The Treatment of Metastatic Non-small Cell Lung Cancer (NSCLC) in New Era of Personalised Medicine. Brain metastases (BM) are a common and lethal complication of non-small cell lung cancer (NSCLC), which portend a poor prognosis.
Despite these grim realities, there is room for optimism among identifiable subsets of these patients.
Several variables have been established of prognostic importance in determining potential outcomes for patients harboring BM. Since then, several other scoring classifications have been described (4, 8–11) as shown in Table 1. Early integration of palliative care in the management of metastatic NSLCC has been demonstrated to improve both quality of life and mood, and is associated with improved survival despite less aggressive end of life treatment (15).
Up to few decades ago, surgical resection was mainly used to establish a diagnosis or to alleviate mass-effect symptoms.
In two of these trials (17, 18), a survival benefit was reported for patients undergoing the combined approach. It should be mentioned that all of these randomized studies had small patient numbers and did not include relatively radiosensitive tumors such as small cell lung cancer, lymphoma, myeloma, and germ cell tumors.
Despite these limitations, the current level 1 evidence supports the use of WBRT post-surgical resection in patients with a single, resectable lesion, good performance, and limited extracranial disease. A follow-up trial by Patchell and colleagues (24) addressed the real need of WBRT post-resection of a single brain metastasis.
One major concern with the use of WBRT is the risk of neurocognitive deficits, particularly short-term memory. Recent approaches to reduce the potentially negative effects of WBRT on cognitive function include the concomitant use of memantine (20) and hippocampal sparing during WBRT (21). Stereotactic radiosurgery (SRS) delivers a single high dose of irradiation to the target volume while avoiding the surrounding normal tissues. Despite differences in patient selection and treatment design, all trials consistently show no significant difference in survival, but have shown a significant reduction in intracranial failures and death from brain causes. Whether SRS can replace WBRT in newly diagnosed BM remains to be determined and treatment decisions should be individualized taking into consideration the patients’ wishes, age, intra and extracranial disease extent, and prognosis. Due to the failure of most drugs to cross the intact blood–brain barrier (BBB), the role of chemotherapy in the treatment of BM has been viewed critically (2). More recently, two phase II trials have examined the use of cisplatin and pemetrexed for the treatment of NSCLC with BM. The use of drugs targeting the proteins of mutated EGFR and anaplastic lymphoma kinase (ALK) genes has become standard of care in the systemic treatment of metastatic NSCLC (42). The ALK-inhibitor crizotinib has also demonstrated strong anti-tumor activity systemically. The mutation status of tumors is usually derived from biopsies obtained at extracranial sites, and thus, does not necessarily guarantee a mutation in the sub-clones within the brain. Just as targeted therapy with EGFR and ALK inhibitors is highly active systemically among molecularly selected NSCLC patients, there is mounting evidence that this is also true for activity intra-cranially. The management of patients with BM has evolved over the years from an under-studied area to a field of exciting active research.
The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Lung cancer is a disease characterized by uncontrolled cell growth in tissues of the lung with a potential tometastasize, spread beyond lungs, to nearby tissues and later to other parts of the body. There are two main types of lung cancer, small-cell lungcarcinoma and non small cell lung carcinoma. Lung cancer is the third most common site of origin of metastatic cancer deposits in bone after breast and prostatecancer. Lung cancer with bone metastasis is one of the most aggressive tumors and has unfavorable prognosis.Average survival after diagnosis is about 6months.

When lung cancer travels through lymphatic system, they reach the lymph nodes where they can lodge and grow. The lymph nodes commonly involved includes intrapulmonary, mediastinal and extra thoracic lymphA nodes. The regional lymph nodes, when affected can be surgically removed, but when the distant sites areinvolved, chemotherapy or radiation becomes necessary. The prognosis depends on several factors like the site of the node involved, type of lung cancer, sizeA of tumor, whether tumor has spread to other areas and the general health of the patient.
Metastasis to adrenals does not usually cause symptoms, usually detected during routine scans. Fractionated stereotactic radiotherapy (FSRT) alone or combined with whole brain radiation therapy can be used to treat intracranial metastases.

In addition, their management implies several challenges including preservation of neurological and neurocognitive function during surgery or radiation-therapy, minimizing iatrogenic complications of supportive medications, and optimizing drug delivery across the blood–brain barrier.
