RESUMO

PURPOSE: The purpose of this study was to determine survival, local and distant control, toxicity, and prognostic factors in patients with stage III non-small cell lung cancer (NSCLC) treated with concurrent chemoradiation therapy (CCRT). METHODS AND MATERIALS: Consecutive patients with stage IIIA and IIIB NSCLC (N = 154) staged with 18F-fluorodeoxyglucose positron emission tomography/computed tomography were retrospectively selected (2005-2015). CCRT consisted of daily low-dose cisplatin (6 mg/m2) combined with 24 fractions of 2.75 Gy to a total dose of 66 Gy. RESULTS: During a median follow-up period of 22 months (range, 1-92 months) the median overall survival was 36 months. The 1-, 2-, 3-, and 5-year survival rates were 79% (95% confidence interval [CI], 73%-86%), 61% (95% CI, 54%-70%), 52% (95% CI, 43%-60%), and 40% (95% CI, 31%-51%), respectively. The local relapse-free survival at 5 years was 55% (95% CI, 44%-69%). Metastasis-free survival at 5 years was 53% (95% CI, 44%-65%). The incidence of severe gastrointestinal disorders (grade 3-5) was 11%, among which grade 3 radiation esophagitis was 8.4%. The incidence of severe respiratory, thoracic, and mediastinal disorders (grade 3-5) was 8.4%, among which grade 3 radiation pneumonitis was 1.3%. Predictors of overall survival were lymph node gross tumor volume (GTV) (hazard ratio [HR], 1.007; 95% CI, 1.000-1.012) and sex (HR, 0.500; 95% CI, 0.320-0.870) in favor of women. Although lymph node GTV was a predictor of treatment toxicity (HR, 1.010; 95% CI, 1.000-1.013), tumor GTV was the predictor for distant metastasis during follow-up (HR, 1.002; 95% CI, 1.001-1.003). CONCLUSIONS: CCRT with daily low-dose cisplatin for locally advanced stage III NSCLC resulted in promising overall survival (3-year survival rate of 52% and 5-year survival rate of 40%) with low toxicity. Lymph node GTV, tumor GTV, and sex were predictors of overall survival, treatment toxicity, and distant metastasis.

RESUMO

BACKGROUND AND PURPOSE: In the treatment of patients with tumours of the sulcus superior (SST), achieving local control is essential because residual or recurrent disease is associated with severe locoregional problems. This study evaluates the efficacy of concurrent daily low-dose cisplatin (6 mg/m(2)) and high-dose radiotherapy (66 Gy) followed by surgical resection in selected patients. MATERIAL AND METHODS: Clinical charts, imaging and pathology reports were retrospectively reviewed. Survival was analysed using the Kaplan-Meier method. RESULTS: Forty-nine patients with stage II/III SST were treated with concurrent high-dose radiotherapy and low-dose chemotherapy (CRT). Mean follow-up was 49 months (range 2-152). Nineteen patients underwent additional resection after CRT. In 53% a pathological complete response (pCR) was observed (10/19 pts). Acute severe toxicity occurred in 49% (9/19 pts). Late severe toxicity occurred in 3 patients. The 2- and 5-year overall survival was 74% and 33%, respectively. Local tumour control was 100%. Thirty patients received CRT only. Acute severe toxicity occurred in 23% (7/30 pts). Treatment-related mortality was 2%. The 2- and 5-year overall survival was 31% and 18%, respectively. Locoregional disease-free survival was 48% at 5 years. CONCLUSIONS: Concurrent high-dose (66 Gy) radiotherapy and daily low-dose cisplatin was associated with a high pCR rate. Excellent local control was achieved after additional resection in selected patients. However, the occurrence of severe toxicity in long-term survivors after concurrent chemoradiation followed by surgery must be considered.

