Filter by:Currently, most protocols of nasopharyngeal carcinoma (NPC) of various research bodies such as the Radiation Therapy Oncology Group require routine elective irradiation to the retropharyngeal area and to levels II-V lymph nodal areas regardless of the status of nodal metastasis. Previous studies had confirmed that the pattern of cervical lymph node (LN) metastasis in NPC followed an orderly manner. Retropharyngeal LNs were the most commonly involved, followed by upper neck levels II, III, or VA nodes, and finally to the lower neck nodes including level IV and VB nodes; and the incidence of LN skip metastasis is rare, ranging from 0.5% to 7.9%. It was rare for NPC patients without neck LN metastases to experience neck failure after elective irradiation to levels II, III and VA. It was also confirmed that with unilateral LN metastases of higher-level LNs usually spread down ipsilateral LNs. Thus, the investigators conduct the non-inferior randomized trial to determine the value of elective neck irradiation in NPC patients with unilateral or bilateral uninvolved neck.
The purpose of this study is to determine whether endostar and IMRT is effective in the treatment of locally recurrent nasopharyngeal carcinoma patients compared with IMRT alone.
Currently, concurrent chemoradiotherapy with/without sequential chemotherapy is the standard treatment modality for intermediate risk NPC (stage II and T3N0M0) according to the National Comprehensive Cancer Network guideline. However these recommendations were based on the evidence in the two-dimensional conventional radiotherapy (2DCRT) era. The introduction of intensity-modulated radiotherapy (IMRT) in NPC treatment has brought substantial better treatment outcomes than 2DCRT. It has been questioned whether additional concurrent chemotherapy is still necessary for intermediate risk NPC within the excellent framework of IMRT. Thus, the investigators jointly conduct the first non-inferior randomized trial to determine the value of concurrent chemotherapy with cisplatin for intermediate risk NPC patients treated with IMRT. Given the results of clinical studies mentioned above,the investigators decide to adopt the concurrent regimen to be cisplatin 100 mg/m2 on day 1, 22, 43
This is a Phase Ⅲ randomized, controlled, multi-center, trial comparing cisplatin plus docetaxel to cetuximab, cisplatin, and docetaxel induction chemotherapy followed by concurrent chemoradiation in previously untreated patients metastatic nasopharyngeal carcinoma (mNPC) to determine whether the addition of cetuximab to induction chemotherapy and chemoradiation could improve therapeutic efficacy in mNPC, and investigate predictive and prognostic factors for mNPC.
The purpose of this study is to compare individualized clinical target volume (CTV) based on disease extension risk atlas and computer-aided delineation with traditional CTV in intensity modulated radiotherapy (IMRT) for nasopharyngeal carcinoma (NPC), in order to confirm the efficacy and safety.
The investigators aim to evaluate the survival benefit from triple combination of induction, concurrent and aduvant chemotherapy versus concurrent chemotherapy alone for high risk locoregionally advanced nasopharyngeal carcinoma treated with intensity-modulated radiotherapy.
This is a study of pembrolizumab (MK-3475) versus standard treatment (capecitabine, gemcitabine, or docetaxel) for the treatment of recurrent or metastatic nasopharyngeal cancer (NPC). Participants will be randomly assigned to receive either pembrolizumab or Investigator's choice of standard treatment. The primary study hypothesis is that pembrolizumab treatment prolongs Overall Survival (OS) when compared to standard treatment. With Amendment 7 (effective 2-March-2022), upon study completion, participants will be discontinued and may be enrolled in an extension study.
The investigators aim to evaluate the efficiency and toxicities of concurrent docetaxel and cisplatin with intensity-modulated radiotherapy in high risk locoregionally advanced nasopharyngeal carcinoma.
A prior phase III randomized trial showed considerable survival benefit from the combined treatment of cisplatin-based concurrent chemotherapy and two-dimensional conventional radiotherapy (2DCRT) for patients with stage II (the Chinese 1992 staging system) nasopharyngeal carcinoma. However, since intensity-modulated radiotherapy (IMRT) was known to be superior to 2DCRT in local control, progression free survival and even overall survival, it is a pivotal question whether stage II [T1N1M0 and T2N0-1M0, based on the 2010 International Union against Cancer/American Joint Committee on Cancer (UICC/AJCC) staging system] patients can still obtain significant benefit from the additional concurrent chemotherapy in the IMRT era. The investigators' retrospective study (PMID:26528755 ) indicated that low risk nasopharyngeal carcinoma (T1N1M0, T2N0-1M0 or T3N0M0, the 2010 UICC/AJCC staging system) patients who underwent IMRT could not benefit from cisplatin-based concurrent chemotherapy. Therefore, the investigators perform this randomized controlled trial to address this question, on a prudent assumption that IMRT alone was not inferior to IMRT plus concurrent chemotherapy in stage II patients.
The purpose of this randomized controlled Phase II study is to assess the efficacy of PDR001 versus investigator's choice of chemotherapy in patients with advanced nasopharyngeal carcinoma (NPC). By blocking the interaction between PD-1 and its ligands PD-L1 and PD-L2, PDR001 leads to the activation of a T-cell mediated antitumor immune response.
