Improved depiction of pterygopalatine fossa anatomy using ultrahigh-resolution magnetic resonance imaging at 7 tesla

Purpose. To study the anatomy of the pterygopalatine fossa (PPF) using ultrahigh-resolution magnetic resonance imaging. Methods. A human cadaveric tissue block containing the pterygopalatine fossa was examined on a clinical 7-Tesla magnetic resonance imaging system. Subsequently, cryosections of the tissue block were created in a coronal plane. The cryosections were photographed and collected on adhesive tape. The on-tape sections were stained for Mallory-Cason, in order to detail the anatomic structures within the fossa. Magnetic resonance images were compared with surface photos of the tissue block and on-tape sections. Results. High-resolution magnetic resonance images demonstrated the common macroscopic structures in the PPF. Smaller structures, best viewed at the level of the operation microscope, which have previously been obscured on magnetic resonance imaging, could be depicted. Some of the orbital pterygopalatine ganglion branches and the pharyngeal nerve were clearly viewed. Conclusions. In our experience with one human cadaver specimen, magnetic resonance imaging at 7 Tesla seems effective in depicting pterygopalatine fossa anatomy and provides previously unseen details through its demonstration of the pharyngeal nerve and the orbital pterygopalatine ganglion branches. The true viability of depicting the pterygopalatine fossa with ultrahigh-resolution MR will depend on confirmation of our results in larger studies.

A gene expression profile for non-smoking and non-drinking patients with head and neck cancer

OBJECTIVE

A small subset of patients with head and neck squamous cell carcinoma are non-smoking and non-drinking and have distinct clinical characteristics. We aimed to identify a possible different genetic profile for these patients when compared with their smoking and drinking counterparts.

MATERIALS AND METHODS

The gene expression data previously detected from primary tumors located in the oral cavity and oropharynx, using DNA microarray was analyzed for their differential expression between non-smoking and non-drinking patients (n = 15) and smoking and drinking patients (n = 89). Student's T-test (P < 0.05) and 10-fold cross-validation procedure (100 times repeated) were performed to determine differentially expressed genes.

RESULTS

Non-smoking and non-drinking patients were older, mostly female and had oral cavity-localized tumors, whereas smoking and drinking patients were younger male patients with 81% oral cavity and 19% oropharynx tumors. A set of 49 differentially expressed genes were detected. Among others, seven genes related to interferon-γ were upregulated and two genes linked to NFKB pathway were downregulated.

CONCLUSIONS

Differentially expressed genes in non-smoking and non-drinking patients possibly indicate the presence of a different cellular response to carcinogenic events in these patients. Further studies are warranted to validate this gene set and explore possible therapeutic implications to improve prognosis for these patients.

Microvascular decompression of the pterygopalatine ganglion in patients with refractory cluster headache

Background: Cluster headache is an invalidating form of headache. Although cluster headache can be managed pharmacologically, some patients require surgical treatment with varying results. Microvascular decompression of the pterygopalatine ganglion could be an alternative to traditional surgical management in patients with cluster headache.

Methods: Microvascular decompression of the pterygopalatine ganglion was performed in three patients with refractory cluster headache. The pterygopalatine artery was ligated and a temporal muscle graft was placed between the artery and the ganglion.

Results: No differences were found between the presurgical period and 1 week, 1 month, 3 months, and 6 months postoperatively with respect to attack duration and frequency, visual analogue scale score during attacks and in remission periods, duration of remissions, and quality of life.

Conclusion: These preliminary data suggest that microvascular decompression of the pterygopalatine ganglion does not provide pain reduction or improvement of quality of life in patients with refractory cluster headache.

Human Papillomavirus and Oropharyngeal Squamous Cell Carcinoma: A Case-Control Study regarding Tobacco and Alcohol Consumption

We aimed to determine the role of HPV in the pathogenesis and outcome of oropharyngeal squamous cell carcinoma (OSCC) in lifelong nonsmoking and nondrinking patients. A case-case analysis was performed to compare the presence of HPV-DNA in tumor cells of 16 nonsmoking and nondrinking with 16 matched smoking and drinking patients (matching criteria: age at incidence, gender, tumor sublocation, tumor stage). HPV was detected using 2 PCR tests, FISH analysis, and p16^INK4A immunostaining. Nonsmoking and nondrinking patients had more HPV-positive tumors than smoking and drinking patients (n = 12; 75% versus n = 2; 13%; P < 0.001). All HPV-positive tumors showed p16^INK4A overexpression, and 1 HPV-negative tumor had p16^INK4A overexpression, (P < 0.001). Overall survival and disease-specific survival were higher for HPV-positive compared to HPV-negative cases (P = 0.027, P = 0.039, resp.). In conclusion, HPV is strongly associated with OSCC of nonsmoking and nondrinking patients. Specific diagnostic and therapeutic actions should be considered for these patients to achieve a better prognosis.

Sluder's neuralgia: a trigeminal autonomic cephalalgia?

The objective was to formulate distinctive criteria to substantiate our opinion that Sluder's neuralgia and cluster headache are two different clinical entities. A systematic review was carried out of all available, original literature on Sluder's neuralgia. Pain characteristics, periodicity and associated signs and symptoms were studied and listed according to frequency of appearance. Eleven articles on Sluder's neuralgia were evaluated. Several differences between Sluder's neuralgia and cluster headache became evident. Based on described symptoms, new criteria for Sluder's neuralgia could be formulated. Sluder's neuralgia and cluster headache could possibly be regarded as two different headache syndromes, and Sluder's neuralgia could be a trigeminal autonomic cephalalgia.

Quality of life in elderly patients with head and neck cancer one year after diagnosis

BACKGROUND

Little is known about quality of life (QOL) in elderly patients.

METHODS

Seventy-eight older (> or =70 years) and 105 younger patients (45-60 years) with carcinoma of the oral cavity, pharynx (stage > or =II), or larynx (stage > or =III) completed the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire and EORTC Head and Neck Cancer Quality of Life Questionnaire before treatment. Fifty-one older and 70 younger patients completed all follow-up questionnaires at 3, 6, and 12 months.

RESULTS

Before and after treatment, the physical functioning of the older patients was worse than that of younger patients. This difference remained relatively constant during follow-up and is probably related to normal aging. At baseline and 3 months, no other differences were found between both groups. At 6 months, younger patients reported more pain, but at 12 months no relevant differences were found.

CONCLUSIONS

Treatment did not affect QOL differently in older and younger patients. Therefore, standard treatment should always be considered, irrespective of the patient's age.

