RESUMO

BACKGROUND: Primary endocrine therapy may be an alternative treatment for less fit women with oestrogen receptor (ER)-positive breast cancer. This study compared quality-of-life (QoL) outcomes in older women treated with surgery or primary endocrine therapy. METHODS: This was a multicentre, prospective, observational cohort study of surgery or primary endocrine therapy in women aged over 70 years with operable breast cancer. QoL was assessed using European Organisation for Research and Treatment of cancer QoL questionnaires QLQ-C30, -BR23, and -ELD14, and the EuroQol Five Dimensions 5L score at baseline, 6 weeks, and 6, 12, 18, and 24 months. Propensity score matching was used to adjust for baseline variation in health, fitness, and tumour stage. RESULTS: The study recruited 3416 women (median age 77 (range 69-102) years) from 56 breast units. Of these, 2979 (87.2 per cent) had ER-positive breast cancer; 2354 women had surgery and 500 received primary endocrine therapy (125 were excluded from analysis due to inadequate data or non-standard therapy). Median follow-up was 52 months. The primary endocrine therapy group was older and less fit. Baseline QoL differed between the groups; the mean(s.d.) QLQ-C30 global health status score was 66.2(21.1) in patients who received primary endocrine therapy versus 77.1(17.8) among those who had surgery plus endocrine therapy. In the unmatched analysis, changes in QoL between 6 weeks and baseline were noted in several domains, but by 24 months most scores had returned to baseline levels. In the matched analysis, major surgery (mastectomy or axillary clearance) had a more pronounced adverse impact than primary endocrine therapy in several domains. CONCLUSION: Adverse effects on QoL are seen in the first few months after surgery, but by 24 months these have largely resolved. Women considering surgery should be informed of these effects.

RESUMO

BACKGROUND: Rates of surgery and adjuvant therapy for breast cancer vary widely between breast units. This may contribute to differences in survival. This cluster RCT evaluated the impact of decision support interventions (DESIs) for older women with breast cancer, to ascertain whether DESIs influenced quality of life, survival, decision quality, and treatment choice. METHODS: A multicentre cluster RCT compared the use of two DESIs against usual care in treatment decision-making in older women (aged at least ≥70 years) with breast cancer. Each DESI comprised an online algorithm, booklet, and brief decision aid to inform choices between surgery plus adjuvant endocrine therapy versus primary endocrine therapy, and adjuvant chemotherapy versus no chemotherapy. The primary outcome was quality of life. Secondary outcomes included decision quality measures, survival, and treatment choice. RESULTS: A total of 46 breast units were randomized (21 intervention, 25 usual care), recruiting 1339 women (670 intervention, 669 usual care). There was no significant difference in global quality of life at 6 months after the baseline assessment on intention-to-treat analysis (difference -0.20, 95 per cent confidence interval (C.I.) -2.69 to 2.29; P = 0.900). In women offered a choice of primary endocrine therapy versus surgery plus endocrine therapy, knowledge about treatments was greater in the intervention arm (94 versus 74 per cent; P = 0.003). Treatment choice was altered, with a primary endocrine therapy rate among women with oestrogen receptor-positive disease of 21.0 per cent in the intervention versus 15.4 per cent in usual-care sites (difference 5.5 (95 per cent C.I. 1.1 to 10.0) per cent; P = 0.029). The chemotherapy rate was 10.3 per cent at intervention versus 14.8 per cent at usual-care sites (difference -4.5 (C.I. -8.0 to 0) per cent; P = 0.013). Survival was similar in both arms. CONCLUSION: The use of DESIs in older women increases knowledge of breast cancer treatment options, facilitates shared decision-making, and alters treatment selection.

