therapy-related myelodysplastic syndrome (t-MDS) in breast cancer patients exposed to chemotherapy and/or radiotherapy is significantly high compared to that in other cancer patients. This report reviews the use of hypomethylating agents (HMAs) to treat a 57-year-old woman newly diagnosed with MDS during palliative chemotherapy for metastatic breast cancer. Over a period of 6 years, the patient received several DNA-damaging chemotherapeutics including doxorubicin, cyclophosphamide, and paclitaxel. Repeated thrombocytopenia was the main reason for suspecting secondary hematologic malignancy. She was diagnosed with t-MDS based on bone marrow examination and her treatment history for breast cancer. While azacitidine was originally administered to stabilize MDS, it also stabilized the patient's lung and lymph node metastases without any major toxicity. Therefore, the current case highlights the promising effects of HMAs for treating t-MDS following heavily pretreated breast cancer.]]>

The lung is the second most common site of neuroendocrine tumors (NETs). Typical and atypical carcinoids are low-grade NETs of the lung. These rare tumors have received little attention and education is needed for treating physicians. The article describes the classifcation of lung NETs, the epidemiology and pathological characteristics. When lung NETs are diagnosed at an early stage, surgical intervention is often curative. For advanced lung NETs patients, different treatment methods including chemotherapy, somatostatin analogs, m-TOR inhibition, peptide receptor radioligand therapy, and biologic systemic therapy are discussed. The conclusions are generally extrapolated from the outcome of extra-pulmonary carcinoids. Prospective randomized well-designed trials are urgently needed to inform current recommendations on systemic treatment.

BACKGROUND: Advanced epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma had a high overall incidence of brain metastasis during the full course, and local brain radiotherapy combined with systemic targeted therapy may be a better strategy. This study aimed to identify the prognostic factors of EGFR-mutant brain-metastatic lung adenocarcinoma patients who received EGFR-tyrosine kinase inhibitors (EGFR-TKIs) in combination with gamma knife radiosurgery. METHODS: Retrospective analysis of EGFR-mutant lung adenocarcinoma patients with brain metastases which developed at initial diagnosis or during EGFR-TKIs treatment period were performed. Intracranial progression free survival (PFS) was statistically analyzed between different subgroups to find out the prognostic factors including gender, age, smoking history, extracranial metastasis, EGFR mutation type, size and number of intracranial lesions, carcino-embryonic antigen (CEA) level, lung-molGPA score and so on. RESULTS: A total of 74 EGFR-mutant brain-metastatic lung adenocarcinoma patients were enrolled in this study, with median intracranial PFS of 14.7 months. One-year intracranial-progression-free rate was 58.5%, and two-year rate was 22.2%. Univariate survival analysis showed that patients with lower CEA level at initial diagnosis (<10 ng/L)(16.9 months vs 12.6 months, P=0.012) and smaller intracranial lesions (<2 cm)(15.4 months vs 10.8 months, P=0.021) and higher lung-molGPA score (>3)(15 months vs 12.6 months, P=0.041) were prone to have a superior intracranial PFS. Multivariate analysis showed that CEA≥10 ng/mL and intracranial lesion≥2 cm were the independent risk factors of intracranial PFS. CONCLUSIONS EGFR-TKIs in combination with gamma knife radiosurgery was an efficient treatment option to control the cranial tumor lesion. CEA≥10 μg/L at initial diagnosis and intracranial lesion≥2 cm were the risk factors of EGFR-mutant brain-metastatic lung adenocarcinoma patients receiving EGFR-TKIs in combination with gamma knife radiosurgery.

Standard treatment for resectable IIIa/N2 non-small-cell lung cancer (NSCLC) is still under debate. Optional treatments include chemotherapy, radiotherapy and surgery, other options include target therapy and immunotherapy. Multidisciplinary treatment has therefore been emphasized by various clinical trials, including bimodality strategy which has been defined as chemotherapy plus surgery or chemotherapy plus radiotherapy, and trimodality treatment which refers to chemotherapy plus surgery and radiotherapy. However, there is still no consensus on the optimal strategy on treating resectable IIIa/N2 NSCLC. Therefore, we reviewed a series of phase II and III clinical trials as well as some meta-analyses and case reports to compare the efficacy of different strategies on survival of cN2 NSCLC, and concluded that for resectable IIIa/N2 NSCLC surgery is recommended, and that strategy of chemotherapy plus surgery may not achieve better survival than that of chemotherapy plus radiotherapy. Size of tumor as well as lymph nodes should be taken into account when choosing optimal therapy, so that promising individualized strategy could be given to patients with resectable stage IIIa/N2 NSCLC.

