[Update of guidelines of the AFSOS, SFRO, SFH, SFNCM, SFCE, GFRP for the management of radio-induced nausea and vomiting].

BACKGROUND

Radiation-induced nausea and vomiting have mutiple clinical consequences: delay or refusal of irradiation (decreased antineoplastic efficacy of irradiation), altered quality of life, dehydration, malnutrition, interruption of treatment, decompensation of comorbidities and aspiration. These guidelines aim at defining good clinical practices for management of radiation-induced nausea and vomiting (RINV).

METHODS

AFSOS, SFRO, SFH, SFNEP, SFCE and GFRP applied an expert consensus methodology to propose updated guidelines.

RESULTS

RINV are underdiagnosed and undertreated. Assessment of the emetogenic risk depends on two main factors: 1) the irradiated anatomical localization and 2) the associated concomitant chemotherapy. In case of exclusive radiotherapy, primary antiemetic prophylaxis depends on the emetogenic risk of irradiated anatomical localization. Primary antiemetic prophylaxis is initiated at the onset of irradiation and continues until 24h after the end of the irradiation. In the case of concomitant radiochemotherapy, the emetogenic risk is generally higher for chemotherapy and the primary antiemetic prophylaxis corresponds to that of chemo-induced nausea and vomiting. In the case of persistence of these symptoms, subject to a well-conducted treatment, a rigorous diagnostic procedure must be carried out before being attributed to radiotherapy and precise evaluation of their impact. Remedial treatments are less well codified.

CONCLUSION

It is essential to know and good management practices for radiation-induced nausea and vomiting.
