Objectives: To review the outcomes of treatment in patients with pulmonary sarcomatoid carcinoma (PSC) treated at the University of Cincinnati Medical Center (UCMC).Results: There was no significant difference in survival of patients treated with chemotherapy alone (median, 256 days) compared to patients not undergoing treatment (median, 205.5 days). Patients who underwent surgery and adjuvant chemotherapy showed a trend in improvement of survival (median, 457.6 days). Patients requiring only surgery had the longest OS of 713.5 days.Conclusions: Systemic chemotherapy alone did not improve survival in patients with PSC. Surgery provides the greatest overall survival benefit and adjuvant chemotherapy may also improve survival.Methods: From 2000 to 2014, twenty-five patients with pathologically confirmed PSC were treated at UCMC. The outcomes were retrospectively analyzed by treatment with overall survival (OS) as the endpoint.www.impactjournals.com/oncotarget/
Benign metastasizing leiomyoma (BML) is a rare disease that usually occurs in women of reproductive age. They typically have history of uterine leiomyoma treated with hysterectomy. BML can metastasize to distant organs, with the lung being the most common organ. We report two patients who presented with benign metastasizing leiomyoma to the lung. Our first case was a fifty-two-year-old female who presented with multiple lung masses, with a past medical history of uterine leiomyoma who underwent hysterectomy 17 years ago. A CT-guided biopsy showed benign appearing spindle cells and pathology confirmed her diagnosis with additional positive estrogen/progesterone receptor stains. Our second case was a fifty-six-year-old female who presented with multiple cavitary pulmonary nodules. She subsequently underwent a video-assisted thoracoscopic surgery (VATS) with wedge resection of one of the nodules. Pathology confirmed the diagnosis based on morphology and immunohistochemical staining strongly positive for estrogen/progesterone receptors. Benign metastasizing leiomyoma is a rare condition which may affect women of reproductive age. This should be considered in the differential in patients who present with multiple pulmonary nodules, especially with a history of uterine leiomyoma. Additional stains, such as estrogen/progesterone receptors, may need to be done to confirm the diagnosis.
More studies are warranted into the use of vimentin as an emerging useful marker for early diagnosis, aggressive transformation relapse, and prognostication of NSCLC. It may have therapeutic value in NSCLC as observed in other cancers.
Background. Thyroid metastases are rare. Clinically, they represent less than 4% of thyroid malignancy in clinical studies. Aim. To assess various presentations and therapy for patients with lung cancer metastatic in the thyroid. Materials and Methods. We report a case of metastatic adenocarcinoma of the lung to the thyroid. We reviewed similar reports through PubmMed search from 1997 until 2013. Case Presentation. A 48-year-old lady was seen in the clinic for an adenocarcinoma of left upper lobe (LUL) of the lung; she received neoadjuvant chemotherapy then LUL lobectomy. After 9 months she presented with diffuse goiter initially believed to be a solitary metastatic lesion as it was positive for adenocarcinoma of lung origin on histopathological exam with TTF-1 positivity. Unfortunately, PET scan showed additional mediastinal lymphadenopathy. Conclusion. The treatment strategy for metastatic thyroid disease is based on a multidisciplinary approach, where thyroidectomy would have been considered in case of a solitary metastatic involvement, but further metastatic workup is mandated to direct further systemic therapy versus palliative radiation therapy.
Large cell neuroendocrine cancer (LCNEC) of the lung exhibits morphological and immunohistochemical characteristics of both neuroendocrine and large cell carcinomas. No defined optimal therapy has been described for this subset of patients and the question of whether these patients should be treated with non-small cell lung cancer (NSCLC) treatment protocols, according to the National Comprehensive Cancer Network (NCCN) guidelines, or with small cell lung cancer (SCLC) due to histological and clinical similarities is still uncertain. We conducted a retrospective review of patients identified with diagnosis of LCNEC of the lung at the University of Cincinnati Cancer Center from the year 2002 to 2012 to determine which treatment approach resulted in improved outcomes in this rare category of disease. Patients who received chemotherapy whether NSCLC (group A) or SCLC (group B) protocols did not show significant changes in OS (P=0.911). Meanwhile, patients who underwent surgery (group C) had better OS compared to groups A and B (P= 0.027 and 0.024, respectively). This analysis reveals that outcomes for SCLC or NSCLC treatment strategies in LCNEC patients did not result in survival advantages and future research should be addressing it as a separate entity.
