@client.on(events.NewMessage(incoming=True, from_users=lista_canali, pattern=list_words_to_exclude ))
async def gestione_eventi(evento):

Answer 1

You can use a manual filter

list_words_to_exclude = ["word1", "word2", "word3"]

async def filter(event):
    for word in list_words_to_exclude :
         if word in event.raw_text:
             return True
     return False
@client.on(events.NewMessage(incoming=True, from_users=lista_canali, func=filter ))
async def gestione_eventi(evento):   

Answer 2

According to the telethon docs you can simply pass in a filter callback to func parameter of events.NewMessage :

func (callable, optional)

A callable (async or not) function that should accept the event as input parameter, and return a value indicating whether the event should be dispatched or not (any truthy value will do, it does not need to be a bool).

So in your case that could be:

list_words_to_exclude = ["word1", "word2", "word3"]

# custom filter function
def filter_words(event):
    for word in list_words_to_exclude:
         if word in event.raw_text:
             return False  # do not dispatch this event 
     return True  # dispatch all other events


# pass in the filter function as an argument to the `func` parameter
@client.on(events.NewMessage(incoming=True, from_users=lista_canali, func=filter_words))
async def gestione_eventi(evento):
    # other logic here  
    ...