Local therapy of cancer with free IL-2

This is a position paper about the therapeutic effects of locally applied free IL-2 in the treatment of cancer. Local therapy: IL-2 therapy of cancer was originally introduced as a systemic therapy. This therapy led to about 20% objective responses. Systemic therapy however was very toxic due to the vascular leakage syndrome. Nevertheless, this treatment was a break-through in cancer immunotherapy and stimulated some interesting questions: Supposing that the mechanism of IL-2 treatment is both proliferation and tumoricidal activity of the tumor infiltrating cells, then locally applied IL-2 should result in a much higher local IL-2 concentration than systemic IL-2 application. Consequently a greater beneficial effect could be expected after local IL-2 application (peritumoral = juxtatumoral, intratumoral, intra-arterial, intracavitary, or intratracheal = inhalation). Free IL-2: Many groups have tried to prepare a more effective IL-2 formulation than free IL-2. Examples are slow release systems, insertion of the IL-2 gene into a tumor cell causing prolonged IL-2 release. However, logistically free IL-2 is much easier to apply; hence we concentrated in this review and in most of our experiments on the use of free IL-2. Local therapy with free IL-2 may be effective against transplanted tumors in experimental animals, and against various spontaneous carcinomas, sarcomas, and melanoma in veterinary and human cancer patients. It may induce rejection of very large, metastasized tumor loads, for instance advanced clinical tumors. The effects of even a single IL-2 application may be impressive. Not each tumor or tumor type is sensitive to local IL-2 application. For instance transplanted EL4 lymphoma or TLX9 lymphoma were not sensitive in our hands. Also the extent of sensitivity differs: In Bovine Ocular Squamous Cell Carcinoma (BOSCC) often a complete regression is obtained, whereas with the Bovine Vulval Papilloma and Carcinoma Complex (BVPCC) mainly stable disease is attained. Analysis of the results of local IL-2 therapy in 288 cases of cancer in human patients shows that there were 27% Complete Regressions (CR), 23% Partial Regressions (PR), 18% Stable Disease (SD), and 32% Progressive Disease (PD). In all tumors analyzed, local IL-2 therapy was more effective than systemic IL-2 treatment. Intratumoral IL-2 applications are more effective than peritumoral application or application at a distant site. Tumor regression induced by intratumoral IL-2 application may be a fast process (requiring about a week) in the case of a highly vascular tumor since IL-2 induces vascular leakage/edema and consequently massive tumor necrosis. The latter then stimulates an immune response. In less vascular tumors or less vascular tumor sites, regression may require 9-20 months; this regression is mainly caused by a cytotoxic leukocyte reaction. Hence the disadvantageous vascular leakage syndrome complicating systemic treatment is however advantageous in local treatment, since local edema may initiate tumor necrosis. Thus the therapeutic effect of local IL-2 treatment is not primarily based on tumor immunity, but tumor immunity seems to be useful as a secondary component of the IL-2 induced local processes. If local IL-2 is combined with surgery, radiotherapy or local chemotherapy the therapeutic effect is usually greater than with either therapy alone. Hence local free IL-2 application can be recommended as an addition to standard treatment protocols. Local treatment with free IL-2 is straightforward and can readily be applied even during surgical interventions. Local IL-2 treatment is usually without serious side effects and besides minor complaints it is generally well supported. Only small quantities of IL-2 are required. Hence the therapy is relatively cheap. A single IL-2 application of 4.5 million U IL-2 costs about 70 Euros. Thus combined local treatment may offer an alternative in those circumstances when more expensive forms of treatment are not available, for instance in resource poor countries.

Professional delay in head and neck cancer patients: Analysis of the diagnostic pathway

The aim of this study was to identify which factors are related to specialist delay and to determine the length of the diagnostic pathway in head and neck cancer patients. Three hundred and six patients with a carcinoma of the larynx, pharynx or oral cavity were included in the study. Logistic regression analysis was used to identify risk factors for specialist delay. Large (T3-T4) tumors showed significantly less specialist delay than small (T1-T2) tumors (p=0.045, odds ratio [OR]=0.6). Pharyngeal (p=0.00, OR=0.2) and oral carcinomas (p=0.00, OR=0.2) had less specialist delay than glottic carcinomas. Hoarseness was associated with prolonged specialist delay (p=0.00, OR=5.9). Heavy drinking in combination with smoking (p=0.005, OR=0.3), a sore throat (p=0.02, OR=0.4) or having a lesion (p=0.03, OR=0.2) showed a shorter diagnostic period. The duration of the diagnostic process in a general hospital ranged from 0 to 570 days, with a median of 14 days. Only a small group of patients met the ideal management standards in our head and neck clinic. Although prolonged delay was associated with small (glottic) tumors, the diagnostic process takes a fairly long time. The results indicate that continued educational programs for professionals are warranted.

Do magnetic resonance imaging and ultrasound add anything to the preoperative workup of parotid gland tumors?

PURPOSE

To assess the additional value of magnetic resonance imaging (MRI) and ultrasound (US) to physical examination (PE) and fine needle aspiration cytology (FNAC) in the preoperative determination of the location and histology of parotid gland tumors.

PATIENTS AND METHODS

Prospectively, 99 patients with 77 benign and 22 malignant lesions were included; 82 underwent parotidectomy. FNAC was performed in 88 patients. On PE, the location of the tumor was predicted. Eighty-nine patients had MRI and 47 US. Various characteristics and the presumed diagnosis were assessed. Furthermore, the location of the tumor in relation to the facial nerve was predicted. The results were compared with the definite histology and the location during surgery.

RESULTS

Of the MRI characteristics, incomplete demarcation from normal parotid gland tissue showed the highest positive predictive value (PPV) for malignancy of 0.48. Of the US characteristics, enlarged lymph nodes yielded the highest PPV for malignancy of 0.5. Cytology correctly predicted the benign or malignant nature of the tumor in all cases. Superficial location was well predicted on PE with a PPV of 0.8, slightly better on MRI (PPV of 0.87), and worse on US (PPV of 0.7).

CONCLUSION

FNAC is the only accurate investigation for classifying a parotid gland tumor as benign or malignant. Palpation and MRI are superior to US in predicting tumor location. Because the results for palpation and MRI are almost equal, MRI should only be reserved for specific cases, and not routinely requested.

Non-smoking and non-drinking patients with head and neck squamous cell carcinoma: a distinct population

OBJECTIVE

To recognize specific clinicopathological characteristics of non-smoking and non-drinking (NSND) head and neck squamous cell carcinoma (HNSCC) patients. This can increase our knowledge regarding a potentially different carcinogenesis in these patients.

STUDY DESIGN/METHODS

Retrospective analysis of data for 195 NSND patients with HNSCC and comparison with data for patients with HNSCC obtained from the Netherlands Cancer Registry.

RESULTS

Compared with all HNSCC patients in the Netherlands, our NSND patients with HNSCC were typically female (n = 142; 73%vs 26%), old at disease presentation (mean 73 years vs 64 years), and had tumors mainly of the oral cavity (n = 130; 66%vs 25%). Most tumors were stage I (n = 67; 34%) and stage IVA (n = 59; 30%). The incidence of second primary tumors (SPTs) was high (n = 32; 16%), mainly occurring in the oral cavity (n = 26; 13%).

DISCUSSION/CONCLUSION

Our study confirms that NSND HNSCC patients have different clinicopathological characteristics from those of the overall HNSCC population; however, the frequency of SPTs is as high in NSND patients as in patients who smoke and drink alcohol. More research, and particularly molecular data are needed to obtain a better understanding of head and neck cancer in NSND patients.

