The association between patients' perceived continuity of care and beliefs about oral anticancer treatment.

PURPOSE: To explore factors associated with necessity beliefs and concerns among patients receiving oral anticancer therapy (OACT) and, specifically, to examine the relationship between continuity of care (COC) and patients' beliefs about OACT. METHODS: A cross-sectional study was conducted among patients from four oncology centers receiving OACT (either targeted, hormonal, or chemotherapy). Two months after OACT initiation, patients were asked to participate in a face-to-face or telephone survey. The Beliefs about Medicines Questionnaire was used to examine patients' perceptions of their personal necessity for OACT and concerns about potential adverse effects. The Nijmegen Continuity Questionnaire was used to assess patients' perceived COC. Data on clinical characteristics were collected from medical records. RESULTS: Participants' beliefs about OACT necessity (n = 91) were found to be associated with COC within the oncology team, and with COC between the oncology specialist and the primary care physicians (ß = 0.27, p = 0.003; ß = 0.22, p = 0.02, respectively), beyond age, depression, and cancer type (ΔR2 = 0.14, p < 0.001). Additionally, the difference between participants' beliefs about OACT necessity and their OACT-related concerns was associated with COC within the oncology team (ß = 0.30, p = 0.001), beyond age, income, family status, and cancer type (ΔR2 = 0.09, p = 0.001). CONCLUSIONS: This study shows that cancer patients' perceptions about the COC between care providers are related to their beliefs about OACT necessity, thus providing evidence for the importance of health care delivery approaches that support COC within the oncology team and between the oncology specialist and the primary care physician.

Long-Term Follow-Up of Chemotherapy-Induced Ovarian Failure in Young Breast Cancer Patients: The Role of Vascular Toxicity.

BACKGROUND: We previously reported that chemotherapy-induced ovarian toxicity may result from acute vascular insult, demonstrated by decreased ovarian blood flow and diminished post-treatment anti-Müllerian hormone (AMH) levels. In the present study, we report the continuous prospective evaluation of ovarian function in that cohort. METHODS: Patients (aged <43 years) with localized breast cancer were evaluated by transvaginal ultrasound prior to initiation of chemotherapy, immediately at treatment completion, and at 6 and 12 months after treatment cessation. Doppler flow velocity indices of the ovarian vasculature (resistance index [RI], pulsatility index [PI]) were visualized. Hormone markers of ovarian reserve were assessed at the same time points. RESULTS: Twenty patients were enrolled in the study. Median age was 34 ± 5.24 years. Ovarian blood flow was significantly reduced immediately following chemotherapy (both RI and PI; p = .01). These parameters were partially recovered at later points of assessment (6 and 12 months after treatment); patients aged <35 years significantly regained ovarian blood flow compared with patients aged >35 years (p < .05). AMH dropped dramatically in all patients following treatment (p < .001) and recovered in only 10 patients. Hormone markers of ovarian reserve shortly after chemotherapy depicted a postmenopausal profile for most patients, accompanied by related symptoms. Follicle-stimulating hormone (FSH) levels recovered in 14 of 20 patients and significantly returned to the premenopausal range in patients aged <35 years (p = .04); 10 of 20 resumed menses at 12 months. The pattern of vascular impairment was lessened in patients treated with a trastuzumab-based protocol, although results did not reach statistical significance (p = .068). CONCLUSION: Continuous prospective evaluation of ovarian vasculature and function in a cohort of young patients during and after chemotherapy indicated that ovarian toxicity may derive from acute vascular insult. Age may affect whether patients regain ovarian function, whereas recovery of blood flow and premenopausal FSH levels at later assessment was notable in patients aged <35 years. IMPLICATIONS FOR PRACTICE: This study explored the role of vascular toxicity in mediating ovarian impairment and recovery following chemotherapy. Continuous prospective evaluation of ovarian vasculature and function in a cohort of young patients during and after chemotherapy indicated that ovarian toxicity may derive from acute vascular insult. Future studies are warranted to further characterize patterns of vascular toxicity of various chemotherapies in clinical practice and to assess the role of chemotherapy-induced vascular toxicity for specific end organs such as the ovary with systemic vascular effect. Elucidating the cause of impairment may facilitate development of measures to minimize vascular toxicity and consequences of acute vascular insult.

Differences in Toxicity Between Ashkenazi and Sephardic Jews With Colon Cancer Treated With Adjuvant Chemotherapy: A Prospective Study.

