Craniomaxillofacial osteosarcoma - The role of surgical margins.

BACKGROUND: Osteosarcomas (OS) in the craniomaxillofacial (CMF) region are typically diagnosed at later age than long-bone OS, but they are reported to have better 5-year survival. Curative treatment warrants wide surgical resection, which is often not possible in the CMF region. The purpose of this article is to present a nationwide series of CMF in Finland to discuss the role of surgery. PATIENTS AND METHODS: All 21 CMF OS patients managed in Finland from 1992 to 2009 were included. The mean age was 40 years (range 15-72). Data on patient and tumor characteristics, treatment modalities, and survival were recorded. All patients had a minimum follow-up of 5 years or until death. RESULTS: OS was evenly represented in the mandible and maxillary bones, which together constituted 76% of all sites. Surgery with curative intent was carried out in 20 patients. Clear margins were achieved in only five cases. Eight (40%) of these 20 patients died due to OS, and their average survival time was 1.3 years. Seven (35%) out of the 20 patients received radiotherapy due to close/intralesional surgical margins, and four of them did not develop recurrences during the follow-up. CONCLUSIONS: The results suggest that postoperative radiotherapy may alter the prognosis in CMF OS, particularly in cases with close or intralesional margins. This may increase the survival rates achieved by prompt action in performing radical surgery.

End-of-life care pathway of head and neck cancer patients: single-institution experience.

BACKGROUND: Studies on palliative care of head and neck cancer (HNC) patients are scarce although the affected patient population is quite large. OBJECTIVE: To evaluate the role of a specialised palliative-care pathway of HNC patients. PATIENTS AND METHODS: Data on all HNC patients who were treated at the Helsinki University Hospital Palliative Care Center during 1 year were retrospectively reviewed. The analysis comprised 60 patients (49 males; mean age 67 years; range 28-88). All patients had a minimum follow-up of 1 year or until death. RESULTS: Fifty-nine (98%) out of the 60 patients died during the follow-up period. Median survival after diagnosis was 11 months (range 3 weeks-11.9 years) and after withholding disease-specific therapies 3 months (range 0-16). Thirty-three (55%) patients received palliative radiotherapy, 27 (45%) had PEG tube and 17 (28%) tracheostomy. Thirty-seven (66%) patients visited an emergency department (ED) (median 1.3 visits; range 0-6) and 21 (35%) were hospitalised at the university hospital during the palliative period. The most common severe complications were infection (also the most common reason for ED visits and hospitalisation), bleeding (four massive airway bleedings with one death), delirium and airway obstruction (one emergency tracheostomy). Twelve (35%) out of the 34 patients who were referred to specialised home care died at home as compared with three (12%) out of the 26 patients not supported by a specialised home-care team. CONCLUSIONS: Severe complications leading to an emergency unit visit and hospitalisation are common among HNC patients in their relatively short palliative period reflecting the need for early-integrated palliative care. Collaboration with a specialised palliative home-care team seems to increase end-of-life care at home.

Hearing and tinnitus in head and neck cancer patients after chemoradiotherapy.

Head and neck cancer patients treated with high-dose cisplatin and radiotherapy will suffer from hearing deficits. The current low-dose regimen seldom causes hearing threshold decrease. Tinnitus in this patient population has not been investigated earlier. We aimed to evaluate the possible ototoxicity of low-dose (40 mg/m(2)) weekly administered cisplatin with concomitant radiotherapy. Twenty-two patients with locally advanced head and neck cancer were prospectively recruited to participate the study after treatment recommendation for chemoradiotherapy with low-dose cisplatin and intensity-modulated radiotherapy. They filled in a Tinnitus Handicap Inventory and undertook audiologic evaluations before and after treatment. Ototoxicity was determined by >10 dB threshold shift at frequencies 4 and 8 kHz or in pure tone average. A historical cohort of nine patients treated with high-dose (100 mg/m(2)) cisplatin and radiotherapy was used for comparison. After treatment, study patients demonstrated no significant changes in their hearing over frequencies 0.5-4 kHz, and the threshold shifts were minor at 4 and 8 kHz. More than 50 % of patients reported no tinnitus after treatment and the remainder only had slight to moderate tinnitus causing no interference with their daily activities. In contrast, five of the nine patients having received high-dose cisplatin reported disturbing tinnitus. Further, changes in pure tone averages were exhibited in three of these patients and six had significant threshold shifts at 4 and 8 kHz. Head and neck cancer patients treated with concomitant intensity-modulated radiotherapy and low-dose cisplatin seem to experience only minor audiological sequelae and therefore, these patients appear to require no routine audiological monitoring. Such evaluation could be performed only when needed.

Trends in the 15D health-related quality of life over the first year following diagnosis of head and neck cancer.

