RESUMO
Overcoming resistance to immune checkpoint inhibitors is an important issue in patients with non-small-cell lung cancer (NSCLC). Transcriptome analysis shows that adenocarcinoma can be divided into three molecular subtypes: terminal respiratory unit (TRU), proximal proliferative (PP), and proximal inflammatory (PI), and squamous cell carcinoma (LUSQ) into four. However, the immunological characteristics of these subtypes are not fully understood. In this study, we investigated the immune landscape of NSCLC tissues in molecular subtypes using a multi-omics dataset, including tumor-infiltrating leukocytes (TILs) analyzed using flow cytometry, RNA sequences, whole exome sequences, metabolomic analysis, and clinicopathologic findings. In the PI subtype, the number of TILs increased and the immune response in the tumor microenvironment (TME) was activated, as indicated by high levels of tertiary lymphoid structures, and high cytotoxic marker levels. Patient prognosis was worse in the PP subtype than in other adenocarcinoma subtypes. Glucose transporter 1 (GLUT1) expression levels were upregulated and lactate accumulated in the TME of the PP subtype. This could lead to the formation of an immunosuppressive TME, including the inactivation of antigen-presenting cells. The TRU subtype had low biological malignancy and "cold" tumor-immune phenotypes. Squamous cell carcinoma (LUSQ) did not show distinct immunological characteristics in its respective subtypes. Elucidation of the immune characteristics of molecular subtypes could lead to the development of personalized immune therapy for lung cancer. Immune checkpoint inhibitors could be an effective treatment for the PI subtype. Glycolysis is a potential target for converting an immunosuppressive TME into an antitumorigenic TME in the PP subtype.

OBJECTIVES: To investigate predictive factors and oncological outcomes of pathological T3a upstaging in renal cell carcinoma patients who were initially diagnosed as clinical T1 and treated with partial nephrectomy. METHODS AND MATERIALS: The clinical records and survival data of 1617 patients, who had undergone partial nephrectomy for clinical T1 renal cell carcinoma at Tokyo Women's Medical University, Tokyo, Japan between January 2011 and December 2020, were analyzed retrospectively. RESULTS: Of 1617 clinical T1 renal cell carcinoma patients who underwent partial nephrectomy, 28 (1.73%) had pathological T3a upstaging. In the multivariable analysis for pathological T3a upstaging using logistic regression models, male sex and clinical T1b were significant factors associated with pathological T3a upstaging (male sex: odds ratio = 5.07, 95% confidence interval: 1.18-21.8, clinical T1b: odds ratio = 8.36, 95% confidence interval: 3.56-19.6). The Kaplan-Meier method of the recurrence-free survival showed shorter recurrence-free survival in patients with pathological T3a upstaging than in those with pathological T1 (P < 0.0001). In the multivariable analysis using Cox proportional hazards regression models, pathological T3a upstaging was no longer significantly associated with recurrence-free survival after adjustment for other pathological factors (hazard ratio = 1.59, 95% confidence interval: 0.58-4.36). In a sensitivity analysis that analyzed its components individually instead of whole pathological T3a, neither perinephric fat invasion, sinus fat invasion, nor renal vein invasion was associated with recurrence-free survival. CONCLUSIONS: Male sex and clinical T1b were significant predictors for pathological T3a upstaging after partial nephrectomy in clinical T1 renal cell carcinoma patients. Although patients with pathological T3a upstaging had worse recurrence-free survival compared with those without upstaging, multivariable analyses revealed that pathological T3a upstaging was not an independent predictor for poor recurrence-free survival.

