Background
Tumor markers are currently used in the daily clinical practice particularly for the recurrence detection during the follow-up period of the cancer diseases. Tumor markers are rarely used for the diagnostic purpose or therapy monitoring
![Page 4: About OMICS International€¦ · Mola hydatidosa x chorioepitheliom HGG HCG + TK + CHrg 85% senzit. /95%spec 93% senzit. /95%spec . Optimization of the early diagnostics prostate](https://reader033.fdocuments.us/reader033/viewer/2022052615/60923eb820ec0b69af491222/html5/thumbnails/4.jpg)
Aim of study
The aim was to propose algorithms for:
optimization of the diagnostic approach of the cancer disease
optimal therapy choice and monitoring based on the serum levels of the tumor markers
therapy effect monitoring based on the serum levels of the tumor markers
Not for screening or primary diagnostics
![Page 5: About OMICS International€¦ · Mola hydatidosa x chorioepitheliom HGG HCG + TK + CHrg 85% senzit. /95%spec 93% senzit. /95%spec . Optimization of the early diagnostics prostate](https://reader033.fdocuments.us/reader033/viewer/2022052615/60923eb820ec0b69af491222/html5/thumbnails/5.jpg)
Methods & Materials/Patients
Algorithms were proposed based on the retrospective evaluation of 30 000 results of serum tumor markers from 2 000 patients in the Faculty Hospital in Pilsen during the period of 2005 – 2015
The following cancers were evaluated: breast, colorectal, lung and prostate cancer
The following markers have been evaluated: CEA, AFP, CA, CYFRA, TPA, TPS, PSA, TK, NSE, ChrA,…
during the primary diagnosis were correlated with clinical status prior to any therapy
all data related to the detailed clinical status and the disease course during the follow-up period were available in all the patients

Cancer of unknown origin
Yes - only for prediction of tumor origin
in patients suffering from a series of diseases in case of a confusing histology and imunohistochemistry Optimal tumor marker combination:
CEA, CA 15-3, CA19-9, CYFRA 21-1, NSE, Chg A
Not - for primary diagnosis Poor sensitivity and specificity for early stage of tumor
False positivity in benign disease

BIANTA software estimates what kinds of diagnoses
“unknown type and location of primary tumor, when metastases are diagnosed or there is high suspicion of cancer disease”
both (tumor and non-tumor ) it could be, including the recommendations as to what markers should be measured in addition (the physician can – in order to make the diagnosis more precise) – fill into the requisite form whether metastases has been found and where, whether there are suspected metastases, and whether there is any area where the primary tumor might be found

CRACTES software
estimates the prognosis for certain tumor diagnosis “Will clinically evident metastases develop in case
of a patient in remission by the next check-up?” the risk of development of distant metastases in the course of approx. next 3 months and their location the physician can – in order to make the prognosis more precise – fills the patient's clinical status into the requisite form:
progression, remission,
suspected progression, indeterminable, etc.

Conclusion I
The optimal diagnostic algorithms were proposed for diagnostics and therapy monitoring of the lung, breast, colorectal and prostate cancer. Selected case reports demonstrated the use of them. Clinical and economical benefit of these proposed algorithms was evaluated.
![Page 26: About OMICS International€¦ · Mola hydatidosa x chorioepitheliom HGG HCG + TK + CHrg 85% senzit. /95%spec 93% senzit. /95%spec . Optimization of the early diagnostics prostate](https://reader033.fdocuments.us/reader033/viewer/2022052615/60923eb820ec0b69af491222/html5/thumbnails/26.jpg)
Conclusions II
Multidisciplinary approach based on these algorithms will enable to use the tumor markers for the routine clinical practice much more effectively.
