Abstract
BACKGROUND Molar pregnancies, encompassing complete and partial moles, represent a rare and enigmatic gestational disorder with potential ethnic variations in incidence. This study aimed to investigate relations of ethnicity with risks of complete and partial molar pregnancies within an Israeli population while accounting for age differences. METHODS A retrospective study was conducted of data recorded during 2007-2021 in an academic medical center in Israel. The study population comprised 167 women diagnosed with complete or partial moles, for whom data were obtained through histological examination and P57 immunostaining. Maternal age and ethnicity were extracted from electronic medical records. Incidence rates were calculated per 10,000 live births, and a nested case-control study compared demographic characteristics and molar pregnancy incidences between Arab and Jewish women. Statistical analyses included age-adjusted comparisons, relative risk calculations and multivariate logistic regression. RESULTS The overall risk of molar pregnancy was 22 per 10,000 live births (95% confidence interval [CI] 18-25). Among Arab women, the overall risk was 21 (95% CI 17-25), and for PM and CM: 14 (95% CI 11-17) and 7 (95% CI 5-10), respectively. Among Jewish women, the overall risk was 23 (95% CI 18-29), and for PM and CM: 12 (95% CI 8-17) and 11 (95% CI 7-16), respectively. Among Arab women compared to Jewish women, the proportion of all the partial moles was higher: (65.3% vs. 51.6%, p = 0.05). The incidence of partial mole was higher among Arab than Jewish women, aged 35-39 years (26 vs. 8 per 10,000, p = 0.041), and did not differ in other age groups. After adjusting for age, the relative risk of partial moles was lower among Jews than Arabs (0.7, 95% CI 0.4-1.0, p = 0.053). For Arab compared to Jewish women, the mean age at molar pregnancies was younger: 31.0 vs. 35.1 years. However, other factors did not differ significantly between Arab and Jewish women with molar pregnancies. In multivariate analysis, Jewish ethnicity was significantly associated with a higher risk of complete molar pregnancies (OR = 2.19, 95% CI 1.09-4.41, p = 0.028). CONCLUSION This study highlights ethnic differences in molar pregnancy risk within the Israeli population. Jewish ethnicity was associated with a higher risk of complete molar pregnancies, while Arab women had a significantly higher risk of partial moles. These findings underscore the need to consider ethnicity when studying gestational disorders. Further research should seek to elucidate the underlying factors contributing to these differences.

Changing Trends in the Clinical Presentation and Incidence of Molar Pregnancy in Saudi Arabia: A 30-Year Retrospective Analysis. Cureus 2023; 15:e50936.

Abstract
Background Molar pregnancy (MP) incidence and clinical presentation vary significantly worldwide. Recent trends show changes in its clinical representation and incidence, particularly with the adoption of early diagnosis using first-trimester ultrasonography, which has reduced the prevalence of classical second-trimester presentations. This study aimed to analyze the changes in clinical presentation and incidence of MP among the Saudi population over the past 30 years. Methods In this retrospective study at King Fahad University Hospital, 121 complete mole (CM) pregnancy cases diagnosed and pathologically confirmed were reviewed. This included 87 cases from 2007 to 2022 (recent group) and 34 cases from 1992 to 2006 (older group). Cases of CM diagnosed before January 1992 and other diagnoses such as PM, invasive mole, or choriocarcinoma were excluded; thus, this study is focused on CM in particular. We compared patient age, gravidity, parity, abortion history, gestational age at diagnosis, hyperemesis gravidarum symptoms, anemia symptoms, and hemoglobin levels. Classical symptoms and signs related to CM were also reviewed. Data were analyzed using Microsoft Excel 2021 (Microsoft Corporation, Redmond, Washington, United States) and presented as mean, frequency, and percentage, with chi-squared tests for categorical variables; p<0.05 was considered statistically significant. Results The incidence of CM declined from 2.1 per 1,000 deliveries to 0.9 per 1,000 deliveries. Vaginal bleeding was the most common presentation in both the older (91.9%) and recent (67.6%) groups. Hyperemesis gravidarum prevalence was similar in both groups. Theca-lutein cysts were more frequent in the older group (27.5%) than the recent group (8.8%). A significant difference was observed in the occurrence of a large-for-date uterus between the older (63.20%) and recent (23.5%) groups. Notably, 14.7% of patients in the recent group were asymptomatic at diagnosis. Anemia was present in 46 cases (52.8%) of the older group but absent in the recent group, and preeclampsia occurred in 10 cases (11.4%) of the older group but not in the recent group. Conclusions Advancements in ultrasound technology, including transvaginal probes with Doppler capabilities, have enabled earlier pregnancy diagnosis, as early as five to six weeks of gestation. Many MP are now diagnosed in the first trimester without the classic clinical symptoms or "snow-storm" ultrasound appearance. The availability of sensitive beta-human chorionic gonadotropin assays has led to the early termination of these pregnancies, marking a significant shift in the management of MP.

