    IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced colorectal cancers at diagnosis. OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced oncologic stage and change in clinical presentation for patients with colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all 17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December 31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period), in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was 30 days from surgery. EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery, palliative procedures, and atypical or segmental resections. MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding, lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery, and palliative surgery. The independent association between the pandemic period and the outcomes was assessed using multivariate random-effects logistic regression, with hospital as the cluster variable. RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years) underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142 (56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR], 1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P < .001), and stenotic lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03). CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for these patients

    Molecular characterization of a large cohort of patients with Chronic Granulomatous Disease and identification of novel CYBB mutations: An Italian multicenter study

    Chronic Granulomatous Disease (CGD) is a rare inherited disorder in which phagocytes fail to produce antimicrobial superoxide because NADPH oxidase activity is absent. In about 65% of the cases, the disease is due to mutations affecting the X-linked CYBB gene, encoding the gp91(phox) subunit of NADPH oxidase. We investigated 34 CGD male patients by DHPLC and direct sequencing. A mutation was found in the CYBB gene of 33 patients and 9 of these were novel: one non-sense mutation (c.1123 G>T), three missense mutations (c.58G>A; c.1076 G>C; c.1357 T>A), two splice site mutations (c.141+5G>T; c.142-1G>A), one duplication (c.42-45dupCATT), one deletion (c.184delT), and one rare deletion of two non-contiguous nucleotides (c.1287delT+c.1290delC). One patient had the most frequent GT homozygous deletion in exon2 of the NCF-1 gene encoding the p47(phox) subunit of NADPH oxidase. The carrier analysis was performed in 23 patients' mothers and 16 female relatives through molecular and FISH studies. No clear correlation between the severity of clinical symptoms and the type of mutation could be demonstrated. This study further supports the great heterogeneity of the disease and the notion that genetic analysis is a critical step in obtaining a definitive diagnosis for CGD. (C) 2009 Elsevier Ltd.

    A retrospective clinical and immunological survey was conducted in 60 patients with Chronic Granulomatous Disease. A prospective controlled non-randomized study of the efficacy of long-term IFNÎł treatment was carried out. The mean age at the time of diagnosis was 4.4 years; mean duration of follow-up was 10.4 years. Lung and skin infections were the most frequent manifestations both prior to diagnosis and during follow-up. Aspergillus species was the first cause of infection and of death in our cohort. The mortality rate was 13%. Long term prophylaxis with IFNÎł did not significantly change the rate of total infection per patient-year compared to controls (p=0.07). Our data provide clear evidence that protocols of continuing intensive surveillance and monitoring of compliance with anti-infective regimens may significantly improve the quality of life and long-term survival in patients with CGD. No evidence justifying long-term prophylaxis with IFNÎł was obtained
