PURPOSE: Programmed death 1 (PD-1) pathway inhibitors have not been prospectively evaluated in patients with non–clear cell renal cell carcinoma (nccRCC). The phase II KEYNOTE-427 study (cohort B) was conducted to assess the efficacy and safety of single-agent pembrolizumab, a PD-1 inhibitor, in advanced nccRCC. METHODS: Patients with histologically confirmed, measurable (Response Evaluation Criteria in Solid Tumors [RECIST] version 1.1) nccRCC and no prior systemic therapy received pembrolizumab 200 mg intravenously once every 3 weeks for ≤ 24 months. The primary end point was objective response rate (ORR) per RECIST v1.1. RESULTS: Among enrolled patients (N = 165), 71.5% had confirmed papillary, 12.7% had chromophobe, and 15.8% had unclassified RCC histology. Most patients (67.9%) had intermediate or poor International Metastatic RCC Database Consortium risk status and tumors with programmed death ligand 1 (PD-L1) combined positive score (CPS) ≥ 1 (61.8%). The median time from enrollment to database cutoff was 31.5 months (range, 22.7-38.8). In all patients, the ORR was 26.7%. The median duration of response was 29.0 months; 59.7% of responses lasted ≥ 12 months. The ORR by CPS ≥ 1 and CPS < 1 status was 35.3% and 12.1%, respectively. The ORR by histology was 28.8% for papillary, 9.5% for chromophobe, and 30.8% for unclassified. Overall, the median progression-free survival was 4.2 months (95% CI, 2.9 to 5.6); the 24-month rate was 18.6%. The median overall survival was 28.9 months (95% CI, 24.3 months to not reached); the 24-month rate was 58.4%. Overall, 69.7% of patients reported treatment-related adverse events, most commonly pruritus (20.0%) and hypothyroidism (14.5%). Two deaths were treatment related (pneumonitis and cardiac arrest). CONCLUSION: First-line pembrolizumab monotherapy showed promising antitumor activity in nccRCC. The safety profile was similar to that observed in other tumor types.

On 24th of February 2022, Ukrainian cancer patients had to face a new war. Here we describe an experience of the Maria Sklodowska-Curie National Research Institute of Oncology Branch Krakow in providing cancer care for Ukrainian refugees during the initial 6 weeks of war. We present patients' characteristic, point out the main challenges and share initiatives undertaken. For this cross-sectional analysis, we have gathered demographic and clinical data together with date of crossing the Polish-Ukrainian border for 112 Ukrainian refugees with cancer who had their first-time oncology consultation between 24th February and 8th April 2022. We have also implemented national guidelines and created local procedures, interventions and policies to manage this situation. The peak of patient inflow was the third week of War and refugees accounted for 13% of all first-time patients within that period of time. The majority of refugees were women (86%), treated radically (57%) with breast cancer (43%). Most of the patients required systemic treatment (67%). Amongst the main challenges at the time were differences in the reimbursement system, communication issues, lack of patients' documentation or tissue samples, prolonged diagnostic or treatment interruptions, increased risk of COVID-19 infections, chemotherapy side effects, and lack of procedures. Legal, procedural and organizational steps implemented at the local and national level were described. The Russian invasion on Ukraine forced an unexpectedly high number of Ukrainian cancer patients to seek help abroad, leading to the straining of the health care system in Poland.

Aim of the study: The incidence of melanoma is increasing rapidly worldwide. Metastatic melanoma is still an incurable disease, although an era of new drugs is approaching. Current methods to predict outcomes in patients with advanced, metastatic melanoma are limited. A retrospective analysis...

The standard therapy for hormone-receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer includes the use of cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) with endocrine therapy. The optimal post-CDK4/6i treatment sequence is unclear. This cohort study evaluated the initiation, characteristics, and outcomes of chemotherapy following CDK4/6i-based treatment. Among the 227 patients who began CDK4/6i therapy, 114 completed it. Seventy-nine female patients received further treatment, including 55 receiving chemotherapy. The average age was 60.1 years. Post-CDK4/6i chemotherapy was typically (69.1%) first-line due to an impending visceral crisis. The median progression-free survival (mPFS) was 3.0 months (range 0.5–18.9), and the median overall survival (mOS) was 8.3 months (0.5–26.1). The median OS from the end of CDK4/6i treatment was 12.4 months (1.5–26.8). In univariate analysis, neither mPFS nor mOS was associated with age, tumor grade, receptor status, Ki67 status, time from diagnosis to CDK4/6i cessation, therapy line, or CDK4/6i type. Dose reduction occurred in 12 patients (21.8%), and chemotherapy was ceased due to adverse events in 8 patients (14.6%). Chemotherapy showed limited benefit regardless of the regimen. The role of chemotherapy may evolve with broader CDK4/6i use in adjuvant treatment.

Background: Palliative care must be tailored for patients with extended disease trajectories, such as those with hormone receptor-positive, Human Epidermal Growth Factor Receptor 2 (HER2)-negative advanced breast cancer (ABC), including the appropriate timing of discontinuing treatment. This study aimed to assess the interval between the last oncologist visit and death and the application of systemic treatment near the end of life in this patient population. Methods: This retrospective study included patients with luminal ABC who received at least two lines of palliative systemic treatment at the National Research Institute of Oncology in Poland, and died between November 2020 and March 2024. Results: Seventy-six women, with a median age 62.8 years (range: 35.3–91.5), were included. The median number of prior palliative systemic treatment lines was three (range: 2–6). At their last recorded oncologist visit, 75% of the patients were receiving active treatment (53% with hormonal therapy and 22% with chemotherapy). Only 25% were under continuous palliative care at this visit. Treatment was administered within the last month of life to 53% of the patients. The median duration from the last oncologist visit to death was 23 days (range: 0–408). The duration of this time interval was only associated with the performance status at the last visit (p < 0.05). Conclusions: Oncologists frequently delay the recognition of the need to discontinue systemic therapy. Patients with luminal HER2-negative ABC may be offered numerous effective lines of systemic treatment, complicating this decision further. Implementing clearer guidelines for end-of-life care for this group and providing proper training for healthcare providers is essential.