Eur J Obstet Gynecol Reprod Biol 2022; 274:136-141. [PMID: 35640442 DOI: 10.1016/j.ejogrb.2022.05.026] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 05/04/2022] [Accepted: 05/22/2022] [Indexed: 11/26/2022]
Abstract
OBJECTIVE Molar pregnancy is the most common type of gestational trophoblastic disease. Several recent reports have described changes in the clinical representation, the incidence and the diagnostic sensitivity of molar pregnancy. These changes could be due to widespread use of transvaginal ultrasound and beta-hCG testing in the management of routine first-trimester investigations. STUDY DESIGN This is a retrospective study of 144 women diagnosed with partial or complete mole at a regional medical center during 2007-2020. Incidence, demographics, clinical features and diagnostic sensitivity were compared between 2007 and 2014 and 2015-2020, and attempts were made to understand the bases of the changes between the time periods. RESULTS Sixty-two moles were diagnosed during 2007-2014 and 82 during 2015-2020. The proportions of complete moles in the respective periods were 65% (40) and 18% (15). From the earlier to the later period, the incidence and proportion of complete moles decreased, and of partial moles, increased. The median gestational age at diagnosis of molar pregnancy was 9.3 weeks. In the later period, women presented less frequently with vaginal bleeding, though this remained the most common presenting symptom. The proportion of women who underwent surgical evacuation of the uterus due to suspected molar pregnancy decreased, as did the proportion of moles that was suspected in ultrasound evaluation (P < 0.001). CONCLUSION The proportion of complete moles decreased between the periods examined. Gestational age at diagnosis was similar to data from 1994 to 2013. Some typical presenting symptoms of molar pregnancy decreased. However, earlier diagnosis of missed abortion can miss diagnoses of molar pregnancy.

Abstract
Cervical partial hydatidiform mole is a rare condition and difficult to diagnose. A 39-year-old Balinese woman from Sanglah General Hospital, Bali, Indonesia complained vaginal bleeding with abdominal pain. The patient was diagnosed with a partial hydatidiform mole based on physical examination, ultrasound, beta HCG levels and pathology examinations. Mass evacuation surgery followed by arterial ligation to stop the bleeding and periodically examination of beta HCG levels was carried out until the 14th week after the procedure. Beta HCG decreased gradually to normal level and indicate no risk of trophoblastic malignancy. Establishing the early diagnosis significantly affects the outcome of patient.

Mod Pathol 2021; 34:961-982.

Abstract
Immunohistochemical analysis of p57 expression and molecular genotyping accurately subclassify molar specimens into complete hydatidiform mole (CHM) and partial hydatidiform mole (PHM) and distinguish these from nonmolar specimens. Characteristics of a prospective series of potentially molar specimens analyzed in a large gynecologic pathology practice are summarized. Of 2217 cases (2160 uterine, 57 ectopic), 2080 (94%) were successfully classified: 571 CHMs (570 uterine, 1 ectopic), 498 PHMs (497 uterine, 1 ectopic), 900 nonmolar (including 147 trisomies, 19 digynic triploids, and 4 donor egg conceptions), and 56 androgenetic/biparental mosaics; 137 were complex or unsatisfactory and not definitively classified. CHMs dominated in patients aged < 21 and >45 years and were the only kind of molar conception found in the latter group. Of 564 successfully immunostained CHMs, 563 (99.8%) were p57-negative (1 p57-positive [retained maternal chromosome 11] androgenetic by genotyping). Of 153 genotyped CHMs, 148 (96.7%) were androgenetic (85% monospermic) and 5 were biparental, the latter likely familial biparental hydatidiform moles. Of 486 successfully immunostained PHMs, 481 (99%) were p57-positive (3 p57-negative [loss of maternal chromosome 11], 2 unknown mechanism). Of 497 genotyped PHMs, 484 (97%) were diandric triploid (99% dispermic) and 13 were triandric tetraploid (all at least dispermic). Of 56 androgenetic/biparental mosaics, 37 had a p57-negative complete molar component (16 confirmed as androgenetic by genotyping). p57 expression is highly correlated with genotyping, serving as a reliable marker for CHMs, and identifies molar components and androgenetic cell lines in mosaic conceptions. Correlation of morphology, p57 expression, genotyping data, and history are required to recognize familial biparental hydatidiform moles and donor egg conceptions, as the former can be misclassified as nonmolar and the latter can be misclassified as dispermic CHM on the basis of isolated genotyping results.

