Benefits from specialised cancer care

Ovarian cancer management in an ESGO ovarian cancer center of excellence: a systematic case study of the interprofessional and interdisciplinary interaction

PURPOSE

With growing knowledge about ovarian cancer over the last decades, diagnosis, evaluation and treatment of ovarian cancer patients have become highly specialized, and an individually adapted approach should be made in each woman by interdisciplinary cooperation. The present study aims to show the variety and extent of medical specialties involved at our institution according to the European Society of Gynecologic Oncology (ESGO) Quality indicators (QI).

METHODS

A woman, diagnosed with high-grade ovarian cancer, International Federation of Gynecology and Obstetrics (FIGO) class IVb was selected for a single case observational study. The observation period (total = 22d) comprised preoperative diagnostic procedures, including imaging, the in-patient stay for cytoreductive surgery, and the postoperative course and case discussion at our interdisciplinary tumor board. Data were obtained by self-reporting and by patient file review.

RESULTS

Patient tracking demonstrated an interdisciplinary cooperation of 12 medical specialties [62 physicians (63% male, 37% female)], 8 different types of nursing staff [n = 59 (22% male, 78% female)], and 9 different types of perioperative/administrative staff (n = 23; male 17,4%, female n = 19, 82,6%). Contact with the patient was direct (n = 199; 76%) or without face-to-face interaction (n = 63; 24%).

CONCLUSION

The present study demonstrates the high diversity of physicians and the affiliated medical staff, as well as interdisciplinary intersections within teams of a specialized hospital. Matching the ESGO QIs, this report underlines the requirement of an adequate infrastructure for the complex management of advanced ovarian cancer patients. Future prospective studies are warranted to evaluate the specific procedures and actions to optimize the interprofessional and interdisciplinary workflows.

Management and outcomes of adolescent and young adult sarcoma patients: results from the French nationwide database NETSARC

BACKGROUND

The initial management of patients with sarcoma is a critical issue. We used the nationwide French National Cancer Institute-funded prospective sarcoma database NETSARC to report the management and oncologic outcomes in adolescents and young adults (AYAs) patients with sarcoma at the national level.

PATIENTS AND METHODS

NETSARC database gathers regularly monitored and updated data from patients with sarcoma. NETSARC was queried for patients (15-30 years) with sarcoma diagnosed from 2010 to 2017 for whom tumor resection had been performed. We reported management, locoregional recurrence-free survival (LRFS), progression-free survival (PFS), and overall survival (OS) in AYA treated in French reference sarcoma centers (RSC) and outside RSC (non-RSC) and conducted multivariable survival analyses adjusted for classical prognostic factors.

RESULTS

Among 3,227 patients aged 15-30 years with sarcoma diagnosed between 2010 and 2017, the study included 2,227 patients with surgery data available, among whom 1,290 AYAs had been operated in RSC, and 937 AYAs in non-RSC. Significant differences in compliance to guidelines were observed including pre-treatment biopsy (RSC: 85.9%; non-RSC 48.1%), pre-treatment imaging (RSC: 86.8%; non-RSC: 56.5%) and R0 margins (RSC 57.6%; non-RSC: 20.2%) (p < 0.001). 3y-OS rates were 81.1% (95%CI 78.3-83.6) in AYA in RSC and 82.7% (95%CI 79.4-85.5) in AYA in non-RSC, respectively. Whereas no significant differences in OS was observed in AYAs treated in RSC and in non-RSC, LRFS and PFS were improved in AYAs treated in RSC compared to AYAs treated in non-RSC (Hazard Ratios (HR): 0.58 and 0.83, respectively).

CONCLUSIONS

This study highlights the importance for AYA patients with sarcoma to be managed in national sarcoma reference centers involving multidisciplinary medical teams with paediatric and adult oncologists.

Radical abdomino-pelvic surgery in the management of uterine carcinosarcoma with concomitant para-aortic lymphadenopathy metastasising from anal carcinoma

Uterine carcinosarcomas are aggressive gynaecological cancers comprising less than 5% of uterine malignancies. We present the case of a woman in her 70s with a complicated history of advanced anal carcinoma treated with pelvic radiotherapy and multiple laparotomies, who was referred to gynae-oncology following MRI surveillance imaging showing evidence of endometrial carcinoma and para-aortic lymphadenopathy. Successful surgical excision required multidisciplinary teamwork between gynae-oncology, colorectal and urology surgeons. The patient underwent midline laparotomy, with adhesiolysis, ileum resection and side to side anastomosis, posterior exenteration, left kidney mobilisation and suspension, para-aortic lymph node debulking and left ureteric stent insertion. Significant challenge was posed by the extensive adhesions from previous laparotomies and the debulking of the para-aortic lymph nodes around the renal vessels. This case demonstrates the importance of a multidisciplinary approach in complex pelvic surgery and the vitality of good communication between colleagues in achieving effective patient care.

Racial Disparities in Time to Treatment Persist in the Setting of a Comprehensive Breast Center

BACKGROUND

Racial disparities in breast cancer care have been linked to treatment delays. We explored whether receiving care at a comprehensive breast center could mitigate disparities in time to treatment.

METHODS

Retrospective chart review identified breast cancer patients who underwent surgery from 2012 to 2018 at a comprehensive breast center. Time-to-treatment intervals were compared among self-identified racial and ethnic groups by negative binomial regression models.

RESULTS

Overall, 2094 women met the inclusion criteria: 1242 (59%) White, 262 (13%) Black, 302 (14%) Hispanic, 105 (5%) Asian, and 183 (9%) other race or ethnicity. Black and Hispanic patients more often had Medicaid insurance, higher American Society of Anesthesiologists (ASA) scores, advanced-stage breast cancer, mastectomy, and additional imaging after breast center presentation (p < 0.05). After controlling for other variables, racial or ethnic minority groups had consistently longer intervals to treatment, with Black women experiencing the greatest disparity (incidence rate ratio 1.42). Time from initial comprehensive breast center visit to treatment was also significantly shorter in White patients versus non-White patients (p < 0.0001). Black race, Medicaid insurance/being uninsured, older age, earlier stage, higher ASA score, undergoing mastectomy, having reconstruction, and requiring additional pretreatment work-up were associated with a longer time from initial visit at the comprehensive breast center to treatment on multivariable analysis (p < 0.05).

