The findings of 247 pediatric patients who presented with supradiaphragmatic Hodgkin's disease and underwent staging laparotomies between April 1969 and December 1991 were reviewed to assess the importance of the staging laparotomy in pediatric Hodgkin's disease. A change in stage occurred in 25% of the cases reviewed. Fifty of the 202 (25%) clinical stage (CS) I or II patients were upstaged to pathological stage (PS) III or IV, and 12 of the 45 (27%) clinical stage III or IV patients were downstaged to pathological stage I or II. Possible risk factors for positive surgical staging, including gender, age, presence or absence of B symptoms, extent of involvement above the diaphragm, and histological type, were used to define subgroups of patients. Three statistically significant subgroups of patients with less than a 10% chance of restaging were identified. These groups included CS I and II patients with lymphocyte-predominant histology, CS I females, and CS III and IV females with nonlymphocyte predominant histology. These subgroups represent 24% of the cohort. Because CS is an accurate predictor of PS in these groups, treatment could be based solely on CS. The impact of radiographic imaging techniques on correctly predicting pathological stage was assessed. The rates of restaging for individuals with lymphangiography or computed axial tomography were not statistically different from those of patients without these radiographic studies. Therefore, abdominal imaging is not a substitute for surgical staging. No mortality and 2.8% morbidity occurred from staging laparotomy. Postsplenectomy sepsis and small bowel obstruction were the most common complications. Ninety-six percent of upstaged patients had splenic involvement, and 54% had positive nodal involvement.(ABSTRACT TRUNCATED AT 250 WORDS)

From 1977 to 1990, 94 evaluable patients were treated with iridium-192 implantation in the Centre Claudius Regaud for a Stage I (52 patients) or a Stage II (42 patients) squamous cell carcinoma of the mobile tongue and/or the floor of the mouth. Interstitial brachytherapy was associated with external irradiation in 68 patients (group 1; mean dose, 48 Gy for external irradiation, 26 Gy for brachytherapy) or was exclusive in 26 patients (group 2; mean dose, 66 Gy). The mean follow-up was 44 months. Eleven acute complications were noted during or immediately after the implant (1 lethal myocardial infarction, 6 hematomas of the tongue which spontaneously resolved, 3 local sepsis). The mean duration of the mucositis was 9 weeks (from 4 to 20 weeks). Ten patients (17%) experienced a late complication (8 in group 1, 2 in group 2): 3 bone necroses requiring hemimandibulectomy (1 post-operative death), 1 tongue necrosis treated by a transoral mucosal excision, 6 bone expositions which recovered after medical treatment. Local control rates for T1 and T2 tumors were 75% (39/52) and 51% (21/41), respectively. Sixteen patients (17%) presented a nodal relapse which was associated in 6 cases with a concomitant local relapse. The local control rate of T1 tumors was 64% (23/36) in group 1 versus 100% (16/16) in group 2 (p < 0.01). For T2 tumors, these figures were 45% (14/31) and 70% (7/10), respectively (p > 0.3). The influence of 13 parameters on the local control was studied in analysis. In the one model analysis, a cox regression tumor size was significantly predictive of actuarial local recurrence (p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Several authors have reported cases of patients with malignant lymphoma with unique characteristics, designated nasal-type T/NK cell lymphoma, which expresses the natural killer (NK) cell marker and shows frequent extra-nodal involvement and poor prognosis. We report 2 cases of this type of lymphoma which were CD56-positive and showed a histopathologically angiocentric pattern with cutaneous and subcutaneous tumorous lesions. Patient 1 had extensive invasion of skin, underlying skeletal muscle, spleen and bone marrow, and died of sepsis 34 months after onset. Patient 2 had multiple subcutaneous nodules and invasion to mammary gland, lung, lymph node and spleen at the time of her first visit. She died of a rapid invasion of lymphoma cells to the liver 5 months after onset. Both patients showed similar immunophenotypes of tumor cells (CD2+, CD3-, CD4-, CD8-, CD20-, CD56+) and germ line configuration of the heavy chain of immunoglobulin (JH), T-cell receptor C beta-1 subunit DNA and T-cell receptor J gamma subunit DNA. Epstein-Barr virus early regions RNA was demonstrated in the nuclei of tumor cells of both patients with in situ hybridization. The histopathological examination of the skin lesions of both patients revealed the features of angiocentric lymphoma. The detection of CD56 in the tumor cells of cutaneous lymphomas should be routinely performed for the early diagnosis of this type of lymphoma with extremely poor prognosis.

