Published: August 2022

Objective: To report the treatment and clinical monitoring in patients with prostatic evanescent carcinoma at Hospital Carlos Andrade Marin.

Methods: We reviewed the medical records of 148 patients undergoing by robot-assisted radical prostatectomy in Carlos Andrade Marin hospital. The cases reported between January 2016 to December 2018. The diagnosis was carried by taking a transrectal prostate biopsy with 12 cylinders. This samples are studied by the pathologist who reviews the radical prostatectomy surgery.

Results: Three patients had prostatic evanescent carcinoma, which those cases showed Gleason 6 (3+3) prostate cancer. Two received neoadjuvant hormone therapy and the other patient presented minor tumor invasion in 1 out of 12 cylinders used during the biopsy. In the three cases, after the sample analysis, there was no residual tumor evidence. Therefore, they were classified as pT10.

Conclusions: In this study, the results obtained from the patients studied presents the incidence of prostatic evanescent carcinoma is 2%. The combination of these different factors such as clinical status, preoperative PSA, number of positive cylinders and the invasion percentage, additionally to the usage of neoadjuvant hormone therapy prior the radical prostatectomy can help to predict evanescent carcinoma of the prostate.

Article Synopsis
  • * Specific skin manifestations linked to these infections include rashes, urticaria, and conditions like serum sickness-like syndrome primarily seen with HBV, while children may experience Gianotti-Crosti Syndrome.
  • * Chronic infections with HBV and HCV may result in more severe skin issues, such as mixed cryoglobulinemia and lichen planus, emphasizing that dermatologists need to recognize these potential skin signs of viral hepatitis.

Total internal reflection fluorescence (TIRF) microscopy benefits from high-sensitivity, low background noise, low photo-toxicity and high-contrast imaging of sub-cellular structures close to the membrane surface. Although, TIRF microscopy provides high-contrast imaging it does not provide quantitative information about morphological features of the biological cells. Here, we propose an integrated waveguide chip-based TIRF microscopy and label-free quantitative phase imaging (QPI).
