To evaluate the effect of hepatic resection for metachronous liver metastases after resection of gastric cancer, the clinicopathological factors of gastric cancer, state of liver metastasis, surgical procedures for liver metastasis, and remote survival were studied. Between 1989 and 2001, 30 consecutive patients underwent hepatic resections (36 resections) for metachronous liver metastases. The patients included 25 men and 5 women, and the median age was 60 years old (range 46-86 years old). As for curability, curative A/curative B was 10/20, and H0/H1/H2 was 25/3/2. The mean period from initial surgery to the liver resection was 19.3 months (range 6.3-65.2 months), and the liver metastatic conditions were H1 for 27 patients and H2 for 9 patients. By number of liver metastases, 27 patients had 1 lesion, 24 patients had 2, and 5 patients had more than 3 lesions. Twenty-nine patients were negative and 7 were positive for lymph node metastasis. A partial resection was performed for 13 patients, a subsegmentectomy for 3 patients, a segmentectomy for 7 patients, a lobectomy for 8 patients, and an extended lobectomy for 5 patients. For all patients except those who had other causes of death, the overall mean survival time was 702 days and the 5-year survival rate was 26.4%. There were four 5-year survivors after hepatic resection. In conclusion, the main prognostic factor after resection of metachronous liver metastases was the existence of lymph node metastasis, and the remote survival of patients with abdominal para-aortic lymph node recurrence was poor. The type of liver resection was not a predictor of survival. The resection of liver recurrence was evaluated clinically, but we should maintain strict criteria and select adequate surgical procedures. 相似文献

Axillary lymph node metastasis (ALNM) from esophageal cancer is rare. Its prognosis and effective treatments remain unknown. Between 1997 and 2005, esophagectomy was performed in 361 patients with esophageal cancer in our hospital. ALNM was identified in four patients (1.1%). All patients had left ALNM with ipsilateral left supraclavicular lymph node metastasis. In two patients ALNM developed after radical esophagectomy with regional lymphadenectomy and in the other two patients after chemoradiotherapy of primary lesions. Axillary lymphadenectomy with chemoradiotherapy was given to all patients. Median survival time and disease-free survival (DFS) after initial treatment for primary esophageal cancer were 30.5 months and 11.5 months, respectively. One patient, who had a small number of regional lymph node metastases (two lymph nodes) at esophagectomy and prolonged DFS (22 months) until axillary node recurrence, is still alive, 67 months after axillary lymphadenectomy. The other three patients, who had larger numbers of regional lymph node metastases (average, 8.3) and shorter DFS (average, 9.7 months), died of recurrence an average of 13.3 months after axillary lymphadenectomy. In conclusion, although ALNM is considered a type of distant organ metastasis, if it is a solitary recurrence, good survival may be obtained after appropriate loco-regional therapy. The number of metastatic regional lymph nodes at initial esophagectomy and the duration of DFS until axillary node recurrence can help to guide the decision whether aggressive treatments are warranted. 相似文献

This study aimed to compare the survival of patients with isolated inguinal lymph node metastases from rectal cancer to patients with inguinal and additional synchronous distant metastases from rectal cancer who treated with curative intent. A retrospective review of all consecutive adult patients with rectal adenocarcinoma and inguinal lymph node involvement who underwent curative therapy at our institution from 2002 to 2020 was conducted. Patients were classified as having synchronous inguinal lymph node metastasis (SILNM), or synchronous inguinal lymph node and distant organ metastasis (SILNDOM). Patients in the SILNM group had a median overall survival of 75 months compared to 17.6 months in the SILNDOM group;p-value = 0.09. The recurrence-free survival for patients with SILNM was 19.6 months compared to 2.4 months in the SILNDOM group;p-value = 0.053. In conclusion, SILNM appears to represent a distinct subgroup of patients with metastatic rectal cancer. These patients warrant consideration of treatment with curative intent. Further studies are needed. 相似文献

