Background
Numerous studies have examined prognostic factors for survival of breast cancer patients, but relatively few have dealt specifically with 10+-year survivors.
Methods
A review of the PubMed ...database from 1995 to 2006 was undertaken with the following inclusion criteria: median/mean follow-up time at least 10 years; overall survival and/or disease-specific survival known; and relative risk and statistical probability values reported. In addition, we used data from the long-standing Eindhoven Cancer Registry to illustrate survival probability as indicated by various prognostic factors.
Results
10-year breast cancer survivors showed 90% 5-year relative survival. Tumor size, nodal status and grade remained the most important prognostic factors for long-term survival, although their role decreased over time. Most studies agreed on the long-term prognostic values of MI (mitotic index), LVI (lymphovascular invasion), Her2-positivity, gene profiling and comorbidity for either all or a subgroup of breast cancer patients (node-positive or negative). The roles of age, socioeconomic status, histological type, BRCA and p53 mutation were mixed, often decreasing after correction for stronger prognosticators, thus limiting their clinical value. Local and regional recurrence, metastases and second cancer may substantially impair long-term survival. Healthy lifestyle was consistently related to lower overall mortality.
Conclusions
Effects of traditional prognostic factors persist in the long term and more recent factors need further follow-up. The prognosis for breast cancer patients who have survived at least 10 years is favourable and increases over time. Improved long-term survival can be achieved by earlier detection, more effective modern therapy and healthier lifestyle.
Abstract Introduction We present a comprehensive overview of most recent European trends in population-based incidence of, mortality from and relative survival for patients with cancer since the mid ...1990s. Methods Data on incidence, mortality and 5-year relative survival from the mid 1990s to early 2000 for the cancers of the oral cavity and pharynx, oesophagus, stomach, colorectum, pancreas, larynx, lung, skin melanoma, breast, cervix, corpus uteri, ovary, prostate, testis, kidney, bladder, and Hodgkin’s disease were obtained from cancer registries from 21 European countries. Estimated annual percentages change in incidence and mortality were calculated. Survival trends were analyzed by calculating the relative difference in 5-year relative survival between 1990–1994 and 2000–2002 using data from EUROCARE-3 and -4. Results Trends in incidence were generally favorable in the more prosperous countries from Northern and Western Europe, except for obesity related cancers. Whereas incidence of and mortality from tobacco-related cancers decreased for males in Northern, Western and Southern Europe, they increased for both sexes in Central Europe and for females nearly everywhere in Europe. Survival rates generally improved, mostly due to better access to specialized diagnostics, staging and treatment. Marked effects of organised or opportunistic screening became visible for breast, prostate and melanoma in the wealthier countries. Mortality trends were generally favourable, except for smoking related cancers. Conclusion Cancer prevention and management in Europe is moving in the right direction. Survival increased and mortality decreased through the combination of earlier detection, better access to care and improved treatment. Still, cancer prevention efforts have much to attain, especially in the domain of female smoking prevalence and the emerging obesity epidemic.
When cancer survivors wish to receive accurate information on their current prognosis during follow-up, conditional 5-year relative survival may be most suitable. We have estimated conditional 5-year ...relative survival for 13 cancers using a large European database-European Network for Indicators on Cancer (EUNICE)-of 10 dedicated long-standing cancer registries across Europe.
Patients age 15 years and older diagnosed between 1985 and 2004 were included. Conditional 5-year relative survival for each age group was computed for every additional year survived up to 10 years. Period analysis with follow-up period 2000 to 2004 was used.
All patients with cutaneous melanoma or colorectal, endometrial, or testis cancer and younger patients with stomach, glottis, cervix, ovary, or thyroid cancer or non-Hodgkin's lymphoma exhibited hardly any excess mortality (conditional 5-year relative survival > 95%) given that they were alive at a defined time point within 10 years of initial diagnosis. However, patients with supraglottis, lung, breast, and kidney cancer, as well as older patients with most cancers exhibited substantial excess mortality (conditional 5-year relative survival < 90%). Initial differences in relative survival at diagnosis between age groups largely disappeared with time since initial diagnosis for melanoma, or stomach, colorectal, corpus uteri, or testicular cancer but persisted for patients diagnosed with other tumors. Differences between stage groups became smaller over time or disappeared.
Conditional relative survival shows clinically relevant variations according to time since diagnosis, type of cancer, and age, and can help serve as a guide for cancer survivors in planning for their future and for doctors in planning schedules for surveillance.
