Background Solitary adrenal metastasis from colorectal cancer is rare. Adrenal metastasis is usually detected with synchronous multiple metastases in other organs and is, therefore, considered to be unsuitable for surgical resection. The long-term outcomes of patients with solitary adrenal metastasectomy from colorectal cancer have been reported; however, the survival advantage has not been established. We herein report two cases of curative adrenal resection in patients with solitary adrenal metastasis from colorectal cancer who achieved long-term survival of > 9 years without recurrence after surgical resection. Case presentation The first case involved a 71-year-old man who underwent abdominoperineal rectal resection for rectal cancer. Preoperative CT revealed a mass in the right adrenal, which was growing after surgery. After chemotherapy the adrenal mass decreased in size, and adrenalectomy was performed at 8 months after the first surgery. A pathological examination confirmed metastasis from rectal cancer. The patient received adjuvant chemotherapy and is currently alive without recurrence at 9 years after the adrenalectomy. The second case involved a 53-year-old man who underwent sigmoidectomy for sigmoid colon cancer. Four years later, lobectomy was performed for isolated lung metastasis. Twenty months later, PET-CT revealed solitary metastasis in the left adrenal gland and adrenalectomy was performed. A histopathological examination revealed metastatic adenocarcinoma of sigmoid cancer. Postoperative chemotherapy was administered after adrenalectomy and the patient is currently alive and apparently disease-free at more than 9 years after undergoing adrenal metastasectomy. Conclusion Curative resection for solitary adrenal metastasis from colorectal cancer may be beneficial for survival.
BackgroundAlthough primary duodenal adenocarcinoma (DA) is a rare malignancy representing ~ 0.5% of all gastrointestinal cancers, the incidence of DA is more frequent in Lynch syndrome. Because of its rarity, treatment strategies or optimal chemotherapeutic regimens have not been clearly defined for advanced DA.Case presentationA 72-year-old woman with Lynch syndrome visited our hospital with a right upper abdominal pain. Computed tomography (CT) showed wall thickness with enhancement in the second portion of the duodenum and adjacent abdominal wall, which suggested direct tumor invasion to the abdominal wall. Upper gastrointestinal endoscopy (UGE) showed a large ulcerative tumor in the second portion of the duodenum, and histological analysis revealed a poorly differentiated adenocarcinoma. A cT4N0M0, cStage IIB (Union for International Control Cancer TNM staging) DA was diagnosed. After three courses of chemotherapy with S-1 and oxaliplatin (SOX), follow-up CT and UGE showed shrinkage of the duodenal tumor. Therefore, the patient underwent pancreaticoduodenectomy with lymph node dissection with curative intent. Histological examination showed a pathological complete response to SOX therapy. The postoperative course was uneventful, and the patient was discharged on postoperative day 29. The patient received no adjuvant chemotherapy, and there has been no evidence of recurrence 6 months after the operation.ConclusionsSOX therapy provided a remarkable response and can be an optimal chemotherapeutic regimen for advanced DA in Lynch syndrome.
Background/Aim: This study aimed to investigate the prognostic significance of preoperative anemia in gastric cancer patients. Patients and Methods: The medical records of 801 patients with gastric cancer who underwent gastrectomy at the Nara Medical University hospital, were reviewed. Anemia was defined as a hemoglobin (Hb) level of <10 g/dl. Multivariate analysis was performed to identify prognostic factors. Results: The mean Hb level was 13.1 (SD=2.0). Sixty-four (8.0%) patients were classified into the anemic group. Anemic patients were significantly older than nonanemic patients (p=0.007). Anemia was significantly associated with cardiovascular disease (p=0.041), chronic renal failure (p<0.001), tumor depth (p<0.001), and lymph node metastasis (p=0.001). The overall survival (OS) and cause-specific survival (CSS) rates of anemic patients were significantly lower in comparison to the nonanemic patients (p<0.001). In a subgroup analysis, the OS rate of anemic patients was significantly lower than that of nonanemic patients among patients with stage I and stage II disease. According to a multivariate analysis, preoperative anemia was an independent prognostic factor for OS (p<0.001), but not CSS (p=0.555). The rate of non-cancer deaths among anemic patients was significantly higher than that among nonanemic patients (p<0.001). Conclusion: Preoperative anemia is a simple and reliable predictor of poor prognosis, and it is associated with a higher risk of non-cancer death.
