Stage I Breast Cancer in the Modern Era: A Retrospective Cohort Study of 328 Patients Diagnosed from 2002 to 2006 with a 14- year Median Follow-Up.

INTRODUCTION: This study aimed to evaluate the long-term outcomes of stage I breast cancer (BC) patients diagnosed during the current era of screening mammography, immunohistochemistry receptor testing, and systemic adjuvant therapy. METHODS: A retrospective cohort study was conducted on 328 stage I BC patients treated consecutively in a single referral center with a follow-up period of at least 12 years. The primary endpoints were invasive disease-free survival (IDFS) and overall survival (OS). The influence of tumor size, grade, and subtype on the outcomes was analyzed. RESULTS: Most patients were treated by lumpectomy, sentinel node biopsy and adjuvant endocrine therapy and most (82%) were of subtype luminal-A. Adjuvant chemotherapy was administered to 25.6 % of our cohort. Only 24 patients underwent gene expression testing, which was introduced toward the end of the study period. Mean IDFS was 14.64 years, with a 15-year IDFS of 75.6%. Mean OS was 15.28 years with a 15-year OS of 74.9%. In a Cox multivariate analysis, no clinical or pathologic variable impacted on OS and only tumor size (< 1 centimeter (cm) vs 1-2 cm), impacted significantly on IDFS. During follow-up, 20.1% of the cohort developed second primary cancers, including BC. The median time to diagnosis of a second BC was 6.49 years. CONCLUSION: The study results emphasize the importance of long-term follow-up and screening for subsequent malignancies of patients with stage I BC and support the need for using prognostic and predictive indicators beyond the routine clinicopathological characteristics in luminal-A patients.

Neoadjuvant therapy with doxorubicin-cyclophosphamide followed by weekly paclitaxel in early breast cancer: a retrospective analysis of 200 consecutive patients treated in a single center with a median follow-up of 9.5 years.

PURPOSE: We analyzed outcomes of doxorubicin-cyclophosphamide (AC) followed by weekly paclitaxel as neoadjuvant chemotherapy (NAC) for breast cancer (BC), in an everyday practice with long-term follow-up of patients. METHODS: All patients (n = 200) who received the AC-paclitaxel combination as NAC for BC at the Soroka University Medical Center from 2003 to 2012 were included in this retrospective cohort study. AC was administered on an every 3-week schedule (standard dose) until May, 2007 (n = 99); and subsequently every 2-week dose dense (dd) (n = 101). Clinical pathologic features, treatment course, and outcome information were recorded. Complete pathologic response (pCR) was analyzed according to BC subtype, dose regimen, and stage. RESULTS: Median age was 49 years; 55.5% and 44.5% of patients were clinically stage 2 and 3, respectively. Standard dose patients had more T3 tumors. Subtypes were human epidermal growth factor receptor-2 (HER2)-positive 32.5% (of whom 82% received trastuzumab), hormone receptor-positive/HER2-negative 53%, and triple negative 14.5%. Breast-conserving surgery (BCS) was performed in 48.5% of patients; only 9.5% were deemed suitable for BCS prior to NAC. Toxicity was acceptable. The overall pCR rate was 26.0% and was significantly higher in the dd group and HER2-positive patients. With a median follow-up of 9.51 years median event-free survival (EFS) and overall survival (OS) are 10.85 years and 12.61 years, respectively. Patients achieving pCR had significantly longer EFS and OS. CONCLUSION: NAC for BC with AC-paclitaxel can be safely administered in the "real-world' setting with high efficacy. Current efforts are aimed at increasing rates of pCR and identifying patients who may benefit from additional therapy or conversely, de-escalated treatment.

Direct comparison shows that mRNA-based diagnostics incorporate information which cannot be learned directly from genomic mutations.

