About this study
Official title: A Prospective, Multicenter, Phase III Randomized Controlled Trial Evaluating the Impact of Radical Surgery Versus Non-Surgery on Prognosis and Quality of Life in Gastric Cancer Patients With Peritoneal Metastasis After Successful Conversion Therapy (ALANO Study, CGCA2603 Study)
The goal of this clinical trial is to learn if radical surgery improves prognosis and quality of life compared with continued standard non-surgical treatment in gastric cancer patients with peritoneal metastasis who have achieved successful conversion therapy. The main questions it aims to answer are:
- Does radical surgery prolong overall survival in patients who achieve successful conversion therapy?
- Does radical surgery provide better or at least comparable quality of life and safety outcomes compared with continued standard treatment? Researchers will compare radical surgery versus continued standard systemic treatment to see whether radical surgery provides superior clinical benefit for patients after successful conversion therapy.

Participants will:
- Initial laparoscopic exploration confirms CY0P1 or CY1P1, absence of distant organ metastasis, a PCI ≤ 20, and presence or absence of ascites.
- Receive conversion therapy (chemotherapy, targeted/immunotherapy, intraperitoneal therapy, etc.) per standard guidelines, tailored to the patient's condition and molecular-pathological profile
- If clinical conversion is confirmed, undergo a second laparoscopic exploration to verify successful conversion
- If successful conversion is confirmed (peritoneal lesions cleared or markedly regressed with negative biopsy, no ascites or distant metastases, R0-resectable primary tumor, and improved patient condition), be randomized 1:1 to either the surgery group or the standard treatment group
- In the surgery group, undergo curative gastrectomy with D2 lymphadenectomy during the second laparoscopy, followed by adjuvant therapy and maintenance treatment
- In the standard treatment group, continue systemic therapy without surgery, with maintenance treatment and salvage surgery permitted if clinically indicated
- Complete quality of life questionnaires at predefined time points
- Be followed up for survival, disease progression, adverse events and medical resource use outcomes

- Gastric Cancer, Peritoneal Metastasis

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Radical Gastrectomy with D2 LymphadenectomyProcedure or surgery
Patients undergo curative gastrectomy with D2 lymphadenectomy (laparoscopic, robotic, or open) during second-look laparoscopy after successful conversion therapy. Postoperatively, they receive adjuvant systemic therapy (continuing the preoperative regimen or MDT-modified protocol) for up to 8 cycles total, followed by maintenance therapy for up to 1 year after randomization, or until disease progression, unacceptable toxicity, or withdrawal.
Standard Systemic Therapy for Advanced Gastric CancerDrug
Patients do not undergo surgery. They continue the original conversion regimen or an MDT-adjusted systemic therapy for a total of 8 cycles, followed by maintenance therapy for up to 1 year after randomization, or until disease progression, unacceptable toxicity, or withdrawal. Salvage surgery is permitted if clinically indicated.
| Study group | Role | What they receive |
|---|---|---|
| Surgery Group | Experimental | Not described Receives: Procedure: Radical Gastrectomy with D2 Lymphadenectomy |
| Standard Treatment Group | Active comparator | Not described Receives: Drug: Standard Systemic Therapy for Advanced Gastric Cancer |

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Radical Gastrectomy with D2 Lymphadenectomy and Standard Systemic Therapy for Advanced Gastric Cancer in people with Gastric Cancer and Peritoneal Metastasis, run by Hua Huang, MD, PhD at 31 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 31 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Hua Huang (+86-13816151816, huahuang@fudan.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall Survival (OS) (time frame: Up to 3 years after randomization). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2026.
