Summary
A small percentage of multiple myeloma patients may achieve a cure. Further research into sensitive detection methods for residual disease is crucial for identifying patients with potential cure.
Area of Science:
- Hematology
- Oncology
- Clinical Research
Background:
- Multiple myeloma is a hematologic malignancy.
- Complete remission (CR) is a key treatment goal.
- Long-term outcomes and cure potential require further investigation.
Purpose of the Study:
- To evaluate the long-term outcomes of patients with multiple myeloma achieving complete remission.
- To assess the potential for sustained cure in a subset of these patients.
- To identify factors associated with long-term remission and cure.
Main Methods:
- Retrospective analysis of 792 multiple myeloma patients treated between 1987-2010.
- Assessment of complete remission rates after 18 months.
- Long-term follow-up for a subset of 60 patients treated between 1987-1998.
Main Results:
- 167 out of 792 patients achieved complete remission.
- In a cohort of 60 patients with long follow-up, the latest relapse occurred after 11.8 years.
- 13 patients maintained complete remission for over 12 years (range 12-22 years), suggesting a potential cure rate of approximately 3% for the overall treated cohort.
- Sensitive techniques for residual disease detection are recommended for patients in apparent CR.
Conclusions:
- A subset of multiple myeloma patients may achieve a durable, long-term cure.
- Sustained complete remission for over 12 years indicates a potential cure.
- More sensitive methods beyond immunofixation are needed to accurately identify patients with minimal residual disease and potential for cure.

02:57Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

02:50Combination Therapies and Personalized Medicine
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

02:56Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
02:49Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
