Claims for `natural’ treatments are usually best taken with a healthy dose of scepticism – though some, like the aloe vera mentioned below, are almost self evident. Suggesting education reduces tobacco use and thus cancer levels seems more like a variation on a regular theme, while possible advances in using radiotherapy sounds all good news.
If you're a optimist, you're always either right, or disappointed. If you're a pessimist, you're always either right , or pleasantly surprised. Or maybe It seems like the devil is no longer trading musical talent for souls.
Aloe vera helps in keeping the skin hydrated
(Hyderabad} A recent study conducted by the Mangalore Institute of Oncology has proved that aloe vera-based cosmeceutical (cosmetic + pharmaceutical) creams are effective in reducing dermatitis, a skin rash which can be caused by therapeutic radiation for head and neck cancer patients.
The study was conducted on 60 patients with head and neck cancer who had developed scars on face and neck due to radiation, which is part of the treatment. Oncologist Dr Srinivas Chilukuri explains how it works: “Radiation treatment destroys the thermal glands beneath the skin which puts a stop to lubrication. Aloe vera’s lubricating property helps keep the skin hydrated and therefore, the skin starts healing.”
Aloe vera contains two hormones — Auxin and Gibberellins — which reduce skin inflammation. Dr Priyanka Nair, a dermatologist, said it is recommended for patients with chronic skin problems. “It is widely used as a home remedy for acne too. So it is no surprise that it is being recommended for scarring that occurs in cancer patients. It is an age-old remedy for marks,” said Dr Nair.
Improving people’s educational levels can lower cancer incidence: study
( GUWAHATI) - Linking education with lower incidence of cancer, a study by a team of researchers from the Dr Bhubaneswar Borooah Cancer Institute (BBCI) has shown that improving the present educational levels of the population stands to lower the burden of head and neck cancers (HNC) in the State.
The study demonstrated that an improvement in the educational level of patients lowered the relative proportion of patients addicted to tobacco consumption in any form, and thus it will lead to a theoretical decline in the proportion of HNC patients.
The term head and neck cancer covers a broad spectrum of anatomical sites of the mouth and throat. Globally, more than six lakh cases of head and neck cancers are diagnosed each year. In India and in Assam in particular, around 30 per cent of all cancers are HNC. Chewable tobacco and betel nut consumption is a customary habit among the different ethnic and socio-cultural groups in the North East, which accounts for the higher number of mouth cancer patients from the region.
“Imparting education on the ill effects and various hazards of tobacco consumption as part of school curriculum is a way forward to curb the menace of tobacco,” Dr Amal Chandra Kataki, Director of the BBCI, said.
Nanobiotix leverages physics to fight cancer
(Paris) Radiation kills cancer cells, but it also takes healthy cells with them. The problem puts radiation oncologists in a bind – higher doses could cure more patients but the collateral damage would put them at greater risk. Paris-based Nanobiotix may have a solution. The company is developing a technology called NanoXray: hafnium oxide nanoparticles (NBTXR3) that have the potential to magnify radiation doses without increasing damage to surrounding tissue.
“With radiation, you always have to cross healthy tissue, so you are limited in the dose you can deliver to the tumor,” said CEO Laurent Levy. “When the patient is getting their usual radiotherapy, these particles absorb nine-fold the energy that the cell can usually absorb, increasing cellular damage.”
The 50-nanometer particles (50 billionths of a meter) are injected directly into tumors and absorbed by cancer cells. From there, they multiply the radiation’s ability to liberate electrons from water molecules, generate free radicals and hopefully kill cancer cells.
Using physics to fight cancer appealed to Levy and colleagues because it’s indication agnostic. By magnifying the energy directed at cancer cells – without increasing the initial dose entering the body – NBTXR3 nanoparticles could maximize radiation against many cancers.
Early phase trial results in head and neck cancers have been encouraging. A study released at the recent American Society of Clinical Oncology (ASCO) meeting showed the treatment performed well in older patients with stage III and IV cancers. The nanoparticles were well-tolerated and patient results improved as nanoparticle doses were increased. Seven of the nine patients who received higher doses had complete responses.
“In such a patient, having a complete response means you can go home again,” said Levy. “You can start to eat again, to talk, to swallow.”