The aim of our study was to provide population‐based data on incidence and prognosis of synchronous peritoneal carcinomatosis and to evaluate predictors for its development. Diagnosed in 1995–2008, ...18,738 cases of primary colorectal cancer were included. Predictors of peritoneal carcinomatosis were analysed by multivariable logistic regression analysis. Median survival in months was calculated by site of metastasis. In the study period, 904 patients were diagnosed with synchronous peritoneal carcinomatosis (4.8% of total, constituting 24% of patients presenting with M1 disease). The risk of peritoneal carcinomatosis was increased in case of advanced T stage T4 vs. T1,2: odds ratio (OR) 4.7, confidence limits 4.0–5.6), advanced N stage N0 vs. N1,2: OR 0.2 (0.1–0.2), poor differentiation grade OR 2.1 (1.8–2.5), younger age <60 years vs. 70–79 years: OR 1.4 (1.1–1.7), mucinous adenocarcinoma OR 2.0 (1.6–2.4) and right‐sided localisation of primary tumour left vs. right: OR 0.6 (0.5–0.7). Median survival of patients with peritoneum as single site of metastasis remained dismal 1995–2001: 7 (6–9) months; 2002–2008: 8 (6–11) months, contrasting the improvement among patients with liver metastases 1995–2001: 8 (7–9) months; 2002–2008: 12 (11–14) months. To conclude, synchronous peritoneal metastases from colorectal cancer are more frequent among younger patients and among patients with advanced T stage, mucinous adenocarcinoma, right‐sided tumours and tumours that are poorly differentiated. The prognosis of synchronous peritoneal carcinomatosis remains poor with a median survival of 8 months and even worse if concomitant metastases in other organs are present.
Basal cell carcinoma (BCC) incidence rates are increasing. From 1973 to 2009, data on all first histologically confirmed BCCs were gained from the Eindhoven Cancer Registry to estimate trends in ...patient-based BCC incidence rates by sex, age group, and site in the southeast Netherlands. Trends in European age-standardized rates and age- and site-specific incidence rates were assessed by calculating the estimated annual percentage change (EAPC). Between 1973 and 2009, the European standardized rate quadrupled from 40 to 165 per 100,000 person-years for men and from 34 to 157 for women, significantly increasing since 1973 in both sexes, but accelerating from 2002 until 2009 with an EAPC of 6.8% (95% confidence interval (CI), 5.3–8.3) for men and 7.9% (95% CI, 6.2–9.7) for women. Women below the age of 40 years exhibited a constant linear increase of 6.3% since 1973. The head and neck region was most often affected in both sexes, but the steepest increase was seen for the trunk (EAPC men 13%, women 15%). In the absence of reliable tumor-based rates, these alarming patient-based rates are probably an interesting indicator for the impact of more intensive UV exposure in a prosperous European population.
We assessed the epidemiologic progress against childhood and adolescent acute lymphoblastic leukaemia (ALL) in the Netherlands over a 26 year period. ALL patients <18 years were selected from the ...Netherlands Cancer Registry and the Dutch Childhood Oncology Group. Trend analyses were performed over time and by age group and ALL subtype. Between 1990 and 2015, 2997 ALL patients were diagnosed, i.e. 115 patients (range 87-147) per year. Overall incidence remained stable at 37 per million children, despite increases for B-cell precursor ALL (BCP-ALL) at age 10-14 years (AAPC + 1.4%, p = 0.04) and T-cell ALL at 15-17 years (AAPC + 3.7%, p = 0.01). Five-year survival increased from 80% in 1990-94 to 91% in 2010-15 (p < 0.01). Mortality decreased by 4% annually (p < 0.01). Patients 15-17 years were increasingly treated in a paediatric oncology centre, from 35% in 1990-94 to 87% in 2010-15 and experienced a 70% reduction of risk of death compared to those treated outside such a centre (p < 0.01). Significant progress against childhood ALL has been made in the Netherlands, visible by improved survival rates coinciding with declining mortality rates. These outcomes were accompanied by stable incidence rates, despite increases for BCP-ALL at age 10-14 years and T-cell ALL at age 15-17 years.
It remains unclear if inflammation itself may induce cancer, if inflammation is a result of tumor growth, or a combination of both exists. The aim of this study was to examine whether C-reactive ...protein (CRP) levels and CRP gene variations were associated with an altered risk of colorectal, lung, breast, or prostate cancer.
A total of 7,017 participants age > or = 55 years from the Rotterdam Study were eligible for analyses. Mean follow-up time was 10.2 years. High-sensitivity CRP measurements were performed to identify additional values of 0.2 to 1.0 mg/L compared with standard procedures. Genotypes of the CRP gene were determined with an allelic discrimination assay.
High levels (> 3 mg/L) of CRP were associated with an increased risk of incident cancer (hazard ratio, 1.4; 95% CI, 1.1 to 1.7) compared with persons with low levels (< 1 mg/L), even after a potential latent period of 5 years was introduced. Although CRP seems to affect several cancer sites, the association was strongest for lung cancer (hazard ratio, 2.8; 95% CI, 1.6 to 4.9). A CRP single nucleotide polymorphism associated with decreased CRP levels was associated with an increased lung cancer risk of 2.6 (95% CI, 1.6 to 4.4) in homozygous carriers.
