The US Food and Drug Administration (FDA) has granted breakthrough therapy designation for pembrolizumab (Keytruda) to treat patients with relapsed or refractory classical Hodgkin lymphoma (cHL).
Pembrolizumab is a monoclonal antibody that binds to the PD-1 receptor and blocks its interaction with PD-L1 and PD-L2, releasing PD-1 pathway-mediated inhibition of the immune response, including the antitumor immune response.
The FDA’s breakthrough therapy designation is intended to expedite the development and review of new therapies for serious or life threatening conditions, which have shown encouraging early clinical results demonstrating substantial improvement on a clinically significant endpoint over available therapies.
The breakthrough designation for pembrolizumab in cHL is based on data from the phase 1b KEYNOTE-013 trial and the phase 2 KEYNOTE-087 trial.
Findings from the KEYNOTE-013 study were presented at ASH 2014 (in patients with cHL) and ASH 2015 (in primary mediastinal large B-cell lymphoma).
Data from KEYNOTE-087 will be presented at an upcoming medical meeting, according to Merck, the company developing pembrolizumab.
Pembrolizumab also has breakthrough designation from the FDA as a treatment for advanced melanoma, advanced non-small cell lung cancer, and advanced colorectal cancer.
The drug is already FDA-approved to treat melanoma and non-small cell lung cancer. Pembrolizumab is administered at a dose of 2 mg/kg as an intravenous infusion over 30 minutes every 3 weeks for the approved indications.

PD-1 inhibitor granted priority review for cHL

The US Food and Drug Administration (FDA) has granted priority review to a supplemental biologics license application seeking to expand use of the PD-1 inhibitor nivolumab (Opdivo) to patients with previously treated classical Hodgkin lymphoma (cHL).
A priority review designation means the FDA’s goal is to take action on an application within 6 months, rather than the 10 months typically taken for a standard review.
To grant an application priority review, the FDA must believe the drug would provide a significant improvement in the treatment, diagnosis, or prevention of a serious condition.
About nivolumab
Nivolumab is an inhibitor that binds to the checkpoint receptor PD-1, which is expressed on activated T cells. The drug prevents PD-L1 and PD-L2 from binding, thereby preventing the PD-1 pathway’s suppressive signaling on the immune system, including interference with an anti-tumor immune response.
Nivolumab is being developed by Bristol-Myers Squibb. The drug currently has regulatory approval in 48 countries.
In the US, nivolumab is approved—both as a single agent and in combination—to treat certain patients with melanoma, non-small-cell lung cancer, or advanced renal cell carcinoma.
According to Bristol-Myers Squibb, nivolumab has the potential to become first PD-1 inhibitor approved for a hematologic malignancy in the US.
The supplemental biologics license application for nivolumab included data from the phase 2 trial CheckMate 205. In this ongoing trial, researchers are evaluating nivolumab in patients with relapsed or refractory cHL who have received an autologous stem cell transplant and brentuximab vedotin.
Data from this trial are expected to be presented at a medical meeting later this year.
The FDA previously granted nivolumab breakthrough therapy designation for cHL. The FDA’s breakthrough therapy designation is intended to expedite the development and review of drugs for serious or life-threatening conditions.

