What this trial studies

This study investigates the role of TLR4+ blood cells in patients diagnosed with various types of solid cancers. It aims to understand how these immune cells can be activated to enhance the effectiveness of immunotherapy, particularly in patients who have not previously received immune checkpoint inhibitors. Participants will undergo blood sampling to analyze the characteristics and behavior of these cells in relation to their cancer treatment. The study includes patients with both metastatic and resectable tumors, focusing on those who are initiating immunotherapy.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with a histologically confirmed diagnosis of solid tumors who are either starting immunotherapy or are eligible for surgery.

Not a fit: Patients with secondary malignancies or those who have received prior anticancer treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this research could lead to improved immunotherapy strategies for patients with solid tumors, potentially increasing their treatment options and outcomes.

How similar studies have performed: While the approach of examining TLR4+ cells in cancer patients is relatively novel, previous studies have shown promise in utilizing immune system activation for cancer treatment.

Eligibility criteria

Inclusion criteria specific to cohort 1:

\- Patient with metastatic disease or unresectable locally advanced malignancy (solid tumors) who is naive of immune checkpoint inhibitors (ICI)-based immunotherapy and is due to initiate an ICI immunotherapy alone or in combination with any other systemic anticancer treatment.

Inclusion criteria specific to cohort 2:

\- Patient with a diagnosed malignancy amenable to surgery with curative intent who is naive of any anticancer treatment

Exclusion Criteria:

* Patient with secondary malignancy unless this malignancy is cured with no evidence of recurrence for at least 5 years.
