Nasopharyngeal cancer is a type of cancer that forms in the soft tissues of the nasopharynx.

There are different stages of nasopharyngeal cancer therefore once a person has been diagnosed with this disease it is necessary for tests to be performed to determine which stage that person is at. By determining that it will be easier to determine what stages of nasopharyngeal cancer treatment is needed to correct the problem or at least slow down the progression of the cancer.

Some of the symptoms that may indicate the presence of this cancer include sore throat, ringing or pain in the ears, difficulty hearing, talking or breathing, severe headaches and nose bleeds as well as the presence of lumps in the nose of lymph nodes on one side of the neck. Chinese or Asian ethnicity as well as exposure to Epstein-Bar virus may also be a factor in the onset of this type of cancer.

Each different stage of nasopharyngeal cancer may and often does include one or more of the standard treatments for this disease. For each stage of the disease there are also one or more stages of nasopharyngeal cancer treatment that are used for that stage.

Stage I

The most often used treatment option is radiation to the tumor and the lymph nodes located in the neck. In some cases this is also when clinical trial options are presented and used.

Stage II

Treatment sometimes includes both chemotherapy and radiation treatments. The radiation therapy used is generally the same as that that is used in stage I treatments.

Stage III

It may involve a treatment plan that utilizes all three standard methods of treatment being radiation, chemotherapy and surgery. The radiation therapy used is often the same as that used in stages I and II and may be followed with an operation to remove any lymph nodes that still contain cancer or return after radiation therapy or to remove tumors that are still present.

Stage IV

All methods are used starting with radiation and progressing to surgery. In some cases additional chemotherapy may be used to treat any cancer that may have spread to other locations. Clinical trials may also be introduced or re-presented at this time especially if all previous treatments have failed.

After all stages of nasopharyngeal treatment have been utilized and been determined ineffective or unsuccessful an individual may once again be given the option of participating in various clinical trials. If these are also unsuccessful it may be necessary to undergo some treatments such as radiation therapy or chemotherapy a second time.

The study was helmed by the associate professor cum vice-chairman, Department of Radiation Oncology, Dwight E. Heron, M.D., drew comparisons between the efficacy of single and several sessions SRS treatment in curbing the pain among patients. Dr. Heron believes that cancers could swiftly metastasize to the bone, and the spine is the location wherein the maximum pain is experienced. Dr. Heron stated that traditional radiation therapy is not often effectual in allaying bone pain arising from the cancer that has spread to the spine. In those patients that had earlier undergone radiation, hardly any choices of effectual treatment existed.

The study analysed the results of 228 patients that underwent treatment with the assistance of SRS at UPCI and Georgetown University Medical Center or GUMC. Patients who underwent treatment at the UPCI were administered single session of SRS treatment whereas patients that underwent treatment at GUMC were usually administered 3 sessions of SRS treatment.

Both the sections of the study adeptly proved that SRS was a totally safe and effectual line of treatment among patients that had cancer which had metastasized to the bones, and even was effective among those patients that had earlier undergone radiation therapy to the spinal region.

Dr. Heron added that an astonishing aspect that came to light was that those patients that underwent just a single treatment felt quicker pain respite; however those that underwent 3 treatments felt relief from pain for protracted time spans. In addition, patients that underwent 3 treatments felt lesser requirement for being re-treated and had increased rates of survival.

Conformal Radiotherapy (Computer-controlled Radical Radiotherapy)

A form of external radiotherapy wherein metal obstructers are introduced in the shaft of the X-rays that makes them more pliable and aid in matching more accurately to the contours of the prostate. Usually employed radiotherapy employs an additional ‘strewn’ beam, hence has lesser precision and could affect adjacently placed normal tissues.

Pros

The treatment has greater accuracy as compared to normal radiotherapy translating to adjoining healthy tissues being lesser affected.

Also this procedure has lesser side effects. IMRT or Intensity-modulated radiotherapy is the latest kind of conformal radiotherapy that could distribute varying dosages of radiation. This procedure is extensively obtainable.

