Methods: Thirty-four patients were confirmed diagnosis with cancer by pathologic results. All patients were given 6MV X-ray for radiotherapy, Dt 66-70 Gy/33-35 f/6-7 w, concurrently administrated nedaplatin (30 mg/m2) once a week (6 times). Results: A total 34 patients were enrolled, of whom 33 patients were available for objective response, 1 patient of esophageal cancer quit for allergic reaction. The response rate (RR) of nedaplatin-contained therapy for nasopharyngeal carcinoma and esophageal carcinoma were 90.0% and 76.9%, respectively. The major toxic reaction was bone marrow suppression observed in 25 patients (73.5%), in which grade III aleukocytosis was observed in 3 patients (8.8%), grade III + IV thrombocytopenia in 3 patients (8.8%). And 6 patients (17.6%) showed gastrointestinal tract reaction. There were 4 patients with radiation esophagitis in the 13 patients with esophageal carcinoma. Conclusion: Nedaplatin can increase the therapeutic effect of radiation. Its incidence rate of bone marrow suppression is high, but the gastrointestinal tract reaction and renal toxicity is low and mild.展开更多

Methods: A total of 102 patients with TNBC were confirmed by histopathology. They were divided into TAC group (52 cases) and TP group (50 cases). Group TAC: Docetaxel 75 mg/m2 or paclitaxel (taxol liposome) 135 mg/m2 on all, pirarubicin 40 mg/m2 or epirubicin 75 mg/m2 on d2, cyclophosphamide 600 mg/m2 on dl; Group TP: Docetaxe175 mg/m2 or paclitaxel (taxol liposome) 135 mg/m2 on dl, cisplatin 30 mg/m2 on d2-d4, with 21 days as a cycle. All patients underwent operation after 2-4 cycles of chemotherapy. The short-term effects and toxic and adverse effects were evaluated. Results: In TAC group, 5 cases (9.6%) had pathological complete release (pCR), 35 cases (67.3%) partial release (PR), 9 cases (17.3%) stable disease (SD), and the response rate (RR) was 76.9%. In TP group, 4 cases (8%) had pCR, 32 cases (64%) PR, 5 cases (10%) SD, and RR was 72%. In 102 patients, 12 patients with tumor progression after 2 cycles of chemotherapy, included 3 cases in TAC group, 9 cases in TP group. In TAC group, 2 cases occurred atrial premature contraction; while 3 cases developed grade 2 renal injury in TP group. In TAC group, grade 3-4 hematologic toxicity and alopecia was significantly higher than that in TP group, but grade 3-4 gastrointestinal reaction rate in TP group was significantly higher than TAC group. Conclusion: TAC and TP regimens all had certain efficacy in the neoadjuvant chemotherapy for TNBC, and the toxicity reactions can be tolerated.展开更多