The effect of age on survival and quality of life in elderly head and neck cancer patients: a long-term prospective study

Little is known about long-term treatment outcome of elderly head and neck cancer patients and their quality of life (QOL). One hundred and eighteen older (>or=70 years) and 148 younger (45-60 years) patients with head and neck cancer were followed up for 3-6 years. In the long-term follow-up 33 younger and 24 older patients completed the EORTC QLQ-C30 and H&N35 and a questionnaire about depression. The survival rate after 3-6 years for younger patients was 36%, as compared to 31% in the older patient group. Higher tumour stages, more co-morbidity and non-standard treatment showed to be independent prognostic factors for mortality. No independent prognostic value of age could be found. The global QOL score remains roughly comparable. Even up to 6 years after treatment, we found no significant differences in survival or overall QOL between older and younger head and neck cancer patients.

Grading Facial Nerve Function

OBJECTIVE

To compare the interobserver variability of a new grading system to the currently recommended House-Brackmann Grading Scale.

STUDY DESIGN

Prospective case-control study.

SETTING

Tertiary referral center.

PATIENTS

All patients with a facial nerve paresis/paralysis (whatever the cause).

INTERVENTION

All patients were evaluated for their facial nerve function by three observers, independently, using both the new system and the House-Brackmann Grading Scale.

MAIN OUTCOME MEASURE

The level of agreement between the three observers using both scales.

RESULTS

With the movement, rest, secondary defects, and subjective scoring grading scale, a higher percentage of agreement between the observers was noticed than with the House-Brackmann Grading Scale.

CONCLUSION

The movement, rest, secondary defects, and subjective scoring grading system is more useful for grading facial nerve dysfunction in clinical practice than the House-Brackmann Grading Scale.

Morbidity of parotid gland surgery: results 1 year post-operative

Patients operated on for parotid gland tumours were evaluated prospectively to study morbidity after this procedure. Nowadays, major complications such as recurrence of tumour and permanent facial nerve paresis are rare after primary surgery. Therefore, this study especially takes minor complications such as Frey's syndrome and sensory deficits into account. The study documents morbidity in 45 patients who completed a 1 year follow-up. Among those with primary benign tumours, we found no recurrences and no permanent paresis, nor did starch-iodine testing reveal any cases of Frey's syndrome. However, two patients who had previously been operated on multiple times did test positive for Frey's syndrome, as did two others after surgery for malignancy. Furthermore, we found that patients whose posterior branch of the great auricular nerve was sacrificed had a larger area of sensory deficit than those whose nerve was preserved. We conclude that the morbidity of parotid gland surgery can be reduced further by giving minor complications more attention.

Medical care-seeking and health-risk behavior in patients with head and neck cancer: the role of health value, control beliefs and psychological distress

Health behavior plays an important role in the development, detection and course of cancer of the head and neck. Relevant health behavior includes prompt medical care seeking, and smoking and drinking cessation after diagnosis. This study examines the relationship between these health behaviors and health value and control beliefs, as well as psychological distress. Two hundred and sixty-four recently diagnosed head and neck cancer patients were interviewed about their health behavior, and they filled in a questionnaire on health beliefs and psychological distress. The results showed that one-quarter (25%) of the patients had waited more than 3 months before seeking medical care, 50% had continued to smoke and 80% had continued to drink after the diagnosis. The patients, particularly those who smoked and drank before diagnosis, reported lower levels of health value and perceived health competence than a general population sample with which they were compared. Patients who engaged in patient delay reported a lack of perceived health competence. Psychological distress and lack of perceived health competence were found to be more common among patients who continued to smoke. The implications of these findings are discussed with regard to interventions aimed at promoting these specific health behaviors.

Guidelines in head and neck oncology compliance and consequences of deviations from the standard protocol for tongue and floor of mouth squamous carcinoma

OBJECTIVES

To investigate the extent of violation of a regional guideline for the treatment of patients with carcinoma of the tongue/floor of mouth (ICD0 C02, C04). Different aspects of protocol violation (i.e. undertreatment or overtreatment) and consequences for treatment outcome were evaluated.

DESIGN

Retrospective analysis of data from medical records.

SETTING

The Department of Maxillofacial and Oral Surgery and the Department of Otorhinolaryngology and Head and Neck Surgery of the University Medical Centre Utrecht.

PARTICIPANTS

A total of 217 patients treated between 1991 and 2001 for a stage II and stage III carcinoma of the tongue/floor of mouth.

MAIN OUTCOME MEASURES

Protocol violation, tumour recurrence.

RESULTS

The overall adherence to the guideline was 55%. In the non-adherence group of patients, 21% were overtreated, 71% were undertreated, and 8% were both overtreated and undertreated. There was no statistically significant difference in tumour recurrence between the two groups for stage II (P=0.68) or stage III (P=0.97) disease, or between undertreatment and overtreatment of patients with stage II (P=0.47) or stage III (P=0.90) disease.

CONCLUSIONS

Although protocol violation occurs in as many as 45% of patients, this does not result in a worse tumour recurrence. Neither overtreatment nor undertreatment appears to affect the overall tumour recurrence.

Differences in coping style and locus of control between older and younger patients with head and neck cancer

OBJECTIVES

This prospective study analyses whether older and younger patients with cancer of the head and neck make use of different coping styles and locus of control mechanisms, and how these mechanisms are related to quality of life (QOL) and depressive symptoms.

DESIGN

Before treatment, 78 older (>or=70 years) and 105 younger patients (45-60 years) with carcinoma of the oral cavity, pharynx (stage II-IV), or larynx (stage III-IV) completed questionnaires on QOL (EORTC-QLQ-C30), depression (CES-D), coping (Utrecht Coping List), and locus of control (Cancer Locus of Control Scale). Fifty-one older and 70 younger patients completed the follow-up questionnaires at 6 and 12 months.

RESULTS

Before treatment and at 12 months, the number of depressive symptoms and QOL scores, apart from physical functioning, did not differ between the two groups. Before treatment and at 6 months, younger patients used active coping strategies significantly more often and they perceived more internal control over the cause of their disease. Older patients used religious coping and religious control more frequently at all assessments. In both groups, avoidance coping was associated with more depressive symptoms and a worse QOL.

CONCLUSIONS

Although older and younger patients use different coping and locus of control strategies, this does not give rise to differences in QOL and depressive symptoms after treatment.

[Arguments favouring the pharmacotherapy of Bells' palsy]

Some clinicians claim a spontaneous complete recovery of facial nerve function after Bell's palsy in more than 80% of patients. However, for elderly patients and patients with a severe paresis/paralysis this is not the case. The main cause of Bell's palsy is probably reactivation of latent herpes viruses. Recent literature supports treatment with corticosteroids and antiviral medication, inhibiting viral replication and reducing oedema in the bony canal of the facial nerve. Using this medication in the first days of the disease provides a further 15% of patients with a good outcome in addition to the ones that improve spontaneously. Therefore, prednisone and valacyclovir are recommended for all patients with Bell's palsy and severe dysfunction, i.e. House-Brackmann facial grading scale IV, V and VI.

Effectiveness of adenotonsillectomy in children with mild symptoms of throat infections or adenotonsillar hypertrophy: open, randomised controlled trial

OBJECTIVE

To assess the effectiveness of adenotonsillectomy in children with mild symptoms of throat infections or adenotonsillar hypertrophy.

DESIGN

Open, randomised controlled trial.

