First Breast Cancer Mammography Screening Program in Mexico: Initial Results 2005–2006

Abstract:  Breast cancer is the most frequent malignant neoplasia worldwide. In emergent countries as Mexico, an increase has been shown in frequency and mortality, unfortunately, most cases in advanced loco-regional stages developed in young women. The success of breast screening in mortality reduction has been observed since 1995 in Western Europe and the United States, where as many as 40% mortality reduction has been achieved. Most countries guidelines recommends an annual or biannual mammography for all women >40 years of age. In 2005, FUCAM, a nonlucrative civil foundation in Mexico join with Mexico City government, initiated the first voluntary mammography screening program for women >40 years of age residing in Mexico City's Federal District. Mammographies were carried out with analogical mammographs in specially designed mobile units and were performed in the area of women's domiciles. This report includes data from the first 96,828 mammographies performed between March 2005 and December 2006. There were 1% of mammographies in Breast Imaging Reporting and Data System 0, 4, or 5 and 208 out of 949 women with abnormal mammographies (27.7%) had breast cancer, a rate of 2.1‰, most of them in situ or stage I (29.4%) or stage II (42.2%) nevertheless 21% of those women with abnormal mammography did not present for further clinical and radiologic evaluation despite being personally notified at their home addresses. The breast cancer rate of Mexican women submitted to screening mammography is lower than in European or North American women. Family history of breast cancer, nulliparity, absence of breast feeding, and increasing age are factors that increase the risk of breast cancer. Most cancers were diagnosed in women's age below 60 years (68.5%) with a mean age of 53.55 corroborating previous data published. It is mandatory to sensitize and educate our population with regard to accepting to visit the Specialized Breast Centers.     

Fertility concerns among breast cancer patients in Mexico

ObjectiveYoung women represent a high proportion of the total number of breast cancer (BC) patients in Mexico; however, no previous studies addressing their attitudes regarding the risk of chemotherapy-induced infertility and its contributing factors are available. The aim of this study was to evaluate the concerns of young women with BC towards the risk of infertility in two referral centers in Mexico with access to public health services.MethodsA cross-sectional study including women with newly or previously detected BC aged 40 years or younger at diagnosis was conducted. Variables regarding concerns about fertility were collected from an adapted version of the Fertility Issues Survey.Results134 consecutive eligible women responded to the in-person paper survey. 55% were partnered, 35.1% had no children, and 48% reported willingness to have children prior to BC diagnosis. Only 3% of patients considered to be able to afford extra expenses. At diagnosis, 44% of women expressed some level of concern about infertility risk. The only factor significantly associated with fertility concern was the desire of having children prior to diagnosis (OR 11.83, p = 0.006). Only 30.6% patients recalled having received information regarding infertility risk from their physicians.ConclusionA minority of young women with breast cancer in Mexico is informed about the risk of BC treatment-induced infertility, despite substantial interest. Informing all patients about infertility risk and available options for fertility preservation should be an essential aspect of the supportive care of young women with BC, even in low-middle income countries such as Mexico.     

Changing patterns in the management of locally advanced breast cancer: a preliminary report

Over the 8 years from 1976 to 1983, 28 patients with stage IIIB (T4a,b,c, NX-2, M0) and inflammatory breast cancers without evidence of disseminated disease at the time of diagnosis were treated at Ellis Fischel State Cancer Center in Columbia, Mo. This group comprised 4% of all cases of primary breast cancer seen during that period. Radiotherapy was the primary treatment in one half of the group during the first 4 years of the study (group A). Since 1981, locally advanced breast cancer has been treated by multidrug chemotherapy followed primarily by mastectomy (group B). The rate of local control was the same for both groups (78%). However, the median survival for group A was 11 months, only one patient being alive 5 years after diagnosis, whereas in group B, 12 of 14 patients were alive and clinically free of disease 9 to 31 months after diagnosis with a median follow-up of 16.5 months. This preliminary report confirms recent findings, supporting the use of polychemotherapy followed by mastectomy in the management of patients with locally advanced breast cancer.     