Baseline CRP levels seem to be a biomarker of chronic inflammation preceding lung cancer, even after subtracting a 5-year latent period. Furthermore, CRP gene variation associated with low CRP blood levels was relatively common in patients with lung cancer. Both chronic inflammation and impaired defense mechanisms resulting in chronic inflammation might explain these results.
Several studies observed a female advantage in the prognosis of cutaneous melanoma, for which behavioral factors or an underlying biologic mechanism might be responsible. Using complete and reliable ...follow-up data from four phase III trials of the European Organisation for Research and Treatment of Cancer (EORTC) Melanoma Group, we explored the female advantage across multiple end points and in relation to other important prognostic indicators.
Patients diagnosed with localized melanoma were included in EORTC adjuvant treatment trials 18832, 18871, 18952, and 18961 and randomly assigned during the period of 1984 to 2005. Cox proportional hazard models were used to calculate hazard ratios (HRs) and 95% CIs for women compared with men, adjusted for age, Breslow thickness, body site, ulceration, performed lymph node dissection, and treatment.
A total of 2,672 patients with stage I/II melanoma were included. Women had a highly consistent and independent advantage in overall survival (adjusted HR, 0.70; 95% CI, 0.59 to 0.83), disease-specific survival (adjusted HR, 0.74; 95% CI, 0.62 to 0.88), time to lymph node metastasis (adjusted HR, 0.70; 95% CI, 0.51 to 0.96), and time to distant metastasis (adjusted HR, 0.69; 95% CI, 0.59 to 0.81). Subgroup analysis showed that the female advantage was consistent across all prognostic subgroups (with the possible exception of head and neck melanomas) and in pre- and postmenopausal age groups.
Women have a consistent and independent relative advantage in all aspects of the progression of localized melanoma of approximately 30%, most likely caused by an underlying biologic sex difference.
To study sex differences in survival and progression in patients with stage III or IV metastatic melanoma and to compare our results with published literature.
Data were retrieved from three large, ...randomized, controlled trials of the European Organisation for Research and Treatment of Cancer in patients with stage III and two trials in patients with stage IV melanoma. Cox proportional hazard models were used to calculate hazard ratios (HRs) and 95% CIs for females compared with males, adjusted for different sets of confounders for stage III and stage IV, respectively.
In 2,734 stage III patients, females had a superior 5-year disease-specific survival (DSS) rate compared with males (51.5% v 43.3%), an adjusted HR for DSS of 0.85 (95% CI, 0.76 to 0.95), and an adjusted HR for relapse-free survival of 0.86 (95% CI, 0.77 to 0.95). In 1,306 stage IV patients, females also exhibited an advantage in DSS (2-year survival rate, 14.1% v 19.0%; adjusted HR, 0.81; 95% CI, 0.72 to 0.92) as well as for progression-free survival (adjusted HR, 0.79; 95% CI, 0.70 to 0.88). This female advantage was consistent across pre- and postmenopausal age categories and across different prognostic subgroups. However, the female advantage seems to become smaller in patients with higher metastatic tumor load.
The persistent independent female advantage, even after metastasis to lymph nodes and distant sites, contradicts theories about sex behavioral differences as an explanation for this phenomenon. A biologic sex trait seems to profoundly influence melanoma progression and survival, even in advanced disease.
We examined trends in the incidence and mortality, and described the survival of patients with penile squamous cell carcinoma in the Netherlands between 1989 and 2006. On the basis of nationwide ...population‐based data, 3‐year moving average European age‐standardized incidence and 10‐year relative survival estimates were calculated. Penile squamous cell carcinomas were categorized according to stage grouping based on the TNM classification. In the 17‐year study period, 2000 primary penile cancers were diagnosed in the Netherlands of which 1883 (94%) were squamous cell carcinomas. Median age at diagnosis was 68 years. The majority of patients (57%) were diagnosed with localized tumors (Stage 0 or I). The percentage of missing disease characteristics increased with increasing age. The 3‐year moving average incidence rate of patients with penile squamous cell carcinoma increased significantly from 1.4 per 100,000 person‐years in 1989 to 1.5 in 2006 with an estimated annual percentage of change of 1.3%. Ten‐year relative survival of patients according to the different stage groups was 93% for Stage 0, 89% for Stage I, 81% for Stage II, the 9‐year survival was 50% for patients with Stage III disease and a 2‐year survival of 21% for patients was found for Stage IV disease. Our study shows that the incidence rate of penile squamous cell carcinoma in the Netherlands has increased slightly, especially the incidence of carcinomas in situ. Patients with Stage III and IV tumors have poor survival.