RESUMO

BACKGROUND: Breast cancer surgery in older women is variable and sometimes non-standard owing to concerns about morbidity. Bridging the Age Gap in Breast Cancer is a prospective multicentre cohort study aiming to determine factors influencing treatment selection and outcomes from surgery for older patients with breast cancer. METHODS: Women aged at least 70 years with operable breast cancer were recruited from 57 UK breast units between 2013 and 2018. Associations between patient and tumour characteristics and type of surgery in the breast and axilla were evaluated using univariable and multivariable analyses. Oncological outcomes, adverse events and quality-of-life (QoL) outcomes were monitored for 2 years. RESULTS: Among 3375 women recruited, surgery was performed in 2816 patients, of whom 24 with inadequate data were excluded. Sixty-two women had bilateral tumours, giving a total of 2854 surgical events. Median age was 76 (range 70-95) years. Breast surgery comprised mastectomy in 1138 and breast-conserving surgery in 1716 procedures. Axillary surgery comprised axillary lymph node dissection in 575 and sentinel node biopsy in 2203; 76 had no axillary surgery. Age, frailty, dementia and co-morbidities were predictors of mastectomy (multivariable odds ratio (OR) for age 1·06, 95 per cent c.i. 1·05 to 1·08). Age, frailty and co-morbidity were significant predictors of no axillary surgery (OR for age 0·91, 0·87 to 0·96). The rate of adverse events was moderate (551 of 2854, 19·3 per cent), with no 30-day mortality. Long-term QoL and functional independence were adversely affected by surgery. CONCLUSION: Breast cancer surgery is safe in women aged 70 years or more, with serious adverse events being rare and no mortality. Age, ill health and frailty all influence surgical decision-making. Surgery has a negative impact on QoL and independence, which must be considered when counselling patients about choices.


ANTECEDENTES: La cirugía del cáncer de mama en mujeres mayores es variable y, a veces, no estandarizada debido a las reservas que origina la morbilidad quirúrgica. Bridging the Age Gap in Breast Cancer es un estudio de cohortes, prospectivo, multicéntrico cuyo objetivo fue determinar los factores que influyen en la selección del tratamiento y en los resultados de la cirugía en pacientes mayores con cáncer de mama. MÉTODOS: Se reclutaron mujeres de > 70 años de edad con cáncer de mama operable atendidas en 56 unidades de mama del Reino Unido entre 2013-2018. Los datos sobre las características de la paciente y del tumor se correlacionaron con el tipo de cirugía en la mama y en la axila mediante análisis univariable y multivariable. Se controlaron los resultados oncológicos, los eventos adversos y los resultados en cuanto a la calidad de vida durante 2 años. RESULTADOS: De 3.375 mujeres reclutadas, se realizó una intervención quirúrgica en 2.816 pacientes. Hubo 62 tumores bilaterales, por lo que se analizan 2.854 procedimientos. La mediana de edad fue de 76 años (rango 70-95). En 1.138 pacientes se realizó una mastectomía y en 1.798 cirugía conservadora de la mama. En cuanto a la cirugía de la axila, en 575 pacientes se realizó una linfadenectomía, en 2.203 una biopsia de ganglio centinela y en 76 no se realizó ningún procedimiento. Los factores predictores de mastectomía fueron la edad, la fragilidad, la demencia y las comorbilidades (riesgo relativo, RR 1,06; i.c. del 95% 1,05-1,08), mientras que para la cirugía axilar los factores predictores fueron la fragilidad y las comorbilidades (RR 0,91; i.c. del 95% 0,87-0,96). La tasa de efectos adversos fue moderada (551/2854; 19,3%), sin mortalidad a los 30 días. La calidad de vida a largo plazo y la independencia funcional se vieron negativamente afectadas por la cirugía. CONCLUSIÓN: La cirugía de cáncer de mama es segura, con escasos efectos adversos graves y sin mortalidad. La edad, las comorbilidades y la fragilidad tienen impacto en la toma de decisiones quirúrgicas. La cirugía tiene una repercusión negativa en la calidad de vida e independencia funcional, hechos que deben ser tenidos en cuenta al aconsejar a las pacientes sobre las opciones terapéuticas.

RESUMO

INTRODUCTION: The aim of this study was to analyze global variations in the level of cancer-related research activity and correlate this with cancer-specific mortality. METHODS: The SCOPUS database was explored to obtain data relating to the number of cancer-related publications per country. Cancer-specific mortality rates were obtained from the World Health Organization. Global variations in the level of scholarly activity were analyzed and correlated with variations in cancer-specific mortality. RESULTS: Data for 142 countries were obtained and significant variations in the level of research activity was noted. The level of research activity increased with rising socio-economic status. The United States was the most prolific country with 222,300 publications followed by Japan and Germany. Several countries in different regions of the world had a low level of research activity. An inverse relationship between the level of research activity and cancer-specific mortality was noted. This relationship persisted even in countries with a low level of research activity. The socioeconomic status of a nation and geographic location (continent) had a mixed influence with an overall apparent correlation with cancer-related research activity. CONCLUSION: This study demonstrates significant global variation in the level of cancer-related research activity and a correlation with cancer-specific mortality. The presence of a minimum set of standards for research literacy, as proposed by the European Society of Surgical Oncology and the Society of Surgical Oncology may contribute to enhanced research activity and improve outcomes for cancer patients worldwide.

