RESUMO
BACKGROUND: Nivolumab plus ipilimumab (NIVO + IPI) is the first-line treatment for patients with metastatic renal cell carcinoma (mRCC). While approximately 40% of patients treated with NIVO + IPI achieve a durable response, 20% develop primary resistance with severe consequences. Therefore, there is a clinical need for criteria to select patients suitable for NIVO + IPI therapy to optimize its therapeutic efficacy. Accordingly, our aim was to evaluate the association between candidate biomarkers measured before treatment initiation and survival. METHODS: This was a multi-institutional, retrospective, cohort study of 183 patients with mRCC treated with systematic therapies between August 2015 and July 2023. Of these, 112 received NIVO + IPI as first-line therapy: mean age, 68 years; men, 83.0% (n = 93), and clear cell histology, 80.4% (n = 90). Univariable and multivariable analyses were used to evaluate associations between biomarkers and survival. RESULTS: On univariate analysis, high C-reactive protein and systemic index, a high neutrophil-to-lymphocyte and platelet-to-lymphocyte ratio, and a low lymphocyte-to-monocyte ratio (LMR) were associated with shorter overall survival (OS). On multivariable analysis, a LMR ≤ 3 was retained as an independent factor associated to shorter OS with the highest accuracy (C-index, 0.656; hazard ratio, 7.042; 95% confidence interval, 2.0-25.0; p = 0.002). CONCLUSION: A low LMR may identify patients who would be candidate for NIVO + IPI therapy for mRCC.

BACKGROUND: Although nivolumab plus ipilimumab is the standard treatment for metastatic renal cell carcinoma (RCC), its efficacy and safety in older patients remain unclear. Therefore, this study aimed to assess the clinical outcomes of nivolumab plus ipilimumab for metastatic RCC in patients aged ≥ 75 years. METHODS: We enrolled 120 patients with metastatic RCC treated with nivolumab plus ipilimumab from August 2015 to January 2023. Objective response rates (ORRs) were compared between patients aged < 75 and ≥ 75 years. Progression-free survival (PFS), overall survival (OS), and adverse events were compared between the groups. Adverse events were evaluated according to the Response Evaluation Criteria in Solid Tumors 1.1. RESULTS: Among the patients, 57 and 63 were classified as intermediate and poor risk, respectively, and one could not be classified. The median follow-up duration after the initiation of treatment was 16 months. The patient characteristics between the groups, except for age, were not significantly different. Intergroup differences in ORR (42% vs. 40%; p = 0.818), PFS (HR: 0.820, 95% CI 0.455-1.479; p = 0.510), and median OS (HR: 1.492, 95% CI 0.737-3.020; p = 0.267) were not significant. The incidence of adverse events (50% vs. 67%; p = 0.111) and nivolumab plus ipilimumab discontinuation due to adverse events was not significantly different between the groups (14% vs. 13%; p = 0.877). CONCLUSIONS: The effectiveness of nivolumab plus ipilimumab was comparable between patients with metastatic RCC aged < 75 and those ≥ 75 years with respect to their ORRs, PFS, OS, and adverse event rates.

A 46-year-old woman was referred to our hospital with a left-sided renal tumor pointed out by ultrasonography at the time of a medical checkupï¼Computed tomography revealed a mass measuring 88×77×68 mm on the upper pole of the left kidney. She was diagnosed with cT2aN0M0 clear cell renal cell carcinoma. Laparoscopic left nephrectomy was performed uneventfully. Histopathological diagnosis was clear cell renal cell carcinoma, G2, v1, pT2. Four months after surgery, lung metastases appeared, and systemic therapy was given sequentially as follows ; sunitinib for 2 months, nivolumab for 8 months, axitinib for 17 months, and pazopanib for 2 monthsï¼However, metastases progressed, and a re-administration of nivolumab was planned. The nivolumab re-treatment resulted in a marked reduction in multiple lung metastases despite the previous failure by nivolumab treatment. There are few reports on the therapeutic effect of re-administration of nivolumab. We report a case of successful treatment by re-administration of nivolumab.