Cons

Few of the cancer cells could be missed out during the treatment. However, those ailing from prostate cancer must ideally undergo medical hormone therapy subsequent to this procedure.

Medical Hormone Therapy

The objective of hormone therapy is the administration of the analogously effectual shots or regular intake pill version for removal of testosterone present in the body to starve the prostate cancer cells of the needed hormone leading to their shrivelling and death.

The jabs are chemical castration procedures that halt the manufacture of testosterone in the testes. The pill taken on a daily basis ingeniously hinders testosterone receptors in most parts of the body; hence it doesn’t affect other organs or tissues of the body. Though testosterone production is still on, its effect is majorly lowered.

Pros

When employed alongside radiotherapy, cancer cells present in the tumour could turn increasingly receptive to radiation therapy.

Cons

Though not able to treat the cancer, it does help to stave off the disease for few years. Men who undergone the treatment would experience development of female sexual characteristics like feminine distribution of hair and fat depositions, breast developing to some extent, along with turning impotent.

Also on commencement of the treatment, these men might undergo hot flushes and increased perspiration.

Prostate Cancer Treatment for Advanced Stages

Surgical Hormone Therapy

The operative procedure performed under the influence of general or local anesthesia for excising a single or both the testicles that take part in testosterone production with no need for hospital stay thereafter.

Pros

It is extremely beneficial at curbing cancer for variable spans of time in 9 among 10 men. A sole form of treatment that does not require the intake of pills or getting jabs.

Cons

This surgery could be distressing for some men as they would face impotency and depleted sex drive. Prostate cancer cells have a tendency to relapse.

Radioactive Therapy

Radioactive therapy generally conducted as an outpatient process, involves introducing radioactive substance throughout the body. The radioisotope Strontium 89 is intravenously injected in the arm which gets absorbed by the bones inflicted by the cancer and is aimed at annihilation of the secondary tumors present in the bone. This causes shrinkage of the larger tumors and the smaller-scaled ones could totally be eradicated.

An exhilarating novel means of radiation therapy employing radioisotope Radium 223 also known as Alpharadin, is presently under-trial phase globally, as well as at the Royal Marsden Hospital, London, that would safeguard the patients from few of the shortcomings of Strontium 89 that could have an effect on the bone marrow.

Pros

This is employed for assuaging the signs and lowering bone pain.

Cons

Strontium 89 could obliterate bone marrow; the treatment is a single-occasion-only type and a cycle could generally not be conducted again.

Taking this aspect into consideration, Radium 223 could evolve as a better choice as it could be conducted again.

Patients could find that their immune systems are immensely affected due to both of the treatments.

Chemotherapy

A treatment involving the obliteration of the cancer cells by either pills, shots or intravenously and is generally offered in the hospital in cycles interspersed with rest and recuperative time periods.

Pros

This treatment could aid in allaying signs alongside enhancing life quality.

Cons

Normal healthy cells that classically have swift growth like cells of the hair, gut or blood could be obliterated. There are several likely side effects like feeling nauseous, weariness, getting bruised, bleeding and loosing hair.

The procedure is quite pricey at five thousand pounds for a course, hence not recommended by all primary care trusts.

TURP

It is generally conducted for improving the flow of urine among patients ailing from benign prostate disease, however in case the cancer tumor is spreading at a swift rate leading to difficulties in urinating, then the doctor would suggest undergoing a TURP procedure that involves incising away the tissue present in the inflamed prostate gland that is exerting strain on the urethra.

Pros

One is conscious during the course of the surgery, hence there is lesser chances of side effects arising due to the general anesthesia.

Cons

It fails to treat the cancer and merely allays the distress. Hospitalization for some days subsequent to the treatment would be required. This could impede a man’s capability to ejaculate though men could continue having sex following the TURP procedure.

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.

Surgery

Surgery is the most prevalent form of treatment for Wilms’ tumor wherein the doctor might remove the cancerous growth employing one of the below stated procedures.

