Young immigrant women and cervical cancer screening: participation and lesions detected at the first screening round.

OBJECTIVES: to evaluate if the country of origin affects participation and outcomes of cervical cancer screening. DESIGN: retrospective cohort study. SETTING AND PARTICIPANTS: all Italian and foreign women resident in the Veneto region (North-Eastern Italy) who were born between 1986 and 1992 and who had been invited for the first time through the screening programme between 2011 and 2017 were identified and included in the survey. MAIN OUTCOME MEASURES: participation to screening was calculated along with the detection of Cervical Intraepithelial Neoplasia (CIN) grade 2 or 3 and of carcinoma, by citizenship. RESULTS: 96,105 (77.5%) Italians and 27,958 (22.5%) foreign women were included. Overall, the adjusted participation was 53.3%, with large differences among the geographical study areas. The value was highest for Italian women (56.4%), while women with other citizenships showed lower attendance: 45.5% for Eastern Europe, 44.8% for Sub Saharan Africa, 40.0% for Northern Africa, 38.5% for Central and Southern America, and 36.5% for Asia. The detection of CIN2+ was higher for women from Central and Southern America (23.0‰) or from Eastern Europe (17.9‰), while it was lower for those from Italy (11.9‰), Northern Africa (7.5‰), Sub-Saharan Africa (6.6‰), and from Asia (2.5‰) (p<0.001). CONCLUSIONS: cervical screening programmes should identify and face the barriers to participation of foreign women. This is particularly important for women from geographic areas with a high prevalence of disease, such as Central and Southern America and Eastern Europe.

Comparison of peripheral cannula outcomes, ultrasound-guided placement of deep veins versus blind insertion of superficial veins in children aged 0-18 years: A retrospective study.

BACKGROUND: The clinical use of ultrasound has increased the chances of successful insertion of all venous access devices, including short peripheral cannulas (SPC) and long peripheral catheters (LPC). The aim of the study was to compare the clinical performance of peripheral cannulas inserted using the traditional "blind" technique versus those inserted with ultrasound guidance (US). METHODS: In this retrospective study we compared 135 peripheral intravenous cannulations (PIVCs) with ultrasound guidance and 135 PIVCs with blind technique, inserted in children (0-18 years) in the emergency department. All devices were inserted using the catheter-over-needle technique. With the blind technique, superficial arm veins were cannulated using SPCs (1.9 cm, 24G; 2.5 cm, 22G; 3.2 cm, 20G), while with US, deeper non-palpable veins were accessed using SPCs of 3.2 cm, 24G; and LPCs of 6.4 cm, 22G; 6.4 cm, 20G. RESULTS: The accesses were removed electively in 66% of US-PIVCs, with an average duration of the device of 5.3 ± 4.0 days, but only in 30% of Blind-PIVCs, which presented an average duration of 2.5 ± 1.8 days. The longest dwelling time (8.7 ± 5.1 days) was observed in 20G LPCs inserted with US into the basilic vein of the arm; among Blind-PIVCs, the longest duration (3.0 ± 2.1 days) was observed in 22G SPCs inserted into the cephalic vein at the forearm. The most commonly encountered complication in both groups was accidental dislodgment. CONCLUSIONS: PIVCs with ultrasound guidance were apparently more effective than the blind ones, reducing the number of successive cannulations. Additionally, LPCs, with their greater length compared to SPCs, have proven to be more durable and may be recommended as emergency venous access in children requiring peripheral access for 4-15 days. Dislodgement should be reduced by improving the securement of the device.

Cancer incidence in immigrants by geographical area of origin: data from the Veneto Tumour Registry, Northeastern Italy.

