Functional and psychological evaluation after exclusive chemoradiation therapy in oral and oropharyngeal cancer

e17012

Purpose: The treatment of head and neck tumours often negatively affects speech, swallowing, body image and quality of life (QoL). Aim of this study was the evaluation of the impact of exclusive chemoradiation therapy (CH-RT) on QoL and psychological functioning. Patients and Methods: Twenty-eight patients, affected by a carcinoma of the oral cavity and oropharynx received exclusive CH-RT. Late effects of CH-RT and psycho-oncological assessment included: Radiation Therapy Oncology Group (RTOG) - European Organisation for Research and Treatment of Cancer (EORTC) late radiation morbidity scoring system, DISCHE morbidity recording scheme, Hospital Anxiety and Depression Scale (HADS), Montgomery Asberg Depression Rating Scale (MADRS), Mini Mental Adjustment to Cancer (MINI MAC), and EORTC QoL Head and Neck 35. Results: After a median follow-up of 42 months (range 12–60 months) moderate-severe late toxicity was as follows: taste impairment (89.20%), salivary function (82.12%), subcutaneous tissue (7.08%). Concerning dysphagia 39% of patients complained some discomfort, 28% had a more severe toxicity whereas 7% could not have an oral feeding; patients with severe dysphagia showed higher levels of anxiety (p < 0.05): dysphagia influences the QoL, fatigue and physical-social functioning. Rates of depression and anxiety were generally low: 78.6% of our sample did not show clinical relevant anxious symptoms and 82.1% of patients did not reach the threshold of an overt depression. Just a fair concordance in rate of depression between self- and hetero-evaluated scale was observed, with higher rates relieved by MADRS compare to HADS depression subscale using 8 or 10 cut-off (Cohen's k test = 0.401) Conclusions: Our data suggest low rates of anxiety and depression, in patients treated with CH-RT, with a different evaluation between self-evaluative and hetero-evaluative scales.

Induction chemotherapy with cisplatin and epirubicin followed by radiotherapy and concurrent cisplatin in locally advanced nasopharyngeal carcinoma observed in a nonendemic population

e17040

Background: Chemoradiotherapy (CRT) represents the main therapy choice in the treatment of locoregionally advanced nasopharyngeal carcinoma (NPC). Aim of this study was the clinical evaluation of neoadjuvant chemotherapy (NACT) followed by CRT in a non endemic population affected by advanced NPC. Methods: Patients with locoregionally advanced NPC were treated with three cycles of induction chemotherapy (CHT) with cisplatin (100 mg/m2) plus epirubicin (90 mg/m2), followed by cisplatin (100 mg/m2) and concomitant radiotherapy (70 Gy). Results: In 40 patients treated with such protocol, after the completion of induction CHT and CRT we observed the objective response rates of 90% and 100% respectively. Treatment tolerability and toxicity were easily controllable. With a median follow-up time of 54.5 months 3- and 5-years disease-free survival was 75% and 65.4% and 3- and 5-years overall survival was 84% and 77.5%. 3- and 5-years loco-regional control was 82.4% and 70.3%, and 5-years distant metastases-free survival was 75%. Conclusions: NACT with cisplatin and epirubicin followed by concomitant CRT represents a feasible, efficient treatment for patients with advanced NPC. This regimen ensures an excellent locoregional disease control and overall survival with a low incidence of distant metastases.

Pharmacokinetic evaluation of gemcitabine and 2',2'-difluorodeoxycytidine-5'-triphosphate after prolonged infusion in patients affected by different solid tumors

BACKGROUND

The study determined pharmacokinetic parameters, toxicity profile and preliminary clinical activity of gemcitabine administered i.v. at different infusion rates in patients with a range of solid tumors.

PATIENTS AND METHODS

Twenty patients were enrolled for both pharmacokinetic and clinical studies. Gemcitabine 300 mg/m(2) was administered during 1 h, 2 h or 3 h, and as a conventional dose of 1000 mg/m(2) during 30 min infusion. Administration was on days 1, 8 and 15 every 4 weeks.

RESULTS

Patients were randomly assigned to one of the four arms. After 30 min infusion of 1000 mg/m(2) gemcitabine the plasma concentration remained above the saturation level of 10-20 microM, whereas after 1, 2 or 3 h infusion 300 mg/m(2) gemcitabine it remained below the saturation level for most of the time (being in the range 2.5-10 microM). Gemcitabine triphosphate was determined in the four arms in white blood cells; for infusion times from 0.5 to 3 h there was a progressive enhancement of gemcitabine triphosphate levels. In all evaluable patients the toxicity was mild, myelosuppression being the main toxicity. No grade 3 or 4 toxicities occurred. Clinical response was similar in patients receiving 300 mg/m(2) gemcitabine in 2 and 3 h and in the 1000 mg/m(2) arm.

CONCLUSIONS

300 mg/m(2) gemcitabine during 3 h infusion produced the highest accumulation of gemcitabine triphosphate. Thus, to achieve the highest possible gemcitabine triphosphate level, prolonged infusion time would appear to be more important than a high dose administered as a short infusion. However, there was no substantial difference in toxicity or antitumoral activity in the all different patient groups.
