Nivolumab

OBJECTIVE: Nivolumab plus ipilimumab is a recommended first-line therapy regimen for metastatic renal cell carcinoma. However, it is not clear which patient characteristics are associated with its effectiveness. METHODS: We retrospectively examined 67 metastatic renal cell carcinoma patients treated with nivolumab plus ipilimumab as a first-line therapy in multiple institutions from September 2018 to August 2022. We analyzed the relationships between survival outcomes and patient-related variables, including paraneoplastic symptoms...

Merkel cell carcinoma (MCC) is a rare skin cancer characterized by neuroendocrine differentiation. Its carcinogenesis is based either on the integration of the Merkel cell polyomavirus or on ultraviolet (UV) mutagenesis, both of which lead to high immunogenicity either through the expression of viral proteins or neoantigens. Despite this immunogenicity resulting from viral or UV-associated carcinogenesis, it exhibits highly aggressive behavior. However, owing to the rarity of MCC and the lack of epidemiologic registries with detailed clinical data, there is some uncertainty regarding the spontaneous course of the disease...

BACKGROUND: We evaluated the concordance/discordance of PD-L1 staining results between the 28-8 and 22C3 assays and its impact on the efficacy outcomes of advanced gastric cancer patients treated with nivolumab plus chemotherapy. METHODS: This retrospective study involved 143 gastric cancer patients treated with first-line nivolumab plus chemotherapy whose PD-L1 results with both 28-8 and 22C3 assays were available. The concordance/discordance between these assays and the inter-observer variability were evaluated for PD-L1 combined positive score (CPS) positivity...

Clear cell carcinoma is a rare and very aggressive subset of cervical cancer, with poor outcome if diagnosed at advanced stage. There are few data available on the optimal management of this histotype, and treatment recommendations that include surgery and chemoradiotherapy, are essentially based on those for squamous cell carcinoma. Here we report the case of a young patient newly diagnosed with advanced stage (FIGO IIB) clear cell carcinoma of the uterine cervix who received a window of opportunity one injection of nivolumab followed by standard chemoradiotherapy...

A 77-year-old man presented to our hospital with a chief complaint of stomachache. He received a diagnosis of unresectable advanced gastric cancer classified as cT3, N+, M1(LYM, HEP, OSS), Stage ⅣB. He underwent first-line chemotherapy with SOX, second-line treatment with PTX plus Ram, and third-line treatment with nivolumab. The primary tumor showed a reduction in size, and liver and lymph node metastases were not detectable. However, after 5 years of chemotherapy, a re- enlargement was observed in the primary gastric lesion without progression of liver and lymph node metastases...

A 66-year-old male came to our hospital because of occult blood in stool and anemia. The patient was diagnosed as unresectable advanced gastric cancer,( ML/Less, type 2, tub2, cT4b[liver], cN+, cM0, cStage Ⅳ, HER2 negative). He was given oxaliplatin plus S-1 therapy. In the 3rd course of chemotherapy, he had severe anemia, and active bleeding from the tumor. To control the bleeding he underwent distal gastrectomy, lateral segmentectomy of the liver, and S4 partial hepatectomy. The patient underwent adjuvant chemotherapy with docetaxel plus S-1...

A 68-year-old male patient underwent laparoscopic pyloric gastrectomy(D2)in October 2015 for gastric cancer, pStage ⅠB. In August 2017, a 3 cm large abdominal wall metastasis in the left lateral abdomen was removed. In September 2019, a 2 cm tumor was found in the left inguinal region. The left inguinal area was repaired using mesh with the TAPP technique because of a large abdominal wall defect centered on the inner inguinal ring. Three and a half years after the resection, he is continuing complete response(CR)with nivolumab therapy...

The patient was a 54-year-old male at the time of initial examination. He was aware of numbness and weakness in the left hemisphere of his body and came to see the hospital. He was diagnosed with brain metastasis of lung cancer and started treatment(cT2N0M1[Brain]). He underwent gamma knife for the head lesion and nivolumab for the lung lesion. The patient's lesions shrank with the success of the medical treatment, but recurred with small intestinal metastasis. He underwent a partial resection of the small intestine and was treated again with nivolumab, which resulted in a complete response...

The use of nivolumab as first-line therapy for unresectable advanced gastric cancer has now become a standard practice, and its efficacy has been established. This is the first report of a patient with advanced gastric cancer who underwent conversion surgery after first-line nivolumab combination chemotherapy. The patient was a 58-year-old woman. Her medical history included hypertension and dyslipidemia. She had advanced gastric cancer with extensive lymph node metastasis in the left supraclavicular fossa and around the abdominal aorta...

BACKGROUND: Nivolumab plus cabozantinib (NIVO + CABO) was approved for first-line treatment of advanced renal cell carcinoma (aRCC) based on superiority versus sunitinib (SUN) in the phase III CheckMate 9ER trial (18.1 months median survival follow-up per database lock date); efficacy benefit was maintained with an extended 32.9 months of median survival follow-up. We report updated efficacy and safety after 44.0 months of median survival follow-up in intent-to-treat (ITT) patients and additional subgroup analyses, including outcomes by International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) prognostic risk score...

