Effects of androgen deprivation therapy on elderly men with high-risk prostate cancer: PROSARC observational study.

INTRODUCTION: Prostatic carcinoma (PC) is a frequent neoplasm in elderly patients. Although androgen deprivation is associated with survival benefits, it is also related to adverse effects such as osteoporosis, frailty, or sarcopenia, which can negatively affect the patient's quality of life. This study aims to quantify and evaluate the prevalence of osteoporosis, frailty, or sarcopenia in elderly PC patients before and after androgen deprivation. We present data from an interim analysis. MATERIALS AND METHODS: PROSARC is a national (Spain) prospective observational study (May-2022-May-2025) still in progress in 2 hospitals. It includes patients with high-risk PC, aged ≥70 years, non-candidates for local treatment and scheduled to start androgen deprivation therapy. The following variables are analyzed: comorbidity, frailty (Fried frailty phenotype criteria), osteoporosis, sarcopenia (EWGSOP2), fat mass and muscle mass, before treatment and after 6 months of follow-up. RESULTS: A 6-month follow-up was completed by 12/25 included patients (mean age, 84 years), with a high baseline prevalence of pre-frailty/frailty (67.7%), sarcopenia (66.7%) and osteoporosis (25%). Treatment did not significantly alter these variables or comorbidity. We observed changes in body mass index (p=0.666), decreased mean value of appendicular muscle mass (p=0.01) and increased percentage of fat mass (p=0.012). CONCLUSION: In patients with high-risk PC, advanced age and a considerable prevalence of osteoporosis, frailty and sarcopenia, androgen deprivation (ADT; 6 months) produces decreased muscle mass without impact on the incidence of the known adverse effects of androgen deprivation.

Usefulness of neoadjuvant chemotherapy in non-metastatic muscle-invasive bladder cancer. / Utilidad de la quimioterapia neoadyuvante en el carcinoma vesical músculo invasivo no metastásico.

OBJECTIVE: We analyzed the profile of patients who were candidates for neoadjuvant chemotherapy (NACT) in stage pT2-4aN0M0, the tolerability and adherence of our cisplatin-based protocol and oncological outcomes. MATERIAL AND METHODS: Retrospective observational cohort study including patients diagnosed with muscle-invasive bladder carcinoma treated with NACT. Clinical, histopathological, therapeutic and evolutionary characteristics of the patients were analyzed. The use of NACT was evaluated by the complete response in the surgical specimen (pT0). This and other pathological factors were related to overall survival and progression-free survival. RESULTS: We included 90 patients with muscle-invasive bladder carcinoma (clinical stage T2a-T4aN0M0) who received a cisplatin-based NACT regimen between January 2011 and December 2018, prior to radical surgery. Forty percent of patients presented an adverse reaction, with a compliance with the NACT regimen of 92.2%. There were no deaths related to systemic treatment and no adverse reaction to treatment made radical cystectomy impracticable. After performing radical cystectomy, the presence of complete response (pT0) was observed in 20 patients (21%), lower stage in the surgical specimen (

Inflammatory markers as prognostic factors in metastatic castration-resistant prostate cancer. / Marcadores inflamatorios como factor pronóstico en el cáncer de próstata resistente a la castración metastásico.

INTRODUCTION: Inflammatory markers have prognostic value in various tumors due to the role of inflammatory phenomena at different stages of tumor development. The aim of this study is to demonstrate the prognostic value of these markers, as well as other clinical and analytical variables in patients with metastatic castration-resistant prostate cancer (mCRPC). MATERIAL AND METHODS: Prospective cohort study carried out on 80 patients diagnosed with mCRPC. Clinical and analytical data were collected, and the following inflammatory markers were estimated: Absolute Neutrophil Count (ANC), Neutrophil-Lymphocyte Ratio (NLR), Total Platelet Count (TPC), Platelet-Lymphocyte Ratio (PLR), Lymphocyte-Monocyte Ratio (LMR) and Systemic Inflammation Index (SII). The values of albumin, hemoglobin (Hb), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) were also determined. RESULTS: Patients with ANC>7500, NLR>3, PLR>150, LMR>3 and/or SII>535,000, presented significantly lower median survival time than the remaining patients, and TPC was the only marker which did not show a significant association. Moreover, NLR, PLR and SII were inversely correlated with survival time. Patients with hypoalbuminemia, anemia, and elevated LDH values had significantly lower median survival time. Albumin and hemoglobin were directly correlated to overall survival time. The need for analgesia was also associated with shorter survival. CONCLUSION: The values of certain inflammatory markers are associated with shorter survival time in patients with mCRPC, and their use in clinical practice can be considered to evaluate the prognosis and estimate survival.

Leukocyte and platelet counts as prognostic values of testicular germ cell tumours. / Valor pronóstico del recuento de leucocitos y plaquetas, en tumores testiculares de células germinales.

INTRODUCTION: The immune system plays an essential role in the organism's response to cancer. Several haematological markers can influence prognosis and survival of patients. The objective of this study is to determine their prognostic value in testicular germ cell tumours. MATERIAL AND METHODS: Retrospective cohort study on 164 patients with germ cell tumours. Clinical, analytical, histological and evolutionary data were collected. The absolute neutrophil and absolute platelet counts, neutrophil-lymphocyte (NLR), platelet-lymphocyte and lymphocyte-monocyte ratios were estimated at diagnosis. The association that these markers can have with the classic prognostic factors, as well as their effect on prognosis and survival, have been analysed. RESULTS: 17.7% had NLR>4 and 14.6% ANC>8000/µL. These patients presented higher percentages of residual disease and stage II-III tumours. Patients with elevated absolute neutrophil showed also higher percentages of progression and exitus. 7.3% presented absolute platelet >400000/µL. These patients obtained higher rates of residual disease, nonseminomatous and stage III tumours. 28.4% showed platelet-lymphocyte values>150. This data was associated to higher percentages of residual disease, progression, stage II and III tumours and seminomatous tumours. 83.3% had an lymphocyte-monocyte >3. These patients presented: higher tumour markers in normal range, decreased residual disease rates and higher percentages of stage I and II tumours. The mean survival time was shorter in patients with NLR>4 and absolute neutrophil >8,000/µL. The ROC curves showed significance in the prediction of progression and values of lymphocyte-monocyte >3, and prediction of survival and values NLR>4. CONCLUSION: Our results indicate that the analysed haematological markers are associated with poor prognoses at diagnosis. Therefore, their use in daily clinical practice can be a valuable tool in the diagnosis and prognosis of patients with testicular germ cell tumours.