BACKGROUND: Compared to the many uses of DNA-level testing in clinical oncology, development of RNA-based diagnostics has been more limited. An exception to this trend is the growing use of mRNA-based methods in early-stage breast cancer. Although DNA and mRNA are used together in breast cancer research, the distinct contribution of mRNA beyond that of DNA in clinical challenges has not yet been directly assessed. We hypothesize that mRNA harbors prognostically useful information independently of genomic variation. To validate this, we use both genomic mutations and gene expression to predict five-year breast cancer recurrence in an integrated test model. This is accomplished first by comparing the feature importance of DNA and mRNA features in a model trained on both, and second, by evaluating the difference in performance of models trained on DNA and mRNA data separately. RESULTS: We find that models trained on DNA and mRNA data give more weight to mRNA features than to DNA features, and models trained only on mRNA outperform models trained on DNA alone. CONCLUSIONS: The evaluation process presented here may serve as a framework for the interpretation of the relative contribution of individual molecular markers. It also suggests that mRNA has a distinct contribution in a diagnostic setting, beyond and independently of DNA mutation data.

Does Assessment Method Matter in Detecting Mental Health Distress among Ashkenazi and Mizrahi Israeli Women with Breast Cancer?

Authors examined differences in assessment method (structured diagnostic interview versus self-report questionnaire) between ethnic groups in the prevalence of mood and anxiety disorders among women with breast cancer. A convenience sample of 88 Mizrahi (Jews of Middle Eastern/North African descent, n = 42) and Ashkenazi (Jews of European/American descent, n = 46) women with breast cancer from oncology units in three health centers across Israel participated in the study. Participants were within eight months of diagnosis. Participants completed the Hospital Anxiety and Depression Scale (HADS) and a structured diagnostic interview, the Mini-International Neuropsychiatric Interview (MINI). Approximately one-third (31.8 percent, n = 28) of participants were diagnosed with at least one mood or anxiety disorder based on the MINI. Significantly more Mizrahi participants (42.9 percent) were diagnosed with at least one mood or anxiety disorder, compared with their Ashkenazi counterparts (21.7 percent). Mean score on HADS was below the optimal cutoff score (≥13) among all participants, with no significant difference in mean score for emotional distress based on HADS between the two ethnic groups. The findings highlight the role of measurement variance in assessing mental health distress among women with breast cancer in general and among ethnic and racial minorities in particular.

The Prognostic Value of the Pretreatment Neutrophil/Lymphocyte Ratio in Patients with Glioblastoma Multiforme Brain Tumors: A Retrospective Cohort Study of Patients Treated with Combined Modality Surgery, Radiation Therapy, and Temozolomide Chemotherapy.

BACKGROUND: Recent studies have shown that the peripheral blood pretreatment neutrophil/lymphocyte ratio (NLR) is a prognostic measure in various cancers. The few studies evaluating NLR in glioblastoma multiforme (GBM) patients yielded inconsistent results. OBJECTIVES: The primary objective of our study was to test the ability of pretreatment NLR to predict the overall survival (OS) and progression-free survival (PFS) of patients with GBM treated by combined modality therapy (surgery, radiation, and temozolomide chemotherapy). A secondary objective was to evaluate the toxicity of the combined modality protocol in a consecutive series of patients treated in our center, in the context of a real-world universal health-care setting. METHODS: We analyzed 89 patients with GBM in a retrospective cohort analysis who were treated in Soroka University Medical Center's Oncology Department between the years 2005-2016. We analyzed NLR as a dichotomous variable at 3 cut-off points, 2.5, 3 and 4, as a predictor of OS and PFS. Methylation status of the O6-methylguanine-DNA methyltransferase (MGMT) promoter was not determined. RESULTS: No significant correlation was found between NLR and either OS or PFS. Factors that predicted a shorter OS were age and extent of surgery. Patients over 70 years of age had a statistically significant shorter OS, 12.5 months (95% CI: 10.4-14.5 months) versus 17.6 months (95% CI: 14.2-21.1 months) in those 70 years of age and younger (p = 0.004). The OS of patients undergoing partial resection (12.7 months 95% CI: 8.3-17.1 months) or biopsy only (9.3 months 95% CI: 7.8-24.6 months), was significantly shorter than that of patients undergoing total resection (18.9 months, 95% CI: 11.8-26.0 months; p = 0.035). There were no treatment-related deaths. The most common grade III-IV toxicities were thrombocytopenia, 12.4%, and fatigue, 13.5%. CONCLUSIONS: In our cohort of GBM patients treated with combined modality therapy, pretreatment NLR was not prognostic. Toxicity of treatment was acceptable. Investigation of the NLR with larger groups of patients selected by MGMT status is warranted.

