Mapping cancer's drug resistance could improve treatment [not bc-specific]

The [laboratory and computational] techniques – developed [by Weill Cornell Medicine] with researchers from the New York Genome Center (NYGC) and the Broad Institute of the Massachusetts Institute of Technology and Harvard University – will allow researchers in principle to anticipate resistance mechanisms and suggest optimal drug doses and combinations across cancer types....

Combining two or more treatments that work in different ways is one promising approach, but for most cancers it is impractical to test in clinical trials the many combinations that are now possible.

Landau and his colleagues developed their new technique to reveal likely resistance pathways and optimal drug regimens in advance, with relatively inexpensive and comprehensive laboratory testing. That could allow subsequent tests, including clinical tests, to focus on more promising treatment combinations.

The scientists demonstrated their approach using lung cancer cells whose malignant growth is driven by the overactivity of a growth-factor receptor called EGFR... The results indicated that resistance can arise to these drugs and combinations from dozens of different genes involving multiple pathways... One of the most striking and important findings was that resistance to a combination of two drugs can arise more or less out of the blue – from genes that confer no resistance to either drug alone. The results suggest that the effects of two drugs in combination may be impossible to predict completely from their effects when used singly...

The researchers did, however, develop a framework for using genotype fitness mapping to identify promising drug doses and combinations. They concluded that for many EGFR-driven lung cancers, combining an EGFR inhibitor and an MEK inhibitor is seemingly optimal, though single-drug therapy with an MEK inhibitor might be better if certain other mutations are also present – and for many patients alternating combination therapy with MEK-inhibitor monotherapy might work best.

FDA Calls for Boxed Warning on All Breast Implants

Agency seeks to boost genuinely informed patient consent

The FDA issued a draft guidance recommending that manufacturers of breast implants include a boxed warning that clearly spells out the risks of their products. The agency also called on implant-makers to include a patient decision checklist and list the devices' ingredients, and updated its own recommendations for implant rupture screening.

Special garments ease an agonizing ailment for women. But insurance may not pay.

Many lymphedema patients struggle to get health insurers to pay for compression garments. Coverage varies among private insurance plans, and for many patients it is limited. Although Medicaid programs cover some of these expenses, Medicare does not.

Women with interval breast cancer -- detected between two routine screening mammograms -- have an increased risk of developing other types of cancer.

Breast cancer detected between two routine screenings is called interval cancer, and it tends to be more advanced, more aggressive and to have a worse prognosis than cancers found during screenings.

Health-care system causing rampant burnout among doctors, nurses

As many as half of all clinicians suffer from the problem, creating risks to patients, malpractice claims and absenteeism, study finds.

Imagine a health-care system in which doctors and nurses are so exhausted and beaten down that many of them work like zombies — error-prone, apathetic toward patients and at times trying to blunt their own pain with alcohol or even suicide attempts.

That is what America's broken health care system is doing to its health workers, according to a 312-page report released Wednesday by the National Academy of Medicine, one of the country's most prestigious medical institutions.

"It's incredibly inefficient, and the workload is unsustainable," said Liselotte Dyrbye, a doctor and researcher at the Mayo Clinic. "The system is built for billing and not taking care of patients."

Wednesday's report outlined a hefty list of needed changes...

Blame rising cancer overdiagnosis on 'irrational exuberance' for early detection

Here's some good news for a change about cancer: Cancer mortality — the rate of death from cancer — has fallen substantially over the last four decades. There is also, however, some not-so-good news: Cancer incidence — the rate of cancer diagnoses — has been rising. This doesn't reflect increasing dangers in our environment, but a danger in our medical system. Even though overall mortality from cancer is falling, the overall incidence is rising.... overdiagnosis — the diagnosis of cancers not destined to cause symptoms or death. This exuberance began with the observation that patients in whom cancer was detected early lived years longer than those in whom cancer was detected later. The simple inference was that they had benefited from early detection. Many doctors recognized the logical fallacy here, one that has nothing to do with overdiagnosis: If we start the clock earlier in the course of disease, patients will always appear to live longer — even if their time of death is unchanged. These are not epidemics of disease. They are epidemics of diagnosis. Paradoxically, overdiagnosis helps fuel the exuberance for early detection. Survival rates skyrocket either because the clock started ticking earlier or the disease was not destined to cause death. More people appear to be cured. And more survivors — as well as more politicians — advocate for more early detection. Overdiagnosis isn't the only danger caused by early detection. False alarms are another... Early detection is great for the business of medicine.

