Patients who had a primary tumor at a different site with metastasis to the head or neck were not included in the analysis.
Since previous studies have reported increased microvascular permeability in tumors or diseased nodes (Padhani et al., 2000; Yao et al., 2011; Chang et al., 2008), we hypothesized that nodal DCE-MRI parameters, which reflect the microvascular permeability in regional metastatic lymph nodes, correlate with nodal stage and the DCE-MRI parameters in the primary tumor which is an indicator of tumor aggressiveness.
The patient received five cycles of induction chemotherapy, high-dose chemotherapy (HDC) with autologous peripheral blood stem cell transplantation (auto-PBSCT), followed by surgical resection of the primary tumor together with renal biopsy, and finally cranial irradiation (Table 1).
Removal of the primary tumor in that subgroup of patients has been usually reserved to cases in which palliation was deemed necessary due to local complications, while it has been historically avoided in patients with asymptomatic breast cancer.
We conducted a retrospective study to determine the incidence and treatment outcomes of neck metastases inpatients with squamous cell carcinoma (SCC) of the hard palate and/or maxillary alveolus after surgical excision of the primary tumor. We also sought to identify any risk factors for recurrence.
Background: Controversy exists over whether aggressive surgical resection of the primary tumor without metastasectomy first or chemotherapy first in stage IV colon cancer with unresectable synchronous liver-only-metastases (CLM) improves patients.
Any second primary tumor found more than 6months after the discovery of the index tumor was termed a metachronous tumor.
Expression of both the ERCC1 protein or the ERCC1 transcript has been extensively studied in primary tumor tissue of several cancer entities and has been proposed as a potential predictor for response to platinum-based chemotherapy.
"Metastasis, not the primary tumor, kills about 90 percent of cancer patients," said David Zaharoff, assistant professor of biomedical engineering and the head of the project.
Traditionally, these patients underwent surgery to remove the primary tumor and a rim of normal tissue around it, followed by clinical observation of the lymph nodes throughout their follow-up care, or until the disease was detected in the lymph nodes.
