Randomized Controlled Trial Multicenter Study
Adjuvant PEFG (cisplatin, epirubicin, 5-fluorouracil, gemcitabine) or gemcitabine followed by chemoradiation in pancreatic cancer: a randomized phase II trial.
Information from randomized trials on the role of combination chemotherapy in the adjuvant treatment of pancreatic adenocarcinoma is limited. This randomized phase II trial aimed to identify the most promising regimen warranting phase III evaluation. ⋯ The 4-drug regimen deserves further assessment in resectable pancreatic cancer.

Up to 25% of patients with metastatic colorectal cancer (CRC) present with peritoneal carcinomatosis (PC) as the only site of metastases. Complete cytoreductive surgery (CCRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) aims for locoregional disease control and long-term survival. Oxaliplatin is effective for treating advanced CRC. This study assesses the safety and efficacy of CCRS with HIPEC with oxaliplatin for patients with PC of CRC. ⋯ CCRS followed by HIPEC with oxaliplatin for PC from CRC can be implemented with acceptable morbidity. Long-term DFS and OS can be achieved in selected patients.

Gemcitabine is a promising adjuvant treatment for patients with resected pancreatic cancer. Human equilibrative nucleoside transporter-1 (hENT1) is the major transporter responsible for gemcitabine uptake into cells. The aim of this study was to retrospectively determine the relationship between the outcome of pancreatic cancer after surgery followed by postoperative gemcitabine monotherapy and the expression of hENT1. ⋯ A high expression of hENT1 in pancreatic cancer was found to be significantly associated with a longer survival in patients who received adjuvant gemcitabine monotherapy after curative resection, and hENT1 immunohistochemistry may well serve as a significant prognostic factor for these patients.

Although postoperative adjuvant chemotherapy for pancreatic ductal adenocarcinoma (PDAC) improves survival in some patients, the effectiveness varies by individual, and the results remain unsatisfying. The aim of this study was to investigate whether intratumoral dihydropyrimidine dehydrogenase (DPD) and human equilibrative nucleoside transporter 1 (hENT1) expression can predict the survival of PDAC patients treated with adjuvant gemcitabine plus S-1 (GEM+S-1) chemotherapy. ⋯ Combined analysis of DPD and hENT1 expression predicts the survival of PDAC patients treated with adjuvant GEM+S-1 chemotherapy.

A minimum of 10 level I/II axillary nodes is recommended for accurate breast cancer staging. The goal of this study was to assess the effect of neoadjuvant chemotherapy on lymph node yield at axillary lymph node dissection. ⋯ Age, type of breast surgery, body mass index, and clinical stage have no effect on yield of lymph nodes at axillary lymph node dissection. Neoadjuvant chemotherapy, however, is associated with a far fewer nodes at axillary dissection, and alteration of the guidelines should be considered for this population of patients.