RESUMO

BACKGROUND: The ability to provide optimal care to cancer patients depends on awareness of current evidence-based practices emanating from research or involvement in research where circumstances permit. The significant global variations in cancer-related research activity and its correlation to cancer-specific outcomes may have an influence on the care provided to cancer patients and their outcomes. The aim of this project is to develop a global curriculum in research literacy for the surgical oncologist. MATERIALS AND METHODS: The leadership of the Society of Surgical Oncology and European Society of Surgical Oncology convened a global curriculum committee to develop a global curriculum in research literacy for the Surgical Oncologist. RESULTS: A global curriculum in research literacy is developed to incorporate the required domains considered to be essential to interpret the published research or become involved in research activity where circumstances permit. The purpose of this curriculum is to promote research literacy for the surgical oncologist, wherever they are based. It does not mandate direct research participation which may not be feasible due to restrictions within the local health-care delivery environment, socio-economic priorities and the educational environment of the individual institution where they work. CONCLUSIONS: A global curriculum in research literacy is proposed which may promote research literacy or encourage involvement in research activity where circumstances permit. It is hoped that this will enhance cancer-related research activity, promote awareness of optimal evidence-based practices and improve outcomes for cancer patients globally.

RESUMO

In 2014, the Food and Drug Administration approved a new human papillomavirus 9-valent vaccine (9vHPV), targeting nine HPV types: HPV types 6, 11, 16, and 18, which are also targeted by the quadrivalent HPV vaccine (qHPV), plus five additional high cancer risk HPV types (HPV types 31, 33, 45, 52, and 58). The aim of the current study was to systematically retrieve, qualitatively and quantitatively pool, as well as critically appraise all available evidence on 9vHPV from randomized controlled trials (RCTs). We conducted a systematic review of the literature on 9vHPV efficacy, immunogenicity and safety, as well as a systematic search of registered, completed, and ongoing RCTs. We retrieved and screened 227 records for eligibility. A total of 10 publications reported on RCTs' results on 9vHPV and were included in the review. Sixteen RCTs on 9vHPV have been registered on RCT registries. There is evidence that 9vHPV generated a response to HPV types 6, 11, 16 and 18 that was non-inferior to qHPV. Vaccine efficacy against five additional HPV type-related diseases was directly assessed on females aged 16-26 years (risk reduction against high-grade cervical, vulvar or vaginal disease = 96·7%, 95% CI 80·9%-99·8%). Bridging efficacy was demonstrated for males and females aged 9-15 years and males aged 16-26 years (the lower bound of the 95% CIs of both the geometric mean titer ratio and difference in seroconversion rates meeting the criteria for non-inferiority for all HPV types). Overall, 9vHPV has been proved to be safe and well tolerated. Other RCTs addressed: 9vHPV co-administration with other vaccines, 9vHPV administration in subjects that previously received qHPV and 9vHPV efficacy in regimens containing fewer than three doses. The inclusion of additional HPV types in 9vHPV offers great potential to expand protection against HPV infection. However, the impact of 9vHPV on reducing the global burden of HPV-related disease will greatly depend on vaccine uptake, coverage, availability, and affordability.

RESUMO

BACKGROUND: The significant global variations in surgical oncology training paradigms can have a detrimental effect on tackling the rising global cancer burden. While some variations in training are essential to account for the differences in types of cancer and biology, the fundamental principles of providing care to a cancer patient remain the same. The development of a global curriculum in surgical oncology with incorporated essential standards could be very useful in building an adequately trained surgical oncology workforce, which in turn could help in tackling the rising global cancer burden. MATERIALS AND METHODS: The leaders of the Society of Surgical Oncology and European Society of Surgical Oncology convened a global curriculum committee to develop a global curriculum in surgical oncology. RESULTS: A global curriculum in surgical oncology was developed to incorporate the required domains considered to be essential in training a surgical oncologist. The curriculum was constructed in a modular fashion to permit flexibility to suit the needs of the different regions of the world. Similarly, recognizing the various sociocultural, financial and cultural influences across the world, the proposed curriculum is aspirational and not mandatory in intent. CONCLUSIONS: A global curriculum was developed which may be considered as a foundational scaffolding for training surgical oncologists worldwide. It is envisioned that this initial global curriculum will provide a flexible and modular scaffolding that can be tailored by individual countries or regions to train surgical oncologists in a way that is appropriate for practice in their local environment. © 2016 Society of Surgical Oncology and the European Society of Surgical Oncology.

