Indicators of cure for women living after uterine and ovarian cancers: a population-based study.

This study aims to estimate long-term survival, cancer prevalence, and several cure indicators for Italian women with gynaecological cancers. Thirty-one cancer registries, representing 47% of the Italian female population, were included. Mixture cure models were used to estimate Net Survival (NS), Cure Fraction, Time To Cure (5-year conditional NS>95%), Cure Prevalence (women who will not die of cancer), and Already Cured (living longer than Time to Cure). In 2018, 0.4% (121,704) of Italian women were alive after corpus uteri cancer, 0.2% (52,551) after cervical, and 0.2% (52,153) after ovarian cancer. More than 90% of patients with uterine cancers and 83% with ovarian cancer will not die from their neoplasm (Cure Prevalence). Women with gynaecological cancers have a residual excess risk of death <5% after 5 years since diagnosis. The Cure Fraction was 69% for corpus uteri, 32% for ovarian, and 58% for cervical cancer patients. Time To Cure was ≤10 years for women with gynaecological cancers aged <55 years. 74% of patients with cervical cancer, 63% with corpus uteri cancer, and 55% with ovarian cancer were Already Cured. These results will contribute to improving follow-up programs for women with gynaecological cancers and supporting efforts against discrimination of already cured ones.

Cure indicators and prevalence by stage at diagnosis for breast and colorectal cancer patients: A population-based study in Italy.

People alive many years after breast (BC) or colorectal cancer (CRC) diagnoses are increasing. This paper aimed to estimate the indicators of cancer cure and complete prevalence for Italian patients with BC and CRC by stage and age. A total of 31 Italian Cancer Registries (47% of the population) data until 2017 were included. Mixture cure models allowed estimation of net survival (NS); cure fraction (CF); time to cure (TTC, 5-year conditional NS >95%); cure prevalence (who will not die of cancer); and already cured (prevalent patients living longer than TTC). 2.6% of all Italian women (806,410) were alive in 2018 after BC and 88% will not die of BC. For those diagnosed in 2010, CF was 73%, 99% when diagnosed at stage I, 81% at stage II, and 36% at stages III-IV. For all stages combined, TTC was >10 years under 45 and over 65 years and for women with advanced stages, but ≤1 year for all BC patients at stage I. The proportion of already cured prevalent BC women was 75% (94% at stage I). Prevalent CRC cases were 422,407 (0.7% of the Italian population), 90% will not die of CRC. For CRC patients, CF was 56%, 92% at stage I, 71% at stage II, and 35% at stages III-IV. TTC was ≤10 years for all age groups and stages. Already cured were 59% of all prevalent CRC patients (93% at stage I). Cancer cure indicators by stage may contribute to appropriate follow-up in the years after diagnosis, thus avoiding patients' discrimination.

Complete prevalence and indicators of cancer cure: enhanced methods and validation in Italian population-based cancer registries.

Objectives: To describe the procedures to derive complete prevalence and several indicators of cancer cure from population-based cancer registries. Materials and methods: Cancer registry data (47% of the Italian population) were used to calculate limited duration prevalence for 62 cancer types by sex and registry. The incidence and survival models, needed to calculate the completeness index (R) and complete prevalence, were evaluated by likelihood ratio tests and by visual comparison. A sensitivity analysis was conducted to explore the effect on the complete prevalence of using different R indexes. Mixture cure models were used to estimate net survival (NS); life expectancy of fatal (LEF) cases; cure fraction (CF); time to cure (TTC); cure prevalence, prevalent patients who were not at risk of dying as a result of cancer; and already cured patients, those living longer than TTC at a specific point in time. CF was also compared with long-term NS since, for patients diagnosed after a certain age, CF (representing asymptotical values of NS) is reached far beyond the patient's life expectancy. Results: For the most frequent cancer types, the Weibull survival model stratified by sex and age showed a very good fit with observed survival. For men diagnosed with any cancer type at age 65-74 years, CF was 41%, while the NS was 49% until age 100 and 50% until age 90. In women, similar differences emerged for patients with any cancer type or with breast cancer. Among patients alive in 2018 with colorectal cancer at age 55-64 years, 48% were already cured (had reached their specific TTC), while the cure prevalence (lifelong probability to be cured from cancer) was 89%. Cure prevalence became 97.5% (2.5% will die because of their neoplasm) for patients alive >5 years after diagnosis. Conclusions: This study represents an addition to the current knowledge on the topic providing a detailed description of available indicators of prevalence and cancer cure, highlighting the links among them, and illustrating their interpretation. Indicators may be relevant for patients and clinical practice; they are unambiguously defined, measurable, and reproducible in different countries where population-based cancer registries are active.