BACKGROUND: Long-term follow-up data regarding treatment outcomes of nivolumab plus ipilimumab combination therapy for advanced renal cell carcinoma as a first-line therapy are limited in real-world Japanese populations. METHODS: We retrospectively evaluated data of 56 advanced renal cell carcinoma patients treated with nivolumab plus ipilimumab, with a follow-up of at least 3 years. Survival, tumour response and adverse event profiles were assessed. RESULTS: A total of 41 patients (73%) were histopathologically diagnosed with clear-cell renal cell carcinoma, and 34 (61%) were categorized into the International Metastatic renal cell carcinoma Database Consortium intermediate-risk group. The median follow-up period was 34.4 months. Regarding an effectiveness profile, median progression-free survival, time to treatment failure and overall survival were 9.01, 12.5 and 49.0 months, respectively. Objective response was observed in 27 patients (48%), including eight patients with complete response (14%), and the median duration of response was 30.8 months. Multivariate analyses showed that clear-cell histology was an independent factor of longer overall survival (hazard ratio: 0.23, P = 0.0013). Regarding safety profiles, adverse events of any grade and those with grade ≥3 developed in 40 (71%) and 25 patients (45%), respectively. Median time to adverse event development was 1.68 months. Treatment was interrupted in 28 patients (50%), and corticosteroid administration was needed in 25 (45%). CONCLUSION: The 3-year follow-up data showed that nivolumab plus ipilimumab combination therapy exhibited a feasible effectiveness in real-world Japanese patients with advanced renal cell carcinoma. Accordingly, the high risk of adverse event development, which often requires treatment withdrawal and corticosteroid administration, should be considered.

BACKGROUND: Whether immune checkpoint inhibitor (ICI) plus ICI combination therapy or ICI plus tyrosine kinase inhibitor (TKI) combination therapy is useful for renal cell carcinoma (RCC) with inferior vena cava tumor thrombosis (IVCTT) remains unclear. METHODS: We retrospectively evaluated the therapeutic effects and incidence of treatment-related adverse events (TRAEs) associated with ICI-based combination therapy in 36 patients with advanced RCC with IVCTT. RESULTS: The median age at initiation of treatment was 71 years; the IVCTT stages were cT3b in 22 patients and cT3c in 14. The ICI-ICI and ICI-TKI groups comprised 15 and 21 patients, respectively. Median tumor shrinkage at the best response showed that the primary tumor diameter decreased by 1.8 cm (22%), and the IVCTT height decreased by 1.5 cm (26%). A higher proportion of patients in the ICI-TKI group experienced tumor shrinkage than those in the ICI-ICI group (primary tumor, p = 0.0325; IVCTT, p = 0.0112). Approximately 27% of patients experienced an increase in the IVCTT height with ICI-ICI combination therapy. No significant difference was observed in the relative tumor shrinkage of IVCTT, primary or level-down staging of IVCTT, other treatment effects, incidence of TRAEs, surgical outcomes, or prognosis between the groups. CONCLUSION: ICI-based combination therapy is effective against IVCTT and primary RCC. Although ICI-ICI is associated with a higher probability of tumor growth compared with ICI-TKI in the frequency of tumor regression, both therapies may be almost equally effective against primary RCC with IVCTT.
RESUMO
BACKGROUND: There are few comparative studies on dual immune checkpoint inhibitors (ICIs) (i.e., IO-IO) and combination therapies comprising ICIs plus tyrosine kinase inhibitors (TKIs) (i.e., IO-TKI) for advanced renal cell carcinoma (RCC), especially in real-world settings. METHODS: We retrospectively evaluated data of 175 patients with IMDC intermediate-risk or poor-risk RCC; as first-line therapy, 103 received IO-IO, and 72 received IO-TKI. An inverse probability of treatment weighting (IPTW) analysis was conducted to balance patients' backgrounds in the IO-IO and IO-TKI groups. RESULTS: Based on the IPTW analysis, progression-free survival (PFS) was longer in the IO-TKI group than in the IO-IO group (median: 15.6 vs. 8.3 months; p = 0.0386). In contrast, overall survival was not different between groups (median: 46.7 vs. 49.0 months; p = 0.465). Although the IPTW-adjusted objective response rate was not significantly different (51.2% vs. 43.9%; p = 0.359), the progressive disease rate as the best overall response was lower in the IO-TKI group than in the IO-IO group (3.3% vs. 27.4%; p < 0.0001). Regarding the safety profile, the treatment interruption rate was higher in the IO-TKI group than in the IO-IO group (70.3% vs. 49.2%; p = 0.005). In contrast, the IO-IO group had a higher corticosteroid administration rate (43.3% vs. 20.3%; p = 0.001). CONCLUSION: IO-TKI therapy exhibited superior effectiveness over IO-IO therapy in terms of PFS improvement and immediate disease progression prevention and was associated with a higher risk of treatment interruption and a lower risk of needing corticosteroids.

