Efficacy and Safety of Precision Therapy in Refractory Tumor

Efficacy and Safety of Precision Therapy in Refractory Tumor (Long March Pathway)

This study is intended to evaluate efficacy and safety of targeted precision therapy in patients with refractory tumor, including rare tumor without standard recommended treatment and common tumor after multiple line of therapy.

The individuals recruited in the present study are with solid tumor, mainly including two parts: first, rare tumor without standard recommended treatment such as atypical fibrous histiocytoma; second, common tumor after multiple line of therapy such as lung cancer, gastric cancer, colorectal cancer, etc. All patients have no any standard therapy based on NCCN guideline when recruiting. Next-generation sequence was used to detect druggable molecular event including gene mutation, gene fusion, amplification, etc. Then patients with molecular events were treated with corresponding targeted drug and followed-up, and not limited tumor type. PD-1/L1 inhibior plus anti-angiogenic agent was used in patients without durgguable targets. The efficacy and safety of these regimens were evaluated.

Inclusion Criteria:

• Malignant solid tumors diagnosed histologically;
• Common solid tumor patients have no any standard choice after multiple line of therapy; Rare solid tumor did not have any standard recommended treatment;
• Expected survival ≥ 1 month;
• ECOG / PS score: 0-2, and the main organ function to meet the following criteria: HB ≥ 90g / L, ANC ≥ 1.5 × 109 / L, PLT ≥ 80 × 109 / L,BIL <1.5 times the upper limit of normal (ULN); Liver ALT and AST <2.5 × ULN and if liver metastases, ALT and AST <5 × ULN; Serum Cr ≤ 1 × ULN, endogenous creatinine clearance ≥50ml/min

Exclusion Criteria:

• Patient still has standard treatment therapy based on NCCN guidance;
• Patient can not comply with research program requirements or follow-up;
