Sleep Patterns and Cancer: New Evidence

Sleep disorders are common in both men and women. The body needs adequate sleep. Recent evidence shows the value of sleep to the body is to clean out waste molecules in the brain, allowing us to function better. This observation was even listed in Science as one of the most important scientific observations of 2013.


I found recent basic science and referenced clinical studies very important. Hakim and coworkers (Cancer Research 2014, volume 74, page 1329) studied mice which had experimental tumors TC-1 or 3LLC. If the mice were subjected to sleep disruption (using a mechanical sweeper during daylight hours to fragment the sleep patterns of the mice), the cancers grew faster and became larger. Also, these tumors in sleep deprived mice were ...

Screening Mammography Controversies in Oncology Practices

Recently there has been much ado about mammography. A Canadian study in 89,835 women, by A Miler and colleagues, Brit Med Journal 2014; 348, g366, showed no increased survival rate by screening mammography between ages 40 and 59. This has led to editorials and articles urging women at low risk not to have screening mammograms, especially between the ages of 40 and 49, which is...

Social medial in oncology practices have you been affected yet?

Social media is an opportunity for people to interact more broadly through the internet.  Until recently, this has not impacted oncology in any meaningful way. 


However, a recent article by H. West in The Oncologist 2013; 18:780 reviewed the current status of social media.

Oral Contraceptives May Reduce the Risk of Colorectal and Endometrial Cancers

We often see patients who are at high risk of cancer, either because they are relatives of our patients who have had cancer, or because they have had one cancer and are at risk of having other cancers.  An interesting paper has recently been published which relates to our attempts to initiate primary prevention in patients, and to d...

Do your breast cancer patients actually complete their treatment?

A recent study in Breast Cancer Research and Treatment 2013; 138:931 by C. Friese and co-authors has identified problems in compliance with prescribed endocrine therapy in breast cancer patients after primary surgery.  They found that in 743 women eligible for endocrine therapy in whom it was recommended, 11% of the studied patients...

Breast Cancer: To Neoadjuvant or Adjuvant, that is the Question

Neoadjuvant chemotherapy has never shown a significant impact on ovverall survival in breast cancer, so we have always wondered whether to give neoadjuvant therapy just to allow breast conservation, or to do adjuvant therapy postoperatively.

Now a new study, by von Minckwitz et al J Clin Oncol 2013; 31: 3623 has given hope that survival can be improved, and has shown statistically signi...

At last, evidence-based adjuvant chemotherapy for patients with resected pancreatic cancer.

Chemotherapy in the past had not been recommended as evidence-based therapy for patients who had resected pancreatic cancer.  The recently published CONKO-001 study has given us evidence we have been seeking to justify use of gemcitabine in such patients.  This study (H. Oettle and co-aut...

Proper Frequency of Screening Colonoscopy in Our Patients: American or British?

How often do we recommend repeat colonoscopy in our patients at risk of colon polyps or cancer? Do we just leave this to gastroenterologists and primary physicians, or do we make stronger recommendations to pour patents and our medical colleagues (e.g. at tumor boards)?