FDG-PET guides need for eBEACOPP in advanced Hodgkin’s
Using FDG-PET (fluorodeoxyglucose positron emission tomography) imaging to gauge treatment response after the first two rounds of ABVD therapy helps to determine which patients with advanced Hodgkin’s lymphoma should be switched to a more aggressive eBEACOPP regimen, according to the results of the Southwest Oncology Group (SWOG) S0816 study.
In this large U.S. trial of PET scanning to guide treatment approach in people with high-risk stage II or stage III-IV Hodgkin’s lymphoma, progression-free survival at 2 years for those with early interim positive PET scans was 64%, which is much higher than the expected progression-free survival of 15%-30%, according to Dr. Oliver Press, a SWOG member at Fred Hutchinson Cancer Research Center and the lead author of study, which was published ahead of print in the Journal of Clinical Oncology (2016 April 11. doi: 10.1200/JCO.2015.63.1119).
In addition, just 20% of patients in the trial were exposed to eBEACOPP, which usually results in infertility, can cause sustained heart or lung damage, and increases the risk of secondary cancers.
Researchers recruited 358 Hodgkin’s patients to the trial and were able to evaluate 331 of them. All trial volunteers were given two rounds of standard ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) chemotherapy, followed by a PET scan. If the scan was negative, patients received four more cycles of ABVD. If the scan was positive, with a Deauville score of 4-5, they were advised to switch to eBEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone), a seven-drug combination used in Europe. Of 60 patients with positive interim PET scans, 11 patients declined to switch, and 49 switched as planned to six cycles of eBEACOPP.
With a median follow-up of nearly 40 months, the Kaplan-Meier estimate for 2-year overall survival was 98%, and the 2-year estimate for progression-free survival was 79%. In the subset of patients who had positive PET scans after two cycles of ABVD, the 2-year estimate for progression-free survival was 64%, more than double the expected remission rate.
At least seven phase II and III cooperative group studies are underway testing this approach in advanced-stage Hodgkin’s lymphoma, the researchers wrote. “We hope that in the future, molecular biomarker studies at initial diagnosis, or the combination of biomarkers and molecular imaging, may define patients who require more intense therapy with eBEACOPP or other novel targeted drugs with greater accuracy than is achievable with current technology.”
The study was funded by the National Cancer Institute, the David and Patricia Giuliani Family Foundation, the Lymphoma Foundation, the Adam Spector Fund for Hodgkin Research, and the Ernest & Jeanette Dicker Charitable Foundation.

PET-guided chemo improves PFS in advanced HL

Using PET imaging to guide chemotherapy can improve outcomes for patients with advanced Hodgkin lymphoma (HL), according to research published in the Journal of Clinical Oncology.
The study indicated that PET-guided treatment can improve progression-free survival (PFS) among patients who do not achieve remission with 2 cycles of ABVD.
The results also suggested the approach can spare some patients unnecessary toxicity.
“The goal of cancer treatment is to cure as many people as possible with as little toxicity as possible,” said study author Oliver Press, MD, PhD, of the Fred Hutchinson Cancer Research Center in Seattle, Washington.
“We found a promising way to do that by tailoring treatment to Hodgkin patients, an approach which could lead to a new standard of care.”
Dr Press and his colleagues began this study with 358 HIV-negative patients with advanced HL, but only 336 of them were eligible and evaluable at baseline.
The patients’ median age was 32 (range, 18 to 60). Fifty-two percent had stage III disease, 48% had stage IV, 49% had an International Prognostic Score of 0 to 2, and 51% had a score of 3 to 7.
All of the patients received ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) and underwent a PET scan to gauge their response after 2 cycles (PET2).
If the scan was negative, patients received a final 4 cycles of ABVD. If the scan was positive, patients received 6 cycles of eBEACOPP (escalated bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisolone).
Central review of the PET2 scan was performed in 331 patients. Most (82%, n=271) had a negative scan.
Forty-nine of the 60 PET2-positive patients went on to receive eBEACOPP as planned, but 11 patients declined.
The median follow-up was 39.7 months. For the entire study cohort, the estimated 2-year overall survival was 98%, and the estimated 2-year PFS was 79%.
The 2-year estimated PFS was 82% for PET2-negative patients and 64% for PET2-positive patients. The researchers noted that, typically, if HL patients have a positive PET scan after 2 rounds of ABVD, their expected 2-year PFS ranges from about 15% to 30%.
The researchers also pointed out that eBEACOPP was significantly more toxic than ABVD. The incidence of grade 4/5 toxicities was 85.7% and 36.7%, respectively (P<0.001).
There were 3 treatment-related deaths—1 in the ABVD group and 2 in the eBEACOPP group. And 6 patients developed secondary malignancies—3 in each group—including 2 non-Hodgkin lymphomas, 2 kidney cancers, 1 melanoma, and 1 skin cancer.
“[O]nly 20% of the patients in our trial were exposed to eBEACOPP, which means [most patients] weren’t exposed to its bad effects,” said Jonathan Friedberg, MD, of the University of Rochester Medical Center in Rochester, New York.
“That’s important because many people diagnosed with Hodgkin lymphoma are in their 20s and 30s and want to have children. This response-adapted therapy would ensure that the people who need the more toxic drugs receive them and would spare others from infertility and serious toxicities.”

