Long-term outcomes of induction chemotherapy followed by chemoradiotherapy vs chemoradiotherapy alone as treatment of unresectable head and neck cancer: follow-up of the Spanish Head and Neck Cancer Group (TTCC) 2503 Trial

Background Our previous phase-3 study (TTCC 2503) failed to show overall survival advantage of 2 induction chemotherapy (IC) regimens followed by standard concurrent chemoradiotherapy (CRT) over CRT alone in patients with unresectable locally advanced head and neck squamous-cell carcinoma (LAHNSCC). This study described the long-term survival of those patients. Materials and methods Long-term follow-up study of patients with untreated LAHNSCC assigned to IC (three cycles), with either docetaxel, cisplatin and 5-fluorouracil (TPF arm) or cisplatin and 5-fluorouracil (PF arm), followed by CRT, or CRT alone, included in the previous TTCC 2503 trial. Results In the intention-to-treat population (n = 439), the median OS times were 25.4 (95% CI, 16.8–34.4), 26.2 (95% CI, 18.2–36.6) and 25.4 months (95% CI, 17.4–36.0) in the TPF-CRT, PF-CRT and CRT arms, respectively (log-rank p = 0.51). In the per-protocol population (n = 355), patients with larynx–hypopharynx primary tumors treated with IC (TPF or PF) followed by CRT had a longer median PFS than those who received CRT alone. Moreover, patients with ECOG 0 treated with IC (TPF or PF) followed by CRT had a better TTF than those with CRT alone. There were no statistically significant differences in terms of OS, PFS or TTF, according to the tumor load or affected nodes. Conclusion After a long follow-up, the TTCC 2503 trial failed to show the benefit of IC-CRT in unresectable LAHNSCC regarding the primary end point. However, fit patients with ECOG 0 and primary larynx–hypopharyngeal tumors may benefit from the use of IC if administered by an experienced team (AU)

Necrosis ósea avascular (NOA) de cabeza femoral en paciente con enfermedad de Hodgkin (EH) tratado con quimioterapia / Femoral head avascular osteonecrosis,(AON) in patient with Hodgkin disease (HD) treated with chemotherapy

Propósito: Descripción de un caso de NOA bilateral de cabeza femoral como complicación del tratamiento con quimioterapia de la EH. Valoramos la necesidad de un diagnóstico precoz de esta complicación. Material y métodos: Varón de 28 años diagnosticado de EH tratado con quimioterapia. Presenta NOA bilateral de cabeza femoral a los 10 meses de finalizado el tratamiento. Conclusiones: El seguimiento en pacientes con EH tratados con quimioterapia mediante radiografía simple de las articulaciones coxofemorales, puede ser útil en el diagnóstico precoz de la NOA (AU)

Interleukin-2 (IL2), as a modifier of the biological response, has been intravenously used in patients with advanced cancer associated or not to LAK cells or tumor infiltrating lymphocytes. In different neoplasias positive results have been obtained, being effective in melanoma and renal cancer. There are still, at present, many questions to be answered and multiple research lines are currently open. The association with other cytokines and new chemotherapy protocols grant new therapeutic possibilities.
