Study the survival of patients with cervical lymphatic squamous cell carcinoma recurrence. Review of tumor registry database. Academic health science center. Forty-seven isolated neck recurrence patients identified from 224 recurrences from a total of 1291 patients treated between 1998 and 2007. The main outcome measurements were neck lymph nodal recurrence, treatment-specific survival, and overall survival. A total of 47 patients had neck recurrence; 10 of the neck recurrence patients (21.3%) had regional disease (N+) at initial presentation. Median survival for patients with neck recurrence was 14.7 months (95% confidence interval [CI] 8.6-18.1 mo), and five-year survival for this group was five percent (95% CI 0%-30%). Neck dissection salvage therapy for neck recurrence resulted in the best survival. Neck dissection as a salvage therapy for neck recurrence resulted in the best survival, and there was no survival benefit in terms of whether a patient had a neck dissection or not as his or her initial therapy.
Update of assessment of survival in head and neck cancer after regional recurrence
Journal of oncology, 2012
Objective. To evaluate site of regional recurrence in patients with squamous cell carcinoma of upper aerodigestive tract after neck dissection and the results of salvage treatment. Methods. 95 patients with regional recurrence as the first manifestation of relapse were selected between 943 patients who underwent neck dissection. We evaluated level and side of recurrence, as well disease control after salvage treatment. Results. Level II was the most frequent site of recurrence. Salvage treatment was performed in 51% of ipsilateral and in 75% of contralateral (nondissected neck) recurrences. Control of the disease 12 months after salvage surgery was 25% in the ipsilateral and 37% in contralateral recurrences. Conclusions. Cervical recurrences occur predominantly in level II. Relapse in level I is frequent only in oral cavity tumors and relapse in level V is rare. The neck recurrence carries a poor prognosis even among patients who underwent retreatment with curative intent.
The Treatment of Neck Cancer Depends on the Stage of the Cancer
The average age of people who have neck cancer is 59 years. In general, cancer of the salivary glands or thyroid affects people under the age of 59, and cancer of the mouth, throat and larynx affects those over the age of 59. Usually, head and neck cancer first spreads to nearby lymph nodes. These forms of cancer do not usually spread to other parts of the body for 6 months to 3 years. Metastases usually arise from large or persistent tumors and are more likely to develop in people who have a weakened immune system. Treatment depends on the stage of the cancer. Stage I cancer, regardless of location, responds similarly to surgical treatment and radiation. Usually, radiation targets not only the cancer but also the lymph nodes on the circumference of the neck because more than 20% of such cancers spread to the lymph nodes.

A prospectively recorded series of 107 patients with clinical neck node metastases from head and neck squamous cell carcinomas, treated in 1983-1988, and with initial local control, is evaluated. Eighty-eight patients received preoperative, and were operated 4-6 weeks after radiotherapy, and 19 received postoperative radiotherapy. Forty-four of the neck specimens in the preoperatively treated patients showed vital tumor tissue, 7 with positive and 37 with negative resection margins. Nine of the latter 37 patients died due to regional recurrence. Twenty-three of the preoperatively treated patients had no palpable residual tumor following radiotherapy, but histological examination showed vital tumor tissue in five, of whom two had N1 neck disease. The overall regional failure rate was 19%. Eleven patients (10%) died from local recurrence and 11 from distant metastases. Forty-one patients (38%) are alive without evidence of disease and three (3%) alive with disease (mean observation time 30 months). Combined treatment is recommended for all cases of neck node metastases.
Contemporary management of head and neck cancers
The Israel Medical Association journal : IMAJ, 2009
Head and neck cancer is the sixth most common cancer worldwide. HNCs can originate in the skin or soft tissue, in the upper aerodigestive tracts (oral cavity, oropharynx, hypopharynx, larynx, nasopharynx, paranasal sinuses, salivary glands), or in the thyroid. In each of these sites, tumors vary not only by the primary site but also by pathophysiology, biological behavior, and sensitivity to radiotherapy or chemotherapy. Management should be planned according to the tumor's characteristics, patient factors and expertise of the medical team. The main goals of therapy are ablation of the cancer while minimizing morbidity and preserving function and cosmesis. A multidisciplinary team is needed to achieve these goals. Early-stage HNC (stage I and II) should be managed with a single modality, and advanced tumors (stage III and IV) with multimodality therapy. Treatment should be directed to the primary tumor and the area of its lymphatic drainage--the neck lymph nodes. Evidence of met...

