Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Into a set of 25 cases of the gastric carcinoma confirmed by pathology or gastroesophageal junction adenocarcinoma (cT4 and/or N + M0, Multi-Disciplinary Team thought line to perioperative treatment) patients, preoperative accept four cycle by bead a resistance + sintilimab + capecitabine plus oxaliplatin into new adjuvant chemotherapy, because PD1 antibodies distance between surgery time interval is the lack of clinical data, judging by the researchers is 4 cycles of chemotherapy combination of sintilimab .The patient was able to undergo D2 radical surgery.Pathological examination was carried out to observe the pCR and the infiltration rate of immune cells.After the operation, patients continued to receive 4 cycles of capecitabine + oxaliplatin adjuvant therapy, and the total number of chemotherapy cycles was 8 cycles.Disease-free survival time and safety of treatment were observed, and OS, ORR and quality of life of all patients were followed up.

Phase

Phase

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

Eligibility Criteria

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pathological complete response (pCR) rate
Time Frame: immediately after surgery
Complete pathological response can be determined if no tumor lesion remains or only carcinoma in situ remains in the Complete pathological response can be determined if no tumor lesion remains or only carcinoma in situ remains in the Complete pathological response can be determined if no tumor lesion remains or only carcinoma in situ remains in the surgical specimens (see WHO solid tumor efficacy criteria
immediately after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Disease free survival(DFS)
Time Frame: From the date of first treatment dose until documented disease progression or death from any cause. whichever occur first, assessed up to 30 months
The interval between the dates of the first dose of trial treatment until first documentation of disease progression or death, whichever occurs first. Patients with new non-breast cancer malignancy must continue to be followed for progression of the original breast cancer. For patients without progression, follow-up is censored at the date of last disease assessment without progression, unless death occurs within 12 weeks following the date last known progression-free, in which case the death will be counted as a DFS event.
From the date of first treatment dose until documented disease progression or death from any cause. whichever occur first, assessed up to 30 months
