Topic

Milestone improvements on prevention and treatment of cancers based on knowledge of patients' genetic changes

 

Abstract

Special emphasis will be devoted to:

1)Platins in the treatment of BRCA1-dependent breast cancers

2)SELINA - clinical trial on lowering the risk of malignancies by optimizing selenium levels in females from families with hereditary breast cancer

3)Arsenic as prognostic and risk factor of cancers.

     

     

    Ad 1)

    Aim. To evaluate in a contemporary cohort the impacts of chemotherapy and oophorectomy on survival for breast cancer patients with a BRCA1 mutation.

    Method. We reviewed the pathology reports and medical records of 372 women with breast cancer and a BRCA1 mutation, diagnosed from 2005 to 2017, between the ages of 25 and 65 and followed them for death from all causes and death from breast cancer. Death was ascertained through the Poland vital statistics registry. We performed survival analysis to evaluate the impacts of chemotherapy (including neoadjuvant cisplatinum) and of oophorectomy on survival.

    Results. After a mean follow-up of 5.6 years (median 5.2), 66 of the 372 women died; 56 of the deaths were from breast cancer and 6 were from ovarian cancer. 127 women received neoadjuvant cisplatinum and 245 women received other chemotherapies. Cisplatinum (versus all other therapies) was associated with a hazard ratio of 0.42 (95%CI 0.20-0.87) on breast cancer-specific survival. The 10-year actuarial all-cause survival for women who had both cisplatinum and an oophorectomy was 94.4%. The 10-year all-cause survival for women who had neither cisplatinum nor an oophorectomy was 65.4% (p < 0.01).

    Conslusions. Cisplatinum and oophorectomy are effective therapies for women with breast cancer and a BRCA1 mutation.

    Aim. Prospective observational studies showed that blood selenium (Se) levels associated with significantly lower risk of cancers can be identified in Polish females from families with hereditary breast cancers (HBC). For BRCA1 mutation carriers it is: 70-89 µg/l at age <50 yrs (OR~12) and 95-120 µg/l at age ≥50 yrs (OR~4). For females without detected BRCA1 mutation but from families with pedigree/clinical features of HBC it is 98-108 µg/l (OR~5).

    The main goal of SELINA is validation of hypothesis that optimization of Se level by supplementation or diet changes can decrease the risk of malignancies in groups described above.

    Method. 7000 females (including 1200 BRCA1 carriers) from families with HBC and deficiency or excess of Se will be recruited and randomly qualified to one of the following arms: “placebo”, prospective observational, supplement (Sodium Selenite) or diet modification. Blood Se level will be  systematically measured using ICP-MS and appropriately optimized. Follow-up will take 5 yrs.

    Results. At present we are performing recruitment. It is planned to close it at the end of 2019.

    Conclusion. SELINA is the first clinical trial aimed to decrease the risk of cancers by  active control of blood selenium levels . All interested scientists/institutions are welcome for collaboration.

    Background. Inherited mutations of high risk can explain only a few percent of cases of breast carcinoma. Environmental factors like exposure on metals may play role in such cases. Arsenic (As) is known as a potent carcinogen. Knowledge of chronic low level exposure is limited to a few studies.

    Aim. Authors aim was to determine if blood arsenic level may reflect cancer risk among women in Poland.

    Method. Cohort of 1702 healthy women, aged 40 and above was set. Only women without BRCA1 mutations were enrolled. Blood arsenic level was determined by inductively coupled plasma mass spectrometry. Statistical analysis was performed using Cox regression model for equal quartiles of arsenic levels.

    Results. Over an average of 4.5 years (range 0.7 to 7.3) of follow-up and 7,731 person-years, there were 110 incident cases of cancer diagnosed in the cohort. Annual breast cancer incidence rate is was 4.9 times greater than the expected risk based on Polish statistics. Women in the highest quartile of arsenic had a highly significant 12-fold increased risk of developing breast cancer compared to women in the lowest quartile (HR = 12.72; 95%CI 3.89-41.57). Cumulative incidence was 0.7% for quartile 1, 3.8% for quartile 2, 4.2% for quartile 3 and 9.5% for quartile 4.  Results were similar in the analysis including all incident cancers (HR quartile 4 vs. quartile 1 = 13.14; 95%CI 4.72-36.51). 

    Conclusions. Unexpectedly, the blood arsenic level may be particularly strong marker of low/high cancer risk in women.