The pattern of clinical behaviour and response to treatment of recurrent and/or metastatic head and neck squamous cell carcinoma is heterogeneous. Treatment strategies that can be employed vary from potentially curative salvage surgery and re-irradiation to palliative systemic therapies and best supportive care. The advent of new therapeutic options, in terms of more sophisticated surgical approaches and techniques, highly conformal and precise radiation techniques and immunotherapy may offer improved control of disease and longer survival. Moreover, the epidemiological changes during the last decades, including the increase of human papilloma virus-related oropharyngeal primary tumors, are also reflected in the recurrent and metastatic setting. In this complex context the identification of predictive and prognostic factors is urgently needed to tailor treatment, to increase its efficacy, and to avoid unnecessary toxicities. A better knowledge of prognosis may also help the patients and caregivers in decision making on the optimal choice of care. The purpose of our review is to highlight the current evidence and shortcomings in this field.

Purpose Debate on the extent of treatment of neck metastasis of cancer of unknown primary tumors (CUPs) is still ongoing. In two Dutch tertiary referral centers, the post-surgical radiation target volume changed from the bilateral neck including the pharyngeal axis to the unilateral neck only, in the course of the last decade. This study aims to investigate the outcome of patients with CUP before and after de-escalation of post-surgical radiotherapy. Methods Data of two Dutch tertiary referral centers were merged. Disease-free survival (DFS), overall survival (OS), and regional control rate (RCR) of 80 patients diagnosed with CUP (squamous cell and undifferentiated carcinomas) between 1990 and 2009 were retrospectively analyzed. Results Thirty patients received bilateral neck and pharyngeal axis radiotherapy and 42 patients ipsilateral radiotherapy only. In another eight patients, the postsurgical radiation target volume was expanded to the contralateral neck or to the pharyngeal axis, due to suspicious lesions on imaging. The 5-year DFS, OS and RCR were 60%, 51.2%, and 80%, respectively, in the total patient population. RCR did not differ in patients treated with ipsilateral as compared to bilateral radiotherapy nor did 5-year OS and DFS. No tumors occurred in the pharyngeal axis. Conclusion In this study, omitting elective treatment of the contralateral neck and pharyngeal axis did not lead to a decrease in locoregional control or survival rates when treating patients with CUP.
Squamous cell carcinoma of the head and neck: Management of the NX neck
International Journal of Radiation Oncology*Biology*Physics, 1991
Purpose: The judiciousness of open biopsy of lymph node mestastases in the neck is controversial. A retrospective review of treatment results at the University of Florida in patients who underwent excisional biopsy of a solitary metastatic neck node followed by radiotherapy was undertaken to determine whether the approach resulted in increased rates of regional and distant recurrence or wound complications. Methods and Materials: Between October 1964 and September 1987, 41 patients were referred for radiotherapy after excisional biopsy of a solitary cervical node containing metastatic squamous cell carcinoma from a known mucosal site (19 patients) or unknown primary (22 patients) in the head and neck. None had known gross residual neck disease. The neck stage (based on N stage before surgery or size of the excised node) was unknown in seven patients, Nl in 15 patients, N2A in 18 patients, and N3A in one patient. All patients received radiotherapy to the neck and two had a planned neck dissection after radiotherapy. Doses to the nodal bed ranged from 5485 cGy to 8100 cGy (median, 6675 cGy). Results: The probability of control of neck disease was 95% at both 5 and 10 years. Five-year probability of disease control above the clavicles was 90%. Distant metastasis occurred in 0 of 36 patients whose disease was controlled above the clavicles vs. 3 of 5 patients who suffered failure above the clavicles. Conclusion: Excisional biopsy of a solitary neck node followed by radiotherapy produced excellent regional control and no apparent increased rate of distant metastasis.
