Current recommendations for treatment of children with IV-S neuroblastoma (NB) indicate that "supportive care is the cornerstone of therapy" and resection of the
primary tumor
is not mandated. The presentation and clinical management of 37 IV-S NB patients from three pediatric oncology centers were retrospectively reviewed. The 22 boys and 15 girls presented at an average age of 107 days (range, 4 to 616 days). Primary tumor sites were identified in the adrenal gland in 19 children, the thorax in 5, the retroperitoneum in 4, and 1 each in the pelvis and kidney. At the time of presentation, metastatic disease was documented in the liver (27), bone marrow (19), skin (7), and regional lymph nodes (7). Massive
hepatomegaly
(below the umbilicus) was demonstrated in 18 patients. Twenty-eight children (76%) have survived on average 90 months following diagnosis. Eight patients (22%) died; six of disease and two of complications of therapy (mean, 9.6 months). One child was lost to follow-up. Only 3 of the 37 patients (8%) were managed solely by supportive care and all are alive. Extirpation of the
primary tumor
was accomplished in 24 individuals (65%). Twenty patients underwent excision at diagnosis and four had delayed resection with few postoperative complications and no deaths related to resection. One death resulted from progression of disease in a child who had tumor removal. Chemotherapy as a single treatment or in combination with radiation was used in 10 children with three children surviving (30%).(ABSTRACT TRUNCATED AT 250 WORDS)

We report the diagnostic, prognostic and therapeutic features of non-Hodgkin's lymphoma in eight patients in whom the disease was seen as a
primary tumor
of the liver. This series illustrates the variety of situations in which lymphoma might be diagnosed: (a) abdominal pain and
hepatomegaly
(three cases), (b) incidental finding at evaluation of a patient with cirrhosis (two cases), (c) secondary neoplasm after treatment for Hodgkin's disease (one case) and (d) complication of AIDS (two cases). In most cases, clinical and/or radiological features were nonspecific. However, the combination of the following features must be considered as suggestive: occurrence of an apparently primary hepatic tumor in an immunocompromised patient, absence of the usual serum tumor markers and increased serum lactic dehydrogenase activity. The final diagnosis was based on histological examination of specimens obtained by ultrasonically guided liver biopsies or at surgery. All cases belonged to unfavorable histological subtypes. Immunohistochemical findings on paraffin-embedded sections demonstrated the B-lymphocyte lineage of the seven tumors available for study. In the three patients without coexisting disease, complete remission was obtained by surgery alone or combined with chemotherapy. In the two patients with coexisting cirrhosis, outcome was rapidly unfavorable, with death occurring less than 3 mo after diagnosis. Among the three immunocompromised patients, two experienced a rapid unfavorable outcome, and the remaining one was in complete remission after surgery and chemotherapy. In conclusion, primary non-Hodgkin's lymphoma of the liver arising in patients without coexisting disease has a slow progression and might be successfully treated by surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

We have evaluated the role of radiotherapy in providing local control of primary tumors and to palliate metastases from neuroblastoma (NB). Fifty-five children with histologically verified NB were evaluated and treated from 1967 to 1984. In univariate analysis, the actuarial survival of eight children with thoracic primaries (85%) was significantly better than the survival of 39 children with intra-abdominal primaries (35%, p = 0.0287). The survival of 28 children less than or equal to 18 months of age at diagnoses was 73%, whereas 27 children older than 18 months had a survival probability of 10% (p = 0.0001). The survival by Evans stage was: I 100% (2 patients), II 85% (7), III 60% (13), IV 4% (27) and IV-S 100% (6). According to the Pediatric Oncology Group (POG) staging system, the survival was: A 100% (3), B 66% (9), C 66% (9), D 23% (34). A multivariable analysis indicated that the Evans staging system was a more powerful indicator of prognosis than the POG system. The analysis also indicated that Evans stage and patient age were independent determinants of survival. The
primary tumor
site did not add significant prognostic information beyond these two factors. Children with Stage I disease were treated with surgery alone. Most children with Stages II and III disease were treated with surgery, irradiation, and Cyclophosphamide or Cyclophosphamide plus Vincristine. All seven patients with Stage II disease received post-operative irradiation to the
primary tumor
and were locally controlled with doses of 4.8 to 26.5 Gy. Eleven of the 13 patients with Stage III disease were irradiated post-operatively. Seven of these 11 patients were locally controlled with doses of 12 to 48.4 Gy. The four Stage III patients with in-field recurrences were older children with large radiotherapy fields and/or low doses administered. The Radiation Therapy Oncology Group pain score system was used to evaluate response of painful bony metastases to irradiation. A response was observed in 65% of the sites irradiated. A response was observed at 67% of the soft tissue metastases irradiated.
Hepatomegaly
causing respiratory embarrassment or inferior vena cava obstruction was treated with irradiation in seven patients. All patients responded with doses ranging from 5 to 24.4 Gy. Five of the 17 children who survived for more than 5 years following treatment had significant scoliosis or kyphosis secondary to vertebral body abnormalities in irradiated bones. All five children were irradiated at a young age with megavoltage equipment.(ABSTRACT TRUNCATED AT 400 WORDS)

