ABSTRACT

BACKGROUND: The invasion of Ukraine by Russia in February 2022 has resulted in destruction of healthcare infrastructure and triggered the largest wave of internally displaced populations and refugees since World War Two. Conflicts in transitioned countries such as Ukraine create new non-communicable disease (NCD) challenges, especially for cancer care for refugees and humanitarian assistance in host countries. In the early days, rapid attempts were made to model possible impacts. METHODS: By evaluating open source intelligence used in the first three months of the conflict through snowball search methods, we aimed to address: (i) burden of cancer in Ukrainian population, specifically considering translating to the refugees population, and its cancer care capacity; ii) baseline capacity/strengths of cancer systems in initial host countries. Moreover, using a baseline scenario based on crude cancer incidence in Ukraine, and considering data from UNHCR, we estimated how cancer cases would be distributed across host countries. Finally, a surveillance assessment instrument was created, intersecting health system's capacity and influx of internally displaced populations and refugees. FINDINGS AND CONCLUSIONS: The total new cancer patients per month in pre-conflict Ukraine was estimated as 13,106, of which < 1 % are paediatric cases. The estimated cancer cases in the refugee population (combining prevalent and incident), assuming 7.5 million refugees by July 2022 and a female:male ratio of 9:1, was 33,121 individuals (Poland: 19284; Hungary: 3484; Moldova: 2651; Slovakia: 2421; Romania: 5281). According to our assessments, Poland is the only neighbouring country classified as green/yellow for cancer capacity, i.e. sufficient ablility to absorb additional burden into national health system; Slovakia we graded as yellow, Hungary and Romania as yellow/red and Moldova as red.

ABSTRACT

OBJECTIVE: To evaluate facilitators and barriers influencing mammography screening participation among women. DESIGN: Mixed methods study. SETTING: Three hospital catchment areas in Hidalgo, Mexico. PARTICIPANTS: Four hundred and fifty-five women aged 40-69 years. INTERVENTION: Three hundred and eighty women completed a survey about knowledge, beliefs and perceptions about breast cancer screening, and 75 women participated in semi-structured, in-person interviews. Survey data were analyzed using logistic regression; semi-structured interviews were transcribed and analyzed using elements of the grounded theory method. MAIN OUTCOME MEASURE: Women were categorized as never having had mammography or having had at least one mammogram in the past. RESULTS: From survey data, having had a Pap in the past year was associated with ever having had breast screening (odds ratio = 2.15; 95% confidence interval 1.30-3.54). Compared with never-screened women, ever-screened women had better knowledge of Mexican recommendations for the frequency of mammography screening (49.5% vs 31.7% P < 0.001). A higher percentage of never-screened women perceived that a mammography was a painful procedure (44.5% vs 33.8%; P < 0.001) and feared receiving bad news (38.4% vs 22.2%; P < 0.001) compared with ever-screened women. Women who participated in semi-structured, in-person interviews expressed a lack of knowledge about Mexican standard mammographic screening recommendations for age for starting mammography and its recommended frequency. Women insured under the 'Opportunities' health insurance program said that they are referred to receive Pap tests and mammography. CONCLUSIONS: Local strategies to reduce mammogram-related pain and fear of bad news should work in tandem with national programs to increase access to screening.

ABSTRACT

Using oncoplastic surgical techniques for breast preservation, breast surgeons can achieve widened surgical margins at the same time that the shape and appearance of the breast is preserved and sometimes rejuvenated. Oncoplastic surgical resection is designed to follow the cancer's contour, which generally follows the segmental anatomy of the breast, which has been well understood since the mid 19th century because of pioneering anatomic studies performed by Sir Astley Paston Cooper. The quadrantectomy, developed by Veronesi and colleagues in the 1970's, follows these same anatomic principles of wide segmental resection. The more surgically narrow lumpectomy as popularized in the U.S. uses a smaller, scoop-like non-anatomic resection of cancer. With negative surgical margins, the lumpectomy is equivalent to the quadrantectomy in achieving the goals of breast conservation as measured by local recurrence and survival. However, the lumpectomy is less versatile for resection of larger cancers, and can be more prone to creating suboptimal cosmetic defects. Cancers with large in situ components can be particularly problematic for resection with the standard lumpectomy, when they extend both centrally toward the nipple and peripherally to distal terminal ductulo-lobular units, which typically occur in a pie-shaped segmental distribution. Ductal segments, each of which ultimately drains to a single major lactiferous sinus at the nipple, vary in size and depth in the breast. Breast surgeons should carefully evaluate the cancer distribution and extent in the breast before operation. A combination of imaging methods (mammography with magnification views, ultrasonography, magnetic resonance imaging [MRI], or all) may yield the best estimates of overall tumor extent. Multiple bracketing wires afford the greater help to complete surgical excision. Those tumors with segmental spreading are best excised by oncoplastic resections according to their distribution.