Impact of a 3-Day Introductory Oncology Course on First-Year International Medical Students.

Although only some medical students will choose cancer as their specialty, it is essential that all students have a basic understanding of cancer and its treatment. The purpose of this study was to evaluate the impact of an introductory clinical oncology course on first-year international medical students. Evaluation of the course involved a quantitative survey designed for this study that was given pre- and post-course completion. Participants included 29 first-year international medical students. Students reported that the course affected them emotionally more than they anticipated it would prior to beginning the course. By the end of the course, students felt more comfortable focusing on how to live with cancer, felt less afraid of dealing with death, and were better able to cope with uncomfortable emotional situations. The course had no significant effect on students' interest in specializing in oncology in the future. Our study provides evidence that an introductory oncology course can increase student comfort with issues related to living with cancer, with confronting and dealing with death and dying, and with coping with uncomfortable emotional situations as related to cancer care. In anticipation of growing shortages in oncology specialists in the coming years, the ability of an early course in oncology to attract more students to the field is of interest. Future research should examine ethnic and cultural differences in uptake of the clinical oncology courses across continents and should use direct observation in addition to self-report in evaluating outcomes.

The 21-gene recurrence score assay (Oncotype DX™) in estrogen receptor-positive male breast cancer: experience in an Israeli cohort.

OBJECTIVE: The 21-gene recurrence score (RS) assay has been widely adopted for use in early estrogen receptor (ER)-positive breast cancer to assess the risk for distant recurrence and the potential benefit of adjuvant chemotherapy. The primary aim of this study was to assess RS distribution in Israeli male breast cancer (MBC) patients. METHODS: The study population included 65 newly diagnosed Israeli MBC patients. Clinical and pathologic data were collected at the time of referral. Pathologic examinations were conducted at the pathology departments of the referring centers. The RS assay (Oncotype DX™) was performed on paraffin-embedded tumor samples at Genomic Health laboratories. RESULTS: The mean age of the patients was 65.1 years (range 38-88 years). Low-risk (RS<18), intermediate-risk (RS 18-30) and high-risk (RS≥31) scores were noted in 29 patients (44.6%), 27 patients (41.5%) and 9 patients (13.9%), respectively. The distribution of RS in male patients was similar to the distribution in 2,455 female patients from Israel referred during the same time period. CONCLUSION: Our data suggest that the distribution of Oncotype DX RS in ER-positive MBC patients is similar to that of female breast cancer patients.

The impact of the 21-gene Recurrence Score assay on clinical decision-making in node-positive (up to 3 positive nodes) estrogen receptor-positive breast cancer patients.

Oncotype DX testing is reimbursed in Israel for node-negative and node-positive (N1+; up to 3 positive nodes including micrometastases), estrogen receptor positive (ER+), breast cancer patients. This retrospective study evaluated the impact of Oncotype DX testing on treatment decisions in N1+/ER+ breast cancer patients. To this end, we compared treatments for all N+ patients for whom testing had been ordered with treatments for patients with similar characteristics where the test had not been available. The retrospective analysis included 951 patients (282 Oncotype DX, 669 controls), all of whom received endocrine therapy with or without chemotherapy. In Oncotype DX patients, 7.1, 37.0, and 100 % of those with low, intermediate, and high Recurrence Score results (Oncotype DX summary score) received chemotherapy, respectively (P < 0.0001, all comparisons). Chemotherapy use was lower in Oncotype DX patients versus controls (24.5 vs. 70.1 %). In a multivariate logistic regression analysis in which the probability of receiving chemotherapy was modeled as a function of Oncotype DX testing, age, tumor size, tumor grade, nodal status, and the interactions between Oncotype DX testing and the other covariates, Oncotype DX testing was associated with significantly lower odds of receiving chemotherapy (odds ratio 0.16; 95 % CI 0.11-0.24; P < 0.0001). In summary, our findings suggest that Oncotype DX testing has a significant impact on reducing chemotherapy use in N1+/ER+ breast cancer patients in Israel.

