Adjuvant hormone therapy for breast cancer BCTT

The committee also recalled that the models use different treatment durations for the 3CDK 4/6 inhibitors, which it does not consider plausible (see section 3.10). The committee noted that there is no evidence of a difference between the 3 treatments (see section 3.6) and that it is appropriate to consider a class effect for the CDK 4/6 inhibitors (see section 3.7). It concluded that, assuming the clinical effectiveness of abemaciclib, palbociclib and ribociclib is comparable, a cost-comparison approach is preferred. The company estimated progression-free survival on first-line treatment and pre-progression death using the MONARCH 3 data for abemaciclib (with an aromatase inhibitor) and an aromatase inhibitor alone. It used the hazard ratios for palbociclib and ribociclib from the network meta-analyses relative to the aromatase inhibitor data from MONARCH 3. The ERG noted inconsistency in the company’s approach and explained that hazard ratios from the network meta-analyses should be used for all 3 treatments (abemaciclib, palbociclib and ribociclib).

• ICERs were generated with different values, and parameters that exerted the greatest influences on the ICER at the WTP threshold of $37,738 were presented using a tornado diagram.
• Management of side effects requires providers’ thorough assessment, establishing trust, and follow-up so that patients will be invested in their medication management.
• Men with early-stage ER-positive breast cancer who receive adjuvant therapy are usually treated first with tamoxifen.
• Afterwards, there are 7 days off treatment during a 28-day treatment cycle period.
• According to the study of tevaarwerk et al.20, the survival probability of advanced breast cancer patients at the 15-year was approximately 5%.

In spite of our best efforts there are some data limitations our study. A limitation of our study is that the switch involving AI for two-to-three years followed by tamoxifen up to five years was not included in the analysis. However robust clinical data for this arm is not available and hence it could not be included in the analysis. When the local recurrences are compared between starting with AI vs tamoxifen, we see there is a significant decrease in recurrences (30%) during the first year of therapy when switch is started with AI and not subsequently.

50 All ICERs from the published analyses were less than $100 K (2010 USD) per life years and the majority less than $50 K (2010 USD) per life year. All ICURs with the exception of the analysis by Gil et al comparing anastrazole to tamoxifen were under the threshold of $100 K (2010 USD) per QALY and the majority under $50 K per QALY. Even though ICERs and ICURs varied somewhat amongst the analyses, the publications conveyed a consistent message. The 18 studies generally indicate that adopting aromatase inhibitors as first line therapy is good value for money when compared to tamoxifen since few of the studies exceeded commonly accepted thresholds.

Like aromatase inhibitors, these drugs work against estrogen, but in a different way. Aromatase inhibitors are a central part of treatment for post-menopausal women with ER-positive breast cancers. I’ve written about the use and value of tamoxifen, which is a similar drug used primarily for younger women. Aromatase inhibitors, commonly referred to as AIs, serve the same purpose in limiting or blocking estrogen and making it unavailable to cancer cells, which rely on estrogen to help them grow.

Hot flashes, night sweats, and vaginal dryness are common side effects of all hormone therapies. Hormone therapy also may disrupt the menstrual cycle in premenopausal women. Decisions about the type and duration of adjuvant hormone therapy are complicated and must be made on an individual basis in consultation with an oncologist. Aromatase inhibitors block the conversion of androgens to estrogens via the aromatase enzyme, resulting in up to a 95% decrease in endogenous estrogen levels. This mechanism of action differs from that of tamoxifen, which effectively blocks estrogen’s effect via competitive inhibition of estrogen binding to ERs and an antagonist (and agonist) for ER and down-regulates expression of genes controlled by ER expression.

Exemestane may be more expensive than similar breast cancer medications, such as letrozole. But exemestane costs significantly less than other breast cancer treatments, such as Kisqali or Ibrance. To find out which treatment options might cost less and still be effective for your condition, talk with your doctor. Women usually begin the drug after undergoing surgery to remove a breast tumor. They typically remain on the drugs for five to 10 years, depending on how likely the cancer is to return.
