class="elsevierStyleSectionTitle" id="cestitle60">INTRODUCTION</span><p id="para10" class="elsevierStylePara elsevierViewall">Nasopharyngeal carcinoma (NPC) is a leading form of cancer in several well-defined populations, such as the natives of southern China, Southeast Asia, the Arctic, the Middle East, and North Africa (<a class="elsevierStyleCrossRef" href="#bib1">1</a>,<a class="elsevierStyleCrossRef" href="#bib2">2</a>). With advances in radiotherapy techniques, the regional control rate of NPC has increased remarkably (<a class="elsevierStyleCrossRef" href="#bib1">3</a>). In recent years, the combination of targeted medicine with intensity-modulated radiotherapy has also brought promising results for locoregionally advanced NPC (<a class="elsevierStyleCrossRef" href="#bib4">4</a>,<a class="elsevierStyleCrossRef" href="#bib5">5</a>). The majority of deaths occur not because of the tumor in the primary site but rather because of distant metastasis. Different reports have shown that approximately 17% to 54% of patients with NPC failed treatments due to distant metastases and that approximately one-third of patients presented disseminated disease at the primary diagnosis (<a class="elsevierStyleCrossRef" href="#bib4">6</a>). Bone is one of the preferred target sites for cancer metastasis. NPC has a propensity to spread to bone, and most of the patients who present with bone metastasis have an increased risk of skeletal-related events (SREs), including receiving radiotherapy for bone pain, pathological fracture, spinal cord compression and hypercalcemia, all of which result in reduced quality of life and an increased risk of death (<a class="elsevierStyleCrossRef" href="#bib5">7</a>).</p><p id="para20" class="elsevierStylePara elsevierViewall">Once bony metastasis has been diagnosed, the current standard treatment modality for these patients essentially involves cisplatin-based palliative chemotherapy with or without local radiation therapy according to the symptoms of bone pain (<a class="elsevierStyleCrossRef" href="#bib6">8</a>). Determining the early response to treatment is essential to the subsequent management in disseminated NPC patients. In the past, the tumor evaluation criteria developed by the WHO defined bone tumor response by the change of lesion size in skeletal scintigraphy and plain radiography. However, because the change in osteodestructive lesion size is always slow, this method is not useful in clinical practice (<a class="elsevierStyleCrossRef" href="#bib7">9</a>). Currently, the most scientific and widely used tumor response criteria in the clinical setting are the Response Evaluation Criteria in Solid Tumors (RECIST), but in this system, bone metastasis is classified as ‘non-measurable’ and a ‘non-target lesion’ (<a class="elsevierStyleCrossRef" href="#bib10">10</a>). As a result, a readily available biomarker that may enhance the ability to predict the short-term treatment response and long-term survival outcome of NPC patients with bone metastasis is urgently needed.</p><p id="para30" class="elsevierStylePara elsevierViewall">Serum alkaline phosphatase (S-ALP) has been extensively used to screen patients for bone metastasis because it is a simple and inexpensive routine hospital test that is easily available and yields quick results. The prognostic role of S-ALP has been explored in various types of malignancies with bony metastatic disease. Both the baseline S-ALP and changes in S-ALP have been reported as prognostic factors for treatment effect and survival such as in bony metastatic prostate cancer (<a class="elsevierStyleCrossRef" href="#bib8">11</a>), bony metastatic breast cancer (<a class="elsevierStyleCrossRef" href="#bib9">12</a>), and clear cell chondrosarcoma of the bone (<a class="elsevierStyleCrossRef" href="#bib10">13</a>). In our previous study (<a class="elsevierStyleCrossRef" href="#bib11">14</a>), we showed that elevated pretreatment S-ALP was an independently negative prognosticator for disseminated NPC. However, to the best of our knowledge, there is no previous research that has explored the clinical application of S-ALP changes in patients with skeletal metastatic NPC receiving palliative chemotherapy.</p><p id="para40" class="elsevierStylePara elsevierViewall">The aim of this retrospective study was to investigate the prognostic value of S-ALP as a tumor marker in patients with bony metastatic NPC treated with systemic chemotherapy. Pre-treatment and post-treatment S-ALP levels were measured. The correlations of the S-ALP levels to the treatment response evaluation and survival outcome were analyzed.</p><span id="cesec20" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle70">Patients and methods</span><span id="cesec30" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle80">Inclusion criteria and enrollment</span><p id="para50" class="elsevierStylePara elsevierViewall">The charts of 1,380 patients with metastatic NPC admitted to Zhejiang Cancer Hospital between January 2000 and December 2011 were reviewed.

