Insights

Systemic immunotherapy, like Interleukin-2, can reduce cancer metastases, making surgery a viable option for remaining lesions. This approach offers durable, disease-free survival for many patients with renal cancer or melanoma.

Area of Science:

  • Oncology
  • Immunotherapy
  • Surgical Oncology

Background:

  • Disseminated cancer with numerous metastases is challenging to treat with local destruction alone.
  • Systemic therapies that reduce metastatic burden are needed to improve the efficacy of local treatments like surgery.

Purpose of the Study:

  • To review the effectiveness of surgery for limited metastases after systemic immunotherapy.
  • To assess the potential for durable disease-free survival in patients treated with this combined approach.

Main Methods:

  • Review of patient data from studies involving systemic immunotherapy followed by surgical metastasectomy.
  • Analysis of outcomes, including disease-free survival and potential for cure.

Main Results:

  • Interleukin-2-based immunotherapy effectively reduces metastases in some renal cancer and melanoma patients.
  • Surgical removal of remaining oligometastases after immunotherapy leads to durable disease-free survival in a significant percentage of patients.

Conclusions:

  • Combining systemic immunotherapy with surgical metastasectomy is a promising strategy for managing disseminated cancer.
  • This multimodal approach can achieve durable remissions and potentially cure a subset of patients with renal cancer and melanoma.

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Targeted Cancer Therapies02:57

Targeted 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.
There are several types of targeted therapies against specific...
Cancer Therapies02:49

Cancer 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...
Cancer Vaccines01:30

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