SETTING

21 general hospitals and three academic centres in the Netherlands.

PARTICIPANTS

300 children aged 2-8 years requiring adenotonsillectomy.

INTERVENTION

Adenotonsillectomy compared with watchful waiting.

MAIN OUTCOME MEASURES

Episodes of fever, throat infections, upper respiratory tract infections, and health related quality of life.

RESULTS

During the median follow up period of 22 months, children in the adenotonsillectomy group had 2.97 episodes of fever per person year compared with 3.18 in the watchful waiting group (difference -0.21%, 95% confidence interval -0.54 to 0.12), 0.56 throat infections per year compared with 0.77 (-0.21, -0.36 to -0.06), and 5.47 upper respiratory tract infections per person year compared with 6.00 (-0.53, -0.97 to -0.08). No clinically relevant differences were found for health related quality of life. Adenotonsillectomy was more effective in children with a history of three to six throat infections than in those with none or two. 12 children had surgery related complications.

CONCLUSION

Adenotonsillectomy in children with mild symptoms of throat infections or adenotonsillar hypertrophy has no major clinical benefits over watchful waiting.

Elderly patients with head and neck cancer: the influence of comorbidity on choice of therapy, complication rate, and survival

PURPOSE OF REVIEW

Comorbidity may be an important reason for head and neck surgeons to treat elderly patients less intensively. This article provides an overview of the influence of age and comorbidity on choice of therapy, postoperative complications, and survival.

RECENT FINDINGS

Several retrospective studies show that elderly patients can undergo surgery if they do not have severe comorbid disorders. Severe comorbidity influences the rate of postoperative complications, and the higher complication rate in older patients reported in some studies is probably due to a higher level of comorbidity. Comorbidity also affects the survival of cancer patients, but several studies have failed to detect a relation between age and survival after correction for comorbidity. Thus, although severe comorbidity may influence the choice of treatment, patient age as such should not be a reason to exclude patients from intensive therapy.

SUMMARY

If severe comorbidity is not present, elderly patients should receive standard treatment for head and neck cancer. Treatment choice should be based on medical findings and patient preference, not on chronologic age.

Warthin's tumour and smoking

OBJECTIVE

In an evaluation of our patients with parotid gland neoplasms, we noticed that patients with a Warthin's tumour were heavy smokers. The aim of this study was to confirm earlier findings in the literature concerning a possible association between smoking and the development of a Warthin's tumour.

METHODS

A case control study was performed using the clinical records and discharge letters of all consecutive patients with a Warthin's tumour in the pathology database of our hospital covering the last 15 years. Patients with a pleomorphic adenoma and a group of patients visiting our audiology department were used as controls.

RESULTS

A smoking history was found in 97.5% of the patients with a Warthin's tumour. Of the patients with a pleomorphic adenoma, 59% had a smoking history; 56.5% of the audiology group had a smoking history. Mean age at the time of the operation was 60.1 years of age in the Warthin's tumour group and 48.6 for the pleomorphic adenoma group.

CONCLUSION

The mean age for the development of a Warthin's tumour is ten years older than for a pleomorphic adenoma. Furthermore, the development seems to be closely related to smoking habits.

Simultaneous radio- and chemotherapy for squamous cell carcinoma of the head and neck in daily clinical practice: 5 years experience in a University Hospital

Several randomized studies and meta-analyses have shown that simultaneous radio- and chemotherapy prolongs survival in patients with unresectable squamous cell carcinoma of the head and neck as compared with conventional radiotherapy. We assessed the feasibility and effectiveness of simultaneous radiotherapy (35 x 2 Gy) and chemotherapy [cisplatinum 100 mg/m(2) or carboplatin (AUC 6) on days 1, 22 and 43] in daily clinical practice in a cohort of 87 patients treated at our institute between 1998 and 2002. Eighty patients completed radiotherapy according to schedule. Eighty patients received two courses of chemotherapy and 50 patients three courses. Nephrotoxity, bone marrow suppression and ototoxicity were the most frequent side-effects. Median weight loss was 8.5%. Median survival was 15 months and 44% of the patients were alive at 2 years. Patients receiving three courses of chemotherapy had a better survival than patients receiving two or less courses. Treatment with simultaneous radio- and chemotherapy for advanced head and neck cancer is a demanding, but feasible treatment in daily clinical practice. Survival seems to be comparable with the results achieved in patients selected for clinical trials.

Effectiveness of adenotonsillectomy in children with mild symptoms of throat infections or adenotonsillar hypertrophy: open, randomised controlled trial

OBJECTIVE

To assess the effectiveness of adenotonsillectomy in children with mild symptoms of throat infections or adenotonsillar hypertrophy.

DESIGN

Open, randomised controlled trial.

SETTING

21 general hospitals and three academic centres in the Netherlands.

PARTICIPANTS

300 children aged 2-8 years requiring adenotonsillectomy.

INTERVENTION

Adenotonsillectomy compared with watchful waiting.

MAIN OUTCOME MEASURES

Episodes of fever, throat infections, upper respiratory tract infections, and health related quality of life.

RESULTS

During the median follow up period of 22 months, children in the adenotonsillectomy group had 2.97 episodes of fever per person year compared with 3.18 in the watchful waiting group (difference -0.21, 95% confidence interval -0.54 to 0.12), 0.56 throat infections per person year compared with 0.77 (-0.21, -0.36 to -0.06), and 5.47 upper respiratory tract infections per person year compared with 6.00 (-0.53, -0.97 to -0.08). No clinically relevant differences were found for health related quality of life. Adenotonsillectomy was more effective in children with a history of three to six throat infections than in those with none to two. 12 children had complications related to surgery.

CONCLUSION

Adenotonsillectomy has no major clinical benefits over watchful waiting in children with mild symptoms of throat infections or adenotonsillar hypertrophy.

Psychological factors and patient delay in patients with head and neck cancer

There is a rising incidence of patients presenting with advanced cancer in the head and neck region. Late presentation may be due to a delay in seeking medical attention, which is sometimes surprisingly long. The aim of the present prospective study was to investigate the association between patient delay and the psychological factors of optimism, health hardiness, overall defensive functioning, coping styles and psychological distress in 277 patients with cancer of the head and neck. Significant correlations were found between patient delay and the psychological factors. Twenty-six percent of the patients waited more than three months before seeking medical attention and they reported less optimism (P = 0.0001), less health hardiness (P = 0.008), less active coping (P = 0.019) and less seeking support as a coping style (P = 0.017) than patients presenting within three months. Excessive drinkers (5+ alcoholic drinks/day) tended to show more delay than patients who did not drink or were moderate drinkers (0-2 drinks/day) or moderate-heavy drinkers (3-4 drinks/day). Together, the psychological factors could explain 25% of the variance of patient delay in excessive drinkers compared with 21% and 6% in moderate-heavy drinkers and non-drinkers to moderate drinkers, respectively. These results suggest that psychological factors affect health-care seeking behaviour. Health education aimed at the risk group of excessive drinkers should take psychological factors into account that influence their health behaviour.

