ABOUT CANCER TREATMENT
ABOUT CANCER TREATMENT
There are many types of cancer treatment. The types of treatment
that you have will depend on the type of � cancer you have and
how advanced it is. Some people with cancer will have only one
treatment. But most people have a combination of treatments, such
as surgery with chemotherapy and/or radiation therapy. You may
also have immunotherapy, targeted therapy, or hormone therapy.
New strategies of cancer treatment are genetic therapy and clinical
trials. Genetic therapy identify destroyed or missing genes, which
cause cancer development and they are replacing them with normal
copies of genes. Patients are included in clinical trials and
are given novel drugs which are in examination phase when standard
treatment doesn 't give results.
Based on the fact that cancer is complex disease , the strategy
of treatment is chosen by a multidisciplinary team of doctors
(Oncologic Committee) which consist of: medical oncologist, oncologic
surgeon, gynaecologist, pathologist, and doctors of other specialities
when it is necessary.
SURGERY
Surgery is the oldest method of treatment and yet still the most common method of treatment.
Approximately 60% of patients with cancer undergo surgery. A surgical treatment is often combined with
chemotherapy and/or radiotherapy.
SYSTEMATIC THERAPY
Chemotherapy is a treatment using substances (cytostatic agent)
that travel through the bloodstream, reaching and affecting cells
all over the body. Besides many side effects that this treatment
can cause chemotherapy is the most efficient treatment upto this
day and age. There are 5 types of chemotherapy treatment:
 Induction treatment
of lymphoproliferative disease (Lymphoma, Hodgkin , Multiple myeloma,
Chronic lymphatic leukemia).
 Neoadjuvant and
conversional chemotherapy , biological therapy - using cytostatic
agents or /and monoclonal antibodies before surgical or radiation
treatment to reduce tumor growth or tumor downsizing.
 Adjuvant chemotherapy
-the use of cytostatic agents in order to destroy the rest of
tumor cells after the surgical treatment.
 Palliative chemotherapy
-therapy which has as a primary goal to facilitate symptoms caused
by cancer.
 Chemoprevention-therapy
of the future based on restoring the normal cell function.
RADIOTHERAPY
Radiation therapy uses high doses of high-energy radiation in order to destroy tumor cells.
Radiotherapy is used to treat the malignant and benign tumors either alone or in combination with other treatments (surgery, chemotherapy).
It is considered as the local mode of treatment because its effect depends on the ability of absorption of ionizing radiation by irradiated part of the body.
It is believed that about 50% of patients administered either as the main radiation therapy, or as an adjunctive therapy.
IMMUNOTHERAPY
A type of biological therapy that uses substances to stimulate or suppress the immune
system to help the body fight cancer, infection, and other diseases. It is also used to reduce the side-effects of chemotherapy .
STEM CELL THERAPY
ABOUT THERAPY
Transplantation of peripheral stem cells in oncologic patients
represents one of the treatment modalities. It is performed in
patients who underwent a complete treatment but still there is
a doubt that some malignant cells were left over in the organism,
or in patients with the recurrent disease, immediately after the
initial treatment. These patients, after separation of a stem
cell from blood and its freezing, are given large doses of cytostatics,
i.e. far larger doses of cytostatics anticipated by the standard
protocols. High doses of cytostatics lead to destruction of tumor
cells but unfortunately healthy blood cells as well. Patients's
stem cells, during such treatment, are returned to patients, which
creates new blood cells much faster and safer and does not allow
creation of, often, fatal complications.
INDICATIONS FOR THERAPY
 Patients with Hodgkin's
lymphoma with bad prognostic parameters and after fast recurrence
of the disease after initial treatment.
 Patients with other
forms of lymphoma, with the disease recurrence after a certain
time after finalization of the initial treatment.
 Patients diagnosed
with multiple myeloma.
 atients with refractive
testicular tumor.
 Patients with Jung
sarcoma.
 Patients with refractive
ovarian tumor.
 BPatients with
refractive breast tumor.
PROCESS OF THERAPY
Process of operation is very complex, complicated, and delicate.
It requires coordinated team work in accordance with the strictly
controlled procedures. Such process of operation requires certain
technical conditions and apparatuses. It is necessary to have
a modern and functional sterile block or facility, as well as
some storage facility for isolation apparatuses or collecting
of stem cells, which is performed by a specific apparatus. The
apparatus is similar to the one for dialysis. Furthermore, there
are also sets for separation and all other technical apparatuses,
which enable a safe and controlled collection of peripheral stem
cells. A collected stem cell is checked at special counters, which
is performed in order to be sure that we have collected a sufficient
number of specific cells. The equipment is very expensive and
complicated and it requires professional personnel.
Defrosting procedure is a simpler operation, but more complicated
for the patient because it requires patient's isolation and a
special intensive treatment. Up to that moment, the patient had
received high doses of cytostatics with a conscious intention
to destroy every possible survived malignant cell. Unfortunately,
it is good to stress out that this procedure also destroys healthy
stem hematopoietic cells. Besides returning of the patient's own
young stem cell, we also help such stem cell in its maturing and
growth with the most modern medicaments called growth factors.
