Humoral complementomics - exploration of noninvasive complement biomarkers as predictors of renal cancer progression.

Despite the progress of anti-cancer treatment, the prognosis of many patients with solid tumors is still dismal. Reliable noninvasive biomarkers are needed to predict patient survival and therapy response. Here, we propose a Humoral Complementomics approach: a work-up of assays to comprehensively evaluate complement proteins, activation fragments, and autoantibodies targeting complement proteins in plasma, which we correlated with the intratumoral complement activation, and/or local production, focusing on localized and metastatic clear cell renal cell carcinoma (ccRCC). In two prospective ccRCC cohorts, plasma C2, C5, Factor D and properdin were elevated compared to healthy controls, reflecting an inflammatory phenotype that correlated with plasma calprotectin levels but did not associate with CRP or with patient prognosis. Conversely, autoantibodies against the complement C3 and the reduced form of FH (a tumor neo-epitope reported in lung cancer) correlated with a favorable outcome. Our findings pointed to a specific group of patients with elevated plasma C4d and C1s-C1INH complexes, indicating the initiation of the classical pathway, along with elevated Ba and Bb, indicating alternative pathway activation. Boostrapped Lasso regularized Cox regression revealed that the most predictive complement biomarkers were elevated plasma C4d and Bb levels at the time of surgery, which correlated with poor prognosis. In conclusion, we propose Humoral Complementomics as an unbiased approach to study the global state of the complement system in any pathological plasma sample and disease context. Its implementation for ccRCC revealed that elevated C4d and Bb in plasma are promising prognostic biomarkers, correlating with shorter progression-free survival.

External validation of an algorithm to personalize nerve sparing approaches during robot-assisted radical prostatectomy in men with unilateral high-risk prostate cancer.

Limited evidence exists about preserving neurovascular bundles during radical prostatectomy (RP) for high-risk prostate cancer (HRPCa) patients. Hence, we validated an existing algorithm predicting contralateral extraprostatic extension (cEPE) risk in unilateral high-risk cases. This algorithm aims to assist in determining the suitability of unilateral nerve-sparing RP. Among 264 patients, 48 (18%) had cEPE. The risk of cECE varied: 8%, 17.2%, and 30.8% for the low, intermediate, and high-risk groups, respectively. Despite a higher risk of cECE among individuals classified as low-risk in the development group compared to the validation group, our algorithm's superiority over always/never nerve-sparing RP was reaffirmed by decision curve analysis. Therefore, we conclude that bilateral excision may not always be justified in men with unilateral HRPCa. Instead, decisions can be based on our suggested nomogram.

An updated model for predicting side-specific extraprostatic extension in the era of MRI-targeted biopsy.

PURPOSE: Accurate prediction of extraprostatic extension (EPE) is pivotal for surgical planning. Herein, we aimed to provide an updated model for predicting EPE among patients diagnosed with MRI-targeted biopsy. MATERIALS AND METHODS: We analyzed a multi-institutional dataset of men with clinically localized prostate cancer diagnosed by MRI-targeted biopsy and subsequently underwent prostatectomy. To develop a side-specific predictive model, we considered the prostatic lobes separately. A multivariable logistic regression analysis was fitted to predict side-specific EPE. The decision curve analysis was used to evaluate the net clinical benefit. Finally, a regression tree was employed to identify three risk categories to assist urologists in selecting candidates for nerve-sparing, incremental nerve sparing and non-nerve-sparing surgery. RESULTS: Overall, data from 3169 hemi-prostates were considered, after the exclusion of prostatic lobes with no biopsy-documented tumor. EPE was present on final pathology in 1,094 (34%) cases. Among these, MRI was able to predict EPE correctly in 568 (52%) cases. A model including PSA, maximum diameter of the index lesion, presence of EPE on MRI, highest ISUP grade in the ipsilateral hemi-prostate, and percentage of positive cores in the ipsilateral hemi-prostate achieved an AUC of 81% after internal validation. Overall, 566, 577, and 2,026 observations fell in the low-, intermediate- and high-risk groups for EPE, as identified by the regression tree. The EPE rate across the groups was: 5.1%, 14.9%, and 48% for the low-, intermediate- and high-risk group, respectively. CONCLUSION: In this study we present an update of the first side-specific MRI-based nomogram for the prediction of extraprostatic extension together with updated risk categories to help clinicians in deciding on the best approach to nerve-preservation.

Recurrent Gleason Score 6 Prostate Cancer After Radiotherapy or Ablation: Should We Observe Them All? Results from a Large Multicenter Salvage Radical Prostatectomy Consortium.

