Abstract. The prevalence of gastrointestinal metastasis of lung cancer is low. The aim of the present study was to analyze the frequency and clinical characteristics of metastases to the gastrointestinal tract by retrospectively assessing the clinical records of 2,066 patients with lung cancer. A total of 7 patients (0.33%) were diagnosed with gastrointestinal metastasis, including 4 patients with adenocarcinoma, 1 patient with large cell carcinoma and 2 patients with pleomorphic carcinoma. Furthermore, 3 of the patients presented with small bowel metastases, 2 with gastric metastases, 1 with large bowel metastasis and 1 with metastasis of the appendix. The mean time between the diagnosis of the lung tumors and the identification of gastrointestinal metastasis was 13.5 months (range, 3-49 months). The mean time between the identification of the gastrointestinal metastasis and mortality was 100.6 days (range, 21-145 days). In conclusion, the prognosis of patients with recurrence in distant organs, including the gastrointestinal tract, may be worse than patients with recurrence in distant organs, excluding the gastrointestinal tract, particularly those with symptomatic gastrointestinal metastasis. Therefore, the presence of clinical gastrointestinal metastasis may be life threatening; comprehensive evaluations are required to detect and monitor gastrointestinal metastasis during follow-up.
Patient: Male, 70Final Diagnosis: Bilateral adrenal metastasisSymptoms: —Medication: —Clinical Procedure: SurgerySpecialty: SurgeryObjective:Unusual or unexpected effect of treatmentBackground:Although resection of the metastases is the treatment of choice for unilateral solitary adrenal metastasis of non-small cell lung carcinoma (NSCLC), the surgical treatment for bilateral adrenal metastases is quite rare, likely due to the coexistence of multiple synchronous metastases at other sites and/or primary adrenal insufficiency following bilateral adrenalectomy. We herein report a rare case of asynchronous metastasis of NSCLC to the bilateral adrenal glands with long-term survival after bilateral adrenalectomy.Case Report:A 70-year-old male underwent right upper lobectomy for lung adenocarcinomaT2aN2M0, stageIIIA following induction chemotherapy. Forty-four months later, right adrenalectomy of a right adrenal tumor was performed, which revealed metastatic lung carcinoma.Following the administration of adjuvant chemotherapy, a metastatic tumor was detected in the left adrenal gland. Although there were no other signs of distant metastasis on radiological examinations, he underwent the chemotherapy due to the risk of adrenal insufficiency. However, on follow-up CT the adrenal lesion was found to have enlarged; therefore, left adrenalectomy was performed. Three years and six months later, he was doing well, with no evidence of recurrence.Conclusions:Selected patients with solitary adrenal metastases of NSCLC can benefit from an aggressive treatment approach, even if such metastases are bilateral.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
