ABSTRACT
Prostate cancer is a common malignant tumor in male genitourinary system, and radical prostatectomy is one of the important methods to treat prostate cancer. Indocyanine green is a non-radioactive, water-soluble compound, which can help identify anatomical structures and visualize blood vessels through near-infrared fluorescence. The role and injection techniques of Indocyanine green in radical prostatectomy in sentinel lymph node identification, pelvic lymph node dissection and neurovascular bundle preservation are reviewed, so as to provide a reference for improving the surgical effect, reducing the difficulty of surgery, and prolonging the survival period of patients, and evaluate the potential research field of this technology in the future.
ABSTRACT
Retzius-sparing robot assisted radical prostatectomy (RS-RARP) can significantly improve the immediate urinary continence without increasing the positive rate of surgical margin.However, the learning curve is long, and fewer than 10% of the surgeons can master it.Therefore,we have optimized the procedures of RS-RARP, applying radical prostatectomy with retrograde release of neurovascular bundle to preserve it to the maximum extent.Urethral anastomosis can be performed with only one suture, which eliminates the need for Hem-o-lok and reduces subsequent complications.Our team routinely carries out this operation, and conlcudes that this surgical method can achieve good tumor control, good urinary continence, fast recovery of sexual function, few complications, and strong operability.This article details the key steps and operation experience of this technique.
ABSTRACT
【Objective】 To explore the effectiveness and safety of different salvage therapies for local recurrence of tumor following primary prostate cryoablation so as to provide the reference for the treatment of prostate similar cases. 【Methods】 The clinical data of patients with prostate cancer (cT1c-4N0M0) who received salvage therapy for local recurrence of tumor following primary prostate cryoablation in the Sun Yat-Sen University Cancer Center during June 2014 and Dec. 2020 were retrospectively analyzed. Salvage therapies included local therapy (salvage radiotherapy, salvage cryoablation or salvage radical prostatectomy) and androgen deprivation therapy (ADT). 【Results】 Altogether 8 patients were involved. The median age was 71(63-76) years, the median prostate specific antigen (PSA) at the first diagnosis was 17.650(10.380-325.100) ng/mL, the median nadir post-cryoablation PSA was 0.041(0.003-0.541) ng/mL, and the median PSA at local recurrence was 3.030(2.090-19.180) ng/mL. Abnormal digital rectal examination was found in 3 cases, and radiographic evidence of local recurrence was found in 7 cases. Prostate biopsy was performed in 4 cases, 2 of which had positive results. The median follow-up after salvage therapy lasted for 54 (9-75) months. Four cases received salvage radiotherapy, 2 of which developed bloody stool, hematuresis and urinary tract infection, and recovered after conservative treatment; 1 case received salvage cryoablation without side effects; 1 case underwent radical prostatectomy and radiotherapy, developed lymphorrhagia and recovered after conservative treatment; 2 cases received ADT alone, one experienced hot flashes and recovered after conservative treatment, and the other progressed into castration-resistant prostate cancer after 63 months. No other progression or death occurred at the termination of follow-up. 【Conclusion】 Salvase therapy (salvage radiotherapy, salvage cryoablation, salvage radical prostatectomy) and ADT can be used for local recurrence of tumor following primary prostate cryoablation. However, large-scale prospective research is needed to confirm the effectiveness and safety of different therapies.
ABSTRACT
With the development of minimally invasive technology, robot-assisted laparoscopic radical prostatectomy (RARP) has become the main method and gold standard in the treatment of organ-localized prostate cancer. After previous exploration of various surgical approaches and surgical methods in our center, we first proposed the modified (port-free) single-site RARP (pf-ssRARP), which has been proved safe and feasible by theoretical verification and practical operation. The technique has certain advantages in postoperative rehabilitation, urinary control recovery, sexual function improvement, incision cosmetics and social economics. In this paper, the key steps of this technique are introduced and illustrated in detail.