Trends in Liver Cancer Incidence and Survival in Italy by Histologic Type, 2003-2017.

(1) Background: Liver cancer in Italy is characterised by one of the highest incidence rates worldwide outside of Asia coupled with comparatively favourable survival figures. The objective of this study was to evaluate the most recent epidemiologic trends of the disease. (2) Methods: Thirteen cancer registries covering a population of about 12,740,000 (21% of the national population) made available the records of 35,574 cases registered between 2003 and 2017. Trends in age-standardised (Europe 2013) incidence rates were analysed using the results of age-drift models. Trends in survival were analysed using 1-year, 2-year, 5-year and 10-year net survival (NS) and 5|1-year and 5|2-year conditional NS. (3) Results: Over the study period, the average annual incidence rates per 100,000 persons were 29.4 (men) and 9.4 (women) for total liver cancer; 14.6 and 3.5 for hepatocellular carcinoma (HCC); 1.8 and 1.1 for intrahepatic cholangiocarcinoma (ICC); and 13.0 and 4.8 for the 'other liver cancer types' group. The incidence of total liver cancer and HCC decreased significantly for both sexes. For total liver cancer, the estimated average annual percent change was -1.6% among men and -2.1% among women. For HCC, the change was -1.3% among men and -2.7% among women. ICC followed an opposite trend. For men, the risk of HCC had two peaks, one in the birth cohorts of 1928 and 1933 and another, more moderate peak in the cohort of 1958. Men and women exhibited comparable improvements in both early and mid-term conditional NS from HCC. In 2013-2017, 5-year NS was 28.9% (95% CI: 27.3%; 30.6%) for men and 30.1% (95% CI: 26.9%; 33.5%) for women. The uptrend in survival from ICC was less pronounced and was weakly significant, with a 5-year NS in 2013-2017 of 13.9% (95% CI: 10.8%; 17.3%) for men and 17.4% (95% CI: 13.5%; 21.7%) for women. (4) Conclusions: The opposite incidence trends of HCC and ICC confirm a pattern observed in other populations. The generalised, albeit slow, improvement in survival from HCC indicates a trend towards earlier detection coupled with improvements in treatments.

Molecular Subtypes, Metastatic Pattern and Patient Age in Breast Cancer: An Analysis of Italian Network of Cancer Registries (AIRTUM) Data.

Breast cancer stage at diagnosis, patient age and molecular tumor subtype influence disease progression. The aim of this study was to analyze the relationships between these factors and survival in breast cancer patients among the Italian population using data from the AIRTUM national database. We enrolled women with primary breast cancer from 17 population-based cancer registries. Patients were subdivided into older (>69 years), middle (50-69 years) and younger age groups (<50 years) and their primary tumors categorized into four molecular subtypes based on hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) status. There were 8831 patients diagnosed between 2010 and 2012 included. The most represented age group was 50-69 years (41.7%). In 5735 cases the molecular subtype was identified: HER2-/HR+ was the most frequent (66.2%) and HER2+/HR- the least (6.2%). Of the 390 women with metastases at diagnosis, 38% had simultaneous involvement of multiple sites, independent of age and molecular profile. In women with a single metastatic site, bone (20% of cases), liver (11%), lung (7%) and brain (3%) were the most frequent. In the studied age groups with different receptor expression profiles, the tumor metastasized to target organs with differing frequencies, affecting survival. Five-year survival was lowest in women with triple-negative (HER2-/HR-) tumors and women with brain metastases at diagnosis.

