Salvage radical prostatectomy (sRP) has evolved from open to minimally invasive approaches. sRP can be offered to patients with local recurrence to improve biochemical recurrence (BCR)-free and overall survival. We evaluate oncological outcome and continence after retropubic (RRP), conventional (cRARP), and Retzius-sparing robotic (rsRARP) surgery. Materials/methods: A total of 53 patients undergoing sRP between 2010 and 2020 were included. Follow-up included oncological outcome and continence. Results: sRP was done as RRP (n = 25), cRARP (n = 7), or rsRARP (n = 21). Median blood loss was 900 mL, 500 mL, and 300 mL for RRP, cRARP, and rsRARP, respectively. At 12 months, 5 (20%), 0, and 4 (19%) patients were continent, 9 (36%), 3 (43%), and 7 (33%) had grade 1 incontinence, 5 (20%), 2 (29%), and 3 (14%) had grade 2 incontinence, and 3 (12%), 2 (29%), and 4 (19%) had grade 3 incontinence for RRP, cRARP, or rsRARP, respectively. During a mean follow-up of 52.6 months, 16 (64%), 4 (57%), and 3 (14%) developed BCR in the RRP-, cRARP-, and rsRARP-group, respectively. Conclusions: Over the years, sRP has shifted from open to laparoscopic/robotic surgery. RARP shows good oncological and functional outcome. rsRARP ensures direct vision on the rectum during preparation and can therefore increase safety and surgeon’s confidence, especially in the salvage setting.

Salvage Radical Prostatectomy

Patients with isolated local recurrence of prostate cancer after radiation therapy may potentially be cured of their disease by salvage radical prostatectomy (RP). The stage-specific 5-year cancer-control rates of salvage RP resemble those of standard RP. However, the ability to effectively administer salvage treatment to patients with radiorecurrent disease is compromised by the lack of diagnostic tests with sufficient sensitivity and specificity to detect local recurrence at an early stage while it is amenable to local salvage therapy. By the time biochemical recurrence is declared using the current American Society for Therapeutic Radiology and Oncology definition, the majority of patients have advanced local disease, precluding successful local salvage therapy. When salvage RP is performed at prostate-specific antigen levels of 10 ng/mL or less, an estimated 70% of patients are free of disease at 5 years. With better patient selection and technical modifications, the morbidity associated with salvage RP has improved substantially. Rates of urinary incontinence and anastomotic stricture are acceptable, although one third of patients will experience these complications. Salvage cryotherapy is a minimally invasive alternative to salvage RP, but cancer-control rates appear to be inferior and it does not provide a clear advantage over salvage RP in terms of reduced morbidity. Patients with local recurrence after radiation therapy are at increased risk of metastatic progression and cancer-specific mortality. Currently, salvage RP represents the only curative treatment option for these patients. Salvage RP may favorably alter the natural history of biochemical recurrence after radiation therapy, but it must be instituted early in the course of recurrent disease to be effective.

The Impact

5065 Background: Early hormonal therapy has been used in the salvage setting for men with biochemical recurrence following radical prostatectomy (RP), but no studies to date have been able to evaluate whether such treatment prolongs survival. We examined the impact of salvage hormonal therapy on overall survival (OS) in a cohort with long-term follow-up, and attempted to identify the subgroup most likely to benefit. Methods: Retrospective analysis of a cohort of 488 men undergoing RP at Johns Hopkins Hospital from 1982–2004, who experienced biochemical recurrence and received no salvage therapy (n = 386) or salvage hormonal therapy (n = 102); no one received adjuvant therapy. Survival was defined from biochemical recurrence to death from all causes, and analyzed with proportional hazards models with time-dependent covariates. Results: With median follow-up of 6 years after recurrence and 9 years after RP, there were 143 deaths (29%), including 105 from prostate cancer. After adjusting for PSA doubling time (PSADT), RP Gleason score, and year of surgery, hormonal therapy did not significantly improve OS for all men, compared to no salvage therapy: hazard ratio (HR) = 0.72 (95% confidence interval (CI): 0.45–1.17), p = 0.187. However, when restricted to men with early recurrence, i.e. within 2 years of RP, and with a rapid PSADT<6 months, hormonal therapy was associated with a large, significant improvement in OS: HR = 0.25 (95% CI: 0.08–0.71), p = 0.0095. This subgroup comprised 22% of the cohort. In contrast, there was no benefit of salvage hormonal therapy in men with early recurrence and PSADT>6 months: HR = 1.96 (95% CI: 0.89–4.31), p = 0.093, nor those who recurred more than 2 years after RP, regardless of PSADT. Conclusions: This study suggests that early salvage hormonal therapy may significantly and substantially prolong overall survival in the subgroup of men who experience an early biochemical recurrence with a rapid PSADT. These results are consistent with early recurrences being indicative of metastatic disease, while later recurrences are more likely to represent local recurrence. If validated, these results may provide useful stratification criteria for clinical trials. No significant financial relationships to disclose.

