[Conventional grading vs. molecular grading : Decision aids for clinical routine].

Area of Science:

• Oncology
• Pathology
• Genetics

Background:

• Histopathological grading is essential for cancer patient management and prognosis.
• Grading relies on tumor cell differentiation, proliferation, necrosis, and invasion patterns.
• Molecular analysis (immunohistochemistry, genetic/epigenetic alterations) can enhance grading information.

Purpose of the Study:

• To review the role of conventional histopathological grading in cancer.
• To explore the potential of molecular alterations in improving cancer grading.
• To assess the current clinical implications for penile cancer treatment.

Main Methods:

• Review of conventional histopathological grading parameters.
• Discussion of molecular methods (immunohistochemistry, genetic/epigenetic analysis).
• Evaluation of the applicability of advanced methods to penile cancer.

Main Results:

• Conventional grading assesses differentiation, proliferation, necrosis, and invasion.
• Molecular techniques can provide additional prognostic and predictive information.
• Individualized penile cancer therapy based on molecular data is not yet clinically established.

Conclusions:

• Histopathological grading remains vital for cancer prognosis.
• Molecular profiling holds promise for personalized cancer therapy.
• Clinical translation of molecular insights for penile cancer requires further research.
