[Cox proportion hazard model multivariate analysis of prognosis of 1,484 axillary node-negative breast cancer patients].
To study the prognosis of axillary node-negative breast cancer patients. ⋯ Parts of high risk group among axillary node-negative breast cancer patients could be identified by clinical parameters. Postoperative radiotherapy or ovarian ablation was not indicated for axillary node-negative breast cancer patients. Tamoxifen as postoperative adjuvant therapy should not be restricted to postmenopausal or ER-positive patients. The selection of high risk patients with axillary node-negative breast cancer who should receive adjuvant chemotherapy remains to be investigated at present.

Randomized Controlled Trial Comparative Study Clinical Trial[A randomized trial of tropisetron in the prophylaxis of nausea and vomiting induced by chemotherapy].
Thirty patients receiving cisplation or non-cisplatin (containing cyclophosphamide and adriamycin) chemotherapy were enrolled in a randomized, crossover study comparing the efficacy of single dose of Navoban (tropisetron, 5 mg) and Kytril (granisetron, 3 mg). The effective control of acute vomiting induced by cisplatin was achieved in 95.2% (20/21) of patients receiving Navoban and 90.5% (19/21) in those receiving Kytril. Complele control rate was 71.4% (15/21) in Navoban arm, and 81.0% (17/21) in Kytril arm. ⋯ The effective control of vomiting induced by non-cisplatin drugs was achieved in 9/9 in both arms. It is concluded that both agents are effective in the control of vomiting induced by chemotherapy. They have identical adverse effects and are well tolerated by the patients.

To assess the value of thoracoscopy in malignant pleural effusions, the procedure and results of thoracoscopy by using a fiberoptic bronchoscope and a rigid cold-light thoracoscope in 130 cases with malignant pleural effusion are reported. The overall diagnostic rate was 91.5% (119/130). The malignant pleural mesothelioma in 24 cases and metastatic cancers in 95 cases were histopathologically confirmed. ⋯ Postoperative complications included transient fever and chest pain, local subcutaneous emphysema in 6 cases and tumor seeding at thoracoscopy site in 4 cases. It is concluded that thoracoscopy is simple, safe, reliable and of high practical value in the diagnosis of malignant pleural effusions and in assessment before exploratory thoracotomy, and that transendoscopical administration of drugs for pleurodesis is a very effective method for controlling malignant pleural effusions. The efficacy of the talc poudrage is better than tetracycline and Corynebacterium parvum.

Randomized Controlled Trial Comparative Study Clinical Trial[Evaluation of staging conformity CTNM and PTNM for lung cancer].
A series of 225 consecutive lung cancer patients were prospectively randomized into study group (75 patients) and control group (150 patients), and the conformity of CTNM and PTNM staging was was evaluated. Radical mediastinal lymph node dissection was performed and in average 11.5 nodes were dissected in the study group. Only suspected metastatic lymph nodes, 3.4 in average, were dissected in the control group. ⋯ The results of the study show that at present the CTNM staging has not fully satisfied the needs of practice and requires to be further improved. The operative procedure which only dissects suspected involved mediastinal lymph nodes can not meet the needs of PTNM staging. In order to make PTNM staging accurately and evaluate the results of treatment for lung cancer, radical mediastinal lymph node dissection should be performed in every operable patient.

[Combined use of ondansetron and other anti-emetics to control cisplatin-induced nausea and vomiting].
While ondansetron is effective in the control of nausea and vomiting induced by high dose cisplatin, it has to be given in multiple doses and is very expensive. We designed a regimen of combined use of a single dose of ondansetron and dexamethasone to control acute emesis and combined use of metoclopramide, diphenhydramine and valium to control delayed emesis. The results of this regimen was compared with that of the routine treatment regimen using metoclopramide plus diphenhydramine plus valium. ⋯ The regimen increased the emesis control rate by 7.6% and 42.7% on day 1 and 2, respectively as compared to that of repeated administrations of ondansetron alone. The regimen, though not as good as expected, was still better than the routine one for the control of delayed emesis. It deserves recommendation for its better anti-emetic efficacy and lower medical expenses.