OBJECTIVES: The objective of the study was to analyze the outcomes of patients with renal cell carcinoma (RCC) arising in end-stage renal disease (ESRD) over a 40-year span. METHODS: We retrospectively evaluated data of patients with ESRD-RCC diagnosed between 1979 and 2020 at two institutions. We assessed changes in stage, surgical approaches, and cancer-specific survival (CSS) following nephrectomy according to era between ESRD-RCC and sporadic RCC. Furthermore, perioperative outcomes in patients with ESRD-RCC were compared between laparoscopic and open surgery. RESULTS: Patients with ESRD-RCC (n = 549) were diagnosed at an earlier stage (p = 0.0276), and the ratio of laparoscopic nephrectomy was increased (p < 0.0001) according to eras. Since 2000 (i.e., after implementation of laparoscopic nephrectomy), patients with ESRD-RCC (n = 305) had significantly shorter CSS (p = 0.0063) after nephrectomy than sporadic RCC (n = 2732). After adjustment by multivariate analysis and propensity score matching, ESRD status was independently associated with shorter CSS (p = 0.0055 and p = 0.0473, respectively). Improved CSS in sporadic RCC (p < 0.0001), but not ESRD-RCC (p = 0.904), according to era contributed to this difference. Laparoscopic nephrectomy showed favorable outcomes, including shorter surgery time, lower estimated bleeding volumes, transfusion rates, and readmission rates, and shorter postoperative hospitalization than open nephrectomy (p < 0.05). CONCLUSIONS: Advances in diagnostic and treatment modalities potentially enable early diagnosis and minimally invasive surgery for patients with ESRD-RCC. As ESRD-RCC may not present indolently, careful post-operative monitoring is needed.

OBJECTIVES: To examine the surgical and functional outcomes of patients who have undergone repeat open partial nephrectomy (reOPN) or robot-assisted laparoscopic partial nephrectomy (reRAPN). METHODS: Until May 2022, 3310 patients with renal tumors underwent nephron-sparing surgery (NSS) at affiliated institutions. Of these, 22 and 17 patients who underwent reOPN and reRAPN, respectively, were included in this study. RESULTS: No significant differences were found between the groups in terms of sex, age, comorbidities, recurrent tumor size at repeat NSS, interval from recurrence to initial NSS, and nephrometry score. ReRAPN had a shorter operative time (median: 138.0 vs. 214.0 min; p = 0.0023) and less estimated blood loss (median: 50.0 vs. 255.0 mL; p = 0.0261) than reOPN. The incidence of complications with Clavien-Dindo grade ≥ 2 was higher in the reOPN group than in the reRAPN group (31.8 vs. 5.9%; p = 0.0467). The mean decrease in the estimated glomerular filtration rate at 3 months postoperatively was not significantly different between the groups. The trifecta achievement rates in the reRAPN (64.7%) and reOPN (27.3%) groups were significantly different (p = 0.0194). On multivariate analysis, age and surgical method were significant predictors of trifecta achievement after partial nephrectomy. CONCLUSIONS: There were no differences in postoperative renal functional outcomes between reOPN and reRAPN. ReRAPN is superior to reOPN in terms of surgical burden. Therefore, ReRAPN is an important minimally invasive surgery for recurrent renal cell carcinoma.

BACKGROUND: Real-world data of cabozantinib after failure of immune checkpoint inhibitors for advanced renal cell carcinoma in Japanese population are limited. Additionally, prognostic factors of cabozantinib in this setting are still unknown. METHODS: We retrospectively evaluated data of 56 patients treated with cabozantinib subsequent to failed immune checkpoint inhibitors at four institutions. Regarding the efficacy profile, progression-free survival, overall survival and objective response rate were assessed. In terms of the safety profile, rate of adverse events, dose reduction and treatment interruption were assessed. Furthermore, risk factors of progression-free survival were analyzed. RESULTS: Twenty-nine patients (52%) were treated with cabozantinib as second-line therapy. Most frequent prior immune checkpoint inhibitor treatment was nivolumab plus ipilimumab combination therapy as first-line therapy (n = 30, 54%). Median progression-free survival and overall survival were 9.76 and 25.5 months, respectively, and objective response rate was 34%. All patients experienced at least one adverse event, and grade ≥ 3 adverse events were observed in 31 patients (55%). Forty-four (79%) and 31 (55%) patients needed dose reduction and treatment interruption, respectively. Multivariate analysis showed that reduced initial dose (i.e. <60 mg) (hazard ratio: 2.50, P = 0.0355) and presence of lymph node metastasis (hazard ratio: 2.50, P = 0.0172) were independent factors of shorter progression-free survival. CONCLUSION: Cabozantinib in Japanese patients with advanced renal cell carcinoma who failed immune checkpoint inhibitors was efficacious and had a manageable safety profile. These results appear to be similar to those of previous clinical trials.

