Abstract
PURPOSE To evaluate the effectiveness and toxicity of curative (chemo)radiotherapy in patients with metastatic carcinoma to cervical lymph nodes from an unknown primary. METHODS Retrospective study of 90 consecutive patients, treated with curative radiotherapy from 2003 to 2018 (median age 59 years; current/former smokers 76%) was conducted. The distribution of nodal staging was as follows: N1: 12%, N2a: 21%, N2b: 43%, N2c: 10%, N3: 13%. In 62% of patients, neck dissection was performed before radiotherapy. Concomitant chemotherapy was given to 64% of patients. RESULTS The median follow-up of surviving patients was 86 months. The median total radiotherapy dose achieved was 70 Gy. The 5‑ and 10-year locoregional control were 84% in both cases, while 5‑ and 10-year distant control were 90% and 89%, respectively. A primary tumor in the head and neck area was detected in only 2 patients. No patient had an initial failure in the pharyngeal axis or contralateral cervical nodes. The 5‑ and 10-year overall survival were 55% and 42%, respectively. Severe early toxicity occurred in 71%; severe late toxicity in 33% of patients. Multivariate analysis demonstrated N‑status (hazard ratio [HR] 2.424; 95% confidence interval [CI] 1.121-5.241; p = 0.024) and comorbidity scores assessed by ACE-27 (Adult Comorbidity Evaluation; HR 3.058; 95% CI 1.489-6.281; p = 0.002) as two independent prognostic factors for overall survival. CONCLUSION The results of our work study demonstrate the high effectiveness of curative (chemo)radiotherapy on the pharyngeal axis and bilateral cervical nodes with long-term locoregional and distant control in 3/4 of the treated patients. N‑status and comorbidity scores were shown as strong prognostic factors influencing overall survival.

Abstract
Purpose The optimal practice regarding cervical lymph node biopsy (CLNB) remains to be defined to provide the best clinical management in nasopharyngeal carcinoma (NPC). This study aimed to investigate the effect of CLNB on the survival of NPC patients. Methods Patients diagnosed with NPC from 2004 to 2015 were identified using the Surveillance, Epidemiology, and End Results database. Multivariate logistic regression, Kaplan–Meier method, Cox proportional hazards regression analysis, and propensity score matching (PSM) were used to determine the factors associated with CLNB and prognostic effect of CLNB of NPC. Results We included 1903 patients in this study. There were 321 (16.9%) and 1582 (83.1%) patients with and without CLNB, respectively. The percentage of CLNB was 19.4% in 2004 and was decreased to 8.6% in 2015 (p = 0.044). Patients diagnosed in later years (p = 0.008), older age (p < 0.001), Chinese (p = 0.002), advanced tumor stage (p < 0.001), and early nodal stage (p = 0.003) were less likely to receive additional CLNB. In patients who received additional CLNB, the 5‐years NPC‐specific survival (NPCSS) was 83.6%, which was similar to patients without CLNB (80.1%, p = 0.159). In addition, a similar 5‐years NPCSS was found between those receiving biopsy or aspiration of regional lymph node and those receiving lymph node resection (p = 0.584). There were 187 pairs of patients who were completely matched using PSM, the multivariate prognostic analyses indicated that the receipt of CLNB was not associated with an inferior outcome in the PSM cohort (p = 0.349). Similar results were found after stratification by the year of diagnosis, race/ethnicity, and histology. Conclusion Additional CLNB is not associated with an inferior survival outcome in NPC. Our study provides a reference for the clinical practice of NPC.