A study was conducted to evaluate the effect of external radiation therapy on hepatocellular carcinoma (HCC) and its metastatic lesions. A total of 33 patients with cytopathologically proven HCC were subjected to radiation therapy over a 4-year period, and treatment was discontinued in 8 cases due to jaundice, severe discomfort, or early mortality. Thus, 25 patients with 28 lesions underwent irradiation with a total dose ranging between 3000 and 5600. Of these, seven were irradiated for liver tumors, and the results showed that two lesions decreased in size, the symptoms improved in 1 case, and another patient maintained stable disease for 4 months. Among the 21 metastatic lesions treated, only 2 patients failed respond to the treatment. Nine subjects were irradiated for bone metastases, and the bone pain subsided in all but one case. The survival for bone metastasis was as long as 23 months when the primary tumor was treated effectively. Three of the four cases of irradiated skin nodules disappeared and had not recurred after 5 months, 1 year, and 4 years, respectively. Tumor shrinkage or symptoms of relief were noted for three abdominal lymph nodes, one neck lymph node, one pleural tumor, and one lung tumor. Clinical improvement associated with a stable lesion was observed in two patients with brain metastasis. Follow-up revealed regrowth of the tumor or recurrence of symptoms in most of the patients. However, none of the patients died as a direct result of a metastatic lesion. Although external radiation therapy is palliative in intent, it appears to be useful in the treatment of HCC and its metastatic lesions.Presented at The Second International Symposium on Treatment of Liver Cancer.

BACKGROUND: Previous studies have suggested that the prognosis in patients with extremity soft-tissue sarcomas (ESTS) with isolated lymph node (LN) metastases (stage IV) is comparable to that of patients with high-risk ESTS without metastases (stage III). This study was performed to determine the outcomes of patients who underwent aggressive therapy, including lymphadenectomy in patients with LN metastasis from ESTS. METHODS: Demographic details, pathology of the primary disease, timing of LN metastasis, and details of the multimodality treatment were obtained from the medical records of 35 patients with nodal metastasis from ESTS who were treated between 1981 and 2003. Survival after the diagnosis of primary disease and LN metastasis was compared with established historical outcomes for patients with American Joint Commission on Cancer (AJCC) stages III and IV ESTS. RESULTS: Epithelioid sarcomas (23%) and malignant fibrous histiocytomas (23%) were the most common primary histologic types. Twenty (57%) patients presented with synchronous nodal metastasis. Median follow-up from the time of diagnosis of lymph node metastasis was 48.5 months. The 1-year, 2-year, and 5-year actuarial survival rates in patients with synchronous nodal metastasis after lymphadenectomy and additional therapy were 79%, 62%, and 52%, respectively. In comparison, the 1-year, 2-year, and 5-year actuarial survival rates in patients with metachronous nodal metastasis after lymphadenectomy and additional therapy were 100%, 95%, and 66%, respectively. CONCLUSIONS: Patients with isolated regional lymph node metastases who are treated with aggressive approaches, including regional LN dissection, may experience prolonged survival similar to that which more closely approximates the survival seen in patients with stage III disease (5-year survival rate, 50%) rather than the survival seen in patients with stage IV disease (5-year survival rate, 25%). These data lend support for reconsideration of the current AJCC staging system for ESTS. 相似文献

We analyzed the clinical significance of hepatic lymph node metastasis in 48 patients who underwent a resection of colorectal liver metastases with hepatic lymph node (HN) dissection from 2001 to 2010. The frequency and the site of HN metastasis were investigated to clarify the relationship between clinical background and the significance of HN metastasis. In the frequency of HN metastases, positive lymph node metastases were detected in three (9.1%) out of 33 cases with synchronous liver metastasis and in one (6.7%) out of 15 cases with metachronous liver metastasis. In the site of HN metastasis, No. 8a and No. 12a lymph node metastasis was observed in one case each. No. 12b lymph node metastasis was seen in two cases. These cases with the presence of HN metastasis recurred within 13 months. On multivariate analysis using Cox proportional hazards models, hepatic lymph node metastases was an independent risk factor for overall survival (hazard ratio (95% CI): 4.165 (1.018-17.044), p=0.04). Our results indicated that HN metastases in colorectal liver metastases were a poor prognostic factor. Based on the results, we will examine the efficacy of adjuvant chemotherapy for the patients with HN metastases in the future. 相似文献

