Stem Cell Vaccine Carries Potential as Mesothelioma Treatment

Researchers at the Stanford University School of Medicine believe a patient-specific stem cell vaccine could become part of mesothelioma treatment — and possibly prevention — in the future. The belief stems from their recent study that demonstrated a consistent immunologic response with genetically-altered stem cells in laboratory mice carrying particular cancer cells. “This could potentially play a role for a large group of — if not all — cancers,” Dr. Joseph Wu, director of the Stanford Cardiovascular Institute, told Asbestos.com. “We envision it potentially being used as a vaccine or adjuvant treatment for mesothelioma.” The study involved induced pluripotent stem cells (IPS), which are cells taken from the blood or skin and genetically reprogramed. This allows the cells to attack or prevent cancerous tumors when mixed with a generic immune-stimulating agent. Vaccine Shows Anti-Tumor Response The study tested mice infected separately with breast cancer, melanoma and mesothelioma cells. The anti-tumor response rate was similar in all three types of cancer. “This is significant for future cancer therapies, that we now have a surrogate cell that can provide the immune system with a large amount of cancer-related antigens,” Wu said. “Based on preliminary studies, the effectiveness of our vaccine is not limited to one cancer.” IPS cells typically are used in regenerative medicine, often to repair damage fro...

Malignant mesothelioma has become the latest deadly cancer linked directly to the rescue, recovery and cleanup efforts following the 9/11 terrorist attack on New York City in 2001. The long-running threat has come to fruition. Eighteen years after Manhattan was engulfed in the asbestos-laced, toxic cloud of dust — caused primarily by the World Trade Center destruction — the first death from pleural mesothelioma attributed to 9/11 has been recorded. Nick Ursta, 52, from the southwestern part of Pennsylvania, died after a year-long battle with the rare cancer. Ursta, a construction worker and fireman by trade, w...

ConclusionsA clear occupational excess of mesothelioma was not matched by a corresponding excess of asbestos-induced lung cancer. Confident interpretation of the excesses of cancers of the nasal cavities and small intestine is not possible, although occupational exposures received in this industry may well not be involved. An excess of skin cancer in transmission workers may be associated with outdoor working.

President Donald Trump on Monday signed legislation that will extend the September 11th Victim Compensation Fund until 2092. During the signing ceremony at the White House, Trump was surrounding by first responders, survivors and family members of several who died in the 2001 terrorist attack on the United States. The U.S. House of Representatives and the U.S Senate voted overwhelmingly last week to approve the legislation that will provide a lifetime of assistance for victims and their families. The extension will allow the fund, first established in 2001, to pay for past and future medical claims of those effected by the...

The U.S. Senate followed the House of Representatives on Tuesday and passed legislation that will extend the September 11 Victim Compensation Fund until 2092. The legislation will fund all current and future medical claims of those effected by the 9/11 terrorist attacks on the World Trade Center in New York City, the Pentagon in Washington, and United Flight 93, which crashed in Shanksville, Pennsylvania. The extension of funding will benefit victims who may develop mesothelioma linked to the more than 400 tons of asbestos that covered the 16-acre disaster zone after the twin towers fell. According to World Trade Center R...

The Senate gallery erupted in applause from politicians and first responders on Tuesday after a 97-2 vote to extend the September 11 Victim Compensation Fund until 2092. The reauthorization will fund all current and future medical claims of those effected by the 9/11 terrorist attacks on the World Trade Center in New York City, the Pentagon in Washington, and United Flight 93, which crashed in Shanksville, Pennsylvania. The extension will allow victims and their families to file claims through 2090, but they will be paid out through 2092. The extension of funding will benefit victims who may develop mesothelioma linked to ...

This study is an important step forward in highlighting C1q as a new prognostic candidate biomarker for a range of carcinomas. Methods Oncomine Database Analysis The expression levels of C1QA, C1QB, and C1QC genes in various carcinomas were analyzed using Oncomine (www.oncomine.org), a cancer microarray database and web-based data mining platform from genome-wide expression analyses (22, 23). We compared the differences in mRNA level between normal tissue and carcinoma. The mRNA expression levels in neoplastic tissues compared to the healthy tissues were obtained as the parameters of p-value 2, and gene ranking in the t...

Conclusions This review describes how leukocyte-heparanase can be a double-edged sword in tumor progression; it can enhance tumor immune surveillance and tumor cell clearance, but also promote tumor survival and growth. We also discuss the potential of using heparanase in leukocyte therapies against tumors, and the effects of heparanase inhibitors on tumor progression and immunity. We are just beginning to understand the influence of heparanase on a pro/anti-tumor immune response, and there are still many questions to answer. How do the pro/anti-tumorigenic effects of heparanase differ across different cancer types? Does...

This study aimed to explore whether a correlation exists between the incidence and mortality of cancers and normalized internet search volumes on the big data platform, Baidu. We also assessed whether the distribution of people who searched for specific types of cancer differed by gender. Finally, we determined whether there were regional disparities among people who searched the Web for cancer-related information. Methods: Standard Boolean operators were used to choose search terms for each type of cancer. Spearman’s correlation analysis was used to explore correlations among monthly search index values for each can...
