Stage 4 Squamous Cell Carcinoma Survival Rates

Stage 4 squamous cell carcinoma survival rates - The right squamous carcinoma of vocal tendons is the most well-known tumor in all larynx malignancies. Removed metastases are uncommon because of anatomical structures, lymphatic seepage, and poor blood supply. The frequency of distant metastases is also low due to the diagnosis of the tumor at the onset of the disease; Even a slight change in the surface of the vocal cords results in a change in sound.

In December 1999, a 38-year-old man was mentioned as a case of squamous carcinoma, affected by the vocal cord zone. After the initial work are included CT scan, X-ray chest, belly all U/S; The stage of the disease is defined as TI NO MO/Stage I. Stage 4 squamous cell carcinoma survival rates - Treatment design is determined by radical radiation therapy (cobalt). The total becomes productive. For this complaint he went to the breast doctor, who advised him an X-ray chest; Which shows some clearly defined turbidity with cavitation at the top of the right lung.

Based only on the results of radiography, the diagnosis of pulmonary tuberculosis was diagnosed and tuberculosis treatment started. Despite 2 months of treatment, he did not show a satisfactory answer. In January 2001, he visited the oncology clinic on the above-mentioned complaints. Stage 4 squamous cell carcinoma survival rates - Based on the history, clinical examination, radiographic results, and unsuccessful processing was performed KGB CT with an emergency, which demonstrated a significantly reduced density of soft tissues in the right lung, measuring 3.8 x 3.8 cm in the front Segment of the right upper lobe. The other two densities lie in the right rear basal segment of the right lung. There were evidence limfadenopati.

Taking into account the results of CT; The stomach U/S is performed to assess distant metastases. Primary site biopsy and pulmonary mass are performed. U/S belly and biopsy from the main site did not show signs of the disease, but the lung biopsy showed atypical cells that were strongly signalized for squamous carcinoma.

On the basis of all studies, the stage of the disease changed from phase I to phase IV. Therefore, the plan of the palliative system combined chemotherapy consists of Cisplatinum 75 mg/M 2 in days I and 5 Fluorouracil 750 mg/m2 from the days of 2-6, with each cycle repeated every 3-4 weeks. After at least two chemotherapy programs, responses to treatment will be evaluated clinically and radiologically to determine further management plans.

Proper vocal carcinoma is the most common cancer of the larynx. This rarely happens until the age of 40. Most of them are found in front of the second third, a small portion of the front trim and seldom in the back part. Their growth characteristics are determined by the unique anatomy of vocal ligaments. Dispersion of the lymphatic drainage of the wires in all areas other than the rear section makes the metastases of early lesions unlikely. The elastic layer in the larynx often tolerates cancer, which begins at the edges of the free strip and continues the underlying vocal and paraglottic muscles, which are the lower lateral pathways leading from the larynx through the cricothyroid chamber. When penetration into the underlying tissue can occur all degrees of motion disturbance, from the stiffness of the thin mucous membrane to the fixation of vocal ligaments. The ligament of the front Commission forms a bridge between the front ends of the actual vocal chords. This structure is found in the plates in the cartilage of the thyroid gland, and its presence usually prevents the penetration of cancer in the area, which often causes its upward transition to supraglottic and up to the membrane cricothyroid. From there, this defeat can escape from the larynx to the neck. On the off chance that tumor overcomes the ligamentous hindrance in the front compartment, the ligament infiltrates.

Glottic tumor is frequently distinguished at a beginning time of the sickness in light of the fact that even a slight change in the vibrating surface of the vocal tendons really brings about an adjustment in sound. The vast majority of them are unmistakable with routine examinations of the larynx, however a little part is hazy. Flexible endoscopy has expanded the ability to explore the larynx. Once the lesion has been detected, the assessment of the invasion of deep, volumetric and cartilage cells and the regional lymph node is increased by CT or MRI. The first effectively demonstrate the vertical expansion of the tumor, especially in the areas of subglottic and anterior Koma, while the latter offers the benefit of a multifaceted guttural visualization. The invasion of the larynx cartilage is crucial for the planning of care.

In the early swallow of cancer, radial or partial laryngectomy achieves excellent local control. With radiation, his voice is certainly better. After these procedures, the sound is usually normal or almost normal most of the time. On the other hand, all patients have hoarseness with different degrees after hemilaryngectomy or cordectomy. In most centers, most cases of larynx cancer are treated with radiation therapy, and part or total laryngectomy is used as a rescue operation in those who do not respond to radiation therapy. The actual result of survival for Ti lesions treated with radiation therapy showed 91% of local control. Localized control only with radiation in patients suitable for cordectomy is 97%. In the second case, the local control increased to 100% when the surgical rescue was added.

Carcinogenesis tumors postulated to require a number of genetic events. In the case of head and neck cancer, carcinogenic pathways are not established. However information there is an accumulation describing chromosome deletion, regrouping, especially on 3p, 9p and 17p chromosomes. Alternative retinoids receptors or receptors of epidermal growth factor were also described. Although there is a specific activation of an oncogene until now the usual sequence of events has not been explained. A clear genetic flux has been observed at all stages and in the places of the disease.

It should also be remembered that the second malignant disease is quite common in larynx cancer, from 15-21%. Sometimes it is difficult to distinguish between metastatic lesions and second malignancy with the following criteria, which may be useful to distinguish it: metastases usually occur early and most of the time of the year, while The second malignancy usually takes more time. Histology should be different from the primary lesion in the second malignancy compared to the metastatic disease, where it must be identical to the primary lesion.

Stage 4 squamous cell carcinoma survival rates - The injuries of masturbation are typically multiplied contrasted with the second danger, which is normally single. In our case, the lung lesion appears earlier in 8 months and there are many lessons. Histology lesions do not indicate the presence of bronchial. Therefore, given the foregoing, we assume that in our case, lung lesions are usually more metastasize than the second malignant and thus reported.