BACKGROUND: Prognostic impact of sex in patients with malignancies treated with immune checkpoint inhibitors has been intensively discussed but remains unclear, especially in advanced renal cell carcinoma. METHODS: We retrospectively evaluated a total of 184 patients with advanced renal cell carcinoma treated with either nivolumab plus ipilimumab combined treatment as first-line therapy (n = 73) or nivolumab as later-line therapy (n = 111) at our affiliated institutions. Progression-free survival, overall survival and objective response rate as well as adverse event profile were compared between sexes. RESULTS: Of the total 184 patients, 48 (26%) were female. Female patients had a significantly shorter progression-free survival than male patients (median: 3.8 vs. 8.3 months, P = 0.0005), but overall survival (median: 39.2 vs. 45.1 months, P = 0.283) and objective response rate (29% vs. 42%, P = 0.119) were not different between them. Similar findings were observed when analyzing within each treatment; in both patient groups treated with nivolumab plus ipilimumab combined therapy and nivolumab monotherapy, progression-free survival was significantly shorter in female than in male patients (P = 0.007, P = 0.017), but overall survival (P = 0.914, P = 0.117) and objective response rate (P = 0.109, P = 0.465) were comparable between them. Moreover, in a more restricted cohort consisting of patients with clear-cell renal cell carcinoma, a shorter progression-free survival in female patients was also observed (3.8 vs. 11.0 months, P < 0.0001). CONCLUSIONS: This retrospective study showed that immune checkpoint inhibitors-based treatment for renal cell carcinoma exhibited less marked effects in female than in male patients. Thus, sex may be an important factor for decision-making on systemic therapy as renal cell carcinoma treatment, although further studies are required to validate the present findings.

INTRODUCTION AND OBJECTIVE: Lung immune prognostic index score (LIPI), calculated using the derived neutrophil-lymphocyte ratio and lactate dehydrogenase level, is reported for use in numerous malignancies, while its role on metastatic urothelial carcinoma (mUC) treated with pembrolizumab remains limited. We aimed to investigate association between LIPI and outcomes in this setting. METHODS: We retrospectively evaluated 90 patients with mUC treated with pembrolizumab at four institutions. The associations between three LIPI groups and progression-free survival (PFS), overall survival (OS), objective response rates (ORRs) or disease control rates (DCRs) were assessed. RESULTS: Based on the LIPI, good, intermediate, and poor groups were observed in 41 (45.6%), 33 (36.7%), and 16 (17.8%) patients, respectively. The PFS and OS were significantly correlated with the LIPI (median PFS: 21.2 vs. 7.0 vs. 4.0 months, p = 0.001; OS: 44.3 vs. 15.0 vs. 4.2 months, p < 0.001 in the LIPI good vs. intermediate vs. poor groups). Multivariable analysis further revealed that LIPI good (vs. intermediate or poor, hazard ratio: 0.44, p = 0.004) and performance status = 0 (p = 0.015) were independent predictors of a longer PFS. In addition, LIPI good (hazard ratio: 0.29, p < 0.001) were shown to be associated with a longer OS together with performance status = 0 (p < 0.001). The ORRs tended to be different among patients with Good LIPI compared with Poor, and DCRs were significantly different among the three groups. CONCLUSIONS: LIPI, a simple and convenient score, could be a significant prognostic biomarker of OS, PFS, and DCRs for mUC treated with pembrolizumab.