Elderly patients with head and neck cancer: physical, social and psychological aspects after 1 year

OBJECTIVE

Elderly patients with head and neck cancer often receive non-standard treatment for reasons other than comorbidity. In this prospective study we investigated how elderly patients fare 1 year after treatment in comparison with their younger counterparts.

MATERIAL AND METHODS

Seventy patients aged 45-60 years and 51 patients aged > or = 70 years with cancer of the oral cavity, pharynx (stage II-IV) or larynx (stage III-IV) participated in the study before treatment and 1 year later. Each patient was interviewed and given a questionnaire concerning physical functioning, social contacts, depressive symptoms, satisfaction with treatment and future expectations.

RESULTS

At 12 months, patients in both age groups reported significantly more depressive symptoms and less social support than before treatment, and their Karnofsky Performance Score was lower. However, there were no differences between elderly and younger patients. Approximately 90% of those in both age groups said that they would choose the same treatment again, and there was no age difference regarding the impact of treatment or expectations for the future.

CONCLUSION

This study shows that the impact of treatment on quality of life did not differ between elderly and younger patients with head and neck cancer. Therefore, standard treatment should be considered in elderly patients if no severe contraindications exist.

Reasons for non-standard treatment in elderly patients with advanced head and neck cancer

Elderly patients with head and neck cancer are less likely to receive standard treatment. This study assessed the influence that age, tumour characteristics, comorbidity, social support, depressive symptoms and quality of life have on treatment choice. One hundred and five patients between 45 and 60 years of age and 78 patients of > or =70 years of age with carcinoma of the oral cavity (stage > or =II), oro- and hypopharynx (stage > or =II) or larynx (stage > or =III) completed a questionnaire on quality of life (EORTC QLQ-C30 and H&N35), depressive symptoms (CES-D) and social support (RSS12-I). In the 45-60 age group, 89% received standard treatment, compared with 62% of the > or =70 age group. A multivariate logistic regression analysis showed that the following factors predicted non-standard treatment: marital status (widowed), advanced tumour stage, comorbidity, less pain, considering the length of life less important than its quality and old age. This study showed that age itself independently influences treatment choice. However, it should be emphasised that the choice of a treatment should be based on a medical assessment and the patient's preferences, not on chronological age.

Elderly patients with head and neck cancer: short-term effects of surgical treatment on quality of life

Elderly patients with head and neck cancer are less likely to be treated surgically. However, little is known about surgical outcome and quality of life (QOL) in elderly patients after a major surgery. This prospective study compared the QOL and the surgical outcome of 54 elderly (> or =70 years) and 75 younger patients (45-60 years) with carcinoma of the oral cavity (stage > or = II), pharynx (stage > or = II) or larynx (stage > or = III). Before and 3 months after surgery, the patients completed questionnaires about QOL (EORTC QLQ-C30 and QLQ-H&N35) and depression (CES-D). Before treatment, elderly and younger patients did not differ in QOL. Three months after the treatment, both groups scored worse on most QOL aspects, but there were no significant differences between the elderly and the younger patients. Surgical and systemic complication rates were similar for both the groups. In conclusion, we found no significant differences in the complication rate and QOL aspects between surgically treated elderly and younger patients.

[Tumor growth during the waiting period for radiotherapy in patients with oropharyngeal carcinoma]

OBJECTIVE

To quantify the potential increase in tumour volume during the waiting time for radiotherapy in patients with oropharyngeal squamous cell carcinoma.

DESIGN

Retrospective study.

METHOD

The tumour volumes as assessed on the diagnostic CT scan and the planning CT scan were compared. Thirteen patients with oropharyngeal carcinoma were included in this study. Both their diagnostic CT scan (CT-1) and their planning CT scan (CT-2) were performed in the Utrecht university medical centre. Tumour volume was calculated by delineating the tumour on CT slices and multiplying the surface area by the inter-slice distance. Tumour volumes were delineated by three independent observers. Tumour growth during the waiting time was defined as the difference in tumour volume on CT-2 and CT-1, calculated as the average of three observations.

RESULTS

The mean time between CT-1 and CT-2 was 33 days. The mean waiting period between the histopathological diagnosis and the start of radiotherapy was 56 days. Three groups could be distinguished: in one group the growth was less than 25% (n = 4), in one group the growth varied between 25 and 100% (n = 5), and in a third group there was growth of more than 100% (n = 4). Apart from this, in three cases the TNM stage had to be adjusted as a result of tumour progression.

CONCLUSION

This study showed that the tumour volume increased by more than 50% during the waiting time for radiotherapy in 8 out of 13 patients with squamous cell carcinoma of the oropharynx.

Increasing incidence of advanced stage head and neck tumours

The aim of this study was to determine whether the incidence of advanced stage (T4) head and neck tumours has increased. We analysed retrospectively 3178 patients diagnosed with oral, pharyngeal or laryngeal cancer in the period 1980-2000 at the University Medical Center Utrecht (UMCU), The Netherlands. There was a statistically significant increase in the proportion of T4 head and neck tumours compared with non-T4 tumours over the period 1980-2000. Linear regression analysis estimated an increase of 0.9% every year. The observed increase in T4 tumours at UMCU shows up in figures from the Netherlands Regional Cancer Registry (IKMN) and the National Cancer Registration (NCR). Although these bodies report for fewer years, this finding refutes the possibility of selected referral to the University Medical Center Utrecht. In conclusion, the number of head and neck cancer patients presenting with an advanced stage carcinoma (T4) has increased over a period of 21 years.

Current indications for (adeno)tonsillectomy in children: a survey in The Netherlands

OBJECTIVE

Despite the fact that (adeno)tonsillectomy is one of the procedures most frequently performed on children, studies of current indications are scarce. The purpose of this study is to determine the indications for (adeno)tonsillectomy in children younger than 15 years of age according to Dutch ENT surgeons and general practitioners (GPs).

METHODS

During a period of 8 months, 18 ENT surgeons in seven ENT practices and 210 referring GPs filled out standard questionnaires for 349 children listed for tonsil surgery.

RESULTS

Apart from recurrent tonsillitis (ENT: 40%, GP: 35%), findings such as enlarged tonsils (ENT: 42%, GP: 24%) and tonsillar crypt debris (ENT: 29%, GP: 17%) and non-specific symptoms such as listlessness (ENT: 28%, GP: 19%) and poor appetite (ENT: 28%, GP: 16%) were considered important criteria for surgery. Symptoms of obstructive sleep apnea were present in 25% (ENT) and 6% (GP) of patients but were considered indicative for surgery in only 11% (ENT) and 4% (GP). In contrast to ENT surgeons, GPs considered otitis media and hearing loss relatively important for (adeno)tonsillectomy.

CONCLUSIONS

Apart from the generally accepted indications such as recurrent tonsillitis and obstructive sleep apnea, other indications play an equally important role in the decision to perform tonsil surgery in The Netherlands.

[Rising incidence of invasive (T4) head-neck carcinoma at the Utrecht University Medical Center, 1980-1998]

OBJECTIVE

To determine whether there is an increase in the incidence of diagnosed head and neck tumours at an advanced stage (T4).

DESIGN

Secondary data-analysis.

