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.

After receiving local treatment, many patients will develop a biochemical recurrence (BCR) in the absence of detectable distant disease (cM0) and comprise a significant proportion (20.1%) of prostate cancer disease states. The natural history of patients with BCR ranges from those with indolent, nonprogressive, slow prostate-specific antigen (PSA)-only progression to those ultimately destined to develop metastases and progress to a cancer-specific death. Pathologic predictors of BCR, clinical progression, and cancer-specific mortality are well established in the literature, although multiple novel predictors are emerging, which are highlighted. Traditional imaging cannot reliably distinguish local versus distant microscopic metastasis at the PSA levels that have been shown to confer survival advantage for salvage radiation therapy. We review past and present imaging standards and discuss novel imaging modalities, which may improve staging and offer opportunity for novel salvage therapies, including salvage lymph node dissection and stereotactic beam radiation therapy. With an emphasis on BCR after radical prostatectomy, both curative and palliative treatments are reviewed.

Abstract Objective 18F-labeled prostate-specific membrane antigen (PSMA) ligand, [18F]PSMA-1007, has the benefit of a higher synthetic yield and minimal excretion in the urine. High detection efficacy was reported in biochemical recurrence (BCR) of prostate cancer after radical prostatectomy. Thus, we evaluated the preliminary diagnostic utility of [18F]PSMA-1007 PET in patients with prostate cancer, focusing on the BCR which is not detected on conventional imaging. Methods We enrolled a total of 28 patients (age 51–79 years) with BCR of prostate cancer. BCR was defined as a continuous increase in PSA after radical prostatectomy or radiation therapy without any apparent recurrent lesions on conventional diagnostic imaging (CT and bone scintigraphy). PSMA-PET scanning was performed approximately 60 min after intravenous injection of [18F]PSMA-1007 (259 ± 37 MBq). PSMA-PET images were evaluated for lesion detection as well as its relation to PSA values and location. Results Abnormal uptake, which was suspected to be recurrence or metastasis, was detected in 92.9% (26/28) of patients with BCR. The SUVmax was 8.4 ± 6.4 in local recurrence, 11.5 ± 11.8 in pelvic lymph nodes (LN), and 4.1 ± 1.6 in bone metastasis. The detection rates were 66.7% in the PSA group-1 (0.1–0.5 ng/mL), 85.7% in the PSA group-2 (0.5–1.0 ng/mL), and 100% in the PSA group-3 (above 1.0 ng/mL). Among the PET-positive BCR patients (n = 26), local recurrence was detected in 57.7% (15/26), pelvic LN in 42.3% (11/26), and bone metastasis in 15.4% (4/26). In 53% (8/15) of BCR patients who were suspected of local recurrence, focal uptake was detected adjacent to the bladder on [18F]PSMA-1007 PET. This suggested the significant advantage of having minimal physiological urine excretion. Conclusions [18F]PSMA-1007 PET showed a high detection rate in recurrent and metastatic lesions. In patients with BCR, its high detection led to suitable treatment strategies, such as salvage radiation therapy or surgical removal of recurrent lymph nodes.

Biochemical recurrence after treatment of prostate cancer occurs in 30–50 % of patients. Confirming that recurrence is localized to the pelvis is challenging as PSA is nonspecific and imaging modalities are imperfect in identifying location of recurrent disease. Salvage therapy after radical prostatectomy is limited to external beam radiotherapy and androgen-deprivation therapy. After radiotherapy, local salvage therapy consists of salvage radical prostatectomy, salvage brachytherapy, and salvage high-intensity ultrasound. Each treatment modality provides various rates of cure but with its own side-effect profile, prompting discussion between patient and clinician to determine appropriate treatment course. Local salvage therapy has the potential to be curative and disease control has been reported in a substantial number of select patients. However, the survival benefit of these therapies has yet to be definitively proved.

The limitations of the biomarker prostate-specific antigen (PSA) necessitate the pursuit of biomarkers capable of better identifying high-risk prostate cancer (PC) patients in order to improve their therapeutic management and outcomes. Aggressive prostate tumors characteristically exhibit high rates of glycolysis and lipogenesis. Glycerol 3-phosphate phosphatase (G3PP), also known as phosphoglycolate phosphatase (PGP), is a recently identified mammalian enzyme, shown to play a role in the regulation of glucose metabolism, lipogenesis, lipolysis, and cellular nutrient-excess detoxification. We hypothesized that G3PP may relieve metabolic stress in cancer cells and assessed the association of its expression with PC patient prognosis. Using immunohistochemical staining, we assessed the epithelial expression of G3PP in two different radical prostatectomy (RP) cohorts with a total of 1797 patients, for whom information on biochemical recurrence (BCR), metastasis, and mortality was available. The association between biomarker expression, biochemical recurrence (BCR), bone metastasis, and prostate cancer-specific survival was established using log-rank and multivariable Cox regression analyses. High expression of G3PP in PC epithelial cells is associated with an increased risk of BCR, bone metastasis, and PC-specific mortality. Multivariate analysis revealed high G3PP expression in tumors as an independent predictor of BCR and bone metastasis development. High G3PP expression in tumors from patients eligible for prostatectomies is a new and independent prognostic biomarker of poor prognosis and aggressive PC for recurrence, bone metastasis, and mortality.

Abstract Background Prostate Membrane Specific Antigen (PSMA) positron emission tomography (PET) and multiparametric MRI (mpMRI) have shown high accuracy in identifying recurrent lesions after definitive treatment in prostate cancer (PCa). In this study, we aimed to outline patterns of failure in a group of post-prostatectomy patients who received adjuvant or salvage radiation therapy (PORT) and subsequently experienced biochemical recurrence, using 18F-PSMA PET/CT and mpMRI. Methods PCa patients with biochemical failure post-prostatectomy, and no evident site of recurrence on conventional imaging, were enrolled on two prospective trials of first and second generation 18F-PSMA PET agents (18F-DCFBC and 18F-DCFPyL) in combination with MRI between October 2014 and December 2018. The primary aim of our study is to characterize these lesions with respect to their location relative to previous PORT field and received dose. Results A total of 34 participants underwent 18F-PSMA PET imaging for biochemical recurrence after radical prostatectomy and PORT, with 32/34 found to have 18F-PSMA avid lesions. On 18F-PSMA, 17/32 patients (53.1%) had metastatic disease, 8/32 (25.0%) patients had locoregional recurrences, and 7/32 (21.9%) had local failure in the prostate fossa. On further exploration, we noted 6/7 (86%) of prostate fossa recurrences were in-field and were encompassed by 100% isodose lines, receiving 64.8–72 Gy. One patient had marginal failure encompassed by the 49 Gy isodose. Conclusions 18F-PSMA PET imaging demonstrates promise in identifying occult PCa recurrence after PORT. Although distant recurrence was the predominant pattern of failure, in-field recurrence was noted in approximately 1/5th of patients. This should be considered in tailoring radiotherapy practice after prostatectomy. Trial registrationwww.clinicaltrials.gov, NCT02190279 and NCT03181867.
