Treatment options in stage III non-small cell lung cancer.

Lung cancer is responsible for over 1 million deaths annually, worldwide. The disease becomes symptomatic in advanced stages, so the diagnosis is delayed and 90% of cases cannot benefit from a curative treatment. In NSCLC surgical resection represents the best option for long term survival in resectable stage III and in clinical stage I/II. Patients with stage IIIB or IV usually receive chemotherapy or palliative treatment. For patients with no driver mutation detected platinum based combination chemotherapy is the first choice. Definitive radiotherapy is considered an lternative for patients who are not candidates for combined modality treatment. When a stage IV cancer is diagnosed based on an isolated metastasis, the patient's benefit from the removal of the etastasis and of the primary tumor if it is resectable. The prognosis in NSLC is mainly influenced by the TNM stage at diagnosis. The rate of survival decreases in opposing correlation with the stage of the cancer. Poor performance status, reduced lung capacity, weight loss, vascular invasion are indicators for a poor prognosis

Benefits of a 7-week outpatient pulmonary rehabilitation program in COPD patients.

BACKGROUND: Respiratory rehabilitation programs (RR) are essential tools in the management of COPD. AIM: We present the results of a 7-week outpatient rehabilitation program in terms of dyspnea, exercise tolerance and quality of life. MATERIAL AND METHOD: The following parameters were evaluated before and after RR: dyspnea (mMRC scale), pulmonary function (FEVI, RV- residual volume), exercise tolerance (6MWT- 6 minutes walk test, CPET - cardiopulmonary exercise test), quality of life (SGROQ questionnaire). The RR program was outpatient, hospital based (7 weeks, 3 sessions/ week) and included: exercise training, therapeutic education, and psychological support. RESULTS: 25 patients, COPD stage II-IV GOLD (mean FEVI 44.5 +/-13% predicted), mean age 60.4 +/-12 years, 7 females, average BMI 27.14+/-4 kg/m2, average RV residual volume 221.55+/-86% predicted. Mean 6MWTdistance: 407.48 +/- 84 m and mean maximum power (Pmax) obtained on CPET: 75.67+/-30 Watts. All patients were symptomatic with significant dyspnea (3.06+/-0.7 on mMRC scale) and showed a significant impairment of quality of life: SGRO score 46.23+/- 14. At the end of RR program: dyspnea decreased with 0.67points on mMRC scale (p = 0.000), 6MWT distance increased with 58.5 m (p = 0.0071), Pmax obtained during CPET increased with 11.2 W, without reaching statistical significance (p> 0.05). SGRO score decreased by 5.59 points (p = 0.02). There were no significant improvements in FEV1 and RV values (p> 0.05). CONCLUSION: In our COPD patients, the 7 week outpatient rehabilitation program was effective, leading to improvement ofsymptoms, exercise tolerance and quality of life.

The contribution of exercise testing in the prescription and outcome evaluation of exercise training in pulmonary rehabilitation.

Pulmonary rehabilitation is a comprehensive therapeutic intervention with proven efficacy in relieving symptoms and increasing exercise tolerance in patients with chronic respiratory diseases.One of the main components of a pulmonary rehabilitation program is lower limbs exercise training. There are several ways of establishing the optimal intensity of the exercise training, using the target heart rate, symptom scores, walking tests and laboratory exercise tests with or without ventilation or gas exchange measurements. Each of these methods has advantages and disadvantages.The gold standard in exercise capacity evaluation is cardiopulmonary exercise testing (CPET) which brings a high level of objectivity in exercise tolerance evaluation and provides information on mechanisms responsible for its decline; this allows a better training prescription and a correct evaluation of rehabilitation outcomes.

[Functional evaluation before lung resection for cancer--international recommendations]. / Evaluarea functionala a pacientilor înaintea rezectiei pulmonare pentru neoplasm-- recomandari internationale.

Complications and disability after radical therapy for lung cancer can be predicted by preoperative functional evaluation. Functional tests and threshold values of the parameters have been described and included in a well-validated algorithm, ensuring functional reserve evaluation of candidates for pulmonary resection. There are no defined tests or cut-off values to provide predictions of complications after chemo-radiotherapy or limited pulmonary resections.
