This study was funded by NHS Lothian Cancer and Leukaemia Endowments Fund. Part of this work was undertaken in the MRC Centre for Reproductive Health which is funded by the MRC Centre grant MR/N022556/1 . STUDY QUESTION What is the impact of cancer in females aged ≤39 years on subsequent chance of pregnancy? SUMMARY ANSWER Cancer survivors achieved fewer pregnancies across all cancer types, and the chance of achieving a first pregnancy was also lower. WHAT IS KNOWN ALREADY The diagnosis and treatment of cancer in young females may be associated with reduced fertility but the true pregnancy deficit in a population is unknown. STUDY DESIGN, SIZE, DURATION We performed a retrospective cohort study relating first incident cancer diagnosed between 1981 and 2012 to subsequent pregnancy in all female patients in Scotland aged 39 years or less at cancer diagnosis (n = 23 201). Pregnancies were included up to end of 2014. Females from the exposed group not pregnant before cancer diagnosis (n = 10 271) were compared with general population controls matched for age, deprivation quintile and year of diagnosis. PARTICIPANTS/MATERIALS, SETTING, METHODS Scottish Cancer Registry records were linked to hospital discharge records to calculate standardized incidence ratios (SIR) for pregnancy, standardized for age and year of diagnosis. Linkage to death records was also performed. We also selected women from the exposed group who had not been pregnant prior to their cancer diagnosis who were compared with a matched control group from the general population. Additional analyses were performed for breast cancer, Hodgkin lymphoma, leukaemia, cervical cancer and brain/CNS cancers. MAIN RESULTS AND THE ROLE OF CHANCE Cancer survivors achieved fewer pregnancies: SIR 0.62 (95% CI: 0.60, 0.63). Reduced SIR was observed for all cancer types. The chance of achieving a first pregnancy was also lower, adjusted hazard ratio = 0.57 (95% CI: 0.53, 0.61) for women >5 years after diagnosis, with marked reductions in women with breast, cervical and brain/CNS tumours, and leukaemia. The effect was reduced with more recent treatment period overall and in cervical cancer, breast cancer and Hodgkin lymphoma, but was unchanged for leukaemia or brain/CNS cancers. The proportion of pregnancies that ended in termination was lower after a cancer diagnosis, and the proportion ending in live birth was higher (78.7 vs 75.6%, CI of difference: 1.1, 5.0). LIMITATIONS, REASONS FOR CAUTION Details of treatments received were not available, so the impact of specific treatment regimens on fertility could not be assessed. Limited duration of follow-up was available for women diagnosed in the most recent time period. WIDER IMPLICATIONS OF THE FINDINGS This analysis provides population-based quantification by cancer type of the effect of cancer and its treatment on subsequent pregnancy across the reproductive age range, and how this has changed in recent decades. The demonstration of a reduced chance of pregnancy across all cancer types and the changing impact in some but not other common cancers highlights the need for appropriate fertility counselling of all females of reproductive age at diagnosis.

Background: Those living in rural areas have poorer cancer outcomes, but current evidence on how rurality impacts melanoma care and survival is contradictory.Aim: To investigate the impact of rurality on setting of melanoma excision and mortality in a whole-nation cohort.Design and Setting: Analysis of linked routine healthcare data comprising every individual in Scotland diagnosed with melanoma, January 2005-December 2013, in primary and secondary care.Method: Multivariate binary logistic regression was used to explore the relationship between rurality and setting of melanoma excision; Cox proportional hazards regression between rurality and mortality was used, with adjustments for key confounders.Results: In total 9519 patients were included (54.3% [n = 5167] female, mean age 60.2 years [SD 17.5]). Of melanomas where setting of excision was known, 90.3% (n = 8598) were in secondary care and 8.1% (n = 771) in primary care. Odds of primary care excision increased with increasing rurality/remoteness. Compared with those in urban areas, those in the most remote rural locations had almost twice the odds of melanoma excision in primary care (adjusted odds ratio [aOR] 1.92; 95% confidence interval [CI] = 1.33 to 2.77). No significant association was found between urban or rural residency and all-cause mortality. Melanoma-specific mortality was significantly lower in individuals residing in accessible small towns than in large urban areas (adjusted hazards ratio [HR] 0.53; 95% CI = 0.33 to 0.87) with no trend towards poorer survival with increasing rurality.Conclusion: Patients in Scottish rural locations were more likely to have a melanoma excised in primary care. However, those in rural areas did not have significantly increased mortality from melanoma. Together these findings suggest that current UK melanoma management guidelines could be revised to be more realistic by recognising the role of primary care in the prompt diagnosis and treatment of those in rural locations.

