Breakthrough Clinical Results
Caris Life Sciences announced a study published in Scientific Reports demonstrating the accuracy and clinical utility of its Caris Assure® blood-based biopsy assay. This single assay combines comprehensive molecular profiling of over 23,000 genes across DNA and RNA in plasma and the buffy coat. The study validates Caris Assure®'s use in multi-cancer early detection (MCED), achieving high sensitivities and specificity. It also shows significant predictive power for minimal residual disease (MRD) and recurrence monitoring. Currently used for therapy selection, Caris is pursuing regulatory pathways to expand its use to early detection and monitoring.

Incidence and Prevalence
Global Cancer Epidemiology: Recent Estimates and Burden
Global Incidence and Prevalence of Rare Cancers
According to 2022 GLOBOCAN estimates, rare cancers (defined as those with an incidence rate of fewer than 6 cases per 100,000 individuals) accounted for 26.7% of all new cancer cases (5,347,784 cases) and 30% of all cancer-related deaths (2,959,369 deaths) worldwide.
Bladder cancer was the most common rare cancer, with an incidence rate of 5.58 per 100,000, followed by non-Hodgkin lymphoma (5.57) and leukemia (5.26).
Mortality rates were highest for pancreatic, esophageal, and brain cancers, reflecting their aggressive nature and limited treatment options.
Significant regional disparities were observed, with Europe and North America reporting the highest incidence rates for bladder cancer and leukemia, while Asia bore the largest absolute burden of rare cancers.
Cancer Burden Metrics and DALYs
A study on melanoma burden found 3.67 DALYs per melanoma case, 90.81 per 100,000 inhabitants, or 32.67 per death due to melanoma. Years of life lost (YLL) accounted for 80.4% of the total DALY for melanoma.
Stages I, II, III and IV patients at diagnosis generated 27.8%, 32.7%, 26.2% and 13.3% of the total YLL, respectively.
For time spent in each stage, localised melanomas, node metastatic melanomas, and distant metastatic accounted for 34.8%, 52.6% and 12.6% of the total YLD (years of life with disability), respectively.
Special Populations and Cancer Risk
In a study from Mexico, the standardized incidence ratio (SIR) of cancer in renal transplant recipients was 4.1 (95% CI 3.2-5.1) compared to the general population, based on GLOBOCAN 2012 data.
The relative risks of male and female transplant recipients were 4.6 and 3.5 times greater than the risk of cancer in the general population, respectively.
Regional Data: Canada
In Canada, using the 6/100,000/year threshold, the incidence proportion (IP) of rare cancers ranged from 9.7% (95% CI: 9.6, 9.7%) to 17.0% (95% CI: 16.9, 17.0%).
Using the <15/100,000/year threshold in Canada, rare cancers ranged from 19.2% (95% CI: 19.1, 19.3%) to 52.5% (95% CI: 52.0, 53.0%).
The adjusted probability of being diagnosed with a rare cancer was highest among those aged ≤19 years in Canada.
Methodological Considerations
The melanoma study used a melanoma disease model to predict patient evolution from diagnosis until death. The model was applied to 8016 melanoma patients recorded by the Belgian Cancer Registry for incidence years 2009-2011.
DALYs were calculated for each American Joint Committee on Cancer stage. Parametric uncertainty in the analysis was very limited, but using pre-2010 Global Burden of Disease approaches substantially influenced results.
The findings support the hypothesis that efforts for earlier diagnosis of melanoma are important. The proportions of DALY/YLL/YLD per stage could be extrapolated to other high-income countries.
Emerging Mechanism of Action
Emerging Mechanisms of Action for Cancer Treatment
Immunotherapy Advancements
Immunotherapy has revolutionized cancer treatment with several key approaches that have emerged as critical mechanisms of action:
- Immune checkpoint inhibitors (ICIs) targeting PD-1, CTLA-4, and related pathways have become first-line clinical treatment options for certain tumors
- ICIs show great efficacy in treating immunogenic or immune hot tumors such as melanoma, kidney, and lung adenocarcinoma, though they have limited response rates to non-immunogenic cancers
- The FDA has approved PD-1/PD-L1 axis immunotherapy for PD-L1 positive cervical cancer
- Monoclonal antibodies like pembrolizumab and cetuximab target specific cancer markers
- Adoptive cell transfer methods including CAR-T cell therapy have shown potent antitumor effects both in vitro and in vivo
- Cytokine therapy such as IL-2 and tumor vaccines stimulate immune responses
Novel Molecular Targets
Recent research has identified several promising molecular targets:
- LILRB3 (Leukocyte immunoglobulin-like receptor type B) regulates differentiation and proliferation in acute myeloid leukemia
- ICAM-1 (Intercellular adhesion molecule-1) plays a bidirectional role in tumor development
- CENPN (Centromere protein N) has been identified as a potential oncogene in breast cancer and a new therapeutic target for immune checkpoint inhibitors
- PTK7 (Protein tyrosine kinase-7) has emerged as a potential therapeutic target for human tumors, with overexpression in numerous cancers
- Caldesmon has been proposed as a novel target for cancer therapy
- USP28 (ubiquitin carboxyl-terminal hydrolase 28) enables oncogenic reprogramming by regulating protein abundance of proto-oncogenes
Combination Therapies
Combination therapies have shown enhanced efficacy:
- ICIs plus tyrosine kinase inhibitors (TKI) demonstrated compelling results, with pembrolizumab plus lenvatinib showing significantly longer progression-free and overall survival in endometrial cancer patients
- ICIs plus PARP inhibitors are being investigated in ongoing studies
- HDAC6 inhibitors can increase sensitivity of cancer cells to chemotherapeutics and immune checkpoint blockade

Emerging approaches targeting cellular metabolism and epigenetic regulation include:
- N1-methyladenosine (m1A) modification affects tumor immune responses by regulating immune cells and modulating tumor microenvironment