Transplantation outcomes are affected by the increase in rejection associated with ischemia reperfusion injury (IRI). Fractalkine (FKN), a chemokine for recruitment of CX3CR1+ leukocytes, contributes to the pathogenesis of various inflammatory diseases. Herein, we evaluated the importance of the FKN-CX3CR1 axis during IRI-related rejections using a mouse heterotopic heart transplantation model. FKN expression and graft survival was compared between wild-type C57BL/6 recipients transplanted with BALB/c hearts preserved for 8 (WT-IRI) and 0.5 h (WT-control) at 4°C. Graft survival of WT-IRI was shorter than that of WT-control. FKN was expressed on the vascular endothelium in WT-IRI allografts, but minimally in WT-control. The role of the FKN-CX3CR1 axis in IRI-related rejection was directly investigated using the transplant model with CX3CR1-deficient recipients (CX3CR1 KO-IRI) or treatment with anti-mouse FKN monoclonal antibodies. Graft survival of CX3CR1 KO-IRI was longer than that of WT-IRI; antibody treatment prolonged graft survival. The contribution of CX3CR1+ monocytes to IRI-related rejection was evaluated by adoptive transfer to CX3CR1 KO-IRI. Adoptive transfer of CX3CR1+ monocytes attenuated the effect of prolonged graft survival in CX3CR1 KO-IRI. Overall, the FKN-CX3CR1 axis plays a major role during IRI-related rejection; its blockade has the potential to improve the outcomes of deceased donor transplantation.

OBJECTIVES: To investigate the long-term follow-up outcomes of nivolumab monotherapy for previously treated metastatic renal cell carcinoma, using real-world data. METHODS: A total of 121 patients were treated with nivolumab monotherapy as subsequent therapy after the failure of prior tyrosine kinase inhibitor therapy between January 2013 and December 2021 at four affiliated institutions. To evaluate the outcome after 2 years or more, we selected patients in whom nivolumab therapy was started in December 2019 or earlier because data collection was performed until the end of December 2021. RESULTS: Seventy-four patients were evaluated. During the median follow-up period of 25.8 months, 62 (84%) and 40 (54%) patients had disease progression and died, respectively. Nivolumab was administered as second-line therapy in 43 patients (58%). The median progression-free survival and overall survival were 5.52 and 31.1 months, respectively, and objective response rate was 36%. There was no difference in progression-free survival or overall survival based on the treatment line of nivolumab (P = 0.915, P = 0.559). The magnitude of tumor response and development of immune-related adverse events were significantly associated with progression-free survival (P < 0.0001, P < 0.0001, respectively) and overall survival (P < 0.0001, P = 0.0002, respectively). Treatment-related adverse events developed in 38 patients (51%), including 33 (45%) who had immune-related adverse events. Steroid administration was needed in nine patients (12%). CONCLUSIONS: The present real-world multi-institution study with long-term follow-up data demonstrates that nivolumab monotherapy is effective for previously treated metastatic renal cell carcinoma, prolonging survival, improving tumor response and has a manageable safety profile.

OBJECTIVES: To explore the therapeutic role of deferred cytoreductive nephrectomy in patients with metastatic renal cell carcinoma treated with nivolumab plus ipilimumab. PATIENTS AND METHODS: Forty-one patients with synchronous metastatic renal cell carcinoma who received nivolumab plus ipilimumab as first-line systemic therapy at our affiliated institutions were retrospectively evaluated. We focused on the prognosis, including tumor responses in primary kidney and metastatic lesions in patients treated with deferred cytoreductive nephrectomy. In addition, the overall survival according to nephrectomy status (i.e. deferred cytoreductive nephrectomy vs. upfront cytoreductive nephrectomy vs. without cytoreductive nephrectomy) was compared. RESULTS: During a median follow-up period of 12.0 months, seven (30%) patients received deferred cytoreductive nephrectomy at a median time of 10.4 months after nivolumab plus ipilimumab initiation. All the patients showed tumor shrinkage in their primary kidney lesions, including six (86%) patients with ≥30% of shrinkage. Metastatic lesions were also shrunk by ≥30% in six (86%) patients, including two (29%) obtaining complete response. At the last time of follow-up, three (43%) patients were disease-free. The overall survival rate after nivolumab plus ipilimumab initiation tended to be higher in patients with deferred cytoreductive nephrectomy compared with those with upfront cytoreductive nephrectomy (1-year survival rate: 100% vs. 72.4%, P = 0.0587) and those without cytoreductive nephrectomy (vs. 58.2%, P = 0.0613). CONCLUSIONS: The present retrospective data showed that deferred cytoreductive nephrectomy had the potential to exert a therapeutic effect in a subset of patients who obtained favorable tumor responses to nivolumab plus ipilimumab for a certain period. Prospective randomized clinical trials are needed to confirm the prognostic impact of deferred cytoreductive nephrectomy after frontline immunotherapy in synchronous metastatic renal cell carcinoma.