ABSTRACT
【Objective】 To explore the learning curve of single-surgeon robot-assisted laparoscopic radical prostatectomy (RARP), which provides a reference for physicians who intend to carry out RARP. 【Methods】 The clinical data of 65 prostate cancer patients who underwent RARP in our hospital during Sep.2022 and Dec.2023 were retrospectively analyzed.The patients’ median age was 67.5(58.1-82.4) years, median total prostate-specific antigen (PSA) was 15.6 (6.7-98.4) ng/mL, median body mass index (BMI) was 20.8(17.4-27.3) and preoperative clinical stage of tumor was T2aN0M0-T3bN1M0.The cumulative sum (CUSUM) method was used to fit the learning curves of machine installation time and operation time.According to the inflection points, the learning curves were divided into different learning stages, and the clinical data of patients at different learning stages were compared. 【Results】 The learning curve of RARP was 12 cases.The 65 cases were divided into three stages: 1st-12th cases in the learning stage, 13rd-43rd cases in the mastery stage, and 44th-65th cases in the proficiency stage.With the increase of the number of surgical cases, the median operation time [191(100-360) min vs. 116(83-165) min vs. 90(75-105) min] and median intraoperative blood loss [403(180-900) mL vs. 236(180-305) mL vs. 94(30-200) mL] in the three stages showed a gradual downward trend (P<0.05).The median machines installation time of the learning stage was significantly longer than that in the mastery stage and the proficiency stage [25(21-28) min vs. 12(11-15) min vs. 12(11-14) min] (P<0.05).The positive surgical marginrate (PSM) in the learning stage was significantly higher than that in the mastery stage and proficiency stage (41.7% vs.22.6% vs.22.7%) (P<0.05). 【Conclusion】 For surgeons with rich experience in traditional laparoscopic surgery, the learning curve of RARP is about 12 cases, and after 43 cases, the operation time and intraoperative blood loss can be further reduced.
ABSTRACT
【Objective】 To investigate the effects of radical prostatectomy (RP) or brachytherapy (BT) on the prognosis of patients with high-risk prostate cancer as initial treatment, in order to provide a reference for the selection of clinical treatment options. 【Methods】 The clinical data of 133 191 patients diagnosed with high-risk prostate cancer and treated with RP or BT during 2005 and 2014 were extracted from the SEER database.The 5-year and 10- year cancer-specific survival (CSS) and overall survival (OS) were compared with K-M analysis and univariate and multivariate Cox regression.The clinical data of another 253 patients diagnosed with high-risk prostate cancer in Subei People’s Hospital during 2015 and 2020 were collected, including 153 patients who received RP and 100 patients who received BT.The 5-year biochemical progress-free survival (bPFS) and CSS were compared with K-M analysis. 【Results】 Univariate analysis of SEER data showed that BT was associated with a higher risk of death (HR=1.319, 95%CI: 1.256-1.386, P<0.001); age, marital status and TNM stage were associated with higher risk of death (P<0.001).Multivariate analysis, adjusted for relevant variables, showed that BT did not result in a higher risk of death compared with RP (HR=0.964, 95%CI:0.924-0.996, P=0.808). The OS curve showed that the longer the observed survival time, the better OS of RP as compared to BT (P<0.001); however, the CSS survival curve showed that the longer the observed survival time, the better CSS of BT compared to RP (P<0.001).The single-center data analysis showed no significant difference between BT and RP in the 5-year bPFS (P=0.263) and CSS (P=0.946). 【Conclusion】 For patients with high-risk prostate cancer, there is a significant difference in the prognosis of the two treatments if there is no adjustment of age, marital status, TNM stage and other factors, and the efficacy of RP is better than that of BT, especially in patients with survival more than 10 years.However, there is no statistically significant difference in the prognosis after the possible confounding factors are adjusted.Therefore, the initial treatment choice for these patients should be weighed from multiple perspectives, and patients’ choices must be respected after they are fully informed.
ABSTRACT
【Objective】 To introduce a surgical technique modified by our center, the establishment of a robot-assisted radical prostatectomy (RARP) channel with extraperitoneal three-port method, and discuss its methods, skills, safety and efficacy. 【Methods】 Clinical data of 21 patients with early and intermediate prostate cancer treated with this surgery during Aug.2022 and Jun.2023 were retrospectively analyzed.Surgical time, intraoperative bleeding volume, postoperative complications, drainage tube retention time, postoperative hospital stay, and follow-up results were observed. 【Results】 All 21 cases of surgery were successfully completed by the same surgeon, without peritoneal rupture or addition of auxiliary holes.The time to establish the extraperitoneal gap and install robotic arm was 20.2 (16.0-28.0) min, the operation time was 107.0(60.0-161.0) min, the amount of intraoperative bleeding was 52.8 (31.0-121.0) mL.All patents resumed eating and drinking the next day after operation.The drainage tube indwelling time was 3.9 (2.0-6.0) d, and the postoperative hospital stay was 4.9 (3.0-7.0) d.No serious complications occurred.The urinary catheter was removed 10 days after operation.One month after operation, 20 patients (95.2%) achieved satisfactory urinary control.The postoperative pathology was prostate adenocarcinoma in all cases, with negative margins, and the prognostic grouping of ISUP was 2 cases in group 1, 6 cases in group 2, 10 cases in group 3, 2 cases in group 4, and 1 case in group 5. 【Conclusion】 RARP by extraperitoneal three-hole method is safe and feasible, with exact establishment of extraperitoneal space, few collisions between instruments, low surgical costs, fast postoperative intestinal recovery, aesthetic incision, and satisfactory recovery of urinary control.