CONCLUSION

Racial or ethnic minority groups have significant delays in treatment even when receiving care at a comprehensive breast center. Influential factors include insurance delays and necessity of additional pretreatment work-up. Specific policies are needed to address system barriers in treatment access.

A multidisciplinary approach remains the best strategy to improve and strengthen the management of ovarian cancer (Review)

Ovarian cancer represents one of the most aggressive female tumors worldwide. Over the decades, the therapeutic options for the treatment of ovarian cancer have been improved significantly through the advancement of surgical techniques as well as the availability of novel effective drugs able to extend the life expectancy of patients. However, due to its clinical, biological and molecular complexity, ovarian cancer is still considered one of the most difficult tumors to manage. In this context, several studies have highlighted how a multidisciplinary approach to this pathology improves the prognosis and survival of patients with ovarian cancer. On these bases, the aim of the present review is to present recent advantages in the diagnosis, staging and treatment of ovarian cancer highlighting the benefits of a patient‑centered care approach and on the importance of a multidisciplinary team for the management of ovarian cancer.

U.S. News & World Report Ophthalmology Hospital Rankings and Research Productivity

Introduction Despite the wide usage of U.S. News & World Report (U.S. News) rankings of ophthalmology hospitals among the public, residency applicants, and ophthalmologists, there is disagreement in the literature on the role of quality of care, research productivity, and other factors in the ranking system. This study investigated the association of U.S. News ranking of ophthalmology hospitals and objective measures of research productivity.

Methods The 2020 U.S. News “Best Hospitals for Ophthalmology” ranking lists 38 hospitals by reputation score and numerically ranks the top 12 institutions. For our analysis, top 12 hospitals were classified as group A and the remaining 26 as group B. The Clinicaltrials.gov, National Institutes of Health (NIH) Research Portfolio Online Reporting Tools Expenditures and Results (RePORTER), and NIH Research Portfolio Online Reporting Tools (RePORT) were systematically searched for total clinical trials, NIH funding, and the National Eye Institute (NEI) funding for fiscal years 2017, 2018, and 2019. Faculty size and the number of publications by ophthalmology faculty per hospital were recorded from a previous study in 2016.

Results Independent measures of research productivity significantly associated with group A status after multivariate logistic regression analysis were mean faculty Hirsch's index (h-index) over 15 (odds ratio [OR]: 6.13, 95% confidence interval [CI]: [1.14–32.94]) and conducting five or more total clinical trials (OR: 8.77, 95% CI: [1.39–55.16]).

Conclusion This study suggests that the reputation-based U.S. News ranking may serve as a proxy for an ophthalmology department's contribution to research measured by mean faculty h-index and number of clinical trials.

Role of radiation oncology in modern multidisciplinary cancer treatment

Cancer care is moving from a disease‐focused management toward a patient‐centered tailored approach. Multidisciplinary management that aims to define individual, optimal treatment strategies through shared decision making between healthcare professionals and patient is a fundamental aspect of high‐quality cancer care and often includes radiation oncology. Advances in technology and radiobiological research allow to deliver ever more tailored radiation treatments in an ever easier and faster way, thus improving the efficacy, safety, and accessibility of radiation therapy. While these changes are improving quality of cancer care, they are also enormously increasing complexity of decision making, thus challenging the ability to deliver quality affordable cancer care. In this review, we provide an updated outline of the role of radiation oncology in the modern multidisciplinary treatment of cancer. Particularly, we focus on the way some developments in key areas of cancer management are challenging multidisciplinary cancer care in the different clinical settings of early, locally advanced, and metastatic disease, thus highlighting some priority areas of research.

Benefits of Outcomes of the Microscopic Examination of Anastomotic Donuts After Colorectal Resection for Oncological Purposes: A Medical Record-Based Study

Objective 

The objective of the study is to investigate the benefits of pathological assessment of donuts removed during coloanal anastomosis after anterior resection.

Methodology

During three years, 220 patients underwent circular stapled anastomosis. It is a retrospective study with convenient sampling. Involvement of donuts, the involvement of margins, length of donuts, and margins were primarily recorded. Ethical review approval was taken from the Institutional Review Board. Hospital electronic system was used to retrieve the data.

Results

Two hundred and twenty patients underwent circular end to end anastomosis (CEEA) stapled gun anastomosis. All had adenocarcinoma. Most of the patients had T3 disease (n=113). Low anterior resection was the most common procedure followed by anterior resection and sigmoid colectomy, respectively. We performed all rectal cancers anastomosis with a circular stapling gun. On histological analyses among 220 patients, only two patients were found to have a positive distal donut. No proximal donuts were positive. Both patients were also found to have positive distal margins. The mean length of the proximal donut was 1.79±0.45 cm. The mean length of the distal donut was 1.68±0.48 cm. Two distal margins and none of the proximal margins were positive for cancer. The mean length of the proximal margin was 8.69±4.48 cm. The mean length of the distal margin was 4.9±5.98 cm. Both patients had already received six months of pre-operative chemoradiotherapy and were not offered any additional treatment. Both patients were kept on close surveillance.

Conclusion

Routine analyses of the donuts after anterior resection has no impact on the management and outcome of the disease.

Clinical management of adolescents and young adults suffering from sarcoma in the French Rhône-Alpes region: A prospective exhaustive cohort with 10 years follow up

INTRODUCTION

Survival of adolescents and young adults (AYA) with sarcoma is lower than in younger patients. The objective of this study was to describe the regional healthcare circuits, the differences in the management between adult, paediatric and mixed units and to assess the prognostic impact of compliance with clinical practice guidelines (CPGs) on overall survival (OS) and on relapse free survival (RFS).

MATERIALS AND METHODS

Retrospective analysis of the management and long term follow-up of all 13-25 year old patients with a sarcoma diagnosed in the Rhône-Alpes area between 2000 and 2005.