A recent published series of NSCLC patients with synchronous BM receiving surgery or radiosurgery to the brain and aggressive management of their extracranial disease reported a median overall survival (OS) of 12.1 months (5).
In 1997, the Radiation Therapy Oncology Group (RTOG) performed a recursive partitioning analysis (RPA) from a historical database of 1200 patients treated with whole-brain radiation therapy (WBRT) from three RTOG BM trials and published a prognostic scoring system (7). All these classifications have limitations, but are able to consistently prognosticate outcomes based on the defined scoring. In addition, microarray-derived gene signatures provide the potential for even greater prognostic ability (14). In addition to general palliative measures, patients with BM often necessitate additional supportive medications such as steroids and anti-seizure medications. More recently, its definitive role in improving disease control for patients with single, resectable metastasis has been shown to be significant.
Also, these trials were not specific for NSCLC patients, although this histology was the predominant one in all trials. For patients with multiple metastatic lesions, poor performance scores, and extensive systemic disease an evidence-based recommendation for the combined approach cannot be made. The rationale for treating the whole brain is based on the presumption that micro-metastatic deposits of tumor cells are present elsewhere in the brain.
Unfortunately, the real rate and magnitude of neurocognitive deficits post-WBRT has not been properly studied. Memantine, a potential neuroprotector, was used during EBRT in a recent RTOG randomized trial (20).
A randomized trial conducted by the RTOG (22) showed that the addition of SRS to WBRT was superior to WBRT alone in patients with a newly diagnosed single brain lesion. First, there is evidence that the BBB of BM is disrupted, as evidenced by the presence of peritumoral edema and the accumulation of contrast media during computed tomography or magnetic resonance assessments (38, 39). In one trial, 43 chemo-naive NSCLC patients (93% non-squamous histology) with BM received up to six cycles of cisplatin and pemetrexed at standard doses (40). In first-line clinical trials of the EGFR-targeted drugs gefitinib, erlotinib, and afatinib, objective response rates (ORRs) of 55–83% were observed, mostly clustering above 70% (43).
In a phase III second-line NSCLC trial of patients with ALK-rearranged tumors randomized to receive crizotinib vs.
However, a Chinese study of 136 NSCLC patients with resected BM, in which an EGFR mutation was identified in 57% of the BM, found a concordance rate of 93.3% in the EGFR mutation status between the primary tumor and BM (50). A recent review has examined the use of the EGFR inhibitors gefitinib and erlotinib in BM among NSCLC patients (6). Lung Cancer Never Smokers Different Disease xALKORI is indicated for the treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors are anaplastic lymphoma kinase (ALK)-positive as detected by an FDA-approved test.

Despite these challenges, advancements in combined modality approaches can deliver hope of improved overall survival and quality of life for a subset of NSCLC patients with BM. Improved surgical techniques and radiation therapy (RT) technology, as well as more effective systemic treatments and multimodality approaches have led to these superior outcomes. Three scoring classes were identified based on patients’ Karnofsky performance score (KPS), age, status of primary tumor, and extent of extracranial disease (Table 1). Irrespective of the scoring classification used, age, performance status, number of brain lesions, and the presence of extracranial metastases are the variables that better define prognosis.
However, many of these biomarkers require further validation, and are not yet ready for entry into routine clinical practice.
Corticosteroids can be vital drugs in the control of intracranial edema from BM and the relief of related symptoms. Three randomized studies (17–19) have addressed the potential therapeutic value of surgical resection by comparing surgery followed by WBRT vs. WBRT is the most frequently used treatment for the management of BM and its use is associated with improvement in neurologic symptoms and decreased neurologic death (25).
It has been shown that over 90% of patients with BM had impairment in one or more neurocognitive tests at baseline and prior to WBRT (32).
A survival benefit was not seen for patients with two or three metastatic lesions, although local brain control was significantly improved with the addition of SRS. Second, there is evidence of intracranial tumor response, even to drugs that in healthy systems have little central nervous system penetration.
This suggests that primary tumor EGFR status is a very good surrogate for EGFR mutation status of the BM. Additional areas of active research include techniques to preserve neurocognitive functions with radiotherapy (20, 52), improving the detection and clinical utility of circulating tumor cells (53), and novel systemic approaches including immunotherapy alone (54, 55) or in combination with radiotherapy (56), anti-metabolic agents (57), anti-angiogenesis drugs (58), and novel targeted therapies for a growing list of oncogenic mutations (59).

