New Research Finds That Routine Breast Cancer Tests Lead to Unnecessary Mastectomies and Chemotherapy – an article from Cancer News.

This article may temper the celebrity-endorsed enthusiasm for prophylactic mastectomies for those with BRCA mutations. In addition, another study out of Duke Cancer Institute followed women with a BRCA mutation who had been diagnosed with ovarian cancer, with one group having prophylactic mastectomies, and the other group receiving routine screening (mammograms/MRIs); you can read the article here.

Results: For women diagnosed at any age with BRCA 1 and 2 gene mutations and within the first four years after ovarian cancer diagnosis, prophylactic mastectomy was associated with a negligible gain in survival. For women diagnosed at age 60 or older, regardless of time since ovarian cancer diagnosis, the gain in survival months was also negligible. For women diagnosed at age 40 to 50 with BRCA 1 and 2 mutations and at least five years after an ovarian cancer diagnosis, the procedure was associated with a survival benefit of two to five months.

Bottom line: Although prophylactic mastectomy in BRCA gene mutation carriers has shown to decrease breast cancer incidence, the data does not confirm an increase in survival.

This is not the first article to document the potential efficacy of the antifungal agent, itraconazole. Multiple studies have shown that itraconazole inhibits cancer, not only through WNT inhibition, but also, through reversing MDR (multidrug resistance gene), inhibiting the Hedgehog pathway, and inhibiting angiogenesis. Human data have been published using itraconazole with prostate cancer, NSC lung cancer, triple neg breast cancer, ovarian cancer, as well as other cancers.
I refer physicians to the following article, “Repurposing Drugs in Oncology (ReDO)—itraconazole as an anti-cancer agent.” There are many drugs that have other FDA-approved indications that can and should be repurposed for use in cancer. I have personally used itraconazole in a patient with stage III NSC lung cancer who refused chemotherapy; he remained without progression of disease for 1.5 years, until he died of a drug overdose.

This is a groundbreaking article, as it safely increases the population who do not need to undergo chemotherapy, even by conventional guidelines. To reiterate what I have said in the past, conventional chemotherapy dosing probably adds the most benefit in the adjuvant setting, as opposed to metastatic disease, where it improves survival marginally.
Having said that, of course we do not want to use it in the adjuvant setting, if it does not improve progression-free or overall survival.
Bottom line: In the 50-75 year old age group, with ER+, Her-2 neg cancer and negative nodes, with an Oncotype Recurrence Score between 11 and 25, chemotherapy is NOT indicated. In women younger than 50, with Oncotype Recurrence Scores between 16 and 25, outcomes were only SLIGHTLY better in the chemotherapy group, so patients need to take that into consideration.

“Circulating Tumor Cells Predictive of Adjuvant Radiotherapy Benefit in Early Breast Cancer” – an article from Cancer Therapy Advisor can be accessed here.

This article validates what I have been proposing for quite some time; we should be checking for circulating tumor cells (CTCs) in early stage cancer.

In the US, we have a test called CellSearch, to search for CTCs in breast, prostate, and colorectal cancer. This test is FDA approved to help physicians make clinical decisions in patients with metastatic breast, prostate, and colorectal cancer.

We know the greater the number of CTCs, in a patient with metastatic cancer, the worse the prognosis. This study found that approximately 20% of patients with early stage breast cancer had CTCs. This study also showed that more aggressive treatment, adding radiation therapy, in those with CTCs, improved survival.

One of my mantras has always been, “the practice of medicine lags far behind the science of medicine.” This scientific data can and should be applied to the practice immediately. On early stage cancers, we should be checking for CTCs. If we are dealing with breast, colorectal, or prostate cancer, we can use the CellSearch test for those in the U.S. If it is a different type of cancer, we will need to send the patients’ blood outside of the country (such as a lab in Germany), where they test 6 other genetic markers for CTCs. If the patient has early stage cancer and CTCs, in my opinion, the adjuvant or neoadjuvant treatment should be continued until the CTCs are zero.