Combos produce similar 10-year OS, PFS in HL

Long-term results of the HD2000 trial reveal similar survival rates in patients with previously untreated, aggressive Hodgkin lymphoma (HL) who received 3 different combination treatment regimens.
At 10 years of follow-up, there was no significant difference in overall survival (OS) or progression-free survival (PFS) whether patients received ABVD, BEACOPP, or CEC.
However, patients who received ABVD were significantly less likely than those who received BEACOPP or CEC to develop second malignancies.
Francesco Merli, MD, of Istituto di Ricovero e Cura a Carattere Scientifico (IRCCS) in Italy, and his colleagues reported these results in the Journal of Clinical Oncology.
The trial enrolled 307 patients with advanced-stage HL. Patients were randomized to receive 1 of 3 treatment regimens:
- Six cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine)
- Four escalated plus 2 standard cycles of BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone)
- Six cycles of CEC (cyclophosphamide, lomustine, vindesine, melphalan, prednisone, epidoxorubicin, vincristine, procarbazine, vinblastine, and bleomycin).
Some patients also received radiotherapy, but there was no significant difference in the proportion of patients receiving radiotherapy across the treatment arms—46% in the ABVD arm, 44% in the BEACOPP arm, and 43% in the CEC arm (P=0.871).
Results
At the end of all therapy, the complete response rate was 84% with ABVD, 91% with BEACOPP, and 83% with CEC.
There were 84 patients who did not achieve a complete response, and salvage data were available for 73 of these patients. Three patients (4%) died before salvage therapy could begin, 26 (36%) received conventional chemotherapy, 40 (55%) received a hematopoietic stem cell transplant, and 4 (5%) received radiotherapy.
The median follow-up was 120 months (range, 4 to 169 months), and 295 patients were evaluable.
In a previous analysis, at a median follow-up of 42 months, patients who received BEACOPP had superior PFS compared to patients who received ABVD.
However, in the current analysis, there was no significant difference in PFS between the 3 treatment arms. The 10-year PFS was 69% in the ABVD arm, 75% in the BEACOPP arm, and 76% in the CEC arm (P=0.471).
Likewise, there was no significant difference in OS between the treatment arms. The 10-year OS was 85% in the ABVD arm, 84% in the BEACOPP arm, and 86% in the CEC arm (P=0.892).
There were a total of 13 second malignancies—1 in the ABVD arm and 6 each in the BEACOPP and CEC arms.
The cumulative risk of developing a second malignancy at 10 years was 0.9% in the ABVD arm, 6.6% in the BEACOPP arm, and 6% in the CEC arm. So the risk with either BEACOPP or CEC was significantly higher than with ABVD (P=0.027 and 0.02, respectively).
The researchers said these results suggest BEACOPP provides better disease control than ABVD, but this benefit is counterbalanced by a higher rate of late major events with BEACOPP, particularly second malignancies, which resulted in patient deaths.
So the team concluded that BEACOPP is a viable treatment option for advanced HL, but it should not be considered the standard for all patients because 70% of these patients may be cured with ABVD and limited radiotherapy. A careful assessment of the risk-benefit ratio of the initial treatment choice is warranted.

The trial enrolled 307 patients with advanced-stage HL. Patients were randomized to receive 1 of 3 treatment regimens:
- Six cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine)
- Four escalated plus 2 standard cycles of BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone)
- Six cycles of CEC (cyclophosphamide, lomustine, vindesine, melphalan, prednisone, epidoxorubicin, vincristine, procarbazine, vinblastine, and bleomycin).
Some patients also received radiotherapy, but there was no significant difference in the proportion of patients receiving radiotherapy across the treatment arms—46% in the ABVD arm, 44% in the BEACOPP arm, and 43% in the CEC arm (P=0.871).
Results
At the end of all therapy, the complete response rate was 84% with ABVD, 91% with BEACOPP, and 83% with CEC.
There were 84 patients who did not achieve a complete response, and salvage data were available for 73 of these patients. Three patients (4%) died before salvage therapy could begin, 26 (36%) received conventional chemotherapy, 40 (55%) received a hematopoietic stem cell transplant, and 4 (5%) received radiotherapy.
The median follow-up was 120 months (range, 4 to 169 months), and 295 patients were evaluable.
In a previous analysis, at a median follow-up of 42 months, patients who received BEACOPP had superior PFS compared to patients who received ABVD.
However, in the current analysis, there was no significant difference in PFS between the 3 treatment arms. The 10-year PFS was 69% in the ABVD arm, 75% in the BEACOPP arm, and 76% in the CEC arm (P=0.471).
Likewise, there was no significant difference in OS between the treatment arms. The 10-year OS was 85% in the ABVD arm, 84% in the BEACOPP arm, and 86% in the CEC arm (P=0.892).
There were a total of 13 second malignancies—1 in the ABVD arm and 6 each in the BEACOPP and CEC arms.
The cumulative risk of developing a second malignancy at 10 years was 0.9% in the ABVD arm, 6.6% in the BEACOPP arm, and 6% in the CEC arm. So the risk with either BEACOPP or CEC was significantly higher than with ABVD (P=0.027 and 0.02, respectively).
The researchers said these results suggest BEACOPP provides better disease control than ABVD, but this benefit is counterbalanced by a higher rate of late major events with BEACOPP, particularly second malignancies, which resulted in patient deaths.
So the team concluded that BEACOPP is a viable treatment option for advanced HL, but it should not be considered the standard for all patients because 70% of these patients may be cured with ABVD and limited radiotherapy. A careful assessment of the risk-benefit ratio of the initial treatment choice is warranted.