We report long-term results of high-dose cyclophosphamide, etoposide and carboplatin with ABMT in 20 patients with metastatic breast cancer. Median age of the group was 41 years, ECOG performance status = 0 in 18 patients and 1 in two patients. Twelve patients had received adjuvant chemotherapy. Predominant sites of metastases were lung (eight), chest wall (four), liver (four), bone (three) and lymph nodes (three). Response to pretransplant chemotherapy was complete (CR) in four patients, partial (PR) in 10 patients and stable (SD) in five patients. After high-dose chemotherapy eight patients were in CR, six PR, four SD and one progressive disease. Two patients died of regimen-related toxicities (candidal sepsis and alveolar hemorrhage). With a median follow-up period of 55 months (minimum 48 months), 12 patients have died of recurrent breast cancer, one died of toxicity of salvage chemotherapy, two are alive with disease, two are alive and free of progressive disease. One patient with relapsed disease was lost to follow-up. Median event-free survival is 6 months and median overall survival is 17 months. All three of the long-term disease-free survivors had predominantly nodal disease. Two of these three patients presented with metastatic disease and received high-dose chemotherapy with ABMT as part of initial therapy for breast cancer; two of three attained CR to standard-dose cytoreductive therapy; none received doxorubicin-containing adjuvant chemotherapy.

Between 1980 and 1997, 1194 patients with a malignant tumor of the lower esophagus have been observed and treated in our Institution. There were 555 patients (46.5%) presenting with squamous-cell carcinoma, 101 (8.5%), with Barrett's adenocarcinoma and 538 (45%) with cardia adenocarcinoma. Most patient underwent a transthoracic esophagectomy with esophagogastroplasty; transhiatal approach was mainly reserved to high-risk patients. Over the past two years sixty-three patients (42 with adenocarcinoma and 21 with squamous cell carcinoma) underwent enlarged mediastinal lymphadenectomy. Three patients (4.7%) died post-operatively: one sepsis, in pulmonary embolism and one myocardial infarction. Four patients (6.3%) developed pulmonary complications: no patient had recuriential palsy. Pathologic exam revealed 1342 nodes (807 thoracic and 827 abdominal). Twenty patients (31.7%) had mediastinal nodal metastases, of which 8 in the upper mediastinum. Median follow-up was 19 months (2-36 months). Seven of the sixteen patients with recurrent disease (12 systemic, 3 mediastinal and 1 anastomotic) died. The number of metastatic nodes increased with serial section and even more with immunohistochemical staining technique (from 11.7% to 13% to 15.5%, respectively). Two patients were up-staged from M0 to M1 because of peripancreatic nodal micrometastases. We conclude that enlarged mediastinal lymphadenectomy allowed to detect upper mediastinal lymph node metastases in 12.8% of patients without increasing post-operative complication rate. A longer follow-up is required to evaluate the impact on long term survival.