PURPOSE: It is unclear whether adding concurrent chemotherapy (CT) to definitive radiotherapy (RT) following induction CT is a tolerable and cost effective treatment for non-small-cell lung cancer (NSCLC) patients aged 70 years or older with comorbidities. This study evaluated the actual clinical outcomes between concurrent chemoradiotherapy (CCRT) and RT alone following induction CT or not in patients (≥70 years) in a single institution’s clinical practice. MATERIALS AND METHODS: A total of 82 patients with unresectable stage III NSCLC between 2004 and 2016 were retrospectively analyzed. Their treatment tolerance and clinical outcomes such as overall survival (OS), locoregional recurrence (LRR), treatment toxicities and distant metastasis (DM) were evaluated. Early mortality rates were also evaluated as 4-month mortality after RT. RESULTS: Fifty-four patients received CCRT and 28 patients received RT alone. Induction CT before RT was performed for 68.5% and 50.0% in CCRT and RT alone groups. Treatment tolerance was significantly worse in CCRT (p = 0.046). The median survival was 21.1 and 18.1 months for CCRT and RT alone, which was not statistically significant. LRR and DM were also not different. Most early deaths after CCRT were attributed to non-cancer-related mortality. Acute esophagitis of grade ≥2 occurred more following CCRT (p = 0.017). In multivariate analysis, a Charlson Comorbidity Index (CCI) of ≥5 and a weight loss of ≥5% after RT were associated with poor OS. The factors adversely affecting 4-month survival were a CCI of ≥5 and CCRT. CONCLUSION: There were no significant differences in OS, LRR, and DM between CCRT and RT alone treatment in elderly patients. However, there was a poorer tolerance and higher incidence of acute esophagitis in the CCRT group. Specifically, when the patients had a CCI of ≥5, RT alone seems to be reasonable with a low probability of early death.

BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR), indexes of systemic inflammation, have been associated with worse survival for many types of cancer. The aim of this study is to investigate the impact of NLR and PLR on overall survival (OS) and to explore the value of changes in the NLR and PLR with treatment as a response indicator in non-small cell lung cancer (NSCLC). METHODS: A total of 68 NSCLC patients in Peking University Third Hospital were eligible for retrospective analysis between April 2008 and April 2015. The pretreatment and posttreatment NLR and PLR in all patients were calculated based on complete blood counts. Potential prognostic factors such as age, gender, performance status, histology, stage, response to chemotherapy, NLR and PLR were analyzed. NLR and PLR were assessed at baseline and during chemotherapy treatment. OS was calculated by the Kaplan-Meier method. Univariate and multivariate Cox regression analyses were performed to determine the associations of the PLR, NLR and clinical features with OS. RESULTS: Among the 68 cases, the values of the posttreatment NLR after two cycles of chemotherapy (NLR2) and the pretreatment NLR (NLR0) were (2.69±2.06) and (3.94±2.12), respectively. NLR2 was significantly lower than NLR0 (P=0.000). There was no difference between the pretreatment PLR (PLR0) and the posttreatment PLR after two cycles of chemotherapy (PLR2) (P<0.05). NLR2 significantly correlated with the response of first line treatment with two or four cycles of chemotherapy. The proportion of high NLR2 in the patients with progression disease was 100.0%, significantly higher than the proportion of high NLR2 in the patients with partial response or stable disease. NLR0, PLR0 and NLR2 were significantly correlated with the OS (P<0.05), but not with age, performance status, histology, stage, status and regimens of treatment (P>0.05). According to univariate analysis, the OS was significantly associated with NLR0, PLR0, NLR2, the response of 2 and 4 cycles of first line chemotherapy, status and regimens of second line treatment (P<0.05), but not with stage, status of third line or beyond treatment and radiotherapy (P>0.05). The multivariate analysis showed that NLR0 (P=0.004), the response with 4 cycles of first line chemotherapy (P=0.022) and status of second line treatment (P=0.007) were independent prognostic indicators in the 68 patients. CONCLUSIONS The study showed that NLR0 was well connected with outcomes and NLR2 was well connected with the response to first line chemotherapy in patients with advanced non-small cell lung cancer. Therefore, NLR may be a biomarker for predicting the outcomes and response of first line chemotherapy and a potential target for management of non-small cell lung cancer.

