Summary
Osteosarcoma, a rare bone cancer, has seen no survival improvement for decades. New therapies targeting metastatic cells and the tumor microenvironment are urgently needed to improve patient outcomes.
Area of Science:
- Oncology
- Cancer Biology
- Translational Medicine
Background:
- Osteosarcoma is the most common bone cancer in young people.
- Survival rates have not improved in 40 years, with lung metastasis being a major challenge.
- Current treatments (chemotherapy, surgery) are insufficient against metastatic osteosarcoma.
Purpose of the Study:
- To review recent preclinical and clinical studies on osteosarcoma.
- To highlight novel therapeutic strategies targeting metastatic potential and the tumor microenvironment.
- To inform potential changes in osteosarcoma treatment and improve patient survival.
Main Methods:
- Review of recent scientific literature and conference presentations.
- Analysis of data from preclinical studies and clinical trials.
- Synthesis of information on osteosarcoma cell biology and tumor microenvironment.
Main Results:
- Significant challenges exist due to tumor complexity, heterogeneity, and lack of adequate models.
- No drugs specifically targeting the tumor or microenvironment are standard in first-line treatment.
- Recent research shows promise for new therapeutic approaches.
Conclusions:
- New therapies are essential to combat osteosarcoma metastasis and improve survival.
- Addressing tumor cell and microenvironment heterogeneity is critical.
- Emerging research may offer future treatment advancements for osteosarcoma patients.

9.0K
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...

02:57Targeted Cancer Therapies
8.1K
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.

02:56Treatment Resistant Cancers
3.5K
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...

03:03mTOR Signaling and Cancer Progression
4.1K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