Objective: We investigated whether there are differences in cancer incidence by geographical area of origin in North-eastern Italy. Methods: We selected all incident cases recorded in the Veneto Tumour Registry in the period 2015-2019. Subjects were classified, based on the country of birth, in six geographical areas of origin (Italy, Highly Developed Countries-HDC, Eastern Europe, Asia, Africa, South-central America). Age-standardized incidence rates and incidence rate ratio (IRR) were calculated, for all cancer sites and for colorectal, liver, breast and cervical cancer separately. Results: We recorded 159,486 all-site cancer cases; 5.2% cases occurred in subjects born outside Italy, the majority from High Migratory Pressure Countries (HMPC) (74.3%). Incidence rates were significantly lower in subjects born in HMPC in both sexes. Immigrants, in particular born in Asia and Africa, showed lower rates of all site cancer incidence. The lowest IRR for colorectal cancer was observed in males from South-Central America (IRR 0.19, 95%CI 0.09-0.44) and in females from Asia (IRR 0.32, 95%CI 0.18-0.70). The IRR of breast cancer appeared significantly lower than Italian natives in all female populations, except for those coming from HDC. Females from Eastern Europe showed a higher IRR for cervical cancer (IRR 2.02, 95%CI 1.57-2.61). Conclusion: Cancer incidence was found lower in subjects born outside Italy, with differences in incidence patterns depending on geographical area of origin and the cancer type in question. Further studies, focused on the country of birth of the immigrant population, would help to identify specific risk factors influencing cancer incidence.

Quality control on digital cancer registration.

Population-based cancer registration methods are subject to internationally-established rules. To ensure efficient and effective case recording, population-based cancer registries widely adopt digital processing (DP) methods. At the Veneto Tumor Registry (RTV), about 50% of all digitally-identified (putative) cases of cancer are further profiled by means of registrars' assessments (RAs). Taking these RAs for reference, the present study examines how well the registry's DP performs. A series of 1,801 (putative) incident and prevalent cancers identified using DP methods were randomly assigned to two experienced registrars (blinded to the DP output), who independently re-assessed every case. This study focuses on the concordance between the DP output and the RAs as concerns cancer status (incident versus prevalent), topography, and morphology. The RAs confirmed the cancer status emerging from DP for 1,266/1,317 incident cancers (positive predictive value [PPV] = 96.1%) and 460/472 prevalent cancers (PPV = 97.5%). This level of concordance ranks as "optimal", with a Cohen's K value of 0.91. The overall prevalence of false-positive cancer cases identified by DP was 2.9%, and was affected by the number of digital variables available. DP and the RAs were consistent in identifying cancer topography in 88.7% of cases; differences concerned different sites within the same anatomo-functional district (according to the International Agency for Research on Cancer [IARC]) in 9.6% of cases. In short, using DP for cancer case registration suffers from only trivial inconsistencies. The efficiency and reliability of digital cancer registration is influenced by the availability of good-quality clinical information, and the regular interdisciplinary monitoring of a registry's DP performance.

Interval colorectal cancers after negative faecal immunochemical test in a 13-year screening programme.

OBJECTIVE: To assess faecal immunochemical test sensitivity for cancer in a very large population-based cohort followed up for six rounds with biennial faecal immunochemical test repetition. METHODS: This study is based on interval colorectal cancers diagnosed in a cohort of subjects aged 50-69 undergoing repeated faecal immunochemical test screening (six rounds) from 2002 to 2015. Test sensitivity was calculated using both the Proportional Interval Cancer Rate and the Interval Cancer Proportion method. RESULTS: Among 441,647 faecal immunochemical tests (123,347 individuals), 150 interval colorectal cancers were detected after a negative faecal immunochemical test. Interval colorectal cancer incidence rate was 1.87 per 10,000 person-years (95%CI: 1.60-2.20), and it was higher during the second interval year (rate ratio: 1.78; 95%CI: 1.28-2.47), for proximal locations (rate ratio: 3.00; 95%CI: 1.92-4.68), and among 60-71 year old subjects (rate ratio: 2.37; 95%CI: 1.61-3.50). The Proportional Interval Cancer Rate was 13.1%, with an overall faecal immunochemical test sensitivity of 86.9% (95%CI: 84.7-89.0). Sensitivity was lowest at the first round (81.5%; 95%CI: 75.6-86.2), and increased to 91.9% (95%CI: 83.9-96.5) for subsequent rounds. Applying the Interval Cancer Proportion method, sensitivity was 83.9% (95%CI: 81.3-86.2), and it was highest at the first round (89.0%; 95%CI: 85.7-91.6), ranging between 73% and 83.1% at subsequent rounds. CONCLUSIONS: A faecal immunochemical test sensitivity for cancer higher than 80% resulted in a low incidence of interval colorectal cancers, representing an accurate estimate of one of the major limits of screening programmes. Due to intrinsic biases, the Proportional Interval Cancer Rate and the Interval Cancer Proportion methods generated different trends in faecal immunochemical test sensitivity by screening round.
