  "abstract": "Background and Aims Pain management remains a significant challenge in breast cancer patients, especially in cases involving chronic or postoperative thoracic pain. Conventional analgesic regimens, including opioids, may be insufficient or poorly tolerated. Ultrasound-guided regional anesthesia techniques, such as the posterior serratus plane block (PSPB), have emerged as promising adjuncts for multimodal analgesia. We report a case illustrating the effectiveness of PSPB in controlling severe thoracic pain in a patient with breast cancer.Methods A 52-year-old female patient with a history of breast cancer and thoracic wall infiltration presented with persistent, moderate-to-severe pain localized in the lateral thoracic region. Standard analgesic therapy, including opioids and adjuvant medications, failed to provide adequate relief. An ultrasound-guided PSPB was performed in the sitting position using a high-frequency linear probe. After identification of the serratus posterior muscle, 20 mL of bupivacaine 0.25% was injected between the serratus posterior and the intercostal muscles.Results The block was successfully performed without complications. The patient reported significant pain relief within 30 minutes post-procedure, with a reduction in pain score from 8/10 to 2/10 on the visual analogue scale (VAS). The effect lasted for approximately 18 hours, allowing for improved mobilization and sleep. Opioid requirements decreased substantially in the following 24 hours.Conclusions This case highlights the clinical utility of the posterior serratus plane block as a safe, simple, and effective technique for thoracic pain in breast cancer patients. It can significantly improve quality of life and reduce reliance on systemic analgesics. PSPB should be considered as part of a multimodal approach to cancer-related pain, particularly when standard treatments fail.",
