The application of selective bronchial artery infusion of anticancer drug therapy in advanced lung cancer - report of 49 cases: 10 cases showed partial remission (PR), 80 cases were stable, and there was progress in two cases. The recent efficiency was 95.9% (47/49). Clinical staging with the therapeutic relationship is shown in Table 1. In terms of efficacy, the bad tim-bed stage had a relationship as follows: CR10 down, PR80 down. Step vascular type 5 down in the PR3 cases. Z cases were invalid. Multi-vessel cases were significantly better than the less vascular type, with a significant difference (P < 0.05).
In 49 cases, 2.3 cancer bamboo pathological types showed efficacy off base on lO side fine aiming lung cancer which are effective. X-ray showed the tumor completely disappeared in 6 cases (8/10) (Figure 1 and Figure 2). Inverted scales plague disappeared completely in 9 cases out of four cases showing midshipmen. Adenocarcinoma, large cell carcinoma, and unclassified lung X-ray shows the tumor has narrowed (25/49). But no cases completely disappeared (Table 2).
Water chestnut wrapped the Lou heir efficacy of two swollen Cave pathological results indicated that 2.4 prognosis of survival was less than 2 cases in June. Cases decreased from 6 to December 26, and from 12 to 18 months by l2. L0 cases of BAI underwent surgical resection with a resection rate of 204%. Tian j ridicule Pao l slightly lI_ prince Yu 2Il lying shoes groan pick fine loss of three discussions. One efficacy assessment based on chest x-ray mass and horizontal diameter product changes, calculate the product of fin rate. Continuous observation was conducted. The mass finished barrier disappears as the CR. Mass Jing 25 to 50 for the PR. S is below 25. P is the mass increases.
In this group, 49 cases, CR10 down-PR33 patients, S4, down, P2, response rate 87.8%. Recently, the efficiency was 95-9%, similar to the literature reported. Small cell undifferentiated carcinoma is the most sensitive, followed by squamous cell carcinoma. Lung metastasis cancer line BAI4 times observed for 3 months showed no increase in metastases or lesion expansion signs. This indicates that 5-FU controls lung metastasis of osteosarcoma.
49 cases experienced varying degrees of symptom change: cough disappeared (28/29), hemoptysis stopped (9/10), Shengya improved (5/8), dark cavity disappeared (6/8), Chamber Jing Yong pressure relief (5/8), atelectasis reexpansion (12/z6).
Intubation success rate is a key factor in chemotherapy efficacy. Normal bronchial artery diameter is around 1~2mm. With less than or equal to 2mm, the catheter tip finds the bronchial artery in the dark 4 to 6 vertebral level, generally carved. Blood supply in this group of patients with primary lung cancer is richer centrally than peripherally, and better on the right side than the left due to large variation of the left bronchial artery, making intubation difficult. Infusion chemotherapy drug injection speed should be slowed down for good results. Ueno long time maintaining localized high concentrations of carcinoid tumors helps improve efficacy.
In this group, after routine BAI fins, parallel surgical resection -4 cases excision saw tumor tissue degeneration to necrosis. This 10 down survival of l2 to 18 months, the survival rate was significantly higher than those without surgery. Therefore, it is considered that lung cancer line BAI should undergo early surgical resection.
Response to chemotherapy and complications: Among 49 cases, anti-nausea vomiting improved in 14 cases three days after symptomatic treatment. Subcutaneous hematoma occurred in three cases, one absorbed naturally, while two formed lumps. No vascular embolus or spinal cord transection damage was reported. Metoclopramide, furosemide, dexamethasone, and other drugs were used to prevent and control chemotherapy drug side effects. Skilled intubation techniques prevented subcutaneous hematoma. Low concentration contrast agent was used. Skilled intubation techniques prevented spinal cord damage.