Gastric cancer with brain metastasis and the role of human epidermal growth factor 2 status.

Central nervous system (CNS) metastases from cancers of the gastrointestinal tract (GIT) are rare, and occur in 0.16-0.69% of patients with gastric or gastro-esophageal (GE) junction cancer. Overexpression of the human epidermal growth factor 2 (HER-2) is associated with poor prognosis in the absence of HER-2-targeted therapy, and with an increased incidence of CNS metastases in patients with breast cancer. The role of HER-2 overexpression in CNS metastases is not well known in gastric adenocarcinoma. The purpose of the present retrospective study was to assess the incidence of CNS metastases and to evaluate the associations between the CNS and HER-2 status in a series of consecutive patients with gastric or GE junction cancer. Between 2007 and 2013, 300 patients with gastric cancer (GC) or gastroesophageal junction, were admitted to Piacenza General Hospital, Italy. These cases were retrospectively analyzed to evaluate CNS metastases. The metastases were diagnosed with imaging techniques performed on symptomatic patients. Gastric histological samples of patients with CNS metastases were reviewed and tested for HER-2. A total of 7 of the 300 patients (2.33%) with GC were observed to have CNS metastases and 6 (85.71%) had HER-2 positive disease. These patients exhibited a poor prognosis with a median overall survival rate of 4.1 months (range, 2.1-6.6 months). These results suggested there may be CNS recurrence susceptibility in patients with HER-2 positive GC. To the best of our knowledge, this is the first report that associates CNS metastases and HER-2 status in gastric or GE junction cancer.

Thoracentesis in advanced cancer patients with severe thrombocytopenia: Ultrasound guide improves safety and reduces bleeding risk.

BACKGROUND: Patients with severe thrombocytopenia are considered at risk for bleeding during invasive procedures as thoracentesis. The use of ultrasound (US) significantly reduces the rate of pneumothorax from thoracentesis, but there is a lack of data on safety and efficacy of US guidance in reducing bleeding complications in thoracentesis performed on patients with severe thrombocytopenia. METHODS: We retrospectively analysed the efficacy and safety of thoracentesis in cancer patients with severe thrombocytopenia. From January 2005 to December 2011, 462 patients underwent thoracentesis. Procedures were divided into 2 groups: performed without or with US guidance. All procedures were evaluated for bleeding complications as defined by the National Institutes of Health Common Terminology Criteria for Adverse Events. RESULTS: A total of 436 consecutive evaluable thoracentesis were analysed. Thoracentesis was performed with US guidance in 310 cases. Forty-one patients (9.40%) had severe thrombocytopenia. In 32 of these 41 patients, thoracentesis was performed under US guidance while in 9 cases the procedure was performed without US guidance. Three mild haemorrhagic complications (0.69% of the procedures performed) were observed and all occurred in group of the 9 (33.33%) patients with severe thrombocytopenia who underwent thoracentesis without US guidance. No haemorrhagic complications were recorded in the 427 patients, including the 32 patients with severe thrombocytopenia, in whom thoracentesis was performed with US guidance. CONCLUSIONS: US guided thoracentesis is a safe and effective approach in cancer patients with severe thrombocytopenia. Our results indicate that this procedure, when US-guided, can be safety performed even in patients with platelet count below 30 × 109 /L.

[Evaluation of the cancer co-pay fee exemption data source (048 code) to estimate cancer incidence]. / Valutazione del flusso delle esenzioni ticket per neoplasia (codice 048) per stimare l'incidenza dei tumori.