ABSTRACT

BACKGROUND: Breast cancer originates in breast epithelium and is associated with progressive molecular and morphologic changes. Women with atypical breast ductal epithelial cells have an increased relative risk of breast cancer. In this study, ductal lavage, a new procedure for collecting ductal cells with a microcatheter, was compared with nipple aspiration with regard to safety, tolerability, and the ability to detect abnormal breast epithelial cells. METHODS: Women at high risk for breast cancer who had nonsuspicious mammograms and clinical breast examinations underwent nipple aspiration followed by lavage of fluid-yielding ducts. All statistical tests were two-sided. RESULTS: The 507 women enrolled included 291 (57%) with a history of breast cancer and 199 (39%) with a 5-year Gail risk for breast cancer of 1.7% or more. Nipple aspirate fluid (NAF) samples were evaluated cytologically for 417 women, and ductal lavage samples were evaluated for 383 women. Adequate samples for diagnosis were collected from 111 (27%) and 299 (78%) women, respectively. A median of 13,500 epithelial cells per duct (range, 43-492,000 cells) was collected by ductal lavage compared with a median of 120 epithelial cells per breast (range, 10-74,300) collected by nipple aspiration. For ductal lavage, 92 (24%) subjects had abnormal cells that were mildly (17%) or markedly (6%) atypical or malignant (<1%). For NAF, corresponding percentages were 6%, 3%, and fewer than 1%. Ductal lavage detected abnormal intraductal breast cells 3.2 times more often than nipple aspiration (79 versus 25 breasts; McNemar's test, P<.001). No serious procedure-related adverse events were reported. CONCLUSIONS: Large numbers of ductal cells can be collected by ductal lavage to detect atypical cellular changes within the breast. Ductal lavage is a safe and well-tolerated procedure and is a more sensitive method of detecting cellular atypia than nipple aspiration.

ABSTRACT

BACKGROUND: Some patients undergoing axillary lymph node dissection (ALND) experience postoperative pain and limited range of motion associated with a palpable web of tissue extending from the axilla into the ipsilateral arm. The purpose of this study is to characterize the previously undescribed axillary web syndrome (AWS). METHODS: To identify patients with AWS, a retrospective review was performed of all invasive breast cancer patients treated by a single surgeon (REM) between 1980 and 1996. Records were also reviewed of 4 more recent patients who developed AWS after undergoing sentinel node lymph node dissection (SLND) without ALND. RESULTS: Among 750 sequentially treated patients, 44 (6%) developed AWS between 1 and 8 weeks after their axillary procedure. The palpable subcutaneous cords extended from the axillary crease down the ipsilateral arm, across the antecubital space, and in severe cases down to the base of the thumb. The web was associated with pain and limited shoulder abduction (< or = 90 degrees in 74% of patients). AWS resolved in all cases within 2 to 3 months. AWS also occurred after SLND. Tissue sampling of webs in 4 patients showed occlusion in lymphatic and venous channels. CONCLUSIONS: AWS is a self-limiting cause of morbidity in the early postoperative period. More limited axillary surgery, with less lymphovenous disruption, might reduce the severity and incidence of this syndrome, although SLND does not eliminate its occurrence.

ABSTRACT

BACKGROUND: Metastases to internal mammary lymph nodes (IMN) may occur in patients with breast cancer and may alter treatment recommendations. The purpose of this study was to identify the frequency of IMN drainage in patients undergoing breast lymphoscintigraphy and sentinel lymph node dissection (SLND). METHODS: The combined technique of peritumoral injection of radiocolloid and Lymphazurin blue for SLND was performed on 220 patients. All patients underwent preoperative lymphoscintigraphy before SLND. Lesion location by quadrant included: 110 upper outer (UOQ), 49 lower outer (LOQ), 30 upper inner (UIQ), 24 lower inner (LIQ), and 7 central. RESULTS: Drainage to any nodal basin was observed in 184 of 220 patients (84%). IMN drainage was documented in 37 of 220 (17%) of patients. IMN drainage without evidence of axillary drainage occurred in 2 of 220 patients(1%). Drainage to the IMN based on quadrant location of the lesion was as follows: UOQ, 10%; LOQ, 27%; UIQ, 17%; LIQ, 25%; and central, 29%. CONCLUSIONS: Internal mammary lymph node drainage shown by breast lymphoscintigraphy is common. Tumors in all quadrants may drain to IMNs, although drainage is significantly more common from quadrants other than the UOQ. Further studies are needed to determine whether lymphoscintigraphy drainage patterns identify patients at the highest risk for IMN metastases who may benefit from radiotherapy.