RESUMO

BACKGROUND: The global cancer burden is predicted to rise significantly over the next few decades. While there are several barriers to providing optimal cancer care on the global stage, some are related to the absence of an adequately trained workforce. This could be attributed in part to the significant global variations in the training of surgical oncology professionals. There are currently no published data mapping the training pathways for surgical oncologists for all countries in the world. The aims of this descriptive article are to report on the training paradigms in surgical oncology for all countries in the world, and to correlate the influence of economic standing on these training paradigms. MATERIALS AND METHODS: The training paradigms for all countries in the world were analyzed and categorized on the basis of the six World Health Organization geographic regions and economic standing stratified by the Human Development Index. RESULTS: Data on the training paradigms were obtained for 174 countries from a total of 211 (82 %). We noted extremely significant and concerning variations in the length, availability and structure of training paradigms depending on the geographic region and economic standing. CONCLUSIONS: The results of our study demonstrated significant global variations in the training paradigms of surgical oncologists. These variations call for a global curriculum which has been developed by the Society of Surgical Oncology and the European Society of Surgical Oncology. It is hoped that this curriculum will serve a role in streamlining education to tackle the rising global cancer burden. © 2016 Society of Surgical Oncology and the European Society of Surgical Oncology.

RESUMO

Colorectal cancer (CRC) is one of the most commonly diagnosed cancers in Europe and worldwide, with the peak incidence in patients >70 years of age. However, as the treatment algorithms for the treatment of patients with CRC become ever more complex, it is clear that a significant percentage of older CRC patients (>70 years) are being less than optimally treated. This document provides a summary of an International Society of Geriatric Oncology (SIOG) task force meeting convened in Paris in 2013 to update the existing expert recommendations for the treatment of older (geriatric) CRC patients published in 2009 and includes overviews of the recent data on epidemiology, geriatric assessment as it relates to surgery and oncology, and the ability of older CRC patients to tolerate surgery, adjuvant chemotherapy, treatment of their metastatic disease including palliative chemotherapy with and without the use of the biologics, and finally the use of adjuvant and palliative radiotherapy in the treatment of older rectal cancer patients. An overview of each area was presented by one of the task force experts and comments invited from other task force members.

RESUMO

BACKGROUND: Screening tools are proposed to identify those older cancer patients in need of geriatric assessment (GA) and multidisciplinary approach. We aimed to update the International Society of Geriatric Oncology (SIOG) 2005 recommendations on the use of screening tools. MATERIALS AND METHODS: SIOG composed a task group to review, interpret and discuss evidence on the use of screening tools in older cancer patients. A systematic review was carried out and discussed by an expert panel, leading to a consensus statement on their use. RESULTS: Forty-four studies reporting on the use of 17 different screening tools in older cancer patients were identified. The tools most studied in older cancer patients are G8, Flemish version of the Triage Risk Screening Tool (fTRST) and Vulnerable Elders Survey-13 (VES-13). Across all studies, the highest sensitivity was observed for: G8, fTRST, Oncogeriatric screen, Study of Osteoporotic Fractures, Eastern Cooperative Oncology Group-Performance Status, Senior Adult Oncology Program (SAOP) 2 screening and Gerhematolim. In 11 direct comparisons for detecting problems on a full GA, the G8 was more or equally sensitive than other instruments in all six comparisons, whereas results were mixed for the VES-13 in seven comparisons. In addition, different tools have demonstrated associations with outcome measures, including G8 and VES-13. CONCLUSIONS: Screening tools do not replace GA but are recommended in a busy practice in order to identify those patients in need of full GA. If abnormal, screening should be followed by GA and guided multidisciplinary interventions. Several tools are available with different performance for various parameters (including sensitivity for addressing the need for further GA). Further research should focus on the ability of screening tools to build clinical pathways and to predict different outcome parameters.

