Locally advanced pancreatic cancer (LAPC) represents a unique clinical scenario in which the tumor is considered localized but unresectable due to anatomic factors. Despite a consensus against upfront surgery, no standard approach to induction therapy exists for patients with LAPC. Extended systemic therapy has shown promise in establishing tumor response and remains the standard of care. While associated with improved local control, the timing and role of radiation therapy remain in question. Following adequate response to induction chemotherapy, a safe attempt at margin-negative resection can be considered. Special attention should be given to required vascular skeletonization and/or resection with reconstruction.
局部进展期胰腺癌(LAPC)代表了一种独特的临床情况,由于解剖因素,肿瘤被认为是局部的但无法切除。尽管一致反对 upfront 手术,但对于 LAPC 患者,尚无标准的诱导治疗方法。延长全身治疗在建立肿瘤反应方面显示出了希望,并且仍然是护理标准。虽然与改善局部控制相关,但放疗的时机和作用仍存在疑问。在充分响应诱导化疗后,可以安全地尝试进行边缘阴性切除。应特别注意所需的血管骨架化和/或切除与重建。