BACKGROUND: Cancer development in adolescents and young adults (AYAs) has elicited recent interest. We investigated the surgical and functional outcomes of robot-assisted laparoscopic partial nephrectomy (RAPN) for renal cell carcinoma (RCC) in AYAs. METHODS: We retrospectively reviewed the medical records of 1023 patients with clinical stage I RCC who underwent RAPN before January 2021. Patients were divided into two groups: AYAs (aged 18-39 years) and non-AYAs (aged 40-89 years). The trifecta criteria, defined as a negative surgical margin, no perioperative complications (Clavien-Dindo grade > 2), and preserved postoperative renal function (1-year postoperative estimated glomerular filtration rate > 90% of baseline), were used to compare outcomes. We performed 1:1 propensity-score matching on the patient cohort. RESULTS: There were initially 125 and 898 patients in the AYAs and non-AYAs groups, respectively, and 108 patients were included in each group after propensity score matching. There were no significant differences in surgical factors (operation time, clamping ischemia time, estimated blood loss, length of hospital stay, surgical complication rate) or renal function in the early postoperative period. The mean postoperative renal function was better (p = 0.0200) and the decrease in estimated glomerular filtration rate was lower (p = 0.0026) in AYAs than in non-AYAs 12 months postoperatively. The trifecta achievement rates in the AYAs and non-AYAs groups were significantly different (67.6% and 53.7%, respectively, p = 0.0220). CONCLUSION: Although there was no difference in surgical burden between the groups, the estimated glomerular filtration rate was better preserved in AYAs than in non-AYAs at 6 and 12 months post-RAPN.

OBJECTIVE: The aim of the study was to evaluate the prognostic impact of trial-eligibility criteria on outcome in real-world metastatic renal cell carcinoma (mRCC) patients treated with tyrosine kinase inhibitors (TKIs). PATIENTS AND METHODS: mRCC patients treated with TKIs as first-line systemic therapy were retrospectively evaluated. The patients were determined as trial-ineligible when they met at least 1 following trial-ineligible criteria; Karnofsky performance status score <70, hemoglobin <9.0 g/dL, creatinine >2.4 mg/dL (male) or >2.0 mg/dL (female), calcium >12.0 mg/dL, platelet <100,000 /µL, neutrophil <1,500 /µL, nonclear-cell histology, and brain metastasis. RESULTS: Of 238 patients, 101 patients (42%) were determined as trial-ineligible. Progression-free survival (PFS) and overall survival (OS) after the TKI initiation were significantly shorter in the trial-ineligible patients than in the trial-eligible patients (median PFS: 5.53 vs. 15.8 months, p < 0.0001; OS: 13.8 vs. 43.4 months, p < 0.0001). Objective response rate was also significantly lower in the trial-ineligible patients (15% vs. 37%, p = 0.0003). Multivariate analysis further showed that the trial-eligibility was an independent factor for PFS (hazard ratio [HR]: 2.46, p < 0.0001) and OS (HR: 2.39, p < 0.0001). In addition, the number of trial-ineligible factors were negatively correlated with PFS and OS. CONCLUSIONS: In real-word, the substantial number of mRCC patients did not meet the trial-eligibility criteria, and their outcome was worse than that in the trial-eligible patients. Further studies focusing on the outcome in real-world trial-ineligible patients in the immune checkpoint inhibitor era are warranted.

