risk of second primary cancer
Cancer survivors are at risk of developing a second primary cancer (SPC) later in life because of persisting effects of genetic and behavioural risk factors, the long-term sequelae of chemotherapy, radiotherapy and the passage of time. Standardized incidence ratios for developing a second primary cancer by type of NMSC, cancer site, and time (y) since diagnosis, females. Second cancers are not uncommon. The present study examines the incidence of second invasive primaries (other than NMSC) among patients with a history of BCC or SCC, as well as the risk of death in these patients. It is unlikely, however, that the use of toxic drugs or radiation has a significant contribution in the risk of second primary because NMSC are usually treated with local procedures with limited systemic effect (20, 21). If someone develops a second cancer, it could … However, comprehensive studies in second primary cancer (SPC) after the initial primary HPV-related cancer still remain warranted. We found also that women with clear cell and endometrioid histopathology of endometrial cancer had an elevated risk of second kidney cancer (4.9‐fold and 1.5‐fold, respectively). One exception is prostate cancer, for which the risk of death, in our study, was reduced in patients with a BCC history. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Chemotherapy benefits should be weighed against the risks of second primary malignancy. Exposure to UV light has been linked to non-Hodgkin's lymphoma through immune system suppression (23), although the relationship is weak. COVID-19 is an emerging, rapidly evolving situation. Confidence intervals were calculated assuming a Poisson distribution (13). Figure 2 It is acknowledged that radiation treatment is associated with a risk of developing second primary cancer (SPC) which can occur in the lifespan of patients following treatment (Xu et al 2008). The stage at diagnosis was similar in both groups (women with a NMSC: 149 cases: stage 0, 0.4%; stage I, 61%; stage II, 32%; stage III, 4%; stage IV, 4%; women without a NMSC: 3,325 cases: stage 0, 0; stage I, 63%; stage II, 31%; stage III, 2%; stage IV, 4%; P = 0.77). The purpose of this study was to assess the risk of developing a second primary cancer (SPC) after a first potentially-HPV-related cancer, and to analyze the sites where SPCs most frequently occurred in these patients. After bladder cancer, second primary malignan-cies were most commonly diagnosed among survivors of lung, prostate, colorectal, and kidney cancers. doi: 10.1016/j.vaccine.2012.07.055. Thank you for sharing this Cancer Epidemiology, Biomarkers & Prevention article. doi: 10.1001/jamanetworkopen.2018.1999. KatarzynaBialasiewicz / Getty Images Types . For every case, the Cancer Registry includes information on diagnosis according to the International Classification of Diseases, 9th edition (ICD-9) code (ICD-10 since 2002), date of diagnosis, tumor grade, tumor morphology, date of birth, sex, vital status, and since a few years stage. Br J Cancer. They unanimously found that accounting for other risk factors in the analyses had little effect on the risk of cancer in patients with and without a history of NMSC. Here, we attempt to quantify the risk, using data from the large population-based California Cancer Registry (CCR).
