|---|---|---|---|---|---|---|---|
| PTEN positive | melanoma | sensitive | Pembrolizumab | Clinical Study - Cohort | Actionable | In a clinical study, melanoma patients with PTEN positive tumors demonstrated a decrease in tumor size when treated with Keytruda (pembrolizumab) (PMID: 26645196). | 26645196 |
| PTEN positive | melanoma | sensitive | Nivolumab | Clinical Study - Cohort | Actionable | In a clinical study, melanoma patients with PTEN positive tumors demonstrated a decrease in tumor size when treated with Opdivo (nivolumab) (PMID: 26645196). | 26645196 |
| PTEN positive | head and neck squamous cell carcinoma | predicted - sensitive | Cetuximab | Clinical Study - Cohort | Actionable | In a clinical study, high PTEN expression was associated with improved progression-free survival (HR=0.35, p=0.008) in head and neck squamous cell carcinoma patients treated with Erbitux (cetuximab) with or without Nexavar (sorafenib) (PMID: 30926065). | 30926065 |