ABSTRACT

Prophylactic mastectomy reduces the likelihood of developing breast cancer among women at heightened risk for breast cancer, but at significant personal cost. Women at increased breast cancer risk on the basis of hormonal history, family history and/or genetic mutation carrier status may consider bilateral prophylactic mastectomy with or without reconstruction to reduce their cancer risk and/or decrease their chances of cancer mortality. Women having received mastectomy as treatment for breast cancer may request contralateral mastectomy to decrease the chances of developing a second breast primary. The potential oncologic value of these procedures must be weighed carefully on a case-by-case basis against the operation's physical and psychological morbidity. The purpose of this literature review is to provide a practice-oriented summary of recent clinical studies attempting to address the relative risks and benefits of preventive surgery for breast cancer. Data are included regarding the psychological factors surrounding patient selection and quality of life outcomes, which become the cornerstone of patient satisfaction and acceptance. Taken together, these data support the Society of Surgical Oncology position statement regarding the proper application of prophylactic surgery for breast cancer.

ABSTRACT

Surgical care has been the mainstay of breast cancer diagnosis and treatment. As care has evolved, increased collaborative approaches among surgeons, radiologists, radiation oncologists and medical oncologists have improved the quality of breast cancer treatment for the patient. Breast conservation therapy (BCT) exemplifies how multi-specialty care can increase cancer cure rates at the same time that the disfiguring aspects of breast cancer treatment can be minimized. New questions are being raised within clinical forums about how to do better both for the patient and for her oncologic treatment. The following questions represent three current issues in BCT: 1. What general operative approaches in BCT can minimize morbidity and optimize the cosmetic outcome from surgery? 2. What role does radiation therapy play in BCT for invasive and non-invasive breast cancer to supplement surgical intervention? 3. What role can neoadjuvant chemotherapy play in improving BCT rates?

ABSTRACT

BACKGROUND: In 1998, an unusually large number of invasive lobular breast carcinoma cases were seen at the University of Washington. The purpose of this study was to assess whether the incidence rate of invasive lobular carcinoma has been increasing disproportionately compared with the incidence rate of invasive ductal carcinoma. METHODS: Age specific and age-adjusted breast carcinoma incidence rates from 1977-1995 were obtained from the nine population-based cancer registries that participate in the Surveillance, Epidemiology, and End Results (SEER) program. Three histologic groupings were used: lobular, ductal, and all invasive breast carcinomas. Overall incidence rates for each grouping, as well as for each stage (local, regional, and distant), were obtained. RESULTS: The rate of incidence of lobular carcinoma increased steadily from 1977-1995 in women age >/= 50 years whereas it remained stable in women age < 50 years. Alternatively, the rate of incidence of ductal carcinoma increased steadily from 1977-1987, but from 1987-1995 it remained relatively constant across all age groups. CONCLUSIONS: The incidence rates of invasive lobular breast carcinomas increased steadily since 1977 whereas the incidence rates of invasive ductal carcinoma have plateaued since 1987. This rise occurred specifically among women age >/= 50 years and may be related to postmenopausal status. Further epidemiologic, clinical, and laboratory research is required to assess what factors are contributing to this trend.

ABSTRACT

BACKGROUND: Sentinel lymph node dissection (SLND) has been a promising new technique in breast carcinoma staging, but could be unreliable in certain patient subsets. The current study assessed whether age, preoperative chemotherapy, tumor size, and/or previous excisional biopsy influenced the identification of sentinel nodes (SLNs) or the reliability of a node-negative SLND in predicting a node negative axilla. METHODS: Eighty-two patients who had clinically negative axillae underwent SLND followed by Level I/II axillary lymph node dissection (ALND). SLNDs were performed using both technetium-99m (Tc-99m) labeled colloid and isosulfan blue dye. SLNs were analyzed by hematoxlyin and eosin and immunocytochemical techniques. RESULTS: SLNs were successfully identified in 80% of patients. Mapping success was decreased among postmenopausal women but was not influenced by preoperative chemotherapy, large tumor size, or previous excisional biopsy. Of the 31 successfully mapped, node positive patients, 5 had false negative (FN) SLNDs (overall FN rate = 16%). Of the 9 successfully mapped patients who had received preoperative chemotherapy and had positive axillary nodes, 3 had FN SLND (FN rate = 33%). The presence of clinically positive lymph nodes before chemotherapy did not predict which patients would have a subsequent FN SLND. T3 tumor size, but not previous excision, was associated significantly with increased FN rate, although the FN rate for previous excision was 11%. No FN SLND occurred with T1/T2 tumors that were not excised previously and had not received preoperative chemotherapy. CONCLUSIONS: Preoperative chemotherapy was associated with an unacceptably high FN rate for SLND. While larger tumor size also was associated with FN SLND, this effect might have been due to preoperative chemotherapy use in these patients. Small sample size precluded determining whether excisional biopsy before mapping increased FN SLND rates independently.