BACKGROUND: We report a case of diffuse large B-cell lymphoma that progressed rapidly after androgen deprivation therapy for prostate cancer in a patient with a history of IgG4-related disease. Estrogen has been reported to be a possible cause of acute exacerbations of malignant lymphoma only in mouse models. Therefore, its clinical significance has not been clarified. CASE PRESENTATION: This case report describes a 75-year-old man with prostate cancer who had IgG4-related disease. Hormone therapy was initiated to treat prostate cancer, but he developed dyspnea and back pain. A diagnosis was made of diffuse large B-cell lymphoma. Immunohistochemistry was positive for estrogen receptor ß, which led us to suspect rapid progression of diffuse large B-cell lymphoma due to estrogen suppression by gonadotropin-releasing hormone antagonists. Hormone therapy was discontinued, and the patient received R-CHOP therapy. Subsequently, the lymphoma masses shrunk, and the patient obtained remission. CONCLUSION: This case is the first report of clinical significance regarding the crucial role of estrogen and estrogen receptor ß in malignant lymphoma in a patient with IgG4-related disease. Our report aims to raise awareness of the need to carefully select treatment options for prostate cancer patients with IgG4-related disease or lymphoma.

A recent approach to radiotherapy for prostate cancer is the administration of high doses of radiation to the prostate while minimizing the risk of side effects. Thus, image-guided radiotherapy utilizes advanced imaging techniques and is a feasible strategy for increasing the radiation dose. New radioactive particles are another approach to achieving high doses and safe procedures. Prostate brachytherapy is currently considered as a combination therapy. Spacers are useful to protect adjacent organs, specifically the rectum, from excessive radiation exposure.

BACKGROUND: Nivolumab plus ipilimumab (NIVO+IPI) is the first-line treatment for patients with metastatic renal cell carcinoma (mRCC). Approximately 40% of patients achieve a durable response; however, 20% develop primary resistant disease (PRD) to NIVO+IPI, about which little is known in patients with mRCC. Therefore, this investigation aimed to evaluate the clinical implication of PRD in patients with mRCC to select better candidates in whom NIVO+IPI can be initiated as first-line therapy. METHODS: This multi-institutional retrospective cohort study used data collected between August 2015 and January 2023. In total, 120 patients with mRCC treated with NIVO+IPI were eligible. Associations between immune-related adverse events and progression-free survival, overall survival (OS), and objective response rate were analyzed. The relationship between other clinical factors and outcomes was also evaluated. RESULTS: The median observation period was 16 months (interquartile range, 5-27). The median age at NIVO+IPI initiation was 68 years in the male-dominant population (n = 86, 71.7%), and most patients had clear cell histology (n = 104, 86.7%). PRD was recorded in 26 (23.4%) of 111 investigated patients during NIVO+IPI therapy. Patients who experienced PRD showed worse OS (hazard ratio: 4.525, 95% confidence interval [CI]: 2.315-8.850, p < 0.001). Multivariable analysis showed that lymph node metastasis (LNM) (odds ratio: 4.274, 95% CI: 1.075-16.949, p = 0.039) was an independent risk factor for PRD. CONCLUSIONS: PRD was strongly correlated with worse survival rates. LNM was independently associated with PRD in patients with mRCC receiving NIVO+IPI as first-line therapy and might indicate that a candidate will not benefit from NIVO+IPI.

Single nucleotide polymorphisms (SNPs) reportedly influence the effect of nivolumab in metastatic renal cell carcinoma (mRCC). This study aimed to evaluate the relationship between the clinical outcomes of patients with mRCC and SNPs in programmed cell death protein 1 (PD-1) protein-coding gene (PDCD1) and explore any potential correlation with patient prognosis and incidence of immune-related adverse events (irAEs). In total, 106 patients with mRCC, who were treated with nivolumab alone (n = 59) or nivolumab and ipilimumab (n = 47), were enrolled in the study. Three SNPs in the PDCD1 gene, namely PD-1.3, PD-1.5, and PD-1.6, were assessed. Patients harboring the PD-1.6 G allele experienced more severe (odds ratio, 3.390; 95% confidence interval 1.517-7.756; p = 0.003) and multiple (OR, 2.778; 95% CI, 1.020-6.993 p = 0.031) irAEs than those harboring the AA genotype. Thus, the existence of the PDCD1 PD-1.6 polymorphism (G allele) was associated with the occurrence of severe and multiple irAEs in patients with mRCC. Further evaluation of PDCD1 polymorphisms might help identify patients experiencing irAE by nivolumab treatment.

Readily available Boc-protected Z-alkenyl aminals could be used as Z-alkenyl and E-alkenyl imine precursors under acidic conditions. In the Mukaiyama-Mannich reaction of Z-alkenyl Boc-aminals, the E/Z geometry of the products was controlled by the catalyst used. The present method was also applied to asymmetric Mukaiyama-Mannich reactions.
