Clarify of Predictive Risk Factors of Chemotherapy-induced Liver Injury

Clarify of Predictive Risk Factors of Chemotherapy-induced Liver Injury After Therapy With Docetaxel and Cisplatin for Nasopharyngeal Carcinoma

The most common toxicity of TP (docetaxel and cisplatin) chemotherapy is chemotherapy-induced liver injury. However, patients don't always experience same chemotherapy-induced liver injury for the same drugs. Therefore, the investigators designed the present study to clarify risk factors associated with the development of severe hepatotoxicity after therapy with docetaxel and cisplatin for nasopharyngeal carcinoma (NPC).

Nasopharyngeal carcinoma (NPC) is one of the most common malignancies in southern China , with an annual incidence of 15 to 50 cases per 100,000 people. NPC is both radiosensitive and chemosensitive. Recently, many new drugs including docetaxel and cisplatin have been incorporated in the induction chemotherapy phase of NPC. The most common toxicity of TP (docetaxel and cisplatin) chemotherapy is chemotherapy-induced liver injury, and appropriate management of these toxicities can help patients improve tolerance for chemotherapy. However, patients don't always experience same chemotherapy-induced liver injury for the same drugs. Therefore, it is important to determine the risk factors to predict chemotherapy-induced liver injury. The investigators designed the present study to clarify risk factors associated with the development of severe hepatotoxicity after therapy with docetaxel and cisplatin for nasopharyngeal carcinoma (NPC).

Patients with advanced nasopharyngeal carcinoma scheduled to receive the first line, first cycle TP (docetaxel and cisplatin) chemotherapy

White blood cell level (cells/L) and liver function (such as ALT, AST, ALP, and bilirubin levels) will be tested before (1-3 days) and after (21 ± 3 days) first cycle of chemotherapy, and the relationship of white cell level fluctuation and liver injury will be investigated.

Albumin (g/L) and liver function (such as ALT, AST, ALP, and bilirubin levels) will be tested before (1-3 days) and after (21 ± 3 days) first cycle of chemotherapy, and the relationship of albumin fluctuation and liver injury will be investigated.

Hemoglobin (g/L) and liver function (such as ALT, AST, ALP, and bilirubin levels) will be tested before (1-3 days) and after (21 ± 3 days) first cycle of chemotherapy, and the relationship of hemoglobin fluctuation and liver injury will be investigated.

Blood platelet (cells/L) and liver function (such as ALT, AST, ALP, and bilirubin levels) will be tested before (1-3 days) and after (21 ± 3 days) first cycle of chemotherapy, and the relationship of blood platelet fluctuation and liver injury will be investigated.

The age(years) will be recorded when the therapy starts. The liver function (such as ALT, AST, ALP, and bilirubin levels) will betested before (1-3 days) and after (21 ± 3 days) first cycle of chemotherapy. The relationship of age and liver injury will be investigated.

The height (kg) will be recorded when the therapy starts. The liver function (such as ALT, AST, ALP, and bilirubin levels) will betested before (1-3 days) and after (21 ± 3 days) first cycle of chemotherapy. The relationship of height and liver injury will be investigated.

Inclusion Criteria: Patients with advanced nasopharyngeal carcinoma. Patients scheduled to receive the first line, first cycle TP (docetaxel and cisplatin) chemotherapy. Normal liver function biomarkers including ALT,AST,ALP,TBIL before recruitment. Minimum age of 18 years. Life expectancy at least 3 months. Exclusion Criteria: Patients previously received chemotherapy Patients who have liver metastases. Patients who take other drugs that may affect liver function
