Metastatic tumors in the oral region: a retrospective chart review of clinical characteristics and prognosis

Treatment strategy for maxillary gingival metastasis arising from gastric adenocarcinoma: A case report and literature review

Gastric cancer metastasizing to the gingiva is rare. The present study reports a case of maxillary gingival metastasis arising from gastric cancer treated with chemotherapy, surgical excision and radiotherapy. A 55-year-old male, who received chemotherapy with trifluridine/tipiracil for treatment of refractory gastric cancer with multiple metastasis, was admitted to the Department of Dentistry and Oral Surgery, Tohoku Medical and Pharmaceutical University Hospital (Sendai, Japan) in December 2023 because of the right side of the maxillary gingival mass presenting with protruding growth. The size of the tumor was ~20 mm. Tumor excision was performed followed by histopathological diagnosis which revealed a metastatic gingival tumor originating from gastric adenocarcinoma. Consequently, the patient underwent a palliative Radiation Therapy Oncology Group 8502 'QUAD shot' regimen. Although there was no progression of oral lesion, the patient died 3 months after diagnosis of gingival metastasis. The present study reviewed previous case records of gingival metastasis originating from gastric cancer and summarized treatment modalities along with clinicopathological association. In conclusion, the prognosis of patients with metastases to the oral region (MOR) is usually unfavorable. For the management of MOR, a multidisciplinary team approach is necessary to develop appropriate treatment strategies. If there are possibilities to improve prognosis or quality of life, the consideration of combination therapy with radical or palliative intent is warranted.

Tumor Metastasis to the Oral Soft Tissues and Jaw Bones: A Retrospective Study and Review of the Literature

OBJECTIVES

Metastasis to the oral soft tissues and jaw is rare and accounts for 1%-3% of maxillofacial malignancies. These lesions usually occur in the context of an extensive malignant tumor with a poor prognosis.

MATERIALS AND METHODS

Archived cases from the Oral and Maxillofacial Pathology Department of the Faculty of Dentistry and two hospital centers of Mashhad University of Medical Sciences were examined. Inclusion criteria were cases with available records of pathologically confirmed metastatic lesions of the oral cavity with or without diagnosed primary malignancy.

RESULTS

Metastatic lesions in the oral cavity and jaw were found in 18 patients, including seven women and 11 men, with a mean age of 49.5 years. Metastatic lesions were more common in the jaw (66%) and particularly in the mandible (38%) than elsewhere. In the case of soft tissue metastases, the gingiva was more affected than other sites. The primary tumor was most commonly in the kidney in men and in the breast in women (36%-28%). In addition, the diagnosis of a metastatic lesion led to the detection of the primary tumor elsewhere in six out of 18 cases (33.3%).

CONCLUSIONS

Early diagnosis of the lesions is challenging, given the absence of specific signs or symptoms, which, in some cases, nonetheless resemble inflammatory, benign, reactive lesions. Therefore, dentists play a crucial role in diagnosing such lesions, as they lead to the discovery of hidden distant primary tumors. Biopsy should always be considered for suspicious lesions, even if the probability is very low.

Radiographic Orofacial Findings of Systemic Diseases

This article discusses the orofacial clinicoradiographic features of systemic diseases that manifest in the orofacial region. The systemic diseases discussed are grouped into the following: autoimmune diseases, endocrine diseases, bone diseases, hematologic diseases, syndromes, and malignancies. The radiographic manifestation ranges from radiolucent bony destruction, increased bone density, calcification, thinning of cortical plate, loss of trabeculation, missing teeth, and supernumerary teeth. It is imperative for clinicians to be cognizant of these findings, as they may be the first manifestation of these systemic diseases.

Metastatic colon carcinoma in the maxilla: Highlighting the importance of perioperative oral management: A case report

Metastatic colorectal carcinoma involving the maxilla is a rare phenomenon, and existing literature regarding the significance of perioperative oral function management (POM) in managing such cases is limited. In the present case report the clinical details of a 58-year-old male referred to the oral and maxillofacial department for POM. The patient had previously undergone segmental bowel resection due to stage IIIb colon cancer. A comprehensive approach encompassing a thorough medical history, meticulous physical examination, radiographic imaging and immunohistopathology was employed, and a definitive diagnosis of metastatic adenocarcinoma in the left maxillary gingiva originating from a colorectal carcinoma was reached. Additionally, concomitant metastases were detected in the lungs and liver. Despite the daunting prognosis associated with the metastases in the oral cavity, the patient's quality of life exhibited discernible improvements owing to the implementation of palliative care interventions. Notably, this interdisciplinary approach facilitated the patient's survival for over a year. The present case report strongly advocates for the prompt integration of POM in the surgical management of cancer patients with oral manifestations, which can optimize both the quality of life and overall survival.

Metastatic Tumors to the Oral Soft Tissues and Jawbones: A Retrospective Analysis of 40 Cases and Review of the Literature

BACKGROUND

Metastasis to the oral soft tissues and jawbones is rare and frequently associated with wide spread disease and dismal prognosis. Herein, we report the clinicopathologic characteristics of 40 intraoral metastatic neoplasms and perform a comprehensive review of the pertinent literature.

METHODS

Criteria for inclusion included: (a) archived cases from the UMN Oral Pathology laboratory with available tissue blocks and/or H&E-stained preparations diagnosed between 2003 and 2021, (b) proper documentation of the clinico-radiographic characteristics of oral metastasis along with confirmed history of primary malignancy, or (c) microscopic findings consistent with metastatic disease with or without discovery of the primary site.

RESULTS

Intraoral metastases comprised 0.03% of all accessioned cases; 22 (55%) occurred in men and 18 (45%) in women (median age = 66.5; range = 18-94 years). Eighteen cases (45%) involved the gingiva, 16 (40%) the gingiva and jawbones, 5 (12.5%) were exclusively intraosseous, and 1 affected (2.5%) the tongue. The lung was the two most frequent primary site in both men (n = 6, 27.3%) and women (n = 5, 27.7%), followed by the colon (n = 4, 18.2%) and kidney (n = 3, 13.7%) in men, and colon (n = 4, 22.2%) and breast (n = 3, 16.6%) in women. Analysis of 1,084 metastatic cases from the literature (male-to-female ratio = 1.2; mean = 52.3; range = 0.6-90 years) indicated strong preference for the jawbones (69.5%) and significant site-specific predilection of certain primary malignancies.

CONCLUSIONS

Oral and gnathic metastases are rare but demonstrate a clear predilection for the gingiva and mandible. Clinicians should remain cognizant of such lesions since they frequently mimic inflammatory, reactive or benign neoplastic processes and, in certain cases, are the first indication of occult disease.
