RESUMO

Anthracycline-based chemotherapy is widely used in the management of breast cancer. Despite the lack of clinical evidence, obtaining prechemotherapy left ventricular ejection fraction (LVEF) by echocardiogram or multigated acquisition scan is a widely adopted practice throughout the world. We present here the results of a retrospective analysis of breast cancer patients who had LVEF measurements in anticipation of an anthracycline chemotherapy to determine whether predefined cardiac risk factors predicted for poor cardiac function. Retrospective data were analyzed from 482 female breast cancer patients in whom LVEF was measured before starting anthracycline-based chemotherapy. Baseline demographics and multiple risk factors associated with congestive heart failure were collected. Twenty-six possible risk factors for CHF were defined, and the frequency of finding an abnormal LVEF as a function of total risk factors was assessed. Statistical tests include chi-squared and logistic regression analysis. The median age of the study population was 52 years. The original chemotherapy plan was changed in 7 patients (1.45%) based on LVEF findings, all of which had asymptomatic LV dysfunction (LVEF ranging 40%-50%). In 32 patients, despite normal LVEF results, anthracyclines were omitted secondary to prior cardiac issues. In 17 patients where LVEF was reported normal, anthracyclines were skipped based on patient's preference, tumor characteristics, or upstaging of the cancer based on imaging studies. No patient with ≤2 risk factors had an abnormal LVEF (N = 350). The probability of finding an abnormal LVEF in patients without any cardiac risk factors is extremely rare. Skipping baseline LVEF assessment may be an option in some patients with no cardiac risk factors undergoing anthracycline-based chemotherapy.

RESUMO

BACKGROUND: Among patients with breast cancer, obesity has been associated with an increased likelihood of having triple-negative breast cancer (TNBC). This association has been thought to be due to the antiapoptotic effects of obesity-related proteins. However, the effect of obesity on the outcomes in patients with TNBC remains unclear. We hypothesized that obesity would be associated with decreased overall survival and disease-free survival in these patients. MATERIALS AND METHODS: A retrospective review of a prospectively maintained database was conducted of patients treated for breast cancer at an academic medical center from March 1998 to September 2011. The body mass index (BMI) of patients with TNBC was calculated at diagnosis. The patients were categorized as normal (BMI < 25 kg/m(2)), overweight (BMI 25-30 kg/m(2)), or obese (BMI > 30 kg/m(2)). The endpoints of overall survival and disease-free survival were analyzed. RESULTS: A total of 183 patients with TNBC were included for analysis. Of the 183 patients, 24 (13.1%) were normal (BMI < 25 kg/m(2)), 42 (23.1%) were overweight (BMI 25-30 kg/m(2)), and 117 (63.7%) were obese (BMI > 30 kg/m(2)). The median follow-up period was 42.5 months. Of the 183 patients, 2 (9.1%) died in the normal group, 10 (23.1%) died in the overweight group, and 25 (21.4%) died in the obese group (P = 0.28). The patients who were overweight or obese had larger tumors (P = 0.02), a higher T stage (P = 0.001), and higher tumor grade (P = 0.01) than the normal BMI patients. By Kaplan-Meier analysis, normal patients had higher overall survival than the overweight or obese patients, but this difference was not statistically significant (P = 0.29). Disease-free survival was also not significantly different (P = 0.91). CONCLUSIONS: Despite an increased frequency of larger tumors, higher T stage, and higher tumor grade, obesity was not associated with decreased overall or disease-free survival in patients with TNBC.

RESUMO

Superwarfarin vitamin K antagonists are found in rat poisons and are readily available. Pediatric exposures are common but are usually asymptomatic without significant coagulopathy. Superwarfarin intoxication must be considered in any adult who presents with an unexplained coagulopathy with extreme elevation of prothrombin time and partial thromboplastin time with associated depletion of vitamin K dependent factors. If superwarfarin toxicity is confirmed, intentional ingestion should be considered, as a large quantity of ingested rat poison is necessary to induce a coagulopathy. Patients with superwarfin induced coagulopathy require several months of high dose oral and parenteral vitamin K supplementation. We describe two patients with superwarfarin toxicity treated at Louisiana State University Health in Shreveport and review pathophysiology and patient management.