BACKGROUND/AIM: Ethnicity of cancer patients is increasingly being recognized as an important factor that may influence intergroup variation in toxicity and efficacy of chemotherapy. Data from our institution suggested that differences in chemotherapy-associated toxicity are not limited to distanced ethnic subgroups, such as Caucasians, Afro-Americans, or Asians, but may exist even between two closely related Caucasian ethnic subgroups, such as Ashkenazi and Sephardic Jews. This study aimed to explore differences in severity and frequency of various side effects, including neurotoxicity between patients from the two Jewish subgroups receiving oxaliplatin-containing adjuvant chemotherapy for colon cancer (CC). PATIENTS AND METHODS: We recruited 75 patients, with performance status 0-1 and no background of neuropathy between 2012 and 2016. All patients completed a neurotoxicity questionnaire (NQ) and a QoL questionnaire (QoLQ) at baseline and the NQ also at each treatment cycle; during follow up, patients filled out the NQ and the QoLQ every four months for a total of one year. RESULTS: Of the 75 participants, 66 were evaluable for the study including 34 (52%) Sephardic and 32 (48%) Ashkenazi Jews. Grade ≥2 vomiting and diarrhea occurred more often in Sephardic than in Ashkenazi patients (p=0.008 and 0.012, respectively). Of the 66 evaluable patients, 11 (17%) developed grade 3 neurotoxicity; of these, 9 were Sephardic and 2 were Ashkenazi (p=0.028). There were no significant differences in the dynamics of QoL between both subgroups. CONCLUSION: Sephardic patients receiving oxaliplatin-containing regimens are at an increased risk for neurotoxicity and other side effects as compared to their Ashkenazi counterparts.

Chemotherapy-induced ovarian failure as a prototype for acute vascular toxicity.

BACKGROUND: Chemotherapy-related amenorrhea is a frequent side effect observed in young breast cancer patients. Studies in mice revealed that chemotherapy-induced gonadal toxicity may result from vascular damage. We prospectively evaluated ovarian blood flow and function in young breast cancer patients following chemotherapy. METHODS: Young female patients with localized breast cancer undergoing adjuvant or neoadjuvant anthracycline- or taxane-based chemotherapy were evaluated using transvaginal ultrasound prior to initiation of and immediately after cessation of chemotherapy. Doppler-flow velocity indices of the ovarian vasculature-resistance index (RI), pulsatility index (PI)-and size measurements were visualized. Hormonal profiles, anti-Müllerian hormone (AMH) levels, and menopausal symptoms were assessed at the same time points. RESULTS: Twenty breast cancer patients were enrolled in the study. The median age was 34 ± 5.24 years. Ovarian blood flow was significantly reduced shortly following chemotherapy: RI decreased by 52.5% and PI decreased by 24.2%. The mean ovarian size declined by 19.08%. Patients who were treated with sequential chemotherapy experienced further reductions in ovarian blood flow and ovarian size after the second sequence. AMH levels dropped dramatically in all patients following treatment. Hormonal profiles after treatment depicted a postmenopausal profile for most patients, accompanied by related symptoms. CONCLUSIONS: Our results may imply a mechanism of chemotherapy-induced ovarian toxicity manifested by decreased ovarian blood flow accompanied by a reduction in ovarian size and diminished post-treatment AMH levels. Based upon our former preclinical studies, we assume that this may derive from an acute insult to the ovarian vasculature and may represent an initial event triggering a generalized phenomenon of end-organ toxicity.

Anti-HER2/neu Antibody Reduces Chemotherapy-Induced Ovarian Toxicity-From Bench to Bedside.

