Head and neck squamous cell carcinomas are common lesions, related to chronic smoking and drinking behaviors. But in contrast to other cancers, effect of obesity on occurrence, diagnosis, treatment and prognosis of these tumors remains to date unknown. This is a retrospective review of 111 obese patients (sex ratio=6.4, median age=54.5 year old), treated between 1999 and 2007. Risk factors, tumoral localization and staging (41% stage I-II) were the same as in general population. However, we found 26.1% difficult pan-endoscopies, 54% ACE-27 comorbidity scores ≥2 and 22.5% misstaged cervical lymphadenopathy. Treatment was based upon surgery (61%) or radiotherapy-chemotherapy (39%), and 37% of patients developed complications. Median follow up (38 months) and five-year overall survival (50%) are comparable to data in non obese patients. Although no direct relation between obesity and squamous cell carcinomas of the head and neck was found, obesity causes problems in tumor assessment and increases surgical complications rate. However, final good therapeutic tolerance and overall survival rate show that these patients should be managed like normal weighted ones. Receiving optimal treatments allow them to anticipate equivalent outcome as in general population., (Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.)

The link between head and neck squamous cell cancer (HNSCC), especially oropharyngeal cancer, and HPV has become established. HPV16 is the most common genotype in these tumours but HPV6 and HPV11 can also be found in a minority of these cancers, implying that these low-risk HPV types are not entirely benign in the head and neck region. HPV status is also associated with p16 expression and HPV+ tumours are less likely to harbour p53 mutations. HPV DNA is closely associated with poorly differentiated cancers, positive lymph nodes and late-stage disease, which all indicate poor prognosis. Contradictory to this, patients with HPV+ HNSCC seem to have significantly improved response to chemotherapy and radiotherapy as compared with HPV-negative tumours. Interestingly, the risk factors of HNSCC are the same as for HPV, including the number of sexual partners, younger age at first sexual intercourse, practice of oral sex, history of genital warts and younger age.

Introduction: A significant proportion of lung cancer patients receive no anticancer treatment. This varies from 19% in USA, 33% in Australia, 37% in Scotland, and 50% in Ireland. The aim of this study was to identify the reasons behind this., Methods: The Lung Cancer Multidisciplinary Meeting (MDM) in South-West Sydney prospectively collects data on all patients presented. All new lung cancer patients presented between December 1, 2005, and December 31, 2007, were reviewed. Patients were assigned optimal treatment based on evidence-based guidelines. Those patients in whom guidelines recommended no treatment (GNT) were compared with those whom the MDM recommended no treatment (MNT) and with those who actually received no treatment (ANT)., Results: There were 335 patients with a median age of 69 years. A total of 82% had non-small cell lung cancer, 14% had small cell lung cancer, and 4% had no pathologic diagnosis. Eighty-five percent had locally advanced or metastatic disease. GNT was recommended in 4% (n = 13), MNT in 10% (n = 32) but ANT comprised 20% (n = 66). The differences between GNT and MNT were mainly due to patient comorbidities and clinician decision, but the differences between MNT and ANT were due to patient preference and declining performance status. In multivariate analysis, older age, poorer Eastern Cooperative Oncology Group status, non-small cell lung cancer, and non-English language predicted for ANT., Conclusions: The proportion of patients with lung cancer receiving no treatment is greater than that predicted by guidelines or recommended by the MDM but lower than that described in population-based studies suggesting that MDMs can improve treatment utilization in lung cancer.

Human papillomavirus (HPV) genotypes and HPV DNA load were analysed in cervical smears from 76 human immunodeficiency virus (HIV)-positive and 54 HIV-negative women. The prevalence of genotypes was similar for all women, with the exception of HPV62, which was over-represented in HIV-positive samples. HIV-positive women showed a higher prevalence of multiple genotypes that correlated neither with CD4(+) T-cell counts nor with cervical dysplasia. No significant differences were observed in terms of total or single-type HPV DNA load. The HPV DNA load in both HIV-positive and HIV-negative women was significantly higher in squamous intra-epithelial lesions than in negative Pap smears.

Aspergilloma is a fungal ball that usually forms in a preformed stationary cavity, mostly in lung and paranasal sinuses. We report a rare case of primary orbital Aspergilloma following exenteration for an invasive ocular surface squamous neoplasia, clinically mimicking a recurrence of the tumor. The fungal ball showed the presence of conidiophores with a globular head and a complete row of uni and biserrate phialides, suggestive of Aspergillus flavus species. The exposure to air in the orbit, possibly promoted the formation of conidiophores, which are normally seen when the organism is located in air cavities.

We herein report about 2 heart transplant patients undergoing surgical resection for esophageal cancer. Both were long-term survivors after orthotopic heart transplantation for dilated cardiomyopathy. One patient underwent a transthoracic esophagectomy and gastric pull-up for an early squamous cell carcinoma of the infracarinal esophagus. The second patient underwent a resection of the cervical esophagus and interposition of a free jejunal segment after neoadjuvant radiochemotherapy for a locally advanced squamous cell carcinoma in the cervical esophagus.
