Advanced driver gene-negative non-small cell lung cancer is generally considered incurable, and treatment aims to prolong patient survival. Recently, however, a new definition “oligometastasis” has been proposed, which refers to the appearance of no more than 5 metastatic lesions in up to 3 different organs. The emergence of this concept has changed the traditional treatment model. Many studies have shown that standard systemic therapy combined with local therapy (radiotherapy, surgery, thermal ablation, etc.) can effectively prolong the survival time of these patients. This article reviews the clinical studies on the efficacy, toxicity, and beneficiary population of local radiotherapy combined with systemic therapy in driver gene-negative oligometastatic non-small cell lung cancer, and provides further reference for clinical decision-making.
Objective To observe the toxic and side effects during the continuous hyperthermic peritoneal perfusion chemotherapy (CHPPC).Methods Abdominal paracentesis and catheterization were performed under ultrasound guidance, then CHPPC was carried out, which was in temperature of 42-44 ℃ for 1 h. The changes of body temperature, heart rate, blood pressure, saturation of blood oxygen and respiratory frequency were recorded in 109 patients during and after perfusion, meanwhile symptoms and physical signs of abdominal region and system status such as abdominal tenderness, rebound tenderness were observed. Results There were no significant differences of body temperature, heart rate, blood pressure, saturation of blood oxygen or respiratory frequency between before and after perfusion (Pgt;0.05). There were 25 patients with abdominal pain, but in which only 3 patients with symptoms of acute abdomen, 26 patients with gastrointestinal symptoms, 20 patients with myelosuppression, and others (22 cases) with aches of puncture position which were released by symptomatic treatment. Conclusion There are less toxic and side effect and better tolerance in patients with CHPPC application 1 month after operation.
