[Long-Term Suppression with First-Line Chemotherapy(FOLFIRI plus BV)for Peritoneal Metastasis].

A 72-year-old man underwent right hemicolectomy for transverse colon cancer(pT4aN1aM0, Stage ⅢB), after which he received adjuvant chemotherapy(capecitabine plus oxaliplatin[CAPOX])for 6 months. Three years after the first surgery, FDG-PET/CT revealed a tumor in the abdomen. He underwent a tumorectomy and adjuvant chemotherapy(CAPOX plus bevacizumab[BV])performed for 6 months. Two years after a tumorectomy, the CEA level rose again. He was diagnosed peritoneal metastasis again. A central venous(CV)port was implanted for access to the right internal jugular vein, and he received systemic chemotherapy(fluorouracil, Leucovorin, and irinotecan[FOLFIRI]plus BV)as an outpatient. One year after this recurrence, no peritoneal dissemination was detected by CT. Thereafter, total 49 courses of FOLFIRI plus BV were introduced, but chemotherapy was discontinued due to CV port-related infection. Three months later, low back pain appeared and became a diagnosis of spondylodiscitis. He had surgery, but follow-up CT performed 8 years after the first surgery detected multiple liver metastasis. It was considered necessary to take infection control measures during long-term chemotherapy.

[Three Cases of Conversion Surgery Resulted in Pathological Complete Response for Unresectable Pancreatic Cancer].

Conversion surgery(CS)post chemotherapy for unresectable pancreatic cancer is often reported recently. Although it is still controversial about adaptation of CS, it could possibly be one of the useful choices of treatment for unresectable pancreatic cancer. We report 3 cases of CS which eventually turned out to be pathological complete response.

[A Case of Jejunal Ectopic Pancreas Incidentally Found in Laparoscopic Rectal Cancer Surgery].

In laparoscopic surgery, intraabdominal examination is occasionally difficult due to restriction of operative field and palpation. This is a case report of a jejunal ectopic pancreas which was incidentally found during laparoscopic surgery. A 49-year- old male underwent endoscopic mucosal resection for a rectal polyp which pathologically resulted in 5,000 µm invasion in submucosa and lymphatic invasion. Laparoscopic low anterior resection was planned for the patient as an additional treatment. During the surgery, irregular shaped tumor-like lesion was incidentally found in jejunum which was located 30 cm distal side from the ligament of Treitz. Partial resection of jejunum was also performed for pathological diagnosis. Resected jejunal lesion was pathologically diagnosed as an ectopic pancreas of Heinrich classification type Ⅰ. Ectopic pancreas is defined as pancreatic tissue which is discontinuous to pancreas, asymptomatic in most cases, but some reported cases of pancreatitis, forming fistula or cancerous change. Reporting with some literature review.