Management of head and neck cancer influences both physical and mental wellbeing. Measuring the health-related quality of life (HRQoL) is important, as various treatment modalities are associated with significant morbidity and mortality. In this prospective cohort study, we tested the feasibility of the generic 15D HRQoL instrument in 214 head and neck cancer patients managed with surgery, definitive (chemo)radiotherapy, or with combined modality treatment. HRQoL was assessed at baseline and three times after treatment onset during 1 year, and compared with that of general population standardized for age and sex. At baseline, the patients' mean 15D score was significantly worse compared with general population. Overall HRQoL was at lowest at 3 months after treatment onset, it gradually improved towards 12 months but never reached baseline levels. The dimensions "vitality", "distress", "depression" and "sexual activity" showed marked deterioration at 3 months after the treatment onset, but improved gradually during 12 months. The 15D instrument seems useful for evaluation of HRQoL of head and neck cancer patients. Dimensions reflecting mental wellbeing improved gradually after 3 months, but they seldom reached baseline levels. The support for patients at the time of diagnosis, during treatment, and recovery is emphasized.

A two-decade experience of head and neck paragangliomas in a whole population-based single centre cohort.

Paragangliomas are rare neuroendocrine tumours arising from neural crest-derived tissue. In the head and neck region typical locations are the carotid bifurcation, vagal nerve or jugulotympanic region. Paragangliomas are normally benign, and malignant transformation is rare. During the past decade the understanding of the genetic and molecular aetiology has had an important clinical impact on the management of PGs. This is a retrospective review of all histologically verified paragangliomas diagnosed and managed at an academic tertiary care referral centre between 1990 and 2010. Data on age, sex, symptoms, tumour location, management and follow-up were recorded. There were 64 patients with 74 tumours. Thirty-six per cent of the tumours were located in the carotid body region, 48 % in the jugulotympanic region and 15 % in the vagal nerve. One tumour was located in the dorsal neck. Most (95 %) of the patients were treated primarily with surgery and with curative intent. Definitive radiation therapy was primarily given to two patients. Recurrent or residual tumours were treated with surgery in three patients and with radiation therapy in nine patients. The typical long-term post-operative sequel was vocal cord paralysis. Local recurrence was found in 6 % of patients. Symptoms and findings related to paragangliomas are variable and management should be individualized. Surgery remains the primary choice of the current treatment options, but often is challenging and warrants a multidisciplinary approach. We present an algorithm on the management of head and neck paragangliomas based on current knowledge.

Health-related quality of life of head and neck cancer patients with successful oncological treatment.

Oncological treatment of head and neck carcinoma is associated with high morbidity. Measuring of health-related quality of life (HRQoL) is crucial in this patient group but there is no consensus on which measure would be preferable to be used. In this study, HRQoL was measured with the generic 15D, which has not been used before for assessing this patient population. It is a prospective cohort study among 64 patients with laryngeal, pharyngeal or nasal cavity carcinoma treated with definitive (chemo) radiotherapy between November 2007-July 2012. HRQoL was assessed with the 15D before and at 3, 6 and 12 months after the treatment onset. HRQoL results of the patients were compared with those of the age-standardized general population. Overall HRQoL declined significantly during the first 3 months after the treatment onset but then gradually improved towards the end of the follow-up. At baseline or at 12 months, no significant differences were detected in overall HRQoL between the patients and the general population. Dimensions reflecting mental well-being showed gradual improvement, exceeding the baseline scores at the end of the follow-up. Nevertheless, on these dimensions, the patient group presented with consistently lower scores compared with the general population. The mean HRQoL was lower among patients with pharyngeal carcinoma compared with the laryngeal carcinoma patients. The 15D instrument is feasible for evaluation of HRQoL in oncologically treated head and neck cancer patients. It seems to detect differences among different patient subgroups. Multidisciplinary supportive management of this patient population is recommended to ensure improved mental well-being.

Repopulation during radical radiotherapy for T1 glottic cancer.

BACKGROUND AND PURPOSE: Because opinions on the significance of repopulation during radiotherapy of T1 laryngeal cancer vary, we have estimated the effective rate of tumour cell repopulation during radiotherapy in patients with T1 laryngeal cancer. MATERIALS AND METHODS: One hundred seventeen consecutive patients with T1 laryngeal cancer were treated from 1982 to 1993 by radical radiotherapy alone either as continuous (n = 28) or split-course treatment (n = 89). The logit method of the linear-quadratic formula for local control at 3 years was used to examine the effect of treatment time on local control. The analysis was made for all patients to obtain a wide range of overall treatment times. RESULTS: The 3-year overall survival rate was 76% and the 3-year local control rate was 85% (range 82-88%). The local control rates were 95% (range 94-96%) for the continuous and 81% (range 75-91%) for the split-course therapy groups, respectively. The results showed a mean Dprolif value at the steepest part of the response versus time curve of 0.48 Gy/day for local control at 3 years although this was not statistically significant. The trade-off of dose required to compensate for a 1 week increase in treatment time for local control at the 90% level achieved at 3 years was calculated to be 3.5 Gy. CONCLUSIONS: The present results suggest that repopulation should be taken into account even when treating small T1 laryngeal cancer and that protraction of the overall treatment time should be avoided.