Researchers uncover dangers of ringing a bell to celebrate 'victory' over cancer

Williams, who led the study while completing his residency in radiation oncology at the Keck School of Medicine of USC, expected the bell to have a positive impact on patients. After all, they rang it in celebration. Instead, people who rang the bell viewed their overall treatment as more distressing than those who didn't...

When he surveyed the patients again after three months, the effect had worsened. Williams speculates that ringing the bell locks in painful memories of treatment through a phenomenon called emotional arousal...

Now Williams, who works in a cancer treatment center in Santa Maria, Calif., encourages his patients — especially those who went through a prolonged and painful treatment regimen — to consider subtle and calm ways to celebrate.

Lymphedema Bill of Rights - there is legislation to add lymphedema treatment to Medicare. It has not gotten out of committee. This site describes lymhedema, who in congress is on board/who is not, and has links to your representatives, as well as boiler plate statements to include in letters. If Congress keeps getting these, maybe they will start listening. Maybe tie it to voting for a candidate. I wrote a letter, response from my representatives was rather pathetic. https://www.stepup-speakout.org/

Exercise very regularly, if not at the gym, then walk/hike, weights, stretch, swim, x-country ski etc.

Supplements: GAIA turmeric-joint; glucosamine-chondroitin; magnesium glycinate; biotin; potassium-iodine; C; B-complex ; D; Fish oil (but not now). For a year or so after bi-lateral used Juven Nutritional therapy for wound healing with 7g arginine, 7g glutamine for about a year. Often add turmeric to meals. Ran out of fish oil supplement that I liked, other brand caused fish burps, so have not taken for a while

2009 ER+ left breast. 52 yrs. Lumpectomy, Sentinel node removal, negative. Radiation 6 weeks, tamoxifen 5 years. Dense lumpy left breast, normal right. Acupuncture offered at facility as part of integrative medicine. It really helped with anxiety/stress during radiation treatment.

2016 ER+ left breast. Probably a new cancer, but unknown. 4 rounds TC Aug-Oct 2016, Bi-lateral (my choice) Nov 2016, no reconstruction. 2 sentinel nodes remove, negative. Cold Capping using Chemo Cold Caps (DIGNICAP not available). Anastrozole 1 mg starting May 2017. Joint issues noticed immediately. Stopped Anastrozole after 3-4 months due to joint stiffness in. After several months of no AIs, fingers were feeling better. Started tamoxifen March 2018

10/2018 noticed stiffness and some trigger finger again. Was eating meat a lot more (daily) than normal. Usually 1-2 /wk. Have cut way back on the meat, seems to help, but one finger still very prone to trigger finger. Trigger finger seemed to be getting better, but now 4/2019 seems worse, is it the break from added turmeric to meals?

7/19/2019 - swelling in R-arm, opposite side from where lymph nodes removed. Noticed 6/18/2019. Could have been swelling earlier but wearing long sleeves. Trip to urgent care. They did ultrasound, concerned that there might be a clot, there was not. Started seeing lymphatic therapist 7/2/2019.

8/2019 CT, Breast/chest , neck/thyroid ultra sound

9/2019 DR ordered biopsy, said it could be lymphoma, cancer, benign lymphatic. Biopsy R-axilla. Cancer. Genetic test showed no known markers (20+ looked for)

9/29/2019 PET scan, no indication of spread. Arimadex and Ibrance prescribed to shrink tumor prior to surgery

They turn to Facebook and YouTube to find a cure for cancer — and get sucked into a world of bogus medicine

Mari pressed kale leaves through the juicer, preparing the smoothie that she believed had saved her life. The video, first uploaded in 2016, remains on YouTube, but there's an "important update" attached to the video's description. It was written by Liz, her niece, a year later. Mari's cancer had returned, the note said, and she had died.

...the web of false, misleading and potentially dangerous cancer "cures" and conspiracy theories isn't just there for those who stumble into it accidentally. More often it ensnares people who are reeling from bad news and groping for answers.

