Background Adrenocortical carcinoma is an aggressive tumor which often recurs despite apparent complete resection. This study assessed the long-term outcomes for patients with recurrent adrenocortical carcinoma after multimodal salvage therapy with chemotherapy, chemoradiotherapy and surgery. Methods We retrospectively reviewed medical records of patients who had a pathological diagnosis of adrenocortical carcinoma between 1996 and 2017. Kaplan–Meier curves were used to assess progression-free and cancer-specific survivals among all patients and cancer-specific survival among patients with tumor recurrence. Log-rank test was used to compare patient survivals by modality of salvage therapy (chemotherapy, chemoradiotherapy and chemotherapy/chemoradiotherapy plus surgery). Results Of 20 patients who underwent initial surgery, recurrence occurred in 14 (70%) with a median interval of 7.5 (range 1.0–12.6) months. Salvage therapy provided was chemotherapy only (n = 7), chemoradiotherapy (n = 2) and chemotherapy/chemoradiotherapy plus surgery (n = 5). Of the five patients who received salvage surgery, three underwent repeated resections. The potential benefit of multimodal salvage therapy was suggested in five patients (4 with chemotherapy/chemoradiotherapy plus surgery and 1 with chemoradiotherapy) who achieved durable disease control (cancer-specific survival from initial recurrence, 22–258 months). With a median follow-up of 25 months from recurrence, the 5-year cancer-specific survival rate was 58%. cancer-specific survival after recurrence was prolonged in patients with ≤ stage 3 disease, positive response to chemotherapy/chemoradiotherapy and salvage surgery. Conclusions Long-term disease control and survival could be achieved in highly selected patients with recurrent adrenocortical carcinoma using a multidisciplinary approach. Patients who had relatively limited recurrent sites and responded well to chemotherapy/chemoradiotherapy may be considered for salvage surgery on a case-by-case basis.

To describe oncological outcomes after progressive site-directed therapy (PSDT) in genuine and induced oligometasatic (OM)-castration-resistant prostate cancer (CRPC).Thirty-seven patients with OM-CRPC treated with PSDT were retrospectively analyzed, and oncological outcomes and recurrence patterns on whole-body diffusion-weighted MRI (WB-DWI) were evaluated.Twenty-two (59%) were classified as genuine OM-CRPC and 15 (41%) as induced OM-CRPC. A 50% decline in PSA after PSDT was observed in 21 (95%) genuine OM-CRPCs and 7 (47%) induced OM-CRPCs (p = 0.0005). At a median observation period of 7.3 months, median PSA progression-free survival were 10.9 months in the genuine OM-CRPCs and 4.8 months in the induced OM-CRPCs (p = 0.015). Among the patients who developed PSA progression after PSDT, 11 of 15 in the genuine OM-CRPCs (73%) and 11 of 14 in the induced OM-CRPCs (79%) underwent WB-DWI at PSA progression. The median numbers of newly detected metastases were 2 (range: 1-5) in the genuine OM-CRPCs and 4 (range: 1-40) in the induced OM-CRPCs (p = 0.049). Only one new metastasis appeared in 5 patients from the genuine OM-CRPCs (46%) and 1 from the induced OM-CRPCs (9.1%, p = 0.048). In 7 of 9 patients from the genuine OM-CRPCs (78%) and 7 of 8 patients from the induced OM-CRPCs (88%) who had bone metastases alone, the newly detected metastasis limited to the bone.Genuine OM-CRPC had better oncological outcomes after PSDT than induced OM-CRPC, and the number of lesions detected at recurrence was limited. Induced OM-CRPC might be a disseminated condition with micrometastases at OM diagnosis.

Background: Immune-related adverse events (irAEs) in patients treated with immune check inhibitors are associated with favourable response rate and survivals in multiple cancers, including renal cell carcinoma (RCC). The aim of this study was to investigate how irAEs were associated with improved survivals in advanced RCC patients treated with nivolumab plus ipilimumab. Materials and methods: This retrospective study included patients who received nivolumab plus ipilimumab between September 2018 and February 2022 at six centres. We assessed associations of the development and the number of irAEs with overall survival (OS) and progression-free survival (PFS). To eliminate immortal time bias, landmark analysis and a Cox model with time-dependent variables were used. Results: This study included 129 patients with a median follow-up of 12.3 months. The 2-year OS and PFS rates were 55% and 42%, respectively. Ninety six patients experienced irAEs. The development of irAEs was positively associated with OS and PFS rates (hazard ratio [HR] 0.328, 95% confidence interval [CI] 0.165–0.648, p = 0.001; HR 0.334, 95% CI 0.151–0.737, p = 0.007). Patients who experienced multiple irAEs had longer OS (HR 0.507, 95% CI 0.235–1.097, p = 0.085 or HR 0.245, 95% CI 0.110–0.544, p < 0.001) and PFS (HR 0.572, 95% CI 0.316–1.036, p = 0.085 or HR 0.267, 95% CI 0.113–0.628, p = 0.002) compared with those who experienced single or zero irAE. Conclusions: Developing irAEs, particularly multiple irAEs, is associated with favourable survivals in advanced RCC patients treated with nivolumab plus ipilimumab.