Long-term results of the HD2000 trial reveal similar survival rates in patients with previously untreated, aggressive Hodgkin lymphoma (HL) who received 3 different combination treatment regimens.
At 10 years of follow-up, there was no significant difference in overall survival (OS) or progression-free survival (PFS) whether patients received ABVD, BEACOPP, or CEC.
However, patients who received ABVD were significantly less likely than those who received BEACOPP or CEC to develop second malignancies.

Dual inhibitor shows early promise for DLBCL
The small-molecule inhibitor CUDC-907 can provide disease control in patients with relapsed or refractory lymphoma and multiple myeloma (MM), according to researchers.
In a phase 1 trial, CUDC-907 produced responses in a small number of patients with diffuse large B-cell lymphoma (DLBCL).
And more than half of patients had stable disease while on CUDC-907, including those with MM, DLBCL, Hodgkin lymphoma (HL), and other lymphomas.
However, a majority of patients in this trial—84%—discontinued treatment due to confirmed progressive disease or signs of progression.
These results were published in The Lancet. The trial was sponsored by Curis, Inc., the company developing CUDC-907, and the Leukemia and Lymphoma Society.
“The data from the phase 1 monotherapy trial for CUDC-907, especially in heavily pretreated patients with relapsed/refractory DLBCL are very encouraging, and we look forward to data emerging from the current phase 2 trial in patients with MYC-altered DLBCL,” said study author Anas Younes, MD, of the Memorial Sloan Kettering Cancer Center in New York, New York.
CUDC-907 is an oral, dual inhibitor of class I and II histone deacetylases (HDACs), as well as class I PI3K enzymes. Specifically, CUDC-907 is designed to inhibit HDACs 1, 2, 3, 6, and 10 and PI3K-alpha, delta, and beta isoforms.
Between Jan 23, 2013, and July 27, 2015, the phase 1 trial of CUDC-907 enrolled 44 patients who were refractory to or had relapsed after 2 or more previous regimens. The patients’ median age was 63 (range, 22-83), and they had received a median of 5 prior treatments (range, 2-10).
Four patients had MM, 12 had HL, and 12 had DLBCL. The remaining 16 patients had other types of lymphoma, including lymphoplasmacytic lymphoma (n=3), small lymphocytic lymphoma (n=3), mantle cell lymphoma (n=3), follicular lymphoma (n=2), T-cell lymphoma (n=2), marginal zone lymphoma (n=1), Burkitt lymphoma (n=1), and gray zone lymphoma (n=1).
Treatment
CUDC-907 was given in a standard 3 + 3 dose-escalation design at 4 different dosing schedules—once daily, twice weekly, 3 times weekly, and daily for 5 days followed by a 2-day break (5/2)—in 21-day cycles.
Patients continued to receive CUDC-907 until disease progression or other treatment discontinuation criteria were met. The primary objective was to determine the maximum tolerated dose (MTD) and recommended phase 2 dose.
Ten patients were sequentially assigned to CUDC-907 once-daily (MTD 60 mg), 12 to twice-weekly (MTD 150 mg), 15 to 3-times-weekly (MTD 150 mg), and 7 to the 5/2 dosing schedule (MTD 60 mg).
Safety
Four dose-limiting toxicities (DLTs) occurred in 3 of 40 DLT-evaluable patients. The DLTs were diarrhea and hyperglycemia in 1 patient on 60 mg once daily, hyperglycemia in 1 patient on 150 mg twice weekly, and diarrhea in 1 patient on 150 mg 3 times weekly. There were no DLTs in patients on the 5/2 schedule.
The incidence of grade 3 or higher adverse events (AEs) was 43% (19/44). The most common of these AEs were thrombocytopenia (20%, n=9), neutropenia (7%, n=3), and hyperglycemia (7%, n=3).
Twenty-five percent of patients (11/44) had serious AEs. Three of these events were considered treatment-related. They were epistaxis and the DLTs of diarrhea and hyperglycemia.
AEs led to dose reductions in 6 patients (14%) and treatment discontinuation in 7 patients (16%).
Efficacy
Thirty-seven patients were evaluable for response, and 5 of these patients responded (14%). All responses—2 complete and 3 partial responses—occurred in patients with DLBCL.
Twenty-one of the response-evaluable patients (57%) had stable disease. This included 1 patient with DLBCL, 2 with MM, 8 with HL, and 10 with the “other” types of lymphoma.
The remaining 11 patients progressed (30%)—3 with DLBCL, 2 with MM, 2 with HL, and 4 with other lymphomas.
Thirty-seven patients (84%) discontinued CUDC-907 because of progressive disease or clinical signs of progressive disease at the data cutoff.
Based on the clinical activity of CUDC-907 in patients with relapsed/refractory DLBCL, particularly those with MYC alterations, Curis has initiated a phase 2 trial of the drug in these patients. The recommended phase 2 dose is 60 mg on the 5/2 dosing schedule.