RESULTS

140 patients satisfied inclusion criteria and were selected. The majority of 13-25 year old patients were treated in paediatric units. Joint management resulted in a higher rate of discussion in multidisciplinary tumour board, inclusion in clinical trials, and fertility preservation. Non-compliance with guidelines was observed in 65% of cases. Overall compliance was not reported to correlate to survival. Compliance of radiotherapy with CPG's seemed associated with a better prognosis for OS (HR = 0.20, 95% CI = [0.10-0.40]; p < 0.0001) and RFS (HR = 0.18, 95% CI = [0.09-0.37; p < 0.0001) as well as compliance of surgery for OS (HR = 0.43, 95% CI = [0.23-0.81]; p = 0.01). Multivariate Cox regression analysis revealed other independent predictors of OS like age at diagnosis, stage and histological subtype.

CONCLUSIONS

Management of AYA in joint units seems to improve the quality of care. Compliance of surgery and radiotherapy with CGP's seems to improve survival.

Ultrasound-Guided Core Biopsy of Breast Lesions in a Resource Limited Setting: Initial Experience of a Multidisciplinary Team

Objective

There is increasing tendency to multidisciplinary care of patients with of breast lesions. This study sought to evaluate the initial experience of the diagnostic arm of a new breast program in a resource limited setting.

Materials and Methods

In 2015, we commenced the pilot phase of an IRB-approved breast care protocol. As part of the protocol's diagnostic arm, an ultrasound-guided breast core biopsy training was implemented. Eligible patients were clinically evaluated and underwent CNB using 16G needle under US guidance. The procedure was rated by the participants and histopathological results compared with surgical specimens.

Results

Eighty six participants (18.22%) with 113 palpable breast lesions completed the study. The diagnostic accuracy, sensitivity, and specificity were 94.44%, 92.86%, and 95.83% respectively. Unweighted kappa-coefficient (k) agreement between histopathology of core biopsy and surgically excised specimens, were 0.798 (95% CI of 0.69 - 0.90) and 0.801 (95% CI of 0.71-0.92) for benign and malignant breast lumps respectively. The procedure was well accepted and all the patients were willing to accept a repeat CNB and would recommend it.

Conclusion

Despite the prevailing challenges, co-ordinated team diagnosis is feasible and may result in the modest improvement in the diagnostic accuracy of breast lesions and patient satisfaction.

Testicular cancer: improving outcomes with national quality performance indicators

Testicular cancer is the most common malignancy in young adult men. The prognosis is excellent in limited disease and cure is possible even in advanced disease. Quality performance indicators (QPI) are used in many developed countries as a measure of healthcare performance. We report and discuss the development of a national set of QPIs in Scotland for testicular cancer as a method of gathering demographic data and driving improvement in nationwide testicular cancer outcomes.

The Value and Future Developments of Multidisciplinary Team Cancer Care

Multidisciplinary teams (MDTs) have been recommended as a key part of best cancer care for 25 years. Here, we set out the functions and approaches of MDTs and review their impact. Although the literature is patchy in quality, MDTs contribute to improving cancer care and outcomes. They must be well organized, efficient, and well led; work with sound and timely information; and communicate well within the team and with their patients. Patients need carefully prepared information to help them share in the decision-making process. MDTs will be improved by a series of ongoing innovative developments. Increasing information from molecular pathology will increase the precision of their decisions, although the technologies remain expensive and may not be accessible in all countries for some time. New point-of-care testing technologies will improve the quality and timeliness of testing. Good informatics is essential to deliver the information to patients and the MDT. MDTs should be research active, delivering clinical trials, and this should improve outcomes for all of their patients. Patient engagement and empowerment in MDTs should improve patient satisfaction and outcomes. Patient-reported outcome measures will improve MDTs' insights into their patients' problems and symptoms and can improve patient outcomes.

Interdisciplinary Screening, Diagnosis, Therapy and Follow-up of Breast Cancer. Guideline of the DGGG and the DKG (S3-Level, AWMF Registry Number 032/045OL, December 2017) - Part 1 with Recommendations for the Screening, Diagnosis and Therapy of Breast Cancer

Purpose The aim of this official guideline coordinated and published by the German Society for Gynecology and Obstetrics (DGGG) and the German Cancer Society (DKG) was to optimize the screening, diagnosis, therapy and follow-up care of breast cancer. Methods The process of updating the S3 guideline dating from 2012 was based on the adaptation of identified source guidelines which were combined with reviews of evidence compiled using PICO (Patients/Interventions/Control/Outcome) questions and the results of a systematic search of literature databases and the selection and evaluation of the identified literature. The interdisciplinary working groups took the identified materials as their starting point to develop recommendations and statements which were modified and graded in a structured consensus procedure. Recommendations Part 1 of this short version of the guideline presents recommendations for the screening, diagnosis and follow-up care of breast cancer. The importance of mammography for screening is confirmed in this updated version of the guideline and forms the basis for all screening. In addition to the conventional methods used to diagnose breast cancer, computed tomography (CT) is recommended for staging in women with a higher risk of recurrence. The follow-up concept includes suggested intervals between physical, ultrasound and mammography examinations, additional high-tech diagnostic procedures, and the determination of tumor markers for the evaluation of metastatic disease.

Incidence and Survival Cancer Trends in Children and Adolescents in the Provinces of Florence and Prato (Central Italy), 1985–1997

Aims and background

The incidence of childhood and adolescent cancers has been increasing during the last decades in most Western countries. Improvements in cancer survival rates have also been observed according to the availability of more efficient therapies.

Methods and study design

A total of 518 cancer cases (age, 0–19 years) incident in the period 1985–1997 in the Tuscany Cancer Registry area, corresponding to the Provinces of Florence and Prato (Central Italy), were analyzed. Incidence rates and estimated annual percentage change were computed according to sex, 5-year age groups and diagnostic groups of the International Classification for Childhood Cancer. All patients were actively followed at 31.12.1998, and 5-year survival rates were computed for cases diagnosed in 1985–1990 and 1991–1997.