Prostate cancer localization is reportedly associated with the laterality of lymph node metastasis. Thus, it may be feasible to predict side-specific lymph node metastasis (LNM) at radical prostatectomy (RP). To investigate whether multiparametric magnetic resonance imaging and biopsy findings can predict side-specific negative LNM and to explore the feasibility of unilateral lymph node dissection (LND) at RP.A total of 500 patients who were diagnosed with prostate cancer with prebiopsy multiparametric magnetic resonance imaging of the prostate and subsequent prostate biopsy and who underwent RP and extended LND without neoadjuvant treatment were enrolled. Multiparametric magnetic resonance imaging, biopsy findings, and LNM were assessed for each side. The negative predictive value (NPV) of multiparametric magnetic resonance imaging or biopsy or both for ipsilateral LNM was examined.LNM was found in 9.2% (46/500) and 15.6% (28/180) of patients in the overall and high-risk cohorts, respectively. Magnetic resonance imaging and biopsy findings were negative in 408 and 262 sides, respectively, in the overall cohort and 144 and 100 sides, respectively, in the high-risk cohort. The NPVs of magnetic resonance imaging, biopsy, and both for ipsilateral LNM were 98.3%, 98.5%, and 99.1%, respectively, in the overall cohort, and 95.8%, 97.1%, and 97.6%, respectively, in the high-risk cohort.Unilateral LND may be indicated based on side-specific LNM risk as assessed by prebiopsy multiparametric magnetic resonance imaging and biopsy.

Background/Aim: Several prognostic risk factors have been recognized when using cisplatin-based conventional chemotherapy for the treatment of advanced urothelial carcinoma (UC); these include performance status (PS), liver metastasis, hemoglobin (Hb) levels, time from prior chemotherapy (TFPC), and other systemic inflammation scores including neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). However, the benefit of these indicators for predicting outcome of immune checkpoint inhibitors is not fully understood. Here, we investigated the predictive value of the indicators in patients who received pembrolizumab for the treatment of advanced UC. Patients and Methods: Seventy-five patients who received pembrolizumab treatment for advanced UC were included. The Karnofsky PS, liver metastasis, hemoglobin levels, TFPC, NLR, and PLR were analyzed, and their relationship with overall survival (OS) was determined. Results: All factors were highlighted as significant prognostic indicators for OS in the univariate proportional regression analysis (p

Background Focal Therapy (FT) for Prostate Cancer (PCa) is promising. However, long-term oncological results are awaited and there is no consensus on follow-up strategies. Molecular biomarkers (MB) may be useful in selecting, treating and following up men undergoing FT, though there is limited evidence in this field to guide practice. We aimed to conduct a consensus meeting, endorsed by the Focal Therapy Society, amongst a large group of experts, to understand the potential utility of MB in FT for localised PCa. Materials and methods A 38-item questionnaire was built following a literature search. The authors then performed three rounds of a Delphi Consensus using DelphiManager, using the GRADE grid scoring system, followed by a face-to-face expert meeting. Three areas of interest were identified and covered concerning MB for FT, i) the current/present role; ii) the potential/future role; iii) the recommended features for future studies. Consensus was defined using a 70% agreement threshold. Results Of 95 invited experts, 42 (44.2%) completed the three Delphi rounds. Twenty-four items reached a consensus and they were then approved at the meeting involving (n=15) experts. Fourteen items reached a consensus on uncertainty, or they did not reach a consensus. They were re-discussed, resulting in a consensus (n=3), a consensus on a partial agreement (n=1), and a consensus on uncertainty (n=10). A final list of statements were derived from the approved and discussed items, with the addition of three generated statements, to provide guidance regarding MB in the context of FT for localised PCa. Research efforts in this field should be considered a priority. Conclusions The present study detailed an initial consensus on the use of MB in FT for PCa. This is until evidence becomes available on the subject.