METHOD

Data of patients registered in 1980-1998 at the Utrecht University Medical Centre, the Netherlands, were analysed for the relative prevalence of T4 tumours in the oral cavity, pharynx and larynx on the basis of sex, age and tobacco and alcohol usage. The results were compared with figures from the Dutch national cancer registry (1989-1997).

RESULTS

Data were collected for 2993 patents (2256 men and 737 women; average age 63 years (SD 12)). Of these 35 had a carcinoma situated on the lips, 1091 in the oral cavity, 1321 in the larynx and 546 in the pharynx. There was an increase in T4 tumours of 12.2% (43/353) of all tumours in 1980-1984 to 27.2% (252/1033) in 1995-1998. Linear regression analysis estimated an increase of 0.9% every year. Selected referral to the Utrecht University Medical Centre was unlikely because the increased incidence of T4 tumours could be recognised in the national cancer registry. There was no change in the sex distribution over the study period. The increase in the 40 to 50-year-old age group was greater than that of the patients aged 80 years and over. T4 tumours were more prevalent than T1 tumours in patients who had smoked 20 or more cigarettes per day or drank more than 4 units of alcohol per day.

CONCLUSION

The percentage of cancer patients presenting with an advanced stage (T4) of head-neck tumours increased during the study period.

Carcinoma of the larynx: the Dutch national guideline for diagnostics, treatment, supportive care and rehabilitation

PURPOSE

This evidence based guideline aims to facilitate proper management and to prevent diverging views concerning diagnosis, treatment and follow-up of carcinoma of the larynx between the major referral centers for head and neck cancer in The Netherlands.

METHOD

A multidisciplinary committee was formed representing all medical and paramedical disciplines involved in the management of laryngeal cancer and all head and neck oncology centers in The Netherlands. This committee reviewed the literature and formulated statements and recommendations based on the level of evidence and consistency of the literature data. Where reliable literature data were not available, recommendations were based on expert opinion.

RESULTS

Strict criteria have been proposed for the radiological diagnostic procedures as well as for the pathology report. For carcinoma in situ and severe dysplasia, microsurgery, preferably by laser, is proposed. For all other stages of invasive carcinoma, a full course of radiotherapy as a voice conserving therapy is the treatment of choice. Only in cases with massive tumor volumes with invasion through the laryngeal skeleton, primary surgery is inevitable. For rehabilitation and supportive care, minimal criteria are described. Due to the complexity of therapy and relative rarity of larynx carcinoma, all patients should be seen at least once in a dedicated head and neck clinic.

CONCLUSION

This guideline for the management of larynx carcinoma was produced by a multidisciplinary national committee and based on scientific evidence wherever possible. This procedure of guideline development has created the optimal conditions for nationwide acceptance and implementation of the guideline.

P53 tumor suppressor gene mutations in laryngeal cancer and in recurrent disease following radiation therapy

In this study we performed p53 sequencing based mutation analysis in laryngeal cancers and matched recurrent disease following irradiation. The question is if irradiation affects the DNA and introduces or deletes mutations so that p53 cannot be used as a clonal marker anymore. P53 mutations were identified in fresh-frozen laryngectomy specimens with either primary laryngeal cancers, treated by surgery and irradiation post-operative with local failure during follow-up, or with recurrent laryngeal cancers following primary irradiation. In 21 tumors the p53 status was analyzed by direct sequencing full-length mRNA through RT-PCR. DNA sequencing analysis of exons 2 through 11 was performed when RNA isolation could not be performed. The marker mutation identified in this way was detected by DNA sequencing of the corresponding exon in formalin-fixed deparaffinized tumor biopsy samples in respectively matched recurrent disease following surgery and irradiation or primary tumor before irradiation. DNA sequencing analysis of the corresponding exon of peripheral blood leukocytes excluded the presence of germline mutations or polymorphisms. In 16 out of 21 tumors (71%), a mutation was identified. Fifteen of these marker mutations were detected in the matched tumor biopsy sample (94%). The only case lacking the marker mutation probably was a second primary tumor. We conclude that we find no direct evidence for induction or loss of p53 mutations following irradiation. Consequently, p53 may be used as a diagnostic tool when histological examination fails, for example in discriminating between the presence of a second primary tumor in the same area versus recurrent disease.

Quantitative dose-volume response analysis of changes in parotid gland function after radiotherapy in the head-and-neck region

PURPOSE

To study the radiation tolerance of the parotid glands as a function of dose and volume irradiated.

METHODS AND MATERIALS

One hundred eight patients treated with primary or postoperative radiotherapy for various malignancies in the head-and-neck region were prospectively evaluated. Stimulated parotid flow rate was measured before radiotherapy and 6 weeks, 6 months, and 1 year after radiotherapy. Parotid gland dose-volume histograms were derived from CT-based treatment planning. The normal tissue complication probability model proposed by Lyman was fit to the data. A complication was defined as stimulated parotid flow rate <25% of the preradiotherapy flow rate.

RESULTS

The mean stimulated preradiotherapy flow rate of 174 parotid glands was 0.34 mL/min. The mean flow rate reduced to 0.12 mL/min 6 weeks postradiotherapy, but recovered to a mean flow rate of 0.20 mL/min at 1 year after radiotherapy. Reduction in postradiotherapy flow rate correlated significantly with mean parotid dose. No threshold dose was found. Increasing the irradiated volume of parotid glands from 0%-40% to 90-100% in patients with a mean parotid dose of 35-45 Gy resulted in a decrease in flow ratio from, respectively, approximately 100% to less than 10% 6 weeks after radiation. The flow ratio of the 90%-100% group partially recovered to 15% at 6 months and to 30% at 1 year after radiotherapy. The normal tissue complication probability model parameter TD(50) (the dose to the whole organ leading to a complication probability of 50%) was found to be 31, 35, and 39 Gy at 6 weeks, 6 months, and 1 year postradiotherapy, respectively. The volume dependency parameter n was around 1, which means that the mean parotid dose correlates best with the observed complications. There was no steep dose-response curve (m = 0.45 at 1 year postradiotherapy).

CONCLUSIONS

This study on dose/volume/parotid gland function relationships revealed a linear correlation between postradiotherapy flow ratio and parotid gland dose and a strong volume dependency. No threshold dose was found. Recovery of parotid gland function was shown at 6 months and 1 year after radiotherapy. In radiation planning, attempts should be made to achieve a mean parotid gland dose at least below 39 Gy (leading to a complication probability of 50%).

F-18-fluoro-deoxy-glucose positron-emission tomography scanning in detection of local recurrence after radiotherapy for laryngeal/ pharyngeal cancer

BACKGROUND

The objective of this investigation was to determine whether F18-fluoro-deoxy-glucose (FDG) positron-emission tomography (PET) could differentiate between local recurrence and late radiation effects after radiotherapy for laryngeal/pharyngeal cancer.

METHODS

In a prospective study of 75 patients (67 larynx, eight oro/hypopharynx), 160 laryngoscopies and 109 FDG PET scans were performed on the head and neck region. The mean follow-up time after the first FDG PET scan was 23 months (minimum 1 year).