RESUMO

INTRODUCTION: Esophageal cancer is an aggressive disease with a strong tendency to infiltrate into surrounding structures. The aim of the present study is to determine the additional value of bronchoscopy for detecting invasion of the tracheobronchial tree after endoscopic ultrasonography (EUS) in the preoperative assessment of patients with esophageal cancer at or above the carina. MATERIALS AND METHODS: Between January 1997 and December 2006, 104 patients were analyzed for histologically proven esophageal cancer at or above the carina. All patients underwent both EUS and bronchoscopy (with biopsy on indication) in the preoperative assessment of local resectability. RESULTS AND DISCUSSION: After extensive diagnostic workup, 58 of 104 patients (56%) were eligible for potentially curative esophagectomy; nine of these 58 patients (9/58, 15%) appeared to be incurable peroperatively because of ingrowth in the tracheobronchial tree (five patients), ingrowth in other vital structures (two patients) or distant metastases (two patients). Of the 46 non-operable patients, local irresectability (T-stage 4) was identified in 26 patients (26/46, 57%) due to invasion of vital structures on EUS: invasion of the aorta in six patients, invasion of the lung in 11 patients; in 12 patients invasion of the tracheobronchial tree was described, which was confirmed by bronchoscopy in only five patients. No patients with T4 were identified by bronchoscopy alone. CONCLUSION: For patients with esophageal tumors at or above the carina, no additional value of bronchoscopy (with biopsy on indication) to exclude invasion of the tracheobronchial tree was seen after EUS in a specialized centre. Although based on relatively small numbers, we conclude that bronchoscopy is not indicated if no invasion of the airways is identified on EUS.

RESUMO

The progression-free survival (PFS) of cyclophosphamide/doxorubicin/etoposide (CDE) and carboplatin/paclitaxel (CP) was compared in chemonaive patients with extensive disease small-cell lung cancer (ED-SCLC). A total of 203 patients were randomised to three-weekly CDE (n=102) or CP (n=101) for five cycles. Tumour response rates in CDE and CP were 60% and 61%. PFS of CP was 5.2 months, PFS of CDE 4.9 months (p=0.60). The major difference in toxicity between CDE and CP was grade 4 leukocytopaenia in 64% and 9% of the patients (p<0.0001), leading to febrile neutropaenia in 30% and 4% of the patients (p<0.0001), respectively. This was the reason for differences in the total number of hospital admissions (63 for CDE and 40 for CP, p=0.0025). This study failed to demonstrate any benefit in PFS with CP compared with CDE. CP was associated with significantly less haematological toxicity, leading to 37% less hospital admissions for febrile neutropaenia.

RESUMO

BACKGROUND: Results of high-dose chemo-radiotherapy (CRT), using the treatment schedules of EORTC study 08972/22973 or radiotherapy (RT) alone were analyzed among all patients (pts) with Non Small Cell Lung Cancer (NSCLC) treated with curative intent in our department from 1995-2004. MATERIAL: Included are 131 pts with medically inoperable or with irresectable NSCLC (TNM stage I:15 pts, IIB:15 pts, IIIA:57 pts, IIIB:43 pts, X:1 pt). TREATMENT: Group I: Concomitant CRT: 66 Gy/2.75 Gy/24 fractions (fx)/33 days combined with daily administration of cisplatin 6 mg/m(2): 56 pts (standard).Group II: Sequential CRT: two courses of a 21-day schedule of chemotherapy (gemcitabin 1250 mg/m(2) d1, cisplatin 75 mg/m2 d2) followed by 66 Gy/2.75 Gy/24 fx/33 days without daily cisplatin: 26 pts.Group III: RT: 66 Gy/2.75 Gy/24 fx/33 days or 60 Gy/3 Gy/20 fx/26 days: 49 pts. RESULTS: The 1, 2, and 5 year actuarial overall survival (OS) were 46%, 24%, and 15%, respectively.At multivariate analysis the only factor with a significantly positive influence on OS was treatment with chemo-radiation (P = 0.024) (1-, 2-, and 5-yr OS 56%, 30% and 22% respectively). The incidence of local recurrence was 36%, the incidence of distant metastases 46%.Late complications grade 3 were seen in 21 pts and grade 4 in 4 patients. One patient had a lethal complication (oesophageal). For 32 patients insufficient data were available to assess late complications. CONCLUSION: In this study we were able to reproduce the results of EORTC trial 08972/22973 in a non-selected patient population outside of the setting of a randomised trial. Radiotherapy (66 Gy/24 fx/33 days) combined with either concomitant daily low dose cisplatin or with two neo-adjuvant courses of gemcitabin and cisplatin are effective treatments for patients with locally advanced Non-Small Cell Lung Cancer. The concomitant schedule is also suitable for elderly people with co-morbidity.