Germline mutations linked to hematologic malignancies
A new study suggests mutations in the gene DDX41 occur in families where hematologic malignancies are common.
Previous research showed that both germline and acquired DDX41 mutations occur in families with multiple cases of late-onset myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML).
The new study, published in Blood, has linked germline mutations in DDX41 to chronic myeloid leukemia and lymphomas as well.
“This is the first gene identified in families with lymphoma and represents a major breakthrough for the field,” said study author Hamish Scott, PhD, of the University of Adelaide in South Australia.
“Researchers are recognizing now that genetic predisposition to blood cancer is more common than previously thought, and our study shows the importance of taking a thorough family history at diagnosis.”
To conduct this study, Dr Scott and his colleagues screened 2 cohorts of families with a range of hematologic disorders (malignant and non-malignant). One cohort included 240 individuals from 93 families in Australia. The other included 246 individuals from 198 families in the US.
In all, 9 of the families (3%) had germline DDX41 mutations.
Three families carried the recurrent p.D140Gfs*2 mutation, which was linked to AML.
One family carried a germline mutation—p.R525H, c.1574G.A—that was previously described only as a somatic mutation at the time of progression to MDS or AML. In the current study, the mutation was again linked to MDS and AML.
Five families carried novel DDX41 mutations.
One of these mutations was a germline substitution—c.435-2_435-1delAGinsCA—that was linked to MDS in 1 family.
Two families had a missense start-loss substitution—c.3G.A, p.M1I—that was linked to MDS, AML, chronic myeloid leukemia, and non-Hodgkin lymphoma.
One family had a DDX41 missense variant—c.490C.T, p.R164W. This was linked to Hodgkin and non-Hodgkin lymphoma (including 3 cases of follicular lymphoma). There was a possible link to multiple myeloma as well, but the diagnosis could not be confirmed.
And 1 family had a missense mutation in the helicase domain—p.G530D—that was linked to AML.
“DDX41 is a new type of cancer predisposition gene, and we are still investigating its function,” Dr Scott noted.
“But it appears to have dual roles in regulating the correct expression of genes in the cell and also enabling the immune system to respond to threats such as bacteria and viruses, as well as the development of cancer cells. Immunotherapy is a promising approach for cancer treatment, and our research to understand the function of DDX41 will help design better therapies.”

