Population-based risk assessment of second primary cancers following a first head and neck cancer: patterns of association and difficulties of its analysis.

PURPOSE: The diagnosis of a second primary cancer (SPC) is a major concern in the follow-up of survivors of a primary head and neck cancer (HNC), but the anatomic subsites in the head and neck area are close, making it difficult to distinguish a SPC of a recurrence and therefore register it correctly. METHODS: We performed a retrospective cohort study using data from two population-based cancer registries in Catalonia, Spain: the Tarragona Cancer Registry and the Girona Cancer Registry. All patients diagnosed with HNC during the period 1994-2013 were registered and followed-up to collect cases of SPC. We analysed the standardized incidence ratio (SIR) and the excess absolute risk (EAR) to determine the risk of second malignancies following a prior HNC. RESULTS: 923 SPC were found in a cohort of 5646 patients diagnosed of a first head and neck cancer. Men had an increased risk of a SPC with a SIR of 2.22 and an EAR of 216.76. Women also had an increased risk with a SIR of 2.02 and an EAR of 95.70. We show the risk for different tumour sites and discuss the difficulties of the analysis. CONCLUSION: The risks of a SPC following a prior HNC in Tarragona and Girona are similar to those previously found in other similar cohorts. It would appear to be advisable to make a revision of the international rules of classification of multiple tumours, grouping the sites of head and neck area with new aetiological criteria to better determine and interpret the risks of SPC obtained in these studies.

A population perspective on the use of external beam radiotherapy in Catalonia, Spain.

PURPOSE: To assess the use of external beam radiotherapy in Catalonia (Spain), overall and by health management area. METHODS: We assessed radiotherapy treatments in a cohort of patients diagnosed with cancer from 2009 to 2011, using the population-based cancer registries in Girona and Tarragona. Participants had to have a minimum follow-up of 5 years from the time the cancer registry database was linked to the catalan health service database for financing radiation oncology. Outcomes included the proportion of patients receiving radiotherapy within 1 and 5 years of diagnosis. A log-binomial model was used to assess age-related trends in the use of radiotherapy by tumour site. Finally, we calculated the standardized utilization rate and 95% confidence intervals by health management area covered by the radiation oncology services, using indirect methods. RESULTS: At 1 and 5 years from diagnosis, 21.4 and 24.4% of patients, respectively, had received external beam radiotherapy. Patients aged 40-64 years had the most indications for the treatment, and there was a negative correlation between the patients' age and the use of radiotherapy for most tumour sites (exceptions were cervical, thyroid, and uterine cancers). There were no statistically significant differences in the use of radiotherapy according to th health management area. CONCLUSIONS: Population-based data show that external beam radiotherapy is underutilized in Catalonia. This situation requires a careful analysis to understand the causes, as well as an improvement of the available resources, oriented toward achieving realistic targets for the optimal use of external beam radiotherapy in our country.

Detection of incident breast and colorectal cancer cases from an administrative healthcare database in Catalonia, Spain.

OBJECTIVE: To validate the Catalan minimum basic data set (MBDS) of hospital discharges as an information source for detecting incident breast (BC) and colorectal cancer (CRC), against the Hospital del Mar Cancer Registry (RTHMar) in Barcelona (Spain) as the gold standard. METHODS: Using ASEDAT software (Analysis, Selection and Extraction of Tumour Data), we identified Catalan public hospital discharge abstracts in patients with a first-time diagnosis of BC and CRC in the years 2005, 2008, and 2011, aggregated by unique patient identifiers and sorted by date. Once merged with the RTHMar database and anonymized, tumour-specific algorithms were validated to extract data on incident cases, tumour stage, surgical treatment, and date of incidence. RESULTS: MBDS had a respective sensitivity and positive predictive value (PPV) of 78.0% (564/723) and 90.5% (564/623) for BC case detection; and 83.9% (387/461) and 94.9% (387/408) for CRC case detection. The staging algorithms overestimated the proportion of local-stage cases and underestimated the regional-stage cases in both cancers. When loco-regional stage and surgery were combined, sensitivity and PPV reached 98.3% and 99.8%, respectively, for BC and 96.4% and 98.4% for CRC. The differences between dates of incidence between RTHMar and MBDS were greater for BC cases without initial surgery, whereas they were generally smaller and homogeneous for CRC cases. CONCLUSIONS: The MBDS is a valid and efficient instrument to improve the completeness of a hospital-based cancer registry (HBCR), particularly in BC and CRC, which require hospitalization and are predominantly surgical.

