On histopathology there was an intense lymphocytic, perineural infiltration and focal granulomatous inflammation, around the nerve.
All surgical specimens were examined in detail for certain pathologic features including presence of extraprostatic invasion, perineural invasion, positive surgical margin, seminal vesicle invasion and Gleason score.
Demographics and clinicopathologic data, including age, sex, adjuvant chemotherapy, cancer location, vascular invasion, perineural invasion (PNI), primary tumor size, tumor differentiation, preoperative colonic obstruction/perforation, the total count of lymph nodes examined, and year of surgery were provided from chart reviews of patients with CRC from one oncology center in Turkey.

Osman et al (2013) in which prostatic adenocarcinoma cases were histologically classified into 24 cases (34.8%) of "low grade" carcinomas (with Gleason score of 6), 18 cases (26%) of "intermediate grade" carcinomas (with Gleason score of 7) and 27 cases (39%) of "high grade" carcinomas (with Gleason score of 8 and 9).23 The perineural invasion (PNI) is the presence of prostate cancer tracking around or along the nerve within the perineural space.

Instead, the mainstay of imaging is delineating the extent of the disease preoperatively, which includes evaluating deep or superficial lobe involvement, extraglandular invasion of adjacent structures, perineural invasion, and cervical lymph node metastases.
Variables in the model included age (as a continuous variable), pathologic tumor size according to TNM classification (T1, T2, T3), pathological nodal status according to TNM classification (N1, N2, N3), histologic grade, histologic type of BC (ductal, lobular and other), presence of lymphovascular and perineural invasion, hormone receptor (ER- and PgR positive and negative), HER2 status (positive and negative), TNBC, type of surgery and presence of comorbidities.