Study results support screening of childhood HL survivors
A new study indicates that early screening can reduce the risk of death from breast cancer among female survivors of childhood Hodgkin lymphoma (HL) who received chest radiation.
Researchers found evidence to suggest that starting mammograms at age 25 can reduce the risk of breast cancer death among these patients, but using MRI can reduce the risk further.
Unfortunately, both methods come with a risk of false-positive results.
David Hodgson, MD, of the University of Toronto in Canada, and his colleagues reported these findings in the Journal of the National Cancer Institute.
Dr Hodgson estimates there are thousands of HL survivors in North America treated throughout the 1990s and later who received chest radiation and are unaware they are at risk of breast cancer and eligible for early screening.
“Many of these are women who received radiotherapy to more normal tissue or at higher doses than are used currently,” he said. “But even for more recently treated patients, screening should reduce the risk of breast cancer death.”
For this study, Dr Hodgson and his colleagues gathered published information from dozens of studies about the risk of developing breast cancer in childhood HL survivors, the accuracy of different forms of breast cancer screening, and the rates at which women agree to be screened when asked.
Using mathematical models, the researchers used these data to quantify the effectiveness of starting screening early—at age 25.
The team found that, using mammography, about 260 survivors of childhood HL would need to be invited to have early breast cancer screening to prevent 1 breast cancer death.
However, the use of MRI for screening improved the effectiveness considerably. It reduced the number of women needing screening to prevent 1 breast cancer death to less than 80.
For HL survivors treated at age 15, the absolute risk of breast cancer mortality by age 75 was predicted to decrease from 16.65% with no early screening to 16.28% with annual mammography, 15.40% with annual MRI, 15.38% with same-day annual mammography and MRI, and 15.37% with alternating mammography and MRI every 6 months.
Dr Hodgson cautioned that there is a risk of false-positive screening results, particuarly with MRI, given that the method can detect many changes in breast tissue, most of which are not cancer.
The data suggested that, from age 25 to 75, at least one false-positive result would occur in 48% of women screened with mammography, 74% screened with MRI alone, and 79% screened with both methods.
The number of false-positives per 1000 screens would be 29.98 with mammography, 71.71 with MRI, and 99.52 with either same-day mammography and MRI or alternating mammography and MRI.
“So this is important for patients to know and for physicians to counsel patients about because it’s stressful for a patient to be called back about suspicious findings,” Dr Hodgson said.

David Hodgson, MD, of the University of Toronto in Canada, and his colleagues reported these findings in the Journal of the National Cancer Institute.
Dr Hodgson estimates there are thousands of HL survivors in North America treated throughout the 1990s and later who received chest radiation and are unaware they are at risk of breast cancer and eligible for early screening.
“Many of these are women who received radiotherapy to more normal tissue or at higher doses than are used currently,” he said. “But even for more recently treated patients, screening should reduce the risk of breast cancer death.”
For this study, Dr Hodgson and his colleagues gathered published information from dozens of studies about the risk of developing breast cancer in childhood HL survivors, the accuracy of different forms of breast cancer screening, and the rates at which women agree to be screened when asked.
Using mathematical models, the researchers used these data to quantify the effectiveness of starting screening early—at age 25.
The team found that, using mammography, about 260 survivors of childhood HL would need to be invited to have early breast cancer screening to prevent 1 breast cancer death.
However, the use of MRI for screening improved the effectiveness considerably. It reduced the number of women needing screening to prevent 1 breast cancer death to less than 80.
For HL survivors treated at age 15, the absolute risk of breast cancer mortality by age 75 was predicted to decrease from 16.65% with no early screening to 16.28% with annual mammography, 15.40% with annual MRI, 15.38% with same-day annual mammography and MRI, and 15.37% with alternating mammography and MRI every 6 months.
Dr Hodgson cautioned that there is a risk of false-positive screening results, particuarly with MRI, given that the method can detect many changes in breast tissue, most of which are not cancer.
The data suggested that, from age 25 to 75, at least one false-positive result would occur in 48% of women screened with mammography, 74% screened with MRI alone, and 79% screened with both methods.
The number of false-positives per 1000 screens would be 29.98 with mammography, 71.71 with MRI, and 99.52 with either same-day mammography and MRI or alternating mammography and MRI.
“So this is important for patients to know and for physicians to counsel patients about because it’s stressful for a patient to be called back about suspicious findings,” Dr Hodgson said.