ABSTRACT
【Objective】 To explore the safety of transrectal ultrasound-guided transperineal injection of sodium hyaluronate to expand the Dirichlet gap in laparoscopic radical prostatectomy. 【Methods】 A total of 14 healthy male purebred beagle dogs were selected and randomly divided into 2 groups, with 7 in either group.The control group was treated with conventional laparoscopic radical prostatectomy, while the experimental group was treated with laparoscopic radical prostatectomy after 2.5 mL sodium hyaluronate was injected into the Dirichlet gap under the guidance of transrectal ultrasound.The total operation time, prostate separation time, intraoperative blood loss and rectal status of the 2 groups were observed. 【Results】 After the injection of sodium hyaluronate into the Dirichlet gap between the prostate and the rectum, no rectal tissue was found in the prostate, and no obvious damage was found in the posterior rectum in either groups.The postoperative hemoglobin (HGB) was [(118.70±2.56) g/L vs.(122.10±2.19) g/L, P=0.02]; the total operation time was [(141.40±9.80) min vs.(119.10±9.16) min, P<0.05]; the prostate separation time was [(24.99±1.75) min vs.(16.64±2.34) min, P<0.05]; the amount of bleeding was [(47.43±4.32) mL vs.(34.86±5.18) mL, P<0.05] in the control group and experimental group. 【Conclusion】 Laparoscopic radical prostatectomy performed after 2.5 mL of sodium hyaluronate injection into the Dirichlet gap under the guidance of transrectal ultrasound can shorten the total operation time, the separation and resection time of the prostate, and reduce the amount of bleeding, which can improve and reduce the incidence of rectal injury, and prove the feasibility of this approach for prostatic cancer.
ABSTRACT
Objective To investigate the effect of ultrasound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament on postoperative analgesia and inflammation response in elderly patients undergoing robot-assisted laparoscopic radical prostatectomy.Methods A total of 60 elderly patients who had undergone robot-assisted laparoscopic radical prostatectomy from June 2022 to June 2023 were randomly divided into a group of ultra-sound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament combined with general anesthesia(observation group,n = 30)and a general anesthesia group(control group,n = 30).Both groups received patient-controlled intravenous analgesia after surgery.The first compression time of an analgesic pump and the numbers of effective compression and remedial analgesia were recorded.The VAS scores at postsurgical hours 2,12,24,and 48 during rest and coughing were recorded.Interleukin-6(IL-6)and systemic immunoinflammatory index(SII)at one day before surgery and two hours,one day and three days after surgery were recorded.Anal exhaust time,length of postoperative hospital stay and occurrence of adverse reactions were recorded.Results The observation group,as compared with the control group,had significantly longer first compression time of an analgesic pump and had fewer numbers of effective compressions and remedial analgesic administrations(P<0.05).The VAS scores during rest and coughing in the observation group were lower than those in the control group at postsurgical hours 2,12,24,and 48(P<0.05).As compared with one day before surgery,both IL-6 and SII in the two groups increased at 2 hours,1,and 3 days after surgery,but the changes in the observation group were lower than those in the control group(P<0.05).As compared with the control group,the observation group had shorter anal exhaust time and length of postoperative hospital stay,and a lower incidence of adverse reactions(P<0.05).Conclusions Ultrasound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament can provide better postoperative analgesia,reduce inflammatory response and accelerate postoperative recovery in elderly patients undergoing robot-assisted laparoscopic radical prostatectomy.
ABSTRACT
Tumor seeding is rare in prostate cancer. We reported a case of trocar-site metastasis detected at 5 months after robot-assisted laparoscopic radical prostatectomy in a prostate cancer patient with a mixed histology of small cell carcinoma and adenocarcinoma. The patient received 6 cycles of a combination of chemotherapy and immunotherapy and a maintenance regimen of androgen deprivation therapy and immunotherapy at our center. The maintenance of immunotherapy suspended at 10 months after the first dosage due to adverse effect. Three months after the end of chemotherapy, imaging evaluation showed that the tumor had achieved complete remission. Tumor relapse was not detected at 15 months after the suspension of immunotherapy.
