March 19, 2024 updated by: EBG MedAustron GmbH
"Spot-Scanning Based Hypofractionated Proton Therapy for Low and Intermediate Risk Prostate Cancer" "Hypofraktionierte Protonentherapie Mit Spot-Scanning-Technik Bei Prostatakarzinom Mit Niedrigem Oder Mittlerem Risiko"
This prospective study assess the effectiveness and safety of hypofractionated proton radiotherapy in the treatment of intermediate and low risk prostate cancer.

Intervention / Treatment
Detailed Description
The purpose of this study is to assess the effectiveness and safety of spot-scanning based hypofractionated proton radiotherapy for the treatment of intermediate and low risk prostate cancer.
The treatment effectiveness is defined as freedom from biochemical failure.
Treatment safety will be documented with acute and late morbidity assessments.
Dose volume relationships for late side effects in organs at risk surrounding the prostate will be calculated from the dose volume histogram parameters assessed during treatment planning.
Patient assessed Quality of life data including sexual function will be collected to increase our understanding how the reduction of normal tissue irradiation with proton therapy with subsequent decrease in functional impairments will overall affect the patient's life.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
18 years and older (Adult, Older Adult)
Accepts Healthy Volunteers
No
Description
Inclusion Criteria:
- Pathological (histologically) proven diagnosis of prostatic adenocarcinoma
- Clinical stage T1-T2b
- Prostate specific antigen (PSA) ≤ 20 ng/mL
- Gleason Score ≤ 7
- Eastern Cooperative Oncology Group (ECOG) Performance status 0-2
- Clinically negative lymph nodes evaluated by imaging (pelvic +/- abdominal CT or MRI scan)
- Any patient with lymph nodes > 1.0 cm maximum diameter requires further studies to address eligibility. Positron emission tomography (PET)-CT is recommended for lymph nodes > 1.0 cm. Positive PET-CT indicates malignant involvement. Hence, the patient will be staged as "high-risk" and therefore declared ineligible for study participation. Negative PET-CT in lymph nodes 1.0-1,5 cm indicates non-involvement and thus eligibility. Negative PET-CT in lymph nodes > 1.5 cm is equivocal and requires additional work-up, preferably by biopsy.
- Patients must be 18 years of age or older. There is no upper age limit.
- Patient must be able to provide study-specific informed consent prior to study entry.
- Willingness and ability to complete the Expanded Prostate Cancer Index Composite (EPIC) Questionnaire to assess Quality of Life.
- Previously initiated Androgen Deprivation Therapy (ADT) is acceptable.
- Patients with history of chronic bowel diseases may be included.
- Patients with previous Transurethral Resection of the Prostate (TURP) performed for urinary retention may be included.
Exclusion Criteria:
- Prior radiotherapy to the pelvic area.
- Prior prostate cancer therapy such as: prostatectomy, cryotherapy or hyperthermia.
- Prior systemic therapy (chemotherapy) for prostate cancer.
- Concurrent cytotoxic chemotherapy for prostate cancer.
- Evidence of distant metastases.
- Regional lymph node involvement.
- International Prostate Symptom Score (IPSS) > 20
- Hip prosthesis
- Second invasive malignancy (except of basal cell and squamous cell carcinoma of the skin in situ) if not controlled within last two years.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: Proton Therapy of Prostate Cancer
Patients with low and intermediate risk are included. The following interventions are performed:
|
The EPIC questionnaire is used to evaluated the Quality of life of the patients including the sexual function.
After the applied daily fraction, x-ray imaging will be repeated daily to assess for intra-fraction motion of the prostate.
For the assessment of interfraction target and organs at risk movement.
Conebeam CT as soon as it becomes available will be performed 5 x/week or at each day of proton therapy before treatment application.

Change of quality of life and sexual function from Baseline following proton therapy.
The Prostate cancer-specific Health-Related Quality of Life questionnaire Expanded Prostate Index Composite (EPIC-26) will be used.
EPIC is a comprehensive instrument designed to evaluate patient function and bother after prostate cancer treatment.
EPIC-26 was developed as a short-form version of the full EPIC.
This version contains 26 item and the same 5 domains as the full version of EPIC: Urinary Incontinence, Urinary Irritative/Obstructive, Bowel, Sexual, and Hormonal.
Response options for each EPIC item form a Likert scale, and multi-item scale scores are transformed linearly to a 0-100 scale, with higher scores representing better quality of life.