The most commonly affected bones are theA spine, ribs, pelvis and long bones of hands and feet. The regional lymph nodesA becomes involved in the earlier stages before they reach the lymph nodes in the distant regions. Previous studies suggested that prophylactic cranial irradiation (PCI) may reduce or delay the onset of BM.
Moreover, new drugs harnessing our greater understanding of tumor biology promise to build on this hope. Moreover, many will suffer considerable loss of autonomy due to neurocognitive and functional deficits, as well as morbidity associated with medications such as steroids and anti-epileptic drugs.
Moreover, renewed hope has emerged from the use of small-molecule drugs targeting oncogenic mutations, which have shown promising activity both extra-cranially and intra-cranially (6). Given the high heterogeneity of the BM patient population, one should not rely exclusively on these indices when assessing the management for such patients.
However, in light of their considerable short- and long-term side effects, steroids should be used judiciously.
The group receiving post-operative WBRT experienced a significantly lower rate of brain recurrence (18 vs. Proponents of WBRT argue that it is the disease progression in the brain not treated by WBRT that, in fact, compromises the patient’s neurocognitive function. Given its focal delivery of irradiation, there have been concerns that its isolated use could lead to an increased rate of failure elsewhere in the brain. In a recent review (37), the response rates (RRs) of BM to platinum-based regimens in seven clinical trials of treatment-naïve NSCLC patients were similar to those achieved extra-cranially, ranging from 30 to 50%.


The hematologic toxicities were generally mild or moderate and there were no grade 4 or higher non-hematologic toxicities.
In this same cohort of patients, the median OS was 24.5 months in the EGFR mutation group, compared to 15 months in the wild-type group. Similarly, intracranial RRs were 56 and 82% for erlotinib in clinically and molecularly selected patients, respectively. Ultimately, the optimal management strategy will employ a multi-disciplinary approach accounting for individual characteristics of both patient and tumor. The tumor in the lung sheds malignant cells directly into theA arterial blood from where they can be seeded into other suitable spots.
Small cell lung cancer most often spreads to other sites and may grow much faster than the other types. As a result between 1930 and 1960 numerous what percent lung cancer stage 4 jamich of lung cancer patients survive epidemiologic studies were undertaken to try to quantify the relationship between cigarette type of chemo for non small cell lung cancer smoking and lung cancer.
In this mini-review, we revised the management of BM in NSCLC including advancements in neurosurgery, radiation therapy, as well as systemic and supportive therapy. A comparative review of five of these prognostic indexes using an artificial neural network in patients with BM and receiving WBRT (12) suggests that the graded prognostic assessment index (10) was the most powerful in predicting survival. Of interest, 11% of patients were excluded because no metastatic disease was seen on the biopsy specimens. However, some patients develop cognitive problems that cannot be simply explained by disease progression elsewhere in the brain. However, concerns with cognitive deficits from WBRT led investigators to use SRS alone in selected patients, reserving WBRT for a later date if necessary.
On the other hand, in the Japanese trial (34), there was a significant decline in mini-mental score when SRS was given alone making the authors conclude that BM control was the most important factor for preserving neurocognitive function. This finding is consistent with other studies identifying EGFR mutation status as a positive prognostic factor among patients with BM (51). Taken together, these results highlight both robust intracranial activity and the importance of EGFR mutation status as a predictor of intracranial response. Lung cancer is formed when the cells of the lungs grow in an uncontrolled way this creats a lump or a tumour which can either be malignant (cancerous) or Preventions are available in many different methods with the help of government and professional study lung cancer is treatable and curable. It was a needle as big as the inside of a pen that they pushed through my hip bone, and sucked out bone stuff. Symptoms from the spread of lung cancer may be noticed before symptoms occur from the lung cancer itself. The authors reported a statistically significant improvement in survival (median survival: 40 vs. Approximately 60% of patients will experience a complete or partial response with a similar rate for symptoms improvement, though usually transient. Late effects from WBRT are usually seen after 6 months post-treatment and are secondary to white matter damage.
Although this was a single arm trial, the declines in cognitive function are less than what was observed from historical controls. In the same review, three trials using temozolomide achieved a RR of only 0–10%, suggesting that the selection of chemotherapy drugs should be based mainly on their established anti-tumor activity to extracranial sites, and not on considerations of BBB penetrance.