Bone mineral density in women newly diagnosed with breast cancer: a prospective cohort study.

Estrogen may have opposing effects on health, namely increasing the risk of breast cancer and improving bone health by increasing bone mineral density (BMD). The objective of this study was to compare dual-energy X-ray absorptiometry (DXA) BMD between women newly diagnosed with breast cancer and matched controls without breast cancer. Women newly diagnosed with breast cancer treated between April 2012 and October 2017 were prospectively enrolled. A control group was established of women with negative mammography or breast ultrasound, matched 1:1 by age, body mass index, parity, and the use of hormone replacement therapy. All those included had DXA BMD, and lab assessments at enrollment. Of 869 women with newly diagnosed breast cancer, 464 signed informed consent. Of the 344 who completed the study protocol, 284 were matched to controls. Overall, the mean age was 58 years. Compared to the control group, for the breast cancer group, the mean vitamin D level was lower (48.9 ± 19.0 vs. 53.8 ± 28.8 nmol/L, p = 0.022); and mean values were higher of total hip BMD (0.95 ± 0.14 vs. 0.92 ± 0.12 g/cm2, p = 0.002), T score (-0.38 ± 1.17 vs. -0.68 ± 0.98, p = 0.002), and Z score (0.32 ± 1.09 vs. 0.01 ± 0.88, p < 0.001). Among the women with breast cancer, no correlations were found of baseline BMD with tumor size or grade, nodal involvement, or breast cancer stage. We concluded that women with newly diagnosed breast cancer tend to have higher BMD than women with similar characteristics but without breast cancer. This implies that BMD might be considered a biomarker for breast cancer risk.

The protective effect of zoledronic acid on bone loss in postmenopausal women with early breast cancer treated with sequential tamoxifen and letrozole: a prospective, randomized, phase II trial.

OBJECTIVE: This study reports the efficacy and safety of zoledronic acid (ZOL) in preventing bone loss in postmenopausal patients receiving an aromatase inhibitor (AI) following tamoxifen. METHODS: Postmenopausal patients with stage I-III hormone receptor-positive breast cancer who received tamoxifen for 2.5-3 years were randomized to receive letrozole (2.5 mg/day) with (n = 47) or without (n = 43) ZOL (4 mg i.v. every 6 months) for 2 years. The primary endpoint was percent change from baseline in lumbar spine (LS) bone mineral density (BMD) up to 60 months. RESULTS: Ninety patients (86 evaluable) with a median age of 59 years (42.9-83.6), 50/86 of whom had previously been treated with chemotherapy, were followed for a median time of 41.4 months. While the control group showed a significant decrease in LS T-score (p = 0.0005), the ZOL group presented an increase over time (p = 0.0143). Change over time in LS T-score was significantly different between groups, favoring ZOL (p < 0.0001 at 24 and 48 months). No fractures, renal dysfunction or osteonecrosis of the jaw were reported. The toxicity profile was similar to those previously reported for each drug. CONCLUSION: The addition of ZOL to letrozole was safe and efficacious in maintaining LS BMD in postmenopausal patients with hormone receptor-positive breast cancer and who were receiving letrozole following 2.5-3 years of tamoxifen.

Analysis of memory deficits following chemotherapy in breast cancer survivors: evidence from the doors and people test.