Cause-specific mortality after a breast cancer diagnosis: a cohort study of 10,195 women in Girona and Tarragona.

INTRODUCTION: Evidence suggests an excess of long-term mortality due to cardiovascular diseases, second tumours and other causes in patients diagnosed with invasive breast cancer (BC). Our aim was to assess this risk of death in a cohort of patients diagnosed with BC in Girona and Tarragona, northeastern Spain. MATERIALS AND METHODS: Using data from the cancer registries in these areas, a population-based cohort study was carried out including all the women diagnosed with BC during 1985-2004 and followed up until December 31st 2014 (N = 10,195). The standardised mortality ratios (SMRs) were calculated for causes other than BC in the cohort at 10 years (periods 1985-1994/1995-2004) and 20 years (period 1985-1994). The impact of competing causes of death in the long-term survival was evaluated through competing risk analysis. RESULTS: The SMRs at 10 and 20 years for all-cause mortality, except BC, were 1.21 and 1.22. The main causes of mortality showing statistically significant SMR at 10 years were other tumours (colon, lung, corpus uteri, ovary, and haematological), diabetes mellitus, diseases of the nervous system, cardiovascular diseases (after BC, the second competing cause of death among patients diagnosed > 69 years) and diseases of the kidney. Globally, the 10-year SMR was higher in the first period. After 20 years of follow-up (1985-1994 cohort), there were 48.5 excess deaths per 10,000 patient-years for causes other than BC. CONCLUSIONS: Women who did not die from BC at 10 or 20 years after the BC diagnosis had 20% higher risk of dying from other causes than women without BC. This excess risk must be clinically considered during 20 years after the BC diagnosis.

Influence of age on variation in patterns of care in patients with rectal cancer in Catalonia (Spain).

BACKGROUND: Population ageing is a relevant concern in people diagnosed with rectal cancer. This study evaluates the adherence to clinical practice guidelines (CPGs) and patient outcomes in rectal cancer, with a particular focus on variation according to age. METHODS: This is a multicentre retrospective cohort study of all patients surgically treated for the first time for primary rectal cancer with curative intent in public hospitals in Catalonia during two study periods: first, with data from 2005 to 2007, and then with data from 2011 to 2012. We obtained the study data through a comprehensive review of patients' clinical records. Information on diagnosis, treatment and follow-up was collected and then compared with the relevant CPGs. We then performed a descriptive analysis of the categorical variables followed by a univariate and multivariate logistic regression analysis to calculate the odds ratio. Finally, we calculated the recurrence and death rates per person-year at 2 years' follow-up. RESULTS: In total, 3770 people were included in this study. The participants aged 70 and under were more likely to receive neoadjuvant therapy than those aged over 80 (2005/2007, 63 vs 17.4% p < 0.001; 2011/2012, 72 vs 41.1% p < 0.001); however, in the second study period there was less imbalance between the two groups in this regard, showing improved administration of neoadjuvant therapy in the elderly. The quality of surgery was suboptimal in a larger proportion of the elderly population, and the choice of surgical technique was dependent to some extent on the age of the participant. Recurrence and survival rates were significantly better in the second study period. CONCLUSIONS: Compared to younger patients, the most elderly were less likely to receive the recommended adjuvant treatment, laparoscopy and total mesorectal excision. However, we observed improved adherence to the recommended treatment regimen in the most elderly participants, resulting in decreased recurrence and increased survival rates in this population.

Long-term crude probabilities of death among breast cancer patients by age and stage: a population-based survival study in Northeastern Spain (Girona-Tarragona 1985-2004).

