Clinical characteristics and mortality in all Czech patients after pacemaker implantation in the last decade.

Background and aims: Analysis of mortality from the national health registries and data from a specific central registry dealing with the implantation of pacemakers (REPACE) in Czech patients. Methods and results: Retrospective observational analysis of pacemakers' implantation in all Czech patients [n = 82,791; 47,070 (56.9%) men, 75.9 ± 10.4 years old] between 2010 and 2021. Almost 114,000 pacemakers were implanted between 2010 and 2021, of which 27.9% were single-chamber, 67.4% were dual-chamber and 4.6% were biventricular. The annual number of implantations has been steadily increasing with a 6% annual decline in 2020 with increased mortality and reductions in care provided, likely related to COVID-19. The observed 5-year relative survival was 88.6% (overall survival 60.6%) and the 10-year relative survival was 75.9% (overall survival 32.7%). Causes of death 5ary according to the age of the patient. The highest difference 1n the reported numbers in the REPACE Registry did not exceed 2% in comparison with the National Register of Reimbursed Health Services. Conclusion: This study followed all Czech patients with pacemaker's implantation in between 2010 and 2021. The annual number of 1mplantations has been steadily 1ncreasing. Patients with implanted pacemakers had a significantly higher mortality than the average population. Number of patients in the registry corresponded almost perfectly with the National Register of Reimbursed Health Services.

Can Previous Chemotherapy Affect the Outcome of Nivolumab Treatment in Non-small Cell Lung Cancer?

AIM: This study compared the results of nivolumab treatment in patients with pulmonary adenocarcinomas based upon previous chemotherapeutic regimens. PATIENTS AND METHODS: The data source for this retrospective study was the Czech VILP registry of patients with nivolumab-treated adenocarcinomas in second and higher lines of treatment. In relation to objective response rate, progression-free interval, and overall survival, three comparisons of patient were made: A: Those treated in first line with cisplatin and pemetrexed versus carboplatin with paclitaxel or vinorelbine; B: treatment with cisplatin and pemetrexed versus carboplatin with paclitaxel/vinorelbine and bevacizumab; and C: treatment in previous lines with pemetrexed (first-line cisplatin and pemetrexed plus those treated in second line with pemetrexed) versus treatment with taxane (first-line carboplatin and paclitaxel only plus those treated with second-line docetaxel). RESULTS: We observed no differences in objective response rate or progression-free survival between patients treated with the stated chemotherapeutic regimens. We observed a trend towards better overall survival for patients treated with carboplatin plus taxanes or vinorelbine with/without bevacizumab. CONCLUSION: From our overall survival data, a chemotherapeutic regimen of carboplatin plus taxanes or vinorelbine with/without bevacizumab might be a better partner for immunotherapy than a cisplatin and pemetrexed-based one.

Locally advanced breast cancer in elderly patients.

BACKGROUND: Although locally advanced breast cancer (LABC) is more common in the elderly population, there is little data on the clinical characteristics and survival of these patients. The aim of the present study was to compare different factors affecting survival in elderly patients with LABC. METHODS: Retrospective analysis was carried out on a cohort of 80 patients aged 70 to 96 years, diagnosed with LABC defined as T3 N1, T4 N0, any N2 or N3, and M0. The prognostic impact of selected clinical parameters including age, comorbidities, tumour grade, HER2 status, tumour stage, local therapies, and systemic treatments was studied. RESULTS: The median age of the patients was 79 years. The majority (n=53; 66%) had at least one significant comorbidity according to the Charlson score evaluation. The median overall survival was 50.6 months. As expected, hormonal therapy was the dominant mode of systemic treatment, but 24% also received at least one line of chemotherapy. Local therapies including surgery and/or radiotherapy were applied in 58% of patients. CONCLUSIONS: The diagnosis of LABC in the elderly is associated with poor prognosis. Age and serious comorbidities were negative prognostic factors.

Soft-tissue extramedullary multiple myeloma prognosis is significantly worse in comparison to bone-related extramedullary relapse.

Even in the era of new drugs, multiple myeloma patients with extramedullary relapse have a poor prognosis. Our goal was to analyze the frequency and outcome of extramedullary relapse occurring in relapsed multiple myeloma patients. In total, we analyzed the prognosis of 226 relapsed multiple myeloma patients treated between 2005 and 2008 and evaluated them for presence of extramedullary relapse. We found evidence of extramedullary relapse in 24% (55 of 226) of relapsed multiple myeloma patients. In 14% (32 of 226) of patients, the lesions were not adjacent to the bone, while extramedullary relapse adjacent to the bone was documented in 10% (23 of 226) of cases. Patients without extramedullary relapse had significantly longer overall survival than patients with extramedullary relapse (109 vs. 38 months; P<0.001). Moreover, patients with soft tissue-related extramedullary relapse had significantly poorer overall survival compared to bone-related extramedullary relapse patients (30 vs. 45 months; P=0.022). Also, overall survival from diagnosis was as low as five months for soft tissue-related extramedullary relapse patients when compared to 12 months overall survival for bone-related extramedullary relapse. This is the first study that shows a significant difference in prognosis for different types of extramedullary relapse. If the extramedullary myeloma infiltration was not bone-related, overall survival after relapse was extremely short (5 months).
