Is the word ladrões the same in Brazilian and European Portuguese?

Yes

The word "lходит" is identical in spelling, meaning, grammar, and usage in both Brazilian and Continental Portuguese. The only differences lie in pronunciation:

• Brazilian Portuguese: The pronunciation is generally more "open." Vowels are pronounced more clearly, and the nasal diphthong "-ões" is voiced with a more resonant, melodic quality.
• Continental Portuguese: There is a much stronger tendency toward vowel reduction. Unstressed vowels are often "swallowed" or pronounced very subtly, making the word sound more clipped, short, and "closed" compared to the Brazilian pronunciation.