Studies of cognitive effects of chemotherapy among breast cancer patients show that not all women who are exposed to chemotherapy develop cognitive dysfunction and that the observed declines in cognitive functioning may be quite subtle. The use of measures that are sensitive to subtle cognitive decline are recommended yet rarely used among clinical populations. The purpose of this study is to specify the types of memory changes observed among breast cancer survivors treated with chemotherapy and tamoxifen, by using an analytic test of memory, the Doors and People test, which uses age-adjusted norms. The participants were 40 women who were survivors of breast cancer, 20 of whom had completed chemotherapy treatment and 20 women who were treated only with tamoxifen. There were no significant differences between the two groups in overall scores and in all four subtests: visual memory, verbal memory, recall, and recognition measured by age-adjusted scores. Forty percent of patients in both of the groups were classified as having mild impairment in episodic memory. No between-group differences were found in the frequency of subjective, cognitive complaints. Subjective complaints were reported by 69% of patients but were unrelated to objective performance. Memory deficits were observed in breast cancer patients who receive either chemotherapy or tamoxifen alone compared to age-adjusted norms. The Doors and People Test is a sensitive measure of memory deficits that is feasible for use with clinical populations of breast cancer patients in order to monitor changes in cognitive function.

Ten-year clinical outcomes in N0 ER+ breast cancer patients with Recurrence Score-guided therapy.

The 21-gene Recurrence Score (RS) assay is a validated prognosticator/predictor of chemotherapy (CT) benefit in early-stage estrogen receptor (ER)-positive breast cancer (BC). Long-term data from real-life clinical practice where treatment was guided by the RS result are lacking. We performed exploratory analysis of the Clalit Health Services (CHS) registry, which included all CHS patients with node-negative ER+ HER2-negative BC who underwent RS testing between 1/2006 and 12/2009 to determine 10-year Kaplan-Meier estimates for distant recurrence/BC-specific mortality (BCSM) in this cohort. The analysis included 1365 patients. Distribution of RS results: RS 0-10, 17.8%; RS 11-25, 62.5%; RS 26-100, 19.7%. Corresponding CT use: 0, 9.4, and 69.9%. Ten-year distant recurrence rates in patients with RS 0-10, 11-25, and 26-100: 2.6% (95% confidence interval [CI], 1.1-6.2%), 6.1% (95% CI, 4.4-8.6%), and 13.1% (95% CI, 9.4-18.3%), respectively (P < 0.001); corresponding BCSM rates: 0.7% (95% CI 0.1-5.1%), 2.2% (95% CI, 1.3-3.7%), and 9.5% (95% CI, 6.0-14.9%) (P < 0.001). When the analysis included patients treated with endocrine therapy alone (95.5/87.5% of patients with RS 0-10/11-25), 10-year distant recurrence and BCSM rates for RS 0-10 patients were 2.7% (95% CI, 1.1-6.5%) and 0.8% (95% CI, 0.1-5.3%), respectively, and for RS 11-25 patients, 5.7% (95% CI, 3.9-8.3%) and 2.0% (95% CI, 1.1-3.7%), respectively. For RS 11-25 patients, no statistically significant differences were observed in 10-year distant recurrence/BCSM rates between CT-treated and untreated patients; however, this should be interpreted cautiously since the number of events was low and patients were not randomized. In conclusion, in node-negative ER+ HER2-negative BC patients, where treatment decisions in real-life clinical practice incorporated the RS, patients with RS 0-25 (~80% of patients, <10% CT use) had excellent outcomes at 10 years. Patients with RS 26-100 had high distant recurrence risk despite CT use and are candidates for new treatment approaches.

[Cancer-related lymphedema in Israel].

Lymphedema, the accumulation of protein-rich fluid in an involved extremity or other body part, is a chronic life-long condition following many types of surgical procedures, most often breast cancer surgical therapy. The patient suffering from lymphedema faces difficult medical, social, psychological and aesthetic issues. The incidence of lymphedema after modern breast cancer surgical treatment has been reported for between 5 to 56% of patients. Taking into account the incidence of breast cancer in Israel, there could be a yearly incidence of over 1000 new patients per year in Israel suffering from arm lymphedema. The authors reviewed the literature concerning epidemiology, pathophysiology, risk factors, diagnosis and treatment strategy. In addition, some insights were provided regarding lymphedema treatment in Israel. This review aims to improve the awareness and knowledge of physicians and other health care professionals on this treatable but often forgotten condition.

