Abstract
in English, Portuguese

Background: Malnutrition is very prevalent in patients with gastric cancer and increases the risk of morbidity and mortality. Adductor pollicis muscle thickness (APMT) appears as an important objective, quick, inexpensive and noninvasive measure to assess the muscle compartment.

Aim: To compare APMT and other nutritional assessment methods and to correlate these methods with postoperative mortality.

Methods: Forty-four patients, 29 men and 15 women, mean age of 63±10.2 and ranging from 34-83 years, who underwent nine (20.5%) partial and 34 (77.3%) total gastrectomies due to stomach cancer (stage II to IIIa) were preoperatively assessed by Patient Generated Subjective Global Assessment (PG-SGA), anthropometry and laboratorial profile.

Results: APMT better predicted death (p<0.001) on both, dominant and non-dominant hand, and well correlated with albumin (p=0.039) and PG-SGA (p=0.007).

Conclusion: APMT clearly allowed to determine malnutrition and to predict risk of death in patients with gastric cancer.

Racional:: A desnutrição é muito prevalente em pacientes com câncer gástrico e aumenta o risco de morbidade e mortalidade. A espessura do músculo adutor do polegar (APMT) aparece como uma importante medida objetiva, rápida, barata e não invasiva para avaliar o compartimento muscular.

Objetivo:: O objetivo deste estudo foi comparar a APMT e outros métodos de avaliação nutricional e correlacionar esses métodos com a mortalidade pós-operatória.

Métodos:: Quarenta e quatro pacientes, 29 homens e 15 mulheres; média (SD) de 63 anos (10,2) e variando de 34 a 83 anos, que foram submetidos a 9 (20,5%) gastrectomias parciais e 34 (77,3%) totais por câncer de estômago (Estágio II a IIIa) e avaliados no pré operatório por Avaliação Subjetiva Global Produzida Pelo Paciente (PG-SGA), antropometria e perfil laboratorial.

Resultados:: APMT melhor predisse morte (p<0,001) em ambas mãos, dominante e não-dominante, e se correlacionou bem com albumina (p=0,039) e PG-SGA (p=0,007).

Conclusão:: APMT permitiu claramente determinar a desnutrição e prever o risco de morte em pacientes com câncer gástrico.