BACKGROUND: We provide population-based long-term survival indicators of breast cancer patients by quantifying the observed survival, and the probabilities of death due to breast cancer and to other causes by age and tumor stage at diagnosis. METHODS: We included a total of 10,195 female patients diagnosed before 85 years with invasive primary breast cancer in Girona and Tarragona during the periods 1985-1994 and 1995-2004 and followed-up until December 31st 2014. The survival indicators were estimated at 5, 10, 15 and 20 years of follow-up comparing diagnostic periods. RESULTS: Comparing diagnostic periods: I) the probability of death due to other causes did not change; II) the 20-year survival for women diagnosed ≤ 49 years increased 13% (1995-2004 = 68%; 1985-1994:55%), whereas their probability of death due to breast cancer decreased at the same pace (1995-2004 = 29%; 1985-1994 = 42%); III) at 10 years of follow-up, decreases in the probabilities of death due to breast cancer across age groups switched from 11 to 17% resulting in a risk of death reduction of 19% after adjusting by stage. During 1995-2004, the stage-specific 10-year probabilities of death due to breast cancer switched from: 3-6% in stage I, 18-20% in stage II, 34-46% in stage III and surpassed 70% in stage IV beyond 5 years after diagnosis. CONCLUSIONS: In our study, women diagnosed with breast cancer had higher long-term probability to die from breast cancer than from other causes. The improvements in treatment and the lead-time bias in detecting cancer in an early stage resulted in a reduction of 19% in the risk of death between diagnostic periods.

Germline promoter hypermethylation in BRCA1 and BRCA2 genes is not present in hereditary breast cancer patients.

PURPOSE: Germline promoter hypermethylation of BRCA1 and BRCA2 genes is an alternative event of gene silencing that has not been widely investigated in hereditary breast and ovarian cancer (HBOC) syndrome. METHODS: We analyzed germline BRCA promoter hypermethylation in HBOC patients with and without BRCA mutations and control subjects, using a recently developed BRCA methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) assay. RESULTS: Neither the patients tested nor the control subjects showed germline hypermethylation of the BRCA1 and BRCA2 promoter regions analyzed. CONCLUSIONS: Despite the results achieved at somatic levels by other researchers, these were not confirmed in our study at the germline level. Our results show the need to establish more predictive CpG sites in the BRCA promoter regions to optimize the MS-MLPA assay for the detection of germline hypermethylation as an effective pre-screening tool for whole-BRCA genetic analysis in HBOC, because we can not rule out the existence of germline promoter hypermethylation in BRCA.

Predicting the cancer burden in Catalonia between 2015 and 2025: the challenge of cancer management in the elderly.

BACKGROUND: Developing effective cancer control programmes requires information on the future cancer burden in an ageing population. In our study we predicted the burden of cancer in Catalonia from 2015 to 2025. METHODS: Bayesian age-period-cohort models were used to predict the burden of cancer from 2015 to 2025 using incidence data from the Girona and Tarragona cancer registries and cancer mortality data from the Catalan mortality registry. Using the Bashir-Estève method, we divided the net change in the number of cases between 2015 and 2025 into changes due to population size (S), cancer risk (R) and age (A) distribution. RESULTS: By 2025, there will be 21,743 new cancer cases in men (40% aged > 74 years) and 17,268 in women (37% aged > 74 years). More than 40% of the new cases will be diagnosed among population aged 74 and older in prostate, colorectal, lung, bladder, pancreatic and stomach cancers in men, and in colorectal, pancreatic and bladder cancers and leukaemia in women. During 2015-2025, the number of new diagnoses will increase by 5.5% in men (A + R + S = 18.1% - 13.3% + 0.7% = 5.5%) and 11.9% in women (A + R + S = 12.4% - 1.1% + 0.6% = 11.9%). Overall cancer mortality rates will continue to decrease during 2015-2025. Lung cancer will be the most lethal cancer among men (N = 2705) and women (N = 1174). CONCLUSIONS: The increase in the number of cancer cases in Catalonia from 2015 to 2025 will mostly affect the elderly, prompting the need for increased collaboration between geriatricians and oncologists.

Assessing predicted age-specific breast cancer mortality rates in 27 European countries by 2020.