Results

Overall age-standardized incidence rates were 186.7/106 for males and 175.4 for females. In 1991–1997, standardized incident rates were 50.8 for leukemias, 44.6 for lymphomas, and 34.3 for CNS tumors. There was a marked increasing trend for lymphomas that grew at a yearly rate of +12.1% and less evident increasing tendency for leukemias, CNS tumors and carcinomas. The overall survival rate was 88% at one year, 78% at 3 years, and 74% at 5 years. A slight improving tendency in survival was evident over time.

Conclusions

The study pointed out that in the examined area, during 1985–1997, there was a significant increasing incidence trend for lymphomas. Survival rates were as high as in other Western countries – evidence of the high level of diagnostic and treatment services in the area.

Interpreting Survival Differences and Trends

Since 1990 a concerted action between European population-based cancer registries (the EUROCARE project) has been carried out with the aims of establishing whether there are differences in cancer patient survival in Europe, and the reasons for such differences. Survival differences actually exist for cancer sites for which the stage of disease at diagnosis is the major prognostic factor (such as breast, stomach and colon cancer). However, for most cancer sites, survival increases over time and the survival rates of different countries tend to converge towards higher values. Interpreting survival differences and trends is not an easy task. Longer survival may be achieved by postponing death through better treatment or by anticipating diagnosis. However, an earlier diagnosis may or may not make a treatment more effective in postponing death. The computation of stage-specific or stage-adjusted survival is not sufficient for interpretation of survival differences, because staging procedures change over time and may vary in different hospitals and countries. In addition to an early diagnosis and more effective treatment, a number of factors may bias survival estimates. They may be classified into factors that can be controlled in the analysis (at least partially), such as mortality from other causes, demographic factors, epoch of diagnosis, different statistical methodology, and factors depending on the validity of cancer registry data, such as definition of the illness, exhaustiveness and quality of registration, completeness of follow-up, definition of the date of diagnosis, and definition of disease stage including the diagnostic procedure used to establish stage. To help disentangle the effects of early diagnosis and better treatment, several statistical approaches are being developed: multivariate analysis on relative survival data, new modeling analysis to separately estimate the proportion of cured patients and the length of survival for those patients destined to die, and the standardized collection of information on stage at diagnosis and staging procedures.

Survival of Childhood Cancer Patients in Italy, 1978–1989

In the framework of the ITACARE project, a cooperative investigation conducted on the data from the Italian population-based cancer registries, survival of patients with childhood malignant neoplasms was studied. The study included 1,768 cases diagnosed at age 0–14 plus 29 osteosarcoma cases diagnosed at age 15–19. Cases were collected over the period 1978–1989, or more limited periods for some participating registries. A total of 1,138 cases were from the Childhood Cancer Registry of Piedmont and 659 from the registries operating in the provinces of Varese, Parma, Modena, Forlì and Ravenna, Florence, Latina, Ragusa and in the cities of Genova and Torino (the last contributed only for bone neoplasm diagnosed at age 15–19). Overall 5-year survival was 54% for malignancies diagnosed in 1978–1981, 60% for the period 1982–1985, and 69% for the period 1986–1989. The range among registries of 5-year survival for cases diagnosed in 1986–1989 was 55–78%. Most diagnostic categories presented an improved prognosis for the cases diagnosed more recently. For cases diagnosed in 1986–1989, 5-year survival was: 74% for acute lymphatic leukaemia, 40% for acute non-lymphatic leukaemia, 65% for central nervous system neoplasms (76% for astrocytoma, 75% for ependymoma and 85% for medulloblastoma), 66% for osteosarcoma, 55% for Ewing's sarcoma, 87% for Hodgkin's disease, 64% for non-Hodgkin's lymphoma, 74% for rhabdomyosarcoma, 64% for neuroblastoma, 78% for nephroblastoma and 100% for retinoblastoma. Italian survival was similar to that observed in other population-based surveys in the UK and USA.

Extreme hepatic resections for the treatment of advanced hepatoblastoma: Are planned close margins an acceptable approach?

BACKGROUND

Orthotopic liver transplantation (OLT) is considered the standard for children with hepatoblastoma (HB) in whom complete surgical resection is not possible. However, OLT is not always available or feasible.

OBJECTIVE

To describe the outcome of children with HB who were initially deemed unresectable and underwent complex hepatectomy with planned close margins, and ultimately avoided OLT.

METHODS

Demographic data, surgical and pathologic details, and survival information were collected from children treated for HB between January 2010 to December 2015.

RESULTS

Among six children (median age 12 months (3-41 months)), PRETEXT classification was III (n = 2), III/IV (n = 1), and IV (n = 3). Patients received a median of six cycles (range 4-7) of platinum-based induction chemotherapy; five received doxorubicin. Experienced pediatric surgeons performed extended right and left hepatectomy in five and one patients, respectively, with assistance of an experienced liver transplant surgeon (n = 4). Microscopic margins were positive (n = 2) and negative but close (n = 4; 2-5 mm). Two patients required vascular reconstruction of the vena cava. At median follow-up of 3.3 years (1.7-4.6 years), there was no evidence of local recurrence. One patient had recurrence of pulmonary disease 3 months after surgery.

CONCLUSIONS

Patients with advanced HB treated with complex surgical resections with positive or close negative margins had good outcomes without OLT. We suggest that planned positive or close microscopic margins in highly selected HB patients may spare the morbidity of OLT and offer an alternative for those ineligible for OLT. Our experience illustrates the importance of a multidisciplinary team specialized in the management of liver tumors.

Predictors for papillary thyroid cancer persistence and recurrence: a retrospective analysis with a 10-year follow-up cohort study

OBJECTIVE

We aimed to determine outcome predictors of papillary thyroid cancer (PTC) persistence and recurrence, separately.

CONTEXT

The factors contributing to either persistence or recurrence of PTC are poorly defined, as both outcomes are usually evaluated together.

DESIGN AND PATIENTS

In this 10-year follow-up cohort study, 190 PTC patients were evaluated (18-85 years old; registered from 1 January 1990 to31 December 1999 at a Brazilian Cancer Care referral Hospital). After initial surgery, we examined persistence (disease detected up to 1 year), recurrence (disease detected after 1 year) and PTC-free status (disease absence during follow-up).

