Brachytherapy

Brachytherapy also known as seed implant therapy or interstitial radiation therapy is a least invasive procedure involving implantation of small (sized like a rice grain) lasting radioactive seeds within the prostate where they help in irradiating cancer from within the gland. Radioactive seeds on implantation are so small-sized that they are not sensed by the patient. Based on conditions, radioactive palladium or iodine would be employed.

Prior to implantation of the seeds, the patient is anaesthetized. Insertion of needles holding the seeds are then done via the perineum skin (lying between scrotal and anal area) employing ultrasound supervision. These seeds stay in the prostate, where they emit contained radiation for some months to annihilate the prostate cancer.

Seed implantation is an effectual treatment for males having prostate cancer limited to a small area. No operative incising is needed during the procedure and it provides briefer recuperation periods. It could be performed on an outpatient basis with majority of the patients leaving the very day they received the treatment.

Cryotherapy

Cryotherapy eradicates the disease by a process of freeze-killing cancer cells in the prostate gland. After a patient has been anaesthetized, a surgeon would insert needles within the prostate gland via the perineum skin. These needles create extremely low temperatures and help in freeze-obliterating the complete prostate, inclusive of any malignant tissue in it.

Cryotherapy employs really fine needles for producing ice orbs of below-zero temperatures. Ultrasound helps the surgeon in accurately controlling the volume and form of the ice orbs and monitoring the freezing.

Cryotherapy is a choice for those prostate cancer patients intending on avoiding major surgical intervention or not keen on taking chances by adopting watchful wait policy. This procedure could help in treating those patients in the intermediary and elevated risk category along with those who have found no benefits from past radiation treatments.

Cryotherapy could be re-performed in case needed or employed as a secondary treatment in case other key treatments are unsuccessful.
The key risk linked with this procedure is impotence as for ensuring total annihilation of cancerous cells, the objective is freeze-killing the tissues past the prostate that could affect nerve clusters linked with erection located near the prostate.

In majority of the cases, the procedure last lesser than 2 hours and least discomforting sensation and pain felt with mobility reinstated the same day.
Side effects of this procedure could be moderate-ranging pelvic discomfort, bloody urine, mild-ranging urinary exigency, swelling in scrotum. All these generally subside in some weeks and recovery to normally functioning bowel and bladder is possible.

EBRT Procedure

EBRT or external beam radiation therapy employs a machine targeting a ray of ionizing irradiation on the malignant tissues. It appears alike undergoing X-rays, however taking more time. The procedure harms heritable matter in all cells that divide within the targeted lesions thus averting cell growth and their eventual death.

EBRT performed on an outpatient basis is a choice for those wherein cancer is restricted to prostate gland.

Hormonal Deprivation Therapy

Male hormone testosterone is the key stimulus for all prostate cells. A few forms of prostate cancer cells in fact need elevated dosages of this hormone and on its elimination via hormonal therapy could provisionally slacken prostate cancer cells from growing however not stopping them.

Hormonal deprivation therapy is of three key types:

• Operative Castration
  This non-reversible method involves removal of testicles via procedure known as orchiectomy. A fairly simple method performed under influence of local anaesthesia and patient could be given discharge from hospital the same day of surgery though in a number of situations, the patient would need to be hospitalized.

• LHRH Therapy
  It involves administration of luteinizing hormone-releasing hormone or LHRH generally taken via oral course and help in preventing testicles from manufacturing male hormone. This treatment spares the testicles and functions analogous to operative castration.

• Combined androgen blockage
  It comprises oral administration of female hormone estrogen for halting testosterone production.

A plummet in hormone level could have an effect on cancerous cells even among those who have metastasized past their initial site. This treatment could help in controlling prostate cancer for many years. Despite having undergone surgical castration, adrenal glands would help in compensating for testicles being removed by manufacturing greater levels of male hormone. Despite testicular removal, a man would require taking medicines for blocking flow of testosterone.

Side effects of hormonal therapy comprise of: turning impotent, lost libido, hot flashes, weight increase, weariness, lowered brain functioning and lost muscular mass.

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.

Cancer treatment is either local or systematic therapy.

