Follow ups after breast cancer diagnosis is usual practice, but there is no agreed consensus among breast care providers on frequency or duration of follow up after diagnosis and adjuvant treatment. The aim of this study is to find out women’s views on the period of the clinical follow up after breast cancer diagnosis. Method: This was a surveillance study in Greenock and Glasgow in the UK (Between September 2009 and December 2010). The study group comprised of 446 Women, 246 with the history of breast cancer diagnosed 1 - 10 years, (median 4.2 years) were asked to complete a questionnaire about their views of preferred duration of follow up while they were waiting for the annual review at a breast clinic, the same questionnaire was completed by 200 women with no history of breast cancer. Results: Between September 2009 and December 2010, 246 patients were included in the study. 40% of patients were within the first three years of follow up, 27% between the 4th and 6th year and 33% were in follow-up for more than 6 years. 63% of cancer survivors think that, 10 years of follow up is necessary for reassurance, detection and treatment of any new, recurrent or spread of their breast cancer. 14% and 22% of women with a history of breast cancer preferred 3 and 5 years review by trained Radiologist/GP respectively. Women without a history of breast cancer were different in their thoughts about follow up after breast cancer: 10%, 25%, and 30% chosen 10, 5 and 3 years, 35% preferred don’t know the answer. Conclusion: Follow up programs for breast cancer survivors need to be organized, evidence based, flexible and patient tailored. Patients’ views should be taken into account when considering provision of follow-up care for breast cancer patients.展开更多

Methods: 763 patients treated for breast cancer between February 1953 and September 1976, were followed up until December 2014. They were divided into two cohorts;earlier cohort exclusively underwent radical mastectomy plus adjuvant radiotherapy, while later cohort had radical mastectomy alone. Assuming that in all patients follow-up was terminated at 50 or 25 years after diagnosis, likelihood ratio test and stratified Log-rank tests were performed to evaluate the differences in cure rate and overall survival between the two cohorts. Results: During the 50 years, radical mastectomy alone compared with radical mastectomy plus adjuvant radiotherapy is associated with a significantly higher cure rate, and higher survivals regardless of whether the death was from breast cancer, second cancer, benign causes or any causes. However, if follow-up information is limited to 25 years, the advantage of radical mastectomy alone is partly offset and the survival difference between the two cohorts becomes less significant. Conclusion: Radiotherapy to breast cancer may adversely affect not only mortality from breast cancer, but mortalities unrelated to breast cancer. Since such deaths occur later, they may fail to be detected unless follow-up is long enough. Thus, deleterious effects of radiotherapy may be underestimated. Exceedingly long follow-up is required to accurately estimate the cure rate and the long-term effect of radiotherapy.展开更多

The aim of this study is to investigate the accuracy of sonography in the diagnosis of loco-regional lymphatic recurrences in comparison to the core needle biopsy results. Materials and Methods: Among 6455 patients who were followed up with clinical examination, mammography and ultrasound between January 2004 and November 2011, 125 (1.93%) patients had to be investigated with a core needle biopsy of a sonographically suspicious loco-regional lymph node. Results: Among the whole series, a total of 142 ultrasound-guided core needle biopsies were performed. Follow-up for the primary tumor lasted for a median time of 6.1 years (range 1 - 27 years). Ultrasound of suspicious loco-regional lymph nodes showed a sensitivity of 89.5%, a specificity of 87.1% and a positive predictive value of 89.5%. Conclusions: In our experience, ultrasound of suspicious loco-regional lymph nodes showed good accuracy and it should be a part of the standard examinations performed during follow-up for breast cancer.展开更多

Breast cancer diagnosis being a stressful experience, causes psychological and emotional disruption that can be abated by meeting information needs of the affected patients. In light of the escalating cases of Breast cancer among the Zambian women, the study examined a special aspect of cancer management which is usually neglected in most cases. Aim: The main objective of the study was to assess information needs of breast cancer patients at the Cancer Diseases Hospital in Lusaka, Zambia using a modified structured interview schedule adopted from the Toronto Information Needs Questionnaire-Breast Cancer (TINQ-BC). Methods: A descriptive cross-sectional design was used to elicit the information needs of breast cancer patients. One hundred and ten (97% response rate) participants were selected using simple random sampling method and data was collected using a modified structured interview schedule adopted from the Toronto Information Needs Questionnaire-Breast Cancer (TINQ-BC). Stata 10.0 (StataCorp, 2008) was employed for all quantitative data analysis and graphical presentation of data. Results: The overall score for information needs was obtained by adding the scores across all the five information needs categories which were further divided into three categories namely: low important scores, of less than 50%, moderately important scores of 50% - 70% and highly important scores ranged above 70% of the 200 total scores. Out of the 110 participants recruited, 88 (80%) indicated that the information across the five categories was moderately important. Logistic regression of information needs and posited determinants revealed that anxiety levels;education level;presence of co-morbidity;and being on treatment were significant determinants of patients’ informational needs (Effect’s p ≤ 0.05). Conclusion: The findings of this study support the idea that breast cancer patients are seeking more information on their illness, hence information provision is one of the most important factors for providing high quality cancer care across the whole cancer continuum. Therefore, appreciating the information needs of breast cancer patients is substantial in improving care.展开更多