BACKGROUND: We assessed differences in predicted breast cancer (BC) mortality rates, across Europe, by 2020, taking into account changes in the time trends of BC mortality rates during the period 2000-2010. METHODS: BC mortality data, for 27 European Union (EU) countries, were extracted from the World Health Organization mortality database. First, we compared BC mortality data between time periods 2000-2004 and 2006-2010 through standardized mortality ratios (SMRs) and carrying out a graphical assessment of the age-specific rates. Second, making use of the base period 2006-2012, we predicted BC mortality rates by 2020. Finally, making use of the SMRs and the predicted data, we identified a clustering of countries, assessing differences in the time trends between the areas defined in this clustering. RESULTS: The clustering approach identified two clusters of countries: the first cluster were countries where BC predicted mortality rates, in 2020, might slightly increase among women aged 69 and older compared with 2010 [Greece (SMR 1.01), Croatia (SMR 1.02), Latvia (SMR 1.15), Poland (SMR 1.14), Estonia (SMR 1.16), Bulgaria (SMR 1.13), Lithuania (SMR 1.03), Romania (SMR 1.13) and Slovakia (SMR 1.06)]. The second cluster was those countries where BC mortality rates level off or decrease in all age groups (remaining countries). However, BC mortality rates between these clusters might diminish and converge to similar figures by 2020. CONCLUSIONS: For the year 2020, our predictions have shown a converging pattern of BC mortality rates between European regions. Reducing disparities, in access to screening and treatment, could have a substantial effect in countries where a non-decreasing trend in age-specific BC mortality rates has been predicted.

Demand for radiotherapy in Spain.

AIM: Assessing the demand for radiotherapy in Spain based on existing evidence to estimate the human resources and equipment needed so that every person in Spain has access to high-quality radiotherapy when they need it. MATERIAL AND METHODS: We used data from the European Cancer Observatory on the estimated incidence of cancer in Spain in 2012, along with the evidence-based indications for radiotherapy developed by the Australian CCORE project, to obtain an optimal radiotherapy utilisation proportion (OUP) for each tumour. RESULTS: About 50.5 % of new cancers in Spain require radiotherapy at least once over the course of the disease. Additional demand for these services comes from reradiation therapy and non-melanoma skin cancer. Approximately, 25-30 % of cancer patients with an indication for radiotherapy do not receive it due to factors that include access, patient preference, familiarity with the treatment among physicians, and especially resource shortages, all of which contribute to its underutilisation. CONCLUSIONS: Radiotherapy is underused in Spain. The increasing incidence of cancer expected over the next decade and the greater frequency of reradiations necessitate the incorporation of radiotherapy demand into need-based calculations for cancer services planning.

A consensus statement on the gender perspective in lung cancer.

Lung cancer is the most common cancer globally and has the highest mortality. Although this disease is not associated with a particular gender, its incidence is rising among women, who are diagnosed at an increasingly younger age compared with men. One of the main reasons for this rise is women taking up smoking. However, many non-smoking women also develop this disease. Other risk factors implicated in the differential development of lung cancer in women are genetic predisposition, tumour histology and molecular profile. Proportionally more women than men with lung cancer have a mutation in the EGFR gene. This consensus statement reviews the available evidence about the epidemiological, biological, diagnostic, therapeutic, social and psychological aspects of lung cancer in women.

Reoperations after primary breast conserving surgery in women with invasive breast cancer in Catalonia, Spain: a retrospective study.

BACKGROUND: Although complete tumor resection is accepted as the best means to reduce recurrence, reoperations after lumpectomy are a common problem in breast cancer. The aim of this study was to assess the reoperation rates after primary breast conserving surgery in invasive breast cancer cases diagnosed in Catalonia, Spain, between 2005 and 2011 and to identify variations based on patient and tumour characteristics. METHODS: Women with invasive incident breast cancer identified from the Patient's Hospital Discharge Database [174.0-174.9 codes of the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) as the primary diagnosis] and receiving primary breast conserving surgery were included in the study and were followed up to 3 and 12 months by collecting information about repeat breast cancer surgery. RESULTS: Reoperation rates after primary breast conserving surgery decreased from 13.0 % in 2005 to 11.7 % in 2011 at 3 months and from 14.2 % in 2005 to 12.9 % in 2011 at 12 months' follow-up. While breast conservation reoperations saw a slight, non-significant increase in the same period (from 5.7 to 7.3 % at 3 months, and from 6.0 to 7.5 % at 12 months), there was a significant decrease in radical reoperation (from 7.3 to 4.4 % at 3 months and from 8.2 to 5.4 % at 12 months). Overall, additional breast surgeries decreased among younger women. CONCLUSIONS: Despite the rise of breast conserving surgery, reoperation rates following initial lumpectomy in Catalonia decreased by 10 % at 3 and 12 months' follow-up, remaining low and almost unchanged. Ultimately, there was also a significant decrease in mastectomies.

Multidisciplinary cancer care may impact on the postoperative mortality and survival of patients with oesophageal and oesophagogastric junction cancer: a retrospective cohort study.