The results of management of 14 patients with Stage IV-S neuroblastoma are reported. The treatment policy, although not consistent over this time span, in general used a combination of radiotherapy and chemotherapy or infrequently one modality alone. Twelve of 14 (86%) survived more than 6 years. One patient, with a solitary mediastinal
primary tumor
, died of rapidly progressive disease at three months. The other death occurred in a 4.5-year-old presenting with
hepatomegaly
at diagnosis followed by skeletal dissemination 2.5 years later. Thirteen of the patients were younger than 1 year of age. Of the 11 patients that received radiotherapy, 4 experienced mild asymptomatic scoliosis or kyphoscoliosis at 3 to 12 years after initial therapy. A review of the literature indicates that spontaneous regression in this tumor is very frequent; therefore, it is recommended that for the common presentation of massive
hepatomegaly
in an infant, close observation is warranted, unless life threatening complications occur. However, initial therapeutic intervention may be indicated in those patients with life threatening presentations. This data did not substantiate the necessity for complete surgical excision of the
primary tumor
, as has been suggested by others.

We reviewed the records of 73 patients with primary melanoma of the choroid and ciliary body with metastasis treated at M. D. Anderson Hospital and Tumor Institute between 1973 and 1979. At time of diagnosis of primary melanoma 71 of 73 patients had tumor localized to the eye and were treated with enucleation of the affected eye. The interval from resection of
primary tumor
to detection of systemic metastases in the 71 patients ranged from one to 201 months (median 43.5 months). Weight loss and abdominal pain due to
hepatomegaly
were the most common symptoms, and
hepatomegaly
was the most common physical sign. The liver was the most common site of tumor recurrence, occurring in 44 of 71 patients. Among liver enzymes, serum lactic dehydrogenase was found to be the most sensitive indicator of liver metastasis and was elevated in 96% of patients with tumor in the liver. Liver involvement with tumor was associated with poor response to chemotherapy and significantly poorer survival than involvement of other extracranial sites. The survival duration from time of development of systemic metastasis ranged between one and 31 months (median seven months), with a one-year survival rate of 29%. The median survival of patients from diagnosis of ocular melanoma was 52 months, with a five-year survival rate of 43%.

The records of 207 neuroblastoma patients seen at the Children's Hospital of Philadelphia between 1944 and 1977 were reviewed to study some of the features associated with the unusually good prognosis found in patients with Stage IV-S neuroblastoma. Initially, 22 patients appeared to fit the criteria of small
primary tumor
and distant disease in liver, skin, and/or marrow without evidence of bone metastases; 5 patients were subsequently rejected as being incorrectly staged. The remaining 17 patients had abdominal primary tumors and hepatic disease; in 12 of the 17, an
enlarged liver
was the presenting sign. Six patients had skin lesions, 4 had disease in the marrow on routine smear, and additional sites of spread were pancreas and bowel serosa. The treatment given was not systematic, and it was not possible to correlate any specific form of therapy with a satisfactory outcome. Eleven of 17 patients survived; 6 of 11 survivors had spontaneous regression of all or part of their diseases, 5 of 6 who died received irradiation, chemotherapy, or both. Death usually occurred in the first month as a complication of the local disease; 1 patient succumbed to radiation nephritis. This study establishes that the special pattern of widespread neuroblastoma termed Stage IV-S does exist, and that is associated with a good prognosis. Careful consideration should be given before selecting treatment for the Stage IV-S child because spontaneous regression is likely to occur in most of them. In patients with rapidly enlarging livers, renal or pulmonary complications may develop because of liver bulk or coagulopathies. Treatment should be directed to the liver in these cases because distant metastases seldom supervene. Low-dose irradiation, mild chemotherapy, and possibly surgical release of intraabdominal pressure using a silastic patch have all been effective. Unfortunately, patients occasionally succumb to local disease in spite of these and more aggressive measures.

