Bisphosphonate therapy in multiple myeloma patients significantly reduces pathological fractures and skeletal events. While direct analysis showed no mortality benefit, network analysis suggested zoledronate may lower mortality risk.
Area of Science:
- Oncology
- Pharmacology
- Clinical Medicine
Background:
- Multiple myeloma is a cancer of plasma cells, often leading to skeletal complications.
- Bisphosphonates are commonly used to manage bone disease in multiple myeloma patients.
Purpose of the Study:
- To evaluate the association of bisphosphonate therapy with mortality, fractures, and skeletal-related events in multiple myeloma.
- To compare bisphosphonates against placebo or no treatment using direct and network meta-analysis.
Main Methods:
- Systematic review and meta-analysis of clinical trials involving bisphosphonates for multiple myeloma.
- Direct meta-analysis to assess overall bisphosphonate effects.
- Network meta-analysis to compare specific bisphosphonates and placebo/no treatment.
Main Results:
- Bisphosphonates were associated with reduced rates of pathological fractures and skeletal-related events.
- Direct meta-analysis found no significant association between bisphosphonates and mortality.
- Network meta-analysis indicated that zoledronate was associated with a lower risk of mortality compared to placebo or no treatment.
Conclusions:
- Bisphosphonates are effective in reducing skeletal morbidity in multiple myeloma.
- Zoledronate may offer a survival benefit in multiple myeloma patients, warranting further investigation.

Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...
01:25Multiple Voltage Sources
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.
Batteries are...
