Subscribers The overall 3-, 5-, and 10-year cumulative incidences for second primary BC were 0.9%, 1.6% and 4.4%, and for second primary non-BC were 2.3%, 3.9%, and 7.8%, respectively. This population-based cohort study includes 6,475 males with primary breast cancer and no subsequent breast cancer, and 85 males with a second primary breast cancer that developed after an initial breast cancer. Distinguishing second primary tumors from lung metastases in patients with head and neck squamous cell carcinoma. Among 18 230 people diagnosed with cancer during childhood, 388 (2%) were later diagnosed with second primary cancers; the estimated 30‐year cumulative incidence of second cancers was 4.4% (95% CI, 3.8–5.0%). Two of 59 (3.4%) cannabis users developed a second primary cancer, in comparison to 23 of 454 (5.1%) non-cannabis users. 39, no. Young and Suk [22] studied the incidence of endometrial, stomach, and thyroid cancer increased significantly after treatment with primary breast cancer was observed … There were no significant difference between patients in the cannabis and control group, “except that cannabis users were more likely to develop primary oropharyngeal cancer,” notes the abstract. Because it can take many years for cancers to develop, second cancers have been studied in types of cancers for which … Interestingly enough in men, there is a decreased risk of prostate cancer. The risk of a new primary cancer was five times as high as for the general population (SIR, 5.13; 95% CI, 4.65–5.67). DOI: 10.1200/JCO.2021.39.3_suppl.45 Journal of Clinical Oncology - Objective To assess differences in the risk of SPCs in patients with primary melanoma before (2005-2010) and after (2011-2016) the introduction and approval of ICIs. Background : An increased risk of second primary cancers has been reported in patients who survive small-cell carcinoma of the lung. Sporadic dMMR patients were older (mean 76.2 years vs 65.9 years, p = < 0.001), more likely to be female (65.2% vs 42%, p = < 0.001) and have a right sided primary (80.9% vs 32.8%, p = < 0.001), compared to patients with pMMR CRC. JCO Oncology Practice The cancer cells travel through the blood or lymphatic system and form a new cancer somewhere else in the body. Linda S. Sutton, MD, medical director at Duke Oncology Network, Duke University Health System in Durham, North Carolina, says that developing a secondary cancer from cancer treatment is a relatively rare occurrence. Background. Second primary cancers are a lifelong possibility for people who survive childhood cancer, and they are a leading cause of treatment‐related mortality among survivors. https://pubmed.ncbi.nlm.nih.gov/33329979/, Declaración presentada por la coalición europea por la justicia y políticas de drogas eficaces, una organización no gubernamental reconocida como entidad consultiva por el Consejo Social y Económico. Second primary cancers in cancer survivors now constitute 18% of all cancer diagnoses in the US Surveillance, Epidemiology and End Results (SEER) cancer registries [1, 2].In addition to this high morbidity, second cancers also lead to substantial mortality. Therefore, this study aims to estimate the contribution of gastric SPCs to the mortality of patients with a previous cancer. This study evaluated the incidence of secondary primary cancer among melanoma in situ (MIS) survivors. In the study, 46% of the patients were diagnosed with melanoma from 2005-2010 and 54% from 2011-2016. Although the risk of second primary cancer is recognised, quantification over time is lacking. Tuohimaa et al (2007) combined data from 13 cancer registries and found 23 and 39% increased risks of several second primary cancers after a melanoma or NMSC, respectively.