Abstract
Incidences of hydatidiform mole (HM) registered in European countries varies from 0.98/1000 to 2.17/1000 deliveries, while higher incidences have been reported in other parts of the world. We calculated the incidence by selecting data on HMs classified as ”first”, “second” and “third” from 01.01.1999 to 31.12.2014 registered in the Danish Pathology Registry, which we previously showed to be the most complete data source on the number of HMs in Denmark. In the study period, 1976 first HMs were registered; 1080 (55%) were classified as PHMs (partial HMs) and 896 (45%) as NPHMs (HMs not registered as PHMs). The average incidence of HM was 1.98/1000 deliveries. The incidence of PHM was 1.08/1000 deliveries and the incidence of NPHM was 0.90/1000 deliveries. Forty HMs were registered as second HMs; 85% (34/40) were of the same histopathological type as the first HM. The registered incidence of HM decreased from 2.55/1000 deliveries in 1999 to 1.61/1000 deliveries in 2014 (p < 0.005). The decrease in the incidence of HM was identical with a decrease in the incidence of PHM. New medical practices such as medical abortion and only forwarding selected pregnancy products for histopathologic examination may cause a declining number of HMs registered.

Abstract
Introduction We investigated the rate and longitudinal trends of gestational trophoblastic disease (GTD) incidence in the Republic of Korea between 2009 and 2015 using population-based data. Materials and Methods Data of patients diagnosed with GTD from 2009 to 2015 were obtained from the Health Insurance Review and Assessment Service/National Inpatient Sample (HIRA-NIS) in the Republic of Korea. The HIRA annually provides the HIRA-NIS, a collection of clinical data from over one million people. For each year, the HIRA-NIS extracted records of 13% of patients admitted at any one time during the year and 1% of all remaining patients using the weighted sample method. Results Medical records of 370,117 women with at least one pregnancy (GTD, ectopic pregnancy, abortion, or delivery) were extracted from a total of 4,476,495 records. Of these, 372 episodes of GTD were identified in women with a mean age of 35.4 ± 0.7 years. The incidence rate of GTD was 130 ± 10 cases per 100,000 pregnancies, which was classified as hydatidiform mole (HM), invasive mole, or malignant neoplasm of the placenta with incidence rates of 110 ± 10, 20 ± 0, or 10 ± 0 cases per 100,000 pregnancies, respectively. Incidence of GTD was lowest among women in their late 20 s and early 30 s. Occurrences of HM accounted for 80.3% all GTD cases. Weighted logistic analysis indicated that while age significantly affected the incidence of GTD (odds ratio (OR): 2.46; 95% confidence interval (CI) [1.79–3.37]; P < 0.001), socioeconomic status did not (OR: 1.94; 95% CI [1.0–3.79]; P = 0.05). Conclusions In the Republic of Korea, we observed overall incidence rates of GTD and HM of 1.3 and 1.1 per 1,000 pregnancies, respectively, which are similar to those reported in recent Western population-based studies. We also noted that annual incidence rates of GTD stabilized from 2009 to 2015.