BACKGROUND: Trastuzumab, a humanized anti-human epidermal growth factor receptor 2 (HER2/neu) antibody, is considered a standard treatment in addition to chemotherapy in the adjuvant setting for HER2/neu-positive breast cancer, yet its impact on fertility and ovarian reserve remains obscure. We aimed to study the effect of anti-HER2/neu on chemotherapy-induced ovarian toxicity in both clinical and preclinical settings. METHODS: We prospectively enrolled breast cancer patients below the age of 42 years who were treated with chemotherapy with or without trastuzumab into the study. Anti-Müllerian hormone (AMH) was measured 6 and 12 months post-chemotherapy as an ovarian reserve indicator. In the animal model, pubertal mice were injected with cyclophosphamide or paclitaxel with or without anti-HER2/neu, or saline, and sacrificed 1 week or 3 months later. Ovarian apoptosis, proliferation and vascularity were measured by immunohistochemistry and ovarian reserve was measured by morphometric analysis and serum-AMH. RESULTS: Thirty-three patients with early breast cancer were enrolled into the study. Nineteen patients had HER2/neu negative cancer and were treated with chemotherapy and 14 had HER2/neu positive cancer and were treated with chemotherapy and trastuzumab. In all patients, AMH levels declined to undetectable values immediately post-treatment, but regained for 57.1% of the HER2/neu positive cohort and 36.8% of the negative cohort (p < 0.05). In the preclinical setting, anti-HER2/neu antibody, in combination with chemotherapy, displayed lessened ovarian and vascular damage. CONCLUSIONS: Our results indicate that trastuzumab may alleviate chemotherapy-induced ovarian toxicity that may be mediated via its effect on ovarian vasculature.

Prospective Long-Term Follow-Up of Pulmonary Diffusion Capacity Reduction Caused by Dose-Dense Chemotherapy in Patients with Breast Cancer.

BACKGROUND: Our previous study of pulmonary function in 34 patients with early breast cancer without preexisting lung disease showed that anthracycline- and taxane-based adjuvant dose-dense chemotherapy (DDC) caused a significant 16.4% mean reduction in carbon monoxide diffusing capacity (DLCO). The present study reports the pulmonary and oncological outcomes of these patients on long-term follow-up. PATIENTS AND METHODS: The primary endpoint was DLCO measured by the pulmonary function test (PFT) performed at a median of 27 months after DDC (range, 8-97) in 25 patients without disease recurrence. DLCO values were recorded as a percentage of predicted values according to age, height, and hemoglobin level and analyzed relative to baseline pre-DDC DLCO values. The secondary endpoints were symptoms, additional therapies, and cancer outcomes during a median of 11 years' follow-up (range, 4.4-11.4). RESULTS: A longitudinal general linear model showed significant effects of time on DLCO and its trend (F(1, 87) = 14.68, p < 0.001 and F(1, 87) = 10.26, p=0.002, respectively). Complementary descriptive analysis showed a significant recovery on the follow-up PFT (75.6% vs. 81.9%, p=0.002), but it was still significantly lower than the baseline DLCO (81.9% vs. 92.0%, p=0.003). Five patients (20%) still showed a >20% relative DLCO reduction from baseline. Patients with dyspnea or fatigue at later clinical follow-up had a significantly lower DLCO value on the follow-up PFT than nonsymptomatic patients (80.5% vs. 92.1%, p=0.02). DLCO recovery was inversely correlated with age (R = -0.39, p=0.05), but no significant correlation was found with the length of time until the follow-up PFT or additional therapies. There was no association of DDC-related DLCO reduction with cancer outcomes. CONCLUSIONS: The significant reduction in DLCO seen after DDC in patients with potentially curable breast cancer is evident years afterwards, especially in older patients. While most patients partly recover, some will have a lasting symptomatic DLCO impairment.

Factors Affecting Communication Patterns between Oncology Staff and Family Members of Deceased Patients: A Cross-Sectional Study.

OBJECTIVE: Perceptions of the role of oncology medical staff in supporting bereaved families have evolved with the transition to interdisciplinary cancer care. We investigated the interactions between oncology professionals and bereaved families. METHODS: This cross-sectional study involved all oncology medical staff at the Davidoff Center. Participants were given a questionnaire relating to bereavement follow-up. Responses were measured using a 5-point Likert scale. RESULTS: Of 155 staff members, 107 filled questionnaires with <20% missing data and were included in the analysis (α = 0.799; corrected, α = 0.821). Respondents included physicians (35%), nurses (46%), social workers (7%), psychologists (4%), or unspecified (8%); 85% were Jewish, and 60% had ≥10 years of oncology experience. Most respondents thought that contacting bereaved families was important (73%), and that it provided closure for staff (79%); 41% indicated that they contacted >50% of the families of their deceased patients. Contacting bereaved families was considered the responsibility of the physicians (90%), nurses (84%), or social workers (89%). The main barriers to contacting bereaved families were emotional overload (68%) and lack of time (63%); 60% indicated a need for additional communication tools for bereavement follow-up. In a multivariate analysis, profession (physician vs. nurse), primary workplace (outpatient setting vs. other), and self-defined religion were significant variables with respect to the perceived importance of contacting bereaved families and to actually contacting them. Other factors (e.g., age, gender) were non-significant. CONCLUSIONS: Perspectives regarding bereavement actions differ significantly across medical professions, work settings, and self-defined religions. Additional guidance and education regarding bereavement actions is warranted.

