Research of Cancer Cases Among Long-Lived Women in Lviv Region (Ukraine) During 1991–2019 Years

Abstract

Cancer is the second leading cause of death worldwide. Aim of our study was to describe the spectrum of cancer among longlivers women in Lviv region (Ukraine) from database during 1991-2019. Material and methods. We studied 444 longlivers women aged 90+ who were diagnosed of cancer, treated and followed-up. Results. 104 women (23%) were diagnosed cancer to stage I, II -142 (32%), III -71 (10%), IV -57 (13%):other malignant neoplasms of skin (38.29%), breast (9.46%), colon (6.98%) and pancreas (4.95%) cancer. Diagnosis was confirmed cytology -169 (38.1%), histology-139 (31.3%). CT and MRI were used in rare cases in older women – 11(2.5%). Half of the women (227 or 51.13%) lived beyond 1 year after diagnosis. The rest is from 1 to 13 years. The relationship between life expectancy after diagnosis of cancer and type of treatment is weak (Сramer ratio ; Pearson's criterion ). Detected that the relationship between life expectancy after diagnosis and the age of patients at the time of oncologic diagnosis is weak too (Сramer ratio ; Pearson's criterion ). The relationship between life expectancy after diagnosis and stage of cancer is strong (Сramer ratio ; Pearson's criterion ). Conclusion. Aggressive anticancer treatments are less commonly used in cancer patients aged 90+, which may be one of the reasons for poorer survival due to comorbidities and natural causes. Life expectancy has relationship on the stage of the cancer, but does not have relationship on the age of the long-lived women and the type of treatment.
