those with progressive disease, while dissociated response was not reached. There was no significant difference in the median overall survival between patients categorized as having progressive disease and those with dissociates response (P = 0.224). CONCLUSION: A certain proportion of patients with metastatic renal cell carcinoma show dissociated response when treated with immune checkpoint inhibitors. The prognosis of patients with dissociated response and progressive disease was not shown to be significantly different.