RESUMO

BACKGROUND: Tamoxifen is standard adjuvant treatment for postmenopausal women with hormone-receptor-positive breast cancer. We assessed the benefit of adding chemotherapy to adjuvant tamoxifen and whether tamoxifen should be given concurrently or after chemotherapy. METHODS: We undertook a phase 3, parallel, randomised trial (SWOG-8814, INT-0100) in postmenopausal women with hormone-receptor-positive, node-positive breast cancer to test two major objectives: whether the primary outcome, disease-free survival, was longer with cyclophosphamide, doxorubicin, and fluorouracil (CAF) given every 4 weeks for six cycles plus 5 years of daily tamoxifen than with tamoxifen alone; and whether disease-free survival was longer with CAF followed by tamoxifen (CAF-T) than with CAF plus concurrent tamoxifen (CAFT). Overall survival and toxicity were predefined, important secondary outcomes for each objective. Patients in this open-label trial were randomly assigned by a computer algorithm in a 2:3:3 ratio (tamoxifen:CAF-T:CAFT) and analysis was by intention to treat of eligible patients. Groups were compared by stratified log-rank tests, followed by Cox regression analyses adjusted for significant prognostic factors. This trial is registered with ClinicalTrials.gov, number NCT00929591. FINDINGS: Of 1558 randomised women, 1477 (95%) were eligible for inclusion in the analysis. After a maximum of 13 years of follow-up (median 8.94 years), 637 women had a disease-free survival event (tamoxifen, 179 events in 361 patients; CAF-T, 216 events in 566 patients; CAFT, 242 events in 550 patients). For the first objective, therapy with the CAF plus tamoxifen groups combined (CAFT or CAF-T) was superior to tamoxifen alone for the primary endpoint of disease-free survival (adjusted Cox regression hazard ratio [HR] 0.76, 95% CI 0.64-0.91; p=0.002) but only marginally for the secondary endpoint of overall survival (HR 0.83, 0.68-1.01; p=0.057). For the second objective, the adjusted HRs favoured CAF-T over CAFT but did not reach significance for disease-free survival (HR 0.84, 0.70-1.01; p=0.061) or overall survival (HR 0.90, 0.73-1.10; p=0.30). Neutropenia, stomatitis, thromboembolism, congestive heart failure, and leukaemia were more frequent in the combined CAF plus tamoxifen groups than in the tamoxifen-alone group. INTERPRETATION: Chemotherapy with CAF plus tamoxifen given sequentially is more effective adjuvant therapy for postmenopausal patients with endocrine-responsive, node-positive breast cancer than is tamoxifen alone. However, it might be possible to identify some subgroups that do not benefit from anthracycline-based chemotherapy despite positive nodes. FUNDING: National Cancer Institute (US National Institutes of Health).

RESUMO

Inflammatory breast cancer (IBC) is a rare and most aggressive form of breast cancer. The onset and progression of disease are rapid; diagnosis must be made expediently to initiate treatment quickly. In this review, the clinical presentation, trimodal therapy, surgical principles and a brief summary of the Louisiana State University at Shreveport experience with IBC are presented. With this aggressive approach, 5-year survival of better than 40-50% can be expected. This represents a substantive improvement in clinical outcome for IBC patients compared with 30 years ago.

