The Oncology and Palliative Therapy
It is the totality of classic applications, related to cancer treatment, applied to patients who research treatment of the symptoms. In this sector are primarily interventions: surgery, radiotherapy, chemotherapy, hormonal therapy and immunology.
These actions are interconnected and iterate the disease, often interwoven and are repeated several times.
Palliative surgery :
Surgery plays an important role in the treatment of cancer and primary, it plays different functions: preventive, curative and palliative.
In his main role, aims to eliminate those changes that constitute a potential for malignant transformation. The curative surgery has a dual objective: remove and store. In this context, the surgeon is responsible for knowing how to define the boundary between the right to delete and what to keep and why conserving surgery and the healing is understood as synonymous. Palliative surgery is aimed at eliminating any situation that constitutes a threat to life, in emergencies, or to safeguard the quality of life in the terminal phase.
The quality of life of the patient should be an important goal for the surgeon and commitment. He also must take into account the psychological and emotional aspect of the patient. The patient hospitalized awaiting surgery, is located in a fragile psychological condition for the trauma they must endure and the fact that its existence depends entirely on the action of the surgeon and the outcome of the intervention. It is necessary to establish a relationship based on correct information, on good communication and above all on trust, this reduces the level of anxiety in the patient and helps to positively influence the postoperative course.
Although some might see Palliative Surgery as traumatic and aggressive, it is still seen as a way of deliverance from evil. The removal of the tumor is the first step in the process of care and healing is associated with the need to restore that balance the mental and physical health threatened. In fact, patients waiting for surgery, in general, they say: “I’m worried, but I can not wait to take away everything.” And again: “I hope to be on time.” In these expressions it is obvious anxiety of the patient but also his need to be considered for surgery, released by the tumor.
The radiation affects the cancer cells but also healthy ones, but it can repair much of the damage suffered and recover their functions. Radiation therapy is used to treat any localized tumor, including the Sebaceous skin cancer, tongue cancer, larynx cancer, brain or breast cancer and cervix cancer. It is also used for the treatment of leukemia and lymphomas. There are various types of radiation used in radiotherapy and various application techniques.
From the point of view of the results we can distinguish three different levels of radiation :-
- - Irradiation radical seeking a cure
- - Palliative irradiation: intended to obtain prolonged survival
- - Irradiation symptomatic intended to obtain the elimination of symptoms affecting the patient, but did not change the survival
Chemotherapy or more exactly the antiblastic therapy is aimed at achieving the primary or metastatic tumor lesion, to reduce the content and to decrease the aggressiveness of atypical circulating cells.