RESULTS

Local recurrence was diagnosed in 37 patients: 19 after the first biopsy and 18 after follow-up biopsies. For all of the negative initial FDG scans (27), the biopsies that were taken at the same time were negative and no recurrence was seen for at least 1 year. The first FDG scan was a true positive in 34 of 48 patients. In 12 of the 14 patients with false-positive results, FDG scans were repeated; a decreased FDG uptake was found in 9 of the 12. The sensitivity and specificity of the first scan were respectively 92% and 63%; including subsequent FDG scans, the rates were 97% and 82%, respectively.

CONCLUSIONS

When a local recurrence is suspected after radiotherapy for cancer of the larynx/pharynx, an FDG PET scan should be the first diagnostic step. No biopsy is needed if the scan is negative. If the scan is positive and the biopsy negative, a decreased FDG uptake measured in a follow-up scan indicates that a local recurrence is unlikely.

Prediction of depression 6 months to 3 years after treatment of head and neck cancer

BACKGROUND

Head and neck cancer and its treatment can have important psychosocial implications. Many patients become depressed. The aim of this prospective study is to examine whether pretreatment variables can be used to predict depression up to 3 years after treatment.

METHODS

Head and neck cancer patients (n = 197) treated with surgery and/or radiotherapy completed both before and after treatment a questionnaire including items on social support, coping, depressive symptoms, physical functioning, and physical symptoms.

RESULTS

Eight pretreatment variables (tumor stage, sex, depressive symptoms, openness to discuss cancer in the family, available appraisal support, received emotional support, tumor-related symptoms, and size of the informal social network) were used to calculate a risk score to determine which patients were depressed at 6 months to 3 years after treatment (positive predicted value, 58%; negative predicted value, 83%).

CONCLUSIONS

Eight pretreatment variables can be used to predict accurately those head and neck cancer patients who are likely to become depressed up to 3 years after treatment.

[CBO guideline 'larynx carcinoma']

The guideline 'Larynx carcinoma' aims at preventing divergent views on the treatment of different stages of larynx carcinoma between the major referral centres. Strict criteria are proposed for the radiological diagnostic procedures and the pathology report in order to accurately classify the patient in the appropriate prognostic category. Taking into consideration possible subsequent treatments, surgery--preferably by laser--is proposed for severe dysplasia and carcinoma in situ. For all other stages the treatment of choice is radiotherapy as a larynx conserving therapy. Only in cases of massive tumour volumes with invasion through the laryngeal skeleton where the chance of cure is low with radiotherapy, surgery is the treatment of choice. Minimal criteria are described for rehabilitation and supportive care. Due to the relative rarity of the disease and the complexity of the treatment, all patients with a laryngeal carcinoma should be seen at least once in a dedicated head and neck clinic.

Preoperative determination of the location of parotid gland tumors by analysis of the position of the facial nerve

PURPOSE

This study examined the usefulness of anatomic lines in predicting the intraparotid course of the facial nerve.

MATERIALS AND METHODS

To make the comparison, 3 lines were drawn on 69 transverse sections of 5 cadaver heads. Then, the shortest and the longest distance from the lines to the facial nerve were measured.

RESULTS

Of the tested lines, the one that connects the most dorsal point on the ipsilateral half of a vertebra to the dorsal side of the retromandibular vein had the shortest distance to the facial nerve. It also ran more parallel to the facial nerve than the other 2 lines.

CONCLUSIONS

Because the line that connects the most dorsal point on the ipsilateral half of a vertebra to the dorsal side of the retromandibular vein best predicts the intraparotid course of the facial nerve, it might be useful in assessing whether parotid tumors are located in the superficial or deep lobe.

Landmarks for parotid gland surgery

Many surgical landmarks have been suggested to help the surgeon identify the facial nerve when performing parotid gland surgery. There is no conclusive evidence that any one landmark is better than the rest. In this study distances from the most frequently used surgical landmarks to the main trunk of the facial nerve were measured in 30 halves of cadaver heads. Two ENT surgeons assessed the best landmark in each case. The tympanomastoid suture was nearest to the main trunk and was therefore considered the most reliable landmark. Its average distance to the main trunk of the facial nerve was 2.7 mm. This result was consistent with the subjective best score given by two ENT surgeons.

Sociodemographic factors and quality of life as prognostic indicators in head and neck cancer

Pre-treatment quality of life (QOL) has been found to be an independent prognostic factor for survival in cancer patients, in particular in patients with advanced cancer. Sociodemographic factors such as marital and socioeconomic status have also been recognised as prognostic factors. We studied the influence of QOL and mood (measured with the European Organization for Research and Treatment of Cancer Core Questionnaire (EORTC QLQ-C30) and the Head and Neck Cancer Questionnaire (EORTC QLQ-H&N35), and with the Center for Epidemiologic Studies-Depression Scale (CES-D)) as measured before treatment, the use of cigarettes and alcohol and sociodemographic factors (age, gender, marital status, income and occupation) on recurrence and survival in 208 patients with head and neck cancer prior to treatment with surgery and/or radiotherapy, using Kaplan-Meier and Cox regression analyses. Cognitive functioning and, to a lesser degree, marital status were independent predictors of recurrence and survival, along with medical factors (stage and radicality). Patients with less than optimal cognitive functioning and unmarried patients had a relative risk (RR) of recurrence of 1.72 (95% confidence interval (95% CI) 1.01-2.93) and 1.85 (95% CI 1.06-3.33), respectively, and a RR of dying of 1.90 (95% CI 1.10-3.26) and 1.82 (95% CI 1.03-3.23), respectively. Performance status, physical functioning, mood and global QOL and smoking and drinking did not predict for recurrence and survival. The influence of cognitive functioning might be related to the use of alcohol. Marital status may influence prognosis through mechanisms of health behaviour and/or social support mechanisms.

Proliferative capacity in head and neck cancer

BACKGROUND

Shortening of overall treatment time (accelerated radiotherapy) appears to result in an increase of the efficacy of irradiation. In this study, we compared the proliferative capacity between tumors originating in different sites of the head and neck region. Tumors with a large proliferating capacity might, theoretically, benefit most from accelerated radiotherapy.

MATERIAL AND METHODS

BrdUrd was administered intravenously in patients with head and neck carcinomas. Tumor samples were analyzed with flow cytometry. T and N stages were assessed in accordance with the TNM classification system (UICC 1987).

RESULTS

No significant differences in proliferation parameters were observed with respect to site of origin of head and neck tumors. For T3/T4 tumors, DNA ploidy is an important tumor characteristic: G1- and S-phase fractions, labeling index, and tumor doubling time Tpot differences were statistically significant; the aneuploid tumors showed the largest proliferative potential.

CONCLUSIONS

(1) In general, no significant differences in proliferation parameters were observed with respect to site of origin. (2) Aneuploid head and neck tumors have a higher proliferative capacity than diploid ones, they might benefit most from accelerated irradiation.

Prediction of depressive symptomatology after treatment of head and neck cancer: the influence of pre-treatment physical and depressive symptoms, coping, and social support

BACKGROUND

Head and neck cancer and its treatment can have important psychosocial implications, and many patients become depressed. The aim of this prospective study is to examine whether pretreatment variables can be used to predict depression 6 and 12 months later.

METHODS

Head and neck cancer patients (155) treated with surgery and/or radiotherapy completed a questionnaire including items on social support, coping, depressive symptoms, physical functioning, and physical symptoms before and after treatment.

