How would Tecentriq be useful for a lung cancer patient with PD-L1 of 1%?

Hello doctor,

My mother has been diagnosed with lung cancer and they have tested for various markers (eGFR, PD-L1, TTF, etc.). Her PD-L1 is 1% and our understanding is that FDA approved Tecentriq only for situations of PD-L1 greater than 50. The tumor is 3 by 5. Can you provide any guidance on how or why Tecentriq could be seen as useful with a PD-L at this level?

Please help.

Thank you.

Hello doctor,

Thank you for the response. Does it mean that taking the medication can still slow down the growth rate? Is it considered the first line of treatment? Is Keytruda used for the same? Is it a PD-L1 Inhibitor? Please advice me and can you provide me with more information.

Thank you.

Hi doctor,

Will life expectancy improve? For how many months or years?

Please explain.

Will taking chemotherapy and immunotherapy give better results? When Pemetrexed 500 mg and Carboplatin AUC 5 are taken together, will it improve the condition?

Can you please advise?

Thank you.

Hello doctor,

Does this treatment work for extensive or stage four patients? Do they show side effects? Please mention if this can cause a profound impact on the body.

Thank you.