RESUMO

BACKGROUND: Papulopustular rash is a common class effect of epidermal growth factor receptor inhibitors (EGFRI) that can affect patients' health-related quality of life and cause disruptions to treatment. SWOG S1013 (NCT01416688) is a multi-center study designed to validate the Functional Assessment of Cancer Therapy EGFRI 18 (FACT-EGFRI 18) using 7-items from the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 to assess EGFRI-induced skin-related toxicities and their impact on functional status. METHODS: Patients with a diagnosis of colorectal or lung cancer to receive EGFRI therapies for at least 6 weeks were enrolled. Patient self-assessments using the FACT-EGFRI 18 were completed prior to undergoing CTCAE assessment by trained clinicians at baseline, weekly × 6, and then monthly × 3. The psychometric properties of the FACT-EGFRI 14 (skin toxicity items only) and 18 (plus 2 nail and 2 hair items) were established based on criterion validity, known groups validity, internal consistency reliability, and responsiveness to change. RESULTS: Of the 146 registered patients, 124 were evaluable. High Cronbach's alpha (> 0.70) for both FACT-EGFRI 14 and FACT-EGFRI 18 scores across assessment times were observed. Although agreement (i.e. criterion validity) between individual and summary scales of the FACT-EGFRI 18 for assessing skin toxicity was good, agreement with the clinician-reported CTCAE was only fair. The minimal important difference was determined to be 3 points. The results also demonstrated responsiveness to symptom change. DISCUSSION: Based on the results of this multi-center validation study, the FACT-EGFRI 18 patient-reported outcome instrument provided data from the patient's perspective yielding unique information as well as complementing clinician-rated CTCAE grades, especially for the symptoms of pain, pruritus, and paronychia. CONCLUSIONS: Good to excellent psychometric properties for the FACT-EGFRI 18 were demonstrated, supporting further use of this patient-reported outcomes measure. Additional validation with a more diverse group of patients should be conducted.

RESUMO

IMPORTANCE: Universal screening of patients with newly diagnosed cancer for hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV is not routine in oncology practice, and experts disagree about whether universal screening should be performed. OBJECTIVE: To estimate the prevalence of HBV, HCV, and HIV infection among persons with newly diagnosed cancer. DESIGN, SETTING, AND PARTICIPANTS: Multicenter prospective cohort study of patients with newly diagnosed cancer (ie, identified within 120 days of cancer diagnosis) at 9 academic and 9 community oncology institutions affiliated with SWOG (formerly the Southwest Oncology Group) Cancer Research Network, a member of the National Clinical Trials Network, with enrollment from August 29, 2013, through February 15, 2017. The data analysis was conducted using data available through August 17, 2017. MAIN OUTCOMES AND MEASURES: The accrual goal was 3000 patients and the primary end point was the presence of HBV infection (previous or chronic), HCV infection, or HIV infection at enrollment. Patients with previous knowledge of infection as well as patients with unknown viral viral status were evaluated. RESULTS: Of 3092 registered patients, 3051 were eligible and evaluable. Median (range) age was 60.6 (18.2-93.7) years, 1842 (60.4%) were female, 553 (18.1%) were black, and 558 (18.3%) were Hispanic ethnicity. Screened patients had similar clinical and demographic characteristics compared with those registered. The observed infection rate for previous HBV infection was 6.5% (95% CI, 5.6%-7.4%; n = 197 of 3050 patients); chronic HBV, 0.6% (95% CI, 0.4%-1.0%; n = 19 of 3050 patients); HCV, 2.4% (95% CI, 1.9%-3.0%; n = 71 of 2990 patients); and HIV, 1.1% (95% CI, 0.8%-1.6%; n = 34 of 3045). Among those with viral infections, 8 patients with chronic HBV (42.1%; 95% CI, 20.3%-66.5%), 22 patients with HCV (31.0%; 95% CI, 20.5%-43.1%), and 2 patients with HIV (5.9%; 95% CI, 0.7%-19.7%) were newly diagnosed through the study. Among patients with infections, 4 patients with chronic HBV (21.1%; 95% CI, 6.1%-45.6%), 23 patients with HCV (32.4%; 95% CI, 21.8%-44.5%), and 7 patients with HIV (20.6%; 95% CI, 8.7%-37.9%) had no identifiable risk factors. CONCLUSIONS AND RELEVANCE: Results of this study found that a substantial proportion of patients with newly diagnosed cancer and concurrent HBV or HCV are unaware of their viral infection at the time of cancer diagnosis, and many had no identifiable risk factors for infection. Screening patients with cancer to identify HBV and HCV infection before starting treatment may be warranted to prevent viral reactivation and adverse clinical outcomes. The low rate of undiagnosed HIV infection may not support universal screening of newly diagnosed cancer patients.