RESULTS

By using 5 variables (physical symptoms, depressive symptoms, emotional support, extent of the social network, and avoidance coping), it was possible to predict those patients who would have symptoms at 6 (81%) and 12 months (67%) after treatment. Inclusion of actual physical symptoms reported at follow-up increased these percentages to 89% and 82%.

CONCLUSIONS

It is concluded that screening for psychosocial variables and physical symptoms before treatment can be used to determine which patients are at risk of developing depressive symptoms after treatment.

Fluorodeoxyglucose positron emission tomography, a new technique for increasing the detection rate of coincident thyroid cancer in head and neck oncology

Clinically occult thyroid cancer is not uncommon and may occur in 1% to 10% of the population Since the first studies on the use of fluorodeoxyglucose positron emission tomography (FDG PET) in clinical oncology some reports have appeared on the detection of occult tumors using this imaging modality. According to these results, the number of patients with head and neck cancer and clinically occult coincident primary tumors at initial presentation may be expected to increase. In two of the four patients presented, the coincident tumor was detected with FDG PET. The possible role of this new imaging technique is discussed in correlation with treatment and clinical outcome.

Pretreatment factors predicting quality of life after treatment for head and neck cancer

BACKGROUND

Quality of life (QOL) has become an important issue in head and neck cancer. Explanation of factors predicting QOL after treatment has important implications for patient management.

METHODS

In this prospective study we analyzed which pretreatment factors predicted QOL after surgery and/or radiotherapy with curative intent in a cohort of 153 patients with cancer of the oral cavity, oropharynx, hypopharynx, or larynx. The patients completed the EORTC Core Questionnaire, the EORTC Head and Neck Cancer module, and the Center for Epidemiologic Studies Depression scale before treatment and 6 and 12 months later. The influence of gender, age, performance status, and depressive symptoms at baseline, site, stage, and treatment on QOL (and its dimensions) and depressive symptoms after 6 and 12 months was studied, using linear regression analysis.

RESULTS

A high level of depressive symptoms and a low performance status at baseline and combination treatment were significant predictors of increased severity of symptoms and poor functioning after treatment. Treatment was a predictor of head and neck symptoms, whereas performance status and depressive symptoms were predictors of general symptoms and functioning. Gender and age had little predictive value.

CONCLUSIONS

Patients with depressive symptoms or a low performance status who receive combination treatment for cancer of the head and neck are at risk for physical and psychologic morbidity after treatment. Special attention should be given to these patients in rehabilitation programs.

Does waiting time for radiotherapy affect local control of T1N0M0 glottic laryngeal carcinoma?

This is a retrospective study of 362 patients with a T1N0M0 glottic laryngeal carcinoma treated by radiotherapy. Waiting time was defined as time from the day of histopathological diagnosis to the first day of radiotherapy. The Cox regression model was used to analyse the influence of waiting time for radiotherapy on the incidence of recurrence. The median follow-up time was 4.4 years. The median waiting time for radiotherapy was 43 days. Local recurrences were found in 58 patients. There was no significant correlation (P= 0.88) between waiting time and the outcome of early glottic cancer as analysed by Cox regression. This retrospective study did not demonstrate an effect of waiting time for radiotherapy on the outcome of early glottic laryngeal cancer.

Preoperative evaluation of patients with primary head and neck cancer using dual-head 18fluorodeoxyglucose positron emission tomography

OBJECTIVE

To evaluate the value of 18fluorodeoxyglucose (FDG) positron emission tomography (PET) in primary head and neck cancer.

BACKGROUND DATA

Head and neck carcinomas tend to metastasize to regional lymph nodes rather than to spread hematogenously. With nodal metastases, cure rates decrease by approximately 50%. Moreover, in approximately 3% of the patients, a second primary tumor is found at initial presentation.

METHODS

Fifty-four consecutive patients (31 men and 23 women; mean age 60 years, range 34-81 years) with previously untreated squamous cell carcinomas of the oral cavity or oropharynx were studied. Before surgery and within a period of 3 weeks, clinical examination, chest x-ray, computed tomography (CT), ultrasonography with fine-needle aspiration cytology (US/ FNAC), and FDG-PET were performed. All study results were scored per neck side and were also classified as 0 (no metastases), 1 (single metastasis), or 2 (multiple metastases).

RESULTS

The sensitivity for the detection of lymph node metastases per neck side was 96%, 85%, and 64% for FDG-PET, CT, and US/FNAC, respectively. The specificity was 90%, 86%, and 100% for FDG-PET, CT, and US/FNAC, respectively. In terms of the classification, FDG-PET showed the best correlation with the histologic data. Finally, in nine patients (17%), a second primary tumor was detected by FDG-PET and confirmed by histologic evaluation.

CONCLUSION

Because of the high prevalence of second primary tumors detected by FDG-PET and the decreased error rate in the assessment of lymph node involvement compared with CT and US, FDG-PET should be routinely performed in patients with primary head and neck cancer.

Negative and positive influences of social support on depression in patients with head and neck cancer: a prospective study

Patients with head and neck cancer have to cope not only with a life threatening diagnosis, but also with an altered facial appearance and the loss or impairment of important functions as a result of treatment. As a consequence they are prone to psychosocial problems. Social support might influence their ability to adapt to the illness and its treatment. The aim of this prospective study is to examine the influence of different aspects of social support on the depressive symptomatology in head and neck cancer patients treated with surgery and/or radiotherapy. Patients completed a questionnaire relating to available and received support, the extent of the social network, depressive symptoms, and general health complaints before and 6 months after treatment. Received support was found to be associated with more depressive symptomatology at baseline and available support led to less depressive symptomatology. The relationship between social support and depressive symptoms was especially apparent in patients with few general health complaints. Whereas the availability of support seemed to be beneficial regardless of the situation, the effect of received support was equivocal. The provision of support should be tailored to the needs of the individual patient.

Long-term quality of life of patients with head and neck cancer

OBJECTIVES

To describe prospectively the long-term changes of quality of life and mood in patients with squamous cell carcinoma of the head and neck treated with surgery and/or radiotherapy.

PATIENTS AND METHODS

One hundred seven patients completed the European Organization for Research and Treatment of Cancer (EORTC) Core Questionnaire, the EORTC Head and Neck Cancer Module, and the Center for Epidemiological Studies Depression Scale before treatment, and 6, 12, 24, and 36 months later.

RESULTS

There was limited deterioration of physical and role functioning and of many head and neck symptoms at 6 months, with improvement thereafter. After 36 months only physical functioning, taste/ smell, dry mouth, and sticky saliva were significantly worse, compared with baseline. Female sex, higher cancer stage, and combination treatment were associated with more symptoms and worse functioning. Despite physical deterioration, there was a gradual improvement of depressive symptomatology and global quality of life.

CONCLUSION

Treatment for head and neck cancer results in short-term morbidity, most of which resolves within 1 year. Despite an initially high level of depressive symptomatology, there is gradual improvement of psychological functioning and global quality of life over the course of 3 years. In this prospective study, the impact of the disease and its treatment in long-term survivors seems to be less severe than it is often assumed to be.