Diagnostic delays in laryngeal carcinoma: professional diagnostic delay is a strong independent predictor of survival

BACKGROUND: Clinical stage at the time of diagnosis is the most important determinant of prognosis in cancers of the head and neck. Accordingly, delay in diagnosis could worsen survival in laryngeal cancer, although this hypothesis has not been verified in previous studies. METHODS: To determine the effects of patient and professional diagnostic delays on survival in patients with laryngeal squamous cell carcinoma (LSCC), a population-based sample of 66 patients with LSCC in Northern Finland between 1990 and 1995 was investigated. In addition to clinical data from tertiary care units and mortality data from the national death register, we collected data about the first medical visit in primary care that resulted, subsequently, in the diagnosis of malignancy. RESULTS: Long professional delay in diagnosis (>or=12 months) was an independent and statistically significant determinant of worsened prognosis (adjusted relative hazard of death 4.74, p =.05). There was no correlation between patient delay and prognosis. Another significant factor related to impaired prognosis was advanced stage (IV vs I-III, adjusted relative hazard of death 5.18, p =.02). Long professional delay was not significantly related to any of the demographic or clinical characteristics. CONCLUSIONS: A long professional delay is a marked and independent determinant of impaired survival in laryngeal carcinoma and equals the effect of advanced stage. However, unlike in most other cancers, early symptoms and slow tumor growth give the physician a fairly long time to reach the correct diagnosis before the delay turns out to be fatal.     

Association between mode of breast cancer detection and diagnosis delay

We investigated the association between mode of breast cancer (Bca) detection and diagnosis delay in a case-series of primary, histologically confirmed Bca patients from Southern Italy.Nine hundred and fifty nine women diagnosed with incident, primary Bca were recruited in two southern Italian regions. We grouped the mode of detection into two categories: Self-Detection (S-D) and Mammography (MG). Diagnosis delay was defined as the time between detection and a histologically confirmed diagnosis of invasive Bca.20.9% detected Bca with MG while 79.1% had S-D Bca. Women who detected Bca themselves (S-D) were more likely to delay breast cancer diagnosis than women who were diagnosed by a mammography (MG) (OR: 2.0; 95% CI: 1.39–2.87); when considering the model adjusted for health system-related characteristics, the risk increased (OR: 2.13; 95% CI: 1.47–3.09).Our study indicates a disadvantage in terms of diagnostic delay for women who were admitted and treated in community hospitals compared to women admitted and treated in breast health services.     

Does open-access mammography and ultrasound delay the diagnosis of breast cancer?

There is a consensus that open-access breast imaging for general practitioners is inappropriate since the process omits an expert clinical examination and fine needle aspiration cytology. However, it was decided to test this hypothesis by comparing the outcome of breast referrals in a district with both an open-access imaging and a one-stop clinic. The time from referral to definitive diagnosis in all women with breast cancer was compared over a 12 month period in 1996. Of 1049 women referred for open-access imaging 20 (2%) were found to have breast cancer compared with 91 (9%) of 995 women referred to the one-stop breast clinic. There was a longer interval before the diagnosis of breast cancer was made in cases referred for open-access imaging compared with cases referred to the one-stop breast clinic (mean 63 vs 35 days). However, if patients with advanced disease are excluded the mean interval was 63 vs 44 days. The mean tumour size of breast cancers in cases referred to open-access imaging was smaller (1.5 vs 2.3 cm), there were fewer grade 3 tumours (10% vs 39%), and there was a lower rate of axillary lymph node metastases (20% vs 32%) compared with cases referred to the one-stop breast clinic. The longer interval for the open-access patients was largely due to administrative delay and the 3 patients with a delay of more than 3 months had all had a triple assessment which was false negative. This study does not support the hypothesis that open-access mammography is unsafe and should be withdrawn.     

Is Pregnancy After Breast Cancer Safe?

Abstract: The impact of treatment on subsequent fertility and the safety of childbearing are major complicating factors for young women diagnosed with breast cancer. As national data indicate women are postponing first pregnancy to older ages; therefore, many young patients are seeking clinical guidance regarding the safety of conception and treatment options that may not prevent subsequent pregnancy. Newly developed chemotherapy protocols of brief duration have improved life expectancy enabling some women to consider childbearing. This study was conducted to compare prognosis among breast cancer patients with and without a subsequent pregnancy. Medical record review of female members of a Northern California prepaid health care plan enabled the identification of 107 women with one or more subsequent pregnancies and 344 cases without a pregnancy, who were diagnosed between 1968 and 1995. Sets were matched on age, year and stage at diagnosis, months of survival and recurrence status at conception. Among the matched sets, neither risk of recurrence nor death differed significantly by subsequent pregnancy history during an average 12 years of follow‐up (adjusted hazard ratio [HR] recurrence: 1.2 [0.8, 2.0]; adjusted HR death: 1.0 [0.6, 1.9]). Women interested in preserving their fertility and considering pregnancy are a self‐selected population; therefore, to reduce potential bias, cases were matched on recurrence status at time of conception. Although the number of cases was limited, subgroup analyzes indicated a small, nonsignificant adverse effect among women who conceived within 12 months of diagnosis. This analysis of carefully matched cases provides reassurance that long‐term prognosis was not adversely affected by subsequent pregnancy.     