BACKGROUND: Leptomeningeal metastasis (LM) is an uncommon, but devastating complication of advanced cancer and has no standard treatment. Herein, we analyzed the clinical characteristics and outcomes of patients with solid tumors who were diagnosed with LM. METHODS: Between January 2007 and December 2017, we retrospectively analyzed the medical records of patients with solid tumors who were diagnosed with LM. RESULTS: A total of 58 patients were enrolled in this study. The median age of patients was 51 years (range, 27–72 years), and 62.1% had a poor Eastern Cooperative Oncology Group (ECOG) performance status (PS) (>2). The common types of primary tumor were breast cancer (39.7%), gastric cancer (25.9%), and non-small cell lung cancer (20.7%). Forty-two patients (72.4%) were diagnosed with LM by MRI of the brain and/or spine and cerebrospinal fluid (CSF) analysis, 14 were diagnosed by CSF analysis alone, and 2 were diagnosed by MRI alone. Treatments for LM were performed in 53 patients (91.4%), and best supportive care was provided for 5 patients (8.6%). Intrathecal chemotherapy, radiotherapy, and systemic chemotherapy were administered in 43 (74.1%), 17 (29.3%), and 24 (41.4%) patients, respectively. The median overall survival of the entire cohort was 2.4 months (95% confidence interval, 1.0–3.7). In the analysis of prognostic factors for survival, a good ECOG PS (≤2), administration of systemic chemotherapy after LM diagnosis, and a prior history of brain radiation were associated with prolonged survival. CONCLUSION: Although the prognosis of LM in patients with solid tumors is poor, systemic chemotherapy might improve survival in selected patients with a good PS.

Pheochromocytoma (PCC) is a neuroendocrine tumor that mainly arises from the medulla of the adrenal gland. Some PCCs become malignant and metastasize to other organs. For example, it typically involves skeletal system, liver, lung, and regional lymph nodes. However, only a few cases of PCC with brain metastasis have been reported worldwide. We report a case of metastatic brain tumor from PCC in South Korea in 2016. A 52-year-old man presented with headache, dizziness and motor aphasia. He had a medical history of PCC with multi-organ metastasis, previously underwent several operations, and was treated with chemotherapy and radiotherapy. Brain MRIs showed a brain tumor on the left parietal lobe. Postoperative pathology confirmed that the metastatic brain tumor derived from malignant PCC. This is the first report PCC with brain metastasis in South Korea.

PURPOSE: The outcomes and toxicities of locoregionally recurrent non-small-cell lung cancer (NSCLC) patients treated with curative radiotherapy were evaluated in the modern era. MATERIALS AND METHODS: Fifty-seven patients receiving radical radiotherapy for locoregionally recurrent NSCLC without distant metastasis after surgery from 2004 to 2014 were reviewed. Forty-two patients were treated with concurrent chemoradiotherapy (CCRT), and 15 patients with radiotherapy alone. The median radiation dose was 66 Gy (range, 45 to 70 Gy). Lung function change after radiotherapy was evaluated by comparing pulmonary function tests before and at 1, 6, and 12 months after radiotherapy. RESULTS: Median follow-up was 53.6 months (range, 12.0 to 107.5 months) among the survivors. The median overall survival (OS) and progression-free survival (PFS) were 54.8 months (range, 3.0 to 116.9 months) and 12.2 months (range, 0.8 to 100.2 months), respectively. Multivariate analyses revealed that single locoregional recurrence focus and use of concurrent chemotherapy were significant prognostic factors for OS (p = 0.048 and p = 0.001, respectively) and PFS (p = 0.002 and p = 0.026, respectively). There was no significant change in predicted forced expiratory volume in one second after radiotherapy. Although diffusing lung capacity for carbon monoxide decreased significantly at 1 month after radiotherapy (p < 0.001), it recovered to pretreatment levels within 12 months. Acute grade 3 radiation pneumonitis and esophagitis were observed in 3 and 2 patients, respectively. There was no chronic complication observed in all patients. CONCLUSION: Salvage radiotherapy showed good survival outcomes without severe complications in postoperative locoregionally recurrent NSCLC patients. A single locoregional recurrent focus and the use of CCRT chemotherapy were associated with improved survival. CCRT should be considered as a salvage treatment in patients with good prognostic factors.

In hepatocellular carcinoma (HCC), sorafenib is the only approved systemic chemotherapy, and has been applied for those with advanced HCC especially with systemic metastasis. However, the treatment results are suboptimal leaving many cases with disease progression despite the use of optimum dose. There is no established guideline for those that fail to respond to sorafenib treatment. In this case, a 46-years-old male with metastatic lung cancer from HCC experienced progression despite sorafenib treatment. Then, the patient received surgical resection of the metastatic lung mass followed by radiation therapy and achieved complete remission for 10 months after the surgical treatment and radiation therapy. Alpha-fetoprotein level was normalized and complete remission has been maintained.