A new report suggests African Americans (AAs) have significantly lower rates of most hematologic malignancies than non-Hispanic white (NHW) individuals in the US.
AAs of both sexes had significantly lower rates of leukemia, Hodgkin lymphoma (HL), and non-Hodgkin lymphoma (NHL) than NHWs, but the rate of myeloma was significantly higher among AAs.
The death rates for these malignancies followed the same patterns, with the exception of HL. There was no significant difference in HL mortality between AAs and NHWs of either sex.
These findings can be found in the report, “Cancer Statistics for African Americans, 2016,” appearing in CA: A Cancer Journal for Clinicians.
To compile this report, the researchers used data from the Surveillance, Epidemiology, and End Results program and the Centers for Disease Control and Prevention’s National Program of Cancer Registries.
Incidence
For part of the report, the researchers compared the incidence of cancers between AAs and NHWs (divided by gender) for the period from 2008 to 2012.
Among females, the incidence of leukemia was 8.6 per 100,000 in AAs and 10.7 per 100,000 in NHWs (P<0.05). Among males, the incidence was 13.2 per 100,000 in AAs and 17.7 per 100,000 in NHWs (P<0.05).
The incidence of HL in females was 2.4 per 100,000 in AAs and 2.7 per 100,000 in NHWs (P<0.05). The incidence of HL in males was 3.2 per 100,000 in AAs and 3.4 per 100,000 in NHWs (P<0.05).
The incidence of NHL in females was 12.0 per 100,000 in AAs and 16.6 per 100,000 in NHWs (P<0.05). The incidence of NHL in males was 17.2 per 100,000 in AAs and 24.1 per 100,000 in NHWs (P<0.05).
The incidence of myeloma in females was 11.1 per 100,000 in AAs and 4.3 per 100,000 in NHWs (P<0.05). The incidence of myeloma in males was 14.8 per 100,000 in AAs and 7.0 per 100,000 in NHWs (P<0.05).
Mortality
The researchers also compared cancer mortality between AAs and NHWs (divided by gender) for the period from 2008 to 2012.
The death rate for female leukemia patients was 4.8 per 100,000 in AAs and 5.4 per 100,000 in NHWs (P<0.05). The death rate for male leukemia patients was 8.1 per 100,000 in AAs and 9.9 per 100,000 in NHWs (P<0.05).
The death rate for female HL patients was 0.3 per 100,000 for both AAs and NHWs. The death rate for male HL patients was 0.4 per 100,000 for AAs and 0.5 per 100,000 in NHWs (not significant).
The death rate for female NHL patients was 3.6 per 100,000 in AAs and 5.0 per 100,000 in NHWs (P<0.05). The death rate for male NHL patients was 5.9 per 100,000 in AAs and 8.3 per 100,000 in NHWs (P<0.05).
The death rate for female myeloma patients was 5.4 per 100,000 in AAs and 2.4 per 100,000 in NHWs (P<0.05). The death rate for male myeloma patients was 7.8 per 100,000 in AAs and 4.0 per 100,000 in NHWs (P<0.05).
The researchers noted that the reasons for the higher rates of myeloma and myeloma death among AAs are, at present, unknown.

Study reveals subgroups of AYAs more likely to die of HL

A new study indicates that race, insurance status, and socioeconomic status (SES) impact survival in adolescents and young adults (AYAs) with Hodgkin lymphoma (HL).
Researchers found evidence to suggest that patients diagnosed with HL between the ages of 15 and 39 are less likely to survive the disease if they are black, Hispanic, have no insurance or public health insurance, or live in a neighborhood with low SES.
Theresa H.M. Keegan, PhD, MS, of the UC Davis Comprehensive Cancer Center in Sacramento, California, and her colleagues conducted this research and reported the results in Cancer Epidemiology, Biomarkers & Prevention.
Dr Keegan and her colleagues studied data from 9353 patients in the California Cancer Registry who were between 15 and 39 years old when they were diagnosed with HL between 1988 and 2011.
The team examined the impact of race/ethnicity, neighborhood SES, and health insurance on mortality.
The researchers found that AYAs diagnosed with early stage HL were twice as likely to die if they resided in a lower SES neighborhood.
Subjects were also twice as likely to die from HL if they had public health insurance or were uninsured, regardless of whether they were diagnosed at an early stage or a late stage.
Black AYA patients were 68% more likely to die of HL than non-Hispanic white patients, whether they were diagnosed at an early stage or a late stage.
And Hispanic AYA patients diagnosed at a late stage were 58% more likely than non-Hispanic white patients to die of HL, but there was no significant disparity for Hispanic patients diagnosed at an early stage.
“Identifying and reducing barriers to recommended treatment and surveillance in these AYAs at much higher risk of mortality is essential to ameliorating these survival disparities,” Dr Keegan said.
However, she and her colleagues noted that this study had limitations. The researchers were able to identify the first course of treatment but did not have specific details on the treatment that followed the initial period.
In addition, health insurance status at the time of diagnosis was not available for patients who were diagnosed before 2001, and the researchers did not have information on changes in patients’ insurance status that may have occurred after their initial treatment.
