Cost and morbidity of MRSA in head and neck cancer patients: what are the consequences?

Methicillin resistant Staphylococcus aureus (MRSA) has become a prevalent nosocomial pathogen worldwide. The objectives of this study were to assess the morbidity and cost associated with the treatment of head and neck cancer patients who become colonized or infected with MRSA following major surgical procedures. We present a retrospective review of patients who underwent major surgery for head and neck cancer over a one year period and who then became MRSA positive in the post-operative period. MRSA affected 25/55 (45 per cent) patients who underwent major head and neck procedures during the period studied. The mean time of diagnosis was 13 days post-surgery. Morbidity included cellulitis, osteomyelitis and MRSA pneumonia. Thirteen of the patients who became MRSA positive (52 per cent of the MRSA group) required further surgery including plate removal, new flap formation and wound debridement as a result of the infection. Average in-hospital stay was almost three times more prolonged for patients who became MRSA positive compared to those who did not have MRSA. The costs of the first hospital stay were over three times more in the MRSA-positive group of patients. Antibiotic costs were increased by pound 2470 per patient because of MRSA. The extra stay in hospital, together with extra days in intensive care, extra medical and nursing care and additional costly antibiotic treatment, led to major cost implications and loss of health service resources in the unit. MRSA infection is a serious cause of morbidity in any surgical group of patients and this study focuses on the consequences for treatment of head and neck cancer patients in particular.     

Erythropoietin in patients with head and neck carcinomas?

BACKGROUND: Various studies have demonstrated the prognostic significance of the pretherapeutic blood hemoglobin concentration for patients with head and neck cancer following surgery or primary definitive or adjuvant radio- or radiochemotherapy. It was the aim of this study to evaluate whether the prognosis of these patients might be improved when correcting decreased pretherapeutic hemoglobin values by administering erythropoietin. METHOD: In a prospective placebo-controlled double-blind study (Cochrane "evidence-based medicine" level Ib) the effect of erythropoietin was analyzed in patients with locally advanced head or neck tumours with low blood hemoglobin values (women: < 12 g/dL; men: < 13 dL) and a Karnofski value of > 60 following primary definite or adjuvant radiotherapy (up to 70 Gy). The time to local tumour progression and survival was evaluated. Kaplan-Maier estimates were applied and, the relative risk of well-known prognostic factors tested for with a Cox Proportional Hazards model. RESULTS: 157 patients of the Freiburg University ENT-clinic were recruited from 1997 to 2001. Study conduct was performed according to the GCP guidelines. A rapid increase of the blood hemoglobin value happened during the first five weeks of treatment under epoetin beta. Placebo patients experienced only minor changes of the hemoglobin value. Following adjuvant radiotherapy local tumour control probability at two years was 68 % +/- 7 % and 72 +/- 7 % for placebo and epoetin beta patients, respectively (p = 0.64). Patients who had undergone primary definite radiation experienced a local control probability of 36 % +/- 11 % in the placebo arm after two years, compared to epoetin beta with 23 % +/- 11 % (p = 0.05). CONCLUSION: Epoetin beta resulted in prompt and stable correction of blood hemoglobin values in anemic patients with advanced head or neck tumours, but tumour control and survival was impaired particularly in patients with a high tumour burden.     

Does clinical and radiological response predict complete tumor control in N2-N3 squamous cell head and neck cancer after non-operative management of the neck?

CONCLUSION: A complete clinical and radiological response observed following chemotherapy and radiotherapy is not predictive of the absence of residual disease. Moreover, salvage neck surgery does not always seem to be an effective strategy. Consequently, early neck dissection should be advised for patients with complete clinical and radiological response (CCRR) after chemoradiotherapy for tumors with N2-N3 disease. BACKGROUND: We retrospectively reviewed the outcome of 28 patients with N2-N3 disease treated initially with chemotherapy and radiotherapy. PATIENTS AND METHODS: A neck dissection was performed for all patients with residual disease in the neck. RESULTS: A CCRR in the neck was achieved in 25 of 28 patients. The remaining three patients with residual neck mass underwent a salvage neck dissection: the pathological examination confirmed the persistence of tumoral disease. No regional failure was observed in these three patients. In 25 patients considered to have CCRR in the neck, 5 patients (20%) developed regional recurrence. Successful salvage approach was not possible for any of these patients.

Progress in head and neck cancer immunotherapy: can tolerance and immune suppression be reversed?

The incidence of squamous cell carcinoma of the head and neck (SCCHN) is greater than 40,000 cases per year in the United States, and approximately 500,000 cases annually worldwide. Despite significant advances in detection, ablation, and reconstruction, survival has not improved appreciably over the past few decades. Therefore, novel approaches are necessary to provide head and neck oncologists with a more effective armamentarium against this challenging disease. Cancer immunotherapy describes various approaches to expand and activate the immune system to control tumor growth in vivo. So far, immunotherapy appears to have had applicability in conjunction with other therapeutic interventions that treat residual tumor cells after therapy or to reduce the occurrence of second primary tumors. In particular, diseases such as SCCHN are attractive candidates for novel therapeutic approaches, since the standard treatments have not yet successfully controlled this disease with sufficiently high success rates. This article reviews adjuvant immunotherapeutic strategies currently in trials or under development for SCCHN patients, including vaccination or cytokine immunostimulation.     

Ex-vivo-chemoresponse testing of head and neck cancer: an old hat?

