Therapeutic response following KORTUC II treatment as evaluated by PET-CT examination of patient number 4 (58-year-old female with stage IV primary breast cancer). (A) PET-CT prior to induction chemotherapy with epirubicin and cyclophosphamide. Numerous lymph node and skin metastases are depicted. (B) PET-CT prior to KORTUC II treatment. With induction chemotherapy, FDG accumulation in the right breast and right axilla improved and the skin metastases disappeared. KORTUC II, Kochi Oxydol Radiation Therapy for Unresectable Carcinomas II; PET-CT, positron emission tomography-computed tomography; FDG, fluorodeoxyglucose. (C) Four months following KORTUC II treatment. FDG accumulation in the left breast and in the chest disappeared. (D) PET-CT seven months following KORTUC II treatment. FDG accumulation had not recurred on the PET-CT scan conducted (E) 16 months following KORTUC II treatment. KORTUC II, Kochi Oxydol Radiation Therapy for Unresectable Carcinomas II; PET-CT, positron emission tomography-computed tomography; FDG, fluorodeoxyglucose. PET-CT scans conducted (F) 21 months, (G) 26 months and (H) 32 months following KORTUC II treatment. KORTUC II, Kochi Oxydol Radiation Therapy for Unresectable Carcinomas II; PET-CT, positron emission tomography-computed tomography. PET-CT scans conducted (I) 38 months, (J) 49 months and (K) 64 months following KORTUC II treatment. KORTUC II, Kochi Oxydol Radiation Therapy for Unresectable Carcinomas II; PET-CT, positron emission tomography-computed tomography. PET-CT scan conducted (L) 76 months following KORTUC II treatment. FDG accumulation and recurrence of metastasis were not observed during follow-up. Prior to treatment, the size of the right breast tumor was 28 mm and the SUVmax of FDG accumulation was 8.6. The target lesion and the FDG accumulation had disappeared four months following KORTUC II treatment, as determined by a PET-CT scan. The therapeutic effect was determined to be a complete response in patient number 4. KORTUC II, Kochi Oxydol Radiation Therapy for Unresectable Carcinomas II; PET-CT, positron emission tomography-computed tomography; FDG, fluorodeoxyglucose; SUVmax, max value of the standardized uptake value.