• Partial Nephrectomy – This procedure is conducted for removal of the cancer and a section of the kidney that is situated around it.  It usually is done in just rare cases when there is damage done to the other kidney or has previously been taken out.
• Simple Nephrectomy – This procedure involves the complete removal of the kidney. The other kidney would then take on the role of purifying the blood.
• Radical Nephrectomy – In this procedure there is total removal of kidney, adjoining tissues and some of the lymph nodes.

Chemotherapy

Chemotherapy is the usage of drugs administered in either pill form or intravenously for annihilating cancer cells. Chemotherapy is also known as systemic treatment as the drugs on entry into the bloodstream, pass through the body and can stamp out cancer cells all through the body .When chemotherapy is offered as a post-operative procedure then it is known as adjuvant therapy.

In case elevated doses of chemotherapy are employed for killing the cancer cells, then the high doses could mar the blood-producing tissue present in the bones or bone marrow. If elevated doses of chemotherapy are required for treating the cancer, then the bone marrow might be extracted from the bones prior to therapy and kept in the freezer till its need arises. Subsequent to chemotherapy, the bone marrow is intravenously reinstated. This is known as autologous bone marrow reinfusion.

Radiation Therapy

Radiation therapy makes use of X-rays or other forms of high-power rays for annihilating cancer cells and shrinking the tumors. Radiation done for treating Wilms’ tumor generally is given through a machine located outside the body, also known as radiation therapy. Radiation might either be employed prior to or following surgery and chemotherapy.

Some patients tend to develop a second, altered form of the cancer after several years due to the outcome of being treated with chemotherapy and radiation. On-going clinical trials are intended at ascertaining whether chemotherapy and radiation could be employed in lower doses.

Stage-Wise Treatment

Treatment offered is dependent on the stage of the tumor, cell type or histology and the child’s overall health condition and age. A standardised treatment is adopted on the basis of its efficacy in several patients in earlier studies or investigational. The doctor might suggest that the child partake in a clinical trial – a research project that involves new investigational treatments. Several patients do not seem to be cured using standard therapy and there may be undue number of side effects experienced with some of the standard treatments. Due to these reasons, clinical trials are intended for testing novel, better treatment alternatives.

Stage I – In case the tumor bears a ‘favourable’ cell type or the child is having anaplastic Wilms’ tumor, then surgery for removal of cancer would be the probable line of treatment followed by chemotherapy. Surgery and subsequently radiation therapy and chemotherapy would be the probable line of treatment in case the child is having either clear cell sarcoma of the kidney or rhabdoid tumor.

Stage II – In case the tumor bears a ‘favourable’ cell type, the treatment would mostly involve surgery for removal of cancer, after which chemotherapy would be given. In case the child is having an ‘unfavourable’ cell type like anaplasia, clear cell sarcoma or rhabdoid tumor of the kidney, then the treatment might include surgery that would be followed by radiation therapy and chemotherapy.

Stage III – The treatment would possibly be surgery after which radiation therapy and chemotherapy would be given. At times, it is not possible to remove the cancer via surgery as it is located in close proximity to vital organs or blood vessels or due to its overbearingly large size. In such situations, only biopsy is conducted following which chemotherapy might be suggested that may or may not include radiation. Subsequent to the cancer being minimised by treatment, surgery would be conducted, that would be followed by further chemotherapy and radiation therapy sessions.

Stage IV – The line of treatment would generally be surgery that would be followed by radiation therapy and chemotherapy. In case there has been cancer metastasis or the cancer spreading to the lungs, then further chemotherapy sessions might be given.

Stage V – If cancer has metastasized to both the lungs, generally it is unfeasible to remove both the kidneys. A portion of the cancer from both the kidneys and adjacent lymph nodes might be removed for checking the presence of cancer. Subsequent to surgery, chemotherapy is conducted for shrinking the tumor. Following reduction of the cancer, a second operative procedure might be conducted for removing major parts of the cancer, while attempting to leave as much part of the kidneys as possible. Surgery might be followed by additional chemotherapy and radiation therapy.

Persistent – In case the cancer has relapsed in the child, the treatment offered would depend on the treatment previously offered, the amount of time transpired following the last treatment, the type of the cancer cells and the location of its re-emergence. Based on these factors, treatment would comprise of surgery, radiation therapy and chemotherapy.