BACKGROUND: Salvage radical prostatectomy (sRP) yields poor functional outcomes and relatively high complication rates. Gleason score (GS) 6 prostate cancer (PCa) has genetic and clinical features showing little, if not absent, metastatic potential. However, the behavior of GS 6 PCa recurring after previous PCa treatment including radiotherapy and/or ablation has not been investigated. OBJECTIVE: To evaluate the oncological outcomes of sRP for radio- and/or ablation-recurrent GS 6 PCa. DESIGN, SETTING, AND PARTICIPANTS: Retrospective data of sRP for recurrent PCa after local nonsurgical treatment were collected from 14 tertiary referral centers from 2000 to 2021. INTERVENTION: Prostate biopsy before sRP and sRP. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A survival analysis was performed for pre-sRP biopsy and sRP-proven GS 6. Concordance between PCa at pre-sRP biopsy and sRP histology was assessed. RESULTS AND LIMITATIONS: We included GS 6 recurrent PCa at pre-sRP biopsy (n = 142) and at sRP (n = 50), as two cohorts. The majority had primary radiotherapy and/or brachytherapy (83.8% of GS 6 patients at pre-sRP biopsy; 78% of GS 6 patients at sRP) and whole-gland treatments (91% biopsy; 85.1% sRP). Biopsy GS 6 10-yr metastasis, cancer-specific survival (CSS), and overall survival (OS) were 79% (95% confidence interval [CI] 61-89%), 98% (95-99%), and 89% (78-95%), respectively. Upgrading at sRP was 69%, 35.5% had a pT3 stage, and 13.4% had positive nodes. The sRP GS 6 10-yr metastasis-free survival, CSS, and OS were 100%, 100%, and 90% (95% CI 58-98%) respectively; pT3 and pN1 disease were found in 12% and 0%, respectively. Overall complications, high-grade complications, and severe incontinence were experienced by >50%, >10%, and >15% of men, respectively (in both the biopsy and the sRP cohorts). Limitations include the retrospective nature of the study and absence of a centralized pathological review. CONCLUSIONS: GS 6 sRP-proven PCa recurring after nonsurgical primary treatment has almost no metastatic potential, while patients experience relevant morbidity of the procedure. However, a significant proportion of GS 6 cases at pre-sRP biopsy are upgraded at sRP. In the idea not to overtreat, efforts should be made to improve the diagnostic accuracy of pre-sRP biopsy. PATIENT SUMMARY: We investigated the oncological results of salvage radical prostatectomy for recurrent prostate cancer of Gleason score (GS) 6 category. We found a very low malignant potential of GS 6 confirmed at salvage radical prostatectomy despite surgical complications being relatively high. Nonetheless, biopsy GS 6 was frequently upgraded and had less optimal oncological control. Overtreatment for recurrent GS 6 after nonsurgical first-line treatment should be avoided, and efforts should be made to increase the diagnostic accuracy of biopsies for recurrent disease.

Unilateral Pelvic Lymph Node Dissection in Prostate Cancer Patients Diagnosed in the Era of Magnetic Resonance Imaging-targeted Biopsy: A Study That Challenges the Dogma.

PURPOSE: Bilateral extended pelvic lymph node dissection at the time of radical prostatectomy is the current standard of care if pelvic lymph node dissection is indicated; often, however, pelvic lymph node dissection is performed in pN0 disease. With the more accurate staging achieved with magnetic resonance imaging-targeted biopsies for prostate cancer diagnosis, the indication for bilateral extended pelvic lymph node dissection may be revised. We aimed to assess the feasibility of unilateral extended pelvic lymph node dissection in the era of modern prostate cancer imaging. MATERIALS AND METHODS: We analyzed a multi-institutional data set of men with cN0 disease diagnosed by magnetic resonance imaging-targeted biopsy who underwent prostatectomy and bilateral extended pelvic lymph node dissection. The outcome of the study was lymph node invasion contralateral to the prostatic lobe with worse disease features, ie, dominant lobe. Logistic regression to predict lymph node invasion contralateral to the dominant lobe was generated and internally validated. RESULTS: Overall, data from 2,253 patients were considered. Lymph node invasion was documented in 302 (13%) patients; 83 (4%) patients had lymph node invasion contralateral to the dominant prostatic lobe. A model including prostate-specific antigen, maximum diameter of the index lesion, seminal vesicle invasion on magnetic resonance imaging, International Society of Urological Pathology grade in the nondominant side, and percentage of positive cores in the nondominant side achieved an area under the curve of 84% after internal validation. With a cutoff of contralateral lymph node invasion of 1%, 602 (27%) contralateral pelvic lymph node dissections would be omitted with only 1 (1.2%) lymph node invasion missed. CONCLUSIONS: Pelvic lymph node dissection could be omitted contralateral to the prostate lobe with worse disease features in selected patients. We propose a model that can help avoid contralateral pelvic lymph node dissection in almost one-third of cases.