Surgical widening of the abdomen by a silastic pouch has been used very rarely in the management of critically ill infants with
hepatomegaly
due to neuroblastoma stage 4S. A female newborn baby was referred on the second day of life because of local compressive effects of a massive
hepatomegaly
, which lead to multiorgan failure. An artificial abdominal hernia was created on the third day of life using a silastic pouch. During the operation oxygenation and ventilation improved and urinary output returned. After chemotherapeutic reduction of hepatic metastases and
primary tumor
the pouch was successfully removed on day 57 without local complications. The child has survived for more than 1 year and is in complete remission. An artificial abdominal hernia should be considered more often in the critically ill neonate with stage 4S neuroblastoma and massive
hepatomegaly
.

Liver transplantation (LTx) for metastatic endocrine tumors (MET) remains controversial due to the lack of clear selection criteria. From 1989 to 2005, 85 patients underwent LTx for MET. The
primary tumor
was located in the pancreas or duodenum in 40 cases, digestive tract in 26 and bronchial tree in five. In the remaining 14 cases, primary location was undetermined at the time of LTx.
Hepatomegaly
(explanted liver > or =120% of estimated standard liver volume) was observed in 53 patients (62%). Extrahepatic resection was performed concomitantly with LTx in 34 patients (40%), including upper abdominal exenteration (UAE) in seven. Postoperative in-hospital mortality was 14%. Overall 5-year survival was 47%. Independent factors of poor prognosis according to multivariate analysis included UAE (relative risk (RR): 3.72),
primary tumor
in duodenum or pancreas (RR: 2.94) and
hepatomegaly
(RR: 2.63). After exclusion of cases involving concomitant UAE, the other two factors were combined into a risk model. Five-year survival rate was 12% for the 23 patients presenting both unfavorable prognostic factors versus 68% for the 55 patients presenting one or neither factor (p < 10(-7)). LTx can benefit selected patients with nonresectable MET. Patients presenting duodeno-pancreatic MET in association with
hepatomegaly
are poor indications for LTx.

Hepatocellular carcinoma is a
primary tumor
of the liver, which usually develops in the setting of chronic liver disease, particularly viral hepatitis. The diagnosis of hepatocellular carcinoma can be difficult, and often requires the use of serum markers, one or more imaging modalities, and histological confirmation. The authors describe a case of a 26-year-old woman with hepatocellular carcinoma and multiple pulmonary metastases. She presented with
hepatomegaly
and sporadic fever, and had negative hepatitis serology, normal alkaline phosphatase, and a rising serum alpha-fetoprotein level. The diagnosis was confirmed by histopathology, after percutaneous liver biopsy. Although the patient was in good health condition and had few symptoms, there was no possibility of treatment due to the extension of the liver tumor and the number of pulmonary metastases.

An 18-month-old boy presented with abdominal pain and distension. On physical examination there was a 10 x 7-cm mass in the right upper abdominal quadrant. His alpha-fetoprotein level was 175,000 IU/mL. Abdominal magnetic resonance findings revealed
hepatomegaly
with multiple tumor masses involving nearly all the segments of the liver (PRETEXT IV). The tumor extended through the inferior vena cava and filled 2/3 of the right atrium. Echocardiography revealed normal cardiac function. Histopathologic findings after liver biopsy were consistent with hepatoblastoma. After 6 courses of chemotherapy including cisplatin and doxorubicin (PLADO, SIOPEL protocol), the cardiac tumor regressed completely. The patient's
primary tumor
was then fully resected; no cardiac surgery was performed. After surgery the AFP level was 4 IU/mL and echocardiography revealed normal cardiac function with no residual tumor. The patient has been in remission for 31 months postdiagnosis.