This feature was analyzed as a separate category from the patients who presented with localized disease but then developed metastases at a later date. The SREs were classified as fractures, spinal cord compression, radiation to bone, surgery on bone and hypercalcemia. Progression-free survival (PFS) was defined as the time from the first diagnosis of metastasis to disease progression (newly occurring metastatic lesion, recurrence or the expansion of the primary lesion). Overall survival (OS) was defined as the time from the first diagnosis of metastasis to the time of death. Patients whose deaths were not caused by cancer progression were excluded from the study.</p><p id="para70" class="elsevierStylePara elsevierViewall">S-ALP was estimated using the optimized standard method recommended by the German Society of Clinical Chemistry (<a class="elsevierStyleCrossRef" href="#bib12">15</a>).

Bone metastasis is a pathological status of bone metabolism in which the normal balance between resorption of old bone and formation of new bone is destroyed (<a class="elsevierStyleCrossRef" href="#bib13">17</a>). Following up changes in bone metabolism is crucial because it can provide information for treatment evaluation in patients with skeletal metastases. However, bone density changes occur too slowly to allow the clinician to use an acceptable imaging test to monitor the early response to treatment. X-ray has low sensitivity and can only detect lesions when the diameters of the bone metastatic sites are bigger than 1 cm. Bone scans can detect bone lesions earlier than can X-ray, but this method has low specificity and a high false-positive rate. CT is radiative, PET/CT is expensive, and MRI also suffers from limitations. It is therefore unpractical to use the above means to dynamically monitor the changes in bone metabolism.</p><p id="para230" class="elsevierStylePara elsevierViewall">In recent years, serum markers of bone formation and resorption processes have held great promise as a new means of obtaining the required information. Effective chemotherapy for patients with skeletal metastatic NPC likely has a favorable effect on serum biomarkers of bone turnover, but this impact is still unknown (<a class="elsevierStyleCrossRef" href="#bib18">18</a>–<a class="elsevierStyleCrossRef" href="#bib20">20</a>). Alkaline phosphatase (ALP) is a hydrolase enzyme responsible for removing phosphate groups from many types of molecules, including nucleotides, proteins, and alkaloids. The process of removing the phosphate group is called dephosphorylation. In humans, almost all tissues throughout the entire body contain this enzyme, but it is particularly concentrated in the bone, liver, bile duct, kidney, and placenta. Although ALP is abundant in tissue cells, blood levels of the enzyme are normally low. However, in some pathological and specific physiological situations, they release more ALP into the bloodstream. Conditions that can cause increased ALP in the serum include pregnancy, bile duct obstruction, kidney disease, hepatocellular carcinoma, and bone metastasis (<a class="elsevierStyleCrossRef" href="#bib11">11</a>,<a class="elsevierStyleCrossRefs" href="#bib21">21–24</a>).</p><p id="para240" class="elsevierStylePara elsevierViewall">An elevation of S-ALP is most frequently reported in bone metastasis from certain malignancies, such as lung cancer, breast cancer, and prostate cancer (<a class="elsevierStyleCrossRef" href="#bib19">25-27</a>). Until now, the clinical application of S-ALP in patients with skeletal metastatic NPC has rarely been mentioned. This is the first time the prognostic role and dynamic changes in the significance of S-ALP in disseminated NPC with bone involvement has been explored.</p><p id="para250" class="elsevierStylePara elsevierViewall">The results of this study are consistent with those several of previous studies indicating that the activity of S-ALP is an important prognostic factor for patients with bony malignancies (<a class="elsevierStyleCrossRef" href="#bib20">28</a>,<a class="elsevierStyleCrossRef" href="#bib21">29</a>). In our report, elevated S-ALP levels were significantly correlated with the presence of liver metastasis and skeletal-related events, as well as the involvement of more than one metastatic site. The median PFS and OS in patients with a normal pre-treatment S-ALP level were significantly longer than those with an elevated pre-treatment S-ALP level. The same results were observed as a correlation between the post-treatment S-ALP level and survival outcome. Previous reports have also demonstrated that elevated S-ALP levels are present in both primary and metastatic liver tumors (<a class="elsevierStyleCrossRef" href="#bib30">30</a>). Because the majority of S-ALP consists of isoenzymes derived from liver and bone, it is reasonable that patients with bony metastasis associated with liver involvement have higher S-ALP levels than those with only bone metastasis. The association between increased pretreatment S-ALP activity and skeletal-related events and the involvement of more than one metastatic site also provide a rationale that the negative clinical prognosis associated with elevated pretreatment S-ALP may simply be attributed to a greater initial tumor burden and consequently more advanced tumor stage.