J Cancer 2018; 9:2844-2851. [PMID: 30123353 PMCID: PMC6096379 DOI: 10.7150/jca.25505] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2018] [Accepted: 06/09/2018] [Indexed: 12/15/2022] Open
Abstract
Introduction: This study aimed to evaluate the prognostic value of cervical lymph node biopsy and whether different biopsy methods would lead different outcomes in NPC in the intensity-modulated radiotherapy (IMRT) era. Material and Methods: 1492 patients with biopsy-proven, non-metastatic NPC, and treated by IMRT with or without chemotherapy were retrospectively reviewed. Cervical lymph node biopsy was performed in 183 (12.3%) patients: 61(4.1%) by needle puncture and 118(7.9%) by excision biopsy. Propensity-score matching was used to match patients in both arms at an equal ratio. Overall survival (OS), distant metastasis-free survival (DMFS), locoregional relapse-free survival (LRFS), and nodal relapse-free survival (NRFS) were assessed using the Kaplan-Meier method and compared using the log-rank test. Independent prognostic factors were identified using the Cox proportional hazards model. Results: In the original cohort of 1492 patients, patients receiving cervical lymph node biopsy had comparable survival (OS: P = 0.736, DMFS: P = 0.749, LRFS: P = 0.538, NRFS: P = 0.093,) with patients receiving isolated napharynx biopsy. The results for the propensity-match cohort of 316 patients were similar. Interestingly, compared with the control group and needle puncture biopsy group, a slightly lower nodal recurrence rate was observed in the excision biopsy group (P = 0.082 and P = 0.072, respectively). Adjusting for the known prognostic factors in multivariate analysis, cervical biopsy did not cause a higher risk of death, distant metastasis, or nodal relapse. Conclusions: Pretreatment cervical lymph node biopsy is not associated with impaired survival in NPC, suggesting the resist of the biopsy and more aggressive treatment after the biopsy may be unnecessary.

Oncotarget 2018; 8:42372-42381. [PMID: 28418897 PMCID: PMC5522073 DOI: 10.18632/oncotarget.16344] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2016] [Accepted: 02/21/2017] [Indexed: 12/26/2022] Open
Abstract
Background and Objective To evaluate treatment outcomes for patients with retropharyngeal metastatic undifferentiated squamous cell carcinoma (SCC) from an unknown primary site. Methods From January 2005 to January 2015, patients who presented with enlarged retropharyngeal nodes underwent transoral sonography-guided fine-needle aspiration to confirm histology. Those with metastatic undifferentiated SCC with unknown primary tumors were treated with radical radiotherapy to nasopharyngeal mucosa plus bilateral neck. Chemotherapy was administered for patients staged N2-3. Endpoints included metastatic nodes control, the appearance of primary tumor, overall survival and treatment-related toxicities. Results A total of 49 patients were recruited into this study. Retropharyngeal and cervical nodal disease was controlled in 96% of all patients. The incidence of occult primary cancer appearance was 8%. No primary cancer other than of the nasopharynx was detected during the course of follow-up. Ten patients developed distant metastases. The 5-year overall survival, progression-free survival, regional relapse free survival, distant metastasis free survival were 79.6%, 61.1%, 83.4%, 73.8%, respectively. Common late adverse effects included xerostomia (57%) and hearing impairment (35%). Conclusion Radical radiotherapy to both the nasopharynx and bilateral neck can achieve excellent outcome with mild toxicities for patients with retropharyngeal metastatic undifferentiated squamous cell carcinoma from an unknown primary site.

Abstract
This meta-analysis was designed to evaluate radiotherapy (RT) options preferable for neck cancer metastases from unknown primary sites (NCUP). Relevant articles published up through September 2015 were selected from EMBASE, Cochrane, PubMed and Web of Science. Thirty-three articles were identified, and relative risks (RRs) and 95% CIs for all pre-specified endpoints were calculated. Surgery plus RT showed an advantage for 5-year overall survival (OS) (RR 0.66, 95% CI 0.52-0.83, p = 0.0004) and neck recurrence (NR) (RR = 0.74, 95% CI 0.59-0.92, p = 0.008) compared to RT alone. The RRs for NR, primary tumor emergence (PTE), and 5-year disease free survival (DFS) for bilateral neck compared to ipsilateral neck irradiation were 0.61 (95% CI 0.41-0.91, p = 0.01), 0.44(95% CI 0.26-0.77, p = 0.004), and 0.81 (95% CI 0.64-1.03, p = 0.09), respectively. Irradiation of the neck plus potential primary tumor sites (PPTS) showed a benefit for 5-year DFS (RR 0.75, 95% CI 0.61-0.92, p = 0.005), NR (RR = 0.72, 95% CI 0.56-0.92, p = 0.009), and PTE (RR = 0.23, 95% CI 0.12-0.45, p < 0.0001) compared to neck-only irradiation. Adverse events occurred more frequently with bilateral neck plus PPTS irradiation. For NCUP, surgery plus RT of the bilateral neck and PPTS was associated with greater improvement of clinical outcomes.