Reliable prediction of the chance of a successful treatment of head and neck squamous cell carcinoma by cytostatics and targeting therapies would be very valuable, since HNSCC due to their heterogenic biology mostly respond non-uniformly and moreover with low response rates. To raise the prospect of chemotherapy by using multimodal therapies usually goes hand in hand with a higher incidence of severe adverse events and acute toxicity but also chemo-associated increased cancer risk following successful treatment. In addition, the increasing numbers of treatment options without availability of reliable prognostic biomarkers for a probably successful outcome make the decision for one or the other medication to something rather like gambling. Therefore, quite early a pre-therapeutic predictive exvivo chemoresponse testing of bioptic specimens was intended. However, the results gained mostly were disillusioning and allowed not for reliable prediction of chance of successful outcome of treatment with tolerable doses of the pharmaceuticals and in particular their combinations. Predictive testing, hence, was belittled as improper for the clinical context. Based on advanced methods, some working groups reassume this subject. This review describes recent advances in ex-vivo chemoresponse testing, discusses pre-requisites which have to be fulfilled before their inclusion into decision-making, and outlines why ex-vivo chemoresponse testing probably is not an old hat.     

Can we get rid of hospital infections in head and neck surgery?

Infection rate registered on the basis of clinical symptoms and of microbiological forms in patients treated in Surgery Division, Head & Neck Cancer Department during 2001-2003, was analyzed. Total number of patients treated was 2343. In 664 preoperative microbiological cultures have been obtained from suspected areas and in 52.8% of these a pathogen has been found. Patients undergoing major surgery received a prophylactic antibiotic selected by an infection control team and Microbiology Department. If preoperative cultures showed resistance to standard prophylactic antibiotic, another was selected on the antibiogram basis. Particular attention was paid to all the elements of prophylactic against infection in the ward, examination and dressing rooms, operating theatre. In 48% of patients, mainly those after extensive, prolonged surgery, antibiotics (usually 3rd generation cephalosporins) were used for 5-7 days. During 2001, 2002 and 2003 correspondingly 148, 97 and 58 infections were registered with positive culture and infection with clinical symptoms occurred in 30, 21 and 20 patients (4%, 2,8% i 2,3%). Comparisons of hospital infection rates between different institutions are very difficult, but relatively low rate in our material and decreasing number of infections registered during consecutive years show that persistent and multifaceted prophylactic interventions can result in significant reduction of hospital infections also in patients wits contaminated surgical field.     

Cutaneous malignant melanoma in the area of the head and neck with intermediate tumor thickness: does primary site have prognostic relevance?

BACKGROUND: Tumor thickness and infiltration of malignant melanoma are the main prognostic factors for recurrence and survival. The sentinel lymph node biopsy may provide a step toward a more individual staging and therapy. It was the aim of this study to investigate the prognostic influence of the primary localization of head and neck melanoma subdivided into scalp, ear, neck, and face. To form a basis for routine sentinel lymph node biopsy in case of intermediate tumor thickness metastatic pattern of the different primary sites were analysed. METHOD: Survival rates depending on primary tumor site of 51 patients with cutaneous malignant melanoma of the head and neck were analysed. Metastatic pattern were evaluated with the help of clinical, intraoperative, pathohistologic data. RESULTS: Scalp and ear melanoma were found to be higher risk lesions with a 5-year survival rate of 28% and 59% respectively. Melanoma of the neck and face had a 5-year survival rate of 75% and 78% respectively. In two cases of ear melanoma lymph node metastases could be demonstrated in unusual sites by skipping the first draining basin. In three cases bilateral metastases could be shown histologically as opposed to clinical prediction. CONCLUSIONS: Localization of cutaneous malignant melanoma of the head and neck is a prognostic factor for survival. Because of the discordancy between clinical prediction and lymphatic drainage pattern sentinel lymph node biopsy improves accuracy of diagnostic and therapeutic procedures.     

The integrated PET/CT: technological advance in diagnostics of head and neck recurrencies and CUP?

BACKGROUND: In the last years (18)F-Fluoro-deoxy-glucose (FDG)-positron emission tomography (PET) worked satisfactorily as auxiliary method in order to show recurrency of head and neck tumors and to detect primary tumors in case of CUP especially when CT and MR imaging failed to identify the tumor accurately. The correlation of FDG hypermetabolism and anatomical structures is now provided by a new technology which is integrating PET and CT: Integrated PET/CT represents a new technical development, which combines the advantages of CT and PET. PATIENTS: In a retrospective investigation 84 non selected PET/CT studies of 83 patients with recurrent head and neck disease and CUP were critically analyzed. RESULTS: 33 cases had positive PET findings. 5 of these 33 cases showed false-positive findings. In 51 PET studies there was not found any sign of suspicious FDG hypermetabolism. CONCLUSION: Integrated PET/CT delivers substantial progress in detecting tumor localization. False positive findings have to be considered and therefore indications should be strictly limited to special cases of head and neck tumor recurrency, cases with complex anatomical sites and CUP.     

Surgical margins in head and neck squamous cell carcinoma: what is ‘close’?

The aim of this systematic review is to evaluate the definition of close margin in head and neck squamous cell carcinoma (HNSCC), and its possible prognostic significance. An appropriate string was run on PubMed to retrieve articles discussing the ‘close’ surgical margin issue in HNSCC. A double cross-check was performed on citations and full-text articles retrieved. In total, 348 articles were identified. Further references were included by using the option “Titles in your search terms” option in PubMed. 15 papers were finally included for qualitative synthesis. In vocal cord surgery of HNSCC, a close margin could be considered to be ≤1 mm, in the larynx ≤5 mm, in the oral cavity ≤4 mm, and in the oropharynx ≤5 mm. In each patient, the choice of extent of close margin should be balanced against general condition, tumor stage, and functional issues to indicate appropriate adjuvant therapy.