Considering that many patients will not survive beyond 6 months, it is plausible to consider that cognitive deficits would be seen in larger proportion of patients should they survive longer. Other symptoms include hypercalcaemia, painful thickening of the long and short tubular bones. However, recurrent lesions were reported and the repeated WBRT will cause intolerable side-effect. The most critical factor in determining the survival rate is the stage at the time of diagnosis. Although OS was not different between groups, importantly, post-operative WBRT significantly prevented death from neurologic causes (14 vs.
Most of the previously published randomized controlled trials did not include patients with BM from SCLC.
SRS treatment strategy include traditional single dose SRS and multi-dose SRS up to five doses. Ronald Natale, director of the Lung Cancer Research Program at Cedars-Sinai Medical Center in Los Angeles. Fractionated stereotactic radiotherapy (FSRT) may be useful for treatment of patients with metastatic lesions larger than 3 cm in diameter. If intracranial metastases recurred or new lesions developed FSRT is still able to be used as a salvage option.
However, the therapeutic efficacy of salvage or primary FSRT in patients with BM from SCLC remains unclear. The median OS after FSRT for recursive partitioning analysis (RPA) class I, II, III patients were 19, 10, 6 months respectively [Figure 3]. The median overall survival was 10 months for all patientsClick here to viewFigure 2: Comparison of median overall survival for salvage fractionated stereotactic radiotherapy (FSRT) group (group 1 or 3) and primary FSRT group (group 2 or 4).
Of these 41, 18 (40%) died of BM, 20 (44.4%) died of extra-cranial disease progression and 3 died of other causes (2 patients had died from a lung infection, 1 patients had died from an unknown cause). One patient recovered after a short course of steroids treatment.Totally 35 patients underwent follow-up MRI.
Repeat WBRT treatment for recurrent lesions may cause severe complications such as neurocognitive impairment, diffuse white matter injury and even brain necrosis. However, there was significant survival differences between the two groups from the diagnosis of SCLC (22 months vs. The salvage group survives longer because a subgroup of patients may be responsive to the systemic treatment.
WBRT may allow FSRT to be deferred for subsequent salvage treatment without adverse sequelae. To the best of our knowledge, a series of studies have reported the results of SRS treatment of patients with BM from SCLC. KPS and combined treatment involving WBRT and SRS within 4 weeks were identified as significantly predictors of increased OS.
In a study of 27 patients who had recurrence BM from SCLC after WBRT, the authors reported the median survival from SRS was 4.5 months and the LC rate was 81%.
The authors found that tumor volume, pre-operative KPS score and time interval between lung cancer diagnosis and development of BM were strongly associated with time of survival. The median OS time was 5.9 months and the LC rate at 12 and 24 months were 54% and 40%, respectively.
The status of extra-cranial disease at the time of salvage and the use of post-SRS chemotherapy were independent predictors for increased OS time. New metastases outside the treated area developed in 60% of assessable patients at a median 3.5 months. Significant prognostic factors for survival that were identified in that patient population were KPS, number of BM, diameter of the largest tumor and carcinomatous meningitis.
In consistent with previous reports, we also demonstrated that the RPA was significant prognostic factor for SCLC BM.
We found that patients with RPA I class had a better outcome than those with RPA II, III.The results of our study suggested that FSRT was a safe, effective and viable therapeutic option for SCLC BM.
However the FSRT was most likely used after the WBRT failure in the current clinical practice. Despite FSRT treatment, half of patients had succumbed to progression of their systemic disease. Therefore, control of extra-cranial and systemic disease was important to prolong survival in patients with BM from SCLC.The central nervous system has been considered a sanctuary site because of the limitations of drug delivery imposed by the blood-brain barrier (BBB). In a study of 24 asymptomatic BM patients who were treated with the same chemotherapy regimen (cyclophosphamide, doxorubicin and etoposide), the author reported that 73% of these patients with extra-cranial disease responded to chemotherapy based on MRI findings.
The combined modality group had better radiologic response than the teniposide-alone group (57% vs. The first site of progression was the brain in 17% in the combined-modality group compared with in 43% in the teniposide-alone group. FSRT is an effective, minimally invasive method that could be used for treatment of BM from SCLC.