Is there uniformity in definitions and treatment of gestational trophoblastic disease in Europe? Int J Gynecol Cancer 2019; 29:108-112. [DOI: 10.1136/ijgc-2018-000028] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2018] [Revised: 08/29/2018] [Accepted: 09/06/2018] [Indexed: 11/04/2022] Open
Abstract
ObjectivesBecause gestational trophoblastic disease is rare, little evidence is available from randomized controlled trials on optimal treatment and follow-up. Treatment protocols vary within Europe, and even between different centers within countries. One of the goals of the European Organization for Treatment of Trophoblastic Diseases (EOTTD) is to harmonize treatment in Europe. To provide a basis for international standardization of definitions, treatment and follow-up protocols in gestational trophoblastic disease, we evaluated differences and similarities between protocols in EOTTD countries.MethodsMembers from each EOTTD country were asked to complete an online structured questionnaire comprising multiple-choice and multiple-answer questions. The following themes were discussed: incidence of gestational trophoblastic disease and gestational trophoblastic neoplasia, definitions, guidelines, classification system, treatment, recurrence, and follow-up.ResultsForty-four respondents from 17 countries participated in this study. Guidelines were present in 80% of the countries and the FIGO (Fédération Internationale de Gynécologie et d'Obstétrique) staging and risk classification was often used to estimate risks. Agreement about when to start chemotherapy for post-molar gestational trophoblastic neoplasia was present among 66% of the respondents. Preferred first-line treatments in low- and high-risk gestational trophoblastic neoplasia were methotrexate (81%) and EMA-CO (etoposide, methotrexate, actinomycin D, cyclophosphamide, vincristine) (93%), respectively. The definition of human chorionic gonadotropin normalization after hydatidiform mole evacuation was two consecutive normal values for nine countries. The FIGO definition of post-molar gestational trophoblastic neoplasia based on human chorionic gonadotropin plateau or rise was agreed on by 69% of respondents, and only 69% and 74% defined low-risk and high-risk disease, respectively, using FIGO criteria. There were major differences in definitions of recurrence, chemotherapy resistance and follow-up protocols among countries, despite EOTTD consensus statements.ConclusionsThis questionnaire provides a good overview of current clinical practices in different countries. Based on the survey results, it is clear that there are several gestationaltrophoblastic disease-related topics that need urgent attention within the EOTTD community to create more uniformity and to aid the development of uniform guidelines in Europe.

Abstract
Purpose To examine the validity of registration of hydatidiform mole (HM) in the Danish National Patient Registry (NPR), the Danish Cancer Registry (DCR), and the Danish Pathology Registry (DPR). Patients and methods We selected women registered with a first-time HM code in NPR, DCR, and DPR from 1999 to 2009. We found most women registered in DPR. For a random sample of women registered in DPR, the coding was validated by comparing with the pathology report. Completeness and positive predictive value (PPV) of registration with an HM code in NPR and DCR were calculated using DPR as the reference. Details of women registered in NPR or DCR, but not in DPR, were scrutinized. Results In NPR and DPR, 1,520 women were identified in total; 1,057 (70%) were found in both registries, 65 (4%) only in NPR, and 398 (26%) only in DPR. In DCR and DPR, 1,498 women were identified in total; 1,174 (78%) in both registries, 47 (3%) only in DCR, and 277 (19%) only in DPR. For 149/150 randomly selected women registered with an HM code in DPR (99%), the pathology report was consistent with the diagnosis of HM. Completeness of NPR was 73% (95% CI: 70%–75%) and PPV was 94% (95% CI: 93%–95%). Completeness of DCR was 72% (95% CI: 69%–75%) in 1999–2003 and 90% (95% CI: 87%–92%) in 2004–2009. PPV of DCR was 96% (95% CI: 95%–97%) throughout the period. Conclusion Validation of registry data is important before using these. For research on the number of HMs in Denmark, DPR is the most valid data source. NPR and DCR appear to be equally valid before 2004. However, for research after 2004, DCR should be preferred rather than NPR.