Although pancreatectomy is still performed in a few patients with pancreatic cancer, and nearly all patients who develop pancreatic cancer eventually die of their disease, significant improvements have been made recently. Pancreatectomy is now safer, with major morbidity (hemorrhage, pancreatic anastomotic leak, intraabdominal sepsis) occurring in only about 20% and operative mortality of less than 5%. Two (seemingly subtle) issues cannot be overemphasized when someone carefully studies the literature: (1) There is a crucial difference between actuarial and actual survival, with the former generally being higher whereas the latter is true; and (2) careful re-review of pathologic specimens (especially in long-term survivors) initially diagnosed as pancreatic cancer, preferably by an independent pathologist before publishing long-term results is essential. (Erroneous inclusion of patients with nonductal carcinoma substantially and artificially increases survival.) After curative resection, 5-year actual survival is realistically about 10% with median survivals of 12 to 18 months. In certain subgroups with favorable pathologic characteristics (neoplasms <2 cm without nodal or perineural invasion) the prognosis appears to be significantly better, with the 5-year survival about 20%. The recent improvements in postoperative morbidity and mortality and long-term outcome (resulting also in decreased cost of care of such patients) have occurred typically in centers with an invested interest in and proven record with pancreatic surgery. Further improvements in survival should be sought at the areas of earlier diagnosis and novel treatments designed to prevent locoregional recurrences; the role of extended resections must be determined by prospective, randomized trials.

To evaluate the etiology and differential features of intrathoracic lymphadenopathy (LAD) in HIV patients, chest computed tomography (CT) records from an 18-month period were reviewed to identify all HIV-positive patients with intrathoracic LAD (nodal size > or = 1 cm). Medical records were reviewed for the documentation of specific diseases causing LAD and the CD4 count at the time of imaging. Of 45 HIV-positive patients with LAD, 40 had specific diagnoses including 22 (55%) infections and 17 (43%) tumors; one patient had both (3%). Mycobacterial disease accounted for 78% of infections; five cases were secondary to bacterial pneumonia and sepsis. Of tumors, lymphoma (7 cases, 39%) was most common, followed by lung cancer, germ cell tumors, and Kaposi's sarcoma. Mean CD4 cell count in patients with tumors was much higher than in patients with infections (314 vs. 62, p < .01). Patients with tumors were somewhat more likely than patients with infections to demonstrate axillary adenopathy (29 vs. 5%, p = .068). Cavitary disease was only observed in patients with infections (27%, p < .03). CT and clinical findings may help direct the differential diagnosis of LAD in AIDS, and promote expedient definitive diagnosis and therapy.

Primary cutaneous B-cell lymphomas (PCBLs) may have particular clinicopathologic characteristics distinct from their lymph node-based counterparts. It has been suggested that PCBLs should have a separate classification system. The aim of this study was to determine whether the Revised European-American Lymphoid Neoplasms (REAL) classification is applicable to PCBL. Thirty-nine cases of PCBL from 36 patients, consisting of 20 men and 16 women (median age 66 yrs), were included in this study. Paraffin-section immunohistochemistry for CD3, CD5, CD10, CD20, CD43, Bcl-2, Bcl-6, and cyclin D1 was performed in all cases. Immunostaining for immunoglobulin light chains was also performed on cases histologically diagnosed as extranodal marginal zone lymphoma (MZL) and primary cutaneous B-cell lymphoma unclassifiable (PCBLu). Polymerase chain reaction (PCR) analysis of t(14;18) was performed in all cases. Immunoglobulin heavy chain gene rearrangement (VDJ) was tested by PCR on all follicle center lymphoma (FCL), MZL, and PCBLu cases. The 39 cases consisted of 15 (39%) FCLs, 13 (33%) diffuse large B-cell lymphomas (DLCL), 9 (23%) extranodal MZL, and 2 cases of PCBLu. Anatomically, 59% of PCBLs occurred in the head and neck, of which approximately 57% were FCL. Five of six cases presenting on the lower extremity were DLCL. Follow-up data was available from all 39 patients with a mean of 50.8 months. All but two patients are alive with or without disease at last contact. One patient with DLCL died of lung metastases and the other DLCL patient died of sepsis as a complication of therapy. In all 15 cases of FCL, CD10 and/or Bcl-6 expression supported the follicle center origin of the neoplastic cells. In contrast to previous reports, we found that 53% (8 of 15) of primary cutaneous FCL had either Bcl-2 protein expression or t(14;18). Our data indicate that many cases of primary cutaneous FCL have Bcl-2 alterations similar to their nodal counterpart. We found that 95% (37 of 39) of PCBLs could be classified according to the REAL classification, supporting its applicability in cutaneous lymphomas.