OBJECTIVES: to assess whether the data source of cancer exemption ticket (code 048) correctly estimate the cancer incidence produced by Cancer registries (CR). DESIGN: comparison between incidence estimates produced by cancer exemptions ticket and cases registered by CR. SETTING AND PARTICIPANTS: six CRs provided incidence data for one year in the five-year period from 2007 to 2011 and for the previous five years, the exemptions provided for the same year and for the previous five years. MAIN OUTCOME MEASURES: incidence distribution by gender, age and tumour site, exemptions 048/incident cancers ratio, and trend estimates. RESULTS: out of 14,586 patients with 048 exemption, a first group was present in the CR database in the same reference year (No. 8,015) and a second group in the previous 6 months (No. 1,696). Of the remaining 4,875, only 2,771 were prevalent cases and 2,104 were manually re-valued: 514 non-cancer; 710 non-malignant/noninfiltrating tumours, 250 non-residents, 532 unknown, and 98 lost at CR. The exemption/ tumours ratio was 32%in males and 37% in females. Out of 27,632 cancer patients in CR, only 29% had a 048 exemption. Among linked cases, there is a case-mix problem: the exemptions overestimated the weight of some cancer sites (breast, prostate), but underestimate the weight of other sites (stomach, liver, lung) and the burden of tumours in the elderly.The trend estimated from the exemptions underestimates the true incidence of tumours and presents fluctuations, because of local administrative and organisational issues. CONCLUSIONS: the 048 codes are an accessory source for CRs, but when used as single flow they are not able to estimate the true incidence of tumours and, therefore, do not provide useful information on cancer trends.

Ultrasound guidance reduces pneumothorax rate and improves safety of thoracentesis in malignant pleural effusion: report on 445 consecutive patients with advanced cancer.

BACKGROUND: Malignant pleural effusion (MPE) is an extremely common problem affecting cancer patients, and thoracentesis is an essential procedure in an attempt to delineate the etiology of the fluid collections and to relieve symptoms in affected patients. One of the most common complications of thoracentesis is pneumothorax, which has been reported to occur in 20% to 39% of thoracenteses, with 15% to 50% of patients with pneumothorax requiring tube thoracostomy.The present study was carried out to assess whether thoracenteses in cancer patients performed with ultrasound (US) guidance are associated with a lower rates of pneumothorax and tube thoracostomy than those performed without US guidance. METHODS: A total of 445 patients were recruited in this retrospective study. The medical records of 445 consecutive patients with cancer and MPE evaluable for this study, undergoing thoracentesis at the Oncology-Hematology and Internal Medicine Departments, Piacenza Hospital (Italy) were reviewed. RESULTS: From January 2005 to December 2011, in 310 patients (69.66%) thoracentesis was performed with US guidance and in 135 (30.34%) without it. On post-thoracentesis imaging performed in all these cases, 15 pneumothoraces (3.37%) were found; three of them (20%) required tube thoracostomy. Pneumothorax occurred in three out of 310 procedures (0.97%) performed with US guidance and in 12 of 135 procedures (8.89%) performed without it (P<0.0001). It must be emphasized that in all three patients with pneumothorax requiring tube thoracostomy, thoracentesis was performed without US guidance. CONCLUSIONS: The routine use of US guidance during thoracentesis drastically reduces the rate of pneumothorax and tube thoracostomy in oncological patients, thus improving safety as demonstrated in this study.

Screening patterns within organized programs and survival of Italian women with invasive cervical cancer.

OBJECTIVES: To evaluate screening patterns within organized cervical screening programs (OCSPs) and survival of women with invasive cervical cancer (ICC). METHODS: A population-based study was conducted in Italian areas covered by cancer registries and OCSPs. The study included all women aged 25-65 years diagnosed with ICC between 1995 and 2008, and their screening histories within OCSPs were retrieved. Hazard ratios (HR) of death and 95% confidence intervals (CI) were computed according to screening pattern, using Cox models adjusted for age, ICC stage, and major confounders. RESULTS: Among 3268 women with ICC, 20% were never-invited to OCSP, 36% were never-compliant with OCSP's invitation, 33% were compliant and had a screen-detected ICC within OCSP (i.e., after a positive cytology), and 11% were compliant but had a non-screen-detected ICC. Screen-detected ICCs were more frequently micro-invasive (42%) compared to non-screen-detected ones (14%). Compared to women with screen-detected ICC, the adjusted HRs of death were 1.9 (95% CI 1.5-2.4) for those never-invited, 2.0 (95% CI 1.6-2.5) for never-compliant, and 1.7 (95% CI 1.3-2.4) for compliant women having non-screen-detected ICC. CONCLUSION: Prolonged survival, beyond down-staging, of women with ICC detected within OCSPs in Italy, further calls for improvements of OCSPs' invitational coverage and participation.

