What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether robotic surgery can be the first treatment for stage IIA/B testicular seminoma, instead of chemotherapy or radiation. The surgery removes lymph nodes in the abdomen using a robot. The goal is to see if it prevents cancer from coming back. The trial will enroll 25 men.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Robotic retroperitoneal lymph node dissection (R-RPLND) using the DaVinci robotic system
What this could lead to
If successful, this could offer a less toxic, surgery-only option for early-stage testicular cancer, reducing the need for chemotherapy or radiation.
What could go wrong
This is a small, early-phase study with only 25 participants. The surgery may not control the cancer as well as standard treatments, and relapse remains a risk.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 25 people

The number the study aims to enrol. It can still change while the study runs.

Started

Feb 2022

Expected to finish

Nov 2030

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Male participants only

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Histologically confirmed seminomatous testicular germ cell tumour with negative margins on radical orchiectomy * Lymphadenopathy in the retroperitoneum: at least one lymph node ≤5cm in size (in the transverse plane) detected on contrast CT scan or MRI (CS IIA/B; or active surveillance relapse with CS IIA/B equivalent) * CT Chest negative for metastasis * Patients qualify for this trial under the following scenarios: (1) initial diagnosis of clinical or stage IIA/B disease or (2) recurrence after surveillance for clinical stage I disease * Patients with serum tumour marker elevation are eligible if the elevated marker does not exceed the following cut-offs within 10 days of RPLND: AFP (\< 2.5 x ULN) and β-hCG (\<5 IU/L) * Curative treatment with RPLND is intended * Under the care of a uro-oncologist at Princess Margaret Cancer Centre * Willing to comply with follow-up protocol * Capable of providing informed consent Exclusion Criteria: * Retroperitoneal lymphadenopathy \>5cm in the transverse plane (CS IIC) * Metastasis to distant lymph nodes or any organ (CS III) * History of chemotherapy or radiotherapy to the retroperitoneum * Patients with previous scrotal or retroperitoneal surgery for indication other than germ cell tumour * Patients in reduced general condition, with uncontrolled intercurrent illnesses, or with life-threatening disease * Patients with psychiatric illnesses that would limit compliance with study requirements * Unsuitable for robotic surgery (determined by treating physician)