Clinical outcomes in ER+ HER2 -node-positive breast cancer patients who were treated according to the Recurrence Score results: evidence from a large prospectively designed registry.

The Recurrence Score® is increasingly used in node-positive ER+ HER2-negative breast cancer. This retrospective analysis of a prospectively designed registry evaluated treatments/outcomes in node-positive breast cancer patients who were Recurrence Score-tested through Clalit Health Services from 1/2006 through 12/2011 (N = 709). Medical records were reviewed to verify treatments/recurrences/survival. Median follow-up, 5.9 years; median age, 62 years; 53.9% grade 2; 69.8% tumors ≤ 2 cm; 84.5% invasive ductal carcinoma; 42.0% N1mi, and 37.2%/15.5%/5.2% with 1/2/3 positive nodes; 53.4% Recurrence Score < 18, 36.4% Recurrence Score 18-30, and 10.2% Recurrence Score ≥ 31. Overall, 26.9% received adjuvant chemotherapy: 7.1%, 39.5%, and 86.1% in the Recurrence Score < 18, 18-30, and ≥ 31 group, respectively. The 5-year Kaplan-Meier estimates for distant recurrence were 3.2%, 6.3%, and 16.9% for these respective groups and the corresponding 5-year breast cancer death estimates were 0.5%, 3.4%, and 5.7%. In Recurrence Score < 18 patients, 5-year distant-recurrence rates for N1mi/1 positive node/2-3 positive nodes were 1.2%/4.4%/5.4%. As patients were not randomized to treatment and treatment decision is heavily influenced by Recurrence Score, analysis of 5-year distant recurrence by chemotherapy use was exploratory and should be interpreted cautiously: In Recurrence Score < 18, recurrence rate was 7.7% in chemotherapy-treated (n = 27) and 2.9% in chemotherapy-untreated patients (n = 352); P = 0.245. In Recurrence Score 18-30, recurrence rate in chemotherapy-treated patients (n = 102) was significantly lower than in untreated patients (n = 156) (1.0% vs. 9.7% P = 0.019); in Recurrence Score ≤ 25 (the RxPONDER study cutoff), recurrence rate was 2.3% in chemotherapy-treated (n = 89) and 4.4% in chemotherapy-untreated patients (n = 488); P = 0.521. In conclusion, our findings support using endocrine therapy alone in ER+ HER2-negative breast cancer patients with micrometastases/1-3 positive nodes and Recurrence Score < 18.

Clinical outcomes in patients with node-negative breast cancer treated based on the recurrence score results: evidence from a large prospectively designed registry.

The 21-gene Recurrence Score® (RS) assay is a validated prognostic/predictive tool in ER + early-stage breast cancer. However, clinical outcome data from prospective studies in RS ≥ 11 patients are lacking, as are relevant real-life clinical practice data. In this retrospective analysis of a prospectively designed registry, we evaluated treatments/clinical outcomes in patients undergoing RS-testing through Clalit Health Services. The analysis included N0 ER + HER2-negative breast cancer patients who were RS-tested from 1/2006 through 12/2010. Medical records were reviewed to verify treatments/recurrences/survival. The cohort included 1801 patients (median follow-up, 6.2 years). Median age was 60 years, 50.4% were grade 2 and 81.1% had invasive ductal carcinoma; 48.9% had RS < 18, 40.7% RS 18-30, and 10.4% RS ≥ 31, with chemotherapy use of 1.4, 23.7, and 87.2%, respectively. The 5-year Kaplan-Meier estimates for distant recurrence were 0.8, 3.0, and 8.6%, for patients with RS < 18, RS 18-30 and RS ≥ 31, respectively; the corresponding 5-year Kaplan-Meier estimates for breast cancer death were 0.0, 0.9, and 6.2%. Chemotherapy-untreated patients with RS < 11 (n = 304) and 11-25 (n = 1037) (TAILORx categorization) had 5-year Kaplan-Meier estimates for distant recurrence risk/breast cancer death of 1.0%/0.0% and 1.3%/0.4%, respectively. Our results extend those of the prospective TAILORx trial: the 5-year Kaplan-Meier estimates for distant recurrence and breast cancer death rate for the RS < 18 patients were very low supporting the use of endocrine therapy alone. Furthermore, in chemotherapy-untreated patients with RS 11-25 (where TAILORx patients were randomized to chemoendocrine or endocrine therapy alone), 5-year distant recurrence rates were also very low, suggesting that chemotherapy would not have conferred clinically meaningful benefit.

