Abstract Introduction: Follicular lymphoma (FL) is an indolent yet heterogeneous B-cell lymphoproliferative disorder. Most people respond to treatment well. However, a particular group of patients has a poor prognosis, and these patients are difficult to define.Patients and methods: We retrospectively analyzed FL patients treated at the University of Debrecen in the past 20 years. We investigated prognostic factors that may influence the survival of FL patients.Results: We found a standardized uptake value (SUV)max cut-off value of 9.85 at the staging PET/CT to significantly separate FL patients’ progression-free survival (PFS) (p=0.0003, HR: 0.2560, 95%CI: 0.1232-0.5318). Lymphocyte/ monocyte (Ly/Mo) ratio of 3.45 drawn at diagnosis also significantly predicted PFS (p=0.0324, HR: 1.806, 95% CI: 1.051-3.104). Combining patients’ with staging SUVmax >9.85 and Ly/Mo < 3.45 a high-risk group of FL patients can be identified (p<0.0001, HR: 0.1033, 95%CI: 0.03719-0.2868). Similarly, a significant difference was shown with a SUVmax cut-off of 3.15 at the interim PET/CT (p<0.0001, HR: 0.1535, 95%CI: 0.06329-0.3720). Combining patients with staging SUVmax >9.85 and interim SUVmax >3.15, a high-risk group of FL patients can be identified (p<0.0001, HR: 0.1037, 95%CI: 0.03811-0.2824). The PFS difference is translated into overall survival advantage (p=0.0506, HR: 0.1187, 95%CI: 0.01401-1.005).Discussion: Biological prognostic factors, such as the Ly/ Mo ratio, may improve the prognostic assessment of staging PET/CT. Nevertheless, PFS difference is translated into OS when using a combination of staging and interim SUVmax. We consider investigating additional biological prognostic factors while currently highlighting PET/CT's role in FL.

The development of tumours implies a disproportion between proliferation, growth and differentiation, which is accompanied by significant genotypic and phenotypic variations in the diseased. The scenario of multiple oncogenic effects on the inhibition of cell growth, apoptosis and maturation, on the stimulation of proliferation, on cell migration and tissue invasion, is responsible for the occurrence of tumours both in humans and in animals. The qualitative and quantitative determination of biological prognostic factors in the tissue of affected cats and dogs directly indicates a possible tumour metastasizing, and consequently also the prognosis of neoplastic disease. Monitoring of clinical and biological prognostic factors is important for therapy and prediction of tumours in humans and animals. The determination of the proliferative potential of tumour cells by immunohistochemical detection of Ki-67 and PCNA is used in grading certain tumours in cats and dogs. It is also possible immunohistochemically to prove factors of angiogenesis and numerous activating and inhibiting proteins in the tumour tissue. In addition to other histological, clinical and biological parameters, they are significant for the further prognosis and therapy of neoplastic diseases.