Abstract
BACKGROUND Reported incidence rates of hydatidiform mole (HM) show wide geographic and temporal variations, making reliable international comparisons difficult. The aim of the current study was to examine temporal trends in the incidence of HM and post-molar gestational trophoblastic neoplasia (GTN) in Stockholm County. MATERIAL AND METHODS Data of all women with a diagnosis of HM in Stockholm County 1991-2010 was collected. The incidence of HM was assessed both in relation to number of births and viable conceptions (births and pregnancy terminations). The risk of post-molar GTN was analysed for all HM, as well as for the subtypes complete (CHM) and partial hydatidiform mole (PHM). Temporal trends were analysed by stratifying the study period into five-year intervals. RESULTS The overall incidence rate of HM was 2.08/1000 deliveries and 1.48/1000 viable conceptions. A significant temporal increase in the incidence rate of HM, as well as in the total number and proportion of PHM, was seen. Among 956 women with HM, 77 (8%) progressed into post-molar GTN. There was evidence of a slight, but non-significant increase in the risk of malignancy in the two last five-year periods under study. CONCLUSIONS We found evidence of a significant temporal increase in the incidence rate of HM, which could not fully be explained by an increase in maternal age over time. Changes in diagnostic methods probably contributed to the increased incidence rate of PHM. The risk of post-molar GTN remained constant over time.

Abstract
OBJECTIVE The aim of the study was to evaluate potential changes in the clinical, diagnostic, and therapeutic parameters of complete hydatidiform mole in the last 25 years in Brazil. METHODS A retrospective cohort study was conducted involving the analysis of 2163 medical records of patients diagnosed with complete hydatidiform mole who received treatment at the Rio de Janeiro Reference Center for Gestational Trophoblastic Disease between January 1988 and December 2012. For the statistical analysis of the natural history of the patients with complete molar pregnancies, time series were evaluated using the Cox-Stuart test and adjusted by linear regression models. RESULTS A downward linear temporal trend was observed for gestational age of complete hydatidiform mole at diagnosis, which is also reflected in the reduced occurrence of vaginal bleeding, hyperemesis and pre-eclampsia. We also observed an increase in the use of uterine vacuum aspiration to treat molar pregnancy. Although the duration of postmolar follow-up was found to decline, this was not accompanied by any alteration in the time to remission of the disease or its progression to gestational trophoblastic neoplasia. CONCLUSIONS Early diagnosis of complete hydatidiform mole has altered the natural history of molar pregnancy, especially with a reduction in classical clinical symptoms. However, early diagnosis has not resulted in a reduction in the development of gestational trophoblastic neoplasia, a dilemma that still challenges professionals working with gestational trophoblastic disease.

Abstract
Background: International comparisons of perinatal health indicators are complicated by the heterogeneity of data sources on pregnancy, maternal and neonatal outcomes. Record linkage can extend the range of data items available and thus can improve the validity and quality of routine data. We sought to assess the extent to which data are linked routinely for perinatal health research and reporting. Methods: We conducted a systematic review of the literature by searching PubMed for perinatal health studies from 2001 to 2011 based on linkage of routine data (data collected continuously at various time intervals). We also surveyed European health monitoring professionals about use of linkage for national perinatal health surveillance. Results: 516 studies fit our inclusion criteria. Denmark, Finland, Norway and Sweden, the US and the UK contributed 76% of the publications; a further 29 countries contributed at least one publication. Most studies linked vital statistics, hospital records, medical birth registries and cohort data. Other sources were specific registers for: cancer (70), congenital anomalies (56), ART (19), census (19), health professionals (37), insurance (22) prescription (31), and level of education (18). Eighteen of 29 countries (62%) reported linking data for routine perinatal health monitoring. Conclusion: Research using linkage is concentrated in a few countries and is not widely practiced in Europe. Broader adoption of data linkage could yield substantial gains for perinatal health research and surveillance.

Abstract
ObjectiveTo analyze the clinical profile of invasive mole (IM) and choriocarcinoma (CCA) in the past 15 years in Western China.Materials and MethodsA retrospective study was performed on 221 patients with IM and 70 patients with CCA treated in the First Affiliated Hospital of Xi’an Jiaotong University from 1994 to 2009. Patients were assigned into 3 groups by 5 years, and the clinical characteristics were compared among these groups.ResultsThe incidence was not significantly changed in the past 15 years, whereas the mean age of gestational trophoblastic neoplasia (GTN) was increased significantly, especially for the patients 40 years or older. The symptoms of the patients with GTN did not show significant variation, but the number of patients with CCA without clinical symptoms was increased significantly. The mean values of beta human chorionic gonadotropin in the patients with IM and those with CCA were 459.43 and 661.70 mIu/L, respectively, and the size of uterine lesion was concentrated at 4 cm or less in both the patients with IM and those with CCA, without significant differences.ConclusionsIn the past 15 years, the incidence of GTN was still higher than in other countries from 1994 to 2009, and the mean age of patients with GTN was increased significantly, especially for the patients older than 40 years. Furthermore, patients with no clinical manifestations increased significantly, which should be paid more attention in the future works. Serum level of beta human chorionic gonadotropin and pelvic ultrasonography are still 2 important indexes for diagnosing and monitoring condition of GTN.