ABSTRACT
ABSTRACT Purpose: Salvage robotic-assisted radical prostatectomy (S-RARP) has gained prominence in recent years for treating patients with cancer recurrence following non-surgical treatments of Prostate Cancer. We conducted a systematic literature review to evaluate the role and outcomes of S-RARP over the past decade. Materials and Methods: A systematic review was conducted, encompassing articles published between January 1st, 2013, and June 1st, 2023, on S-RARP outcomes. Articles were screened according to PRISMA guidelines, resulting in 33 selected studies. Data were extracted, including patient demographics, operative times, complications, functional outcomes, and oncological outcomes. Results: Among 1,630 patients from 33 studies, radiotherapy was the most common primary treatment (42%). Operative times ranged from 110 to 303 minutes, with estimated blood loss between 50 to 745 mL. Intraoperative complications occurred in 0 to 9% of cases, while postoperative complications ranged from 0 to 90% (Clavien 1-5). Continence rates varied (from 0 to 100%), and potency rates ranged from 0 to 66.7%. Positive surgical margins were reported up to 65.6%, and biochemical recurrence ranged from 0 to 57%. Conclusion: Salvage robotic-assisted radical prostatectomy in patients with cancer recurrence after previous prostate cancer treatment is safe and feasible. The literature is based on retrospective studies with inherent limitations describing low rates of intraoperative complications and small blood loss. However, potency and continence rates are largely reduced compared to the primary RARP series, despite the type of the primary treatment. Better-designed studies to assess the long-term outcomes and individually specify each primary therapy impact on the salvage treatment are still needed. Future articles should be more specific and provide more details regarding the previous therapies and S-RARP surgical techniques.
ABSTRACT
Introducción El cáncer de próstata es uno de los cánceres más frecuentes en Chile, con 8157 nuevos casos en 2020. A nivel mundial, 5 a 10% de los hombres presentan metástasis al diagnóstico, y la terapia de deprivación androgénica con o sin quimioterapia es el estándar de cuidado para estos pacientes. El uso de tratamiento local en este contexto tiene una recomendación formal debido a la falta de evi-dencia de alta calidad. Algunos estudios retrospectivos han intentado dilucidar el beneficio de la cirugía sobre el tumor primario en el contexto de la enfermedad metastásica, ya que se ha demostrado que es un tratamiento local eficaz para otras neoplasias metastá-sicas. A pesar de estos esfuerzos, el beneficio de la prostatectomía radical citorreductora como tratamiento local en estos pacientes sigue sin estar claro. Métodos Se realizó una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, que se mantiene mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE y Cochrane, entre otras. Se extrajeron los datos de las revisiones sistemáticas, se volvieron a analizar los datos de los estudios primarios, se realizó un metanálisis y se generó una tabla de resumen de resultados utilizando el enfoque GRADE. Resultados y conclusiones Se identificaron 12 revisiones sistemáticas, que incluían siete estudios primarios en total, ninguno de los cuales era un ensayo alea-torizado controlado. Sólo seis de esos siete estudios primarios se utilizaron en el resumen de resultados. A pesar de la falta de evi-dencia de alta calidad, los resultados de este resumen muestran los beneficios de realizar la cirugía en el tumor primario en términos de mortalidad por cualquier causas, mortalidad específica por cáncer y progresión de la enfermedad. También se observó un bene-ficio potencial en las complicaciones locales relacionadas con la progresión del tumor primario, lo que apoya la realización de esta intervención en pacientes con enfermedad metastásica. La ausencia de recomendaciones formales subraya la necesidad de evaluar los beneficios de la cirugía caso por caso, presentando la evidencia disponibles a los pacientes para un proceso de toma de decisiones compartido, teniendo en cuenta las futuras complicaciones locales que podrían ser difíciles de manejar.
