VIDEO: HPV testing predicted to displace most Pap smears
CHICAGO – Dr. Laurie J. McKenzie, who is a member of the ACOG Committee on the Scientific Program and the medical faculties of the University of Texas and Baylor College of Medicine, Houston, interviews Dr. Michael M. Frumovitz of the University of Texas MD Anderson Cancer Center, Houston, the presenter of the John I. Brewer Memorial Lecture on cervical cancer screening.
During a video interview at the annual meeting of the American Congress of Obstetricians and Gynecologists, they discuss reductions in cervical dysplasia that have already been seen with HPV vaccination in Australia and note the barriers to HPV vaccination in the United States. Dr. Frumovitz predicts that HPV testing will ultimately replace Pap smears for primary screening in most cases and discusses the potential for high-resolution microendoscopy to change how cervical lesions are diagnosed and treated.

Ethnic differences in stem cell transplants may be narrowing
NEW ORLEANS – The gap appears to be narrowing between white European patients and European patients of other ethnicities regarding times to stem cell transplant and ability to find a matched donor, based on a study conducted in the United Kingdom.
In the study, non-white northern European patients were less likely than white northern European patients to have a fully-matched donor available. Transplant was ultimately achieved by 62% of white and 56% of nonwhite patients in a four-center study of 332 leukemia and lymphoma patients treated in the United Kingdom in concert with Anthony Nolan, the United Kingdom’s blood cancer charity and bone marrow register. Non-white patients comprised 25% of the patient population, Dr. Robert Lown reported during a press conference held at the annual meeting of the American Society of Hematology.
"The use of cord blood and haploidentical transplants is ‘leveling the playing field’ for non-white patients seeking transplants other than with an HLA-identical sibling," said Dr. Lown of the Royal Marsden Hospital, London, and of Anthony Nolan.
Just 20% of non-white patients in the study had a fully-matched donor available, while 69% of white northern European patients did. A suitable donor was identified, however, for 96% of the white European patients and 61% of patients of other ethnicities. Ultimately, transplant was achieved by 62% of white and 56% of other ethnicity patients. Average time to transplant was 110 days for white patients and 132 days for patients of other ethnicities, he said.
The results reflect improvements since a Dutch study of patients treated from 1996-2000 found that 32% of nonwhite and 59% of white northern Europeans achieved transplants. Typically, those patients who could not find a donor were either not transplanted or used less suitable donors, an option associated with more complications and poorer prognosis, he said.
The number of donors listed in registries has expanded, and new sources of stem cells, like cord blood and haploidentical transplantation, are available, Dr. Lown said. Few studies before this one have examined how these changes have affected the ability of transplant centers to get patients to transplant.
The trial results may not reflect general clinical experience, however, Dr. Lown said. Anthony Nolan uses an expert graft identification and advisory service to optimize donor selection and determine which patients are unlikely to find suitable donors. This practice allows timely use of cord blood and haploidentical transplants, Dr. Lown said.
The Anthony Nolan Research Institute sponsored the study. Dr. Lown did not disclose any financial conflicts of interest.

Nivolumab activity is durable in advanced melanoma
CHICAGO – Nivolumab, an investigational PD-1 inhibitor, shrank tumors by at least 30% in 33 of 107 pretreated patients with metastatic melanoma, based on results from an expanded phase I trial reported at the annual meeting of the American Society of Clinical Oncology.
An additional 11% of patients had prolonged stable disease or non-conventional, immune-related response profiles.
The findings build on favorable initial results reported at last year’s annual meeting for nivolumab in melanoma, renal cell carcinoma, and nonsmall cell lung cancer. The latest results in melanoma patients at follow-ups as long as 2 years indicate no new safety signals with nivolumab, which was associated with a 21% rate of grade 3-4 events. The rate of severe immune-related adverse events was 5%, and there were no cases of grade 3 or higher pneumonitis.
Median overall survival was nearly 17 months with nivolumab, with a 2-year survival rate of 43%. Median overall survival with vemurafenib (Zelboraf) is 16 months and with ipilimumab (Yervoy) is 10 months, with 2-year survival rates of 24% to 33% with ipilimumab, according to Dr. Mario Sznol, who presented the results from the phase I trial.
"We’re very excited that there is potential for even more activity [with nivolumab] in combination with other drugs," said Dr. Sznol, professor of medicine (medical oncology) at the Yale Cancer Center in New Haven, Conn.
Responses were seen at all five dose levels tested (0.1, 0.3, 1, 3, and 10 mg/kg), with a 41% objective response rate at the 3 mg/kg dose, which has been selected for evaluation in phase III studies.
Median overall survival across all doses of nivolumab was 16.8 months. It reached 20.3 months for the 3 mg/kg dose. The 1-year survival rate was 62% and the 2-year survival rate, 43%.
Patients in the nivolumab trial were representative of typical patients with advanced melanoma, Dr. Sznol said. All patients in the study had disease that worsened despite prior standard systemic therapies, 25% of them had three or more prior therapies and 63% had two or more prior therapies.
All had ECOG performance standards of 0 or 1. Patients received up to 12 cycles of treatment, with four doses of nivolumab per cycle, until discontinuation criteria were met.
Response has persisted after stopping treatment in 17 of 33 patients, with 12 of the 17 continuing to respond for at least 4 months, Dr. Sznol said.
The overall objective response rate included partial and complete responses. Dr. Sznol acknowledged that just one patient had a verified complete response to nivolumab and four others had near complete responses at 2 years. Historical response rates to immunotherapy drugs are 5%-10% in advanced melanoma, he noted, which is lower than the 30% response seen in these pretreated patients.
"I have seen a few relapses after 2 years of response, but some patients continue to do well at 4 years. One patient who has been off nivolumab for 2 years continues to do well at over 4 years," Dr. Sznol commented during a question and answer session.
To define the best candidates for nivolumab, molecular markers need to be identified to predict probable response, he added. As nivolumab is a PD-1 inhibitor, one potential marker is the protein PD-L1 on the surface of tumor cells, which is being studied in several other clinical trials.
The research was supported by Bristol-Myers Squibb. Dr. Sznol disclosed that he serves in a consultant or advisory role with Bristol-Myers Squibb.