RESUMO

Purpose Adherence to aromatase inhibitor (AI) therapy for early-stage breast cancer is limited by AI-associated musculoskeletal symptoms (AIMSS). Duloxetine is US Food and Drug Administration approved for treatment of multiple chronic pain disorders. We hypothesized that treatment of AIMSS with duloxetine would improve average joint pain compared with placebo. Methods This randomized, double-blind, phase III trial included AI-treated postmenopausal women with early-stage breast cancer and who had average joint pain score of ≥ 4 out of 10 that developed or worsened since AI therapy initiation. Patients were randomly assigned 1:1 to duloxetine or placebo for 13 weeks. The primary end point was average joint pain through 12 weeks, examined using multivariable linear mixed models, adjusted for stratification factors (baseline pain score of 4 to 6 v 7 to 10 and prior taxane use). Clinically significant change in average pain was defined as a ≥ 2-point decrease from baseline. Results Of 299 enrolled patients, 127 patients treated with duloxetine and 128 who received placebo were evaluable for the primary analysis. By 12 weeks, the average joint pain score was 0.82 points lower for patients who received duloxetine compared with those who received placebo (95% CI, -1.24 to -0.40; P = .0002). Similar patterns were observed for worst joint pain, joint stiffness, pain interference, and functioning. Rates of adverse events of any grade were higher in the duloxetine-treated group (78% v 50%); rates of grade 3 adverse events were similar. Conclusion Results of treatment with duloxetine for AIMSS were superior to those of placebo among women with early-stage breast cancer, although it resulted in more frequent low-grade toxicities.

RESUMO

Two patients with breast cancer received docetaxel-containing chemotherapy as adjuvant or neoadjuvant therapy during pregnancy. The first pregnant patient began neoadjuvant therapy with doxorubicin/cyclophosphamide at 14 weeks of gestation. After 4 cycles of doxorubicin/cyclophosphamide and surgery, she received adjuvant docetaxel for 4 cycles. The second patient began neoadjuvant therapy with doxorubicin/docetaxel at 14 weeks of gestation and received 6 cycles. The fetus of the first patient had hydrocephalus on ultrasound at 17 weeks of gestation (before docetaxel therapy) that persisted on serial follow-up ultrasounds and spontaneously regressed over several months after delivery. No fetal malformations were detected in the second fetus. These 2 cases add to the existing data on the use of taxanes during pregnancy. Although the data are limited with case reports, pregnant patients with cancer can be treated with chemotherapy including taxanes during the second and third trimesters without significant risks to the fetus. Taxanes should not be excluded, if indicated, in pregnant patients with cancer.

RESUMO

PURPOSE: To determine the optimal dose and schedule of anthracycline and taxane administration as adjuvant therapy for early-stage breast cancer. PATIENTS AND METHODS: A 2 × 2 factorial design was used to test two hypotheses: (1) that a novel continuous schedule of doxorubicin-cyclophosphamide was superior to six cycles of doxorubicin-cyclophosphamide once every 2 weeks and (2) that paclitaxel once per week was superior to six cycles of paclitaxel once every 2 weeks in patients with node-positive or high-risk node-negative early-stage breast cancer. With 3,250 patients, a disease-free survival (DFS) hazard ratio of 0.82 for each randomization could be detected with 90% power with two-sided α = .05. Overall survival (OS) was a secondary outcome. RESULTS: Interim analyses crossed the futility boundaries for demonstrating superiority of both once-per-week regimens and once-every-2-weeks regimens. After a median follow-up of 6 years, a significant interaction developed between the two randomization factors (DFS P = .024; OS P = .010) in the 2,716 patients randomly assigned in the original design, which precluded interpretation of the two factors separately. Comparing all four arms showed a significant difference in OS (P = .040) but not in DFS (P = .11), with all treatments given once every 2 weeks associated with the highest OS. This difference in OS seemed confined to patients with hormone receptor-negative/human epidermal growth factor receptor 2 (HER2) -negative tumors (P = .067), with no differences seen with hormone receptor-positive/HER2-negative (P = .90) or HER2-positive tumors (P = .40). CONCLUSION: Patients achieved a similar DFS with any of these regimens. Subset analysis suggests the hypothesis that once-every-2-weeks dosing may be best for patients with hormone receptor-negative/HER2-negative tumors.