RESUMO

Head and Neck (H&N) cancer treatment can have a major detrimental impact on patient lives, and these issues can go unrecognised and be inadequately addressed. The aim of this paper is to compare the Patient Concerns Inventory (PCI) responses across age groups attending routine H&N cancer follow-up clinics with particular focus on the elderly (75 years or older). The PCI-HN data were obtained from patients attending follow-up clinics between August 2007 and January 2013. The groups for comparison were: <55 (n = 105), 55-64 (n = 170), 65-69 (n = 64), 70-74 (n = 68), and ≥75 (n = 76), the median in this last group of 79.1 years. Regarding quality of life (QoL) on first completing the PCI the elderly reported better anxiety and mood, higher social-emotional subscale scores and better overall QoL. On the PCI, being elderly did not seem to affect the total numbers of items selected, though fewer items were selected from the psychological, emotional and spiritual well-being domain, and in particular the item about fear of recurrence. Dentist and surgeon were the two health professionals most often selected that patients wished to see or be referred on to. It is possible to recognise concerns in routine clinical care, thus allowing the opportunity for intervention and support to improve the outcome for the elderly.

RESUMO

Radiotherapy (RT) is a key component of the management of older cancer patients. Level I evidence in older patients is limited. The International Society of Geriatric Oncology (SIOG) established a task force to make recommendations for curative RT in older patients and to identify future research priorities. Evidence-based guidelines are provided for breast, lung, endometrial, prostate, rectal, pancreatic, oesophageal, head and neck, central nervous system malignancies and lymphomas. Patient selection should include comorbidity and geriatric evaluation. Advances in radiation planning and delivery improve target coverage, reduce toxicity and widen eligibility for treatment. Shorter courses of hypofractionated whole breast RT are safe and effective. Conformal RT and involved-field techniques without elective nodal irradiation have improved outcomes in non-small-cell lung cancer (NSCLC) without increasing toxicity. Where comorbidities preclude surgery, stereotactic body radiotherapy (SBRT) is an option for early-stage NSCLC and pancreatic cancer. Modern involved-field RT for lymphoma based on pre-treatment positron emission tomography data has reduced toxicity. Significant comorbidity is a relative contraindication to aggressive treatment in low-risk prostate cancer (PC). For intermediate-risk disease, 4-6 months of hormones are combined with external beam radiotherapy (EBRT). For high-risk PC, combined modality therapy (CMT) is advised. For high-intermediate risk, endometrial cancer vaginal brachytherapy is recommended. Short-course EBRT is an alternative to CMT in older patients with rectal cancer without significant comorbidities. Endorectal RT may be an option for early disease. For primary brain tumours, shorter courses of postoperative RT following maximal debulking provide equivalent survival to longer schedules. MGMT methylation status may help select older patients for temozolomide alone. Stereotactic RT provides an alternative to whole-brain RT in patients with limited brain metastases. Intensity-modulated radiation therapy provides an excellent technique to reduce dose to the carotids in head and neck cancer and improves locoregional control in oesophageal cancer. Best practice and research priorities are summarised.

RESUMO

Recently, many centers have omitted routine axillary lymph node dissection (ALND) after metastatic sentinel node biopsy in breast cancer due to a growing body of literature. However, existing guidelines of adjuvant treatment planning are strongly based on axillary nodal stage. In this study, we aim to develop a novel international multicenter predictive tool to estimate a patient-specific risk of having four or more tumor-positive axillary lymph nodes (ALN) in patients with macrometastatic sentinel node(s) (SN). A series of 675 patients with macrometastatic SN and completion ALND from five European centers were analyzed by logistic regression analysis. A multivariate predictive model was created and validated internally by 367 additional patients and then externally by 760 additional patients from eight different centers. All statistical tests were two-sided. Prevalence of four or more tumor-positive ALN in each center's series (P = 0.010), number of metastatic SNs (P < 0.0001), number of negative SNs (P = 0.003), histological size of the primary tumor (P = 0.020), and extra-capsular extension of SN metastasis (P < 0.0001) were included in the predictive model. The model's area under the receiver operating characteristics curve was 0.766 in the internal validation and 0.774 in external validation. Our novel international multicenter-based predictive tool reliably estimates the risk of four or more axillary metastases after identifying macrometastatic SN(s) in breast cancer. Our tool performs well in internal and external validation, but needs to be further validated in each center before application to clinical use.

