[Two Cases of CT-Guided Radiofrequency Ablation Therapy for Pelvic Recurrence from Rectal Cancer].
We experienced 2 cases of pelvic recurrence from rectal cancer. These patients received radiofrequency ablation(RFA) therapy. Case 1 was a 76-year-old man who underwent intersphincteric resection for lower rectal cancer in October 2013. ⋯ After RFA, pain reduced, but he developed a pelvic abscess that was treated by CT-guided drainage. He underwent complete ablation for the recurrent pelvic mass 2 years after RFA but died of exacerbation of multiple lung metastases. CT-guided RFA for painful pelvic recurrence from rectal cancer can be considered a feasible and effective treatment to reduce pain.

Case Reports[A Case of Complete Response to Computed Tomography-Guided Celiac Plexus Neurolysis of Pain Associated with Postoperative Recurrence of Colon Cancer].
The patient was a man in his 40s, who had undergone laparoscopic ileocecal resection with lymph node dissection(D3)for cecal cancer in January 2012. Histopathological examination of the resected specimens had revealed StageⅡ primary tumor with subserosal invasion and positive metastasis in 1-3 regional lymph nodes(pT2[SS]n1[+]). The pathological stage was Ⅲa(fStage Ⅲa), and the tumor showed RAS gene mutation. ⋯ The patient was discharged without major complications, and the base opioid dose was gradually reduced. Since the patient did not require any rescue medication during daytime on some days, the reduction of the base opioid dose was significantly effective in improving the patient's quality of life(QOL). In patients with pain possibly caused by metastasis to the para-aortic nodes, this local therapy technique may be considered.