The prevalence of thyroid metastases in colorectal cancer (CRC) patients is unknown. We retrieved the records of all patients with CRC and pathologically proved thyroid metastasis for the period 1993-2004. Among 5,862 consecutive patients with CRC, 6 (0.1%) were diagnosed with thyroid metastases, a median of 61 months after the diagnosis of primary tumour, and a median of 19 months after the last surgical resection or radiofrequency ablation of other metastases (which were present in all cases). Signs and symptoms, when present (n=3), consisted of cervical pain, cervical adenopathy, goitre, dysphagia, and/or dysphonia. In other cases, the diagnosis was made by positron emission tomography scanning. Thyroidectomy was performed in the 5 patients with isolated thyroid metastases, with cervical lymph node dissection being required in all cases. The only patient treated conservatively because of concomitant liver and lung metastases developed life-threatening dyspnoea, which required emergent tracheal stenting. Median overall survival was 77 months, 58 months, and 12 months after the diagnosis of primary CRC, initial metastases, and thyroid metastasis, respectively. It is concluded that thyroid metastases are rare and occur late in the course of CRC. Thyroidectomy (with cervical lymph node dissection) may result in prevention or improvement of life-threatening symptoms and prolonged survival. 相似文献

BACKGROUND: Hürthle cell neoplasms, often considered a variant of follicular thyroid neoplasms, represent 3% of thyroid carcinomas. Only a handful of publications have focused on the biologic behavior, prognostic factors, and treatment outcomes of Hürthle cell carcinoma. The objective of the current study was to identify the clinical and pathologic features of Hürthle cell carcinomas that predict disease progression or death. METHODS: The authors reviewed medical records of patients who were treated for Hürthle cell carcinoma (HCC) and Hürthle cell adenoma (HCA) at The University of Texas M. D. Anderson Cancer Center from March 1944 to February 1995, including follow-up information. The pathologic diagnosis was confirmed by one of the authors. RESULTS: The authors identified 127 patients with Hürthle cell neoplasms, 89 patients with HCC and 38 patients with HCA. Seven patients with HCC had foci of anaplastic thyroid carcinoma. Survival for this subgroup was worse compared with the overall group and was analyzed separately. The HCC group was significantly older (age 51.8 years vs. age 43.1. years) and had larger tumors (4.3 cm vs. 2.9 cm) compared with the HCA group. No differences were seen in gender or previous radiation exposure. Forty percent of patients in the HCC group died of thyroid carcinoma, whereas no patients in the HCA group died of the disease. There has been no improvement in all-cause and disease specific mortality in the past 5 decades for patients with these neoplasms. Conventional staging systems predicted mortality with minor differences. Of the patients with known metastasis, 38% showed radioiodine uptake. Univariate analysis identified older age, higher disease stage, tumor size, extraglandular invasion, multifocality, lymph node disease, distant metastasis, extensive surgery, external beam radiation therapy, and chemotherapy as factors that were associated with decreased survival. Tumor encapsulation was associated with improved survival. Although radioactive iodine treatment had no overall effect on survival, subgroup analysis showed that patients who received radioactive iodine for adjuvant ablation therapy had better outcomes compared either with patients who did not receive radioactive iodine or with patients who received radioactive iodine as treatment for residual disease. Multivariate analysis indicated that older age and larger tumor size predicted worse survival through an association with worse behaving tumors (multifocal, less encapsulated, and with extraglandular invasion). The decreased survival in patients with lymph node metastases may be explained by its association with distant metastases. The association of extensive surgery, external beam radiation therapy, and chemotherapy with worse survival also disappeared once those factors were analyzed together with other prognostic factors, such as distant metastases. CONCLUSIONS: Several clinical and pathologic prognostic factors were identified in patients with HCC and HCA. Older age and larger tumor size predicted reduced survival. Radioactive iodine therapy may confer a survival benefit when it is used for adjuvant ablation therapy, but not when residual disease is present. The authors could not demonstrate a survival benefit for the use of extensive surgery, external beam radiation therapy, or chemotherapy. 相似文献
