More research needed into side-effects of chemo and hormone therapy

In our BCNA network, many members report unexpected, painful and ongoing side-effects during and after chemotherapy and hormone therapy; for example in a recent discussion on ‘hormone therapy and tendon issues’. Sometimes treating medical staff  seem to be unsure about causes and best treatment for side-effects. 

I read a study 'Incidence and severity of self-reported chemotherapy side-effects in routine care' (https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0184360#sec013 ) This study reports that knowledge about side-effects comes largely from clinical trials. There is little evidence coming from normal clinical care.

In this study 449 people with breast, lung or bowel cancer were interviewed and asked questions about their side-effects.  The study found that “3/4 of individuals undergoing chemotherapy in NSW will experience multiple side-effects during their treatment, and for over 60% this will include a serious side-effect.” The study found that side-effects were similar across the three cancer types.

The authors suggest that “this information is useful for both clinicians and policy makers, who typically make treatment and funding decisions for standard practice, but often on the basis of potentially unrealistic clinical trials. This work also confirms the need for side effects to be collected using patient-reported methods, to be monitored throughout chemotherapy treatment, and highlights the importance of observational data in providing information for decision-makers that is relevant to the clinical practice setting.” 

Have a look at this study; it is very interesting and readable, and brings up lots of questions and ideas. Although this study is about chemo side-effects, and does not include hormone therapy side-effects; I am thinking that a similar study is needed to measure hormone therapy side-effects in the real world.
