NK cell infiltrate in solid tumors.
| Tumor | NK cell infiltrate: phenotype | NK cell infiltrate: size and/or location | Ref. |
|---|---|---|---|
| Lung adenocarcinoma | Reduced expression of NKp30, NKp46 | [34] | |
| Enrichment of CD56bright Perflow poorly cytotoxic NK cells | [35] | ||
|
| |||
| Non-small cell lung cancer | CD56brightCD16dim infiltrating NK cells with impaired killing capability | [36] | |
| Infiltrating CD56dim with low activating NK-rec expression and function | NKp46+ cells mainly localized at the invasive margin | [37] | |
|
| |||
| Melanoma (primary) | Moderate/low CD56+CD3− cells | [32] | |
|
| |||
| Melanoma (primary/metastases) | Low CD56+NKG2D+ NK cells | [38] | |
|
| |||
| Melanoma (metastases) | Low CD56+ NK cells | [21] | |
|
| |||
| Melanoma (nodal/skin metastases) | CD56+ NK cells rarely present in melanoma | [39] | |
|
| |||
| Melanoma (nodal metastases) | NKp30, NKG2D expression inversely correlated with number of tumor cells in the LN | NK cells surround tumor cell cluster | [40] |
|
| |||
| Melanoma (nodal metastases) | Enrichment of CD56dim KIR+CD57+ cytotoxic NK cells | [41] | |
|
| |||
| Colorectal cancer | Scarce NKp46+ infiltrating NK cells (despite high levels of chemokines) | [42] | |
|
| |||
| Colorectal cancer | Reduced NKp46, NKp30, DNAM-1 expression | [43] | |
|
| |||
| Colorectal cancer (lung metastases) | Low NKp46+ NK cell infiltrate | [44] | |
|
| |||
| Breast cancer | Expression/function of NKp30, NKG2D in infiltrating NK cells decreases with disease progression | [45] | |
|
| |||
| Breast cancer | Enrichment of CD56bright Perflow poorly cytotoxic NK cells | [35] | |
|
| |||
| Renal cell carcinoma (lung metastases) | High NKp46+ NK cell infiltrate correlates with improved survival | [44] | |
|
| |||
| GIST (GastroIntestinal Stromal Tumors) | Substantial NKp46+ NK cell infiltrate mainly surrounding tumor nests | [46] | |
|
| |||
| GIST (GastroIntestinal Stromal Tumors) | Low NK cell infiltration/high metastases at diagnosis | [46] | |
|
| |||
| GIST (GastroIntestinal Stromal Tumors) | High NK cell infiltration/prolonged progression-free survival after imatinib treatment | [47] | |
