Current Evidence for Stereotactic Body Radiotherapy in Lung Metastases

Lung metastases are the second most common malignant neoplasms of the lung. It is estimated that 20–54% of cancer patients have lung metastases at some point during their disease course, and at least 50% of cancer-related deaths occur at this stage. Lung metastases are widely accepted to be oligometastatic when five lesions or less occur separately in up to three organs. Stereotactic body radiation therapy (SBRT) is a noninvasive, safe, and effective treatment for metastatic lung disease in carefully selected patients. There is no current consensus on the ideal dose and fractionation for SBRT in lung metastases, and it is the subject of study in ongoing clinical trials, which examines different locations in the lung (central and peripheral). This review discusses current indications, fractionations, challenges, and technical requirements for lung SBRT.     

Primary liposarcoma of the lung: Report of a case

We reported one case of a primary liposarcoma of the lung which has been reported only in six cases to date worldwide, and we added some documented study. A 49-year-old female complained of exertional dyspnea with about 100 ml of hemoptysis. The chest X ray showed a coin lesion at the left upper field. After left pneumonectomy, the histological examination revealed liposarcoma of the lung. Six months after the operation, she died from severe dyspnea; the autopsy revealed the relapse of liposarcoma in the right lung, and no liposarcomas in other organs. This is the seventh case according to a worldwide review of the literature.     

Amylase-producing lung cancer

A bronchioloalveolar carcinoma of lung associated with hyperamylasemia occurring in a 40-year-old woman is described. Another 13 cases of such a tumor from the English literature are reviewed. A majority of the lung tumors associated with hyperamylasemia were adenocarcinomas. When the amylase isoenzymes were determined, the amylase appeared to be salivary-gland type (S-type). Electron microscopic studies had revealed membrane-bound electron-dense granules within the tumor cells.     

Lymphadenectomy during pulmonary metastasectomy: Impact on survival and recurrence

Background and Objectives: Lymphadenectomy during pulmonary metastasectomy (PM) is widely carried out. We assessed the potential benefit on patient survival and tumor recurrence of this practice. Methods: One hundred eighty-one patients undergoing a first PM were studied. Eighty-six patients (47.5%) underwent lymphadenectomy (L+ group) whereas 95 (52.5%) did not undergo nodal harvesting (L−group). Main outcomes were overall survival (OS) and disease-free survival (DFS). Median follow-up was 25 months (interquartile range [IQR], 13-49). Results: At follow-up 84 patients (46.4%) died, whereas 97 (53.6%) were still alive with recurrence in 78 patients (43%). There was no difference in 5-year survival (L+ 30.0% vs L− 43.2%; P = .87) or in the 5-year cumulative incidence of recurrence (L + 63.2% vs L−80%; P = .07) between the two groups. Multivariable analysis indicated that disease-free interval (DFI) less than 29 months (P < .001) and lung comorbidities (P = .003) were significant predictors of death. Metastases from non-small–cell lung cancer increased the risk of lung comorbidities by a factor of 19.8, whereas the risk of DFI less than 29 months was increased nearly 11-fold. Competing risk regression identified multiple metastases (P = .004), head/neck primary tumor (P = .009), and age less than 67 years (P = .024) as independent risk factors for recurrence. Conclusion: Associated lymphadenectomy showed not to give any additional advantage in terms of survival and recurrence after PM.     

Bleomycin-associated pulmonary fibrosis: rapidly fatal progression without chest radiotherapy

Two patients with carcinoma of the tonsil were treated with bleomycin (396 and 224 units, respectively) but not with radiotherapy. Respiratory insufficiency led to death 45 and 52 days, respectively, after onset of therapy. Chest radiographs before bleomycin therapy revealed no evidence for lung disease. Postmortem examinations showed severe interstitial and intraalveolar pulmonary fibrosis. Comparably rapid progression from radiographically normal pulmonary parenchyma to fatal fibrosis has been documented previously only in patients with thoracic neoplasia as well as, in all but one instance, either prior or concurrent chest radiotherapy. These two cases indicate that chest radiotherapy is not a necessary cofactor for the development of rapidly progressive, fatal, diffuse interstitial pulmonary fibrosis after bleomycin therapy.     

NaPi2b expression in a large surgical Non-Small Cell Lung Cancer (NSCLC) cohort

BackgroundNaPi2b is a multi-transmembrane sodium-dependent phosphate transporter expressed at normal levels in several organs, including lung. High expression levels have been reported in various tumors including breast, thyroid, ovarian and non-small cell lung cancer. To date evaluation of NaPi2b expression has mostly been restricted to smaller lung cancer cohorts.MethodsAnalyses were performed on archival formalin fixed paraffin embedded primary tumor specimens from patients who had undergone curative intent resection at an Australian tertiary hospital. Tissue microarrays were constructed and stained with the chimeric anti-NaPi2b antibody, MERS67. Semi-quantitative H-scores (range 0 – 300) were calculated for each core tissue sample (H-score = % tumor cells staining for NaPi2b multiplied by staining intensity). An overall average H-score was reported for each specimen, with a cut-off score of 50 considered positive.ResultsOf 438 cases, high NaPi2b expression was observed in 151 (34.5%) overall, high expression in 137 of 208 (65.9%) adenocarcinoma cases, and 5 of 179 (2.8%) squamous cases (P < .0001). High NaPi2b expression was associated with female sex, EGFR or KRAS mutation, and TTF1 positivity (adenocarcinoma cases only). High NaPi2b expression was associated with improved overall survival (median 54 vs. 35 months, P = .029).ConclusionHigh NaPi2b expression was noted in a significant subset of adenocarcinoma cases, and in particular amongst those who were TTF1+, or exhibited EGFR or KRAS mutations. This agrees with earlier reports and highlights the significance that NaPi2b may have a role as a possible target for delivery of cytotoxic agents via antibody-drug conjugate models for some patients with lung adenocarcinoma.     

Importance of biologic status to the postoperative prognosis of patients with stage III nonsmall cell lung cancer

The prognosis of patients with stage III nonsmall cell lung cancer was studied, with special attention to their biologic status prior to lung resection. The biologic status was estimated from the neutrophil/lymphocyte ratio in the peripheral blood, serum albumin level, and erythrocyte sedimentation rate. Among 46 patients who underwent potentially curative operations, 31 cases of biologic status A or B (more than two parameters normal) revealed 37.6% of a 5-year survival rate, whereas there was no 5-year survivor in 15 cases of biologic status C or D (more than two parameters abnormal). Of the 5-year survival rate in T3N0 disease of biologic status A or B, the 60% surviving (of 10 cases) was in marked contrast to the same stage disease of biologic status C or D where only 1 patient (of 10 cases) was still surviving at more than 30 months. In 30 patients with T3N0, T3N1, and T2N2 diseases of biologic status A or B, where long-term survivors were derived, the 5-year survival rate in 30 patients of biologic status A or B was 36.6% in contrast to no long-term survivor in the same stage diseases of biologic status C or D (n = 25). We conclude that surgical results in stage III nonsmall cell lung cancer will be beneficial in patients of biologic status A or B, but nonbeneficial in patients with the same stage of biologic status C or D.
