[The pitfalls of lung cancer coding practices based on the evaluation of the National Cancer Registry]. / A tüdorákhoz kötodo kódolási gyakorlat buktatói a Nemzeti Rákregiszter felmérése alapján.

The quality of input data determines the reliability of epidemiological assessments. Thus, the verification of cases reported to the National Cancer Registry is required. The objective of our study was evaluating the reliability of cases diagnosed by lung cancer, exploring the patterns of erroneous reports. The validation of the 11,750 lung cancer cases reported to the Cancer Registry in 2018 was performed with the involvement of the recording hospitals, analyzing the characteristics of reports by gender, age and attributes of the reporting institutions. 81.3 percent of the reported cases was confirmed, in 40.4 percent of the false reports, malignancy was not present at all. Among the erroneous cases women and the elderly age group were overrepresented. The highest deleted rate occurred in Borsod- Abaúj-Zemplén county. As a conclusion, there is a strong need for the improvement of the efficiency in encoding lung cancer. The most common errors: confusion of malignant-benign, cancerous-non-cancerous and primary-metastatic lesions. The reliability is not affected by the role of individual institutions in the hierarchy of health care. The availability of reliable epidemiological data is crucial in the fight against cancer, which requires broad professional cooperation.

[Hungarian situation of melanoma incidence and mortality in the first two decades of 21st century]. / A melanóma hazai morbiditási és mortalitási helyzete a XXI. század elso két évtizedében.

Skin melanoma is not among malignancies with the highest incidences and mortalities worldwide; however, the observed constant increase in newly diagnosed cases is troublesome. According to the database of the Hungarian Cancer Registry, the number of newly reported cases doubled between 2001 and 2019, which is consistent with international data. Notwithstanding, within the same interval, Hungarian mortality did not change significantly according to the database of the Hungarian Statistical Office, which is in contrast to international trends. The increasing incidence together with unchanging mortality resulted in better survival rates and hence more favorable follow-up data in our country. Advancements in secondary prevention programs and better efficacy of modern therapeutic interventions in the last decade may have contributed to the observed improvement in the survival rates of Hungarian melanoma patients.