Abstract
The World Health Organization (WHO) 2017 Classification of Head and Neck Tumors ("Blue Book") will now include a new chapter on tumors and tumor-like lesions of the neck and lymph nodes, which was not included in the previous edition. Tumors and tumor-like lesions, including a variety of cysts and metastases, can arise in any component in the neck, including soft tissue, lymph nodes, and developmental remnants. The pathology and clinical features of metastatic carcinoma of unknown primary in the head and neck has changed dramatically in the last several years. Many of these tumors which were previously diagnosed as unknown primary are now identified as oropharyngeal and nasopharyngeal carcinomas related to human papillomavirus (HPV), less commonly to Epstein-Barr virus (EBV) and occasionally even to Merkel cell polyomavirus. Many unusual features can arise in these metastases, such as undifferentiated morphology, extensive cystic change with central degeneration, gland formation, and even ciliated cells. Rarely, carcinoma in the neck can arise in association with a heterotopic tissue, primarily thyroid or salivary gland tissue. Tumor-like lesions include branchial cleft cysts, thyroglossal duct cyst, dermoid and teratoid cyst, and ranula. Pathologists should be familiar with the diagnostic features and clinicopathologic corrections of these neck lesions in order to correctly diagnosis them and to provide for proper clinical management. This article will briefly describe the pathologic and clinical features of these entities as they are covered in the new 2017 Blue Book.

Abstract
The treatment of carcinomas of unknown primary revealed by cervical lymphadenopathy is based on neck dissection and nodal and pan-mucosal irradiation to control the neck and avoid the emergence of a metachronous primary. The aim of this review was to assess diagnostic and therapeutic approaches and criteria that may be used for a customized selective approach to avoid severe toxicities of pan-mucosal irradiation. A literature search was performed with the following keywords: cervical lymphadenopathy, unknown primary, upper aerodigestive tract, cancer, radiotherapy, squamous cell carcinoma, variants. The diagnostic workup includes a head and neck scanner or MRI, ((18)F)-FDG PET CT, a panendoscopy and tonsillectomy. Squamous cell carcinoma represents over two thirds of cases. The number of metastatic cervical nodes, nodal level, and histological variant (associated with HPV/EBV status) may determine the primary site origin and might be weighted for the determination of radiation target volumes on a multidisciplinary basis. A selective customized approach is relevant to decrease radiation toxicity only if neck and mucosal control is not impaired. Although no recommendation can yet be made in the absence of sufficient level of evidence, the relevance of systematic pan-mucosal irradiation appears questionable in a number of clinical situations. Accordingly, a customized selective redefinition of target volumes may be discussed and be prospectively evaluated in relation to the therapeutic index obtained.

Abstract
Introduction: Metastatic carcinoma in the lymph nodes of the neck from an unknown primary is relatively rare, accounting for about 3% of all head and neck cancers. Management of secondary neck of undetermined primary is controversial. Materials and Methods: The case records of all the patients treated in the Department of Radiotherapy, Chatrapati Shahuji Maharaj Medical University, from Oct 1999 to Sep 2004, were studied and the patients with secondary neck without a known primary tumor were analyzed in detail to elucidate the outcome of various treatment modalities in various stages of the disease. One hundred and forty patients were found to be eligible for this analysis. Initial treatment could be divided into two categories: concurrent chemoradiation (n=76) and radiotherapy alone (n=64). Results: The patients who had received radiotherapy alone (53.1%) had lesser complete response as compared to those who had received chemoradiotherapy (68.4%). The overall survival duration in patients of the radiotherapy treatment group ranged from 5 to 60 months, with an average (±SD) of 31.06 ± 21.01 months, while in the chemoradiotherapy treatment group it ranged from 6 to 60 months, with an average (±SD) of 39.42 ± 21.33 months. Both hematological and nonhematological toxicities, although higher in the chemoradiotherapy group, showed statistically insignificant differences. Conclusion: To the best of our knowledge, this is the only study evaluating the role of concurrent chemoradiation in cases of secondary neck with primary unknown. The improved response rates along with an increased survival (both disease free and overall) show the superiority of chemoradiotherapy in the management of such cases.