Abstract: To investigate the laterality of cutaneous melanoma (ICD-10 C43), we obtained data spanning the period of diagnosis 1998–2003 from six population-based cancer registries: New South Wales, Australia; England; Finland; The Netherlands; Scotland; and the Surveillance Epidemiology and End Results (SEER) Program of the United States of America (restricted to ‘White’ race category only). For cases with laterality recorded, the overall ratios of left- to right-sided tumours were calculated. We found that left to right ratios were consistently greater than 1.00, ranging from 1.08 (New South Wales, Australia and US SEER ‘White’) to 1.18 (Scotland), with an overall ratio for all registries combined of 1.10 (95% confidence interval 1.08–1.11). There were no statistically significant differences by sex or age group for all sub-sites combined, or for upper limb or lower limb melanomas. The excess of left-sided tumours seems unlikely to be explained by chance or recording bias. The most likely explanations would appear to be either differences in sun exposure and/or asymmetry of melanocyte distribution or characteristics arising at the time of embryological development.

Background Survivors of childhood leukemia and lymphoma experience high risks of second malignant neoplasms. We quantified such risk using a large dataset from 13 population-based cancer registries. Methods The registries provided individual data on cases of leukemia, Hodgkin lymphoma, and non-Hodgkin lymphoma occurring in children aged 0–14 years and on subsequent second malignant neoplasms for different time periods from 1943 to 2000. Risks of second malignant neoplasms were assessed through standardized incidence ratios (SIRs) and corresponding 95% confidence intervals (CIs), using the incidence rates in the general populations covered by the registries as a reference. Cumulative absolute risks were also calculated. Results A total of 133 second malignant neoplasms were observed in 16540 patients (12731 leukemias, 1246 Hodgkin lymphomas, and 2563 non-Hodgkin lymphomas) after an average follow-up of 6.5 years. The most frequent second malignancies after leukemia were brain cancer (19 cases, SIR = 8.52, 95% CI = 5.13 to 13.3), non-Hodgkin lymphoma (nine cases, SIR = 9.41, 95% CI = 4.30 to 17.9), and thyroid cancer (nine cases, SIR = 18.8, 95% CI = 8.60 to 35.7); the most frequent after Hodgkin lymphoma were thyroid cancer (nine cases, SIR = 52.5, 95% CI = 24.0 to 99.6), breast cancer (six cases, SIR = 20.9, 95% CI = 7.66 to 45.4), and neoplasms of skin (non-melanoma) (six cases, SIR = 34.0, 95% CI = 12.5 to 74.0); and the most frequent after non-Hodgkin lymphoma were thyroid cancer (six cases, SIR = 40.4, 95% CI = 14.8 to 88.0) and brain cancer (four cases, SIR = 6.97, 95% CI = 1.90 to 17.9). Cumulative incidence of any second malignant neoplasm was 2.43% (95% CI = 1.09 to 3.78), 12.7% (95% CI = 8.29 to 17.2), and 2.50% (95% CI = 1.04 to 3.96) within 30 years from diagnosis of leukemia, Hodgkin lymphoma, and non-Hodgkin lymphoma, respectively. Conclusions This population-based study provides, to our knowledge, the most precise and up-to-date estimates for relative and absolute risks of second malignant neoplasms after childhood leukemia and lymphoma.

The incidence of thyroid cancer is increasing in several countries. The aim was to investigate trends in the incidence and mortality of thyroid cancer in Scotland, where thyroid cancer is relatively uncommon, between 1960 and 2002.Descriptive epidemiological study.Thyroid cancer registrations between 1960 and 2000 were obtained from the Scottish Cancer Registry. Mortality data (1960–2002) and population estimates were supplied by the Registrar General for Scotland. Incidence and mortality data are expressed as age-specific rates and European age-standardized rates (EASRs).Thyroid cancer was three times more common in females than in males and was more common in older than younger age groups. Between 1960 and 2000, the annual EASR of thyroid cancer increased from 1·76 to 3·54 per 100 000 for females (P < 0·001) and from 0·83 to 1·25 per 100 000 in males (P < 0·001). The overall thyroid cancer increase between 1975 and 2000 was primarily caused by an increase in papillary thyroid cancer, particularly over the most recent decade. The incidence of follicular thyroid cancer also increased while the incidence of anaplastic and medullary thyroid cancer did not change significantly. Mortality from thyroid cancer fell progressively between 1960 and 2002. EASR for females decreased from 1·05 to 0·28 (P < 0·001) and in males from 0·73 to 0·34 (P < 0·001). For both sexes, in general, survival at 1-, 5- and 10-year follow-up intervals from diagnosis improved steadily over the study period. In both females and males, survival from thyroid cancer was better if the diagnosis was made under the age of 50 years.Thyroid cancer incidence has increased in Scotland over the past 40 years. This is accompanied by a change in the distribution of histological type with a particular increase in papillary carcinoma. The reasons for this may relate partly to changes in clinical practice and histological criteria. Falling mortality in the face of increasing incidence reflects improvements in survival, which should improve further with the introduction and implementation of standardized treatment protocols.

The article presents the views of the clinical director of Scottish Bowel Screening Programme, Robert J. C. Steele, and the director of Scottish Cancer Registry, David H. Brewster, on using cancer specific mortality for judging cancer screening programmes. It states that screening reduces disease specific mortality, and the randomized trials carried out for breast and colon cancer show 20 percent reduction in disease specific mortality.