MEASUREMENTS

Outcome predictors were modelled using multinomial logit regression analysis.

RESULTS

The univariate analysis showed that persistence and recurrence were significantly associated with lymph node metastasis (OR = 12·33; OR = 2·84, respectively), local aggressiveness (OR = 5·22; OR = 3·35) and extrathyroidal extension (OR = 5·07; OR = 7·11). Persistence was associated with male sex (OR = 3·49), age above 45 years old at diagnosis (OR = 1·03), macroscopic lymph node metastasis (OR = 5·85), local aggressiveness (OR = 5·22), each 1-cm tumour size increase (OR = 1·34), a cancer care referral hospital as the place of initial surgery (OR = 2·3), thyroidectomy or near total thyroidectomy(OR = 3·03) and neck dissection (OR = 3·19). Recurrence was associated with the time of radioactive iodine ((131) I) therapy (OR = 3·71). After data modelling, persistence was associated with macroscopic lymph node metastasis (OR = 6·17), 1-cm increases in tumour size (OR = 1·30) and thyroidectomy or near total thyroidectomy (OR = 3·82), while recurrence was associated with surgery at referral hospital (OR = 3·79).

CONCLUSIONS

The best predictors of persistence were tumour size and macroscopic lymph node metastasis; when the initial surgery is of quality, the recurrence depends more on tumour's biology aspects.

Influence of hospital type on survival in stage IV colorectal cancer

PURPOSE

Hospital factors along with various patient and surgeon factors are considered to affect the prognosis of colorectal cancer. Hospital volume is well known, but little is known regarding other hospital factors.

METHODS

We reviewed data on 853 patients with stage IV colorectal cancer who underwent elective palliative primary tumor resection between January 2006 and December 2007. To detect the hospital factors that could influence the prognosis of incurable colorectal cancer, the relationships between patient/hospital factors and overall survival were analyzed. Among hospital factors, hospital type (Group A: university hospital or cancer center; Group B: community hospital), hospital volume, and number of colorectal surgeons were examined.

RESULTS

In univariate analysis, Group A hospitals showed significantly better prognosis than Group B hospitals (p = 0.034), while hospital volume and number of colorectal surgeons were not associated with overall survival. After adjustment for patient factors in multivariate analysis, hospital type was significantly associated with overall survival (hazard ratio: 1.31; 95 % confidence interval: 1.05-1.63; p = 0.016). However, there was no significant difference in short-term outcomes between hospital types.

CONCLUSIONS

Hospital type was identified as a hospital factor that possibly affects the prognosis of stage IV colorectal cancer patients.

Gynäkologische Malignome bei Patientinnen mit rheumatisch‑entzündlichen Systemerkrankungen

Das Risiko für gynäkologische Tumoren bei rheumatisch-entzündlichen Systemerkrankungen scheint nur in Bezug auf das Zervixkarzinom v. a. bei systemischem Lupus erythematodes erhöht zu sein. Studien weisen auf die Bedeutung des Immunsystems für die Tumorkontrolle bei gynäkologischen Tumoren hin. Bislang konnte aber nur für das Zervixkarzinom ein ungünstiger Einfluss einer medikamentösen Immunsuppression bei rheumatologischen Patientinnen gezeigt werden. Biologika wirken sich bei dieser Entität dagegen nicht eindeutig tumorfördernd aus. Die Datenlage bei dieser Fragestellung ist allerdings begrenzt. Generelle Screeningempfehlungen existieren für das Mammakarzinom und das Zervixkarzinom. Empfehlungen zur Tumornachsorge werden dargestellt. Aufgrund der unzureichenden Datenlage empfiehlt sich zumindest in den ersten 5 Jahren nach kurativer onkologischer Therapie eine sehr strenge Indikationsstellung zum Einsatz von Immunsuppressiva und Biologika auch bei gynäkologischen Tumoren. Im Falle des Mammakarzinoms wird sogar die Beachtung eines längeren Intervalls diskutiert.

An Association of Cancer Physicians' strategy for improving services and outcomes for cancer patients

The Association of Cancer Physicians in the United Kingdom has developed a strategy to improve outcomes for cancer patients and identified the goals and commitments of the Association and its members.

Do Multidisciplinary Team (MDT) processes influence survival in patients with colorectal cancer? A population-based experience

Background

MDT (multidisciplinary team) meetings are considered an essential component of care for patients with cancer. However there is remarkably little direct evidence that such meetings improve outcomes. We assessed whether or not MDT (multidisciplinary team) processes influenced survival in a cohort of patients with colorectal cancer.

Methods

Observational study of a population-based cohort of 586 consecutive patients with colorectal cancer diagnosed in Tayside (Scotland) during 2006 and 2007.

Results

Recommendations from MDT meetings were implemented in 411/586 (70.1 %) of patients, the MDT+ group. The remaining175/586 (29.9 %) were either never discussed at an MDT, or recommendations were not implemented, MDT- group. The 5-year cause-specific survival (CSS) rates were 63.1 % (MDT+) and 48.2 % (MDT-), p < 0.0001. In analysis confined to patients who survived >6 weeks after diagnosis, the rates were 63.2 % (MDT+) and 57.7 % (MDT-), p = 0.064. The adjusted hazard rate (HR) for death from colorectal cancer was 0.73 (0.53 to 1.00, p = 0.047) in the MDT+ group compared to the MDT- group, in patients surviving >6 weeks the adjusted HR was 1.00 (0.70 to 1.42, p = 0.987). Any benefit from the MDT process was largely confined to patients with advanced disease: adjusted HR _(early) 1.32 (0.69 to 2.49, p = 0.401); adjusted HR_(advanced) 0.65 (0.45 to 0.96, p = 0.031).

Conclusions

Adequate MDT processes are associated with improved survival for patients with colorectal cancer. However, some of this effect may be more apparent than real – simply reflecting selection bias. The MDT process predominantly benefits the 40 % of patients who present with advanced disease and conveys little demonstrable advantage to patients with early tumours. These results call into question the current belief that all new patients with colorectal cancer should be discussed at an MDT meeting.

