Q

<p>ProtecT trial</p>

A

<p>Randomized 1,643 men with screen-detected PCa to active monitoring, radical prostatectomy, or radiation therapy with curative intent. At a median of 10 years, no differences in PCa mortality were observed across groups (PCa deaths per 1,000 person years: active monitoring 1.5, surgery 0.9, radiation 0.7, p = 0.48).</p>

Q

<p>PIVOT trial</p>

A

<p>The Prostate Cancer Intervention Versus Observation Trial (PIVOT) found that radical prostatectomy did not improve overall or disease-specific mortality at a median follow-up of 12.7 years.1,3 However, surgery reduced the risk of progression (40.9% vs 68.4%; HR 0.39, 95% CI 0.32-0.48) and treatment for progression (33.5% vs 59.7%; HR 0.45, 95% CI 0.36-0.56) compared to watchful waiting.</p>

<p>SPCG 4</p>

A

<p>The Scandinavian Prostate Cancer Group Study No. 4 (SPCG 4) reported an improvement in overall and disease-specific mortality for men undergoing radical prostatectomy compared to watchful waiting. The absolute OS benefit favoring prostatectomy was 12%, which translated to a median 2.9 years of life gained at median 23 years of follow-up</p>

Q

<p>Prostate cancer Active surveillance inclusion criteria</p>

A

<p>Men with very low risk and low risk PCa per AUA and NCCN guidelines (or clinically insignificant disease per Epstein criteria) are typically candidates for AS.
<br></br>
<br></br>These criteria include:
<br></br>1. Grade Group 1 (Gleason score ≤ 6)
<br></br>2. Clinical stage ≤ T2a
<br></br>3. PSA density < 0.15ng/mL/g
<br></br>4. < or ≤ 3 positive biopsy cores
<br></br>5. ≤ 50% cancer in each core</p>

Q

<p>PUNCH trial</p>

A

<p>randomized patients with high-risk, clinically localized prostate cancer to neoadjuvant chemohormonal therapy with docetaxel and ADT plus radical prostatectomy or radical prostatectomy alone. Results indicated no difference in 3-year biochemical progression free rates, the primary endpoint. However, neoadjuvant chemohormonal therapy was associated with improved MFS and OS compared to surgery alone</p>

<p>RADICALS-RT trial</p>

A

<p>enrolled 1396 men with intermediate-to-high risk prostate cancer after radical prostatectomy, and randomized them to adjuvant vs. early salvage RT demonstrated no statistically significant difference with regards to biochemical progression-free survival and freedom from subsequent hormonal therapy between the treatment arms. Adjuvant radiotherapy was associated with an increased number of urinary and bowel adverse effects.</p>

Q

<p>What is EBRT</p>

A

<p>External Beam Radiation Therapy
<br></br>
<br></br>delivered using a linear accelerator (LINAC.) The LINAC generates a high energy electron beam that is passed through a tungsten target to generate a photon beam. These beams reach megavoltage energies (commonly 6-15 MV) capable of delivering ionizing radiation energies to targets deep in the body.</p>

<p>Dimensional Conformal Radiation Therapy.
<br></br>
<br></br>The process of using CT images to generate a 3-dimensional radiation plan to maximize radiation dose to the target volume while minimizing dose to neighboring organs at risk (OAR’s)</p>

Q

<p>What is IMRT</p>

A

<p>Intensity Modulated Radiation Therapy (IMRT) is a specialized form of EBRT. The process of generating an IMRT plan is similar to the generation of a 3DCRT plan. However, IMRT utilizes a process called inverse planning.</p>

A

<p>compared 46 Gy of pelvic EBRT with dose-escalation by 3DCRT (DE-EBRT) boost to 78 Gy or with an LDR boost.
<br></br>
<br></br>Men with both NCCN intermediate- (N==122, 30.7%) and high-risk disease (N=276, 69.3%) were eligible and received 1 year of ADT with 8 months delivered neoadjuvantly. With a median follow-up of 6.5 years there was a significantly greater risk of bPFS in men treated with DE-EBRT vs brachytherapy boost among the total population (HR=2.04, p=0.004) and among men with NCCN intermediate-risk disease (p=0.003). No benefit in prostate cancer specific or all-cause mortality could be observed.</p>

Q

<p>PROMIS trial</p>

A

<p>576 men underwent a 1.5 Tesla mpMRI followed by both TRUS biopsy and a template mapping prostate biopsy. For clinically significant cancer, mpMRI was more sensitive (93%; 95% CI 88-96%) and less specific (41%; 95% CI 36-46%). The authors concluded that using mpMRI to triage men might allow 27% of patients to avoid a primary biopsy and 5% fewer clinically insignificant cancers would be detected</p>

<br></br>ADT + Abiraterone: demonstrated that at a median follow-up of 40 months, abiraterone in addition to ADT led to an OS benefit in a group of 1,917 men. A 37% relative improvement in survival was noted with a HR of 0.63 (95% CI, 0.52-0.76, P < 0.0001).

<p>1509 patients w/ nmCRPC, PSA DT of 10 mos or less, baseline PSA level of 2 ng/mL and an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 were randomized 2:1 to receive darolutamide 600 mg BID vs. placebo while continuing ADT. Median f/u was 17.9 mos. The median MFS was 40.4 mos with darolutamide compared to 18.4 mos w/ placebo (HR 0.41, 95% CI 0.34 to 0.50; p<0.001)
<br></br>
<br></br>Risk of death was lower and time to pain progression was longer.</p>

<br></br>
<br></br>Caveat: Metanephrines are more sensitive than catecholamines since metabolism is continuous, unlike catecholamine release which occurs episodically.2 The higher sensitivity of metanephrines also means they have a higher false positive rate. However, elevation above designated thresholds (>2x the upper limit of normal) in either study suggests the presence of pheochromocytoma</p>