BACKGROUND: Modern management of Oesophageal and oesophagogastric junction (OGJ) cancers requires a multidisciplinary approach, which was implemented at our health centre in 2005. This study aimed to assess the impact of this change on clinical outcomes. METHODS: A retrospective cohort study was conducted, covering all patients treated for oesophageal and OGJ cancer at the cancer centre established by the Bellvitge University Hospital and Catalonian Institute of Oncology, over two time periods, i.e. 2000-2004 and 2005-2008. Descriptive and multivariate analyses were performed using survival at 1 and 3 years as dependent variables. RESULTS: Between 1 January 2000 and 31 December 2008, 586 patients were included. Number of patients with unknown stage at diagnosis was significantly reduced. Preoperative strategies at the oesophageal location clearly increased in the recent period. A multidisciplinary approach resulted in a significant reduction in surgical mortality (11.8 vs. 2 %) in the period 2005-2008. Analysis restricted to patients undergoing surgery with curative intent indicated a significant increase in 1- and 3-year survival in the latter period (68.4 vs. 89.8 and 38.2 vs. 57.1 %, respectively). Multivariate analysis showed that variables associated with improved survival were: age; tumour stage; radical intent of treatment (surgery and radical combined chemoradiotherapy); and therapeutic strategy. CONCLUSION: Better selection of patients for therapy together with improved staging resulted in a significant improvement in 1- and 3-year survival in cases undergoing surgery with curative intent. These changes would support the adoption of a multidisciplinary approach to clinical decision-making in cases of oesophageal and OGJ cancer.

Time trends of cancer incidence and mortality in Catalonia during 1993-2007.

PURPOSE: To describe time trends of cancer in Catalonia, Spain, during the period 1993-2007. METHODS/PATIENTS: Data have been provided by two population-based cancer registries, Girona and Tarragona, and the Catalan mortality registry. Cancer incidence in Catalonia has been estimated through modeling methods using data from these health structures. RESULTS: During 2003-2007, there were 20,042 cancer cases and 9,842 deaths per year among men and 13,673 new cancer cases and 5,882 deaths among women. The most frequent incident cancers among men were prostate (N = 4,258), lung (N = 3,021), colorectal (N = 3,007) and bladder (N = 2,238), whereas among women they were breast (N = 3,907), colorectal (N = 2,088), corpus uteri (N = 734) and lung (N = 527). During 1993-2007, age-standardized incidence rates (ASIRs) rose 1.2 % per year among men [prostate (6.3 %), testis (5.7 %), kidney (2.9 %), liver (2.2 %) and colorectal (2.1 %)]. ASIRs decreased for stomach (-2.9 %), oral cavity and pharynx (-2.8 %), larynx (-2.7 %) and esophagus (-2 %). Among women, ASIRs only rose for lung (5.2 %), kidney (3.1 %), oral cavity and pharynx (2.6 %) and thyroid (1.6 %). ASIRs decreased for corpus uteri (-2.3 %), stomach (-1.7 %) and ovary (-1.6 %). Cancer mortality decreased -1.3 % per year among men and -2.1 % among women during the same period. CONCLUSION: Among men, the decrease of incidence/mortality of tobacco-related tumors was related to a reduction of smoking prevalence. Among women, the stabilization of breast cancer incidence and the rise of lung cancer incidence are similar to that observed in most European regions. These results allow assessing the effectiveness of public health strategies and they pose new frontiers for cancer control in Catalonia.

Temporal trends of incidence and survival of sarcoma of digestive tract including Gastrointestinal Stromal Tumours (GIST) in two areas of the north-east of Spain in the period 1981-2005: a population-based study.

INTRODUCTION: The diagnostic approach of Gastrointestinal Stromal Tumours (GIST) was established in 2002. Before this, GIST had been classified with a wide range of histological terms. This fact and the consideration of potential malignity of all these tumours led to a false perception of an increasing incidence. PURPOSE: This study aimed at evaluating the accuracy in registration of sarcoma of digestive tract and GIST and to elucidate the trends of incidence and survival of those. MATERIALS AND METHODS: We used data from two population-based cancer registries in Spain. In the Girona's Cancer Registry we previously reclassified all sarcoma of digestive tract performing c-kit to confirm GIST and analysed the time period 1994-2005. In Tarragona's Cancer Registry, where we analysed the time period 1981-2005, this reclassification was not done. RESULTS: We obtained a significant increasing trend in incidence of all sarcoma of digestive tract in the Tarragona Cancer Registry database, with an annual per cent of change of 3.87 but a non-statistically significant trend in incidence in the Girona Cancer Registry database. The incidence of GIST in Girona Cancer Registry was 1.24 cases/100,000 inhabitants/year. Survival rates did not change in time and was high in less aggressive GIST. The 5-year relative survival for low, intermediate and high risk of malignant behaviour GIST groups were, respectively, 80.5, 85.6 and 64.6 %. CONCLUSIONS: The increase in the incidence of GIST could be explained by the improvement in their diagnosis and registration. The survival of low and intermediate risk of malignant behaviour is high and close to normal population survival.

