Promising initial trial of immunotherapy agent in anal cancer

A study of nivolumab (Opdivo) in patients with squamous cell carcinoma of the anal canal (SCCA), which recently presented findings at the 2016 World Congress on Gastrointestinal (GI) Cancer, is the first prospective trial to examine immunotherapy agents in the treatment of SCCA.

Approximately 80% to 95% of cases are linked to human papillomavirus (HPV) infection. "The role of HPV in the tumorigenesis of SCCA provides rationale for the use of immune checkpoint agents as a novel therapy for patients with a virally driven disease." noted lead author Cathy Eng, MD, professor of gastrointestinal medical oncology at the University of Texas MD Anderson Cancer Center and co-leader of MD Anderson's HPV-related Cancer Moon Shot.

Adjuvant combination therapy improves survival in pancreatic cancer

June 16, 2016 - The results from the ESPAC-4, a multicenter, international, open-label randomised controlled phase III trial of adjuvant combination chemotherapy of gemcitabine / capecitabine versus monotherapy gemcitabine in patients with resected pancreatic ductal adenocarcinoma show a statistically significant 2.5 months improvement in survival in favour of combination regimen. The results were presented in the oral abstract session on Gastrointestinal (Noncolorectal) Cancer by Dr John Neoptolemos during the ASCO Annual Meeting 2016 (3-7 June, Chicago US).

Gemcitabine is the standard of care in this setting. Previously, the ESPAC-3 trial compared adjuvant gemcitabine with 5-fluorouracil / folinic acid (5-FU/FA) for resected pancreatic cancer; gemcitabine regimen achieved similar survival with less toxicity. ESPAC-4 aimed to determine whether combination chemotherapy with gemcitabine / capecitabine improve survival compared to gemcitabine alone. Read more here.

HIV-positive patients more likely to lack cancer treatment

May 17, 2016 –A new study finds HIV-infected patients with cancer in the United States appear to be less likely to receive cancer treatment, regardless of insurance and other existing health conditions. The study, by researchers at the University of Utah, National Cancer Institute and the American Cancer Society, appears early online in Cancer.

Cancer is an increasingly common cause of morbidity and mortality among individuals infected with the human immunodeficiency virus (HIV). In the United States, cancer incidence rates in this population have increased since the introduction of highly active antiretroviral therapy (HAART). Cancer is now the second most common cause of death among HIV-infected individuals, after AIDS-related deaths. Read more here.

Anti-proliferative effect and predictive biomarkers to palbociclib in early breast cancer

May 12, 2016 - In this study, the investigators from the Institut Gustave Roussy, Villejuif, France aimed to identify if short-term preoperative palbociclib is associated with decreased proliferation and early biomarker changes in patients with early breast cancer. Untreated patients were randomised 3:1 to oral palbociclib 125 mg daily for 2 weeks until the day before the surgery vs no treatment.

Short-term preoperative palbociclib treatment in patients with early breast cancer significantly decreased Ki67; this effect depended on molecular subtypes and correlated with changes in pRB, suggesting that activity of palbociclib could be the main determinant of its short-term effect on proliferation.

Breast cancer genes may play a role in prostate cancer

According to three new studies, risk of developing aggressive and lethal prostate cancer "may be heavily influenced by gene mutations previously linked to breast and ovarian cancer in women." Thus, men in families with a history of breast cancer should undergo more intensive prostate cancer screening.  According to one study, men carrying the BRCA2 gene mutation found in breast cancer were 4 times more likely to already exhibit an advanced stage of prostate cancer when diagnosed.

Elevated bladder cancer risk in New England and arsenic in drinking water from private wells

On May 2, 2016 A new study has found that drinking water from private wells, particularly dug wells established during the first half of the 20th century, may have contributed to the elevated risk of bladder cancer that has been observed in Maine, New Hampshire, and Vermont for over 50 years. Other risk factors for bladder cancer, such as smoking and occupational exposures, did not explain the excess risk in this region.

Bladder cancer mortality rates have been elevated in northern New England for over half a century. The incidence of bladder cancer in Maine, New Hampshire, and Vermont has been about 20 percent higher than that in the United States overall. Read more here.

Cape Breton Cancer Centre introduces new breast cancer treatment method

The Cape Breton Cancer Centre is using a new technique called breath/hold to treat some breast cancer patients. It's a simple technique that requires the patient to take a deep breath and hold it for 20 to 30 seconds to allow a radiation beam to focus and more accurately hit its intended area.

The Nova Scotia Health Authority says the centre at the Cape Breton Regional Hospital is the first in Atlantic Canada to adopt the technique. "The heart comes very close to the chest wall and we are treating the chest wall, so when they hold their breath, it pushes the heart downwards and out of the radiation field," said Dr, Waseem Sharieff, a radiation oncologist at the centre.

New treatment target identified for key prostate cancer driver

On April 22, 2016 researchers have identified a potential alternative approach to blocking the activity of a key molecular driver of an advanced form of prostate cancer, called androgen-independent or castration-resistant prostate cancer.

In prostate cancer cell lines and in several mouse models of prostate cancer, treatment with drug-like small molecules that target a protein called ROR-γ disrupted the activity of the androgen receptor (AR), the researchers showed. Signaling through AR is the chief means by which prostate cancer cells grow and spread. Read more here.
