HD-IFX is effective in patients who have failed conventional chemotherapy including IFX (9 g/m(2)). Improved disease-free survival was achieved in 30% of patients. However, renal failure constitutes an important life-threatening complication and its development is unpredictable.
Due to the interruptions in treatment caused by influenza infections, and economic benefits of the vaccine, we suggest that inactivated influenza vaccine should be applied as two doses annually in patients with solid tumor.
The purpose of this study was to evaluate the role of combined modality treatment in patients with paediatric nasopharynx cancer (NPC). Forty-six patients with paediatric NPC were retrospectively analysed. Forty-four of 46 patients received combined modality treatment. Five-year overall survival and progression-free survivals were 70% and 72% for the whole group, and only three of 46 patients had loco-regional relapse. Complete remission was obtained in 18 of 45 patients (40%), and the overall survival (94% vs. 62% and 19%, p = 0.0009) and disease-free survivals (93% vs. 70% and 16%, p = 0.0002) were significantly better in complete responders when compared with the patients who had partial response or stable disease. The 5-year overall survival and disease-free survivals of the patients who received neoadjuvant chemotherapy (CT) and radiotherapy (RT) followed by CT were superior to the other groups (77% and 80%, respectively). The number of total CT cycles (p = 0.0001), nodal stage (p = 0.05) and treatment response (p = 0.0009) were significant prognostic factors for overall survival. The treatment type (p = 0.02), the number of total CT cycles (p = 0.0006), nodal stage (p = 0.05) and treatment response (p = 0.0002) were found as significant prognostic factors for disease-free survival. The survival of patients receiving six or more CT cycles was also significantly better than that of patients receiving less than six cycles (p = 0.0001). In patients with locally advanced paediatric NPC, CT should be added to RT to improve outcome. However, a standard protocol is yet to be identified, and further studies evaluating the addition of interferon or immunotherapy to CT and RT shall be performed.
A retrospective and prospective analysis is reported of epidemiological, clinical, and therapeutic aspects of 33 children with nasopharyngeal carcinoma who were treated in a single institution over a period of 10 years. Twenty-three male and 10 female children ranging from 9 to 17 years were referred to our center. Histopathology was WHO type 3 carcinoma in 21, WHO type 2 in 8, WHO type 1 in 1, and unclassified in 3 patients. Disease extent was T2a (n = 15), T2b (n = 2), T3 (n = 11), and T4 (n = 5); N1 (n = 5), N2 (n = 12), and N3a (n = 16). Five patients had base of skull invasion. Four patients had M1 disease on admission. Four patients were treated with irradiation only. Three patients received neoadjuvant, 4 patients received adjuvant, and 22 patients received neoadjuvant + adjuvant chemotherapy in addition to radiotherapy. Patients received 50-72 Gy to the primary tumor and involved nodes and 45-50 Gy to uninvolved regions. Chemotherapy consisted of combinations of cisplatin, fluorouracil or Adriamycin, vincristine, and cyclophosphamide. Twenty-nine patients (88%) attained locoregional control. Overall, 10 patients died with progressive disease or infectious complications, and 2 patients are still receiving therapy. Three patients are still living with multiple metastases and stable disease. Eight patients were lost to follow-up. Twelve patients are alive without relapse 3 and 63 months from diagnosis. Seven patients had 6 relapses at distant and 1 relapse at local site. The median time for first relapse was 8 months. Overall, the 5-year survival rate was 63% and disease-free survival rate was 53%. Although the locoregional control rate is high, long-term survival rates will be the real test of the impact of chemotherapy. Further studies are needed to confirm the optimal combination of effective chemotherapeutic agents and radiotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
