  • Chemotherapy in the treatment of lung cancer

  • In patients with lung cancer, all three main methods of treatment of cancer patients are applied - surgical, radiation therapy of lung cancer,
    Chemotherapy and their various combinations. Tactics of treatment are established
    taking into account the histological structure and the degree of proliferation of the tumor, and
    also the age and functional status of the patient, opportunities and
    Clinic Installations.

    The main method of the treatment of lung cancer, providing persistent cure, is a timely operation. The history of the surgical treatment of lung cancer
    Hours more than 70 years when in 1933. American surgeon Grehem
    For the first time successfully performed a combined pneumonectomy.

    Despite the continuous improvement of the surgical method, the long-term results of lung cancer operations
    practically did not change around the world over the past 30 years and leave
    wish the best. Only 30-40% of radically operated lung cancer patients
    Survive check 5 years. Most of them have for
    2-3 years after the operation, the progression of the tumor process occurs
    With the damage to the intragenuous lymph nodes, the residue of the lung or
    remote organs. This is due to the peculiarities of the tumor biology,
    which at the apparent radicality of the operation is often already
    generalized disease.

    With the fact that the peculiarity of patients with an established diagnosis of lung cancer is an average of 20-25%, it is obvious that only a small proportion of patients has a chance for recovery. Late diagnosis of lung cancer
    determines the large percentage of palliative operations - when in connection with
    A large prevalence of the process is clearly unable to completely remove
    Tumor fabric. In such cases, surgery is often
    aims to eliminate threatening life complications - bleeding,
    Void, breakthrough tumor in breast cavity and t.D.



    Surgical method for the treatment of lung cancer

    Surgical treatment of patients with resectable (potentially removable) forms of lung cancer
    is the radical and most encouraging method giving real
    Prospects for full cure. After the first successful operations
    removal of lung back in the 30s of the twentieth century
    Improved, and the greatest successes achieved in the last two
    decades. To date, methodical and
    Technical aspects of operational interventions, identified indications for
    Lung cancer operations and
    The choice of its volume, studied the main questions of anesthesiology, intense
    therapy before and after surgery, prevention and treatment of postoperative
    Complications.

    With resectable (potentially removable) forms of non-cellular cell lung cancer (I - III stage) surgical treatment is a choice method. Under the refinement of the testimony to the operation with lung cancer
    these stages mean not so much determination of its expediency,
    how much is the establishment of the principal possibility of execution
    Surgical manual, which is achieved by assessing contraindications.
    Over the past two decades, contraindications are sharply narrowed
    Oncological and functional plan for surgical treatment
    Patients with lung cancer.

    Methods for the treatment of lung cancer
    In a significant number of patients with lung cancer
    There are contraindications for surgery
    Functional type. These include low compensatory capabilities
    Breathing and blood circulation, serious concomitant diseases
    (heart failure II and III degree; pronounced organic
    changes in the heart; Hypertension III ST.;
    Renal or liver failure, etc.). In the assessment
    Contraindications for lung cancer is always present subjective moment.

    On the unreasonable refusal of the operation of a patient with lung cancer
    The possibilities and practical experience of a medical institution also affect.
    Modern features of anesthesiology and intensive therapy allow
    Often to prevent violations of the function of organs and systems, especially when
    Adequate preoperative preparation. Refusal to operation with
    Oncological positions should also be seriously motivated. This
    The question must be addressed to collegially with the obligatory participation
    Thoracic surgeon having experience in surgical treatment of lung cancer.

    Standard operations for lung cancer
    are pneumonectomy (removal of all lung) and lobectomy (removal
    one share of the lung), as well as their options (expanded and
    Combined operation, lobectomy with circular resection
    Bronchi and others.). Bronchoplastic operations expand opportunities
    the surgical method and contribute to increasing rectaging to
    20% Among the first time identified patients with lung cancer
    of this localization. The volume and nature of the surgeon operation determines in
    depending on the localization and prevalence of the primary tumor, its
    Relationships to the surrounding organs and structures, state of intracient
    Lymph nodes.

    The greatest achievement of recent years is the ability to diagnose truly early forms of central lung cancer
    (Carcinoma in situ, microinvasive cancer) that can be cured
    not only the operational method, but also radiation (intra-freedom) or photodynamic therapy. With the last patient, lung cancer administered
    photosensitizer that accumulates predominantly in cancer
    cells, then with the help of bronchoscope, irradiation with rays
    Laser of a certain wavelength. Results justify application
    method - cure is achieved more than 90% of patients.

    Operations for lung cancer
    Many dangers are melted, which sometimes leads to intraoperative and / or
    Postoperative complications, as well as postoperative mortality
    (mortality). Improving operational equipment and
    anesthesiological manual, as well as a comprehensive
    intensive therapy before surgery and early after it
    contributed to a sharp reduction in frequency in recent years
    Postoperative complications.

    Postoperative mortality - the main indicator in the assessment of the immediate results of the surgical treatment of patients with lung cancer.
    In the early years, when surgical treatment began to carry out,
    Postoperative mortality was extremely high - up to 25%. IN
    The last two decades, progress in surgery led to her noticeable
    reduction - about 3-4%.