100 Background: Currently there is little data to guide the use of post-radical prostatectomy (RP) testosterone replacement therapy in prostate cancer. We sought to evaluate the impact of post-RP testosterone replacement on prostate cancer outcomes in a large national cohort. Methods: We conducted a population-based cohort study using the Veterans Affairs Informatics and Computing Infrastructure. We identified node-negative and non-metastatic prostate cancer patients diagnosed between 2001-2015 treated with RP. We excluded patients for missing covariate and follow-up data. We then coded receipt of testosterone replacement after RP as a time-dependent covariate. Other covariates included: age, Charlson Comorbidity index, diagnosis year, body mass index, race, PSA, clinical T/N/M stage, Gleason score, and receipt of hormone therapy. Biochemical recurrence was defined as a post-RP PSA≥0.2. We evaluated prostate cancer-specific survival, overall survival, and biochemical recurrence free survival using multivariable Cox regression. Results: Our cohort included 28,651 patients, of whom 469 (1.6%) received testosterone replacement after RP. Median follow up was 7.4 years. There were no differences in clinical T stage, median post-RP PSA (testosterone: 0 non-testosterone: 0; p = 0.18), or hormone therapy use between treatment groups. Testosterone patients were more likely to be of younger age, have higher comorbidity, non-black, have a lower median pre-treatment PSA (5.0 vs 5.8; p < 0.001), and have higher BMI. The median time from RP to TRT was 3.0 years. After controlling for potential confounders, we found no difference in prostate cancer specific mortality (HR 0.73; 95% CI 0.32-1.62; p = 0.43), overall survival (HR 1.11; 95% CI 0.86-1.44; p = 0.43), non-cancer mortality (HR 1.17; 95% CI 0.89-1.55; p = 0.26) biochemical recurrence free survival (HR 1.07; 95% CI 0.84-1.36; p = 0.59) between testosterone users and non-users. Conclusions: Our results suggest that testosterone replacement is safe in prostate cancer patients who have undergone RP, though prospective data is necessary to confirm this finding.

Prostate cancer recurrence in patients previously treated with radical prostatectomy and radiation therapy is challenging. Re-irradiation could be an option, but data regarding efficacy and safety are lacking. We retrospectively evaluated salvage re-irradiation for local recurrence after prostatectomy and external beam radiation therapy. We collected data from 48 patients who underwent salvage reirradiation with stereotactic radiation therapy for local prostate cancer recurrence in the prostatic bed at four French centers. Fifteen patients (31%) were on androgen deprivation therapy during stereotactic radiotherapy. Biochemical response and relapse-free survival were analyzed, and post-treatment toxicities were assessed according to the Common Terminology of Adverse Events criteria. Five patients had grade 3 late bladder toxicity (cystitis), three had grade 3 late incontinence, and one had grade 3 late chronic pain. At three months, 83% of patients had a positive biochemical response. The median follow-up was 22 months. At the end of the follow-up, 21 patients (43%) had a biochemical relapse. The median time to biologic relapse was 27 months. The biochemical relapse rates at 1 and 2 years were 80% and 52%, respectively. In conclusion, salvage re-irradiation for recurrent prostate cancer in the prostate bed may generate significant toxicity rates, and a prospective study with appropriate patient selection is needed to evaluate its effectiveness.

Objectives: To develop a model to predict biochemical recurrence (BCR) after radical prostatectomy (RP), using artificial intelligence (AI) techniques. Patients and Methods: This study collected data from 7,128 patients with prostate cancer (PCa) who received RP at 3 tertiary hospitals. After preprocessing, we used the data of 6,755 cases to generate the BCR prediction model. There were 16 input variables with BCR as the outcome variable. We used a random forest to develop the model. Several sampling techniques were used to address class imbalances. Results: We achieved good performance using a random forest with synthetic minority oversampling technique (SMOTE) using Tomek links, edited nearest neighbors (ENN), and random oversampling: accuracy = 96.59%, recall = 95.49%, precision = 97.66%, F1 score = 96.59%, and ROC AUC = 98.83%. Conclusion: We developed a BCR prediction model for RP. The Dr. Answer AI project, which was developed based on our BCR prediction model, helps physicians and patients to make treatment decisions in the clinical follow-up process as a clinical decision support system.