Introduction Prostate cancer is one of the most frequent cancers in Chile, with 8157 new cases in 2020. Worldwide, 5 to 10% of men have metastatic disease at diagnosis, and androgen deprivation therapy with or without chemotherapy is the standard of care for these patients. The use of local treatment in this setting has no formal recommendation due to the lack of high- quality evidence. Some retrospective studies have sought to elucidate the benefit of surgery on the primary tumor in the setting of metastatic disease since it has been proven to be an effective local treatment for other metastatic malignant diseases. Despite these efforts, the benefit of cytoreductive radical prostatectomy as local treatment in these patients remains unclear. Methods We searched Epistemonikos, the largest database of systematic reviews in health, which is main-tained by screening multiple information sources, including MEDLINE, EMBASE, and Cochrane, among others. We extracted data from systematic reviews, reanalyzed data from primary studies, conducted a meta- analysis, and generated a summary results table using the GRADE approach. Results and conclusions We identified 12 systematic reviews, including seven studies in total, none of which was a trial. Only six of those seven primary studies were used in the results summary. Despite the lack of high- quality evidence, the results summary shows the benefits of performing surgery on the primary tumor in terms of all- cause mortality, cancer- specific mortality, and disease progression. There was also a potential benefit in local complications related to the progression of the prima-ry tumor, supporting the implementation of this intervention in patients with metastatic disease. The absence of formal recommendations highlights the need to evaluate the benefits of surgery on a case- by- case basis, presenting the available evidence to patients for a shared decision- making process and considering future local complications that could be difficult to manage.
ABSTRACT
Introducción: la dificultad o imposibilidad de lograr una actividad sexual satisfactoria a pesar de estar presentes las condiciones adecuadas para su desarrollo exitoso, se conoce como disfunción sexual. Si la dificultad consiste en alcanzar y mantener la erección necesaria para una penetración se produce una disfunción eréctil. Objetivo: describir la disfunción eréctil en los pacientes con cáncer de próstata sometidos a prostatectomía radical por vía abierta vs. laparoscópica, en el Hospital Universitario Comandante Faustino Pérez Hernández, de Matanzas, entre enero de 2010 y enero de 2020. Materiales y métodos: se realizó un estudio longitudinal retrospectivo en los 40 pacientes que acudieron a la Consulta Provincial de Cáncer de Próstata y les fue realizado cirugía radical, entre enero de 2010 y enero de 2020. Resultados: el 52,5 % de los pacientes tienen un promedio de edad entre 65 y 74 años. Un índice de comorbilidad de Charlson de 3 a 5 puntos predominó en un 75 % de la muestra. En la vía laparoscópica, todos los casos presentaron disfunción eréctil, siendo severa en el 50 % de ellos. El 22,5 % del total no la tuvieron, representando un 30 % de los operados por cirugía abierta. Conclusiones: la prostatectomía radical continúa siendo considerada uno de los tratamientos de elección del cáncer de próstata órgano-confinado. La causa principal de la presencia de disfunción eréctil se atribuye al procedimiento quirúrgico; la edad avanzada puede contribuir a empeorar el pronóstico y las enfermedades coadyuvantes. Son heterogéneos los resultados en la esfera sexual de la prostatectomía radical laparoscópica y la prostatectomía radical abierta, comparados con la bibliografía internacional.
Introduction: the difficulty or impossibility of achieving a successful sexual activity despite being present the adequate conditions for its successful development is known as sexual dysfunction. If the difficulty consists in reaching and maintaining the erection necessary for a penetration, erectile dysfunction occurs. Objective: to describe the erectile dysfunction in patients with prostate cancer undergoing open vs. laparoscopic radical prostatectomy, in the Comandante Faustino Perez Hernandez University Hospital, of Matanzas, between January 2010 and January 2020. Materials and methods: a longitudinal retrospective study was carried out in the 40 patients who attended Prostate Cancer Provincial Consultation and underwent radical surgery between January 2010 and January 2020. Results: 52.5% of the patients were aged between 65 and 74 on average. A Charlson comorbidity index of 3 to 5 points prevailed in 75% of the sample. In the laparoscopic pathway all the cases presented erectile dysfunction, being severe in 50% of them. 22.5% of the total did not have it, representing 30% of those operated by open surgery. Conclusions: radical prostatectomy continues to be considered one of the treatments of choice for organ-confined prostate cancer. The main cause of the presence of erectile dysfunction is attributed to the surgical procedure; advanced age can contribute to a worse prognosis and adjuvant diseases. The results in the sexual sphere of laparoscopic radical prostatectomy and open radical prostatectomy are heterogeneous compared with the international bibliography.