Elderly cancer patients' preferences regarding the disclosure of cancer diagnosis. Experience of a single institution in Italy.

The disclosure of a diagnosis of cancer is complex, particularly in older patients for reasons related to the wishes of the family, fear of discouraging the patient, or the patient's inability to understand the information. So our insight into older people's perspectives regarding the disclosure of their cancer diagnosis is fragmentary and inadequate. To examine the views of older adults regarding this issue, we performed a prospective observational study in an inpatient oncology clinic. From January 2006 to June 2006, a sample of 132 consecutive cancer patients aged over 70 years with a variety of solid tumors, recently diagnosed and mainly at an advanced stage, agreed to take part in a survey about the disclosure of the diagnosis of their disease. Of the 132 patients who verbally agreed to participate and were given questionnaires, 106 returned data. The majority of patients (64.1%) in this study wanted to be informed about the diagnosis of their disease also if it was cancer, and 58.5% were in fact informed about the exact nature of their disease. Male patients were more keen to know the diagnosis than female patients (P = 0.002) and they were in fact more informed about their diagnosis than female patients (P = 0.005). Patients with more formal education were more informed than patients with less formal education (P = 0.035). This study demonstrates that the preferences of older patients regarding cancer diagnosis disclosure are highly similar to those of younger people. Male patients and patients with more formal education were more informed than female patients and patients with less formal education.

High grade B-cell gastric lymphoma with complete pathologic remission after eradication of Helicobacter pylori infection: report of a case and review of the literature.

BACKGROUND: Treatment of primary gastric diffuse large B-cell lymphoma is still controversial. The treatment of localized disease was based on surgery alone, or followed by chemotherapy and/or radiotherapy. High-grade gastric lymphomas are generally believed to be Helicobacter pylori (HP)-independent growing tumors. However a few cases of regression of high-grade gastric lymphomas after the cure of Helicobacter pylori infection had been described. CASE PRESENTATION: We report here a case with primary diffuse large B-cell lymphoma that showed a complete pathologic remission after HP eradication and we reviewed the literature. A computerized literature reach through Medline, Cancerlit and Embase were performed, applying the words: high grade gastric lymphoma, or diffuse large B cell, MALT gastric lymphoma, DLBCLL (MALT) lymphoma and Helicobacter. Articles and abstracts were also identified by back-referencing from original and relevant papers. Selected for the present review were papers published in English before January 2007. CONCLUSION: Forty two cases of primary high grade gastric lymphoma that regressed with anti HP treatment were found. There were anecdotal cases reported and patients belonging to prospective studies; four trials studied the effect of eradication of Helicobacter pylori as first line therapy in high grade gastric lymphoma: 22 of a total of 38 enrolled patients obtained complete remission. Depth of gastric wall infiltration and clinical stage were important factors to predict the response to antibiotic therapy. Our case and the review of the literature show that high-grade transformation is not necessarily associated with the loss HP dependence. In early stage, for high-grade B-cell HP-positive gastric lymphomas, given the limited toxicity of anti-HP therapy, this treatment may be considered as one of the first line treatment options.

Cancer diagnosis disclosure in a northern Italian hospital. Report on 312 consecutive cancer patients.

To evaluate cancer diagnosis disclosure in a cohort of cancer patients attending an outpatient oncology unit, a prospective observational study was performed. Three hundred twelve consecutive patients were accrued between January and June 2005. A questionnaire was given to each patient; the questions were very simple and related to demographics, residence, sex, educational background, employment status, time elapsed after diagnosis, treatment received, existence of relatives, and health insurance. All patients but one entered the study. There were 185 women and 127 men; 120 patients had breast cancer, 84 colorectal cancer, 34 lung cancer, 28 ovarian cancer, 34 gastric cancer, and 12 pancreatic cancer. Of the total 311 evaluable cancer patients, 171 (54.98%) were correctly informed; of the remaining 140 patients, 67 (21.54%) were not sure, and 73 (23.47%) thought their disease was not cancer. These data suggest that the majority of cancer patients attending our outpatient oncology unit are being correctly informed about their diagnosis. In our series the type of tumor had an important impact on diagnosis disclosure, while age and educational status did not.