Surgical treatment of young women with breast cancer: Public vs private hospitals

Disparities in breast cancer treatment have been documented in young and underserved women. This study aimed to determine whether surgical disparities exist among young breast cancer patients by comparing cancer treatment at a public safety‐net hospital (BH) and private cancer center (PCC) within a single institution. This was a retrospective study of young women (<45) diagnosed with invasive breast cancer (stage I‐III) from 2011‐2016. Patient information was abstracted from the breast cancer database at BH and PCC. Demographic variables, surgery type, method of presentation, and stage were analyzed using Pearson's chi‐square tests and binary logistic regression. A total of 275 patients between ages 25‐45 with invasive breast cancer (Stage I‐III) were included in the study. There were 69 patients from BH and 206 patients from PCC. At PCC, the majority of patients were Caucasian (68%), followed by Asian (11%), Hispanic (10%), and African American (8.7%). At BH, patients were mostly Hispanic (47.8%), followed by Asian (27.5%), and African American (10.1%). At PCC, 82% had a college/graduate degree versus 18.6% of patients at BH (P < 0.001). All patients at PCC reported English as their primary language versus 30% of patients at BH (P < 0.001). Patients at PCC were more likely to present with lower stage cancer (P = 0.04), and less likely to present with a palpable mass (P = 0.04). Hospital type was not a predictor of receipt of mastectomy (P = 0.5), nor was race, primary language, or education level. Of patients who received a mastectomy, 87% at BH and 76% at PCC had immediate reconstruction. Surgical management of young women with breast cancer in a public hospital versus private hospital setting was equivalent, even after controlling for race, primary language, stage, and education level.     

Diagnostic delay in breast cancer

BACKGROUND: Delay in the diagnosis of breast cancer has important clinical and medicolegal implications. This study assessed the frequency, causes and effects of delay in the diagnosis of breast cancer in a specialist breast unit. METHODS: Details of women who attended the breast clinic between 1988 and 1999 inclusive, and for whom the interval between first attendance and diagnosis of invasive breast cancer was greater than 2 months, were reviewed. Potential causes of delay were identified and the consequence of the delay assessed. The clinical features were compared with those of patients diagnosed with breast cancer during a 2-year period from 1999 and 2001. RESULTS: Breast cancer was diagnosed in 5283 women during the interval reviewed; delay in diagnosis was suggested in 72 women (1.4 per cent). Women with a delayed diagnosis were younger (P < 0.001) and had a smaller tumour at diagnosis (P = 0.011) compared with all women diagnosed with breast cancer between 1999 and 2001. There were no differences in the rate of axillary node positivity or the need for mastectomy. Women unsuitable for conservation therapy in the delayed group had a significantly longer interval to diagnosis (P = 0.006). CONCLUSION: The likelihood that conservation therapy will be appropriate is reduced when the hospital delay in the diagnosis of breast cancer is more than 240 days. All patients with a palpable mass require triple assessment to minimize delay in diagnosis of breast cancer.

Delay in diagnosis of breast cancer.

OBJECTIVES: To assess the consequences of physician delay in the diagnosis of breast cancer by comparing stage, treatment, and outcome of patients with and without delay, and to identify patient characteristics that may make diagnosis more difficult. SUMMARY BACKGROUND INFORMATION: Delay in diagnosis of breast cancer is the most common clinical scenario resulting in malpractice litigation. METHODS: The records of 1014 patients were reviewed and the events preceding the diagnosis were reconstructed. Accurate assessment of the physician delay in diagnosis could be made for 606 patients, 51 (8%) with physician delay >3 months. Patients with delay were comparable to patients without delay in terms of age, height, weight, age at menarche, pregnancies, children, proportion in menopause, age at menopause, and family history of breast cancer. RESULTS: Thirty-six percent of patients who had a delay in diagnosis had normal mammograms versus 7% of patients without delay. Cancers in patients with delay were significantly larger on average than in those without delay, but there were no significant differences in pathology, differentiation, nodal status, TNM stage, treatment, or outcome. CONCLUSIONS: Physician delay in the diagnosis of breast cancer is common, and patients with delay are similar to patients without delay, although they are more likely to have normal mammograms. The consequences of physician delay in terms of stage at diagnosis, treatment, and outcome were not statistically significant.     