Disseminated intravascular coagulation at presentation of advanced gastric cancer.

BACKGROUND: Disseminated intravascular coagulation associated with malignant bone marrow involvement has been described as a rare complication of gastric carcinoma and most patients die within 1-4 weeks. Effective chemotherapy of the underlying malignancy may be the only way to control acute DIC. OBJECTIVES: To assess the benefit of infusional 5-fluorouracil as the primary treatment of metastatic gastric carcinoma and DIC at diagnosis. METHODS: From February 2001 to January 2005, six women (median age 48 years) with gastric carcinoma who presented with diffuse bone metastases and acute DIC were treated in our department. Diagnosis was based on primary gastric and bone marrow biopsies. DIC was confirmed by laboratory findings. Initial treatment consisted of infusional 5FU 200 mg/m2/day. When the bleeding tendency stopped, cisplatin 60 mg/m2 and epirubicin 50 mg/m2 every 3 weeks were added. RESULTS: Within one week of starting the treatment, the clinical and laboratory signs of acute DIC were resolved in five of six patients. Upon clinical improvement, five patients subsequently received epirubicin and cisplatin. Survival, however, was short (mean 15 weeks). All patients died with symptoms of bleeding, showing clinical and laboratory signs of DIC. CONCLUSIONS: Based on our experience, infusional 5FU is an effective regimen with negligible myelosuppression; thus, it may be a good choice as initial therapy for this group of patients. The response induced by protracted 5FU was usually short and lasted for only a few weeks. Therefore, once DIC symptoms are controlled, the addition of newer cytotoxic drugs may be necessary to consolidate the remission.

Metastatic tumors to the jaws: a report of eight new cases.

PURPOSE: The purpose of the article is to present 8 new cases of metastatic tumors occurring in the jawbones, their clinical features , diagnostic workup and management. PATIENTS AND METHODS: The records of 8 patients with metastatic jaw lesions were reviewed. Demographic data, presenting symptoms, primary tumor site, radiographic findings, bone scintigraphy , histopathology and clinical management were analyzed. RESULTS: The patients , ranged in age from 44 to 80 years, with a mean of 64.5 years. The primary malignant sites were: the lung , the breast , the rectum, the thyroid, the uterus and the parotid gland . The mandible was the site of oral involvement in seven cases and the maxilla in one. There was no gender difference with respect to the oral site affected. The clinical jaw presentations were: exophytic soft tissue mass, paresthesia of the lower lip and a periapical lesion The provided treatment protocols were: chemotherapy , radiotherapy and chemotherapy, surgery and chemotherapy and supportive care only. In one case the jaw lesion was the first indication of an unknown malignancy at a distant primary site. CONCLUSIONS: Metastatic jaw lesions are uncommon. Paresthesia of the lower lip and the chin is a sinister sign for patients with a metastatic jaw lesion. In view of these cases it can be said that meticulous work-up of of jaw lesions suspected of being metastatic, may be life saving or extend the patient s survival period.

The preoperative neutrophil/lymphocyte ratio does not correlate with the 21-gene recurrence score in estrogen receptor-positive breast cancer patients.