RESUMO

OBJECTIVE: We sought to determine whether induction chemotherapy followed by concomitant chemoradiation (ICCR)-induced advanced neck disease regression could predict outcome, especially the need for complete neck dissection in patients with N2-3 stage IV head and neck cancer (HNC). METHODS: A retrospective study of 339 patients evaluated for treatment of stage IV HNC during the years 1988 to 1997 revealed 36 individuals with N2-3 cervical lymphadenopathy who were treated with ICCR. Responses to treatment, patterns of failure, and survival rates were analyzed. RESULTS: Primary and regional tumor regressions were complete in 21 patients (58%), partial in 9 (25%), and absent in 6 (17%); the corresponding local failure rates were 5%, 44%, and 33% (P < 0.02). The regional failure rates were 24%, 89%, and 83%, respectively (P < 0.001); distant failure rates were 10%, 0%, and 0% (P > 0.99). The estimated 2-year survival rates for complete and partial/nonresponders were 57% and 20%, respectively (P < 0.02). CONCLUSION: Patients with advanced regional metastases of HNC who respond completely to ICCR have an excellent chance for survival. However, such ICCR-induced complete regression of regional tumor cannot reliably predict ultimate neck disease control.

RESUMO

OBJECTIVE: To determine whether chemoradiation (CX) is as effective as surgery with postoperative radiotherapy (SX) for operable, locally advanced head and neck cancer (LAHNC). METHODS: A retrospective review of 78 patients with operable stage III or IV cancer of the upper aerodigestive tract who were treated by CX (n = 25) or SX (n = 53) during a 20-year period was undertaken. RESULTS: Fewer patients relapsed regionally when treated by SX than by CX (p = 0.006). On the other hand, there was no significant difference in local recurrence, distant metastasis, 2-year survival rate, or 5-year survival rate between the two patient groups. CONCLUSION: Our results suggesting that CX is not as effective as SX for patients with operable LAHNC calls for a randomized trial comparing CX to SX in such cases.

RESUMO

UNLABELLED: Triple negative or basal-like breast cancers lack expression of estrogen, progesterone and HER2neu receptors. There are no specific treatment guidelines for this group of patients, however, it has been postulated that their phenotypic and molecular similarity to BRCA-1 related cancers would confer sensitivity to certain cytotoxic agents like cisplatin (CDDP). The aim of the study was to retrospectively examine the clinical outcome at our institution of patients with metastatic breast cancer treated with CDDP and gemcitabine combination chemotherapy who had triple negative breast cancer compared to non-triple negative breast cancer. Thirty-six patients with metastatic breast cancer were treated with CDDP and gemcitabine combination chemotherapy, 17 of whom were triple negative (47%) and 19 were non-triple negative (53%). The median progression free survival for triple negative and non-triple negative metastatic breast cancer patients were 5.3 months and 1.7 months respectively (p = 0.058). By multivariate Cox proportional hazard model after adjusting for age, race and menopausal status the risk of progression was reduced by 47% for triple negative compared to non-triple negative metastatic breast cancer patients (HR = 0.53, p = 0.071). CONCLUSIONS: Our results suggest an improved outcome for metastatic triple negative breast cancer patients compared to non-triple negative breast cancer patients when treated with cisplatin and gemcitabine combination chemotherapy.