ABSTRACT
ABSTRACT Objectives: Within the tertiary-case database, the authors tested for differences in long-term continence rates (≥ 12 months) between prostate cancer patients with extraprostatic vs. organ-confined disease who underwent Robotic-Assisted Radical Prostatectomy (RARP). Method: In the institutional tertiary-care database the authors identified prostate cancer patients who underwent RARP between 01/2014 and 01/2021. The cohort was divided into two groups based on tumor extension in the final RARP specimen: patients with extraprostatic (pT3/4) vs. organ-confined (pT2) disease. Additionally, the authors conducted subgroup analyses within both the extraprostatic and organ-confined disease groups to compare continence rates before and after the implementation of the new surgical technique, which included Full Functional-Length Urethra preservation (FFLU) and Neurovascular Structure-Adjacent Frozen-Section Examination (NeuroSAFE). Multivariable logistic regression models addressing long-term continence were used. Results: Overall, the authors identified 201 study patients of whom 75 (37 %) exhibited extraprostatic and 126 (63 %) organ-confined disease. There was no significant difference in long-term continence rates between patients with extraprostatic and organ-confined disease (77 vs. 83 %; p = 0.3). Following the implementation of FFLU+ NeuroSAFE, there was an overall improvement in continence from 67 % to 89 % (Δ = 22 %; p < 0.001). No difference in the magnitude of improved continence rates between extraprostatic vs. organ-confined disease was observed (Δ = 22 % vs. Δ = 20 %). In multivariable logistic regression models, no difference between extraprostatic vs. organ-confined disease in long-term continence was observed (Odds Ratio: 0.91; p = 0.85). Conclusion: In this tertiary-based institutional study, patients with extraprostatic and organ-confined prostate cancer exhibited comparable long-term continence rates.
ABSTRACT
Objective:To compare the efficacy and safety of standard treatment with or without adjuvant chemotherapy in patients with highly malignant non-metastatic prostate cancer.Methods:In this prospective non-randomized controlled study, consecutive non-metastatic prostate cancer patients with pathologically proven Gleason score of 9-10 or Gleason score of 5 admitted to Peking University First Hospital were enrolled. Four to six cycles of chemotherapy using docetaxel ± carboplatin regimen were added or not after standard radical therapy. The primary end point was 5-year event-free survival (EFS), and the secondary end points were distant metastasis-free survival (MFS), overall survival (OS), and treatment-related adverse events. The survival curve was drawn by Kaplan-Meier method. The differences between two groups were analyzed by log-rank test.Results:A total of 176 patients were consecutively enrolled from November 2019 to January 2022 of which 138 patients received only standard radical therapy (control group), and 38 patients received adjuvant chemotherapy after standard radical therapy (chemotherapy group). The median follow-up time was 13.4 (2.0-34.0) months. All patients survived. The 30-month EFS rates in the chemotherapy and control groups were 100% and 85.6%, respectively ( P=0.064). There were no events in the chemotherapy group, while there were 12 cases of events in the control group, including 6 cases of biochemical recurrence and 6 cases of imaging progression. The 30-month MFS rates in two groups were 100% and 91.9%, respectively ( P=0.205). After the 1 vs. 2 propensity score matching, the EFS and MFS rates in two groups were 100% vs. 85.7% ( P=0.056), and 100% vs. 92.2% ( P=0.209), respectively. The incidence rates of grade 2 and above urinary toxicity in the chemotherapy and control groups were 2.6% and 7.2% ( P=0.354), respectively. The incidence rates of grade 2 and above rectal toxicity were 5.3% and 5.1% ( P=0.711), respectively. Grade 3 and above chemotherapy-related toxicity in the chemotherapy group were leukopenia (31.6%), thrombocytopenia (2.6%) and alopecia (13.2%). Conclusion:The addition of adjuvant chemotherapy after standard radical therapy tends to improve the overall EFS of patients with highly malignant prostate cancer, and the adverse effects are tolerable, which should be confirmed by long-term follow-up results.