Long Term Follow Up

A total of 342 previously untreated eligible children were entered into the first Intergroup Ewing's Sarcoma Study (IESS) between May 1973 and November 1978. In group I institutions, patients were randomized between treatment 1 (radiotherapy to primary lesion plus cyclophosphamide, vincristine, dactinomycin, and Adriamycin [doxorubicin; Adria Laboratories, Columbus, OH] [VAC plus ADR]) or treatment 2 (same as treatment 1 without ADR), and group II institutions randomized patients between treatment 2 or treatment 3 (same as treatment 2 plus bilateral pulmonary radiotherapy [VAC plus BPR]). The percentages of patients relapse-free and surviving (RFS) at 5 years for treatments 1, 2, and 3 were 60%, 24%, and 44%, respectively. There was strong statistical evidence of a significant advantage in RFS for treatment 1 (VAC plus ADR) versus 2 (VAC alone) (P less than .001) and 3 (P less than .05) and also of treatment 3 versus 2 (P less than .001). Similar significant results were observed with respect to overall survival. Patients with disease at pelvic sites have significantly poorer survival at 5 years than those with disease at nonpelvic sites (34% v 57%; P less than .001). Among pelvic cases, there was no evidence of differing survival by treatment (P = .81), but among nonpelvic cases, there was strong evidence of differing survival by treatment (P less than .001). The overall percentage of patients developing metastatic disease was 44%; the percentages by treatments 1, 2, and 3 were 30%, 72%, and 42%, respectively. The overall incidence of local recurrence was 15%, and there was no evidence that local recurrence rate differed by treatment. Patient characteristics related to prognosis, both with respect to RFS and overall survival experience, were primary site (nonpelvic patients were most favorable) and patient age (younger patients were more favorable).

PURPOSE Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly and selectively releases alkylating agents into tumor cells. The phase II HORIZON trial evaluated the efficacy of melflufen plus dexamethasone in relapsed and refractory multiple myeloma (RRMM), a population with an important unmet medical need. PATIENTS AND METHODS Patients with RRMM refractory to pomalidomide and/or an anti-CD38 monoclonal antibody received melflufen 40 mg intravenously on day 1 of each 28-day cycle plus once weekly oral dexamethasone at a dose of 40 mg (20 mg in patients older than 75 years). The primary end point was overall response rate (partial response or better) assessed by the investigator and confirmed by independent review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. The primary analysis is complete with long-term follow-up ongoing. RESULTS Of 157 patients (median age 65 years; median five prior lines of therapy) enrolled and treated, 119 patients (76%) had triple-class–refractory disease, 55 (35%) had extramedullary disease, and 92 (59%) were refractory to previous alkylator therapy. The overall response rate was 29% in the all-treated population, with 26% in the triple-class–refractory population. In the all-treated population, median duration of response was 5.5 months, median progression-free survival was 4.2 months, and median overall survival was 11.6 months at a median follow-up of 14 months. Grade ≥ 3 treatment-emergent adverse events occurred in 96% of patients, most commonly neutropenia (79%), thrombocytopenia (76%), and anemia (43%). Pneumonia (10%) was the most common grade 3/4 nonhematologic event. Thrombocytopenia and bleeding (both grade 3/4 but fully reversible) occurred concomitantly in four patients. GI events, reported in 97 patients (62%), were predominantly grade 1/2 (93%); none were grade 4. CONCLUSION Melflufen plus dexamethasone showed clinically meaningful efficacy and a manageable safety profile in patients with heavily pretreated RRMM, including those with triple-class–refractory and extramedullary disease.

Purpose Until recently, melphalan and prednisone were the standards of care in elderly patients with multiple myeloma. The addition of thalidomide to this combination demonstrated a survival benefit for patients age 65 to 75 years. This randomized, placebo-controlled, phase III trial investigated the efficacy of melphalan and prednisone plus thalidomide in patients older than 75 years with newly diagnosed myeloma. Patients and Methods Between April 2002 and December 2006, 232 previously untreated patients with myeloma, age 75 years or older, were enrolled and 229 were randomly assigned to treatment. All patients received melphalan (0.2 mg/kg/d) plus prednisone (2 mg/kg/d) for 12 courses (day 1 to 4) every 6 weeks. Patients were randomly assigned to receive 100 mg/d of oral thalidomide (n = 113) or placebo (n = 116), continuously for 72 weeks. The primary end point was overall survival. Results After a median follow-up of 47.5 months, overall survival was significantly longer in patients who received melphalan and prednisone plus thalidomide compared with those who received melphalan and prednisone plus placebo (median, 44.0 v 29.1 months; P = .028). Progression-free survival was significantly prolonged in the melphalan and prednisone plus thalidomide group (median, 24.1 v 18.5 months; P = .001). Two adverse events were significantly increased in the melphalan and prednisone plus thalidomide group: grade 2 to 4 peripheral neuropathy (20% v 5% in the melphalan and prednisone plus placebo group; P < .001) and grade 3 to 4 neutropenia (23% v 9%; P = .003). Conclusion This trial confirms the superiority of the combination melphalan and prednisone plus thalidomide over melphalan and prednisone alone for prolonging survival in very elderly patients with newly diagnosed myeloma. Toxicity was acceptable.