[Consensus statement for accreditation of multidisciplinary thyroid cancer units]

Thyroid cancer is the leading endocrine system tumor. Great advances have recently been made in understanding of the origin of these tumors and the molecular biology that makes them grow and proliferate, which have been associated to improvements in diagnostic procedures and increased availability of effective local and systemic treatments. All of the above makes thyroid cancer a paradigm of how different specialties should work together to achieve the greatest benefit for the patients. Coordination of all the procedures and patient flows should continue throughout diagnosis, treatment, and follow-up, and is essential for further optimization of resources and time. This manuscript was prepared at the request of the Working Group on Thyroid Cancer of the Spanish Society of Endocrinology and Nutrition, and is aimed to provide a consensus document on the definition, composition, requirements, structure, and operation of a multidisciplinary team for the comprehensive care of patients with thyroid cancer. For this purpose, we have included contributions by several professionals from different specialties with experience in thyroid cancer treatment at centers where multidisciplinary teams have been working for years, with the aim of developing a practical consensus applicable in clinical practice.

Regional variation in breast cancer treatment in the Netherlands and the role of external peer review: a cohort study comprising 63,516 women

BACKGROUND

Treatment variation is an important issue in health care provision. An external peer review programme for multidisciplinary cancer care was introduced in 1994 in the Netherlands to improve the multidisciplinary organisation of cancer care in hospitals.So far the clinical impact of external quality assessment programmes such as external peer review and accreditation remains unclear. Our objective was to examine the degree of variation in treatment patterns and the possible effect of external peer review for multidisciplinary cancer care for breast cancer patients.

METHODS

Patients with breast cancer were included from 23 hospitals from two 'intervention regions' with the longest experience with the programme and 7 hospitals that never participated (control group). Data on tumour and treatment characteristics were retrieved from the Netherlands Cancer Registry. Treatment modalities investigated were: the completeness of breast conserving therapy, introduction of the sentinel node biopsy, radiotherapy after breast conserving surgery for ductal carcinoma in situ (DCIS), adjuvant radiotherapy for locally advanced breast cancer (T3/M0 or any T,N2-3/M0), adjuvant chemotherapy for early stage breast cancer (T1-2/N+/M0) and neo-adjuvant chemotherapy for T4/M0 breast cancer. Hospitals from the two intervention regions were dichotomised based on their implementation proportion (IP) of recommendations from the final reports of each peer review (high IP vs. low IP). This was regarded as a measure of how well a hospital participated in the programme.

RESULTS

63,516 female breast cancer patients were included (1990-2010). Variation in treatment patterns was observed between the intervention regions and control group. Multidisciplinary treatment patterns were not consistently better for patients from hospitals with a high IP.

CONCLUSIONS

There is no relationship between the external peer review programme for multidisciplinary cancer care and multidisciplinary treatment patterns for breast cancer patients. Regional factors seem to exert a stronger effect on treatment patterns than hospital participation in external peer review.

Geographical Factors Affecting the Admission of Teenagers and Young Adults to Age-Specialist Inpatient Cancer Care in England

Purpose: Little is known about the factors that influence the place of inpatient care for teenage and young adult (TYA) cancer patients. Recent guidelines have recommended centralization of care for this group to a small number of specialized centers. This study aimed to investigate the influence of geography and travel times on the likelihood of admission to an age-specialist center in England during cancer treatment for patients aged 15-24 at the time of diagnosis. Methods: Data for 6788 patients aged 15-24, diagnosed between 2001 and 2006 and treated as an inpatient in England between 2001 and 2009, were obtained from the National Cancer Data Repository. Eight TYA age-specialist centers were identified in England during this time period; road travel times to these centers were calculated using ArcGIS Network Analyst. Factors thought to affect the likelihood of admission, such as diagnostic group, gender, and age at diagnosis were modeled using logistic regression. Results: Overall, 66.9% of patients never received inpatient treatment at a TYA age-specialist center during the course of their treatment. Increasing travel time significantly reduced the likelihood of admission to a TYA age-specialist center after adjustment for case mix factors. Conclusion: Many TYA patients received little or no inpatient treatment at a TYA age-specialist center during their treatment. The variation between diagnostic groups suggests that factors other than distance to the closest center are affecting the likelihood of admission and demonstrates the potential need to consider improvements to the structured referral practice for this unique group of patients.

Timing of radiotherapy following breast-conserving surgery: outcome of 1393 patients at a single institution

BACKGROUND

The role of postoperative radiotherapy in breast-conserving therapy is undisputed. However, optimal timing of adjuvant radiotherapy is an issue of ongoing debate. This retrospective clinical cohort study was performed to investigate the impact of a delay in surgery-radiotherapy intervals on local control and overall survival.

PATIENTS AND METHODS

Data from an unselected cohort of 1393 patients treated at a single institution over a 17-year period (1990-2006) were analyzed. Patients were assigned to two groups (CT+/CT-) according to chemotherapy status. A delay in the initiation of radiotherapy was defined as > 7 weeks (CT- group) and > 24 weeks (CT+ group).

RESULTS

The 10-year regional recurrence-free survival for the CT- and CT+ groups were 95.6 and 86.0 %, respectively. A significant increase in the median surgery-radiotherapy interval was observed over time (CT- patients: median of 5 weeks in 1990-1992 to a median of 6 weeks in 2005-2006; CT+ patients: median of 5 weeks in 1990-1992 to a median of 21 weeks in 2005-2006). There was no association between a delay in radiotherapy and an increased local recurrence rate (CT- group: p = 0.990 for intervals 0-6 weeks vs. ≥ 7 weeks; CT+ group: p = 0.644 for intervals 0-15 weeks vs. ≥ 24 weeks) or decreased overall survival (CT- group: p = 0.386 for intervals 0-6 weeks vs. ≥ 7 weeks; CT+ group: p = 0.305 for intervals 0-15 weeks vs. ≥ 24 weeks).

CONCLUSION

In the present cohort, a delay of radiotherapy was not associated with decreased local control or overall survival in the two groups (CT-/CT+). However, in the absence of randomized evidence, delays in the initiation of radiotherapy should be avoided.