Diagnostic accuracy and clinical utility of micro-ultrasound guided biopsies in patients with suspected prostate cancer.

Introduction: New technologies to improve quality of prostate biopsies are appearing in clinical practice.We evaluate the performance of a micro-ultrasound device and the Prostate Risk Identification using MicroUltraSound (PRI-MUS) score in detecting clinically significant prostate cancer (csPCa). Material and methods: We retrospectively reviewed data of 139 biopsy- naïve patients with suspicion of prostate cancer, who underwent diagnostic MRI and micro-ultrasonography (microUS), followed by transrectal prostatic biopsy (systematic ±targeted) under local anesthetic. The main objective was to evaluate the performance of the Prostate Risk Identification using MicroUltraSound (PRI-MUS) score in detecting csPCa, defined as International Society of Urological Pathology (ISUP) ≥2. Results: Of all patients, 97 (70%) were found to have PCa, and 62 (45%) having csPCa.Among 100 patients with positive microUS (PRI-MUS score ≥3), 23 (23%) had ncsPCa and 57 (57%) were diagnosed with csPCa (ISUP ≥2); and in 39 patients with negative microUS, 12 (31%) were diagnosed with ncsPCa and 5 (13%) with csPCa.A PRI-MUS score ≥3 presented a sensitivity, specificity, positive predictive value and negative predictive value of 92%, 44%, 57% and 95%, respectively, for the detection of csPCa.The PRI-MUS score had higher areas under the curve than Prostate Imaging Reporting & Data System (PI-RADS) both for targeted (AUC 0.801 vs 0.733) and systematic + targeted (AUC 0.776 vs 0.694) biopsies for csPCa detection. Conclusions: In our cohort, microUS performed well as a diagnostic tool through an easily implementable scale. MicroUS presented similar sensitivity and higher specificity than MRI in detecting csPCa. Further multicenter prospective studies may clarify its role in prostate cancer diagnosis.

Accuracy of PET-choline in nodal staging of localized very high-risk prostate cancer.

OBJECTIVES: Localized very high-risk prostate cancer (VHR PCa) has long suffered from the inex-istence of good lymph node staging methods other than invasive surgery, as computed tomogra-phy has low sensitivity for nodal disease. With the rising use of positron emission tomography (PET), it is clinically meaningful to know its value for these patients. Our goal was to evaluate the real-life diagnostic accuracy of PET Choline in nodal staging, comparing it with the gold standard of extended pelvic lymph node dissection (ePLND). MATERIALS AND METHODS: We reviewed data from a high-volume center, including patients with VHR PCa according to current NCCN guidelines who underwent community 18F-fluorocholine PET/CT; followed by ro-botic assisted laparoscopic prostatectomy (RALP) and ePLND between 2010 and 2021. RESULTS: We included 44 patients and 88 lymph node regions. Among those, 14/44 (31.8%) patients and 20/88 (22.7%) regions had nodal disease present on definitive pathology. In comparison with ePLND, we found a sensitivity of 64.3% (95% CI, 39.2-89.4%), specificity of 83.3% (95% CI, 70.0- 96.7%), PPV of 64.3% (95% CI, 39.2-89.4%), and NPV of 83.3% (95% CI, 70.0-96.7%) for nodal disease on a patient-based analysis; and sensitivity of 35.0% (95% CI, 14.1-60.0%), specificity of 88.2% (95% CI, 80.6-95.9%), PPV of 46.7% (95% CI, 21.4-71.9%), and NPV of 82.2% (95% CI, 73.4-91.0%) on a region-based analysis. CONCLUSIONS: In our view 18F-fluorocholine PET/CT doesn't meet the criteria to be a standard exam for pre-operative staging for patients with VHR PCa, mostly due to its low sensitivity. However, other radiotracers should continue to be investigated in this setting.

Medium-term oncological outcomes of intermediate-risk prostate cancer treated with HIFU or cryotherapy. A single center 10-year experience.