• Local Therapy –Local therapies like surgery and radiation therapies help in removal and eradication of cancer that might be present in or in close proximity to the stomach. When the stomach cancer metastasizes or has proliferated to other areas of the body, then in such cases local therapy might be used for controlling the disease in those particular areas.
• Systemic Therapy – Systemic therapy like chemotherapy employ the use of drugs that enter the bloodstream and annihilate or curb the disease all through the body.

As cancer treatments mostly cause harm to the healthy tissues and cells, hence it is common to experience side effects that depend chiefly on the kind and the degree of treatment. Side effects might vary for each individual and from one treatment sitting to the other.

Prior to commencing on the treatment, the health care team would elucidate to the patient about the probable side effects and propose means to assist in managing them.

Surgery

Surgery is the widely prevalent form of stomach cancer treatment that is dependent on the extent of the disease. There are two key types of stomach cancer surgery available:

• Partial or subtotal gastrectomy – This involves removal of a section of the stomach that has the presence of the malignant form. The surgeon would additionally eliminate certain sections of the esophagus and section of the small intestine. Lymph nodes and tissues that lie in the adjacent areas might also be taken out.
• Total gastrectomy – The doctor totally removes the stomach, the adjacent lymph nodes, sections of the esophagus and small intestine, and other types of tissues located close to the tumor. The spleen might additionally be eliminated subsequent to which the esophagus is directly attached to the small intestine. By using the tissues from the intestine, the surgeon would make a new stomach.

There are bound to be concerns regarding eating following stomach cancer surgery. During the course of the surgery, a feeding tube is inserted within the small intestine that assists in providing adequate nutrition while the patient is recuperating.

The healing period would vary in each case. One might feel discomfort during the initial few days. Medications could assist in allaying the pain. Several people that have undergone stomach surgery might experience weariness or weakness for a while. Constipation or diarrhea is also reported following surgery. Such symptoms generally could be managed by varying the diet and medications. Any symptoms of bleeding, infection or other kinds of problems could also need to be treated.

Chemotherapy

This procedure involves the intravenous administration of anticancer drugs that after gaining entry within the bloodstream aid in killing the cancer cells and could majorly affect cancerous growth all through the body. However, certain drugs might be given orally.

Several persons undergo chemotherapy following surgery while in other situations radiation therapy might be administered alongside chemotherapy. The chemotherapy sessions might be given at a clinic in a hospital, the doctor’s office or at the patient’s residence. There might be others requiring hospitalization during treatment.

The side effects arising due to chemotherapy are dependent chiefly on the particular drugs and the dosage. The drugs are known to combat cancer cells and other cells that quickly proliferate.

• Blood cells – Such cells assist in combating infection, assist in blood clotting and transporting oxygen to all areas of the body. When blood cells get affected due to the drugs, the patient is more prone to infections, bruising or easy bleeding and would constantly feel weakness and fatigue.
• Hair root cells – Hair loss could occur due to chemotherapy drugs. Though there would be re-growth, the colour and texture might feel quite different.
• Cells lining the digestive tract – Chemotherapy could lead to loss in appetite, feeling nauseous, vomiting, diarrhoea or sores forming in the mouth and lip.

The drugs administered for treating stomach cancer might additionally lead to skin rashes or itchiness.

Radiation Therapy (Radiotherapy)

This procedure employs high-power beams for eradicating the cancer cells. This is a target-specific kind of treatment done using a mammoth machine that emits the radiation. The duration of the treatment is generally five days per week spanning for several weeks.

Side effects are dependent on the dosage of radiation and what part of the body is undergoing the treatment. When radiation therapy is carried out in the abdominal region, it could lead to pain and discomfort in the stomach or intestinal region. One might feel nauseous and get diarrhea. The area of the skin that is being treated might redden, dry up and might show tenderness.

One is prone to experience significant weariness during the course of the radiation therapy, particularly so in the later part of the weeks of the treatment. Though taking adequate rest is crucial, however doctors normally suggest that patients must attempt to continue staying as energetic as they possibly could.

Though the side effects arising due to radiation therapy could be agonising, the doctor would generally treat or try to curb them. Side effects normally subside after the treatment concludes.