With few treatment options to choose from, such patients often benefit from empathic support and access to information to help them make treatment decisions based on their individual circumstances and needs. Patients with MBC have been shown to present with unique physical, social and psychological needs that require additional time, counselling and availability of health care providers in addition to the routine options available to other patients. In resource-limited settings, the needs of such patients are often unknown and unaddressed, which adds to the anxiety associated with the diagnosis and its treatment. Materials and methods: This descriptive qualitative study was conducted using 3 focus group discussions with a total of 17 participants with metastatic breast cancer (MBC) attending Ocean Road Cancer Institute in Dar es Salaam, Tanzania. Participants were purposively selected for the study from outpatient clinics and inpatient wards. A semi-structured FGD guide was used to moderate discussions and analysis was done using a thematic approach. Results: The median age of participants was 51 (range 33 - 81 years) with an average of 4 months (range 1 - 12 months) from diagnosis of BC to the interview. 4 (24%) were diagnosed with MBC on first presentation (denovo). Participants spoke about the importance of accurate BC-related information in allowing timely referral and treatment both in the community and within the health system. They recognized the role of mass and social media in increasing awareness about BC and identified myths surrounding cancer treatment especially mastectomy. Correct and timely information at points of care, through media platforms and via ambassadors/patient support groups was perceived as a means to avoiding delays and securing early and effective treatment. Conclusion: Patients with MBC in Tanzania have many unmet informational needs in relation to their disease. Accurate BC-related information is important in allowing early detection and diagnosis. At the community level, provision of information through established media platforms and the use of patient advocates may help to enable early referral and treatment of patients.展开更多

Into daily clinical practice some controversies are occurred. Especially, in the diagnosis field, despite the fact that the optimal age in which screening mammography should start is a subject of intense controversy, there is a shift toward the beginning at the age of 40 although it is suggested that the net benefit is small for women aged 40 to 49 years. In addition, a promising tool in BC screening seems to be breast tomosynthesis. Other tools such as 3D ultrasound and shear wave elastography(SWE) are full of optimism in BC screening although ultrasonography is not yet a first-line screening method and there is insufficient evidence to recommend the systemic use of the SWE for BC screening. As for breast magnetic resonance imaging(MRI), even if it is useful in BC detection in women who have a strong family history of BC, it is not generally recommended as a screening tool. Moreover, based on the lack of randomized clinical trials showing a benefit of presurgical breast MRI in overall survival, it's integration into breast surgical operations remainsdebatable. Interestingly, in contrast to fine needle aspiration, core biopsy has gained popularity in presurgical diagnosis. Furthermore, after conservative surgery in patients with positive sentinel lymph nodes, the recent tendency is the shift from axillary dissection to axillary conserving strategies. While the accuracy of sentinel lymph node after neoadjuvant chemotherapy and second BC surgery remains controversial, more time is needed for evaluation and for determining the optimal interval between the two surgeries. Additionally, in the decision between immediate or delayed breast reconstruction, there is a tendency in the immediate use. In the prevention of BC, the controversial issue between tamoxifen and raloxifene becomes clear with raloxifene be more profitable through the toxicities of tamoxifen. However, the prevention of bone metastasis with bisphosphonates is still conflicting. Last but not least, in the follow-up of BC survivors, mammography, history and physical examination are the means of an early detection of BC recurrence.展开更多

The aims of this study were to determine the level of awareness of women on the performance of mammography in the diagnosis and screening for breast cancer. This was a cross-sectional study over a period of 4 months (from October 1, 2016 to January 31, 2017) in Togo. It consisted in completing a questionnaire distributed to women above 30 years of age. The mean age of the women was 42 years. 88.8% of them had heard of breast cancer. There was a link between age, occupation, level of education and awareness of breast cancer. Only 20.8% of women had heard of mammography, with a link between awareness of mammography and age, occupation, and level of education. A link was noted between awareness of breast cancer and awareness of mammography. Information on mammographic breast cancer screening is inadequate in Togo.展开更多

Nevertheless, the psychological intervention is also important. The systematic consultation implemented in our hospital after a diagnosis of cancer is a manner to answer patients’ psychological needs. In a survey, we assessed the satisfaction and expectations of the patients about this consultation. Methods: One year after a diagnosis of breast cancer, 104 patients answered a retrospective questionnaire assessing: socio- demographic data, cancer medical information, systematic consultation satisfaction, patients’ expectations for a systematic intervention, and patients’ characteristics who began a psychological follow-up. Results: 72.1% of the patients were satisfied with having the opportunity to consult a psychologist during a systematic consultation after cancer diagnosis. Their expectations were to have opportunities of emotional expression, reassurance, obtaining additional medical information, talking about their fear over additional treatments, and identifying further support. 28.8% of the patients re-contacted the psychologist for further help after the systematic consultation. They were significantly younger (p < 0.001) than the others. Conclusions: Besides the importance of support by medical specialists [1], offering the opportunity to breast cancer patients to discuss inner feelings and treatment expectations during a systematic psychological consultation was useful for most of them. About one third of the patients asked for a further consultation with a psychologist after a first systematic consultation, especially younger patients. This stressed the importance of the role of psychologists for psycho-social support of the patient after cancer treatment.展开更多

They were significantly younger (p < 0.001) than the others. Conclusions: Besides the importance of support by medical specialists [1], offering the opportunity to breast cancer patients to discuss inner feelings and treatment expectations during a systematic psychological consultation was useful for most of them. About one third of the patients asked for a further consultation with a psychologist after a first systematic consultation, especially younger patients. This stressed the importance of the role of psychologists for psycho-social support of the patient after cancer treatment.
