Chronic myeloid leukemia is associated with a BCR/ABL oncoprotein inhibited by imatinib mesylate, the first tyrosine kinase inhibitor. Although experimental studies have clearly demonstrated the efficacy of imatinib, up-to-date data on its effectiveness at the population level are limited. Our study aims to assess the change in disease-specific survival for chronic myeloid leukemia after introducing tyrosine kinase inhibitors in first-line treatment. This study analyzed data from two population-based cancer registries in Italy. Disease-specific survival for chronic myeloid leukemia cases diagnosed before and after the introduction of tyrosine kinase inhibitors (February 2002) were calculated up to 10 years. Hazard ratios were calculated using Cox regression models adjusted for sex, age at diagnosis and residency. An interrupted time series analysis was also performed. Between 1996 and 2012, 357 new cases of chronic myeloid leukemia were diagnosed (standardized incidence rate of 1.2 per 100,000 residents), quite constant throughout the period. The interrupted time series analysis showed a gain of 40.4% in 5 years of disease-specific survival for chronic myeloid leukemia (from 47.3, 95%CI 38.5–55.5% to 80.8%, 95%CI 74.5–85.8%) after the introduction of tyrosine kinase inhibitors. The hazard ratio was 0.36 (95%CI 0.25–0.52) for cases diagnosed after tyrosine kinase inhibitor introduction, with differences per age at diagnosis: 74yo 0.41 (95%CI 0.23–0.73). An improvement in survival (hazard ratio 0.66, 95%CI 0.36–1.20) was also observed in cases diagnosed before, and alive at, tyrosine kinase inhibitors introduction. Tyrosine kinase inhibitors increased disease-specific survival both for new and prevalent chronic myeloid leukemia cases. The effectiveness was similar to that observed in trials only in patients ages 65 years or younger.
The COVID-19 pandemic has caused delays in cancer diagnoses and reductions in treatments. The aim of this work is to evaluate the impact of the pandemic on prostate cancer by evaluating whether there has been a shift towards more aggressive (Gleason) and more advanced tumors (stage IV) and a decline in treatments. The study was conducted on 1123 cases of prostate cancer incident in the Province of Reggio Emilia, Northern Italy, in the period of 2018–2021. In 2020, there was a decline in new diagnoses of prostate cancer (−31%), followed by a slight recovery in 2021 (+5%). While Gleason 7 and 8–10 values remained constant, a significant decrease was recorded in stage I (38.7%, 41.6%, 35.5%, and 27.7%) and an increase in stage IV (13.1%, 13%, 15.4%, and 20%) cases in the years 2018, 2019, 2020, and 2021, respectively. However, there was no impact on surgical treatment (which remained constant at around 35%) and radiotherapy (around 39%). Our findings underline the profound impact of COVID-19 on prostate cancer management, highlighting the importance of healthcare resilience in the face of unprecedented disruptions.

Introduction Haematological malignancies often escape the standard information flows of cancer registries because diagnosis is not always based on bone marrow histology but, rather, on other laboratory tests. Objective To quantify incident haematological malignancies identified exclusively through the laboratory information system and to measure the impact of that source on the sensitivity and accuracy of registering these malignancies. Methods We collected data from the only provincial laboratory of Reggio Emilia on molecular biology, flow cytometry tests and bone marrow smears to detect specific markers of some chronic haematological malignancies. We carried out a record linkage between laboratory reports (period 2013-2017) of patients resident in the province of Reggio Emilia and the Cancer Registry of Reggio Emilia. Results Of the 303 patients who underwent at least one of these tests, 85 were not included in our Cancer Registry. Of these 85 patients, 42 had received a diagnosis of cancer: 34 myeloproliferative neoplasms, 3 chronic myeloid leukaemias, 3 myelodysplastic neoplasms, 1 multiple myeloma and 1 chronic lymphocytic leukaemia. We recovered 4.2% of the total number of chronic haemolymphopoietic cancers registered in the study period, accounting for 15% of myeloproliferative neoplasms. For 30% of prelinkage cases, the specificity of the morphological code improved. Conclusions Although the laboratory information system's contribution to the completeness of Cancer Registry incident cases was modest, it is useful to add laboratory data to routine cancer registry information flows due to the increasing use of molecular characterisation and to the phenomenon of dehospitalisation.
International studies have shown an increase in cancer incidence among young adults, raising public concern. This study aims examines trends in the cancer incidence among individuals aged 15–49 years in a province of Northern Italy, covering diagnoses from 1996 to 2021, and compares the annual percentage change (APC) with national and international data. In males, the overall cancer incidence showed a modest increase between 1996 and 2013 (APC 1.6), followed by a decline in the subsequent years (APC −2.5). In females, there was a modest increase over the entire period (APC 1.0). The lung cancer incidence decreased in both sexes (APC −3.9 in males and APC −3.3 in females), while a decrease was observed for colorectal cancers in women (APC −2.4). Since 2015, the thyroid cancer incidence declined significantly in females (APC −10.2), while an increase was noted in males (APC 2.5). The testicular cancer incidence rose in males (APC 1.5), and the melanoma incidence increased in both sexes (APC 3.4 in males and APC 3.9 in females). The breast cancer incidence remained stable (APC 0.3). These results underline the importance of promoting healthy lifestyles even among younger generations to address emerging cancer trends and support cancer prevention efforts.