ABSTRACT

The therapeutic options for patients with noninvasive or invasive breast cancer are complex and varied. In many situations, the patient and physician have the responsibility to jointly explore and ultimately select the most appropriate option from among the available alternatives. With rare exception, the evaluation, treatment, and follow-up recommendations contained within these guidelines were based largely on the results of past and present clinical trials. However, there is not a single clinical situation in which the treatment of breast cancer has been optimized with respect to either maximizing cure or minimizing toxicity and disfigurement. Therefore, patient and physician participation in prospective clinical trials allows patients not only to receive state-of-the-art cancer treatment but also to contribute to the improvement of treatment of future patients.

ABSTRACT

PURPOSE: To evaluate sentinel lymph node mapping in patients with breast cancer. MATERIALS AND METHODS: Sixty-two patients with breast cancer scheduled to undergo axillary nodal dissection underwent scintigraphic localization of sentinel lymph nodes with filtered technetium 99m sulfur colloid. At surgery, isosulfan blue was injected. Sentinel nodes were identifiable by blue color and by radioactivity with hand-held gamma probe. Results were analyzed statistically. RESULTS: A sentinel lymph node was identified in 49 patients (79%). Lymph nodes were positive for metastatic disease in 26 patients (42%). The mapping success rate was 78% (n = 21) in the 27 patients with no prior surgery, 78% (n = 18) in the 23 patients with prior surgery, and 86% (n = 12) in the 14 patients with prior chemotherapy. Axillary nodes were positive in 11 (41%) of the 27 patients with no prior intervention, six (26%) of the 23 patients with prior surgery, and 10 (71%) of the 14 patients with prior chemotherapy. There were no false-negative findings in patients without prior intervention. Four patients with positive nodes had false-negative sentinel nodes. CONCLUSION: Sentinel lymph node mapping and biopsy without axillary dissection is appropriate in patients with breast cancer who have not undergone prior intervention. Further study is necessary to ascertain the accuracy of the procedure for patients who have undergone presurgical chemotherapy or previous excisional biopsy.

ABSTRACT

OBJECTIVE: A significant morbidity risk is associated with axillary nodal dissections for breast cancer. Many treatment decisions are based on axillary nodal status. Lymphatic mapping and sentinel node biopsy have been investigated to determine if the histology of the sentinel node reflects the remaining lymph node basin. We describe the technical aspects of sentinel node lymphoscintigraphy for breast cancer. METHODS: Ninety-three patients had lymphoscintigraphy for breast cancer. Patients with palpable lesions had 4 concentric injections around the site and lesions requiring localization had injections made through tubing connected to the localizing wire introducer needle. Immediate static images were acquired and the sentinel node was marked for surgery. Marks were reverified using a handheld gamma probe. RESULTS: Lymph nodes were visualized by lymphoscintigraphy in 87% of cases. Time to visualization of lymph nodes ranged from 1-120 min with a mean of 28 min. An average of 1.5 nodes were visualized. The overall success rate for identifying the sentinel node at time of surgery was 85%. CONCLUSION: We conclude that lymphoscintigraphy for breast cancer is a detailed procedure that requires coordination with radiology and surgery teams to ensure proper identification of sentinel lymph nodes.

ABSTRACT

BACKGROUND: Although the Bcl-2 protein promotes tumor cell survival by blocking programmed cell death (apoptosis), Bcl-2 expression has been associated with favorable prognostic indicators in breast cancer. We hypothesize that despite its antiapoptotic effects, Bcl-2 slows tumor cell proliferation. MATERIALS AND METHODS: Bcl-2-negative breast cancer cells (SKBr3) were transfected with the bcl-2 gene (Bcl2-1 clone, low expression; Bcl2-2 clone, high expression) or plasmid control (Neo). Cell cycle distribution and kinetics were analyzed using bivariate flow cytometry (PI staining and pulse BrdU uptake). Cells were treated for 72 h with doxorubicin (100 ng/ml) or vehicle (0.01% DMSO) and assayed for cytosolic DNA with diphenylamine to measure apoptosis. RESULTS: Cell counting showed increased doubling time in the Bcl-2-expressing clones Bcl2-1 and Bcl2-2 (Bcl-2(+)) relative to the Bcl-2-nonexpressing lines SKBr3 and Neo (Bcl-2(-)). Cell cycle analysis showed a decreased S phase fraction in Bcl-2(+) cells. Pulse BrdU uptake showed an increased G1/G0 fraction in Bcl-2(+) cells. Doxorubicin-induced apoptosis occurred in Bcl-2(-) but not in Bcl-2(+) cell lines. CONCLUSIONS: Despite antiapoptotic effects favoring tumor survival, Bcl-2 prolongs cell cycle. Decreased tumor proliferation may account for the association of Bcl-2 expression with a favorable outcome in breast cancer, even though Bcl-2 may mediate chemoresistance in some patients.
