Researchers aimed at ascertaining whether administering elevated radiation dosages using proton beam therapy could lead to early detrimental side effects to the urinary function within the GU or genitourinary system and the rectal functioning within the GI or gastrointestinal system.

Proton therapy is quickly garnering immense popularity as a potent prostate cancer treatment, but it is fuzzy as to whether the long-standing results of proton therapy would surpass those attained by other treatment methods. These procedures were intended to create yardstick outcomes with proton therapy offered at comparatively elevated every day dosages.

Nancy Mendenhall, M.D., the author of the study and the medical director from the University Of Florida Proton Therapy Institute, Jacksonville, Fla., stated that presently they have found that early tolerance of proton therapy has appeared to be promising with a minimal rate of urinary and rectal noxious side effects. She mentioned that the study proves that proton beam therapy was a viable choice among prostate cancer patients with diminutive chances of any side effects to the urinary and rectal functioning.

Proton beam therapy is a kind of external beam radiation therapy that employs protons instead of photons (X-ray beams) for treating particular forms of cancer and other ailments. The physical features of proton beam therapy allow easier delivery of radiation to the tumor with lesser-intensity radiation being passed to the adjoining normal tissues.

In the course of an external beam radiation therapy, a radiation shaft (X-ray or protons) is passed via the skin reaching the malignant growth and it’s nearest adjoining area for destroying the major tumor growth and any of the adjacent cancer cells.

During the time spans from August 2006 till October 2007, there were 212 prostate cancer entrants for 1 of the 3 forthcoming trials for receiving proton therapy. Those patients in the high-risk category were also given the chemotherapy drug – docetaxol, subsequent to which hormone therapy was offered to them.

The researchers had follow-up session with these patients subsequent to treatment for no less than a year’s time to keep tabs on the scores of genitourinary and gastrointestinal toxicity employing both the IPSS (International Prostate Symptom Scores)  and CTCAE, v.3 (Common Toxicity Criteria for Adverse Events) in case of each of the patients that underwent the trial.

The outcome revealed that there was negligible early genitourinary and gastrointestinal toxicity on prospective trials of proton therapy. Lesser than 1% of patients faced Grade 3 gastrointestinal toxicities with the commonly observed side effects being least amount of rectal bleeding that was linked to the section of the rectal wall that received the series of radiation dosages.

The frequency and the extent of severity of the rectal signs were additionally affected by colonoscopic intercessions subsequent to treatment.

Dr. Mendenhall appeared quite optimistic with the outcome of their study and further added that though there were a number of toxicities that might be occurring later on, the researchers were highly delighted with the early toxicity scores as compared to the other treatment choices. Additional follow-up would be needed in such patients for ensuring that these men didn’t experience any kind of side effects that might surface years subsequent to the treatment.

Physical Examination

During the course of the physical examination, the body is checked for overall health condition inclusive of looking for signs of any ailment like lumps or any dubious appearance. The patient’s history is probed to identify health habits, any previous asbestos exposure, past infirmity and treatments undergone.

Chest X-ray

An x-ray is an energy shaft that could pass via the body and onto film, capturing images of inner organs and bones of the body. The chest x-ray is performed for obtaining x-rays of the organs and bones within the chest region.

Complete Blood Count or CBC

A procedure involving the withdrawal of a blood sample to check for the below stated:

• The red blood cells (RBC), white blood cells (WBC) and platelets count.
• The haemoglobin (the oxygen-carrying protein) content in the red blood cells.
• The part of the blood sample that constitute the red blood cells.

Sedimentation Rate

During the procedure the blood sample drawn is evaluated for the settling rate of the red blood cells to the base of the test tube.

Biopsy

The extraction of cells or tissues is done from the pleura or peritoneum to be sent for microscopic analysis for spotting malignant growth. Procedures employed for collection of tissue or cell samples involve the following:

Fine-needle aspiration (FNA) biopsy of the lung

With the guidance offered by the imaging procedure, through a small incision done on the skin, a fine needle is passed for drawing out tissue or fluid samples from dubious or abnormal tissues or fluid accumulation in the lung.

Thoracoscopy

Through a small slit made in the inter-rib area, a thoracoscope – a fine, tubular illuminated device fixed with a viewing lens is inserted within the chest.

Peritoneoscopy

A tiny opening made on the abdominal wall is made thorough which a slender, tube-alike, light and lens fitted device is passed into the abdomen.

Laparotomy

Through a small cut made in the abdominal wall, the interiors of the abdomen are examined for any presence of disease.

Thoracotomy

An inter-rib slit is done for observing the chest interiors for presence of ailment.

Bronchoscopy

In this procedure the interiors of the trachea and the large air passages in the lung are examined for irregular growths. With the assistance of a bronchoscope (a slender, tubular, illuminated and lens-attached device) passed nasally or orally into the trachea and lungs for viewing and removal of tissue samples to be analysed microscopically for cancer signs.

Cytologic examination

In case of mesothelioma, the fluid build-up in the region around the lungs or abdominal region is drawn to be forwarded to the pathologist for microscopic analysis for checking the cells present in the fluid.

The path breaking contraption functions by instantaneously spotting the presence of malignant cells in so-dubbed surgical smoke, the gas produced during cutting or cauterising tissue during surgery.

The prompt response would mean that the doctors could be certain they have eradicated all malignant growth that could be skulking in the body.

Surgery is the crucial part of majority of the cancer treatments. However, it could be quite tricky for surgeons to be sure that they have taken out the entire tumour.

Currently, scans are done of the tumour to determine ahead of time, what they would require removal. In majority of the situations, the surgeons incise few centimetres more of the adjacent tissues in order to be on the safer side.

However, the procedure is still quite rudimentary and the risk of remnant cancerous cells within the body is quite high.

The newest innovation, by researchers from the Justus-Liebig University, Giessen, Germany, could be a potent way out. The scientists have employed an electroscalpel – an appliance that emits waste vapours during incision through the tissue – and connected to an apparatus known as a mass spectrometer – a kind of equipment normally employed in the lab for chemical investigation. It could detect thousands of varied kinds of molecules by examining their mass and electrical charge.

It is common knowledge that malignant tissues have a diverse chemical outline in comparison to normal tissues. However, till lately, there has been no available means of examining it during the time of surgery.

The German group of scientists have detected that the suction of surgical fumes into the mass spectrometer could provide instantaneous response as to whether the tissue being incised is malignant or not.

They evolved a means of rendering this into a body map that appears on to a screen in the operating room.

Professor Zoltan Takats, who is helming the research, states that there is no direct data available of the tumor presence during the course of the cancer surgery. Hence, they intend to furnish the surgeons with a tool that would help them instantly test any kind of dubious presence during the course of the surgery itself.

• A potent new-fangled treatment that employs light is presently undergoing test in the investigational phase at the University College London for the effectual treatment of head, neck and breast cancers.

The innovatory novel therapy dubbed PCI (photochemical internalisation) could firstly be available to British patients.

During the treatment, a chemical known as photosensitiser is firstly injected into the cancer cells. This chemical is known to elicit a strong, violent reaction when a laser ray is directed towards it.

During the next step of the procedure, the cancer-combatant drug known as bleomycin is injected. Bleomycin is a drug that has previously been employed, however, alike several cancer treatments, it could mar normal tissues alongside cancerous tissues and lead to disagreeable side-effects, like nausea and weariness.

With the novel therapy, as soon as the drug molecules are placed in position close to the cancer cells, a laser beam is directed onto the body for activating the photosensitive chemical.

This shatters the cancer cells internally and facilitates the easy seepage of bleomycin that aids in destroying the cancer cells more effectually.