Prognostic influence of pregnancy before, around, and after diagnosis of breast cancer

A woman's risk of developing breast cancer is closely related to reproductive factors. Whereas the etiological importance of reproductive factors is well described, less is known about the prognostic influence of these factors. The prognostic effect of childbearing before, around, and after diagnosis is reviewed based on the literature and on studies from Danish Breast Cancer Cooperative Group, DBCG. In women with breast cancer overall number of childbirths is found to be without prognostic importance. Women with early primary childbirth seem to have an inferior prognosis compared to women who postpone childbearing. It is generally accepted that early first childbirth is associated with reduced risk of developing breast cancer. Thus, it is proposed that women who develop breast cancer despite an early first delivery represent a selected group of patients with particularly aggressive disease. Women diagnosed with breast cancer during pregnancy often present with advanced disease, but pregnancy at time of diagnosis does not seem to be an independent prognostic factor. However, women diagnosed with breast cancer in the first years after childbirth have a significantly reduced survival. It is assumed that these women, due to the physiological changes during pregnancy, experience growth induction of the tumours during the preclinical stage.In contrast, there is no evidence that pregnancy after breast cancer treatment has a negative influence on prognosis.     

Diagnostic delay of breast cancer – An analysis of claims to Swedish Board of Malpractice (LÖF)

Aim

Delay in the diagnosis of breast cancer may have important clinical and medico-legal implications. This study examined the decisions made by reviewers at the Swedish agency (LÖF) that handles claims of medical malpractice where claimants seek compensation for alleged suffering and/or negative clinical impacts of diagnostic delays.

Material and methods

In 1995–2006 a total of 134 women filed claims for negative effects resulting from delays in the diagnosis of breast cancer. Review of the claims led to approval of delay in the primary diagnosis for 62 women and of recurrence for 28 women. The clinical symptoms that were overlooked and other causes of delay that had any relation to therapy, prognosis and economic compensation were identified. The verdicts reached were analysed.

Results

The median delay in the diagnosis of the primary disease was 11 months and for recurrent disease 3.5 months. Delay in diagnosis of the primary disease was considered to have an impact on the therapy in 23%. The prognosis was postulated to have been adversely affected 11% of the patients for whom the delay was longer than 12 months. Delay in diagnosing the recurrence was contributing to delay in starting therapy and to unnecessary suffering in 32%. The delay in diagnosis was mainly caused by incomplete clinical or radiological examination and by misinterpretations of the examination results. Economic compensation was given in 90%. There was a warning or admonition to the responsible doctor in a third of the cases referred to the judgement court.

Conclusion

This study demonstrates that claims for compensation for delay in diagnosis of breast cancer in Sweden occur in about 1/1000 new patient. The delay in the diagnosis of the primary tumour was considered to have an impact on the magnitude of therapeutic measures in almost 25% of the women who filed claims. Economic compensation for the patients’ injuries was given in ninety percent of the cases. In women for whom there was a delay in diagnosing the recurrence there was consequently a delay in starting the palliative therapy.     

Age-related differences in breast cancer stage at diagnosis between black and white patients in an urban community hospital

Background: Breast cancer mortality is significantly higher among black patients compared to white patients. Black women are reportedly at increased risk for early-onset breast cancer. Our goal was to evaluate stage distribution relative to age among black and white breast cancer patients in an institution with a relatively high minority patient population. Methods: We evaluated 425 patients diagnosed with breast cancer between 1990 and 1994: 56% white, 34% black, the remainder were other ethnicities. Patients were stratified by age: under 50 years versus 50 and older. Socioeconomic status was estimated by utilization of medical care in the private-practice setting versus the public clinic. Results: Significantly more black patients were younger at diagnosis compared to white patients (32% vs. 20%; p=0.008). There was a significantly more advanced stage distribution among the younger black patients, but not among the older black patients. Most of the black and white patients received private-practice care. Conclusions: These age-related differences in breast cancer stage distribution between black and white patients (which appeared independent of socioeconomic status) indicate that more aggressive screening and public education progams directed toward younger black women is warranted, and they lend support to the possibility of ethnicity-related variation in primary tumor biology.     

Breast cancer and pregnancy

Pregnancy-associated breast cancer has an overall worse prognosis than nonpregnancy-associated breast cancers because a large proportion present with more advanced disease. Stage for stage, however, the prognosis is similar. The various modalities used for screening, diagnosis, and staging of breast cancer are not always applicable during pregnancy. Often, a delay in diagnosis may contribute to a more advanced stage at presentation. The management of pregnant women with breast cancer is also different because it involves assessing the possible risks to the fetus versus the maternal benefits.     

