The survival impact of preoperative FOLFOX for resectable locally advanced rectal cancer: the R-NAC-01 study.

Purpose: In this follow-up of the R-NAC-01 study, we assessed the long-term oncological benefit of four courses of modified leucovorin, 5-fluorouracil (FU), and oxaliplatin (mFOLFOX6) chemotherapy before rectal surgery.

Methods: In this prospective, multicenter study (UMIN 000012559) involving 11 hospitals in Japan, patients with lower rectal cancer underwent four cycles of mFOLFOX6 chemotherapy and subsequent surgery within four to six weeks. The 3-year recurrence-free survival and local recurrence rates were then reported.

An increase in the peripheral lymphocyte-to-monocyte ratio after primary site resection is associated with a prolonged survival in unresectable colorectal carcinoma.

Purpose: The prognostic benefits of primary tumor resection in patients with unresectable distant metastatic colorectal cancer remain unclear. A high pre-treatment lymphocyte-to-monocyte ratio (LMR) was previously shown to be associated with a better prognosis. We assessed whether or not primary tumor resection was associated with an improved survival if the peripheral lymphocyte-to-monocyte ratio increased after primary site resection.

Proficiency Level of Novice Technically Qualified Surgeons in Laparoscopic Rectal Resection.

The actual proficiency levels of surgeons after their qualification by the Endoscopic Surgical Skill Qualification System have not been established. This study aimed to investigate whether technically qualified surgeons could safely perform laparoscopic low anterior resection and to evaluate the proficiency level at the time of certification acquisition. A total of 46 patients (mean age, 63.

Supervision by a technically qualified surgeon affects the proficiency and safety of laparoscopic colectomy performed by novice surgeons.

Background: The use of laparoscopic colectomy is becoming widespread and acquisition of its technique is challenging. In this study, we investigated whether supervision by a technically qualified surgeon affects the proficiency and safety of laparoscopic colectomy performed by novice surgeons.

Methods: The outcomes of 23 right colectomies and 19 high anterior resections for colon cancers performed by five novice surgeons (experience level of <10 cases) between 2014 and 2016 were assessed.

[A patient in whom oral UFT/Leucovorin therapy proved markedly effective for lung metastasis after surgery for colon cancer].

A 78-year-old male with sigmoid colon cancer underwent sigmoidectomy. The lesion was se, p1(+), n1, and Stage IV. Oral UFT therapy was performed, but was replaced with oral S-1 therapy 1 year and 6 months after surgery.

Intravenous phentolamine infusion alleviates the pain of abdominal visceral cancer, including pancreatic carcinoma.

This case report series describes eight patients (four patients with pancreatic carcinoma, one patient with hepatocellular carcinoma, one patient with gastric and rectal carcinoma, one with sigmoid colon cancer, and one with rectal cancer), whose abdominal cancer pain was treated with intravenous phentolamine infusion at 80 mg x day(-1) for 2 days. All but one of the patients had already been treated with opioids. All eight patients complained of severe abdominal pain; in five patients the pain radiated to the back, and there was associated anal pain in two patients.