Clinical trials, investigative projects that involve patients, aid in assessing novel treatments, like chemotherapy drugs, novel blends of treatments and bone marrow reinfusion.

During the biopsy procedure, removal of the cells and tissues is done in order to be sent for microscopic analysis. The pathologist would analyse the sample to detect any symptoms of cancers. The experts namely, pathologist, radiation oncologist and surgeon would work in unison for charting out a plan on how to undertake the biopsy procedure. This is done to ensure that the biopsy incision would not affect the subsequent treatment involving surgical intervention for tumor removal and radiation therapy. When biopsy is conducted in the same location where the treatment would be carried out, it would be more beneficial for the patient.

The below stated tests might be conducted on the tissue sample that was removed during biopsy.

• Light and electron microscopy – A laboratory test wherein a regular and high-power microscope is used to scan the cells in the tissue sample taken during biopsy for any form of anomalous cell changes.
• Cytogenetic analysis – A laboratory test wherein the cells present in the tissue sample are microscopically analysed for spotting any abnormal changes in the chromosomes.
• Reverse-transcription polymerase chain reaction test or RT-PCR – A form of laboratory test procedure wherein cells present in the tissue sample are analysed by employing chemicals for observing certain genetic changes.
• Immunohistochemistry study – A laboratory test carried out to test for particular antigens by using substances like antibody, dye or radioisotope that are added to the tissue sample. This kind of study is employed for telling the variation between different cancerous types.

Factors affecting prognosis (probability of recovery) and Treatment choices

The prognosis or likelihood of recovery is dependent on particular factors prior to and subsequent to treatment.

Prior to treatment, prognosis is dependent on:

• The location in the body where the tumor originated.
• How large the tumor size is during diagnosis.
• If the tumor has metastasized or spread to other sites in the body.
• The age, sex and overall health status of the patient.
• If the tumor has lately been detected or is a relapse.

Following treatment, prognosis gets affected due to:

• If the tumor had been totally removed during surgical intervention.
• Has the cancer relapsed more than 2 years subsequent to the first treatment?

Treatment alternatives are dependent on:

• The location of the tumor in the body and how big the tumor size is.
• The age and overall health condition of the patient.
• How the treatment would affect the patient’s look and vital body functions.
• Has the cancer recently been detected or has it relapsed.

Decisions regarding opting for surgical intervention are dependent on how favourably the patient is responding to the preliminary line of treatment employing chemotherapy or radiation therapy.

The normally functioning white blood cells are powerful infection-combatants. However, among individuals affected with leukemia the irregular white blood cells have a tendency of accumulating, hindering normal white blood cell production and impeding the body’s capacity to combat infection.

Leukemia treatment is a multifarious approach wherein majority of the patients undergo chemotherapy, while others get treated with radiation therapy, BMT or bone marrow implant or biological therapy. In certain circumstances, surgical excision of the spleen would become part of the treatment approach.

The four key forms of leukemia include:

• AML or Acute Myeloid Leukemia – Noticed in both grown-ups and in childhood, this form of leukemia is at times known as ANLL or acute non-lymphocytic leukemia.
• ALL or Acute Lymphoblastic Leukemia – The widely prevalent form of leukemia noted in young children, though also affecting adulthood is inclusive of those in the elderly age bracket of 65 years and above.
• CML or Chronic Myeloid Leukemia – Though chiefly affecting adults, there are rarely few cases of children also observed with CML.
• CLL or Chronic Lymphocytic Leukemia – A condition that is mostly known to inflict older aged individuals past 55 years of age. Though at times, it is noted in the younger age bracket adults and rarest ever cited amongst children.

All leukemia forms can be treated with the right approach and majority of them have a potential of being cured.

Leukemia is categorized on the basis of the rate of proliferation, along with the kind of blood cells it is known to affect. The varied leukemia types widely differ according to their nature and gravity and are pigeonholed into either acute or chronic forms.

