Locally Advanced Prostate Cancer

Introduction. A locally advanced prostate cancer is defined as a malignant process spreading beyond the prostate capsule or in seminal vesicles but without distant metastasis or regional lymph nodes invasion. Clinical classification, prediction and treatment of prostate cancer. An exact staging of clinical T3 stadium is usually difficult because of the frequent over and under staging. The risk prognostic stratification is performed through nomograms and ANN (artificial neural networks). The options for treatment are: radical prostatectomy, external radiotherapy and interstitial implantation of radioisotopes, hormonal therapy by androgen blockade. Radical prostatectomy is considered in patients with T3 stage but extensive dissection of lymph nodes, dissection of neurovascular bundle (on tumor side), total removal of seminal vesicle and sometimes resection of bladder neck are obligatory. Postoperative radiotherapy is performed in patients with invasion of seminal vesicles and capsular penetration or with prostate specific antigen value over 0.1 ng/ml, one month after the surgical treatment. Definitive radiotherapy could be used as the best treatment option considering clinical stage, Gleason score, age, starting prostate specific antigen (PSA) value, concomitant diseases, life expectancy, quality of life, through multidisciplinary approach (combined with androgen deprivation). Hormonal therapy in intended for patients who are not eligible for surgical treatment or radiotherapy. Conclusion. Management of locally advanced prostate cancer is still controversial and studies for better diagnosis and new treatment modalities are ongoing.

New Biomarkers

Up to 30–50% of patients with locally advanced prostate cancer (PCa) undergoing radiotherapy (RT) experience biochemical recurrence (BCR). The immune system affects the RT response. Immunogenetics could define new biomarkers for personalization of PCa patients’ treatment. The aim of this study is to define the immunogenetic biomarkers of 10 year BCR (primary aim), 10 year overall survival (OS) and 5 year BCR (secondary aims). In this mono-institutional retrospective study, 549 Caucasian patients (a discovery set n = 418; a replication set n = 131) were affected by locally advanced PCa and homogeneously treated with RT. In the training set, associations were made between 447 SNPs in 77 genes of the immune system; and 10 year BCR and 10 year OS were tested through a multivariate Cox proportional hazard model. Significant SNPs (p-value < 0.05, q-value < 0.15) were analyzed in the replication set. Replicated SNPs were tested for 5 year BCR in both sets of patients. A polymorphism in the PDL1 gene (rs4143815) was the unique potential genetic variant of 10 year BCR (training set: p = 0.003, HR (95% CI) = 0.58 (0.41–0.83); replication set: p = 0.063, HR (95% CI) = 0.52 (0.26–1.04)) that was significantly associated with 5 year BCR (training set: p = 0.009, HR (95% CI) = 0.59 (0.40–0.88); replication set: p = 0.036, HR (95% CI) = 0.39 (0.16–0.94)). No biomarkers of OS were replicated. rs4143815-PDL1 arose as a new immunogenetic biomarker of BCR in PCa, giving new insights into the RT/immune system interaction, which could be potentially useful in new approaches using anti-PDL1 therapies for PCa.