ABSTRACT
Objective:To analyze the biochemical failure rate and its predictive factors after radical prostatectomy (RP) in patients with high-risk localized prostate cancer.Methods:The data of 166 patients with high-risk localized prostate cancer who underwent RP surgery in Peking university cancer hospital from January 2015 to November 2021 were retrospectively reviewed. The average age was 65.4±6.2 years old, and the average body mass index (BMI) was 24.86±3.23 kg/m 2. The median prostate-specific antigen (PSA) was 19.84 (10.98, 44.47) ng/ml, PSA density was 0.68 (0.34, 1.32)ng/ml 2, and prostate volume was 31.20 (25.58, 40.23) ml. Biopsy pathology Gleason score according to the International society of Urological Pathology(ISUP) grade group: 18 cases of group 1, 33 cases of group 2, 30 cases of group 3, 51 cases of group 4, and 33 cases of group 5, 1 case was unknown. The percentage of puncture positive needles was (55.4±25.7)%, and the largest linear length of positive lesions was 80.0% (60.0%, 90.0%). Preoperative clinical stage : 14 cases in ≤T 2b stage, 117 cases in T 2c stage, 13 cases in T 3a stage and 22 cases in ≥T 3b stage; 157 cases in N 0 stage, 9 cases in N 1 stage. One hundred and three patients (62.0%) were assessed by traditional imaging and 63(38.0%) were assessed by PSMA PET-CT. The patients underwent laparoscopic radical prostatectomy. 64 patients (38.6%) received neoadjuvant therapy, including 37 received neoadjuvant therapy for 1-3 months, 23 for 4-6 months and 4 for over 6 months. The postoperative pathological characteristics, treatment and prognosis of the patients were analyzed. The primary endpoint was biochemical failure, including biochemical persistence(BCP, defined as PSA≥0.1ng/ml at 4-6 weeks after operation, and confirmed by re-examination at least 1 week interval) and biochemical recurrence(BCR, PSA falling below 0.1ng/ml after operation and then rising ≥0.2 ng/ml without adjuvant therapy or after the end of adjuvant treatment). Results:Compared with preoperative clinicopathological characteristics, 48(28.9%) cases had postoperative pathological ISUP upgrade, 98 (59.0%)cases had T stage upgrade, and 13 (7.8%) cases had N stage upgrade. The rate of positive margins was 53%, and apex margin was the most common positive site (65.9%). The postoperative PSA in 114 patients (68.7%) decreased to less than 0.1ng/ml, of which 74 patients didn't receive the therapy and 40 patients received adjuvant therapy. 52 patients (31.3%) had postoperative PSA more than 0.1ng/ml and among them, 51 cases received salvage treatment. 5 patients (3.0%) underwent PSA progression during adjuvant or salvage endocrine therapy and were considered to have castration resistance. After a median follow-up time of 25.5 (12.0, 40.0) months, 78 patients (48.4%, 78/161) experienced biochemical failure, including 49 BCP and 29 BCR, the median time of biochemical failure was 30.0 (95% CI 14.5-45.5) months. Adjuvant therapy could reduce the rate of BCR (31.1% and 15.8%, P=0.08). Baseline PSA, PSA density, proportion of pathological ISUP ≥4, proportion of pathological T stage ≥T 3a, adjuvant therapy, and positive surgical margins were significantly associated with biochemical failure ( P=0.034, 0.002, 0.004, 0.025, <0.001and 0.047). Multivariate Cox regression analysis showed that adjuvant therapy ( P<0.001, OR=0.12), PSA density ( P=0.03, OR=1.19) and positive surgical margins ( P=0.034, OR=1.80) were independent factors for biochemical failure. Conclusions:Patients with high-risk localized prostate cancer have a high rate of biochemical failure after RP and need to receive RP-based multimodal therapy. Adjuvant therapy, PSA density and positive surgical margins are independent factors associated with postoperative biochemical failure.
ABSTRACT
Objective:To evaluate the clinical value of the frozen section assessment of surgical margin in preserving urinary continence and erectile function during robotic radical prostatectomy (RARP).Methods:From Feb. 2022 to Jul 2023, 11 patients underwent RARP using intrafascial dissection technique and frozen section assessment in Beijing United Family Hospital. The median age was 64(61, 69)years, the median PSA was 8.0(6.0, 11.2)ng/ml, and the median IIEF-5 was 17.5(10.3, 22.0). All the patients were diagnosed with prostate cancer and PSMA-PET/CT showed negative for metastasis. The da Vinci Si platform, 4-arm, transabdominal anterior approach was applied in all cases. The prostate specimen was removed from the umbilical incision and submitted to the pathology department for frozen section assessment. If the frozen section assessment showed cancer in the surgical margin, a secondary resection of the ipsilateral periprostatic fascia and neurovascular bundle (NVB) was performed. Totally, 3 cases underwent secondary resection, who underwent unilateral NVB-sparing, and the other 8 cases underwent bilateral NVB-sparing surgery. In follow-up, the PSA, urinary continence and erectile function was assessed and recorded.Results:All the surgeries of 11 cases were successful, without convertion to open surgery. The median operation time was 260(225, 285)minutes, the median blood loss was 200(100, 300)ml, the median hospital stay was 4(3, 5)days. There was no over Clavien Dindo Ⅱ perioperative complications.The median catheter indwelling time was 12(10, 14) days, with 10 cases achieving full continence upon catheter removal. The median follow-up time was 10 months. The median PSA level at 3 months, 6 months and 9 months postoperatively was 0.017(0.006, 0.170)ng/ml, 0.015(0.006, 0.390)ng/ml, and 0.007(0.006, 0.650)ng/ml respectively. The median IIEF-5 at 3 months, 6 months and 9 months postoperatively was 0.017(0.006, 0.170)ng/ml, 0.015(0.006, 0.390)ng/ml, 0.007(0.006, 0.650)ng/ml respectively.The median IIEF-5 at 3 months, 6 months and 9 months post-operation was 5.0(4.5, 11.0), 7.5(4.3, 17.5), and 9.5(6.0, 17.5)respectively.Conclusions:The RARP combined with frozen section assessment of surgical margin has excellent safety profile and can achieve favorable clinical value in tumor control, NVB preserving, urinary continence and erectile function.