The recovery period lasts from 7 to 14 days and until now, we
have performed such autologous transplantation in 10 patients
with lymphoma and multiple myeloma. The arrival of Prof. Jean-Peire
Lotz opens a new phase of high-dosage therapy and autologous transplantation
in solid tumors of testicles and breast.
CLINICAL TRIALS
ABOUT CLINICAL TRIALS
Clinical trials are interventions in clinical research which are designed to test the
efficacy and quality of new ways of treatment and diagnostic .Within clinical trials
new methods of surgical and systematic ( treatment by drugs ) methods. However the main
purpose of clinical trials are investigating the efficacy of novel drugs and implementing
them in every day practice.
TYPES OF CLINICAL TRIALS
There are three types of clinical trials known as Phase I, II and phase III.
Before intiating a clinical trial , all preclinical studies mutst be done on human
regarding the effect of novel drugs on tumor cells and cell cultures, and then
reproduce on live cells and measure the quality and the effect of treatment and side effects.
Clinical trials are conducted in a series of steps, called phases - each phase is designed to
answer a separate research question. Phase I: Researchers test a new drug or treatment in a
small group of people for the first time to evaluate its safety, determine a safe dosage range,
and identify side effects. Phase II: The drug or treatment is given to a larger group of people
to see if it is effective and to further evaluate its safety. Phase III: The drug or treatment is
given to large groups of people to confirm its effectiveness, monitor side effects, compare it to
commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase IV: Studies are done after the drug or treatment has been marketed to gather information on the drug's
effect in various populations and any side effects associated with long-term use. We can distinguish two
types of clinical studies based on wether they are conducted in one or many healthcare centers:
unicentric and multicentric .If there are several Healthcare centers included in clinical trials from
several countries then they are multinational clinical trials. Multinational trials give the best results
because they include most number of patients, gather most number of healthcare experts and because of this
reason they last shorter period of time, and the shortest period of time regarding including novel drugs in everyday practice.
THE ADVANTAGES AND DISADVANTAGES OF A PATIENT'S PARTICIPATION IN A CLINICAL STUDY
The main advantage of participation in a clinical study is the possibility to provide a patient with a new,
efficient medical drug ( as a monotherapy or combined therapy with standard drugs) which provide greater
benefit to a patient in comparison to the standard treatment. Furthermore, the supervision of patients who
participate in clinical researches are far more of a greater quality which results often in a better
attitude of patient toward treatment although it can be a significant burden for a patient.
On the other hand, the disadvantage of participating in a clinical study is the possibility of
development of the side effects which can be more severe than the effects of the standard treatment.
However, all clinical researches have the appropriate medical procedures for taking care of side effects.
In addition to this, it is possible that thoroughout the clinical trial, procedures such as taking
tumor tissue sample which doesn't help the concrete treatment may be taken, but these procedures in a
long course of time have a broader significance and long lasting impact on a development of improved
quality and cutting-edge treatments for future patients.
RIGHTS OF PATIENTS PARTICIPATING IN CLINICAL TRIALS
Before initiating a clinical study, patient must be given detailed and necessary
information in a written and oral form about the purpose of a clinical study, procedures
included in a treatment, description of the procedure or treatment, any potential
risks or benefits and possible side effects. Patient must give an informed consent prior to the enrollement in a clinical study,
in which is stated that a patient can refuse to participate in research at any given moment and that such an action will not
jeopardize or affect the standard care of treatment.
NURSE CARE
NURSE CARE IN ONCOLOGY
Health care in oncology is multidisciplinary and multiprofessional.
Health care is performed by a nurse, who, as a health care worker,
has multiple functions as: performer of the medical health care,
lecturer, counselor, researcher, and administrator.
These functions are performed by a nurse as a part of a medical
team, where she or he, as the doctor's associate, participates
in realization of their orders in medical, diagnostic, and therapeutic
procedures, and as a part of a nurse team, where she or he treats
the patient:
 as efficient as
possible through health care by implementation and evaluation
of oncologic health care procedures,
 provides expert
and professional help from the domain of oncologic health care
to other nurses and health workers, patients and their families;
organizes various kinds of professional meetings for improvement
of oncologic health care,
 helps in realization
of research projects by defining the problems from her/his domain
and their impact to oncologic care and treatment efficiency,
 helps the creation
of work organization which enables the efficient and optimal oncologic
care and development of professional nurse practice.
Continual medical education is performed at the following levels:
 Clinics and Departments
of health institutions,
 Affiliates of nurses,
 By participation
at the professional seminars in the country and abroad.
Health care vision:
 Nurses should
independently perform health care,
 Nurses have legally
regulated standards of minimal qualification,
 Nurses have standard
obligatory permanent education,
 Nurses have obligatory
testing of knowledge.
NURSE CARE AT THE ONCOLOGY INSTITUTE OF VOJVODINA
Nurse care is conducted at all clinics and institutes with the
aim of achieving the organized, systematic, individual, and continual
health care. The following health care is implemented: general,
semi-intensive, intensive, and special, depending on the patient's
needs. It is also possible to implement a palliative care in accordance
with the health politics of the Oncology Institute of Vojvodina
and the program of the competent institutions.