    With the lung stage cancer
    The surgical method allows to achieve 70-80% of patients with cure, II
    Stages, that is, in metastases in the nearest lymph nodes, - about
    40%, and at stage III, i.e., metastatic lesion more
    remote groups of lymph nodes - only 15-20%. Most cases
    death from recurrence and metastases of lung cancer
    account for the first 2-3 years after surgery. If patients are safe
    experiencing this critical period and in the control dynamic
    Surveillance does not detect the progression of the process, the forecast
    is favorable.

    Unfortunately, most patients are diagnosed with
    Large delay in the III-IV stages, many identify various
    Contraindications of the functional plan, and they are recognized by non-cultural.
    Elimination of errors in organizing the active identification of early forms
    Diseases at the stage of primary and refineering diagnostics of lung cancer,
    The use of the most efficient research methods as well
    Selection of rational healing tactics, taking into account modern achievements
    Clinical oncology, close dispensary observation after
    treatment will definitely increase the effectiveness of therapy of this formidable
    Diseases.



    Radiation therapy in the treatment of lung cancer

    The second effective method of treatment of lung cancer is radiation therapy. With non-cellular lung cancer
    Rauchery treatment is carried out on a radical program or with
    Palliative purpose. Radical radiation therapy provides for
    obtaining a long and resistant effect as a result of the death of all
    The cells of the primary tumor and intragenuary metastases.

    Lightweight Radiation Cancer Cancer
    is carried out using remote gamma facilities of betatrons and
    Linear accelerators generating brake and electronic radiation
    Energies from 4 to 35 MeV. There are many methodological options for ray therapy of lung cancer.
    Radical therapy on the radical program is possible in patients with local
    tumor process of the lung (I-II stage), which operation
    contraindicated or they refused. The cure of such patients
    achieved in 5-10% of observations. Radiant therapy for palliative
    The program is planned when lung cancer
    III Stages. In unadiscally operated patients and
    Cancer progression after surgery, radiation therapy is often combined with
    Polykhimotherapy.

    The immediate effect of light ray therapy for lung cancer
    Depends on the prevalence of the process, histological structure
    Tumors, values ​​of total focal dose. Half patients manage
    achieve full resorption of primary tumor and regional metastases,
    and in 40% - reduction of the intrabriety tumor process.



    Chemotherapy in the treatment of lung cancer

    Lung cancer chemotherapy over the past decades has become more efficient due to the synthesis of new drugs. With small lung cancer
    It is the main method of treatment and its effectiveness reaches
    60-80%, sometimes with complete resorption (resorption) of the tumor, which really prolongs
    life about 50% of patients. With early stages (i) of this histological
    Forms of lung cancer for the method of choice is surgical, but necessarily with postoperative multi-course (4-6) polychimotherapy.

    With non-cellular lung cancer
    Direct objective improvement (partial resorption (resorption) primary
    Tumors, regional and remote metastases) during chemotherapy
    It is achieved in 10-30% of patients, but complete resorption rarely occurs.
    It is carried out in contraindications to surgical and radiating treatment,
    as well as an additional treatment for operation
    local progressive process, when progressing a tumor after
    Surgical treatment.

    Polykhimotherapy is carried out for a long time (up to 6-8 courses)
    Preparations in various combinations: doxorubicin, prokarbazin,
    Cisplatin, Winnistine, etoposide, cyclophosphane, methotrexate,
    Bleomycin, Iphosfamide, Irinotecan, Taxother, Taxol, Vinorelbin,
    Gemcitabine and others. Intervals between chemotherapy courses - 3-4 weeks.

    Methods for the treatment of lung cancer
    The best results are achieved with a combination of chemotherapy with radiation therapy of lung cancer (chemo-processing), while it is possible simultaneous or consistent their use.

    Possible toxic reactions in chemotherapy include nausea,
    Vomiting, intestinal disorders, phlebitis, cystitis, dermatitis, allergic
    Reactions and other. The most frequent late complication is oppressed
    Bleelms. Therefore, blood tests are repeated at least 2 times a week and
    within two weeks after completion of chemotherapy.

    Improving the efficiency of surgical treatment of patients with non-cellular cellular cancer of the Easy Stage III is associated with the development of methods of combined treatment, which provides a combination of radical operation with radiotherapy of lung cancer
    and / or with medicinal antitumor treatment. Additional methods
    apply before or after surgery, during it, as well as in pre- and
    Postoperative period. Many of the combined treatment of lung cancer
    remain debated and unclear. However, it is obvious that at the III stage
    The results of combined treatment are better than one surgical.

    Often patients with plasticized lung cancer
    Enroll in hospital with severe respiratory failure on the background
    Obstructions (blockage) tumor trachea and large bronchi when speech
    There is primarily about emergency to eliminate threatening
    Life of respiratory and pulmonary heart failure. Designed
    Algorithm for the treatment of this contingent of patients with lung cancer using high-tech modern methods.

    Summarizing all the above, it can be concluded that the effective treatment of lung cancer is possible only when it has enough early detection until clinical symptoms appear. Active detection of lung cancer
    In the preclinical period remains a priority organizational
    Medical event that improves long-term treatment results.
    Performing at an early stage of organ-grumbling surgical or
    Endoscopic treatment not only gives the hope of a patient's cure,
    but also provides preservation of ability to work and the best
    Quality of life of patients.

    It remains to hope that on the one hand, coherent work as
    medical and social and state structures, and on the other -
    awareness and serious attitude to your health of our
    population in the conditions of the XXI century achievements will really increase
    The effectiveness of the struggle against this malicious disease.
