Article Synopsis
- - The study aimed to assess the effectiveness of duodenum-preserving pancreatic head resection (DPPHR) as a treatment for pancreatic neuroendocrine tumors (PNETs) in relation to curability and patient quality of life post-surgery.
- - Seven patients underwent DPPHR between January 2011 and December 2021, with the procedure showing manageable postoperative complications and achieving complete curative resections without positive tumor margins.
- - The findings suggest that DPPHR is a viable alternative to more invasive surgeries like pancreaticoduodenectomy for treating PNETs, allowing for thorough pathological assessment while minimizing patient recovery concerns.
Article Synopsis
- - A patient with sigmoid colon cancer and multiple liver metastases achieved complete remission after chemotherapy and a hepatectomy, but later experienced local recurrence and underwent a second surgery.
- - Following laparoscopic sigmoidectomy for a new adenocarcinoma diagnosed via colonoscopy, the patient received further chemotherapy which resulted in the liver metastases shrinking, allowing for a successful right hepatectomy.
- - Despite the initial success, a follow-up revealed local recurrence of liver metastasis, leading to a partial hepatectomy; the patient is currently recurrence-free and continuing treatment with modified FOLFOX.

Article Synopsis
- - A woman in her 70s with locally advanced unresectable pancreatic cancer received 5 courses of modified FOLFIRINOX chemotherapy followed by radiation therapy after being diagnosed with an irregular mass invading nearby arteries, classified as cStage Ⅲ cancer.
- - Her treatment resulted in a significant drop in CA19-9 levels, indicating a partial response to treatment, and led to the decision that her tumor was potentially curable.
- - Eight months after starting treatment, she underwent successful surgery (subtotal stomach-preserving pancreaticoduodenectomy) and was found to be cancer-free with no recurrence at 5 months post-operation.