</p><p id="para260" class="elsevierStylePara elsevierViewall">As described above, practical imaging techniques for evaluating the treatment response of bone metastases in a timely manner are still lacking. Therefore, we have investigated the predictive value of S-ALP and found that it could serve as a marker to reflect the degree of regression or progression during chemotherapy for the 217 patients who also presented with measurable lesions (with lung or liver metastasis). All 6 patients who achieved CR showed a normal post-treatment S-ALP. Thirty-nine of the PR and 14 of the SD patients showed a sharp drop in S-ALP from an elevated level to a normal level. The response rate was significantly higher in patients with a normal post-treatment S-ALP level compared with those with a sustained high post-treatment S-ALP level. S-ALP levels have been demonstrated to reflect the growth and regression of various malignant neoplasms. Guru Sonpavde et al evaluated the association between changes in the S-ALP within 90 days with OS in men with castration-resistant prostate cancer and bone metastases treated with docetaxel or mitoxantrone in the TAX327 trial. The results showed that the normalization of S-ALP by day 90 predicted better survival and that an increase in S-ALP by day 90 predicted poor survival (<a class="elsevierStyleCrossRef" href="#bib11">11</a>). Maisano R et al reported that in 103 consecutive patients with metastatic colorectal cancer treated with chemotherapy, only 3 patients in the high alkaline phosphatase group obtained a partial response (9.4%) compared to 3 complete responses and 24 partial responses (41.5%) in the low alkaline phosphatase group (<a class="elsevierStyleCrossRef" href="#bib31">31</a>).</p><p id="para270" class="elsevierStylePara elsevierViewall">The Cox proportional hazard regression model revealed that only the pre-treatment S-ALP level and post-treatment S-ALP level were independent prognostic factors for overall survival. Notably, when both the pre-treatment and post-treatment S-ALP were considered during analysis, SREs and vertebral involvement were no longer found to be independent negative factors, as described in our previous research (<a class="elsevierStyleCrossRef" href="#bib5">7</a>). As we reported previously (<a class="elsevierStyleCrossRef" href="#bib11">14</a>), one reasonable explanation is that serum tumor markers can reflect the tumor burden more sensitively and precisely than can the specific site of metastases. Additionally, the various sizes and quantities of the lesions may have different prognostic implications. Numerous large lesions may represent a more extensive spread than that of fewer small lesions. These findings provide a rationale for why S-ALP levels have stood out as an independent prognostic factor for survival outcome.</p><p id="para280" class="elsevierStylePara elsevierViewall">After confirming the prognostic role of S-ALP, we further separated the patients into four subgroups according to their survival outcomes by analyzing the pre-treatment and post-treatment S-ALP in combination. The results revealed that the combination of pre-treatment and post-treatment S-ALP was able to discriminate patients with good prognosis from those with poor prognosis in bony metastatic NPC with or without visceral involvement.</p><p id="para290" class="elsevierStylePara elsevierViewall">There are several limitations in this study. First, because it is a retrospective study, the patients may have had other nonspecific causes of S-ALP elevation. Second, S-ALP is not fractionated to a specific phenotype in the routine test in our center, and therefore, a bone-specific alkaline phosphatase is not available. However, the inclusion criteria of this study required patients with normal renal, cardiac and liver function; hence, it is unlikely that hepatic dysfunction or renal disease is a significant confounding cause of the observed elevations in S-ALP. Another caveat is that the normal ranges of S-ALP differ slightly in different laboratories. We choose a conventionally accepted normal range for ALP of 110 IU/L in this study.</p><p id="para300" class="elsevierStylePara elsevierViewall">In conclusion, S-ALP appears to be a useful marker to predict survival and monitor the response to treatment for bony metastatic NPC. Given that the measurement of S-ALP is a simple, readily quantifiable, inexpensive, and established routine diagnostic test that is easily available with quick results, further prospective research on the usefulness of S-ALP determination for the monitoring of bone metastases is certainly worthwhile.</p></span><span id="cesec150" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle200">AUTHOR CONTRIBUTIONS</span><p id="para310" class="elsevierStylePara elsevierViewall">Jin Y contributed to the study design and manuscript preparation.