Abstract
Imaging plays a chief role in the care and monitoring of patients in cervico-facial oncology. The radiologist must know the anatomy of different lymph nodes as well as signs of malignancy (hypertrophy, enhancement, necrosis, capsular rupture, etc.). CT is still the first-line examination because of its high reliability, its accessibility and its ability to make an assessment of the upper aero digestive ways at the same time. Ultrasound is very accuracy, and allows the realization of cytoponction, but does not provide a complete exploration of the neck. MRI does not appear to be indicated for the first intention, but the new rapid sequences (STIR, diffusion) seem interesting. The PET-CT is useful in post-therapeutic management of patients, and probably in the initial staging, but its accessibility is poor.

Abstract
The objective of this study was to evaluate the efficacy of larynx-sparing radiotherapy (RT) alone or in combination with a neck dissection for patients with squamous cell carcinomas metastatic to cervical lymph nodes from an unknown head and neck primary site. Seventeen patients were treated with curative intent between 1997 and 2002; 16 of 17 patients had follow up for at least 2 years. No patient developed a squamous cell carcinoma in a head and neck mucosal site after treatment. One patient (6%) had persistent nodal disease and 1 patient (6%) had recurrent nodal disease 1 year after completing RT. No patients experienced distant metastases. The 5-year cause-specific and overall survival rates were 88% and 82%, respectively. Based on our limited experience, larynx-sparing RT appears to result in a high likelihood of local-regional control and survival and likely reduces both acute and late toxicity.

Abstract
Patients with malignant cervical lymphadenopathy without an evident primary site are considered to have an unknown primary tumor.Several management concerns arise in this situation including how best to seek a primary site and, if none is identified, how to treat these patients. This article discusses theories as to the etiology of the unknown primary tumor, diagnostic modalities highlighting the role of emerging technologies, and treatment strategies.

Abstract
Cervical lymph node metastases of squamous cell carcinoma from occult primary constitute about 2-5% of all patients with carcinoma of unknown primary site (CUP). Metastases in the upper and middle neck are generally attributed to head and neck cancers, whereas the lower neck (supraclavicular area) involvement is often associated with primary malignancies below the clavicles. The diagnostic procedures include physical examination with thorough evaluation of the head and neck mucosa using fiber-optic endoscopy, biopsies from all suspicious sites or blindly from the sites of possible origin of the primary, computer tomography and/or magnetic resonance. A systematic tonsillectomy in the absence of suspicious lesions is often recommended since up to 25% of primary tumors can be detected in this site. The thoracic primary (tracheal, bronchial, lung, esophagus) has to be excluded, especially in the case of lower neck involvement. Positron emission tomography (PET) with fluoro-2-deoxy-D-glucose allows detection of primary tumor in about 25% of cases, but this procedure is still considered investigational. Therapeutic approaches include surgery (lymph node excision or neck dissection), with or without postoperative radiotherapy, radiotherapy alone and radiotherapy followed by surgery. In early stages (N1), neck dissection and radiotherapy seem to have similar efficacy, whereas more advanced cases (N2, N3) necessitate combined approaches. The extent of radiotherapy (irradiation of bilateral neck and mucosa versus ipsilateral neck radiotherapy) remains debatable. A potential benefit from extensive radiotherapy should be weighted against its acute and late morbidity and difficulties in re-irradiation in the case of subsequent primary emergence. The role of other methods, such as chemotherapy and hyperthermia, remains to be determined.