Prognostic significance of synchronous and metachronous bilateral breast cancer

Women previously treated for primary operable breast cancer are at increased risk of developing cancer in the contralateral breast, but the clinical significance of this development is unclear. The purpose of this study was to assess the impact of synchronous bilateral breast cancer or the development of a metachronous contralateral breast primary on the prognosis. In a series of 3210 women age < or = 70 years treated between 1975 and 1995 for primary operable breast cancer, 106 were identified to have bilateral breast cancer. Of these women, 26 were noted to have synchronous bilateral breast primaries (0.8%), and 80 developed a contralateral breast cancer after treatment for an initial primary breast cancer. Using life-tables analysis, there was a significant difference in survival between women with unilateral breast cancer, those with synchronous bilateral breast cancers, and those with metachronous contralateral breast with survivals at 16 years of 53.8%, 42.4%, and 60.1%, respectively (p < 0.0001), from the date of the diagnosis of the first primary tumor. There was no difference in survival seen between the three groups when survival was calculated from the date of diagnosis of the second primary in cases of metachronous contralateral breast cancer (p = 0.31). When contralateral breast cancer was incorporated as a time-dependent covariate in a Cox multivariate model together with the three factors used to determine the Nottingham Prognostic Index (invasive tumor size, grade, and lymph node stage), contralateral breast cancer continued to be a significant prognostic determinant (p = 0.02). The survival of women with synchronous bilateral breast cancer or metachronous breast cancers diagnosed within 2 years of the original primary was worse than those with unilateral disease. However, the time duration to metachronous contralateral breast cancer did not have prognostic significance in a multivariate model compared with the prognostic features of the original primary.     

Geographical differences in risk of advanced breast cancer: Limited evidence for reductions over time,Queensland, Australia 1997–2014

BackgroundReducing geographical inequalities in breast cancer stage remains a key focus of public health policy. We explored whether patterns of advanced breast cancer by residential accessibility and disadvantage in Queensland, Australia, have changed over time.MethodsPopulation-based cancer registry study of 38,706 women aged at least 30 years diagnosed with a first primary invasive breast cancer of known stage between 1997 and 2014. Multilevel logistic regression was used to examine temporal changes in associations of area-level factors with odds of advanced disease after adjustment for individual-level factors.ResultsOverall 19,401 (50%) women had advanced breast cancer. Women from the most disadvantaged areas had higher adjusted odds (OR = 1.23 [95%CI 1.13, 1.32]) of advanced disease than those from least disadvantaged areas, with no evidence this association had changed over time (interaction p = 0.197). Living in less accessible areas independently increased the adjusted odds (OR = 1.18 [1.09, 1.28]) of advanced disease, with some evidence that the geographical inequality had reduced over time (p = 0.045). Sensitivity analyses for un-staged cases showed that the original associations remained, regardless of assumptions made about the true stage distribution.ConclusionsBoth geographical and residential socioeconomic inequalities in advanced stage diagnoses persist, potentially reflecting barriers in accessing diagnostic services. Given the role of screening mammography in early detection of breast cancer, the lack of population-based data on private screening limits our ability to determine overall participation rates by residential characteristics. Without such data, the efficacy of strategies to reduce inequalities in breast cancer stage will remain compromised.     

Causes of late diagnosis in cases of colorectal cancer seen in a district general hospital over a 2-year period.

Our aim in this prospective study was to identify those patients who were found to have a colorectal cancer after a delay we considered unacceptable; this was taken as 6 months or more from initial presentation to a physician to diagnosis. It was then possible to determine the presenting complaints (always multiple) and the reasons for delay, in the hope that recommendations could be made regarding appropriate, rapid and thorough investigation of patients suspected of having a colorectal cancer. Of the total of 141 patients with colorectal cancer (108 elective, 33 emergency cases) under the care of one consultant during the period studied, 17 patients (12%) (10 men and 7 women), satisfied the criteria for late diagnosis. The mean age was 72.4 years (range 43-86 years). Five common presenting complaints were identified. They were, symptomatic iron deficiency anaemia, rectal bleeding, change in bowel habit, abdominal pain and weight loss. Incomplete imaging of the colon in patients with sinister presenting symptoms was the most commonly identified factor in delay of diagnosis. Inappropriate iron therapy and false-negative reporting of double contrast barium enema investigations were both seen in a number of cases. Other causes were, inappropriate surgical treatment and both clerical error and delay. The mean time for delay was 17.6 months (median 15 months). Late diagnosed cancers were most commonly found in the caecum and least commonly in the rectum. Colonic tumours of each Dukes' stage were identified, Dukes' B most common and Dukes' A least.