Changes in interleukin-6 and IGF system and their relationships in placenta and cord blood in newborns with fetal growth restriction compared with controls.

OBJECTIVES: The IGF system is central to fetal growth. Recently, the relationships between cytokines and the IGF system have been shown in specific tissues. It is unknown whether these occur in the placenta. The aim of this study was to assess whether interleukin-6 (IL-6) modulated the IGF system. METHODS: Whole villous tissue and cord serum were collected from fetal growth restriction (FGR) neonates diagnosed before birth with altered Doppler velocimetry and controls. Sixteen FGR and 20 controls, born after week 32 of gestation from elective Caesarean sections, were compared. Total RNA was extracted from the placenta samples, reverse transcribed, and real-time quantitative reverse transcriptase (RT)-PCR was performed to quantify cDNA for IGF-I, IGF-II, IGF binding protein (IGFBP)-1, IGFBP-2, and IL-6. The same proteins were assayed in placenta lysates and cord serum using specific commercial kits and western immunoblotting. RESULTS: FGR subjects had significantly more IGFBPs-1 and -2, and IL-6 mRNA and corresponding proteins in the placenta. In particular, the less phosphorylated isoforms of IGFBP-1 were highly increased. IL-6 and IGFBPs-2 mRNA, and IL-6 and IGFBP-1 peptides were positively and significantly correlated in the placenta. The IGF-II peptide was also significantly increased in FGR placentas. In cord serum, IGFBPs-1 and -2 were significantly more elevated in the FGR neonates. Serum IL-6 was significantly and positively correlated with both IGFBP-1 and IGFBP-2. CONCLUSIONS: The placenta of FGR neonates has higher IGF-II, IGFBP-1, IGFBP-2, and IL-6 contents compared with controls. At birth, IGFBPs-1 and -2 are increased in the cord blood of FGR neonates. IL-6 and IGFBP-2 gene expressions are closely related in the placenta. We suggest that the increase in IL-6 and IGFBP-2 could be subsequent to hypoxia and nutrient deficiency. As IGFBP-2 has a strong affinity for IGF-II, which is crucial for fetal growth, it could be an important bioregulator of IGF-II in the placenta.

Association of HLA-DRB1*0401 allele with chronic pancreatitis.

INTRODUCTION: Chronic pancreatitis (CP) is characterized by irreversible morphologic and functional alterations of the pancreas, clinically presenting with upper abdominal pain as well as exocrine and endocrine insufficiencies. According to a more recent hypothesis, the pathogenesis may involve genetic and immunologic factors. AIM: To investigate the major histocompatibility complex (MHC) genes as a genetic background of chronic pancreatitis. METHODOLOGY: Allelic polymorphisms were investigated in the genes of the MHC region (HLA B, DRB, DQB) with PCR-based methodologies (PCR-SSP) in 56 patients with CP (44 males and 12 females) and 183 normal controls (78 males and 105 females) of the same ethnic group. All patients and controls gave their informed consent. RESULTS: Among HLA-DRB1 genes, DRB1*04 was significantly higher in CP patients than in controls (26.78% versus 8.1%; pc < 0.003; OR = 4.1; CI = 1.85-9.06). DRB1*04 allele specificities in the DRB1*04-positive patients demonstrated significantly higher frequencies of DRB1*0401 allele (14.3% versus 1.1%; p = 0.00017; OR = 15.08; CI = 3.1-73.36). Neither HLA-B nor HLA-DQB1 associations with the disease were found. CONCLUSIONS: This study supports a role of HLA-DRB1*0401 as a susceptibility factor for patients with CP. HLA DRB1*0401 contains the 70QKRAA74 amino acid sequence, which is also expressed by several human pathogens, including Epstein-Barr virus. T cells may be triggered in the pancreatic tissue upon exposure to foreign peptides similar enough to cross-react and to break immunologic tolerance.