Background Melanomas are initially excised in primary care, and rates vary internationally. Until now, there has been no strong evidence one way or the other that excising melanomas in primary care is safe or unsafe. European guidelines make no recommendations, and the United Kingdom (UK) melanoma guidelines require all suspicious skin lesions to be initially treated in secondary care based on an expert consensus, which lacks supporting evidence, that primary care excision represents substandard care. Despite this, studies have found that up to 20% of melanomas in the UK are excised by general practitioners (GPs). Patients receiving primary care melanoma excision may fear that their care is substandard and their long-term survival threatened, neither of which may be justified. Methods Scottish cancer registry data from 9367 people diagnosed with melanoma in Scotland between 2005 and 2013 were linked to pathology records, hospital data and death records. A Cox proportional hazards regression analysis, adjusting for key confounders, explored the association between morbidity and mortality and setting of primary melanoma excision (primary versus secondary care). A pooled estimate of the relative hazard of death of having a melanoma excised in primary versus secondary care including 7116 patients from a similar Irish study was also performed. Results The adjusted hazard ratio (95% CI) of death from melanoma for those having primary care excision was 0.82 (0.61–1.10). Those receiving primary care excision had a median (IQR) of 8 (3–14) out-patient attendances compared to 10 (4–17) for the secondary care group with an adjusted relative risk (RR) (95% CI) of 0.98 (0.96–1.01). Both groups had a median of 1 (0–2) hospital admissions with an adjusted rate ratio of 1.05 (0.98–1.13). In the meta-analysis, with primary care as the reference, the pooled adjusted hazard ratio (HR, 95% CI) was 1.26 (1.07–1.50) indicating a significantly higher all-cause mortality among those with excision in secondary care. Conclusions The results of the Scottish and pooled analyses suggest that those receiving an initial excision for melanoma in primary care do not have poorer survival or increased morbidity compared to those being initially treated in secondary care. A randomised controlled trial to inform a greater role for GPs in the initial excision of melanoma is justified in the light of these results. [ABSTRACT FROM AUTHOR]

Introduction: We investigated survival in breast cancer patients by age group, focussing on those covered by screening programmes, using data from 12 European population-based cancer registries participating in the European Network for Indicators on Cancer Survival Working Group. Methods: We calculated period estimates of 5-year relative survival for 2000–2004 and examined the change in survival estimates for four age groups between 1990–1994 and 2000–2004. Trends in age specific incidence, survival and mortality were additionally compared to those in the United States based on results from the Surveillance Epidemiology and End Results (SEER) programme. Results: Breast cancer survival uniformly increased particularly in areas with lower breast cancer survival for patients diagnosed in 1990–1994. With the exception of Geneva, Scotland and Estonia, the rise in survival was always larger among the younger age groups than in the 70+ age group and the age-gradient widened over time. The 5-year relative survival of patients aged 70 and above in the European registries was at least 7 percentage points lower than the 5-year relative survival of patients in the same age group in the US in 2000–2004. During the study period, incidence increased in all age groups and populations with a few exceptions, an observation paralleled by declining mortality. Conclusions: Results showed that some of the geographical differences in overall survival are even larger when considering age groups, in particular between Western and Eastern European countries. Furthermore, some of the differences in survival within the Northern and Western European areas could be due to variations in the implementation of screening programmes rather than economic inequalities.

Abstract: Background: Lung and upper aero-digestive tract (UADT) cancer risk is associated with socioeconomic inequality (SEI) but the degree of socioeconomic burden by age, tumour subtype, and sex is not known. Methods: We reviewed 216,305 cases excluding non melanoma skin cancer (All Cancer) comprising 37,274 lung; 8216 head and neck; and 6534 oesophageal cancers from 2000 to 2007 classified into anatomical or morphology subtypes. Deprivation was measured using the Scottish Index of Multiple Deprivation and SEI was measured using the Slope Index of Inequality and the Relative Index of Inequality (RII). Analyses were partitioned by 5-year age group and sex. RII was adapted to rank tumour type contribution to All Cancer SEI and to examine subtype by age and sex simultaneously. Rank was defined as proportion of All Cancer SEI. Results: All Cancer SEI was greater for males (RII=0.366; female RII=0.279); the combination of lung and UADT SEI contributed 91% and 81% respectively to All Cancer SEI. For both sexes lung and UADT subtypes showed significant SEI (P <0.001) except oesophageal adenocarcinoma in males (P =0.193); for females, SEI was borderline significant (P =0.048). Although RII rank differed by sex, all lung and larynx subtypes contributed most to All Cancer SEI with RII rank for oral cavity, oesophagus-squamous cell, and oropharynx following. For males 40–44 years, SEI increased abruptly peaking at 55–59 years. For females, SEI gradually peaked 10 years later. In both sexes, the SEI peak preceded peak incidence. Conclusion: SEI in lung and UADT cancers vary greatly by age, tumour subtype and sex; these variations are likely to largely reflect differences between the sexes in risk behaviours which vary by birth cohort and are socioeconomically patterned.