ReCAP: Perspectives of Patients, Caregivers, and Medical Staff on Greetings in Oncology Practice: A Prospective Survey.

PURPOSE: Encounters between patients and medical staff are the foundation for building the patient­medical staff relationship, which is a keystone of care. We investigated perspectives of patients, caregivers, and medical staff related to greetings in oncology practice. METHODS: A total of 186 patients (median age, 62 years) and 104 caregivers (median age, 54 years) visiting the outpatient clinics at the Davidoff Cancer Institute completed a questionnaire about greeting-related preferences. Similar questionnaires were completed by 93 staff members (physicians, nurses, secretaries, and psychosocial team). RESULTS: Overall, patients preferred to be addressed informally (ie, by their given name) during first and subsequent meetings with their physician (59% and 75% of patients, respectively). However, most physicians (79%) addressed patients more formally (using surname or full name). Overall, 53% of patients wanted the physician to shake their hand. Physicians reported shaking hands with their patients at the beginning (46%) or end (71%) of the first meeting. Most patients (76%) wanted physicians to formally introduce themselves (by their full name) and mention their academic degree (65%). For other oncology professionals, a majority of patients (63%) preferred an informal introduction (by given name only). No major differences were observed between patients' and caregivers' perspectives. CONCLUSION: This survey provides insights that may help oncology professionals in building relationships with their patients. Specifically, our findings suggest that patients with cancer in Israel prefer a casual environment; yet, they prefer that physicians introduce themselves in a more formal manner.

Adjuvant Docetaxel and Cyclophosphamide (DC) with prophylactic granulocyte colony-stimulating factor (G-CSF) on days 8 &12 in breast cancer patients: a retrospective analysis.

PURPOSE: Four cycles of docetaxel/cyclophosphamide (DC) resulted in superior survival than doxorubicin/cyclophosphamide in the treatment of early breast cancer. The original study reported a 5% incidence of febrile neutropenia (FN) recommending prophylactic antibiotics with no granulocyte colony-stimulating factor (G-CSF) support. The worldwide adoption of this protocol yielded several reports on substantially higher rates of FN events. We explored the use of growth factor (GF) support on days 8 and 12 of the cycle with the original DC protocol. METHODS: Our study included all consecutive patients with stages I-II breast cancer who were treated with the DC protocol at the Institute of Oncology, Davidoff Center (Rabin Medical Center, Petah Tikva, Israel) from April, 2007 to March, 2012. Patient, tumor characteristics, and toxicity were reported. RESULTS: In total, 123 patients received the DC regimen. Median age was 60 years, (range, 25-81 years). Thirty-three patients (26.8%) were aged 65 years and older. Most of the women (87%) adhered to the planned G-CSF protocol (days 8 &12). 96% of the patients completed the 4 planned cycles of chemotherapy. Six patients (5%) had dose reductions, 6 (5%) had treatment delays due to non-medical reasons. Thirteen patients (10.6%) experienced at least one event of FN (3 patients had 2 events), all requiring hospitalization. Eight patients (6.5%) required additional support with G-CSF after the first chemotherapy cycle, 7 because of FN and one due to neutropenia and diarrhea. IN CONCLUSION: Primary prophylactic G-CSF support on days 8 and 12 of the cycle provides a tolerable option to deliver the DC protocol. Our results are in line with other retrospective protocols using longer schedules of GF support.

Student nurses' care of terrorists and their victims.

Nurses are increasingly having to face the dilemma of nursing not only the victims of terrorist attacks but also the terrorist attackers. This study investigated the declared practical intentions of Israeli nursing students regarding their care of both victims and attackers and tried to identify which variables predicted the different intentions.A total of 306 students on a BA nursing program responded to the Priorities in Care Questionnaire, which asked for their responses to five vignettes in which the patient featuring in each vignette was either the victim of a terrorist attack, a terrorist, a criminal or a regular patient. With regard to patients in life-threatening situations, the students displayed no disparity of attitude. By contrast, when the patient was a terrorist and the condition was not life threatening, the students were likely to transfer care to a colleague or postpone their care. The variables found to predict intentions were sex,stage of training, work experience, religion, religiosity and political tendency.