PURPOSE: We investigated operative time according to procedure phases in robot-assisted laparoscopic partial nephrectomy (RAPN) and identify variables associated with longer operative time in each procedure phase. METHODS: This retrospective, single-center study included 108 patients who underwent RAPN conducted by an experienced surgeon. Operative time was divided into dissection, resection, tumor bed suture, and renorrhaphy and hemostasis phases, which were derived from the iPhone application "My Intuitives." Multivariate analyses were performed to identify possible predictors such as sex, body mass index, tumor complexity, and surgical approach for longer operative time in each phase. RESULTS: The median console time was 65 min, and median operative times in dissection, resection, tumor bed suture, and renorrhaphy and hemostasis phases were 41, 8, 9, and 8 min, respectively. In the multivariate analysis, longer console time was observed in high complexity tumors (vs. low, OR: 8.01, 95% CI: 1.94-33.0) and transperitoneal approach (vs. retroperitoneal approach, OR: 3.62, 95% CI: 1.94-33.0). High complexity tumors were significantly associated with longer operative time in all procedure phases, and the male sex was associated with a longer operative time in the dissection phase than the female sex (OR: 3.61, 95% CI: 1.18-11.0). CONCLUSION: The identified significant predictive factors associated with longer operative time were the male sex and high complexity in the dissection phase, high complexity in the resection phase, in the tumor bed suture phase as well as in the renorrhaphy and hemostasis phase. These findings may help to predict the difficulty of performing RAPN in terms of operative time.

OBJECTIVE: We investigated the incidence of hypopituitarism in Japanese patients with metastatic renal cell carcinoma (mRCC) who received ipilimumab and nivolumab (I-P) therapy and compared patient characteristics and survival rates between patients with hypopituitarism and those without. METHODS: Twenty-two patients with mRCC who received I-P therapy as first-line treatment were the subjects of this retrospective study. The diagnosis of hypopituitarism was based on the hormone loading test. RESULTS: Hypopituitarism occurred in 41% (9/22) patients who received I-P therapy. Median time of diagnosis was 12 weeks (IQR: 9.5-20). Clinical symptoms, such as fatigue, weakness or fever, were observed in 7 patients, while 2 patients had no clinical presentation. The following deficiency patterns were observed: isolated ACTH in 4 patients, ACTH and GH in 2 patients, ACTH and TSH in 2 patients and triple deficiency (ACTH, GH and TSH) in 1 patient. All patients with hypopituitarism were in the IMDC intermediate group, while 46% of those without hypopituitarism were in the IMDC intermediate group. Other patient characteristics were not different between the two groups. Object response rate was 33% (3/9) in patients with hypopituitarism and 23% (3/13) in those without (P = 0.5954). Progression free survival (PFS) was significantly longer in those with hypopituitarism than those without (median: 24.7 vs. 4.5 months, P = 0.0008), while overall survival did not differ (P = 0.136). CONCLUSIONS: Compared with the clinical trial, the incidence of hypopituitarism was higher than expected. Patients with hypopituitarism tended to have longer PFS, which may suggest that optimal management of hypopituitarism results in better prognosis.

OBJECTIVE: Sarcopenia is associated with oncological outcomes in various types of cancer. However, the impact of sarcopenia in renal cell carcinoma with inferior vena cava thrombus remains unclear. We herein evaluated the prognostic significance of sarcopenia for renal cell carcinoma with inferior vena cava thrombus following nephrectomy and thrombectomy. METHODS: Patients who underwent nephrectomy and thrombectomy for renal cell carcinoma with inferior vena cava thrombus at our department between 2004 and 2019 were retrospectively evaluated. Their sarcopenic status, determined by sex, body mass index and skeletal muscle index, was calculated using pre-surgical radiographic imaging. We compared the post-operative cancer-specific survival and overall survival, surgical data and duration of post-operative hospitalization of sarcopenic and non-sarcopenic patients. RESULTS: Out of 83 patients, 54 (65%) were sarcopenic. Sarcopenic patients had significantly shorter cancer-specific survival (median: 33.3 months vs. not reached, P = 0.0323) and overall survival (32.0 months vs. not reached, P = 0.0173) than non-sarcopenic patients. Furthermore, multivariate analyses showed that sarcopenia was an independent factor for cancer-specific survival (hazard ratio: 2.76, P = 0.0212) and overall survival (hazard ratio: 2.93, P = 0.014). The incidence rate of surgical complications (any grade: 35.2% vs. 27.6%, P = 0.482; grades ≥ 3: 7.4% vs. 10.3%, P = 0.648) or duration of post-operative hospitalization (median: 11 vs. 10 days, P = 0.148) was not significantly different between sarcopenic and non-sarcopenic patients. CONCLUSIONS: In conclusion, this study showed that sarcopenia was an independent prognostic factor for renal cell carcinoma with inferior vena cava thrombus after nephrectomy and tumor thrombectomy. Thus, sarcopenia evaluation can be utilized as an effective prognosticator of post-operative survival.

