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. ClinicalTrials.gov identifier NCT00261703.

SEOM clinical guidelines for the treatment of nasopharyngeal carcinoma 2013.

Nasopharyngeal carcinoma cases are not frequently encountered in our environment. Local stages are treated with radiotherapy. For advanced local stages, the association of chemotherapy with radiotherapy improves the rates of survival. In the case of metastatic disease stages, treatment requires platinum-based chemotherapy and patients may achieve a long survival time.

SEOM clinical guidelines for the treatment of head and neck cancer (HNC) 2013.

Head and neck cancer represents 5 % of oncologic cases in adults. Early stage treatments are local with surgery and/or radiotherapy. For locally advanced stages, treatment requires radiotherapy combined with platinum-based drugs or cetuximab. Induction chemotherapy should be considered for selected cases. In the case of metastatic disease, adjuvant or palliative treatment is based on platinum agents and cetuximab.

Clinical outcome in patients with intramedullary spinal cord metastases from lung cancer.

Intramedullary spinal cord metastases (ISCM) are uncommon and present with rapidly progressing neurological deficits. The objective of this study was to determine the rate, duration of neurological response and survival after radiation therapy. We have retrospectively reviewed the clinical outcome of six cases with a diagnosis of ISCM from primary lung cancer, non-small cell (NSCLC) (n=3) and small cell (SCLC) (n=3). Total radiation dose ranged from 27 Gy/5 fr to 40 Gy/20 fr. Ambulation was preserved in 3 patients and partially recovered in one. Five out of the six patients (83%) showed improvement in neurological signs/symptoms with a mean duration of 17.2 days (max: 40 days; min: 6 days). Median survival time was 5 months (confidence interval (CI) 95%: 0-12) for NSCLC and 5 months (CI 95%: 4-6) for SCLC. Although radiation response rate is high, the interval free of neurological progression is very short. A therapeutic approach should be considered for each individual.