RESUMO

AIM: A meta-analysis of nonrandomized studies and one randomized trial was conducted to compare laparoscopic surgery with open surgery in the elective treatment of patients with diverticular disease. METHOD: Published randomized and controlled clinical trials that directly compared elective open (OSR) with laparoscopic surgical resection (LSR) in patients with diverticular disease were identified using the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE. End-points included 30-day mortality and morbidity and were compared by determining the relative risk ratio, odds ratio, and the absolute effects. RESULTS: Eleven nonrandomized studies of 1430 patients were identified and included in the meta-analysis. There was only one randomized study, which included 104 patients. The meta-analysis suggested that elective LSR was a safe and appropriate option for patients with diverticular disease and was associated with lower overall morbidity (P = 0.01) and minor complication rate (P = 0.008). CONCLUSION: The results of the nonrandomized study generally agreed with those of the randomized study, except for the incidence of minor complications, which was higher in both the LSR and OSR groups of the randomized study. In this study, the high overall morbidity of 42.3% reported in the LSR group is a cause for concern.

AIM: To evaluate the efficacy and safety for use of dual radioisotopes for localization of occult (impalpable) breast lesions and sentinel node biopsy as a combined technique (SNOLL) using a lower dose than previous studies. MATERIALS AND METHODS: One hundred and twenty-seven SNOLL procedures were performed. The impalpable breast lesions were localized with an intra-lesion injection of 0.2 ml of (99m)Tc MAA (1 MBq) with a particle size of 10-90 µm (radio-guided occult lesion localization, or ROLL) 1 to 4 h before surgery. Sentinel node localization was performed using 0.2 mls of (99)Tc nanocolloid (20 MBq) particle size no greater than 80 nm injected subdermally in the periareolar region within the index quadrant, the night before or the morning of surgery. RESULTS: Lesion localization was consistently achieved with a lower dose than that described in other studies without the need to use scintigraphy or additional imaging with radioopaque contrast medium. One hundred percent lesion localization with a negative clearance margin of 94.8% and 100% sentinel node localization was achieved. The use of dual radioisotopes with the lower dose used for ROLL did not compromise the localization of the impalpable lesion or the sentinel nodes. CONCLUSION: The combined use of radioisotopes for lesion and sentinel node removal is feasible and reliable with the lower radioisotope dose suggested compared with previously published studies. This method should be recommended as a standard procedure for SNOLL.

RESUMO

INTRODUCTION: Various options for axillary staging after neoadjuvant systemic therapy (NST) are available for breast cancer patients with a clinically positive axillary node (cN+). This survey assessed current practices amongst breast cancer specialists. MATERIALS AND METHODS: A survey was performed amongst members of the European Society of Surgical Oncology and two UK-based Associations: the Association of Breast Surgery and the British Association of Surgical Oncology. The survey included 3 parts: 1. general information, 2. diagnostic work-up and 3. axillary staging after NST. RESULTS: A total of 310 responses were collected: parts 1, 2 and 3 were fully completed by 282 (91%), 270 (87.1%) and 225 (72.6%) respondents respectively. After NST, 153/267 (57.3%) respondents currently perform ALND routinely and 114 (42.7%) respondents perform less invasive restaging of the axilla with possible omission of ALND. In the latter group, 85% does and 15% does not use nodal response seen on imaging to guide the axillary restaging procedure. Regarding respondents that do use imaging: 95% would perform a less invasive staging procedure in case of complete nodal response on imaging (63% sentinel lymph node biopsy (SLNB), excision of a previously marked positive node with SLNB (21%) and without SLNB (11%)). In case of no nodal response on imaging 77% would perform ALND. CONCLUSION: Current axillary staging and management practices in cN + patients after NST vary widely. To determine optimal axillary staging and management in terms of quality of life and oncologic safety, breast specialists are encouraged to include patients in clinical trials/prospective registries.

RESUMO

Colorectal cancer (CRC) is one of the commonest malignancies of Western countries, with approximately half the incidence occurring in patients >70 years of age. Elderly CRC patients, however, are understaged, undertreated and underrepresented in clinical trials. The International Society of Geriatric Oncology created a task force with a view to assessing the potential for developing guidelines for the treatment of elderly (geriatric) CRC patients. A review of the evidence presented by the task force members confirmed the paucity of clinical trial data in elderly people and the lack of evidence-based guidelines. However, recommendations have been proposed on the basis of the available data and on the emerging evidence that treatment outcomes for fit, elderly CRC patients can be similar to those of younger patients. It is hoped that these will pave the way for formal treatment guidelines based upon solid scientific evidence in the future.