OBJECTIVE: Limited data are available regarding the effect of systemic therapy change in the post-cytokine era on survival of metastatic renal cell carcinoma (mRCC) patients undergoing cytoreductive nephrectomy (CN). METHODS: Overall, 161 patients with synchronously mRCC were retrospectively evaluated. The patients were classified into three groups based on the time of diagnosis: (i) early molecular-targeted therapy (mTT) (2008-2011), (ii) late mTT (2012-8/2016) and (iii) immune checkpoint inhibitor (ICI) eras (9/2016-2018). Overall survival (OS) after the diagnosis was compared among the eras. RESULTS: Of the 161 patients, 52 (32%), 75 (46%), and 34 patients (21%) were classified into the early mTT, late mTT and ICI eras, respectively. OS was significantly longer in the ICI and late mTT eras than that in the early mTT era (P = 0.0065 and P = 0.0010, respectively) but did not significantly differ between the ICI and late mTT eras (P = 0.389). In 112 patients undergoing CN and systemic therapy, OS was significantly longer in the ICI and late mTT eras than that in the early mTT era (P = 0.0432 and P = 0.0498, respectively) but did not significantly differ between the ICI and late mTT eras (P = 0.320). Multivariate analysis of OS in the 161 synchronous mRCC patients revealed that the era was an independent factor (P < 0.0001), together with the histopathological type (P = 0.0130), CN status (P = 0.0010), International Metastatic Renal Cell Carcinoma Database Consortium risk (P = 0.0002) and liver metastasis status (P = 0.0124). CONCLUSION: This retrospective analysis showed that systemic therapy change in the post-cytokine era improved OS of mRCC patients undergoing CN.

OBJECTIVE: Studies assessing outcome improvements over a long period according to systemic therapy strategies for metastatic renal cell carcinoma using real-world data, including the results of the recent era of immune checkpoint inhibitors, are limited. Herein, we retrospectively evaluated patients who were diagnosed with metastatic renal cell carcinoma over a 40-year span. METHODS: Patients were classified into four groups based on when their metastases were diagnosed as follows: (i) the pre-cytokine era (1980-1986), (ii) the cytokine era (1987-2007), (iii) the molecular-targeted therapy (mTT) era (2008 to August 2016) and (iv) the immune checkpoint inhibitor era (September 2016 to 2018). The immune checkpoint inhibitor era consisted of second- or later-line nivolumab. Overall survival from the diagnoses of metastases was evaluated. RESULTS: In total, 576 patients were evaluated, including 22 (3.82%), 231 (40.1%), 253 (43.9%) and 70 (12.2%) patients from the pre-cytokine, cytokine, molecular-targeted therapy and immune checkpoint inhibitor eras, respectively. The overall survival significantly improved with each successive era (median: 13.1 vs. 24.5 vs. 44.4 months vs. not reached in pre-cytokine vs. cytokine vs. molecular-targeted therapy vs. immune checkpoint inhibitor eras, P < 0.0001). The implementation of molecular-targeted therapy improved overall survival compared with that of cytokine (cytokine vs. molecular-targeted therapy eras, P < 0.0001). Multivariate analysis demonstrated that the era was an independent factor for overall survival (P < 0.0001), together with histopathological type; metastasis status (i.e. synchronous or metachronous); systemic therapy status (i.e. absence or presence) and bone, liver or lymph node metastasis status (all, P < 0.05). CONCLUSION: This retrospective study of real-world data indicated that metastatic renal cell carcinoma outcomes improved with successive systemic therapy paradigms.
