ABSTRACT
BACKGROUND: Breast cancer is the most commonly occurring cancer among women. Among its treatment sequelae is chronic neuropathic pain after breast surgery (CNPBS). Pain management is difficult and classicaly consists in a pharmacological approach, however recent studies have advocated the use of locoregional techniques as adjuvants. Serratus plane block (SPB) has recently emerged as a potential tool for the control of CNPBS. This study aims to evaluate the efficacy and potencial role of the ultrasound-guided SPB on CNPBS.
METHODS: A retrospective analysis was performed on 30 patients with CNPBS refractory to drug therapy, who underwent SPB between 2017-2019. The following parameters were analyzed: basal pain, pain at 24 h, 1 week and at 1 month. The Mann-Whitney test was applied. Statistical significance was considered at the level of p < 0.05. All statistical analysis was performed with SPSS 20.
RESULTS: 3 patients were excluded. At 24 h, we report pain improvement (at least 30% reduction on basal pain score) on 20 patients and after 1 week on 12. At 1 month after, 22 patients had improved, from these: 11 improved with no therapeutic adjustment; 11 patients improved with therapeutic adjustment (8 in gabapentinoid monotherapy, 3 with introduction of polytherapy). 5 patients didn’t improve.
CONCLUSION: Our study demonstrated SPB as a valid alternative for CNPBS management when pharmacologic therapy has been proven insufficient, with no side effects reported. Randomized studies are needed to assess the magnitude of SPB on CNPBS and to identify the patients who benefit the most from SPB.
