For carcinomas without
perineural invasion, the recurrence rate is about 4.5% for standard excision and about 2.0% for CCPDMA, the analysis showed.
When we analyzed PSA values and the histopathological features (
perineural invasion, surgical margin positivity, extraprostatic spread, seminal vesicle invasion, and Gleason score) with high NLR, there was a relationship between high NLR and Gleason score.

Prognostic significance of the diameter of
perineural invasion in radical prostatectomy specimens.
The significance of
perineural invasion found on needle biopsy of the prostate: implications for definitive therapy.
The degree of SCC differentiation and
perineural invasion were not assessed.
Kaplan-Meier survival analysis was also performed for
perineural invasion, which did not show significant differences (HR of no
perineural invasion, 0.8243; 95% CI, 0.4642-1.441; p=0.4862; Figure 2C).

Perineural and N/A lymphovascular invasion Study LN Ex Chen et al.
Evaluation of the association between
perineural invasion and clinical and histopathological features of cervical cancer.
Perineural invasion was identified in 11 cases (47.82%).
For this study cohort, data regarding tumor site, tumor size, TNM classification, margin status, tumor thickness,
perineural invasion, character of the invasive front, vascular permeation, resection margins on all surfaces, postoperative RT, and re-resection after the primary surgery were described by Lawaetz and Homoe.
With the use of
perineural catheters, early discharge is provided with postoperative analgesia (5).
