Lung cancer is the cancer with the highest morbidity and mortality in the world
At the 2021 ASCO annual meeting, data from multiple clinical trials including immunotherapy combined with chemotherapy/immunization were updated, summarized as follows:
▌Adjuvant treatment: "T drug" delays early relapse of patients
▌Adjuvant treatment: "T drug" delays early relapse of patients
In recent years, immunotherapy has achieved remarkable results in advanced NSCLC, which has changed the treatment mode of such patients
.
Now, researchers are beginning to explore whether immunotherapy as a neoadjuvant/adjuvant therapy can benefit patients with early-stage NSCLC

Now, researchers are beginning to explore whether immunotherapy as a neoadjuvant/adjuvant therapy can benefit patients with early-stage NSCLC
.
In the IMpower010 clinical trial, 1280 patients with high-risk early NSCLC after complete resection were enrolled.
After 4 weeks of chemotherapy, 1005 patients were randomized to receive atilizumab or the best supportive treatment

The results show that:
In patients with stage II-IIIA with PD-L1 ≥ 1%, the median disease-free survival (DFS) of atilizumab had not yet reached at the end of the data statistics, compared with 36.

These data indicate that adjuvant atelizumab therapy can significantly prolong the disease-free survival of patients with stage II-IIIA lung cancer, especially in patients with tumors with high PD-L1 expression
.
In addition, adjuvant therapy has a long-lasting effect, and can still reduce the recurrence rate of patients 2 years after stopping the drug

▌Neo-adjuvant therapy: "O drug" for early lung cancer
▌Neo-adjuvant therapy: "O drug" for early lung cancer
Nivolumab ("O drug") is the first PD-1 immune checkpoint inhibitor approved globally, and was first launched in 2014
.
.
CheckMate -816 is a phase 3 randomized, open-label, multicenter trial that evaluates the possibility of nivolumab plus chemotherapy as a neoadjuvant treatment compared with chemotherapy alone
.
.
The results show that:
Among patients with resectable NSCLC, the complete pathological response rate (PCR) of nivolumab plus chemotherapy as the neoadjuvant treatment group before surgery was significantly higher than that of neoadjuvant chemotherapy, 24% and 2.
2%, respectively;

The main pathological response rate (MPR) of the treatment group and the control group were 36.

In addition, as a neoadjuvant treatment, nivolumab + chemotherapy did not adversely affect the time and feasibility of surgery, and the treatment was tolerable without increasing surgical complications
.
.
These results support nivolumab combined with chemotherapy as a potential neoadjuvant treatment option for patients with non-metastatic, resectable NSCLC

▌Five-year data update: 43% of patients have long-lasting benefits!
▌Five-year data update: 43% of patients have long-lasting benefits!
Generally, patients with stage III NSCLC have a median survival time of only one year due to the inability to surgically remove the tumor, and the 5-year survival rate is low

At this ASCO conference, the "I drug" Duvalizumab for the treatment of phase III, non-resectable non-resectable lung cancer phase 3 PACIFIC clinical trial data was updated again
.
.
The results show that:
The median OS of the duvalizumab group was 47.

4 months (one and a half years) longer than the 29.

Since 2017, this study has updated four sets of data, each time bringing new surprises
.
At the same time, these data also further verify that duvalizumab can bring significant and lasting benefits to patients

In addition, the two-year follow-up data of the CheckMate -9LA study of "O drug" nivolumab combined with "Y drug" ipilimumab was also announced at this conference
.
.
The results show that:
Compared with receiving four cycles of chemotherapy alone, the median overall survival of nivolumab + ipilimumab + two cycles of chemotherapy was 15.

11 months, and the 2-year OS rate of the two groups was 38%.

Moreover, regardless of the patient's PD-L1 expression level and tumor histological type, clinical benefits were observed