Abstract
BACKGROUND Prevalence of hydatidiform mole is not clearly defined, partly because most studies have reported different prevalence rates from different regions. However, there is no previous study that has determined the prevalence and associated risk factors of HM among patients with incomplete abortion evacuated at Bugando Medical Centre (BMC) and Sekou Toure Regional Hospital (STRH). METHODS A total of 180 patients with incomplete abortion were enrolled between February 2013 and April 2013. The products of conception were collected and analyzed using Haemotoxylin and Eosin staining technique for hydatidiform moles. RESULTS One hundred and eighty patients with incomplete abortion scheduled for uterine evacuation agreed to participate in this study. The overall prevalence of HM was 12.8%. Majority of patients (27.5%) with HM were those aged below 20 years. No significant association was observed with risk factors such as parity, contraceptive use, previous abortion and blood group. CONCLUSION The prevalence of HM (12.8%) was high and age between 15-20 years was the only significant associated risk factor with the presence of HM among patients with incomplete abortion. Therefore, we recommend submission of evacuated products of conception for histopathological analysis to minimize missed opportunity.

Abstract
OBJECTIVE The objective of the study was to investigate whether a history of hydatidiform mole (HM) is associated with an increased risk of adverse outcomes in subsequent pregnancies. STUDY DESIGN This was a nationwide cohort study with data from population-based registers. The study population consisted of all children registered in the Swedish Medical Birth Register 1973-2009 (n = 3,730,825). Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated for adverse maternal and offspring pregnancy outcomes by maternal history of HM prior to the delivery, with children to women with no maternal history of HM as the reference. Risk estimates were adjusted for maternal age at delivery and maternal country of birth. RESULTS A history of HM was not associated with an increased risk of adverse maternal outcomes in subsequent pregnancies (n = 5186). Women exposed to a molar pregnancy prior to the index birth were at an almost 25% increased risk of preterm birth (OR, 1.23; 95% CI, 1.06-1.43), whereas women with at least 1 birth between the HM and the index birth were at an increased risk of a large-for-gestational-age birth and stillbirth (OR, 1.35; 95% CI, 1.10-1.67 and OR, 1.81; 95% CI, 1.11-2.96, respectively). The risk of repeat mole was 0.4%. CONCLUSION Women with a history of HM are at no increased risk of adverse maternal outcomes in subsequent pregnancies but have an increased risk of large-for-gestational-age birth, stillbirth, and preterm birth. However, in absolute terms, the risk of subsequent adverse offspring outcomes is very low.

Abstract
BACKGROUND The Swedish Cancer Register (SCR), an old and reputable health data register, contributes a large amount of data used in research. The quality of the research using SCR data depends on the completeness and validity of the register. In Sweden, every healthcare provider is obligated to report newly detected cases of cancer to the SCR regardless of the diagnostic basis. This study aimed to clarify whether there is an under-reporting of patients with cancer to the SCR or an over-reporting of cancer as cause of death to the SRPC as all patients do not appear in both registers. In addition, this study looked at the distribution of under-reporting or over-reporting related to age, sex, type of cancer, diagnostic basis, and department responsible for cancer diagnosis. MATERIAL AND METHODS Of the 10 559 patients whose cause of death was cancer as reported to the SRPC (2009), 1394 patients (13.2%) were not registered in the SCR (1958-2009). Medical records from a representative sample of 203 patients were collected and reviewed. RESULTS The medical records for 193 patients were obtained; of those, 183 (95%) patients should have been reported to the SCR. Among these, radiologic investigation was the most common basis for diagnosis and there was a significant over-representation of cancer of the pancreas, lung, liver, and bile ducts. DISCUSSION This study cannot quantify the completeness of the SCR. The findings indicate that 12.5% of patients dying of cancer in palliative care are not reported, that specialized hospital departments diagnose the vast majority of the unreported patients, and that routines for how to report patients to the SCR based on radiological findings should be revised.