Benefits of multidisciplinary teamwork in the management of breast cancer

The widespread introduction of multidisciplinary team (MDT)-work for breast cancer management has in part evolved due to the increasing complexity of diagnostic and treatment decision-making. An MDT approach aims to bring together the range of specialists required to discuss and agree treatment recommendations and ongoing management for individual patients. MDTs are resource-intensive yet we lack strong (randomized controlled trial) evidence of their effectiveness. Clinical consensus is generally favorable on the benefits of effective specialist MDT-work. Many studies have shown the benefits of receiving treatment from a specialist center, and evidence continues to accrue from comparative studies of clinical benefits of an MDT approach, including improved survival. Patients’ views of the MDT model of decision-making (and in particular its impact on involvement in decisions about their care) have been under-researched. Barriers to effective teamwork and poor decision-making include excessive caseload, low attendance at meetings, lack of leadership, poor communication, role ambiguity, and failure to consider patients’ holistic needs. Breast cancer nurses have a key role in relation to assessing holistic needs, and their specialist contribution has also been associated with improved patient experience and quality of life. This paper examines the evidence for the benefits of MDT-work, in particular for breast cancer. Evidence is considered within a context of growing cancer incidence at a time of increased financial restraint, and it may now be important to reevaluate the structure and models of MDT-work to ensure that MDTs are an efficient use of resources.

The varying role of the GP in the pathway between colonoscopy and surgery for colorectal cancer: a retrospective cohort study

OBJECTIVES

To describe general practitioner (GP) involvement in the treatment referral pathway for colorectal cancer (CRC) patients.

DESIGN

A retrospective cohort analysis of linked data.

SETTING

A population-based sample of CRC patients diagnosed from August 2004 to December 2007 in New South Wales, Australia, using the 45 and Up Study, cancer registry diagnosis records, inpatient hospital records and Medicare claims records.

PARTICIPANTS

407 CRC patients who had a colonoscopy followed by surgery.

PRIMARY OUTCOME MEASURES

Patterns of GP consultations between colonoscopy and surgery (ie, between diagnosis and treatment). We investigated whether consulting a GP presurgery was associated with time to surgery, postsurgical GP consultations or rectal cancer cases having surgery in a centre with radiotherapy facilities.

RESULTS

Of the 407 patients, 43% (n=175) had at least one GP consultation between colonoscopy and surgery. The median time from colonoscopy to surgery was 27 days for those with an intervening GP consultation and 15 days for those without the consultation. 55% (n=223) had a GP consultation up to 30 days postsurgery; it was more common in cases of patients who consulted a GP presurgery than for those who did not (65% and 47%, respectively, adjusted OR 2.71, 95% CI 1.50 to 4.89, p=0.001). Of the 142 rectal cancer cases, 23% (n=33) had their surgery in a centre with radiotherapy facilities, with no difference between those who did and did not consult a GP presurgery (21% and 25% respectively, adjusted OR 0.84, 95% CI 0.27 to 2.63, p=0.76).

CONCLUSIONS

Consulting a GP between colonoscopy and surgery was associated with a longer interval between diagnosis and treatment, and with further GP consultations postsurgery, but for rectal cancer cases it was not associated with treatment in a centre with radiotherapy facilities. GPs might require a more defined and systematic approach to CRC management.

Effects of multidisciplinary team working on breast cancer survival: retrospective, comparative, interventional cohort study of 13 722 women

OBJECTIVES

To describe the effect of multidisciplinary care on survival in women treated for breast cancer.

DESIGN

Retrospective, comparative, non-randomised, interventional cohort study.

SETTING

NHS hospitals, health boards in the west of Scotland, UK.

PARTICIPANTS

14,358 patients diagnosed with symptomatic invasive breast cancer between 1990 and 2000, residing in health board areas in the west of Scotland. 13,722 (95.6%) patients were eligible (excluding 16 diagnoses of inflammatory cancers and 620 diagnoses of breast cancer at death).

INTERVENTION

In 1995, multidisciplinary team working was introduced in hospitals throughout one health board area (Greater Glasgow; intervention area), but not in other health board areas in the west of Scotland (non-intervention area).

MAIN OUTCOME MEASURES

Breast cancer specific mortality and all cause mortality.

RESULTS

Before the introduction of multidisciplinary care (analysed time period January 1990 to September 1995), breast cancer mortality was 11% higher in the intervention area than in the non-intervention area (hazard ratio adjusted for year of incidence, age at diagnosis, and deprivation, 1.11; 95% confidence interval 1.00 to 1.20). After multidisciplinary care was introduced (time period October 1995 to December 2000), breast cancer mortality was 18% lower in the intervention area than in the non-intervention area (0.82, 0.74 to 0.91). All cause mortality did not differ significantly between populations in the earlier period, but was 11% lower in the intervention area than in the non-interventional area in the later period (0.89, 0.82 to 0.97). Interrupted time series analyses showed a significant improvement in breast cancer survival in the intervention area in 1996, compared with the expected survival in the same year had the pre-intervention trend continued (P=0.004). This improvement was maintained after the intervention was introduced.

CONCLUSION

Introduction of multidisciplinary care was associated with improved survival and reduced variation in survival among hospitals. Further analysis of clinical audit data for multidisciplinary care could identify which aspects of care are most associated with survival benefits.

Processes and outcomes of care for soft tissue sarcoma of the extremities

Purpose: A population-based cohort study of soft tissue sarcoma of the extremities (STSE) in Ontario, Canada was conducted using linked administrative databases.

Methods and materials: Electronic administrative databases were linked from the Ontario Cancer Registry, the Canadian Institute for Health Information, and Radiation Oncology Research Unit database of radiation therapy (RT) records.

Results: The definitive surgery was amputation for 6.0%, resection for 60.9%, biopsy for 7.5%; the remainder had no surgical record. Adjuvant RT was administered to 40.2% of cases. Among cases initially treated by surgical resection, 2.0% later underwent amputation and 9.5% underwent further resection during follow-up. The adjusted odds ratio (OR) for amputation as definitive surgery was 2.3 (1.19, 4.45) in eastern Ontario relative to Toronto. The likelihood of adjuvant RT among those not registered at a cancer centre within 3 months of diagnosis was decreased (OR = 0.20 (95% CI (0.13, 0.30)) relative to those registered. The adjusted relative risk of amputation at any time following diagnosis was 3.48 (95% CI (1.63, 7.46)) among cases not attending a cancer centre. The adjusted relative risk of death was 1.4; 95% CI (1.1, 1.7) among those not attending a cancer centre.