ABSTRACT
Introduction@#Limited access to the perineum and limited operating room space are just some of the limitations of the standard lithotomy docking for robot-assisted radical prostatectomy (RARP-LD). The side-docking technique (RARP-SD) may address these problems.@*Methods@#Thirty cases of robot-assisted radical prostatectomy were matched to 120 cases of RARP-LD cases by propensity scoring using age, body mass index (BMI), clinical T stage, biopsy Gleason score, and ultrasound prostate volume. Operative and docking time, complications were used to compare peri-operative and safety outcomes.@*Results@#Evaluation of 30 RARP-LD and 30 RARP-SD cases was done after propensity matching. Patient age, BMI, clinical T stage, biopsy Gleason score, and prostate volume were similar between the two groups (p>0.050). The mean docking time of RARP-SD is shorter than that of RARP-LD cases (7.56 vs. 4.12, p <0.001), but this did not translate to a shorter operative time. There were less peri-operative complications in the RARP-SD cases.@*Conclusions@#RARP-SD has a docking time and produces less complication than RARP-LD.

Radical prostatectomy (RP) is the standard treatment for patients with early-stage of prostate cancer,but often causes urinary incontinence and other complications, which harm patients’ quality of life. The protection and reconstruction of urinary continence-related structures during the operation are significant approaches to reduce the incidence of urinary incontinence and restore urinary continence. This article reviewed the surgical approaches of radical prostatectomy, anatomy of urinary continence-related structures (bladder neck, functional urethra, supporting structures, nerves and vessels) and the protective skills,hoping to provide reference for the treatment of early-stage prostate cancer.
ABSTRACT
【Objective】 To explore the efficacy of modified prostate tip separation technique combined with laparoscopic radical prostatectomy based on propensity score matching (PSM) in the treatment of prostate cancer. 【Methods】 A total of 74 prostate cancer patients treated during Jan.2019 and Dec.2022 with modified prostate tip separation technique combined with laparoscopic radical prostatectomy were included in the combined group, and another 63 prostate cancer patients treated during the same period with laparoscopic radical prostatectomy were selected as the control group. Altogether 58 pairs of patients were matched with PSM. The perioperative indicators, incidence of complications, urinary control function and sexual function before and one month after surgery between the two groups after matching were compared. 【Results】 There were no statistically significant differences in general data between the two groups (P>0.05). One month after operation, the scores of the International Urinary Incontinence Questionnaire (ICIQ-SF) and International Erectile Function Questionnaire (IIEF-5) in both groups decreased, while the Expanded Prostate Cancer Index Composite (EPIC-UIN) and International Prostate Symptom Score (IPSS) in both groups increased (P<0.05). The scores of ICIQ-SF [(9.02±1.98) vs. (11.38±2.04)] and IPSS [(19.67±4.19) vs. (21.68±4.23)] were lower in the combined group than in the control group (P<0.05), while the scores of EPIC-UIN [(70.49±6.82) vs. (63.34±6.48)] and IIEF-5 [(18.17±1.73) vs. (16.72±1.58)] were higher in the combined group than in the control group (P<0.05). Compared with the control group, the combined group had shorter catheter retention time [(7.38±1.97) d vs. (5.11±1.82) d] and hospital stay [(13.18±2.23) d vs. (11.74±2.09) d], lower incidence of complications (22.41% vs. 6.90%), and higher positive rate of incision margin (8.62% vs. 20.69%) (P<0.05). 【Conclusion】 PSM can balance the differences between groups. The modified prostate tip separation technique combined with laparoscopic radical prostatectomy can improve the urinary control function, have little impact on sexual function, and cause fewer postoperative complications. However, the risk of positive incision margin is high, and further modification is needed to achieve the best therapeutic effects.
