Gene Variant Descriptions PTEN dec exp indicates decreased expression of the PTEN protein. However, the mechanism causing the decreased expression is unspecified.
Associated Drug Resistance

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

PTEN dec exp triple-receptor negative breast cancer predicted - sensitive Ipatasertib + Paclitaxel Phase II Actionable In a Phase II trial, Ipatasertib (GDC-0068) in combination with Abraxane (paclitaxel) resulted in improved progression free survival (6.2 vs 4.9 months) compared to placebo in triple-receptor negative breast cancer patients with low Pten expression (J Clin Oncol 35, 2017 (suppl; abstr 1009)). detail...
PTEN dec exp melanoma decreased response Pembrolizumab Clinical Study - Cohort Actionable In a clinical study, melanoma patients with PTEN expression in less than 10% of tumor cells demonstrated decreased response to anti-PD-1 antibodies, including Keytruda (pembrolizumab), compared to patients in which PTEN is present in over 10% of tumor cells (PMID: 26645196). 26645196
PTEN dec exp renal cell carcinoma no benefit Everolimus Phase II Actionable In a retrospective analysis from a Phase II clinical trial, patients with metastatic renal cell carcinoma treated with Afinitor (everolimus) had no difference in progression free survival when stratified by high expression (n=17) and low expression (n=21) of Pten (PMID: 26951309). 26951309
PTEN dec exp melanoma sensitive SAR260301 Preclinical - Cell line xenograft Actionable In a preclinical study, SAR260301 inhibited tumor growth in xenograft models of melanoma cell lines harboring PTEN deficiency (PMID: 24387221). 24387221
PTEN dec exp renal cell carcinoma no benefit GDC-0980 Phase II Actionable In a retrospective analysis from a Phase II clinical trial, patients with metastatic renal cell carcinoma treated with Apitolisib (GDC-0980) had no difference in progression free survival when stratified by high expression (n=17) and low expression (n=19) of Pten (PMID: 26951309). 26951309
PTEN dec exp Advanced Solid Tumor predicted - sensitive Pemetrexed + Sorafenib Phase I Actionable In a Phase I clinical trial, low Pten expression or lack of Pten expression was associated with better response to treatment with the combination of Alimta (pemetrexed) and Nexavar (sorafenib) in patients with advanced solid tumors (PMID: 27213589). 27213589
PTEN dec exp Advanced Solid Tumor sensitive GSK2636771 Phase Ib/II Actionable In a Phase I/II trial, GSK2636771 treatment inhibited Akt signaling, and resulted in partial response in 2% (1/53) and stable disease in 25% (13/53) of patients with PTEN-deficient advanced solid tumors (J Clin Oncol 32:5s, 2014 (suppl; abstr 2514)). detail...
PTEN dec exp melanoma decreased response Nivolumab Clinical Study - Cohort Actionable In a clinical study, melanoma patients with PTEN expression in less than 10% of tumor cells demonstrated decreased response to anti-PD-1 antibodies, including Opdivo (nivolumab), as compared to patients in which PTEN is present in over 10% of tumor cells (PMID: 26645196). 26645196
ERBB2 amp PTEN dec exp Her2-receptor positive breast cancer decreased response CDX-3379 Preclinical Actionable In a preclinical study, knockdown of PTEN expression resulted in a decreased response to treatment with CDX-3379 (KTN3379) in ERBB2 (HER2)-amplified breast cancer cells in culture (PMID: 26880266). 26880266
ERBB2 pos PTEN dec exp Her2-receptor positive breast cancer decreased response Trastuzumab Clinical Study - Cohort Actionable In a clinical study, ERBB2 (HER2)-positive breast cancer patients with PI3K pathway activation resulting from low PTEN expression and/or PIK3CA activating mutations demonstrated decreased progression-free survival following treatment with Herceptin (trastuzumab) compared to patients without PI3K pathway activation (PMID: 17936563). 17936563
PIK3CA act mut PTEN dec exp renal cell carcinoma no benefit Everolimus Phase II Actionable In a retrospective analysis from a Phase II clinical trial, patients with metastatic renal cell carcinoma treated with Afinitor (everolimus) had no difference in progression free survival when stratified by the presence (n=21) or absence (n=17) of PIK3CA activating mutations (PMID: 26951309). 26951309