PFAS: Controlling, Preventing, and Understanding Exposure

PFAS, or perfluoroalkyl and polyfluoroalkyl substances, are ubiquitous fluorinated organic compounds found widely in manufactured products, from firefighting foam to stain-resistant carpets. These water- and oil-repellent compounds are known to degrade slowly over time, and have been found in humans, drinking water, and even in Arctic ecosystems.

What do we know about human exposure to PFAS? How can contaminated media be treated? How can these compounds be controlled, and how can exposure be prevented? Last month, the Environmental Health Matters Initiative of the National Academies of Sciences, Engineering, and Medicine hosted a two-day workshop that brought together experts and stakeholders from academia, research, government, and industry to address these and other important questions about PFAS.

I'd be curious to find out how many patients actually see the box that their implants come in. Is it like when you wear shoes out of the shoestore and they send you home with an empty shoebox? Somehow I just don't think we'd see the box anyway.

They also talk about brochures from the makers that help patients decide about reconstruction options. I sure didn't get any of those from my PS!

Re the implants, I am required to sign a page-long warning every time I get a scan. Given the issues raised, I don't think the box that the implants come in will be relevant. I feel certain that anyone getting them will be required to sign an extensive disclosure before surgery. As a practical matter, the record of disclosure must be acknowledged and scanned into the electronic medical record. So we can expect it to be on 8.5x11 paper (in the US) or other standard size paper. I just hope that there is meaningful "education" before the day of surgery! As serious as some of the problems have been, I think that if they do not make meaningful disclosures *before* the date of surgery, purveyers and surgeons are going to be inviting liability. These guys aren't stupid.

Anticoagulants and breast cancer survival, a nationwide cohort study

Abstract

Background: Various components of the coagulation cascade have been linked to breast cancer (BrCa) progression. In vivo results suggest that anticoagulants possess anticancer properties, but there are virtually no studies in human populations. Our nationwide study explored the association between anticoagulant use and BrCa survival. Methods: All anticoagulants used from 1995-2015 in women (n=73,170) diagnosed with invasive BrCa in Finland between 1995-2013 were identified from the national prescription database; women were identified from the Finnish Cancer Registry. Cox regressions were performed to analyze BrCa survival as a function of pre- and post-diagnostic anticoagulant use; analyses were conducted for different anticoagulant subtypes and overall. Models were adjusted for age, mammography screening, tumor clinical characteristics, comorbidities, statin use, antidiabetic use, and antihypertensive use. To control for immortal time bias, post-diagnostic anticoagulant use was analyzed as a time-dependent variable. Results: At a median of 5.8 years after BrCa diagnosis, 10,900 (15%) women had died from BrCa. In total, 25,622 (35%) women had used anticoagulants during the study period. Post-diagnostic anticoagulant use increased the risk of BrCa death (HR=1.41, 95% CI 1.33-1.49). The risk was especially high for low-molecular weight heparin, although the effect disappeared in long-term users. Conclusion: Anticoagulant use provides no clinical benefit for BrCa survival; however, the association between thrombosis and cancer might mask potential survival benefits. Impact: Future pharmacoepidemiological studies should adjust for anticoagulant use. Research should focus on the use of new oral anticoagulants because these are rarely studied and might be associated with improved BrCa survival.

3D-Printed Device Finds 'Needle in a Haystack' Cancer Cells by Removing the Hay

Finding a handful of cancer cells hiding among billions of blood cells in a patient sample can be like finding a needle in a haystack. In a new approach enabled by 3D-printed cell traps, researchers are removing the hay to expose the cancer cells.

Next steps will be to narrow the channels in the device, test white blood cell removal without the use of biotin, boost the percentage of white cell extraction and connect cell traps to increase trapping capacity.

Chemotherapy may spread cancer and trigger more aggressive tumours, warn scientists

Many are given chemotherapy before surgery, but the new research suggests that, although it shrinks tumours in the short term, it could trigger the spread of cancer cells around the body.

It is thought the toxic medication switches on a repair mechanism in the body which ultimately allows tumours to grow back stronger. It also increases the number of 'doorways' on blood vessels which allow cancer to spread throughout the body.