Conclusions: Cases not seen at a multidisciplinary cancer centre within 3 months following diagnosis of STSE have an increased relative risk for amputation at any time, and for death due to any cause. Many hypotheses for further study are suggested by the results of this analysis.

Role of comprehensive cancer centres during economic and disease transition: National Cancer Centre, Singapore--a case study

In 1999, Singapore created a comprehensive cancer centre because of the rising occurrence of cancer in the country. Although Singapore is different from many developing countries because of its small geographical size and its well-endowed economy, it has issues that are common to any country or community wanting to start such centres. We present our experience of developing a comprehensive cancer centre. We located the cancer centre strategically adjacent to Singapore's largest hospital. Clinics were designed to provide multidisciplinary care, and site-specific radiation, medical, and surgical oncologists could consult with patients on the same day and at the multidisciplinary outpatient clinics. We developed a large research team and ensured that tumour specimens were carefully obtained and annotated in our tissue repository. Furthermore, we are building up a robust cancer informatics system as well as a pipeline of specialists with local training and overseas stints at other top cancer centres.

The impact of the Calman-Hine report on the processes and outcomes of care for Yorkshire's breast cancer patients

BACKGROUND

The 1995 Calman-Hine plan outlined radical reform of the UK's cancer services with the aim of improving outcomes and reducing inequalities in National Health Service cancer care. Its main recommendation was to concentrate care into the hands of site-specialist multidisciplinary teams. This study aimed to determine whether these teams improved processes and outcomes of care for breast cancer patients.

PATIENTS AND METHODS

All patients diagnosed and treated with breast cancer in the Yorkshire region of the UK from 1995 to 2000 were identified within the Northern and Yorkshire Cancer Registry and Information Service database. Changes in the use of breast-conserving surgery, adjuvant radiotherapy following breast-conserving surgery and 5-year survival were assessed among these patients in relation to their managing breast cancer team's degree of adherence to the manual of cancer service standards (which outlines the specification of the 'ideal' breast cancer team) and the extent of site specialisation of each team's surgeons.

RESULTS

Variation was observed in the extent to which the breast cancer teams in Yorkshire had conformed to the Calman-Hine recommendations. Increases in adherence to the recommendations in the manual of cancer service standards were associated with a reduction in the use of breast-conserving surgery [odds ratio (OR) = 0.83, 95% confidence interval (CI) = 0.70-0.98, P < 0.01]. Increases in both surgical specialisation (OR = 1.23, 95% CI = 1.00-1.55, P = 0.06) and adherence to the manual of cancer service standards (OR = 1.22, 95% CI = 0.97-1.52, P = 0.05) were associated with the increased use of radiotherapy following breast-conserving surgery. There was a trend towards improved 5-year survival (hazard ratio = 0.93, 95% CI = 0.86-1.01, P = 0.10) in relation to increasing surgical site specialisation. All these effects were present after adjustment for the casemix factors of age, stage of disease, socio-economic background and year of diagnosis.

CONCLUSIONS

The extent of implementation of the Calman-Hine report has been variable and, on the basis of limited clinical and organisational information available, its recommendations appear to be associated with improvements in processes and outcomes of care for breast cancer patients.

Patterns of survival in multiple myeloma: a population-based study of patients diagnosed in Sweden from 1973 to 2003

PURPOSE

To define patterns of survival among all multiple myeloma (MM) patients diagnosed in Sweden during a 30-year period.

PATIENTS AND METHODS

A total of 14,381 MM patients (7,643 males; 6,738 females) were diagnosed in Sweden from 1973 to 2003 (median age, 69.9 years; range 19 to 101 years). Patients were categorized into six age categories and four calendar periods (1973 to 1979, 1980 to 1986, 1987 to 1993, and 1994 to 2003). We computed relative survival ratios (RSRs) as measures of patient survival.

RESULTS

One-year survival improved (P < .001) over time in all age groups and RSRs were 0.73, 0.78, 0.80, and 0.82 for the four calendar periods; however, improvement in 5-year (P < .001) and 10-year (P < .001) RSR was restricted to patients younger than 70 years and younger than 60 years, respectively. For the first time, in analyses restricted to MM patients diagnosed at age younger than 60 years, we found a 29% (P < .001) reduced 10-year mortality in the last calendar period (1994 to 2003) compared with the preceding calendar period (1987 to 1993). Females with MM had a 3% (P = .024) lower excess mortality than males.

CONCLUSION

One-year MM survival has increased for all age groups during the last decades; 5-year and 10-year MM survival has increased in younger patients (younger than 60 to 70 years). High-dose melphalan with subsequent autologous stem-cell transplantation, thalidomide, and a continuous improvement in supportive care measures are probably the most important factors contributing to this finding. New effective agents with a more favorable toxicity profile are needed to improve survival further, particularly in the elderly.

Influence of provider and practice characteristics on melanoma care

BACKGROUND

Melanoma care is becoming increasingly multidisciplinary, requiring coordination of many types of providers. The purpose of this study is to describe the structure of melanoma care in North Carolina by examining services provided by different providers and the overall coordination of care.

METHODS

Self-administered surveys were developed to collect demographic and practice information, assess patient volume and services provided, and explore referral patterns. Surveys were administered to all dermatologists and a subset of surgeons practicing in North Carolina.

RESULTS

The response rate was 60% (263/438). Melanoma patient volume, referral patterns, use of nodal staging, and access to clinical trials were each related to provider characteristics, specialty, affiliations with cancer care organizations, and practice setting.

CONCLUSIONS

Many types of providers contribute significantly to the care of melanoma patients. Coordination between providers is variable. This study provides indirect evidence that multidisciplinary melanoma programs increase patient access to comprehensive melanoma care.
