7.

Primary local treatment

Management decisions should be made after all options

have been discussed with a multidisciplinary team (includ-

ing urologists, radiation oncologists, medical oncologists,

pathologists, and radiologists), and after the balance of

benefits and side effects of each therapy modality has been

considered together with the patient.

8.

Active surveillance and watchful waiting

Active surveillance (AS) aims to reduce overtreatment in

men with very low-risk PCa, without compromising

opportunities for cure, whereas watchful waiting (WW) is

a conservative management for frail patients until the

possible development of clinical progression leading to

symptomatic treatment. The major differences between

these two modalities are detailed in

Table 7

.

Mortality from untreated screen-detected PCa in

patients with GS 5–7 can be as low as 7% at 15 yr follow-

up

[37] .

An RCT was unable to show an OS and CSS

difference at 10 yr between RP and WW in 731 men with

screen-detected clinically organ-confined PCa

[38]

. Only

patients with intermediate risk or with a PSA

>

10 ng/ml

had a significant OS benefit from RP (hazard ratio [HR]:

0.69 [0.49–0.98] and 0.67 [0.48–0.94], respectively). A

population-based analysis in 19 639 patients aged 65 yr

who were not given curative treatment found that in men

having a Charlson Comorbidity Index score 2, tumour

aggressiveness had little impact on OS at 10 yr

[39]

. These

data highlight the potential role of WW in some patients

with an individual life expectancy

<

10 yr.

A systematic review summarised the available data on

AS

[40]

. There is considerable variation between studies

regarding patient selection, follow-up policies, and when

active treatment should be instigated. Selection criteria for

AS include clinical T1c or T2a, PSA

<

10 ng/ml, and PSA

density

<

0.15 ng/ml per ml (even if still controversial

[41]

),

fewer than two to three positive cores with

<

50% cancer

involvement of every positive core, GS 6. Extraprostatic

extension or lymphovascular invasion should not be

considered for AS

[42]

. Rebiopsy to exclude Gleason

sampling error is considered important

[41]

, and mpMRI

has a major role based on its high NPV value for lesion

upgrading and to exclude anterior prostate lesions

[43] .

Fol-

low-up in AS is based on repeat biopsy

[41]

, serial PSA

measurements, and DRE, the optimal schedule remaining

unclear. Strategies how to incorporate mpMRI within this

follow-up are evolving but are not yet established. The

decision to switch to an active treatment is based on a

change in the inclusion criteria (T stage and biopsy results).

The use of a PSA change (especially a PSA doubling time

<

3

yr) remains contentious based on its weak link with grade

progression. Active treatment may also be triggered upon a

patient’s request

[44]

.

9.

Radical prostatectomy

The goal of RP is eradication of PCa while preserving

continence and, whenever possible, potency. It is the only

treatment for localised PCa to show a benefit for OS and CSS,

compared with WW. Patients should not be denied this

procedure on the grounds of age alone

[21]

provided they

have at least 10 yr of life expectancy and are aware that

increasing age is linked to increased incontinence risk.

Nerve-sparing RP can be performed safely in most men with

localised PCa. High risk of extracapsular disease, such as any

cT2c or cT3 or any GS

>

7, are usual contraindications. An

externally validated nomogram predicting side-specific

extracapsular extension can help guide decision making

[45]

. mpMRI may be helpful for selecting a nerve-sparing

approach because it has good specificity (0.91; 95% CI, 0.88–

0.93) but low sensitivity (0.57; 95% CI, 0.49–0.64) for

detecting microscopic pT3a stages

[46]

. But the experience

of the radiologist remains of paramount importance.

Lower rates of positive surgical margins for high-volume

surgeons suggest that experience and careful attention to

surgical details can improve surgical cancer control

[47]

and

lower the complication rate.

There is still no evidence that one surgical approach is

better than another (open, laparoscopic, or robotic), as

highlighted in a formal systematic review. Robot-assisted

prostatectomy is associated with lower perioperative

morbidity and a reduced positive margins rate compared

with laparoscopic prostatectomy, although there is consid-

erable methodological uncertainty. No formal differences

exist in cancer-related continence or erectile dysfunction

outcomes

[48]

.

Pelvic lymph node dissection

The individual risk of finding positive lymph nodes can be

estimated using externally validated preoperative nomo-

grams such as that described by Briganti

[49]

. A risk of nodal
