Clinical Lung Cancer | Year: 2012
This study aims to determine prognostic factors for patients who have nonsmall-cell lung cancer (NSCLC) that is treated with definitive chemoradiation therapy. Seventy-eight patients has been treated with radiation therapy and concomitant or sequential chemotherapy between 2000 and 2005. Paraffin-embedded biopsy specimens were obtained before treatment from 73 patients and reviewed by two independent pathologists. Complete follow-up data were collected. The impact of clinical and pathological factors and treatment modality on survival was studied using the χ 2 and Fisher exact tests. A multivariate analysis was performed using the Cox proportional hazard model. Seventy-three patients were evaluated, 58 men and 15 women. Median age was 62 years. Most had locally advanced disease (42 stage IIIB and 24 stage IIIA), whereas 7 were medically inoperable stage I-II patients. Lymphovascular invasion (LVI) was identified in 20 biopsy specimens (27.4 %). Radiotherapy delivered a median dose of 66 Gy (range, 60 to 70 Gy). The median overall survival was 20.5 months. Relapse-free and overall survival were significantly higher in the concomitant arm than in the sequential arm (P =.025 and P =.031, respectively). We found an independent association between the presence of LVI and both the risk of death with an adjusted hazard ratio (HR) of 2.69 (95% confidence interval [CI] 1.50-4.83) and the risk of metastatic progression (adjusted HR = 3.01; 95% CI 1.58-5.72). The presence of LVI on stage III NSCLC biopsy specimens was the only independent prognostic factor for poor outcome and may, therefore, be helpful in identifying patients at high risk of metastatic disease. © 2012 Elsevier Inc.

The primary intracranial development of olfactory neuroblastomas, outside olfactory epithelium, is rare. We report a case of primary sellar neuroblastoma without any aggressive histopathological features, managed solely surgically without adjuvant therapy, with good outcomes at 3 years. Primary sellar neuroblastomas mostly occur in women in the 4th decade with a context of a non-secreting pituitary tumour. Diagnosis is made on histopathological examination (small cells, fibrillary intercellular background, strong immunoreactivity for neurons markers, negative immunoreactivity for anterior pituitary hormones). Management is based on surgery. Adjuvant treatment is not consensual, largely depends on patient's conditions and aggressive histopathological features. © 2012 Elsevier Masson SAS.

Background: The first-choice treatment of thyrotropin (TSH)-secreting pituitary adenomas is surgical adenomectomy, with 40-60% of patients cured after surgery. The presence of somatostatin receptors on the adenomatous cells suggests that first-generation somatostatin analogs (octreotide, lanreotide) could be used as an adjuvant treatment to surgery for TSH-secreting pituitary adenomas. The aim of this study is to describe the efficacy and safety of primary medical treatment with first-generation somatostatin analogs in patients with a TSH-secreting pituitary adenoma. Methods: Retrospective study on 7 patients (5 women, 2 men) aged 57±14 years with pure TSH (n=4) or mixed TSH/GH (n=3) secreting pituitary adenomas primarily treated with first generation somatostatin analogs. Magnetic resonance imaging revealed a microadenoma in 3 patients and a macroadenoma in 4 patients. The follow-up period was 8.5±7.3 years. Results: At initial diagnosis, the patients presented with thyrotoxicosis with elevated free thyroxine (26.5±6.5 pg/mL) and free triiodothyronine (7.3±0.9 pg/mL) levels and a mean TSH of 4.3±1.4 mU/L. During somatostatin analog treatment, free thyroid hormones and TSH levels normalized after 4.4±3.9 and 7.0±8.4 months, respectively. At the time of the last visit, 6 patients were biochemically controlled. Adenoma volume decreased in 6 patients and a decrease in adenoma volume persisted in 2 patients several years after initiation of somatostatin analog treatment. Safety of treatment was good and no patients discontinued somatostatin analogs due to side effects. Conclusion: This study confirms the efficacy of primary medical treatment with first-generation somatostatin analogs in terms of hormonal control and tumor volume reduction in patients with TSH-secreting pituitary adenomas, and its good safety profile. First-generation somatostatin analogs may serve as a medical alternative to surgical treatment, especially in patients where surgery is contraindicated or in subjects presenting with invasive macroadenomas that render complete surgical resection difficult. © Copyright 2015, Mary Ann Liebert, Inc.