RESUMO

Thiamine deficiency can occur in any disease that results in inadequate intake or excessive loss of vitamin B1. In addition to increased thiamine consumption secondary to high cell turnover, cancer patients frequently have reduced oral intake as a direct result of their cancer or from cancer treatments. However, Wernicke encephalopathy (cerebral Beriberi), a clinical manifestation of thiamine deficiency, has rarely been associated with cancer patients. We report a case of Wernicke encephalopathy in a nonalcoholic patient with lymphoma. Although thiamine deficiency rarely potentiates clinical sequelae in cancer patients, it is important to recognize the risk and the clinical signs and manifestations so that prompt therapy can be initiated to reverse morbidity.

RESUMO

A 26-year old man presented with a 3-month history of a progressively enlarging palpable parieto-occipital mass. A CT scan indicated the lesion arose from the dura with bony destruction. A stealth assisted craniotomy was performed with the provisional diagnosis of osteoblastic meningioma. Further histopathologic analysis of the intracranial mass was consistent with leiomyosarcoma. Staging evaluation, including CT and PET scans, demonstrated no other sites of disease. Despite complete surgical resection and radiotherapy to the resection site, the disease recurred locally and systematically 5 months later. Primary intracranial mesenchymal tumors are rare and few cases have been previously reported. Outcomes have been universally poor and current therapeutic approaches appear to have only limited benefit.

RESUMO

PURPOSE: To assess the effect of cisplatin (CDDP) plus concurrent radiation therapy on hearing loss. METHODS: 451 patients with glioblastoma multiforme (GBM) were randomly assigned after surgery to: Arm A: Carmustine (BCNU) + standard radiation therapy (SRT); Arm B: BCNU + accelerated radiation therapy (ART: 160 cGy twice daily for 15 days); Arm C: CDDP + BCNU + SRT; or Arm D: CDDP + BCNU + ART. Patients on arms C and D received audiograms at baseline, and prior to the start of RT, and prior to cycles 3 and 6. Otologic toxicities were recorded at each visit. RESULTS: 56% of patients had hearing loss at baseline. 13% and 50% of patients experienced worsening ototoxicity after 1 year of treatment in arms A and B vs. C and D, respectively, with 13% of those on arms C and D experiencing significant ototoxicity (>or= grade 3) at 6 months. Increasing age was associated with an increased risk of ototoxicity. CONCLUSIONS: Increased exposure to CDDP increases the risk of ototoxicity over time. Older patients are more susceptible to hearing loss with CDDP. The low proportion of patients with clinically significant ototoxicity suggests that baseline screening is unnecessary in GBM patients.

RESUMO

PURPOSE: In patients with newly diagnosed glioblastoma multiforme, to determine whether cisplatin plus carmustine (BCNU) administered before and concurrently with radiation therapy (RT) improves survival compared with BCNU and RT and whether survival using accelerated RT (ART) is equivalent to survival using standard RT (SRT). PATIENTS AND METHODS: After surgery, patients were stratified by age, performance score, extent of surgical resection, and histology (glioblastoma v gliosarcoma) and then randomly assigned to arm A (BCNU plus SRT), arm B (BCNU plus ART), arm C (cisplatin plus BCNU plus SRT), or arm D (cisplatin plus BCNU plus ART). RESULTS: Four hundred fifty-one patients were randomly assigned, and 401 were eligible. Frequent toxicities included myelosuppression, vomiting, sensory neuropathy, and ototoxicity and were worse with cisplatin. There was no difference in toxicity between SRT and ART. Median survival times and 2-year survival rates for patients who received BCNU plus RT (arms A and B) compared with cisplatin, BCNU, and RT (arms C and D) were 10.1 v 11.5 months, respectively, and 11.5% v 13.7%, respectively (P = .19). Median survival times and 2-year survival rates for patients who received SRT (arms A and C) compared with ART (arms B and D) were 11.2 v 10.5 months, respectively, and 13.8% v 11.4%, respectively (P = .33). CONCLUSION: Cisplatin administered concurrently with BCNU and RT resulted in more toxicity but provided no significant improvement in survival. SRT and ART produced similar toxicity and survival.