Profound hypothermia (core temperature of less than 28 degrees C) is a life threatening state and a medical emergency associated with a high mortality rate. The prognosis depends on underlying diseases, advanced or very early age, the duration prior to treatment, the degree of hemodynamic deterioration, and especially, the methods of treatment, including active external or internal rewarming. This is a case study of an 80-year-old female patient with severe accidental hypothermia (core temperature 27 degrees C). She was found in her home lying immobile on the cold floor after a fall. The patient was in a profound coma with cardiocirculatory collapse, and the medical staff treating her was inclined to pronounce her deceased. On her arrival at the hospital, she was resuscitated, put on a respirator and actively warmed. Very severe metabolic disorders were found, including a marked metabolic acidosis composed of diabetic ketoacidosis (she had suffered from insulin treated type 2 diabetes mellitus) and lactic acidosis with a very high anion gap (42) and a hyperosmotic state (blood glucose 1202 mg/dl). There were pathognomonic electrocardiographic abnormalities, J-wave of Osborn and prolonged repolarization. Slow atrial fibrillation with a ventricular response of 30 bpm followed by a nodal rhythm of 12 bpm and reversible cardiac arrest were recorded. The pulse and blood pressure were unobtainable. Despite the successful resuscitation and hemodynamic and cognitive improvement, rhabdomyolysis (CKP 6580 u/L), renal failure and hepatic damage developed. She was extubated and treated with intravenous fluids containing dopamine, bicarbonate, insulin and antibiotics. Her medical condition gradually improved, and she was discharged clear minded, functioning very well and independent. Renal and liver tests returned eventually to normal limits. Progressive bradycardia, hypotension and death due to ventricular fibrillation or asystole commonly occur during severe hypothermia. Respiratory and metabolic, sometimes lactic, acidosis, lethargy and coma, hypercoagulopathy, hyperosmolar state, acute pancreatitis and renal and hepatic failure are frequent complications of hypothermia. Underlying predisposing causes of hypothermia are diabetic ketoacidosis, cerebrovascular disease, mental retardation, hypothyroidism, pituitary and adrenal insufficiency, malnutrition, acute alcoholism, liver damage, hypoglycemia, sepsis, hypothalamic dysfunction, sepsis and polypharmacy, and especially, the use of sedative and narcotic drugs. Our case demonstrates once again that CPR once begun should continue until the successful rewarming because "no one is dead until warm and dead".

Definitive surgical treatment should never be undertaken without a histological confirmation of the diagnosis. For operable disease primary treatment is normally breast-conserving surgery or mastectomy, in association with axillary surgery. Patients with larger technically operable tumours may be treated with primary chemotherapy to try to shrink the tumour so that less radical surgery can be undertaken. The objective of surgery is clearance of local and regional disease with a margin of clear tissue, and to achieve an acceptable cosmetic outcome. Clinical assessment of the axilla is unreliable and because of the prognostic significance of the axillary nodal status this has to be determined histologically. Patients with single tumours < or = 4 cm are suitable for conservation therapy but this will depend on breast size. After excision with clear margins and subsequent radiotherapy the breast recurrence rate should not exceed 5-10% at 10 years. Patients will require mastectomy because of disease extent, breast size, or for personal reasons. The usual operation is a total mastectomy with axillary clearance but small islands of breast tissue may persist subcutaneously as potential sites for future disease. Good breast-conserving surgery is invariably better than reconstruction but, in the event of a mastectomy, reconstruction is offered either as an immediate or a delayed procedure. Complications of any form of surgery include haematoma, wound sepsis and wound flap necrosis. Specific complications are collections of serous fluid in the axilla or in the wound itself (seroma), shoulder stiffness and cording caused by distal thrombosis of lymphatics or veins after axillary dissection. The intercostobrachial nerve is often divided during surgery, causing numbness of the inner upper arm. Some degree of lymphoedema of the arm occurs in 10-15% of patients treated with axillary surgery. It is usually mild and may become rare as more patients have sentinel node biopsies.