Cancer incidence and mortality projections up to 2020 in Catalonia by means of Bayesian models.

PURPOSE: To predict the burden of cancer in Catalonia by 2020 assessing changes in demography and cancer risk during 2010-2020. METHODS/PATIENTS: Data were obtained from Tarragona and Girona cancer registries and Catalan mortality registry. Population age distribution was obtained from the Catalan Institute of Statistics. Predicted cases in Catalonia were estimated through autoregressive Bayesian age-period-cohort models. RESULTS: There will be diagnosed 26,455 incident cases among men and 18,345 among women during 2020, which means an increase of 22.5 and 24.5 % comparing with the cancer incidence figures of 2010. In men, the increase of cases (22.5 %) can be partitioned in three components: 12 % due to ageing, 8 % due to increase in population size and 2 % due to cancer risk. In women, the role of each component was 9, 8 and 8 %, respectively. The increased risk is mainly expected to be observed in tobacco-related tumours among women and in colorectal and liver cancers among men. During 2010-2020 a mortality decline is expected in both sexes. CONCLUSION: The expected increase of cancer incidence, mainly due to tobacco-related tumours in women and colorectal in men, reinforces the need to strengthen smoking prevention and the expansion of early detection of colorectal cancer in Catalonia.

Preliminary analysis of the resources in brachytherapy in Europe and its variability of use.

PURPOSE: The main objective of the program <> is to establish a group with detailed information on brachytherapy throughout Europe. METHODS: The data was compiled by the general coordinator, the ESTRO, and the <> through a website. RESULTS: A total of 32 countries reported data from at least 50% of their centres (criteria of inclusion). Countries were grouped in three categories based on the time of incorporation to the European Union. The majority of treatments belonged to gynaecological tumours. A large spread was found regarding workload of specialists depending on centre and group. CONCLUSION: Collection of information by a website is a feasible methodology. An increase in brachytherapy treatment was observed in all 3 groups by a rate of more than 20% (year 2002 versus year 1997). These results advocate for the continuation of the PCBE study to demonstrate the development in the field, such as an increase or decrease of patient numbers per tumour category.

Cosmetic outcome of breast conservative treatment for early stage breast cancer.

PURPOSE: To evaluate the cosmetic outcome of breast conservative therapy and to examine the degree of agreement between the patients' and oncologists' ratings. We also analyze the influence of several factors on cosmesis. METHODS AND MATERIALS: We retrospectively evaluated 145 patients with primary breast cancer treated by local excision and radiotherapy between January 2000 and May 2001. Cosmetic outcome was evaluated by doctors and patients and was scored as excellent, good, fair or poor. RESULTS: 73% of patients rated cosmesis as excellent or good while the percentage was 71% when rated by radiation oncologists. The degree of cosmesis concordance evaluated by oncologists and patients was low (kappa = 0.3). In our study the variables which significantly influence on the cosmetic outcome were concomitant adjuvant chemotherapy (p = 0.04) and radiation therapy boost, either by electron beam or brachytherapy (p = 0.013). CONCLUSION: The cosmetic outcome of breast conserving therapy was good. There was a similar rating by the patient and radiation oncologist, but the level of concordance between patients and doctors was low. Factors that significantly influence the cosmesis appear to be concomitant adjuvant chemotherapy and radiation therapy boost.

The syndrome of cerebral infarction following herpes zoster ophthalmicus.

Delayed contralateral hemiparesis following herpes zoster (HZ) ophthalmicus is an unusual but distinct clinical entity, presumably caused by HZ-induced arteritis with subsequent cerebral infarction. We report a case showing typical clinical and angiographic findings.
