- Cervical lymph node metastasis in adenoid cystic carcinoma of oral cavity and oropharynx: A collective international reviewPublication . Suarez, Carlos; Barnes, Leon; Silver, Carl E.; Rodrigo, Juan P.; Shah, Jatin P.; Triantafyllou, Asterios; Rinaldo, Alessandra; Cardesa, Antonio; Pitman, Karen T.; Kowalski, Luiz P.; Robbins, K. Thomas; Hellquist, Henrik; Medina, Jesus E.; Bree, Remco de; Takes, Robert P.; Coca-Pelaz, Andres; Bradley, Patrick J.; Gnepp, Douglas R.; Teymoortash, Afshin; Strojan, Primoz; Mendenhall, William M.; Eloy, Jean Anderson; Bishop, Justin A.; Devaney, Kenneth O.; Thompson, Lester D. R.; Hamoir, Marc; Slootweg, Pieter J.; Vander Poorten, Vincent; Williams, Michelle D.; Wenig, Bruce M.; Skalova, Alena; Ferlito, AlfioThe purpose of this study was to suggest general guidelines in the management of the NO neck of oral cavity and oropharyngeal adenoid cystic carcinoma (AdCC) in order to improve the survival of these patients and/or reduce the risk of neck recurrences. The incidence of cervical node metastasis at diagnosis of head and neck AdCC is variable, and ranges between 3% and 16%. Metastasis to the cervical lymph nodes of intraoral and oropharyngeal AdCC varies from 2% to 43%, with the lower rates pertaining to palatal AdCC and the higher rates to base of the tongue. Neck node recurrence may happen after treatment in 0-14% of AdCC, is highly dependent on the extent of the treatment and is very rare in patients who have been treated with therapeutic or elective neck dissections, or elective neck irradiation. Lymph node involvement with or without extracapsular extension in AdCC has been shown in most reports to be independently associated with decreased overall and cause-specific survival, probably because lymph node involvement is a risk factor for subsequent distant metastasis. The overall rate of occult neck metastasis in patients with head and neck AdCC ranges from 15% to 44%, but occult neck metastasis from oral cavity and/or oropharynx seems to occur more frequently than from other locations, such as the sinonasal tract and major salivary glands. Nevertheless, the benefit of elective neck dissection (END) in AdCC is not comparable to that of squamous cell carcinoma, because the main cause of failure is not relaied to neck or local recurrence, but rather, to distant failure. Therefore, END should be considered in patients with a cN0 neck with AdCC in some high risk oral and oropharyngeal locations when postoperative RT is not planned, or the rare AdCC-high grade transformation.

- Cervical lymph node metastasis in adenoid cystic carcinoma of the larynx: a collective international reviewPublication . Coca-Pelaz, Andres; Barnes, Leon; Rinaldo, Alessandra; Cardesa, Antonio; Shah, Jatin P.; Rodrigo, Juan P.; Suarez, Carlos; Eloy, Jean Anderson; Bishop, Justin A.; Devaney, Kenneth O.; Thompson, Lester D. R.; Wenig, Bruce M.; Strojan, Primoz; Hamoir, Marc; Bradley, Patrick J.; Gnepp, Douglas R.; Silver, Carl E.; Slootweg, Pieter J.; Triantafyllou, Asterios; Vander Poorten, Vincent; Williams, Michelle D.; Skalova, Alena; Hellquist, Henrik; Teymoortash, Afshin; Medina, Jesus E.; Robbins, K. Thomas; Pitman, Karen T.; Kowalski, Luiz P.; de Bree, Remco; Mendenhall, William M.; Takes, Robert P.; Ferlito, AlfioAdenoid cystic carcinoma (AdCC) of the head and neck is a well-recognized pathologic entity that rarely occurs in the larynx. Although the 5-year locoregional control rates are high, distant metastasis has a tendency to appear more than 5 years post treatment. Because AdCC of the larynx is uncommon, it is difficult to standardize a treatment protocol. One of the controversial points is the decision whether or not to perform an elective neck dissection on these patients. Because there is contradictory information about this issue, we have critically reviewed the literature from 1912 to 2015 on all reported cases of AdCC of the larynx in order to clarify this issue. During the most recent period of our review (1991-2015) with a more exact diagnosis of the tumor histology, 142 cases were observed of AdCC of the larynx, of which 91 patients had data pertaining to lymph node status. Eleven of the 91 patients (12.1%) had nodal metastasis and, based on this low proportion of patients, routine elective neck dissection is therefore not recommended.
- Cervical lymph node metastasis in high-grade transformation of head and neck adenoid cystic carcinoma: a collective international reviewPublication . Hellquist, Henrik; Skalova, Alena; Barnes, Leon; Cardesa, Antonio; Thompson, Lester D. R.; Triantafyllou, Asterios; Williams, Michelle D.; Devaney, Kenneth O.; Gnepp, Douglas R.; Bishop, Justin A.; Wenig, Bruce M.; Suarez, Carlos; Rodrigo, Juan P.; Coca-Pelaz, Andres; Strojan, Primoz; Shah, Jatin P.; Hamoir, Marc; Bradley, Patrick J.; Silver, Carl E.; Slootweg, Pieter J.; Vander Poorten, Vincent; Teymoortash, Afshin; Medina, Jesus E.; Robbins, K. Thomas; Pitman, Karen T.; Kowalski, Luiz P.; de Bree, Remco; Mendenhall, William M.; Eloy, Jean Anderson; Takes, Robert P.; Rinaldo, Alessandra; Ferlito, AlfioAdenoid cystic carcinoma (AdCC) is among the most common malignant tumors of the salivary glands. It is characterized by a prolonged clinical course, with frequent local recurrences, late onset of metastases and fatal outcome. High-grade transformation (HGT) is an uncommon phenomenon among salivary carcinomas and is associated with increased tumor aggressiveness. In AdCC with high-grade transformation (AdCC-HGT), the clinical course deviates from the natural history of AdCC. It tends to be accelerated, with a high propensity for lymph node metastasis. In order to shed light on this rare event and, in particular, on treatment implications, we undertook this review: searching for all published cases of AdCC-HGT. We conclude that it is mandatory to perform elective neck dissection in patients with AdCC-HGT, due to the high risk of lymph node metastases associated with transformation.