AIMS: The aim of this study was to examine the correlation, if any, between the preoperative neutrophil/lymphocyte ratio (NLR) and the OncotypeDX™ 21-gene recurrence score (RS) in patients with early-stage estrogen receptor (ER)-positive breast cancer (BC). MATERIALS AND METHODS: We retrospectively reviewed the medical records of patients diagnosed with primary ER-positive BC who were referred for the RS assay. The correlation between the preoperative NLR and the RS was analyzed. RESULTS: For the 242 patients with sufficient data for analysis, the median age at diagnosis was 59.5 years. The tumor size ranged from 0.50 to 5.50 cm, with a mean size of 1.8 cm; 73.2% of the tumors were < 2 cm in size. Most of the tumors (66.3%) were of grade 2; the rest was nearly equally divided between grades 1 and 3. The test results for the progesterone receptor (PR) were positive in 86.6% of the cases. Lymph node metastases were present in 22.3% of the patients. The median RS was 18 (range 0-60) and the mean NLR value was 2.11 (range 0.49-7.49). We found no significant correlation between the NLR and the RS. CONCLUSION: Our data suggest that the preoperative NLR does not predict the 21-gene RS in patients with early-stage hormone-sensitive BC.

Early exposure to a clinical oncology course during the preclinical second year of medical school.

PROBLEM: Although only some medical students pursue a career in oncology, all should have a basic understanding of the issues surrounding cancer and its treatment. The authors designed and implemented a one-week introductory clinical oncology course for second-year medical students at Ben Gurion University of the Negev. The course presents a holistic approach to caring for patients with cancer that goes beyond the biological aspects of the disease. APPROACH: In 2013, the authors interviewed four former students and surveyed all current students before and after they completed the course to evaluate its reception and effectiveness. OUTCOMES: Of the 86 students in the course, 77 (90%) completed both the pre- and postcourse surveys. After taking the course, more students reported being concerned about ethical issues, being emotionally stirred by the course, being comfortable speaking with a cancer patient about death and dying, and being comfortable with the fact that the course dealt with issues of death and loss and with "how to live with cancer." In addition, more students reported a fear of causing a cancer patient suffering because of a treatment yet viewed cancer optimistically. Finally, more students considered specializing in oncology. NEXT STEPS: That students reported increased empathy toward cancer patients despite increased trepidation about causing them suffering is promising. Such courses may be one way to counteract the decrease in empathy among students as they progress through medical school. As such, medical schools might consider including this type of curriculum in their preclinical oncology studies.

Breast cancer survivors are at an increased risk for osteoporotic fractures not explained by lower BMD: a retrospective analysis.

BACKGROUND: An association between higher bone mineral density (BMD) and the diagnosis of breast cancer (BC) has been reported. Data on the risk of osteoporotic fractures in women with BC are conflicting. AIMS: The objective of this study was to assess fracture risk adjusted for BMD in women with and without BC, and to assess whether fracture risk in BC patients is attributed to BMD or BC characteristics. METHODS: Using electronic medical records of patients who underwent dual energy X-ray absorptiometry BMD studies at Soroka University Medical Center between February 2003 and March 2011, we identified women with subsequent diagnosis of osteoporotic fractures. BC status, demographic, health characteristics, BMD, and other laboratory findings were assessed. In BC patients data on grade, stage, and treatment were collected. Primary outcome was osteoporotic fracture, analyzed by Cox proportional hazards regression models. RESULTS: During a median follow-up of 4.9 years in 17,110 women with BMD testing (658 BC patients), 1,193 women experienced an osteoporotic fracture (62 in BC and 1,131 in no-BC groups). In multivariate analysis adjusted for age, body mass index (BMI) and BMD, hazard ratio (HR) for any osteoporotic fracture in women with BC was 1.34 (P=0.026). BMD was similar among women with and without BC who fractured. BC patients who experienced an osteoporotic fracture had a trend for less-advanced BC, lower rates of chemotherapy treatment, and higher rates of tamoxifen treatment. CONCLUSIONS: BC survivors are at increased risk of an osteoporotic fracture, which is not explained by worse BMD. Chemotherapy or aromatase inhibitors did not contribute substantially to fracture risk among our BC survivors.
