Background:
Immunocell therapy has been applied to patients with refractory cancer in clinical trials or as an unconventional cancer therapy, however the efficacy is still limited. To improve this efficacy, a combination therapy may be beneficial. Molecularly-targeted therapy acts directly on neoplasm cells to suppress their growth without causing myelosuppression.
Case Report:
Recently, we encountered three patients treated by immunocell therapy with imatinib mesylate (Glivec). One patient was diagnosed as having Philadelphia chromosome (Ph) (+) acute lymphoblastic leukemia (ALL) and had a relapse-free survival of more than 24 months. The other two were diagnosed as having GIST; a partial response was observed in one which lasted more than 21 months, while the other's disease has been stabilized for more than 25 months. No side-effects were observed, other than those mentioned in the directions for the use of imatinib.
Conclusion:
Immunocell therapy may have a potent therapeutic effect when used in combination with molecularly-targeted therapy, which has few side-effects.
Insights
Combining immunocell therapy with molecularly-targeted therapy, such as imatinib mesylate, shows promising results for refractory cancers. This combination approach demonstrated significant efficacy and minimal side-effects in three patient cases.
Area of Science:
- Oncology
- Immunotherapy
- Molecularly-Targeted Therapy
Background:
- Limited efficacy of current immunocell therapy for refractory cancers necessitates novel treatment strategies.
- Molecularly-targeted therapy offers a promising approach by directly inhibiting neoplasm cell growth with minimal myelosuppression.
Observation:
- Three patients with refractory cancers (Philadelphia chromosome-positive acute lymphoblastic leukemia and GIST) were treated with a combination of immunocell therapy and imatinib mesylate.
- One patient with acute lymphoblastic leukemia achieved over 24 months of relapse-free survival.
- One patient with GIST experienced a partial response lasting over 21 months, and another had stable disease for over 25 months.
Findings:
- The combination of immunocell therapy and imatinib mesylate demonstrated significant therapeutic effects in refractory cancer patients.
- Observed outcomes included prolonged relapse-free survival and sustained disease stabilization or partial response.
Implications:
- Immunocell therapy combined with molecularly-targeted therapy presents a potent and well-tolerated treatment option for refractory cancers.
- This combination strategy warrants further investigation in clinical trials to establish its broader applicability and optimize treatment protocols.