• Acute Leukemia – The more belligerent leukemia form that leads to acute symptoms and swiftly progressing to serious medical complications. A dearth of effectual treatment would lead to mortality within time spans of days to weeks.
• Chronic Leukemia – Progresses at a much slothful pace. Some cases do not need to be treated for months or years.

Leukemias additionally are categorized into myeloid or lymphoid forms on the basis of the kind of the white blood cell (WBC) that has been inflicted. Myeloid cells produce neutrophils – a crucial form of WBC that slaughters bacteria. Lymphoid cells produce lymphocytes that safeguard against bacterial germs inclusive of viruses.

Leukemia has been considered by many as a disease inflicting solely children, though approximately ten times as many grown-ups as children are detected with this form of cancer. Newly surfaced leukemia cases have mounted to roughly thirty thousand cases on an annual basis in the U.S.

Leukemia Signs and Symptoms:

AML or acute myeloid leukemia is a widespread form of acute leukemia that accounts to 80% of such cases, noted amongst adults that affects the primal WBC in the bone marrow. AML has 8 varied sub-categories that differ on the basis of treatment, diagnosis and the form of leukemia cell that is entailed. These comprise of:

• M0 – Undifferentiated Leukemia – Classified by the excessive production of extremely primal leukemia cells also called blasts, that are undeveloped to such an extent that at times it is tricky to decipher whether they are AML or ALL cells. This leukemia has a poor diagnosis and accounts for lesser than 5% of AML cases.
• M1 – Acute Myeloblastic Leukemia – This condition accounting for 15-20% of AML cases, is classified by the unwarranted production of very primal WBC or blasts. The bone marrow has in turn, few mature WBC’s.
• M2 – Acute Myeloblastic Leukemia with Maturation – This condition representing 20-30% of  AML cases is classified by the excess production of the primal WBC’s or blasts wherein the bone marrow comprises of full-grown WBC along with the presence of the blasts. A translocation among the 8th and the 21st chromosomes usually takes place and is suggestive of an improved diagnosis.
• M3 – Acute Promyelocytic Leukemia or APL – This leukemia form that can be related to acute bleeding, is classified by the occurrence of abnormal promyelocytes in the bone marrow and peripheral blood. A translocation among the 15th and 17th chromosomes commonly takes place and is suggestive of an enhanced diagnosis. This condition accounts for nearly 10-15% of AML cases.
• M4 -Acute Myelomonocytic Leukemia – This form of leukemia accounting for nearly 20-25% of AML cases is classified by the excessive production of monocytes and myelocytes – the WBC’s that combat contagious agents all over the body.
• M5 – Acute Monocytic Leukemia – The form of leukemia representing 5-10% of AML cases, is classified by the surfeit production of WBC’s, monocytes and monoblasts that are WBC’s which combat contagious agents all through the body.
• M6- Acute Erythroblastic Leukemia – This form of leukemia accounting for fewer than 5% of AML cases is classified by the excessive production of primal red blood cells. This leukemia has a poor diagnosis and mostly is noted to evolve from a condition known as myelodysplasia.
• M7 – Acute Megakaryoblastic Leukemia – Classified by the excess production of primal megakaryocytes that are the cells responsible for giving rise to platelets. This is an atypical form of AML that has an inadequate diagnosis.

Usually the onset of AML is sudden, i.e., in a period of days or weeks. It is not quite often for a patient to be sick for a couple of months. AML causes illness in persons mainly by hindering with the functioning of the normally occurring bone marrow. The offending leukemia cells reinstate and swarm out the normally functioning cells of the bone marrow, thus leading to the sapped blood cell counts. This inadequate number of red blood cells leads to a condition known as anemia that makes an individual feel fatigued and washed out. Dearth if platelets could make one more prone to blood loss and getting bruised, particularly in the skin, nose and gums.

Depleted levels of normal WBC’s raise the chances of infection. Though infections might be of any form, the classical symptoms comprise of:

• Fever.
• Experiencing a runny nose.
• Cough.
• Discomfort and pain in the chest region or breathing distress and shortened gasps.
• Pain experienced during urination
• Occasional diarrhea.

However, highly detrimental are the infections arising in the bloodstream known as sepsis, and pneumonia.