OBJECTIVES: Focal therapies (FTs) are promising techniques for the treatment of localized prostate cancer. We assessed the medium-term oncological outcomes of intermediate-risk prostate cancer (PCa) treated with HIFU or cryotherapy. MATERIALS AND METHODS: One-hundred and fifty consecutive patients with intermediate-risk PCa, treated between 2009 and 2018 at a single center were included. Primary study outcome was failure-free survival (FFS), defined as absence of additional treatment, systemic progression or prostate cancer related death. RESULTS: Thirty-seven (25%) patients underwent cryotherapy and 113 (75%) HIFU. Median age was 69 (IQR 62-72) years, with 36 (24%) presenting palpable disease on rectal examination, and median total PSA of 7.85 (IQR 5.75-10.62) ng/mL. Patients were followed for a median of 61 (IQR 48-82) months. FFS at 2 and 4 years was of 75.6% and 53.6%, respectively. Survival from whole gland or systematic treatment at 2 and 4 years was of 78.9% and 53.9%, respectively. Patients with FFS presented lower total PSA nadir (1.89 vs 3.25 ng/mL, p < 0.001), higher % PSA reduction at 3 months (66.1% vs 49.3%, p < 0.001), and at nadir (75.5% vs 55.8%, p < 0.001). Other characteristics such has the treatment modality, age, prostate size, initial total PSA, cT stage, International Society of Urological Pathology (ISUP), tumor location and biopsy results by region did not differ between patients failing and not failing FT. Complications were uncommon (13%), with only onr (1%) patient having Clavien-Dindo grade > II. No deaths due to treatment were registered. CONCLUSIONS: At medium-term, FTs for intermediate-risk PCa presented good oncological results, with an excellent safety profile.

[Long term results of congenital penile curvature treated with cavernosa corpora rotation.] / Seguimiento a largo plazo de la incurvación peneana congénita tratada mediante rotación de los cuerpos cavernosos.

INTRODUCTION: Congenital penile curvature (PCC) is a disorder caused by an alteration in the embryonic development of the urethra and the corporacavernosa, which causes difficulty in penetration, requiring surgical correction when inter course is impossible. OBJECTIVE: To analyze the results of the surgical treatment of the IPC by means of rotation of the corpora cavernosa (RCC) described and modified by Shaeer. PATIENTS AND METHODS: Ten patients diagnosed with PCC with impossibility to inter course, were operated in a period of 36 months. Prior to the intervention,we applied the IIEF-5 questionnaire, measured the length of the penis and the angle of curvature throughself-photographs in three projections. By subcoronal approach,we perform denudation of the penis. On both sides of the urethra we incised Buck's fascia and released the neurovascular bundle from the ventral to the dorsal side. We generate an artificial erection evidencing the curvature. On the dorsal aspect of both corpora cavernosa, we made two incisions in the external longitudinal layer of the tunica albuginea. We sutured the internal and external edges of both incisions together with a 4/0 non-reabsorbable monofilament continuous suture, checking the correction of the curvature by means of an artificial erection. The patients were discharged the day after the intervention. The penile length and curvature were determined in the sixth month, and the IIEF-5 questionnaire. For the comparison of means we used the Mann-Whitney U test.  RESULTS: The mean age was 26.8 years. The average follow-up was 20.7 months (12-31) and the median was 24. Before the intervention, the average curvature was 68.5° (50-90°); the average length 14.2 cm (10-18) and the IIEF-5 of 21. After surgery, the average length was 13.7 cm, the residual curvature the IIEF-5 of 25. There were no statistically significant differences between pre and postoperative penile length,(p=0.08). Nine patients assured that they would under go the same intervention again. CONCLUSIONS: RCC is an effective therapeutic alternative to the techniques of plication or lengthening of the tunica albuginea for the treatment of PCC, main tainingits long-term results.

En la cara dorsal deambos cuerpos cavernosos realizamos dos incisiones longitudinales en la capa longitudinal externa de la túnica albugínea. Suturamos los bordes internos y externosde ambas incisiones entre sí con una sutura continuade monofilamento irreabsorbible de 4/0, comprobando mediante una erección artificial la corrección de la incurvación. Los pacientes fueron dados de alta al día siguiente de la intervención. Al sexto mes se determinaron la longitud e incurvación peneanas, y el cuestionario IIEF-5. Para la comparación de medias utilizamos el test de la U de Mann-Whitney. RESULTADOS: La edad media fue 26,8 años. El seguimiento promedio fue 20,7 meses (12-31) y la mediana 24. Antes de la intervención la incurvación media fue 68,5° (50-90°); la longitud media 14,2 cm (10-18) yel IIEF-5 de 21. Tras la intervención la longitud media fue 13,7 cm, la incurvación residual 25. No existieron diferencias estadísticamente significativas entre la longitud peneana pre y postquirúrgica,(p=0,08). Nueve pacientes aseguraron que volverían asometerse a la misma intervención. CONCLUSIONES: La RCC constituye una alternativa terapéutica eficaz a las técnicas de plicatura o alargamiento de la túnica albugínea para el tratamiento de la IPC, manteniendo sus resultados a largo plazo.