ObjectiveTo compare renal function (RF) outcomes after bladder-preserving tetramodal therapy against muscle-invasive bladder cancer (MIBC) to those after radical cystectomy (RC).MethodsThis study included 95 patients treated with tetramodal therapy consisting of transurethral bladder tumour resection, chemoradiotherapy and partial cystectomy (PC) and 300 patients treated with RC. The annual change in the estimated glomerular filtration rate (eGFR) was compared using the linear mixed model. Renal impairment was defined as a >25% decrease from the pretreatment eGFR, and renal impairment-free survival (RIFS) was calculated. The association between treatment type and renal impairment was assessed.ResultsThe number of patients who received neoadjuvant chemotherapy was 8 (8.4%) in the tetramodal therapy group and 75 (25.0%) in the RC group. After the inverse probability of treatment weighting adjustments, the baseline characteristics were balanced between the treatment groups. The mean eGFR before treatment in tetramodal therapy and RC groups was 69.4 and 69.6 mL/min/1.73 m2 and declined with a slope of −0.7 and −1.5 mL/min/1.73 m2/year, respectively. The annual deterioration rate of post-treatment eGFR in the tetramodal therapy group was milder than in the RC group. The 5-year RIFS rate in the tetramodal therapy and the RC groups was 91.2 and 85.2%, respectively. Tetramodal therapy was an independent factor of better RIFS compared with RC.ConclusionsRF was better preserved after tetramodal therapy than after radical therapy; however, even after tetramodal therapy, the eGFR decreased, and a non-negligible proportion of patients developed renal impairment.

The purpose of this study was to evaluate the impact of progressive site-directed therapy (PSDT) for oligometastatic castration-resistant prostate cancer (OM-CRPC) on the efficacy of subsequent androgen receptor axis-targeted (ARAT) drugs, and to demonstrate the possibility of prolonging overall survival (OS). We performed a retrospective analysis of 15 OM-CRPC patients who underwent PSDT and subsequently received first-line ARAT drugs (PSDT group) and 13 OM-CRPC patients who were treated with first-line ARAT drugs without PSDT (non-PSDT group). PSDT was performed with the intention of treating all progressing sites detected by whole-body diffusion-weighted MRI with radiotherapy. Thirteen patients (86.7%) treated with PSDT had a decrease in PSA levels, which was at least 50% in 10 (66.7%) patients. The median PSA progression-free survival (PFS) for PSDT was 7.4 months. The median PSA-PFS for ARAT was 27.2 months in patients in the PSDT group and 11.7 months in the non-PSDT group, with a significant difference between the two groups (hazard ratio [HR], 0.28; p = 0.010). The median OS was not reached in the PSDT group and was significantly longer than 44.5 months in the non-PSDT group (HR, 0.11; p = 0.014). In OM-CRPC, PSDT may improve the efficacy of subsequent ARAT and OS.

To report experience with focal brachytherapy (FB) and compare its clinical outcomes with those of radical prostatectomy (RP) in localized prostate cancer.Fifty-one patients with low- to intermediate-risk prostate cancer underwent low-dose-rate FB. Survival rates free from biochemical failure (BF), additional treatment (AT) including re-FB, and whole-gland or systemic salvage therapy (ST) were calculated and oncological risk factors were investigated. Patient-reported outcomes on genitourinary function were also assessed. Using propensity scoring, 51 pair-matched RP patients were selected. Oncological control, urinary continence, and ejaculation status after FB and RP were compared.During a median 5.7-year follow-up, BF, AT, and ST occurred in 12 (24%), 10 (20%), and 4 FB patients (8%), respectively. 6 of 10 AT patients were managed with re-FB alone. In the RP cohort, 3 patients (6%) underwent ST. 5-year BF-free survival rate after FB was 79%. Compared to 5-year ST-free survival rate of 94% after RP, ST-free and AT-free survival rates after FB were 93% (P = 0.813) and 87% (P = 0.049), respectively. Multivariate analyses of FB-treated patients showed that time to PSA nadir was negatively associated with BF and AT (hazard ratio 0.84 and 0.83, respectively, P0.001 for each). The difference in oncological outcomes between low- and intermediate-risk categories was not significant. At 2 years after FB and RP, pad-free continence rates were 100% and 81%, respectively (P = 0.001). Ejaculation was preserved in 67% and 0% of patients who had been capable of ejaculation at baseline, respectively (P0.001).In low- to intermediate-risk prostate cancer, FB-treated patients achieved superior genitourinary function compared to pair-matched RP patients. The need for ST was not substantially different between the 2 treatment cohorts. Over half of patients requiring AT could be managed by re-focal treatment rather than whole-gland ST. Early PSA nadir may predict poor oncological control after FB.
