Perineural invasion (PNI) is widely studied in malignant tumors, and its prognostic significance is well demonstrated in the head and neck and prostate carcinomas, but its significance in rectal cancer is controversial. Most studies have focused on evaluating mural PNI (mPNI); however, extramural PNI (ePNI) may influence the prognosis after rectal cancer resection. We evaluated the prognostic value of ePNI compared with mPNI and with non-PNI, in rectal resections after preoperative chemoradiotherapy in 148 patients with pT3 and pT4 rectal carcinomas...

Perineal nodular induration (PNI), or biker's nodule, is a rare, bothersome, pseudotumour. Herein, we describe the surgical technique used to treat a healthy cyclist who developed an enlarging PNI for five years that grew into a perineal mass. The mass prevented him from cycling due to worsening discomfort and heaviness. The PNI-associated mass was successfully removed by wide surgical excision and a local advancement flap. Subsequently, the patient resumed cycling. Histopathology report demonstrated a benign lesion with abundant ropy collagen with native smooth muscle, vessels, and rare fibroblast-like spindle cells...

BACKGROUND: Malnutrition and immunological status are associated with survival in many cancers. Prognostic nutritional index (PNI) and body mass index (BMI) are recognized immune-nutritional indices and associated with postoperative outcome in hepatocellular carcinoma (HCC) patients. However, this association is still controversial. Our aim was to determine whether the combination of PNI and BMI is better than either alone in HCC patients' prognosis. MATERIAL AND METHODS: Preoperative PNI and BMI, patient demographics, clinical and pathological data from 322 HCC patients were collected and analyzed...

Perineural invasion (PNI) has been implicated as a poor prognostic indicator in many cancers. The National Comprehensive Cancer Network recommends consideration of observation or adjuvant therapy in the presence of PNI in early colon cancer. These recommendations are based on single institutional studies that fail to evaluate PNI within the context of adjuvant chemotherapy. The US National Cancer Database (2004-2012) was reviewed for patients with node negative colon cancer, and stratified by PNI and receipt of chemotherapy...

Systematic inflammatory response markers are considered as the most informative prognostic factors in many types of cancer. However, in synchronous colorectal cancer (synCRC), the prognostic value of inflammatory markers, including prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (d-NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR), had rarely been evaluated. Thus, this present study reviewed our consecutive patients with synCRC to investigate the prognostic value of those factors...

PURPOSE: Pancreatic ductal adenocarcinoma (PDAC) is highly lethal, and several clinical trials have shown that adjuvant chemotherapy after curative resection can improve the prognosis of these patients. However, the adjuvant chemotherapy completion rate is less than satisfactory. If this rate could be increased then the overall prognosis of PDAC might be improved; however, reports addressing this problem are insufficient. To elucidate the factors, we retrospectively investigated PDAC patients...

The voltage-gated potassium channels Kv1.1 and Kv1.2 that cluster at juxtaparanodal (JXP) regions are essential in the regulation of nerve excitability and play a critical role in axonal conduction. When demyelination occurs, Kv1.1/Kv1.2 activity increases, suppressing the membrane potential nearly to the equilibrium potential of K(+), which results in an axonal conduction blockade. The recovery of K(+)-dependent communication signals and proper clustering of Kv1.1/Kv1.2 channels at JXP regions may directly reflect nerve regeneration following peripheral nerve injury...