BACKGROUND: The CheckMate274 trial has reported enhanced disease-free survival rates in patients with stage pT3-4/ypT2-4 or pN+ urothelial carcinoma (UC) undergoing adjuvant nivolumab therapy. This study compares prognostic differences between urothelial carcinoma of the bladder (UCB) and upper tract urothelial carcinoma (UTUC). METHODS: We retrospectively analyzed data from 719 patients with UC who underwent radical surgery, stratifying to patients at stage pT3-4 and/or pN+ without neoadjuvant chemotherapy (NAC) or at ypT2-4 and/or ypN+ with NAC (potential candidates for adjuvant immunotherapy), and to those who were not candidates for adjuvant immunotherapy...

Pseudoprogression encapsulates a process of temporary radiographic growth followed by subsequent regression of metastatic melanoma lesions in response to immune checkpoint blockade (ICB), such as the combination of anti-programmed cell death protein 1 (PD-1) and anticytotoxic T-lymphocyte-associated antigen 4 therapy. This occurs in approximately 5-10% of ICB-treated patients, but has not yet been described in the context of novel combination therapies. Here, we report a case of an 89-year-old patient with metastatic melanoma to the liver, lung and lymph nodes, who underwent treatment with Opdualag (combining anti-PD-1 nivolumab and anti-lymphocyte-activation gene 3 relatlimab ICBs), and developed pseudoprogression after two cycles of therapy...

BACKGROUND: Given its heterogeneity and diverse clinical outcomes, precise subclassification of BCLC-C hepatocellular carcinoma (HCC) is required for appropriately determining patient prognosis and selecting treatment. METHODS: We recruited 2,626 patients with BCLC-C stage HCC from multiple centers, comprising training/test (n=1,693) and validation cohorts (n=933). The XGBoost was chosen for maximum performance among the machine learning (ML) models. Patients were categorized into low-/intermediate-/high-/very high-risk subgroups which were based on the estimated prognosis, and this subclassification was named the CLAssification via Machine learning of BCLC-C (CLAM-C)...

Many studies have focused on the prognostic role of soluble programmed death ligand 1 (sPD-L1) in non-small cell lung cancer (NSCLC), but outcomes are ambiguous and further investigations are needed. We addressed the matter by studying sPD-L1 in baseline samples and in longitudinal samples taken prior to three subsequent cycles of anti-PD-1/anti-PD-L1 treatments. Eighty patients with NSCLC were enrolled. Median sPD-L1 level at baseline was 52 pg/mL [95% confidence interval (CI) 49-57]. In patients treated with pembrolizumab and nivolumab, the concentration of sPD-L1 remained rather stable throughout treatment...

BACKGROUND: In Japan, preoperative adjuvant chemotherapy followed by surgical resection is the standard treatment for patients with locally advanced esophageal squamous cell carcinoma. However, the risk of recurrence after surgical resection remains high. Although a randomized controlled trial evaluating the efficacy of nivolumab, a fully human monoclonal anti-programmed death 1 antibody, as postoperative adjuvant therapy after neoadjuvant chemoradiotherapy and surgery established its superior efficacy as adjuvant therapy, the efficacy for patients who received preoperative adjuvant chemotherapy has not been demonstrated...

Leiomyomatosis and renal cell carcinoma (HLRCC) are rare autosomal dominant cancer syndromes characterized by cutaneous leiomyoma, uterine leiomyoma, and renal cell carcinoma (RCC). RCC in HLRCC is an aggressive metastatic tumor that develops at a young age. Here, we report the case of a patient with HLRCC who was diagnosed after the spontaneous rupture of a renal tumor. The patient underwent cytoreductive surgery, followed by combination therapy with the immune checkpoint inhibitor (ICI) nivolumab and cabozantinib, a tyrosine kinase inhibitor (TKI); however, no improvements were achieved...

BACKGROUND: No head-to-head clinical trials have compared the differences in adverse events (AEs) between nivolumab plus ipilimumab (NIVO-IPI) and nivolumab plus cabozantinib (NIVO-CABO) in the treatment of metastatic renal cell carcinoma (mRCC). AIM: We analysed the two largest real-world databases, the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) and the World Health Organization's VigiBase, to elucidate the differences in AEs between NIVO-IPI and NIVO-CABO...

A 75-year-old woman with stage IVB (cT2bN3M1b) lung adenocarcinoma was administered nivolumab, ipilimumab, carboplatin, and paclitaxel. Fourteen days after receiving chemotherapy, she experienced an impaired consciousness and a cerebrospinal fluid analysis revealed high protein levels and pleocytosis. She was diagnosed with nivolumab- and ipilimumab-induced encephalitis and was treated with corticosteroids which were tapered to 10 mg/day, with no symptom recurrence. She died 18 weeks after the initial presentation, as the cancer worsened...

Anti-pituitary-specific transcription factor-1 (PIT-1) hypophysitis, a paraneoplastic syndrome resulting from an autoimmune response against PIT-1, typically manifests with undetectable levels of growth hormone (GH) and prolactin (PRL), and significantly low levels of serum thyroid-stimulating hormone (TSH) at diagnosis. These hormonal levels are highly specific to this disease and serve as key diagnostic indicators. Herein, we present a detailed clinical course of a 69-year-old male with a history of gastric cancer and lymph node metastases who developed anti-PIT-1 hypophysitis after the initiation of immune checkpoint inhibitor (ICI) therapy, specifically nivolumab, oxaliplatin, and capecitabine...
